Foreword

T

he global scene is quite different today to how it was in 2000 when the first Environment Outlook for Latin America and the Caribbean was published. Security has become the main agenda for the global community, making it even more difficult to ensure adequate coverage and financing of environmental issues. At the same time, countries are grasping for ways to reap the rewards of globalisation while limiting its damaging effects. Environmental awareness and action has increased, but not enough to stem the destruction of the earth’s resources. In August 2002, over 190 nations and hundreds of representatives from civil society organisations gathered in Johannesburg, South Africa, for the World Summit on Sustainable Development. While there has been disappointment that nations failed to agree global timetables and targets for many issues, the Summit was an important step forward in areas such as the management of toxic chemicals, equitable access to genetic resources and the sharing of their benefits, reducing biodiversity loss, restoring fisheries, improving developing countries’ access to environmentally-sound alternatives to ozone depleting chemicals, and the provision of basic sanitation. It is within this context that UNEP is releasing the latest edition of the report, GEO Latin America and the Caribbean: Environment Outlook 2003. What this latest assessment tells us is that, unlike the global political scene, environmental trends in the region have changed little since 2000. The region’s rich natural resources, especially its forests, continue to be degraded at an alarming rate. At the same time, the environmental problems of cities, where over three quarters of the population live, continue to cause severe health consequences for city dwellers. Policies in the region, includ-

ing those dealing with pollution in cities, have had some success. Nevertheless, the environment is still not fully integrated into economic decision making. Indeed, of the three pillars of sustainable development, it is the economy that is driving development. Social issues such as poverty and inequality and environmental problems such as biodiversity loss and resources contamination have taken a back seat. At Johannesburg we saw a renewed commitment by the countries of Latin America and the Caribbean to confront this situation. The Latin America and the Caribbean Initiative for Sustainable Development approved during the Summit in many ways goes beyond the commitments made in the Johannesburg Plan of Implementation. The initiative signals the seriousness with which the countries of the region are treating their environmental challenges, as well as their commitment as a group to confronting these challenges. The Forum of Ministers of the Environment of Latin America and the Caribbean, through which the Initiative was developed and approved, provides a unique arena in which common problems are discussed and solutions sought. UNEP, as Secretariat of the Forum, is committed to continue providing all the support necessary so as to ensure that the LAC Initiative is implemented and concrete actions initiated in the areas of particular priority for the region. I hope that the GEO Latin America and the Caribbean: Environment Outlook 2003, as well as the many national and sub-regional GEO assessments already developed by UNEP and its partners in the region, form the foundation for informed decision making and inspire the region’s people in their quest for sustainable development.

Introduction

E

fficient environmental management requires a firm basis of up-to-date information on the state of the environment. The methodology used by UNEP to make integrated assessments answers four basic management questions: What is happening to the environment?; Why is it happening?; What is being done about it?, and What will happen if appropriate measures are not taken? The Global Environment Outlook project (GEO), was a response to the requirements of Agenda 21 for reports on the environment and to the UNEP Governing Council’s decision in May 1995 requesting that an in-depth report be prepared on the state of the global environment. An integrated analysis was to be prepared on the state of the environment that would include policy options that could lead to concrete action being taken. The project has also evolved by the efforts made at regional, sub-regional, national and municipal levels, using the same methodology and harmonised conceptual framework (See The Conceptual Framework in this section). This report has been prepared thanks to the participation, of a network of collaborating centres, scientists and politicians concerned with the environment. The project, therefore, provides a global and regional synthesis of existing environmental concerns, trends and policies. The GEO project has two main parts: a) A global cross-sectoral, participatory and consultative environmental assessment process. It incorporates regional views and builds consensus on priority issues and actions through dialogue among policy makers (particularly governments) and scientists at regional and global levels. It also aims to strengthen environmental assessment capacity through training and learning by doing. b) GEO material in printed and electronic formats, including the GEO report series. The series presents periodic reviews of the state of the global environment, trends and emerging issues, together with their social and economic impact. It provides guidance for decision making processes such as the formulation of environmental policies, action planning and resources allocation. The following reports have been published: global (GEO 1997, GEO 2000 and GEO 3); regional (GEO LAC 2000 and 2003); sub-regional (GEO Caribbean and GEO Andes); national (GEO Barbados, Brazil, Chile,

GEO Latin America and the Caribbean - 2003

Costa Rica, Cuba, El Salvador, Nicaragua, Panama and Peru); city assessments (GEO cities Bogota, Buenos Aires, Havana, Manaus, Mexico City, Rio de Janeiro, San Salvador and Santiago); technical reports (tropical forest fires) and GEO for Youth. The coordinated global network of collaborating centres (CCs) is at the core of the GEO process. These centres have played an increasingly active role in preparing GEO reports. They are now responsible for almost all the regional inputs, combining top-down integrated assessment with bottom-up environmental reporting. Other institutions provide specialised expertise, interdisciplinary and on thematic issues. Another essential component of the GEO process in the region is the participation of government environmental policy makers, scientists specialised in environmental questions and representatives of non-governmental organisations. Regional consultations are held and other advisory mechanisms are used to foster and contribute to the ongoing dialogue between them. Consultations help to direct the GEO process, serve to review preliminary material and ensure that each report is useful in formulating policies and planning environmental actions. The report GEO Latin America and the Caribbean: Environment Outlook 2003 is the result of a process undertaken in response to the request by the Forum of Latin American and Caribbean Ministers of the Environment continuously to assess the state of the environment in the region, using the GEO methodology (integrated environmental assessment). For the most difficult challenges, including improving the quality of life and conserving natural resources, this report provides a useful and timely instrument. Population growth is now increasing the demand for food, drinking water, shelter, health, energy, basic services and economic security, while at the same time increasing vulnerability of both natural and urban environments. It is a follow-up to the World Summit on Sustainable Development in Johannesburg (September 2002) and in particular abides by the objectives of the Latin America and the Caribbean Initiative for Sustainable Development (ILAC). The report is an integrated environmental assessment on Latin America and the Caribbean designed to: ·

Update information about the state of the environment.

·

Establish a base to determine environmental priorities.

·

Establish criteria to prepare environmental policies and strategies.

·

Provide a mechanism to assess the efficacy of environmental strategies and policies.

Environment Outlook

Strengthen capacities to evaluate and use the information.

This is the scenario in which the second version of the Latin America and Caribbean Environment Outlook is published. It is the most important report on the state of the environment in Latin America and the Caribbean forming the basis for decisions and action. GEO LAC 2003 contains data, indicators and validated and updated information on better environmental management. It will alert and help countries to better prepare themselves to confront, both nationally and regionally, emerging environmental issues. It contains a general description of the state of the environment in the region, giving an overall view of economic, political, social and environmental aspects. The first chapter, The Environment and Development in Latin America and the Caribbean: Three decades of effort describes the historic process of the environmental theme in the region during the period 1972-2002 (Stockholm to Johannesburg), reviewing important events and debates such as the Brundtland Report and the impact of population growth, economic growth and ecological trends. This chapter will allow the reader to learn about the historic context of the regional environmental debate. The second chapter offers a look at the state of the environment with respect to priority themes for the region: land and food, forest, biodiversity, freshwater, marine and coastal areas, atmosphere, human settlements, health, natural threats and disasters. It reflects the situation by giving concrete national examples and up-to-date information. The third chapter offers a systematic description of environmental policies in the region, focussing on ongoing initiatives and policies, identifying gaps, weaknesses and barriers that prevent policies from being suc-

cessfully implemented. This chapter focuses on planning and environmental policy, on assessing how policies are executed and on legislation. In addition, examples are given that highlight the principal existing strengths, opportunities, weaknesses and dangers in responding to environmental problems. The fourth chapter presents three scenarios - a market scenario, a reforms scenario based on public policies, and a great transitions scenario for the region and seeks to identify environmental and development aspects most sensitive to present-day decisions . For each scenario, relevant factors are described for analysis: the general context, key economic aspects, the situation of technology, society and culture, demography, migrations, governance, and analysis of the effects on natural and urban environments. Finally, conclusions and recommendations formulated by experts involved in the process are presented based on the analysis in the document, enabling readers to join forces against environmental deterioration and helping them to become agents for the promotion of sustainable development. The GEO Latin America and the Caribbean: Environment Outlook 2003 report, like the GEO LAC 2000 report, hopes to heighten awareness about the regional environment so that decisions made are correct, pertinent and relevant. There is still a long way to go but, by uniting the efforts of governments, organizations, institutions and civil society in the region, issues concerning the environment can be brought together to formulate and execute policies and actions to improve the quality of life of everyone living in Latin America and the Caribbean, including those yet to be born, as reflected in the Latin American and Caribbean Initiative for Sustainable Development.

Conceptual framework

© R. Burgos

The conceptual framework used in the GEO project is based on the State-Pressure-Impact-Response (SPIR) methodology. The integrated environmental assessments that use this approach seek to respond to questions not only about the state of the environment, but also about why it is in that state, what we are doing about it and what will happen if the response is not the right one. The SPIR approach begins by depicting the state of the environment; that is, the environmental condition being analyzed: for example, land degradation, water pollution, or the loss of biodiversity. Since its first global report, GEO has used the following topics: · · · · · · · ·

Land Forests Biodiversity Coastal and marine areas Freshwater Urban areas Atmosphere Disasters

In this second regional report in the GEO series a new theme is included for the first time, that of Environment and Human Health. This theme will highlight the existing relations between the situation of the natural world and the human condition in Latin America and the Caribbean. In addition, GEO reports always include an initial section on socio-economic background to profile the

GEO Latin America and the Caribbean - 2003

development features that have such a determining influence on the environment. In this respect, pressure refers to the forces underlying the state and evolution of the environment. Much of this pressure comes from human activities such as those described in the socio-economic background section: the prevalent patterns of production and consumption; population growth; poverty and inequality; and governance mechanisms. However, it is also necessary to consider the pressure resulting from the dynamics of nature itself. These include geological, climate and biological processes that form the basis of human activity, as well as global conditions and waste processing limits. The impact is the effect of the environment – positive or negative, constructive or destructive – on human activity and on whether human beings can continue to subsist or survive as they do in natural surroundings. Principal effects on the population include people’s health, productivity and quality of life. As to truly natural effects, an assessment should be made of the capacity of ecosystems to develop their basic vital functions of providing the population with essential environmental services. The SPIR approach ends the cycle of integrated assessment by considering the human response to three issues: the situation of the environment; the pressure that causes it; and its effects on human activity and natural surroundings. The response to the pressure is strategic, given that only by eliminating the root causes

17 Conceptual framework (continuation) will it be possible to reverse environmental degradation and achieve sustainability. However, it is of great political importance to consider the effects of the present situation of the environment, and the response to them, since this will permit the identification of the core problems that will help mobilize social action in this field. The most important of these effects include those related to human health, so that the theme of Environment and Human Health is of particular relevance in this second regional report. The following responses are of particular interest for the GEO reports: ·

Ratification and implementation of multilateral environmental agreements and non-binding instruments (including multilateral global or regional agreements and action plans). These agreements and instruments are the global framework for environmental action, creating an international regime of opportunities, rights and duties in this field.

·

National environmental legal codes and institutions which form the basis for formulating and implementing policies.

·

Application of economic instruments in environmental policies, within the framework of other, non-environmental, sectoral policies and macroeconomic policies. These instruments are complementary to command and control policies and at times are more effective. However, consideration must be given to the effect –generally negative– of environmental policies implicit in agricultural, industrial or trade policies, as well as in fiscal or monetary macroeconomic policies.

·

Industries and new technologies related to the environment. Production and consumption initiatives, which often have important consequences for the environment.

·

Sources and mechanisms of financing for environmental action, both international (development assistance, direct foreign investment) and national (taxes, payment for environmental services).

·

Public participation in issues concerning the environment, perhaps the principal short-term driver for global and local change.

·

Environmental information that establishes the basis of scientific knowledge behind political decisions and public participation.

·

Environmental training and education, which makes possible medium and long-term transformations in decision makers and the public by building capacities.

For the first time since the beginning of the GEO project, this retrospective report attempts to prepare (as in the global report GEO 3, recently published), an analysis on the state of the environment with a thematic coverage of the whole SPIR cycle. For each theme the second chapter gives an account not only of the respective situations, but also of the main effects and responses during the period of analysis. However, given the role that policies play in helping to reverse environmental deterioration, this regional report presents, as did the first, a chapter specifically devoted to policies. Chapter 3 gives details of the types of responses mentioned above, dealing with many of the most important experiences on the themes of interest following the GEO approach. The thematic analysis used (land, forests, biodiversity, etc.) does not give a precise or specific description of existing relations between the different themes, although this is certainly mentioned when they are relevant either as pressures or effects. The growing expansion of land for agriculture, for example, leads to deforestation and land degradation or loss of natural habitats, with a great deterioration of biodiversity. Soil pollution from the use of agrochemicals has equally serious consequences for biodiversity, quality of continental waters, coastal and marine areas and, finally, the health of the regional population. Loss of biodiversity has negative medium- and long-term effects on sustainability of agriculture and human nutrition. The dynamics of unplanned urbanization and pollution by industry has adverse multiplying effects on the atmosphere, soils, forests, coasts and seas. The complex cause and effect relations fall outside the study’s specific scope, except for the section on Environment and Human Health, which analyses the inter-relationships, as far as quality of human life is concerned. In the rest of the study, however, they are not the focus of this analysis.

From Stockholm to Johannesburg: environment and development in Latin America and the Caribbean

T

he United Nations Conference on the Human En vironment, held in Stockholm in 1972, was the first international conference on the environment that brought together 113 countries and other stakeholders to debate questions of common concern, and it was a turning point in modern thinking on the environment and development. Thirty years later, the Latin America and Caribbean region faces two huge interrelated challenges: how to introduce changes that are both productive and fair, and how to administer natural resources. The first is part of the region’s traditional aspirations and influences its politics. The second has been included more and more in the development agenda (Rosenthal, 1994). At the end of the 1960s, when the environment became an international concern, industrialised countries took the initiative by convening the Stockholm Conference. That may explain why the problem of the environment was initially considered from a rather narrow perspective, as a disease of the rich, a sequel to the economic growth from which they had derived unparalleled levels of wealth and prosperity. Developing countries saw this concern of the rich as a new limitation on their own development. They insisted that the dialogue should include questions related to poverty, underdevelopment, inequality and natural resources, closely and inextricably linked to their own environmental conditions and prospects (Strong, 1994). The Stockholm Conference made a significant contribution to the incorporation of the environment in policies and other public management instruments. Then, only a handful of Latin American and Caribbean representatives were interested in the subject, while today all countries in the region have an environmental institutional and policy base, and citizens’ organisations have multiplied. Over the past 30 years, substantial advances have been made by countries in the region. Environmental themes have been institutionalised, environmental ministries established, natural protected areas set up, environmental rights added to constitutions and a legal apparatus developed. Public opinion has also become in-

·

creasingly well informed and alert. Nevertheless, there is still an awareness that the situation continues to be serious and that much still needs to be done. Concern about the environment has spread: it can be found amongst farmers who seek new ecological alternatives for their crops, as well as amongst entrepreneurs interested in eco-efficient innovations; it is defended in universities and by civil society organisations. No longer regarded as either an issue for rich countries or even a curiosity, the environment has crossed national boundaries and continents and is now the focus of global attention. It has become relevant to the extent that development can no longer be defined without including it. This chapter will review some of the most important aspects of this three-decade history.

Stockholm: growth and population The Stockholm Conference was the first important governmental meeting to concentrate on what was being called the “human environment”. It took place in the context of growing citizen protest and increasing concern in industrialised countries about deterioration of the environment. The conference debate rapidly veered towards the environment’s relations with development, pollution and environmental degradation, the role of poverty and the effects of population growth. Two of these broad themes – the relations between environmental measures and economic growth, and the effects of population growth – had been dealt with a short time earlier in “The Limits to Growth”, a study undertaken for the Club of Rome by a team of researchers (Meadow and others, 1972). This analysis found that there were environmental limits to economic growth, and that if the direction taken during those years were continued, the end result could lead to environmental catastrophe, general famine and population decline. The discussion had become largely bogged down in fixed positions, generating conflict between environmental and economic policies. Several Latin American leaders viewed environmental measures of any kind as impediments to economic progress. This polarisation is possible in any context where material development is taken to mean economic growth. A number of diplomats in Stockholm defended the need to draw up their own environmental policies independently, arguing that the requirements of developed countries – perhaps an unattainable luxury - could not be applied in the region. They went as far as to deny that there was any cause for anxiety about the environment. Concern for economic progress explains the focus on purely economic problems such as international trade

Environment Outlook

terms and the role of relations between states and national sovereignty. Concerned that industrialised countries might start imposing conditions, Latin American and Caribbean countries insisted on maintaining their sovereign right to decide how their natural resources were to be used. Meanwhile “The Limits to Growth” was being discussed in Latin American fora. One example is the Bariloche Foundation’s “World Model”, with distinguished intellectuals declaring that “there are no absolute physical limits in the foreseeable future”, insisting on the abundance of Latin America’s natural resources, emphasising the political aspects of their distribution and renewing their faith in progress (Herrera, 1975). However, going further than raising reasonable doubts arising out of economic policy, there was also a minimalist view that played down environmental aspects and suggested the better use of available technical solutions and ideal state planning. Much attention was also paid in Stockholm to population growth. The warning about a “demographic time bomb” was heard everywhere, and some countries feared that they would be called to account because of their high birth rates (Ehrlich, 1968). Their response, led by the molecular biologist and environmental activist Barry Commoner of the United States, pointed out that over-consumption and social inequality should also be included as principal causes of environmental damage (Commoner, 1971). Thus, the questions connected with consumption of environmental resources and identifying the perpetrators quickly became part of the discussion. Questions kept being raised about the relations between ecology and the economy on the one hand, and environment and consumption, on the other.

impact in various international fora, including the Earth Summit of 1992 (Urquidi, 1994). In the 1970s an intermediate opinion emerged which, although it had no repercussions on its appearance, was to serve almost 10 years later as a basis of the notion of a new “sustainable development economy”. It was called “ecodevelopment” by the French economist Ignacy Sachs. A t the beginning of that decade, he had been one of the first to highlight the reconciliation of development and environmental policies (Urquidi, 1994).

Environmental issues become international In the latter part of the 1970s and at the start of the 1980s, development meant the greater deterioration of natural areas and environmental conditions, and the emergence and strengthening of a wide network of environmental organisations. A sense of commitment appeared in discussions about the environment, especially on flora and fauna conservation. During that decade the debate, which had so far been concentrated on tropical forests, especially in

One positive result of the conference, in addition to a declaration of policy, was the recommendation that a United Nations environmental agency be established. Months later, a UN General Assembly resolution created the United Nations Environment Programme (UNEP) with headquarters in a southern hemisphere country (Kenya) and offices in the different regions. The Latin America and Caribbean (LAC) office was established in Mexico. The debate between environmentalists and economists broadened after 1972. To begin with, Latin American economists took little part in the debate, but later “The Interaction between Styles of Development and the Environment in Latin America” by Chilean economist Osvaldo Sunkel was published as a joint project, running between 1978 and 1989, between the Economic Commission for Latin America and the Caribbean (ECLAC) and UNEP. In November 1979 a regional seminar was held in Santiago, Chile, out of which the Argentinian economist Raúl Prebisch published “Biosphere and Development”. Later, the thinking of these people and other Latin Americans was to have an

Central America and the Amazon, began to broaden in recognition of the global value of national natural resources. Unlike the Stockholm era, other stakeholders as well as governments became involved: multilateral development banks such as the Inter-American Development Bank (IDB) or the World Bank (WB); international and national non-governmental organisations (NGOs); later on, indigenous organisations such as the Co-ordinator of Indigenous Organizations of the Amazon Basin (COICA) also joined in. During the 1970s, more than one country defended the development of the Amazon “at any price” model. The creation of the Treaty for Amazon Cooperation in 1978 was a palliative that placed conditions on the role that NGOs and indigenous groups could play. The possibility of broadening the discussion was limited by authoritarian regimes in several southern cone countries and by political and military instability in Central America. For almost 20 years UNEP stressed the economic advantages of environmental protection and the costs of damage to natural resources. This resulted in: cleaning up the Baltic Sea and part of the Mediterranean; the Montreal Protocol of 1987 to reduce, and eventually ban, the production and use of chlorofluorocarbons (CFCs); the Basel Convention of 1989 on the Control of Transboundary Movements of Hazardous Wastes; the initiation of negotiations on global climate change, and several other specific and regional agreements and action plans (see the section on Atmosphere in Chapter 2). In 1982 the Forum of Ministers of the Environment of Latin America and the Caribbean was created. The Forum is the longest standing, most representative and important political gathering for reaching agreement on environmental policies and responses on a regional scale. All the countries of the region are members. The Regional Office for Latin America and the Caribbean of the United Nations Environment Programme (UNEP/ ROLAC) acts as the Secretariat. Since 1982 there have been fourteen meetings of the Forum in different cities of the region, helping to orient environmental activities and ensure that regional and international cooperation is more and more efficient and coherent and better targets the priorities identified by the ministers. Conservation organisations flourished, promoting their interests in protecting important ecosystems or endangered species. They quickly understood that the basic causes of such problems were to be found in development strategies, especially in economic practices. Promoted by the World Conservation Union (IUCN) with the support of UNEP and the World Wide Fund for Nature (WWF), the first World Conservation Strategy was drafted in 1980 (IUCN, UNEP and WWF, 1980). This was a key document that recognised the importance of economics and development, and linked them in an

environmental strategy. Its proposals place emphasis on satisfying human needs (present and future) and the quality of life rather than simply pushing economic growth; this endorsed the doubts that had been cast during that era. For many years this was the reference document of the principal environmental agencies in Latin America and the Caribbean, and provided one of the first modern definitions of development as “sustainable”, with a new look on ecological limits.

In terms of better environmental awareness a number of events stand out: the denunciations regarding the burning of the Amazon forest in newspapers within and outside of the region, the impact of the trials of the Kayapo Indians in Brazil, and the assassination of the Brazilian leader Chico Mendes in 1998 (Gross, 1989). Strong international pressure included declarations by several European presidents to proclaim the Amazon as “humanity’s heritage”. Once again, several governments reacted by claiming autonomy and asked that the subject of the environment be included in the assistance provided by developed countries. In some countries, pressure from outside the region also had a strong impact on reformulating policies. Loans by multilateral development banks began to have environmental strings attached. From the middle of the 1990s, both the IDB and the WB introduced programmes on “institutional strengthening” of the environment. In other cases, this reformulation was associated with the economic integration process in the region. For example, changes were made to Mexico’s environmental administration as a result of the negotiations of the Free Trade Agreement with the United States and Canada (between 1990 and 1992).

Environment Outlook

“Our Common Future” and “Our Own Agenda” The political side developed during the mid-1980s in tandem with the establishment by the United Nations Secretary General in 1983 of a World Commission on Environment and Development. With Gro Harlem Brundtland of Norway as president, this body had 23 members (including four from Latin America). “Our Common Future”, the Commission’s report, suggested possible economic growth based on policies of sustainability and expanding the environmental resources base. The hope it expressed for a better future was, however, conditional as it depended on resolute political action permitting proper administration of environmental resources for sustainable human progress and also the survival of the human species. The Commission observed that many “development” examples were leading to increased poverty, vulnerability and even degradation of the environment. This demonstrated the pressing need for a new concept of development that would protect future human progress: “Sustainable development” was defined as “development that satisfies the present needs of people without compromising the capacity of future generations to satisfy their needs” (CMMAD, 1987). It recognises as the warning given by the Club of Rome that the biosphere had a limited capacity to absorb environmental impacts, but that other restraints it was calling for depended essentially on human beings, and therefore could be modified by social organisation and technology. The contradiction between conservation and economic growth, becoming apparent after the Stockholm Conference, was reinterpreted. The ecological framework, that had earlier been regarded as an insuperable obstacle to growth, then became essential to ensure it. The idea of conservation as a condition for growth had already been met in discussions in several contemporary fora. In 1987, for example, a document issued by the WB and the International Monetary Fund joint development committee had pointed out that economic growth was complementary to environmental conservation and the eradication of poverty (DC, 1987). Along these same lines emerged “Our Own Agenda” (1990), an initiative for Latin America and the Caribbean promoted by the IDB and the United Nations Development Programme (UNDP) as a “Development and Environmental Commission for Latin America and the Caribbean” (CDMAALC, 1990). This proposal for the most part repeated the concepts of “Our Common Future”, placing emphasis on the fair distribution of the social benefits of natural resources. It is thought that the

23

limited effect of this agenda was due to the lack of backing by civil organisations of the work of the editing committee set up by the initiative’s organisers, hence its proposals had little effect on the preparation of the Earth Summit in Rio de Janeiro in 1992.

The Earth Summit process In response to the Brundtland Commission, in December 1989 the United Nations General Assembly convened a Conference on the Environment and Development destined to be held in June 1992. It was decided that countries would be represented by their heads of state or of government at this event, that later became known as the first “Earth Summit”. Resolution 44/ 228 made it clear that this would be a conference on “the environment and development” with the subjects integrated in every aspect from climate change to human settlements. It was hoped that a series of concrete measures would emerge from the conference, including the following (Strong, 1994): ●

An “Earth Charter” or declaration of basic principles to serve countries and individuals as a guide of conduct concerning the environment and development, ensuring a future for the Earth as a hospitable home for human beings and other forms of life.

●

An action agenda - “Agenda 21” - to establish the work programme agreed upon by the international community for the post-1992 period and the 21st century, with reference to subjects dealt with at the conference, together with setting priorities and goals, estimating costs, designing methods and assigning responsibilities.

●

The means of putting this agenda into practice, including: - financial resources, - transfer of technology, - strengthening institutional capacities and processes.

It took several years to prepare for the Earth Summit by mobilising governments, especially non-governmental organisations. During the preparatory phase, and at the Summit itself, the conviction emerged that the success of the conference would be judged not by what happened in June 1992, but by what would be achieved in the following years (Montaño, 1994). It proved impossible to separate documents endorsed by governments at the Earth Summit from other proposals presented in the process of the preparation of the Summit. Amongst the most important was the IUCN’s second World Conservation Strategy, prepared jointly with UNEP and WWF (1991), called “Caring for the Earth”. This defined sustainable development as improv-

ing the “quality of human life without exhausting the capacity of ecosystems that sustain it”. The report added that a “sustainable economy” was the product of this type of development where it was possible to maintain the basis of natural resources and “may continue developing by means of adaptation and improved knowledge, organisation and technical efficiency, and greater understanding”. This strategy made it clear that profound cultural changes would be needed, and proposed nine principles for a “sustainable society”: respecting and caring for the community of living beings; improving the quality of human life; conserving biodiversity; reducing to a minimum the exhaustion of non-renewable resources; keeping within the Earth’s capacity; modifying personal attitudes and practices; empowering communities to care for their own environments; providing a national framework to integrate development and conservation; and building a world alliance. These contributions expanded the environmental agenda beyond just concern for endangered species and landscapes, to a wider outlook on the concept of using biodiversity (which ranges from genetic resources to ecosystems), relations with development strategies, the institutional base, and science and technology. At the same time, civil organisations and environmental groups were promoting their own ideas in different fora. An example is the “Ya Wananchi” Agenda approved at the international meeting on “Roots of the Future” (Paris, December 1991) (Ya Wananchi, 1991). This issued a warning that the essential question was not conservation of the environment itself, but rather how to administer natural resources to achieve the most effective social, economic and physical sustainable development. In Latin America and the Caribbean declarations and contributions were made like those of “Las Vertientes”·(Chile) and “Las Leñas” (Argentina). One outstanding aspect of the NGO participation at the Earth Summit was the generation of “alternative agreements”, with their own contributions and vision of the subjects under discussion (FIONGsMS, 1993). These offered a range of approaches, depth of analysis and suggestions for preparing proposals. ·

Latin American and Caribbean governments and organisations insisted on maintaining the close relationship between the region’s poverty and environmental circumstances, which often gave rise to problems. The meeting of environment ministers called by UNEP in 1990 concluded that “there is an indissoluble link between environmental deterioration and poverty” since both are interacting effects of the same world process of defective growth. “Improving economic and social conditions”, said the environment ministers on this occasion, “will be the essential factor in halting environmental degradation in the region” (UNEP/ROLAC, 1990). In 1992, the Rio Earth Summit marked a turning point by producing agreements that attempted to treat global environmental subjects more comprehensively by including sustainable development as a main goal. At the beginning of the 1990s, the five Earth Summit agreements provided the most universal political and articulated response to the problem of how to establish an international co-operation regime designed to achieve full inclusion of the environment into development. They are:, ●

The Rio Declaration on the Environment and Development;

●

Agenda 21;

●

The Declaration on principles relating to forests;

●

The United Nations Framework Convention on Climate Change, and

●

The Convention on Biological Diversity.

The Rio Declaration was the cornerstone of the concept of sustainable development. For the first time, principles were introduced and accepted by all participants that serve to build new relations among countries and encourage economic, social and environmental balance between developed and developing countries. The following principles are especially important:

Chapter 1: From Stockholm to Johannesburg: Environment and Development in Latin America and the Caribbean

Environment Outlook

●

Principle 7: States shall co-operate in a spirit of global partnership to conserve, protect and restore the health and integrity of the Earth’s ecosystem. In view of the different contributions to global environmental degradation, States have common but differentiated responsibilities. The developed countries acknowledge the responsibility they bear in the international pursuit for sustainable development in view of the pressures their societies place on the global environment and of the technologies and financial resources they command.

●

Principle 8: To achieve sustainable development and a higher quality of life for all people, States should reduce and eliminate unsustainable patterns of production and consumption and promote appropriate demographic policies.

●

Principle 9: States should cooperate to strengthen endogenous capacity-building for sustainable development by improving scientific understanding by exchanges of scientific and technological knowledge, and by enhancing the development, adaptation, diffusion and transfer of technologies, including new and innovative technologies.

●

Principle 10: Environmental issues are best handled with participation of all concerned citizens, at the relevant level. At the national level, each individual shall have appropriate access to information concerning the environment that is held by public authorities, including information on hazardous materials and activities in their communities, and the opportunity to participate in decision-making processes. States shall facilitate and encourage public awareness and participation by making information widely available. Effective access to judicial and administrative proceedings, including redress and remedy, shall be provided.

●

Principle 11: States shall enact effective environmental legislation. Environmental standards, management objectives and priorities should reflect the environmental and development context to which they apply. Standards applied by some countries may be inappropriate and of unwarranted economic and social cost to other countries in particular developing countries.

●

·

Principle 15: In order to protect the environment, the precautionary approach shall be widely applied by States according to their capabilities. Where there are threats of serious or irreversible damage, lack of full scientific certainty shall not be used as a reason for posting cost-effective measures to prevent environmental degradation. Principle 16: National authorities should endeavour to promote the internalization of environmental costs and the use of economic instruments, taking into account the approach that the polluter should, in prin-

25

ciple, bear the cost of pollution, with due regard to the public interest and without distorting international trade and investment. The results of the Earth Summit are still being felt today. The Commission on Sustainable Development, with a copious agenda, was constituted within the framework of the United Nations. The different international agreements are still in force and have resulted in specific protocols (such as the Cartagena Protocol on Biosafety, and the Kyoto Protocol of the United Nations Framework Convention on Climate Change). Agenda 21 has been diversified, especially regarding local initiatives. With the conference as a starting point, other regional initiatives have been developed, such as the Central American Alliance for Sustainable Development (1994), the Summit of the Americas on Sustainable Development (Santa Cruz de la Sierra, Bolivia, 1996) and the commitments of the Andean Community to protect its biodiversity. The Action Programme for Sustainable Development in Small Island Developing States in the Caribbean deserves a special mention. The particular situation of the world’s small island states became obvious, both during the preparations and at the Earth Summit. This prompted the United Nations to call a special conference on how to make sustainable development feasible in those countries. As a result, the United Nations World Conference on Sustainable Development in Small Island Developing States was held in 1994. It issued the Declaration of Barbados and the Programme of Action, adopted by 111 participating governments, proposing principles and development strategies designed to protect the fragile environment in small insular developing states (ECLAC-UNEP, 2001b).

New economic conditions: 1990-2002 The debt crisis brought about political and economic changes in Latin America and the Caribbean. It also led to new conditions which, during the 1990s, had a great affect on the administration of the environment. These included liberalisation of foreign trade, reduction of state regulations, privatisation of public companies and services, liberalisation of financial markets, more flexible labour relations and contracts, and also the extension of property rights into new areas. In consequence, patterns of foreign trade and exports have been modified, leaving a number of national industrial sectors unprotected and increasing the export of raw materials. Markets were opened, countries began to import more goods at lower prices, and their consumption patterns converted to reflect short-life material goods that quickly became obsolete, and with more non-biodegradable components.

Latin America and the Caribbean

Agricultural industries expanded with redevelopment that promoted the export of crops, in large measure those for livestock feed (sorghum, rice, soya beans), and in other cases those for specific consumption niches in developed countries (fruit from Central America and Chile, flowers from Colombia). This led to the expansion of agriculture into wildlife areas and to pollution of soils and water. Efforts were made to increase exports to the maximum and to lower costs; environmental controls were seen as impediments. While the importance of conservation was highlighted in Stockholm and at the Earth Summit, agriculture has always remained a subject for debate. Environmental regulation has been associated with restrictions on food self-sufficiency. This was made worse by the reduction of state functions and the weakening of sectoral development planning. A great deal of agricultural management is subject to market conditions, making it hard to include controls and environmental improvements (Escudero, 1998).

Laws and institutions States in Latin America and the Caribbean have given different responses to the subject of the environment. In the first place, they have included it in their programmed goals. Secondly, they have expanded their coverage by using policy measures to regulate approaches to and management of the environment. It was only after the Earth Summit that consideration of the environment as a subject was accepted not only by governments but also by other stakeholders such as business leaders. Since that time the discussion has centred on how to harmonise environmental protection with economic development, and how to resolve conflicts. Taking as a focal point the preparation of general rules, nation states specify the subjects for inclusion and the methods for discussing them. This has led to different environmental laws being passed, both in general (for example, environmental codes, or on the assessment of the environmental impact) and specific laws (laws on water or forests). However, fewer advances have been made in making environmental management and participation more democratically accessible. Mention may also be made of the general trend towards institutionalising aspects which were considered earlier to be almost exclusively the province of private political action by environmentalists. This process is reinforced by external demands (industrialised countries, multilateral development banks, co-operation agencies), and by national pressure (the environmental movement itself, the press). Participating stakeholders have many different objectives and adopt different positions. Interactions between new and old policies, as well as the impulse of the Stockholm Conference and espe·

cially of the Earth Summit, have released a torrent of new legal and institutional environmental frameworks. These reflect the sustainable development concerns of society in Latin America and the Caribbean. This is perhaps one of the most concrete consequences perceptible at state level over the past 30 years (Brañes, 2001). The recent complex political history of most of these countries has brought about an institutional renovation that is reflected in constitutional changes. Between 1972 and 1999 the following new political constitutions incorporating the environment have been drafted: in Panama (1972); Cuba (1976); Peru (1979 and 1993); and Ecuador (1979 and 1998), amongst others. The Constitution of Panama (1972) was the first to indicate that the state should protect the environment and that of Cuba (1976) substituted the word “state” for “society” (Brañes, 2001). The “first wave” of legal and institutional reforms is associated with the influence of the Stockholm Conference; laws on environmental impact and general laws on the environment were promulgated, and the first governmental agencies on the environment were established. Colombia was the regional pioneer with a highlevel institutionalisation of the environment (National Code on Renewable and Protected Natural Resources, 1974). Later, Venezuela passed a decree on Organic Law on the Environment (1976) which led to the creation of the Ministry of the Environment and Renewable Natural Resources, an example followed by Ecuador, Cuba, Brazil, Guatemala, Mexico, Peru and Bolivia. The content of these laws is similar: national environmental policy, legal instruments to apply it and protection of certain natural resources (Brañes, 2001). In the English-speaking Caribbean, laws and policies to protect the environment came along later. The initial efforts were devoted to establishing ministerial responsibilities. After the Earth Summit, attempts were made to conclude regional agreements. The first comprehensive attempt was the National Conservation and Environmental Protection Act in Saint Kitts and Nevis (1987), followed by the Natural Resources Conservation Act in Jamaica (1991). Afterwards, laws of this type were established in Belize, Trinidad and Tobago, Saint Lucia and Guyana (UNEP, 2002). On a regional scale, there was a second wave” of reforms associated with the Earth Summit, expanding legislation and creating ministries of the environment. Until nearly 1990, only one such ministry existed in the region, the Ministry of the Environment and Renewable Natural Resources of Venezuela, created in 1976. In general, the environmental component used to be a dependency of an existing ministry or secretariat (Brañes, 2001). After the 1992 Summit, however, innovations were proposed such as the establishment in Bolivia of the Ministry of Sustainable Development (including environmental administration with economic planning), a national comptroller’s office for the environment, and

Environment Outlook

biodiversity, forestry and mining superintendents (with the exceptional attribute of being under parliamentary control). In addition, countries in the region have increasingly been ratifying or approving international treaties, conventions or agreements dedicated to the environment (Morán, 1996). This trend has been accompanied – and, to a great extent, counterbalanced – by extensive structural reforms in the 1990s that reduced the state’s presence in several countries. The effect was to transfer part of the administration to private stakeholders, and in some cases to fragment or reduce the size of secretariats or ministries (Acuña, 2000). There are still problems about applying legislation and how to relate it to other policies, especially economic (Brañes, 2001). In general, difficulties persist in the introduction of the environmental dimension at a high level in development strategies. For example, one recent IDB assessment warned that the mechanisms of environmental assessment “are not concretely incorporated”, limiting the possibility of exerting a high-level influence (Espinoza and Alzina, 2001). Much has been accomplished in the last three decades. Nevertheless, concern about the environment is growing. Numerous environmental authorities such as secretariats and ministries have been established and environmental policies have been developed and strengthened through institutional change and legislation. Most Latin American and the Caribbean countries have included the environment in their constitutions and different environmental laws enacted have resulted in progress. The number of international and regional environmental agreements has grown over the past 30 years, bringing greater awareness of the environment and better decision-making. Groups of citizens and nongovernmental organisations in the region now play a more important role in development and conservation activities that concern the environment. This is done with timely participation and based on open and transparent information, even if these steps have not been able to reverse the trends of poverty growth and environmental degradation.

Nature and the Market While the economy-ecology discussion has been going on for years, at the end of the 1980s a price began to be placed on nature, and ways were sought to introduce the environment into the market as yet another commodity. These ideas had already been mentioned in the Earth Summit declarations, but the most important regional step was taken by combining the ideas in Changing Productive Patterns with Social Equity by ECLAC with outside influences (ECLAC, 1990: Anderson, 1992, Baden and Stroup, 1992). The problem was how to assign the concept of capital to nature and thus change conservation into a type of investment; a price would be put on nature and it

27

would be given property rights. Ideas of this kind abound in proposals made during the past ten years by the WB, the IDB and other international agencies, and have been taken up by different regional institutions. This was an advance compared to the previous situation, where nature was ignored in economic terms. In many cases the economic cost of pollution or soil degradation had become evident; in others, encouragement was given to defending natural areas for their potential economic value. Attempts were made to introduce national corrections into environmental accounts by using environmental indicators, or by means of satellite accounts that included environmental assessments (Gligo, 1990). It was also important to identify legitimate competition by seeking the highest environmental quality to improve international trade (CEPAL, 1991). However, tensions also became evident. In some cases the whole of nature has been reduced to an expression of natural capital and environmental policy confined to technical questions, usually associated with determining the true price of natural resources and naming their owners. This is no easy task; some people assign a high value to wildlife while to others it is of little value. The situation is made even more difficult when conservation efforts bring no evident economic yields or, on the contrary, when exploitation turns out to be a profitable business (Leff, 1994). This problem has had a major influence on discussions of sustainable development. The trend on economic assessment inclines towards the so-called “weak sustainability” currents. Another trend which, rather than go against the first one, overtakes it, accepts economic assessment as one of several factors. “Super strong” sustainability brings back the plurality of values (economic or otherwise), accepting that open debate is needed if better results are to be achieved.

Ten years after the Earth Summit and future outlook In October 2001the Latin America and Caribbean regional preparatory conference devised an action plan that was presented to the Commission on Sustainable Development. As a leitmotif for the Johannesburg Summit in 2002, the countries put forward ideas for an equitable, inclusive and sustainable new globalisation, pointing out the need for “greater coherence and coordination between environmental, social and economic strategies and policies” (ECLAC-UNEP, 2001a). The thousands of participants at Johannesburg included heads of state and of government, national delegates, and leaders of non-governmental organisations, business and other main groups. Attention was centred on challenges such as improving the quality of life and conservation in a world of constantly increasing population, augmenting the demand for food, water,

housing, energy, sanitation services and economic security.

●

Kyoto Protocol: when Russia ratified the Protocol there were enough signatures for it to enter into force.

At the extraordinary meeting of the Forum of Ministers of the Environment of Latin America and the Caribbean, held within the framework of the Johannesburg Summit, the Latin America and Caribbean Initiative for Sustainable Development (ILAC) was approved and included in the Summit’s implementation plan. Its objectives are to:

●

Natural resources: losses in seas and forests should be halted, “as soon as possible”

●

Sanitary installations: by 2015, the number of people without running water or access to sanitary services should be reduced by half.

●

Energy: it was agreed to increase renewable energy sources; however, neither goals nor timetables were set.

●

Increase the use of renewable energy sources until 10 % of the regional energy requirements are met.

●

Increase natural protected areas and forest lands.

●

Improve management of watersheds and marine and coastal zones, and reduce the discharge of pollutants.

●

Adopt regulatory frameworks for access to genetic resources, according to the fair distribution of benefits principle.

●

Reduce emissions into the air and increase coverage of drinking water services and sewage treatment.

●

Implement plans and policies to reduce urban environmental vulnerability in the face of anthropogenic disasters and those caused by natural phenomena, including the formulation of a regional early warning system.

●

Implement the Kyoto Protocol.

●

Develop technologies to ensure the quality and proper management of water.

●

Advance in areas such as health, the eradication of poverty and equity and sustainability of production and consumption patterns.

The Declaration of Johannesburg reaffirms the determination to work in the name of sustainable development. Furthermore, a Plan of Implementation was agreed with recommendations and objectives to reconcile economic growth, social justice and protection of the environment. Among the actions and goals established the following are of special interest: ●

·

Biodiversity: by 2010 there should be a “significant reduction” in the current rate of loss of animal and plant species.

●

Chemical products: by 2020 the significant adverse effects of chemical substances on human beings and nature should be minimised.

●

Fishery: there should be no excessive harvesting of fishery resources. By 2015 one of the goals is to restore damaged fish stocks.

●

Trade and globalisation subsidies that harm the environment should be eliminated.

The Declaration also left loose ends. The Plan of Implementation did not include a timetable to end rich countries’ agricultural subsidies or to end the crisis in international prices of basic products. The Plan urged all countries to “substantially increase” the use of renewable energy, but did not stipulate specific percentages or time limits to comply. Three decades after the Stockholm Conference, it is clear that environmental problems are problems arising out of development in a manner unfair to human societies and harming natural systems. The developed world bears the greater responsibility. It will be impossible to achieve environmentally and socially sustainable development if countries are not disposed to change their present growth patterns and how they use their natural patrimonies (Guimaraes and Bárcena, 2001). In seeking solutions to environmental problems on world and regional scales, and in the face of pressing needs of sustainable development, the efforts of countries in the region should be directed towards implementing ILAC by: setting action priorities to promote development by establishing models that put an end to poverty, inequity and environmental deterioration; improve environmental education in all its economic and social aspects; introduce sustainable energy use and increase the use of renewable energy sources; manage protected areas for sustainable use of biodiversity; adapt to the effects of climate change and sustainable management in urban and rural areas, with special emphasis on actions concerning health, environmental sanitation and minimizing vulnerability risks from natural disasters (UNEP/ROLAC, 2002). Amongst the changes proposed to the economic plan is a productive restoration that satisfies the three criteria of increasing competition, reducing social inequalities and stopping environmental deterioration associated with current specialisation in production. As for the social plan, a way must be found to cut the Gordian knot created by the deep socio-economic inequalities by which large majorities in the region are bound. (Guimaraes and Bárcena, 2001).

Latin America and the Caribbean

State of the Environment in Latin America and the Caribbean, 1972-2002 Introduction This chapter presents a retrospective view of how the environment in the region has evolved over the past three decades, in the interval between the United Nations Conference on the Human Environment, held in Stockholm (Sweden) in 1972, and the World Summit on Sustainable Development, held in Johannesburg (South Africa), in 2002. In the 30 years under review, the state of the environment in Latin America and the Caribbean has reflected the ideas and policies that have prevailed in the region since 1972. As we shall see in this and the following chapters, the environment has come to occupy an important, although still secondary, place on the regional political agenda. Significant state regulations are being established and expanded in this field, and unprecedented action is being taken by the private sector and civil society. However, it is also clear that economic development has been the primary objective , in many cases at the expense of the environment. This situation is a confirmation of the opinions expressed by many of the region’s governments in Stockholm in 1972. As pointed out in Chapter One, at that time the regional mindset was reactive, and placed the demands of development – understood basically as economic growth – above the need to protect the environmental foundation of this development.

·

Thirty years later, there is more awareness about how development involves the environment, but it has not been possible to put a stop to the deterioration of indispensable environmental goods and services. If in 1972 the Stockholm Conference was inaugurated with participants willing to identify and respect environmental limits to growth, today there is a different reality facing Latin America and the Caribbean: the economy has not shown steady growth, there is more poverty and less security, and environmental deterioration has worsened. This chapter highlights the growing exploitation of natural resources, particularly by deforestation, loss of biodiversity and degradation, and pollution of soils and water (both on land and in coastal and marine zones). The place of exports at the top of the agenda has been accompanied by a widening of the income gap in much of the region. This, together with a high rate of urbanisation, has intensified the trend towards adopting lifestyles and consumption patterns that have a high environmental and sanitary impact, and this is reflected in the urban pollution (water, air) indices and the new disease and mortality characteristics in the region. Enormous damages have been caused by the vulnerability of the natural and urban environment, and an increase in natural disasters in the countries in the region.

Socio-economic trends

A

lthough democracy has advanced in many countries in Latin America and the Caribbean, it is an unstable political process. The fluctuating or downward trend of economic indicators over the past 20 years shows not only in the lost decade of the 1980s, but also over the most recent five-year period over 19982002- the lost half-decade. In this context, poverty, social inequality and environmental deterioration continue to be the main obstacles in the way of the region’s sustainable development.

Economy In the period 1972-2002, regional economic growth rates — in terms of gross domestic product (GDP) — dropped from an annual average above 5.6 per cent in 1971-1980 to only 1.2 per cent in 1981-1990 (the socalled lost decade) and to 3.3 per cent in 1991-2000 (ECLAC and UNEP, 2001). Since 1980, growth rates have been lower than the annual average of 5.5 per cent for the period from 1945-1980, and are well below the annual average of –six to seven per cent that ECLAC believes is necessary to overcome the region’s serious poverty problems (CEPAL, 2000a). In spite of the relative growth of GDP in the 1990s, in 2001-2002 growth rates were even lower than in the 1980s (0.3 and 0.5 per cent, respectively). Average regional GDP growth rate per capita in the period 19982002 was 0.3 per cent and in 2002 it was two per cent lower than in 1997, which explains the talk of a “lost half decade” (CEPAL, 2002a, 2002c).

33

this strategic natural resource. As a result, regional average growth rate plunged from 8.4 per cent in 1973 to 2.2 in 1983 (World Bank, 2001). During the 1990s, countries in the region introduced economic reforms based on being more open to foreign trade and on liberalising national financial markets and foreign capital flows. Private initiative also played a role in producing goods and services, and in providing public services and social benefits. There was a significant decrease in inflation and the public sector deficit was kept under control. However, the impoverishment of the previous decade (income per capita in the 1980s fell to an annual rate of almost one per cent) was only just reversed in the 1990s with an average increase of two per cent per year in the rate of income per capita (Rodrik, 2001). Foreign debt continues to be high and is a serious impediment to development. There was a 21-fold increase in the foreign debt balance between 1971 and 1999 from US$46,300 to US$982,000 million, representing 38 per cent of total world foreign debt (World Bank, 2001). Accumulated foreign debt had reached about US$726,000 million by the end of 2001 (CEPAL, 2001b), and servicing it cost more than 45 per cent of income earned from exports of goods and services (IMF, 2001). Several countries suffered from hyperinflation - Argentina and Brazil in particular - as governments sought to finance the deficit by printing money. In the 1990s, severe macroeconomic imbalances carried over from the previous decade caused crises in Mexico (1995) and Brazil (1998) (ECLAC and UNEP, 2001), and more recently in Argentina (2001-2002). Argentina alone has a foreign debt of US$147,900 million. This represents about 18 per cent of the region’s total debt. Some highly indebted poor countries, such as Bolivia and Guyana, recently obtained the classification needed to allow them to reduce their debt to sustainable levels (World Bank, 2001).

It is important to point out that poverty in the region has kept close pace with these GDP figures (see Social situation in this section). In effect, while poverty was reduced between 1960 and 1980, it again increased during the 1980s until reaching a level in 1990 very similar to that recorded 30 years earlier (UNEP, 2000; CEPAL, 2002a). And, while it then dropped once more, it seems to have stagnated after 1997, showing an upward trend recently (CEPAL, 2002a).

In general, economic growth in the 1990s was volatile and reflected a pattern of increased dependence on foreign financing. In the first half of the decade, net transfer of resources to the region brought a boom in economic activity but at a cost of accumulating macroeconomic imbalances reflected in the region’s greater vulnerability to being affected by foreign financial crises (ECLAC and UNEP, 2001).

Since the middle of the 1970s, debt, macroeconomic imbalances and unfavourable terms of trade have blocked GDP growth in most countries in the region, seriously restricting possibilities for social development. The rise in petroleum prices in the 1970s – although certainly promoting growth in crude oil exporting countries (Mexico, Trinidad and Tobago and Venezuela) – made matters worse in countries that have to import

Direct foreign investments showed a notable growth during the 1990s, to reach a total of US$77,300 million in 1999 (ECLAC, 2001b). This was largely associated with the boom in asset privatisations. The world recession has caused these flows to lessen, especially in recent years. Estimates show that half the foreign investments in the 1990s were destined for the purchase of already-existing assets, and did not create new produc-

tive capacities; furthermore, this process strengthened the strategic position of transnational companies (ECLAC and UNEP, 2001). After a significant upturn in the period 1992-1995, the growth of regional exports suffered a progressive reduction until it became negative in 1998. The upswing in 2000 did not last, and exports fell back to negative rates in 2001 and 2002 (CEPAL, 2002b). The region’s share of world exports continues to be low, and is still under six per cent (ECLAC and UNEP, 2001). The boom in manufacturing exports in countries like Mexico, Central America and several in the Caribbean has largely been associated with the proliferation of assembly activities (maquilas), with little integration into national economies. International trade recently began to reflect integration processes, including free trade agreements and customs unions. Exports from the Andean Community countries grew by 37 per cent during 2000, while their intra-regional exports increased by 29 per cent. Similarly, in MERCOSUR intra-regional trade increased by 21 per cent and, for member countries of the North American Free Trade Agreement, by 20 per cent (BID, 2000). More recently, trade within MERCOSUR has contracted due to the effects of the crises in Brazil (1999) and in Argentina (2001-2002). Nevertheless, on the initiative of the United States, negotiations continue on the Free Trade Area for the Americas (FTAA) programmed to enter into force in 2005.

Energy Key factors in long-term regional economic development are the supply and consumption patterns of energy. Latin America and the Caribbean have 11 per cent of world petroleum reserves, six per cent of natural gas, 1.6 per cent of coal, 22 per cent of hydropower potential and 14 per cent of installed geothermic capacity (ECLAC and UNEP, 2001). However, a large part of this wealth is under-used, or used inefficiently. An example is that, while only 15 per cent of regional hydropower potential is used, energy consumption per unit of output has increased in recent years. The regional share of world petroleum reserves - the strategic energy input in most countries - doubled over the past 20 years; Mexico and Venezuela have 40 and 50 per cent, respectively, of the total. Regional natural gas reserves grew still more (3.5 times in the period), again in Venezuela and México (with 51 and 28 per cent, respectively); nevertheless, their share of the world total grew by just one per cent because of increased reserves in the Middle East and the former Soviet Union. Regional coal reserves are mainly in Brazil and Colombia, who have 80 per cent of the total.

With some exceptions (Mexico, for example) most exports continue to be of raw materials, especially petroleum and its derivatives, minerals and agricultural and forestry products. Towards the end of the 1990s, more than 40 per cent of regional exports were primary products or manufactured goods that required intensive use of natural resources (CEPAL, 2001b). Between 1980 and 1995, the volume of regional exports using polluting production processes tripled (ECLAC and UNEP, 2001). As a result, and since these activities are unsustainable over the long term, there was an increase in vulnerability and external dependence (because of limited access to markets and raw materials UNEP, 2000). Demands by international consumers have made the industrial sector, move towards improving the environmental quality of production, although the process is slower in the small and medium-sized companies sector (ECLAC and UNEP, 2001). In several countries national industry has declined in importance (for example in Peru, Argentina and Chile), and imports continue to grow faster than exports (ECLAC and UNEP, 2001). In the services sector, the tourism industry’s growth places great pressure on the environment, particularly in the Caribbean, although increased ecotourism can help to cushion this impact (ECLAC and UNEP, 2001).

Latin America and the Caribbean

Although the region has large energy supplies, consumption per capita (equal to 9.4 barrels of petroleum per year) is 20 per cent below the world average (ECLAC and UNEP, 2001). In addition, while regional consumption has been constantly growing over the past 20 years, its share of world consumption (5.2 percent of the total) has not changed significantly. It is also notable that productive efficiency (measured in terms of energy consumption per unit of output) has stagnated or even deteriorated in these two decades (ECLAC and UNEP, 2001). While industrialised countries’ energy intensity fell by 20 per cent between 1980 and 1999, at the end of that period Latin America and the Caribbean consumed seven per cent more energy with no increase in production. The failure to use better technologies, an obsolete industry, subsidised fuel prices (with respect to international market prices) and the automotive industry’s high and inefficient consumption are all explanations for regional energy intensity. The trend towards its increase– a consequence of industry repositioning towards productive processes and exports with high consumption of energy – has been notable in countries such as Brazil. This contrasts with the region’s considerable total supply of energy as a percentage of the gross domestic product, which is 40 per cent higher than that in industrialised countries (ECLAC and UNEP, 2001). This reveals a serious problem of underutilisation of energy and is one of the sustainable development challenges facing the region.

Social situation It has been estimated that in 2003 the number of people living in poverty in Latin America and the Caribbean was 225 million or 43.9 per cent of the total population, and of these 100 million (19.4 per cent) lived in extreme poverty (CEPAL, 2003). There was a considerable reduction of poverty levels between 1960 and 1980 - from 51 to 40.5 per cent of the population (an estimated total of 135.9 million people). During the lost decade of the 1980s the percentage of poor people again increased until it reached the 1960 level of 48.3 per cent of the total population in 1990. While the percentage of poor people in 1960 and 1990 was similar, even more people, 200.2 million, were considered poor in 1990 then in 1960 (UNEP, 2000; CEPAL, 2002a, 2003). This figure fell to 43.5 per cent in 1997 and has remained constant since. The absolute number of poor has increased by close to 66% since 1980 (CEPAL, 2002a, 2003). Latin America and the Caribbean is the region with the world’s biggest income inequality (ECLAC, 2001a). In the global context, a notable feature is the large concentration of national income in the wealthiest 10 per cent of the population: in all cases, this sector received more than 30 per cent of total income (35 per cent in ·

most countries but reaching 45 per cent in Brazil). The poorest 40 per cent of the population does not receive more than 15 per cent of income. During the 1990s (in 13 of the 20 regional countries for which information is available), the wealthiest 10 per cent of the population had incomes more than 20 times greater than the poorest 10 per cent (UNDP, 2001). And in most countries the trend during the decade was towards greater rigidity – and even deterioration – in income distribution; of 17 countries studied by ECLAC, only two (Honduras and Uruguay) showed a substantial improvement (CEPAL, 2001a). This rigidity or deterioration remained in spite of a relative recovery in economic growth (up to 1997) and social spending. Poverty mainly affects rural areas but, in absolute terms, most of the poor live in urban areas where almost half are children and young people. In the affected population, there has been no evidence of the growth of a middle class or any emergence from poverty (CEPAL, 2000b). In 1999, the unemployment rate reached 8.8 per cent, the highest during the decade, and similar to the rate during the period’s most severe crisis (ECLAC and UNEP, 2001). The slow reduction of poverty continues to be associated with a lack of economic growth and, in particular, with its limited effect on the labour market and flagging labour productivity. Between 1990 and 1997, 69 per cent of new jobs created, were in the informal sector, which accounted for 47 per cent of urban employment (CEPAL, 2000a). With the exception of Chile and Panama, the number of people employed in the informal sector grew while unemployment increased. In the 1990s, seven of each 10 jobs were in the informal sector - seldom permanent, unregulated and with no social security benefits (ECLAC and UNEP, 2001). Women’s participation in the labour market is an important trend. In 1980, women accounted for slightly more than a quarter of the labour force in Central America and South America. By 1999, they represented a third of the labour force in Central America and almost two-fifths in South America. In the Caribbean, where women’s participation had been higher, it had reached 43 per cent in 1997 (ECLAC and UNEP, 2001). This trend has been more pronounced than in any other region in the world. In general, there are more educated women in the labour force, although low family incomes have meant that more of the less educated women, girls and children are also working. The number of households headed by women has been growing until, according to the country, it has reached between a quarter and a third of the total. This puts more pressure on women to enter the labour market (CEPAL, 2001a). Estimates of work loads, income and unemployment rates reveal that women suffer great inequalities; furthermore, in some countries households headed by women tend to be the poorest (CEPAL, 2001a; UNDP, 2001).

Environment Outlook

There have been important improvements in education during the past two decades. Adult literacy rates are relatively high, with an average of 88 per cent in 1999 (UNDP, 2001) compared to 77 per cent in 1980 (UNESCO, 2000). However, inequality in income distribution is also reflected in differences in access to schooling, attendance and results (UIS, 2001). Coverage of basic services such as drinking water and sanitation has improved during the past 30 years. In 1960, only 33 per cent of the regional population had drinking water, and 14 per cent drainage. These figures are now 85 and 79 per cent respectively (PAHO, 2001). Violence, including homicide, has increased in the region. Family violence, particularly against women and children, has grown. It is estimated that half the women in Latin America experience at least one episode of family violence. (CEPAL, 2000b). In recent years, the trend towards finding peaceful solutions to conflict, whether internal (Central America, Mexico) or external (Ecuador, Peru) has continued, and this has encouraged the gradual advance of democracy. In Colombia, however, negotiations have failed to solve an internal conflict that has lasted for more than 40 years. Violence associated with drug trafficking continues to be a serious problem in many countries in the region. A solution is essential to ensure stability and sustainable development.

Demography The population grew by 85 per cent between 1970 and 2001 from 285 million to about 528 million (CELADE, 2002). However, the annual growth rate fell from 2.5 per cent to 1.5 per cent (CELADE, 2000), and if the current downward trend carries on, it could fall to one per cent in 2025 (ECLAC and UNEP, 2001). Fertility rates were halved from 5.3 children per woman in 1970 to 2.6 children per woman in 2000 (CELADE, 2002). Other contributing factors include higher levels of urbanisation and income and, in some cases, government birth control programmes. Estimated population growth rates for 2001-2002 are highest in Mesoamerica (around 1.7 per cent) and lowest in the Caribbean (around one per cent). The rate in South America is 1.4 per cent (CELADE, 2002). There has been sustained growth in urbanisation over the past 30 years, and in 2000 the urban population reached 73.7 of the regional total (CELADE, 2000). Migration to urban areas has continued. More of the urban population have access to electricity, drinking water and sanitary services.

variations between countries, and even within countries, largely explained by per capita income differences (PAHO, 1998). The highest life expectancy is in the Caribbean (74 years), followed by South America (73.5 years). However, life expectancy at birth is 20 years more in Cuba and Puerto Rico than in Haiti, while it is 10 years more in Venezuela and Colombia than in Bolivia. With the exception of Haiti, all countries in the region reached the objective of a life expectancy of more than 60 years, projected for the region in 1977 as part of the Global Strategy for Health for All by the Year 2000 (PAHO, 1998). More efficient health systems contributed greatly to this improvement by reducing the infant mortality index from 86per thousand births in 1970 to 37.8 in 1995 (CELADE, 2002). Most countries are in an intermediate demographic transition phase; sub-national variations are due to social and territorial inequalities. A third of the population is under 15 years of age and rural zones have the highest levels of fertility and mortality. Ageing of the population is becoming evident in countries like Argentina, Chile and Uruguay where adults over 60 years of age already account for more than 10 per cent of the total population (ECLAC and UNEP, 2001). A result of the temporary reduction of the dependent population (those under 15 years of age who usually do not yet earn their living and those older than 65 who are no longer wage-earners), is a phenomenon known as the demographic bonus. In the next two decades, in most countries in Latin America and the Caribbean it would be very useful to the transition to sustainable development if the economically-active populations improved their living standards by being able to save, spend or invest (ECLAC and UNEP, 2001). One response of the population to frequent economic crises is to migrate to developed countries. More than 17 million people in Latin America and the Caribbean live outside their country of birth, and half migrated during the 1990s. While the United States con-

In a large part of the region, the greatest drop in the mortality rate was recorded in the middle of the 20th century. Life expectancy rose from 65.8 to 72.5 years between 1970 and 2000 but there are considerable

tinues to be the principal destination, migrations to Europe are increasing.. According to conservative estimates, the flow of remittances to the region increased from US$5,200 million in 1990 to US$18,000 million in 2000. In some of the smallest economies, these funds have come to represent more than 40 per cent of export income, for example in El Salvador (52 per cent) and Jamaica (42 per cent - ECLAC and UNEP, 2001).

Governance

Science and technology Traditional information and communications technology continues to expand; the number of newspapers, radios, telephone lines and television sets has increased significantly over the past two decades. In addition, the use of personal computers, the Internet and cellular telephones has started to become common. However, there are still marked inequalities between countries, and a notable lag in relation to more developed regions. For example, although in Latin America use of the Internet has been increasing by more than 30 per cent per year, in 2005 only 12 per cent of the population will have access to it. Low household income is one limiting factor to the use of these technologies (UNDP, 2001).

With 8.6 per cent of the world’s population, the region has only 2.7 per cent of its scientists who, in 1988, produced 2.5 per cent of publications in this field (Massarani, 2001). There is still very little investment in scientific research: in 1999, it was about US$10,000 million or 1.9 per cent of the total global figure

·

(Massarani, 2001). Brazil invests about one per cent of its GDP in research and development (compared with the regional average of 0.53 per cent), and Mexico is in 11th place among the world’s principal exporters of high-technology products (UNDP, 2001). However, improvements in access to information and communications have reduced research costs, especially via the internet (Massarani, 2001).

The trend towards the decentralisation of authority is worldwide. Concern is growing about rights and opportunities, particularly in the field of human and women’s rights. The private sector reflects this trend with more horizontal corporative structures and decentralised decision-making processes. Some institutions have no formal command structures, for example the internet and NGO networks. In the public sector, the establishment of new democratic governments is evident, as is the empowerment of smaller and local government institutions, and the emergence of civil society as an important voice. During the past 20 years, two important political events have taken place in the region. The first is the change from military dictatorships to governments elected by popular vote, and all the countries now have popularly-elected governments. In recent years local governments and legal systems have strengthened, and the democratisation process has advanced. The second important achievement has to do with civil society participation and the creation of institutions such as NGOs. In 13 of 17 countries, 50 per cent or more of the population prefers democracy to any other form of government (Latinbarómetro, 2000). Increased citizen participation increased interest in aspects such as the environment, sustainable development and state reform, although some of these subjects have still not been included in decision-making policy processes. It is important to stress that the deterioration in the socio-economic situation of the region destabilizes government systems now in place and has recently given rise to serious political crises (most dramatically in Argentina, Bolivia and Ecuador). The configuration of stable and socially fair economic development is essential to sustainability in Latin America and the Caribbean.

Land

T

he Latin America and Caribbean region has the world’s largest reserves of arable land with an es timated 576 million hectares (ha) equal to almost 30 per cent of the total territory of 1,995 million ha (Gómez and Gallopín, 1995). In 1998 grassland covered almost 80 per cent of the region’s potential agricultural land; of the 20 per cent cultivated, very little is used for permanent crops (WRI, 2001). The region also contains 16 per cent of the world total of 1,900 million ha of degraded land, after Asia and Africa. The impact is relatively greater in Mesoamerica (where it reaches 26 per cent of the total: 63 million ha), than in South America (where it affects 14 per cent of the total: almost 250 million ha) (UNEP, 2000). Agriculture is a key to the evolution of Latin America and Caribbean societies. A large number of domesticated plants such as maize, tomato, cocoa and potatoes, of enormous importance to production, trade and consumption throughout the world, are native to the region. Regional agricultural ecosystems, a prime source of the population’s food, forage and fibre, are very di-

The growth of agriculture has, in general, intensified the use of natural resources and, as a result, exacerbated many of the land degradation processes in the region where, for example, there is constant threat of desertification. The past three decades have seen an increase in arable land and grassland at the expense of forests and wetlands, as well as an increase in the irrigated area and the use of agrochemicals. Negative effects include the emission of greenhouse gases, and damage to human health. All is not lost. The success of some land recovery experiments indicates that corrective action is possible.

Agricultural production During the 1990s, profits from the region’s agricultural exports doubled at an average rate of 6.4 per cent annually (from 3.3 per cent annually over the previous decade). This growth was achieved in spite of adverse climate conditions, political instability in some countries and general financial crises during the 1990s. As the decade drew to a close, growth became more

Environmental restrictions on agricultural land use Land is the primary substratum for vegetal and animal life on Earth, as well as an indispensable resource for essential human activities: agriculture, forestry production, water collection, settlements and recreation. However, the use of land to satisfy human needs is limited by environmental factors such as climate, topography and soil characteristics, as well as by very diverse social and cultural factors: population density, land tenure, markets and agricultural policies. The expansion for agriculture of land with severe environmental limitations in Latin America and the Caribbean is shown in the following table. Sub-region

marked in large countries like Colombia, Brazil and Argentina. In countries with less agricultural production, the trend slowed, even though strong support was given to exports during the period, as in Costa Rica and Chile (CEPAL, IICA, 2001). During the 1990s great changes took place in the structure and dynamics of regional agricultural production. Although there were increases in some traditional crops, the greatest growth was in livestock. By 1999, there was a 4.6 per cent growth in agricultural production, up from only 1.8 per cent in 1998, a year in which El Niño had a considerable effect on agriculture. The main contribution to the good results in 1999 was the strong 5.1 per cent growth in production in South America; in Brazil, there was a notable increase of an estimated seven per cent. In that same year growth was more modest in Mesoamerica, although the rate of 3.4 per cent was a considerable improvement over the 1.1 per cent recorded in 1998. However, agricultural production contracted during most of the 1990s and in 1999 fell by 1.1 per cent in the Caribbean (FAO, 2001a). In 1999, livestock production grew by 5.8 per cent, following a growth rate of 1.5 per cent in 1998. Cereal production, after dropping by 2.7 per cent in 1998, increased by almost 4.6 per cent in 1999. On the other hand, transgenetic crops - principally maize, soybean and cotton - showed a great expansion worldwide throughout the 1990s, covering a total of 45 million ha in 1996. Argentina has the third largest extension of these crops, after the United States and Canada (CEPAL, IICA, 2001).

