Food Security in Africa and Asia: Strategies for Small-scale Agricultural Develop-
Preface
Having lived in South East Asia, as well as on the African and South American continents working on agricultural projects for some forty years, the writer acquired an appreciation of the harshness of life for so many of the rural and urban peoples living in so-called World Development Regions (WDRs). The difficulty of living on a knife-edge under uncertain and varying circumstances of governance, health and education, infrastructure, soil fertility and climate can only be understood by people who have to spend their energy to survive and improve the circumstance under which they were born. The population pressure now being brought to bear on the globe’s resources only increases the uncertainty of life in such regions. Increasing world population makes the achievement of sustainable food security for the people living in WDRs acute. It is argued that small-scale agricultural development in development regions is important in this regard and that the input of the local small-scale and subsistence farming community, with the active participation of national and international agencies and governments, is necessary if sustainable small-scale agricultural development in WDRs is to be achieved. Policy makers of such agencies should involve themselves closely with smallscale farming communities in establishing ways and means to work towards achieving this aim. Due to modern communication and transportation methods, our world, although rapidly becoming smaller, at the same time is enlarging greatly, which brings a new and challenging world upon us. All nations, whether developing or developed demand their place in this changing new world. Due to their resources the developed world might profit more from the new opportunities opening up than the low income countries. There is a danger for the existing gap between these two streams of nations widening further. Financial aid for the developing world is important, but most important of all is technology and the opportunity for people in the developing world themselves, by means of access to viable markets, to make full use of resources available nationally and internationally. The most important thing for success is the attitude of the individual and therefore agencies, including governments worldwide, towards such opportunities. In that context it is pressing that the necessary assistance be given to small-scale and subsistence farming to promote small-scale and subsistence agricultural development, seen as essential to combat food insecurity.

Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
INTRODUCTION
The premise of the book Small farmers’ interests
Local, regional and national agencies’ interests
International institutions and donors’ interests
Rural and urban populations’ interests
Organizations and Institutions: Commission and deliver improved food security
The overall concept
This book builds on the premise that food security in low-income countries may be achieved through sustained effort by the local small-scale and subsistence farming communities, with the active support from local, national and international agencies. It states that any such effort will endure only if those small-scale farming communities and subsistence farmers feel that their interests are protected. Therefore, those local communities should be involved in the process of working towards sustainable food security to the extent that they consider that they ‘own’ the project designed for that purpose. To achieve this such a project should be based on the concept of participatory action and learning. However to protect the interests of financial donor organizations, it should be underpinned by a blueprint model which guarantees achievement of upward accountability from those implementing the project, to financial donor organizations. Therefore, the book is directed towards policy makers of local, national and international organizations and agencies which are prepared to listen, learn from and work with local farmers and their representatives. This is subject to it becoming clear to these policy makers during the process of project development and implementation that the aim of securing sustained commitment from local small-scale and subsistence farmers can be achieved. This will depend on these farmers believing that they would secure an acceptable livelihood from small-scale farming based on the development project. Subsistence farmers would be strengthened and have an incentive

Introduction to stay on the land, reducing the pressure on urbanization. The relationship between the various ‘actors’ involved in the process, is depicted in broad terms in Figure 1.1.
The contents summarized Chapter 1 defines the problem the establishment of food security in low income countries is faced with. It offers an approach towards coming to grips with the problem, the causal factors of which are seen as population pressure, poverty, land degradation and unstable environments. The approach clarifies the involvement of the various players with different and varying interests in the process of arriving at a solution to the complex problem of achieving sustained food security. Alongside the involvement of local, national agencies and governments and international institutions, the commitment of local small-scale farmers’ organizations and principally amongst them subsistence farmer groups, is regarded as crucial in setting standards and norms as benchmarks for action based interactive participation. As the resources of small-scale and subsistence farmers’ households are seen as central to the delivery of food security, they are examined in Chapter 2. The discussion is set against the background of population density and land use. To keep the analysis focused, it is limited to conditions found in the World Development Regions (WDRs) of Sub-Saharan Africa (AFR) and South Asia (SAS). Chapter 3 describes the work to be done to engage the local and small-scale and subsistence farming communities. A monitoring system aimed at assessing the level of their ongoing commitment is developed. A related model, incorporating fac2
tors at play in the ‘expert environment’, and the ‘socio-political environment’ working towards promoting a participatory learning process approach, indicates control action to maintain that commitment. Participatory learning and action (PLA) by all, including small-scale and subsistence farmers operating in the socio-political environment is essential to make the model work. To establish that the small-scale and subsistence farming communities accept that their involvement in interactive participation (see Glossary) to achieve sustained food security is at the core of the intervention, Chapter 4 puts forward a ‘findingout’ process. Based on this concept diagrams and models regarding the achievement of sustained agricultural production and a stable landscape are developed. In Chapter 5 ideas put forward in the models of Chapter 4 are discussed. This is done in the context of a research process as a basis for testing the concepts by means of questionnaires and interviews, directed to potential donors, ‘experts’, and small-scale and subsistence farmers. Subject to answers from the research process, the proposition entailed in the model worked out for a participatory approach in Chapter 3 is tested by means of a number of activities. The ‘expert environment’ is approached by donor organizations and/or international institutions, to find out who would be prepared to undertake a feasibility study under terms of reference relating to the concepts indicated above. The ‘socio-economic environment’ is tested more thoroughly than in the initial stage (Chapter 4) by ‘expert’ organizations also setting up a feasibility study about that aspect. They commission suitable staff to obtain the required information from the small-scale and subsistence farmers. A

Introduction model guiding farmer-led research under a combined participatory learning process and blueprint approach is set up leading to demonstration plots showing increased crop production. These plots are used to motivate increasing participation by small-scale and subsistence farmers by means of a monitoring system driven by farmers who have consented to take part. As sustainable crop production depends on a stable landscape, methods to promote this are included in the demonstration plots and monitoring system. Chapter 6 indicates broadly a number of challenges presented by natural and man-made factors which are beyond the control of those acting in the process discussed above. Population growth and density are examples of trends or changes in ecosystem processes as expressed for example by unreliable rainfall. Land use, due to its impact on the landscape is another aspect affecting the livelihood of small-scale and subsistence farmers. The consequence of local political instability is a further factor in this regard. The effects of these factors point to the need for agricultural production to be competitive. In that context the intensity of the use of agricultural land and cropping intensities in developing countries are looked at. The technique of intercropping is discussed in some detail. The potential advantages of this system with regard to the use of solar energy by leaf canopies and of the soil profile by root systems is highlighted. The possible use of irrigatioin is given due attention. Chapter 7 considers competition between organizations for land to be used for the production of plant crops.
An example of this is the production of crops for food, or alternatively for biofuel. This is looked at in the context of population densities and the suitability of land for surface irrigation against the overall background of chronic undernourishment. As the target set by the World Food Summit for the reduction of this undernourishment seems unlikely to be achieved, it is argued that insight is needed to ensure that crops for bio-fuel are grown on relatively marginal land and that deforestation is reduced to a sustainable level. The connection between the factors which affect food security is highlighted. Chapter 8 states that if an intervention directed towards promoting food security in a World Development Region (WDR) is to be successful, the region needs to be surveyed to determine in general terms its characteristics regarding its agro-ecological zones. This then could lead to an assessment of its potential distribution of appropriate farming systems (see Glossary). These are defined broadly as a population of small-scale and/or subsistence farms with similar resources, household livelihoods and constraints. Highland temperate mixed crops, or forest based crops with a moderate or extensive prevalence of poverty are examples. To facilitate cooperation by farmers’ groups, Chapter 9 considers farming systems. Based on the examination of resources referred to in Chapter 2, a number of different farming systems are selected for typical households. Based on that selection in a region or country in AFR and SAS, the research process referred to under Chapter 5

Introduction can be initiated and action started to work towards establishing the demonstration plots mentioned in that chapter. This is indicative of the difficulty of the tasks involved. The need for capable adaptive management is emphasized. The final Chapter 10 considers the background for potential tensions between the interests of agencies working under upward accountability and the interests of their staff working on the ground, facing conflicting demands for participation from local and donor interests. The need for positive communication between staff
4
from donor organizations and small-scale and subsistence farmers representatives is emphasized. Sustained political will from policy makers of international and national agencies and national governments is essential if relevant action by local small-scale and subsistence farmers’ organizations and groups, supported by donors’ organizations towards vitally important food security, is to be successful. Population pressure and climate change put unavoidable weight on this issue.

Defining the Food Security Problem
The problem tree
1.1 Introduction
Ineffective rural household income strategies. Social differentiation. Low efficacy of national and international institutions
Falling agricultural productivity Reduction in fallow durations
Unsustainable farm sizes Urbanization
Difficulty in maintaining effectiveness and efficiency
Finding a viable answer to the question of how to improve food security should not be seen as a ‘problem’, but rather as an endeavour to analyse an ever-changing situation. The term ‘problem’ is indicative of a ‘hard’ process which, via analysis of ‘facts’, arrives at a solution. Figure 1.1 presents a ‘hard’ model. It identifies the ‘focal problem’, the ‘causes’ of the problem and the ‘effects’ of the problem.
Effects of the problem
The Focal Problem: Population pressure Land degradation Vulnerable food security. Poverty
Causes of the problem

The complexity of the problem presented by achieving sustained food security needs to be defined. This justifies an approach based on soft systems methodology.
Economic externalities Market failure Urbanization
Although this figure is useful, in that it helps to focus onto the problem, it does not bring out the fact that we are concerned with an ever-changing situation. For this reason we should think of the subject under discussion as representing a ‘problem situation’. This term ‘problem situation’ is indicative of a ‘soft’ process, containing fluid and everchanging elements. A ‘problem situation’ is open to analysis by means of soft systems

and
This analysis starts by building a picture showing the main stakeholders and related issues. In that context Checkland and Scholes, 2000, pp. 45-48 point out that “it was found useful to think of the intervention structurally as entailing three roles”.
Analysis One. • The role ‘client’ - the person or persons (or institutions) who cause the intervention to take place. In this case this is seen as the small-scale farmers’ communities in the WDRs of AFR and SAS. These should be regarded as powerful players in the intervention.
• The role ‘would-be problem solver’ (could also be ‘client’) is whoever wants to do something about the situation. In our case these would be national and international agencies and non-government organizations (NGOs). To ‘make the case’ to them, the intervention needs to be defined “in terms of their perceptions, knowledge and readiness to make resources available” (Checkland and Scholes 2000, p. 47).
• The role of the ‘problem owner’. The ‘problem solver’ decides who the ‘problem owner’ should be. The decision of who fill these roles is called ‘Analysis One’ in SSM (Checkland and Scholes, 2000, p. A16).
Analysis Two. This attempts to present a framework for the social and political analyses. That is to say a framework of the roles, norms and values and an ongoing analysis of the ‘commodities which embody power’ (Checkland and Scholes, 2000, p. A19). This represents the view 6
that social reality should be seen as continuously constructed and reconstructed by individuals and groups. The difficulty will be to arrive at a usable framework to underpin an analysis of the interplay between small-scale farmers’ groups and organizations / institutions involved with the project.
Analysis Three. This describes the distribution of power in the social situation. As sensitive issues might come to the fore, this will be difficult.
1.2 The core concept Increasing population pressure potentially leads to land degradation, making achieving/maintaining food security more difficult. Delivering a stable landscape (see Glossary) under increasing population pressure may be central for agricultural production to lead to food security. Appropriate technologies applied to land and water management and crop production management drive agricultural production. Therefore small farmers’ organizations, as the ‘owners’ of these technologies, should be most closely involved in the design and implementation of any intervention dealing with food security. The reduction of poverty in rural areas might result from action related to the above. In urban areas a reduction of poverty could be based on a promotion of industrialization, commerce and transport. Lively interchange between the two areas could achieve desirable diversification. If all this is to be achieved, active and well planned and executed cooperation from international, national and local institutions with small farmers’ and citizen groups will be needed. International agencies, consultants and financiers

should be involved with a view of underpinning the work to be done by these small farmers and citizen groups and organizations. As the financial resources to carry out the work with a reasonable chance of positive progress will not be available in the areas concerned, financiers should be involved. National and international institutions should keep abreast of progress and intervene if necessary. The interchange between rural and urban populations is indicated as impor-
tant. These ideas are depicted in Figure 1.2.

Chapter 1 Defining the Food Security Problem nected, require different strategies (see Glossary) for their implementations. Fundamental at this point is that the matter is approached from the basis of the ‘world view’ (W) of this author that “interactive participation” (see Glossary) is necessary if sustainable and equitable rural development is to be achieved. This means that the so-called ‘customers’ (C), that is the people who do (P), decide what to do (Q), once they have reached the insight why it should be done (R) (Checkland and Scholes, 2000, p. A22). This SSM concept of ‘doing P by Q’ finds an answer to the question of ‘how?’. Importantly, to quote Checkland and Scholes (p. 23) it is necessary “to be sure that there is a plausible theory as to why ‘what to do’ is an appropriate driver to TABLE 1.1.
motivate people (here the ‘actors’) to act”. For this reason the ‘purposeful activity’ for which we wish to build a model and who must be clearly defined. This is done by formulating the so-called SSM ‘root definitions’. These definitions indicate the core purpose of the ‘purposeful’ activity. In SSM that ‘core purpose’ is expressed as a transformation process (T). Importantly it transforms the input, seen as a form of some entity, into output, here a new form of the same entity. For instance the technology used to produce a crop could be seen as an entity. SSM root definitions should be formulated by considering the elements shown in Table 1.1.

This promotes our thinking in layers which is useful when it comes to model building. The centre (layer) of the process is the association of ‘transformation’ (T) and the worldview (W) which gives the process meaning. This underpins the involvement and actions by the ‘customers’ (C) and ‘actors’ (A), representing the top layer. Underneath T and supporting 8
(or otherwise) the process, are the people or organizations who have the power to stop it all (the ‘owners’, O).
1.4 Concept pictures These pictures endeavour to set out the relationships between stakeholders, issues and actions,
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Concept pictures central to the subsequent modelling process. As we are considering the improvement or increase of agricultural production leading to food security, as well as the achievement of a stable landscape and a reduction of poverty, this section will be divided in appropriate sub-sections. The circumstance that the environment contains elements over which the system has no control, is part of this. 1.4.1 The increase of agricultural production In the context of the rising population pressure, an increase of agricultural production is essential. Figure 1.3 presents a concept picture comprising elements affecting this subject. It shows the relationships between stakeholders, and the issues to be considered by those stakeholders. We are engaged with finding ways and means by which agricultural production can be optimized by designing a model indicating commonly agreed actions and action sequences. We believe that the concept of ‘adaptive management’ (see Glossary) is at the core of the process. This means that when beginning to consider strategy (see Figure 1.2 on page 7), adaptive strategy is drafted so that hypotheses about the way in which the production of new plant material responds to human activity, can be tested. Whilst implementing the strategy, learning occurs. Should the strategy fail, it can be adapted, and improved policies applied. The following will use ‘concept pictures’ and Analyses One, Two and Three, discussed in Section 1.1 above, on which subsequent modelling will be based. A purposeful activity can, of course, be
expressed by different transformations, derived from different interpretation of the purpose of the activity. This real-life complex agro-ecosystem is affected by state factors (see Glossary) which, perhaps especially in AFR and SAS, are highly variable and over which the system has no control. For this reason, if the transformation is to achieve its long term aim of being successful, the local small-scale farmers have to be closely involved with the experiments. They would also judge whether any transformation (T) of changing input to output indeed is successful in the long term, by subjecting it to three test criteria (Forbes and Checkland, 1987):
• the first criterion, E1, efficacy, checks whether the means chosen to produce the output, actually work;
• the second criterion, E2, efficiency, checks whether the inputs are efficient; this is done in the sense of the ‘amount of output divided by the amount of resources used’, or inputs being positive;
• the third criterion, E3, effectiveness, checks whether the transformation meets its long term aim. By ensuring that the farmers (or farmers’ groups) have the power to carry out these checks, the intervention can be morally justified. In case this monitoring, based on agreed measures of performance, indicated failure, local farmers’ groups, together with local institutions would have the power to take control action. Learning would have taken place, revised experiments designed, leading to revised strategy and revised policies. At this point the cycle of monitoring and taking control action would start again. These principles will come to the fore in the model to be worked out in Chapter 3.

Political system. Politics “is a process by which differing interests reach accommodation” (Checkland and Scholes, 2000, p. 50). The accommodations reached, or for that matter, modified or dissolved, by politics, will depend on the disposition of power. Politics therefore can be seen as a “power-related activity, concerned with managing relations between different interests” (Checkland and Scholes, 2000, p. 50).
The final element E-environment merits special emphasis. It is under this complex factor where ‘customers’, ‘actors’ and ‘owners’ will work to ensure the success of the intervention. The natural resources, as determined by the factors climate, parent material, topography. potential biota and time are given and thus beyond the control of ‘actors’ involved in the intervention. How they deal with the social and
political systems will drive the impetus the intervention may generate. Based on the stakeholders and their description as given in Table 1.2. the following root definition for this learning process approach is set up. A conceptualized model, based on our understanding of the problem situation, as set out in this section, is worked out in Chapter 4.

Chapter 1 Defining the Food Security Problem BOX 1 Root definition for a learning process approach aiming to improve agricultural performance. A system to improve the agricultural performance of the rural agricultural sector through the mobilization/enhancement of local knowledge in a sustainable and equitable manner to contribute to economic development and improved food security for the nation, thereby raising the productivity capacity of society. 1.4.2 Achievement of sustainable landscape stability The security of any life form depends on the stability of the landscape. The viability of life for all organisms not capable of capturing the energy of light by themselves (chemotrophs), requires consuming organic molecules created by phototrophs (organisms capable of capturing the energy of light). They need these organic molecules for the energy laid down in their chemical bonds. Phototrophs capture the energy of light by means of photosynthetic pigments. Plants, algae, cyanobacteria and some bacteria, capable by themselves of photosynthesis, are phototrophs. Under ‘normal’ conditions plant life depends on natural resources, amongst which climate (temperature and water) and soil are the most important. The control over soil formation is, in part, represented by the state factors of parent material, climate, topography, and time, over which (arguably - the ‘changing climate’ debate) there is no control. Human activities are another, and for us the driving factor. See also Chapters 5 and 6. Against this background it can be seen that the management of vegetation, of which crop management technology is a part, the management of land use and that of water use are important factors in any 12
drive to achieve the stability of the landscape. There is a close involvement of a number of stakeholders as ‘customers’ and ‘actors’ (CATWOE elements). The effect of these management practices on the balance of atmospheric carbon dioxide is an important spin-off. Quite apart from that, however, we emphasize that the long-term viability of any standard of living depends on the stability of the landscape.
Concept picture.
Relationships between stakeholders, and the issues to be considered by the stakeholders are shown, again in a broad-brush manner, in Figure 1.4. Based on this, action the stakeholders consider appropriate will be based. To define that action, in the form of a conceptual model, a ‘root definition’, based on CATWOE elements, needs to be composed. The rural population is heavily involved as ‘customers’ (here beneficiaries). At the same time, because of their involvement in doing the project, they also are ‘actors’. Due to cooperative research they (the ‘actors’) arrive at (the ‘transformation) an understanding that for their particular region there is an optimum balance between the areas which should be under arable, pasture and savannah land, respectively. Because their livelihood depends on the landscape, priorities regarding that balance would be established.

Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
The learning process approach 1.5 The learning process approach If food security and landscape stability are to be achieved as far as possible, participatory learning and action (PLA) is central to the process. Boxes 1 and 2 indicate the importance of mobilization and enhancement of local knowledge. Our world view indicates that we think that participatory action and learning, that is between so-called experts, local institutions and farmer groups, is necessary. The root definition given in Box 3 turns on the term ‘insight’ in the sense of ‘the ability to discern the true or underlying nature of something’ (The New Penguin English Dictionary, 2000). The difference between the root definitions in Boxes 2 and 3 is that the intervention detailed in Box 2 aims at defining what to do by various people and institutions to achieve landscape stability through some practical activity (activities). In contrast the definition given in Box 3 aims at defining what to do by various groups of people and institutions to enhance their own insight into the importance of the relationship between landscape stability and food security. The importance of the latter lies in the need to ensure that the actions referred to
in Boxes 1 and 2 are actions sustained in the long term. It has to do with maintaining the effectiveness of the intervention stated in Box 2. It has to do with finding out about the culture in which the work is done, which is crucial to the long term success of the processes of Boxes 1 and 2. The concept of ongoing discussions about the importance of landscape stability is depicted in Figure 1.5. The CATWOE factors used to arrive at the root definition stated in Box 3 are given in Table 1.4 (see page 17). Note that the transformation aims at improving insight needed to support the common purpose of the intervention. Groups and organizations of small-scale and subsistence farmers, as part of the local rural population must be heavily involved in the discussions, they being the people who via their use of the available arable, pasture, savannah and woodlands, create impact on the stability of the landscape. The procedure should arrive at an open channel of communication between the actors indicated in Table 1.4. The input of agricultural extension services, civil engineers and agricultural economists could be regarded as especially important at this stage. Their insight of the importance of the impact of infrastructure on landscape stability should be central to their work.

For this reason the ‘environment’ as far as the social and political systems are concerned is especially important. ‘Owners’ may be firmly embedded in social and political systems. When this culture threatens to bring the process to a halt, it is vitally important that international institutions bring pressure to bear with a view of bringing the process back into line. It is realized that this may be very difficult, if not “almost” impossible, but according to
our world view, the well-being of everyone depends on it. Prior to dealing with the problem described here, it is necessary to have a closer look at small-scale farmer households. This is necessary because of their important involvement in dealing with the problem of achieving sustainable food security in the context of maintaining a stable landscape.

CHAPTER 2
Evaluating the Resources of Small-scale and Subsistence Farmers 2.1 Introduction Against the circumstances of steadily rising populations and pressures on the supply of food, effective farming in the context of small-scale farming in AFR and SAS is essential. This chapter presents background against which later chapters should be seen. This is because small-scale farming families in AFR and SAS are major players in the learning process. The impact of the environment on the resources of these families to produce sufficient food to meet the needs of their households affects their interest as to whether or not to take part in that process. This is relevant as it is claimed that the achievement of sustained food security depends on this level of interest (see Figure 1.3 on page 10).
FIGURE 2.1. A woman farmer in Fiji Photo HB
To sustain the present level of agricultural production by the household, the small-scale or subsistence farmer may be involved in ‘slash-and-burn farming’, thus converting forest to crop land Although in its early stage this might be a win-lose situation (farmers’ income and food production ‘gain’, but forest conservation ‘loss’), in the long term it turns into a lose-lose situation, due to land degradation and declining productivity. A win-win situation, that is in some sustainable manner improving agricultural production on the small-scale subsistence farm, without adversely affecting forest conservation is what should be the aspiration. Apart from crop, pasture and forest land, there may be areas of fallow, savannah and brush land. Therefore, increases in crop-land and pasture do not necessarily have to come from the area under forest.
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development 19
Chapter 2 The Resources of Small-scale and Subsistence Farmers The FAO estimated that during the first half of the 1990s each year 12.7 million ha of tropical forests was lost. Legal and/ or illegal logging may have a more devastating effect on the land area under forest than the slash and burn agricultural method used by small farmers who operate in a forest-frontier area. Ongoing deforestation leads to a reduction in total leaf area of plants, with a potentially disastrous effect on global rainfall, due to reduced evapotranspiration.
are endowed with sufficient resources to enable them to accumulate income, thereby expanding means of income, such as land. To farm that additional land may go beyond the capacity of family labour. The household therefore may (also) employ labourers from outside the family household. Such farmers may evolve further and become capitalist farmers, increasing their wealth on some continuous basis. This refers to petty commodity production, defined as
Against this background it is acknowledged that small-scale or subsistence farmers, operating in World Development Regions, strive to improve their livelihoods as and when the opportunity arises. This opportunity may be to convert forest to farm land. On the micro-level the question of how a win-win situation, that is small farmers’ income sustained and improved, forest conservation not adversely affected, might be achieved, is at the core of this writing.
A distinctive form of production in capitalism that combines the class position of capital and labour within small, typically ‘household’ or ‘family’ enterprises. (Bernstein et al., 1992, p. 32).
2.2 Small-scale and subsistence farmers’ households The concept of small-scale and subsistence farmers is defined below. This is important in the context of increased involvement of small-scale and subsistence farmers in rural development. The traditional distinction between ‘rich’, ‘middle’ and ‘poor’ small-scale and subsistence farmers is described as follows.
Rich small-scale farmers’ households The term ‘rich small-scale farmers’ refers to those small-scale farmers who 20
The goods produced in addition to subsistence production (use values), are traded for other goods or cash (exchange values). The household uses its endowment for trading [trade entitlement, (Wilson, 1997, p. 27)]. The subsistence minimum is ensured before the smallholder faces the risk of trading. The purchased or imported goods obtained from trade, can be seen as a net gain resulting from the effort of using extra labour to produce the crop exported by the household (Myint, 1958).
Middle-income small-scale farmers’ households The term ‘middle-income small-scale farmers’ refers to those small farmer households capable of meeting the demand of simple reproduction. This is defined as Reproduction of producers and their means of production on the same scale of productive assets and incomes (Bernstein et al., 1992, p. 31). Such small-scale farmers can maintain their means of production. This enables
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Small-scale and subsistence farmers’ households them to raise the next generation of family labour to work their endowments. This is a direct entitlement, referring to own production and consumption of food (Wilson, 1997, p. 27).
Poor subsistence farmers’ households The term ‘poor subsistence farmers’ refers to those who are subject to a simple reproduction squeeze on their endowPetty commodity production
Family enterprise farm
ments. They have little, if any choice in finding a source of income. They may be squeezed to such extent that they have to go and live in towns and cities in the hope of finding some source of income. They may work for ‘rich’ small-scale farmer households. In such cases they use an exchange entitlement (Wilson, 1997, p. 27) by working for someone else, for which they are paid (Bernstein et al., 1992, p. 33).

Chapter 2 The Resources of Small-scale and Subsistence Farmers ence farmer family households do not occur in the ‘pure’ form stated above. For instance, families involved in petty commodity production may well have members who at certain times use their trade entitlement, and at other times an exchange entitlement, to enhance their income. Intensification of petty commodity production, such as made possible by the ‘green revolution’, increased opportunities for the ‘rich’ small-scale farmer households. However, at the same time, it increased the risks for the ‘poor’ subsistence farmer households, as the introduction of commodities such as fertilizers and seeds had to be purchased on a yearly basis. This stimulated some members of these ‘rich’ and ‘middle’ income families to use their exchange entitlement (working for pay) to support their families. Class divisions within the family often determine who does what. ‘Poor’ subsistence farmers do not have this kind of flexibility. The matter is further complicated by gender division of labour, that is to say who does what in terms of ‘male’ and ‘female’ tasks (Bernstein et al.,1992, p. 33). This varies widely between classes and groups in different rural societies. As shown in Figure 2.2, members of the same family can have different functions. It is apparent that the concept of ‘rural people’ and the manner in which such people may be affected by poverty, is highly complex. Those who are better off have more flexibility. Some family members may become urban dwellers and hold positions in political and/or commercial fields. The rural small-scale farming population, depending on circumstance, is faced with a variety of problems, involving them in a constant fight to protect their 22
livelihoods. This struggle for survival, frequently under conditions of poor soils and unreliable rainfall, as occurs for example in areas of AFR, requires considerable skill and flexibility, based on a profound understanding of local conditions. This understanding is central to the struggle for survival. The virtually unlimited range of combinations of various types of households, shown in Figure 2.2, is a consequence of this situation. It is apparent that if agricultural extension work directed at small-scale farmers is to be successful, which means that it leads to an improvement of people’s livelihoods, local circumstances must be taken into account. Participation by local people in any such effort is essential.
2.3 Population pressures Population pressures play a significant role in the sustainability of rural livelihoods.
A rural aspect The relationship between the use of land for agricultural production, forestry, pasture and fallow is important in the context of the available natural resource base. Closely related to this are patterns of farm activities and livelihoods, leading to many different farming systems (see Glossary) (Hall et al., 2001, pp. 8-13). Population pressure and poverty are factors of major importance with regard to the sustainability of the natural resource base. As the extent to which natural and human resources are available to small farmers in world development regions (WDRs) affects the potential to increase the production of agricultural crops, national income per capita and population

This section and that for the rural population however declined in percentage terms against that for the total population (Table 2.1).
Seen against the base year of 1991, the population section increased by 51% in TABLE 2.1.

This overall picture is highlighted further in Figure 2.3 below. Population density is important in the context of the availability of land for agricultural expansion.
The data of Table 2.1 and Figure 2.3 show that the agricultural population in the AFR region on the whole has kept pace with the rural population. Although this is not the case in the SAS region, the agricultural population here also appears

quite stable. As agricultural development, when based on small farms, relies on input by local people, maintaining this stability is significant. If the small-scale and subsistence farmers consider that their interest is protected in programmes devoted to small-scale agricultural development, this stability is likely to be promoted. 24
The table emphasized the importance of the availability of land for small-scale agricultural development, perhaps important especially in the context of subsistence farmer labour redundancy and rural welfare and its impact on political stability. It would, however, be quite erroneous to think that a future economy based solely
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Population pressures (or mainly) on agriculture could provide adequate income for everyone living in the countryside now and for those who will be born in rural areas in the future, not to speak of the masses of urban poor. Further to this, sufficient employment to ensure that the needs of those displaced or marginalized as farmers or agricultural wage workers, is not necessarily generated by industrialization and urbanization (Bernstein et al., 1992, p. 7). To give the TABLE 2.2. WDR
stability referred to above a chance, it will be necessary to consider what types of interaction, of agricultural and industrial linkages are required by any form this small-scale type of agriculture will take. Agricultural development might produce increased income for farmers and farm workers, which in turn can create demand for services and local goods.

Such development could be a driver for a reduction of rural poverty, mainly due to its effect on demand for services and local goods. This could create employment in the off-farm sector of rural areas and market towns, thereby stimulating urban development. One effect could be the lowering of urban food costs, but perhaps most importantly it could lower the rates of urban settlement and reduce urban poverty.
Table 2.2 shows that the World Development Regions of AFR and SAS are dominated to a significant extent by low national income countries, at 89.27% and 98.16% of their populations respectively. People in many of these countries live on less than $1 per day. These financial figures represent PPP dollars. Such averages can be misleading. Other yardsticks, such as the HDI (see Glossary) may be more appropriate. In this context it is disturbing that the HIV/AIDS pandemic as well as

Chapter 2 The Resources of Small-scale and Subsistence Farmers the ongoing migration of people who used to be involved in agricultural activities of some kind, to urban areas, leads to uncertainty over population trends. There appears to be an urgent need for viable agricultural development in these areas.
An urban aspect Development in the sense of economic growth depends arguably more on the well-being of the urban population than on that of the rural population. As illustrated in Figure 2.2, the situation is dynamic; urban and rural populations are inter-linked. Once rural people involved in elementary household production are enabled to get a step up the ladder towards petty commodity production, they have a chance to get involved in progressive reproduction and market their excess production in exchange for money. This then would be used to further improve the household, health and education. By then many in the younger generation would begin to look for jobs in urban areas and, perhaps most importantly, become involved in the ‘world of ideas’, designing new products and production methods. For this kind of positive flow hither and thither between rural and urban populations to be created and sustained, agricultural development is vital. This concerns not only the production of food and the maintenance of a stable landscape, but perhaps most importantly, it would be a source of energy, in the form of healthy and energetic people, on which industrial development depends. It would therefore appear that the best route to achieve sustainable growth in development regions and move towards a situation in which this becomes a possibility, is to promote agricultural development, centred on the small family farm, especially on the low
26
income households, involved in elementary household production. The so-called ‘family enterprise farm’ (Figure 2.2, see page 21) can be a good end-stage of development out of petty commodity production. This form of capitalist farming may evolve into the production of ‘industrial’ crops (that is more large-scale and managed for the specific purpose of meeting a budget set up for the achievement of a financial profit), thereby providing raw materials for processing and manufacturing. Exports of such crops may produce a net foreign exchange. This might be used (partly) for the purchase of imports to promote industrialization. In this context, industrialization, as far as it depends on active and productive workers, depends on food markets selling foods to such workers at affordable prices. To avoid a potential conflict with small farmers’ interests, governments may find it appropriate to subsidize the cost of food, at local markets, at the same time ensuring reasonable prices at the farm door. This is all the more important when urban workers live under a low-wage regime. The latter may be a fact of life until a stage of ‘take-off’ of industrial and agricultural commodity production has been achieved. To an extent such cheap food may be supplied by small-scale farmers, who, through their family supplied enterprise farm have sufficient resources to produce food for the market at prices capitalist farmers would be in a position of not having to accept [petty commodity production (see Figure 2.2 on page 21)]. Such supply of cheap food depends on the under-valuing of the labour that grows it and is prepared to sell it at low prices (Bernstein et al., 1992, pp. 41, 42).
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Population pressures As far as these small-scale and subsistence farmers are concerned, this would be a form of self-exploitation, which effective rural development (in the sense of achieving improving livelihoods) would get rid of. This would, however, drive up food prices in urban areas, forcing up wages of industrial workers. This would be an incentive for industrial production in such development regions to become more effective. Fewer people would be able to find employment at such higher wages. Improved circumstances in the rural areas and more competition for jobs in urban areas might help to put a brake on the tendency for increasing urban populations. It has been argued that if a sustainable and reasonably healthy society is to be achieved, close links between rural and urban societies need to be maintained. TABLE 2.3. a
Population levels for AFR and SAS The distribution of agricultural people as part of the total rural population is of interest in the context of the above. The rural and agricultural populations have increased quite rapidly during the period from 1991 to 2003 (see Table 2.1 on page 23) The bar charts show that from 1995 onwards the agricultural population, as part of the rural population, has remained quite stable (see Figure 2.3 on page 24). With respect to AFR, the increase in numbers from 1995 to 2003 shows 27%, 16% and 17% for total, rural and agricultural populations respectively. In the SAS region these numbers were 17%, 14% and 8% for total, rural and agricultural, respectively. An estimate of the yearly increases derived from these figures is shown in Table 2.3 below.

sectors for AFR appear fairly constant, but those for SAS show a fall in the increase of the agricultural population as part of the rural population for the period analysed. On the other hand, the rural and agricultural populations fell by 6% and 4% respectively in AFR for the period 19912003 and by 3% and 6% in SAS (Table 2.1, page 23).
proportion of the total population. The numbers are indicative of small-scale farmer redundancy and a transition process threatening rural welfare and political stability. This highlights the need for a more attractive rural livelihood, development of which might be promoted by the project indicated in Chapter 1.

Chapter 2 The Resources of Small-scale and Subsistence Farmers 2.4.1 AFR
2.4 Land use in AFR and SAS The availability of suitable agricultural land for productive use by increasing rural populations is a factor of major importance for the sustainability of a stable rural population. Data regarding land use put the above discussion in sharper context. Relevant data are presented in Table 2.4, illustrated in Figure 2.4 (see page 29).
TABLE 2.4.
The agricultural area in this region increased from 807 million ha in 1991 to 1,283 million ha by the year 2002. This represents 38% in 1991 and 60% in 2002 of the total land area. The arable and permanent area remained virtually constant at some 7% of the total land area. The increase in agricultural area is reflected in an increase in pasture and permanent area (Table 2.4). The potential productivity of this land is limited due to non-favourable climatic conditions, otherwise the arable and permanent would have increased.

However, if the people involved in family enterprise farming (Figure 2.2; see page 21) empower themselves to invest more in resources, it may become possible to convert some of this pasture land into permanent arable land, increasing petty commodity production. This might stimu-

2.4.2 SAS In the SAS region the situation could be seen as more complex in that the agricultural area, at 55% of the land area, remained constant for the period considered. The arable and permanent section also remained constant, at 44%, with no movement into the relatively small pasture and permanent area.
Here it appears that households involved in a family enterprise farm do not have much chance of increasing productivity by looking for more land. To achieve this increase in productivity, the emphasis would have to be on increasing yields. Education, effective agencies, such as those involved in agricultural and plant genetic research and extension work, appear most important.
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development

Chapter 2 The Resources of Small-scale and Subsistence Farmers In the context of the latter, a recognition of the ‘Farmers First’ or ‘People First’ concept (Chambers et al.,1998; Burkey, 1993) under the conditions prevailing in SAS may be even more important in SAS than in AFR. In both these regions (as in others) self-reliant participatory development, dependent on the people themselves and assisted by those ‘specialists’ who are willing to work and live for a time amongst them and who understand the concept of ‘reversal learning’, might have a chance of successful development.
2.5 Population density In densely populated low-income areas, the competition for arable agricultural land is strong. The aspects discussed in the previous sections come to the fore when considering population density. The contrast between AFR and SAS is striking (Table TABLE 2.5.
2.5). In AFR, as in MNA, ECA and LAC, competition for arable agricultural land may be less severe than in SAS and EAP, the latter two regions having a relatively high population density. The pressure on effective farming systems may be more pronounced in the latter regions. Once a reasonable food supply on the market has been achieved in these densely populated areas, there may be a higher incentive for those involved in a family enterprise farm, to go out and work for pay in urban areas. This may be especially so for these family members if they can become involved in industry. It is, at least in part, due to the influx of healthy young people coming from such successful enterprise farms, and which are open to ‘new’ technologies and ideas, that such densely populated areas have a chance of moving up the ladder of development.

Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Population density This also is the case for less densely populated areas, but here, if arable land is still available, there may be a higher incentive for more production of food for the market. In such regions, small-scale farmers may become involved in ‘expanded’ reproduction, increasing the land area under cultivation. They might begin to use other means of production, now beyond the capacity of family labour, by employing the labour of others. In this way, the better-off petty commodity producers may become capitalist farmers.
A down-side of this (perhaps optimistic) picture is that this can lead to social differentiation and clashes with other village members and holders of power. The economic aspects considered in this chapter are closely related to the resources small-scale farmers’ households have available to produce their crops, whether for direct consumption or for market produce. These resources will be considered in Chapters 8 and 9 in the context of farming systems, defined in Chapter 8.

CHAPTER 3
Alternative Approaches Examined
3.1 Relevant to participatory learning and action (PLA) 3.1.1 The acceptance of PLA PLA requires dynamic managing of change, involving all stakeholders in the monitoring, evaluation and corrective action. If these aspects are ignored, a lack of participation by ‘user stakeholders’ (Eade, 2000, pp. 125, 126), may lead to failure of the intervention.
FIGURE 3.1. Small-scale coffee farm in St Kitts.

It is quite disturbing that this approach, based on common learning through common action, does not appear to have been more generally accepted in former years, in attempts aimed at rural development. Rondinelli, when considering a project commissioned by USAID (1989), found that in a sample of 212 projects, just some 11% had a strong probability of being sustained once aid was terminated. Twenty six percent had poor prospects of providing long term benefits (Rondinelli, 1993, p. 2). An interesting and encouraging example of the benefit of capacity building and participatory management is provided by the irrigation system of Gal Oya in Sri Lanka, which did provide long-term benefits (Uphoff, 1996). This example shows that if those who provide assistance are prepared to learn and work with participants from the bottom up towards a common agreed aim, success can be achieved.
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development 33
Chapter 3 Alternative Approaches Examined Quite apart from the wastage of resources, which occurs when ‘user stakeholders’ are not involved with the monitoring, evaluation and corrective action of agricultural projects, is that ‘positive externalities’ defined by Uphoff as “benefits greater than costs that extend beyond the project, community or enterprise at TABLE 3.1.
hand”, are not accomplished to some satisfactory degree. When user stakeholders are fully involved with a development project they would have good reason to expect to profit from such long-term benefits which are external to the project. This would have a positive effect on their motivation to stay involved.

This is the average of the indices for the health of the population, measured by life expectancy, its educational attainment and its material standard of living, measured by gross domestic product per capita in PPP dollars (Allen and Thomas, 2000, p. 16). The potential focal problem is a difficulty of creating and maintaining an effective and efficient partnership.
Examples of such externalities from sustained rural development are improved access to markets, increased requirement and demand for schooling and health services and strengthening civil society (see Glossary). Positive externalities “represent the essence of sustainable development” (Uphoff, 1995, pp. 25, 26). A shortfall in downward accountability is contrary to the need ‘user stakeholders’ have to fulfil their capabilities and potential. It demotivates. Opportunity to learn
34
from a project does not materialize (Korten, 1984, pp. 182-185).
Stakeholder groups All this is all well and good, but as the need for an effective and efficient partnership between the various stakeholder groups is central to the PLA approach, we look at its potential benefits and problems, as well as at stakeholders, more closely in Tables 3.1 and 3.2. The complexity of a partnership arrangement depends on the interest in its success

Relevant to participatory learning and action (PLA) of the stakeholder-groups taking part. Amongst these and perhaps above all on the ‘world view’ of ‘outsider-stakeholders’, many of which do adopt a participatory approach. Once local people, such as a small-scale coffee farmer (Figure 3.1) have expressed their problems in the con-
text of the intervention, these local people may consider it to be in their interest to request strengthening of the input by ‘outsiders’. The need for those ‘outsiders’ to be prepared to learn and work with the participants from ‘the bottom up’, referred to above, comes to the fore here.

The highest priorities go to the staff of participating NGOs, the people who provide funds and have control over them and to the local farmers, as ‘users’ of the project. The Ministry of Agriculture has a
significant impact, especially as far as achieving the target or aim of the intervention is concerned. This, however, shows that effective cooperation, defined as “to act or work with another person, or other

Awareness of this common purpose, as far as financiers and regulators are concerned is based on their world view that ‘bottom-up’ control and participatory management is essential for success. As far as users are concerned, this awareness is based on a conviction that achievement of the targets (here improved agricultural performance based on a stable landscape) is vital for sustained benefit to all. Understanding that in fact there is a common purpose between the groups of stakeholders can be strengthened by applying the Feyerherm framework (see Table 3.3). These ‘What questions’ are important and should be considered by participants
36
during initial negotiations and ongoing implementation of the project. Once roles and contributions of each of the participants have been agreed to common satisfaction, this agreement should be recorded to form the ‘contract’ on which the partnership is based. 3.1.2 Setting standards for participation The success of PLA depends on sustained trust between the parties involved. Much of what has been stated in the previous section is based on the concept of ‘self-actualizaton’, defined as ‘the need a person has to fulfil his or her capabilities and potential’ (from OUBS course B600, Book 3, page 24). However a counter-balance to this ideal situation of ‘pure’ participation can be found in Cooke and Kothari (2001), as well as in Dichter (1989). These authors argue that aspects of ‘pure participation’ where
• people are involved in the design and implementation of a project, thereby influencing its development at every stage - by being decisive about key issues;
• people organize themselves to take action to deal with a shared problem, rather than reacting to the initiative of outside agencies (Eade and Williams, 1995, p. 15) may cause conflict, due to different levels of interests amongst the people concerned. Potentially this could result in the failure of the intervention. This point of view is exemplified by Dichter’s statement that “whether the management approach is ‘people-centred’ or ‘blueprint’ becomes less important than

To arrive at a basis suitable for our intervention, which aims at combining an improvement of agricultural production with the protection of a stable landscape, the four-stage model advocated by Rondinelli (1993, pp. 118153) is of interest. The four stages move from implementation of action to completion of the intervention as follows: TABLE 3.4.

Various approaches are compared in Figure 3.2 on page 37. The figure indicates that NGOs may involve subsistence farmers in research and use the results of that research, again in conjunction with the farmers, to look at the policy environment and decide (together) the approach to the design of the project. Alternatively, NGOs may identify and implement a project directly, that is without input from farm-
38
ers’ groups, by using a prescriptive or blueprint approach. 3.1.3 Root definitions and conceptual models regarding a blueprint and learning process approach As indicated in Figure 3.2, the design of a project based on successful subsistence farmer-led participatory research, which

It is here where the steps to be taken prior to implementation, that is from its identification to its preparation to its appraisal and finally its implementation,
should be based on the design approach as determined by the result of the participatory subsistence farmer-led research (see Figure 3.2 on page 37). This is where the

Chapter 3 Alternative Approaches Examined considerations stated in Tables 3.1 (see page 34) and 3.2 (see page 35) are of some importance. Local people may request strengthening of input by ‘outsiders’. To highlight the importance (and potential difficulty) of the arrow connecting the policy and project environment in Figure 3.2 it is useful to compare and contrast the blueprint and learning process approach and their ‘ideal type’ conceptual models. In the context of root definitions discussed below, see also Table 3.4.
Root definition for a blueprint approach. This concerns a system to “improve agricultural performance and land use of the agricultural rural sector by using expert agricultural and ecological knowledge and economic resources in a sustainable and equitable manner to contribute to economic growth”.
Root definition for a learning process approach. This concerns a system to “improve the agricultural performance and land use of the agricultural rural sector through the mobilization/enhancement of local knowledge/insight in a sustainable and equitable manner to contribute to sustainable agricultural production and sustainable economic development”. To facilitate our discussions, ‘ideal forms’ of the blueprint and learning process approach are shown in Figure 3.3 above. The main characteristics of these ‘ideal types’, relevant in the context of our discussion, are summarized as follows:
Blueprint approach.
Activities indicating how change is to be achieved are prescribed and take place under the control of ‘experts’. This is indicative of a mechanistic (closed) approach and a hier-
40
archical (command) structure. The success of the project rests on effective and efficient management. The process of managing the project takes place in an ‘expert environment’, basically excluding so-called non-expert user stakeholders.
Learning process approach.
This ‘ideal type’ takes account of factors outside the control of any one single agency. ‘User-stakeholders’, as subsistence farmers are involved in relevant dialogue and negotiations. They take part in the design and implementation of the project, thereby acquiring a sense of ownership of the project, promoting its sustainability. The process of managing the project takes place in a socio-political environment.
3.2 Relevant to ideal type models and ‘real world’ problem situations 3.2.1 The conflict As stated in Section 3.1.1 (see page 33), projects to manage improvement of agricultural performance whilst achieving/ maintaining a stable landscape rest on a dynamic management of change. This requires effective monitoring, evaluation and corrective action based on that evaluation, by user-stakeholders. A blueprint approach, which is mechanistic and based on hierarchy (command structure), is not suitable for that kind of problem situation environment. Typical for the problem situation is that it is affected by factors, such as climate, soil, slope which are outside the control of any single agency. To establish what is feasible, small-scale and subsistence farmers, with their knowledge of and insight into the local situation, will have to be involved in relevant dialogue and

structure, availability of markets, education, health) in the real world pertaining to the region where the project is to be implemented, will be instrumental to the extent that this is feasible. Circumstance may prevent effective participation.

Chapter 3 Alternative Approaches Examined Also, assuming that an agricultural development project, encompassing a drive to improve agricultural performance and achieving a sustainable stable landscape, will depend on investment by funders, such effective participation may, as yet, be beyond reach. As indicated in Figure 3.2 (see page 37) the donor community, such as NGOs involved in bringing the project into being, will be accountable to these funders. NGOs dedicated to this difficult work, will be supportive of the principles underlying participatory research and adaptive management, and try to find and work with funders supportive of these principles. However, also for these funder-organizations, even if of the not-for-profit type, results based on ROI (return on invest-
42
ment) remain a powerful driver for the control of agricultural (and other) development projects. 3.2.2 The combined approach It has been argued that the two approaches of blueprint and learning process, if applied as discrete ‘ideal type’ concepts, do not achieve sustainability of agricultural projects. ‘Effective participation’ will be essential for this. However, combining the two approaches can open an opportunity for learning by all, resulting in effective participation over time. The conceptual model for such a participatory approach, shown in Figure 3.4, illustrates this proposition.