Finally, between 1980 and 1999, the economicallyactive population in the agricultural sector fell from 35 per cent to only 21 per cent of the region’s total labour force. This substantial change was a result of a productive reconversion of agriculture, which meant that more labour became available for non-agricultural rural activities and there was a significant growth in migration from rural to urban areas (CEPAL, IICA, 2001; see the section on Urban Areas).

Land tenure Land tenure is an essential element in defining how biological diversity management functions. Experience worldwide has shown that inequitable land distribution and the lack of a clear legal definition of land rights can lead to irrational use of land and even the destruction of land resources. The basic problems of land tenure in Latin America and the Caribbean are the concentration of property and the lack of titles to the land. Both problems have their historic origins in the colonial system of land grants,which produced an agrarian property structure dominated by large properties (latifundios), and very small properties (minifundios). In spite of the many agrarian reforms introduced in the region, there have been no great changes in land tenure, with a growing concentration of agricultural properties (van Dam, 1999). This process was stimulated by population increases and by modernising agriculture with technologies that favour large agricultural extensions and increase the

42

Latin America and the Caribbean

number of landless farm workers (van Dam, 1999). This inequality of land distribution has significant consequences regarding access to fertile soils, irrigation and technology. At present, 38 per cent of the region’s rural population are smallholders and 31 per cent are landless farm workers (Jazairy and others, 1992). In Brazil, for example, 1.3 million smallholders own 2.6 per cent of permanent cropland, with an average holding of 1.5 ha. Although the landless movement in Brazil has gained some ground in recent years, this is one of the region’s highest averages. In Panama, 71.5 per cent of farm properties are smallholdings, which occupy 4.2 per cent of agricultural land. In Mexico, the average size of agricultural smallholdings is 1.4 ha (van Dam, 1999). From the environmental point of view, both the large agricultural properties and the smallholdings have adverse effects. On large properties, extensive livestock grazing or the use of mechanised crops causes land to become eroded and compacted, and it suffers from salinisation (inadequate irrigation) and chemical pollution. Smallholdings tend to increase deforestation, erosion and loss of soil fertility because of intensive use

with insufficient fallow periods (Jazairy and others, 1992). The environmental effects of the large property/ smallholding combination are particularly dramatic in Central America where smallholdings and crops lie on highly vulnerable hillsides, while extensive livestock farming and export crops are concentrated on lowlands. In this sub-region, more than 80 per cent of basic grains are planted on hillsides. This happens most in Guatemala, El Salvador and Honduras, where farm production is based on plots of less than five ha with very low technology. In addition, it is estimated that three-quarters of the total area of annual crops, and two-thirds of the total area of permanent crops, are planted on hillsides (López Pereira and others, 1995).

Expansion of agriculture and livestock farming The expansion of agricultural production led to the conversion of what used to be forest land; it also led to further exploitation of natural resources, particularly land

Land use and soil conditions: the case of Jamaica As in the rest of Latin America and the Caribbean, the land tenure regime in Jamaica is inequitable and few land conservation and recovery methods are used either on large properties or on smallholdings. In the 1970s, land reform favoured large properties in the form of cooperatives based on mechanisation, increased irrigation (on 12 per cent of arable land in 1983), intensified use of crops and monoculture. Environmental effects have been typical of large properties with intensive agriculture: land erosion and soil compacting from mechanisation, salinisation caused by deficient irrigation systems and chemical pollution although, unlike the rest of the region, Jamaica did not show any marked increase in the use of the agrochemicals that are a feature of this agricultural model. However, in these types of properties often only less than one-sixth of the land is cultivated so that absolute returns are low, however high the level of intensification in the part that is cultivated. In the 1980s one quarter of Jamaican territory was under cultivation and more than 90 per cent of farms covered 4 ha or less. These smallholdings were concentrated in ecologically fragile mountain areas of low fertility and were only suitable for forest protection of water sources. They used traditional agricultural methods including slash-and-burn cultivation and organic fertilisers, especially cattle manure. The farms had no physical infrastructure or basic services, farmers had little or no access to suitable technology for their ecosystems, little or no credit and very little schooling. In general, the expansion of large agricultural properties and the marginalisation of peasant farmers have meant that the land now has fewer fallow periods and there is less crop rotation. Other environmental effects of this agricultural model are deforestation of mountainsides and a reduction in the number of draught animals, since agricultural expansion often takes place at the expense of pastureland. In zones with smallholdings, land degradation tends to increase, especially the loss of fertility from erosion, which is reflected in a marked drop in production. Intensive use without fallow periods and the lack of crop rotation and adequate technologies are also reflected in floods and in a sharpening of the effects of drought in both the region itself and lowland and even in coastal ecosystems, especially in the small Caribbean islands. Comparative studies indicate that the effects of land ownership detailed here for Jamaica are common throughout Latin America and the Caribbean. Sources: van Dam, 1999 and Library of Congress, 2000.

and water, worsening the land degradation process. Between 1970 and 2000, the area of agricultural land (including grassland) expanded in Latin America and the Caribbean to five per cent of the total land area, reaching 37.7 per cent at the end of the period (FAO, 2002a). The largest increases were in the Caribbean and South America (16.1 and 15.8 per cent, respectively), although in the past decade less land has been devoted to agriculture in the Caribbean. It is important to note that most agricultural land in the region is grazing land; 79.2 per cent of the total agricultural land in 2000. This proportion decreased by 3.9 per cent between 1970 and 2000 (with a pronounced fall of 21.2 per cent in the Caribbean); this indicates the continued inefficient use of land, both in terms of regional food security and the environmental impact of livestock on land and water.

bour force. This is the case of the Legal Amazonia in Brazil and of livestock companies in Bolivia that rented land to peasant farmers to be cleaned and cultivated, and then got it back deforested when their leases expired (UNEP, 2002). This change in land use had another significant impact, this time on a global scale. It increased the emission of three gases which play an important role in the global warming process (FAO, 2001b; IFA and FAO, 2001; see section on Atmosphere): carbon dioxide (a consequence of deforestation), methane (basically from using the land for livestock) and nitrogen oxides (from the use of fertilisers on crops and grasslands).

The expansion of livestock farming in many areas, such as the Amazon, to meet national and international market demands has lessened the productive capacity of the land. In Nicaragua, the load capacity of pastureland has been reduced by between 50 and 85 per cent, from 1.0 to 0.15 and 0.5 animal units per hectare (Pratt and Jones, 1999). Breeding has also fallen by between 50 and 80 per cent, due to nutritional deficiencies in pastureland. Regional livestock expansion could not have been successful without strong support from governments through tax incentives, credit policies, the construction of roads and the availability of a trained and cheap la-

Land degradation, one of the most serious environmental problems in the region, originated in processes such as erosion and acidification, the loss of organic material, soil compacting, the loss of nutritive elements, chemical pollution and salinisation. As a consequence, it is estimated that more than three million square kilometres of agricultural land in Latin America and the Caribbean have suffered a significant loss of productivity. In the region, erosion is the main cause of land degradation, as well as subsequent losses of nutrients and productivity that affect 14 per cent of the territory in South America and 26 per cent in Mesoamerica (Oldeman, 1994). The Global Assessment of Soil Degradation (GLASOD) indicates that 74 per cent of Central American agricultural land was degraded in 1990

Land use change and greenhouse gas emissions An important consequence of increasing cropland by eliminating forests is the emission of greenhouse gases, an effect aggravated when, after deforestation, the land is used for methane-emitting livestock raising. In 1994 carbon dioxide emissions caused by change in land use and forestry in the region accounted for approximately 28 per cent of the emissions from the energy and industrial sectors. In the Caribbean, on the contrary, the gases captured in reforestation and forestry plantations account for 55 per cent of the emissions generated by the other two sectors. Altogether, the region emits 48.3 per cent of the global total of carbon dioxide resulting from change in land use, principally through deforestation, and 9.3 per cent of the methane from anthropogenic sources, especially livestock. Concerning methane, while 30.0 per cent of world emissions come from livestock, the figure rises to 71.4 per cent in South America and is 48.0 per cent in Mexico (see the section on Atmosphere).

(Oldeman and others, 1991). The countries most endangered by land deterioration are the smallest, such as many Caribbean islands (for example, Haiti), and Central American countries such as El Salvador. Also particularly vulnerable are countries such as Nicaragua, Guatemala, Bolivia and Paraguay, whose economies depend mostly on agriculture. Many of these processes vary in intensity according to location, inclination (land with a slope of more than eight per cent) or the use of irrigation and agrochemicals. The limitations imposed by the degree of fertility and inclination are also reflected in production levels. Soil fertility comes from an interaction among multiple factors: organic matter content, availability of nutrients (particularly nitrogen, phosphorous and potassium), water retention capacity, acidity, salinity and physical characteristics like soil structure and texture. The Latin America and Caribbean region has quality limitation parameters comparable to the world average (Wood and others, 2000). Only 12.4 per cent of its agricultural land has no fertility limitations (compared to a world average of 16.2 per cent).

·

However, some factors have alarmingly high levels, duplicating global averages: almost 40 per cent of land in the region has low potassium reserves and just under one-third, especially in the tropical zone, has aluminium toxicity. A reduction in cereal yields per hectare has been detected in some critical places (in rice, maize, wheat or sorghum), indicating nutrient deficiencies. Fertility is being lost in zones like the northeast of Brazil, the north of Argentina and some areas in Paraguay, Bolivia, Colombia and Mexico (WRI, 2000). It is true that yields are growing or remain stable in parts of Uruguay, Venezuela, Ecuador and Nicaragua. However, the growth in yields should not always be interpreted as a positive sign; it may be the result of unsustainable agricultural practices, based on intensive agrochemical use. Salinisation does particularly serious damage to the soil, because it is hard to treat and can lead to desertification. Salinisation from irrigation is particularly notable in Cuba (1.0 million ha), Argentina (0.6 million), Mexico (0.4 million) and Peru (0.3 million) and, more specifically, in arid regions in the Brazilian north-

east, the centre of Chile and some areas in Central America (UNESCO and others, 1978; FAO, 2000).

Agrochemical pollution

Land degradation has increased poverty in the region and this, in turn, has been the cause of greater environmental deterioration, particularly of soils; a cyclical phenomenon that has been observed especially in silviculture and agriculture (both peripheral and marginal activities). Economic losses resulting from this cycle may be high; for example, the losses from soil erosion in different regions of Mexico vary from three to 13 per cent of the agricultural gross domestic product (WRI, 2000).

Chemical soil pollution is another growing environmental problem of in Latin America and the Caribbean, a result of the intensification of agriculture and the use of pesticides over the past 30 years. Agricultural technology has increased production throughout the region, but environmental costs have been high. In particular, the loss and exhaustion of nutrients in the region may be an important cause of the increase in the use of fertilisers, which grew from 2.9 to 13.2 million tonnes between 1970 and 2000 (FAO, 2002c).

Loss of soil nutrients Gradual intensification of agricultural production in the region has been the most important factor of soil nutrient exhaustion which, in South America, has affected 68.2 million ha (43.7 million to a moderate or severe degree). Organic material stored in the soil is an important indicator of the health of the agricultural ecosystem. It has been 2 estimated that the 6.2 million km of agricultural land in Latin America and the Caribbean contain some 59,000 million tonnes of carbon in the top metre of soil, equal to 15 per cent of the world total of agricultural land carbon. However, the average density of carbon in the region's soil is 95 tonnes per hectare, a value somewhat below the global average of 102 tonnes. The annual loss of nutrients for the period 1983-1985 was more accentuated in the Caribbean, with 67 kg of nitrogen, phosphorous and potassium lost per hectare annually, followed by South America with 65 kg. Ten years later these levels had improved, so that for the period 1993-1995 the Latin American average was 54 kg per hectare annually, compared to 59 kg in 1983-1985.

Fertilizer consumption in Latin America When compared to global consumption, Latin America is an important consumer of fertilisers, representing 9 per cent of the world total and with an annual growth rate of 4 per cent. Although regional fertiliser consumption is cyclical, total consumption in 2000 was more than four times greater than in 1970. Brazil, the largest country in the region, accounts for about 50 per cent of regional consumption, Mexico 15 per cent and Argentina 8 per cent.

In 1995, credit problems caused a reduction of 9 per cent in consumption although, when the situation improved for Brazilian producers, total consumption of nutrients again increased, this time by 35 per cent. The cycle continued: in 1999 consumption decreased by 7 per cent, due to economic problems and low prices for agricultural products, with imports of fertilisers also falling by 6 per cent in that year. Between 1995 and 1998 there was a large increase in production of beans and soybeans, with nitrogen consumption rising by 0.3 million tonnes, while phosphate and potassium salts increased by 1.2 million tonnes.

Mexico is closely associated with the United States to which it sends close to 80 per cent of its exports, and it is affected by its neighbour's economic cycles. In 1999 drought in the north of Mexico had an effect on the consumption of fertilisers for wheat and maise. Finally, the shortage of urea that year was compensated by more ammonia imports.

The impact of agrochemical pollution on soil and water and, therefore, on human health, is of prime concern. One of the main impacts of the use of agrochemicals is the growing nitrification of the land and problems caused from eutrophication (in surface waters) and the appearance of red tides in coastal zones. There are also the effects of the emission of nitrogen greenhouse gases.

1990s. Consumption increased from 132,736 tonnes in 1980 to 446,400 tonnes in 1998, while imports grew from 5,577 tonnes in 1984 to 15,350 tonnes in 1997 (OdD-UCR and UNEP, 2001; UCH and others, 2000). In Peru the use of fertilisers in 1998 reached 520,411 tonnes, with an increase of 19 per cent over the previous year. However, in 1999 it fell by two per cent (CONAM, PNUMA, 2001).

Land pollution by agrochemicals does not happen only because of their excessive or inadequate use, but also when they are used according to the manufacturers’ technical recommendations. The environmental impact of agrochemicals is particularly notable in the case of fertilisers which cause massive global nitrification of land and water (UNEP, 2000; IFA, 2001). Serious pollution has also occurred as a result of the sterilisation of banana plantations; from the use of nematocide copper in Mesoamerican countries such as Costa Rica. This has also affected people and coral reefs (van Arsdale, 1991).

The United Nations Organisation defines desertification as the degradation of land in arid, semiarid and dry subarid zones, caused by such factors as human activities and climate variations. These ecosystems cover more than a third of the world’s land surface and are highly sensitive to inappropriate land use, especially to overexploitation. The land may lose productivity because of improper irrigation, deforestation, excessive grazing, poverty and political instability. This can result in a food crisis and even famine and desertification, and is therefore considered a global problem. Some crises begin in areas that suffer from

pay for itself in only seven years (PNUMA/ORPALC, 2002).

Desert or arid areas cover a quarter of the territory in Latin America and the Caribbean (some 5.3 million km2). Water shortages and erosion increasingly affect a large number of islands in the eastern Caribbean, to which can be added arid zones in the Netherlands Antilles, Cuba, Haiti, Jamaica, Puerto Rico and the Dominican Republic. In Mesoamerica, Mexico, a predominantly arid or semiarid country (especially in the north) is of particular importance. In South America numerous countries are affected. Extensive semi-arid regions are covered by tropical savannah in the Brazilian northeast, and on the Pacific coast the desert extends from the south of Ecuador, along the Peruvian coast and the north of Chile. An arid strip stretches from Patagonia in the south of Argentina to the north of the Chaco in Paraguay. The dry Andean high plains cover extensive areas at altitudes of between 3,000 and 4,500 metres in Argentina, Bolivia, Chile and Peru (PNUMA/ORPALC, 2002; UNCCD, 2002a).

Policy responses

Overgrazing, poor irrigation techniques, deforestation and removal of vegetal cover for domestic uses, are among the factors that endanger 70 per cent of the highly vulnerable dry soils, which also suffer from a significant degree of desertification (FAO, 1998b). In Latin America and the Caribbean, 313 million ha are affected by desertification (250 million in South America and 63 million in Mesoamerica), causing annual losses of approximately US$2,000 million. While the cost of restoring the region’s degraded lands has been estimated to be US$13,000 million, it is an investment that would

In the past 10 years, and as a result of the United Nations Conference on the Environment and Development (Rio de Janeiro, 1992), the traditional focus of agricultural policies, previously concentrating almost exclusively on aspects of land production and productivity, has been broadened to include integrated and participatory planning for sustainable management of land resources (FAO and UNEP, 1997; FAO and UNEP, 2000). Agenda 21, which was a result of the Rio conference, proposed the integration of biophysical, social and economic themes, active participation by local communities and strengthening of institutions to satisfy sustainable development objectives. Substantial elements of the new integrated focus include considerations of the importance of food security and the capacity of agricultural ecosystems to provide a continuous supply of food, forage and fibre, among other environmental goods and services. The overuse of agrochemicals in Latin America and the Caribbean, which has been associated with a significant deterioration of the environment, brings with it a growing immunity to common pests and the appearance of new ones, as well as negative effects on human health. All this has led international organisations and governments to implement integrated pest control projects for an increasing number of crops (Hall and Menn, 1999). These initiatives have caused specific

policies to be adopted on integrated systems (FAO, 1998a). Many countries in the region have also undertaken important experiments on agricultural conservation designed to increase productivity while, at the same time, reducing erosion and reversing the loss of soil fertility, aimed at improving rural life and restoring the environment (FAO, 2001b). Some of the most notable of these experiments are reducing or eliminating slash-and-burn agriculture in some areas in Honduras, introducing minimum cultivation practices on Brazilian smallholdings, freeing areas for cultivation by intensifying livestock farming in Costa Rica, and the massive adoption of zero cultivation in El Salvador and organic agriculture in Cuba (FAO, 2001b; CIGEA, 2001). These experiments show that the development of intensive production systems in the tropics is technically feasible and economically profitable through improved land use, agricultural biodiversity and carbon fixing. For many decades, problems of land degradation have also featured in global and regional discussions. The principal declaration of policies in this field is the United Nations Convention to Combat Desertification (UNCCD), drafted in 1994 as a result of the Rio summit of 1992. The 33 countries in Latin America and the Caribbean are parties to the convention and some countries have received financial support to prepare their national plans and reports (UNCCD, 2002a; 2002b).

action programmes; another 13 countries are in the process of formulating or approving similar programmes (UNCCD, 2002b). This action has encouraged the establishment of such programmes in countries like Peru and Argentina, as well as the creation of monitoring systems that are already in use (PNUMA/ORPALC, 1999; Universidad de Buenos Aires, 2001). The third round of Global Environment Facility (GEF) financing anticipates emphasising activities aimed at improving coordination between the conventions. At national level, in particular, there is an urgent need for greater efficiency in administering resources and combining efforts to combat desertification, to conserve biodiversity and protect wetlands. A regional programme has been prepared to apply the convention, with nine new priority projects and six sub-regional action programmes: the Great American Chaco, the American Puna, Mesoamerica, the Española, the programme of the eastern Caribbean islands on biodiversity and land degradation, and the bilateral Chile-Argentina programme on gender perspectives (UNCCD, 2002b). There is also a project under way on the harmonisation of regional public policies to combat desertification, starting with the Mexican government’s experience (PNUMA/ORPALC, 2003a).

At the World Summit on Sustainable Development, held in Johannesburg (South Africa) in 2002, participating countries reaffirmed the commitment to implement the UNCCD through national action plans, mobilising the necessary resources and seeking concerted action with other convergent multilateral agreements such as the Framework Convention on Climate Change and the Convention on Biological Diversity (UN, 2002). However, in the 28 national reports presented that year to the Committee to Examine the Application of the Convention, most countries in the region mentioned limitations encountered in applying it. One such limitation is a bias in the agenda towards policies that favour economics but ignore the economic implications of desertification. Also recognised are problems such as ineffectual national liaison officials, usually because they are frequently changed, and weak mechanisms to finance policies in this field (UNCCD, 2002b). Public awareness campaigns have been organised. National reports emphasise the importance of public participation in efforts to combat desertification, and nearly a third of the reports mention the vital contribution made by the International Network of Non-Governmental Organisations against Desertification and Drought (RIOD) in applying the convention (UNCCD, 2002b). In 2002, six countries in the region (Argentina, Bolivia, Chile, Cuba, Mexico and Peru) approved national ·

The Great Chaco sub-regional action programme involving Argentina, Bolivia and Paraguay, in spite of not having received all the funds needed to carry out its activities, has made important progress since its initial forum in May 2000. It has organised a meeting of NGOs on desertification and rural poverty (Argentina, June 2001) and prepared the Declaration of Cooperation for Sustainable Development in the Great American Chaco (Argentina, September 2001), which sets priority objectives. At the institutional level, monitoring units have been set up in participating countries; locally, various indigenous and agricultural communities have managed microprojects (UNCCD, 2002b). Argentina, Bolivia, Chile, Ecuador and Peru participate in the Sub-regional Action Programme on Sustainable Development in the American Puna. At its coordination meeting in Bolivia in May 2001, advances were

made in defining the programme’s principles and concepts, priorities and strategies, its proposed institutional framework, and a programme of activities. The programme is concerned with the land tenure problem, deficient land regulation and the elimination of incentives for expanding the agricultural boundary. Participation of indigenous populations and community associations planning and implementing the programme is encouraged (including the Aymará Parliament for indigenous communities, established in 1996 to protect watershed resources and ecosystems affected by non-sustainable activities in the Andes). In January 2002, official recognition was given to the declaration on the sustainable development of the American Puna that makes express reference to the UNCCD, marking an important stage for this sub-regional programme. The programme’s institutional framework has been strength-

Towards owards harmonizing regional public policies to combat desertification Within the framework of the Convention to Combat Desertification, and with the support of the Global Mechanism created to channel technical and financial resources to apply the convention, the United Nations Environment Programme, Regional Office for Latin America and the Caribbean, is executing a project to harmonise regional public policies (PAPP). The project was approved by countries attending the convention's Fourth and Fifth Regional Meetings in 1998-1999; its objective is to contribute to the struggle against desertification by adopting appropriate management strategies for natural resources, taking as a basis the Mexican government's preliminary assessment, in 1998, of public policies and the degradation of natural resources. To contribute to improving the environment and implementing an early warning system on environmental problems, the project includes undertaking six pilot experiments in the same number of countries in the region, as well as holding methodology and systemisation workshops. A study will also be formulated on the international framework for reforms to rural development policies and a database prepared on policy instruments, both inputs designed to orient the countries' harmonisation work. The Mexican government has now prepared a design to integrate the National System to Combat Desertification (SNLD) and the results of the harmonisation work will be included in the legislation process on the Law of Sustainable Rural Development. This law includes the process of land use contracts that provide a suitable instrument to harmoniously coordinate three policy elements in this field: the application of publicly-funded programmes to support production, the concept of desertification as a global soil degradation process, and the SNLD itself, which is a national coordinating body. Congress is also debating a draft law on land conservation. As complementary support for these national exercises, the project to harmonise regional public policies has formulated, in coordination with the Chapingo Autonomous University, the preparation of a database on rural policy instruments. The database will provide systemised information on experiences in several countries throughout the world, starting with global research on public policy instruments meant to improve and conserve land. With this it is sought to learn from already formulated and executed experiments, and to make the countries' work on reform more effective. An international study has also been made on existing trends and margins to harmonise rural development policies against desertification. The study presents a panorama of the state of desertification in the region, gives a description of the instruments in use and profiles the main international bodies that define the international framework for policies in this field.

The regional programme has also made important advances in developing parameters and indicators to create and monitor an information network to combat desertification and apply integrated watershed management (UNCCD, 2002b).

Among the most important actions directed at halting land degradation in Latin America and the Caribbean, priority should be given to those densely-populated countries with accelerated rates of output and fertility loss. These responses may be backed by policies that allow the participation of producers’ organisations, thus creating institutional conditions and incentives to increase land conversion capacities. Many local initiatives on land conservation, reduction or diversification of inputs, cover crops and agroforestry systems, have halted land degradation or even reversed it in many regions in Latin America. The boom in organic agriculture in some countries, is an encouraging sign; emphasis is on maintaining the soil’s natural fertility. These isolated experiences should be included in national and regional agricultural policy agendas.

Action has been taken, globally and regionally, to strengthen collaboration and exchange of information about combating desertification, including the Third High Level Forum on Cooperation between Africa and Latin America and the Caribbean, held in Venezuela in 2002 (UNCCD, 2002b). There is a trend for global multilateral agreements concerned with desertification to be converged and coordinated. To unify the collection and dissemination of information on environmental themes worldwide, under the coordination of UNEP, letters of understanding have been signed between the secretariats of global conventions such as UNCCD, the Convention on Biological Diversity, the United Nations Framework Convention on Climate Change, the Con-

Forests

I

n 2000 the Latin American and Caribbean region had 25 per cent of the world’s forest cover, some 960 million hectares (ha), on only a seventh of its territory (FAO, 2001a). The proportion of forested areas is much greater than the global average; 47 per cent of regional territory is covered with forests, while the world figure is 30 per cent (FAO, 2001a). South America has 92 per cent of regional forests, mainly in Brazil and Peru, which are among the 10 countries that account for two-thirds of the world’s forests (FAO, 2001a). Planted forests make up a little more than one per cent of the forested area in Latin America and the Caribbean and almost half are in Brazil (FAO, 2001a, 2001e). The woody biomass of Latin America and the Caribbean is the world’s largest, with more than 17 per cent of the global average of 109 tonnes per hectare (FAO, 2001a). South America has 54 per cent of the world total and Brazil alone has 27 per cent. This underlines the importance of the region –and Brazil in particular– in capturing or emitting atmospheric carbon because of changes in use, a key element in regulating the planetary climate change process. No detailed analysis is available of world or regional forest cover between 1970 and 2000, not only because

Latin America and the Caribbean is the most heavily forested region in the world, but it lost almost 47 million hectares in the period 1990-2000 (second only to Africa). Note: The dark green shows the closed forest (areas with more than 40% of trees higher than 5 meters); the medium green represents open forests (with a cover of between 10 and 40 percent) or fragmented trees, and the light green represents other forest lands, with bushes or wild grass.

during that decade, half of the loss was in Latin America and the Caribbean (FAO, 2001a). According to these estimates, the regional percentage of global forest cover fell from 25.5 to 24.9 per cent in that period. During the past 20 years, world loss of natural forest has continued at approximately the same levels (FAO, 2001a, 2001c). In tropical forests, the loss continues at an “alarmingly high” rate of close to one per cent annually. In the specific case of the South American tropical forests, although there was a reported reduction in deforestation rates in the 1980s and 1990s, a sample taken from satellite data did not find any statistically-significant differences between the two periods (FAO, 2001c). Because of their socio-economic role in most Latin American and Caribbean countries, the fate of natural forests is critical for the region. These ecosystems supply wood for domestic and industrial consumption and for exports that earn foreign currency. Many communities have coexisted with forest ecosystems for generations. Forests provide traditional forest goods – such as food, medicines and other non-wood forestry products - to many rural populations (Bryant and others, 1997), as well as environmental goods and services (carbon

capture, containing natural disasters, recharging aquifers, halting erosion and soil loss).

Deforestation trends and causes The greatest reduction in forests during the 1990s was in Africa where 5.3 million ha were lost every year. Latin America and the Caribbean was in second place, with a loss of 4.6 per cent of its forest cover between 1990 and 2000, a total of 46.7 million ha, with an average annual deforestation rate of 0.5 per cent. This is over double the global average (FAO, 2001a). According to FAO, 88 per cent of the region’s forest areas are found – in descending order – in seven countries: Brazil, Peru, Mexico, Bolivia, Colombia, Venezuela and Argentina, with Brazil accounting for 56 per cent of regional forests or 544 million ha (FAO, 2001a). Almost half the total loss of cover between 1990 and 2000 was in Brazil (23 million ha, or 4.2 per cent of the country’s forests), with Mexico (6.3 million ha) and Argentina (2 million ha) far behind. Annual deforestation rates were more than twice as high in these two last-men-

Assessment of world forest resources: definitions, methods and sources The last assessment made by FAO of world forest resources –the 2000 FRA– establishes new reference statistics for the year 2000 and to analyse trends from 1990 (FAO, 2001a). In its new estimates, FAO includes (as it did in the earlier assessment for 1990) natural forests and forest plantations but now, for the first time, applies a uniform and broader definition of the concept of forest for all countries, both for 2000 and 1990, thus correcting its previous assessment. In the 1990 FRA, FAO applies the concept of forest to trees at least 7 metres high on areas larger than 100 ha, with crown cover of 10 per cent for developing countries, and 20 per cent for industrialised countries. The definition now includes all wooded territory with trees at least 5 metres high and a crown cover of more than 20 per cent on an area of more than half a hectare. Therefore, while estimated world cover for 1990 is 15 per cent higher in the new study, this is due in large part to the use of a broader definition of forest for all countries (FAO, 2001c). The increase is also explained by the use of new forest inventories after 1990 (as in the case of Mozambique), or by reclassifying as forest areas those previously classified as other wooded land (in Kenya, for example). For developing countries, the 1990 FRA estimated forest cover trends in the period 1980-1990 by using a mathematical model based on demographic factors to project the little national information available (FAO, 2001c). The model was not used for the 2000 FRA as it was recognised there was little relation between these factors and the change in cover. Instead, an extrapolation method was used for the years under review (1990, 2000) based on greater availability of data than in the earlier assessment, which in turn was corrected with experts' criteria and the results of satellite information sampling for tropical forests. The exercise encountered many limitations, one of them being that more than half of the developing countries had only one forest inventory, and more than a quarter had none at all (FAO, 2001a). Of 45 countries in Latin America and the Caribbean, 19 (four in the Caribbean) had inventories comparable by country, but 14 countries had no inventories (31 per cent, 13 in the Caribbean) and four had only a partial inventory. Furthermore, the inventories are very dissimilar as to their reference year; the most recent statistics for Brazil, for example, whose forest cover is the region's most extensive, are for 1989 (FAO, 2001e). The inventories can also differ from the statistics prepared by FAO; In Mexico, for example, the National Forest Inventory for 1993-2000 shows annual deforestation rates above 800 000 ha, while FAO indicates 631 000 in the period 1990-2000 (Morán and Galleti, 2002).

tioned countries (1.1 and 0.8 per cent respectively, compared to 0.4 in Brazil). Only three countries showed increases in their forest cover during the period, but to a much smaller degree than the losses suffered in countries with more forests: Uruguay (501,000 ha), Cuba (277,000 ha) and Guadalupe (15,000 ha) (FAO, 2000). Annual rates of change in forest cover varied considerably from one sub-region to another in the 19902000 period. Caribbean countries had the lowest average annual rate of change in forest cover (0.2 per cent), followed by South America (0.4 per cent) and Mesoamerica (1.2 per cent - FAO, 2000). There are also great differences within each subregion. In the Caribbean, for example, Saint Lucia and Haiti showed high rates of deforestation (4.9 and 4.6 per cent annually, respectively), which was not the case in Cuba and Guadalupe. In Mesoamerica, deforestation rates range from 4.6 per cent annually in El Salvador to 0.8 in Costa Rica. Nicaragua, Belize, Guatemala and Panama resemble El Salvador - their rates are above the sub-regional average; only Costa Rica, Honduras and Mexico are below the average. In South America, deforestation rates in Ecuador and Argentina are notably higher than the sub-regional annual average (1.2 and 0.8 per cent, respectively), while the others maintain rates similar to the sub-regional average. NB - in 1990-2000 South America had 40 per cent of the world’s deforested area (FAO, 2001a).

Pressures The main pressure affecting natural forests in the region is the conversion of forest land to other uses. More land is made available for agriculture, livestock

and urbanisation, as well as for road building and other infrastructure (electric networks, dams), or for mining. Other significant pressure comes from harvesting timber, forest fires and climate phenomena (Bryant and others, 1997). Negative effects are also caused by biological phenomena such as the proliferation of pests, often reflecting ecological changes caused by humans, particularly due to exotic forestry species monoculture (Monge-Nájera, 1997). Unlike other regions, the loss of forest cover is explained more by the expansion of transport networks, extensive livestock-raising and mechanised agriculture (especially soybeans) than by timber harvesting, which occurs in relatively few countries (Kaimowitz, 1996; Kaimowitz, 1997). Penetration roads into the forest, and associated timber harvesting, expand the agricultural boundary, and contribute to forest degradation through loss of biodiversity. Regionally, as in the rest of the developing world, timber is harvested, to supply fuelwood and, to a lesser extent, for industrial production and sawmills. In 2000, regional production of roundwood and sawnwood (including all kinds of industrial roundwood and fuelwood) was 432.7 million m3, almost twice the 1970 production (FAO, 2002a). In the same year, 61.6 per cent of this production was used for energy (fuelwood and charcoal), half in Brazil and almost a third in Mesoamerica (particularly in Mexico and Guatemala). Industrial production is concentrated on a regional market restricted to only a few species, which places them under great pressure. In particular, selective timber harvesting in remote areas is threatening important native species such as cedar (Cedrela odorata) and mahogany (Swietenia macrophylla -UNOFOC and others, 2000).

Use of fuelwood as a source of energy in Mesoamerica An analysis of the regional generation of energy from wood and its derivatives reveals that over the past 30 years there has been a constant increase, particularly in Mesoamerica and Brazil, where consumption is greatest and represents 48.0 per cent of the total. In Mesoamerica, with 17.5 per cent of the total for the region, the main consuming countries are Mexico (8.7 per cent of the regional total), Guatemala (3.4 per cent) and Honduras (2.0 per cent). Two-thirds of Mexico's timber potential is found in temperate forests, and half the timber produced comes from pine forests. Of total processed volume, 80 per cent is used for energy by producing fuelwood and vegetable carbon. In Central America, much of the fuelwood comes from agricultural land, live hedges and secondary forests. Of harvested wood, 92 per cent is used as fuelwood, both for domestic and industrial use, although with strong contrasts between the countries in the sub-region. For example, domestic fuelwood use reaches 1.5 cubic metres per capita annually in Honduras, but only 0.34 in Belize. Sources: UNOFOC and others, 2000; FAO, 2002a, 2002b.

Subsidies for Mexico's Mexico's agriculture and livestock sector Mexico's agriculture sector grew by more than 4 per cent annually from the end of the 1940s until the mid-1970s, largely due to government funds allocated to provide direct and indirect support to this branch of economic activity. Added to the lack of adequate legislation and monitoring, this stimulated the expansion of agriculture into forest areas. Besides direct investments in the sector, end products including fertilizers, pesticides, fuel, electricity, water and seeds, were also subsidised. In addition, crops were insured, productive activities were promoted by parastate organisations and loans were given with little likelihood of repayment. Just the opposite was the case in the forestry sector, where credit was restricted and the few people with access to it had to discount their activities at very high rates because the sector was considered to be too risky. By 1965, most of the best land was already under cultivation and productivity per hectare had stagnated. From that time until 1980, the agricultural gross domestic product grew at only 2.4 per cent but protectionist policies continued from 1970 until 1998: measures included subsidies for maize, price guarantees, high taxes on permanent crops (sugar cane, coffee, cocoa) and trade restrictions. In recent years the government programme PROCAMPO has removed price subsidies and replaced them with direct payments to producers according to the areas planted. Although no systematic studies have been made on their influence, anecdotal evidence points to a great propensity in rural areas to clear forests in order to expand areas for cultivation and thus claim subsidies under the programme. Sources: Morán and Galleti, 2002.

Economic pressure and poorly-directed subsidies or incentives have been a main cause of the conversion of forest soils into land for agriculture and raising livestock. In some countries this has become worse as a consequence of policies to increase exports that provide the foreign currency needed to pay for imports and repay the foreign debt (Contreras-Hermosilla, 2000). Land tenure and institutional arrangements that govern forest management are also an important factor influencing forest degradation or conservation (Ostrom, 1990; Gibson and others, 2000; FAO, 2001a; Geist and Lambin, 2001; Gibson and Lehoucq, 2002). In many cases, strategies to protect forest environmental services depend on forms of community or socialised administration (such as may be developed by certain indigenous groups, community organisations or even the State itself). In the Amazon and Mesoamerica, indigenous people are the legal owners of significant areas of tropical forest as well as of temperate forest in the southern cone. In Mexico, ejidos and communal land predominate. In cases where much forest land is in the hands of the State, it releases part of them to private interests through private forestry concessions (as in Bolivia, Guyana, Suriname and other countries). When property rights over land are not clear, people tend to clear forests and build on those areas to establish a claim to them. A primary pressure on forests is the predominance of a short-term and strictly financial view of the economic benefit of identifying development options. Notwithstanding the important social and cultural function

·

of forests in the region – in particular for communities and social groups that directly depend on them for their subsistence – this feature of the forests is often not taken into account in infrastructure development plans and productive investments. In many investment projects, decisions on the permanence of forests, or on a change of land use. both private and public, are more frequently based on conventional cost-benefit analyses (focussed on financial gain) rather than more wide-ranging analyses that include economic, social and environmental considerations.

Forest fires and hydrometeorological threats Fires continue to affect important extensions of forests in the region. In Central America more than 2.5 million ha of forests caught fire during the 1997-1998 El Niño, and one million ha of agricultural land were also damaged. In Nicaragua, Guatemala and Honduras 900,000, 650,000 and 575,000 ha, respectively, were lost. In 1998 those countries suffered the impact of Hurricane Mitch, which caused loss of forest cover which exacerbated landslides and floods. In Bolivia, fires affected three million ha. In the state of Roraima in Brazil, fires devastated more than five million ha, including 1.4 million ha of tropical forests (Cochrane, 2002). In the same year another 850,000 ha caught fire in Mexico. In 1999, the NOAA-12 satellite images identified about 219,000 heat sources in South America. Approxi-

Forest rangers: indigenous community forest management There is an international dispute about the need to keep biodiversity users away from protected areas to guarantee their conservation. Many opponents of this thesis argue that biodiversity can be maintained and even improved through sustainable use by promoting different mechanisms –such as community management– to make conservation part of development. When it comes to forest resources, there are multiple experiences in Latin America and the Caribbean in community forestry (within and outside protected areas) that make this second thesis credible. The ancestral experience of many indigenous communities is of great value in this respect, especially in countries with large pre-Columbian indigenous populations such as Mexico, Guatemala and Bolivia. The importance of indigenous inhabitants to the sustainable administration of forests is also essential in places whose indigenous populations are proportionally smaller: Brazil, among countries in Amazon, and Chile, among countries in the southern cone. In Mexico, for example, it is estimated that 80 per cent of forest land is in the hands of one-seventh of the population living on ejidos and other indigenous community land. But even countries with very small aboriginal populations, like Costa Rica, bear witness to the notable function of indigenous groups as forest rangers. In that country, protected territory belonging to indigenous communities adds 22 per cent to protected wild areas with more than 41 per cent of the total extension under forest cover. Sources: Cabarle and others, 1997; Fernández-González, 1999; UNOFOC and others, 2000; FAO, 2001a; Gibson and others, 2000, 2002; Obando Acuña, 2002.

mately 66 per cent were in Brazil, 11 per cent in Argentina, 11 per cent en Bolivia, eight per cent in Paraguay (UNEP, 2000). In 1999-2000, the total number of incidents dropped by 29 per cent in the South American countries monitored. Although there was a decrease in Brazil, there were increases in Colombia and Venezuela. In general, human activity causes forest fires through land clearing, agriculture and hunting, but they are also due to earlier fires, bonfires and burning litter (Cochrane, 2002). Fragmentation following deforestation and a change in soil cover exposes the forest to more fires and increases the risk of accidental fires. Forest fires have significant sanitary, economic and environmental effects. Smoke causes cardiovascular and eye problems, as well as constrictive and obstructive pulmonary illnesses, asthma, pneumonia, bronchitis, acute laryngitis and bronchiectasis (Cochrane, 2002). At local level, environmental effects include soil degradation, an increase in the risk of flooding in the rainy season and of drought when there is no rainfall, a reduction in animal and plant varieties, and a greater possibility of recurrent fires. At world level, these effects include the release of greenhouse effect gases, a reduction in precipitation and the extinction of the animal and plant populations. No estimates have been made of the broad spectrum of effects mentioned here when assessing the economic impact of forest fires. However, in 1998 when fires destroyed at least 9.2 million ha throughout the region, estimates of damage ranged from US$10-15,000 million (Cochrane, 2002).

Impact of deforestation While over the past 30 years the extraction of fibre from natural forests and plantations has practically doubled in the region, it has been at the cost of other forestry goods and services. To begin with, a reduction in forest cover tends to cause deterioration in the amount and quality of water resources, and there is increased soil erosion and sedimentation of water courses. But perhaps the greatest evident impact is on biodiversity goods and services affected by the increase in the number of endangered species, the conversion and fragmentation of forest habitats, the extraction of wood and the introduction of exotic species. To all these is added a reduced carbon fixing potential as a consequence of deforestation and soil deterioration (FAO, 2001a). These effects – which represent a permanent loss of the potential capacity of forest resources to provide economic benefits (IDB, UNDP, ACT, 1992) – are more severe in some countries than in others. In the Caribbean, for example, imported forestry products represent 14.2 per cent of total consumption. Although it has dropped from a maximum of 22.8 per cent in 1984, this figure is much higher than in Mesoamerica (2.6 per cent and growing) or South America (0.3 per cent and decreasing) (FAO, 2002a). The high consumer imports into the Caribbean are mostly of sawnwood and wood panels (imported to meet about 80 and 60 per cent, respectively, of total consumption).

In countries with large extensions of forests like Brazil, deforestation has had fewer general effects although local effects may be important. In the past two decades, wood production in Brazilian Amazon has increased from 14 to 85 per cent of national production, 80 per cent of which is estimated to be illegal (UNEP, 2000). The southern states of Brazil import hard woods from the northern states and from Paraguay where most of the remaining forests are protected (Tomaselli, 2001).

Forest policies As a response to deforestation problems, degradation of forests and forest fires, some countries have adopted new forestry laws and policies that include better regulatory measures, sustainability principles, expanding protected areas, certifying forestry products and expanding forest plantations in non-forest areas. These countries include Argentina, Brazil, Costa Rica and Peru (BOLFOR and others, 1998; Gobierno de Perú, 2000; Tomaselli, 2000). Laws passed in the 1990s contemplate fiscal and economic instruments such as certification to promote sustainable management of natural forests and forest plantations. Countries with new legislation include Mexico (1992, 1997), Bolivia, Costa Rica and Guatemala (1996), and Cuba (1998) (Brañes, 2001). In some countries, the response to deforestation has combined

development based on forest resources with regulation of forest activities, recognising that policy and institutional aspects are often more important market factors in determining the rhythm and effects of deforestation (Kaimowitz, 1997). Bolivia’s new forestry law, for instance, places forest land at the disposal of private companies by awarding concessions and involving local and indigenous communities (Tomaselli, 2000). Managed forest areas represent 3.8 per cent of total forest cover (FAO, 2001e). These areas, listed in descending order, are in: Mexico (7.1 million ha); Bolivia (6.9 million); Guyana (4.2 million); Brazil (four million); Venezuela (3.9 million); and Paraguay (three million). More than two million ha have been certified by the Forest Stewardship Council (FSC), an organisation with headquarters in Oaxaca, Mexico (FAO, 2001e). The FSC awards certificates to logging operations that comply with resource management standards, the fair distribution of benefits and environmental protection. As shown by the case of Mesoamerica during the 1990s, this has brought a boom in associative enterprises (cooperatives, community companies) that capitalise on agroforestry traditions to enter new markets.

Protected forests in South America occupy almost 123 million ha, or 19.5 per cent of the remaining world forests, and 62.15 per cent of the total protected areas (UNEP, 2001). This region still has vast tracts of intact tropical and temperate forest, including those in the northern Andes, which is one of the world’s richest biological zones. As indicated above, planted trees cover 1.2 per cent of the region’s forest surface for a total of 11.7 million ha (FAO, 2001a, 2001e). These plantations are concentrated in Brazil (five million ha) and Chile (two million), followed, in descending order, by Argentina, Venezuela, Peru, Uruguay, Cuba and Mexico which, together, have a total of 3.8 million ha. In general, they are industrial exotic species plantations (mainly eucalyptus and pine). These plantations will grow in size and economic importance as commercially-exploitable forests shrink, and by using more sustainable silviculture techniques, although there serious institutional and private sector weaknesses still limit their expansion. Although the plantations are being converted into an economic alternative to other soil uses (such as agriculture) and, thus, help to reduce deforestation, they always imply a loss

Payment for environmental services in Costa Rica In Costa Rica, the concept of payment for environmental services (PSA) is based on the principle that the proprietors of forests and forestry plantations have a right to compensation for the cost of preserving or restoring the benefits such ecosystems bring to the country and to the rest of the planet. According to the Forestry Law of 1996, these services include reducing, absorbing, fixing and storing carbon to lessen the greenhouse effect; protecting water for urban, rural or hydropower use; protecting ecosystems to conserve them and make them fit for sustainable use (scientific, pharmaceutical and genetic improvement); protecting ecosystems, forms of life and scenic natural beauty for tourism and scientific purposes. Since 1997 Costa Rica has applied a programme of payment for environmental services in 5 per cent of the national territory (more than 260,000 ha and 22,000 small and medium-sised properties); 85 per cent of the area consists of protected private forests and more than 9 per cent is under sustainable forest management for wood production. While in the period 1979-1995, reforestation accounted for 76 per cent of forestry incentives, from 1997-2000 this activity only received 7 per cent of the payments for environmental services. In 2001, the PSA received 5,412 million colons (about US$16.5 million) from fuel and hydrocarbon consumption taxes; the Tax Simplification and Efficiency Law of that year allocated a fixed amount of 3.5 per cent of such taxes to be paid to the programme. Other funds come from the sale of environmental services both nationally and internationally, including new experiments such as the municipal water tariff of the Heredia Public Services Company and the emission reduction certificates for renewable energy projects within the framework of the Kyoto Protocol (see sections on Freshwater and Atmosphere) The programme is administered by the Ministry of Finance which collects the resources, and the Ministry of the Environment and Energy (MINAE), which executes it through the National Conservation Areas System (SINAC) and the National Forest Financing Fund (FONAFIFO). Funds provided by the Ministry of Finance and other financing sources are administered by FONAFIFO. Requests by interested parties are processed by SINAC, which approves payments through conservation areas and each year determines the priority areas where the programme is to be applied.

of existing biodiversity in natural forests (Cavelier and Santos, 1999; FAO, 2001a). Experience with incentives and payment for environmental services, and other innovative financing schemes in the region, has shown the long-term feasibility of managing forest resources to be an excellent renewable resource (UNOFOC and others, 2000). In 1996, for example, Costa Rica established a mechanism in its Forestry Law for economic compensation for services provided by forests and forestry plantations. This has been a source of additional financing for several protected areas and in the practical implementation of many of the precepts of the Clean Development Mechanism in the Kyoto Protocol (1997) (State of the Nation Project, 2001; see Chapter Three). Other countries, including Chile, El Salvador, Guatemala and Honduras, are exploring options to develop similar mechanisms (Rosa and others, 1999). Most governments receive international help in formulating environmental policies to address deforestation problems, strengthening institutions and establishing structures and mechanisms to improve monitoring and control. In general, the programmes and projects which are given international support are related to world concerns such as the conservation of biodiversity

and global warming. Silviculture programmes and projects with international support include the BOLFOR Project in Bolivia, the PPG 7 (Pilot Project to Conservation Tropical Brazilian Forests) in Brazil and the Iwokrama Project in Guyana. International organisations such as FAO and ITTO are active in the region. One of the challenges to forest policies in the region is the lack of recognition that the knowledge belonging to people living in forests can be protected by biodiversity patents. It is also necessary to develop sustainable logging practices that affect wood-yielding and non-wood yielding products. Ecotourism and recreation are particularly promising as a non-consumer use of forest resources. In spite of the efforts to respond to deforestation, and notwithstanding positive responses in recent years, most countries in the region have not faced up to the problem’s root causes. They do not yet implement policies that would effectively reduce deforestation by ensuring compliance with forestry laws and regulations. In particular, urgent and efficient measures are needed to put a stop to corruption in implementing laws. Demographic and economic pressure on agricultural land and human settlements often leads to overexploi-

Forest policy: the international framework The United Nations Conference on the Environment and Development (Rio de Janeiro, 1992) ended with the declaration of a set of forestry principles and a chapter in Agenda 21 on policies against deforestation. This led to a suggestion for a global-scale forest sustainability regulation. Following the Rio conference, forest policies became the subject of international discussion, first of all within the framework of the Intergovernmental Panel on Forests (IPF), and then of the Inter-governmental Forest Forum (IFF). These negotiations led to the creation in 2000 of the United Nations Forum on Forests. The work of the IPF-IFF produced proposals to be executed by the new Forum on Forests. These include the development of national forestry and land use plans; emphasis on the underlying causes of deforestation; the promotion and protection of traditional knowledge on forests; the assessment of forestry goods and services; the development of adequate institutional and legal mechanisms (among them the possibility of an international convention on forests); as well as financial matters and technology transfer. Another proposal was to prepare criteria for sustainable forestry regulation to allow more specific parameters to be established on the subject, and regional and sub-regional initiatives have been developed throughout the world. In general, Latin American and Caribbean countries have adhered to the three initiatives named after the places where they originated (FAO, 2001e): Tarapoto (in South America), Lepaterique (in Central America) and Montreal (Mexico, Argentina, Venezuela and Uruguay, here coinciding with Canada and the United States). An important focus of international debate in the Forum on Forests is the harmonisation of guidelines relating to forestry in the three conventions resulting from the Rio conference biological diversity, combat against desertification, climate change as well as other relevant multilateral agreements, such as the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and the Ramsar Convention on Wetlands.

Towards owards sustainable management of natural forests Among the principal subjects emerging from the discussion on forests is the concern for the loss of the region's natural forests –with their biodiversity and associated environmental functions– and the sustainable management of natural formations. Most countries provide incentives for managing their native forests: exemption from land taxes (Chile, Ecuador, Uruguay), technical assistance (Ecuador), subsidies (Argentina, Mexico, Colombia) or payment for environmental services (Costa Rica). In addition, most countries are demanding prior management plans and place limitations on changes in forest land use. Some countries demand prior studies on environmental impact before approving forestry projects of any importance (Chile, Guyana), while others are already applying forestry certification (Mexico, Belize, Costa Rica, Brazil). A positive initiative by some countries –for example, Argentina, Chile, Paraguay, Costa Rica and Mexico– is the establishment of model forests designed to demonstrate the application of sustainable management, taking into account productive and environmental aspects, and with wide participation by civil society, including community and indigenous groups. In Cuba, the creation of integrated forest farms has had notable success in rehabilitating vegetation in the Cauto basin (CIGEA, 2001; Granma Internacional, 2002). Sustainable forest management, taking into account all the elements involved, requires an enormous research effort, especially on how the region's complex natural forestry ecosystems function. However, regional forestry research is clearly deficient in this respect and in most countries concentrates on matters related to the establishment, management and utilisation of forest plantations, usually with introduced species.

Diversity of ecosystems and species

Biodiversity

B

iodiversity refers to the variability among all living organisms, on three basic levels: ecosystems, species and genes. The biodiversity of a country or a region in the world, marine or terrestrial, is reflected in the different types of ecosystems, the number of species, how species vary between one location and another and the number of endemisms, as well as subspecies and varieties or strains of the same species (UNEP, 2002). Latin America and the Caribbean contain an exceptional variety of species and genetic varieties, as well as ecosystems. This biological wealth is undoubtedly one of the region’s main assets, and its loss, one of its principal environmental problems. The greatest challenges are irreversible habitat loss or change, extinction, loss of genetic diversity, introduction of exotic species that damage native species, fragmentation of ecosystems and trade in endangered species.

The principal ecosystems in Latin America and the Caribbean, according to size (Dinerstein and others, 1995): ·

Broadleaf tropical forests, humid and dry(9.3 million km3; 42.8 per cent of the region’s territory).

·

Grassland (floodplains or montane), shrub and savannah (7.1 million km3 - 40.6 per cent of the territory).

·

Mediterranean shrub or chaparral and deserts (1.9 million km3; 11.5 per cent of the territory).

·

Temperate broadleaf forests and tropical or sub-tropical conifer forests (1.1 million km3; 5.1 per cent of the territory).

·

Mangroves (0.2 per cent of the territory).

Endemism hot spots in Latin America and the Caribbean Worldwide, 25 endemism hot spots have been identified by their exceptional concentration of endemic vascular plants (at least 0.5 per cent of the world total), and because they suffer an exceptional loss of habitats (more than 70 per cent of their primary vegetation) (Myers and others, 2000). Vascular plants were selected as a guide because they have the best known taxonomy and form the basis for much of animal life. Together, the 25 hot spots contain more than 44 per cent of the world's vascular plants. The seven in Latin America and the Caribbean, which together have 16.2 per cent of the world's known endemic plants and 17.0 per cent of it vertebrates, are: the whole of Mesoamerica, the Caribbean, the Chocó-Darién region and western Ecuador, the Atlantic forests, the savannah of the Brazilian Cerrado, the tropical Andes, and central Chile. The variety and density of endemic species in these areas are a reflection of how biology has evolved in the Neotropics. Together, these hot spots harbour more than 46,000 vascular plants, 1,597 amphibians, 1,208 reptiles, 1,267 birds and 575 mammals, all endemic. Because it is insular, the Caribbean shows a high level of endemism, with 23.5 endemic plants for each 2 100 km , surpassing by 3, 4 and 12 times, respectively, the density in the Remaning % of Number of primary % of Brazilian Atlantic forest, the tropical Endemic endemic vegetation remaining ENDEMISM world Andes and Mesoamerica. protected plants HOT SPOTS

Although this is recognized as a useful tool to prioritize global conservation areas in situ, even its advocates confess that it excludes areas that may be important not only regionally or sub-regionally, but also globally. For example, Amazon is not one of the hot spots suggested by Myers and others (2000), not so much because it is not an important world biological diversity reserve, but because it does not have the loss of primary vegetation to be considered as such.

The principal ecosystems may be subdivided into large habitat types (biomass) and ecoregions (relatively well-defined units within the biomass); 178 ecoregions have been identified in Latin America and the Caribbean (Dinerstein and others, 1995; Olson and others, 2001). It is estimated that these ecosystems contain more than 40 per cent of the world’s vegetable and animal species (UNEP, 2000). Freshwater fish is a particularly good example of this wealth (WRI, 2000a). While North America has some 500 and Europe 150 fish species, some researchers estimate that Amazon harbours close to 2,500 species, or half the world’s total, although many ·

total

have still not been described scientifically. This diversity makes the Amazon region the richest deposit of freshwater fish in the world (Zimmerman, 1997). In Brazil, Colombia, Ecuador, Mexico, Peru and Venezuela, 190,000 of the world’s 300,000 known vascular plants have been identified (a third of the world total are in Brazil and Colombia) (Mittermeier and others, 1999). These six countries are part of the group of nations that, worldwide, has been identified as having biological megadiversity; together, they harbour between 60 and 70 per cent of all forms of life (CONABIO, 1998; CCAD, 2003). Their topography, climate variety, geology and biology have contributed to a mosaic of

Chapter 2: State of the Environment in Latin America and the Caribbean, 1972-2002

Environment Outlook

many and diverse small-scale environmental conditions that support a large variety of habitats and life forms. Brazil is the country in the region with most species (57,704 species of plants, fish, amphibians, reptiles, birds and mammals), but some small Central American countries and Caribbean islands - Belize, Costa Rica, El Salvador, Haiti, Jamaica, Panama and Trinidad and Tobago (WRI, 2000b) - also have a high density. In Panama 732 bird species have been identified and in Costa Rica 600; there are 100 species of mammals known in Trinidad and Tobago and 3,308 plant species in Jamaica (WRI, 2000b). Endemism is the term for species that are only found naturally in a specific territory. Several countries and territories in Latin America and the Caribbean are distinguished not only because of the variety of their species but also for their high rate of endemism. Of the vascular plant species identified in Brazil, Colombia, Ecuador, Mexico, Peru and Venezuela, 37 per cent are endemic (Mittermeier and others, 1999). In the region, Mexico is outstanding in this respect; of 704 species of reptiles, 393 are endemic (56 per cent), 179 of 282 species of amphibians (62 per cent) and 139 of 439 species of mammals (32 per cent) (INE, 1995). The endemism of the tropical Andes (in Venezuela, Colombia, Ecuador, Peru, Bolivia, the northeast of Chile, Paraguay

and the northeast of Argentina) and its great habitat losses (Myers and others, 2000) has made this place the world’s principal biodiversity hot spot.

Genetic resources diversity Genetic diversity, variations between the genes of individuals in a species, is the basis for evolutionary processes. Individual genetic differences determine different capacities to adapt to the environment; this explains why some individuals develop characteristics that allow them to adapt to the environment while others do not, and disappear. High levels of genetic diversity allow species to adapt to environmental changes, while low levels make it more likely they will become extinct (SCBD, 2001). An awareness of genetic diversity is an essential tool to satisfy basic human needs. Agricultural species are a reserve of genetic adaptability, and their loss endangers global food security when unforeseen environmental and economic changes occur (FAO, 2002; MMABI, 2002). Twenty-five per cent of the international pharmaceutical market consists of products based on biological material and, in 1999, world sales of products derived from traditional medicines reached US$4,300 million (WIPO, 1999).

Bioprospection and intellectual property: the conflict for frogs and analgesics in Ecuador The search for substances that control or eliminate pain must be as old as medicine itself, and with the passage of time it was discovered that an analgesic could have severe side effects, such as addiction to the drug. There can also be ecological and legal effects, as has been so well demonstrated by ABT-594, an analgesic derived from epibatidine, which is said to be 200 times more powerful than morphine. It is a compound of various substances extracted from the skin of a poisonous frog of the Latin American tropics (Epipedobates tricolor), and its habitat stretches from the Ecuadorian Andes to the north of Peru. Indigenous inhabitants in Ecuador poison the arrows of their blowpipes with this substance which has a very quick effect when it enters the hunted animal's circulatory system. The cause of the conflict is two-fold: appropriation of intellectual property and smuggling of a species of wildlife. As to intellectual property, the production of the analgesic is based on information on the physiological effects of the secretions which is the property of the indigenous and local communities. The discovery required trials with 750 frogs smuggled out of the country. This smuggling was exacerbated because this is the very species whose use as a source of genetic resources is prohibited by the Ecuadorian Forestry and Natural Areas Institute, a prohibition that has been in force since 1996. Ecuador has been a party to the Convention on International Trade in Endangered Species of Wild Flora and Fauna (CITES) since 1975, so that the export and use of these frogs for commercial purposes requires a special licence that the manufacturer of the analgesic did not request. When it became public that the substance was being patented in the United States, and based on the Convention on Biological Diversity and on Ecuadorian laws, the Ecological Action Group requested that the patent be revoked, and that the benefits from the synthesized products be recognized and “shared fairly and equitably“.

Latin America and the Caribbean

Although some countries and indigenous communities have been using and protecting this biodiversity for thousands of years, they have so far derived very little benefit from it. Through a process recently described as biopiracy, private companies in developed countries take advantage of these communities’ knowledge and genetic resources, and exercise monopolistic control over them by means of patents or plant reproduction rights (CIPR, 2002). The resulting products sell for high prices in their domestic markets and in markets in developing countries, and provide continuous profits.

Threats to biodiversity Physical changes and habitat pollution, as well as direct damage to organisms, are among the main threats to biodiversity in the region. Changes in habitats are caused by excessive harvesting of renewable resources (water and forests, for example), mining, extraction of petroleum, infrastructure construction in coastal zones, forest fires, expansion of agriculture and raising livestock. Pollution comes from agrochemical products, urban and industrial waste, and sewage. Finally, the introduction of exotic species and illegal wildlife trade directly affects organisms.

Converting habitats Regions with their own climates, flora and fauna, like the Chaco or the Cerrado, are called ecoregions. As a result of conversion and loss of habitats, 31 of 178 ecoregions in Latin America and the Caribbean are critically endangered, 51 are endangered and 55 are vulnerable. Together these represent 77 per cent of the total (Dinerstein and others, 1995). Only 4.5 per cent of the ecoregions can be defined as relatively intact. A significant number of ecoregions are critically endangered or endangered in northern Mexico, Central America, the Caribbean, the northern Andes and eastern South America. There have been very serious changes in habitats in Central American forests, the Chaco, the savannah ecosystems of the Brazilian Cerrado, the Mediterraneantype shrub of the Pacific coast and the Brazilian Atlantic coast forests (Dinerstein and others 1995; Mittermeier and others, 1999). For example, the Cerrado — Brazil’s second largest biomass after the Amazon rainforest — that covers approximately two million square kilometres, was mainly used for extensive cattle raising until 40 years ago. Now nearly 47 per cent of its natural vegetation has been converted into grassland, cropland, dams, urban settlements and degraded areas. The main cash crops – besides grassland – are soybeans, maize, rice, coffee and beans. Only one per cent of the Cerrado is under any type of protection (Klink and others, 1995).

82.7 million hectares (ha) in 1990 to 73million ha in 2000 (almost 971 000 ha of forests annually), with a deforestation rate of 1.25 per cent annually — the highest in the region, and almost six times the global rate (FAO, 2000). The biggest losses were in Mexico (6.3 million ha) and Nicaragua (1.2 million ha); Belize, Nicaragua and El Salvador suffered the greatest relative losses of, respectively, about 20.9 and 37.3 per cent of the 1990 forest cover. The conversion and loss of habitats have a direct impact on the vulnerability and extinction of the species they contain. For example, critical sites in Mexico where almost half of all migratory birds (Hernández and others, 2000) take refuge during the northern hemisphere’s winter are endangered by pollution, deforestation and other land use changes (UNEP, 2000; de Alba, 2001).

Species threatened or endangered with extinction Most of the species endangered or threatened with extinction are found in countries with the most biodiversity, including Mexico, Brazil, Colombia, Ecuador and Peru. Four of these countries —Brazil, Colombia, Peru and Mexico— harbour more than 75 per cent of the continent’s endangered bird species (BirdLife International, 2000). Between 1996 and 2000 the total number of endangered animal species grew from four per cent in Mexico and Peru to 10 per cent in Ecuador, 11 per cent in Colombia and 13 per cent in Brazil (Hilton-Taylor, 2000). In Peru alone, the number of threatened or endangered species rose from 162 in 1990 to 222 in 1999 (CONAM, PNUMA, 2001). However, the degree of danger varies: 12 per cent are in danger of actual extinction, 21 per cent are “vulnerable”, 27 per cent are classified as “scarce species” and no determination has been made about the remaining 40 per cent (CONAM, PNUMA, 2001). In Costa Rica, another country in the megadiverse group, barely two per cent of known species are endangered or threatened with extinction, but the situation is becoming alarming in the case of freshwater fish: practically all 135 known species are endangered to a greater or lesser extent (MINAE, PNUMA, 2001). Mexico accounts for 5.2 per cent of the species extinguished worldwide over the past 400 years: 15 species of plants and 32 species of vertebrates (CONABIO, 1998). The sea cow (Phocoena sinus), for example, is now only found in the northern part of the Gulf of California. It is estimated that in 1997 only 567 remained, mainly due to accidental fishing - it can be confused with fish or gets caught in shrimp nets (WWF, 2003b).

Latin America and the Caribbean

Trade in species Judging only by declared import values, probably underestimated, world trade in wild animals and plants (alive or as products), amounts to about US$159,000 million annually (Cook and others, 2002). It has been calculated that a quarter of this trade is illegal, making it the second largest illegal trade in the world, after drugs (WWF, 2003a). The value of the animal, which rarely is more than US$200 in the country of origin, may easily reach US$10,000 on the international market. One tordo chaqueño (charrúa, guira-hú or melro) bird, Gnorimopsar chopi, may be bought in southern Brazil for US$150 but, once in the United States, it sells for US$13,000. A tamarind monkey or golden-headed tití, Leontopithecus chrysomelas, is worth US$180 in Brazil and US$1,500 in Europe (Ecoportal, 2002). Countries in Latin America and the Caribbean are among the biggest exporters of wild organisms to consumer countries, especially the United States and the European Union (Cook and others, 2002). One estimate suggests that South America provides 47 per cent of animals illegally captured in the world; 37 per cent come from Brazil, the country with the world’s greatest biodiversity, and the rest from Peru, Argentina, Venezuela, Paraguay, Bolivia and Colombia (Ecoportal, 2002). It is estimated that illegal trade from Brazil represents an annual value of US$1,000 million, a tenth of the world total (UNEP, 2002). In Mexico, at least one of each five wildlife export cargoes checked by Customs in April 2002 was illegal, according to the Federal Attorney General’s Office for Environmental Protection (Ecoportal, 2002). Approximately half the cactus native to the Chihuahua desert in Mexico and confiscated in Europe and the United States, are protected from international trade by CITES (Robbins, 2003). In Colombia, smuggled organisms are sent to large cities and neighbouring Amazon countries, whence they are re-exported (MMA, 2000). In 2001, specimens protected by international conventions and worth almost five million US dollars were illegally traded in Chile; the main sources are in Peru and Bolivia, countries popular among traffickers because of their rich biodiversity. The number of organisms confiscated in a year suggests that, worldwide, vertebrates and plants are the main victims of illegal trade (Cook and others, 2002): primates (230,000), wild plants (1.1 million), live birds (1.1 million) and live reptiles (3.7 million). The pattern is not necessarily the same throughout the region. In Colombia, for example, confiscations indicate the following percentages of animal groups: birds (44.6 per cent), mammals (31.0 per cent), reptiles (16.8 per cent), fish (0.5 per cent) and crustaceans (0.1 per cent). A large number of mammals are primate and feline species, all considered to be critically endangered. Live examples ·

represent between 80 and 95 per cent, but there is also trafficking in stuffed animals, skins and various other products (MMA, 2000).

Introduction of exotic species Human beings can also dramatically change the distribution of species in an ecosystem. The introduction, by accident or design, of exotic organisms, has intensified with the boom in sea and air transport all over the world. Invading exotic species do not always manage to establish themselves immediately, but their populations could eventually explode and threaten ecosystems, habitats and native species (UICN, SSC, 2000), as changes in ecosystems make conditions favourable. In Latin America and the Caribbean examples include the introduction into freshwater ecosystems of exotic fishes mainly linked to aquaculture such as tilapia or trout. Invasion by aquatic plants such as water hyacinth and tifa has been detected in some wetlands. The problem is more marked in islands and isolated ecosystems like cloud forests, coastal habitats, high mountains, lakes and lagoons (UICN, SSC, 2000).

Genetic impoverishment of domestic species Human food comes from plants and domestic animals, although in some places fishing and other wild sources play an important role. The principal domestic species originated in areas with a high degree of biodiversity, ecologically varied (almost all mountainous zones) and with more advanced and diversified cultures. For example, two of the six hypothetical centres of origin of the principal cultivated plants are in Latin America and the Caribbean (FAO, 2002). Human beings have used thousands of species for food over many thousands of years, and domesticated a large number of them, but we now see genetic impoverishment because only relatively few are cultivated or bred. The impressive number of varieties of maize cultivated by the ancient Mexicans, as well as many varieties of potato that used to be seen in Andean markets, are long gone. At the beginning of the 21st century, only 150 vegetable species were cultivated, and only four produce more than half the food for human consumption (FAO, 2002; Sarukhán, 2002). The same applies to animals: of the 50,000 known species of mammals and birds, only some 30 have been widely bred and 15 account for more than 90 per cent of world livestock production. In the past 15 years, 300 of the 6,000 livestock species defined by FAO have been extinguished. At present, 1,350 of these species run the risk of extinction, and an average of two species disappear every week. Selection means that very few domesticated organisms, whether plants or animals, can still survive in nature without human intervention (FAO, 2002). There is

Chapter 2: State of the Environment in Latin America and the Caribbean, 1972-2002

Environment Outlook

a natural, and very important, reason why genetic impoverishment must be prevented: to maintain the evolutionary potential of species and, thus, their capacity to adapt and survive (CONABIO, 1998). Similarly, mixed crops may provide better harvests because their genetic variety acts as a barrier against diseases and predators. Genetic impoverishment is indirectly associated with the relationship between international trade in agricultural products and the sustainability of the environment. Increasingly impoverished domesticated biodiversity earns more profits than wild biodiversity. However, both types require investment to resist, for example, a mutant virus which (because of a lack of genetic variability) could deal a severe blow to the dairy industry by finishing off a variety of dairy cattle The wild relatives of cattle and other domestic varieties make up the genetic reservoir that could prevent this. Domestic and wild varieties need to be kept in a delicate balance between facilitating trade and conserving biodiversity.

Transgenetic contamination Genetic diversity is the basis of biotechnology, particularly in the case of genetic engineering, which is generating great changes in agriculture, industry, medicine and even legislation (Munich Re Group, 2002). However, taking biotechnological advantage of natural diversity may eventually endanger it through “genetic contamination”. Natural genes pass uncontrolled from one species to another with no problem. That modified genes might do so is a real risk. The possible transgenetic contamination of Mexican maize is a good example of this con-

cern about the intromission of modified genes into domestic varieties and their wild relatives. One of the main dangers is that intromission would affect their characteristics, placing in danger a biodiversity essential for humanity’s food security. In Mexican maize fields in the remote mountains of Oaxaca, pieces of DNA produced by genetic engineering were detected (Quist and Chapela, 2001). The study was attacked with the argument that it was the result of a biased test and a misinterpretation of the literature (Metz and Fütterer, 2002), an accusation denied by the authors of the original study (Quist and Chapela, 2002). Although the debate continues (Aldhous, 2002), a cause for concern is the lack of cooperation from transnational companies that dominate the market (on the pretext of trade secrets) ; indeed, an attempt was made to disallow the study just before a meeting of the Convention on Biological Diversity (The Hague, Netherlands, 8-26 April 2002). There is a widely-held belief among geneticists and plant improvement specialists that contamination of traditional crops is inevitable (AGETC, 2002; ISIS, 2002; Pearce, 2002). Mexico’s National Commission on Biodiversity Knowledge and Use has reported that two independent studies found large-scale contamination in varieties of maize planted close to highways (ISIS, 2002; Pearce, 2002). Apart from the possible environmental consequences of transgenetic pollution, this causes concern about the medium- and long-term effects of genetically modified food on human health. Again, this debate polarises positions and touches on large commercial interests; until there is scientific consensus on the subject, precaution is advisable (Butler, 2002).

Dangers of introducing new species to the islands Implicit in human occupation of a region is the transfer of plants and animals, which often become established in the new territories. Almost always the introduction of species to new zones is uncontrolled and may produce serious alterations in ecosystems. When the new territories are islands, the consequences are even worse because, in most cases, there are no natural predators that control the growth of the introduced populations. Also, due to the isolation in which they have evolved, island species have not developed the defence mechanisms they need and are very vulnerable to attack by new predators. Furthermore, island species generally have low reproduction rates and long life cycles, so that their populations are smaller than continental populations and it is more probable that they will become extinct. There is a serious problem with fauna introduced to the islands: it is calculated that 75 per cent of the 484 species registered as extinct in the world since the 17th century were species endemic to islands and that 67 per cent of the extinctions are totally or partially due to introduced species. An example of this danger is Isabel Island, off the coast of the state of Nayarit in Mexico, where rats and cats were 2 introduced more than 80 years ago. The density of cats is now one of the highest, 113 cats per km , of any island in the world and they have had a serious impact on bird populations. Of the various bird species that nest on the island, an endemic tern (Stena fuscata), is the most affected; because it nests on the ground it is easy prey for the animals so that, in the absence of control measures, it has a an uncertain future.

Domesticating and breeding Paca (Agouti paca) Paca or tepezcuinte (Agouti paca), is a rodent found from Mexico to Paraguay and the southern part of Brazil, usually in woody areas close to freshwater. It lives in burrows in the ground and rests during the day to become active at night time when it goes in search of small plants, fruit and seeds. As it weighs up to 12 kg and its meat has an excellent taste, it is a good candidate for domestication. It has been suggested that its meat be used to feed rural populations which, for one reason or another, are unable to keep larger animals. Normally it is hunted for its meat; this has affected wild populations and led to the establishment of experimental captive breeding programmes in countries such as Costa Rica and Panama. It is hard to breed tepezcuintes: they form monogamous couples that reproduce slowly, are aggressive in defence of their territory and, therefore, do not tolerate overcrowding, and there are cases of cannibalism and infanticide. By being aware of how the young learn, Panama has been able to achieve an artificial tolerance to captive conditions. In Costa Rica, this has been done successfully for several generations and has enabled veterinarians to learn more about the animals; the cost of keeping them has taken an unexpected turn by selling the meat to luxury restaurants instead of using it as food for rural communities. Source: FAO, 1995.

Policy responses Responses range from national initiatives, generally connected to the establishment of protected areas, to the adoption of multilateral and regional environmental agreements which have recently stressed the subject of access to biodiversity resources. The establishment of new protected areas and better management of existing ones are among the most significant actions taken in the region to conserve biodiversity. There are 65 UNESCO-designated biosphere reserves in Latin America and the Caribbean, about 15 per cent of the global total of 411 reserves. In the last three decades of the 20th century, although the number of protected areas almost doubled, their extension only increased by 50 per cent, indicating a trend

to establish smaller areas. In the latter part of the 1990s, a total of 148 million ha of very varied ecosystems, classified under different management categories, received some type of protection (WRI, 2001); some countries have created extensive maritime-terrestrial protected areas, as Ecuador did with the Galapagos Islands. There are countries where a large proportion of the territory is protected, and Ecuador is again an example (42 per cent), followed by Venezuela (35 per cent), Belize (20 per cent) and Panama (18.8 per cent). In contrast, other countries in the region have a low proportion of protected territory: Jamaica (0.1 per cent), Haiti (0.3 per cent) and Uruguay (0.3 per cent) (WRI, 2000b; OdDUCR, PNUMA/ORPALC, 2001). In spite of advances in conservation in natural conditions (or in situ), this strategy needs to be perfected. In

Biotic inventory: a Caribbean necessity In the Caribbean, less than 10 per cent of original island vegetation is still intact. Worse still, only a part of that 10 per cent is protected by parks and reserves. As the small intact areas are generally found in the smaller islands, they are under greater pressure. In addition, the smaller the island, the more endemic species it has so that there is less margin for error in maintaining the biotic heritage of small islands than there is in preserving it in larger islands or on continents. To conserve and take advantage of this biotic heritage, an inventory is needed to identify existing resources. However, economic and conservation decisions are haphazard and pose a serious risk of errors and damage to the islands' heritage. Therefore, the need for a biotic inventory for the small Caribbean islands is urgent, in particular because the importance to global biodiversity of the species involved is out of proportion to the size of the islands. A recent analysis of vascular plants and biodiversity of land vertebrates classified these islands as one of the three locations whose biodiversity is most endangered, according to Mittermeier and others (1999).

general, national protected areas are still not representative, since they neither include the countries’ ecosystems nor protect all the organisms that need protecting. Also, as they are not connected, seasonal migration routes and the normal genetic flow between subpopulations and populations are often interrupted. Areas that have significant protection are often too small compared to actual needs, not only as to whether they are representative of the ecosystem, but in more organic aspects such as the minimum area required to maintain viable populations, especially in the case of predator vertebrates. To the problems of representation and size is added the sharp contrast between the legal situation of natural protected areas and their actual situation, so that – it is said – they are really fictitious areas that exist only on paper. However, a quantitative inventory of the efficiency of 93 protected areas in tropical countries, including Belize, Brazil, Colombia, Ecuador, Mexico, Paraguay and Peru, found that — in spite of their limitations — most parks are successful in preventing land being opened up and, to a lesser extent, are efficient in putting a brake on logging, hunting, fires and grazing (Bruner and others, 2001). Just as the problem of representation has been addressed by increasing protected areas, an attempt is being made to link them by establishing biological corridors. These corridors are the result of new trends that favour protecting the whole ecosystem and integrating protected areas and agricultural, forestry and pasture land. Thus, people who live in or close to protected areas may join in conservation efforts by encouraging the restoration of the landscape and the maintenance of environmental goods and services. Biological corridors connect fragments of natural and managed forests so that fauna can move between them; this helps to keep their populations viable by preventing the in-breeding that can lead to genetic defects. Various corridors have been proposed and others are already in existence, such as the Mesoamerican Biological Corridor and the Amazon/Andes interface in the south of Peru and adjacent parts of Bolivia. The Mesoamerican Biological Corridor is a system of land regulation that connects buffer and multipleuse zones to the Central American Protected Areas System. It covers almost 30 per cent of Mesoamerican territory (including 19 per cent of Mexican territory) (CBM, 2001; OdD-UCR, 2003). It is expected to have a positive effect on problems like deforestation, forest fires, illegal hunting and fishing, indiscriminate extraction of basic natural resources and the fragmentation of the main protected areas in the eight Mesoamerican countries. In addition to strictly-protected areas, it includes restored ecosystems and private land whose proprietors will make voluntary ecofriendly use of the resources. The creation of the corridor was formally guaranteed by the Central American presidents (including the presi-

71

dents of Belize and Panama) at the Presidential Summit in Panama on 12 July 1997, and is a priority of the Central American Alliance for Sustainable Development. Its implementation is directed by the Central American Integration System in collaboration with the Government of Mexico and it receives international support (CBM, 2001). Buffer zones work with the corridors as a form of potentially important land regulation. They are spaces around the protected areas where only limited use is made of resources, because difficult access has prevented the market economy from penetrating. Whether legally constituted or not, buffer zones combine the objectives of conservation and sustainable use of resources. They may be attractive for future policies because it can be shown that they have contributed to the conservation of many renewable natural resources (Gierhake, 2002). Sustainable use of a resource has been demonstrated to be the best means of protecting and conserving it. It is therefore important to develop this biodiversity conservation component so that it can be incorporated in sustainable production processes. Experiments of this type are being fostered in various countries in the region, such as Brazil and Costa Rica.

The other important component in biodiversity environmental policies is the implementation of global, regional or sub-regional multilateral agreements. The implementation plan approved at the World Summit on Sustainable Development in Johannesburg (South Africa) in 2002 includes among its goals achieving, by 2010, a significant reduction in the present rate of biodiversity loss. This plan reflects concerns expressed in a great many multilateral environmental agreements (MEAs), with biodiversity at their heart. Among the principal MEAs in which the region is involved are the global conventions on: ·

the Convention on Wetlands of International Importance especially as Waterfowl Habitat (Ramsar), 1971;

·

the Convention on the Protection of World Cultural and Natural Heritage (World Heritage), 1972;

·

the Convention on the Conservation of Migratory Species of Wild Animals (CMS), 1979; and

·

the 1992 Convention on Biological Diversity (CBD).

There is also an important set of regional or subregional MEAs related to biodiversity. The most important of these is the Convention on the Protection of Flora, Fauna and Natural Scenic Beauty in the Countries of the Americas (1940). Among the main sub-regional agreements are ·

the Convention on the Conservation and Management of Vicuña (1979),

·

the Convention on the Protection of the Marine Environment and Coastal Areas of the south-eastern Pacific (1981),

·

the Cartagena Convention on the Protection and Development of the Marine Environment in the Greater Caribbean (1983) and its protocol on protected areas and wildlife (in force since 2000),

·

the Convention on the Conservation of Biological Diversity and the Protection of Priority Wildlife Areas in Central America (1992) and

·

the Central American Regional Convention on the Management and Conservation of Natural Forest Ecosystems and the Development of Forestry Plantations (1993).

Although ratification of global MEAs has been high in the region, with 75 per cent of the countries adhering to most of them (with the exception of the agreement on migratory species, which only a fifth of the countries have accepted), in practice their application differs from country to country. The CBD and CITES are of particular interest, because of the range of their cover.

·

The CBD, in particular, is considered to be a framework convention; it expresses a national and international commitment to the overall conservation and sustainable use of ecosystems, species and genetic resources, as well as fair and equitable participation in the benefits. In the region, the CBD or its objectives have been applied either by including it in general regulations (Brazil, Costa Rica, Peru and Venezuela), or by means of sectoral laws (Cuba, Costa Rica, Honduras, Mexico, Nicaragua and Panama). In 1994 Brazil established a National Programme on Biological Diversity. In Peru the Law on the Conservation and Sustainable Use of Biological Diversity, which entered into force in 1997, covers most of the commitments of the CBD. Between 1998 and 2000, Nicaragua, Guatemala, Panama and Mexico also completed their country studies and formulated national biodiversity strategies. Costa Rica and Venezuela have had laws on biological diversity since 1996 and 2000, respectively. It is hoped that the nine Caribbean countries now preparing national biodiversity strategies – Antigua and Barbuda, Belize, Dominica, Guyana, Jamaica, Saint Kitts and Nevis, Saint Lucia, Suriname and Trinidad and Tobago – will support the implementation of the CBD with legislation, clear institutional mechanisms and adequate resources (UNEP, 2000). Putting the CBD into practice depends to a great extent on national and international financing. This includes the biodiversity funds of agencies such as the World Bank, the IDB, other international organisations, the Global Environment Facility, non-governmental organizations and bilateral cooperation agencies. By February 2000, the GEF had supported seven regional and 84 national projects on biodiversity in Latin America and the Caribbean, all declared to be in tune with the goals and objectives of the CBD (GEF, 2000). As part of the mandate of the CBD, the Conference of the CBD Contracting Parties held a meeting in Cartagena, Colombia, in February 1999 on the subject of biosecurity, resulting in a signed protocol. After arduous negotiations, the CBD Protocol on Biosafety was adopted by consensus in January 2000 in Montreal, Canada and, in May 2000, was opened for signature in Nairobi, Kenya. It has already been signed by 60 countries and it will enter into force when ratified by 50 countries. The protocol will regulate transboundary movements of genetically-modified live organisms, with clear measures to prevent their intentional introduction into the environment. It will also protect traditional agriculture and wild fauna and flora species against genetically-modified organisms. The most controversial items in Cartagena and Montreal were the commercial aspects of applying the protocol, especially the demand (on the principle of prior informed consent) that products with modified live organisms be clearly labelled, and handled differently to those without them. It obliges exporting countries to

Regional action within the CITES framework The Convention on International Trade in Endangered Species of Wild Fauna y Flora (CITES) entered into force in 1975. To prevent international trade in certain excessively harvested species of flora and fauna, the convention established international prohibitions on endangered species (Appendix I), as well as regulations for those that might be endangered because of excessive or inappropriate trade (Appendix II). Appendix III lists species subject to national self-regulation and that require export permits from the regulating state and certificates of origin issued by other exporting states. At their biennial meetings, the parties review the list of species in each appendix and, by a two-thirds majority, decide which to include in Appendices I and II. Any contracting state may have reserves about one or several of the species included in these appendices, in which case they are considered as not being subject to regulations established for those particular species. At present, the lists include some 30 000 species, of which 25 000 are plants. More than 800 species of flora and fauna can be found in Appendix I, about 29 000 in Appendix II, and 230 in Appendix III. Two types of organisms in the region that have been paid particular attention within the framework of CITES are sea turtles in the Caribbean and mahogany in Mesoamerica and South America. In 1977, the parties to CITES agreed to prohibit international trade in the six species of Caribbean sea turtles, considered as under treat of extinction (three of them critically endangered) by the World Wildlife Fund. National compliance in the sub-region has differed widely, with high levels of concern, resources and compliance in some countries, but with very low levels in others. Only a third of the region's countries have ratified the InterAmerican Convention on Protection and Conservation of Sea Turtles (2001), the only international agreement in this field. It is estimated that Caribbean trade in sea turtles and their harvesting outside the sub-region continue, although they are dropping. Accidental catches predominate, above all because sea turtles are already so scarce that there is little profit to be had from catching them commercially.

Flow of big leafed mahogany

BOLIVIA In the case of mahogany (Swietenia out of Latin America and the macrophylla), the agreement to regulate its Caribbean (1997) international trade was adopted at the twelfth conference of the parties (COP-12), held in Chile in November 2002. The other two American species were already included although there is practically no trade in them because overharvesting has exhausted the supply. About 14 countries in the region export mahogany, mainly to North America and Europe. In 1998 the United States imported about 60 per cent of the total volume, which originated mainly in Brazil (45 per cent), Peru (31 per cent) and Bolivia (17 per cent).

In 1998 Brazil, the world's principal exporter of mahogany in that year, decided to include it in Appendix III of CITES, and in 2001 prohibited its logging and export; Bolivia, Costa Rica and Mexico have also included the species in that Appendix. Exports from Bolivia have dropped since it decided to restrict logging, while Peruvian exports have increased since the government gave concessions for it to be harvested in the Biabo-Cordillera Azul region. Until Nicaragua and Guatemala proposed including Appendix II in the COP-12, most illegal exports came from Brazil, Peru and Bolivia and, to a lesser extent, from Central America. There has been good experience in certifying sustainable harvesting of mahogany in Brazil, Guatemala, Honduras and Mexico, in the three last-mentioned countries under the auspices of the Forest Stewardship Council.

give prior information to importing countries about the characteristics of these organisms. This implies particular attention to strengthening institutional capacity to apply these new control functions, with a view to protecting wild aquatic, marine and agricultural biodiversity in the region. An additional aspect closely linked with the CBD, on which it is sought to establish agreements, is access to genetic resources and equitable benefit sharing. This is one of the subjects that have recently caused most debate about standards and public policies, both nationally and internationally. The ultimate objectives of the CBD include “fair sharing in benefits derived from the use of genetic resources”, through adequate access mechanisms. The International Treaty on Phytogenetic Resources for Food and Agriculture, approved in 2001, recognises the rights of farmers in centres of origin and

diversity based on their contribution to conservation, improvement and availability of resources. These rights include their participation in the adoption of decisions and the “fair and equitable” sharing of benefits (FAO, 2001). In February 2003, the treaty had been signed by 13 countries in the region although none of them had yet ratified it. However, various countries —including those of the Andean Community of Nations (CAN) — have already formalised many of its principles (SEMARNAT, 2002a). Guatemala, for example, has established its own protection systems for genetic resources, and uses them to protect intellectual property. The Andean countries (Bolivia, Colombia, Ecuador, Peru and Venezuela) have developed a common legislation within CAN, in 1996 approving Decision 391 on a Common Access to Genetic Resources Regime, making it the cornerstone for

National response initiatives: the cases of Colombia and Mexico Colombia and Mexico have had good experience in designing and implementing public policies, with private sector participation, on the conservation and sustainable use of biodiversity. In Colombia, the Green Markets Programme (PMV) seeks to respond to the world demand for “ecofriendly” products that has grown between 20 and 30 per cent annually (more than for traditional products). This is a good opportunity for countries with great environmental wealth to reduce the environmental impact of productive activities and generate resources that satisfy local development needs. The PMV was created by the Ministry of the Environment to provide incentives for the production of environmentally friendly goods and services or of sustainable production to compete in national and international markets. It is expected to provide self financing for activities that help protect the environment, and allow consumers to choose products that not only protect the environment, but are also healthier than traditional products. In Mexico, two notable initiatives have been developed in the field of biodiversity knowledge and awareness. In 1992 the National Commission on Biodiversity Knowledge and Use was created as an cross-sectoral commission whose main objectives were to: set up and maintain the National Biodiversity Information System; support projects and studies on awareness and use of biodiversity; provide advice to government institutions and to other sectors; undertake special projects; disseminate information about biological wealth; follow up on international conventions and provide services to the public. Outstanding among the commission's achievements are: the creation of the Mexican Biodiversity Information Network; the automated system to detect hot spots; the programme to conserve biodiversity priority regions; the preparation of the “BIOTIC” information management system; and the publication of more than 190 titles. The commission is also the scientific authority for CITES and the focal point for the Clearing House Mechanism, OSACTT, IGT and other groups of the Convention on Biological Diversity (CBD). In 1994 the Mexican Fund for the Conservation of Nature (FMCN) was established as a private civil association to conserve Mexico's biodiversity and promote the sustainable use of natural resources. The FMCN was capitalized with a contribution of US$10 million from the Mexican government and US$19.5 million from the United State International Development Agency. In 1997, the FMCN received a donation of US$16.5 million from the Global Environment Facility (GEF) to establish a fund to protect natural areas and it supports the management of 10 priority protected areas. These resources have permitted an additional US$14.5 million to be collected, including patrimonial contributions from the Mexican government and private foundations, for certain natural protected areas. A second GEF donation includes a project costing US$31.1 million, of which US$9.5 million of the patrimonial funds were spent in May 2002 on four additional natural protected areas.

national policies and norms on access to genetic resources and benefit sharing. Bolivia’s Superior Decree 24676 (1997) very specifically regulates Decision 391. Colombia and Venezuela, for their part, are applying the decision without additional norms or regulations. Ecuador and Peru are in the process of approving regulations on access to genetic resources. The Regional Biodiversity Strategy of CAN is designed to define guidelines and take joint action regarding access. Both CAN and Costa Rica require informed consent about the source before issuing intellectual property rights on genetic resources (CIPR, 2002). These initiatives will probably be reflected in much of the region’s future legislation.

In the region, and particularly in megadiverse countries, some of the obstacles to access to resources and benefits are: ·

vast genetic resources have already left those countries (for example, in botanical gardens and collections);

·

it is hard to enforce access regulations in one country if other countries do not have them (in cases where resources are shared or are in more than one country);

·

practical difficulties in controlling access;

Chapter

First Ministerial Meeting of Like-Minded Megadiverse Countries In February 2002 Mexico convened the first Ministerial Meeting of Like-Minded Megadiverse Countries. The meeting was attended by ministers of the environment from Brazil, China, Colombia, Costa Rica, Ecuador, India, Indonesia, Kenya, Peru, South Africa and Venezuela, to establish agreements on the conservation and sustainable use of biodiversity and to seek coordination mechanisms on environmental policy. An additional objective was to present a common front at the World Summit on Sustainable Development in Johannesburg. The meeting gave particular consideration to access to genetic resources and the fair distribution of benefits (including intellectual property and the respect and protection of traditional knowledge), the conservation and harvesting of biodiversity, biotechnology and bioprospection. Among the agreements reached –expressed in the Cancun Declaration– are the following: ·

To create the “Group of Like-Minded Megadiverse Countries” as a mechanism for consultation and cooperation to promote their interests and priorities related to the preservation and sustainable use of biological diversity to: coordinate efforts to present a common front at international fora dealing with biodiversity; promote in situ and ex situ conservation of biodiversity in the countries of origin; develop joint projects to make inventories of their resources; invest in the development and use of endogenous technologies to support local- level sustainable conservation of genetic materials and economic activities.

·

To ensure that the goods, services and benefits arising from the conservation and sustainable use of biological resources are utilized for the development of the populations, among other objectives seeking to improve food safety, solve health problems and preserve cultural integrity.

·

To jointly explore ways to exchange information and harmonize their respective national laws on the protection of biological diversity, including related knowledge as well as access to biological and genetic resources, and the sharing of benefits arising from their sustainable use.

·

To seek the creation of an international regime to effectively promote and safeguard the fair and equitable sharing of benefits arising from the use of biodiversity and its components.

·

To develop strategic projects and bilateral, regional and international agreements, within the framework of more effective South-South cooperation, for the conservation and sustainable use of biological diversity and genetic resources.

·

To encourage the current system of intellectual property rights to take into account traditional knowledge of biological diversity when evaluating requests for patents and other related rights.

·

To hold the first meeting of heads of state of the Group of Like-Minded Megadiverse Countries at the World Summit on Sustainable Development in Johannesburg, South Africa.

·

limited capacity to negotiate bioprospection projects;

·

lack of appropriate incentives to add value to resources within a country (and the passivity of national stakeholders);

·

difficulties in agreeing upon common positions in international negotiations;

·

pressure exercised by other negotiations (for example, the World Trade Organization); and

·

difficulties in effectively articulating the interests of indigenous communities.

To confront these obstacles, megadiverse countries in the region have begun policy and normative processes to legislate on the subject. At the same time, many academic institutions and private enterprises have adapted their access policies to the new reality of biological material. Access that was once free now requires, as a prior condition, information and transparency, negotiations on potential benefits, discussions on possible joint investments and the acceptance of other commitments with respect to each country’s norms, as well as the goodwill of the parties involved.

Latin America and the Caribbean

Freshwater

L

atin America and the Caribbean is a region rich in water resources. With only 15 per cent of the world’s land and 8.4 per cent of its population, it receives 29 per cent of total precipitation and has a third of the world’s renewable water resources (FAO, 2002). Despite this, there are marked differences in water availability throughout the region. Three of its principal water zones – the Gulf of Mexico, the South Brazilian Atlantic and the Paraná-Uruguay-La Plata Water basins – concentrate 40 per cent of the region’s population in 25 per cent of the territory with only 10 per cent of total water resources. Many areas in Mesoamerica, the Andes, the Brazilian northeast and the Caribbean suffer from recurrent or chronic water shortages (WWC, 2000). The region’s two most serious water problems are a reduction in available reserves and a drop in quality. Reserves are reduced because of deforestation, urban expansion and excessive use (due to population growth and agricultural and industrial demand). The drop in quality is caused by untreated sewage, excessive use of fertilisers and pesticides, and industrial, mining and energy pollution. There is a lack of awareness of the need to maintain ecological water flows (that is, the water needed for natural ecosystems’ other vital functions) or it is underestimated. If these trends continue, they could be a significant obstacle to sustainable development in Latin America and the Caribbean (ECLAC and UNEP, 2001). Of growing concern is the absence of integrated water management and laws to protect freshwater.

Availability of water resources and regional variations Of the world’s total supply of water, only 2.5 per cent or 35 million km3 is freshwater, almost all (close to 70 per cent) as polar ice caps. Of the remainder, most is found as soil humidity or in deposits too deep to be accessible for human consumption (some up to two kilometres below sea level - UNEP, 2002; SAMTAC, 2000). Freshwater recharge depends on evaporation and subsequent precipitation. Oceans are responsible for 80 per cent of water evaporation throughout the world, and only 20 per cent of precipitation falls on land. Usable water - representing less than one per cent of the planet’s existing freshwater - is found in lakes, rivers, soil humidity and relatively shallow groundwater deposits with recharge produced by run-off or seepage. Although this water is theoretically fit for use, it is found far from populated zones, so in fact it is difficult or even impossible to reach. ·

Present estimates are that the Latin America and Caribbean region receives an average of 1,556 mm of annual rainfall (equal to 31.8 km3), considerably more than any other region. Internal renewable water resources – composed of the annual flow of surface water and groundwater recharge – reach a total of 13.4 km3 annually, a third of world resources. That represents 27,673 m3 per capita, almost four times the world average (FAO, 2002). However, the irregular distribution of water resources in the region, in space and in time, adversely affects its availability. The result is that many territories and populations suffer from water stress because distribution does not keep pace with demand. Two parameters are used to measure water stress. One is the shortage of water to meet per capita needs, here considered to be a supply of less than 1,700 m3 annually per capita; when supply falls below 1,000 m3 the shortage is considered severe; when it is less than 500 m3 it is absolute (Falkenmark and Widstrand, 1993; Ohlsson, 1998). Local use has to be taken into account when assessing such values, since agriculture may demand more water – although of lower quality – than is required for domestic or industrial needs. Hence population figures are not an accurate measure of stress in watersheds with a low population density but with high agricultural use. The second parameter, used by the United Nations Organization (UNO), refers to extraction of more than 10 per cent of available water, estimated as the maximum natural replacement rate limit above which future availability is affected. Stress is classified as moderate if it is less than 20 per cent, medium-high between 20 and 40 per cent and severe when extraction is higher than 40 per cent of the replacement rate (Raskin and others 1997). The effect of extraction on availability depends, among other factors, on climate and run-off variations. In general, there is a very low level, only two per cent, of water extraction stress in Latin America and the Caribbean (UNEP and others, 2002). In the Caribbean, the average rises to moderate stress level (18.5 per cent) because of the rates in Cuba (13.7 per cent), the Dominican Republic (39.7 per cent), and Barbados (98.8 per cent); levels are low in other countries for which information exists (from 7.5 per cent in Haiti to 9.6 per cent in Jamaica). Levels in Mesoamerica fluctuate between 0.6 per cent in Belize and 5.1 per cent in Costa Rica, except for Mexico where pressure is greater (19per cent). In South America, with the exception of Argentina (10.4 per cent), levels fluctuate between 0.4 per cent in Bolivia and Colombia and 3.9 per cent in Ecuador. In some countries the quantity of usable water is fixed or decreasing, due to stress caused by moderate or greater withdrawal and growing demand. If future

The Amazon and Paraná-La Paraná-La Plata, among the world's world's largest water basins

Below is a more detailed sub-regional water resources analysis.

Area of the 10 largest water basins

South America South America, with 29 per cent of the world total, is the sub-region in Latin America and the Caribbean richest in water resources (UNEP and others, 2002). In decreasing order, average annual rainfall is: 1,991 mm in Andean countries, 1,758 in Brazil, 1,421 in Guyana and Suriname and 846 in the Southern Cone (FAO, 2002).

Amazon Congo Mississippi Nile Ob Parana Yenisey Lake Chad Lena Niger

Two of the world’s six largest watersheds are in South America: the Amazon and Paraná-La Plata rivers (WRI and others, 2001). The Amazon water basin is the world’s most extensive with 8.14 million km2 in seven countries (Brazil, Peru, Bolivia, Colombia, Ecuador, Guyana and Venezuela) and contains a fifth of its fluvial water (Revenga and others, 1998; GIWA, 2002). The Paraná-La Plata water basin is in sixth place, with 2.58 million km2 in four countries (Brazil, Argentina, Paraguay and Bolivia). Other important water basins in this sub-region are the Orinoco (Colombia and Venezuela) and San Francisco (Brazil) rivers. Ocean currents, the wind and mountain barriers, especially the Andes, determine the existence of extremely arid zones on the south Pacific coast, such as in the north of Chile where there are areas with no rainfall, and very humid territories such as the Baudó mountain range in Colombia where annual rainfall can be above 9,000 millimetres (mm) (Brown and Saldivia, 2000; SAMTAC, 2000). Arid and semiarid zones cover about 23 per cent of South America. In Argentina, the most arid country in the sub-region (60 per cent of the territory), 85 per cent of water resources are concentrated in the La Plata water basin, which occupies only 30 per cent of the territory (SAMTAC, 2000). In many areas with high precipitation there are also accentuated seasonal differences in some months, as well as a high level of variation from one year to another, intensified by intermittent global or local climate phenomena such as El Niño. Chile is illustrative in this respect; its extensive length presents great variations of rainfall, between the arid north where the scarce rainfall is concentrated between November and April, and the rainy south with abundant precipitation throughout the year, while the centre experiences the greatest variations between seasons and years (Brown and Saldivia, 2000). In 1998, average freshwater availability in South America was estimated at 35,437 m3 per capita annually, with wide national variations, from 7 453 m3 in Argentina to 316,891 in Guyana (UNEP and others, ·

2002). As indicated above, there are also great sub-national variations. In Chile, some northern regions received only 311 m3 per capita in 2000; this is in dramatic contrast to some southern regions with annual volumes of more than 3 million m3 (SAMTAC, 2000). In Brazil, water availability in the state of Roraima, in the Amazon region, is 1.5 million m3 per capita annually, while in the north-eastern state of Pernambuco it is only 1,270 m3 (Rebouças, 1999). In the Brazilian northeast there are other variability factors related to rainfall patterns and soil permeability, producing fluctuations from 0 to 600 mm between one six-month period and another. The Paraná-La Plata water basin, which covers 15 per cent of the South American territory and contains about 23 per cent of its population, is the only one below the shortage threshold, severe in this case, with a water availability of less than 1,000 m3 per capita per annum (Revenga and others, 1998). Applying the UNO parameter on national extraction averages to availability figures, it may be concluded that in general there is a low level of water stress in

South America. With the exception of Argentina (10.4 per cent), levels fluctuate between 0.4 per cent in Bolivia and Colombia and 3.9 per cent in Ecuador (UNEP and others, 2002).

them, the Bravo and the Usumacinta, share a border with the United States and Guatemala, respectively. The Bravo, which covers 608,000 km2, is the largest of these water basins; it rises in the state of Colorado (United States) and crosses several Mexican states until it flows into the Gulf of Mexico. The Rio Balsas water basin is below the severe stress threshold as to availability of water per capita (Revenga and others, 1998). Other important basins in Central America cover several countries and include the following rivers: San Juan (Nicaragua-Costa Rica); Coco (Nicaragua-Honduras); Lempa (El Salvador-Honduras-Guatemala); and Motagua (Guatemala-Honduras) (López, 2002). In Mesoamerica, levels of stress due to water extraction fluctuate between 0.6 per cent in Belize and 5.1 per cent in Costa Rica, with the exception of Mexico where pressure is greater (19.0 per cent) (UNEP and others, 2002).

Mesoamerica In Mesoamerica, the average rainfall is 772 mm in Mexico and 2,395 mm in Central America (FAO, 2002). In 2000 it was estimated that the average annual availability of internal renewable water resources was 4,137 m3 per capita in Mexico and 20,370 m3 in Central America, with a sub-regional average of 8,122 m3 (UNEP and others, 2002). There is a notable variation in national averages: from 2,831 m3 per capita annually in El Salvador to 70,695 in Belize. In addition, there are dramatic subregional differences. Mexico, for example, has tropical zones with very high precipitation, but also large desert areas (WWC, 1999). In Central America, two-thirds of the population on the Pacific coast of the isthmus receive only 30 per cent of total run-off (CATHALAC, 1999). Five of the main Mesoamerican water basins are found totally or partially in Mexico: the Yaqui, Bravo, Balsas, Lerma-Chapala and Usumacinta rivers. Two of

Averages can hide dramatic situations. For example, in Costa Rica the extraction index for groundwater supplying 60 per cent of the needs of the San José large metropolitan area (with half the national population), rose from 16 to 62.5 per cent between 1996 and 2000. This represents an extreme water stress level – for example, similar to or greater than in Egypt, Libya, the Arab Peninsula and the Near East (Fernández-González and Gutiérrez-Espeleta, 2002). In Mexico, groundwater represents a third of the country’s total extraction and two-thirds of the urban drinking water supply (WWC, 1999). In the Valley of Mexico metropolitan zone, including the federal capital, extraction levels now double the aquifer’s recharge capacity and are an important contributor to what the government has called “a matter of national security” (GDF-BID, 1999; GDF, 2000; Weiner, 2001; see the section on Urban Areas).

The Insular Caribbean Precipitation in the Caribbean fluctuates between 1,141 mm annually in the Lesser Antilles and 1,451 in the Greater Antilles, with an average annual availability of 2,668 m3 per capita (FAO 2002; UNEP and others, 2002). Antigua and Barbuda, Barbados, Haiti and Saint Kitts and Nevis suffer from the region’s most severe water shortage. These countries and other territories in the Lesser Antilles have almost no freshwater ecosystems and depend extensively on their groundwater to meet the demand of human activities (UNEP, 1999). Water stress is classified as absolute in Barbados and as severe in the other cases, except Haiti (UNEP and others, 2002). Even a slight reduction in rainfall and a rise in sea level would have serious consequences for the islands whose freshwater sources are limited and whose coastal aquifers are susceptible to saline intrusion. Antigua and Barbuda, the Bahamas and Barbados are already using desalinated sea water (Cordeiro-Netto, 2001).

Latin America and the Caribbean

Pressure on water resources The main pressure on water availability comes from excessive extraction and the impermeability of receiving zones due to urban infrastructure and deforestation (WRI and others, 2001). Forests and other vegetation help to maintain the quantity of water and preserve its quality, reducing runoff in periods of high precipitation and maintaining flows in dry periods (see the section on Forests). Soil impermeability caused by construction prevents rainwater from seeping into aquifers and accelerates run-off in periods of high precipitation (see the section on Urban Areas). To satisfy demand for water for agriculture, industry and direct consumption, excessive extraction of water resources may exceed their natural replacement capacity, exhausting water sources and leading to salinisation of groundwater close to coasts (CESACM and others, 1995). In the case of moderate or greater withdrawal levels, it is cause for concern that, while the amount of usable water is fixed or decreasing, demand is increasing, above all because it is the region with the largest agricultural land reserves and, thus, with most demand for irrigation water.

Water demand and use in the region Water has not been a limiting factor to social development, except in a few countries. Over the past 30 years, however, there has been a considerable change. Because of population growth, urbanisation and economic progress, the demand for water is growing

throughout the region (WWC, 2000). In specific areas, especially the Caribbean, drinking water availability has quickly become one of the principal factors that limit socio-economic development. Many governments find it hard to supply water to the whole population, while at the same time maintaining or improving quality standards. In the past three decades withdrawal and consumption of water have doubled in Latin America and the Caribbean, at a rate much higher than the world average. It is expected that this trend will continue, with an increase of 21 per cent in total withdrawals in Mesoamerica, and 43 per cent in South America by 2025 (ECLAC and UNEP, 2001). In general, there is good access throughout the region to drinking water and sanitation services. In 2000, for example, 85 per cent of the regional population had access to drinking water and 79 per cent had some kind of basic sanitation (drainage, septic tanks or latrines), significant increases over 1971 when only 53 per cent had access to water (PAHO, 2001). However, these access figures must be qualified by taking into account the great inequality among users, even in countries with most water resources. Many rural and urban poor have no access to clean water or to sanitation services (WWC, 2000). In countries such as Brazil, for example, the poorest 10 per cent of the population pay up to three times more for water than the richest 10 per cent (relative to their incomes), with most inequality in rural areas (OPSOMS, 2001). Up to now, drinking water standards have centred on its bacteriological quality, usually obtained by chlorination which has an impact on health because of its

residual effects (Craun, 2993). Physical-chemical controls on water for human consumption – although included in regional norms – are much more recent and much weaker.

Demand for water for direct domestic consumption is also increasing, resulting in significant pressure on aquiferous layers that bear a significant part of that demand. In many Caribbean countries, as well as in Colombia and Panama, the highest volume is destined for domestic use. At present, 150 million urban dwellers in the region (31.3 per cent of the total population) depend on groundwater for their direct needs (CELADE, 1998; Revenga and others, 2000). In Barbados, where 79 per cent of water resources come from groundwater, 98.6 per cent of the drinking water supply depends on this source (Ministry of Physical Development and Environment, 2001).

The principal demand for and the main use of water is in agriculture, followed by domestic and industrial consumption. In the three sub-regions, more than 70 per cent of use is agricultural (UNEP and others, 2002). Only Brazil, Colombia, Cuba, Venezuela and the countries in the Lesser Antilles are below the regional average. Domestic use of water fluctuates between 18 and 25 per cent in the sub-regions, while industrial use varies between one and 11 per cent, also with naAnnual freshwater use per sector tional differences.

The pattern of groundwater use seems to be similar, with most withdrawal destined for agriculture. Although data are only available for Argentina, Brazil, Mexico and Peru, these indicate that only in Brazil does domestic use of groundwater equal agricultural use (38 per cent compared to 25 per cent for industrial use UNEP and others, 2002). In the other countries, agricultural use is always higher, fluctuating between 60 and 70 per cent, while domestic use is 11 to 25 per cent, In Argentina industrial use is higher than domestic use (19 per cent compared to 11 per cent).

Effects on water quality Water pollution problems in Latin America and the Caribbean became evident during the 1970s. Most pollution is caused by agriculture and the discharge of untreated urban and industrial sewage. Before that the Seventies, low levels of intensive agriculture, urbanisation and industrialisation confined such problems to the largest cities. Over the past 30 years there has been a significant lowering of the quality of surface water and groundwater.

Latin America and the Caribbean

Agriculture contributes to the deterioration of surface water and groundwater by excessive run-off, soil erosion, pollution (from fertilisers, herbicides, pesticides and organic waste) and disproportionate irrigation. Excessive use of fertilisers in agriculture has increased eutrophication of lakes, dams and coastal lagoons. Rising levels of nutritive substances increase the growth of algae which compete with other living beings for oxygen, reducing biodiversity in bodies of water. In Nicaragua, pesticides have contributed to degrading water quality, particularly in Leon, the Sebaco valley, the Matagalpa and Jinotega horticultural areas, and the tobacco production zones in Esteli (MARENA, 2001). In Costa Rica, metropolitan and rural nitrate levels have been found to be close to or above international standards (Fernández-González and Gutiérrez-Espeleta, 2002). At the beginning of the 1990s, that Mesoamerican country’s coffee wastes represented 68 per cent of the volume of pollutants in Central Valley rivers; norms introduced since then to reduce the discharge of coffee wastes have succeeded in bringing this figure down to 45 per cent (Boyce and others, 1994). In South America the situation is similar. In Colombia, for example, coffee wastes accounted for a biochemical oxygen demand of 3.7 million tonnes annually (PNUMA- PAM, 2001). In Peru the high doses of agrochemicals and fertilisers in coca crops, and compounds used to prepare basic coca paste affect rivers in the highland forests (CONAM, PNUMA, 2001). Although concentrations of nitrates in South American riv-

ers seem low compared to European rivers (the world’s most polluted), they are greater in the more populated Magdalena and Uruguay water basins where agriculture is more intensive. In Chile, a study of water in the Rapel river basin and sediments found a close relationship between toxic effects and mutations and the use of pesticides in agriculture and mining activity in the zone (Castillo and others, undated). Furthermore, it has been shown that eutrophication of bodies of water is rapidly increasing all over the country (CAPP, 2000). Another effect of intensive agriculture is the extension of irrigated areas, with a subsequent increase in the concentration of salts on the soil surface and seepage of agrochemicals into surface and groundwater. Some irrigated zones in the north of Chile, for example, now suffer from severe salinisation (CAPP, 2000; ECLAC and UNEP, 2001). When irrigation water is contaminated by industrial or residential effluents, agricultural products become a threat to the health of farmers and consumers. In general, waste waters in Latin America and the Caribbean are untreated and discharged raw into bodies of water. About 21 per cent of the population has no access to any type of sanitation, 31 per cent only has septic tanks or latrines, and 49 per cent has access to drainage, although most effluents are untreated. However, there are significant national and sub-national differences. All the effluents in Antigua and Barbuda and

Barbados are treated to some extent, while there is no treatment at all in countries like Grenada, Dominica and Haiti (PAHO, 2001). Although there are sewage installations, most do not have enough capacity for effective treatment. The increase in pollution from urban run-off, as well as the discharge of untreated sewage into bodies of water that serve urban areas, add to the difficulties of satisfying a growing demand for water in cities (WWC, 2000). A study carried out between 1996 and 1998 in the metropolitan region of Rio de Janeiro showed a failure to comply with Brazilian norms on the concentration of: ·

faecal coliform (more than 50 per cent of the samples);

·

nitrates (31 per cent of the samples in the zones studied); and

Similar results have been obtained since the 1970s on excessive concentration of nitrates in other metropolitan areas such as Greater Buenos Aires (Foster and others, 1987). Industrial growth and resulting toxic, bacteriological and organic (from food production industries for example), pollution has had a serious effect on water quality. Animal wastes from industrial livestock activities contaminate aquifer deposits with coliform bacteria. In general, the evolution of the biochemical oxygen demand from emissions between 1980 and 1997 clearly indicates a rise in pollution caused throughout the region by industrial activities, although countries differ as to the degree of pollutants in industrial sectors (mining and petrochemical, among others - WWC, 2000).

Rio de Janeiro (1996-1998)

Mexico’s industrial sector, for example, consumes 4.1 km3 of water annually, 7.6 per cent of the country’s total use. Of the water extracted, 89 per cent is converted into sewage, adding an annual biochemical oxygen demand of 6.2 million tonnes. This amount could be used in the same period by 95 million people, equal to Mexico’s total population in 2000 (SEMARNAP, 2000). Most industrial effluents are untreated before they are discharged into water, coastal or marine ecosystems. In the Dominican Republic, for example, only 31 per cent of industrial wastes are given primary treatment (PNUMA, PUCMM, 2000). By draining generally toxic liquid and solid wastes, mining causes a serious impact on the environment and on health. An example is the quality of water in the Sources: Freitas and others, 2001; Foster and others, 1987.

and the erosion, of soils naturally rich in mercury by deforestation and agriculture have caused high concentrations of this element to enter aquatic environments (UNEP, 2002). Another growing problem is the salinisation of coastal aquifers due to excess extraction for industrial use. In the Caribbean this is particularly severe as a result of the rising demand for water, above all to supply the tourism industry (UNEP, 1999). Such pressure affects not only the direct human use of water resources (consumption, transport, recreation) but also other environmental services of freshwater ecosystems, including their capacity to serve as habitats for huge numbers of flora and fauna species, as well as flood mitigation (Revenga and others, 2000). Other sources of human pressure, such as building dams and diverting or changing river courses, are associated with those already mentioned in reducing the ecological flow needed to maintain these functions.

Water policies: national and regional initiatives During the second half of the 20th century, countries in Latin America and the Caribbean promoted sectoral strategies, including projects to confront development challenges in relation to water resources. Various specific guidelines were prepared on drinking water supply, sanitation, irrigation and hydropower. There were divergent legal and administrative responsibilities and the initiative was generally in the hands of centralised state agencies, with little or no participation by other interested stakeholders. Regulations and controls adopted a punitive approach, with few incentives or economic instruments. Furthermore, the capacity to ensure compliance with legislation –generally disperse and often conflictive – did not have the necessary force. The limits of these policies became evident. When the demand for water was concentrated in particular regions and on particular uses, it gave rise to growing conflicts about water use and the impact caused by the resource’s degradation and depletion. These conflicts have highlighted the strategic importance of questions such as:

·

·

The need for adequate mechanisms to allocate water to different users (taking into account not only effective availability, but also types of demand, as well as the true value of the water for each use, with the environmental services needed to produce it);

·

Closely linked to the above, the question of whether to privatise or decentralise elements of water production and distribution (including the creation of local or regional markets for the different uses of water, and

the definition and allocation of property rights needed to establish such markets); ·

Administering water resources through an integrated approach that goes beyond a fragmented sectoral vision and promotes national and international watershed management initiatives, and

·

Defining and urgently implementing adequate urban and industrial sewage treatment.

To respond to these challenges, in recent years most countries in Latin America and the Caribbean have begun to introduce political, legal and institutional reforms (Jouravlev, 2001). Brazil, Chile, Colombia, Jamaica and Mexico have already reformed their water administration frameworks, and in the remaining countries substantial changes are being proposed in the midst of a strong public debate. There is a trend towards creating institutions that represent the public sector and the main users’ groups. Their objectives include: ·

formulating water policies;

·

coordinating multiple use of water through concessions and standards;

·

directing the development of large hydraulic works;

·

supervising pollution control, protecting against flooding, and

·

and estimating the ecological water flow (Jouravlev, 2001; FAO, 2002).

Examples of this trend may be seen in Bolivia, Chile, Costa Rica, Guatemala, Honduras, Mexico and the Dominican Republic. National water resources authorities are also being established in Antigua and Barbuda, Belize, El Salvador, Panama and Saint Lucia, to coordinate basin authorities or users’ associations. Regulatory frameworks are being reviewed to include these new institutional processes in countries like Bolivia, Chile, Costa Rica, El Salvador, Honduras, Panama and the Dominican Republic. Another important trend in the past decade has been the partial or total transfer of water services from the public sector to decentralised bodies, public (local governments) and private (including community associations), especially for drinking water but also for sewage collection and urban sanitation (Jouravlev, 2001; PAHO, 2001). Mexico, Colombia, Cuba and Ecuador have begun decentralisation processes although, as they were undertaken in haste and without adequate technical support and regulations, results have not always been positive. An active community presence has been recognised as effective and important when making deci-

sions on how to supply the services. This has happened especially in rural areas and zones on the outskirts of urban areas, and most countries in Central America and the Caribbean, for example, have had some success in this respect. Argentina, Brazil, Chile and Colombia have promoted the sale or concession to private operators of supply and sanitation services (Jouravlev, 2001; PAHO, 2001). Efforts have also been made to promote new tariff rates so that water is paid for at its true value (including costs of replenishing, maintaining and expanding services). In 1998 a provincial state public company in Costa Rica became a public corporation in which municipalities were the shareholders. Since 2000, this company has been charging a water tariff that incorporates the cost of protecting the forests and water basins needed to guarantee users a sustainable water supply (Jouravlev, 2001; MINAE, PNUMA, 2002; ESPH, 2002; Barrantes and Castro, 1999). However, the efficiency of privatisation and the use of economic instruments such as the price of services continue to be highly controversial (WWC, 2000). Some States have not yet adjusted to their new role as supervisors or regulators of privately-held public services in order to deal with distribution or social equity prob-

lems regarding access to the resource (WWC, 2000). The need to transfer water-saving technology and improve control strategies, both with respect to tariffs and fines, has also become evident. Throughout the region the idea that a hydrographic basin is the most appropriate geographic entity for planning and managing the multiple use of water resources has gained ground (CEPAL, 1999). Over the past 50 years considerable experience has been gained in administering water basins at the sub-national and sub-regional levels (CEPAL, 1994). These include the Papaloapan Commission and other commissions in Mexico, promoted in the period 1947-1960 as a regional but centralised development instrument (building roads, schools, urban improvement, and health). Other similar examples are the San Francisco Valley Commission in Brazil (1948) and the Cauca Valley Corporation in Colombia (1954) (CEPAL, 1994). There have been more recent national and sub-regional water basin management initiatives. One of the most developed sub-regional experiences is the La Plata Water Basin System established in 1967 by Argentina, Brazil, Bolivia, Paraguay and Uruguay, which was endorsed by an international agreement in 1969 (CIC, 2003). For 25 years the System has been administering

Regional integrated water resources management efforts The idea of integrated and participatory resources management began to gain ground worldwide following the first international conference on water in Dublin and the Earth Summit in Rio de Janeiro, both held in 1992, and was reinforced following the Dublin + 10 and Rio + 10 conferences and the three world water fora, all held during the period 1997-2003. This new vision has gradually been adopted by a growing number of international, regional and national organisations. As part of this trend, in 1993 the Inter-American Water Resources Network (IWRN) was established as a network of networks of more than 130 institutions, with a technical secretariat at the headquarters of the Organization of American States (OAS) and 34 national focal points. The IWRN held Inter-American Dialogues in 1993 (Miami), 1996 (Buenos Aires), 1999 (Panama City) and 2001 (Foz do Iguazù, Brazil). Its main objective is to create and strengthen water resources associations, as well as collaboration between governments, academic institutions, NGOs, private sector water users' associations and individual professionals, to exchange information and technical experiences on integrated management of the continent's water resources. At present IWRN's main agenda items are: · · · ·

transboundary water basin management, metropolitan zones water management, the effects of climate on water resources and the management of water resources in arid and semiarid zones.

Other important continental initiatives are being developed within the framework of this new vision. Those with global coverage include consultations and studies promoted by the Global Water Partnership (GWP) and the Global International Waters Assessment, (GIWA). Regional or sub-regional projects include the Everglades-Pantanal, the Guaraní Aquifer, the La Plata water basin initiative, and the Central American Water Resources Action Plan.

a fund which now amounts to US$350 million, promoting projects on road, rail and river transport, other infrastructure works such as bridges, dams and pipelines and regional development poles (CIC, 2003; FONPLATA, 2003). On a national scale, there have been some recent experiences in Cuba, Brazil and Argentina. Cuba established a National Hydrographical Basin Council in 1997, defining a water basin as the basic environmental management unit. This has allowed notable advances to be made in reforestation, soil conservation and pollution control, particularly in the Cauto river water basin, the country’s most important. In Brazil, the 1997 National Hydraulic Resources Policy (Law 9433) established a National Hydraulic Resources Administration System that seeks to unify measures concerning water use (Brañes, 2001). Argentina has found, with inter-provincial water commissions, that tensions can arise between centralism and federalism when making collective decisions on distributing flows between provinces, supplying the population, using irrigation, generating hydropower and industrial, mining and petroleum uses of water (CEPAL, 1999). However, in spite of the significant advances made in the region in the approach to the use of water basins, in general terms it may be said that present experience in Latin America and the Caribbean is limited to sectoral water management for specific uses (hydroelectricity, irrigation, supply of drinking water and sanitation).

management. Management policies tend to depend on centralised authority, control measures and institutions instead of on economic instruments and incentives or new territorially-decentralised institutional arrangements. Investment is needed to improve the capacity of institutions responsible for managing water. Without it, the use of economic instruments, although raising income to some extent, will not reduce impact on the environment or improve efficiency (Motta and others 1997). Although Latin America and the Caribbean as a whole continues to be a region rich in water resources, the increase in the demand for and the pollution of such resources is exerting growing pressure. While estimates suggest optimistic outlooks for most countries in the region, the figures do not distinguish in what measure the water is technically and economically useable (Cosgrove and Rijsberman, 2000); in effect, because of limitations as to economic capacity or infrastructure, not all water in these countries is fit for human consumption. In addition, the water availability indicator does not provide information on the distinction between water use and policy options to mitigate shortages. It does not reflect seasonal volume variations, or consider the quality of available water and its suitability for use. If things go on as they are, water availability will become one of the most critical matters facing the region in the coming decade.

Water basin management as multi-sectoral water management or even as a geographically-integrated approach to ecosystem management, still hardly exists and is given little consideration in the region. In most countries, water resources management takes no account of water’s vital interaction with much larger ecosystems, or with other ecological functions and water services. Little information is available on water resources’ environmental and socio-economic conditions and impact on efforts to establish basin-scale

The Guaraní Aquifer 2

The Guaraní Aquifer System is one of the world's largest, covering about 1.2 million km in southeast of South America, with a population of 15 million in Argentina, Brazil, Paraguay and Uruguay. The system's water reserves are estimated at approximately 40,000 km3, with an annual recharge of 160 km3. These reserves can meet the water demands of 360 million inhabitants (estimated at 300 litres per day per capita) for 100 years, using only 10 per cent of its total capacity. In 2002, the four governments, with support from donors and international organisations, began to prepare a joint management framework for the water system, adhering to principles of environmental sustainability and public participation. The project includes taking advantage of the enormous geothermic potential of the water system which in some regions produces up to 100,000 litres per second at temperatures between 33 and 50 degrees Celsius.

The Cuban experience in water basin management - an ongoing success story The National Water Basins Council (CNCH) was established in 1997 as a result of Agreement 31/39 of the Cuban Council of Ministers' Executive Committee. The CNCH made it possible to modify concepts of integrated water basin management by defining water basins as “the basic units of environmental management”, bringing together all existing natural resources and the economic and services structure, to achieve an environmentally-balanced social development. The first stage defined the country's eight priority water basins according to their economic, social and environmental complexity and the effect on their natural resources and general features. These are: Cuyaguateje, Almendares-Vento, Ariguanabo, Zaza, Hanabanilla, Cauto, Toa and Guantánamo-Guaso. They cover 15,000 km2 in 11 provinces, with more than 40 per cent of the Cuban population, and they account for about 60 per cent of the country's economic activity. In the period 1999-2001 the (annual) National Economy Plan allocated close to 57.000 million pesos for national water basin management. To complete the organisational structure, 15 provincial councils were created, one in each province (including the Special Municipality of the Isla de la Juventud), as well as five councils for specific water basins (Cauto, Almendares-Vento, Ariguanabo, Zaza and Hanabanilla. Their main function was to coordinate activities for water basins shared by provinces. In turn, the provincial councils selected 49 as of interest to the provinces, planning and periodically evaluating the work being done, and deciding how to allocate investments according to the problems identified. Applying their own methods, they prepared diagnoses and action plans to be applied with the coordination and participation of all the State Administration Agencies (OACE). The diagnoses showed that today's most serious environmental problems in water basins are deforestation, soil degradation and water pollution. More than 30,000 hectares are affected by deforestation, 498,291 by heavy erosion, 831,435 by deficient drainage and 977,040 by heavy salinity. Of the pollution sources identified in the national inventory, 26 per cent (542) account for an annual biochemical oxygen demand of 89,836 tonnes (246 tonnes a day), equal to a population of 5,860,143. Of all the water basins, the Cauto has been most affected by centuries of human activity. For this reason the best examples of integrated water basin management in the country are activities in the Cauto basin in the period 19972001.

In the period 1997-2000, an area of 19,474.6 ha was reforested and in 2001 reforestation was completed on 4,600 hectares of the main river's (Cauto) hydro-regulating channel. A total of 159 forest farms have been established which cover an approximate area of 7,780 ha and employ 1,300 farm workers. There are more soil conservation and improvement measures in place and in 2001 close to 35,000 tonnes of organic material were applied. Expressed as the biochemical demand for oxygen, pollution has been reduced by the treatment and economic exploitation of sewage water, in percentages of 6.3, 16.3 and 8.7 in the three years from 1999-2001, indicating a solution may be found for the most serious water pollution problems.

This water basin is the most extensive and important in 2 Cuba, with 8,969.2 km , or eight per cent of the national territory and 10 per cent of the population. Its area includes part of the eastern provinces of Las Tunas, Granma, Holguín and Santiago de Cuba. The basin is of special importance because of its valuable natural wealth, a significant and varied agricultural and industrial activity, strong hydraulic development, important mining and fishing resources as well as important cultural and historic values.

Environment Outlook

Coastal and marine areas

T

he main environmental problems endangering coastal and marine areas in Latin America and the Caribbean are pollution and degradation. Pollution comes from human settlements (especially if there is a concentration of industrial and electric power generation installations in port zones), agriculture, tourism, maritime transport (above all because of spills of hazardous substances or the introduction of exotic species), and the extraction, processing or transport of petroleum and gas. Degradation, which affects ecosystems and species, is a consequence of the excessive use of these resources and the conversion of natural habitats by either human activities or the impact of natural events. It is predicted that limited change will bring about a significant worsening of coastal and marine degradation (UNEP, 2000). For both historical and geographical reasons, Caribbean habitats are particularly vulnerable to this phenomenon, because their small island territories and extensive coasts have fewer defences against any rise in sea level or frequently occurring extreme hydro-meteorological event. The underlying causes of these problems are linked to growing demographic pressure on coasts and the subsequent expansion in coastal land use. This settlement entails agriculture, the construction of settlements, ports, roads and tourism infrastructure and, in many areas, the establishment of mariculture installations. Not only have these pressures reduced the natural productivity of coastal areas; it is also estimated that most coastal fish species have been seriously over-harvested. The Latin America and Caribbean region has drawn up policies that are reasonably comprehensive in response to the main environmental pressures on coastal and marine areas, particularly with respect to global, regional and sub-regional issues (Hoggarth and others, 2001). More specific action needs to be taken at both national and local levels to mitigate the impact of landbased activities on coastal areas, particularly when integrating basin and coastal management into mitigation policies and, above all, preventive policies. There is also a need for sub-regional integration of global and regional policies that define the different management options. A critical problem arising here is the availability of resources in national institutions – especially in small countries or dependent territories – in order to deal effectively with the most serious pressures and their impact on these countries. A major obstacle is the difficulty to articulate in multilateral environmental agreements (MEAs) what are the different commitments and priorities related to the coastal-marine problem, espe-

93

cially when small countries are unable to make effective use of the international support offered by MEAs to implement their agreements.

General ecological situation in the region’s coastal and marine areas Coastal and marine areas provide the population with environmental services (benefits) and strategic natural resources. These services include regulation of the climate, protection of coasts and balancing the chemical composition of the atmosphere. Raw materials extracted from the sea include petroleum, gas, salt and various construction materials, to which must be added the direct extraction of energy that started in the region several years ago. These areas also provide a habitat for flora and fauna that have been intensely harvested for thousands of years for food and for traditional artisanal use. They also maintain genetic diversity and offer opportunities for tourism. The coastal and marine areas of Latin America and the Caribbean support a complex interaction of ecosystems, with an enormous range of biodiversity, and figuring amongst the most productive ecosystems in the world. They are subject to natural factors and socioeconomic (or management) factors, the latter incorporating anthropogenic (or human) “pressures”. Natural conditions may be classified on different scales. These range from biogeographic “provinces”, or large marine ecosystems, that extend over tens of thousands of square kilometres, to “regions” (with hundreds of thousands of square kilometres), and local coastal ecosystems that extend over areas of dozens or hundreds of square kilometres (Hoggarth and others, 2001). Large regional marine ecosystems are defined by the geomorphology and local geography of seabed and coast, as well as by climate, solar radiation, water salinity, the deposit of sediments from land sources and the dynamics of hydrological events brought about by winds and the main ocean currents. A major climate event in the region is El Niño, which cyclically alters the temperature of marine currents and patterns of precipitation, affecting fishing and leading to drought and severe flooding. Although El Niño is independent of any global warming allegedly caused by human activities, it is thought that its recent more frequent occurrence, persistence and intensity may be influenced by global warming (IPCC, 2001; see box on page 124). The great regional marine ecosystems may be classified in two large groups: open seas and semi-enclosed seas (UNEP-GPA, 2001). Some of the former are limited by ocean currents (in the North or South Pacific, and in the Atlantic south of Brazil) or by the continental

platform (Mexican and Central American South Pacific, the Atlantic south of Argentina and north of Brazil). The semi-enclosed seas are classified according to their high or low ecological charge capacity and cleanliness; among the first are the Caribbean and the Gulf of Mexico, while the Gulf of California is an example of the second. Local ecosystems are also subdivided into two groups: those defined by geomorphologic aspects and those defined by vegetation. Among the first are the deltas that form drainage rivers, cliffs, coastal lagoons, dunes, sandy or stony beaches, estuaries (riverside plains periodically flooded by tides) marshes (swamps with vegetation and brackish water) and rocky and coral reefs. Further away from the coast can be found the neritic zone (water on the continental platform), the pelagic zone (open sea) and the deep bottom or abyssal plain where benthic (totally submarine) ecosystems are found together with submarine ditches and hydrothermal vents (hot water outflows surrounded by living organisms). The principal ecosystems defined by their vegetation are mangroves, marine grasslands and large algae or “macroalgae” communities. Latin America and the Caribbean has 64,000 km of coastlines covering 16 million square kilometres (km2)

·

of marine territory (UNEP-GPA, 2001). The American Pacific coasts characteristically have a very steep narrow platform (usually less than 20 kilometres wide) descending abruptly to extreme marine depths (6,669 metres in the Mesoamerican ditch and 8,065 metres in the Atacama ditch, both off the coasts of Chile and Peru), with strong ocean influences (namely, the California current north of the Equator, and the Humboldt current south of the Equator). In the Caribbean and the Atlantic, on the other hand, the continental current is usually shallower and more extensive, fluctuating between 2,400 and 4,500 metres. The most important exceptions to this general rule are the broad continental platform of the Gulf of Panama in the Pacific, contrasted with the depths of over 8 380 metres in the Puerto Rico ditch (Bakun and others, 1999; EDC-RIU, 2003a, 2003b, 2003c; Richards and Bohnsack, 1990; Wells and Enfield, 1999). Among the marine areas with the greatest biological productivity are open sea surges, where deep currents drag up nutrients from the sea bottom, and also the mouths of large rivers that bring nutrients from the land to the sea (UNEP-GPA, 2001). Seventy per cent of commercially important species are to be found in these areas. As a result of the surges caused by the California current in the north and the Humboldt current in the

Environment Outlook

south, productivity in the Pacific is greater than in the Atlantic or the Caribbean, especially from fishing organisms that are pelagic (open sea) and small demersal species (found on or near the ocean floor) (Hoggarth and others, 2001). Large-scale variations in currents and nutrient flows, such as those caused by El Niño, have significant effects on the fishing of coastal and deep water species. Mangroves and coral reefs form two large and very productive coastal ecosystems (in relation to their biological diversity) and are generally located in the regional tropics. Mangroves cover between 40,000 and 60,000 km2, mostly along the Equatorial coasts (UNEPGPA, 2001). Brazil, together with Indonesia and Australia, is one of the three countries in the world with the largest areas of mangroves; Chile, Argentina and Paraguay are the only countries in the region without any mangroves. As for reefs, 12 per cent of the world’s coral reefs are located in the Greater Caribbean, which has the second largest barrier reef, extending for 700 kilometres along the coasts of Mexico, Belize, Guatemala and Honduras. These reefs serve as habitats for many critically endangered species (UNEP-GPA, 2001). Tropical marine systems are generally more vulnerable than temperate climate systems to the impacts of human activity and climate change. Other determining factors are the extension of the continental platform,

the depth of adjacent seas, surges and the speed of marine currents crossing them. For example, the Central American Pacific coast is often less vulnerable to polluting discharges than the Caribbean because the sea is deeper (which increases its diluting capacity) and there are more currents to carry pollutants.

Principal anthropogenic pressures and their impact The state of coastal and marine areas also depends on patterns of socio-economic use and management. The degradation caused by the over-harvesting of resources and the conversion of natural habitats occurs in densely populated areas or zones with a high concentration of road, port or oil infrastructure, and subject to pressure from fishery, shipping and tourism activities. In such places water use is intensive but management is poor with little or no regulation or serious effort made for conservation. Taking into consideration population density, road infrastructure and the existence of gas or oil pipelines, one general assessment of the world’s coastal areas has suggested that 29 per cent of the coasts in Mesoamerica and 50 per cent in South America are either endangered or critically endangered (WRI and others, 1996).

Impact of global warming and El Niño on coastal and marine areas in Latin America and the Caribbean According to the Intergovernmental Panel on Climate Change (IPCC), warming of the land atmosphere —aggravated by burning fossil material, among other human activities— could have dramatic effects on coastal and marine zones in Latin America and the Caribbean during the 21st century. The IPCC considers it “highly probable” that a projected increase of 5 millimetres annually in sea level (as a result of the melting of the North Pole ice caps) will cause extreme meteorological events such as floods and hurricanes with “fairly probable” negative effects on coastal ecosystems and settlements, including impacts on productive activities and infrastructure. It is “highly probable” that biodiversity losses will increase. In small island states, like those in the Caribbean, it is “highly probable” that coastal erosion will increase, with property losses and displacement of populations. Coastal ecosystems (coral reefs, “marine grasslands” and mangroves) will lose resilience, and fauna and associated economic activities will be affected. In addition, there will be an increased risk of heavy swells caused by storms and of salinisation in freshwater underground deposits. Climate change is increasing the effects of El Niño, a phenomenon produced by changes in the trade winds affecting ocean water depths and raising its surface temperature (see the section on Atmosphere). One of the first effects of El Niño on the human population to attract attention was its impact on fisheries. The principal effect is on the surges which are normally very rich in nutrients but become impoverished because incoming masses of warm water disrupt the trophic chain. Furthermore, the warmer water brings with it tropical and semitropical organisms capable of swimming great distances to sites outside their natural distribution. This has an ecological effect which, although not yet well understood, is known to reduce the fishing catch in the usual fishing grounds while increasing it in others.

We also need to consider what policy responses have been made to these pressures. Significant efforts have been made for some of the region’s coasts that are subjected to intensive use (such as Cancun in Mexico, a large part of the Lesser Antilles and parts of the Brazilian tropical northwest Atlantic). In general it can be said that little environmental management exists for most of the large regional marine ecosystems (Sullivan and Bustamante, 1999).

Endangered coastal ecosystems

Population Sixty of the 77 largest cities in Latin America and the Caribbean are situated on the coasts, and sixty per cent of the population live less than 100 kilometres from the sea (Cohen and others, 1997). Rural-urban migratory patterns, together with the growth of medium and small cities, are causing coastal population density to rise, exerting growing pressure on coastal waters and plains (UNEP, 2000). This demographic factor has been estimated to endanger some 39 per cent of South American coasts – a percentage considerably higher than the world average (Hoggarth and others, 2001). Rivers are bringing pollutants from inland watersheds and population centres down to estuaries and coastal zones, so the number of people whose inland activities affect coastal and marine zones is higher than the number of the coastal population. Generally speaking, while the population continues to grow, its impact on coastal ecosystems will also increase, principally be·

cause most urban and industrial sewage is reaching the coasts without proper treatment, and there is growing use of agricultural chemicals that later reach the sea through run-off.