Involvement of small-scale and subsistence farmers in a project towards achieving food security is essential. A process to assess the readiness of small-scale and subsistence farmers’ communities in AFR and SAS to take part in a project aimed at promoting food security is discussed in this chapter. Following Checkland and Scholes, one might use the conventional general descr]iption of SSM as a seven-stage process (see Figure 4.1). In our context this is helpful in that a clear distinction is made between the ‘real world’ and the world of systems thinking. In Chapter 1 we arrived at an expression of our problem related to ‘landscape stability’ and ‘increased production of food’. Root definitions (RD) of these problems were presented in Box 1 (see page 12) and in Box 2 (see page 14). From our discussion, and following Checkland and Scholes, it is clear that this conceptual model (see Figure 4.1) “gives too much an impression that SSM is a seven-stage process to be followed in sequence” (their page 27). The reason is that ‘awareness’ (Box 2) and ‘insight’ (Box 3, see page 15) relate to culture in

Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
The process SSM (see Abbreviations, Acronyms and Organizations) is used to guide this process. This methodology involves the people concerned in a learning cycle. It reflects “upon and debates perceptions of the real world, taking action in the real world. It reflects on what happens using systems concepts” (Checkland and Scholes, 2000, p. 28). The situation(s) in the real world, here food security and landscape stability, which are very much part of human affairs, are products of history, which can be looked at from different points of view. However, when thinking about these problems, it appears that classical management has been dealing only with the logic of the situation. SSM enables us to go beyond that important logic to “enable action to be taken in the full idiosyncratic context of the situation” (Checkland and Scholes, 2000, p. 28). This is followed through by referring to Figure 4.2 (see page 44).
4.2 The process 4.2.1 General When in accordance with Figure 4.2 we consider the ‘history’ of the problem situation, or why it has arisen, Figure 1.1 (see page 5) is useful. At the core of the problem are the ever increasing population pressure, economic externalities (see Glossary) and deforestation. This has to do with human behaviour or culture, or the social and political aspects of that behaviour. These can be defined from an analysis of the intervention (the ‘Finding out’ process discussed below). In accordance with Figure 4.2, above, it is essential to go through these analyses if a logic-based analysis of tasks (purposeful action) and issues (things about which there is disagreement between ‘would-be
improvers’ of the problem situation), is to be carried out successfully. The logic based stream of analyses aims at defining differences between conceptual models of participatory learning and action, landscape stability and food security, and the ‘real world’. The result of a stream of cultural analysis, that is to say of social and political aspects, considers these differences and determines which changes in the ‘real-world’ situation are desirable and feasible. Based on that interpretation action to improve that ‘real-world’ problem situation is recommended. Whether this action, that is the ‘Transformation’ of changing ‘Input’ to ‘Output’, is successful, would be judged by the ‘Customers’, in our case local small-scale and subsistence farmers and local agencies. This judgement would be based on the 3Es (see page 9). These ‘E’ criteria are all important. In our case however, the third, referring to ‘Effectiveness’ and answering the question whether the ‘Transfomation’ is meeting its long-term aim, that is improving livelihoods (not necessarily linked to economic growth) may be the most important. 4.2.2 The methodology followed In order not to lose track of these points, following Checkland and Scholes, 2000, the following sequence of events (stages) will be used.
Stage 1 - Finding out about the problem situation. An introduction to the problem situation (see Chapter 1) will be broadened in the present chapter.
Stage 2 - Developing a general model. This model is to be applicable to the three ‘E’ criteria. This model is to be set up in the current chapter.
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
45
Chapter 4 The Need for a Participatory Approach Stage 3 - Revised RDs and their conceptual models. ‘Root definitions’ (RDs) of three problem situations, considered relevant, have been presented in Chapter 1 (see Boxes 1, 2 and 3, on pages 12, 14 and 15, respectively). Based on additional information, discussed in the current chapter, these will be revised. Following the general model of stage 3, three conceptual models based on the three revised RDs, will be worked out.
Stage 4 - Comparing models and perceived ‘real-world’. The problem situation will be considered in terms of a blueprint and learning process approach. These approaches will be compared with the perceived ‘real-world’ situation. A thesis for a combined approach will be set up. This will be the final section of this chapter.
Stage 5 - Defining most significant These will be defined in changes. Chapter 5.
Stage 6 - Taking action. With reference to the general model, we will review the suggested action process. It is noted that this sequence has been adapted from Checkland and Scholes, 2000, p. 62.
4.3 Relevant to agricultural production 4.3.1 The potential to increase agricultural productivity As indicated in Chapter 1 regarding agricultural production (see page 9) and Figure 1.3 (see page 10), whether the intervention is successful depends on collaborative experiments, carried out by small-scale and subsistence farmers with the full support from local, national and 46
international agencies. A way to motivate these farmers to carry out this work, aided by agricultural extension and applied research workers, will have to be found. In this respect the availability of attractive markets for local commodities and the prevention of social differentiation will assist. Here important social and political aspects come into play (see Figure 4.2 on page 44).
Social aspects. The bigger and more advanced farmers, comprising the ‘rich small-scale farmer households’ (see Figure 2.2 on page 21) may tend to dominate the way experiments and pilot schemes are designed and conducted, thereby reducing the ‘poor small-scale farmer households’ or subsistence farmers to virtual bystanders. Avoidance of this will depend on the skill of agricultural extension workers to select those who will take part in the applied research work (see page 81) and act upon its findings. The design of interviews, and the manner in which interviews are conducted, as well as the design of questionnaires by policy-oriented researchers, skilled in Participatory Rural Appraisal (PRA) will be important. Robert Chambers has described PRA as “a growing family of approaches and methods to enable local ‘rural or urban’ people to express, enhance, share and analyse their knowledge of life and conditions, to plan and to act” [my italics (Chambers, 1994)]. This means that well-conducted PRA allows for information gathering and interpretation which ‘conventional’ survey techniques are unable to include. Most importantly however, those undergoing the selection process will be able to have their voices heard. Their awareness and understanding of what is proposed may

Relevant to agricultural production grow. The likelihood that they will play a determining role in the development of the policy which is likely to affect them, may be enhanced. At the same time these proc-
esses question the role and the power of the other ‘actors’ (see Table 1.2 on page 11) involved in the intervention (Thomas et al.,1998, p.151).

PRA approaches will help to understand the social dynamics of these power relations. It can contribute to empowerment for example by: 1.
increasing groups of small-scale have more
awareness and enabling the ‘poor’ and ‘middle farmer households’ to say in defining the needs
and actions related to the intervention; 2.
emphasizing a reversal of power relations between the agricultural extension services, civil engineering services, agricultural experts and small-scale farmers. Following Chambers, 1994, this concerns:

Chapter 4 The Need for a Participatory Approach (a) reversal of frames, through a shift from the categories and values of outsiders to those of the local small-scale and subsistence farmers, enabling them to have a definite input into defining the shape of the investigation; (b) reversals of modes through the use of farmer groups, rather than individual informants; the use of visuals (such as pictures, drawn up by the farmers themselves), rather than verbal techniques; the use of comparison to find out quantitative data rather than direct measurement;
erty trap (see Figure 4.3 on page 47). However, some critical political decisions need to be taken, both by local governments and by the so-called ‘developed nations’ represented in the World Trade Organization (WTO). 1.
(a) allocated funds to infrastructure improvement, especially the maintenance and construction of roads; (b) ensure that the need to make cheap food available for urban populations does not adversely affect the sales price paid at the ‘farm door’ for locally produced foods;
(c) reversals of relations by establishing rapport and involvement with local people, rather than reserve and distance from them;
(c) where necessary, subsidize farm inputs; (d) encourage banks to make seasonal micro-credit facilities available.
(d) reversals of power by enabling local people to build up their capacity for ‘finding out’ and improving their understanding of the ‘problem situation’, rather than investigators extracting information for use elsewhere.
It is realized that this by no means is done easily, a radical change of culture may be needed. Examples of regional changes due to farmers making use of an assured market can be found in sugar cane outgrowers schemes in Kenya, for the Mumias Sugar Estate (Beevers, 1980) and Sri Lanka, supplying the Pelwatte Sugar Company (Private information).
Potentially such reversals can change the ownership of the ‘finding out’ process and cycles of learning. To achieve the transformation stipulated in the RD, a constant dialogue between actors is of main importance.
Political aspects. As pointed out in Figure 1.3 (see page 10), the availability of local and international markets is essential if ‘middle small-scale farmer households’ are to be motivated to endeavour to increase production, and use their ‘trade entitlement’ to move from ‘simple reproduction’ to ‘petty commodity production’ (see Section 2.2 on page 20). The subsistence farmers’ households might find better opportunities to use their ‘exchange entitlement’ by working for someone else thereby beginning to move out of the pov48

Following the above and the information in Section 1.4.1 (see page 9), revised CATWOE elements and RD regarding this intervention of increasing agricultural production, are specified under Section 4.3.2 below. 2.
Achieve and maintain a stable landscape. As indicated in Chapter 2, the longterm viability of local food security depends on a stable landscape. As indicated in Figure 1.4 (see page 13), human activities play a major role,
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Relevant to agricultural production especially with respect to deforestation and desertification.
4.3.2 Setting standards for participation
These activities are management of soil, water and vegetation in such manner that landform (see Glossary) is maintained and an optimum balance between the land areas occupied by respectively arable, pasture and savanna land is achieved and/or maintained.
Mutual relationships
Social aspects. As the achievement and/ or maintenance of a stable landscape is affected by human activities, a PRA is required. Small-scale and subsistence farmers need to be consulted because the balance between arable, pasture, savanna and forest land, as maintained by them, affects both rural and urban populations. There is a need for a common understanding of the problem situation between governmental institutions, technical advisors and representatives of the people living on the land. This common understanding should be translated into a commonly accepted plan and into commonly accepted action. Social and political stresses and constraints are likely to arise as the understanding of the problem situation evolves. The central role played by ‘adaptive management’ is apparent (see Figure 4.5, page 51 and Glossary).
Political aspects. Any project, depending so much on the preparedness of the people concerned to proceed, will require insight into the need for a stable landscape. Figure 1.5 (see page 16) highlights the need for discussion between all groups concerned. The complexity of the process is evident. Power-relations between groups will be important. It will be necessary to determine and commonly agree on who will be empowered to take control action as and when required.
Human activities are central to any endeavour to improve crop production. These activities drive the balance between a stable landscape and food production. Ecosystem processes and plant growth are affected by these activities and as such influence crop production and the stability of the landscape. Overall this interplay takes place within the bounds set by state factors (see Glossary) and economic externalities (see Glossary). The relationship between all groups of the local populations (that is not only farmer groups) and the local and national agencies, can be seen as a main driving factor in any such intervention. This is depicted in Figure 4.4 below. Because ecosystem processes and state factors (see Glossary) affect the level of potential success of the intervention, they are included in the figure, however without further specific comment.
The general concept Participatory learning and action (PLA) between rural people and local, national and international institutions lies at the core of the intervention, its effectiveness depending on that continuous interchange of general views and specific ideas (see Figure 1.2 on page 7). They, in close cooperation, need to set the standards and norms for the intervention. Roles, e.g. social positions recognized as significant by actors in the problem situation, norms, or expected behaviours in the role, and values, or local standards, need to be continually redefined (Checkland and Scholes, 2000, p. 49). In situations such as these, profes-

An active understanding of the mutual interest, converting different interests, represented by groups with power (commercial farmers) and groups with no power (middle small-scale and poor subsistence farmer households) in joined support, is needed if the intervention is to be successful and sustainable.
Reverse learning is defined as learning to offset the gap between outsiders’ knowledge and rural people’s knowledge (Chambers, 1983 p. 84). The behaviour and attitudes of outsiders with respect to farming practices, knowledge of their observable environment by rural people and of their experiments, may be seen as especially important in our context. With 52
respect to farming practices, the scientific bases of minimum tillage, intercropping and shifting cultivation are now better understood than some decades ago. Communities living in diverse environments, and/or which live close to the margin of survival, understand the factors relevant to these circumstances and may use experimentation to strengthen their
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Relevant to agricultural production knowledge. This enormous resource of local knowledge should be respected and used as and when applicable. Chambers (1983) presents interesting examples (his pp. 84-93). One of these is the Groundnut Scheme in Tanzania. The local inhabitants did not cultivate in the areas proposed for that project, but they were not consulted for their reasons. Had this been done, the problems of that particular project might have been better understood.
The emphasis is on a continuous dialogue between local farmer groups and ‘appropriate’ agencies. Representatives of these would need to support the principles of Participatory Rural Appraisal (PRA), and therefore would work from the standpoint of ‘farmer first’ (Chambers et al., 1998). The above is expressed in the revised CATWOE elements of Table 4.1, above and in the RD of Box 4.
BOX 4 (from BOX 1 - page 12) Root definition for a learning process approach aiming to improve agricultural performance. A system to bring about agricultural rural development (P) by developing the productivity of the agricultural sector in a sustainable and equitable manner, while mobilizing and enhancing local knowledge (Y), aiming to achieve a participatory (ownership) rural community and a sustainable rural small-scale farming community, thus contributing to economic development and improved food security for the nation (Z), thereby raising the production capacity of society. This enhancement of local knowledge will be sustainable as farmer groups become motivated to take the lead in building up the knowledge. It is equitable as farmer groups are transformed to come to ‘own’ the processes to be adopted. involvement of local, national and international agencies.
Conceptual model - general The term ‘model’ relates to the ‘real world’ and to the ‘imagined world’. 1.
It should contribute to making increased agricultural production happen.
4.
Different models for the same purpose can be built from different perspectives.
5.
In our case the model should act as a point of comparison in a learning process.
There are two conditions a model must meet for it to be valid:
• as a simplification from what actually happens in the ‘real world’, the essential relations between the parts of a model must allow it to actually work;
• the model must correspond to an ideal relevant to the work of some agency. 2.
3.
The conceptual model under discussion should be such that it can relate to a range of different scales, e.g. micro, meso and macro, that is from local, via national to international levels. This is important due to the

Chapter 4 The Need for a Participatory Approach Conceptual model constructed. This model is presented in Figure 4.7. The points regarding its validity (see page 53) are commented on as follows: 1.
Does this model provide a valid explanation of what actually happens; does it work? The difficulty lies in the effects of the institutional landscape and socio-economic environment in the ‘real world’ problem situation (see Figure 4.6 on page 54). Much effort will have to be devoted to finding the right specialists, a suitable small-scale or subsistence farmer population and agricultural commodity (farming system). If this can be done, the model has a chance to work. If not, the process should be stopped at that stage and a different approach adopted.
2.
This conceptual model applies to local, national and international levels, requiring input from all. Equally, if successful all are affected.
3.
It aims at making increased agricultural production happen involving all concerned in this pressing endeavour.
4.
The question whether the learning process adopted for the model works as a basis for the design of the intervention is answered by analysis E2 as defined in point 12 (see Figure 4.7) which demands that a measure of performance effectiveness be defined.
4.4 Relevant to landscape stability Food security depends on a stable landscape. Small-scale agricultural practice should take this into account at all times. As indicated in Figure 4.3 (see page 47) the stability of a landscape is a factor
56
affecting the achievement of food security in any one area. Small-scale and subsistence farmers are well aware of this, but to put the subject in context the following detail is relevant. 4.4.1 The potential to achieve a stable landscape
General Processes forming single terrain features, are controlled by climate and time. Geomorphic agents (apart from tectonic forces) that cause changes on the earth’s crust are temperature, running water, glacial ice, the wind, groundwater and wind driven water waves. Running water may cause stream or gully erosion. Terrain features may be either erosional or depositional. The former, which is the more frequent landform, refers to the shape of what is left after material has been removed. Examples of these are stream valleys. Sand dunes and deltas are depositional landforms, their shape and size being controlled by a depositional process. Some forms, such as an outwash or delta plain, are partly erosional and partly depositional. These landforms contain a wide range of parent materials of different chemical composition, which in turn are the resources for the formation of soils. This leads to ‘soil patterns’, associated with features of rhizospheres (see Glossary), soil aggregates and mesopatterns perhaps most importantly, the ecological connection between vegetation and soils. From the point of view of a stable landscape, the factors of running water and groundwater may be subject to some degree of control by human activity as soil conservation practices in the landscape. Soil patterns, as the end-results of
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Relevant to landscape stability soil formation processes, are important in the context of terrain features and this is where land use impacts on the landscape. The small-scale and subsistence farmer will be aware of these features when determining which crop to cultivate.

Chapter 4 The Need for a Participatory Approach However, practices of land use can destroy the natural landform, or, in contrast, preserve it in optimal condition. In that context land-use capability classes (see Table 4.2) are of practical use to the small-scale farmer when deciding what crop to cultivate on his/her ‘patch’. In this context and as far as the smallscale or subsistence farmer is concerned, land-use planning is important, particuTABLE 4.2

Lands that can be cultivated safely on a sustained production basis for moderate to good yields of adaptable crops. This class does not require special practices or treatment. Methods of good farming practices for the relevant landform remain essential for sustainability to be maintained.

Examples of such practices are contour cultivation, strip cropping with wide strips, improvement of drainage, removal of rocks or debris, simple rotations, preservation of crop residue.

Under this cultivation method mixed cropping often is used, that is the production or growing of two or three crops together on the same piece of land. The aim is to secure a yield of the highest return possible with minimum weed control and using soil, light and rainfall to the best advantage possible.
58
Permanent cropping Single cropping. In the case of annuals this cropping method entails the crop covering the land for only part of the year, to be followed by fallow. In the case of perennials the land is covered throughout the year by the crop (ILACO B.V., 1985, p. 515).
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Relevant to landscape stability Multiple cropping. This involves the cultivation of two or more crops after each other or with some overlap within the period of one year. The method of double cropping is practised in areas in the tropics and subtropics where sufficient water for crop production is available from rainfall, irrigation or both. An example is double cropping of rice in South East Asia (ILACO B.V., 1985, p. 516).
Intercropping. Intercropping is common and sophisticated within traditional cultures (Innis, 1997, pp. 3, 4). The practice may be used for the period of establishment (maturing) of perennial crops, such as oil palm and rubber. During that period the farmer may inter-plant catch crops (for cash and/or food) which will provide some income whilst the perennial crop is still unproductive. This points to a more efficient use of the available solar energy than would have been the case with the farmer concentrating on a monocrop only. However this improved efficiency (inputs over outputs) of solar energy used also can be achieved with annual crops, such as those of intercropped maize and beans. This is due to the different growth habits of the two plants. Maize has more or less vertical leaves which trap about half of the available sunlight. The lower and more horizontal leaves of beans are able to capture most of the remaining solar energy. Experiments show that, using the same resources of water and light, intercropping, used intelligently, can produce a higher yield of organic matter, or food, than monocropping can (Innis, 1997). A further aspect is that the traditional farmer, by intercropping with legumes, adds nitrogen to the soil.
Water-borne erosion
Water-borne erosion depends on the unhampered impact of raindrops on the soil, causing a detachment of soil aggregates and surface run-off.
Rainfall. The unhampered impact of raindrops on the soil results in detachment of soil aggregates, causing surface run-off, or water-borne erosion. Run-off is the part of water falling on the soil, which does not enter into the soil. Due to the slope of the land, it runs off the surface, carrying soil particles and aggregates (water-borne erosion) with it.

In this context the following factors are important:
• Energy of the rainfall The kinetic energy of the falling raindrops is the most important factor. A drop falling on bare soil surface may

duration saturate the topsoil with water. This decreases the stability of the topsoil, thereby promoting run-off and erosion. If the moisture is well distributed in the soil matrix, the soil can cope more readily with the hazards, resulting in less erosion.
• Quantity of the rainfall Higher quantities of rainfall increases erosion hazards. Showers of long TABLE 4.3

• Intensity of the precipitation With intensities of 3-60 mm/h up to 10% of the rain is erosive, whereas if this is higher than 100 mm/h all rainfall is erosive (ILACO B.V., 1985, p. 447). Due to higher intensity of rainfall in sub-tropical and tropical areas than in temperate areas, erosion hazards tend to be higher in the former areas. The nature of the soil. The natural characteristics of the soil, soil management by humans and various climatic factors affect its erodibility. The structural stability of the topsoil and its organic matter content are important. A topsoil of a non-stable structure disinte60
grates rapidly. Raindrops cause a puddling effect, promoting surface run-off. The soil profile depth also is important. A deep profile (subject to there not being horizons impeding water movement) can lead to a good water holding capacity, reducing the risk of over-saturation of the topsoil.
Slope. If the slope of the land is sufficient for water to run down it, the land may be subject to erosion. On steep slopes, excess water from precipitation will run down that slope at higher velocity with higher kinetic energy, than on a gentle slope, causing more serious erosion. The longer the slope, the more excess water will accumulate on it and all this will run down the slope at an ever increasing vol-

Relevant to landscape stability ume and velocity. The curvature of the slope, the vegetation on it, its texture and structure are factors coming into play (ILACO B.V., 1985, p. 449).
Vegetation. The cover of the soil by vegetation breaks the energy of raindrops, and increases the surface retention. This is a most important factor in reducing run-off (see Table 4.3). Forest and good grassland form the best soil cover. Good management also is a substantial factor. All this is of considerable importance when it comes to cultivation practices (see Chapters 5 and 8).
Wind-borne erosion This type of erosion refers to the action of wind detaching, transporting and
depositing soil. As soil needs to be dry to undergo this action, areas sensitive to this type of erosion are characterized by low seasonal rainfall and a climate of high temperatures. Unhindered impact of a strong movement of air on smooth soil surfaces, is a prerequisite. In desert areas, already comprising extensive areas of relatively loose soil, the damage to the area is limited. In arable land on the other hand, extensive damage can be done by the complete or part removal of the arable layer. As wind erosion does not need a slope, wind action removes soil from flat as well as from sloping land, provided there is an open and smooth soil surface.
FIGURE 4.10. Gully erosion. Photo HB.
Under such conditions the very fine particles (<0.1 mm diameter) are moved in suspension by air turbulence and then may move over considerable distances. Such dust storms can remove the richest part of the soil. The medium sized particles (0.050.5 mm diameter) move by bouncing over
the surface of the land. The coarsest particles are blown over the land surface, causing so-called creep of deserts. These medium and coarse particles may damage vegetation and cause abrasion, breaking soil aggregates into smaller erodible sizes (ILACO B.V., 1985, pp. 452, 453).

Chapter 4 The Need for a Participatory Approach Types of erosion Sheet erosion. During this process topsoil is more or less evenly removed by water or wind. Sheet erosion can be recognized by: • thin topsoils and subsoil exposure; evidence may be seen by light coloured patches of soil; sometimes this type of erosion may have progressed to the extent that bedrock is exposed; • relatively high amounts of coarse materials, such as coarse sand, gravel and pebbles in the arable layer, due to the finer material having been blown or washed out; • exposure of roots;
• deposits of materials at the leeward side of a field.
Micro channel or rill erosion. This is characterized by small washes in defined channels which still can be filled by normal cultivation practices (see Figure 4.9 on page 59). When run-off water concentrates in rivulets of sufficient volume and speed to leave small incisions in the land surface, rills occur.
Gully erosion. This is concerned with the removal of soil by excessive concentration of running water, resulting in the formation of deep channels which cannot be removed by tillage (see Figure 4.10 on page 61). A rill can be cultivated and therefore handled or passed by farm machinery. A gully cannot. If not dealt with, gullies can become so extensive as to making large areas of land unusable. Then it threatens land and roads and river courses. The final result of such unchecked gully erosion is the total devastation of the landscape.
62
Deposition and accumulation. When soil is removed from a location in an uncontrolled manner, it will be deposited elsewhere in an equally uncontrolled manner. • Deposits from water-borne erosion Layers of sand, silt and mud may affect agricultural land when deposited downslope from eroded areas, thereby destroying crops and damaging the land. Discharge (drainage) capacity of the river system may be reduced as a result of being loaded with suspended fine soil particles, promoting flooding of surrounding areas. Due to its kinetic energy, the mass of flowing water will tend to establish a new hydraulic equilibrium, by changing the geomorphology of the river system. Scouring the riverbed in one area (say the outside of river bends) and raising it in another (say the inside of river bends) are examples. Such raised riverbeds will lead to further drainage problems, due to increased natural water levels. Also water discharging structures in the river system, such as weirs and flumes may become blocked, as a result of which water storage reservoirs will silt up. This disturbance of the hydraulic balance of the catchment area produces strong discharge fluctuations of the rivers into which the catchment drains. Higher flood levels and stronger discharges occur. In the downstream areas alluvial sedimentation, such as the alluvial deposits being transformed into flood plains and river delta areas, may have beneficial effects by enhancing agricultural productivity and potential for settlement (ILACO, B.V., 1985, pp. 452, 453).
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Relevant to landscape stability • Wind-blown deposits Large quantities of wind-blown material may adversely affect both agriculture and the area where deposition occurs. Such deposits are characterized by their rather uniform mechanical composition and sedimentation pattern. Shifting sand dunes in (semi-) desert areas are of a typical pattern. By covering the land and blocking canal systems they endanger oases and irrigation schemes, thereby reducing the quality of the land and in fact making irrigation impossible. On the other hand, deposits of thin layers of loess-like material by dust storms can improve the quality of the land when this occurs year after year (ILACO B.V., 1985, pp. 452, 453).
Soil conservation This concerns action to prevent or control erosion and is important for the smallscale farmer. If successful, damage to the land may be avoided, thus preventing financial loss due to crop yield becoming depressed as a result of erosion. Preventative measures, such as applied crop husbandry techniques, can be taken by farmers themselves. Such measures do not require complicated planning, engineering or high capital investments. However to produce best results, land use will have to be planned (ILACO B.V., 1985, p. 454).
Soil conservation plan Factors to be considered are precipitation, soil conditions, topography, present land use, including its vegetation, and people. An assessment of these factors might produce an evaluation of the actual erosion symptoms, the erosion hazards involved and how these might be dealt
with. Based on this evaluation, the land may be classified according to its ability to produce a sustained yield by means of specific uses and treatments. The natural conditions of the land will impose restrictions affecting the intensity of land use, the corrective soil conservation practices to be used and the productivity of the land. In our context, which concerns the management of agricultural production on mainly small-scale and subsistence farms, as opposed to large scale mechanized commercial agriculture, small-scale farmer groups should be aware of the eight-class land-use capability classification devised by the USDA, shown in Table 4.4 (see page 64).
Conservation and reclamation measures These measures should be designed in such a manner that they can reduce or eliminate the erosive energy held by water and wind. The important actions to be taken, based on the soil conservation plan, should be seen as one-time investment, concerning, should this be necessary, major control practices and equally importantly, year-round and therefore repeated routine cropping and management practice.
Major control practices. These can be seen as mechanical and biological protection practices and artificial protection works.
• Mechanical protection Earth works which aim at controlling and diverting run-offrun-offrun-off in arable areas are a form of mechanical protection. This type of defence against erosion building up starts with the construction of a stormwater diversion drain, intercepting water flowing

The run-off control achieved by this drain must be effective, the structures further down depend on it. In the arable land run-off is controlled by channel terraces. Generally speaking, these are built mostly on a slight TABLE 4.4

grade or, where practical, along the contours of the lands. Depending on the rainfall, slope and soil conditions, distances between channel terraces vary and can be constructed as broadbased or narrow-based terraces. The broad-based terraces can be incorporated into a cropping pattern.