Tourism Tourism is one of the main economic activities in countries throughout the region, especially in the Caribbean. The total annual income from tourism rose from US$14,300 million to US$45,400 million in the period 1990-2001, and its share of world tourism income grew from 5.5 to 6.8 per cent (WTO, 2002a; 2002b). During the same period, the number of tourists visiting the region annually rose from 21.1 to 35.8 million. The Caribbean sub-region accounted for 54 per cent of this income and 47 per cent of visitors. In coastal areas, the development of tourism encourages greater competition for sites to build hotels, ports, roads and for other intensive-use activities. Such expansion of the tourism infrastructure (like urban expansion in general) is leading to erosion and changes in habitats which are interrupting the basic ecological processes. Liquid wastes, litter and hazardous wastes are discharged into the open sea from cruisers and then pollute marine and coastal ecosystems, affecting both flora and fauna.

Land-based marine pollution Land-based marine and coastal pollution comes from agricultural and industrial activities and human settlements, getting worse in areas where tourism has expanded. Sewage, sediments, nutrients, floating solid wastes, petroleum hydrocarbons, toxic wastes and pesticides all end up on the coast (PNUMA, 1994). Land pollutants reach the coast by run-off and erosion conveyed by rivers and also, in some cases, by the wind. Ninety per cent of pollution from sewage discharged into the coastal zone is carried by rivers and streams (UNEP-GPA, 2001). A dramatic example of the capacity of rivers to carry pollutants to the sea is shown in the transboundary effects of five main watersheds: the Amazon, the Mississippi, the Orinoco, the Plata and the Santa Marta. Satellite images have revealed substantial discharges of sediments emerging from coastal rivers and some large islands and travelling over hundreds of kilometres of ocean. During one episode of fish mortality in the Windward Islands in February 2000, pathogenic bacteria were detected which had earlier only been reported in freshwater continental systems. It was suggested that the pollutants had been introduced in sediments as a result of flooding in the Orinoco basin (Hoggarth and others, 2001). Only around 14 per cent of sewage from public drainage (covering only 6.6 per cent of the regional

Pesticide run-off into the Caribbean Sea Information available on the type, concentration and effects of pesticides in marine and costal ecosystems in the Caribbean is specific and isolated. However, a recent study coordinated by the Caribbean Environmental Programme of UNEP in Nicaragua, Costa Rica, Panama and Colombia presents an initial survey of the situation. In all these countries, appreciable concentrations of organic phosphorous and organic chlorate compounds (such as aldrin, dieldrin, lindane and DDT) have been measured in samples of water, sediments and live organisms taken from the Caribbean Sea and coasts. Between 1983 and 1987, the Cauca River in Colombia was found to contain organic chlorinated compounds in concentrations above the limits established by the United States Environmental Protection Agency. The extensive use of pesticides in the Cauca zone has its effects in the Caribbean Sea. The presence and highly toxic potential of organic chlorinated compounds have also been demonstrated in fish, crustaceans and other species. In Costa Rica, for example, pesticides have been found close to the Tortuguero Conservation Area and the Cahuita National Park in concentrations that represent an acute and chronic degree of toxicity for aquatic organisms. In Panama, pesticide run-off reaches the San-San River, designated as a refuge for endangered manatees. All four countries concerned have water-quality monitoring and control programmes. However, existing knowledge must be integrated and systemised to reveal the connection between sources of pollution and the current state of natural resources and public health. The lack of resources presents a key challenge for following up recommended actions and when responsible institutions wish to disseminate information. Source: PNUMA, 1999.

population) is treated in Latin America and the Caribbean; another 30 per cent of the population is treated by in situ sanitation (septic tanks, and other similar systems) (PAHO, 2001), leaving just over 60 per cent without any sewage treatment means. A large proportion of their untreated sewage is discharged into the sea, either directly through being deposited in rivers, or indirectly through run-off. In the Caribbean, for example, between 80 and 90 per cent of sewage is discharged into the sea without any treatment whatsoever (UNEP, 2000). Besides being a threat to health, these polluting discharges endanger the amount and the quality of marine food available for human consumption (PNUMA, 1999). Large quantities of insecticides, herbicides, fungicides

and other agrochemicals reach and affect species with which no contact was intended. Due to their high toxicity and tendency to accumulate in marine and coastal organisms, these substances form a serious public health risk. The same may be said of discharges of hydrocarbons and heavy metals coming from industry and transport. There is also a significant impact of pollution and the discharge of sediments onto the region’s coral reefs. This is particularly noticeable in the Caribbean, where two-thirds of the reefs are endangered and one-third are at a critical level (Bryant and others, 1998).

Degradation and coral loss in Jamaica The coral reefs on the northern coast of Jamaica present a classic example of degradation in coastal communities. These reefs have changed significantly since the 1950s, when the first description was given of the active growth of coral reefs in Discovery Bay. The combination of overfishing, degradation of water quality and loss of mangroves has left the reefs almost without fish and has particularly led to the disappearance of fish species that had been drawn to the coral because they feed on algae and coralline snails. When hurricane Gilbert hit Jamaica in 1988, it caused such damage to the reefs that they lost their original coral cover, which has not been restored. The reefs are now mainly populated by algae and little stony coral is left. Unlike coral, the algae do not form a stony skeleton, therefore they leave the coastal zone more vulnerable to the effects of violent storms. Furthermore, the algae do not provide the habitat necessary for many reef fishes, which also reduces the potential for recovery of fishery production. The general impact experienced is both a loss of environmental benefits and of ecological functions in the communities that inhabit the reefs. The reef communities lose stability, resistance and finally flexibility to subsist and recuperate when faced with disruption. In Jamaica, the environmental services of a whole productive reef have been lost. Sources: Hughes, 1994; PNUMA, 1989.

Oil pollution in the Greater Caribbean The Greater Caribbean is one of the world's most important oil-producing regions. The largest producers are Colombia, Mexico, Trinidad and Tobago, the United States and Venezuela. Most of the region's oil is shipped through a complex network of distribution routes. It is estimated that 90 per cent of petrochemical pollution in the Greater Caribbean comes from industrial sources such as refineries, three-quarters of which are on the Gulf of Mexico coasts.

Habitat conversion In general, the conversion of land for agriculture and urban and tourism use is the main cause of degradation in coastal habitats, including mangroves, estuaries and coral reefs. Mangroves are habitats for land organisms that include a variety of plants, invertebrates, reptiles, birds and mammals, and for aquatic organisms like fungi, algae, gastropods, clams, oysters, crabs and fish. The building of aquaculture tanks amongst mangroves, and other coastal uses, such extracting carbon and substances for dyeing leather, are causing very serious damage to important ecological functions, such as protecting the coast against erosion from waves, and incubating newly-spawned fish species that are vitally important for economic reasons, species such as shrimp, prawns and lobsters (UNEP, 2000). As well as erosion, the side effects include sedimentation and an increase in the discharge of nutrients into the sea (PNUMA, 1999). Concrete examples of critical damage to the region’s mangroves can be seen in Guyana (exploited for fuelwood), Virgin Islands (spoiled by sand extraction) and Suriname, Colombia and the Dominican Republic (used for breeding shrimp and fish) (PNUMA, 1999).

Hydrocarbon spills The production, transport and distribution of petroleum are also of great importance because of their potentially major impacts on the environment. In certain areas in this region – such as the Greater Caribbean (including the Gulf of Mexico) and some Brazilian coasts – the greatest pressure on the coastal-marine environment comes from the risk of spills from drilling, production and distribution of gas and oil. During the 1990s the Greater Caribbean — one of the world’s largest oil areas —produced about 170 million tonnes of petroleum annually, most of it from Colombia, Mexico, Trinidad and Tobago and Venezuela (PNUMA, 1994). Most of the oil is shipped from ports in the producing countries and is transported over a dense network of sea routes that carry 7 million barrels of crude oil every day (OLADE, 2001). Oil exploration and production activities are also going on in the depths of the Gulf of Mexico and off Brazil, constituting two of the world’s three principal deep sea production zones. PETROBRAS, the Brazilian state enterprise, has drilled the deepest: 1,853 metres for production and 2,443 metres for exploration (ONU, 2001). Of the ten largest oil spills in the world occurring before 1990, three happened in the Caribbean (Mexico, Tobago and Barbados). The worst damage, bigger than the better-known Exxon Valdez oil spill, came from the underwater explosion of the Ixtoc well in Campeche Bay. Other important spills occurred between 1991 and 1997 in Saint Kitts and Nevis, Puerto Rico and Venezuela. The largest was in Puerto Rico in 1994 with a

total spill of 375 million litres of diesel oil. More recently, in January 2000, a pipeline connecting the Duque de Caxias oil refinery to the terminal on Agua Island broke, resulting in a spill of 1.3 million litres of petroleum which affected an area exceeding 40 km2 in Guanabara Bay in Brazil (IBAMA, 2002). A year later, in January 2001, the tanker Jessica caused a spill of more than 726,000 litres of fuel, after a navigational error drove it aground close to the island of San Cristóbal in the Galapagos (AP, 2001).

Maritime transport Maritime transport is generally agreed to be a major source of marine and coastal pollution in Latin America and the Caribbean. Between 1970 and 2000, marine cargos in the region increased from 315.8 to 704.9 million tonnes (UNCTAD, 2001). By the mid-1990s, ports in the region had become the second most important destination after Asia for container transport from the United States; the Panama Canal, through which 234.5 million tonnes of cargo were transported in 2002, continues to be one of the world’s principal links for maritime trade (Hoffmann, 2000; ACP, 2003). With increased marine transport, it is believed that more and more pollution is coming from ships discharging (often intentionally) sewage, litter and hazardous chemical products. The United Kingdom and France, for example, both send radioactive fuel and wastes to Japan in armed convoys that voyage around South America or go through the Panama Canal (ONU, 2001). In addition, maritime transport is also the source of introduction of exotic and potentially invasive species, principally hiding in cargos and ballast. Cargos that in former times had introduced pests like rats and the plague to most parts of the world are today bringing crustaceans, land molluscs and insects that subsequently become agricultural blights (CSU, 2001).

Comercial exploitation of fishery resources One of the main direct threats to coastal and marine fisheries is the overexploitation of resources, including the accidental capture of species such as turtles, marine mammals, seabirds and other smaller but ecologically important species. In a recent study that established geographic priorities for marine conservation in the Greater Caribbean ecoregion, experts identified overexploitation as a threat to 34 out of 51 local production systems (Sullivan and Bustamante, 1999). Fisheries are located in three major types of habitat: continental platforms of coastal or shallow waters (where the main commercial pelagic or demersal fisheries are found); deep water (where large commercial fleets catch migratory species, generally in international waters); and coral reefs (of particular importance to artisanal fishing in the Greater Caribbean).

Chapter 2: State of the Environment in Latin America and the Caribbean, 1972-2002

Environment Outlook

As for volume, the greatest productivity in the region is in the southeast Pacific marine ecosystem where it is mostly small pelagic organisms (living in the water column without contact with the seabed, especially anchovy) that are fished off the coasts of Peru and Chile. Next come three ecosystems with similar volumes of fishing: the southwest Atlantic, where most catches are of demersal species (principally hake and squid that live on the seabed); next comes the central-west Atlantic, where coastal and shallow water species predominate, particularly lacha (Brevoortia tyrannus) in the Gulf of Mexico (all are caught by United States vessels) and the Caribbean using artisanal reef lobster and conch fishing; finally, tuna and small pelagic fishing is predominant in the central-east Pacific where, between 1950 and 1998, the tuna catch formed 59 per cent of the region’s total catch (Hoggarth and others, 2001) The total amount of marine fishing in the region’s surrounding waters reached its maximum level – over 26 million tonnes –in 1994 (forming close to 28 per cent of the world catch at that time). From 1985 to 1995, many South American countries doubled or tripled their catch and Colombia’s catch quintupled. But in 1998, regional fish catches fell sharply to a mere 13.8 million tonnes (15.6 per cent of the world total), recovering in 2000 to reach 22 million tonnes (22.9 per cent of world fishing catch) (FAO, 2002). These fluctuations in volume may be pointing to the dangers of overfishing. The greatest fluctuation has been seen in fishing small pelagic organisms in the southeast Pacific. Anchovy catches reached two peaks of 13.1 million tonnes in 1970 (the highest catch in the world

at that time) and 12.5 million in 1994, but then fell dramatically to only 94,000 tonnes in 1984 and 1.7 million in 1998. It is thought that the second decline had been exacerbated by the overfishing that had occurred between 1994 and 1996 (Hoggarth and others, 2001). Other small pelagic fish species (such as sardine and mackerel) suffered the same fate as the anchovy. Making up for anchovy losses, fleets from distant nations significantly increased their catch of other species until the United Nations Convention on the Law of the Sea entered into force in 1994. However, the recent collapse of fisheries in the southeast Pacific has also affected these species. The socio-economic impact of this collapse is notable, for example, in Chile, where exports of fishery products fell by 30 per cent between 1997 and 1998, and profits dropped by 10.6 per cent. There was also a reduction in other higher value species such as tuna which feed off the smaller species (Hoggarth and others, 2001). Although reef fishing is not commercially important, it has significant social and environmental repercussions. Many communities in the Caribbean make their living from the artisanal exploitation of reef species. As mentioned above, this has meant that overexploitation in the central Caribbean is now threatening two-thirds of the local production systems (Sullivan and Bustamante, 1999). The extraction of a growing number of organisms from the coral reefs’ food chain, needed to maintain the environmental quality of the reef systems, is also causing concern as it contributes to the overexploitation of valuable commercial species.

Aquaculture Although only in its early stages, regional aquaculture is already acquiring some economic importance. In 2001 total production was 1.1 million metric tonnes, with a value of US$3,900 million representing 2.9 per cent and 7.1 per cent of world production by volume and value respectively. In the same year, aquaculture produced 6.3 per cent of the region’s total fishery production value. In 2001, five countries were responsible for 84 per cent of total aquaculture production in the region: Chile with 51 per cent; Brazil 19 per cent; Mexico 7 per cent; Ecuador 6 per cent; and Peru 1 per cent (FAO, 2002). Two principal trends mark the evolution of regional aquaculture: first, the fall in Ecuador’s share, which dropped from 49 per cent in 1984 to 6 per cent in 2001, and second, the boom in Chile, which increased its share from 3 to 51 per cent during the same period (FAO, 2002). In spite of its drop in the regional share, aquaculture in Ecuador continues to be economically important. In 1997 its products represented 16 per cent of the total value of the country’s exports (oil included); the principal activity is the breeding of sea shrimp with an annual production volume that makes it the biggest producer on the continent and the second largest in the world after Thailand (CIDEIBER, 1999b). Chile holds ·

second place in world production of cultivated salmon and trout; productivity of salmon family species, in particular, has been sustained since 1993 (CIDEIBER, 1999a; CAPP, 2000). In Brazil – third in the region for volume of production – the most important species cultivated are shrimp and clams; in 2000, Brazil was the continent’s largest and world’s eight largest and producer (IBAMA, 2002). Unfortunately, regional aquaculture has been developed largely at the price of destruction of habitats such as mangroves, estuaries and salt marshes. It is essential to use these natural habitats for alternative economic and social activities such as fishing and tourism. Crops are also damaging ecosystems through the discharge of nutrients, pathogenic agents and hazardous chemical substances (BID, 1998). This explains why food production and disease control are the central problems affecting aquaculture. Ecuador is a regional example of the serious loss of mangroves and saltwater lagoons to the building of tanks to breed shrimp (CIDEIBER, 1999a).

Policy responses Presenting a policy response to the current situation of coastal and marine areas in Latin America and the Caribbean, the region has adopted many international, regional, sub-regional and national legal instruments and programming initiatives that cover a broad range of

problems. Most of the regional or sub-regional responses are based on a number of agreements related to the United Nations Convention on the Law of the Sea (UNCLOS), international conventions on maritime transport and conventions on fisheries.

Since its adoption in 1982, and especially since it entered into force in 1994, UNCLOS has been the general legal framework for international marine policy. This convention brings together most of the previously established pieces of international legislation and has been

104

Latin America and the Caribbean

ratified by 25 countries in Latin America and the Caribbean. A number of agreements have also been signed by specific countries at regional level (in these smaller areas) on matters such as protecting the marine environment, prevention of pollution from marine or terrestrial sources, and the management of commercial fisheries. These agreements include the Convention on the Protection of the Marine Environment and Coastal Areas of the Southeastern Pacific (1981), the Convention on the Protection and Development of the Marine Environment in the Greater Caribbean Region (1983), the Action Programme for the Southwestern Atlantic (1998) and the Convention on the Northeast Pacific (2002). For its part, the United Nations Food and Agriculture Organization (FAO) is supporting several regional bodies related to fisheries in which countries of Latin America and the Caribbean take part; several agreements are concerned with international tuna fishing, while others are more general. One of the main reasons for the development of regional policies is to respond to threats posed by marine and land-based activities. The first two – specifically regional – legal instruments adopted by Latin America and the Caribbean in this field were the conventions on the protection of the marine environment in the southeast Pacific (1981) and the Greater Caribbean (1983). Both are directed at mitigating and preventing pollution from marine or land-based sources and were preceded by the International Convention on the Prevention of Pollution from Ships (MARPOL) of 1973, and the protocol of 1978 (related to the convention on security of life at sea) which modifies and complements MARPOL. The latter is now known as MARPOL 73/78 for which the International Maritime Organization (IMO) is the depositary. The greatest advances in designing legal instruments on prevention of marine pollution have been made in the Caribbean. The Cartagena Convention of 1983 on the Protection and Development of the Marine Environment in the Wider Caribbean and its two protocols on oil spills and protected areas and wildlife together constitute the first framework convention for sub-regional action to manage marine and coastal resources (UNEP-CEP, 2003). The Convention covers all the countries with territories in the Caribbean, including North, Central and South America; the following seven countries in the region have not yet ratified the convention or its protocol on oil spills: Bahamas, Guyana, Haiti, Honduras, Nicaragua, Saint Kitts and Nevis, and Suriname. The protocol on protected areas and wildlife entered into force in 2000, and has been ratified by nine countries in the region: Colombia (1998), Cuba (1998), Barbados (2002), Panama (1996), Dominican Republic (1998), Saint Lucia (2000), Saint Vincent and the Grenadines (1991), Trinidad and Tobago (1999) and Venezuela (1997). A third protocol on terrestrial sources of pollu-

·

tion was adopted in 1999 with the signature of four American countries (Colombia, 2000; Costa Rica, 1999; Dominican Republic, 2000; the United States, 1999) and two European countries; however, no country has yet ratified it. This protocol deals with sewage from agricultural run-off and other unspecified agricultural sources. Countries in the region with territorial seas in the southeast Pacific (Peru, Ecuador, Colombia, Panama), the northeast Pacific (Mexico, Guatemala, El Salvador, Nicaragua, Honduras, Costa Rica, Panama, Colombia) and the southeast Atlantic (Argentina, Brazil, Uruguay) have also identified priorities for action to confront the challenges of protection and sustainable development of the marine environment. However, the relevant programmes and strategies are still in the early stages of implementation and a few are still being defined (Hoggarth and others, 2001; UNEP, 2003). In the southeast Pacific, the priorities are sewage, oils, heavy metals and persistent organic pollutants. In the northeast Pacific, one prime objective is to control the pollution that comes from the largest cities close to the coasts. In the southeast Atlantic, priority has been given to domestic and industrial sewage, and to the physical alteration of habitats and oils. As for specific threats from marine activities, the International Maritime Organisation’s world conventions have been strengthened by two sub-regional Memoranda of Understanding – one for Latin America and the other for the Caribbean – that permit countries to verify whether ships in their ports are complying with agreed standards (Hoggarth and others, 2001). In the Caribbean, special guidelines have been developed for inspecting small ships and boats that travel mainly within the region and are not subject to international standards, to ensure that they do not present risks to the environment or to human health. The Greater Caribbean has been declared a special area within the scope of MARPOL 73/78, with severe restrictions placed on waste discharges. Implementation has not been possible because the necessary infrastructure needed to collect and treat the waste is lacking (Hoggarth and others, 2001). UNCLOS is also important in the area of fisheries policies, in the fight against illegal fishing (especially of tuna). As already mentioned, UNCLOS seeks to articulate other regional agreements or action programmes on this theme, such as those promoted by FAO. One important recent international instrument in this field is the agreement on the conservation and management of highly migratory fish populations (FSA, Fish Stocks Agreements), that entered into force in 2001 and is now strategically important for conserving regional fishery resources. However, so far only the six following countries in Latin America and the Caribbean have ratified the FSA: Bahamas, Barbados, Brazil, Costa Rica, Saint Lucia and Uruguay (UNCLOS, 2001).

It is important to note that most fishing countries in the region have regulations governing access to their main fishing grounds, and several countries have legislation to control illegal open sea fishing. It is generally a matter of “command and control” procedures, and the use of economic instruments is still limited. Mechanisms tare now used to regulate access include the issue of licences (limiting, for example, the total number of vessels or of fishermen), the declaration of closed seasons, and the control of inputs (such as limiting engine size). Cuba and Guyana may be mentioned as examples in the Caribbean. Cuba’s Fishery Law has been in force since 1996 and establishes mandatory licences for fishing, defines offences and sets penalties. Legislation in Guyana imposes an obligation of compliance with conservation and regulatory measures for vessels before open-sea fishing licences are granted (ONU, 2001). Peru, Argentina and Chile are also active in South America. Peru’s laws permit foreign vessels to fish within its national jurisdiction if they buy fishing and navigation permits, provided they comply with fishery regulations. Most permits are awarded for giant squid fishing. In 1998 Argentina signed its Federal Fisheries Law (No. 24922), creating a Federal Fisheries Council that prescribes fisheries policy, annual catch quotas, issues fishing permits and regulates an “invitation to participate” system. The Law has not been fully applied because of jurisdictional conflicts. Finally, in Chile the fishery sector is highly regulated, mainly by economic instruments. There are individual and transferable catch quotas for new fish species (such as deep-water cod) and for species in recovery (such as red and yellow prawns). Property rights are awarded by public auction, (CAPP, 2000). Besides this, the Chilean Fishery Law prohibits all unloading, the taking on of supplies and other services in national juris-

diction zones by vessels whose open sea activities are deemed to damage the environment, and also regulates all fishing within the country’s exclusive economic zone (ONU, 2001). Other regionally important agreements exist, such as programmes or multilateral projects, including several administered by UNEP (such as the regional seas programme, a programme on the protection of the marine environment from land-based activities and the project on global assessment of international waters). A world project also exists to eliminate barriers to the implementation of ballast water controls and management measures in developing countries, proposed by the International Maritime Organization for the period 2000-2002. The international network for action on coral reefs supported by the United Nations Foundation is another important effort to contain their degradation. Finally, the Caribbean Planning for Adaptation to Global Climate Change project is promoting actions to assess vulnerability (especially regarding the rise in sea level), plans for adaptation and development of appropriate capacities. Marine and coastal biodiversity is an emerging topic of great importance. Not long ago the initiative here passed to the Conference of Parties to the Convention on Biological Diversity. In 2000, the conference adopted a work programme in this field with five core subjects: integrated marine and coastal regulation; protected marine and coastal zones; live marine and coastal resources; mariculture and exotic species; and coral reefs (ONU, 2001). This new approach of integrated marine and coastal regulations highlights the policy limitations on regional development in this field. The coastal-marine zone is a highly sensitive area where many ecosystems interact harmoniously and are affected not only by what happens at sea but also by land activities. Due to the strong

Programmes to protect regional seas and the marine environment from land-based activities In 1995, when more than 100 countries adopted the World Action Programme for the Protection of the Marine Environment against Land-Based Activities (PAM), UNEP was invited to act as its secretariat. The Programme was conceived as a conceptual and practical orientation source to which national and regional authorities could have recourse when developing and applying regional and sub-regional agreements, and to mobilise international collaboration to prevent or mitigate the negative impact of land-based activities on the marine environment. UNEP also directs the Global Assessment of International Waters (GIWA), an environment project which has been developing a global assessment of 66 transboundary marine water areas since 1999. GIWA is concentrating on five aspects: shortage of freshwater, pollution, conversion of habitats and communities, non-sustainable exploitation of fishing and other natural resources, and global environment change Sources: PNUMA-ORPALC, 2003; GIWA, 2001.

pressure of human settlement and economic activity, a comprehensive policy design is needed within the “integrated coastal management” model.

end, it is indispensable that national focal points be established to assume responsibility for implementing and accepting such agreements.

Although the region has made progress and a legal and institutional framework exists to implement this model, it has not yet been possible to develop an integrated approach to the problems on an appropriate geographical scale (Hoggarth and others, 2001). There is still a need for the sub-regional integration of policies and institutional arrangements, stressing the protection of marine fisheries (especially for over-harvested species) and of endangered non-commercial species, with efforts devoted to the control of pollution and degradation of essential marine habitats. An overall view is needed for the simultaneous consideration of watersheds and coastal zones, with emphasis on protecting fishery resources in the early stages. In addition, recognition must be given to the services to the environment afforded by coastal-marine areas, including the mitigation of natural threats (see section on Disasters).

A serious weakness here is lack of information on international agreements, and on the state of the environment and actions to conserve it. As far as the agreements themselves are concerned, better understanding is needed of what benefits they will bring and what they will cost. In the case of managing the environment, regional environmental monitoring processes that collect basic information should be directed towards assessing environmental conditions and monitoring activities in a way that will help the implementation of policies designed to achieve sustainable development of coastal and marine areas.

More specific action is also required to focus attention on the impact of land-based activities on coastal areas, especially the inclusion of watershed and coastal management in preventive and mitigation policies. Existing mechanisms must be strengthened to define policy priorities in relation to environmental protection and sustainable development, as well as conciliating interests between nations and different stakeholders. To this

Strategic problems arise from the limited financial, technical and human resources available to national institutions, especially in small countries and dependent territories. International support offered by multilateral environmental agreements must be properly mobilised if the commitments and priorities contained in such agreements are to be articulated (Hoggarth and others, 2001).

Atmosphere

T

he most serious atmospheric problems in Latin America and the Caribbean are air pollution, de pletion of the stratospheric ozone layer and the process of climate change, as well as their impacts on the health of the region’s population and ecosystems. As much as one-fifth of the regional population is exposed to air pollutants that surpass recommended limits (CEPAL, 2000a) mostly in the mega cities and large metropolitan areas, but spreading to medium-sized and smaller cities. On a more global scale, but nonetheless with substantial local impact, the depletion of the stratospheric ozone layer is largely affecting the southernmost portion of Argentina, Brazil, Chile, and Uruguay, while climate change is having widespread environmental and socio-economic effects throughout the region, especially in the Caribbean.

Air pollution Atmospheric emissions from the transport, industrial and agricultural sectors, waste disposal processes, forest fires, and domestic sources, are the leading causes of degraded air quality in Latin America and the Caribbean. In combination with specific local topographic and meteorological conditions that aggravate their effect, these emissions have a very significant health impact on both rural and urban populations. Some of these pollutants have a transboundary, and even transcontinental origin, such as emissions created by human activities in cross-border areas, smoke from forest fires, or the dispersion of suspended particles from Africa to the Caribbean.

Outdoor air pollution Air pollutants are usually classified in three categories: suspended particles, gases and odours (WHO, 2000). In the urban centres in Latin America and the Caribbean, the most prevalent air pollution is related to high concentrations of particles and ground-level ozone (PAHO, 2002). Particles with a diameter of less than 10 micrometers (MP10) are a cause for concern (WHO, 2000). Among these, those larger than 2.5 micrometers are generally composed of earth and minerals (carbon, asbestos, lime, cement or metals such as zinc, copper, iron, lead), and tend to precipitate quickly. Particles smaller than 2.5 micrometres are generally carbons, sulphates and nitrates from burning biomass and diesel, or in chemical ozone formation reactions, sulphur di-

109

oxide oxidisation and nitrogen oxides produced from burning fossil material. These smaller particles remain in the air longer and may more easily become deposited in the human respiratory system. In large metropolitan zones like Sao Paulo, Santiago, Chile, and the Valley of Mexico, both the maximum 24-hour MP10 concentrations and their annual averages are above the existing standard, although in Santiago the annual averages dropped between 1989 and 1999 (PAHO, 2002). Many smaller cities in the region were above the standard, including Guadalajara and Monterrey (Mexico) and the capitals of Colombia, Costa Rica, Cuba, Ecuador, El Salvador, Guatemala, Honduras, Nicaragua, Panama and Peru (PAHO, 2002). Gaseous pollutants include ozone, sulphur or nitrogen compounds, carbon monoxide, hydrocarbons and other volatile organic compounds (WHO, 2000). As to ozone pollution, Sao Paulo, Santiago, and the Valley of Mexico showed decreasing trends of between 20 and 30 per cent at the end of the 1995-2000 period for which systematic measurements were made. However, in 1999-2000 concentrations of ozone in the three metropolitan areas remained above the norm for between18 and 88 per cent of the time, and Mexico City experienced the most serious problems (PAHO, 2002), Vehicular and industrial emissions are significant contributors to outdoor air pollution in Latin America and the Caribbean. They have significantly increased in recent decades, and originate mostly in large and some medium-size metropolitan areas and industrial zones. Other important outdoor pollutants are produced by the inadequate disposal or incineration of solid waste, aerial spraying of crops, wind erosion and the combustion of biomass for fuel. Fossil fuel combustion in the transport sector is particularly problematic. For example, Mexico City and Buenos Aires register 75 and 70 per cent respectively of emissions from this source (INEGI, 2000; PAHO, 1998). In Santiago, Chile, the most significant sources of air pollution are urban transport and small and mediumsized enterprises (IMO, 1995). The transport sector in that city is responsible for up to 92 per cent of carbon monoxide, 71 per cent of nitrogen oxide and 46 per cent of volatile organic compound emissions (CAPP, 2000). Air pollution from road transport is made worse because of the high average age of motor vehicles, the accelerated growth of the fleet, insufficient or inadequate public transport and the horizontal expansion of cities, with people living far away from where they work, increases transport distances, as well as local topography and meteorological conditions in cities like Mexico and Santiago, where the surrounding mountains limit the dispersion of polluted air. In Mexico City the number of vehicles quadrupled between 1970 and 1996, whereas in Jamaica it doubled between 1993 and 1998 as it did

in Santiago between 1990 and 1999, and in Trinidad it grew by 18 per cent (Schteingart, 1987; CEPAL, 2000c; UNEP, 1999a; PAHO, 2002). In some cases, the increase was due to the increased importation of used cars.

tary landfills (and even in open-air dumps) that do meet emission standards for biogas emissions or leachate control (see section on Urban areas).

Major oil-producing countries such as Brazil, Ecuador, Mexico and Venezuela are also affected by oil refinery emissions. Other mining activities degrade local air quality in countries such as Bolivia, Brazil, Chile, Colombia, Dominican Republic, Jamaica, Peru, Suriname and Venezuela. Heavy metals from petrol combustion and mining activities (lead, mercury) are also significant in polluting air masses (UNEP, 1999a; PAHO, 1998).

In Sao Paulo and Brasilia controlled incineration is used for only one per cent of the waste and there is none in Mexico City, Rio de Janeiro or Santiago. Furthermore, in many rural areas in the region solid waste is commonly burnt, without any control. Both controlled and uncontrolled incineration release dioxides, shown to be cancerous, into the atmosphere; uncontrolled practices can raise the concentration of emissions by several orders of magnitude, depending on the contents of the material to be burnt and on combustion conditions (Lemieux and others, 2000).

The use of fossil materials to generate electricity produces emissions of 27 tonnes of mercury annually in South America alone (less than the levels in Asia and Africa, from 860 and 197 tonnes annually (UNEP, 2002a). In the metallurgic area of Vinto (close to Oruro, Bolivia), residents’ blood and urine show concentrations of lead and arsenic above the risk levels defined by the United States Environmental Protection Agency (PAHO, 1998).

In peri-urban and rural areas, chemical compounds used to fumigate agricultural crops are an important source of air pollution. Exposure to pesticides occurs through inhalation and skin contact, affecting farm workers and populations close to agricultural land, as seen in Ecuador, Colombia and Nicaragua (WRI and others, 1998).

In the case of solid waste atmospheric emissions, two potential sources are biogas from sanitary landfills and incineration dioxins. Practically all final urban solid waste disposal in the region is in sanitary landfills, while in some countries controlled incineration is only used for hazardous hospital waste (PAHO, 1998). However, in the 33 large cities for which reliable information is available, 43 per cent of solid waste is deposited in sani-

Large dust clouds cross the Atlantic every year from the north of Africa and affect North America, Central America, the Caribbean and the northeast Amazon basin: a type of pollution not previously identified. it is feared that they might worsen respiratory infections (mainly asthma), create new public health risks by acting as hosts for bacterial, viral and fungi spores and add to coral reef degradation (USGS, 2000; Griffin and others, 2001).

Air pollution from forest fires Forest fires may destroy up to 50 per cent of the woody surface biomass, with potentially serious effects on fauna. In addition, they release carbon into the air, making global climate change worse. Finally their direct impact on the economy and health in Mesoamerica and South America has increased, even on populations hundreds of kilometres away from the fires (see section on Forests). In 1998, smoke and air pollution from fires in Guatemala, Honduras and Mexico reached a large part of the southwest of the United States, obliging the government of Texas to issue a health warning. In 1999, smoke from fires in Mato Grosso, Brazil, polluted the air in Paraguay, and the smoke produced in Paraguay polluted the air in Argentina. These problems reveal the transboundary dimension of the pollution caused by forest fires and show the need for a regional action plan to control and combat fires in Latin America and the Caribbean. Source: UNEP, 2000; Cochrane, 2002.

Chapter Burning biomass (from agroindustrial processes, domestic usage and forest fires) is another important source of air pollution. It is calculated that about 40 per cent of the agricultural waste produced annually in developing countries is burnt on the land.

Indoor air pollution Although less research has been done on indoor air pollution, it is of great importance in the region. It is caused by the emission and circulation of both biological particles (pollen, mites, insects, microorganisms) and inorganic particles (different types of smoke, including tobacco smoke, lead, carbon oxides, asbestos, synthetic chemical compounds) (WHO, 2000), A major determinant of the level and type of indoor air pollution is the energy source used to cook and to light or heat houses and buildings. Globally, 50 per cent of households use biomass combustion for these purposes. In the most urbanised countries in Latin America and the Caribbean, domestic biomass combustion is much less than in other parts of the world, but even so a fifth of the population uses biomass as the main household fuel (WRI and others, 1998). Of the region’s total energy consumption in 1997, traditional combustion accounted for 15.7 per cent (close to the average in developing countries); however, in countries such as Peru and Brazil the traditional combustion rates were 24.6 and 28.7 per cent respectively, while in Paraguay, Costa Rica, Honduras, Guatemala and Haiti consumption was above 49 per cent (UNDP, 2002). Indoor pollution is worse where there is urban poverty. Overcrowding and lack of physical space preclude proper ventilation, and burning biomass for cooking affects those who stay indoors for long periods – usually women, children and the elderly. Studies in Colombia and Mexico indicate that women who use biomass for cooking are three to 75 times more likely to contract chronic lung disease than the average person,

depending on the length of exposure (WRI and others, 1998).

Regional impacts and responses More than 80 million people in Latin America and the Caribbean are permanently affected by air pollutants. In large metropolitan areas such as Sao Paulo, Rio de Janeiro, Santiago and Mexico City, air pollutants exceed the maximum limits recommended by the WHO (ECLAC, 2000a). In addition, pollution is increasing in many smaller metropolitan areas and even in mediumsize cities. This is a consequence of the growing pressure of transport and industry, and the lack of appropriate regulatory, monitoring and control action. Exposure to air pollutants has critical effects on health, as well as significant economic impacts, due to the cost of medical treatment and considerable losses in productivity from worker absenteeism (O’Ryan, 1994). Some estimates suggest that air pollution in the region is the leading cause of about 2.3 million cases annually of chronic respiratory illnesses in children, and of 100,000 cases of chronic bronchitis in adults (CEPAL, 2000a; 2000b), Concentrations of sulphur dioxide in Santiago, Chile, and of nitrogen dioxide and tropospheric (lower atmosphere) ozone in Mexico City have been found to have a high correlation to respiratory infections, the acceleration of pulmonary diseases and ageing of the lungs (PAHO, 1998; WHO 2000). Exposure to lead, even at a low level, has an adverse impact on human health, including systematic (gastrointestinal problems, anaemia, hypertension or hearing loss), nervous system (hyperactivity), developmental (learning problems), reproductive, genotoxic and carcinogenic effects (ATSDR, 1999). In Mexico, the concentration of lead in the bones of the mother has a negative effect on the weight of the newborn, as does the level of lead in the blood on the intellectual capacity of children between nine and 12 years of age (WHO, 2000).

Air pollution also has a considerable impact on mortality. Estimates for Sao Paulo and Rio de Janeiro indicate that it leads to about 4,000 annual cases of premature death, with observed links in Rio de Janeiro and Cubatao between child mortality from pneumonia and a decrease in infant lung functions (CETESB, 1992; WHO, 2000). Other studies suggest that higher concentrations of suspended particles are connected to increases in daily mortality rates (in Chile and Mexico) and particularly with more adult mortality over the age of 65 (in Brazil) (WHO, 2000). It is estimated that a reduction of 10 per cent in tropospheric ozone and suspended particles, by 2020, would prevent more than 37,000 deaths in Mexico City and 13,000 in Sao Paulo (The Economist, 2002). It is important to consider the effects of indoor air degradation in particular, because people are exposed to it inside their dwellings. Smoke from burning biomass, in particular, contains significant quantities of pollutants, such as carbon monoxide, suspended particles, volatile organic compounds and nitrogen oxides and is associated with various ill effects on human health: irritation of tissues, chronic pathologies and various types of cancer. There are more than 2.5 million annual premature deaths in developing countries as a result of prolonged inhalation of these pollutants (WHO, 2000). Universities and ministries of health in the region began to measure emissions of air pollutants in the 1950s. In 1967, the Pan-American Health Organization (PAHO) created a regional monitoring programme, which by 1973 had 88 stations in 26 cities in 14 countries: the Pan-American Normalized Monitoring Network for Air Pollution. In 1980 the network was brought

within the United Nations Environment Programme’s Global Environmental Monitoring System. There are now two regional programmes on air quality improvement in Latin America: the World Bank’s Clean Air Initiative for Latin American Cities (with projects in Lima and Callao, Mexico City, Rio de Janeiro and Buenos Aires) and the Central American Pure Air Programme, financed by the Swiss Development and Cooperation Agency (OPS, CEPIS, 2000). Cities with air quality measuring systems have introduced new technologies to expand their capacity to prevent episodes exceeding the permitted thresholds. Mexico City, Santiago and all large Brazilian cities have established standards similar to those of the World Health Organization, although they are more tolerant to burning coal and sulphur dioxide (CEPAL, 2000c). An increase in emissions may be offset by taking old vehicles out of circulation, raising the price of petrol and switching to alternative fuels (such as hydrated ethylic alcohol or liquid or natural gas instead of petrol), Several of these measures have been promoted in Brazil since the 1980s and in Mexico since the mid1990s (UNEP, 2000; INEGI, 1998). In addition, most countries in the region are phasing out the use of leaded gasoline. By the end of 2001, there were 23 countries in Latin America and the Caribbean with lead-free petrol and, compared to 1990, the region as a whole had achieved a reduction of 90 per cent in atmospheric emissions of lead from petrol (ARPEL, 2001). Nevertheless, some pollutants are more difficult to reduce than others. For example, in 2000, in four of six Central American capitals, annual average concentrations of suspended particles from mobile sources (total and less than 10 micrometers in diameter) exceeded international norms (Swisscontact, 2001).

Pollution reduction: success stories Brazil In Brazil, action to control and monitor air pollution was first developed and implemented in the city of Sao Paulo, and then in Rio de Janeiro and Rio Grande do Sul. In 1976, federal air quality regulations strengthened alreadyexisting controls in the pioneering cities, and extended them to others, applying WHO guidelines for suspended particles, sulphur dioxide, carbon monoxide and photochemical exidants (such as ozone). Local air pollution controls began by prohibiting domestic garbage incinerators in residential buildings and open-air burning of rubbish in urban areas, and controlling emissions of smoke, first on stationary sources and later on diesel vehicles. Controls on diesel vehicles led to the establishment in 1986 of the principal national automotive air pollution control programme (PROCONVE) which, since 1993, has been backed by a federal law. PROCONVE has established emission controls for vehicles of otto and diesel cycles, resulting in gradual reductions for the new otto cycle emissions by 92 per cent overall (including 97 per cent for carbon monoxide, 94 per cent for hydrocarbons and 86 per cent for nitrogen oxides). In 1990 air quality standards were reviewed to improve air pollution controls for stationary sources, to regulate critical air pollution episodes and to establish preventive criteria regarding external combustion processes (such as thermoelectric generators and furnaces) in conservation areas and non-saturated areas (Teixeira, 2001). The second most important line of action in controlling vehicular emissions was the introduction in 1975 of anhydrous alcohol (known as ethyl alcohol or gasohol) together with incentives for the production of exclusively gasohol-run vehicles. By the mid-1980s, 90 per cent of vehicles sold used gasohol, reducing emissions by 20 per cent overall, and with very substantial drops in lead, bromide and chloride, for which petrol motors were the main source. Although manufacture of gasohol vehicles declined in the 1990s to 0.1 per cent of total sales, due to lack of state policies to guarantee production of the fuel, the government has since renewed incentives for this technology (see box on Page 189 in chapter 3). © R. Burgos

Chile In Chile, the Plan to Decrease Air Pollution in the Metropolitan Region was prepared in 1990 and extended in 1997. The plan's strategies included regulating household and industrial emissions, introducing taxes, removing highly polluting buses, controlling bus circulation and emissions, introducing automobiles with catalytic converters, improving fuel quality, and paving streets (O'Ryan and Larraguibel, 2000). In addition, the government introduced a system of transferable pollution permits, which industries could buy or sell to reduce their total emissions (The Economist, 2002). An assessment of the plan's implementation revealed that almost 60 per cent of proposed actions were successful (CEPAL, 2000d). As a result, both the emission of particles and the number of days when alerts were sounded or emergencies declared have been reduced significantly. Between 1989 and 1999 concentrations of suspended particles, for example, fell by 24.1 per cent for those smaller than 10 micrometres and by 47.4 per cent for those smaller than 2.5 micrometres (CAPP 2000). The same system that reduced the concentration of suspended particles is now being applied in preliminary tests on other pollution sources. In the framework of a public-private clean production committee, 46 metallurgy companies have established an agreement to promote the adoption of clean production measures, particularly in relation to air pollution and solid waste management.

Pollution reduction: success stories (continuation) Mexico In Mexico, the Comprehensive Programme Against Air Pollution in the Valley of Mexico began in 1990 with a view to improving the air quality of that metropolitan area. The 1995-2000 Programme to Improve Air Quality in Mexico City included initiatives such as: · · · · · · ·

the establishment of the Valley of Mexico Environmental Trust Fund, to finance air quality improvement programmes through a tax on petrol; the Automatic Environmental Monitoring Network;. environmental emergency programmes; a Day Without a Car vehicle restriction programme; an epidemiological surveillance system; a reforestation programme; environmental education in the Mexico City metropolitan area.

Assessments for the period 1991-1999 reveal that the concentrations of carbon monoxide, sulphur dioxide and lead tended to remain below the limits established. In the case of ozone, although there is a trend to reduce concentrations, they are still above the standard on many days throughout the year; the concentration of suspended particles, on the other hand, rather increased in the period 1995-2000 (SEMARNAP, 2000; PAHO, 2002). Improving air quality in Mexico City -in spite of persistent difficulties- required institutional capacity building; improvements in regulatory, communications and citizen participation mechanisms; and strengthened integration of metropolitan policies. Citizen participation has proved to be of fundamental importance (CEPAL, 2000b).

oxide was below the norm in only two cities, while tropospheric ozone and lead exceeded the norms in the other two.

Impact of ozone depletion and regional responses In September 2000, the hole in the Antarctic ozone layer reached its maximum recorded size of approximately 28 million square kilometres, more than 2.5 times greater than the average recorded between 1979 and 1992. At the end of September, minimum ozone levels were also the smallest ever recorded; half the average between 1964 and 1978, before the hole appeared (WMO, 2001; NASA, 2001). The hole in the ozone layer has a major regional impact in Argentina, Brazil, Chile and Uruguay. Official reports in Argentina, for example, indicate that Tierra del Fuego and (to a lesser degree) the south of Patagonia, were under the hole for 10 days in 2000, with ozone values among the smallest recorded (Canziani, 2000). This produced ultraviolet radiation levels “similar to those in Buenos Aires in summer”.

Global production and consumption of chlorofluorocarbons (CFCs) are the principal causes of stratospheric ozone depletion, and have been under control since the Montreal Protocol entered into force in 1987. The protocol’s implementation in developed countries has signified a dramatic reduction — almost 95 per cent – in annual production (from more than a million tonnes in 1986 to a little over 46,000 tonnes in 1998) although it increased slightly in 1999-2000. On the other hand, production in developing countries continued to increase (especially in Asia where it reached three-quarters the amount of total production in developing countries) and doubled between 1986 and 1995 (from 56,068 to 115,185 tonnes) until it started to decline in 2000 (UNEP, 2002c). Global CFC consumption dropped from 1,078,634 tonnes in 1986 to 148,151 tonnes in 1999 (there are no data available for 2000 on consumption in China; the 1999 figure was 42,983 tonnes) (UNEP, 2002c). This reduction of more than 85 per cent mostly occurred in developed countries and explains why, in 1999, total consumption in developing countries was five times greater than in developed countries.

In Latin America and the Caribbean CFC production between 1986 and 2000 reached an accumulated total of 342,034 tonnes, equal to 5.8 per cent of global production and approximately a third of total production in developing countries during the same period (UNEP, 2002c). Mexico, Brazil, Venezuela and Argentina (in descending order) were the only producers in the region, with Mexico and Brazil accounting for 72.8 per cent of total production in that period. By the end of the period, the four countries had been able to reduce their annual CFC production. As a result, regional CFC production in 2000 was 44 per cent less than the total in 1985. Brazil stopped producing CFCs in 2000 (UNEP, 2002c). Accumulated regional consumption of these substances during the period, at 391,929 tonnes, was slightly above production. In 2000, regional consumption was only 61.2 per cent of the 1986 figure. The main

consuming countries were again Brazil, Mexico, Venezuela and Argentina (in descending order), with 78.9 per cent of total regional consumption in 2000. In Brazil, the time limit for eliminating CFC consumption is more restrictive than the general agreements in the Montreal Protocol, although it has been extended from January 2001 to 2007 (three years before the deadline foreseen in the protocol) in an effort to avoid “forcing out small and medium-sized enterprises that do not have enough time to adapt”, according to officials of the Ministry of the Environment (Campanili, 2000). Imports of CFC-12 (dichlorofluoromethane) in Brazil are being gradually restricted, beginning with a reduction of 15 per cent in 2001, and 35 per cent in 2002, until they are totally eliminated in 2007. Imports of CFC-11 (trichlorofluoromethane) are only permitted to companies with projects to convert to CFC-11-free technologies. Officials in the private environmental sector be-

Ozone risks in Punta Arenas and Santiago The hole in the ozone layer is not a pleasant topic for the 120,000 inhabitants of Punta Arenas, the southernmost city of Chile and of South America. However, in 2000 it was discovered that, contrary to what had been assumed, the hole is a greater health risk to residents in Santiago, 2000 kilometres to the north, where the incidence of skin cancer is much higher. Residents in the extreme south, despite receiving more unfiltered solar radiation, are less affected because of the hostile and windy climate —in October winds of 120 km/hour have been recorded— life in Punta Arenas takes place indoors, in heated homes, and people are less likely to be out in the open with head and arms uncovered.

Global efforts to reduce ozone depleting substances In 1974, the first study was published linking stratospheric ozone destruction to the release of chlorine in the production of foams and refrigerants. The main ozone-depleting substances and ozone-generating industrial processes include: l

chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons in commercial and household refrigeration equipment, aerosol propellants, foaming agents and pre-polymers for insulation and other applications;

l

solvents such as trichloroethane and methyl chloroform for cleaning metals;

l

halons found in portable and fixed fire extinguishers;

l

hydrobromofluorocarbons;

l

methyl bromide in products for spraying crops and goods for export.

Although 90 per cent of emissions of ozone-depleting substances occur in Europe, North America and Japan, they spread out over the entire world's atmosphere in 12 to 24 months. The chlorine and bromide in these emissions remain latent when they are over Antarctica during the southern hemisphere winter because of its peculiar atmospheric characteristics. When light returns to the south pole in the spring (September-November), these compounds rapidly destroy the existing ozone, which has decreased to levels up to 60 per cent less than those observed before this phenomenon appeared in the 1980s (WMO and UNEP, 1998; 2002). Global loss of stratosphere ozone has caused an increase of between four and seven per cent in ultraviolet B radiation (UV-B) throughout the year in the mid latitudes of the northern hemisphere and six per cent in the same latitudes in the southern hemisphere (UNEP, 1999b). However, during the southern spring, the increase in UV-B radiation is much greater — about 130 per cent— as a consequence of the loss of ozone. In recent years, there have also been unusually low ozone concentrations in high northern latitudes although not as low as in the southern latitudes believed to be the result of extraordinarily severe stratospheric winters in these zones (WMO and UNEP, 2002). In 1977, the first conference of experts on the depletion of the ozone layer was convened by UNEP, and the first global action plan in this field was adopted, leading to the prohibition of certain CFC-emitting products. These initiatives gave rise to the Vienna Convention on the Protection of the Ozone Layer (1985) and the Montreal Protocol on Substances that Deplete the Ozone Layer (1987), in which the developed countries assumed commitments to reduce, by 1999, production and consumption of CFCs and other controlled substances by 50 per cent of the 1986 levels. Subsequent amendments to these agreements (London, 1990; Copenhagen, 1992; Montreal, 1997; and Beijing, 1999) have increased the list of controlled substances and reduced some of the periods for phasing them out. As 2002 drew to a close, 184 countries had ratified the Vienna Convention, 183 countries had ratified the Montreal Protocol, while the London, Copenhagen, Montreal and Beijing amendments had been ratified by 163, 141, 83 and 36 countries, respectively (UNEP, 2002c). The 1997 conference established an ozone layer action plan, coordinated by UNEP and the World Meteorological Organization, which serves as a framework for many activities in this field. In the Montreal Protocol, countries with annual per capita CFC consumption rates prior to 1999 of less than 0.3 kilograms are classified as Developing Countries. These countries, including all Latin America and Caribbean countries, were given a 10year grace period to put the control measures in place, provided the financial assistance and technology transfer actions also agreed to in the treaty had been complied with. For these countries the protocol established a freeze on CFC consumption and production in 1999 at 100 per cent of the annual average between 1995 and 1997. Together with subsequent amendments to its agreement, the protocol has also set time limits to freeze the consumption of halons (2002), methyl bromide (2002) and other CFCs (2003) and to reduce consumption of ozone-depleting substances by 2005 (85 per cent for carbon tetrachloride, 50 per cent for CFCs and halons, 30 per cent for trochlorethane, and 20 per cent for methyl bromide). Estimates indicate that the Montreal Protocol's degree of implementation to date will allow stratospheric ozone concentration to be restored to its pre-1980 levels by the year 2050, eliminating the hole in the ozone layer over Antarctica (UNEP, 1999b). Although the combined levels of ozone-depleting substances in the troposphere (lower atmosphere) have been decreasing since 1994, it was only recently that the levels of chlorine have reached - it seems - the maximum level in the stratospheric layer, while the level of bromine continue to rise in the layer (WMO and UNEP, 2002). It is estimated that their maximum ozone-depleting levels will be reached in the first or second decade of the 21st century (WMO and UNEP 1998). Other concerns are related to the ozone-depleting impact of increasing tropospheric concentrations of bromide from industrial halons and methyl bromides (WMO and UNEP, 2002). Recent evidence suggests that these concentrations may have more than doubled since the 1950s and are still growing at an annual rate of about three per cent (two-thirds of the reported rate in 1996). At present, the fractional contribution of bromine to total polar ozone loss ranges from 30 to 60 per cent, and will continue to increase relative to chlorine until the current upward trends of the bromine source gases reverse.

lieve that a halt to Brazilian CFC production could encourage smuggling for use in refrigeration systems that still depend on this gas; such illegal imports supplied about 15 per cent of total CFC consumption in 2000 (Campanili, 2000). The Mexican strategy to reduce CFC consumption includes agreements with industry, regulating imports and exports of controlled substances, developing technical training programmes and implementing clean technologies. Projects have included domestic and commercial refrigeration, solvents, foams and both central and motor vehicle air conditioning, and many such projects have been supported by international agencies like the World Bank, the United States Environmental Protection Agency, UNDP and UNEP (SEMARNAP, 2000). In the region two other substances, halons and methyl bromide (used basically in fire extinguishers and agriculture, respectively), are among the main ozone destroyers, although they are not produced in the region and consumption is relatively low (UNEP, 2002c). In the case of halons, which it was agreed to freeze in 2002, only Mexico and Belize reported any consumption in 2000. In the region as a whole, annual halon consumption was reduced by 81.2 per cent in the period 1986-2000. The consumption of methyl bromide was also agreed to be frozen in 2002, but here the situation is not so encouraging. During the 1991-2002 period, the region consumed 11 per cent of the global volume, with the last year representing 16 per cent of the total. Regional consumption tripled between 1991 and 1994, although in 2000 it dropped to double that of the first year. Sixteen countries were still consuming the ozone-depleting substance in 2000. Mexico, Brazil, Costa Rica and Argentina (in descending order) accounted for 72 per cent of accumulated consumption during the period.

tation of the Protocol and the Global Environment Facility. In the case of Latin America and the Caribbean, the Regional Office of UNEP acts as one of the programme’s executing agencies. It is responsible for promoting regional networks and refrigeration management plans, and for supporting 22 of the ongoing 33 institutional strengthening projects. The Multilateral Fund’s resources have played an important role in these activities. The actions reviewed, however, are not enough fully to solve the problem. The present state of production and consumption of ozone-depleting substances and regional trends highlight the major challenges to meeting the objectives of the Montreal Protocol (UNEP, 1999c). One such challenge is that, taking 1995-1997 production as a basis for the agreed elimination timetables, the duplication in production between 1986 and 1997 increases the permitted levels until the year when they are to be totally eliminated. It should also be noted that, in spite of the virtual elimination of CFCs in industrialised countries, illegal imports of these substances to these countries have grown and are estimated to be between 20,000 and 30,000 tonnes annually (UNEP, 1999c). These illegal imports provide an incentive for developing countries to produce more. The second major challenge is the growth in tropospheric concentrations of bromine, from industrial halons and methyl bromide, which to some extent reverts the success in controlling CFCs (WMO and UNEP, 2002). Production of halons fell in developed countries from 186,168 to 1,270 tonnes during the 1986-2000 period, but increased in developing countries from 11,290 to 49,467 tonnes in 1986-1997, before falling to zero in 2000 (UNEP, 2002c). Production of methyl bromide, on the other hand, fell from 39,601 to 26,086 tonnes in developed countries during the period 19912000. Production in developing countries has always been a small fraction of the total (less than four per cent). Although it has already been pointed out that these substances are not produced in Latin America and the Caribbean, there is considerable consumption of methyl bromide and it is now almost a seventh of the global total.

At the beginning of 2003, the 33 countries in the region were parties to the Vienna Convention and the Montreal Protocol; 31 had ratified, acceded to or accepted the London amendment (1990): 30 were parties to the Copenhagen amendment (1992) and 15 were parties to the Montreal amendment (1997), but only three were parties to the Beijing amendment (1999) (UNEP, 2003). According to the Montreal Protocol, these countries should have frozen their CFC consumption and production at the 1995-1997 levels by 1st July 1999 (UNEP, 2002b).

Greenhouse gases and climate change

To achieve this, licensing systems have been implemented to control imports and exports of these substances. Government institutions have made different contributions to these efforts – establishing and bringing into force needed regulations ,and various civil society and private sector bodies have joined forces. To support national efforts to comply with the convention or the protocol, an OzoneAction programme is being developed with the Multilateral Fund for the Implemen-

Another global atmospheric issue of regional concern is climate change, made worse by the concentration of the so-called greenhouse gases. According to the Intergovernmental Panel on Climate Change, three gases – carbon dioxide, methane and nitrous oxide are responsible, respectively, for approximately 60, 20 and six per cent of global warming (or the greenhouse effect) originating in human activities (McCarthy and others, 2001). Although these gases exist naturally in

the atmosphere, the rapid release of additional amounts results from human activities such as burning fossil fuels, deforestation and agriculture. Global estimates based on apparent net fossil fuel consumption indicate that during the period 1970-2000 there was an increase in total carbon dioxide emissions until 1974, owing to the doubling of per capita emissions between 1950 and 1973. These emissions were stabilised after 1974 – until the present—basically because of high petroleum prices (Marland and Boden, 2000c). In 1992, about 84 per cent of global carbon dioxide emissions came from industrial processes and 16 per cent from land use changes (WRI and others, 1998). In the mid-1990s, preliminary estimates indicated that the Latin America and Caribbean region was responsible for approximately 11 per cent of global carbon dioxide emissions, with 4.3 per cent of emissions coming from industry and 48.3 per cent from land use changes. Regional methane emissions from anthropogenic sources (mainly livestock farming and the production and consumption of fossil fuels) represented 9.3 per cent of the world total (WRI and others, 1996). Average per capita carbon dioxide emissions in the region were 2.7 tonnes in 1998, very much below the 10.2 tonnes calculated for high-income economies (19.4 tonnes in North America, 7.5 tonnes in Europe and Central Asia and 7.4 tonnes in Western Asia) and also lower than the world average of 3.9 tonnes (UNEP, 2002d). These estimates indicate that Mexico and Brazil are among the 20 main carbon dioxide-emitting countries in the world, in order of magnitude, while Venezuela, Argentina, Colombia and Chile are among the top 60

emitting countries (Marland and Boden, 2000a). As to per capita emissions, several nations and territories in the Caribbean (the US Virgin Islands, the Netherlands Antilles, Aruba, Trinidad and Tobago, the Cayman Islands and Bermuda), as well as Venezuela, all oil producers, are among the 60 main emitting countries (Marland and Boden, 2000b). Due to the relatively small population in the Caribbean, this per capita contribution is not a significant percentage of the total volume. The supply and consumption of fossil fuels account for almost 80 per cent of global carbon dioxide emissions, 20 per cent of methane and a significant amount of nitrous oxide (UNFCCC, 2001). Other carbon dioxide sources are land use change (deforestation) and the forestry sector and, to a lesser degree (around three per cent), cement production. Other methane sources, on the other hand, are livestock (30 per cent of emissions), wetland rice farming (20-25 per cent) and garbage disposal. Agriculture increases emissions of anthropogenic nitrous oxide, mainly through the use of fertilisers. Deforestation is considered to be the main source of atmospheric emissions in Latin America and the Caribbean, particularly due to the impact in the Amazon basin; however, official estimates for Brazil, where they would be most useful, are still not available (UNEP, 1999c; COPPE, 2002). Large cities in the region, as well as many medium-sized cities, also emit greenhouse gases, mainly generated by motor transport and industrial production. Although carbon dioxide is generally the main greenhouse gas, if total greenhouse gases are estimated in carbon dioxide equivalent units, methane is more important in countries such as Argentina, Chile and Uruguay (UNFCCC and SBI, 2000). More than 71 per cent of methane emissions in South America and 48 per cent in Mexico come from livestock.

The global effort against climate change Parallel to the international movement against ozone depletion, the first international conference on the world climate was held in 1979 and ended by calling on governments to predict and prevent potential climate changes caused by human activity that could adversely affect humanity. The Intergovernmental Panel on Climate Change, coordinated by UNEP and the World Meteorological Organization, was established in 1988. In 1990 the panel confirmed the existence of a global warming process influenced by human activities and consequently required international decisions regarding mitigation and adaptation. The General Assembly of the United Nations responded to the appeal and, that same year, initiated negotiations that resulted in the adoption, in May 1992, of the United Nations Framework Convention on Climate Change. In the context of the convention, the Kyoto Protocol was adopted in 1997, proposing a binding commitment for developed countries to reduce their greenhouse gas emissions to at least five per cent less than their 1990 levels during the period 20082012. The protocol's specific details were defined at ensuing meetings of the convention's conference of the parties, and its entry into force is subject to ratification by 55 parties, including those responsible for at least 55 per cent of total carbon dioxide emissions in 1990. In 2002, various parties to the convention (whose combined emissions would allow for the protocol to enter into force), including the European Union, Japan, Canada and New Zealand, had signed the protocol. Other major signatories such as Australia and the Russian Federation had still not done so, however (UNFCCC, 2003). The United States, which accounts for a major share of global emissions, has not signed, although it ratified the convention in 1992. According to the Kyoto Protocol, reducing greenhouse gas emissions to the agreed levels will require important measures to be taken in fields such as improved energy efficiency, reforms in the energy and transport sectors, promotion of renewable energy sources, elimination of inappropriate fiscal measures and market failures, improved waste management, agriculture and livestock-rearing technologies, and protection of forests and other carbon sinks. · In addition to direct national policy options that are the obligation and responsibility of all the developed countries participating in the convention and the protocol, three international cooperation mechanisms have been proposed to boost changes: · clean development initiatives to reduce emissions in developing countries, which would result in emission credits for participating developed countries; · joint measures among developed countries to reduce emissions; and · the transfer of emission reduction units, so that countries with mitigation advantages could trade results with other interested countries. The international debate on the protocol revolves around the rules for implementing these mechanisms, as well as the degree to which they may be considered supplementary to direct national emission reduction measures and, finally, procedures to enforce compliance with the commitments assumed by the parties.

In any case, emission estimates are only approximate because it is difficult to obtain reliable data from most countries in the region (UNEP 1999a, UNFCCC and SBI 2000). Identification of specific emission factors for particular systems or regions is still preliminary and the characteristics of the forestry situation and changes in land use are hard to define. In general, few data are available, and information has to come from diverse statistics and even anecdotal evidence. Furthermore, there is a widespread lack of monitoring infrastructure, except in some large metropolitan areas. In many countries carbon emissions could be greatly reduced, by taking advantage of renewable biomass energy sources and establishing carbon sinks by means of forest conservation programmes and reforestation. For example, the use of ethanol as a substitute for petrol could reduce carbon dioxide emissions (see the section on Socio-economic trends). The Latin American and

·

Caribbean Initiative for Sustainable Development adopted by countries in the region at the World Summit on Sustainable Development (Johannesburg, 2002) has set the goal of increasing renewable energy use to 10 per cent of total energy consumption before 2010 (UNEP/ ROLAC, 2002). According to the scenarios developed by the Intergovernmental Panel on Climate Change (IPCC) on the process of global warming, the global average surface temperature will increase by between 1.4 and 5.8 degrees Celsius by 2100 relative to 1990, and it is projected that the average sea level will rise by between 0.09 and 0.88 metres by the same date (IPCC, 2001; McCarthy and others, 2001). The projected rate of warming is much greater than the changes during the 20th century and is very likely to be have been unprecedented during at least the last 10,000 years. It is also thought very likely that almost all land areas will warm more

Latin America and the Caribbean

National climate change inventories In February 2003, 27 countries in the region had submitted official national communications to the Secretariat of the Framework Convention on Climate Change (UNFCCC, 2002b). Others (including Brazil and Venezuela) have only published preliminary reports (CETESB, 2002; COPPE, 2002; EMBRAPA, 2002a, 2002b; Perdomo and others, 1995). At the end of 2002, the secretariat included a database on these inventories on its website, to which the public has access. However, it is important to keep in mind that the possibility of comparing existing reports is hindered by differences in methodology and data presentation; furthermore, few reports include historical series, which makes it difficult to determine national or regional trends. Argentina In Argentina, net carbon dioxide emissions were 66.7 million metric tons in 1990 and 84.9 million metric tons in 1994 (UNFCCC, 2000a). In both years, fossil fuel combustion accounts for approximately 89 per cent of total emissions, excluding change in land use and forestry, a sector that serves as a net carbon sink in Argentina. Methane emissions were estimated at 3.6 million metric tons in 1990 and 4.2 million metric tons in 1994, generated basically by livestock raising (74.5 per cent and 68.4 per cent, respectively, for those years). Brazil According to a preliminary greenhouse gas inventory, Brazil had carbon dioxide emissions from fossil fuels and biomass burning equivalent to 107.3 million metric tons in 1990 and 117.1 million metric tons in 1994 (COPPE, 2002). In 1994, gross carbon dioxide emissions from biomass burning in the land use change and forestry sector (LUCF) were 81 per cent of the combined emissions from the energy and industrial sectors (no information is available for carbon dioxide capture from land use change and forestry); the corresponding average for Latin America and the Caribbean was 28 per cent (UNFCCC, 2002b). Between 1990 and 1994, carbon dioxide emissions from fossil fuels increased at a faster rate than the total gross domestic energy supply between 1990 and 1994, indicating a greater use of carbon-intensive fuels in the Brazilian energy system. This occurred at the expense of renewable biomass sources, which dropped from 24.8 to 22.3 per cent of the gross domestic energy supply (COPPE, 2002). Methane emissions in 1990 were estimated at 10.1 million metric tons, originating basically in livestock (90 per cent) and waste treatment and disposal (7 per cent) (EMBRAPA, 2002a, 2002b; CETESB, 2002). Mexico Mexico appears to be the region's main carbon dioxide emitter: 444.5 million metric tons in 1990 (INE, SEMARNAP, 1997). In 1990, the single largest source of emissions was land use change and forestry, with 30.6 per cent of emissions; followed by processing and energy industries, with 24.4 per cent; transport, with 21.3 per cent; and other industries (particularly cement and metallurgy), with 14.6 per cent. Fossil fuel combustion was responsible for 67 per cent of emissions. Methane emissions are estimated at 3.6 million metric tons for 1990, mostly from livestock raising (48 per cent) and fugitive fuel emissions (28.5 per cent). The country's second national communication to the United Nations Framework Convention on Climate Change indicates that total carbon dioxide emissions (excluding land use change and forestry, which are only reported for one year) grew by 73 per cent in the 1990-1996 period, although they decreased in 1997 to only 33 per cent of the 1990 level (INE, SEMARNAT, 2001). In 1996, total emissions from greenhouse gases (in carbon dioxide equivalent terms) were 75 per cent carbon dioxide, 23 per cent methane and 2 per cent nitrous oxide. Venezuela A preliminary greenhouse gas inventory estimates that Venezuela generated 190.8 million metric tons of carbon dioxide in 1990 (Perdomo and others, 1995). The energy sector (mainly fossil fuel combustion) accounted for 56 per cent of emissions and deforestation for 44 per cent (basically in Venezuelan Amazon, which covers 60 per cent of the national territory). Carbon fixation through forest management was estimated to be equivalent to three per cent of the total emissions for that year. Methane emissions were estimated at 3.2 million metric tons, originating basically in the energy and agricultural sectors (58 and 30 per cent, respectively).

rapidly than the global average, particularly those at northern high latitudes during the cold season. Present models indicate that rising global temperatures may affect climate conditions such as rainfall, wind speed and frequency of extreme climatic events (storms, torrential rains, hurricanes and drought). There are also potential impacts on human disease and death rates related to climate change. Increased temperatures may cause more tension from heat, as well as the spread of tropical diseases by vector insects on higher land and an increased incidence of diseases such as malaria, schistosomiasis, dengue fever, yellow fever and cholera (IPCC, 2001; McCarthy and others, 2001).

cern, several questions must be tackled from a regional point of view, including:

On a regional scale, climate change would also affect ecosystems, water resources, agriculture and coastal systems in Latin America and the Caribbean (IPCC, 1997). Ecosystems such as forests and grasslands, mountain systems and transition zones are particularly vulnerable. An exceptionally serious problem would be the continued deforestation in the Amazon, which would have a significant impact on the global carbon cycle. Changes in the water cycle would especially endanger arid and semi-arid zones, as well as hydroelectric energy generation, cereal and livestock production in places such as Costa Rica, Panama, the lower slopes of the Andes ,Chile and Argentina. A change in precipitation pattern would have an adverse effect on crop production in the region. Coastal systems in many countries in the region could shrink and lose biodiversity, with damage to the infrastructure and salinisation problems. About 60 per cent of the regional population live less than 100 kilometres from the coast (Cohen and others, 1997), and many of the region’s large metropolitan areas are highly vulnerable to a rise in sea level including, obviously, the main ports and coastal cities. The small island states in the Caribbean are in the greatest danger, even though they contribute very little to regional greenhouse gas emissions, and much less to global emissions. (See the section on Coastal and marine areas.) Among the indicators of global climate change is the increased frequency, persistence and intensity of the ancient cyclical phenomenon known as El Niño Southern Oscillation. El Niño begins when the surface waters in the eastern Pacific Ocean close to the Equator start to warm up, alternating with cooling of the same waters (known as La Niña) every three or four years. During El Niño years, there are severe droughts or unusually heavy rainfall, as well as a loss of fishery resources, causing socio-economic losses in many countries in the region (see the section on Coastal and marine areas).