The excess water from the stormdrain and terraces should be discharged into a water course which may be either natural or artificial, the latter mostly as grass waterways, discharging into natural drains of the catchment areas. If gullies are used for that purpose, they need to be reclaimed if uncontrolled run-off is to be prevented. In addition to vegetation, structures such as gabions, wire bolsters, netting dams, brushwood dams and log dams can be used to slow down the speed of flow in such drains. Rather steep natural slopes may be converted by constructing bench terraces. These comprise nearly horizon64
tal ledges and vertical walls between the ledges. In stable soils these walls are secured by vegetation, but in less stable soils structures with stones, brick or timber will be needed (ILACO B.V., 1985, p. 456).
• Biological protection Vegetation, breaking the kinetic energy of raindrops is the main vehicle for this purpose. In this regard the following aspects are of interest.
Reforestation. If land is not or no longer suitable for agriculture, reforestation should take place. Provision of a creeping ground cover is most important during all stages of reforestation.

reduce wind velocity to prevent removal of fine soil particles by air turbulence. However, this raises a potential problem. If a windbreak is constructed of a dense row of relatively high trees, this will break the wind force, but serious turbulence just behind the trees may occur, increasing the problem in the trees’ influence zone. A windbreak which is sufficiently permeable to prevent that problem arising, comprises a balanced composition of shrubs, medium-high and high trees. Where the control of wind as well as that of water erosion is needed, windbreaks may be complemented by hedges planted at given distances along the contour lines.
Pasture establishment. The soil type and climate may offer opportunities for the establishment of pastures on reclaimed land. This may be the case especially when conditions are regarded as too risky for arable cropping, but too attractive to leave the land to establish a climatic climax vegetation (see Glossary). As shown in Table 4.3 (see page 60) a well established pasture of a correct mixture between grass and legumes, provides good protection against water erosion.
• Artificial protection works Increased erosion risk on land which may be exposed as a result of works needed for the construction of roads, culverts and viaducts, can be considerable. In such cases in erosion-sensitive areas, planted vegetation may not establish itself sufficiently quickly to provide adequate ground cover to prevent erosion occurring. The seeded sloping land should then be covered by
Cropping practices. This concerns the practices of crop rotation and strip cropping. Especially in areas vulnerable to erosion, crop rotation is a useful practice if sustained crop production is to be achieved. Under such vulnerable soil conditions certain crops will have to be left out of the rotation, or grown to a limited extent only. Although this may be restrictive from a production and income point of view, it is essential to protect the soil surface against erosion at all times, if long-term income is to be sustained. Strip cropping concerns dividing land into alternate strips of erosion-resistant and closely grown vegetation, such as grass, grass-legume mixture, small grains or natural vegetation, with economically important crops, which, however, are not suitable to control erosion. Examples of these economically important but erosionvulnerable crops are maize, sorghum, cotton and root crops. The practice of strip cropping generally is applied in combination with tillage and soil conservation practices. Diverse ways of strip cropping are:
• Rotational field strip cropping Alternate strips of equal width, that is some 10 to 20 m, are planted or natural grassland is left in place. These strips are rotated at regular intervals. The technique is constrained by the slope of the land, which should be not more than 5%. Field strip cropping can be done manually, but should machinery

be used, the width of the strip should be a multiple of the width of the prime mover employed.
• Buffer strip cropping Here permanent grass strips vary with arable strips. The grass strips can be rather narrow at some 3 m, whereas the arable strips, depending on the conditions of the land under cultivation, may vary from 10-20 m. It is advisable to adopt a layout with the grass strips along the contour.
• Contour strip cropping Under this system crop rotation is done on the strips and cropping follows the contour as closely as feasible. To bring about the correct layout,
66
skilled personnel are required and farmers have to be skilled in performing the cultivations as needed. Due to its crop rotation this form of strip cropping can be very effective for soil and water conservation purposes. The application of manure or fertilizers and perhaps above all the use of cover crops is facilitated. The width of the strips continues to be dependent on the local conditions of soil, climate and slope. Here too, should farm machinery be used, the width of the strips should be some multiple of the width of the ‘footprint’ of that machinery.
• Wind strips This concerns the planting of farm crops in straight and parallel strips, in

Relevant to landscape stability a direction at right angles to the direction of the prevailing winds. The contour is disregarded. These wind strips can act as a support to windbreaks. To encourage the roughness of the soil surface, stubble should be left on it.
General observation. To practise soil conservation methods successfully, a topographical survey, with contour lines at an established vertical interval, is required. The extent of that interval will depend on the slope of the landform. Skilled personnel are needed to carry out this work and advise on the control practice to be adopted. Where necessary, assistance with the implementation of that practice may be needed also. As a soil conservation plan has to be based on factual information, collection of that information relies on investigation and research. As rainfall, soils and slope of landforms will differ over relatively short distances, the direct and pertinent involvement of local farmers’ groups with that research is relevant. Carefully consulted and selected farmers’ groups from small-scale as well as from subsistence farmers should undertake field work on say, a picked test plot, or (where at all possible) a whole arable field. During the course of that research, quantitative measurements should be carried out in the field to determine (a) the run-off of water in relation to rainfall, soil and slope; (b) the removal of soil in relation to precipitation and slope; and (c) gully development and extension.
Tillage operations The success of control practices, discussed above, will depend on tillage practices facilitating such control. In this regard the following tillage operations are appropriate.
• Contour tillage Tillage and cultivation practices are carried out along the contour in combination with contour strip cropping. When ridges and furrows are laid down along the contour, rainwater collected in those furrows will not be able to run down the slope. Crops, due to improved soil moisture holding capacity, may tend to develop more quickly. Once canopies have closed, the land will be better protected, with fewer gaps in the crop stand. The difficulty may be to design the ridges in such a way that the heaviest rainfall is blocked from running down the slope and water has the opportunity to infiltrate into the soil. If this is not the case ridges might break during a rainstorm, resulting in serious damage. Local knowledge with regard to the height of ridges and frequency of occurrence of such rainstorms will be vital.
• Minimum tillage As a stable soil structure is most important to counteract the erodibility of the soil, intensive tillage should be avoided as much as possible. If the socalled plough zone of the soil is sufficiently friable, it may be possible to adopt a plough-fertilizer applicationplant method, reducing work to a single pass of equipment. In this context the conservation of trash from a previous crop is relevant as this reduces the impact of rainfall on open soil. Vertically mounted discs can cut through the trash, the discs set at an interval to accommodate the plough-plant operation.
• Removal of rills When the first stage of erosion has occurred (see page 62), rills can be

67
Chapter 4 The Need for a Participatory Approach removed by tillage operations. However, the aim of soil conservation tillage operations should be to minimize the chance of rill erosion occurring.
• Chiselling Chisel ploughs, rather than disc or mouldboard ploughs which turn the soil in the plough zone, burying trash (and weeds), should be used, perhaps especially on land susceptible to wind erosion. The activity leaves the surface of the land in a rough cloddy condition preventing wind erosion.
Soil conditioning When soil structure is not stable, slaking of aggregates (which may be the result of performing some land preparation activity under wet conditions) seals the soil pores in the soil surface layer. As a result runoff commences. The maintenance of structural stability is most important and for that purpose a good supply of organic matter is necessary. In that context the following is relevant.
• Mulching As indicated in Figure 4.11 (see page 66), trash may be left on the land after harvesting. When, on the other hand, there is only stubble, this can then be chopped up and spread over the surface of the field, protecting it against rainfall and wind. Decomposing mulch will tend to improve the soil structure. When mulch hampers seedbed preparation, a tool such as in Figure 4.11(a), or chisel ploughs can be helpful in preference to mouldboard ploughs. In small-scale or subsistence farming practice, farmers, as members of a farmers’ group, might be able to assist each other by spreading con-
68
served trash manually and sometimes propagate crops simultaneously.
• Leys These are perennial, non-permanent pastures comprising grass mixtures, grass-legume mixtures or legumes. They can be incorporated in the crop rotation: a very useful practice as soils under grassland tend to promote the development of a root mat, leading to a granular structure. If, in the overall management of crop rotation, leys can be kept in position for a period of some four years, the organic matter content and related biological activity in the soil in the root zone may well have improved. Once the ley crop is ploughed under, it is likely to have a beneficial effect on the structural stability of the soil and its productive capacity for a number of years. Furthermore leys provide a good ground cover during the time they are in place. They can be grazed or harvested, providing good fresh or preserved cattle fodder.
• Fertility improvement A useful practice to achieve an improvement in soil fertility (see Glossary) constitutes the adding of farmyard manure. This, due to its organic compounds, promotes biological activity and soil structure, whilst its mineral composition improves the fertility status of the soil. Another useful practice can be the addition of lime. Due to its calcium content, it can have a favourable effect on the stability of soil structure. However, as the calcium ion will tend to remove magnesium, sodium and potassium from their exchange sites in

This type of action may well be beyond the financial ‘carrying’ capacity of the small-scale and subsistence farmer.
Land degradation - general observation Land degradation is a function of the degradation of vegetation, water resources and soils. Climate change plays an important role, as does a lack of human interest in the correct and productive use of land. Rapid deforestation, causing changes in the global water cycle, is an example of this. Amongst these factors, soil degradation is one of the most important as degrada-
tion of vegetation and water resources could be seen as its consequence. The components of soil degradation are (a) chemical processes of leaching and volatilization, (b) physical processes of compaction and erosion, (c) biological processes of oxidation of organic matter and a loss of biodiversity (see Figure 4.12). Declining yields and poor responses to inputs are important factors of consequence. Land degradation can play a most important if not vital role in the context of food security. 4.4.3 Root definition and conceptual model
Root definition Section 4.4.2 provided information regarding a number of issues and practices in the context of maintaining landscape stability. As these also influence the degradation of water resources and vegeta-

community to be decisive in this way, the process will be ‘owned’ by them, an aspect regarded as vital for its longterm success. If this cannot be done, a more prescriptive approach should be adopted.
The CATWOE elements on which this root definition set out in Box 5 is based are stated in Table 4.5. The important element here is involvement of local smallscale and subsistence farmers and soil conservation specialists, working together to develop a soil conservation plan. The drivers for that plan are the conclusions derived from the farmer-led applied research regarding soil water holding capacity, run-off and the deposition of soil materials.
Conceptual model constructed. A conceptual model regarding the achievement of a potentially stable landscape is shown in Figure 4.13. With respect to the validity of this model (see page 53), we comment as follows: 1.
Can this model, as a simplified description of the overall problem situation work? Very similar to what has been stated regarding the model for the improvement of agricultural performance (see page 56), much effort will have to be devoted to finding specialists in terrestrial ecology, land and soil survey and perhaps above all, soil conservation practices (see Figure 4.8 on page 57). These people would have to ‘pool’ their insight into the problem situation and be prepared to bring the active participation of the rural (and small farming) population into the preparation of any field research, and have this led by representatives of the local population. This depends on a participatory learning and action (PLA) approach. By empowering the local
A potential point of stress is a possible conflict between the interests of the technical people in the field who may wish to bring about the implementation of a successful project and that of the donor agencies. The former, working under PLA have downward accountability to (their) small-scale and subsistence farmers and upward accountability to supervisory staff. The latter perform under upward accountability to agencies supplying or lending resources, such as money and technical supervisory staff. The wish to deliver a successful intervention should be an adequate driver to overcome potential problems arising out of such conflict. 2. The model therefore requires input from all, that is on a local, national and international level. If successful, all will benefit. 3.
As it involves all in the process, it aims at making the achievement of landscape stability more likely.
4.
The question of whether the learning process adopted for the model works as a basis for the design of the intervention is answered by analysis E2 as defined in point 12 (see Figure 4.13 on page 72). This demands that a measure of performance effectiveness be defined.
These deliberations form the basis to define strategies for small-scale agricultural development, guided by a research process, presened in Chapter 5.

For the discussion in this chapter Figure 5.1 (repeated from Figure 1.2, see page 7), which represents the core concept, is useful. It leads to the conclusion that local and international agencies, such as governments, NGOs and farmers’ extension services, in conjunction with small-scale and subsistence farmers (here, more specifically subsistence farmers’ groups) have the potential to affect rural livelihoods. In the process of delivering the aims of improved agricultural productivity and landscape stability, there is an ongoing interchange between rural and urban populations instrumental in setting strategy. In this regard strategic questions about

what is important, what are the available choices, what needs to be changed and how this can be achieved,
need to be considered. NGOs operating in the ‘expert environment’ (see Figure 3.4 on page 41), may have to carry out a feasibility study, in order to decide a strategy on which further progress would be based. This chapter endeavours to follow the ‘doing’ points in Figures 4.7 (see page 55) and 4.13 (see page 72) in order to come to a practicable project.
5.2 Finding out what changes are needed The aim is to define the most significant changes, necessary if the model given in Figures 4.7 and 4.13 is to work in a socio-political environment. 5.2.1 Research questions When comparing the systems developed in Chapters 1 and 3, and their conceptual models with the ‘real world situation’, the focus of inquiry would be on the viability of the activities, or projects, by fully involving local small and especially subsistence farmers. The stated aim is to achieve landscape stability and increased agricultural production, leading to food security for these farmers. Action in this regard would need to be based on the results of research about the policy area, which is the promotion and use of PLA in the intervention of increasing food production and improving landscape stability. The research process pathway, leading to conclusions, is summarized broadly in Figure 5.2. The research questions, and 74
hypotheses on which they are based, are summarized in Table 5.1. They depend on the specific aims of the project, which lead to the information needed to find an answer to the questions. The definitions of the central and subsidiary questions have to relate to the readiness of the ‘user-stakeholders’ to take part in the intervention. This is so because small-scale farmers in the WDRs under consideration, live under vulnerable conditions. They are exposed to an environment with unreliable, or unstable natural resources, such as rainfall, soils and topography. Frequently, also, this environment is politically and/or economically unstable, as a result of which especially the small-scale subsistence farmers will have an overriding interest in firstly protecting their own livelihoods. The question to what extent these subsistence farmers would regard participation as important in the context of a commitment from outside agencies to bring in something new, technical or otherwise, forms the background. It may become apparent that subsistence farmers may wish to take part only in membership groups, defined as “people’s associations which undertake voluntary collective action and self help” (Uphoff, 1995, p. 17). From this it follows that the project, or intervention, cannot be defined clearly without first having insight, or understanding, the socio-economic and sociopolitical conditions of the rural area(s) in which the project is to take place. In other words is it possible to form these membership organizations in these low-income and underdeveloped areas? The research questions and hypotheses, stated in Table 5.1 refer to the central research question and subsidiary questions. The central question relates to the

Central
To what extent are PLA and PM&E taken into account in the design of agricultural development projects specifically aimed at improving food security?
The sustainability of an agricultural development project will be enhanced by attention to downward accountability to and participation by the people directly affected by it.
Subsidiary 1
What would the effect of PM&E be on the economic viability of such agricultural development projects?
The economic and social viability of a project will be enhanced if PLA and PM&E are adopted at the design stage.
Subsidiary 2
How would the subsistence farmers in the project area react to the policy of using PLA?
Given the opportunity to participate, the local people affected by the intervention will support it.
Subsidiary 3
What if the subsistence farmers affected by the intervention were given the opportunity to effect/change the policy by themselves, using PM&E?
The people affected by the intervention will wish to participate in the design of the project, provided they see the opportunity for capacity building.
PLA: participatory learning and action; PM&E: participatory monitoring and evaluation.
What is important? From the above it is concluded that it is important to establish that small-scale subsistence farmer groups indeed want to take part in the effort, initiated by ‘outside agencies’, to achieve a (more) stable landscape, whilst adopting techniques aimed at protecting the soil and landform and increasing food production.
What are the available choices? If the enquiry leads to the conclusion that this is so, the collaborative effort should be set in motion. If the situation is uncertain, work should continue in the realization that failure is possible. The subsidiary questions 1-2 and their hypotheses (see Table 5.1 above) centre on these possibilities. On the other hand the subsidiary question 3 entertains the situation (perhaps unlikely) where subsistence 76
farmer groups firmly oppose collaboration from outside, whilst being prepared to use PM&E. In that case the matter should be left with them, after they have participated in the design of the project. This potentially more difficult situation should be based on an agreement between the ‘owner shareholders’ (see Table 1.2 on page 11 and Table 1.3 on page 14), about what is feasible. 5.2.2 The questionnaire suggested for the research As indicated in Figure 5.2, the information needed may be collected from ‘experts’ by means of questionnaires and focused interviews. These are used to confirm that the world view that ‘bottom-up’ control and participatory management is essential for success, is shared by the ‘experts’ initiating the project.

The first two questions in Table 5.2 (see page 77) consider the alternatives of a blueprint method, e.g. an intervention and implementation model to achieve change, or alternatively a learning process approach. The conceptual model shown in Figure 3.4 (see page 41), could act as an aid to compare the concept with conditions pertaining in the ‘real world’. The questions 3 to 10 in Table 5.2 concern the involvement of local stakeholders in the design and implementation of the project and relate to the second and third 78
subsidiary questions of Table 5.1 (see page 76). Answers to the first two questions may be found from the discussions based on the questionnaire and interviews. The usefulness of the outcome, referred to in the subsidiary questions in Table 5.1, depends on the reaction of the subsistence farmer communities.

5.3.1 Introduction
Following the conceptual model of Figure 2.4 (see page 41), the various activities to be carried out are indicated in Table 5.3 (see page 78).
As has been mentioned above, when seeing the two approaches of blueprint and PLA respectively as ‘ideal type’ concepts, it seems unlikely that agricultural projects, aimed at achieving sustainable landscape stability and increased agricultural production, following those individual ‘ideal’ concepts, will succeed. This is largely due to the socio-political environment, which may not promote effective participation. ‘Effective participation’ refers to the power and the right of people to use that power to shape decisions which affect their lives. When they cannot exercise this right, women and men are disempowered (Eade, 2000, p. 4). This therefore means that in the socio-political environment (see Figure 3.4 on page 41), the state, as represented by government institutions and civil society, in which “social movements become organized” (Eade, 2000, p. 5), must promote conditions in which this empowerment can take place. An effective market, which small-scale and subsistence farmers can access to use their endowment of exchange entitlement for the purpose of trading (see Sen and Drèze, 1999, p. 7) their produce, is an essential part of this. In fact the three spheres of state, market, and civil society interface to evolve towards a democratic society. For our purpose however, subsistence farmers must have access to an effective market, if they are to be motivated to ‘grow’ from their direct entitlement (producing for their own needs only) towards having an exchange entitlement available. Once such open markets are available, small farmers may be motivated to take part in this
5.3.2 Activities
Expert environment The process is initiated in the ‘expert environment’, where firstly a feasibility study is conducted. This study concentrates on the socio-economic environment, endeavouring to assess variables such as the trends of per capita income and human development indices (HDI) in the area or region under observation. Economic resources, affecting economic development or economic stagnation in the long term are an important part of this study. However, economic development is not considered on the bases of such economic factors alone. In order to arrive at some strategy factors, on which the approach to the project is to be based, historical, cultural, demographic, political and social factors should be included. Furthermore, ecological factors are of great importance when considering the potential for a successful implementation of a development project.
Socio-political environment The historical, cultural, demographic, political and social factors come into play when assessing the population involved in subsistence farming and small-scale agriculture. Based on the information generated by a feasibility study and by their assessment of the socio-economic environment, ‘experts’ draw up an outline draft-project. This, at some stage during the process of
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
79
Chapter 5 Researching the Situation to Define Strategies setting up the project, will have to be discussed with small-scale and subsistence farmers (groups) to obtain their willingness to lead research. In that context an open and direct discussion between stakeholders, that is between the initiating outsiders and local farmers will have to take place. With Guijt (1998, p.13) important factors to be taken into account are:
• Fluctuating intensity of involvement It is likely that there will be a fluctuating intensity of involvement by different groups over time in a range of monitoring tasks, such as data collection, analysis and dissemination.
• The distinction between outsiders and local farmers Some in the same group may offer a high level of participation, others in that group may offer none at all, thus remaining ‘outsiders’. Differences in power and influence exist between landed and landless farmers, female and male farmers. For instance it is most important that women farmers be involved in the monitoring process (see Figure 3.4 on page 41).
• The levels of participation The local political context is likely to strongly influence what may be regarded as a feasible intensity and the manner in which local subsistence and small-scale farmers take part. As the local small-scale and subsistence farmers will be the people managing ongoing innovation and change, they must be involved in the process of technological development and implementation of the project. As not all farmers will be interested to the same degree or able to participate in all aspects of the process
80
laid out in Figure 4.13 (see page 72), the discussions referred to here need to establish the levels at which participation would occur. The following presents an example (Guijt, 1998, p. 14).
• A core of, for example, 10 farmers These come from farmer groups and have volunteered to become involved in strategic planning, data analysis of farmer-based experimentation, and designing/implementing the monitoring and evaluation process.
• Some 80 farmers These comprise women and men, including community leaders and individual subsistence farmers. They are involved in joint experimentation, for instance regarding minimum soil tillage for soil conservation purposes, and/or intercropping crop production practices. Important aspects of their work is to be involved in key times of monitoring, evaluation and planning.
• General farming ‘public’ and community associations. Activity-specific collaboration with these groups is undertaken. This general farming ‘public’ and community associations should entail at least some 30 communities and 400 to 500 small-scale and subsistence farmers, ready to adopt participatory measures. The monitoring/evaluation findings of the experimental work will be shared with them as a spring board towards the wider community.
Farmer-led research and experimentation. A model on which a combined approach could be based is shown in Figure 5.3 below. In the context of agricultural development to achieve food security and landscape stability, this looks

at socio-political and economic empowerment, regarded essential for economic growth. Agricultural extension workers, selected for their ability to work according to a ‘people-first’ and ‘farmers-first’ approach (Burkey, 1993; Chambers et al.,1998), get involved with local subsistence and smallscale farmers along the lines indicated in the previous paragraph. They work with these selected people, and learn from and
with them from the farmer-led research, through its monitoring/evaluation process (see below). As the extension workers train a core of small local farmers, for instance in the use of soil conservation practices, these small farmers, and their farmer organizations, which are funds of local knowledge, strengthen their ability to change project identification and design. This then is applied to the farmerled research in which say some 80 farmers
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
81
Chapter 5 Researching the Situation to Define Strategies (women and men) take part. This increases the local knowledge underlying the research. In the socio-political environment this increases pressure towards good governance and allied economic development. If this repeated circular process is successful, potentially it could lead to a more stable small-scale farming community, by means of farmers discussing results of their work with the wider community. Evaluation of the experiment (involvement of the 80 farmers) may point to a desirability to set up a pilot scheme, involving a wider community of some 500 farmers, including the 80 farmers. Once approved by funders, such a scheme might be set up by that, approximately 500 members strong, farming community. Their specific monitoring and evaluation of the pilot scheme might lead to the design, again with their involvement, of a demonstration plot, which they would monitor, evaluate and control. This produces increased local knowledge and increased influence in project design and therefore economic empowerment. This means that if the demonstration plot, upon evaluation by the farmers, is found to yield unsatisfactory results, the process can start again. Training by extension workers of ten local farmers would make use of their increased understanding and know-how, leading to a new experiment, pilot scheme and demonstration plot. If the demonstration plot is successful, funders, local institutions and farmer organizations, with ongoing monitoring, evaluation and control by farmer representatives (where possible the ten ‘original’ farmers) and extension workers, would enlarge the area under the revised production model, which should promote 82
a stable landscape, as well as increase and sustain food security. This would have a chance of contributing to economic growth.
5.4 The monitoring system An effective participatory indicatorbased monitoring system lies at the core of a successful PLA agricultural project. 5.4.1 Introduction From the above may follow that activityspecific monitoring, evaluation and the taking of control action by stakeholder user-owners, is vital if the sustainability of the agricultural process is to be ensured. Once user-owners, as designers of the project (and therefore model builders) are fully committed to the project, and a decision has been made to undertake it, measures of performance indicators (see Glossary), central to the monitoring process have to be defined (see Figure 3.4 on page 41). In this context, a clear definition of the aspiration, or expectations of participants should be regarded as essential. 5.4.2 The fundamental strategic steps Following Guijt, 1998, the fundamental steps needed to set up a participatory indicator-based monitoring system are discussed below. It is noted that these steps are not necessarily taken in the stated sequence. For example the selection of ‘indicators’ follows from the formulation of ‘objectives’, whereas clear indicators assist in the formulation of objectives. 1. Decide to undertake a participatory monitoring system. As this participatory process involves a fairly sizeable group of people with
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
The monitoring system different interests and views, it will take time to come to agreement. As long as project staff are prepared to accommodate small-scale and subsistence farmers’ views, it should be possible to arrive at workable compromises. If, however, local people convince the ‘expert initiators’, that this is against their interest and a waste of their time, the project should not be started. 2.
Identify participants. List the people who are involved with the agricultural project aiming at achievement of a stable landscape and increased production. Invite all relevant groups/farmers to take part in the monitoring and find out who has the essential knowledge/understanding of reading/writing and/or crop production technology.
3.
Identify expectations. Find out what people hope to get out of the monitoring system. This might elucidate the extent to which people or groups are willing and able to take part in the different tasks. It might bring out who would like to be partners in the project and motivate people to work systematically. As equal interests in the different tasks to be performed cannot be assumed, it will be necessary to re-assess who participates in the process on an ongoing basis.
4.
Clarify (or identify) objectives. During the earlier planning phase clear objectives (see Glossary) of the work to be monitored must have been formulated, such as for instance “increased overall yield level of a Pigeon pea and Pearl millet intercropping system, under a given moisture availability regime” or for an irrigated
rice crop farming system “improved water use efficiency of irrigated rice production”. Such objectives must be available to all in written form. Time should be given to discuss these and ensure that they are understood and agreed by the different groups and people involved in the monitoring process. In that context objective criteria should be brought to the fore, such as for instance 4.1 On what basis would you find improvement acceptable? Local participants may consider the effort and costs to achieve the improvement is beyond the capacity of the community. 4.2 What specific standards of care (landform, soil, water and crop management) are needed to ensure that the improvement is achieved? This relates to the capacity of the people involved with the project to do the work needed. 4.3 By what standards do we assess whether our operation is environmentally acceptable? During the monitoring process objectives (and criteria) may change, but involvement by all concerned will tend to strengthen commitment (and morale). 5. Identify and select indicators. Objectives can be measured with different indicators (see Glossary). As the setting up of too many, ambiguous or irrelevant indicators should be avoided, their identification requires attention. Their choice will depend for instance on the availability of relevant data. To make sure that the indicator

Chapter 5 Researching the Situation to Define Strategies can be used is to see to it that it is ‘SMART’ (Specific, Measurable, Attainable, Relevant, Timely). See ‘Indicators’ (page 85). 6.
Selection of method. The method used to collect and register the information, depends on the indicators, the time available, skills of the collectors, the technology and resources. The important point here is that monitoring requires that assessing and recording of information takes place for each indicator used. See ‘Methods’ (page 90).

Determine frequency, timing responsibility of monitoring.
• when will this happen (frequency, day / week / month). 8.
To ensure that they are relevant and practical, test the methods and tools to be used. They must be feasible to apply. The people who will do the monitoring may require training to enable them to be confident that they can do their work to the standards needed. 9. Systematic implementation of the monitoring calendar. To understand what changes are occurring when and where, it is important to be methodical in the collection of data. If one is to obtain an understanding of cause and effect, systematic monitoring work is essential. At the same time, flexibility is required in that it may be necessary to adjust methods or indicators if they do not provide accurate and reliable information. External factors may change. This means that ongoing scrutiny of the information and validity of methods should take place during the process of monitoring.
and
Guijt, 1998, further highlights that the frequency of measurement depends on the rate of change of the indicator. For instance, if weather is to be measured, daily measurements will be needed. On the other hand, if changes in attitude towards the use of pesticides are to be assessed, once every 6 months might do. If soil loss is to be measured, frequency will depend on the frequency and timing of rains and wind. It is essential to clarify the following questions and compile the answers in an ‘annual monitoring calendar’:

Using the information.
Each relevant group should use the data to solve problems for the planning of future activities. The findings of the monitoring process may be used to revise the objectives/plans/projects of the farmer-led research. This involves the taking of control action (see Figure 3.4 on page 41). (Source: Guijt, 1998, pp. 22-26.)
5.5 Indicators 5.5.1 General Due to the complexity of identifying indicators, the process of doing this merits attention. In the context of our project of achieving some form of a stable landscape and food security, indicators may suggest changes in:
• the presence of something; For instance, the presence of seed banks or farmer-led field trials, rill and/or gully erosion (see page 62), the type of soil conservation methods used, the number of trees, might be indicators.
• the type of access to an innovation or new service; The people doing the monitoring might ask: “Are the worse-off taking part, or are the better-off and more powerful dominating the work connected with the intervention?” And record the answers.
• the level of use; For instance we would wish to record on an ongoing basis to what extent (how many times) a crop rotation system, a farming system (see Glossary),
water use management, or minimum soil tillage method is used. This would concern established as well as recommended (by small-scale and subsistence farmers themselves) changes in such systems/methods.
• the extent of an activity; The number of people involved with experimentation, pilot schemes and observation plots would be noted (see Figure 5.3 on page 81).
• the relevance of the change; Does this change (such as a different method of land preparation) assist in resolving our problem (say of declining yield, or ongoing water erosion)? The answer in a case like this would be: “Yes”, it does; or “No”, it does not.
• the quality of the change; The quality, or effectiveness of a change in say land preparation or water management, or in terms of seedbed specifics, the extent to which erosion is prevented, would need to be recorded by say using some system of ranking by numbers.
• the effort required to achieve some change; Say people doing the monitoring would record the amount of manual labour and/or machinery, required for a new (or changed) soil conservation method, such as land preparation based on ploughing along the contour. The aspect of the changes (as per this bulleted list) and the time period over which the changes are being recorded (short, middle and/or long term) determines a range of different indicators to be used. The indicators chosen may well alter over time with changes in environment and relevant adjustment of project objec-

Chapter 5 Researching the Situation to Define Strategies tives and related activities. Also, bringing different people together in such a participatory monitoring process with a view of selecting indicators, brings out their different needs and expectations of the monitoring. The indicator selection work needs to be well conducted to provoke discussion of what participants consider as trustworthy information. Reaching a consensus about objectives and indicators may require negotiation among participants. They will be affected by different experiences, social contexts and needs for information. The choice of indicators will be influenced by differences in gender, age and social status of participants. It follows that the more communities or groups are involved, the wider the variety of identified (agreed) indica-
tors. Hence the need to ‘start small’ (source: Guijt, 1998, pp. 27-28). 5.5.2 The subjectivity of indicators As we are dealing with a ‘problem situation’ (see page 6), negotiated indicators, rather than pre-defined and so-called ‘objective’ indicators, should be used in this process of participatory monitoring. The reason is that participants may look at the project from different standpoints. Monitoring the data will show no more than a partial view of the ‘problem situation’. Therefore an indicator is a means of assisting the communication of complex changes to the wider audience of smallscale or subsistence farmer groups and local (and national) institutions and national government.

In selecting indicators it is therefore important to understand who the endusers of the information are. To quote Guijt, 1998: “Will this indicator enable us to find information that can help us to solve the problems we have identified and
86
to give those we want to communicate with credible and relevant information?” (Guijt, 1998; pp. 28-29). 5.5.3 Type of indicators Indicators might be selected for four different types of impact:
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Indicators 1.
inputs: the resources used in the activity, such as labour, mechanical equipment, land, seeds, planting material;
2.
outputs: the immediate product after using the inputs;
3.
outcomes: the consequences of the outputs afterwards;
4.
impacts: the broader and longer term aims.
time should be devoted to this activity. A so-called objective tree, linking immediate to longer term objectives, and showing indicators for these levels of objectives is shown in Table 5.4 above. In this example we refer to ‘a’ training course. As the intervention under consideration involves for instance crop production techniques and land and water management, a series of different training courses may be required. In our context, this activity refers to ‘training’ the trainers, as deliberated on page 79 and Figure 5.3.
To clarify this, we use (for example) the activity of the training of the first selected group of ten farmers (see page 80), as shown in Figure 5.3 on page 81. Adequate TABLE 5.5. a

To prevent problems arising at a later date, indicators should be as specific as possible and ‘SMART’ (see page 84). In our case the indicators ‘improved’ and ‘increased’ as used in various sections (see for instance ‘Activities’ on page 79)
are not precise. We therefore now set two SMART objectives with respect to a stable landscape and food security, for which definable indicators can be used.
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
87
Chapter 5 Researching the Situation to Define Strategies Objective regarding a stable landscape
6.
Within 3 years the number of locations showing rill erosion in each agricultural field in the area worked with, has been reduced by 50%.
In all cases the indicator can be recorded. Using it, say by farmer groups and/or local agencies, such as extension workers, to increase the use of these practices will tend to create environmental pressures. An example of this is pressure on the state, or local authority to improve infrastructure, indicated by an increasing number of open markets.
This objective is
• specific in its wording; • measurable in that the in-field locations showing rill erosion can be identified;
• attainable. After discussion between all concerned it has been agreed by the small-scale and subsistence farmers that this can be done, for instance (on soils and slopes where this is appropriate) by means of rapid adoption of minimum tillage and soil conservation practices. The latter two practices are inputs, creating output, outcomes and impact (see Table 5.5 above);
• relevant. If water and/or wind erosion are not dealt with, higher yields and increased agricultural production may not be achieved;
• timely. The level of productivity points to the need for action. The indicators state what will be measured: 1. 2. 3.
4. 5.
88
the number of rill erosion spots (still) occurring; the number of gully erosion spots (still) occurring; the area (expressed in number of ha) prepared under the practice of minimum tillage; the number of farmers employing this soil management practice; the number of fields ploughed along the contour;
the number of farmers using these soil conservation practices.
A positive response by these ‘authorities’ to that pressure will be needed, if the intervention is to be successful in the long term (Guijt, 1998, pp. 27-31). This relates to the response of the state to these pressures. A negative and non-participatory response might occur from small-scale or subsistence farmers who have kept on the side line. They may notice an increase in social differentiation, in that some benefit more than others. Agricultural extension workers would have an important task in attempting to alleviate these problems.
Objective regarding agricultural productivity Within 3 years the number of farmers applying the farm and/or cropping system(s) shown in the demonstration plots produced by the participatory farmer-led research, has increased by 50%. This objective is
• specific in its wording; • measurable in that the number of farmers using the evidence of the demonstration plots can be counted;
• attainable. After discussion between all concerned it has been agreed by the small-scale and subsistence farmers that this can be applied by a number of farming systems.

5.6 Methods used to collect and register
Method(s) to monitor indicators regarding water and/or wind erosion The following is indicative only. Different methods could be used, but the example below illustrates that strict discipline is required if this work is to be of use.
The following points are relevant for the process of finding appropriate methods.
• The method(s) used must be appropriate and feasible, in other words it must make it possible to assess, register, compile and analyse or disseminate information.
• The key is simplicity of method, meaning that each method should deal with a limited number of indicators (preferably one indicator only).
• The collection of data, analysis and use of the results should be undertaken by the same people, who should understand the method and agree that it is appropriate.
• To minimize the use of time, and generate the necessary motivation for this collaborative effort, ways should be looked for to incorporate the method(s) into daily work. 5.6.1 To monitor the stability of the landscape As pointed out previously (see Table 5.5 on page 87) we are concerned with the number of spots or locations showing rill and/or gully erosion, as well as with the extent to which soil conservation methods have been, or are being, adopted. These indicators are examples. Other examples could relate for instance to the number of trees found in a given unit area.
FIGURE 5.4. The use of culverts and
gabions in St Kitts. Photo HB.
To observe the occurrence of erosion locations, their number (or frequency) and change in appearance (level of severity), a group of five of the ten farmers walks around the farms, or fields, of each of them, on a transect chosen by the farmer who farms that particular field or farm. The transect represents a structured walk through the area to be monitored with a view to observe the selected indicators. This means that two groups of five farmers each, would be looking at a total of ten transects in accordance with an established and agreed sequence.
• The transect is set out on a map of the field, prepared by the farmer himself.
90
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Methods used to collect and register • The location of the erosion ‘spots’ occurring along the transect are indicated by the group of five farmers on that map and their number or frequency is recorded on a form dedicated to that indicator (frequency) only.
• The severity, in terms of size measured of the rill erosion spots, as well as of the gully erosion spots. This indicator could comprise two different symbols, that is one for the rill erosion (such as a small square) and a different one for the gully erosion ‘spots’ (such as a small triangle). Sizes could be indicated by average length (L) x width (W) in cm and average LxWxD(epth) respectively.
5.6.2 To monitor agricultural productivity As indicated in Table 5.6 (see page 89) we are concerned with the improvement of agricultural productivity leading to increased income for small-scale and subistence farmers and a related increased pressure on infrastructure. The indicators state what will be measured: 1.
the number of the farmers involved with the farmer-led research, who have accepted the results and are now applying these to their farms;
2.
the area of land, measured in ha, applying the cultivation method(s) as per the result(s) from the demonstration plots;
3.
the number of farmers who have observed the (new) technology in the demonstration plots and are now trying this on their own farms;
4.
the number of farmers who have decided to farm according to this ‘new’ technology, having observed the results achieved by themselves and their colleagues;
5.
the yields and production from the crops under observation;
6.
the income, in money terms, derived from these crops;
7.
the response of dealers in agricultural machinery by counting the number of various machines actually purchased and used by the small farmers;
8.
the response of the state and local authorities to the pressure from the small farming and subsistence communities for open markets, by counting the number of markets within (say) 10 km from the centres of a farming community and measuring the distance in km of usable roads needed for
• The times when the transect(s) are monitored are set out on an agreed calendar. This calendar specifies the specific times when the transects are to be inspected, such as the critical times of end of dry season(s) or beginning of rainy season(s) and the end of the rainy season(s) or beginning of dry season(s). After an especially heavy rainstorm a special inspection might be appropriate.
• The sizes of the spots are indicated on fresh maps for each time the transect is followed.
• The number for each of the rill erosion and the gully erosion spots are noted on the form, with separate columns for each date of the monitoring activity.
• To meet the objective stated above (see page 88), the monitoring activity is to be carried out over a period of 3 years.

Chapter 5 Researching the Situation to Define Strategies access to such agricultural commodity markets. These indicators can be recorded. If progress is made, environmental pressures will be created, requiring a positive response from the authorities to bring the infrastructure to the standards needed if farmers are to be able to effectively use their exchange endowments. Social differentiation might create a negative and nonparticipatory response from farmers who considered themselves as being sidelined.
Proposed methods to monitor indicators concerning agricultural productivity An agreed sequence will have to be followed • To determine how many farmers, amongst the initial group of ten who have adopted the results from the demonstration plots, it is necessary for that group of farmers to visit each of their farms at critical intervals to observe their cultivation methods and record the number on an appropriate chart. • The area under these cultivation methods accounted for in ha is recorded on the same chart at the same intervals. • At agreed intervals the ten farmers (‘inspectors’) visit their rural area in accordance with an agreed route indicative for a representative group of a given number of farmers. They determine the number amongst those farmers who have adopted the ‘new’ methods, or a recommended changed farm system. • At the same time the area of land under these ‘new’ methods or changed
92
farm system are recorded by the ‘inspectors’. • On the farms of this pre-selected and representative group of farmers, raingauges are installed and the rainfall is recorded by those farmers on a weekly and if necessary a daily basis. The data are collected by the inspectors when visiting the area for the purpose of their regular inspection indicated above. They are recorded on appropriate rainfall sheets. • At critical times the inspectors visit the representative farms and record production and yields of various crops on appropriate sheets. • During these inspection tours the number of farmers and area of land in ha which in fact have adopted the ‘new’ method(s) is recorded on appropriate sheets. This process is carried out over a period of 3 years. 5.6.3 Control action By the end of the 3-year period results are compared with the aims set by the two objectives specified above (see page 88) and the level to which those aims have been achieved determined. This work is done by the group of inspectors with the participation of the local institutions, represented by agricultural extension workers. The lessons learnt during this monitoring process may indicate that different objectives and different measures of performance are needed. In that case the conceptual model of Figure 3.4 (see page 41) may need to be changed or modified.

FIGURE 6.1. Processes in summary
A process to achieve a stable landscape and food security will be affected by trends or changes in ecosystem processes (see Glossary). This will be looked at in Section 6.2 The human element in the sense of population growth, socio-economic development and good governance has a major impact on the sustainability of development processes needed to promote food security. In this context health and education are important factors also. Trends regarding population pressure will be given attention in Section 6.3. The potential for increasing agricultural production will be considered in Section 6.4. This is done against the background of the ‘problem situation’ as described in Chapter 1. Internal political instability could, potentially, put any achievement of food security beyond reach of any agricultural effort. This will be considered in Section 6.5. The general relationship between these concepts is depicted in Figure 6.1. Apart from the limitations which may be set by state factors (see Glossary), the achievement of a reasonable level of food security may be seen as depending on the ‘hard’ (or manageable) effects of land and soil management and the ‘soft’ (or variable) factors of population growth, agricultural and
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development 93
Chapter 6 Challenges Presented by Natural and Man-made Factors rural development and political stability. These ‘soft’ factors are at the core of the discussion in this chapter.
6.2 Trends of ecosystems The extent to which the performance of ecosystems can be optimized is a crucial factor in the achievement of food security. The properties of ecosystems are of major importance. In our context the management of ecosystems (see Glossary) is directed towards the production of food. The ecosystem functions needed for that purpose, such as the porosity of soils, the depth of the soil profile and the rate of plant growth, must be protected and biological diversity conserved. Action should aim at reducing rates of land conversion (that is deforestation) and improving the planning for (soil and land) conservation. This is regarded as essential because of continuous human development (population pressure), climate and other global changes following on from that, such as unreliable rainfall and global temperature changes. Concepts and principles of ecosystem ecology, important in the context of promoting sustainable management, are discussed below. 6.2.1 Natural and spatial variability The driving forces that determine the structure and functioning of ecosystems, such as variations in climatic, soil and landform characteristics, affect (collective and participatory) decisions regarding for instance the location of demonstration plots (see Figure 5.3 on page 81). Such local and regional factors affect managerial decisions for example with respect to the choice of farming systems to be used in specific areas (see Chapter
9). Past patterns of ecosystem variability are not necessarily a good indicator on which to base predictions of future change. For instance climate change may result in temperature and rainfall patterns which differ from the past. Water running downhill will affect a soil profile in the upper regions differently to those in the lower (downhill) regions. Consulting and involving the local farming community can be of considerable value in this regard. 6.2.2 Resilience and resistance The aspects of resilience and stability of ecosystems are important perhaps especially in view of human-induced change. When considering this from a landscape perspective a series of such changes could occur, simultaneously or in a sequence of some kind. This means that ecosystem properties might undergo some change, for instance as a consequence of soil conservation techniques. Such techniques will aim at strengthening properties such as soil organic matter or microbial community. Ecosystem resilience (see Glossary) may help to maximize the beneficial effects of such actions, whereas its resistance to change may make it more difficult for actions to produce a positive effect. 6.2.3 State factors and interactive controls To manage agricultural crop production in some sustainable manner it will be necessary to observe state factors and their interactive controls (see Glossary). State factors are largely beyond the control of those promoting food security, but interactive controls can be important tools. Interactive controls (see Glossary) which can be managed are resources, such as irrigation and fertilizers, times of soil and land management and crop produc-

An important example of interactive positive feedback is the exchange of carbohydrates provided by plant roots to mycorrhizal fungi in return for plant nutrients. This is seen as an exchange of growth limiting factors promoting the growth of both the plant roots and the fungi (Chapin III et al., 2002, p. 13).
The increase in total populations and that for the rural and agricultural sectors has been shown in Table 2.1 (see page 23). In this section the subject will be discussed by looking at demographic characteristics and socio-economic consequences with regard to small-scale and subsistence farmer family households.
6.3 Trends of population growth and density
Table 6.1 (see page 95) indicates that in the year 2000 some 80% of the world population lived in developing countries. By the year 2050 the projected world population may be as much as 9.3 billion people, of which some 87% would be in developing countries. This is expected to increase.
Population pressure is an important factor affecting development. Population pressure and poverty affect the sustainability of the natural resource base and in that regard, land. The manner in which that land is used is of primary importance.
Table 6.2 (see page 96) shows that the total world population has increased by some 74% from 3.7 billion to 6.5 billion over the 35 year period from 1970 to

Chapter 6 Challenges Presented by Natural and Man-made Factors 2005. On the continent of Africa the population increased virtually 2.5 times over that period. The massive population in Asia increased by 80% plus during that same period. This is a trend which set in during the 20th century and continued especially during the second half of the 20th century. These increases emphasize the need for food security. In our context especially the increases in Africa and Asia are important. Historical and predicted populations Figure 6.2 (page 97) shows that the population growth of Europe and Northern America are declining, but the steepest increases continue in Africa and Asia, with an acceleration of growth after 1950. A useful analysis can be found in Szirmai, 2005 (see Bibliography). As long as the industrial capacity of most developing countries (here especially in AFR) remains low, one would not expect a shortage of agricultural workers in rural areas to be a potential problem. As development proceeds, the demand for industrial workers will increase. The requirement for competent and efficient workers in the field of food production highlights the need for productive agricultural practices. so that labour productivity and rewards for those workers become sufficiently attractive when seen in the light of (future) industrial productivity and rewards. Population pressure in poor countries with a low level of industrialization results in a requirement for more agricultural land, which can put pressure on deforestation in order to produce that arable land. The need for fuel wood and logging can lead to deforestation, contributing to increased CO2 emissions
and declining biodiversity. Also forest clearing in areas of high altitude can lead to land erosion and downstream flooding. To keep this in hand, soil and land management is essential. On a global scale, such clearing of land for agricultural purposes has resulted in a reduction in regional albedo (see Glossary) and evapotranspiration. This leads to a greater sensible heat flux (Chase et al., 2000), involving the atmospheric transfer of heat and water vapour between ecosystems, thereby affecting ecosystem processes in down-wind ecosystems (Chapin III et al., 2002, p. 320). From a global point of view therefore it is important that in advanced countries forest coverage is increasing, which, to some extent may be a result of a declining demand for crop lands in those areas. 6.3.2 Population densities Appendices 1 and 2 (pages 218 and 219) indicate the population densities and the PPP$ income per capita by the year 2003 for the countries in the WDRs of AFR and SAS respectively. Some main data are summarized in Table 6.3 (page 99). The population density, as well as the PPP$ income per capita in SAS are significantly higher than in AFR. The variation between countries, especially in AFR is considerable. The general position in SAS is more balanced than in AFR. In SAS there is a higher per capita PPP$ income as well as a much higher population density, leading to more favourable conditions for infrastructure development. However, this aspect of infrastructure remains pressing in these areas. If small-scale and subsistence farmers are to have the opportunity to promote small-scale agricultural development

Government agencies, such as agricultural extension services will have to function efficiently. This is essential if hunger and poverty in these areas are to be reduced to a level within the boundaries of human dignity.
The human impact on the environment The debate on this is lively and important. It falls outside the scope of this volume (and the competence of the author) to contribute to it. However, following Szirmai, 2005, it appears that “there are ever stronger indications that the growth of world population and the associated growth of world production are beginning to form a threat to the environment at a global level with consequences which may be irreversible” (Szirmai, 2005, p. 161). As this is important for the achievement of stable landscapes and food security, and
again following Szirmai, 2005, the following indicators merit comment.
Deforestation. The expansion of the cultivated area of land (one important factor for the increase of food production) reduces the amount of land available for pasture, housing, roads and urbanization and particularly that available for forest and woodland. In the context of the value of forests (including various types of woodland) as a carbon sink, during the decade from 19902000 as much as 5.3 million ha of forests were lost each year in the WDR of AFR, amounting to 0.76% as compared to worldwide 0.24%. For SAS this came to 98 thousand ha/yr or 0.12%. Particularly rapid deforestation occurs in Niger, Nigeria, Rwanda, Sierra Leone, Sudan, Togo, Uganda, Zambia, Zimbabwe in AFR and in Nepal, Pakistan and Sri Lanka in SAS (see Appendix 3, page 219). A reduction of the regional albedo and the increased heat flux are important con-

Intensify land use by: shortening the period of fallowing multicropping (more than one crop per year from the same piece of land)
3
Increase yield (the return per harvest per ha). This may be achieved by intercropping - the practice of growing two or more crops at the same time in the same field increased mechanization when labour is scarce land substitution investments, such as investment in irrigation, organic and chemical fertilizers, development of high productivity seeds. Such investments tend to be land saving and labour intensive
The presence of tropical forest, due to its beneficial effect on overall soil conditions would promote a stable landscape regarded essential for the achievement of yield improvement and sustained agricultural production. This is discussed below.
6.4 Trends of agricultural production and food security1 Agricultural and rural development is necessary if sufficient agricultural production is to be sustained in the face of increasing populations.
1. This section is based on Chapter 10 ‘Agricultural development and rural development’ of A. Szirmai, 2005, The Dynamics of Socia-Economic Development, Cambridge University Press, pp. 354-425.
Agricultural production can be increased in three different ways (van der Meer, 1983), summarized in Table 6.4. 6.4.1 Expand the cultivated area Land use in the WDRs of AFR and SAS has been discussed in Chapter 2 (see Table 2.4 on page 28 and Figure 2.4 on page 29). From Table 2.4 it is apparent that the amount of pasture land in AFR (53% of the land areas in year 2002) is relatively substantial. Such pasture land could (to an extent) be used for agricultural crops and secondly potentially for the planting of crops for bio-fuels, such as oil palm and appropriate types of grasses. This will need regulation by governments, prohibiting the use of any forest or arable land for the purpose of producing crops for biofuels (see Chapter 7).
100 Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Trends of agricultural production and food security From Table 2.4 it is also apparent that this potential possibility of expanding the cultivated area is not available in SAS, there being just some 10% of the total land area in pasture in 2002. 6.4.2 The intensity of land use
Shortening the period of fallowing Some 200-300 million people practise slash-and-burn agriculture on around 30% of exploitable soils worldwide. This important practice is fallow-based (Crutzen and Andrea, 1990). Slash-and-burn agriculture is a good practice in areas where there is relatively abundant land and low population density, allowing for long fallow periods (Kleinman et al., 1995). However, increasing population densities lead to shorter fallow periods and the cutting down of primary forest. These factors tend to promote a decline in agricultural productivity (Thiele, 1993). Therefore in the long term a slash-andburn practice potentially is counter-productive from a food security point of view. Encouraging the natural regeneration of plant species that assist the land to recover quickly, such as leguminous nitrogen fixers, and by actively planting those species, small-scale farmers would manage their fallow better. However, in the short term farmers need to consider the costs and benefits of changing their current method of fallowing to this ‘improved fallowing’.
Total land use. A main factor is the need for land. Less land for crop production would be needed under the conditions given below:
• the less time land must be left in fallow to achieve restoration of soil fertility, the earlier the farmer can return to that land to cultivate food crops;
• the longer a farmer can cultivate an area before passing on to another area, the more time the fallow area has to recover its fertility. Agronomic research is needed in AFR to compare the costs and benefits between types of fallow. Following Angelsen and Kaimowitz (2001, p. 212) one might distinguish the following types: 1.
high secondary forest fallow; land under vegetation higher than say 5 m, which is to be cleared;
2.
low secondary forest fallow; land under vegetation to be cleared which is less than 5 m high;
the so-called improved fallowing (see above). A comparative analysis of the following variables for each of the types of fallow could throw some light on the issue: 3.
• average years of fallow; • average years of cultivation; • total land clearing. One has to consider the crop system used in the farm system (see Chapter 9). An annual crop in that system might need say 0.5 ha in subsistence farming;
• comparative land use. The land use (ha) under the ‘improved fallowing’ should be the base comparison at 100%. The result of such analysis might indicate the percentage of the amount of less land needed by farmers who use the improved fallow method as compared to those who use the low and high secondary forest clearing methods. This is based on 0.5 ha of annual crops. The results would differ under perennial crops or with a different area under cultivation. Those other circumstances should undergo a similar type of analysis. As this could indicate the

Chapter 6 Challenges Presented by Natural and Man-made Factors instance leguminous nitrogen fixers, such as kudzu (Pueraria lobata), may reduce the amount of trees and shrubs in the fallow, reducing the need for labour, which can be beneficial in view of the pressure on time (which may be needed for carrying water) in subsistence farmer households (Table 6.5).
potential for a reduction and intensification of land use, this is important to be followed up.
Labour use. Generally
speaking the clearing of primary forest as well as high and low secondary forest fallow types require more labour than an improved fallow type does. The latter, when using, for TABLE 6.5.