Regional response Climate change is a threat to Latin America and the Caribbean because of the vulnerability of the environment (both natural and urban) and the region’s high poverty levels. Although this change is a global con-

·

The magnitude and rate of climate change in different parts of the region;

·

The relative vulnerability of ecological and socio-economic systems to climate change and its impact on them;

·

The identification and implementation of feasible response options and the capacity of the region to promote better options; and

·

The effective role of countries in the region in promoting regional and international measures.

The environment takes a long time to adapt to climate change, so there is an urgent need to take measures now. Even if concentrations of greenhouse gases stabilise at their present levels, something of their predicted impact will persist for hundreds of years .(IPCC, 2001; McCarthy and others, 2001). The regional response to climate change basically falls within the framework of the principles and guidelines accepted by the 33 nations of Latin America and the Caribbean which, by September 2000, had ratified the Framework Convention on Climate Change (UNFCCC). Of these 33 nations, 24 had ratified the Kyoto Protocol by November 2002 (UNFCCC, 2002a). The main mitigation and adaptation activities proposed by the UNFCCC include measures aimed at the energy, transport and agriculture sectors, waste management and increased capacity of carbon sinks. The following table presents activities planned or ongoing in five of the countries of the region that have presented national communications to the UNFCCC Secretariat: Argentina, Chile, El Salvador, Mexico and Uruguay. Latin American and Caribbean countries maintain a variety of positions regarding the role that carbon sinks can or should play in implementing the Kyoto Protocol, and this needs to be taken into account. This was one of the points that caused most controversy at the five conferences of the parties held between 1998 and 2001, during the negotiations to define rules and operational details (IISD, 2000; 2001; Ott, 2002). Three groups of countries have expressed diverging positions on this matter. The so-called Umbrella Group (the United States, Canada, Australia, Japan, New Zealand, Norway, the Russian Federation and Ukraine) urged that activities that capture carbon from the atmosphere (such as forest conservation, reforestation and forestry plantations) be recognized as clean development mechanisms for joint implementation. The “Environmental Integrity Group” (Switzerland, Mexico and the Republic of Korea) maintains a similar position to

the umbrella group but with relatively less economic interest in the outcome, with support from Bolivia, Chile, Costa Rica, Colombia, Peru and Uruguay. Among those opposed to this approach and in favour of placing an absolute limit on the role of sinks as part of the implementation mechanisms are the European Union and different developing countries including Brazil and Jamaica. Their position is to include only projects that promote the reduction of emissions and not those that would capture emissions, present or future. At the seventh conference of the parties held in Marrakech, in November, 2001, it was agreed to accept the use of these and other mechanisms only as a supplement to each country’s actions to directly reduce emissions. Other measures convergent with the goals of the UNFCCC are improving the legal framework on matters related to conserving forests and reforestation, and establishing restrictions on air pollution. Mexico has taken measures in both respects, and many other countries in the region, such as Uruguay and several countries in Central America, have recently amended their forestry laws. In the Caribbean, only Aruba and Cuba has updated their legislation linked to UNFCCC issues, but more than 10 countries in the sub-region have established mechanisms to coordinate their activities to adapt to global climate change. Innovative economic instruments are also being promoted including – as in Costa Rica – trading transferable greenhouse gas mitigation certificates and imposing green taxes on petrol (UNEP, 2000). As to energy, several countries in the region are promoting energy efficiency and the use of alternative sources (wind, solar, hydroelectric, biomass and biogas) (UNEP, 2000). Experiments on wind energy are taking

125

place in Barbados, Costa Rica, Cuba, Curaçao and Jamaica, among others. Curaçao has been operating a three megawatt wind energy plant since 1993 and, in 1999, Barbados had more than 31,000 solar water heating units installed (MPE, 2001). Costa Rica, for its part, has just approved a project to trade transferable mitigation certificates with a public/private consortium in the Netherlands based on a 20-megawatt wind plant. Biomass is used as a source of energy in the sugarcane industry in countries such as Brazil, Costa Rica and Cuba. There is more promotion of the use of photovoltaic cells in the region. Cuba, for example, has brought photovoltaic solar electricity to more than 1,900 rural schools (from a total of almost 9,000) and 300 doctors’ offices throughout the country (EcoPortal. net.2003; Red Solar, 2003). These activities show the emergence of a predominantly preventive orientation in activities and policies designed to counteract the impact of air pollutant emissions. Concerning both greenhouse gases and substances that damage the ozone layer, the advance of these initiatives will require not only communication and cooperation among many parties (government agencies, private initiative, international organisations and citizens), but also technology exchange and the promotion of effective financial mechanisms.

Urban areas

L

atin America and the Caribbean is the most urban ised region in the developing world, with threequarters of its population living in cities (UNCHS, 2001). The very large numbers of city dwellers consume huge amounts of energy, water and food and cause very serious environmental effects, such as pollution. Between 1970 and 2000, the urban population grew from 158.6 million to almost 383 million and the level of urbanisation rose from 57.4 to 75.3 per cent. At the beginning of the 21st century 79.8 per cent of the population in South America (273.2 million), 67.3 per cent in Mesoamerica (92.2 million), and 63 per cent in the Caribbean (17.2 million) lived in urban areas, although there are great differences within each subregion (CELADE, 2002). In 1950 only 35.4 per cent of the Caribbean population lived in urban areas; in 1970, the urban population increased by 47.4 per cent and by 1995 it had reached 62.4 per cent (UNEP, 1999). Total population is projected at 654 million (CELADE, 2002) and it is expected that by 2020 the urban population in the region will reach 526 million or 80.4 per cent of the total. This level of urbanisation is due, to a great extent, to the unprecedented growth rate of some cities in Latin America and the Caribbean during the 20th century, both from the natural increase in urban population and

rural immigration. For example, Caracas grew by an average of 7.6 per cent each year during the 1940s and Bogota by an annual 7.2 per cent in the 1950s. The population of two of the world’s megacities, Mexico City and Sao Paulo, grew during the 1970s by 5.1 million and 4.0 million respectively (Gilbert, 1998). In almost all countries, however, growth was tempered by a lowering of the birth rate from 1.8 per cent (1990-1994) to 1.6 per cent (1997-1999). This trend – added to the population’s increasing longevity — is the region’s demographic bonus because of the relative increase in the group of people of working age and the reduction in the number of their dependents, making it possible to increase productivity per capita and regional production as a whole (CEPAL, 2000b). During the past 30 years, regional urbanisation has passed through three phases: concentration of the urban population in large cities and metropolitan areas; growth of the population in intermediate cities (from 50,000 to 1 million inhabitants), and a period of stability when there was a fall in the rates of urbanisation and rural migration (CEPAL, 2000a). Intermediate cities sharply increased their share of urban expansion and it was thought they had better potential for sustainable development than large cities; however, in the 1990s, several of them were showing some of the same problems (CEPAL, 2000a). One of the features of urbanisation in the region is the concentration of people in megacities. Five of the 30 most populated cities in the world are in Latin

America: Mexico City (18.1 million inhabitants), Sao Paulo (17.8 million), Buenos Aires (12.6 million), Rio de Janeiro (10.6 million) and Lima (7.4 million) (UNCHS, 2001). The region has 51 cities with more than a million inhabitants: 33 in South America (14 in Brazil), 13 in Mesoamerica and five in the Caribbean.

It should be noted that in the transition towards advanced urbanisation, more instability is evident in countries where the change is in full swing, where urban spread is more accelerated with more rural migration and, therefore, where there is rapidly growing demographic pressure on cities.

The result of the growth patterns described is that four groups of countries can now be classified according to their degree of urbanisation (CEPAL, 2000a).

It is also noteworthy that the concentration of population in the main cities is more in countries with a smaller total population, even though they may be in a demographic transition phase. Thus, more than 40 per cent of the urban populations of Chile, Costa Rica, Guatemala, El Salvador, Haiti, Panama, Paraguay, Peru, Dominican Republic and Uruguay are concentrated in the respective capital cities (CEPAL, 2000a).

●

Countries where as yet there is little urbanisation or that are still predominantly rural: Guatemala, Haiti and Honduras.

●

Countries where urban transition is moderate (50-70 per cent urbanisation) with a tendency for the rates to accelerate: Bolivia, Ecuador and Paraguay in South America; El Salvador, Nicaragua, Costa Rica and Panama in Mesoamerica; and the Dominican Republic in the Caribbean.

●

Countries becoming rapidly urbanised (70-80 per cent): Mexico in Mesoamerica; Cuba and Trinidad and Tobago in the Caribbean; Brazil, Colombia and Peru in South America.

●

Countries where urban transition has become consolidated or has advanced: Argentina, Chile, Uruguay and Venezuela in South America and the Bahamas, Barbados, and Jamaica in the Caribbean.

It is important to mention some of the more balanced land development experiences in countries like Cuba and Costa Rica, where access to services that were once only available in urban areas, such as electricity and telephones, has been extended to almost the whole national population. This development pattern may offset to a small degree for the environmental problems of large cities.

Socio-economic dynamics Urban poverty is probably one of the most serious problems facing Latin America and the Caribbean where

a majority of the population has still not benefited from the significant social and economic reforms of the past few years. Thus, a third of the population of Sao Paulo and 40 per cent of the population of Mexico City live below the poverty line. The region’s rate of urban poverty is the highest in the world, with 39 per cent of families below the poverty threshold. Although poverty is greater in rural zones (55 per cent as opposed to 39 per cent in urban areas), in absolute terms there are twice as many urban poor than rural poor (MacDonald and others, 1998). This was not always the case: at the beginning of the 1980s most of the poor lived in rural areas. At the end of that decade the concentration of poverty in urban areas reached the highest ever, even in countries where most people live in rural areas. Ten years later, at the end of the 1990s, six of every 10 poor people lived in cities, in contrast to Asia and Africa, where most of the poor are still in rural areas (CEPAL, 2000a). Over the past 30 years there has been a general tendency for the poor to congregate in urban areas.

some of which are described in the section on Disasters). The problems caused by poor housing are well known and include high environmental health risks (because of a lack of access to drinking water, drainage and sewage networks, as well as deficient solid waste management), limited access to transport, and overcrowding.

One of the most notable physical demonstrations of the region’s urban poverty is the growing deterioration of housing and access to basic public services. The poor have very limited access to housing and land and in 1990 the housing shortage was estimated to be 38 million units (40 per cent of all housing). There is a need for 17 million new housing units; 21 million units are dilapidated, with structural weaknesses, and are in dangerous zones with no proper services (Cira, 2002) (this danger has been highlighted by a number of tragedies,

In 1995, the region’s urban populations produce around 330,000 tonnes of solid waste every day. The three largest cities — Mexico City, Sao Paulo and Buenos Aires— produced close to a fifth of this total (PAHO, 1998; Acurio and others, 1997). The problem with solid waste is not only the amount produced but also its composition, which has changed from being mostly dense and organic to become voluminous and non-biodegradable (plastic, aluminium, hospital wastes, expired medicines, chemical compounds, electric batteries and others UNEP, 2002). For example, in Trinidad and Tobago the amount of organic waste dropped from 44 per cent in 1980 to 27 per cent in 1994, while plastic waste grew from four per cent to 20 per cent (UNEP, 2000).

Solid waste Solid waste management in Latin America and the Caribbean has evolved alongside urbanisation, economic growth and industrialisation. Although the waste problem has existed for many years, particularly in urban areas, up to now many countries and most intermediate and smaller cities in the region have not taken corrective measures, and it has become a problem of vital importance.

The volume of waste also causes concern: solid waste produced per capita has doubled over the past 30 years, from 0.2-0.5 to 0.5-1.2 kilograms (kg) per day, with a regional average of 0.92 kg (Acurio and others, 1997). In the capital or in most populated cities, 10 were above the regional average in daily waste production in kilogrammes per capita: Sao Paulo (1.35), Port of Spain (1.2), the Mexico City metropolitan area (1.2), Caracas (1.17), the Monterrey metropolitan area (1.07), Rio de Janeiro (1.0), Salvador de Bahia (1.0), Panama City (0.96), San José (0.96) and Cartagena (0.93). Furthermore, not all solid waste was collected in the most populated capitals and cities; the 10 cities with less waste collection were: the Lima metropolitan area (60 per cent), San Salvador (60 per cent), Santo Domingo (65 per cent), Managua (70 per cent), Tegucigalpa (75 per cent), the Mexico City metropolitan area (80 per cent), Asuncion (80 per cent), Guatemala City (80 per cent), the Monterrey metropolitan area (81 per cent) and Quito (85 per cent) (Acurio and others, 1997).

Almost 90 per cent of waste is collected in the region, although the percentage is higher in the cities of San Jose and Panama (Acurio and others, 1997).

Environment Outlook

Collection does not, however, guarantee proper disposal, and there are no mechanisms to dispose of 43 per cent of the waste collected (UNEP, 2002). It is calculated that Guatemala City, with more than 3.2 million inhabitants, collects 80 per cent of its 1,200 tonnes of daily waste, but it is all sent to open-air dumps. In San Salvador, the second most populated city in Central America, with 1.3 million inhabitants, only 60 per cent of the 700 tonnes of daily solid waste is properly disposed of. While some countries have a legal framework to control waste, almost all lack the physical Infrastructure and human resources to apply it.

Water quality The expansion of urbanised areas in many metropolitan zones exerts enormous pressure on water resources. On the one hand, an increased population means increased consumption; on the other, urbanisation makes the soil waterproof, particularly in aquifer recharge areas that supply those same populations. In spite of these pressures of demand and soil impermeability, the situation in Latin America and the

Caribbean is not as serious as in other parts of the world. By 2000, some 93 per cent of urban dwellings had improved water supply and 87 per cent had sanitation systems. These, however, are general values, since in most Latin American cities the amount and quality of water, its distribution and safety, are directly related to income (Pírez, 2000). For example, in the city of Puebla in Mexico, 10 per cent of the higher-income groups consume 300 litres per capita per day; the middle class (slightly fewer than half the city’s inhabitants), consumes 175 litres per capita; finally, and the poorest (42.9 per cent of the population) consume 158 litres per capita per day (Pírez, 2000). In Haiti, only 48.8 per cent of the urban population have access to drinking water and barely 26 per cent have sanitary services. Just as important as its supply is water’s proper after-use treatment, but less than five per cent of municipal sewage water is treated before being discharged (UNEP, 2000). The Rimac River is the main source of water supply for the city of Lima, Peru, yet over half (51 per cent) its microbiological pollution comes from the city itself; 83 per cent of dumped organic matter originates in the capital’s urban industry (CONAM, PNUMA, 2001). In Colombia it is estimated that every year some 4.5 million cubic metres of sewage are dumped, 90 per

Excessive groundwater withdrawals in the Valley Valley of Mexico At present, the Valley of Mexico aquifer supplies close to 70 per cent of the water consumed in the Valley of Mexico 3 Metropolitan Zone (VMMZ), at the rate of 45.4 m per second. However, the growth of this metropolis of more than 18 million inhabitants has caused the progressive overexploitation of underground aquifers (almost double their recharge capacity). In earlier decades aquifers to a depth of 100 metres were exploited; at present aquifers of poorer quality are exploited up to depths of more than 450 metres. Overexploitation of the aquifer has reduced the level of water where there is a concentration of wells, and has affected its quality. From 1983 —when systematic sampling was begun— a drop has been observed in the level of groundwater that varies between 0.1 and 1.5 m annually in the different areas of the VMMZ. Between 1986 and 1992, the net drop in the areas of greatest extraction was 6-10 metres. One of the most dramatic consequences of the drop in the water level has been ground subsidence, which has been a serious problem since the beginning of the 20th century. The city sinks at the rate of 5-40 centimetres annually, weakening the foundations of buildings and making them more vulnerable to earthquakes, with a high risk for the population. The maximum accumulated subsidence in the central region at the end of the 20th century reached 10 m, at a rate of 48 centimetres annually. Subsidence has caused extensive damage to infrastructure, including the foundations of buildings and the drainage system, resulting in water leakage from the distribution network calculated to be about 37 per cent of the supply. Losses from slanting land mean that some zones need constant pumping to drain sewage and rain water. As groundwater is exhausted, the need to bring in water from neighbouring basins increases; the resulting ecological and economic costs could make this unsustainable. The present rate of demographic growth in the VMMZ means 3 that the demand for water will increase by 7.2 m per second in the next 10 years. If remedial measures are not taken, 3 by 2020 the water deficit will be 21 m per second (46 per cent of present consumption); the only solution will be to bring in water from distant sources, or undertake a massive redistribution of population.

cent of which comes from household and industrial sources. Colombia and Mexico together generate twothirds of the total organic surface water load that empties into the north-east Pacific, for a total 92,767 tonnes of organic pollutants (PNUMA, 2001). In 1995, only 39 per cent of 140 small Caribbean industries treated their sewage in any way. Approximately 64 per cent of sewage water is discharged in marine and coastal zones, 25 per cent into the soil, six per cent into drains and four per cent on to crops as irrigation (UNEP, 1999). In most countries in Latin America and the Caribbean consider water resources management of prime importance, apart from its treatment before and after use. In spite of progress in recent years, in general wa-

ter quality problems persist because of poor operation and maintenance services. Public management difficulties in maintaining the present system and investing in its expansion – especially in the poorest and most recently urbanised areas – began in the 1980s, and have resulted in decentralising services and more private sector participation (Pírez, 2000; CEPAL, 1998). This has brought about a debate on how to set tariffs to allow maintenance costs to be covered, as well as paying for the replacement of the necessary infrastructure. However, to date no management model has been devised that would ensure environmental equity and sustainability (see experiences on payment for water resources’ environmental services in Chapter Three) (Idelovitch and Klasringer, 1995; Pírez, 2000). Finally, pollution of surface and groundwater has intensified, leading to greater discussions and conflict regarding of

water in urban areas (PAHO, 1998; CEPAL, 1994; Dourojeanni and Jouravlev, 1999).

Air quality Urban air quality in the region has noticeably worsened over the last 30 years. Today, air pollution has a permanent effect on the health of more than 80 million inhabitants, each year causing some 2.3 million cases of chronic breathing problems in children, about 100,000 cases of chronic bronchitis in adults and causing close to 65 million days of work to be lost (CEPAL, 2000a - detailed statistics on diseases and countries appear in the section on Environment and Human Health). Factors that have contributed to the deterioration of the atmosphere in large urban conglomerates include the number and age of vehicles, traffic congestion that increases travel time, industrial activity and the inefficient use of energy. Other important causes include the quantity and quality of fuels and poor control of emissions from vehicles (CEPAL, 2000a; ECLAC and UNEP, 2001). Other contributory factors are forest fires, and the use of household fuel. The use of motor vehicles causes most pollution in cities, and explains between 80 and 90 per cent of lead in the air, even though unleaded gasoline has been available in most countries in the region for some time (World Bank, 2001). In addition, more private cars, poor public transport and a lack of planning (leading to even more traffic congestion), increase emissions from moving vehicles and thus air pollution (CEPAL, 2000a). In the 1990s, there was a 6.2 per cent increase in emissions of suspended particles and, depending on their composition, increases of between 22 and 45 per cent in polluting gases (ECLAC and UNEP, 2001 - see the section on Atmosphere).

free land far from emergency services. Existing land use control mechanisms have not been able to halt these precarious settlements, many of which, especially to begin with, have no resistance to natural threats-, often not even basic low-cost mitigation measures such as retention walls and enough surface drainage (BID, 2000). On the other hand, it is important to note that it is not always the worst events that cause most damage to the population. Their impact also depends on the quality of constructions, whether cities and other infrastructures are well-designed and whether there is a good early warning system in place, as well as measures to deal with emergency and their subsequent salvage and reconstruction operations. It has been shown that the investment needed for these three preventive measures (quality, design and organisation) is less than the cost of rebuilding and can be used with more effect (CEPAL, 2000a).

Built environment Matters of relevance to the built environment, a feature of the urban ecosystem, include: Urban infrastructure and services among which: ·

Transport services are of particular interest because of their environmental impact.

·

Environmental quality expressed in the state of conservation of the urban landscape, especially in green zones.

·

Cultural, architectural and historic heritage, especially buildings of particular value.

Transport systems

The vulnerability of human settlements in Latin America and the Caribbean has deep historical and social roots. Many of the region’s principal Pacific coast cities were founded on highly seismic territories or, like those in the Mesoamerican Caribbean, in the path of hurricanes (see section on Disasters). To this is added the growth of cities on unstable land, with steep inclinations or in zones subject to flooding from rivers, as a consequence of demographic pressure and, in particular, rural migrations.

Since the 1990s, the increase in traffic and the demand for transport has intensified the problems of congestion, delays, road accidents and environmental problems, particularly in large cities. All this also represents a high economic cost: at present, the deployment of urban transport accounts for about 3.5 per cent of the regional gross domestic product, added to the cost of travelling time which, it is estimated, accounts for another three per cent of the GDP. As cities are growing and travelling time increasing, it is probable that these percentages will continue to rise (CEPAL, 2000a).

Urban growth in vulnerable zones is combined with the increasing urbanisation of poverty (see above), creating new vulnerabilities. The poorest populations tend to settle in zones more exposed to hydro-meteorological natural threats, such as floods, erosion and landslides. Furthermore, they generally occupy low-cost or

Although public vehicles are still the most used form of travel in urban zones, the growing number of private vehicles – directly related to higher middle class incomes – has become a serious problem (CEPAL, 2000a). Liberalising vehicle imports and deregulating collective transport has had severe effects in cities like Lima and San-

Restoring Havana's Havana's historic centre The historic centre of the city of Havana covers an area of 2.1 km2, with 3,744 buildings of historic and architectural importance. About 750 of the monuments are considered to conserve the character of Cuban architecture and culture, which is a blend of various European cultures. Cuba began to finance the rehabilitation of the Havana's historic centre in 1981, and in 1982 UNESCO declared it, and its system of fortifications, to be a Cultural Heritage of Humanity. To meet the rehabilitation objectives, in 1993 the Council of State declared the historic centre a Priority Conservation Zone, giving the Historian's Office authority to develop a self-financed management system and to streamline rehabilitation work.

tiago. In Santiago, only 16,000 collective transport vehicles serve 4.3 million inhabitants; in Sao Paulo, while the population grew by 3.4 per cent between 1990 and 1996, the number of motor cars increased ten-fold, by 36.5 per cent (Thomson and Bull, 2000; CEPAL, 2000a). To lessen congestion, some cities in the region have opted to improve road Infrastructure, widen streets and designate some exclusively for public transport and change the direction of traffic according to the time of day. Mexico City, Bogota, Santiago and Sao Paulo also impose restrictions on the use of vehicles.

Green areas All cities, but especially those in expansion, require development and maintenance of green areas for recreation and to capture carbon dioxide, a pollutant whose emissions are growing in cities without efficient motor vehicle regulations. For example, in the city of Lima there are 14.0 million square metres (m2) of green area (0.5 per cent of the urban territory), with a density of 1.98 m2 of green area per capita (CONAM and PNUMA, 2001). Santiago, Chile, has 46.0 million m2 of green area — 9.8 m2 per person — of which more than half are privately owned (UCH and others, 2000). Because cities are growing so rapidly, however, these areas are insufficient. In addition, the high price of residential or commercial building land makes it more difficult to expand green areas, especially when there is little land available. Municipal regulations, therefore, are often required to give citizens right of access to these areas.

Historic centres Policy discussions now have the region’s historic urban centres at their heart, spurred on by their growing deterioration as a result of social, economic and natural activities. Examples of the rescue of important regional historic and architectural heritage include the city of Havana (Cuba), Potosi (Bolivia) and Panama City. In San Salvador, the Historic Centre rescue plan has combined public initiatives with private sector support (from associations and universities among others) to revitalise the city’s old quarter (Barba and Córdoba, 2001).

·

Socio-environmental impact of regional urbanisation Regional development over the past 30 years has caused growing urbanisation that has negative effects on the quality of city life, particularly with regard to the environment. Until the 1970s, the post-Second World War economic boom brought a gradual improvement in diverse infrastructure deficiencies, in spite of the marginalisation of much of the population concentrated in large cities with great limitations to the supply of basic and public health services. However, this generally positive evolution was halted by the economic crises of the so-called lost decade of the 1980s. Subsequent structural transformation of the region’s economies accentuated various environmental problems caused by liberalisation of transport and the property market, a weakening of industrial pollution control mechanisms and, in general, the emergence of an informal production sector. Social impacts included a general increase in urban insecurity, and old buildings were abandoned in the older cities. The largely horizontal expansion of cities over the past 30 years has left a growing ecological footprint on their natural surroundings. This includes the importation of environmental goods and services such as surface and groundwater, fossil minerals, and stone and sand for construction and to fertilise the soil. Powerful environmental degradation processes, such as deforestation, erosion and water, soil and air pollution, have also been put in motion. In coastal zones, unplanned urbanisation – often with tourism in view – accentuates the environmental impact on both land and sea. This causes solid waste disposal and drinking water supply problems, and leads to excessive extraction of groundwater, resulting in saline intrusion. In more than a quarter of the Caribbean territory, the islands’ population density is over 200 inhabitants per km2 and in some — like Barbados where,

Chapter 2: State of the Environment in Latin America and the Caribbean, 1972-2002

Environment Outlook

in 2002, the population density was 626.5 per km2 — it may be compared to that in large cities (CELADE 2002). Tourism is very important to these islands, and pollution of coastal and marine waters causes an immediate economic impact and raises urgent policy challenges.

Policies on basic human settlements problems Since the 1980s, regional urban policies (like public policies in general) have become more selective, although there has been more emphasis on their desired multidimensional features. The importance of private sector and civil society participation has also been highlighted, by means of a more decentralised policy approach. This approach proved its usefulness when solutions to environmental problems were combined with socially and politically effective employment programmes (CEPAL, 2000a).

Air quality administration is an example of focused management – it has made significant progress in several cities over the past 10 years. Cities with atmospheric monitoring have introduced new technologes not only to measure air quality, but also to improve their capacity to prevent episodes from becoming critical. The greatest improvements have been seen in the three cities with the most pollution problems: Mexico City, Santiago and Sao Paulo, , where they standards similar to those proposed by the World Health Organisation have been established (except for coal and sulphur dioxide, for which the standards in Latin American cities are less rigorous) (CEPAL, 2000a). Air pollution control efforts have unfortunately not been uniform throughout the region. A recent assessment indicates that only about a third of the countries have established national outdoor air quality standards or maximum limits for emissions from fixed or mobile sources (OPS, CEPIS, 2000; see section on Atmosphere).

Santiago, Chile: Metropolitan Region Pollution Prevention and Decontamination Plan In 1996 the Metropolitan Region of Santiago was declared a zone saturated by four atmospheric pollutants and a latent zone because of the high levels of nitrogen dioxide in the air. Since then projects have been undertaken to improve its air quality, although they have not succeeded in totally controlling the problem. Transport continues to be the most polluting sector in the region; it emits 48 per cent of breathable particles, 84 per cent of nitrogen oxides and 91 per cent of carbon monoxide. To this must be added significant emissions of volatile organic compounds (30 per cent) and sulphur oxide (34 per cent). Buses account for 21 per cent of the capital's pollution, trucks 13 per cent and light vehicles 14 per cent. Fixed sources produce 12 per cent, industries 14 per cent and residences 7 per cent. In 2000 the Santiago city government initiated the Metropolitan Region Pollution Prevention and Decontamination Plan (the first in the country) planned to be in place for 14 years, with assessments in 2000 and 2005. Its goal is that, by 2005, transport emissions of particle material will be reduced by 75 per cent and nitrogen oxides by 40 per cent. The plan contemplates the total removal of buses with unacceptable emissions indexes, and their replacement by vehicles using the cleanest technology (natural or liquid gas, hybrid vehicles, electric or others); beginning in 2004, devices to control emissions by diesel buses will be introduced. From 2003 a progressive improvement has been sought in the composition of gasoline. Technical conditions will also be established for the use of firewood as a domestic fuel, designed to reduce its present six per cent share of the capital's pollution. In the industrial sector, the plan will set standards for the emission of gases that produce polluting particles, specifically carbon monoxide and various sulphur, as well as a system that demands compensation payments for the 150 per cent of the emission produced by new industries, as a disincentive. Limits will be placed on particle emissions from industrial processes (to date this mechanism has only been applied to furnaces), and other limits on emissions of nitrogen oxides in furnaces and industrial processes. With this measure, the industrial sector should be able to reduce its emissions of nitrogen oxides by 33 per cent, bearing in mind that in recent years this sector had already reduced its particle emissions by 66 per cent.

Latin America and the Caribbean

An example of the integrated approach to managing urban environmental problems is found in Mexico where the General Law on Ecological Balance and Environmental Protection is part of an environmental policy based on sustainable development. Within the framework of this general law, in January 2000 the Environmental Law for the Federal District was promulgated to conserve and restore the metropolitan area’s ecological balance. Its objectives include: ·

the definition of principles to formulate, conduct and assess the Federal District’s environmental policy;

·

the definition of instruments and procedures to apply it;

·

the prevention of damage to the environment (such as air, water and soil pollution), and

·

the regulation of responsibility for such pollution.

Although the 1990s was a decade marked by persistent environmental problems typical of poverty and major cities, it also brought positive changes, such as more citizen participation, the development of public and private networks of bodies to protect the environment, the establishment of environmental education programmes and the beginning of efforts to reduce air and water pollution. These changes contradicted the doomladen projections of the 1970s about the process of regional urbanisation (CEPAL, 1995; Villa and Rodríguez, 1994; CEPAL, 2000a). However, a review of progress and the challenges faced to date shows the need to make important advances away from the present sectoral and fragmented urban habitat management and towards integrated and multisectoral strategies. In many cases housing policies been able to correct deficiencies in the provision of basic public services to informal settlements, but they have also contributed to the horizontal expansion of urban zones (ECLAC and

Limits to urban spread: the case of Mexico City Historically, the development of Mexico City has lacked a vision to integrate agriculture, urban expansion and conservation, and restore natural resources, with resulting competition between these activities and their deterioration. This becomes particularly relevant if we consider that, of the almost 146,000 hectares (ha) covered by the Federal District, 88,642 ha (59 per cent of the total) are an ecological conservation area, including 62,000 ha of communal property with a large indigenous population. This city green belt, which is shared with the states of Mexico and Morelos, provides a variety of environmental services: capture of carbon particles, climate regulation, aquifer recharge, preservation of wells, rivers and lakes and conservation of flora and fauna species, some of which are endemic. This conservation land is threatened by many factors, outstanding among which are: the pressure of property interests and the presence of 419 illegal settlements and 179 accepted settlements that occupy 3,134 ha (11 per cent of the area); the growth of rural settlements; a continuing agrarian crisis that erupted in 1994; fragmentation of parcels (20,000 parcels on 28,000 ha, according to the Federal District Ecological Regulation Programme); and the poverty of the inhabitants. It is proposed to build housing and commercial establishments in the central city area that has infrastructure and services (the so-called City Centre), while restricting these types of constructions in ecological conservation areas in surrounding and rural zones. This presupposes conditions for repopulating central areas and making better use of space with buildings of several floors for high domestic occupation and for other urban activities. This would allow the Federal District to absorb its population increase over the next 20 years, without the need to occupy new surrounding areas. As to green zones, it is suggested they be considered a system in themselves by designing a plan for their growth and care. A management plan would give everyone access to green zones for recreation and other important environmental services. The plan has clearly defined the rules for the city's future growth. An attempt will be made to persuade all concerned of the advisability of directing growth towards the city centre. No permits are issued to build housing units in the south or the east; on the other hand, procedures have been simplified in the central zone. This protects the ecological reserve zone where the aquifers are recharged and oxygen is produced for the city. In addition, decisive action is taken against invasions into the ecological reserves both in areas of extreme poverty and in the city's wealthiest sections. Source: GDF, 2000b, 2002.

UNEP, 2001). The lack of regulations on negative outside land market influences, and the failure to develop urban transport policies, have also encouraged dispersion and exclusion trends in large metropolitan zones and intermediate cities. The emergence of public agencies has been very significant over the last 10 years. Their aim is to adopt a conurbation approach to environmental problems. Other initiatives seek to deal with the land market problem by creating land banks or imposing an urban land added value tax. New transport experiments are under way, such as the use of trolleybuses in Quito, and the prohibition of private transport in Bogota by 2015.

139

This new integrated approach needs always to take into account the urban environment and the demands of social and economic sustainability as interrelated components in the management of human settlements. Urban land regulation, and the elimination of harmful subsidies, are essential components of this new vision, as is the reduction of the vulnerability to extreme climate phenomena that still exists.

Disasters

A

disaster is an event or a series of events that dis rupts the functioning of society or ecosystems and causes losses – to people and the natural or manmade environment – on such a scale that those affected are unable to cope, using their own resources (Coburn and others, 1994; CEPAL, 2002b). Disasters are classified according to their causes (natural or of human origin) and speed of impact (sudden or delayed - Coburn and others, 1994; CRED-OFDA, 2003). Direct human causes of disasters include wars and civil disorder, industrial disturbances (explosions or toxic spills) and traffic accidents (land, air or sea); these disturbances or accidents are known as technological disasters. Natural disasters can be geological, tectonic, hydrological, meteorological or biological: earthquakes, tidal waves, volcanoes, droughts, fires, hurricanes and tropical storms, tornados, floods and landslides, and epidemics. Disasters are generally seen as sudden events. However, often an accumulation of relatively minor occurrences creates a growing risk or threat. It becomes probable that when a disaster does happen it will have a determined impact. Besides threats and risks, a disaster is defined by the degree to which the affected territory, population and infrastructure are vulnerable. The often small but progressive accumulation of social and environmental damage heightens the risk to people and nature and makes them more vulnerable (Velásquez and Rosales, 1999). Losses are caused because people and objects are exposed (Munich Re Group, 2002). It is also clear that human activity - such as high population growth and density, unplanned changes in land use, environmental degradation and perhaps global climate change - worsen the impact of subsequent events– even natural ones. A disaster, therefore, occurs in vulnerable conditions as a consequence of a threat or a combination of threats.

Natural disasters in Latin America and the Caribbean The Latin America and Caribbean region is only too well aware of the devastation caused by natural disasters. From 1970-2001 they killed 246,569 people and affected another 144.9 million, causing economic losses of US$68,600 million (CRED-OFDA, 2003). Tectonic

activity (earthquakes, tidal waves, and volcanoes), and climate events (hurricanes, floods, avalanches and landslides, and fires), as well as epidemics, caused the most damage. As far as climate is concerned, two prime aggravating circumstances are the annual recurrence of hurricanes in Mesoamerica and the Caribbean, and the El Niño -Southern Oscillation (ENSO) that has an impact on the whole region. Geologically, the pressure of tectonic plates on the Pacific coast causes permanent seismic and volcanic activity throughout the subcontinent (UNEP/ROLAC, 2001; CEPAL, 2002b). It is estimated that, during the 1990s, disasters related to natural events caused 75,289 deaths, at an average annual rate of 7,529; however, in 2000-2001 this rate dropped to 2,634 (CRED-OFDA, 2003). In the Huracán Elena, 1995 last three decades of the 20th century, earthquakes were the main cause of death (47.2 per cent of the total), followed by floods (18.5 per cent), storms and hurricanes (14.0 per cent), volcanoes (9.3 per cent), © NASA, Goddard Space Center epidemics (6.2 per cent) and landslides (4.1 per cent). The most recent catastrophic events of this type include the 1997-1998 El Niño, Hurricane Mitch in Central America in 1998, the earthquake in Colombia and the landslides and floods in Venezuela in 1999, as well as the earthquakes in El Salvador in 2001. In the period 1990-2001 alone, the cost of the damage caused by these disasters was calculated at US$33,400 million. Although these figures are extraordinarily high, they probably underestimate the real impact because thousands of minor events in isolated places are not reported; in addition, the economic and social impact is very complicated, which makes it difficult to put a monetary value on the total cost to society and the environment (CRED-OFDA, 2003; BID, 2000; CEPAL, 2002b).

Tectonic and geological events During the past 30 years, tectonic and geological events have been the cause of most of the estimated 116,380 fatalities from natural disasters in Latin America and the Caribbean (CRED-OFDA, 2003). The pressure of tectonic plates is a permanent factor of seismic and volcanic activity all over the subcontinent (including the Caribbean basin), and in particular on the Pacific coast, where the pressure is between the oceanic and continental plates (Pacific and North American, Cocos and Caribbean, Nazca and South American) (UNEP/ROLAC, 2001; CEPAL, 2002b). The effect of this activity on the environment is to create a

10,000 lives, respectively (CRED-OFDA, 2003). The consequences of the Managua earthquake were tragically worsened by resulting fires in the city that caused another 73,000 deaths; in total, it affected 720,000 people and economic damage was put at US$845 million. More recently (1990-2001) there were major tectonic events in Bolivia, Colombia, El Salvador, Nicaragua and Peru. The most serious were in Colombia and El Salvador. The earthquake of January 1999 in Colombia took

During this time, the earthquake in Peru in 1970 caused the worst loss of life with 66,794 people killed, followed by earthquakes in Guatemala in 1976 and Managua (Nicaragua) in 1972 with losses of 23,000 and

Ecological and social implications of earthquakes in El Salvador The series of earthquakes that shook El Salvador at the beginning of 2001 began with one of 7.6 on the Richter scale, which was at first thought to be an isolated event. It was, however, part of a seismic cluster that lasted for several weeks. As poverty makes half the population of El Salvador very vulnerable, the very first of these events revealed complex social and ecological implications. Besides the loss of life and infrastructure caused by the series of earthquakes, there was a long-range impact on ecosystems and their populations. Artisanal fishermen lost an essential part of their berthing and fish processing infrastructure as well as the infrastructure to transport the fish to market. There was damage to 30,772 farms and, in order for farmers to save their crops, damaged irrigation systems had to be repaired before the rains returned three months later. The destruction of a fifth of the coffee processing plants led to mass unemployment and a serious drop in the incomes of thousands of rural families in a basically agricultural country that had suffered from Hurricane Fifi in 1974, the violent civil war from 1978-1992, the earthquake in 1986 and Hurricane Mitch in 1998. Source: UNICEF, 2001.

1,186 lives, left 8,563 people injured and affected another 745,000. The total economic impact was estimated at US$1,580 million (CRED-OFDA, 2003; CEPAL, 1999b). The earthquakes in El Salvador in January and February 2001 caused 1,159 fatalities and affected 1.6 million more people, with economic losses (both direct and indirect) of US$2,800 million (CRED-OFDA, 2003). In 1985, the Nevado de Ruiz volcano destroyed the Colombian the city of Armero situated at the mouth of a narrow canyon in the Lagunillas River deposition zone which drains an extensive area on the side of the volcano. The city was buried under lava flows and 22,800 of its 30,000 inhabitants were killed (CRED-OFDA, 2003; Kuroiwa, 2002). During the past decade, volcanic eruptions on Soufrière Hills (Montserrat, 1996), Popocatéptl (Mexico, 1997) and Galeras (Colombia, 1993) have caused most fatalities (32, 20 and 10, respectively) with Popocatéptl affecting the largest number of people, 75,000 in all (CRED-OFDA, 2003). In Nica-

ragua, the Cerro Negro volcano erupted three times in a decade (in 1992, 1995 and 1999), on the first occasion leaving two people dead and 300,000 affected (CRED-OFDA, 2003). The Pacaya volcano, in Guatemala, erupted four times during the 1990s, without fatalities but affecting 7,143 people.

Hydrometeorological events In the past three decades, hydrometeorological events (linked to precipitation and climate), including landslides, have been the second cause of loss of life in the region from natural disasters, killing 36.6 per cent of the victims. They also have a serious impact on productivity in the coastal and marine areas they hit. It is probable that the El Niño-Southern Oscillation was a significant factor in many of those events. In effect, there is evidence that ENSO is associated with an increased risk of disasters in several regions of the world,

The eruption of the Soufrière Hills volcano on the island of Montserrat The risk map produced after the eruption of the Soufrière Hills volcano on the island of Montserrat is a useful illustration of how the region responds to disasters. In July 1995 the volcano began to erupt with violent, and progressively worsening vapour explosions. Lava destroyed Plymouth, the capital, and the Montserrat airport, and the authorities had to evacuate more than half the population. It is estimated that it would be too risky to occupy the damaged 65 per cent of the southern part of the island (now the exclusion area) within the next 30 years. The new risk map for Montserrat lists the third of the island in the north as the only area where the risk probability makes urban development acceptable and, if respected, would make it possible to protect lives and property.

including Latin America and the Caribbean (IPCC, 2001). According to the Intergovernmental Panel on Climate Change, created by the United Nations Framework Convention on Climate Change, the frequency, persistence and intensity of ENSO has increased over the past 30 years as a consequence of global warming (IPCC, 2001; see section on Atmosphere). The impact of El Niño, in the form of drought and famine, was already recorded in Brazil back in 187778 and 1888 (WHO, 1999). During the first year of an El Niño event, starting in the month of July countries in South America (the Brazilian northeast, French, Guyana Suriname, Guyana and Venezuela) tend to experience abnormally dry conditions that last until March of the following year. There is also evidence of an increase in the number of people affected by landslides the year after El Niño begins, particularly in South America. In general, in this sub-region there is a link between El Niño and increased flooding. In the 1972-2002 period four ENSO events were recorded: 1972-1973, 1982-1983, 1986-1988 and 1997-1998 (OPS, 2000), and another such event is expected to begin in 2003-2004. The effect of the 19821983 El Niño was devastating and it later became more frequent, causing severe damage during the next two decades, until the 1997-1998 El Niño when the impact was even stronger. Both events were the worst experienced in the 20th century. The 1982-1983 El Niño led to a drop of 12 per cent in Peru’s gross domestic product, as well as a fall of 8.5 per cent in agricultural production and 40 per cent in fisheries production (CEPAL, 2000). The 1997-1998 El Niño unleashed catastrophic floods and caused severe

drought, with great economic losses in the northeast and south of Brazil, close to the Pacific coast of Ecuador, Peru and Chile, and in Paraguay, Uruguay and the northeast of Argentina (in some of these locations precipitation was 12-17 times higher than normal). In the northeast of Brazil, the recurrence of occasional drought and famine worsened between 1988 and 1998, although this was perhaps associated with a complex chain of economic, social and political factors. The ENSO phenomenon also brought severe drought to Colombia, Guyana and the highlands of Peru and Bolivia, as well as a dramatic drop in fishing on the Pacific coast (see section on Coastal and marine areas). Sea level rose 20 centimetres in the Colombian Pacific. The extensive forest fires that occurred in 1997 and 1998 in Mexico, Central America, Venezuela, Bolivia, Paraguay and Brazil were also associated with longer drought periods, possibly caused by El Niño (see the section on Forests) (Cochrane, 2002; WHO, 1999). This El Niño, which was the last in the 20th century, produced regional economic losses of approximately $15,480 million (CEPAL, BID, 2000). Apart from El Niño, other events associated with precipitation and climate have caused severe damage to countries in the region. In Mexico the floods of October 1999 caused 632 deaths, 530,000 people were affected and losses amounted to US$234 million (CREDOFDA, 2003). In Venezuela, the intense rains of December of the same year provoked an unprecedented national emergency, mainly affecting the state of Vargas and the north-eastern section of the city of Caracas. The floods also had a very severe impact on the northern coast. It is estimated that 30,000 people lost their lives, 366,547 were affected and the economic loss was US$2,000 million (CRED-OFDA, 2003).

Floods in the state of Vargas, Vargas, Venezuela, Venezuela, 1999 The strong rains that caused a disaster in the state of Vargas (Venezuela, 1999) were a predictable risk for which there had been no planning or preventive measures. With more than 30,000 deaths (the Venezuelan armed forces reported 50,000 deaths and 72,000 dwellings damaged), it was considered the most violent disaster of this type to occur in the 20th century. About 230,000 jobs were lost and there was serious environmental damage with massive coastal landslides causing great harm to vegetation and leaving large desert patches on mountainsides vulnerable to future floods. The fishery sector was also affected due to a fall in demand for fish, partly because the ocean fishing areas had been polluted following the floods. Landslides took residents by surprise, burying them beneath piles of rocks measuring up to 10 metres that were sent rolling down by the force of the steep slope. The disaster was caused not only by natural disturbances, but by decades of unplanned development in high risk zones, together with persistent deforestation that reduced the land's stability. Practically all towns located on ancient river deltas, as is the case in Venezuela, are vulnerable to similar catastrophes. Sources: DIGECAFA, 1999; CRE, 2000; CRED and OFDA, 2002.

In 2001, new floods had a dramatic impact in Argentina, Bolivia, Chile and Colombia, while drought led to economic and food emergencies in Central America, particularly serious in Nicaragua, El Salvador, Guatemala and Honduras. The drought in Central America that year directly affected 1.5 million people and had an economic impact estimated at US$189 million, including US$13.3 million spent on dealing with the food emergency and financing part of the year’s second crop (CRED-OFDA, 2003; CEPAL, 2002a). It is possible that the drought problems of 2001 were made worse by the new El Niño of 2002-2003. In Mesoamerica and the Caribbean, almost all countries are exposed to the hurricane belt that starts on the North African coasts, affecting both the Atlantic and Pacific slopes in these sub-regions. This makes them vulnerable to frequent damage caused by very intensive climate systems. In the small Caribbean island states, these events are so frequent and all-encompassing that they are one of the main causes of the sub-region’s environmental degradation. It is known that El Niño brings a reduction in hurricane activity in the Atlantic basin, the Caribbean and Central America (WHO, 1999). However, in 1998 hurricanes George and Mitch coincided with two unusual conditions: the tropical storm season began late and there was a rapid transition phase from El Niño to La Niña (the name given to the cold phase of the El Niño). Both hurricanes unleashed the greatest impacts of the

·

series, and cost several thousand lives and millions of dollars of material damage.

Epidemics Epidemics are an exceptional increase in the incidence of pre-existing infectious diseases in a territory or population (CRED-OFDA, 2003). In Latin America and the Caribbean, epidemics are the third cause of mortality from natural disasters, although the number of deaths is far below that from the other two causes mentioned above (6.2 per cent of the total number of victims in the period 1970-2001) (CRED-OFDA, 2003). Other natural disasters increase the risk of epidemics, as they cause affected populations to be displaced and lead to overcrowding — sometimes for very long periods — in delineated areas which then become more vulnerable to infectious disease transmission. The main epidemics recorded by the Pan-American Health Organization (PAHO) started with the human immunodeficiency virus, cholera, dengue fever, haemorrhagic dengue, leptospirosis, malaria, tuberculosis, Hantavirus pulmonary syndrome virus, bubonic plague, yellow fever and equine encephalitis (PAHO, 1998; see section on Environment and Human Health). The register of regional epidemics included in the CREDOFDA world database differs from the PAHO register and includes epidemics caused by arboviruses, diarrhoea, leptospirosis, malaria, measles, meningitis, bubonic plague and various respiratory diseases as well

Hurricane Mitch in Honduras The enormous losses caused by natural disasters put a sharp brake on the efforts of developing countries to improve living conditions. The case of Hurricane Mitch in Central America is notable both for its impact and the response to it. In Honduras, the country most affected, more than 7,000 people died and more than 12,000 were injured, and 618,000 people were moved to shelters or displaced. Economic and environmental damage is estimated at US$3,800 million. In Nicaragua there were 3,000 deaths and 65,000 people were directly affected, with economic and environmental damage estimated at US$988 million. The hurricane also caused loss of life and had a serious economic and environmental impact in El Salvador, Guatemala, the Dominican Republic and Costa Rica. In response to the disaster, Central American countries —with external assistance from North America and the European Union— were able to establish sub-regional governmental and non-governmental platforms to take mitigation and rehabilitation measures, and were given significant international financial and technical assistance commitments. It is also important to mention the impact of Hurricane Mitch on vegetation. The following pictures, based on satellite data, show the state of vegetation before and after the hurricane. The damage or stress suffered is shown in yellow and brown. Source: CEPAL, 1999a; USGS and CINDI, 1999.

as exanthematic typhus and other rickettsiosis (CREDOFDA, 2003). According to these data, 15,356 people died (and 1, 051,941 were affected) by these epidemics during the period 1970-2001: of these, 13,043 deaths were caused by diarrhoea (417,350 affected), 1,500 by meningitis (30,000 affected), 400 by measles (25 900 affected), 341 by various arboviruses (463,329 affected), 23 by leptospirosis (3,362 affected) and 12 by bubonic plague. Malaria showed a dramatic rise, from 12,000 people affected in 1998 to 100,000 in 2000, although there were no deaths (CRED-OFDA, 2003). Cholera was undoubtedly the principal biological disaster in the region with a total of 11,875 deaths and 1,199,804 cases registered from its sixth appearance in 1991 until July 1997 (PAHO, 1998). The epidemic was greater in Andean countries, Guatemala and Nicaragua, and only Uruguay, Canada and the islands of the Caribbean remained free of the disease. In 1991-1996, international financial assistance for preventive and control measures amounted to US$12 million. In Peru, where the epidemic originated, its economic impact was estimated to be US$150 million in the first year. It is also estimated that to provide water, sanitary and other basic services needed to eliminate the risk of the disease spreading throughout the region, would require an investment of US$200 million. Climate change in general, and the El Niño cycle in particular, seems to be connected to some of these epidemics (see the section on Atmosphere). Cyclical temperature and precipitation changes associated with El Niño are particularly important, as they could favour the development and proliferation of vectors of epidemic diseases such as malaria, dengue fever, yellow fever and bubonic plague (WHO, 1999). In South America, the most severe outbreaks of malaria have generally occurred in the year following the beginning of El Niño, whether in association with an increase in precipitation (as in 1983 en Ecuador, Peru and Bolivia) or, on the contrary (as in Colombia and Venezuela for several years), with a reduction in rainfall, resulting in run-off that permits the vector mosquito eggs to multiply. There have also been outbreaks of malaria every five years in Guyana and Suriname, suggesting a link to climate cycles. A similar link has been suggested between the warming of surface sea water by El Niño, the proliferation of marine algae and the outbreak of cholera in South America in 1992 (WHO, 1999; PAHO, 1998). In the case of dengue fever, more precipitation affects the density of the vector mosquito and its transmission potential, but there is less evidence of a connection with the climate, perhaps because other factors, such as prevalent immunity levels, counteract this. Too much or too little rainfall plays an important part in the transmission of water-borne diseases such as cholera, gastrointestinal infections and various types

·

of diarrhoea. There were outbreaks of cholera in Peru, Nicaragua and Honduras when El Niño caused an increase in rainfall in 1997-1998 (WHO, 1999; PAHO, 1998).

Technological disasters Almost 28 per cent of total mortality from disasters in Latin America and the Caribbean during the period was caused by technological events or threats (CREDOFDA, 2003). This percentage includes chemical spills, explosions, collapsed buildings and structures, poisoning and fires (excluding forest fires) which occur in residential areas, and not as a result of industry or transport, Disasters caused by technology cause serious human suffering, loss of life and long-term damage to a country’s economy and its productive capacity. Lack of measures to control transport and emissions or discharges from industrial processes can lead to serious accidents that endanger both human and environmental health. Threats include spills of hazardous substances like cyanide, mercury, petroleum and others that are corrosive, toxic, explosive, inflammable, and cause infections or discomfort. In the Orinoco delta and neighbouring regions in Venezuela gold mining has increased by 500 per cent over the past decade and the use of cyanide and mercury has grown proportionately. For example, three tonnes of mercury have been dumped into the Caroni River basin alone; moreover, in 1995 a millionand-a-half litres of waste polluted with cyanide was spilt into the Omai and Esequibo Rivers in neighbouring Guyana (Filártiga and Agüero, 2001; CSF, 2000). Some groups of people who live in the Amazon, Brazil and French Guyana have been found to have ingested high levels of mercury by eating fish polluted as a result of gold mining (UNEP Chemicals, 2002). The largest oil spill in the world was in 1979 in the Ixtoc oil well in Campeche Bay, Mexico, when more oil was spilt than from the Exxon Valdez (CIC, 2000). In Brazil and Colombia there is a long history of pipeline ruptures on land and coastal spills with serious environmental consequences. Two of the largest spills in Brazilian history took place in 2000: the first affected Guanabara Bay (see section on Coastal and marine areas); the second happened inland and was three times bigger, affecting the Barigüí and Iguazú Rivers. In Colombia, between 1986 and 2000, guerrilla fighters dynamited the country’s main pipelines 905 times, on several occasions also affecting neighbouring Venezuela (MDN, 2002). Fires often break out in buildings in large cities. The most frequent cause is overloading deficient or dam-

aged electric circuits, but they may also be caused by earthquakes. In Managua (Nicaragua) 77 per cent of deaths in the region during 1970-2001 resulted from technological accidents in fires that started following the earthquake of December 1972 (CRED-OFDA, 2003). Other fires in skyscrapers in Sao Paulo, Brazil, in 1972 and 1974, left about 200 dead (Kuroiwa, 2002). An emerging technological risk, with a potentially serious impact, is the pollution of crops such as maize — a staple food in the region and worldwide for large human groups and of prime importance to their economic activity, — with genetically-modified species (Munich Re Group, 2002). This has been demonstrated in Mexico (see section on Biodiversity).

The region’s vulnerability to disasters

are some of the elements that increase risks, especially when they are in highly dangerous areas (ECLAC, 2000). Finally, it must be remembered that there would be no significant losses if people or objects were not exposed to risks (Munich Re Group, 2001). It is urgent, therefore, that all future sustainable development plans should consider socio-economic and environmental vulnerability (ECLAC, 2000). In this respect, the poor must be given priority since they are the most vulnerable, suffer the greatest harm, and have fewer recovery options.

Impact of disasters

Although they seem to strike unannounced, disasters are to some degree predictable and their effects depend on human and environmental vulnerability (UNEP, 2002). In almost all cases individually minor events accumulate and interfere with the response capacity of natural systems, increasing their vulnerability. Although there is no immediately perceptible deterioration in how the system functions during this accumulation process, it becomes evident when the zone is struck by an event of greater magnitude.

The negative consequences of disasters extend beyond the short term and, on occasion, produce irreversible changes in economic, social and environmental conditions (UNEP, 1999b). Among them is the involuntary displacement, after disasters, of populations culturally rooted in the territory who become environmental refugees. Rescue and recovery operations themselves may destroy habitats and generate a huge amount of waste material. In many cases, ecosystems cannot recover as quickly as they need to,and are replaced by less resilient and diverse ecosystems less able to supply basic environmental services such as water purification, sediment retention, and protection against the rigours of the climate. The result is even greater vulnerability.

Together with natural threats — tectonic, hydrometeorological or biological (perhaps made worse by global climate change) — there are risks that come from human behaviour, often related to sustained population growth and poverty (Velásquez and Rosales, 1999). In the environment, these include changes in land use without proper planning (with the subsequent degradation of ecosystems), such as felling native forests to clear the land for agriculture, overexploitation of mountainsides for subsistence agriculture, building roads and urbanisation. This is done without account being taken of preventive, mitigation and environmental protection measures needed for sustainable land regulation (ECLAC, 2000).

The introduction worldwide of improved preventive, response and rehabilitation systems has meant less loss of human lives. However, the situation is becoming worse in two respects: hydrometeorological disasters are now more frequent — perhaps because of global climate change (IPCC, 2001; WHO, 1999) —and the economic effects of natural catastrophes are becoming more severe because of higher population densities and concentration of property (Munich Re Group, 1997; 1998). While the number of severe global disasters quadrupled between the 1950s and the 1990s, economic losses increased 15 times, reaching a total of US$652,300 million between 1990 and 1999 (Munich Re Group, 1997; 1998; 1999; 2000; 2001).

It has already been pointed out how in this respect the Caribbean — given its islands and hurricane belt climate conditions — is particularly vulnerable to hydrometeorological disasters, made worse by global climate change. Similarly, in South America, parts of the Brazilian northeast, the desert zones of Peru and Chile, and arid zones in Argentina, are also very vulnerable to a worsening of drought.

Following the world trend, during the period 19702001 there has been a notable drop in the region in the number of deaths from disasters. Total loss of life in the 1990s was 38 per cent less than during the 1970s (CREDOFDA, 2003). In particular, there was a dramatic reduction in losses from earthquakes: from 101,704 in the 1970s to 11,101 in the 1980s and 2,371 in the 1990s. This may be explained both by fewer serious earthquakes in densely-populated or highly vulnerable zones, and better preparation in some of the countries affected. However, the number of human lives lost because of hydrometeorological events tripled between the 1970s and the 1990s, reaching 59,610 in the latter decade (af-

In urban areas, vulnerability becomes worse because there are no proper controls or planning, buildings are badly constructed, and industries are located in urban zones where hazardous material is also stored. These

The catastrophe of small disasters A detailed assessment of the incidence of disasters in nine countries in the region (1988-1997) shows a total of 17,587 events recorded, almost 90 times more than the number registered in the joint database prepared by the Belgian Disaster Epidemiology Research Centre and the United States Office for Foreign Disaster Assistance (CREDOFDA), where only 196 events were recorded in the countries selected during those years. The studies were made in Argentina, Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Mexico, Peru and Panama. The impact of these events on lives lost is similar to that reported by CRED-OFDA, indicating that disasters with loss of life are well recognised in the CRED-OFDA register. However, the number of injured registered in the regional study is seven times greater than that registered by CRED-OFDA, and the number of people affected is almost double. About 83 per cent of deaths occurred in events where fewer than 100 people died. These results show that the thousands of small disasters that occur every year —although their impact and effect on infrastructure is not large enough to have them included in official statistics— in some way prepare the ground for bigger disasters. If the effects of all these local disasters are combined, the accumulation has considerable consequences on quality of life and resources in the communities where they occur. This reinforces the need for mitigation capacities and programmes and to include the search for local development and sustainability in national and international policies.

ter having descended slightly in the 1980s). Equally notable is the increase in the loss of life from epidemics, which was almost nine times greater in the 1990s than in the 1970s. Moreover, economic damage caused by natural disasters is increasing in the region; it quadrupled between the first decade and the third, from US$7,700 million in the 1970s to US$27,500 million and US$28,500 million in the 1980s and 1990s, respectively (CRED-OFDA, 2003). ·

Vulnerability ulnerability to disasters: a geo-referenced index for Honduras Among the main disaster vulnerability factors are existing environmental, demographic, social and infrastructure conditions. The CIAT-UNEP-World Bank Project contains a geo-referenced vulnerability index for Honduras that combines these factors with superimposed maps containing geographic information for each of them. To show environmental vulnerability, zones at risk of landslides and floods are delineated, using data on forests, rivers, topography, slopes, soil permeability and vegetation. The population vulnerability map has a graph showing demographic density by municipalities, while the social vulnerability map has data on incomes in the different municipalities according to their degree of poverty (severe, critical, medium and low). For the map on infrastructure, vulnerability data are used on electric cables and municipal roads, classified as primary, secondary and tertiary (using criteria on locality, quality, size of nearby populations, health centres and inclinations). The four maps are combined to show the 60 highest priority municipalities for disaster prevention and rehabilitation. The information allows precise answers to be given to questions such as:

Its objective to promote international cooperation in this field was strengthened by the Inter-American and world conferences on the reduction of natural disasters held in March and May 1994. In the 1980s, ministries of health throughout the region had promoted mechanisms to coordinate responses to different types of disasters. But it was in the 1990s when significant progress was made on a national, regional and international disaster prevention, mitigation and rehabilitation institutional and legal framework. Some countries in the region —Guatemala, Brazil, Panama, Chile and Costa Rica— created and strengthened independent systems to protect against disasters. They also promoted legal changes to extend their attributions to preventive action, although still dependent on international finance (PAHO, 1998). Together with national initiatives, efforts were made by sub-regional disaster prevention bodies in Central America and the English-speaking Caribbean. The Coordination Centre for the Prevention of Natural Disasters in Central America and the Caribbean and the Caribbean Disaster Emergency Response Agency — established in 1988 and 1991, respectively — strengthened and extended their activities. The first-named became an inter-governmental body in 1993. Regionally, in 1992 the process began to ratify the Inter-American Convention to Facilitate Disaster Assistance proposed by the Organization of American States, and sub-regional parliaments supported various legal initiatives on disasters. International organisations like the United Nations Department of Humanitarian Affairs and Médecins sans Frontières established regional offices for Latin America and the Caribbean. Starting in 1992 several non-governmental technical organisations were established including medical societies to deal with national emergencies, the Social Studies Disaster Prevention Network (1992) and the Inter-American Emergencies and Disasters Society (1996). In 1999, the Latin American Economic System created a regional techni-

153

cal cooperation mechanism for emergencies arising from natural disasters to assist Central American and Caribbean countries. This is designed to strengthen national and international assessment and coordination, analyse vulnerability and prepare mitigation and rapid assessment measures on damage and needs (SELA, 1999). Experience has shown the positive effects of planning and institutional capacity building to deal with disasters of all types. This combination of actions has also given greater breadth and depth to the strategic processes of information and education on the subject. The creation of the Regional Disaster Information Centre is outstanding in this respect, as are the various technical international conventions. A fundamental element in this respect is to strengthen regionally-standardised data methods, not only to prevent misunderstandings during emergencies, but also properly to assess losses following hurricanes, earthquakes, floods and other disasters. In this respect, the evaluation experience that the Economic Commission for Latin America and the Caribbean (ECLAC) has acquired over 30 years has produced a specific methodology to estimate socio-economic effects of natural disasters in Latin America and the Caribbean (CEPAL, 2002b). Also important are attempts to identify how vulnerable populations and territories are to natural and technological threats, such as the efforts made by the Red Cross for Caribbean countries. The United Nations Development Programme (UNDP) is trying to do the same with its Global Vulnerability Index programme.

International cooperation The international community has generally responded immediately to disasters in the region by providing help in emergency situations and reconstruction financing. However, in cases of natural disasters, more than 90 per cent of funds are allocated for rehabilitation, aid and reconstruction and only 10 per cent are spent on preventive measures (CEPREDENAC, 2002). During the 1980s and 1990s, Latin America and the Caribbean received 31 World Bank loans (32 per cent of the total) for US$2,491 million (38.3 per cent of the total for disaster mitigation and prevention in the region) (Kuroiwa, 2002). The Inter-American Development Bank (IDB) has approved US$1,500 million of new disaster financing during the past 10 years to help affected countries to recover, 10 times more than the annual average during the 15 previous years. In 1998 the IDB, through its Emergency Reconstruction Mechanism, created a source of financing for up to US$20 million per project to accelerate the re-establishment of services, finance temporary repairs and support clean-up work during the rehabilitation period (BID, 2000). The Assessment and Early Warning Division of the Regional Office for Latin America and the Caribbean of the United Nations Environment Programme deals with

environmental vulnerability by making assessments that help to pinpoint environmental hotspots. In 1998 it assisted in preparing environmental assessments on future development and reconstruction in Central America. Similarly, when Venezuela was lashed by floods in December 1999, in response to a request from the Ministry of the Environment and Renewable Natural Resources, it sent a mission to make a rapid assessment of the impact caused by the disaster. As a result, a series of workshops were held to increase Venezuela’s capacity to identify vulnerable regions and to be better prepared to cope with climate events (UNEP/DEWA, 2001).

An integrated disaster strategy The increase in environmental degradation and poverty during recent decades has made a large part of the regional population more vulnerable. Means are therefore being sought, internationally and regionally, to reduce vulnerability and impact not only by strengthening emergency attention bodies and systems, but also by focussing on non-structured prevention and mitiga-

tion. Risk prevention should be made part of sustainable development with local and community participation, with separate involvement by non-governmental organisations and citizen groups. Within this framework, a new vision emerges: development must cut risks by reducing the social, economic and environmental vulnerability of threatened populations and territories. In this case non-structured mitigation seeks to maintain or restore natural controls. For example, wetlands reduce flooding, forests prevent landslides and mangroves lessen the effect of coastal storms and extreme tidal waves. In general, good land use keeps ecosystems healthy, provides resources and facilitates nonstructured mitigation which is particularly attractive in countries where risk insurance and structured mitigation come at a high price (CEPAL, 2000). It is important to ensure that urban expansion does not extend to vulnerable areas by controlling soil instability and supplying adequate housing and environmental sanitation services (particularly for solid waste collection and disposal). It is also necessary to promote

Regional disaster early warning action Early warning of environmental threats may have either a short- or a long-term focus. The first responds when a disaster is imminent or has struck, such as floods, fires, volcanic eruptions and earthquakes, while the second is about increasing awareness of impending environmental problems, such as the impact of climate change and chemical products that affect human health. Another early warning system, complementary but more comprehensive, is to promote the preparation of a more complete analysis to encourage action to deal with environmental problems like those already indicated, and others that are less evident such as the shortage of water or the loss of biodiversity. The UNEP contributes to these efforts through its Division of Early Warning and Assessment, with projects such as the series Global Environment Outlook (GEO) and rural sustainability indicators for Central America (CIAT, UNEP and World Bank). Perhaps the follow-up to El Niño of 1997-1998 was the first time that global climate monitoring had the technical and policy capacity to warn authorities and the public about the probability of imminent changes (WHO, 1999). To enable this to be done, general climate models were used based on measuring and predicting ocean surface water temperatures. The United States National Oceanic and Atmospheric Administration (NOAA) promotes the periodic organisation of regional climate fora to discuss the state of the climate in the region and arrive at a consensus about forecasting. This knowledge may be used to take disaster preventive measures and for mitigation and rehabilitation. Within this framework, several countries in Latin America and the Caribbean such as Bolivia, Colombia, Ecuador and Peru have prepared specific emergency plans to prevent and mitigate damage caused by El Niño. The contingency measures include forecasting water supply needs in drought zones, improving water quality in flood zones, providing basic sanitation in temporary settlements, reinforcing epidemiological vigilance and administering disaster donations. In 1999, Central American governments approved a vulnerability and disaster reduction strategic framework, and a five-year plan to be coordinated by the Coordination Centre for the Prevention of Natural Disasters in Central America. The Centre has promoted the preparation of proposals for early warning systems for all countries in the area except Belize. The proposals are mainly concerned with problems caused by drought.

this view when it states that communities should become resilient in the face of natural or technical threats, reducing the social, economic or environmental vulnerabilities that cause them of. This will require making advances “to protect against threats by risk management and by integrating risk prevention into sustainable development” (ISDR, 1999).