The kudzu plant is an aggressive cover crop requiring relatively little labour as it tends to smother herbaceous weeds which invade fallow area. Some wetting of the soil and minimal cultivation is needed to plant kudzu. It is advisable to use 1 cm thick cuttings from kudzu young stalks, cut just below the oldest node. TABLE 6.6.
The cutting should contain some 2 to 3 nodes and after drying for 24 hours planted at some 3 m intervals. The plant may cover the soil within one year without further need to cultivate the soil (Angelsen and Kaimowitz, 2001, pp. 218, 219).

102 Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Trends of agricultural production and food security bling it to continue producing new shoots and ground cover. After some 11 months such roots may be 7 cm thick at a length of 70 cm. They are edible after having been boiled. The green leaves of this plant can be used as feed for cattle (Heyne, 1950). Although it may be argued that this needs labour, the advantages of growing this cover crop on fallow land are considerable in that the growth of herbaceous weeds is suppressed. When bringing this improved fallow back under cultivation the area requires less weeding than those from other forest fallows (Table 6.7). Forest clearing and weeding are critical labour requirements limiting production (Thiele, 1993). Improved fallow could reduce the labour requirements as compared to high and low secondary forest fallow. As a result the farmer would have more time and could put more land into cultivation. As in AFR just some 13% of agricultural land was used for arable and permanent crops (see Appendix 4, TABLE 6.7.
page 222) as opposed to some 81% in SAS (see Appendix 5, page 224), the small-scale or subsistence farmer in AFR may have the land resource to do this. In SAS an increase in deforestation might be the result of the farmer looking for more land, having more time due to needing less time for weeding activities.
Yields. Although forest burning produces a nutrient flush, with high secondary forest generally providing the best biomass burn, kudzu fallow fixes nitrogen and makes other nutrients available that accelerate soil fertility recovery. Moreover, kudzu effectively reduces weed competition. Weeds, if not controlled sufficiently, can have a disastrous effect on crop plant growth. These two factors of nitrogen fixation and weed control combine to produce an increase in yield after kudzu fallow, as compared to primary as well as secondary forest fallows [see Table 6.7 (Angelsen and Kaimowitz, 2001, p. 219)].

Kudzu fallows and deforestation. Continuing to follow Angelsen and Kaimowitz, 2001, who discuss the technology of kudzu-improved fallow in the lowland Amazon surrounding Pucalpa, Peru (see their pages 214-227), the technology reduces fallow periods and labour
costs and increases yields. They point out that this leads to two different hypotheses: 1.
due to shorter fallows, the total amount of land needed in a slash-and-burn agricultural system is reduced, leading to reduced deforestation;
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development 103
Chapter 6 Challenges Presented by Natural and Man-made Factors 2.
the relieving of labour constraints by the kudzu-improved fallow system in a slash-and-burn agricultural system, increases deforestation as farmers now have more time to put land under cultivation.
These hypotheses contradict each other with respect to their effect on deforestation. However, it appears likely that 3.
changes in the relative cost and benefits of secondary versus primary forest clearing due to kudzu fallows, may well reduce the amount of primary forest cleared, whilst increasing clearing of secondary forest (Angelsen and Kaimowitz. 2001, p. 220).
The implications for AFR and SAS The above looks at agricultural aspects only. But, as pointed out by Angelsen and Kaimowitz, 2001, p. 224, quite apart from land and its fertility, the farmer depends on labour and capital. Sandy soils, labour constraints and lack of credit tend to promote the technique of kudzu-improved fallow. Infrastructure, the availability of and distance (transport) to markets play an important role. Education plays a role too in that more educated farmers may adopt the kudzu-improved fallow technique, because the saving of time (less weeding and so on) may offer the opportunity to maximize their exchange entitlement by looking for paid work off-farm.
• AFR The kudzu-improved fallow technique could be beneficial in AFR in that land availability is less of a limiting factor than in SAS (see Appendices 4 and 5). Due to relatively longer fallow periods, farmers might have more time to convert pasture land into agricultural land without further deforestation. Also the frequently shallow
and sandy soils occurring in this WDR might stimulate the technique. Also, as in the Amazon lowland (Angelsen and Kaimowitz, 2001, p. 224) good examples might promote it spreading among farmers, without extension services being involved. As the technique does not demand capital, a lack of credit might not be a hindrance. Any such increase of productive farmland, without any significant deforestation, could begin to combat poverty and hunger so prevalent in the region. Seen from an optimistic point of view, the relative ease with which grasses such as Rotboellia exaltata, Cynodon dactylon and Panicum maximum can be grown on these sunny lands, the technology (at the time of writing, in 2009, under research) of converting cellulose from these plants into bioethanol, holds some promise as a source of income for these small-scale and subsistence farmers.
• SAS In SAS, on the other hand, population pressure and land availability for agriculture (see Appendix 5, page 224), may lead to more deforestation. Kudzu-improved fallow could promote a reduction in the clearing of primary forest. Accessible markets would play an important role. An improving level of education in this densely populated region and infrastructure might help to promote kudzu-improved fallow. In general, the advantages and disadvantages of the kudzu-improved fallow method appear to be well worth examining. Applied research regarding the method of fallow should be located in
104 Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Trends of agricultural production and food security areas where the availability of markets and roads are not limiting factors. Once advantages of a specified fallow method has been demonstrated, they could serve as a driving factor for the reduction of primary forest deforestation and improvement of infrastructure. Full participation of the farming community will be needed regarding the series of variables affecting improved fallow results. Examples of these variables are farm size, soil type, years of farming the specific lot, education, family labour, off-farm income, distance to social services, availability of credit, distance to markets, other deforestation fallow methods (see Angelsen and Kaimowitz, 2001, pp. 220-224).
Cropping intensity
or total arable land area in use. A cropping intensity of 1 indicates that a cultivated area is harvested once per year. There is a significant difference in cropping intensity between irrigated and non-irrigated land (see Table 6.8). With the exception of South Asia and East Asia and the Pacific, amongst which India and China stand out, the cropping intensity hitherto is low. However, it has increased over the years, pointing to a reduction in fallow periods and associated pressure on the maintenance of soil fertility. However, land use is still relatively low, especially in AFR (see Table 2.4 on page 28), which might alleviate this potential problem. The figures for 2030 are indicative of a potential increase in cropping intensity, which however may remain marginal in AFR.
This can be defined as the ratio of total cropped area x 100 / total cultivated area TABLE 6.8.

Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development 105
Chapter 6 Challenges Presented by Natural and Man-made Factors As for future availability of food in the context of the growing world population, one should consider increasing crop intensities against the background of land use in specific areas (Bruinsma, 2003, p. 135). 6.4.3 The increase of yield
Intercropping Introduction. The practice of growing two or more crops at the same time has been followed by local small-scale and subsistence farmers since ages gone by. They managed to maintain soil fertility without the use of non-renewable resources This should be seen as a major cultural achievement by so-called Third World peoples. Research, quoted by Innis (1997) shows that intercropping, apart from financial benefits, offers agronomic and ecological advantages over monocropping (Innis, 1997, p. ix).
The nature of intercropping.
The growing of more than one crop at the same time on the same plot of land has been found by indigenous people to maximize yield and maintain soil fertility. The main grain and legume crops, derived from local plants and adapted to local environments, usable for the purpose of intercropping, are maize and beans in the Americas, millet and cowpeas in Africa, wheat and chickpeas in the Middle East, sorghum and amongst other vegetables, pigeon peas in India, rice and soybeans in China and oats, peas, beans and barley in Europe (Innis, 1997, p. 1). The system of intercropping is concerned with small-scale and subsistence farmers fitting crop plants, suitable for a given environment, into intercropping combinations. By doing this effectively
these small farmers have been able to keep soil fertility at usable levels.
Ecological advantages of intercropping. Innis (1997, p. 2) compares the use of intercropping to selective cutting of trees in woodland. If managed correctly, several kinds of trees will grow in a natural forest in a temperate climate in a given area of that forest. As under these conditions debris and other detritus material collects on the surface faster than it is removed by decomposition, leaching and surface erosion, soil tends to build up. This is because most of the sunlight will be intercepted by several layers of leaves, whilst at the same time the soil profile is better explored by plant roots at different depths. In contrast to this aspect of growing different crops (trees) at the same time, monocrop (the same type of trees), will tend to produce leaves at the same level, intercepting less solar energy and thus producing less organic matter. Furthermore, with a monocrop, sunlight not intercepted by leaves will hit the ground surface causing more evaporation than is the case in an intercropping system where the soil surface remains protected by a layer of protective detritus (dead organic matter). In a monocropping system, due to a comparative lack of detritus on the soil surface, less water will be held by that material on the ground and by the pore spaces of a soil with adequate organic matter content, as tends to be promoted by an intercropping system. This is because considerable vegetation remains after a partial harvest in an intercropping system. In traditional agriculture intercropping is common and sophisticated within traditional cultures. Experimental work at agricultural stations in the developing world recognizes this and endeavours to meas-
106 Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Trends of agricultural production and food security ure the efficiency of intercropping farming practices in utilizing resources. Experiments have shown that intercropping produces greater growth than monocropping with given amounts of water and light and where all other factors are the same (Innis, 1997, p. 3). As we are concerned with valuable traditional farming methods, such experimentation should involve the traditional farming community. Participatory, farmerled research might be the approach to carry this forward at a greater (urgent) speed.
Effect of intercropping on yield. To show this effect, controlled participatory farmer-led research should be carried out. To underpin the advice (and wishes) of small-scale farmers to match crops to inherent fertility and physical characteristics of each soil unit, the FAO-UNESCO legend of the soil map of the world could be of assistance. Useful examples of showing the greater effect on yield by intercropping over monocropping have been given by Innis, 1997, pp. 3-33. To give context to methods of intercropping, Innis, 1997, p. 3 gives the example of comparing three equally sized plots, the first with a monocrop of beans, the second with a monocrop of maize and the third with intercropped maize and beans. The fast growing young bean plants provide a soil cover and use solar energy earlier than the maize plants. The different growth habits of these two plants come to the fore in the intercropped plot. The rather vertical leaves of the maize plant trap only part of the sunlight whilst the remaining part of the solar energy largely is absorbed by the horizontal leaves of the beans. When comparing yields, the yield of the individual crops, harvested from the monocrop plots,
are higher than the yield from the same crops in the intercropped plot. Also, when harvesting a monocrop from a bigger plot than normally would be the case from an experimental plot, monocrops might be suitable to be harvested mechanically, such as might be practised on commercial farms. However, from a food security point of view, one should consider conventional small-scale farming, such as carried out by middle income small-scale farmers involved in simple commodity production (see Chapter 2 and Figure 2.2 on page 21). Such family households would be able to pick a few beans almost daily for weeks as individual pods become sufficiently large for consumption. This stands in sharp contrast to mechanical harvesting of green beans, which tends to damage plants to the extent that no more can be harvested from the same stock. In small-scale farming plots, beans, grown as monocrops would be harvested manually in a manner similar to that employed for intercropping, producing a higher yield than that for the individual crop in the intercropped plot. The same would be the case when harvesting and counting the number of maize cobs yielded. Importantly however, the total harvest, per unit area, obtained in total from the two crops in the intercropped field or plot is likely to be higher than that of monocropped yields. A means of putting these comparisons on a sound basis has been developed as the land equivalent ratio (LER) by the International Rice Research Institute (IRRI) of the Philippines. With respect to the example given, Innis, 1997, p. 4 reports that the intercropped beans produced 0.69% of the yield of the monocrop beans and the intercropped maize produced 0.66% of the

Chapter 6 Challenges Presented by Natural and Man-made Factors monocrop maize. The total LER came to 1.35. One sees therefore that under the same resources of sunlight, water, nutrients and space, the two intercropped crops produce 35% more than when each was monocropped. Appendix 1 of Innis, 1997, lists hundreds of LERs obtained from many countries, showing that intercropping is not an untested method of producing crops. Interestingly, although most of the experiments cited in that appendix compare the yields of monocrops and intercrops of two crops, Innes reports that when the yields of three or four intercropped mixtures are measured, following the traditional harvesting methods, the yields from the same resources can indicate LERs some three times that from monocropping The promotion of intercropping methods, by creating infrastructure and accessible markets for produce on a scale accessible to small-scale and subsistence farmers (largely achieved in Taiwan) could go some way to alleviate world hunger (Innis, 1997, p. 4). This shows that it would be beneficial to concentrate applied farmer-led participatory research work, such as described by Figure 5.3 (see page 81) on intercropping practices on small-scale plots, versus those of monocropping on such plots. For this reason, factors involved in intercropping will be described below, again following Innis, 1997.
Factors involved in intercropping. • Growth of biomass For a pot experiment in Wales, with 36 plants per pot, the above-ground parts of the plants were weighed at 4, 8 and 16 weeks after planting. The plants used were barley, mustard and poppy. When the 36 plants were of the same species, the biomass weight was less
than when 18 plants each of two species were grown and more so when 12 plants each of the same species were harvested. This showed that different leaf and root systems grown in conjunction in the same space can absorb more solar energy and more water and nutrients than if one grew one species only. In the latter case the roots have to compete with each other, being similar in their orientation and below-surface depth. The leaves of plants of the same species are opposite each other and grow at the same rate. Roots and leaves of different species do not compete in that direct manner with each other for water, nutrients and sunlight (Innis, 1997, p. 5). It is worthwhile including something along these lines in the experimental work considered in Figure 5.3 (see page 81). It can show interested parties in some direct manner the potential benefit of intercropping as compared to monocropping.
• Spacing In Illinois an experiment with oats and soybeans planted in alternate rows with different spacing between them showed that in studies regarding intercropping actual yields by weight from the crops should be recorded and not just the LER. The reason is that optimum LER may disguise the fact that optimum yield of one crop, such as soybeans at a spacing of 81 cm and oats at 81 cm, may be achieved at the expense of the other crop. The spacing for soybeans may be optimal at 81 cm, but oats can give better yields per ha at a closer spacing, such as 21 cm. This complicates the issue to an extent. This is the case especially when intercrop-

Trends of agricultural production and food security ping trials use varieties, say from maize and soybeans, bred for highest yields as monocrops. A crop such as hybrid maize has become so productive that a reduction in the number of maize plants, or for that matter a reduction in maize yield through competition with another crop, may be difficult to compensate for by extra yield

from a second or third crop. This shows that in trials on intercropping at a given area, the same area must be grown under monocrops at the same time. The monocrops should always be planted at their optimum spacing. The intercrop trials should compare a number of different spacings and keep in mind which crop is

Chapter 6 Challenges Presented by Natural and Man-made Factors the most important for the production of food at the time when the experiments are conducted.
• Nitrogen A difficulty may arise out of the fact that legumes, which can fix atmospheric nitrogen and make it available to other plants, tend to stop doing this when mineral nitrogen fertilizer has been added. Nevertheless, as the total weight of grain, in intercropping with maize and soybeans, tends to be much higher when nitrogen is added, it is worthwhile adding the nutrient, accepting the competition for the mineral nitrogen by the soybeans, thus reducing the benefits of intercropping. The high cost of mineral nitrogen has reduced the economic optimum of using this fertilizer. In cases where this use is too expensive, or where the material is not available, as may be the case in isolated rural areas, intercropping continues to be cost effective. Innis, 1997, p. 8 gives, amongst others, an example for Sri Lanka. Here, intercropping was 51% more profitable than monocropping when 25 kg/ha of N was added, but when no N was added the net yield was 81% more for intercropping than for monocropping (Gunasena, 1980). As pointed out above the height and manner in which leaves grow between plants competing for light is important in intercropping. It therefore seems that the development of cultivated varieties, especially suitable for intercropping, is important.
• Water As mentioned above, plants growing in an intercropping system can absorb more water than a plant under a
monocrop. The reason is a higher interception of sunlight, whilst at the same time different root system growing alongside each other may explore the soil moisture reservoir at different depths. In dry areas ‘modern’ farmers tend to rely on taking water from groundwater supplies by means of costly pumping. Instead of potentially lowering the watertable and making it more inaccessible to many people, one should ensure that the soil water reservoir is fully explored. In this regard, a system of using intercrops may be more cost effective than monocrops (Innis, 1997, pp. 8-10).
• Light Depending on latitude it is important to grow plants together which use the optimum amount of solar energy during the period of the growing season. This can be achieved if one is aware of the leaf area index (LAI, see Glossary) of each of the (two) crops to be grown together. Innis, 1997, p. 11 gives an example where, in North Carolina, maize uses sunlight mainly during the early part of the growing season, whilst the late-season sunlight tends to be wasted. On the other hand, soybeans, being small and slow growing at first, uses the maximum amount of sunlight in the late part of the growing season. This is shown by the development of the LAI of the two crops and hence the amount of energy used by them (Figure 6.3, page 109). In this experimental example the LER for the combined yield by weight for the two monocrops is taken at 1.00. When grown in an intercropping system, the soybeans have a smaller leaf area at a comparative time, than when grown as a monocrop. However, once
110 Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Trends of agricultural production and food security maize has been harvested (at day 250), and the beans are in the pod-forming stage, the total yield is encouraging, an LER of 1.73, or an increase of 73% in yield by weight for the same resources having been calculated (Cordero and McCollum, 1979). This shows that the increased use of light by plants growing under a system of intercropping can be advantageous. Provided the lower leaves are adapted to lower light conditions, multi-storey plants harvested in sequence can make use of the sunlight’s energy on a year-round basis (Sebastiani, 1981, Osiru and Kibira, 1979). Innis, 1997, pp. 11-13 presents a number of examples of this important aspect. Innes points out also (1997, p.13) that apart from growing multi-storey plants, the technique of growing plants that develop at different rates is useful. The example illustrated in Figure 6.3 shows this. He gives a number of further examples on his pp. 13-14.
• Time The above is further emphasized by Innis, 1997, pp. 15-17, highlighting the potential benefit of bringing shortand long-term plants together in a field. This highlights the technique of planting three crops together at different times and harvesting them at different times. Examples of this can be found in Nigeria, where millet, cowpeas and sorghum are planted together. The 80-day millet may grow to a height of 1.5 m by which time it is harvested, leaving more resources for the slow growing sorghum, which takes some 168 days to reach maturity. Cowpeas are worked into this traditional system of intercropping (that is millet and sorghum planted at the same
time, but harvested on a different time schedule) by planting them, after the millet has been harvested, in the spaces left by the millet. This so-called relay cropping gives the small cowpea plants the opportunity to utilize nutrients and water still available alongside the developing stand of sorghum. A most important aspect of this form of relay cropping is the long-term protection against soil erosion, practised successfully by Nigerian farmers, rather in contrast to ‘modern’ agricultural methods (Andrews, 1972). Relay planting is widely used for instance in Indonesia, thereby maximizing demands on resources at different times during the growing season. An example is the planting of cassava in the same fields where rice and maize are intercropped. To prevent the cassava competing with the two grain crops at an undue time, it is planted some 30 to 40 days after the planting of the rice and maize (relay planting); thus harvest dates are spread, maize being harvested after 80 days, rice at 140 days and cassava after about a year (Effendi, n.d.). The above shows that under conditions where a household is involved in agriculture, such as occurs in many parts of low income countries, forms of interplanting crops by hand can lead to considerable benefits, both financially and in terms of (food) production by weight. When it comes to working out how to proceed with farmer-led participatory research and experimentation, and working out the factors to be included in the model for the combined approach, a thorough understanding of traditional forms of intercropping and relay planting is a prerequisite. The small-scale and subsistence
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development 111
Chapter 6 Challenges Presented by Natural and Man-made Factors farmers in regions where these agricultural systems are practised should be consulted and involved with the design of experiments. Improving agricultural performance in this way, that is by the small-scale farmer exploiting his knowledge and understanding of local circumstance, is not expensive and might be fully supported by the rural community as it could lead to increased food security through increased land equivalent ratios (see ‘Effects of intercropping on yield’on page 107).
• Nutrients Innis, 1997, pp. 17-21, contemplates the advantage of intercropping in conserving nutrients. In that context Agboola and Fayemi (1971) are referred to. The results of their work are summarized as follows. 1.
When maize (a tall plant) is planted in rows adjacent to a short legume crop, here greengram, the competition for light with other tall maize plants is reduced. The short legume plant next door mobilizes sufficient nutrients for a high LER of 2.08 being achieved, without addition of any mineral fertilizer. When maize is the only crop, or when maize is intercropped with cowpea and with greengram, the nutrient loss was highest when maize was produced as a monocrop. The reduced nitrogen loss with intercropping with legumes is attributed to the presence of the legumes, mobilizing the nitrogen. The reduced losses of P and K may be due to root systems being present at different depths, preventing leaching and erosion. This may be due to the detritus of dying legume plants having been deposited on the soil surface. The
aspect of root systems at different depths is an important potential benefit of intercropping as compared to monocrops. 2.
When mineral nutrients have been added intercropping can also be useful. Maize production in the fertilized intercropped plot was higher than that of the unfertilized maize. This is attributed to the greengram providing little competition to the quickly and tall-growing maize, depriving the greengram from essential solar energy. However the non-development of the greengram resulted in a lower LER, here 1.42 as compared to 2.08. The higher LER stated Example 1 was due to the greengram having been able to develop in the company of the lower non-fertilized maize. Cowpea and greengram do not fix atmospheric nitrogen when mineral nitrogen is added to the soil. These legumes, under the conditions of artificial fertilizer having been added, removed twice as much nitrogen from the soil as maize alone (no legumes).
The conclusion is that intercropping in circulating nutrients has a beneficial effect. The roots lower down in the horizon collect soluble nutrients leached from the upper part of the soil profile, which have not been collected by shallow-rooting crops, or, for that matter, the soil matrix. Two crops grown together tend to leave the soil in better condition in the long term than a system producing a monocrop (Agboola and Fayemi, 1971). This is a point of significant importance to consider when, together with local and traditional farmers, designing the approach to farmer-led research (see Figure 5.3 on page 81). In the face of the ever-more pressing need for food security,
112 Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Trends of agricultural production and food security the maintenance of soil fertility in the long term is of major importance. The contribution already made to this over centuries by traditional small-scale farming should be recognized. When endeavouring to increase yield by adding fertilizers, crops grown in intercropping systems should be such that leaf canopies as well as root systems of the crops concerned can compete for the available resources at the appropriate time during the growing season.
• Labour Under conditions where some family members of a ‘middle-income smallscale farmer household’ (see Figure 2.2 on page 21) have no other employment, it can be beneficial for the family to grow a third, or even a fourth intercrop. Family labour would be working their endowment, using their direct entitlement, that is they own the food produced. The principle is that the family will be interested in maximizing production rather than profit. To achieve this, the family members would devote their time and effort to three or even four appropriate crops grown on the same piece of land at the same time. Provided the correct balance of crops and timing is used, the use of available solar energy and moisture would be maximized. Innis, 1997, p. 23 states that this can be achieved for example by intercropping maize and beans (T. Anderson, 1976; Hasselbach and Ndegwa, 1980) and cassava in intercropped mixtures (Porto et al., 1979). The spreading of the work involved over the time available, maximizes the effect of using the direct entitlement (see page 20).
This stands in contrast to the ‘rich small-scale farmer household’ (see page 20), which, being commercially oriented, will tend to work towards maximizing profit. Such households tend to grow only the most profitable cash crop for sale, as quantity and transport are main factors to consider. Small quantities of secondary and tertiary food crops generally would be too expensive to produce. The ‘rich small-scale farmer household’ therefore is involved in petty commodity production by mobilizing its trade entitlement, contrasting with the ‘direct entitlement’ of the ‘middleincome small-scale farmer household’, involved in ‘simple reproduction’. The availability of labour in the form of household members is a major asset for the middle income small-scale farmer household. Depending on circumstance these members may be working for lodging and board. Some cash may come available as the crops develop. Although it may be argued that the effective wage per hour of such labour is very low, it guarantees constant employment on the family farm, in contrast to the rich small-scale farmer household or (small) commercial farmer. The latter will use labour only as and when needed and simply not grow a second intercrop if the cost of doing so is higher than the commercial value of that crop. Another point is energy. When considering the two contrasting households from the point of view of energy balance, the ‘middle’ household is more effective than the ‘rich’ household. The former will work with manual labour as much as possible and use animal traction where needed. The latter, being commercial, may use tractors to plough the land on time.