El Niño of 1997-1998 in Peru: impact, prevention and damage mitigation In Peru, El Niño has had three levels of intensity: weak, moderate and strong. Weak intensity means, on average, an increase of 10-20 per cent in normal climate characteristics (light rain and some damage), moderate intensity shows an increase of 20-50 per cent (moderate rain, damage to agriculture and housing) and strong intensity is an increase of more than 50 per cent in normal climate characteristics (heavy rain, floods and huaycos, a local name for violent downpours that carry away mud, stones, trees and other landscape material).

In Peru, the El Niño of 1997-1998 caused economic losses of US$3,500 million, including losses of infrastructure (highways, bridges, water and sanitation system), production (fishing, mining, industry, agriculture and commerce) and services. An example of the impact of the phenomenon on economic activity was that fishery exports dropped by 76 per cent. However, it is important to note that on this occasion, for the first time, a total of US$218 million was invested in measures to prevent damage. These measures included preparing the physical infrastructure, training human resources and buying medicines and other inputs, among other specific measures. Investments of US$158 million were made to mitigate the damage. Of the funds managed by the Ministry of Health (US$18 million), 37 per cent was used after the event to rehabilitate affected health establishments, construct new buildings and cover the costs of treating diseases like cholera, malaria, dengue fever and others.

Environment and human health

T

his chapter shows the close relationship between the state of the environment in the Latin America and Caribbean region and the health of its inhabitants. The relationship between environmental risk factors and sanitary conditions in the region is summarised and developed within the context of how global epidemiology has changed over the past 30 years. Health risks are related not only to the natural or biological environment but also to the human environment (Smith and others, 1999; WHO, 2002a). Estimates show that at the beginning of the 1990s, of potential years of life lost in the region other than by accident, 11.0 per cent could be directly attributed to the following environmental causes (in descending order): ● ● ● ● ●

poor water supply and sanitary services; urban air pollution; agro-industrial chemicals and waste; indoor air pollution, and vector-borne illnesses (malaria).

At this time, the cost of environmental disease was 18.0 per cent in developing countries in general, and 4.5 per cent in industrialised countries (PAHO and UNEP/ROLAC, 2002). Here we shall examine the sanitary impact of ecosystem changes (water, soil, air) as described by Kochtcheeva and Singh (n.d.) and the specific GEO methodology perspective (see Page 14 ). Included are important subjects such as the influence of lifestyles, personal behaviour and occupational surroundings (WRI, 1998; WHO, 2002a).

Epidemiological and environmental risk transition In the 1970s – in developing and especially in developed countries – there was a clear link between the ageing of the population (demography) and the increasing importance of non-transmissible chronic and degenerative diseases (epidemiology) as a cause of death, strongly influenced by environmental factors It was also found that human activities caused environmental changes which in turn increased sickness and fatalities from the transmissible and infectious diseases prevalent in developing countries. Within this framework the connection between health and environmental changes caused by humans, particularly on climate or water and soil pollution was studied. Initially, the epidemiological analysis identified a connection between three elements or factors: the atmosphere, the host and the agent. In the atmosphere, susceptibility factors intrinsic to the disease were found: temperature, humidity, presence of chemical or physical agents in soil, air or water. In the host, there were intrinsic susceptibility factors: genetic, metabolic, endocrine. Agents were infectious organisms, physical, chemical or allergic substances, as well as dietary deficiencies or excesses.

·

This linear approach changed in the 1970s to one of multiple causes and effects, such as lifestyles, social or psychological surroundings, occupational risks and the response of health services (Laframboise, 1973; Dever, 1976). Since then it has become increasingly clear that health depends on the interaction between environmental influences, lifestyles and human nature. This idea of independence is directed at re-establishing a balance between people and the environment by taking preventive as well as curative measures. To achieve it requires profound changes in our social, economic and technological organisation. By 1990, chronic or degenerative diseases accounted for 86 per cent of all deaths, while only 6.0 were caused by transmissible diseases (WRI, 1998). This clearly shows the epidemiological transition in the developed world.

Epidemiological and environmental risk transition: the WHO approach During the 1990s, as a result of the international debate on environmental sustainability in the development process, the World Health Organization (WHO) adopted a new approach to analyze the relationship between health and the environment, and to develop environmental health indicators. This new approach is based on the pressure, state, response system used by the Organisation for Economic Cooperation and Development (OECD) to prepare environmental indicators. It also includes the notion of driving force (to identify underlying causes of environmental changes), exposure (to identify the way individuals are exposed to and absorb morbidity or mortality agents) and effect (to establish the consequences of exposure, whether subclinical or expressed as morbidity and mortality). According to the WHO analysis, in today's world a transition is taking place in environmental health risks: from traditional risks related to the impact of natural phenomena and insufficient development, to modern risks associated with some features of unsustainable development. In general, developing countries are exposed to both traditional and modern risks. Although these countries are immersed in an industrialisation process (subject, therefore, to modern sanitary risks like pollution and unhealthy lifestyles), the eventual benefits of development (such as more access to basic health services) do not reach the large marginalised sectors of the population also exposed to traditional sanitary risks. Traditional risks are usually a consequence of poverty or, as has been said, of exclusion from the benefits of development. Among these risks mention may be made of the lack of access to drinking water, inadequate disposal of excrements, domestic air pollution caused by dust, fungi and smoke from burning fossil fuels for cooking and lighting, contamination of food with pathogenic substances, exposure to the impact of drought, floods and earthquakes, contamination with lead from ceramics and paints, and accidents or illnesses caused by small-scale or artisanal agriculture and industry. The lack of food safety which is due to insufficient access to productive land, and subsequent severe nutritional deficiencies, must be mentioned as one of the traditional risks with most impact on much of the world's population in terms of morbidity and mortality. Modern risks mostly originate in industrial processes without sufficient safeguards to prevent or mitigate sanitary and related environmental problems. They include such dangers as; accumulation of hazardous solid waste; air pollution from industrial or vehicular emissions in urban zones; pollution of water resources with industrial or agricultural waste and urban sewage; the improper handling of chemical or radioactive substances used in new agricultural or industrial technologies; traffic accidents; emerging or reemerging infectious diseases; climate and atmospheric changes (such as depletion of the ozone layer and the greenhouse effect); violence or other psychological effects of the urban environment; and the abuse of drugs such as tobacco and alcohol.

Epidemiological and environmental risk transition: the WHO approach (continuation) (poverty, as mentioned, is a serious risk factor), but there are also individual factors, such as genetic and nutritional antecedents, sex, age and lifestyle. Children under five (even in the prenatal period), are particularly susceptible not only because they absorb more water and air in relation to their weight, but also because of how they eliminate substances —through still immature livers or kidneys—, as well as the high rate of cellular reproduction of their organisms, which makes them vulnerable to the effects of cancerous and neurotoxic substances. The latest WHO world health report gives detailed estimates on 27 risk factors, including their impact on global diseases, as well as on mortality and incapacity. Among the risk factors analyzed five are defined as being specifically environmental: unsafe water, health and hygiene; urban air pollution; domestic smoke from solid fuels; exposure to lead; and climate change. Other risk factors include poor nutrition in children and mothers, as well as carcinogens and air particles in the workplace, and are also related to the environment. Sources: WHO, 1997, 2002a; Corvalán and others, 1997; Briggs, 1999; Smith and others, 1999; Chelala, 2000; Kay and others, 2000; PAHO, 2002.

The same trend is seen in developing countries, although to a significantly lesser extent: in that year chronic diseases caused 47 per cent of deaths, and transmissible diseases 42 per cent. Unlike earlier periods, chronic diseases in these countries now cause as many deaths as transmissible diseases.

monitoring and control of pollution; preventive public education; a new sense of social responsibility by the business sector; and new legislation and incentives to prevent sanitary risks from occurring (Capra, 1985; WHO, 1997; Briggs, 1999).

In the Americas at the end of the 1990s, non-transmissible diseases accounted for 49.7 per cent of adult deaths. On the other hand, the potential years of life lost in Spanish-speaking Latin America and the Caribbean from these diseases was put at 48 per cent, with 30 per cent due to transmissible diseases and maternal and perinatal causes (Castillo-Salgado, 2000).

Anthropogenic degradation of nature and health risks

This epidemiological transition is also related to an environmental health risk transition from traditional risks related to the impact of natural phenomena and insufficient development to modern risks associated with features of development itself (WHO, 1997; Chelala, 2000). The principal driving forces behind that risk transition are linked to growing populations, urbanisation, the relative weight of poverty and inequality, how science and technology have developed and the production and consumption patterns that are features of economic development processes in today’s societies. The most significant possible sanitary effects found include – in different degrees according to when the transition occurs – acute respiratory infections, intestinal infections and diarrhoea (emerging and re-emerging), injuries and poisonings, chronic respiratory, cardiovascular and mental illnesses, and malign neoplasms. Because of the many factors these processes involve, responses to environmental health risks go beyond strictly sanitary or sectoral measures. They include: an integrated approach towards changing social and economic policies aimed at meeting the population’s basic needs; the use of clean technologies; risk management; ·

From the point of view of environmental changes and their implications for the epidemiological transition, it is important to give a general idea of how anthropogenic degradation of natural ecosystems may lead to human health risks. From an ecosystem point of view, three large groups of environmental risk factors are important: water, soil and air (Kochtcheeva y Singh, n.d.).

Water impact Drinking water pollution is the most serious result of the degradation of the aquatic ecosystem. The transmissible diseases: amoebic dysentery, hepatitis A and E, shigella dysentery, paraphytic fever, typhoid fever, rotavirus and cholera infections (PAHO, 1998) are spread in untreated or inadequately–treated water or water contaminated with excrement. Water quality may also be affected by chemical substances such as nitrates (from fertilisers and septic tanks), arsenic, lead and persistent organic pollutants. There are now 100,000 synthetic compounds in use that may reach the aquatic environment and accumulate in the food chain. These persistent compounds are very harmful to ecosystems and human health (EHN, 1997). Human health is also seriously affected by the damage done to coastal waters and the ocean depths; when sewage is discharged into the sea, pollution may con-

taminate neighbouring beaches, causing diarrhoetic, skin and mucous ailments. In the Gulf of Mexico there have been cases of gastrointestinal infections, irritation of the skin and eyes, poisoning and hepatic dysfunction as a result of contact with sea water (Kochtcheeva and Singh, n.d.). These risks are made worse by lack of access to drinking water and basic sanitation (although, on the other hand, excessive levels of fluoride used to make water potable are also associated with some forms of cancer and dental fluorosis) (PAHO, 1998). It is estimated that in 1990 this caused a lowering of life expectancy in the region by 5.5 per cent (PAHO and UNEP-ROLAC, 2002). It is also estimated that each percentage point of increase in access to safe drinking water would prevent one in every 1,000 newborn infant deaths (PAHO, 2002). Between 1971 and 1998, the percentage of the regional population with domestic water supply (or easy access to water) went from 53 to 85 per cent; this means that today one-seventh of the regional population is still without access to this resource (OPS, 2001). Furthermore, PAHO reports that 60 per cent of the regional population with household water are connected to systems that operate intermittently and where control, sani-

tary monitoring and quality certification measures are almost non-existent. This means they must take constant care to avoid getting diarrhoea and other waterborne sicknesses caused by unsafe water. Only 24 per cent of the regional population has effective water quality monitoring systems (PAHO, 1998). PAHO also points out that the systems defined as “of easy access “ generally represent a significant health risk, especially for children and the elderly (OPS, 2001). Access to sanitation systems rose from 59 to 79 per cent of the population between 1980 and 1998 (there are no data for earlier years), but 86 per cent of the population covered in the last year were connected to drainage systems with no effluent treatment. Only 13.7 per cent of sewage collected is treated in any way, and where treatment is given it is very inefficient (OPS, 2001). Another sanitary risk related to water resources is acidification of surface waters (mainly lakes and reservoirs) caused by sulphur dioxide emissions from heavy industry and motor vehicles, facilitating the flow of heavy metals and allowing their concentrations to rise to harmful levels in water for human consumption. Although up to now this risk has been seen mainly in industrialised countries of North America and Europe, by 2050 extensive zones in Brazil, Colombia, Mexico and

Peru could be faced with the impact of acidification (SEI, 2002).

Infections related to lack of drinking water water, sanitation and poor hygiene (as a percentage of the total potential years of life lost through incapacity)

Infectious intestinal diseases – as a cause of Years of Potential Life Lost (YPLL) from premature death or incapacity — fell from second place in 1980 (10.2 per cent), to 10th place in 1994 (3.7 per cent); this 70 per cent drop is related to wider use of oral hydration, more breast feeding and better supply of drinking water (PAHO, 1998). However, in countries such as El Salvador and Paraguay YPLL from intestinal infections is still serious and requires constant attention to fight diarrhoea and other water-induced sicknesses (PAHO, 1998). It is also important to point out that prevalent infant ailments, mainly diarrhoea and acute respiratory infections, account for the highest number of visits to health services and are a major cause of hospitalisation (PAHO, 1998).

Impact of soil degradation With respect to degradation of land ecosystems, the main risk factors are destabilisation and pollution of soils resulting from deforestation, expansion of agriculture and mining.

Less rainfall, higher air temperatures, more flooding: when trees are cut the climate becomes progressively more arid and the soil loses its capacity to absorb and retain water and release it slowly.

Solid waste and associated health risks Estimates put the potential years of life lost in 1990 attributable to agroindustrial chemicals and other wastes at 2.0 per cent. Industrial waste may be combined with domestic waste and expose the population to chemical or radioactive risks. Uncollected organic waste causes risks through fermentation and creates conditions in which pathogens can survive and multiply, especially when they are mixed with faecal residues as a result of inadequate elimination of excrements. Organic waste may also be a natural medium for insects, rodents and animals that are neither totally pathogenic nor pathogen carriers, to survive and reproduce. Uncollected solid waste may obstruct the flow of water, resulting in floods or leaving stagnant water behind which provides a favourable habitat for vectors of water-borne or tropical diseases. Numerous groups are at risk: the population in areas without services, especially pre-school children (exposed when they come into contact with uncollected waste while playing); those who handle the waste (formally or informally); workers in companies producing toxic or infectious materials; people living near solid waste dumps. But even when solid waste is collected, the population may be exposed to serious health risks if there is no proper disposal. Drinking water may be contaminated with chemical or microbiological agents if the waste is thrown into rivers or onto vulnerable aquifers. Disposal of solid waste in rivers, lakes or seas may also result in toxic substances being accumulated into the food chain and absorbed by plants and animals. Sources: WHO, 1997; PAHO and UNEP/ROLAC, 2002.

sands of cases of acute poisoning throughout the region and have potentially long-term cancerous and mutagenic effects. In addition, this type of agriculture severely upsets the balance of ecosystems’ flora and fauna, and favours the proliferation of pests that may have harmful effects on health (see section on Land). As already mentioned, extensive use of fertilisers harms not only soils but also bodies of water (surface or groundwater). Other agricultural wastes or residues also have similar impacts. Persistent organic compounds used as pesticides are not easily degraded and remain for many years in the atmosphere, accumulating in the higher food chain levels, in animal and human tissues, interacting with the endocrine system and hormones, affecting reproductive processes and development and causing neurological and immunological damage to humans and other animal species (UNEP, 2000). Heavy metals such as lead and mercury are polluting the soil, water sources and the air. As has already been indicated, in many cases these metals come from mining in countries such as Bolivia, Brazil, Colombia, Peru, Suriname and Venezuela. It is important to note that there has recently been a worsening of malign neoplasms and congenital anomalies in the region, two conditions linked (among other possible causes) to chronic exposure to chemical pollutants (PAHO, 1998).

·

Impact of air composition and atmospheric changes Climatic events and the composition of the air may have an important sanitary impact on the atmosphere. As pointed out in the section on Atmosphere, besides extreme pollution due to vehicular and industrial emissions, there is also indoor air pollution from cigarette smoke, organic particles, (pollen, insects, microorganisms), non-biological particles including smoke, lead, carbon oxide, asbestos and other synthetic chemicals. Indoor air degradation is associated with various sanitary effects: irritation of the tissues, chronic pathologies and different types of cancer (WHO, 1999b). It is estimated that by 1990 urban air pollution was responsible for three per cent of YPLL in Latin America and the Caribbean (PAHO and UNEP-ROLAC, 2002). The type and level of indoor air pollution depends above all on the source of energy used to prepare food and to light buildings. In Latin America, only a fifth of the population uses biomass, a traditional risk factor; although this is the second lowest proportion in the world – after countries with developed market economies – it represents 80 million people (WRI and others, 1998). In some parts of South America, more than 50 per cent of the population use solid fuel for cooking (WHO, 2002a).

Chapter 2: State of the Environment in Latin America and the Caribbean, 1972-2002

Environment Outlook

The most serious outdoor air pollutants are ozone, sulphur dioxide, nitrogen oxides, suspended particles, carbon monoxide, lead and other metals that come from vehicular emissions, energy generating fuel plants, petrochemical plants and refineries (WHO, 1999b; Yassi and others, 2002). The critical effects of these substances include pulmonary irritation, interference with foetal growth and infant development, facilitating viral infections, bronchitis and pneumonia and worsening heart problems, asthma and emphysema (WHO, 1999b). In 1992 some 76 million people in urban areas of Latin America such as Sao Paulo, Rio de Janeiro, Santiago and Mexico City were exposed to air pollutants that exceeded the maximum limits recommended by the World Health Organisation. In Sao Paulo and Rio de Janeiro, these levels of pollution resulted in 4,000 annual cases of premature death (CETESB, 1992). In Chile, Mexico and Brazil an increase of 10 microgrammes per cubic metre of suspended particles has been observed to coincide with increases of 0.6 to 1.3 per cent of deaths in persons over 65 (PAHO, 1998). It is estimated that, over the next twenty years, air pollution may produce 140,000 premature deaths per year in the region (Lvovsky, 2001). Air pollution caused by forest fires also has a serious impact on the health of the region’s population.

The fires are the direct cause of death and injuries, and also release particles of various sizes, and other substances that have severe sanitary consequences (such as carbon monoxide and dioxide, polynuclear aromatic hydrocarbides, aldehydes, organic acids, volatile or semi-volatile organic components and ozone). Fires in Brazil in 1997 caused an increase of 40 per cent in respiratory ailments in Manaus and account for 10,000 hospital visits in the Amazon region (Cochrane, 2002). Another impact of air pollution is the depletion of the ozone layer, particularly in the southern hemisphere, where the process is more severe (see section on Atmosphere). The rise in ultraviolet radiation increases the risk of cataracts and skin cancer and harms immunological functions (PAHO, 1997). Finally, the impact of atmospheric problems related to climate change (see section on Atmosphere) must be considered. These cause extremes of temperature and precipitation, and also contribute to the increase in transmission of diseases (cholera, gastrointestinal infections and different diarrhoeas), associated with the quality of water for human consumption and the development and proliferation of epidemic disease vectors (such as malaria, dengue fever, Chagas disease, yellow fever and bubonic plague). These changes shorten the pathogen’s incubation period, speeding up the infectiousness of the

Health impact of air pollutants Pollutant

Health impact

Sulphur dioxide

Causes coughing and affects the lungs. In Chile a comparison was made of different areas with 3 3 different environmental levels of SO2 (70 g/m vs. 130 g/m three-year annual average); there was more prevalence of chronic respiratory symptoms in the zone with the highest annual average (30% vs. 14% for chronic cough and 14.3% vs. 6.1% for breathing difficulties).

Carbon monoxide

Affects foetal growth and organic growth in children.

Nitrogen dioxide

Increases possibility of viral infections: lung irritation, bronchitis and pneumonia. In Mexico City a longitudinal study of emergency hospital visits by children under 15 found daily NO2 levels to be related to upper respiratory tract infections.

Ozone

Irritates the respiratory system and worsens cardiac problems, asthma, bronchitis and emphysema. Several studies in México City show the association of acute daily concentrations of O3 with respiratory health. In addition, studies on animals and humans have shown that O3 increases permeability of the respiratory tract, causes inflammation of the tract and reduces bacterial capacity, leads to structural changes in the lungs and accelerates their ageing.

Suspended particles

In Chile and Mexico an increase of between 0.5 and 0.8% has been found in daily deaths as a 3 result of an increase of 10 g/m in total suspended particles of less than 10 micrometers (PST10) in diameter; in Sao Paulo, deaths in people over 65 increased by 3%. In Chile, studies to determine the impact of suspended particle pollution in respiratory emergencies and visits to doctors also suggest a positive association. Similarly, a correlation has been found between infant mortality from pneumonia and a reduction in infantile lung function in Rio de Janeiro and Cubatao, Brazil.

Lead

Affects the circulatory, reproductive, nervous and kidney systems; produces hyperactivity and learning problems in children. Studies in Mexico found that the concentration of lead in the mother's bones has a negative correlation with the newborn's weight, and that the level of lead in the blood is also negatively correlated with the intellectual coefficient of children between 9 and 12 years of age.

vectors. The rise in temperature also accelerates the vital cycle or allows the vector to colonise areas that used to be colder. The temperature, by modifying exposure conditions, also affects human behaviour (WHO, 1999a).

The impact of environmental risks on sanitation Available sanitary data for the region indicate that some causes of morbidity and mortality in Latin America and the Caribbean may be related, to a greater or lesser extent, to environmental risk factors such as those analysed above. Among these are acute respiratory infec·

tions, intestinal infectious diseases, nutritional deficiencies and anaemia, malign neoplasms, perinatal and congenital conditions (Smith and others, 1999; PAHO, 1998). Acute respiratory infections frequently begin when people inhale air polluted with emissions from industrial, vehicular or biomass sources. Drinking water or eating food contaminated with faecal matter is the most serious cause of intestinal infectious diseases. Nutritional deficiencies and anaemia are related to the lack of access, and not only by low income groups, to productive environmental resources, such as fertile land. Finally, both malign neoplasms and perinatal conditions as well as – to a lesser extent – congenial anomalies, may be related to chronic exposure to chemical pollutants.

Chapter 2: State of the Environment in Latin America and the Caribbean, 1972-2002

Environment Outlook

Global estimates indicate that between 25 and 33 per cent of potential years of life lost through premature death or incapacity may be attributed to environmental risk factors (the environmental disease cost) with a greater impact on children under five (Smith and others, 1999).

Risk transition An analysis of how these causes of morbidity and mortality evolve clearly shows the dual epidemiological and environmental risk transition in Latin America and the Caribbean. Deaths caused by traditional risks

Health impacts of El Niño A probable symptom of the impact of human activities on climate change is the unusual frequency and duration of the El Niño phenomenon in the past fifty years (IPCC, 2001b; see section on Atmosphere). There is evidence that El Niño is associated with increasing the effect of natural disasters and the number of victims in various regions of the world, including Latin America and the Caribbean (WHO, 1999a) (see section on Disasters). For example, the effect of El Niño along the western coast of South America is very strong, particularly in Peru and Ecuador. Almost all the El Niño episodes are accompanied by very heavy rain in that region. During the 1997-1998 El Niño, in Piura, in the north of Peru, for 12 days rainfall was equal to half the normal annual precipitation, and in Talara there was one day when rainfall was five times that amount; 22 of the country's 24 departments suffered a severe impact with 67,068 families affected and more than 20 000 dwellings destroyed (WHO, 1999a). Disasters like these have an additional impact on the risk of death, by displacing the affected populations and by overcrowding in some places, at times for long periods. Mental and neurological disorders caused by stress were responsible for 10 per cent of the total potential years of life lost from all diseases and accidents in 1990, a figure which rose to 12 per cent in 2000 (WHO, 2001). A growing number of studies also show El Niño to be associated with changes in the risk of infections transmitted by vectors that nest in stagnant water. The most serious malaria epidemics in South America have generally occurred in the year following the beginning of an El Niño event. They are associated with either increased precipitation —for example in Bolivia, Ecuador and Peru in 1983— or with reduced rainfall and run-off (as in Colombia and Venezuela in several years), that favour the multiplication of the mosquito vector's breeding grounds (WHO, 1999a). In Guyana and Suriname epidemics have been reported at intervals of five years, which suggests a link with climate cycles. In the case of dengue fever, there is less evidence of a correlation: although also linked to increased precipitation that affects the density of the mosquito vector and its transmission potential, it may be counterbalanced by other factors such as prevailing immunity. Extreme precipitation (too much or too little) is also a serious cause of spreading faecal-oral transmission infections when water and food are contaminated with faecal material. Examples are cholera, typhoid fever, gastrointestinal infections and various diarrhoeas. In Honduras, Nicaragua and Peru there were outbreaks of cholera related to increased rainfall associated with El Niño in 1997-1998 (WHO, 1999a; PAHO, 1998). Floods may be followed by these diseases if stagnant water is contaminated with human or animal waste. In the case of drought, on the other hand, there is less water available for washing and hygiene and the risk of becoming ill is greater (WHO, 1999a). Finally, a possible link has been suggested between warming of surface ocean water by El Niño and the proliferation of marine algae that poison the shellfish people eat (PAHO, 1998; WHO, 1999a). Another regional concern associated with El Niño is the impact of suspended particles in winds coming from the African desert, which reach the Caribbean and affect human health and natural ecosystems. These winds are a consequence of worsening drought in western Africa linked to El Niño. In places like Barbados and the Virgin Isles, the sand contains African pathogens capable of infecting plants, animals and people (WHO, 2003).

(nutritional deficiencies and anaemia, infectious intestinal diseases, acute respiratory diseases) are decreasing. In contrast, causes linked to modern risks (malign neoplasm, congenital anomalies) tend to increase (PAHO, 1998, 2002; WHO, 2001). As far as changes in epidemiology are concerned, in Latin America and the Caribbean, chronic non-trans-

missible diseases have become more serious among adults from 45-64 years of age in recent decades because of the ageing population and changes in lifestyles (PAHO, 1998). The main cause of death is moving away from the circulatory apparatus and towards tumours. Adolescent mortality is mainly due to external causes (accidents, violence), although malign tumours are also significant.

Vector ector borne diseases Although the regional impact of transmissible diseases has diminished in recent years, the incidence of vector-borne diseases has increased in Latin America and the Caribbean. The first epidemic of dengue fever and hemorrhagic fever, and the presence of four dengue fever virus serotypes were reported simultaneously in 1779-1780 in Asia, Africa, and America. But in America the disease was virtually eradicated when yellow fever, which is transmitted by the same mosquito, was eliminated. There were serious outbreaks again in the 1960s in tropical areas in the region, and dengue fever is also returning to sub-tropical areas. The re-appearance of dengue fever has caused much suffering in countries like Cuba and El Salvador. In Havana, the outbreak began in mid-2001 and only disappeared in March 2002, highlighting the severe environmental problems caused by the accumulation of garbage in household backyards and empty spaces. Overcrowding in zones without clean water, drainage systems and garbage collection services creates ideal surroundings for mosquitoes, which need stagnant water to deposit their larvae, to breed. Other main diseases transmitted by insects in the region are malaria and Chagas disease. On the American continent, 36 million people live in areas where there is a high risk of malaria. The greatest incidence of this disease occurred between 19941999 in Colombia, Ecuador, Guyana, French Guyana, Peru and Suriname. Factors such as resistance to antimalaria drugs, migrating workers, rapid urbanisation of new or rural areas, among others, are thought to contribute to the continuous reports of malaria in the region (Feola and Bazzani, 2001).

The Tripanosoma cursi infection is transmitted to the human population by various species of the Triatominae family (such as Triatoma infestans in Argentina, Bolivia, Brazil, Chile, Paraguay, Peru and Uruguay, and Triatoma dimidiata in Mesoamerican countries), Rhodnius pallescens in Panamá and Rhodnius prolixus in Colombia, Venezuela and Mesoamerican countries.

Between 10 and 12 million people in Central and South America are infected with Tripanosoma cursi, and 50 million in the region are at risk. The ecology of the vector must be known to understand the epidemiology of the disease and propose control measures. Conventional control and elimination measures with medicines and pesticides have negative environmental effects and make the parasites immune. On the other hand, it is now recognised that improving housing is an efficient way to control and eliminate these diseases. Source: Health Cuba, 2002; PAHO, 2002; OPS, 2001; WHO, 1999a.

Transmissible diseases and conditions arising during the perinatal period (among which maternal-foetal malnutrition is very serious), taken together, were the most important causes of infant mortality from 19601994 (PAHO, 1998). However, death rates from transmissible diseases dropped by 75 or 80 per cent during that period, and only in Ecuador, Nicaragua, and Paraguay were they more important than perinatal infections in infant mortality. As for causes of mortality related more closely to environmental risk factors, from 1980-1994 deaths from nutritional deficiencies and anaemia fell in those under 25 (PAHO, 1998). Deaths and YPLL due to acute respiratory infections also dropped in children under 10 during the same period. On the other hand and as mentioned above, rates of malign neoplasms rose, especially in women and those over 25 or 30 years of age. Finally, mortality from congenial anomalies remained stable or grew in many countries; only in two sub-regions – the English-speak-

ing Caribbean and Brazil – do they not appear among the 10 main causes of death.

Regional disparities It is important to stress that countries in the region are divided into two large groups, according to present main causes of mortality (WHO, 2002a). In those with high infant and adult mortality (Bolivia, Ecuador, Guatemala, Haiti, Nicaragua and Peru), transmissible diseases, maternal and perinatal conditions and nutritional deficiencies cause 36.4 per cent of deaths (with infectious and parasitic diseases causing 59.9 per cent of these), non-transmissible diseases account for 52.9 per cent of deaths, and injuries cause 10.5 per cent. In the remaining countries (except Cuba),with low infant and adult mortality, however, transmissible diseases account for only 18.5 per cent of deaths, and non-transmissible diseases for 69.1 per cent (with more incidents of cardiovascular diseases, malign neoplasms, respiratory diseases and diseases of the digestive appa-

ratus); injuries explain 12.4 per cent of the remaining fatalities. Cuba is in another continental category, with Canada and the United States, of very low infant and adult mortality; in this group, transmissible diseases represent only 6.3 per cent de deaths, non-transmissible diseases 87.3 per cent and injuries 6.4 per cent.

Regional responses to environmental health problems As indicated above, the complex relationship between environmental changes and human health requires a broad cross-sectoral and preventive approach (PAHO, 1998, 2002; WRI, 1998; WHO, 2002a). Coordination is needed between the environmental, sanitary, energy and transport sectors, among others. To reduce substantially sanitary risks – going beyond immediate needs and clinical interventions – underlying causes must be dealt with: improving drinking water supply and sanitary systems, adopting more healthy nutrition and better lifestyles, changing to non-polluting technologies and, above all, getting rid of existing inequalities - it is the poor that are most exposed to environmental risks. Following the United Nations Conference on the Environment and Development, held in Rio de Janeiro in 1992, the subject of health and the environment in development has been treated at the highest regional and sub-regional levels: at the four Summits of the Americas (1994, 1996, 1998 and 2001) and at the Pan-Ameri-

can Health and Environment Conference (1995). To comply with a commitment made at the 2001 summit, Ministers of Health and of the Environment of the Americas (HEMA) met in March of 2002 in Ottawa and produced a ministerial communiqué that determined eight priority areas and 12 initial goals on health and the environment in the Americas (Environment Canada, 2002). The ministers also agreed to establish a working group with representatives from countries in the Americas to propose a follow-up procedure for ministerial decisions, together with other regional organisms (among the, the PAHO, UNEP, OAS and IDB). The HEMA Taskforce Group began its task in May 2003 and will complete its mandate by the end of the year. On a sub-regional scale, an action plan on health and the environment has been prepared within the framework of the Central-American Sustainable Development Alliance. The national working groups that further these action plans are usually multisectoral and have broad government and non-government representation. Two complementary activities — with examples in all countries of the region – are the healthy municipalities movement and the health promoting schools , as well as other initiatives by healthy citisens or communities (PAHO, 1998, 2002). In all these experiences the common denominator is work between sectors and institutions, as well as social participation by community groups, with an important and growing impact on understanding the complex relationship between health and the environment, and the need for a preventive or integrated approach.

Pan-American Health Organization: regional cooperation projects in the field of environmental protection and development, 2000-2001 In the two-year period 2000-2001, the Pan-American Health Organization assessed 62 regional technical cooperation projects, 238 technical cooperation projects in countries and 37 management support projects. Of the regional projects assessed, four were classified as environmental protection and development : water supply and other basic sanitation activities; workers' health; environmental health risks and chemical safety and, finally, inclusion of health aspects in environmental management. These projects were assessed according to how they complied with the 12 indicators of which all but two were considered to have been totally achieved, one was not achieved and was postponed and the other was considered to have passed expectations. Below is a table with the results of the assessment

Strategies proposed emphasise protecting the integrity of the environment by furthering sustainable development through cross-sectoral action (OPS, 1997). In this framework, the Pan-American Health Organisation (PAHO) has prepared a public health approach that integrates all its essential functions – disease prevention, vigilance and control, health promotion and monitoring, protecting the environment, legislation and regulations, management – in the different fields of action pro-

·

posed, such as environmental and occupational health. (Muñoz and others, 2000). With this new approach, sanitary authorities in the region have recently begun to show more systematic concern for air pollution risks, and for more integrated forms of management. In 1996, for example, the PAHO prepared a proposal for environmental vigilance by local health systems, designed to assess environmental

Environment Outlook

and socio-economic systems with rapid assessment methods and environmental techniques. The proposal – concentrating on vulnerable population groups and risk exposure – includes analysing water, soil and air, including sources of solid waste, pests, noise, energy and radiation. Environmental management is promoted through promoting environmental impact assessments, issuing licences for activities and controlling polluting activities. In this respect, PAHO has reported that in 1998 bacteriological analyses were carried out by 74 per cent of national centres; 45 per cent made chemical water analyses, and between 25 and 30 per cent were able to Get results concerning pesticides, herbicides, organic residues and heavy metals (PAHO, 1998). Also within the framework of this new approach, support has been given to legal environmental reforms, both of a general nature as well and on specific pollutants. Thus there are now regulations in place on vehicular toxic gas emissions in Chile (1994), Uruguay (1995) and Guatemala (1996); on arsenic in Chile (1994); and on lead and petroleum in Panama (1995). In Mexico and Belize regulations have been issued on environmental protection (1996); and on control of pesticides in Costa Rica (1994), Guatemala (1994) and Belize (1995). In 2000, Central American countries agreed to restrict the use of highly toxic pesticides and began the process of prohibiting the use of 107 additional pesticides, many of which are already prohibited outside the area but are still legal there (Chelala, 2001). Technical standards have been approved to guarantee drinking water quality in Honduras (1994), Peru (1994), Panama (1995), Venezuela (1995) and Antigua and Barbuda (1996), while in Mexico the National Water Regulation was approved (1994).

173

Nevertheless, enormous challenges remain in relation to access to drinking water and sanitation, undoubtedly the key environmental components in a preventive sanitary policy. Fifteen per cent of the population still has no access to drinking water and 21 per cent totally lacks sanitation services (PAHO, 2001). Coverage of drinking water supply has dropped in countries such as Brazil, Venezuela, Bahamas, Trinidad and Tobago, and in others, such as Haiti and Paraguay, it is less than 50 per cent (PAHO, 2001). Another fundamental challenge, the inclusion of the environmental health approach in macroeconomic and cross-sectoral policies, is far from becoming reality, with preference still being given to the use of intensive fossil fuel technologies and toxic inputs in agriculture and industry. In spite of the growth during the past decade of the public social cost share in the regional gross domestic product, levels of poverty and the number of poor have remained stable, and their social needs remain unsatisfied. As pointed out by the PAHO, “since most health sector reforms have centred on changes in financing and the organisation of health services for individuals, with few including concrete components to improve environmental health, there is a real risk that this will be relegated to mere declarations” (PAHO, 1998).

Latin America and the Caribbean

Conclusions Two important conclusions can be drawn from an analysis of the state of the environment in Latin America and the Caribbean during the period 1972-2002 and these, in turn, raise new questions. The principal conclusion is that environmental deterioration has worsened over the past 30 years. This is visible in critical areas such as the loss of forests and biodiversity, soil and water degradation, urban pollution, the present high level of human vulnerability to environmental change, and the effect all this has on the health of the regional population. Available estimates indicate that the high rates of deforestation in the 1970s have been reduced although they have not been halted. It is true that greater efforts have been made to conserve biodiversity, as shown by the greater number of protected areas. However, the pressures that lead to changes in land use, such as the expansion of deforested and urbanised areas, continue to cause the loss of habitats vital to maintaining biodiversity, and thus more ecosystems and species are threatened. Meanwhile, the technical and financial limitations imposed by poor fiscal policies and restricted government budgets mean that there is little effective preservation of socalled protected areas. The problems of the green agenda (related to biodiversity degradation) are not, however, the only ones – or even the main ones – that now afflict the region. An analysis of the situation of freshwater, land, coastal and marine areas, ur-

·

ban areas and atmosphere makes this clear. The brown agenda is another problem, linked to poor treatment of urban and industrial waste, and pollution of soil, water and air as a result of the use of agrochemicals, industrial activities and motor transport. These problems have reached crisis levels in many of the region’s most industrialised or urbanised zones – mega cities like Mexico City, Sao Paulo, Rio de Janeiro and Buenos Aires —, or in areas where for years highly intensive agriculture has used agrochemicals. In countries with medium-levels of urbanisation, or where there is less industrialisation, there are still many items pending on the brown agenda. The close connection between these problems and human health makes it even more urgent to seek solutions. However, linking them to deep-rooted patterns of production, distribution and consumption raises huge barriers that will have to be demolished. The regional economy has gone through many ups and downs over the past 30 years that have not levelled out into a path that leads to sustainable human development. The weight of the foreign debt, problems in financial markets (Mexico in 1995, Brazil in 1999, Argentina and Uruguay in 2002), and low incomes and employment (which only managed to match the rates recorded at the beginning of the 1970s), highlight the weaknesses of the growth patterns followed over the past three decades. Although certain economic indicators have recovered – and advanced in some countries - in almost all cases the achievement went hand in hand with

Environment Outlook

impoverishment and deterioration of the social and natural environment. Distribution became more and more unequal almost everywhere, and corruption and social violence increased. It must not be forgotten that social deterioration makes people more vulnerable to the natural or technological risks analysed in this chapter. This chapter’s second main conclusion is positive. As is reflected in its different sections (and already mentioned in chapter 1), the environmental agenda has become more internalised in Latin America and the Caribbean during the three decades since 1972. This is translated into the emergence and development of legal and institutional frameworks to deal with the environmental problem, as well as policies designed to counteract the most serious signs of deterioration. This has meant more state regulations, as well as more participation by the private sector and civil society, especially during the past 10 to 15 years. The return to democracy, after long years of authoritarian regimes in many countries in the region, has provided excellent opportunities to take action on the environment. More transparency and access to information, as well as the deterioration of the environment itself, have awakened increased public awareness about the impact of present production and consumption patterns, and led to more people becoming involved in the search for solutions. Forest preservation and biodiversity have attracted public attention and influenced govern-

177

ment policies, thanks in part to the support of international agencies and organisations which specialise in this field. As a consequence, more action has been taken to create and maintain protected areas, and to control trade in species. Pollution, and the productive processes that cause it, are gaining recognition, specifically as a result of the impact on the environment of regional growth in recent decades. Problems of water quality, solid waste and urban air pollution, attract increasing attention from the public, politicians and civil organisations or the private sector. There are also growing levels of public concern about the human health impact of these problems, a subject likely to highly motivate citizen action, especially in anticipating and coordinating public policies. Thus, the notion and practice of integrated environmental policies begin to take shape, not only with but also between other policy sectors (health, education, infrastructure) and macroeconomics sectors (trade, fiscal, monetary). Chapter Three goes into greater detail about the mechanisms by which environmental policy has developed in Latin America and the Caribbean from 1972 to 2002. This detailed analysis supports a review of the conclusions presented here, gives a clearer idea about possible solutions, and compares them with the medium-term possible scenarios, set out in Chapter Four.

Policy responses to environmental problems

L

atin American and Caribbean countries have taken an active part in defining and developing various important global non-binding multilateral agreements and instruments established over the past three decades. The countries’ participation in the agreements and the evolution of national environmental problems have encouraged them to introduce legal, policy and institutional reforms in different fields, to implement which they have had recourse to a variety of financial sources and economic instruments, as well as to new mechanisms on information, education and citizen participation. In these 30 years, the environmental initiatives have dealt with the most pressing concerns about the environment. For example, there are international agreements on the marine environment, biodiversity, protecting ecosystems, climate change, desertification, depletion of the ozone layer, transboundary movement of hazardous waste, chemical products and persistent organic pollutants. In the region in general most environmental multilateral agreements have been ratified. New legal and institutional regulations have been created to implement environmental policies, outstanding among which are national measures to eliminate production and consumption of stratospheric ozone depleting substances and measures relating to technology transfer in this field. These are having a significant impact.

On the other hand, many countries have high-level government bodies to coordinate sectoral policies on subjects of national interest. These range from water resources management, land regulation, urban management, reduction and treatment of solid waste, to sustainable forest administration. The seriousness of issues such as air or water pollution, land degradation or the proliferation of forest fires has made it essential to establish major control and preventive policies. Furthermore, the challenges and dilemmas of the relationship between international trade and the environment have prompted growing efforts in regional and sub-regional fora to integrate policies in this field. Although industry has been traditionally considered as antagonistic to environmental conservation, new technologies and approaches to production have made this concept outmoded. Industrial participation in the sustainable development process has been reflected by the use and development of innovative and more environment-friendly technologies. To strengthen this participation, companies have sought recognition for these innovations by means of voluntary certification mechanisms which, although their use continues to increase in the region, need to be extended to cover small and medium-sized enterprises. Alternative energy sources, such as bio-combustibles and wind or solar energy, are also beginning to be developed. Many of these initiatives receive multilateral, bilateral or private sector financing. Sustainable tourism is a good example of an industry with a low impact on the environment and with high economic and social benefits. New institutions and structures have been created to overcome existing environmental management difficulties, but it is unfortunate that many of these organisations have suffered from the worsening regional

economy and a reduction in state budgets: their faculties are often restricted, they lack resources and have few trained people to ensure compliance with standards. Therefore, as well as national financing, international cooperation and loans from multilateral organisations play an important part in the different policy responses. Financing comes from forgiving or cancelling the foreign debt, and also from global, regional, sub-regional, national and other combinations of funding sources. With a reduction in the flow of bilateral and multilateral cooperation, national financing, including fiscal resources, public budgets and private participation, is fundamental. In the past decade there has increased use has been made of such economic instruments as imposing taxes on the use of natural resources, paying for environmental services and providing benefits to local communities committed to efforts to protect the environment. These instruments raise income needed to improve services, administer natural resources and control projects and enterprises. New commitments such as those set out in the Monterrey Consensus revive the hope that official development aid could increase in the next few years, and lift international financial cooperation from its present low point. Public participation in environmental management is on the rise in Latin America and the Caribbean. Digital communication systems, particularly the Internet, have over the past decade been a major contributor to this. There has also been a notable growth in information and environmental monitoring systems on biodiversity, forestry and geological, hydrological and edaphic resources. Other initiatives include subjects such as compliance with environmental policies, citizen participation and strategies to disseminate information both digitally and over the Internet. In the private and public sectors, the search for responses to environmental problems is taking an increasingly preventive, participatory, multisectoral and interdisciplinary approach. Environmental training and education programmes have been considerably extended and carry great weight in the search for sustainable development. Education, from primary to postgraduate levels, is important because it helps to raise awareness and build capacities in the development of environmental policies. Governments, non-governmental organisations, the private, academic and scientific sectors and international and multilateral organisations also promote important actions in the field of non-formal education. The complexity of the environmental problem is now recognised, including the role of the different cultural sectors in solving it, as well as the strategic notion of the need to integrate it into the economy. Efforts are being made to encourage governments to provide more funds for research on environmental subjects, sometimes in collaboration with industry.

Multilateral environmental agreements and non-binding instruments Since the 1990s, and as a consequence of a global acceleration in environmental policy, an active part has been taken by Latin America and the Caribbean in a series of non-binding multilateral agreements and instruments in the fields of biodiversity, climate change, air pollution and desertification (UNEP, 2000). In recent years, important global agreements mainly concern biodiversity, pollution and sustainable development (UNEP, 2000). With respect to sustainability problems, particularly important is the adoption of specific global guidelines to deal with small island developing states’ environmental vulnerability. In the field of biodiversity, recent agreements reflect a growing regional concern about making proper use of biological wealth, including genetic resources, the production of food and marine ecosystems. Latin American and Caribbean countries possess enormous resources that interest companies and governments in industrialised countries. The Cartagena Agreement on Biosafety and the Rome Agreement on Phytogenetic Resources seek to regulate access to these resources by tropical and temperate countries, in contrast to the centuries-old free biodiversity exploitation. Another very relevant initiative in this respect is the creation of the Group of Like-Minded Megadiverse Countries, which has established common guidelines on access, use and conservation of genetic resources, as well as on respective intellectual property rights. Sub-regionally, there was a major strengthening of the Mesoamerican Biological Corridor, and Central American countries developed protocols to protect genetic and biochemical resources, as well as the knowledge indigenous people have of these resources. They also prepared a protocol to prevent biotechnological accidents and abuses, although it remains to be seen whether, in the context of large transnational interests, it is feasible to apply this in small countries. As to the environmental pollution problem, there is concern about its impact on crops and food as well as on the atmosphere and oceans. The region has played a leading part in this respect in several major initiatives: the most important measures include the Global Programme of Action for the Protection of the Marine Environment from Land-based Activities (GPA), the Stockholm agreement to control persistent organic pollutants and the Kyoto Protocol to limit the emission of greenhouse gases because of their impact on global warming. As the agreements require proper application, note should be taken of declarations made by judges from the region and the rest of the world at the Global

Symposium of Judges during the Johannesburg Summit, proposing concrete action be taken to improve environmental legislation and its implementation. In the region, the Forum of Ministers of the Environment of Latin America and the Caribbean continues to play a leadership role in adopting environmental policy decisions and instruments. Perhaps most significant in this respect is the adoption of the Latin America and Caribbean Initiative for Sustainable Development (ILAC), included in the Johannesburg Plan of Implementation as the path to follow towards regional sustainable development. In South America, important activity is taking place on three fronts: cooperation in Amazonia; Andean development; and trade between the principal southern cone countries.

Global agreements and initiatives The International Treaty on Phytogenetic Resources for Food and Agriculture was adopted, aimed at pollution related to agriculture. To control and reduce the use of hazardous chemical compounds, the Stockholm Convention on Persistent Organic Pollutants was signed. The Kyoto Protocol, which seeks to protect the atmosphere from global warming caused by human activities, was an important advance on the Framework Convention on Climate Change. Finally, during the Global Symposium of Judges in Johannesburg, a non-binding agreement was reached on promoting environmental legislation. To reduce degradation of marine ecosystems specifically affected by pollution from land sources, the Global Programme of Action for the Protection of the Marine Environment from Land-based Activities was adopted by more than 100 countries in November 1995, with UNEP as technical secretariat (PNUMA/ORPALC, 2003; see section on Coastal and marine areas in Chapter 2). With respect to the Caribbean, the most important international non-binding initiative has been the United Nations Global Conference on Sustainable Development of Small Island Developing States, held in Barbados in April and May 1994. The Barbados Declaration underlined the particular vulnerability of these states to natural and technological disasters, giving them a chance to influence international environmental action. To achieve sustainable development, the Barbados Action Programme approved at the conference was directed at integration strategies related to the environment, population and development of national and sectoral planning processes, so as to achieve sustainable development (UNEP, 2002b). Over the past eight years, this action plan has contributed to shaping many sub-regional and national initiatives in the Caribbean. The Cartagena Protocol on Biosafety of the Convention on Biological Diversity is a multilateral agreement ·

that has required extensive negotiations since 1996 until it was opened for signature by countries in January 2000 in Montreal, Canada (see section on Biodiversity in Chapter 2). This instrument regulates the transfer, handling and use of modified live organisms that might have an adverse effect on biodiversity; establishes an agreement on their export – basically seeds and micro-organisms – and includes a precautionary principle, according to which the environment must be protected before any damage occurs. To date it has been ratified by 11 countries in the region. The protocol entered into force in September 2003, after having been ratified by the 15th country in June (SCBS, 2003). In May 2001, the Stockholm Convention on Persistent Organic Pollutants, which is meant to protect human health and the environment against pernicious chemical products, was adopted (UNEP, 2003a - see the list of the twelve most dangerous persistent organic pollutants in the section on Environment and Human Health in Chapter 2). It will enter into force when it is ratified by 50 countries. By February 2003 most Latin American countries had signed the convention and 22 countries had ratified it. In November 2001, after years of intense negotiation, the new text was approved of the International Treaty on Phytogenetic Resources for Food and Agriculture of the United Nations Food and Agriculture Organization (FAO), defined in its Genetic Resources Commission. By July 2003, 14 Latin America and Caribbean countries had signed it, and three countries had accepted it or adhered to it. Ratification by 40 countries is needed before it enters into force (FAO, 2002a). The Kyoto Protocol is of particular relevance to the atmosphere. It has already been ratified by 24 Latin American countries and two have signed it. Developed countries have promised to reduce their greenhouse gas emissions to 95 per cent of the 1990 levels, at least, between 2008 and 2012. The Vienna Convention on the protection of the ozone layer, as well as the Montreal Protocol and its amendments, have had more success in the region where the 33 countries ratified the protocol, agreeing to freeze their consumption and production of chlorofluorocarbons at the average 19951997 levels from 1 July 1999. In February 2002, at the invitation of the Mexican government, the Group of Like-Minded Megadiverse Countries was established by Bolivia, Brazil, China, Colombia, Costa Rica, Ecuador, India, Indonesia, Kenya, Malaysia, Mexico, Peru, South Africa and Venezuela (see section on Biodiversity in Chapter 2). In the Cancun Declaration these countries –covering more than 70 per cent of global biodiversity – proposed to strengthen intergovernmental dialogue and cooperation on conservation and sustainable use of genetic resources (IUCN, 2002, SEMARNAT, 2002). The group has begun to contribute to international events such as the World

The Cuzco Declaration, signed in the same month, presents the conclusions and recommendations of the group on access to genetic resources, traditional knowledge and intellectual property rights.

An important non-binding agreement was produced at the Sustainable Development Summit held in Johannesburg, South Africa. Argentina, Brazil, Costa Rica, Cuba, Guyana, Mexico and Saint Lucia were among the countries participating in the declaration of the Global Symposium of Judges (August 2002). The declaration proposed that improvements be made in how the law is promoted and applied, in access to justice to solve

environmental controversies, in the application of environmental rights and in giving the public access to information. It also suggested strengthening international collaboration on education about environmental rights and on setting up a special committee composed of judges representative of geographic regions, judicial systems, international courts and tribunals (PNUMA, 2002a).

Regional and sub-regional agreements and initiatives On a regional and sub-regional scale, agreements and initiatives include two Mesoamerican projects (the Mesoamerican Biological Corridor and the PueblaPanama Plan), a Central American agreement on biodiversity (with two protocols, on access to genetic and biochemical resources and on biotechnological security), various initiatives in the Caribbean and three South American agreements on the environment (the Caracas Declaration on Cooperation in Amazon, the Andean Community Accord and guidelines and an environmental agreement for the Southern Common Market (MERCOSUR), as described below in this order. The Mesoamerican agreements are on the Mesoamerican Biological Corridor and the PueblaPanama Plan. As part of the sub-regional effort within the Central American Alliance for Sustainable Development (ALIDES), the Mesoamerican Biological Corridor initiative expects to reduce environmental problems that affect the quality of life in Mesoamerica, such as deforestation and fragmentation of the main protected areas. It is a unique multinational initiative of its type, endorsed by the presidents of the region since July 1997, which covers approximately 30 per cent of the Central American territory and the Maya forest area of Mexico, in protected, buffer and multiple-use areas. It hopes to protect present biodiversity, promote environmentallyfriendly production and reduce poverty and vulnerability (CCAD, 2003a - see the role of the corridor to prevent inbreeding in the section on Biodiversity in Chapter 2). In April 2000, a six-year, US$16 million project was begun, to consolidate the corridor in the eight Mesoamerican countries. The project, which is coordinated by the Regional Technical Office in Nicaragua, is financed with resources from the Global Environment Facility (GEF) and has links with technical and national commissions. It was endorsed by the Central American Commission on Environment and Development (CCAD) with the United Nations Development Programme (UNDP) and the United Nations Environment Programme (UNEP). Its activities include the generation and dissemination of information, exchange of experiences, technical assistance, the harmonization of environmental policies and legislation, sustainable management of resources, ecotourism and agroforestry management.

Chapter 3: Policy responses to environmental problems

In March 2001, the Puebla-Panama Plan (PPP) was unveiled. This is an official initiative of the Office of the Mexican President, with the Mexican states of Campeche, Chiapas, Guerrero, Oaxaca, Puebla, Quintana Roo, Tabasco, Veracruz and Yucatan. The plan has a General Coordinator’s Office and a Consultative Committee and promotes participation by Central American countries in joint activities. In the Joint Declaration of the Fifth Summit of the Tuxtla Mechanism for Dialogue and Concertation – known as the Merida Declaration – of 27 and 28 June 2002, Mesoamerican governments confirmed their conviction that human development is the objective of the Puebla-Panama Plan and recognised the development of regional projects by Ministers of Education, Culture and Health. They instructed the Executive Commission to include in the plan elements of agricultural and rural development with emphasis on: ·

food and nutritional security;

·

fisheries development and regulation;

·

strengthening and integrating regional markets and agro business;

·

technological innovation and development – with criteria of environmental, economic and social sustainability –, and

·

improving health, safety and agro health.

Finally, they stressed the advances achieved on infrastructure projects, electrical connections, road and telecommunications integration, as well as the creation of the Regional Commission of the Mesoamerican Tourism Initiative, and negotiations on free trade agreements, among other aspects (Cruickshak, 2001; SICE, 2002). At the Central American level, and also in the area of biodiversity, new protocols were approved. At the CCAD meeting, in San Salvador in May 2001, the Council of Ministers of the Environment approved two protocols to the Convention for Central American Biodiversity and Protected Areas: the Central American Protocol of Access to Genetic and Biochemical Resources and Associated Knowledge and the Central American Protocol on Modern Biotechnology Security. The first established a basic procedure and comprises a Central American access group. The second regulates the transfer, handling and safe use of modified live organisms by means of biotechnology. It seeks to protect sustainable use of biological diversity, bearing in mind risks to human health, and concentrating concretely on transboundary movements. However, these protocols need to be signed and ratified by Central American Ministers of Foreign Affairs and national assemblies (CCAD, 2003c). The Association of Caribbean States (ACS), whose members are the countries, states and territories in the Caribbean (including the Mesoamerican countries as well as Colombia, Venezuela, Guyana and Suriname) was established as a result of a convention adopted in 1994 in Cartagena de Indias, Colombia. In the convention’s preamble, thanks to the promotion of the ACS, the parties recognise the importance of the Caribbean Sea as a special sustainable development area. The Caribbean Community Secretariat (CARICOM) also has an active sustainable development programme, which focuses on the integration and coordination of the subregional sustainable development policy framework, providing institutional training and technical support to member states and formulating and implementing crosssectoral plans and programmes for local sustainable development. Specific work areas include: ·

marine resources;

·

managing disasters and emergencies;

·

planning human settlements and the environment;

·

climate change and meteorology, and

·

development of renewable energies and scientific and technological infrastructure.

One of the most important legal instruments in the Caribbean is the Convention for the Protection and

185

Development of the Marine Environment in the Wider Caribbean Region (Cartagena Convention) and its protocols (see section on Coastal and marine areas in Chapter 2). Also on a sub-regional scale, the Organization of Eastern Caribbean States (OECS) has actively promoted the sustainable development agenda. The Saint George’s Declaration of Principles for Sustainable Development, published by the OECS in April 2001, issues a new call for compliance with the sustainable development principles and commitments contained in the Rio Declaration and its Action Programme; in a similar manner, it underlines the importance of minimising the Caribbean’s inherent environmental vulnerability (UNEP, 2002b). In South America, there are three notable lines of action on the environment: cooperation in Amazonia, Andean coordination and the Southern Common Market (MERCOSUR). Concerning the first, the Fourth Meeting of Ministers of Foreign Affairs of signatory countries of the Amazon Cooperation Treaty (ACT) was held in April 2000. Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname and Venezuela signed the Caracas Declaration which, among other things, recognised the importance of this instrument in forging a common vision. That common development model will allow the region’s sustainable development activities to be guided and executed, particularly when it comes to the protection and sustainable use of forestry resources. As the declaration also recognised the opportunities that biodiversity and biotechnology offer for sustainable development, the countries agreed to: ·

coordinate positions on intellectual property and protect traditional knowledge about their biogenetic resources (sales of products derived from traditional medicines are over US$4,000 million annually; see section on Biodiversity in Chapter 2);

·

promote ratification of the Protocol on Biosafety;

·

establish synergies between the Convention on Biological Diversity and the United Nations Framework Convention on Climate Change and other international conventions on the environment and renewable natural resources.

This particular agreement was reached during the Eighth Ordinary Meeting of the Amazonia Environment Special Commission, held in Quito, Ecuador, in September 2001 (TCA, 2001). In the Andean sub-region, the Andean Community of Nations and its Andean Committee of Environmental Authorities have attempted to promote consensus and collaboration mechanisms in sustainable development areas. Recent achievements include the Carabobo Accord (June 2001) and the Guidelines for Environmental Management and Sustainable Development in the

As to regional cooperation mechanisms on the environment, the Forum of Ministers of the Environment of Latin America and the Caribbean continues to direct the formulation and adoption of decisions and instruments on environmental management (PNUMA, 2002b). At its 13th meeting, held in Rio de Janeiro in October 2001, the Forum approved a Regional Strategic Action Plan for 2002-2005. Its strategies are to integrate the environment into economic and social development processes, sustainable use of natural resources and ecosystems, urban environmental management, strengthening the regional environmental agenda and assessing environmental sustainability. Within the framework of the Global Summit on Sustainable Development, the Forum held an extraordinary meeting on 31 August 2002 in Johannesburg, where it approved the Latin America and Caribbean Initiative for Sustainable Development (ILAC), which established operational directives to move the region further towards sustainable development. These directives reiterate the positions adopted at the International Conference on the Environment and Development (Rio de Janeiro, 1992) which are: ·

to promote the entry into force of the Kyoto Protocol;

·

demand that developed countries comply with assistance targets of 0.7 per cent of their GDP and with the commitments of the Doha Declaration and the Monterrey Consensus;

·

recognise the precautionary principle as a key element in environmental policy;

·

give priority to the Barbados Action Plan; and

·

187

strengthen initiatives such as Local Sustainable Development Councils and the formulation of local and national Programmes 21 The initiative defines priority areas and goals:

·

eradication of poverty;

·

introduction of the environment into economic and social processes;

·

strengthening of technical and vocational training institutions;

·

promotion of human resources development;

·

encouragement of the establishment of micro-enterprises;

·

the giving of real power to civil society organisations;

·

promotion of economic diversification;

·

promotion of regional cooperation and collaboration to increase access to international markets;

·

definition of economic, social and environmental vulnerability;

·

sustainable management of water resources;

·

sustainable generation of energy and more use of renewable sources;

·

protected areas management for sustainable use of biodiversity;

·

adaptation to the effect of climate change;

·

sustainable management of urban and rural areas;

·

promotion of scientific and technological innovation;

·

strengthening of research and development institutions, and

·

the identification of more funding sources (UNEP/ ROLAC, 2002b).

The ILAC was included as part of the Implementation Plan of the World Summit on Sustainable Development in Johannesburg.

ble and be very critical when judging whether it would be feasible to apply them, considering local economic needs and pressure from foreign interests. It is therefore essential to harmonise commitments of trade and environmental agreements, so that liberalisation of trade does not result in more environmental deterioration. The region must continue its outstanding participation in the struggle against global warming and pollution, as it did with the Stockholm and Kyoto agreements. Finally, the concrete actions outlined at the Johannesburg Summit on environmental legislation and its implementation must be supported.

Environmental policies Most countries have a national environmental policy instrument that serves as a basis to coordinate sectoral policies on subjects as diverse as water resource management, land regulation, urban management, reduction and treatment of solid waste and forestry administration. Among them, those that have been given high priority on government agendas include the insertion of carbon in the global market and the promotion of cleaner production. Priority has also been given to certain serious natural events: for example, governments have been quick to establish policies to control, combat and prevent forest fires. These are subjects that require integration and some incipient efforts are starting to become evident in the areas of trade and the environment Sub-regional bodies such as the Central American Commission on Environment and Development (CCAD), the Caribbean Community (CARICOM), the Andean Community of Nations (CAN), the Association of Caribbean States (ACS), the Amazon Cooperation Treaty (ACT) and the Southern Common Market (MERCOSUR), among others, have made efforts to integrate by holding meetings and preparing plans and reports. To coordinate sectoral environmental policies with more general policies, many countries use economic instruments – still incipient in the region – as a complement to direct regulation tools. Both the instruments and the economic and environmental policies are often interlinked. In the context of the recent adverse economic situation, particularly in the fiscal area (see section on Socioeconomic trends in Chapter 2), environmental policies have lost their prime position on government agendas, especially when it comes to such matters as the economy and poverty. Nevertheless, Latin America and Caribbean countries have been active in preparing and promulgating environmental policies, especially of a sectoral nature. The subject of water resources has become particularly relevant, as drinking water supply diminishes and

·

Chapter 3: Policy responses to environmental problems

pollution increases, resulting in more competition for its different uses. Also of fundamental importance are drainage systems and treatment of household and industrial sewage. Predominance is given to the identification of decentralised administration systems as well as to private sector participation. Economic instruments have been used to improve water services and quality (Fernández-Busto, 2001). In some countries there is a tendency to consider water basins as basic environmental planning and management units, integrating different policy perspectives – land regulation, deforestation, cleaner production, proper soil use – to promote sustainable development and eliminate pollution (ECLAC and UNEP, 2001). When it comes to urban centres, cities continue to grow, although more slowly than in past decades. The degree and growth of urbanisation varies considerably between countries and within them. In spite of persistent weaknesses in instruments to plan and manage human settlements – in part because of region’s early and rapid urbanisation – countries have more experience and technical capacity to face the new challenges. There is also more awareness of the multidimensional and farreaching nature of land, urban and housing policies. At the regional level, the Regional Meeting of Ministers and Lead Authorities of the Housing and Urban Sector of Latin America and the Caribbean (MINURVI) plays an essential role in strengthening housing policies, while the 1995 Action Plan for the Latin America and Caribbean Region continues to be the reference instrument for countries to apply joint action and make individual efforts. The diversity of urban centres makes it necessary to abandon purely sectoral approaches. Coordination is also required among central and decentralised levels of government to compensate for development imbalances, and to make more coherent efforts to organise activities and investments (CEPAL, ONU-Hábitat, 2000). It is becoming more relevant to develop alternative sources of energy, less polluting and, therefore, more environmentally friendly, as well as energy-saving programmes and incentives . These are usually in the form of tax exemptions for more efficient energy producing and consumption equipment. In industry and commercial enterprises, efforts are concentrated on seeking the financing needed for technological change. Another trend is towards the integration of the international carbon market, promoting internal carbon markets, and developing alternative fuels – as in Argentina and Brazil – that reduce emissions from fixed and mobile sources (Fernández-Busto, 2001). When it comes to forests, the region in general has recognised that deforestation is one of the most serious environmental problems and that action is vital to prevent, control and combat forest fires. In 1998 at least 9.2 million hectares of forests were affected by fires in Latin America. This has forced the region to prepare and

Environment Outlook

implement more preventive, monitoring and fire-fighting policies and tools. The high cost of fires and lack of equipment and human resources obliges developing countries to seek international cooperation and enter into agreements on the use of satellites. Costa Rica, Honduras and Mexico have well -organised fire-fighting brigades. Mexico has also improved its tools and monitoring maps, as well as its forecasting capacity.

Guatemala has received considerable international help because of the interest in protecting the Mayan ruins at Peten. The Ministry of the Environment and Natural Resources of Venezuela uses economic preventive and control incentives.

The evolution of PROALCOHOL in Brazil Brazil has the only large-scale programme that has successfully replaced fossil fuels by a form of renewable energy, reducing greenhouse gas emissions. PROALCOHOL (the programme to produce anhydrous alcohol) was the Brazilian governments' response to the oil crisis that started in 1972. The programme began in 1975 (decree No. 76,593) and was designed to increase sugar cane production, alcohol from which can be a substitute for petrol. Its objective was two-fold: to provide fuel for specially-designed motor vehicles and to add alcohol to petrol in normal vehicles, to make them less polluting. At the end of the 1970s the programme was expanded to promote the cultivation of new types of cane, an agroindustrial plan and the development of a fleet of vehicles to use the mixture of alcohol and petrol. More than half of sugar production is now concentrated in Sao Paulo. Incentives were offered for the construction and operation of new distilleries, and for mechanisms to distribute the new fuel to gas stations all over the country. The government made its use mandatory in all official vehicles, offered tax incentives to producers and consumers and, to build a market for it, fixed a lower price for it than for petrol. As a result of these measures, alcohol production increased from half a million cubic metres annually in 1979 to 15 million in 1987. The first vehicles to use alcohol were produced in 1979 and, after overcoming technical problems, sales increased exponentially until they reached 92 per cent of the total number of vehicles in the 1980s, and 50 per cent in 1990 (some five million units). In 1989, availability of alcohol dropped and consumers lost confidence. This led to a constant lowering of consumption so that the percentage of vehicles using anhydrous alcohol fell to 30 in 1993, 12 per cent in 1994 and later to one per cent. Only 10,000 new alcohol-propelled vehicles were sold in 2000. The volume of alcohol sold was barely 5.1 million cubic metres in that year (although the cane industry earned US$4,000 million, and sales of alcohol reached US$2,000 million). This drop was caused by changes in inflation control policies, a drop in oil prices and a loss of interest on the part of the authorities. Although the PROALCOHOL programme has never been officially closed, since 1998 the government has progressively reduced subsidies to the programme and now prices are governed by free market laws. It has been estimated that to maintain the general profitability of the alcohol market, sales of vehicles would have to reach 200,000 units annually (10 per cent of the total). The new monetary policies of 1999, among other factors, have pushed a resurgence of the cane industry for other purposes, with the risk that some producers will change from alcohol to sugar and perhaps lead to the repetition of the 1989 situation. However, compared to petrol, the price of alcohol is still quite competitive and the country has saved more than US$20,000 million in imports of oil and its derivatives. Estimates indicate that it has generated more than a million direct and indirect jobs. In addition, it has contributed to land revaluation and air quality improvement. Electric energy generation from sugar cane residues is also an important option. Among the short-term challenges for the programme's survival is how to redirect the sugar industry to other uses, the lack of coordination of policies and activities of different government agencies Eletrobras, Petrobras, Ministry of Agriculture, the National Petroleum Agency -- the absence of laws or policies to guarantee the continuous and longterm supply of alcohol to consumers, as well as the transition to a free market. To guarantee the permanence of PROALCOHOL a strategic programme from an environmental point of view - the Brazilian government must encourage motor vehicle manufacturers and sugar cane producers to take measures to reverse the decreasing trend in the use of alcohol.