Innis, 1997, p. 23 calls attention to the fact that a buffalo may expend some 800 calories per hour of work, while a tractor expends some 90,000 calories per hour. A tractor may take two hours to complete the same amount of work a pair of buffalos does in two eight-hour days, however using seven times as much energy (Ter-
hune, 1976). There is a relationship between the size of the farm to be worked and the need to get the crop in the ground on time. The bigger the farm the higher the need for motive power. However with rising fuel prices, fewer farmers will be able to afford tractors using a non-renewable resource. The availability of manual
114 Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Trends of agricultural production and food security labour plays an important role in this (Innis, 1997, p. 23).
• Insects Innis, 1997, pp. 23-28 presents a number of examples showing a reduction of insects as a result of intercropping. This was particularly the case with crop combinations producing the most shade (Moreno, n.d.). As some insects attack more than one crop, some intercropping combinations (if such insects affect all crops), do not reduce the number of insects (Wiley, 1979a). Innis gives the example of Pyrilla increasing in number when the grains jowar and bajri were grown together, but coming down in number when jowar was intercropped with the legumes pigeon pea or blackgram (De and Singh, 1979). Insecticides, which tend to kill nearly all insects, disable biological control. This can give rise to problems caused by some insects immune to the insecticide. Innis, 1997 (p. 24) quotes the example of the immune fruit-tree red spider (Dempster and Coaker, 1972). This highlights the importance of natural (or biological) pest control and of intercropping of appropriate crops. The importance of the careful selection of crops to be used in intercropping is apparent. With the appropriate selection of plants and the use of (when opportune the introduction, or use of appropriate insects) natural pest control, the effects of pests can be minimized.
• Disease As insects may spread disease, pest control generally will depress the occurrence of plant disease. The control of diseases can be promoted further by intercropping as shown by the
result of an experiment in Tanzania, demonstrated by Figure 6.4 (see page 114). This effect might be explained by the circumstance that in monocrops leaves of the same plants of the same age touch each other, thus providing a pathway for the disease to spread across the field, whilst with intercrops this is not the case. The shorter crop, planted in rows adjacent to the longer crop, could be seen as providing a barrier to this effect (Innis, 1997, p. 29). When traditional farmers, working with intercrops, select seeds, which have survived and therefore have not been affected by disease, for next year’s planting, they select for disease resistance (Innis, 1997, p. 31). Once again this shows the benefit of intercropping as practised by traditional small farmers. The aspect of the occurrence of diseases in intercrops should be seen as an important factor when working out experimental procedures in the farmer-led participatory applied research referred to in Chapter 5.
• Weeds Weeds tend to be less of a problem in intercropping systems than in monocrops. In the former, the second (and sometimes third) crop tend to provide ground cover at a relatively early stage, suppressing weed growth (Waddell, 1972). Herbicides in monocrops can be effective, but remain expensive and subject the open spaces between rows to erosion. Innis, 1997, p. 32 reports that at ICRISAT (see List of Abbreviations) to discover the effect of weeds on yields, density of planting was varied. The beneficial effect of the density of

The control of weeds in all crops is most important, given a chance that weeds will tend to establish themselves more quickly than the crop in its early stage. This can be so severe that producing a viable crop is no longer possible (Bakker, 1999, p. 179). In monocrops the farmer needs the (expensive) resources to prevent this occurring. In contrast, in traditional (small-scale and subsistence farms) intercropping systems, weed control is facilitated, whilst at the same time higher yields may be produced (Innis, 1997, p. 32).
• Erosion As under intercropping conditions a soil cover is provided at an early stage, the mechanical impact of falling raindrops on open soil is minimized, thus
preventing soil surface erosion (see Figure 4.11 on page 66). Furthermore root systems of crops in the intercrop system, being at different depths, will tend to hold the soil particles and aggregates together better than under monocrop conditions. The higher amount of decaying detritus on the soil surface plays a further and beneficial role in protecting the soil surface against erosion. A similar effect can be achieved in monocrop systems by adopting minimum tillage, strip cropping or trash farming (Figure 4.12 on page 69). This entails the direct planting of the new crop in the interrow of the harvested crop, or planting and harvesting crops in strips on hillsides (Bakker, 1999, pp. 152-154).
116 Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Trends of agricultural production and food security All this points to the need to protect the soil against erosion, wind and water-borne erosion being capable of doing considerable damage (see Figure 4.10 on page 61). It should be remembered that soil formation is a very slow and precious process, whilst erosion can remove topsoil very quickly. Modern farming practices, taking place in sizeable fields and tending to leave the soil unprotected for a (short) time between harvesting and establishment of the new crop, promote conditions for removal of topsoil, especially during that period. Commercial farmers are well aware of this, but sometimes pressure towards profits prevents them from investing in soil protective procedures, such as various methods of soil conservation. Minimum tillage, trash conservation and contour furrowing are examples of this. When considering how to proceed with the participatory farmer-led applied research, discussed in Chapter 5, soil conservation methods are important factors to be incorporated, especially on individual (small) plots on hilly sites.
Increase mechanization when labour is scarce This may be viable for the commercial small-scale farmer, but the subsistence farmer is likely to continue employing family labour (see page 113). Under conditions when labour is scarce, the subsistence farmer may see an opportunity to use his exchange entitlement (see Glossary, Entitlement) to greater effect.
Land substitution investments Under conditions where land is scarce, whilst labour is not a production limiting factor, the following land substitution investments can be of use (van der Meer, 1983).
Seed and variety selection. As indicated above the selection of seeds from home-grown crops in intercropping system may lead to less disease susceptible crops (see page 115). Purchasing seeds, especially produced for disease resistance and relatively high yielding varieties, can be beneficial, as shown by the ‘green revolution’. This form of intensification of petty commodity production in Asia increased opportunities for the ‘rich small-scale farmer household’, running a family enterprise farm (see Figure 2.2 on page 21). However, it increased risks for the ‘middle-income small-scale farmer household’, running a family subsistence farm, as new inputs in the form of seeds, fertilizer and irrigation water had to be purchased to achieve that potential increase in yield (Bernstein et al., 1992 p. 33). Such HYV (high-yielding variety) seed packages are scale neutral (see Glossary), which means that one could argue that such packages would compensate for persisting inequities in land distribution, which have long been a potential cause of social unrest. However, although in India the green revolution achieved an important national self-sufficiency in food grains by 1985, it achieved an uneven impact on regions, crops and rural livelihoods. The reason for this uneven impact is the water (irrigation) requirement of HYVs. Buying HYV seed packages, let alone affording the cost of irrigation, is beyond the budget of the family subsistence farm, involved in ‘simple reproduction’ (see page 20). On the other hand, and subject to a physical irrigation potential (see below) being available, the ‘family enterprise farm’ may be able to benefit. Gov-

118 Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Trends of agricultural production and food security these HYV seed packages, was that attention to pulses and the traditional coarse grains of millet, sorghum and maize, on which the poor rely more, fell behind. The effect of this on the nutritional balance of the relatively poor people was adverse (Bernstein et al.,1992, p. 57). From this it follows that from a food security point of view it is necessary to pay attention to traditional crops which can be cultivated and are within the budget [‘use value’ (see page 20)] of the ‘middle-income small-scale farmer’. The availability of water resources is an important aspect of this.
Irrigation. Due to the considerable variation in rainfall (and therefore in water resources for irrigation) in AFR as well as in SAS, applied research aiming at establishing or improving farm and farming systems by means of irrigation (see Chapter 9) should take place over as wide an area as possible. Feasibility studies should be set up in categories guided by an assessment of soil and water resources at basin and not at national level. This is because rivers, rainfall, soil patterns, landforms and landscapes ignore borders between countries. This means that the complexity of the relationship between the areas covered by water basins and the use of water for agricultural purposes will have to be taken into account when planning the landscape layout. An estimate of the number of these water resources which would be available for agriculture should be accompanied by an assessment of the amount of land suitable for arable agriculture and, as part of that, the land suitable for irrigation. Together with the irrigation water requirements, as determined by climate and cropping pat-
terns, the physical irrigation potential, as a means to intensify, that is increase yields and therefore production per unit area, could be assessed (see Figure 6.5). When considering the ever-increasing population pressure, irrigation, as a type of agricultural development could be seen as helping towards improving food security. However, the not inconsiderable danger of waterlogging and salinity over the long term, especially of terrain in the semi-arid and arid tropics, with annual rainfall of less than 1,000 mm, points to its limitations. Including irrigation in the applied farmer-led research, therefore, should be considered only for zones with at least 1,000 mm of annual rainfall and where the suitability of land for irrigation and water resources for irrigation are assessed as at least sufficient. To ensure that a gradual build-up of mineral elements in the irrigation water is avoided, the installation and cost of efficient drainage systems should be seen as an indispensable aspect of agricultural development based on irrigation. As this kind of development entails interference with the natural hydrological cycle of an area, the monitoring of the salt balance in the irrigation and drainage systems will require careful application of scientific knowledge by soil scientists, agronomists and irrigation engineers (Donnan and Houston, 1961, pp. 975-978). Realization that considerable losses occur during the conveyance of irrigation water to the sites where it is needed and avoidance of overirrigation, at the same time maintaining the correct salt balance in the root zones of the standing and growing crops [which may require the application of excess water to leach harmful elements out of that root zone (Hill, 1961)], is a most
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development 119
Chapter 6 Challenges Presented by Natural and Man-made Factors important aspect of this need for the application of scientific knowledge. A further aspect is the need for infrastructure in connection with the layout of drainage systems. National and regional policies will have to be concerned with the cost of irrigation and drainage development against the background of regional and national investment capacities. When considering these aspects, the benefit of small farmers using available water resources by irrigating their plots using hand-driven devices or small fuel combustion engines, may be a positive factor. The possibility to develop this physical irrigation potential therefore is a function of a composite of international agreements (regarding the use/distribution of water in the basin resources), national and regional policies, economic considerations relevant to the cost of irrigation and drainage development and capacity to invest. Sociological and environmental considerations, such as the effects of changing stream flows on human populations and downstream ecosystems, should play an important part in this. Examples of this are the construction of the Kariba and Cahora Bassa dams in the Zambezi river, constructed for the supply of energy. The man-made Kariba Lake extends upstream for some 280 km through the Kariba Gorge with a maximum width of 40 km. When this lake was filled, it required the resettlement of some 50,000 people and many animals. The Cahora Bassa lake and dam further changed the ecological system downstream of the Zambezi river, regular flooding of the Zambezi delta becoming a thing of the past, affecting the livelihoods of the riverine peoples.
All this points to the need for a serious undertaking to improve food security to be internationally driven, perhaps guided by organizations such as the ICRISAT and the FAO. A careful selection of so-called experts will be necessary. These experts must have the insight, or understanding of the problem situation, which ensures that the applied research is farmer-led. Were this not to be the case, the most valuable expertise and knowledge held about their own environment and ecological systems by the small-scale and subsistence farmers, might be lost. If this happens the undertaking would be doomed to failure, the motivation of the small-scale and subsistence farmer towards ownership of any (modified) farm and farming system being the most important driver towards its long-term success. The value of this local resource of knowledge and insight can hardly be over-estimated.
Organic and chemical fertilizers. As far as chemical fertilizers are concerned, the cost of obtaining these has an aspect quite similar to that for the use of machinery, in that the subsistence farmer may not be able to afford it. However, especially in SAS where land availability is more limited than in AFR, the use of fertilizer to maintain productivity may be pressing. This points to the value of organic fertilizers. In that context effective compost making techniques, converting waste materials (detrital biomass) into compost, are of significant importance to the smallscale and subsistence farmer. In this context also, the availability of microfinance, making it possible for these farmers to borrow money needed for the purchase of small quantities of chemical fertilizer, applied in conjunction with organic fertilizer, under a strictly managed regime by that farmer, could be of signifi-
120 Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
The impact of internal political instability cant use to the non-commercial farmer. In this regard the availability of microfinance seems essential.
6.5 The impact of internal political instability If resources are to be available to small-scale and subsistence farmers, an equitable availability of such resources is essential. This sounds naive and too optimistic in the context of the frequent occurrence of internal political instability. However, let us remember that the state factors of climate, time, potential biota, soil parent material and topography hold the future well-being of all living things, amongst which, we, as consumers of resources play a decisive role. Population pressure (see Table 6.2 on page 96) plays an all-important part in this, as does economic and social circumstance. However, the environment as expressed by its ecosystems sets the limitations within which human-made changes occur. When assessing a farming system with a view to increasing its productivity, understanding that ecosystems are linked and that production processes use these links, is essential. The links between solar energy, soil patterns, topography, moisture, nutrient flows and plant growth, form a continuum between atmosphere and biosphere. This continuum sets the boundaries inside which changes with respect to food security and landscape stability will have to take place. Human activities affecting this continuum will have to take note that this functions in a sensitive balance which must be respected. The link of all this to human activities in the context of food security and landscape
stability can be expected to function in a sustainable manner only if such activities take place in a secure working environment which is aware of this delicate link between atmosphere and biosphere. To make this work, a stable and active civil society will have to operate in an environment where adequate markets are available and which functions under good governance. In this context therefore it is of concern that in many developing countries ethnic conflict prevents civil society from functioning, threatening national unity. Examples of political instability being a source of economic stagnation are many. The famines in Ethiopia and Somalia in the aftermath of Ethiopian-Somalian wars, the collapse of the Ugandan economy and presently (2010) the collapse of the economy in Zimbabwe, come to mind (Szirmai, 2005, p. 473). Szirmai reports that researchers in quantitative studies of indicators of political instability and economic growth per capita established a negative correlation between these factors in 39 (!) countries in AFR (McGowan and Johnson, 1984) that is, at that time (1984), out of the total of 48 countries in this World Development Region. De Haan and Siermann (1993) point to the negative effect of frequent changes of government on economic growth in AFR. Ethnically polarized societies may have more difficulty in coping with competitive rent seeking (see Glossary for ‘Rent seeking’) by different groups, when regulators and their clients involve themselves in plans of mutual accommodation, or corruption (Easterly and Levine, 1997). If human activity is to have a chance to achieve the stated objectives of food security and a stable landscape, it appears

Otherwise this political instability may lead to economic stagnation. It is high time that the leaders involved realize that time is not on their side.

the destruction of these invaluable forests. Where logging can be justified a controlled and monitored system should be set up which regulates this clearly. All this may sound naive, but time is running out. Our international institutions and agencies should act before it is too late.
In this context of pressure on ecosystem productivity, it is essential to take account of the value of forests, which not only are carbon sinks but strongly influence rainfall patterns in so many tropical areas. Governments must use their power to stop

CHAPTER 7
The Competition for Resources for Food Production
7.1 The question of producing crops for food or bio-fuel In the long term the availability of food as well as bio-energy will have to be ensured. Because there appears to be abundant solar radiation in the WDRs of AFR and SAS it seems possible that at some time in the not too distant future the supply of materials in the form of cellulose for bio-fuels, could be a source of income for small-scale and subsistence farming communities in these regions.
FIGURE 7.1. Grasses in the Zambezi Valley.
Photo HB.
At present (2009) the subject of bioenergy is controversial and due to conflicting interests, complicated. If there is to be a sustainable (and growing) market for bio-energy which does not conflict with the pressing need to achieve food security, regulation, in the form of sound and binding international agreement, combined with appropriate costing of impact on ecosystem processes, will be necessary (Mol, 2008). The following notes, based on an article by Arthur Mol (Wageningen Update 1/08, pp. 16-21) attempt to put this into context. 7.1.1 Competition between crops for food and energy Newspaper articles and radio and television commentators sometimes allege that the drive for bio-fuels works against the need to achieve
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development 123
Chapter 7 The Competition for Resources for Food Production food security. There are examples supporting this (see below). However, we should ask whether the conversion of biomass into ethanol is wrong in principle, that is whether it will inevitably undermine the production of food. By 2007 the competition between the production of biomass for food and that for bio-fuels has been quite limited. In that year worldwide some 3.5% of the world food production was transformed into bio-fuel. In the European Union, where, due to the ruling that by 2015 25% of the fuel at fuel stations will have to be bio-fuel, the demand for bio-fuel has been increasing rapidly, the competition is still limited. In 2007 four and a half million tonnes of grain (cereals) were transformed into bio-fuels, or 1.8% of the total European consumption of cereals. However, at the same time grain stocks have reduced significantly, partly due to increased use in India and China (improving living standards) and due to unfavourable weather conditions (droughts) in Europe and Australia (Mol, 2008). 7.1.2 Market disturbance The market attraction for bio-fuels has in some cases produced an adverse effect on the availability of food. Some examples are as follows.
• Mexico As a result of the NAFTA free-trade arrangements, USA firms exported cheap maize to Mexico, mainly for use as cattle feed. This put small maize producers in Mexico out of business, resulting in a rise in local market prices for tortilla (small maize cakes). When the USA government began to subsidize the production of bioenergy, to support American farmers and to become less dependent on oil
imports from the Middle East, much of the maize, previously exported to Mexico, was used for the production of bio-fuels in the USA. As in the meantime Mexico had become dependent on those cheap maize imports from the USA, this development resulted in steep rises for maize (and tortillas) at the local markets in Mexico. By 2007 some recovery of local maize production had started (Mol, 2008).
• USA As it appears that the production of bio-ethanol from maize is more lucrative for the big firms than the production of cattle feed and therefore meat, the impact of this switch to bio-fuels is felt in the food sector (Mol, 2008).
• Europe The reaction to the scarcity of maize, in part due to the increase in consumption in China and India, to drought and the (as yet quantitatively low) switch to ethanol production, is to discontinue the compulsory allocation of arable land into fallow land. This might produce an additional 10 to 15 million tonnes of maize (Mol, 2008). 7.1.3 Crops for the production of ethanol Examples of where the production of crops for bio-fuels undermine food production are as follows.
• In the year 2006 some 14 million ha of Jatropa was planted in Mozambique. This crop is suitable for the production of bio-energy, using marginal land. Companies located in the western world buy this land for this purpose of producing bio-energy, at relatively low cost. As the crop is not suitable for
124 Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
The question of producing crops for food or bio-fuel human consumption, it is debatable whether the loss of this marginal land for the local farming community will adversely affect food production in this area in the longer term.
to government control. In this regard the protection of the farmer, working on a sustainable basis, such as can be found in the cane sugar industry in Brazil, is of considerable importance.
• Oil palm is an important supplier of
• With reference to the above examples,
vegetable oil for the food industry, but also a producer of bio-energy. Indonesia is rapidly becoming the biggest producer of palm oil in the world with a production of 17.4 million tonnes. To make plantations available for this purpose, tropical rainforest is deforested, thereby releasing enormous quantities of so-called hothouse gases. This is not sustainable.
a sustainable approach can be found in Brazil. Here an increasing demand for bio-fuels did not affect food supply. Sugar cane (an effective energy producing plant) factories are able to produce bio-fuels on a massive scale. Due to an advanced infrastructure and advanced technology and techniques, factories can change from bio-fuel to sugar production in accordance with market demand, virtually on a daily basis.
Oil palm trees can be cultivated successfully on marginal land. This can be found in AFR where some 50% of the land area consists of pasture land. Instead of allowing big powerful organizations to deforest land in the densely populated regions of SAS and East Asia and Pacific (EAP), smallscale and subsistence farmers’ communities in AFR and Latin America and Caribbean (LAC) should be assisted to put their resource of marginal pasture land to good use, that is to produce oil palm [or tree plantations, or grasses (see Figure 7.1 on page 123)]. This could be done by following the model of small farmers producing sugar cane as outgrowers, for delivery to a centrally located factory. An example is Mumias in Kenya, or for that matter Pelwatta in Sri Lanka. The agricultural production of the biomass as well as the industrially produced end product, would take place on a contractual basis, specifying quantities and delivery times as well as a price agreed between farmers’ representatives and manufacturers, subject
Also, and most importantly from a sustainability point of view, the Brazilian Government (in response to pressures from small farmer organizations) ensures that contracts protect the interest of the small farmers (outgrowers of sugar cane) to prevent them from being adversely affected by this large production. This can be done because there is the physical space for all, as there could be in (selected) areas of AFR.
• As far as the relatively short term future is concerned, the new technology under development (for instance at Wageningen and Utrecht universities) which converts cellulose from wood and grasses (see Figure 7.1 on page 123) to bio-ethanol, looks promising. Provided there is a stable climate for investment (good governance), this could be useful for Eastern Europe, AFR and LAC (Mol, 2008).

Chapter 7 The Competition for Resources for Food Production Comment 1.
Due to the pressure on the supply of food by the growing world population, the use of good arable land for the production of bio-fuels is not sustainable.

As indicated in Appendix 4 (see page 222), there is land in the form of pasture land available in AFR. Potentially some of that land might be suitaTABLE 7.1.
ble to grow oil palm. Other areas in that region and in LAC might be suitable more specifically for the production of grasses such as Rotboellia exaltata, Cynodon dactylon and Panicum maximum. This is in connection with the potential conversion of cellulose in grasses into bio-ethanol, mentioned above.

The densely populated WDRs of SAS and EAP may not have sufficient nonused land for any such enterprise, in contrast to the relatively sparsely populated regions of AFR and Latin America (see Table 7.1). This low population density however means that organizations capable of creating and maintaining the land in cultivation on a sustainable basis would have to be commercially oriented and equipped with the capital tools (factories, agricultural machinery) to meet market demand. 4. As there is ongoing and increasing population pressure (a major factor in the problem-situation of food supply and landscape stability), reasonably
(and potentially) fertile soils should be used for the production of food only. Marginal and non-forest land, such as available in AFR and Latin America, should be seen as a resource for the production of oil palm and later, once the technology of converting cellulose into bio-ethanol has been developed, the cultivation of grasses efficient in producing cellulose.

Where there is space, that is where open pasture can be used without adversely affecting small-scale and subsistence farming communities [(such as in Brazil - see above (due to low population density)], or where these communities can benefit from a new market, such as in Mumias,
126 Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
The question of producing crops for food or bio-fuel Kenya, sizeable plantation-like organizations might be able to exploit an opportunity for commercial agricultural production in the region of AFR without deforestation. Under those circumstances, the production of bio-fuels could assist in combating poverty. As a result the relatively closed small-scale and subsistence farming economy might become more open with more opportunities for economic development.
In this context it is noted that it might be possible to use surface irrigation. The data given in Table 7.2 refer to AFR as a whole. This region (as is the case too for other regions) includes several major basin groups, each of which might be exploitable by a number of countries. If big organizations intend to use surface (and where possible drip) irrigation to intensify the production of crops for biofuels, and are asked to do so, this can be done in a sustainable manner only if it recognizes that the water used comes from a common source (major) basin group.

To protect the ecosystems depending on these rivers (and groundwater), the irrigation water used for the purpose of producing crops for bio-fuels should be costed, which would promote the use of efficient irrigation systems such as drip irrigation.

An internationally coordinated study to determine this cost should be carried out. This activity should be motivated by the proposition that sustained functioning of bio-systems is of paramount importance if life is to be preserved.