National biodiversity strategies (and their action plans) prepared within the framework of the Convention on Biodiversity, are the prevalent policy instruments.

the National Fire Management Programme (PREVFOGO). In Chile the government has made private timber companies responsible for fighting fires on their own property. Forestry laws in Mexico and Costa Rica prohibit land-use change and punish those caught setting fires in forests (Cochrane, 2002), At the sub-regional level, coordinated efforts have been made to control forest fires. The CCAD, with the cooperation of different international agencies, held a Regional Workshop to Develop a Strategic Regional Plan to Manage Forest Fires and Pests, in Siguatepeque, Honduras, in August 2002. The plan, the adoption of which the Central American Council on Forests and Protected Areas recommended to the CCAD Council of Ministers, includes actions on management, prevention, control and restoration, as well as general guidelines on strengthening base organisations and planning land use and prevention based on social demands. It is hoped to set up a CCAD regional working group, with a regional attention centre in which Mexico would be included (CCAD, 2002). Regarding biodiversity, the use of resources is influenced by other sectoral policies. Several governments – particularly in sub-regional fora such as CAN, CCAD and MERCOSUR – have made efforts to integrate their policies on trade and the environment. These include aspects such as intellectual property rights, the rights of indigenous people and local communities, access to genetic and biochemical resources, and benefit sharing from having access to and using genetic resources, biotechnology and, to some extent, biosecurity – particularly relating to transboundary movements of modified live organisms.

Chapter 3: Policy responses to environmental problems

Policies on protected areas increasingly concentrate on consolidating systems, areas and institutions responsible for their protection, as well as their sustainable management, and less on creating new areas (the trend is also to create much smaller areas than in earlier years; see section on Biodiversity in Chapter 2). In relation to biodiversity, other subjects recently dealt with have caused quite a lot of controversy among different sectors of society. There is no agreement on possible risks to society from genetically-modified crops (UNEP, 2002a). Paraguay issued the first resolutions that open areas to transgenetic material testing (Zavala, 2002). The development of local governments, decentralisation and citizen participation is very important. Local and municipal governments are in a privileged position when it comes to helping to improve the quality of life so the subject of decentralisation occupies an important place in national policies. These governments have more resources than they had a decade ago, although distribution remains very unequal. They also encourage competition for greater access to more abundant resources to meet the needs of both traditional services (health and education) and new obligations (environment, employment and citizen security) (CEPAL, 2002). Municipalities have been fundamental in developing local economies, from decentralisation they have acquired the responsibility for providing new services or managing natural resources – in particular the integrated management of water resources and they have re-evaluated their role in environment management. In other spheres, decentralisation processes have been directed towards communities, as in the joint management of protected areas in countries such as Saint Vincent and the Grenadines, Jamaica, Trinidad and Tobago, El Salvador, Belize and Guatemala by the significant participation of non-governmental organisations (UNEP, 2000). From the moment they are prepared, policies seek broad participation by different sectors, including state bodies, non-governmental organizations and the private sector. They establish the obligation of openly debating the implementation of large projects, such as the construction of hydroelectric dams, the establishment of protected areas, the opening of mining projects or the building of highway infrastructure. There are both formal and informal participation channels, but they should all lead to the establishment of formal mechanisms such as technical consultation groups, commissions, and hearings. There is still much to be done to manage hazardous and industrial waste, review legal and institutional

Trade rade and the environment - at the crossroads Net global trade grows day by day, not only because the population increases but because more markets are being opened, giving consumers access to more and more varied goods. This growth in trade inevitably increases pressure on natural resources and, therefore, environmental deterioration worsens. The sustainable development model, as a response to this deterioration, suggests that more goods may be produced without spoiling natural resources for future generations; it would be hard to find a government or an industry that does not publicly support this model. More important still, sustainable development is included almost routinely in statements about proposed action by the World Trade Organization, the Organization for Economic Cooperation and Development, the North American Free Trade Agreement and the proposed Free Trade Agreement of the Americas. However, when actual accomplishments are reviewed, the reality is generally concerned with the dilemma and not with its solution. The origin of these failures is usually the same: Latin America and Caribbean countries are seriously affected by the burden of their foreign debt and their governments see a strong dose of foreign investment as the solution, represented more by large transnational companies than by any other source. Costa Rica is frequently quoted as an example, as it is now applying the still little-appreciated model of working with resources that have a low environmental impact, such as tourism and microcircuit assembly. Nevertheless, for 30 years it exported cheap meat produced by deforesting large areas (including some of the last remnants of the continent's dry forests) and, although it was a relatively efficient production (in the sense that while the grassland areas doubled meat exports increased five-fold), it proved to be unsustainable ecologically, socially and economically. However, experiences such as those of Costa Rica took place in a relatively regulated market environment. The crucial question now is what will be the relation between trade and the environment in a free trade area of any of the types proposed. To preserve the principle of sustainable development, some of the actions proposed by these types of treaties include the following: · · · ·

Follow-up on environmental standards suitable for developed countries; Participation in the agreement by all interested countries; Transparency in decision making, and Inclusion of clauses that specifically refer to the environment.

Critics complain that, in practice, almost all these actions are absent from free trade and similar agreements. Environmental standards suitable for developed countries are often difficult to apply in developing countries due to economic and, occasionally, also technological limitations. A well-known example is the failed attempt to control mercury pollution in gold mines in Amazon. Participation in the agreement by all interested countries is not ensured, as has been demonstrated by how the World Trade Organization functions, where not all members participate in the decisions. Transparency in decision making is also indisputable: in the case of the proposed Free Trade Agreement of the Americas, eight years passed before possible inclusions were made public and civil society was invited to make suggestions. These agreements are designed principally to protect investors, and so establishment of clauses specifically referring to the environment (although this may seem the most obvious and demonstrable factor) is, nevertheless, their Achilles heel. For example, the North American Free Trade Agreement includes a clause that allows any investor to sue a government in any civil court for “financial damage” suffered, independently of the cause. Cases like that of the Metalclad company against Mexico show that this clause might be a means of environmental protection and that the court will side with the investor. In practice, these clauses neutralise the sustainable development model and oblige developing countries to capitulate, because they cannot risk having to pay many millions of dollars in damages to large foreign companies. To get over the dilemma and reach a sustainable development balance requires open agreements, equal participation by developing and developed countries (including the private or civil sector), realistic environmental standards and the elimination of clauses that protect investors even in cases that are contrary to environmental common sense.

frameworks to promote technological change, develop the environmental market and create fiscal incentives to promote environmental investments to be financed by development banks (Fernández-Busto, 2001). Other challenges and voids are seen in still embryonic actions to combat desertification, sustainable soil management, urban management, and marine biodiversity management and conservation.

Principal challenges The region must adopt integrated environmental policies, coordinating government agencies, productive sectors, non-governmental organisations, and international agencies. Local initiatives and decentralisation should be promoted to manage basic resources such as water. Environmental policies must permeate economic and social policies, promoting the use by companies of non-polluting technologies and risk management and education methods, and they should be reminded of their social responsibilities. Equally, mitigation and preventive policies must include such diverse items as managing water basins and coasts, protecting marine species and controlling degradation of marine habitats. Water supply and quality must be improved, organic and chemical pollutants eliminated, vulnerability to disasters reduced, deforestation halted and more efficient energy sources developed. Finally, soil conservation and organic agriculture must be encouraged, habitat loss stopped, fragmentation of ecosystems corrected, and illegal trade in endangered species and the introduction of exotic species prevented.

Policy implementation and impacts Policy responses are reflected in new legal and institutional regulations, which have had an impact in areas that include voluntary certification, as well as alternative sources of energy and sustainable tourism. Certification continues intensifying in the region as a voluntary market positioning mechanism and to increase competition and productivity. With the support of state programmes or private initiatives, industries and agro industries of all sizes seek to certify their processes, products or crops, by meeting a series of environmental and social requirements. The standardisation processes of some multinational companies often exceed national norms. Progress is also being made in developing alternative energy sources, especially on projects on biochemical development in South America, wind energy in Costa Rica, and solar energy in the Caribbean. Furthermore, a number of cleaner production centres and other successful projects have been established; efforts by the

public, academic and private (especially industrial) sectors to find environmental management technological innovations and improvements have contributed to these. Such initiatives have also been supported by international and regional organisations, and have received multilateral, bilateral and private sector financing. In December 1988 the United Nations General Assembly named 2002 as International Ecotourism Year. A series of activities and meetings were held in the region. As a result of productive dialogue, tourism and environmental authorities integrated their policies. Representatives of 24 countries in Latin America and the Caribbean and from Spain attended the first Latin American Tourism and Environmental Summit in the Galapagos Islands, Ecuador, in May 2002. The Summit produced the Galapagos Declaration, signed by representatives of participating ministries of Tourism and the Environment. The subjects considered included policies, norms and strategies; conservation; development; social responsibility; and research; as well as their respective instruments. The promotion of tourism in the region was at the heart of the declaration, which also covered criteria of sustainability and participation by local communities in decision-making.

Regulatory structures and national institutions Global and regional multilateral environmental agreements have been reached, and sectoral policies developed that promote reform of national legal regulations. This has resulted in the promulgation of many laws, decrees and other environmental standards (Brañes, 2001). This institutional renovation or innovation process has been channelled in three directions: the creation of new structures; the definition of coordinating bodies; and the allocation of new functions to existing institutions (Brañes, 2001). These institutions usually have very broad remits, often with limited resources and trained personnel, so controls and compliance with standards are difficult to implement. This makes it important to change institutions and, in some cases, even the laws themselves. Institutional modifications began in the mid-1990s, and have been consolidated over the past three years. In Mexico, for example, the National Commission on Protected Areas and the National Forestry Commission were created, both as decentralised bodies. The Fisheries Institute is now under the Ministry of Agriculture, Livestock, Rural Development, Fisheries and Food. The National Multisectoral Integration Certification Council was also established (Gutiérrez, 2002). In Guatemala, the new Ministry of the Environment and Natural Resources replaced the National Protected Areas Commission and the National Environment Commission was abolished. The National Forest Institute continues to exist

Environment Outlook

but as an autonomous body, not as part of the Ministry. Paraguay is among the countries with a Ministry of the Environment, established by Law No. 1561 of 24 July 2000 (Zavala, 2002). By Supreme Decree No. 26755 of 15 August 2002, Bolivia restructured the organisation and responsibilities of the Ministry of Sustainable Development and Planning, which now has three sub-ministries, including one on the Environment and Natural Resources (Justiniano, 1996). In the Caribbean, most countries have issued specific laws to establish environmental institutions (ministries, commissions, councils) or have included the environment in already-existing dependencies (ministries of tourism, health and housing). Legislation adopted by Caribbean countries within the framework of the Earth Summit, includes: ·

the National Law on Conservation and Environmental Protection of 1987 (and its amendment of 1996) in Saint Kitts and Nevis;

·

the National Authority Law on Conservation of Natural Resources of 1991 in Jamaica;

·

the Environmental Protection Law of 1992 in Belize (amended in 1998);

·

the Environmental Management Law of 1995 in Trinidad and Tobago;

·

the Environmental Protection Law of 1996 in Guyana, and

·

the National Authority Conservation Law of 1999 in Saint Lucia (UNEP, 2002b).

Legal changes, on the other hand, are of three basic types, sometimes combined. They concern: ·

sectoral laws,

·

framework laws and

·

laws following environmental multilateral agreements.

Examples of fundamentally sectoral laws or legal dispositions can be found in Mexico, Guatemala, Barbados, Peru, Chile and Argentina. In Mexico the General Wildlife Law – which repeals the earlier Hunting Law — was approved on 3 July 2000, its reform was approved on 10 January 2002, and the regulation on natural protected areas on 30 November 2000. The General Forestry Law and the Biosecurity Law are now being studied (Gutiérrez, 2002). In Guatemala, Ministerial Agreement No. 1173-99 regulates and promotes organic or ecological production (Rojas, O.E., 2002). In the Caribbean, various sectoral laws have been issued, such as the Control of Marine Pollution Law of 1988 in Barbados (UNEP, 2002b). In Peru a new Forestry and Wildlife Law, No. 27308 of 16 July 2000, and

193

a Solid Waste Law, No. 7314 of 10 July 2000, were approved (Solano, 2002). In Chile, after the National Environment Commission (CONAMA) was restructured, a new policy was established concerning natural resources, which presumably will lead to modifications in legislation (Maldonado, 2002). In Argentina, Resolution 1076 of 8 August 2001 was published to support the National Biocombustible Programme of the Ministry of Sustainable Development and Environmental Policy; the National Alternative Energies and Fuels Programme was created by disposition No. 166/01 of 16 October 2001; and the Clean Development Mechanism Office of Argentina was established by disposition No. 167/01 also of 16 October 2001, to review projects within the framework of the Kyoto Protocol, by (SADSA, 2002). Framework laws have been developed fundamentally on the regulation and overall management of water resources (see section on Freshwater in Chapter Two). This is in response to the sectoral approach limitations (centred on a single use of water, for household or industrial consumption, irrigation or electricity generation) and the proliferation of sectoral laws and plans, unconnected or obsolete. A common feature of framework laws on water resources is designating the water basin as an administrative unit, decentralizing the state’s functions and responsibilities towards local governments, using economic instruments – such as payment for environmental services – and including the private sector and users in water management. These new directions have different motivations, but they influence policies to promote citizen and private sector participation, decentralizing policies, achieving an efficient drinking water service, finding solutions to the rising pollution and more competition between the many uses of the resource, sharing a transboundary basin, as well as conventions and international events, for example the World Water Forum (Jouravlev, 2001). The third case of a legal initiative concerns laws approved to comply with commitments acquired through environmental multilateral agreements. For example, in Nicaragua consultation was undertaken to raise awareness of and improve a draft Biological Diversity Law (MARENA, 2001). In Venezuela a Biological Diversity Law was approved in 1999; in Peru, in the same year, a law was approved to prevent risks arising from biotechnology and, in 2002, a law that established the regime to protect native people’s collective knowledge on biological resources.

Effective implementation Countries in Latin America and the Caribbean have made efforts to improve the effect of their environmental sectoral policies. More recent standards that are

better suited to the sustainable use of resources have been adopted, although there still remains the question of effective implementation with respect to both biodiversity and forestry. In spite of vast institutional development experience, the implementation of environmental policies, laws and regulations has been

conflictive because of the absence of or weak coordination with other public agencies, overlapping of responsibilities between sectoral and environmental institutions, budgetary restrictions and a lack of technical training, of human resources or of political will (UNEP, 2000).

Chapter 3: Policy responses to environmental problems

Environment Outlook

For example, in the area of energy, different initiatives have been developed, such as the National Electrical Energy Conservation Programme (PROCEL) in Brazil, the Energy Saving Programme in Cuba, the National Commission to Save Energy (CONAE) and the Electric Energy Saving Trust Fund (FIDE) in Mexico, and the Energy Saving Programme (PAE) in Peru. However, some initiatives have still not been incorporated into energy policies, principally because of a lack of political will, and on occasion either because they are developed in isolation or are marginalized. In this respect, the project Promotion of Efficient Use of Energy in Latin America executed by Economic Commission for Latin America and the Caribbean (ECLAC) and the European Commission SYNERGY programme has proposed, after making an analysis in various countries, a series of specific legal and institutional reforms: draft laws in Argentina, Colombia and Peru. The analysis concluded that although most Latin American countries have energy efficiency and, to a lesser extent, renewable energy programmes they lack strong legal, regulatory and institutional frameworks, effective coordination between the public and private sectors and adequate financing mechanisms. They have thus met with little or no success. In the field of integration of energy markets, MERCOSUR has made the greatest advances as to binational hydroelectric and natural gas projects (Lutz, 2001).

Principal challenges When it comes to the impact and application of environmental policies, multilateral and regional agreements must be ratified, national legislation must be adjusted and missing standards added. Mechanisms need to be set up to take into account still unrecognised environmental services. Legislation must also include new technical and technological standards, any reform or creation of which must be carried out through the widest possible participatory processes. Another challenge is to put into practice long-term effective, self-sustainable and economically efficient instruments, particularly on forestry and water policies. Forest management must benefit local communities; governments need to assist communities and enterprises with environmental management and technological innovation. The policy framework must integrate industrial, technological, foreign trade and business promotion policies, and resources should be quickly and simply available.

Economic instruments The use of economic instruments in the Latin American and Caribbean region remains gradual and isolated, but it is being increasingly extended to environmental management and in ways that are becoming more varied. The following section is based on the study prepared by Jean Acquatella for ECLAC (Acquatella, 2001).

195

The challenge confronting authorities responsible for environmental management consists of putting into practice instruments that are effective, self-financing and economically efficient over the long term. This imposes a need to be innovative when faced with traditional instruments and fiscal restrictions in countries in Latin America and the Caribbean. Charges, taxes or tariffs have been used to promote the use of cleaner technologies or environmental recovery activities. Use has also been made of informal regulations – rather than true instruments – as incentives for companies to report on their environmental performance, enhance their reputation, make them more attractive than their competitors or increase their value in the capital markets. It should be borne in mind that in most countries in Latin America and the Caribbean there remain incentives or subsidies in place that are potentially harmful, such as tax exemptions for fertilisers and pesticides, which encourage the use of these pollutants (ECLAC and UNEP, 2001). Incorporating self-financing economic instruments allows greater flexibility and the opportunity to create funds intended specifically to finance management. However, they are still rarely applied in the region and have mostly been used to complement direct regulatory instruments, of much broader application, such as environmental standards or agreements between authorities and private sectors. Their success depends on environmental and fiscal authorities working together; it also depends on the control and follow-up capacity to ensure compliance with environmental regulations, still beyond the reach of many developing countries. While the extended use of such instruments would contribute to improving environmental management, the authorities in many countries encounter obstacles (at the legal or coordination level, or of the necessary institutional capacity) which can only be overcome with strong political support. In Mesoamerica, novel instruments have been applied in Mexico (forests, water), Guatemala (reserves administered by ethnic groups) and Costa Rica (environmental services in general). In Mexico two large forestry incentive programmes have been developed: the Forestry Development Programme (PRODEFOR) and the Programme to Develop Commercial Forestry Plantations (PRODEPLAN). Together they were able to cover 600,000 hectares, benefiting less developed producers, and generating 18,000 direct and 15,000 indirect jobs. Just as in Brazil and Colombia, in Mexico there is a charge for dumping pollutants and it usually costs more than building the devices to comply with environmental standards. However, as control and collection are inefficient, the charges have not met the proposed objectives so that legislation on income, expenses and income tax has recently been modified to include new fiscal measures such as total exemptions and depreciation of up to 100 per cent on anti-pollution equipment (Gutiérrez, 2002).

Categories of economic instruments for environmental management Direct control

Regulations and sanctions

Market orientation Charges, taxes and tariffs Incentive and financing

Standards: The government regulates the type and amount of pollution from individual sources/agents. Compliance is monitored and penalties imposed (fines, closures and prison) for failure to comply. Includes zoning measures, technological regulations, quantity regulations and operating licences or permits.

Charges for effluents or use: The government charges polluting sources or individual users according to the amount of pollution or the use of the resource and the nature of the effluent's destination. The charge is high enough to be an incentive to reduce the impact.

Standards or maximum pollution levels. Licensing polluting economic activities. Restrictions on land use. Regulating the impact of building roads, pipelines, ports and communication cables. Environmental rules for urban transport Fines for oil spills in ports and on land. Prohibition of unacceptable material for collection by municipal garbage collection services. Water use quotas.

Charges per volume of excess pollution. Environmental taxes. Royalties and financial compensation for exploiting natural resources. Performance vouchers deposited to guarantee compliance with building standards. Taxes on different forms of transport. Tax incentives on re-use and re-cycling of materials (e.g. tyres and batteries. Charges on effluents to reduce downstream treatment requirements. Tariffs on solid waste collection. Water use charges. Tax incentives for investments in clean technologies. Financing environmental investments through special funds.

Final demand intervention (informal regulation)

Legislation Responsability for damages

Transferable permits: The government establishes a transferable permits system for polluting or using resources, auctions or distributes the permits and monitors compliance. Polluting sources or users of resources may freely transfer their assigned permits at freely fluctuating market prices.

Performance classification: The government supports a performance labelling or classification programme that requires producers to provide environmental information about their products, destinations or final use. Adoption of voluntary certification based on performance such as ISO 14000 (for example, zero pollutants discharge, mitigation plans, using pollution prevention technology, waste re-use and re-cycling). Ecological labelling for “environmentally ideal” products.

Strict environmental responsibility legislation: The law requires that the polluter or user of the resource pay for damages caused to third parties. The affected parties receive compensation through litigation and the legal system.

Include “environmental values” in construction expropriation prices. Well designed property rights on resources that might be affected by urban development (forests, land, fishing zones). Deposit-reimbursement systems for solid and hazardous waste. Transferable permits for water use rights, and to emit pollutants into the air and water.

Legislation requiring producers to publish data on their solid, liquid and toxic waste production. Publish list of polluting companies. Labelling products of (eco-labels) harmful materials (e.g. detergent phosphates). Education on re-use and recycling.

Damage compensation. Responsibility of management of the negligent company and of environmental authorities. Long-term performance vouchers deposited to guarantee against potential infrastructure construction risks. “Zero net impact” requirements for cables, pipelines right of way for public electricity, water or other services.

Creating markets

Tax incentives and financial facilities: The government seeks to promote investments in technology and cleaner production, reforestation and other positively activities. Financial facilities for environmental investments of SMEs and other priority sectors.

Environment Outlook

In Guatemala, the objective of the protected areas forestry concession system is for the indigenous communities to design their own management plans, to protect against illegal felling, forest fires and other threats. Illegal felling and forest fires have been reduced and sustainable timber production increased; however, the market is still underdeveloped and transition has been slow. A positive aspect that stands out is the strong institutional support given to this system.

term sustainability; the forest is no longer thought of solely as a source of timber; but is now considered a provider of environmental services,. The success has been obvious on the 252,584 hectares that received payments between 1997 and 2000 (around five per cent of the total territory, and 11 per cent of forest territory). Earlier incentive programmes lasted for 24 years and covered only slightly more than 150,000 hectares (Orozco and Ruiz, 2002).

Another complementary programme is that of Forestry Incentives (PINFOR), in which the state pays a sum of money to the proprietor per hectare reforested. While the annual number of hectares reforested has grown from 1,273 to 5,300, the area remains small. A sub-system of private reserves has also been created better to define property rights over wildlife conservation areas. It is hoped to protect them from being converted to agricultural uses, undervalued as sources of credit or declared vacant land with the risk of invasions (Acquatella, 2001). It took three months for the registration of the first private protected areas and the network of proprietors of private reserves already has 30 members and continues to grow (Rojas, L., 2002).

The Caribbean has alternative energy experience. Barbados exempted solar energy water heaters from tax to encourage their installation. This has been a successful initiative and has created 100 jobs, in part due to the publicity that resulted when the Prime Minster installed one in his own residence, saving 60 per cent of propane gas consumption.

In Costa Rica, the policy of payment for environmental services (PSA) continues to strengthen, involving public and private companies whose principal requirement is water (to generate energy, meet municipal or household demand, or produce drinks) and that pay to protect the aquifers from which it is drawn (see also section on Freshwater in Chapter 2). The Ecomarket project, designed to strengthen the PSA, was put into operation in 2001 with a soft loan of US$32 million and a donation of US$8 million from the World Bank and resources from the Global Environment Facility. The project’s objective is to consolidate the National Conservation Areas System and the National Forest Financing Fund by providing technical and financial support on reforestation and forest protection and management activities all over the country, including priority areas of the Mesoamerican Biological Corridor (Wo Ching, 2001). The 2001 Law on Tax Simplification and Efficiency establishes that 3.5 per cent of the fuel tax will be used to finance the state Payment for Environmental Services Programme (PPSA) and will be transferred by the Ministry of Finance to the National Forest Financing Fund (FONAFIFO). In addition, FONAFIO has negotiated other agreements and national donations to provide it with additional resources. The Costa Rican Joint Implementation Office has played a leading role in gaining access to international resources. The Costa Rican PPSA is unique in Latin America and the Caribbean and, for almost four decades, has shaped the country’s efforts to protect biodiversity. Its development introduced institutional, financial and legal reforms and brought a series of technical reforms, all of which confirms its feasibility and heralds its long-

197

There are also important examples in South America, in Colombia and Brazil (water), Venezuela (industrial waste), and Paraguay (forestry sector)). Colombia has made the most advances in this respect, with application over three decades of the repayment rate charged for discharging sewage. Initially, they were meant to be used more as tax collecting instruments, based on the cost of eliminating discharges or controlling the damage they caused. Now they have become a true economic instrument that includes the cost of pollution in economic activity costs. The environmental authorities fix minimum tariffs, increased every six to 12 twelve months according to the region, until the established decontamination goal is reached. This is an incentive to those responsible for discharges to reduce them by using options that cost less than the tax. The income collected is placed in a fund which finances decontamination projects in the basin. The result has been a significant reduction of pollutants in the Negro (Antioquia) River after only one year of implementation (CEPAL, 2000). A volume-based system of tariffs on industrial waste has been implemented in the Caracas, Venezuela, metropolitan area, with the coordination of all the city’s municipalities. The system, with half-yearly tariff adjustments, covers the cost of operating the dump and

has encouraged companies to reduce their amount of waste. In 2001 Paraguay established forest certification criteria based on those of the Forest Stewardship Council, and introduced organic agricultural certification (Zavala, 2002). In the state of Sao Paulo in Brazil, the public health company charges a tariff for dumping effluents into the drainage network according to volume and amount of pollutants. The cost of the drainage network’s treatment plant has been recovered, but the volume of water consumed and the coefficient of the effluent’s polluting content remain the same. The state of Ceará has established differential payments for agricultural, industrial or urban water use. The generation of income in the integrated management system has been stabilised and the demand for water for industrial and in part for agricultural use, has been rationalised. Here the key to success seems to be administrative continuity. Several states have recently organised an open contest that awards a Blue Environment Prize for initiatives by enterprises that result in a marked improvement of their productive unit’s environmental performance. The press publishes the winning initiatives and this publicity encourages more companies to compete and, at the same time, the public learns about the initiatives.

The challenge facing environmental authorities is to put into practice long-term and economically effective instruments. Innovation is needed in view of the region’s fiscal restrictions so that more use can be made of self-financing economic instruments. More economic flexibility and specific funds are needed to finance environmental management. The authorities should work with tax authorities, improving their capacity to comply with environmental regulations. Finally, potentially harmful subsidies should be eliminated, such as tax exemptions on fertilisers and pesticides which can cause more damage to the environment because of the increased use such exemptions may encourage.

Industries, new technologies and sustainable tourism Sustainable production of resources concentrates on three aspects: industry, new technologies and sustainable tourism. Industry has been traditionally considered ·

as detrimental to environmental conservation, but the new production technologies and approaches refute this. Sustainable tourism is a very good example of an industry that can have a low environmental impact invest a large part of its resources in sustainable development. In industry, most efforts have been made in the area of certification, which is closely linked to organic production. Production of organic crops in Latin America and the Caribbean continues to grow and they now cover 22 per cent of the area classified globally as being under organic management. Argentina, Brazil, Mexico and Ecuador have the largest areas under organic production and together represent 96 per cent of the region’s organic agricultural production. In only a

Environment Outlook

decade, Argentina increased its area certified as organic five times from 5,500 hectares in 1992 to 2.8 million hectares in 2001, mainly by certifying much of the pampa natural grassland. Most certified organic agricultural production is meat (beef and chicken) and sugar, cocoa, coffee, cereal and grain crops, as well as fresh fruits and vegetables, principally for export to markets in the United States and the European Union (García, 2002). Cuba has hugely increased its urban organic agriculture, which annually supplies more than one hundred and thirty million kilograms of products and employs more than 300,000 people. Some leading industries, generally large in size and productivity, adopt voluntary mechanisms to exceed environmental standards in order to position themselves to become more competitive (Fernández-Busto, 2001). In October 2002, Chiquita Brands International, the banana company, managed to obtain certification with an ECO-OK seal from the Rainforest Alliance for its regional operations. This covered all its estates in the region as well as 30 per cent of private estates that supply it with bananas. Production of these estates accounts for 15 per cent of all Latin American banana exports. In addition, the certification is subjected to a thorough annual review (Chiquita, 2002). A year earlier, Reybancorp, S.A. certified 100 per cent of its estates, all in Ecuador. The Rainforest Alliance, with the collaboration of the Sustainable Agriculture Network – responsible for setting environmental and social standards – has other certification programmes for coffee, cacao, citric fruit and ornamental plants which reduce the crops’ environmental impact and increase their social benefits. In the past decade, 58,392 hectares have been certified in Latin America (Rainforest Alliance, 2002). Another voluntary mechanism was put into effect in Costa Rica to address the polluting impact of residual coffee waste in rivers. In 1992 an inter-institutional con-

vention was established to begin a voluntary programme to reduce pollution by stages. Each coffee-producing process was assessed, each processing plant’s specific problems were identified and measures proposed to adequately treat solid and liquid wastes. Plant owners had to define and implement the best technical solution and there was a very strict control and follow-up process. The Ministry of Health carried out periodic inspections and coffee producers had to demonstrate compliance with effluent levels set out in the Regulation on Dumping and Re-use of Sewage Water (Executive Decree No. 26042 of 14 April 1997 and its reforms). At present the 118 remaining processors have adequate treatment systems and pollution has dropped by almost 98 per cent. It is hoped to execute a similar programme with sugar producers (Wo Ching and Moreno, 2001). The forestry industry is gradually adopting more modern technologies, in order to make it more efficient, and at the same time, strengthening small and medium-sized companies. Forest certification continues to increase. By 30 September 2002, the Forest Stewardship Council had recorded 111 certificates in 14 Latin American countries, for a total of 3,645,781 hectares certified (FSC,2000). The International Standards Organization (ISO) continues to issue more ISO 9000 and ISO 14000 certificates and the number of participating countries is increasing. Argentina, Brazil and Colombia obtained almost 90 per cent of the 14,423 ISO 9000 certificates issued to 33 countries in the region in 2001. Brazil and Argentina received 77 per cent of the 681 ISO 14000 certificates issued to 22 countries in the region that same year. In general, Argentina and Brazil have received more than 70 per cent of the two types of certificates issued in the region in 2001 (ISO, 2001). The new technologies play a central role in large development areas, alternative energies and the cleaner production centres network.

Companies and industries in the region are also looking for cleaner but profitable technologies. Successful

National Cleaner Production Centres (CNPL) have been set up with wide participation from different sectors and support from international organisations such as the United Nations Industrial Development Organization (UNIDO) and the United Nations Environment Programme (UNEP).

industrial residues, reviewing legal and institutional frameworks designed to promote technological change and to develop the environmental market, creating tax incentives for environmental investments and securing financing for them from development banks (FernándezBusto, 2001). The cleaner production approach allows integrated environmental management at company or industry level, reducing the impact on the environment and generating important benefits that include saving water, energy and fuel, treating sewage water, improving labour conditions and providing more training. In its initial phase, the UNIDO-UNEP Cleaner Production Centres global project helped to create eight centres in Brazil, China, the Czech and Slovak Republic, India, Mexico, Slovak Republic, Tanzania and Zimbabwe. In a second phase, centres were installed in Hungary, Morocco, Russia, Tunis, Vietnam, Costa Rica, El Salvador, Guatemala and Nicaragua, the four last-

mentioned members of the Central American Cleaner Production Centres Network (CCAD, 2003b). In 1999, UNEP, with support from Norway, began a four-year project to promote investment in cleaner production in developing countries, leading to attractive investment proposals for credit agencies. To demonstrate the international goals achieved, the project concentrates on five pilot countries in three regions: Guatemala, Nicaragua, Tanzania, Zimbabwe and Vietnam (UNEP, 2003b). Details are given below of the four Mesoamerican (Mexico, Guatemala, Nicaragua, Costa Rica) and two South American (Colombia and Chile) centres. In the case of Central America, it is important to note that – besides the national centres’ activities – in January 2002 the Regional Environmental Award System was created, promoted by the Central American Commission on Environment and Development to recognise Central American enterprises that have developed environmentfriendly products or processes (AGA, 2001).

Environment Outlook

The Mexican Cleaner Production Centre, constituted in 1995, is supported by the National Polytechnic Institute and the United States Agency for International Development (USAID). It has achieved improvements in environmental performance and increased production by more than 50 companies, in the following sectors: electroplating, foundries, chemicals, hospitals, sugar mills, food and bottling (IPN, 2003).

The Guatemalan Cleaner Production Centre seeks to strengthen local capacity to apply cleaner production and thus make national companies more efficient, competitive and compatible with the environment. Its members are the Industrial Chamber, the del Valle University and the Sugar Producers’ Association, and it is supported by UNIDO and UNEP, the Environmental Sciences Technological Institute of Basel and the Swiss government. Although only recently established, it has already prepared a study on investments in cleaner production in Guatemala and produced a series of Cleaner Production Training Models (CGPL, 2003). The Nicaraguan Cleaner Production Centre, at the National University of Engineering, made national-level technical assessments in 2001, identifying dairy products, abattoirs, sugar, coffee and fisheries as industries that most urgently need to apply cleaner production methods: It has also promoted the preparation of a national cleaner production policy, by publicising the concept of cleaner production and supporting it — by means of business plans — in obtaining industry financing. In 2001 it trained 229 people (UNI, 2003). The Costa Rican Chamber of Industry, the Technological and Informatics Management Centre and the Technological Institute of Costa Rica make up the National Cleaner Production Centre, which is financed by the Swiss Government’s Federal Office of Overseas Economic Affairs and receives technical support from the Basel Environmental Sciences Technological Institute. The centre offers advice on how to obtain ISO 9000 and ISO 14001 certification to companies in the following sectors: coffee production, chemicals, plastics, electronics, freight services, agriculture and airport terminals. The certified coffee growers together export 10 per cent of the national total, mainly to European countries (CNPML, 2003). In Colombia, the National Cleaner Production and Environmental Technologies Centre (CNPMLTA) is a private agency that offers the business sector advice and services. It was established in 1998 on the initiative of a group of institutions and companies, national and international, to stimulate environmental policies and activities in Colombian industry. It receives support from the Swiss Government through the Swiss Federal Institute for Materials and Technologies Research and Testing (EMPA), and the Swiss Ministry of State for Economic Affairs (SECO). Of particular interest is the CNPMLTA Regionalization Strategy with an implementation budget

Chapter

of US$380 million. Cleaner Production Regional Hubs have been established in five regions of the country: Caribbean, Santander, the South-west, the coffee–growing area and the centre of the country (CNPMLTA, 2003). In Chile there have been successful cases of cleaner production in the following areas: meat curers, printing, abattoirs, furniture, paints, marine products, tanneries, metalallomechanics, wine, dry cleaners, fisheries and foundries (CITC, 2003). After industry and new technologies comes sustainable tourism. In Costa Rica the government has implemented a sustainable tourism certification programme (CST), welcomed by the World Tourism Organization, which organises hotels into different categories, depending on their level of environmental impact. (ICT, 2003). This certification system will soon be adopted by more Central American countries. In May 2002, the year designated as International Ecotourism Year, the First Summit of Ministers of Tourism and the Environment of Latin America and the Caribbean took place in the Galapagos Islands, Ecuador, and produced the Galapagos Declaration. In the declaration, the Ministers support the initiative of Colombia, Panama, Costa Rica and Ecuador to establish the first

Environmental Innovation Prize The Environmental Innovation Prize is promoted by CCAD and financed by the government of the Netherlands, the United States Agency for International Development (USAID), and the United States Environmental Protection Agency (EPA). It is awarded to companies that make an effort to improve their products and processes and introduce innovations to reduce damage to the environment and increase competition. Information on the winners is published in the press in Central America and winners are entitled to use an emblem on their advertising material. Three companies, one small, one medium-sizedand one large, receive a prize for developing innovative projects in any of the following categories: · Product Ecodesign prize: for the product, service or system that is redesigned to minimise environmental damage, at least during several stages of its life (design, raw material, manufacture, distribution, use and final disposal) and the development that has made a company more competitive and better able to satisfy its consumers' needs. · Environmental Technological Innovation prize: for companies that have improved their environmental performance and competition, thanks to the development of new management processes or systems, or improvements, whether gradual or radical, in processes or systems, in supplying resources, producing goods or services, marketing, distribution of goods and services, final disposal of waste and management. The initiatives imply modifications for the company, although not necessarily new either nationally or internationally. · Energy Efficiency prize: for companies that have improved energy efficiency with technological changes in their production processes, transport or distribution systems, through energy-saving programmes, or by changing to renewable or cleaner energy sources. Any Central American country may participate, with the following criteria: · Central American companies: Central American countries of any size and multinational companies operating in Central America. · Private and public companies in any sector: Industry, agriculture or services. · Reduction of environmental impact: The project (innovative product or process) must show environmental improvement. · Environmental benefits above standards in force: Participants should show that standards for the project are above those prevailing in the country. · Recently-developed projects: Participating projects must have been developed during the past three years. · Ecodesigned product with commercial potential: For the Ecodesign category, the products must be on the market or undergoing final tests before being marketed. For the other categories, the technological changes in processes must be implemented by the company. Source: CEGESTI, 2002.

They suggest a study be made on how to harmonise national legislation on tourism and the environment and adopt a regional system to assess the environmental impact of tourism (WTO, 2003).

Principal challenges In the industrial and technological fields, small industries should enter the certification movement now dominated by large companies. Here an important role could be taken by non-governmental organizations

(NGOs) who could establish networks responsible for fixing environmental and social standards for small and medium-sized enterprises. Small countries should also enter fully into the field of certification, now dominated in the region by only three countries which (depending on the type of certification) receive between 77 and 90 per cent of the certificates. More cover should be given to the Cleaner Production Centres network and the example of the Regional Environmental Award System, promoted by the Central American Environment and Development Commission, should be followed. Finally, systems based on ecotourism experiences throughout the region should be drawn up, and coordination improved and expanded.

Environment Outlook

Environmental financing sources and mechanisms In spite of some notable efforts, during the past decade the international community’s investments in support of sustainable development have been insufficient to meet the goals of Agenda 21. Besides what might be called fast track financing, which is foreign debt forgiveness and cancellation (freeing resources for environmental use), sources of financing include global, regional, sub-regional and national funds. Of great relevance in this context are actions taken by a number of countries in the region to establish national environment budgets in the public sector, and private participation. Various circumstances must be borne in mind to understand the evolution of international financing in this field (Bárcena and de Miguel, 2001). On the positive side, although it is limited, is the contribution of different international multilateral organizations, including the creation of concessionary funds. Other conditions are mostly adverse and include the growing foreign debt volume and the impossibility of sustaining it, the reduction of official development assistance and the direction of private international financial flows, which concentrate on developed countries and emerging economies. Various mechanisms have been tested to mitigate the effect of the foreign debt on Latin American and Caribbean countries. In 1996, the World Bank and the International Monetary Fund (IMF) launched an initiative for heavily indebted poor countries and expanded in 1999. Bolivia, Guyana, Honduras and Nicaragua benefited from debt cancellations of US$2,060; 1,030; 900; and 4,500 million respectively (Bárcena and de Miguel, 2001). Another mechanism is the debt-for-nature swap – partial cancellation of foreign debt in exchange for mobilising national resources to protect the environment. These swaps have been taking place since 1987 in Bolivia, Costa Rica and Ecuador, with the participation of non-governmental organisations (NGOs), most of them international. Nevertheless, the debt-for-nature swaps represent less than one per cent of the foreign debt of Latin America and Caribbean countries. Costa Rica has entered into most of these transactions, but to an amount equal to only five per cent of its total foreign debt. Ecuador has also been active in using this mechanism. On the other hand, the 1996 tropical forests conservation law of the United States extended the swap mechanism to the protection of very important tropical forests in developing countries, with budgets of US$50 million for 2002, US$75 million for 2003 and US$100 million for 2004 (Bárcena and de Miguel, 2001). In 2001, several countries, including Chile (Maldonado,

205

2002) and Paraguay (Zavala, 2002), used the debt-fornature swap as an environmental management financing mechanism. Official development aid has steadily fallen over the past 10 years (Bárcena and de Miguel, 2001). Between 1992 and 2001, it was reduced by one-third from 0.33 to 0.22 per cent of the gross domestic product (GDP) of donor countries, in spite of the goal of 0.7 per cent set at the Rio de Janeiro summit. Aid for Latin America and the Caribbean was reduced form US$5,200 million in 1998-1999 to close to US$5,000 million in 1999-2000, representing about 12 per cent of total or 0.34 of regional GDP in 2000. Nicaragua, Honduras, Bolivia and Peru, in that order, benefited most, with 38 per cent of the regional total. Within the total official aid the amount for general environmental protection (not including environmental financing assigned to sectoral activities) grew in Latin America and the Caribbean from one per cent in 1990 to five per cent in 1996, only to decline again to three per cent in 2000 when it was equal to 0.01 per cent of regional GDP. Globally, there has been an increase in aid to protect water and land resources; however, aid for the marine sustainable development, protection of the atmosphere, sustainable agriculture and to combat desertification fell from 25 to 17 per cent between 1996 and 1999. Private financial flows are very much higher than official development aid. The largest recipients of direct foreign investments (DFI) over the past five years were Brazil, Mexico and Argentina, while in Central America and the Caribbean they were Panama, the Dominican Republic and Trinidad and Tobago. Generally, the increase in DFI is due to a redefinition of strategies by transnational companies as a response to internationalisation, in opening to third markets or as a market defence. Another factor that explains this trend is the access allowed to the private sector, both national and foreign, to previously-restricted activities, such as public service markets – finance, energy, telecommunications – and the extraction of natural raw material resources – natural gas, mining, hydrocarbons (Bárcena and de Miguel, 2001). Although the increase in DFI could eventually lead to the transfer of more environment-friendly technologies, up to now – as indicated in Chapter Two – it has led to more regional exports with contaminating production processes, as well as a reduction in public capacities to control such processes. International cooperation continues to be a significant source of funds for very important sub-regional projects, with or without national counterpart funds. In Central America, all the consultative processes carried out to prepare the National Biodiversity Strategies and their respective action plans were made possible thanks to resources from the GEF (Wo Ching, 2001). On the other hand, the Amazon Cooperation Treaty has received resources from governments in countries such as The

Investment in biodiversity in Latin America and the Caribbean In spite of the importance of biodiversity in the region, the threats to which it is subjected and the substantial investments made to halt its degradation, hardly any studies have been made on the financial resources needed to conserve it. USAID, the World Bank and the Biodiversity Support Programme prepared a survey to collect information on projects. It was distributed to 118 main donor organizations and did not include national public spending or profit-making investments. From replies sent by 65 financing sources (including the most important), it was estimated that 3,489 conservation projects were financed between 1990-1997, representing an investment of US$3,260 million. Brazil received most funds, followed by Mexico with, together, 45.5 per cent of country funds. However, most funds per square kilometre were received by Venezuela, all the Central American countries, Ecuador, Dominican Republic, Haiti and Jamaica. The southern cone and Cuba received less. The 13 financing organizations that contributed 77 per cent of the total included the World Bank (16.7 per cent), IBD (11 per cent), GTZ of Germany (8.8 per cent), USAID (6 per cent) and GEF (5.7 per cent). Projects on natural resources and protected areas management absorb more than 70 per cent of the finances. On the other hand, only 32 per cent of projects can be classified as being in the ecoregions category within which 66 per cent of funding is allocated for tropical and sub-tropical broadleaf forests. Advances in conservation over that past two decades have undoubtedly been made, but more are needed as dangers to biodiversity continue to grow.

Mesoamerican Biological Corridor and Amazonia. In 2001, there were 81 projects executed with funds of US$2,350 million. In 2000 the IDB allocated US$142 million – 2.7 per cent of the Bank’s total loans, without taking into account projects on water supply and treatment – for environmental projects (Bárcena and de Miguel, 2001). On forestry alone, the IDB, the World Bank and the GEF jointly financed projects worth US$2,700 million in 1999. Of these funds, 72 per cent came from the World Bank with 50 projects, while the IDB contributed 20 per cent for 60 projects. The GEF financed 11

projects. Of total multilateral funds, 43 per cent went to Brazil; Mexico was a long way behind with nine per cent (Puustjärvi and others, 2002). International funding, although on a somewhat smaller scale, also came from sub-regional banks that allocated part of their resources to environmental activities. In 2000, the Andean Development Corporation approved a non-repayable technical cooperation grant of US$441,000 or 3.4 per cent of total aid (Bárcena and de Miguel, 2001). On 14 May 2002, the Central American Bank for Economic Integration (CABE) signed a credit agreement with the AB Svensk Exportcredit Bank, of Sweden, for US$10 million to promote development projects in Central America, in both the public and private sectors. The loans will be given with a subsidy from SIDA, the Swedish Cooperation Agency, of 35 per cent to finance part of the interest for 10 years with a grace period of a-year-and-a-half, and up to US$2.5 million per project. These loans are to purchase Swedish capital goods, services and technological assistance for solid waste or sewage treatment, drinking water, agriculture

or fishery machinery, wind and geothermal energy, and in rural areas, equipment for the food industry, medical equipment, telecommunications and environmental solutions (Barletta, 2002). In recent years various multilateral environmental concessionary funds have been established to finance sustainable development projects. The GEF, established in 1991, is the most important fund and has spent some US$3,200 million on the basis of national counterpart funds of approximately US$8,000 million in 150 countries to implement 800 projects on: ·

on persistent organic pollutants.

The Latin America and Caribbean region has received more than US$180 million – 43 per cent allocated to Brazil and Mexico – and there are projects approved for more than US$700 million (24 per cent of the Facility’s commitments -Bárcena and de Miguel, 2001). In addition, the Montreal Protocol Fund, through the World Bank, has promoted regional operations valued at US$50 million in Argentina, Brazil, Chile, Colombia, Ecuador, Mexico, Uruguay and Venezuela. National trends in seeking development financing mainly include obtaining fiscal resources, allocating public sector environmental budgets, and private participation. Annual environmental budgets vary considerably from year to year so that it is very important to use innovative economic instruments. Increasing private sector participation, with access to new funding sources, is especially aimed at investment in better technologies and energy efficiency, control of emissions and treatment of sewage and solid waste (Bárcena and de Miguel, 2001). National sources are relatively more important than international sources, except in the case of small island states in the Caribbean for which outside aid continues to be fundamental but, even for them, there has been a reduction in available funding (UN, 2002a). National resources may be generated by allocating specific funds for environmental projects that take advantage of international mechanisms such as restructuring foreign debt. One mechanisms is debt swap for environmental investment or even partial or total cancellation of the debt. The resulting funds are added to national counterpart funds as has happened in Bolivia (biodiversity), Brazil (forests), Chile (environment) and Paraguay (wildlife areas). Some are in the form of trust funds, such as the Ecological Trust Fund of Panama (UNEP, 2000). Paraguay has established the PR 116 Environmental Fund with the help of the IDB (Zavala, 2002) and Guatemala also has a similar fund (Acquatella, 2001). In Bolivia, the National Fund for the Environment (FONAMA), created in 1990, gives small and medium-sized donations to NGOs, and finances the GEF Biodiversity project, a national parks foundation and the USAID forestry project. When it was set up, it received commitments from donors for a total of US$70 million, but it has lost some of its credibility (OAS, 2001). In some sectors, such as forestry, several countries have become adept at using financial instruments to collect additional funds for sustainable forest management. Economic fiscal instruments have been developed (taxes, royalties, environmental rates, public sector financial mechanisms (loans, credit lines, subsidies, forestry and environmental funds, donations), as well as

·

Chapter 3: Policy responses to environmental problems

other market mechanisms (carbon fixing certificates, water tariffs). There are also combined financing formulas, for example receiving GEF funds linked to IDB loans for biodiversity conservation projects with international benefits (Puustjärvi and others, 2001). The total environmental cost in Latin America and Caribbean countries is usually not more than one per cent of GDP, and public environmental costs are no higher than three per cent of total public spending (with exceptions, as will be seen later). High administrative costs – due to poor management and control policies – account for most of the funds spent and much less is invested in direct environmental costs. Among the latter, the amount spent on administering and managing water resources is usually more than the combined amount allocated for spending under the other two important headings: managing solid waste and protecting natural areas. Important, although still modest, advances have been made in self-financing the administration of national parks and paying for environmental services programmes. The past decade has seen a growth in private environmental spending so that it is essential that good relations and practices be established with the private sector. In many cases, local corporations or municipalities are responsible for spending part of the environmental budget, usually after negotiations with the central government environmental authority or ministry. This poses the challenge of improving country-wide horizontal and vertical institutional coordination, but it presents an opportunity to develop integrated environmental policies and to optimise cost distribution (Bárcena and de Miguel, 2001). In Argentina, environmental costs in 2000 were estimated to be US$440 million, equal to 0.6 per cent of national and provincial public spending. The private sector cost is calculated as slightly higher at around US$480 million. In Chile, environmental public spending has shown a sustained rise since 1990, increasing in a decade from US$300,000 annually to US$285 million in 2001. The trend in Costa Rica has been similar: the average investment in the 1990s was US$66 million but went from US$26 million in 1992 to US$100 million annually in the three-year period 1998-2000, which was 4.5 per cent of total public spending in 2000 (UNEP, 2000). In both countries, these costs came mostly from public funds and less than eight per cent from international cooperation. In Costa Rica, most spending has been on forest ecosystems, water, treatment of wastes, and soils. This investment has brought a reduction in deforestation, recovered degraded areas and increased awareness of the environment among the population in general (Bárcena and de Miguel, 2001). In 2001 Colombia budgeted US$87 million for the National Environmental System (SINA), 70 per cent of which was for regional autonomous corporations. In

Environment Outlook

keeping with this decentralised system, resources from the national environmental budget have been falling, while corporations’ incomes have been increasing. In Mexico the total budget of the Ministry of the Environment and National Resources (SEMARNAT) for 2000 was over US$1,500 million of which 21 per cent was for direct environmental spending with a much larger percentage spent by the National Water Commission (Bárcena and de Miguel, 2001). In Trinidad and Tobago, the total environmental cost is financed with an important international cooperation contribution, channelled through NGOs. As to national resources, at the end of 2000 the government established the Green Fund financed from a tax equal to 0.025 per cent of the gross income of companies. Estimates show the fund may be able to collect between US$12 and US$20 million annually. Although administered by the Ministry of the Environment, its goal is to finance environmental projects formulated by NGOs (Bárcena and de Miguel, 2001). After reviewing the main trends in national and international financing in the region, it should be stressed that many of the initiatives receive mixed resources from

209

different sectors of civil society, both in the region and from outside. The importance of joining forces when seeking new resources must be recognised and, in this respect, the participation of NGOs has been vital in many cases. The Nature Conservancy (TNC) and the Multilateral Investment Fund of the IDB, joined forces to create the EcoEnterprises Fund, which provides financial, technical and administrative support to increase the long-term sustainability of companies with environmental responsibilities and work in cooperation with local or community conservation groups and non-profit organisations in Latin America and the Caribbean (2003). The trends and examples described are an outline of the present panorama of financing environmental activities. This panorama was presented and discussed at the International Conference on Financing for Development, held in Monterrey, Mexico, in March 2002 and sponsored by the United Nations. It was attended by more than 50 heads of state and 200 ministers, as well as representatives of the private sector, civil society, and inter-governmental financial organisations. The Conference established an approach to development financing – expressed in the Monterrey Consensus – and Chapter

3 Monterrey Consensus: development financing I. How to confront development financing problems: a global response Among the main commitments of the Monterrey Consensus is the call for an alliance between developed and developing countries. It hopes to reach the internationally-agreed development goals, including those established in the Millennium Declaration and, in particular, to eliminate poverty, improve social conditions and the quality of life, and protect the environment. Making the problem international presents opportunities but also raises difficulties. To take advantage of the opportunities and overcome the difficulties, more collaboration is needed between countries and more integration of national and international policies. To achieve this, participating countries promised to promote national and global economic systems based on the principles of justice, equity, democracy, participation, transparency, responsibility and inclusion. II. Principal measures Development needs include more national resources, maintaining an adequate production level, improving human capital, private sector stimulation, and attracting and taking advantage of investment and international aid. Good public management is indispensable so that much is made of fighting corruption and there is even discussion of a convention on the subject. Macroeconomic policies should be rational and a sound legal and regulatory framework is needed. Favourable conditions must be created for foreign investment flows, as well as mixed funding mechanisms (public and private sectors). The decisions taken by the World Trade Organization are welcome as is the commitment to liberalise international trade in order to promote development. The need is recognised for a substantial increase in official development aid until it reaches 0.7 per cent of the GDP of developed countries, as well as a reduction in the foreign debt. Finally, better coordination is called for between the United Nations, the World Bank, the International Monetary Fund and the World Trade Organization. A conference in 2005 will follow up on these commitments. Source: Asamblea General de las Naciones Unidas, 2002.

discussed economic matters of global importance (Asamblea General de las Naciones Unidas, 2002).

Principal challenges In the financial field, pressure must be kept up on the international community to increase its sustainable development aid in the region which, over the past decade, has fallen short of the goals set by Agenda 21. At the same time, action taken by different countries in the region to establish national environmental financing sources must be extended. Efforts should be made to include foreign debt reduction and to redirect private international financial flows so that they do not concentrate on developed countries and on emerging economies. Direct foreign investment should respond to the interests of nations and not only to the strategies of transnational companies. Sub-regional banks should maintain and, as far as possible, increase their already significant support for environmental activities. Finally, it is important to maintain the GEF, by promoting sustainable development projects with local counterparts.

Public participation Recent years have seen an important development in public participation in environmental management, although with differences between countries. One of its particularly notable facets is the creation of specialised institutions, both nationally and across borders. Also important is the use of new communication technologies to promote and develop environmental processes.

Institutional participation Considerable growth has occurred in several countries in the number of public, private and mixed institutions, agencies and organisms that promote citizen participation in matters concerning the environment. One of the pivotal points of development in this respect has been participation in managing protected areas, particularly considering that governments lack technical and financial resources. Among the principal strengths of these types of participatory processes is that they have shown themselves to be a good means of solving conflicts, especially those related to managing natural resources. In some cases, the processes have ended by the installation of a permanent environmental participatory management body. Participatory processes have also been the determining factor in seeking resources and in managing ecosystems or transboundary basins. In Mesoamerica and the Caribbean, various initiatives are linked to the UNDP’s Capacity 21 project and facilitated by the Earth Council. In Mexico there has been an increase in civil society’s participation in regional sustainable development consultative councils.

Chapter 3: Policy responses to environmental problems

Use is made of the Integrated Multisectoral Sustainability Planning approach to promote and improve integration of multilateral conventions, both nationally and locally (Consejo de la Tierra, 2001). On the other hand, the Consultative Sustainable Development Councils are concerned with land regulation as an essential tool, with a notable influence on the description, diagnosis and forecasting phase of the General Ecological Regulation of Mexican Territory and, more recently, in proposing and managing local regulations. They have also played an essential role in disseminating information and awakening public awareness about climate change. In some states, such as Veracruz, this participation has led to the application of private conservation instruments, such as ecological rights (Gutiérrez, 2002). In Honduras the National Convergence Forum (FONAC), created by legislative decree No. 155-94, allows for high-level discussions on social, economic and environmental themes and it has proved its worth in dealing with the emergency caused by Hurricane Mitch in 1998. In July 2002, a technical and financial agreement was signed with the Forum to Strengthen Democracy (FFD). This Forum was established to promote citizen participation in strengthening democracy and national development (FFD, 2003). Caribbean examples can be cited in the Dominican Republic, Saint Lucia and Jamaica. The Solidarity Foundation of the Dominican Republic seeks to strengthen the decision-making capacity of other organisations to participate in and to facilitate collaboration and coordination processes among community groups, the government and the private sector (Fundación Solidaridad, 2003). In this country it has also been possible to mobilise public and private stakeholders towards adopting a strategy of training and disseminating information on institutional strengthening and environmental conventions. Action has been taken to support and seek consensus on approving Law 64-00 on the Environment and Natural Resources. The four provinces that make up the Enriquillo sub-region have engaged in a multisectoral planning process to integrate environmental conventions. In Saint Lucia the public has participated in developing sensitive environmental areas through the Soufrière Marine Management Area (SMMA), a multisectoral body with representatives from government, NGOs and the tourism industry. This zone is administered under a management plan that covers four categories: marine reserves, priority fishing areas, multiple-use areas, and recreation areas (SMMA, 2002). In Jamaica, the Foundation for Caribbean Coastal Areas Management (CCAM) oversees the recently-declared Portland Bight Sustainable Development Area to set up and formalise local fisheries associations and the Portland Bight Fisheries Management Council (PBFMC). The PBFMC and other similar councils are drafting regu-

Millennium Declaration: advances in compliance At its 55th General Assembly in 2000, the United Nations approved the Millennium Declaration consisting of a series of sustainable development commitments. At the 56th General Assembly, member states approved a guide to set compliance goals and indicators. At the 57th General Assembly, a report was given on advances in implementing the declaration over the past two years. In general, slow progress is being made in Latin America and the Caribbean. Advances have been made in universal primary education, but there are still gender inequalities. When it comes to health, the supply of antiretroviral medicines has reduced the mortality and morbidity rate; this is especially notable in Brazil and will soon be seen in other countries in the region. However, the Caribbean is in second place in the prevalence of HIV/AIDS among adults. The environment remains fragile. Latin America has not been able to halt its high rates of deforestation. Globally, the consumption of chlorofluorocarbons (CFCs) has been reduced and energy is being used more efficiently, although the requirements of the Kyoto Protocol have not been reached. Priorities indicated by the Secretary General for future years concern water and sanitation, energy, health, agriculture and biodiversity. Strategies to reach these goals combine efforts made by states and international organisations with those of NGOs, the private sector and other civil society sectors. The Secretary General concluded his report by saying that, given the right national and international economic conditions, and if the necessary financial resources are made available, it is still possible for all regions of the world to comply with all, or nearly all these objectives (UN, 2002b). The declaration has various chapters that contain indications of states' commitments and objectives: I. Values and principles II. Peace, security and disarmament III. Development and poverty eradication IV. Protection of our common environment V. Human rights, democracy and good government VI. Protection of vulnerable persons VII. Special attention to African needs VIII. Strengthening the United Nations At the 56th General Assembly, states approved a guide that established more precise objectives, 18 goals and 48 indicators for compliance with the Millennium Declaration. During the 57th General Assembly the first report was delivered on advances in complying with the declaration. The following table is a summary of advances as of 2001, relating to the goals fixed for 2015.

Objectives Objective 1. Eradicate extreme poverty and hunger

Objective 2. Universal primary education

Goals

Advances in Latin America and the Caribbean

Goal 1. Between 1990 and 2015, reduce by half the percentage of people with less than $1 a day to live on

The percentage went from 17 per cent in 1990 to 15 per cent in 1999, showing a very slow advance. The poverty gap coefficient passed from 5.2 per cent in 1987 to four per cent in 1998.

Goal 2. Between 1990 and 2015, reduce by half the percentage of people suffering from hunger

The region is reaching the goal for the infant population. In 1990, the percentage of underweight children was 11 per cent and dropped toeight per cent in 2000. The percentage of the population below the minimum food consumption level dropped from 13 per cent in 1990 to 11 per cent in 1999.

Goal 3. Ensure that, by 2015, boys and girls throughout the world complete a full cycle of primary education

The rate of primary education enrolment increased from 85 per cent in 1990 to 94 per cent in 1998 in Latin America, while in the Caribbean in the same period it increased from 62 per cent to 80%. Literacy in people 15-24 years of age rose from 92 per cent in 1990 to 94 per cent in 2000.

Millennium Declaration: advances in compliance (continuation) Objective 3. Promote gender equality and women's autonomy.

Goal 4. Eliminate gender inequalities in primary and secondary education by 2005, and at all levels of education by 2015.

Gender inequality still exists at all levels in developing countries, although to a lesser extent in Latin America and the Caribbean. However, the percentage of women earning wages in non-agricultural sectors only rose from 37 per cent in 1990 to 41 per cent in 2000, while parliamentary seats occupied by women only went from 11 per cent in 1990 to 16 per cent in 2000.

Objective 4. Reduce infant mortality.

Goal 5. Between 1990 and 2015, reduce mortality in children under 5 by two-thirds.

Of 43 infant deaths for every 1,000 live births in 1990, the figure was still 29/1 000 in 2000, and in those under 5, the rate fell from 54/1,000 in 1990 to 37/1,000 in el 2000.

Objective 5. Improve maternal health.

Goal 6. Between 1990 and 2015, reduce maternal deaths by threequarters.

Among developing countries, the region has the lowest rate of maternal deaths: 190/100 000 (1995) live births and the highest rates of births attended by qualified health personnel: 85 per cent (2000)

Objective 6. Fight HIV/AIDS, malaria and other diseases.

Goal 7. By 2015, halt and start to reduce the spread of HIV/AIDS.

In 1999, the percentage of morbidity in young people between 15 and 24 was 0.5%. 600 children have been orphaned by HIV/AIDS (2001).

Goal 8. By 2015, halt and start to reduce the incidence of malaria and other serious diseases.

In 2000, the death rate from malaria was 1/100 000 children up to four years of age, while the rate for tuberculosis was 11/100,000 habitants.

Goal 9. Include sustainable development principles in national policies and programmes and reverse the loss of the environment's resources

Globally, CO2 emissions per capita are practically the same as they were a decade ago. On the other hand, the consumption of CFCs has dropped to a tenth since the Montreal Protocol was approved. Energy use is more efficient. There is less forest cover although the percentage of areas set aside for biodiversity protection has increased.

Objective 7. Guarantee the sustainability of the environment

Goal 10. By 2015, reduce by half the percentage of people without access to drinking water. Goal 11. By 2020, considerably improve the quality of life for at least 100 million people living in slums. Objective 8. Promote a world development association

·

The percentage of people with sustainable access to improved drinking water supply increased from 82 per cent in 1990 to 86 per cent in 2000. There was hardly any change in the percentage of the urban population with access to better sanitation services, from 85 per cent in 1990 to 86 per cent in 2000.

Goal 12. More development of an open trade and financial system, based on standards, predictable and non-discriminatory. Includes the commitment for good management of public affairs and a reduction in poverty, in every country and internationally.

Official development aid (ODA) in 2001 was US$51,300 million, of which US$11,800 million were allocated to the least developed countries. These amounts are less than in 1990.

Goal 13. Attend to the special needs of the least developed countries. Include free Customs access and export quotas for the least-developed countries; the improved debt relief programme for very indebted poor countries and the cancellation of the

The official aid total for the least development countries has been reduced over the past decade and is now at its lowest ever level 0.05 per cent of the GDB of developed countries in 2001- from a total of 0.22%.

Attend to the special needs of developing land-locked countries and small island developing states (by means of the Action Programme for sustainable development of small island developing states and the results of the 22nd period of sessions of the General Assembly).

The ODA received by land-locked countries dropped to 6.6 per cent with respect to their gross national income, while for small island developing states it fell to 2.1 per cent.

Goal 17. In cooperation with pharmaceutical companies, give developing countries access to essential medicines.

In 1999, about 64 per cent of the regional population had stable access to essential medicines at reasonable prices, compared to 70 per cent globally.

Goal 18. In collaboration with the private sector, ensure that advantage can be taken of new technologies, in particular of information and communications technologies las tecnologías de la información y de las comunicaciones

In 2001, developing countries had 16.8 subscribers to telephone and cellular phone services, 2.4 personal computers and 2.8 Internet users for every 100 inhabitants, figures very much below those in developed countries.

lations on the use of land and marine resources. They have also successfully settled a dispute about petroleum installations in the Portland Bight marine area (OAS, 2001). Among the participation initiatives in South America, mention may be made of significant experiences in Brazil, Paraguay and Argentina. In Brazil the territories of the Macuxi indigenous people, which had been colonised by farmers, livestock breeders and miners, were recognised and demarcated. The capacity of the indigenous people to participate was strengthened, and they were finally able to take their place at the negotiating table. Their ownership of the lands was recognised in 1998 (Maior, 2003). Furthermore, in Paraguay there is

an incipient programme of sustainable wildlife fauna use centres (CASFAS) (Zavala, 2002). There are also gradual participation experiences that need to be strengthened, such as that of Argentina where public participation mechanisms have been introduced into the national and provincial constitutions. There is now more public awareness about the environment, but these mechanisms are still little used and even ignored, in part because of the country’s serious institutional and economic crisis (Kohen and others, 2001). Laws recently approved are No. 25432 of 23 May 2001 on Binding and Non-Binding Public Consultation, and No. 12457/ 01 of 5 July 2001 of the Province of Buenos Aries, recognising all individuals or companies with a legitimate

interest in, or right of access to, administrative documents. These laws establish important mechanisms for participation.

and live in urban zones. Also, access is very varied from country to country (see section on Socio-economic trends in Chapter 2).

In addition to the national cases mentioned, participation is essential in managing transboundary resources or ecosystems, as has been seen in Honduras, Costa Rica and Argentina. The Three Nations Alliance for the Conservation of the Gulf of Honduras is a network of environmental NGOS SET UP to channel actions including conserving the manatee, preparing a protected zones network, solving port security conflicts and problems., In view of the failure of formal mechanisms, the Alliance is now studying the possibility of designating officials of the governments of Honduras, Guatemala and Belize as observers, to meet informally every three months, OAS, 2001).

New Internet sites allow complaints against public officials to be registered and followed up, making public accounting systems more transparent. Some national and international environmental campaigns are coordinated in record time with the help of e-mail or Internet pages. Many of them ask that letters be sent to members of national assembles asking them to approve or reject a law, or to other environmental authorities requesting that a decision be taken on a particular subject.

Between Costa Rica and Nicaragua, in the San Juan River basin, there is a binational management organisation with active participation not only by the communities but also by the municipal governments in both countries’ border cantons. In another case in Costa Rica, the objective was to establish an Agenda 21 for the Osa Conservation Area (ACOSA), bordering Panama, which has exceptional natural wealth under serious natural threats, which suffers from poverty and social conflicts, but, at the same time, has great economic potential. A pilot project has been considered to demonstrate its capacity for joint operation and management with wideranging participation. This mechanism has served to create and coordinate fora including a high-level interinstitutional commission, and environmental commissions in the three municipalities involved, implying months of work – and to define priority development problems. They have also sought joint solutions – and in only two years have made advances in road construction, electrification, telecommunications, health and the environment. Each party’s contributions have been monitored and national efforts related to local needs and proposals. To manage the Bermejo River basin in South America, between Argentina and Bolivia, a binational water commission was set up to develop an Integrated Basin Management Programme. This commission has strengthened coordination between the authorities of both countries, allowing a complete management plan to be designed and community participation strategies to be adopted (OAS, 2001).

New participation technologies The mass communication media and innovations such as Internet – especially e-mail – permit information to be obtained and distributed globally and international events to be coordinated quickly and at very low cost. However, it is important to remember that most users of these technologies are young, well-educated

·

Chapter 3: Policy responses to environmental problems

The World Summit for Sustainable Development (Rio + 10), held in August and September 2002, took advantage of these new technologies, allowing participation and follow-up by environmental NGOs and by citizens in general, throughout the continent (UN, 2003). Multilateral bodies wishing to have more contact with NGOs and other civil society organisations, have created interactive pages. Such is the case of the FAO Regional Office that makes documents available to everyone, and has sections on opinions, news, links, projects and joint events (FAO, 2002b). There are national examples in Mesoamerica (Mexico, Honduras, Nicaragua and Costa Rica) and in South America (Uruguay). The web page of the Ministry of the Environment and Natural Resources (SEMARNAT) of Mexico contains a section where citizens may give their opinions on the state of the environment in the country: a survey gives the ministry input about opinions expressed on the quality of its environmental management (SEMARNAT, 2003). In Honduras, an artisanal fishermen’s organisation prepared and sent to Congress a video tape showing the illegal destruction of mangroves by commercial farmers with political influence (UNDP, 2001). In Nicaragua, several organisations – the Centre for Constitutional Rights, Hagamos Democracia, the Sustainable Development Network and the Arias Peace and Human Progress Foundation – have constructed a web page to report on legislation pertaining to citizen participation. This site also contains a Citizen Participation Draft Law that may be consulted and opinions expressed, with the promise they will be taken into consideration (RDSN, 2000). In Costa Rica, a network of organisations and individuals directed a whole campaign based on a company’s request for permission to explore for oil on the Caribbean coast, and managed to get the authorities to refuse it because of the predicted environmental impact (ADELA, 2002). Uruguay’s Green Line came into existence eight years ago, following a wetlands protection campaign organised by the Uruguayan Healthy Environment

Group. The Interdisciplinary Development Study Centre (CIEDUR) operates with the support of national and foreign institutions. If offers free information and advisory and documentation services on environmental subjects, by organising consultations and attending to complaints, and has placed an Internet page and telephone line at the public’s disposal (CIED, 2001).

tives have been promoted in the region to establish more advanced environmental information systems that include the systematic compilation of data and indicators, as well as the publication of periodic reports on a broad range of subjects. Many of these systems – a necessary basis to determine actions and policy adjustments – are available on the Internet to the public.

Principal challenges

Forestry is an example of a recent advance in environmental monitoring. Within the framework of a global process promoted by FAO, following the Rio Summit and its declaration of principles on sustainable forestry regulation, in 1995 the Amazon Cooperation Treaty (ACT) countries initiated the Tarapoto Process (named after the Peruvian city when it began) by arranging national consultations on the adoption of sustainability criteria and indicators for the Amazon forest (Toledo, 2001). Between December 1996 and May 2001, national consultations were held in Bolivia, Brazil, Colombia, Ecuador, Guyana, Suriname, Peru and Venezuela, and the ACT secretariat is now preparing a project to validate the selected criteria and indicators.

In the field of public participation, stakeholders should not be limited to the local level, but should act in coordination beyond provincial or national borders on preparing, managing, implementing, monitoring and assessing environmental and development policies. Public participation should be considered as basic for successful and long-lasting environmental management. Countries in the region must strengthen participatory processes by innovation, both in the financial aspect and by taking advantage of available technology to achieve participation that is broader, transparent and economical.

Environmental information In the period 1972-2002, information on the environment was first collected in Latin America and the Caribbean by different drinking water, urban and industrial and other agencies monitoring activities that caused pollution. These specific actions have been gradually gathering strength, in many cases stimulated by environmental conferences and multilateral agreements. Furthermore, in recent years a number of initia-

In Central America, countries promoted a similar process known as Lepaterique named after the Honduran city where it began. It ended in 1997 with the identification of a set of criteria and indicators for sustainable forest regulation on a sub-regional, national and unit management scale. The Central American Forest Strategy approved by the CCAD in October 2002 also includes a project to validate the proposed criteria and indicators in order to establish a Central American monitoring system to measure progress on sustainable management of forest ecosystems (CCAD, 2003a).

Latin America and the Caribbean

In the field of biodiversity, in 1999 the CCAD, together with the National Aeronautics and Space Administration (NASA) of the United States, began preparing maps on living zones, land use, geological and hydrological structure, to be used in developing the Mesoamerican Biological Corridor. This information will serve to establish an environmental data and information system, analyse use options, and exchange information between Central American and NASA researchers. The project, with a budget of US$12 million, will terminate at the end of 2003 (CCAD, 2003d). One of its objectives is the preparation of the first Central American biodiversity report, applying an ecosystem approach (CBM and others, 2002). In Mexico, the National Biodiversity Commission (CONABIO), in accordance with the General Law on Ecological Balance, created the National Biodiversity Information System (SNIB). Through the Global Bio-diversity Information Network, the SNIB makes available to scientists, decision-makers and the public in general, standardised information on more than three million examples from almost 400 national and foreign collections. This information has already been used to prepare a series of analyses and studies for decision-making on commercially-important native species, protection measures, the granting or denying of permits, the risk of introducing modified live organisms and invasive exotic species, as well as establishing positions to be taken by the Mexican Government in international fora (CONABIO, 2003a). The Costa Rican National Biodiversity Inventory has an entomological collection of 2,959,258 examples, with 24 per cent identified as species; a botanical collection of 52,287 examples, of which 75 per cent are identified as species (6,340 species are registered in the collection, representing more than 90 per cent of the plants in the country); and a malacological collection of 74,483 examples, of which 47 per cent are identified as species (INBio, 2002). The examples are stored at the National Biodiversity Institute which also makes the information available over the Internet or through the Global Biodiversity Information Network (CONABIO, 2003b). The general field of environmental policies is another new area where action is promoted on monitoring specific themes. The World Resources Institute (WRI), in collaboration with other NGOs and research centres, has developed a Global Access Initiative , a coalition of public interest groups that promote national compliance with commitments on access to information, participation and justice in environmental decisionmaking. It uses the same methodology to establish indicators, seeks participation by more groups to evaluate government action, and measures the development and application of legal frameworks on the various subjects. In Latin America and the Caribbean the project has re-

sulted in reports being prepared in Chile and in Mexico, highlighting advances in the development and implementation of legal frameworks and making suggestions for more participation and better access to information (WRI, 2002). Following a similar direction, the GEF recently approved the Citizen Environmental Project for Latin America and the Caribbean, under the auspices of UNEP. Within the framework of a training process on environmental rights and responsibilities, the project seeks to report on four basic themes: biodiversity, the ozone layer, climate change and international waters. Six networks participate in the project: the Latin American Parliament (PARLATINO), Consumers International, the International Local Authorities Union (ILAU), the World Conservation Union (IUCN), the World Association of Community Radio Broadcasters (AMARC) and the Latin American Council of Churches (CLAI). The project will be developed in seven pilot countries: Argentina, Chile, Costa Rica, Cuba, Ecuador, Mexico and Peru. It includes activities on the production and adaptation of technical, educational and information material; training and technical assistance for members of the networks; demonstrations in selected municipalities to achieve greater public impact; and the publication of all experiences resulting from the project. As well as these information systems, the region has made advances in recognizing the right of citizens to be informed on projects that might affect them. For example, in the case of the Solid Waste Project of the Organization of Eastern Caribbean States (OECS) in Grenada, information on the planning process to install a landfill was only made public at the last minute. Various groups opposed its location because the site was a critical habitat for the Grenada dove (Leptotila wellsi), the national bird, so that those who proposed the project had to find an alternative site for the landfill. The delay in the project could have been avoided if the information had been made available from the beginning (OAS, 2001). A comprehensive study of the environmental situation in general, designed for decision-making, is more recent than the monitoring of specific subjects. Particularly in the past decade, with a significant impulse given by the Rio Summit in 1992, different initiatives have been put forward to prepare wide-ranging environmental reports, both regionally and nationally. Since 1999, UNEP and various international agencies have been promoting the preparation of comprehensive environmental assessments from global to sectoral level, following the GEO approach (see Introduction to this publication). Other countries prepare these reports on the initiative of national government institutions. The Internet - and particularly e-mail, continue to gain importance as tools for the dissemination of information, for various reasons. First of all, they are relatively accessible media that cost little and can reach a

In October 2001, the Forum of Ministers of the Environment of Latin America and the Caribbean, at its 12th meeting, promised to review the work being done at national, regional and global level on environmental indicators and sustainable development. Special mention should be made of the work of the Sustainable Development Commission in specifying a focal point in each country to establish a network of experts to use the analysis to:

develop a strategy so that countries in the region may adopt sustainability indicators to be shared at the Global Sustainable Development Summit;

Principal challenges Countries in the region must improve the quality of international environmental information and make it more uniform so that it can be used as a permanent component of more sectors’ environmental policies. They must provide up-to-date environmental information to the public on how environmental authorities render accounts. A coordinated system is desirable to compare data between countries, because the generation and exchange of environmental information in

They have also played an important part in building local development agendas and generating or facilitating participation in preparing, implementing and monitoring compliance with environmental policies. Universities, government agencies, the private sector and international organisations often participate in these programmes.

general, and on successful experiences in particular, continue to be key factors in the promotion of new environmental activities.

Environmental training and education Training and education together make up a strategic transversal component of environmental policies. In Latin America and the Caribbean they have been developed on different levels: formally, from basic to postgraduate education and, informally, by means of programmes and activities developed by governments, NGOs, private, academic and scientific sectors, and international and multilateral organisations, jointly or individually, or by setting up networks or other collaborative efforts. Environmental education and training processes play an essential role in promoting participation by all local, national and regional environmental decision-making sectors. The new approaches consider the complexity of the problem of the environment, different cultural identities and integration with other areas, such as the economy. Little research is done on environmental themes, and although governments are aware of its importance they do not always provide the necessary resources. Some have opted for developing collaborative financing efforts with other interested sectors, such as industry. The public can become aware of environmental concerns if they receive basic training so they can understand the ecosystems in which they live, and learn how to make use of the tools and authorities that will allow them to take part in environmental decision-making. NGOs play an essential role here: they can facilitate decision-making by acting as channels for information required by communities to government authori-

Chapter 3: Policy responses to environmental problems

However, in spite of efforts that go back to the 1970s, the academic sector, responsible for training scientists and technicians, has been slow to adopt this principle which has been accepted in varying degrees in the different countries. Advances are seen in graduate and postgraduate studies with an interdisciplinary approach, and with more opportunities to train in environmental areas. Agenda 21 brought commitments from governments to develop environmental policies and strategies, including action on environmental education. Many governments created environmental educational management units; others even approved laws on environmental education, as Brazil did in 1999. In almost the whole region, a series of environmental networks has permitted the advance of environmental and development projects, cross-sectoral, interdisciplinary and international strategic alliances, more efficient fund raising, and keeping the training of their members up to date with new developments. Within this framework, environmental educational projects have been developed in basic and semi-diversified education, and there are even alliances between Ministries of Education and the Environment in countries such as Colombia, Venezuela, Brazil and Bolivia. Innovative pedagogical models including transversal environmental teaching in the school curricula have been applied in El Salvador and Cuba, among other countries, (Leff and others, 2002). The Argentinean Educational Workers Confederation (CTERA), with almost 300,000 unionised teachers, has formed an environmental alliance with other social and organisational stakeholders. Its objective is to exert a positive influence in solving socio-environmental conflicts and promoting the construction of an environmental curriculum for educational systems. A parliamentary commission in Argentina recently approved a proposal to include environmental education in the education system (Cámara de Diputados de Argentina, 2002). At university level, in Brazil the agency that assesses postgraduate courses (CAPES) and has links to the Ministry of Education registered a significant advance in the number of multidisciplinary courses on the environment and development: between 1994 and 2002 the number of Master’s degrees awarded rose from 28 to 56 while doctorates increased from 11 to 19. The Environment and Development PhD of the Paraná Federal University was a pioneer experiment on theory and methodology, backed by the UNESCO Chair of Sustainable De-

Environment Outlook

velopment and by UNEP (Febres-Cordero, 2002). In Argentina in 1998 a postgraduate course on environmental education was inaugurated and at present, through an agreement between CTERA and the National University of Comahue, a specialised degree course on Environmental Education for Sustainable Development has been taught since 2000; it was extended to different campuses in other parts of the country in 2002 (Galano, 2002). In Costa Rica, efforts to include the environment in higher education began in 1973 with the creation of the country’s first degree course on environmental sciences (also one of the first in the region - FernándezGonzález, 1998). By 1998 Costa Rican state universities had 35 degree courses, 10 or more with an environmental content, and there are now various Master’s programmes with this approach. Among recent non-formal environmental training initiatives, mention should be made of the Chilean experience with the programme on Industry and the Environment developed by ECOPAT, the National Professional Training Institute of the Manufacturing Promotion Society, the Ministry of Education and the National Environmental Commission of Chile (CONAMA). The programme seeks to raise the level of awareness, and provides training on environmental responsibility, sustainable development, freshwater, energy, soils, urban environment, clean production and other key environmental and social aspects. It is meant for teachers in technical schools and industry – metals, electronics, chemical and motor vehicles – and professional trainers (OAS, 2001). Another training example, this time at regional level, is the Education and Communications Commission of the IUCN which, by means of meetings and publications, focuses its efforts on disseminating information on environmental education experiences (IUCN, 2003).

219

Another non-formal environmental education mechanism is the development of local, national and regional workshops attended by representatives of government and non-governmental sectors. The motive may be the preparation of a management plan for a protected area, the construction of a local environment and development agenda, the discussion of a decision-making project, the dissemination of information about participatory methods, agreement on the formulation of a policy on the eradication of invading species and the management of a basin, a ministerial declaration on the importance of water, and so on.

Principal challenges Environmental training and development should be considered permanent and transversal processes in any environmental policy or strategy, whether local, national or regional, but more applied research is needed in all environmental areas. National policies must consider environmental education as a foundation for public participation by all social sectors. There is a need to strengthen interdisciplinary work, actively include the mass communications media and recognize the cultural diversity of countries. Universities must continue training professionals, scientists and technicians according to the new paradigms of sustainable development, and set training priorities jointly with government and civil society. Science and technology must undertake more basic applied research on sustainable production and eliminating poverty.

Regional development scenarios

T

his chapter contains three descriptions or scenarios of how the region might evolve in the period 2002-2032. These plausible scenarios are the result of the interaction between the driving forces of development and economic, political, social and environmental trends as well as decisions taken during that period by authorities, business and citizens.

The construction of each scenario presupposes specific development conditions. These depend on how much weight governments and citizens give to the problems of society and to the roles of government and the market in allocating resources. They also depend on the future outlook and on social, economic and ecological sustainability. To help decision-makers understand the problem, only three scenarios are included, although others could have been defined. These are: unregulated market scenario (deregulation), reforms scenario (moderate intervention) and great transitions scenario (sustainability). The current situation reflects elements of each of these three scenarios.

Preparing scenarios as a long-term environmental evaluation instrument Significant methodological challenges are faced by GEO in making long-term assessments of environmental and socio-economic themes.1 Many of the customary techniques such as trend analysis and mathematical models do not work when considering decades rather than years or months. From available data it is impossible precisely to extrapolate what will happen over the next three decades. Amongst other factors, lack of information makes it difficult to be precise. Other factors that cause problems are the vagaries of complex systems and the subjectivity of human decisions, particularly future ones. Scenarios allow us to examine different combinations of driving forces, including doubts that arise along the way, and consequences of the decisions we do or do not take. A scenario is a tale told with words and numbers; it may help decision-makers to direct events along sustainable paths and avoid those that could mean adverse consequences for development, equity and sustainability. To be relevant, scenarios must be prepared rigorously, meticulously and creatively. Furthermore, they should be designed using plausible criteria, internal coherence and sustainability. They should be based on science – that is, our understanding of historic patterns, present conditions and physical and social processes – and imagination. They might shed light on existing links between subjects such as the relationship between global and regional development.

Chapter 4: Regional development scenarios

The formulation of scenarios begins with the assessment of conditions and the selection of parameters. While some regions share common features — demographic and economic patterns, state of the environment, social dimensions –others have unique conditions (political and legal institutions, cultures, values) which make it necessary to prepare descriptions reflecting these, as well as their structures and social tensions. To develop scenarios the usual steps taken include are to: 1. define the meanings of the boundary of analysis: spatial (world, regional, sub-regional), thematic (subjects and sectors to be covered) and temporal. 2. describe the present state including a range of economic, demographic, environmental, and institutional dimensions. 3. describe the driving forces and important trends influencing the system. 4. make the narrative present the argument by which the stories unfold (quantitative indicators are often used to illustrate some aspects). 5. present an image of the future that depicts conditions in one or more periods. Some scenarios are future projections of events that might arise, given present conditions. Others are retrospective: they start by identifying a future image with previously set goals, and then build plausible paths to reach them. Images of the future may be seen as either attractive or repellent, thus influencing human actions and de-

(continuation) cisions. Negative images play an important part, creating awareness and encouraging efforts to avoid unwanted outcomes by redirecting the system’s evolution. Unexpected and extreme events can affect world development: the collapse of climate systems, a world war, availability of cheap energy from nuclear fusion, a serious natural disaster, a world epidemic. It is, however, impossible to calculate all probabilities or possibilities. From the sustainable development point of view, one recommendation might be to reduce as far as possible the social and environmental vulnerability of systems to adverse happenings, and to improve their capacity to recover from them. Scenarios can be explained by multiple spatial levels, although some aspects only appear clearly at specific spatial levels. For example, a global panorama must be explored to be Able to examine worldwide economic, cultural, demographic and environmental phenomena. A regional outlook is needed to analyse problems that include acid rain, pollution of international waters or the degradation of systems shared by two or more countries, and certain migratory patterns. On

In the unregulated market scenario, emphasis is on the market and the trend is towards full liberalisation and globalisation with minimum controls and a very limited state role. This means that regulatory instruments, both direct and indirect, lose their force and even control instruments, so popular at the end of the 20th century, are brought into question. Without direct and indirect regulatory instruments, neither social nor environmental costs are taken into account by the productive sector or by industry. Market distortions or the asymmetries that accompany monopolistic competition are ignored. Equity is only a rhetorical concept and, in practice, the initiatives set up in the early part of the 21st century to improve income and wealth distribution are abandoned. In the reforms scenario emphasis is on regulation by means of moderate market intervention. It presupposes a certain institutional progress and the development of policies and instruments designed to correct market imperfections, promote equity and, when decisions are made, to take account of the social and environmental costs of consumption and production. Nevertheless, government actions include few attempts to integrate social and environmental variables. There has been a heightening of public awareness about these questions, but values such as social solidarity and care

the other hand, a national outlook might throw light on many questions of policy, trade patterns and security, while to evaluate changes in land use, biodiversity and pollution, a local vision is required. These different spatial scales help perception and understanding by opening complementary windows of analysis. In a world increasingly connected, regional and global scenarios must evolve through an interactive and interconnected process. All studies based on scenarios must reduce the enormous number of possibilities to a few stylised arguments. Contrasting considerations must be balanced. On the one hand, analytical rigour demands that many alternatives be taken into account. On the other, brevity and clarity are needed to communicate with a vast audience of individuals who have no special knowledge of the subject. The scenarios are not simulation models. Certain things cannot be measured, such as cultural influences, values, behaviour and institutions. Quantitative analysis offers a degree of structure, discipline and rigour, while narrative may bring wealth and discernment. The trick is to find the right balance.

for the environment are still not a part of public morality. The basic premise of this scenario is the political and social feasibility of linking market growth with a set of sustainability policies aimed at eradicating extreme poverty and environmental degradation. Finally, in the great transitions scenario, development sustainability predominates. It represents an advanced state of society, a new path towards sustainable development that integrates economic, social and ecological dimensions, is understood by citizens, business and governments, and is actively adopted. This scenario is strong on social solidarity and criteria about interand intragenerational equity and shows a growing concern for the implications of environmental deterioration. It presupposes much more public awareness; social solidarity and environmental concern are rooted in public morality. When preparing work on scenarios for the GEO-3 global report a fourth security first hypothesis was considered. This depicted a world of great disparities where socio-economic and environmental tensions result in inequalities and conflicts. In GEO LAC 2003, this fourth hypothesis is considered as part of the unregulated market scenario and, to a lesser extent, as part of the reforms scenario.

In any event, a linear view should not be taken of processes which, if they begin now, will eventually become a path leading to 2032. The definitions given here are not of three independent development paths. They intersect or diverge when choices have to be made and when this vision of the future should lead to the right decisions. The scenarios help us navigate towards our desired destinations. The scenarios are defined by the forces which, according to present trends, determine the paths to development. The main ones considered here are associated with the economy, technology, demography, society, culture, governance and the environment – all factors analysed in earlier chapters. These forces are grouped into two sections within each scenario. The first section, the general concept, considers trends in economics, technology, demography and migrations, the socio-cultural dimension and the state of governance. The second section, on ecology, synthesises environmental trends. In statistical calculations developed to prepare the unregulated market and the reforms scenarios (Raskin and Kemp-Benedict, 2002), 1995 is taken as the base year. Projections were made for two periods, one medium term (to 2015) and the other more long term (to 2032). The data for these two scenarios are presented in the following table and analysed in later sections. To

prepare the great transitions scenario, experts’ criteria were used.

Unregulated market scenario General context The main driving forces of world development at the end of the 20th century continue to dominate during the early decades of the present century without great interruptions, changes in international values or other structural ruptures. Worldwide, there is more economic and cultural integration, while regional and subregional agreements continue along the same lines with a tendency to distance themselves from patterns of sustainable development. In the economic sector, regional and world economies both show a large degree of integration, with the United States taking the lead in the principal regional and world economic organisations. The relative success of the European Union (with its new common currency, the euro) and the economic takeoff in other regions and countries such as China, are neutralised to a great extent by US economic and military dominance. Internationalisation continues and is catalysed by free trade agreements, increasingly deregulated trade and financial flows, and advances in information tech-

nologies. Highly volatile capital flows and a growing dominance of the world economy by transnational companies brings considerable instability. Competitive markets and private investment are still thought of as the driving forces of economic growth and wealth distribution. The regional gross domestic product (GDP) practically doubles by 2015, and triples by 2032. Important growth is expected in the service sector until it reaches two-thirds of the total GDP. The agricultural GDP is re-

duced by at least half while the industrial sector will show only a slight decrease. The GDP per inhabitant will grow by half by 2015 and double by 2032. When the Free Trade Area of the Americas (FTAA) is set up in 2005, a hemispheric economic bloc, dominated by the United States, is consolidated. In this context, sub-regional integration blocs such as the Southern Common Market (MERCOSUR), the Caribbean Community (CARICOM), the Central American Common Market, the Andean Community of Nations (CAN) and

others, tend to progressively weaken and lose importance. Sub-regional integration, however, will be facilitated by physical integration agreements and the construction of large infrastructure projects that connect neighbouring countries. Although some countries in the region still set their sights on industrial countries’ production and consumption patterns, because of differences in the region’s economies emphasis should be placed on sub-regional peculiarities. Nevertheless, most countries follow a flimsy and unstable growth path and there is an evident lack of an export dynamism. Advances in the technology sector increase inequality as the gap between countries widens with fewer investments in research and development, and a reduced regional capacity to take advantage of new knowledge. This gap is also reflected nationally between those with access to the new knowledge and the majority without such access. Although biotechnology and information technologies are of growing regional importance in agriculture, the pharmaceutical industry and human health, transnational corporations are the principal beneficiaries. Access to the genetic wealth of countries with most biological species becomes increasingly controlled by those corporations and local residents are excluded. Environmental standards (involving the whole life cycle of goods and services) adopted during the first years of the 21st century become general, but only weak attempts are made by governments, business and citisens to apply them. Prices do not include environmental costs and, in the first 30 years of the 21st century, continue to be consumers’ main concern. Average population growth projections are met and unplanned urbanisation continues. Over and above subregional differences, the region’s great demographic expansion has ended and by 2032 population growth has stabilised; nevertheless, the total population increases from 480 million in 1995 to 631 million in 2015 and 736 million in 2032. The urban proportion of the population rises from 74 per cent in 1995 to 81 per cent in 2015 and 86 per cent in 2032, while the total urban population grows by 44 per cent by 2015 and 79 per cent by 2032. Both within and outside the region there is more rural migration to cities and between countries, mainly to North America. Large infrastructure projects built in scarcely populated areas, basically with a view to regional integration, induce spontaneous migration of people seeking access to land, a process often stimulated, as in the past, by governments and by land speculators. This is mostly due to socio-economic conditions, but is increasingly aggravated by environmental degradation in rural areas, particularly as a consequence of

·

Chapter 4: Regional development scenarios

desertification, which is causing loss of productivity, and finally driving farmers off the land. In the socio-cultural sector, by 2032 the 1995 levels of inequality remain almost unchanged. Poverty continues to grow in developing countries, with increasing signs of inequality between countries and within them. Not everyone has access to education, employment and social benefits, and this helps to maintain or widen the economic gap. The region continues to have the world’s most inequitable patterns of income and wealth distribution. By 2032, there is a notable expansion of cultures and they are becoming more uniform, with consumerism and individualism prevailing over social solidarity and traditional values. While indigenous cultures persist, large segments of society continue to be unaware of them. This weakens social cohesion and – in the opinion of experts – the benefits of their lifestyles are underestimated: traditional environmental management systems and patterns of consumption, shown to have been sustainable in the past and which, in the first decades of the 21st century, could continue to be so. As to governance, the democratic model of the 1990s persists but is much influenced by the economy that does not reverse the pattern of unemployment and poverty. Protest movements expand both nationally and worldwide, but are soon neutralised. The development of civil society organisations, as part of national decision making, is interrupted and tends to weaken. In the absence of medium- and long-term plans, and since market mechanisms are given free rein, reactive policies prevail in all areas of administration, especially in the social and environmental sectors.

Environmental effects Environmental degradation increases as national and international environmental management systems are restricted and regulation, both direct and indirect, is minimised. Loss of biodiversity, toxic chemical waste accumulation, deforestation, desertification and climate change worsen. Contamination or extraction, a consequence of the growing demand for land, water and energy sources, puts increasing pressure on natural resources. In general, competition for key natural resources increases and expands beyond national borders. It will be easier to understand how the environment evolves by looking at the moderate intervention (reforms) scenario (see box on page 235). It shows that environmental pressure rises at rates between two and four times greater than population growth. The exceptions are deforestation, which continues to increase, but more slowly, and the domestic use of biomass, which is reduced.

Environment Outlook

The ambitious objectives of Agenda 21 (Earth Summit, 1992) and of environmental conventions, again considered to some extent at the Summit on Sustainable Development in Johannesburg (2002), continue to be essentially rhetorical. National development sustainability initiatives are launched but the efforts are few and isolated. The same is true of the initiatives, many converted into action plans, emerging from numerous sub-regional and regional conferences and fora, and from bilateral and multilateral agreements. Action on the environment is concentrated locally with no significant changes in patterns of conduct. The political impulse towards sustainable development enters a global exhaustion phase. Environmental policies react, correct or adapt, ie they continue to be partial, inadequate and sporadic instead of coordinated, integrated and sustained. During the first two decades of the 21st century, agriculture continues its vigorous expansion at the expense of native forests. More agricultural land, particularly of the best quality, is used for export crops. Large transnational infrastructure projects, principally road construction, cause significant negative environmental effects such as growing deforestation which is aggravated by the increase in forest fires. By 2015 the area covered by native forests is reduced by 14 per cent and by 2032 it has fallen by 22 per cent. The area of native forest, which covered only 50 per cent of the total territory in 1995, drops to 39 per cent by 2032. In spite of concern about the proliferation of genetically-modified organisms and the risks of genetic contamination of native species, trade pressures tend to prevail over caution. There is still hardly any organic agriculture. Damage to agricultural soils continues to be a serious problem in 2032. Urbanisation has expanded, mainly at the expense of the best agricultural soils. In the Caribbean small island states, coastal ecosystems and their inhabitants are imperilled by the uncontrolled expansion of coastal settlements, a proliferation of tourist centres, an increased and uncontrolled discharge of waste and a lack of, or failure to apply, firm regulations. At the same time, the dynamics of the unregulated market scenario imply a much more rapid rise in general temperatures than in the other scenarios. Under the same scenario, a lack of investment to adaptation programmes makes people more vulnerable because of a lack of investment to adapt programmes. The continued increase in the number and intensity of natural disasters produces serious social and economic damage to the inhabitants of small islands and their coasts. Urbanisation increases the demand for services, making large segments of society environmentally vulnerable, and accelerating the erosion of social values.

231

Basic services such as health, the supply of drinking water and sanitation also deteriorate, and waste disposal problems intensify. Regional dependence on fossil fuels worsens and the 30 per cent of primary energy requirements they account for rises by half by 2015 and doubles by 2032. This hinders the growth of renewable energy sources, even though uses of such sources will more than double. It is already noticeable how the demand for primary energy increases at a rate higher than that of population growth. Many people in urban areas are still exposed to dangerous pollution levels. At the beginning of the century, negotiations on mitigating and adapting climate change were affected by the decision of the United States government not to ratify the Kyoto Protocol. The Organization for Economic Cooperation and Development (OECD), most of whose members are industrialised countries, does not comply with the Protocol’s objectives for the period 2008-2012. By 2032 the effects of climate change are more evident. Carbon dioxide emissions double by 2015 and triple by 2032. Native forest areas are reduced and their quality worsens due to the expansion of agriculture, forest fires – increasingly numerous and frequent – and their ecosystems’ greater vulnerability. As part of the strategies to respond to climate change, countries in the region face intense pressure and demands to halt deforestation, but without receiving adequate compensation. More species are in danger of extinction due to illegal traffic and the degradation of natural habitats. The pharmaceutical industry, for its own ends, promotes biodiversity conservation in developing countries. Improper appropriation of developing countries’ genetic material and traditional knowledge to generate new patentable chemical and pharmaceutical products continues to be a matter of concern for countries in the region. The need for water has grown and there is more conflict among users as to how it should be used. Supply has decreased as a consequence of pollution and degradation of rivers and aquifers, seasonal shortages, climate change and a drop in groundwater replenishment. The rate of extraction increases more than demographic growth. The population without enough water almost doubles by 2015 and is two-and-a-half times greater by 2032. Water availability in 2032 is hardly two-fifths of the amount Europeans had in 1995. In 2032 multiple aspects of marine and coastal resources identified as a cause for concern at the end of the 20th century have become worse. Governments have concentrated their attention on protecting critical coastal tourism zones and urban residential zones.

Reforms scenario General context There is a drive towards sustainable development. There is also renewed commitment to act and a consensus emerges on the urgent need for policies to ensure environmental sustainability and reduce poverty. Although consumerism persists, people begin to think of nature, equity and solidarity as part of their way of life, and they start to take on an ethical connotation. Nevertheless, there is still emphasis on economic growth, trade liberalisation, privatisation and modernisation. The basic supposition of this scenario is that, by linking such growth with sustainability policies, it is possible to eradicate extreme poverty and halt environmental deterioration. As for the economic sector, global integration continues and so does domination by transnational companies. Large multinational infrastructure projects bring together sub-regional blocs with interests that are fundamentally economic, and that represent a threat to environmental stability in areas until now under little pressure. By 2015 GDP doubles and grows more than twoand-a-half times by 2032. It is important to note that these rates are higher than those projected for the market scenario. Growth is also greater in terms of GDP per inhabitant, which expands by more than half by 2015 and rises by almost two and a half times by 2032. Even so, the reforms scenario shows notable inequality: incomes of the richest fifth of the population are more than 10 times higher than those of the poorest fifth. Following the pattern of OECD countries, the main current of analysis and regional and lower-level decision-making begins to include the objective of a less material-based economy. Governments propose to modernise economies and social welfare structures. Decentralisation of national policies, public spending and investment decisions are considered instruments that can be used to attain sustainable development. International trade maintains its impetus, especially with the overall removal of national barriers. The region increases its competitive advantages and expands its exports to North American Free Trade Agreement (NAFTA) countries and, in general, to markets in the industrialised world. The emergence of a stronger regional identity is a key element to facilitate regional cooperation, as well as to link the region with the rest of the world. Subregional blocs – Central America, CARICOM, the Andean Community and MERCOSUR – become stronger trade and political entities, and expand in a network of ·

policy and economic relations within their own region and with others. Notwithstanding, it must be borne in mind that many commercial interests in the United States conflict with proposals designed to strengthen regional integration. Information technologies and biotechnology prosper, together with the exploitation of each country’s biodiversity. Agricultural technologies are promoted both by governments and private enterprise. Government incentives are given to private sector investors for regional and national research. Society improves its capacity to assimilate information and generate clean productive technologies, although the adaptation of imported technology predominates. Progress is made in appropriating modern and traditional technologies. As to demographic and migratory trends, demographic movements begin to accelerate. Rates of population growth show a marked drop and the population tends to stabilise in the region’s more developed countries. The rate of annual growth in the period 1995-2032 is slightly lower than that shown in the market scenario. Migratory flows from rural to urban areas tend to fall while populations grow in intermediate cities. There is no great difference between the market and reforms scenarios when it comes to the percentage of urban population. International migration continues, both within the region and towards North America — although the number of migrants tends to decrease; socioeconomic development on the one hand in and between countries within in the region, and on the other, between them and the United States and Canada, continues to be unequal. The expansion of migration encourages the establishment of social security agreements within the region and between regions in order to protect each country’s citizens when abroad. In the socio-cultural sector, inequities remain between countries in the region, and between the region and developed countries. OECD countries, and particularly the G-7 (the group of the seven countries with the most dominant world economies), begin to promote specific policies to reduce economic disparities between rich and poor, with a strong commitment to extreme poverty eradication programmes. The distribution of income and wealth improves in most countries in the region. For the first time in history, widespread and effective policies are adopted to end extreme poverty. Besides the above-mentioned improvement in distributing income, women have greater access to the labour market and there are fewer gender inequalities. More women are in high government posts and in the private sector. Also, indigenous cultures and minorities gain more respect and are protected. Indigenous people are formally recognised and some of their traditions in-

cluded in public administration instruments, particularly those concerning health services, education and housing. Nevertheless, social, ethnic and geographic inequality often causes groups that fear for their rights to mobilise against the authorities. Where governance is concerned, governments strengthen national environmental institutions and their commitments to multilateral environmental agreements. As the population becomes aware of the harm human activities can cause the environment and their connection with health and ecosystems, demands are made for more preventive and control measures and for compliance with new policies to ensure the inclusion of environmental costs in productive processes. Civil society is accorded due recognition. Locally, the role of organised civil society is strengthened and it exercises strong pressure on local and national governments to reflect new or strengthened roles. Non-governmental organisations begin to become more vigorously involved in analysis and decision-making processes through mechanisms such as National Sustainable Development Councils, which are also strengthened, as are their local equivalents. A new social vision of development begins to emerge and supersedes earlier approaches based on the market or the state.

Environmental effects Throughout the region the public in general and different social groups in particular are more aware of the environment, which helps to improve environmental protection and reinforce sustainable development concepts. UNEP and other international organisations advocate effective actions for the reduction of poverty as well as sustainable development. The Forum of Ministers of the Environment of Latin America and the Caribbean is strengthened and begins to play a key role in formulating regional and sub-regional policies; it even becomes a mark of reference to define national policies. Sustainable development becomes the central objective of regional and sub-regional organisations (including the sub-regional commercial groups mentioned above, and other multilateral agencies such as the Organization of American States and the United Nations Economic Commission for Latin America and the Caribbean). A larger population exerts increased pressure on natural resources and more raw materials are needed. This is in part offset by appropriate management practices and a set of environmentally-rational technologies, including traditional indigenous knowledge and technologies. A direct effect is that agricultural expansion is halted. International agreements are reached on the environment to substantially reduce the environmental pressure exerted by OECD countries. It is recognised that

233

development and industrialisation processes should continue in developing countries with a view to gradually lessening OECD pressure. Improving natural resources management, adopting policies to confront vulnerability and applying preventive measures, lessens the impact of natural disasters on people and ecosystems. Thus, for example, the vulnerability of coastal areas to disasters of both natural and human origin is reduced thanks to early warning systems in the zones most vulnerable to storms and disasters, and to better management of natural coastal defences such as mangroves and coral reefs. Scenarios are devised to simulate the behaviour of environmental processes, and to help integrate management and monitoring. In addition, systems are put in place to monitor large shared ecosystems. Practically all countries in the region commit themselves to coherent environmental management systems that include direct regulation and economic instruments as well as voluntary agreements with industry, thus improving the efficiency of programmes designed to conserve the environment. The development of markets for environmental services, such as the capture of greenhouse-effect gases, helps to conserve different ecosystems; income (from users) for those who own the resources is generated, and finances different environmental management initiatives. In the energy sector, prices continue to rise as a reflection of the environmental concerns expressed in different regulations. Electricity and natural gas become the main forms of final use energy due to their convenience and flexibility;, coal is abandoned as far as possible by almost all production sectors. Processes that waste a lot of energy and fuel are increasingly displaced by others based on renewable energy sources and more efficient technologies, thus reducing energy consumption. Sustainable agricultural practices that include integrated management techniques and the selective application of biotechnology gradually penetrate most of the region, with markets in Europe and other regions opening up to its agricultural products. Progress is made towards sustainable land management, and large areas deteriorated by development projects are rehabilitated. Rural employment increases by the development of nonagricultural activities that reduce pressure on land and forests. Cities are better planned and organised, so there is less urban environmental pressure. Services are improved in intermediate cities to convert them into alternatives for housing and industry. However, as pointed out earlier, urban population growth is almost the same in the reforms and market scenarios. Plans to regulate urban areas are consolidated and, to some degree, they favour the relocation of industries. Domestic and

industrial waste management is noticeably improved by better collection, transport, disposal and recycling systems, as well as better programmes to clean domestic and industrial sewage. Air pollution in urban areas begins to abate because more public transport is available and better use is made of it, and by advances in controlling the main pollutants, although pollution continues to be a problem in megacities. Climate change is the most serious unsolved environmental problem in the three decades from 2002 to 2032. The Intergovernmental Panel on Climate Change (IPCC) submits new reports that stress serious concerns about the integrity of the climate system. The Framework Convention on Climate Change, the Kyoto Protocol – which in this scenario is finally ratified by the United States – is the main instrument for making advances in reducing greenhouse gas emissions. Nevertheless, the relatively long delay in the climate system’s response means that patterns of climate change continue with very small differences between the scenarios. In the Caribbean small island states and other particularly vulnerable regions, disasters continue to be a serious problem that causes loss of life and material damage. While more investment is made in early warning systems and adaptation measures under this scenario, it is not enough to prevent the region’s poor suffering economically and socially from disasters. These emissions are substantially reduced in the region as a consequence of changes in land use. There are fewer forest fires, fundamentally because of less deforestation, better management of forest resources and improved prevention and control. While a certain degree of deforestation was expected – the native forests decreased in area by 12 per cent in

the period 1995-2032 – logging of primary forests tends to be restricted by sustainable use, promoted by market pressure with increasing demands for certification of companies and of forest products within the framework of recognised international programmes. In addition, traditional communities that depend on non-timber forest products find market niches, thus helping to consolidate their activities by making it easier to conserve native forests. Biodiversity is conserved within the framework of critical ecosystems (including coral reefs), and by greater access to information, which comes out of monitoring programmes. Progress on international genetic resources agreements, such as the Convention on Biological Diversity and the Cartagena Protocol on Biosafety, stimulate countries’ interest in conserving biodiversity-rich ecosystems. Technological and financial assistance also increases biodiversity conservation. Continental waters –surface and underground– are assessed as a critical resource. Projects have been launched within the framework of appropriate use mechanisms and rigorous normative programmes, to make water storage, transport, use and recycling more efficient. Water policies are enforced that take into account its availability, existing water balances and associated ecological and aesthetic values. Water quality programmes are established to avoid deterioration caused by its different uses, and are designed to restore degraded water courses and bodies of water. At the same time, effective policies are adopted to increase availability of water from alternative sources such as the reuse of sewage water and desalinisation of salt and sea water. In general, integrated watershed management is helping to make the use of appropriate management practices the general standard.

Comparative analysis of relevant environmental variables in the market and reforms scenarios, 1995-2032 A comparison between relevant environmental variables in the market and reforms scenarios shows important, especially long-term, improvements in the second scenario. The most significant impact of the reforms scenario is seen in an absolute reduction (13 per cent) in toxic residues. This reduction is dramatic relative to population growth, since it reflects a drop of 40 per cent in the generation of toxic waste per inhabitant. It will have consequences of tremendous importance on the health of the region's population. Stabilizing the consumption of nitrogenous fertilizers from 2015 is another notable product of the reforms scenario. It is a consequence of a stabilisation of agricultural production which, however, does not affect food security levels. In effect, it takes place in the context of better Regional population Primary energy requirements income distribution and, therefore, (millions of inhabitants) (exajoules) 800 70 of consumption capacity.

The other environmental problems selected continue to get worse in both scenarios, although in every case to a lesser extent in the reforms scenario, especially over the long term. For example, while the level of carbon dioxide emissions practically triples by 2032 in the reforms scenario, there is a trend towards a significantly smaller increase than in the market scenario. The area of native forests decreases by 12 per cent by 2032 in the reforms scenario compared to 22 per cent in the market scenario.

The two environmental variables where the smaller difference is seen between the market and reforms scenarios are primary energy requirements and population growth. Even so, the increase in fossil fuel (coal and petroleum) primary energy is noticeably less in the reforms scenario (except in the case of natural gas). This is reflected in a lower relative worsening in the reforms scenario as to carbon dioxide and sulphur oxide emissions. On the other hand, in the reforms scenario primary energy generated by clean (hydroelectricity and renewable) sources grows at much greater rates (up to four times) than in the market scenario.

Great transitions scenario General Context Governments, business, social organisations and citizens have all understood the need to look for a new path to sustainable development, and one is being gradually followed. Because public awareness very soon exerts pressure in favour of reforms, more concrete action is taken. Sustainable development strategies are based on a broad range of instruments (plans, programmes and projects; social investment and focussed public spending; norms and legal texts, taxes and subsidies, voluntary agreements and public-private mechanisms). Social investment and local development policies are among the instruments meant to improve the quality of life and social equality with respect to inhabitants’ ages and where they live. Attempts are also made to restore damaged ecosystems, resources and environmental functions (restoration of soils, reforestation, cleaning rivers and lakes), to prevent environmental deterioration, and to disseminate information on conservationist technologies and practices. Worldwide, there is a gradual change from consumerism, materialism, out-and-out competition and individualism towards solidarity, thus increasing attention to the problem of the environment and to the inequalities that predominated at the beginning of the 21st century. A consensus emerges, a paradigm concerning the need for a new style of development, now known as sustainable, as opposed to traditional development with emphasis on expanding and increasingly less regulated and globalised markets. This is expressed in the growing transfer of development management responsibilities from governments to transnational corporations, which will later prove to be both inefficient and unwelcome. As for the economic sector, strong communication and trade links are developed between countries in the region and the result is a close network of interactions with other regions in the developing world from the South-South point of view. The region considerably reduces its dependence on exporting raw materials, and develops competitive advantages based on incorporating technical progress into production by using practices that are rigorously framed in environmental normative contexts and are based on fair compensation for work done. This encourages authentic competition, as opposed to spurious competitive practices that depend on lax environmental and social regulations, and on labour exploitation. The growth and consolidation of a large middle class leads to the expansion of regional markets for primary and secondary products – which also occurs in other developing regions – and stimulates trade. Production with value added becomes a sustainability strategy. Improvements in investments and qual·

Chapter 4: Regional development scenarios

ity of life bring demands from consumers for better environmental quality. There is an evolution towards new patterns of consumption that approach those in industrialised countries and modify consumers’ preferences as they seek goods produced by environmentally-sustainable processes. The market continues to be the main mechanism influencing production. The basic difference between this and orthodox development styles, besides redistributive policies aimed at the poorest sectors of the population and marginalised zones, is that prices include — to a greater extent and in more depth than in the other scenarios – external social and environmental costs, basically by the use of economic instruments or market programmes. In the technology sector, innovation responds to the new demand for sustainability and efficiency. Information and communication technologies advance and expand geographically with government and economic activities becoming decentralised. Technological efforts are intended, above all, to evaluate the relevance of foreign technologies and adapt them to local needs while also developing and strengthening endogenous skills capable of producing technologies appropriate to the region. This is an incentive for sustainable economic growth and helps to increase exports with more value added. Biotechnology makes great strides in the region and research into it is promoted. Access to genetic wealth is regulated, taking account of the interests of countries and local residents. New technologies and traditional knowledge are directed at solving problems of poverty, and offer significant opportunities for sustainable agriculture. Traditional medicine is revitalised. With respect to demographic and migratory trends, demographic movements are accelerated. By 2015 there is an obvious reduction in inequalities, with more and broader social participation. The rate of population growth quickly declines and, as far as analyses show, leads to a drop in population. Family sise is reduced and stabilised while life expectancy continues to rise. In the socio-cultural sector, social and economic renovation is translated into a spiral of rapid positive change, as patterns of distribution, social structures and ethical values associated with the change of paradigm become general. Distribution policies relating to income and wealth are accepted and adopted, thereby stimulating new employment opportunities and a drastic reduction in poverty. Aside from national progress in wealth and income distribution, the gap between the developed and developing world begins to narrow. New values and visions of the world emerge within global society and indigenous, religious and local cultures are re-assessed, while ideological, religious and ethnic tensions tend to dissipate.

Environment Outlook

Access to basic services such as health, water, sanitation, housing and education significantly improves with time. Poor, handicapped and marginalised minorities are favoured so that there is more equality based on participatory and decentralised schemes. By 2032 pockets of poverty persist and occasional geopolitical conflicts and tensions arise about the environment, while natural resources require coordinated action. However, mechanisms are now available to deal with these problems. Great achievements have been made as to human development, solidarity and ecological restoration. In terms of governance, the new development style depends on the expansion of democracy with citizen participation in all spheres, from public management of executive power to mechanisms of participation in the legislative system, in justice and in municipal management. There is a multiplicity of citizens’ organisations, a process favoured by improvements in formal education and training opportunities. These are times of consensus as opposed to confrontation. Regional cooperation hinges upon the strengthened role and status of sub-regional and regional schemes, multilateral agreements (governmental and non-governmental) and a growing participation of various organisations that represent civil society, including private enterprise, all with their own sub-regional or regional convening authorities. Countries in the Caribbean and other sub-regions begin a process of convergence and coordination that transforms them into a solid bloc of countries, increasing their power to negotiate and become better placed in the world economy. On the global scale, governance evolves towards a system in which regions and communities have considerable control over socio-economic decisions and approaches to environmental preservation. Global governance hinges on a rejuvenated United Nations Organization, restructured to express the new sustainability paradigm of diversity through world unity.

With a new emphasis on organic agriculture and ecoefficiency, production becomes increasingly less polluting. State regulation and voluntary agreements make clean production the standard. Industrial and domestic wastes are reduced to a minimum and, through recycling and re-use, they become valuable inputs for new productive processes. Fewer diseases are associated with acute or chronic exposure to chemical pollutants. Integrated planning becomes a central instrument for managing river basins and urban, coastal and lake zones and — together with direct regulations and economic instruments – improves management and environmental conditions in cities and rural areas, facilitating the sustainable conservation of renewable natural resources. Conservation schemes and rational exploitation are consolidated according to each country’s culture and traditions. This is made possible by requiring property rights to be included and by taking advantage of resources, as well as by consolidating communal forms of exploitation. In the energy sector, renewable sources and energy efficiency are promoted, and advances made in regional energy integration. Technology for efficient energy transport systems helps to reduce urban air pollution and solve serious traffic congestion problems in large cities. Urban and rural planning develops instruments to improve the allocation of land for competitive uses, bearing in mind long-term alternatives. Great efforts are made to recover degraded land, while soil conservation is already a criterion in agricultural decisions and a clear long-term production factor, Agricultural production is increasingly based on the principles of agro-ecology that began to be promoted during the last three decades of the 20th century. Cities begin to become sustainable. A new metropolitan vision stimulates a restructuring of urban life around integrated patterns to locate settlements, placing work centres and commercial and entertainment

Environmental effects Environmental quality improves on all fronts, and regional and sub-regional agreements consider the growing concerns of communities and governments about borders, shared ecosystems and natural resources, particularly in the case of international watersheds, border forests and coastal zones. The elimination of hazardous toxic marine and land wastes is one of the matters on which joint action is taken. As a consequence of the management and products certification framework to which they must adhere, corporations (mainly for competitive reasons) assume responsibility for the whole life cycle of their products, from extraction of the raw material, through processing, to the elimination of the residues of production and consumption.

More effective use is made of biodiversity (both marine and land) and evaluations are more realistic, making it possible to reduce the number of endangered species. Assessing biodiversity from scientific knowledge and traditional wisdom allows an increase in the number of species available for food and pharmaceuticals. New marine and land areas are included in national protected zones; these are dedicated to biodiversity conservation, and also provide environmental services. Fresh water resources are used rationally; management of watersheds and lakes is integrated, and all stakeholders participate in administering them. There is more water available per inhabitant, and fewer conflicts between users as to its use. As water and rivers are cleaned, progress is made in improving the condition of aquatic and land ecosystems on river banks and zones adjacent to rivers and lakes, and in recovering such courses and bodies of water for the purpose of productive and recreational activities.

activities close to living areas. The concept of townships within cities ideally balances a human scale with the intensity of cosmopolitan culture. Others find life in scattered small towns, remote areas and the countryside attractive, as communications and information technology allows them increasingly to decentralise their activities. There are no substantial differences between rural and urban areas as to income and access to services (education, health, electricity, and communications). Because of the long delay in the climate system’s response to changes in emissions, patterns of climate change and their consequences in terms of frequency and number of disasters does not show significant variations. However, under the great transitions scenario multiple measures are developed to reduce vulnerability, including the construction of dams, early warning systems, land use zoning and the integrated management of water basins. These have a significant impact and improve living conditions for the region’s vulnerable populations, especially in the small islands of the Caribbean. Greenhouse gas emissions decrease significantly due, fundamentally, to significant reduction of deforestation and forest fires. There is an almost total halt to illegal deforestation after compliance with a set of direct and indirect regulations is ensured. Non-timber forest products are valued and recognised as belonging to indigenous forest communities, which helps to preserve forest ecosystems. ·

Chapter 4: Regional development scenarios

There are evident improvements in the quality and health of coastal ecosystems, including coral reefs. The establishment of marine parks as well as the effective management of marine and coastal resources make a significant contribution to sustainability and the generation of national wealth.

Conclusions As shown in Chapter 2, the main environmental deterioration processes facing the region are: · · · · · · · ·

Land degradation/desertification Deforestation Loss of biodiversity Air pollution Worsening of water stress Uncontrolled urban expansion Pollution of seas and coasts Vulnerability to extreme natural events.

A weighted ordinal scale was used by a group of experts from the network of centres collaborating with the GEO project in Latin America and the Caribbean. This classified the rate of deterioration under each of these headings, taking account of projections identified for the unregulated market and reforms scenarios, as well as a more qualitative assessment of the great transitions scenario. The result of this classification is shown in the table below. The rate of advance of environmental deterioration was analysed on two levels: according to the set of environmental problems in each scenario, and to the situation of each problem in the three scenarios. On the first level, each scenario was considered in isolation, and the rate of deterioration of the environmental prob-

lems identified observed. In the opinion of the experts, the reforms scenario suggests a rate of environmental deterioration three times greater than the great transitions scenario, and the unregulated market scenario shows a rate almost four times greater. A comparison was also made of the evolution of each problem according to the different scenarios. This analysis reveals that the reforms and sustainability (great transitions) scenarios present a progressive and notable improvement in the rate of deforestation, biodiversity loss, uncontrolled urban expansion and pollution of seas and coasts. However, some environmental problems show more resistance to change, not only in the reforms scenario (the degradation of land and water stress) but also, although to a lesser extent, in the sustainability scenario (air pollution and vulnerability to extreme natural events). In all cases, even in the great transitions scenario, there is moderate deterioration. In general, it can be concluded that the unregulated market scenario would be a dangerous legacy for the next three decades, and predicts a rapid worsening of the environment. The increasing pressure on ecosystems caused by a combination of the effects of population growth, the scale of the economy and the exploitation of natural resources, is unsustainable. In addition, the impact on the environment could undermine an essential premise of the unregulated market scenario: uninterrupted economic growth. It would therefore also be incapable of satisfying social and sustainability goals. Absolute poverty persists and the rapid increase in average income, which tends to reduce poverty, is neutralised by the growth of the popu-

lation and the persistence, if not the worsening, of a highly unequal income distribution. The wish to migrate to rich areas is more and more accentuated, as is their resistance to such migration. Inequalities among social groups, countries and subregions could also worsen geopolitical tensions. Economic and social polarisation could affect social cohesion and highlight the fragility of democratic institutions. Pressure on resources and the environment would also intensify national and international tensions, as a result of conflicts over water, regional concentration of petroleum reserves, shortage of land, effects of climate change and loss of biodiversity. All this would reinforce a violent cultural regression. The unregulated market scenario illustrates a situation where the existing large divisions among humanity are accentuated. In effect, the gaps separating the industrialised world from the developing world, which internally divide national societies in Latin America and the Caribbean, would become even wider. It is a matter of differences in quality of life, vulnerability to environmental transformations, styles of management, public and entrepreneurial administration, and patterns of consumption and lifestyles. The reforms (regulated market) scenario, however, shows that the dangers of the first scenario are not inevitable. Technological resources and policy instruments are available to redirect development towards sustainable objectives. Compliance with these goals, in a context of economic growth aimed at the market, sets significant challenges. Nevertheless, the continuous adjustments to the use of social, technological and natural Chapter

resources may have important cumulative effects in the coming decades. Even with the acceptance of the Kyoto Protocol, a degraded natural environment and a growing and unplanned urban environment would be highly vulnerable to climate change with repercussions in the region. Notwithstanding, at the heart of this scenario there remains the doubt as to whether enough political will can be mobilised to support an effort of that magnitude. Besides the required political responses, fundamental changes would have to be made in values and lifestyles. The great transitions scenario (sustainability) contemplates the emergence of a humanist perspective, based on respect for life, equality between and within generations, and social solidarity. This scenario presupposes the existence of enough institutions to meet these goals, as well as an active participation by all sectors of society. This scenario is the only one that envisages a

process to adapt to climate change and a high level of disaster prevention. These scenarios contain important lessons and indications for the region’s decision-makers. The three narratives presented reveal that the most promising economic, political, social and environmental results would be associated with the adoption of comprehensive, equitable and long-term sustainable development policies that involve different social stakeholders. The most negative results would be linked to both the out-and-out application of market formulae and to situations of extreme polarisation, where the elite with the power tends to become more and more separated from the majority of the population.

egional environmental problems, from loss of biodiversity to water contamination, have worsened since the Earth Summit in Rio in 1992. The uneven economic growth in Latin America and the Caribbean has come at a high cost for the environment. Chapter 2 describes how many natural ecosystems have been degraded and some completely destroyed. At the same time over 40 percent of the population of Latin America and the Caribbean live in poverty, and the gap between the rich and poor continues to increase in many countries of the region. Despite this situation, the focus of development continues to be macroeconomic growth. Of the three pillars of sustainable development (social, environmental and economic), social and environmental issues have been relegated to a secondary level in the design and implementation of development policies. To continue along the current path is no longer ecologically viable or socially just. As outlined in Chapter 4, the unregulated market scenario will lead to increasing pressure on the region’s natural resources, both in terms of contamination and extraction. It will also worsen biodiversity loss, deforestation and water contamination, all of which have marked impacts on human health and wellbeing. Such a scenario, in essence a continuation of current patterns of development and regulation, is unsustainable. The patterns are similar at the global level. The world is plagued by increasing poverty and continually-widening environmental, policy, vulnerability and lifestyle divisions between the haves and have-nots all of which threaten sustainable development. They must be ad-

dressed urgently and more successfully than has often been the case in the past. Certain key areas have been identified for global action at all levels to ensure sustainable development. To the forefront are securing equitable access to basic needs, overcoming poverty, reducing excessive consumption by the affluent, reversing the processes that contribute to global warming, reducing the debt burden of developing countries, and ensuring adequate governance structures and funding for the environment. Achieving widely agreed environmental and social goals, such as the UN’s Millennium Development Goals or the goals contained in the Latin American and Caribbean Initiative for Sustainable Development requires dramatic and coordinated actions. Policies based on prevention and adaptation should start now and continue for a number of years. If the countries in Latin America and the Caribbean continue to follow the business-as-usual scenario, the wealth of natural resources that have supported economic and socio-cultural development in the region will be further degraded, reducing the regional potential for growth. Even if we act today, many of the effects of environmentally-relevant policies will not be apparent for many years. Human actions, including policy decisions, take their time to have an impact on the environment . Urgent measures must also be taken to help bring environmental and social considerations from the margins to the heart of decision-making and development. A new ethic for sustainable development is needed, one that discards the existing characteristics that support today’s homogeneous but unequal, hierarchical, exclusive and prodigal civilization. In Latin America and the Caribbean the environmental areas where special attention needs to be directed are: ·

protecting and promoting the sustainable use of priority ecosystems;

·

managing the urbanisation process, and

·

addressing the increasing vulnerability of the region’s population and ecosystems.

Many of the suggestions below are drawn from the regional preparatory process for the World Summit on Sustainable Development and reflected in the document The Sustainability of Development in Latin America and the Caribbean: Challenges and Opportunities (ECLAC and UNEP, 2001). Others come from the GEO process at global and regional levels. The list is by no means exhaustive, but it is designed to promote further debate and lead to concrete action. It points out some of the important areas where urgent policy action is needed, and can be put into place by countries, the region and the international community.

Protecting and promoting the sustainable use of priority ecosystems Forests and associated biodiversity Promoting the sustainable use of the region’s rich biodiversity and forest resources is urgent. The current patterns of timber extraction and forest destruction for agriculture and mining are not economically, environmentally or socially viable when the full costs, including the costs of lost long-term revenues for local communities, are taken into account.

the required financial and technical help for implementation of actions linked to the Convention and activities for application of national policies and programmes;

Suggestions for action: ·

Identify priority forest areas and ecosystems and draw up conservation, natural resource use and sustainable development plans for each of these areas;

·

Increase the funding and capacities of public institutions charged with promoting better enforcement of existing forest laws and regulations;

·

Monitor the process of environmental degradation using technologies such as remote sensing; develop indicators that can be used to measure the rate of degradation of the region’s forests as well as actual progress towards environmental, economic and social stabilisation and improvement of important natural ecosystems;

·

Promote integration and improved collaboration among public and private institutions, including community-based organisations and other civil society groups dealing with forest resources, to encourage effective use of limited financial and human resources for forest management and enforcement activities;

·

Strengthen educational and training programmes for the conservation and sustainable development of forests and associated biodiversity, especially targeting local communities;

·

Promote the establishment of a multinational compensation fund which recognises the environmental services of global benefit produced within individual countries by important natural ecosystems, especially forest, which can be used to finance conservation, sustainable production and restoration measures as a specific way of applying the principle of common but differentiated responsibility;

·

Encourage the international community to respond to the high level of ratification of the Convention on Biodiversity and the ongoing integration of the objectives of the Convention into national sectoral and cross-sectoral policies and programmes by providing

·

Promote synergies and closer coordination among convention secretariats, provide additional earmarked financial resources per agreement and work to strengthen global environmental institutions in order to ensure that conventions and protocols are implemented more effectively, with minimum duplication of effort and maximum conservation impact, and

·

Work for the creation and implementation of national regulatory frameworks to control access to and benefits from genetic resources. Harmonise national biosecurity regulation across the region to help protect countries from unauthorised experimentation, safeguard the region’s endemic species against transgenic contamination and preserve the knowledge, innovations and traditional practices of indigenous communities.

Freshwater resources The reduction in the quality and availability of freshwater resources has begun to have an impact on the development potential of some areas in the region and this will worsen as the demand for water rises.

Suggestions for action: ·

Carry out a comprehensive assessment of the status of freshwater ecosystems (replenishment rates for surface and underground sources, water demand by sector, future trends) to deal with the scarcity of national and subregional data and information for the management of freshwater resources;

·

Strengthen institutional arrangements for integrated water management using an ecosystem approach, by establishing water basin committees involving all stakeholders and developing and implementing management plans at the level of key watershed areas;

Latin America and the Caribbean

·

Hold cross-border dialogues to plan transboundary watershed management and resource use in an effective and sustainable manner;

·

Implement legislations and programmes that encourage the internalisation of all costs related to the supply of water (including ecological services from land– use management and the maintenance and extension of water supply systems) and minimise water losses from the system, by introducing more efficient water supply and treatment technologies, and

·

Develop and implement water conservation plans incorporating a strong educational and awarenessraising component, with the participation of main water consumers (e.g. agriculture, residential, and industry).

Managing the urbanisation process The current trend of urbanisation will continue in the region, even though its rate will slow in the coming years. Pollution control will remain one of the main items on the agenda, as countries attempt to manage their growing urban areas.

Suggestions for action:

Assess the link between urban environmental pollution (water and air) and the resulting morbidity and mortality of people, along with its economic cost through the development of appropriate indicators, assessments, and monitoring systems, and

·

Continue to expand the coverage of safe drinking water and sanitation to achieve the goals stated in the Millennium Development Goals and the Implementation Plan of the WSSD, by focusing national efforts in eliminating the gap between rural and urban populations.

Addressing the increasing vulnerability of the region’s population and ecosystems Global environmental changes, such as climate change, ozone depletion and the spread of hazardous chemicals, including persistent organic pollutants (POPs), and genetically- modified organisms (GMOs), pose an enormous threat to the human populations and natural ecosystems in Latin America and the Caribbean. National governments in the region will need to prepare themselves to face the consequences of: ·

increased frequency and severity of extreme climatic events (e.g. hurricanes, floods, and droughts) and associated negative impacts (e.g. human losses, economic disruption, forest fires and decreased food production);

·

Promote the use of renewable and clean energy sources in urban industrial activities and transport.

·

Promote the development of the public transport network, including non-combustion vehicles, in city and town planning;

·

Expand efforts to reduce the level of air pollution and contamination in medium-sized cities as well as from small and medium-sized enterprises within all cities, while continuing the traditional efforts in the region’s large urban centres;

emerging threats related to a warming climate (e.g. expansion of the area affected by vector-borne diseases, change in the composition of natural ecosystems, impacts of sea level rise, etc)

·

increased incidents of health effects caused by the depleted stratospheric ozone layer, especially in countries such as Argentina, Brazil, Chile, and Uruguay, and

·

potential harm caused by human-made substances such as chemicals used in agricultural and industrial practices, POPs and genetically-modified organisms and transgenic crops.

·

·

·

Reduce solid waste generation by implementing education and awareness-raising initiatives that promote reduction of waste by the general public and business owners, expanding recycling options available in urban areas, and promoting alternative and ecofriendly materials and packaging in the market. Under the guidance of central and local governments private companies could be invited and subsidised to establish recycling businesses; Reduce the amount of waste deposited in non-sanitary landfills by investing in more efficient use and improved maintenance of the existing sanitary landfills and in the conversion of non-sanitary landfills to sanitary ones;

Chapter 5: Options for Action

Suggestions for action: ·

Promote the full adoption and implementation of the Kyoto Protocol, establishing links to relevant multilateral agreements and plans of action related to social and trade issues and, where necessary, making such adoption an integral part of any regional trade agreement;

Environment Outlook

·

·

Strengthen regional capabilities and institutions needed to gather information and put in place mitigation and adaptation measures for both short-term variability and long-term climate change; Promote the conservation and restoration of ecosystems whose deterioration has increased vulnerability to certain types of disasters, so as to regain their capacity to provide environmental services (e.g. forests for landslide prevention and soil conservation, water catchment areas for the prevention of water shortages, wetlands for flood control, and mangroves and coral reefs for the protection of coastlines);

·

Strengthen the national capacities of vulnerability assessment, with appropriate use of vulnerability indices, to reduce the exposure of regional populations to disasters and risks resulting from extreme environmental events and changes;

·

Ensure better land-use planning and construction regulations in order to improve sound management of environmental goods and services, and enhance security for new and existing human settlements;

·

Undertake natural disaster preparation, prevention, control and mitigation measures focusing on education, organisation, the installation of early warning and information systems, systematic drills and on mobilising communities to be more aware and better equipped to deal with risk;

·

Continue national efforts to ratify and comply with the Montreal Protocol and its amendments (e.g. eliminating production and consumption of ozone-deplet-

247

ing substances, developing national legislations, implementing licensing systems etc.); ·

Work with developed nations to maintain international and multilateral support for initiatives (including the Ozone Action Programme) designed to promote technology transfer, knowledge exchange, and use of alternative substances in developing countries, and

·

Sign and ratify the Rotterdam Convention, which binds exporters trading hazardous substances to obtain a Prior Informed Consent (PIC) of importers before proceeding with the trade, and the Stockholm Convention, which is a global treaty to protect human health and the environment from adverse effects of POPs, as the first steps in dealing with the impacts of the harmful substances.

The challenges for the 21st century Integrating the three pillars of sustainability —by far the greatest unresolved global challenge for the 21st century— will require addressing their links in all fields, including legal, institutional, political, cultural, technological and ethical. Each of these dimensions represents opportunities for some and constraints for others, which policies must identify and account for (Banuri et al., 2002; Henderson, 1997). Environmental sustainability is still seen as a barrier to current production and consumption patterns in the region, rather than an asset. There is still little acceptance that any effort to change these patterns will foster

tive profitability of economic activities must be achieved by reallocating public subsidies and incentives towards desirable activities, thus providing greater short-term revenues for long-term, sustainable development. It is worth noting that the nations of the region are aware of many of these challenges, and of the paths leading to a sustainable future. Perhaps the most recent evidence of this is contained in the Latin American and Caribbean Initiative for Sustainable Development, approved by the regional Forum of Ministers of the Environment in August 2002 at the WSSD (UNEP/ROLAC, 2002; see Chapter 3). © R.

comparative advantages in global markets with longterm environmental and economic benefits.

·

Eradication of poverty and social inequalities;

As indicated in Chapter 2, Latin American and Caribbean countries exhibit some of the widest income gaps in the world. Both extremes of these gaps have serious negative consequences on the environment, and cause concern about the region’s social sustainability. From an institutional perspective, the reallocation of resources implies profound changes in the underlying structure of incentives and requires strong political backing from the population. One of the key challenges in this area is the need for sustainable territorial management, which requires intense social participation and innovative local and sub-national institutional arrangements (Altenburg et al., 1991; Sunkel, 1991).

·

Introduction of an environmental dimension in economic and social processes;

·

Strengthening of technical and vocational training institutions;

· ·

Promotion of human resources development, particularly in information and communication technology Development of micro-enterprises;

·

Empowerment of civil society organizations;

·

Promotion of economic diversification;

Such actions imply strong democratic authority at the national level and above all firm democratic global governance of international multilateral institutions (Capra, 2002). In Latin America and the Caribbean, Brazil, Mexico and Argentina in particular are playing a vocal part in this drive, but many smaller nations can also be expected to make a significant contribution.

·

Promotion of regional cooperation and collaboration that increases the region’s access to international markets;

·

Implementation of qualitative and analytical work on vulnerability indices to define the economic, social and environmental vulnerability of countries concerned;

·

Sustainable management of water resources;

·

Sustainable generation of energy and increasing the use of renewable sources;

·

Better management of protected areas for the sustainable use of biodiversity;

·

Adaptation to impacts caused by climate change and sustainable management of urban and rural areas, with special emphasis on health, environmental sanitation and on minimizing risks and vulnerability to natural disasters;

·

Actions to promote scientific and technological innovation, strengthening research and development institutions and increasing existing sources of financing;

Globalisation is the other leading area of concern, where visionary policies are needed in the region. Business-as-usual in the global market appears increasingly dependent on social exclusion and labour deregulation. This constraint must be countered with regional policies orientated towards improvements in quality of life, including water and sanitation, alternate energy sources, transportation, and a comprehensive drive for dematerialization. The region’s development will perhaps need to follow a different path from that taken by developed countries, emphasising less wasteful consumption, cleaner technologies and production patterns that do not emulate the richer countries. This will need specific policies from the region and the world community. One of the most important changes required is in current speculative financial markets. Change in rela·

The Initiative’s priority areas include the following, which together provide finer detail on how such a regional vision for the new century can be developed:

Development patterns in the region can be changed by governments, international organisations and civil society to better reflect environmental and social needs. Each has an important role to play. Pressure needs to be exerted at the same time by the region as a whole to reverse the external forces that render its countries so© R. Burgos cially, economically and environmentally vulnerable - especially the small insular states in the Caribbean. Action, such as the steps outlined above, needs to become part of mainstream decision-making before it is too late and the region reaches a point of no return.