Chapter 7 The Competition for Resources for Food Production If these ecosystem processes in the basin groups are to be protected, the use of irrigation water for the production of crops for bio-fuel may be viable only in exceptional circumstances. Also, any crop used for this purpose should have a high level of drought resistance. The costing of river stream and groundwater for the purpose of using it for the production of commercial crops for the production of bio-fuels, brings this water resource into the market. From the point of view of small-scale and subsistence farmers the advantages and disadvantages of any such market aspect should be given careful consideration. To protect their interests, the use of this common resource will require international agreements between the countries TABLE 7.4.
concerned and common management of that basin group with regard to main drainage and transport infrastructure matters. If this is not put in place, failure of the common use for food and bio-fuel crops of this invaluable natural resource, which, due to the ever varying state factor of climate, is unreliable, will occur. In that case the set-back for growing and advancing rural and urban communities in these regions would be such that they might have been better off without having to compete for water with organizations using it for the production of bio-energy. Some examples of major basin groups are given in Table 7.3, above. Details for some of the countries mentioned in that table are presented in Table 7.4.

7.2.1 The World Food Summit A useful benchmark with regard to the achievement of food security is provided by the World Food Summit (WFS). In 1996 world leaders met in Rome, and drew up an Action Plan. This related to the base year period 1990-1992 and stated that the number of undernourished people

region continue to live under this condition, with a disturbing increase by some 22 million people in Central Africa alone. In SAS, the number of undernourished people increased by some eight million during that time span. On the whole the percentage data, to which the World Development Goals refer, give a more favourable picture. From our point of view, however, those data are skewed under the influence of the rapid economic development in China.
The absolute number of undernourished people requires our attention. As shown in Table 7.5 (see page 129) the WFS target of halving this (target ratio = 0.5) by 2015 seems beyond reach. This quite appalling situation may well continue unless there is a radical change in the international political will and drive towards achieving sustainable food security. It is argued in this writing that small-scale agricultural development should play a major role in this endeavour.

Democratic Republic of the Congo As indicated in Table 7.5, progress for the sub-region of Central Africa has been falling behind all other sub-regions of AFR. Table 7.6 (see page 130) shows that this is largely due to the number of undernourished people in the Democratic Republic of the Congo having increased from 12.2 million by 1990-92 to 37.0 million by 2001-03. Internal conflict in that country, which began in August 1998, lasted until late 2002 with the withdrawal of invading foreign troops. This conflict significantly reduced national output and government revenue. As a result external debt increased, and more than 3.5 million people died from violence, famine, and disease. Due to the adverse operating environment, lack of infrastructure, uncertainties about the outcome of the conflict, foreign businesses curtailed operations. From early 2003 recovery has been slow and hampered by an uncertain legal system, corruption and lack of clarity in government policy (CIA, The World Fact Book - https://www.cia.gov/library/publications/the-world-factbook).
General comment When considering that food security relies on ecosystem processes, which require efficient soil and land management, which in turn require institutions such as agricultural services to perform effectively, situations, such as those referred to above, cry out for institutional reform. The situation which occurred in 2008 in Zimbabwe is another such example, promoting food insecurity, rather than food security.
In 2009 there are still some 800 million plus people suffering from chronic hunger, compromising health and productivity and therefore their efforts to escape poverty. It has a serious negative effect on the potential economic and social development of society (see Figure 4.3 on page 47). AFR is the most seriously affected WDR, some 33% of its population (some 200 million people) living under this burden by 2001-03. For Asia and the Pacific, that is including China and the SAS area with India, these figures were some 16% and 510 million. The primary responsibility to bring these figures down rests with individual governments. They are responsible for the essential stability of civil society by preventing this kind of serious political instability. 7.2.3 Independent control variables and agricultural production The regime imposed by state factors demands specific techniques for specific areas if the need for a secure supply of food is to be ensured. The overall connection between factors driving food supply is depicted in Figure 7.2 (see page 131). This shows various factors affecting both landscape stability and food security. With respect to the ongoing and rapid increase of world population, especially in the developing world, nations carry a heavy responsibility to ensure that the Millennium Development Goals (MDGs, see Appendix 8 on page 227) be met. This is a challenge of historical importance, facing especially the rich and developed world. In the longer term priority should be given to assisting the developing world to bring infrastructure, schooling and health facili-

Political will is needed in the developed rich nations to at last meet the commitment of 0.7% of GDP to official development assistance. This was pledged in a 1970 General Assembly Resolution and affirmed in many international agreements since, of which the March 2002 International Conference on Financing for Development in Monterrey, Mexico and the World Summit on Sustainable Development held in Johnannesburg later that year, are examples. Especially when taking into account that the developed world has become richer since 1970, it is disappointing that so little progress towards this objective has been made (see Table 7.7).
Although due to progress made by some of the ‘poor’ nations, it might be argued that less than 0.7% of GDP might suffice to meet the MDGs, for national and international stability, the matter needs urgent and positive action. International and national agencies must work together towards the eradication of hunger and poverty. The technology and resources are available. In the interest of motivating rural people to stay on the land, stopping the trend of ‘disappearing small-scale and subsistence farmers’ [Bryceson et al., 2000 (increasing urbanization)], it is high time that this intolerable

situation is turned around. At the same time political will and insight are needed in the developing world to place the interests of the general population ahead of personal interests of the most advanced groups in society.
In overall context. The availability of resources, suitable for use by humans, depend on the sustainability of ecosystem processes (see Figure 7.2). This means that in the long term human activities will be futile unless ecosystem processes are
protected. Amongst these processes are the formation of soils, microbial activity and moisture resources in soils, sustaining their suitability for food production. As indicated in Figure 7.3 above, the state factors of climate, topography, soil parent material, potential biota and time play a decisive role in this ecosystem ecology on which all depend. The greatest respect in protecting these ecosystem processes when competing for resources therefore is vitally important.

CHAPTER 8
Monitoring Intervention Strategies in Different Farming Systems 8.1 Introduction For the effective production of food, farming systems are pivotal. In Chapter 2 some of the economic aspects of small-scale and subsistence farmers’ households were considered (see Figure 2.2 on page 21). However, whether this is a ‘family subsistence farm’, a ‘family subsistence household’ or a ‘family enterprise farm’, people on the farm will regard their activities as forming a system in its own right. This will be affected by a variety of resources, such as availability of workers in the household, soil types and rainfall patterns, which will determine the crop plants which can be produced with a reasonable chance of success. The concepts of ‘farm system’ and ‘farming system’ as set out by Hall et al., 2001 will be used as a guide to describe major categories of farming systems for AFR and SAS.

8.2 Definitions described 8.2.1 Farm system The interrelationship between the components of a small-scale farm is complex. The performance of the unit depends on natural resources such as land, water and common property, such as ponds, grazing areas and forest. Climate, bio-diversity and human, social and financial capital play roles of major importance (Hall et al. 2001, p. 7). They define a ‘farm system’ as the aggregate of “the household, its
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development 135
Chapter 8 Monitoring Intervention Strategies in Farming Systems resources, and the resource flow and interactions at individual farm level” (my italics). The variation in resource endowments and family circumstances drive the performance of the individual household. The resource endowment of the farm is affected by the density of the local population, the distribution of resources among households and the effectiveness of agencies in establishing access to assets. The farm system is organized to manage the available resources with a view to producing food whilst also satisfying other household goals. Under low income (LI) to extremely low income conditions, such as occur in the World Development Regions AFR and SAS, a range of different activities may be undertaken. Cropping, the keeping of livestock, fishing, hunting, agro-forestry and gathering activities are examples. However, the household must be settled on land and manage it, whether owned, rented or managed jointly, to fall under the definition of ‘farm system’ (Hall et al., 2001, pp. 7-9). The external environment, comprising governance, policies and institutions, markets, infrastructure (such as distance to markets and roads to access them) and information linkages, affect the functioning of a farm. The off-farm economy links farms via commodity and labour markets. Perhaps above all the fact that rural and urban economies are interdependent is significant. Not only that this opens the possibility to ‘go out and work’ (see Figure 2.2 on page 21), adding to the small farm household income through offfarm activities, it opens the possibility for individuals of the household to establish contact with industry. This may be of particular relevance in densely populated areas, such as SAS (see Table 2.5 on page 30) (Hall et al., 2001, p. 9).
8.2.2 Farming system Hall et al. (2001, p. 9) define a ‘farming system’ as “a population of individual farm systems that have broadly similar resource bases, enterprise patterns, household livelihoods and constraints, and for which development strategies and interventions would be appropriate” (my italics). A farming system, following this definition can encompass many households. To avoid losing one’s way in this multitude and as a result of micro-analysis of farming systems in many developing countries, Hall et al. (2001, p. 11) decided to accept some degree of heterogeneity within any single system. Although significant sub-types occur, each broad system is characterized by a typical farm type. They base their classification on criteria comprising: 1.
The natural resource base available to the farm system under consideration. This includes:
• land grazing areas and forests as well as water;
• climate, determined to a large extent by altitude (temperature and rainfall) and latitude;
• landscape, in which soil type, slope and vegetation pattern play an important role;
• size of the farm, tenure and organization. 2.
The dominant pattern of farm activities and household livelihoods. Taking into account the main technologies employed when ‘doing’, which affect the intensity of production and the extent to which crops, livestock and activities are integrated, this includes:
• field crops; • livestock;

aquaculture; hunting and gathering; processing and off-farm activities.
Based on these criteria they distinguish eight categories of farming system as follows: 1.
Irrigated farming systems. This involves food and cash crop production.
2.
Wetland rice based farming systems. These depend quite heavily on monsoon rains, supplemented by irrigation.
3.
Rainfed farming systems in humid areas of high resource potential. These are based on crops, or on a mixed crop-livestock system. The crops may be root-crops, cereals, industrial tree crops (small scale or plantation) and commercial horticulture. TABLE 8.1.

Chapter 8 Monitoring Intervention Strategies in Farming Systems A total of 164 million ha, or 8% of the total land area of 2,127 million ha in 2002, were under annual cultivation or permanent crops (see Glossary). If pasture land, at 1,119 million ha, or 53% of the total land area, is regarded as potential arable land, some 13% (164 million ha) of the potentially total arable land (1,119 + 164 = 1,283 million ha) would have been under annual cultivation in 2002.
tively. It seems reasonable to assume that, as many (if not most) of the people in this low income group live on incomes of less than $1 per day, their food security is under constant threat. The viability of the farming system under which these households function therefore is of crucial importance.
8.3 Sub-Saharan Africa
It would appear that the region is well endowed with pasture land and that it ought to be possible to increase the agricultural land in cultivation at its expense. The agro-ecological zones are looked at in this context.

Agro-ecological zones in AFR with their vegetation and principal agricultural production are indicated in Table 8.2. This is
stated in broad terms only and should not be regarded as complete. The zones (Figure 8.2) are differentiated by the amount
138 Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Sub-Saharan Africa of rainfall received, which, in turn affects the lengths of the growing season. As rainfall tends to decrease along some continuous line from the rainforest near the
equator to the desert areas of the tropics of Cancer (Sahara) and Capricorn (Kalahari and Namibia) the zone boundaries are arbitrary.
FIGURE 8.2. Agro-ecological zones in Sub-Saharan Africa. From H. Bernstein, B. Crow, H. Johnson, Rural Livelihoods, Crises and Responses, Figure 8.1, (part) page 168. © 1992, The Open University. Used with permission.
They are helpful when considering farming systems in the context of rainfall and lengths of growing seasons. In general, rainfall intensity and distribution are more important to the farmer than total rainfall data. The rainfall pattern, that is its distri-
bution and intensity, is seasonal and uncertain in the semi-arid tropics and subhumid tropical uplands. This uncertainty limits agricultural productivity in these areas. Farmers have to concentrate their activity into short periods of considerable
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development 139
Chapter 8 Monitoring Intervention Strategies in Farming Systems activity, with a relatively high demand for labour, often leading to shortages in its supply. In these areas the family subsistence household (see Figure 2.2 on page 21) has difficulty in competing with the family enterprise farm in the labour market. This uncertainty places these farmers in a high risk situation of losing their crops in these regions of uncertain rainfall. Local variations in the moisture regime, as established by the varying rainfall pattern are understood by these farmers and exploited as far as feasible. Variations are relevant. Examples (given by Bernstein et al., 1992, p. 169) are those in:
• Altitude The highland areas of Ethiopia, Rwanda and Burundi and to an extent in Kenya and Tanzania, record higher rainfall and lower temperatures than the adjacent lowlands. This creates a longer growing period for crops and pasture and a greater diversity of crop choice in the sub-humid and semi-arid areas.
• Relief As water will accumulate in swamps and river flood-plains, the effect of rainfall is strongly influenced by relief. Such moisture reservoirs can be used for the production of crops once the rainy season has come to an end.
• Soil type The so-called ‘heavy’ soils have a higher moisture holding capacity than sandy soils, due to their relatively smaller particle size (clay content). Such soils generally occur more frequently in low lying areas, reinforcing the relief effect referred to above. From this it follows that local knowledge of these variations, which determine
a mosaic of soil patterns, varying over relatively short distances, is of considerable importance if successful farming is to take place. Such local knowledge is fundamental to farming strategies, which can vary widely. Examples of such ecological management in African farming, thereby minimizing the risk of sometimes drastic variations in rainfall patterns, are given by Bernstein et al., 1992, pp.166-169, 170, 171. In West Africa some 70% of the total population live in the moist sub-humid and humid zones (see Figure 8.2 on page 139). In contrast in East and Southern Africa this amounts to about half of the total population (Hall et al., 2001, p. 29). In the latter areas a greater percentage of the population, potentially, is subjected to droughts than is the case in sub-humid and humid regions of West Africa. The people involved in agricultural activities (in 2000 about 67% of the total population) accounted for some 20% of total GDP of the region. Hall et al., 2001, p. 30 report that this share of GDP is declining in more than one third of the regional countries, examples being Angola, Côte d’Ivoire, Eritrea, Lesotho, Ghana, Mauritania, Mozambique and Uganda. Increases occurred in Benin, Central African Republic, Cameroon, the Congo Republic, Mali, Niger, Namibia, Rwanda, Togo and Zimbabwe. In West Africa, expansion of the oil industry contributed to the decline over the last 30 years. In Southern Africa expansion of non-agricultural sectors contributed to this decline (Hall et al., 2001, p. 30). The vulnerable situation under which people in AFR live with respect to gross national income on the basis of PPP$ per capita is shown in Appendix 1 (see page 218).

Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development 141
Chapter 8 Monitoring Intervention Strategies in Farming Systems 8.3.2 Farming systems in AFR Hall et al., 2001, p. 34 identify fifteen farming systems, with their main characteristics and prevalence of poverty for this region (see Table 8.3). Due to their potential for poverty reduction and agricultural growth - main factors of importance if food security is to be achieved - they selected the following five systems:
• • • • •
Maize mixed system Tree crop system Irrigated system Cereal-root crop mixed system Agro-pastoral millet/sorghum system
Prior to referring to these in some detail (guided by Hall et al., 2001), it is necessary to look at the region-wide trends in AFR.
Region-wide trends in AFR • Population hunger and poverty Under the prevailing conditions of so much poverty (see Appendix 1), the projected increase in population by 78% in the next thirty years (Hall et al., 2001, p. 41) gives rise to concern. The urban population now reported as standing at 33%, is anticipated to rise to 50% of the overall total by 2030, notwithstanding economic contraction in the region. The HIV/AIDS pandemic is reducing the labour force in the prime working age group, but the net growth in population continues. The loss of productive labour and rises in medical and orphan care costs, result in a cost to the economy, which the region is unable to meet. Hall et al., 2001, p. 42 report that by 2001 the most affected farming systems had been the highland perennial and the maize mixed
systems, whilst the large-scale and commercial and smallholder system also had lost much of its skilled supervisory labour force. In the highland perennial system neglect of banana and coffee was due partly to HIV/ AIDS related labour shortages. In addition to this Hall reports that this disease is affecting government staff and private agricultural service providers resulting in a very high staff turnover and loss of investment and time in capacity building. During the final three decades of the 20th century the number of undernourished people in the region increased to an estimated 180 million people by 1995-97 (Hall et al., 2001, p. 42). It was reported that the average daily food supplies in Sub-Saharan Africa for human consumption by 1997-99 contained 2,195 calories per person, compared with 2,681 calories per person in the developing countries as a whole. This compares with 3,380 calories per day per person in the industrialized countries. For the period 2000-02 some 30% of the population (about 210 million people) of the region was undernourished [Human Development Report, 2005, Table 7, page 243 (UNDP)]. Although the energy intake is projected to increase by 18% by 2030, about 165 million people will still be undernourished. It is of concern that the region has a higher proportion of people living in dollar poverty than any other region of the world. Rural poverty accounts for some 90% of total poverty and 80% of the poor depend on agriculture or farm labour to support their livelihood. The total number of poor people in this

the accelerating global warming phenomenon. In particular, the farming systems in arid, semi-arid and dry subhumid areas are in danger of having to experience increasing frequency and severity of droughts. These are likely to give rise to crop failure, high and rising cereal prices, distress sale of animals, decapitalization, impoverishment, hunger and in the end, famine. These factors will be an incentive for households thus affected to try to cope with their cash and food shortages by cutting and selling firewood. This will make land degradation more incisive and accelerate the onset of desertification. Also, households might move temporarily, or permanently, to ‘better’, or less arid areas, creating conflicts between sedentary farmers and pastoralists.
• Natural resources and climate By 2001 some 400 million ha (nearly 17% of the total regional land area of 2,359 million ha) was covered by forest. In the context of maintaining the forest ecosystem intact, the current rate of deforestation stood at 0.7% (16.5 million ha) per year and the decline of this most valuable resource is expected to continue. The area under land degradation is increasing. The causes are complex, but aspects such as soil erosion, soil compaction, reduced soil organic matter, declining soil fertility and soil bio-diversity are linked with agro-ecosystems and local environments. Forest biomes are important with regard to global temperature balances and rainfall distribution and frequency in the context of TABLE 8.4.

The cultivated area, as represented by arable land, is estimated to increase from 228 million ha, or 9.7% of the total land area in 1999, to 288 million ha, or 12.2% of the total land area for the region by 2030 (Table 8.4). This slow annual expansion of 0.81% is attributed mainly to conversion of forests and grassland and shortening fallow, resulting in reduction of the
natural fertility of the soil. Due to population pressure the increase of arable land in use is projected to continue (Bruinsma, 2003: Table 4.7 page 133). If rotation periods and fallows continue to be shortened the end result may well be a reduction of yield. The farming systems, most closely linked with deforestation are the forest

Chapter 8 Monitoring Intervention Strategies in Farming Systems based system, the tree crop system, the root crop system and the cereal-root crop mixed system. The maize mixed, the highland perennial and the highland temperate mixed systems experience fuel wood shortages. In one way the forest based system might benefit from a reduction of excess moisture. Under these (improved) conditions, a population influx from areas next to the forest frontier areas, might be tempted to move closer to the forest. As such new settlers clear forests to plant their crops, the important resource base for carbon storage and energy creation, represented by forests, is affected adversely. A further increase of population and associated pressures in these areas would produce declining fallow periods, resulting in TABLE 8.5.
downward pressure on yields and increasing weed populations.
• Science and technology The FAO perspective on world agriculture towards 2015/2030 (Bruinsma, 2003) indicates data on crop production stated in Table 8.4 above. This shows that this substantial increase in overall production would be obtained through significant land expansion. Bruinsma, 2003, p. 133 indicates that empirical evidence for developing countries shows that such increases in output are achieved mainly through land expansion, when the potential for doing so exists. Set against the performance of the last 30 years (shown in Table 8.5) this projected doubling of overall production seems quite optimistic.

Sub-Saharan Africa doubful when seen against the data of Table 8.4 (see page 143). As most agricultural production in Sub-Saharan Africa may well continue to come from rainfed farming, farmers continue to be subject to the uncertainties of rainfall and day and night temperatures, which depending on agricultural ecological zones, delineate suitable growing seasons. Although increased production on heavy lowland soils, in humid and sub-humid tropics and on irrigated land may be expected, daily and yearly fluctuations in climate will continue to set decisive boundaries of production potential. Therefore, application of technologies suitable for the various areas and developed with (and by) the full participation of the farmer-communities in those areas, by means of exchange of ideas and demonstration of results (pilot projects, designed and managed by the farmers themselves), will become ever more important. This is a difficult task for well-trained (communication and social skills in addition to agricultural insight) and locally elected farmers’ representatives and extension workers. The animal and husbandry stock situation and production is shown in Table 8.6. The threat from tsetse infection usually is concentrated in the moist and sub-humid lowlands. Increasing numbers of cattle tend to be raised in the moist and sub-humid zones, where the root crop and cereal-root crop mixed systems occur. Although this might continue, farming systems in dry areas tend to have higher numbers of cattle than those in moist areas (Hall et al., 2001, p. 45).
During the time-span 2000-2030, livestock and poultry numbers are expected to grow moderately, consumer demand from urban areas being the driving factor (Hall et al., 2001, pp. 43-45). TABLE 8.6. Trends in livestock populations and output in AFR for the period 1970-2000. a

• Trade liberalization and market development The share of the region in world agricultural trade has fallen quite significantly since 1961, even though the absolute value of agricultural exports has risen. The sharpest fall occurred in Southern Africa, where the share in
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development 145
Chapter 8 Monitoring Intervention Strategies in Farming Systems world agricultural trade fell from 9% in 1961 to 3% in 1998. In this connection Bruinsma (2003, pp. 235, 236) reports that the structure of world agricultural trade has changed markedly. As far as the developing countries as a whole are concerned, in 1961/63 these countries recorded an overall agricultural trade surplus of US$6.7 billion. This disappeared during the next four decades until the end of the century, so that by the end of the 1990s trade was virtually in balance. Projections to 2030 suggest that this agricultural trade deficit for developing countries will widen markedly, reaching an overall net import level of US$31 billion by that year. The 49 LDCs (34 of which in 2003 reported a GNI per capita per year income of PPP US$765 or less are located in the WDR of AFR (see World Bank, World Development Indicators, 2005, Table 1.1) have been prominent in this respect. Their agricultural trade balance changed rapidly so that by the end of the 1990s imports were more than double the size of their exports. This trade deficit is expected to widen further, to the extent that (expressed in constant international dollars) by 2030 it will reach four-fold the level of the year 2000 (Bruinsma, 2003, p. 235). As far as AFR is concerned this trend reflects a significant fall in the share of agricultural exports in the total exports from the main areas of AFR. In some areas, such as West Africa, this may reflect a rapid increase in the export of other commodities, such as petroleum exports from Nigeria. In this context it is of interest that in Southern Africa, wine and fruit,
mainly from the Republic of South Africa, are important components. By 1998 cocoa was at 22% of total agricultural exports from Central Africa and between 12 and 25% from West and East Africa respectively. Cotton amounted to 5% in East Africa and 26% in Central Africa. Share of agricultural exports of total exports from the main areas of AFR. a

Cocoa and coffee are produced by the tree crop and rice-tree crop farming systems (see Table 8.3 on page 141) with a limited and moderate prevalence of poverty. Although the declining contribution of (some) agricultural exports from AFR for the period quoted is an important aspect for the future of rural livelihoods, cocoa, cotton and coffee are valuable agricultural commodities. Provided a good quality product is delivered, at a sustainable price, these commodities could find a valuable place on the world market. However the declining terms of trade (see Glossary) for these agricultural primary commodities have occurred at least as from 1980 and do not give rise to much optimism in this regard. This decline in primary commodity prices appears to be linked to changes in patterns in demand, production and trade in the high income countries. One rea-
146 Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Sub-Saharan Africa son may be that the consumption of services has been growing so rapidly during recent years. Some relevant points regarding the shift in the agricultural balance of trade, experienced by low income countries, are discussed in the following section.
• Policies, institutions and public goods The difficulty developing countries experience in trying to compete with subsidized surpluses disposed of by the OECD countries, is real. Subsidies by countries such as those of the European Union and the United States, led to agricultural overproduction. Subsequent disposal of surpluses put downward pressure on world market prices. This depressed export volumes and earnings from temperate zone commodities such as cereals and sugar. Although at the last (prior to 2005) round of WTO negotiations, the rich nations promised to reduce agricultural subsidies, they have increased them. These nations now spend over $1 billion a year on aid for agriculture in poor countries and just under $1 billion a day subsidizing agricultural overproduction at home (Human Development Report, UNDP, 2005, p. 10). These subsidies and the resulting overproduction drive down the world market prices for the primary commodities. As this reduces the income from excess production and the chance to improve one’s situation, the possibility for these subsistence farmers to get out of the poverty trap is severely limited. In addition, tax payments will be very low or altogether absent, leading to a zero public investment budget and absence of infrastructure building (Figure 4.3 on page 47).
In addition, developing countries added to this growing deficit in trade by taxing their agriculture directly through low procurement prices and quotas and indirectly through overvalued exchange rates and high protection rates for non-agricultural goods. Also, with higher incomes and more people needing food, the demand for temperate-zone products in developing countries increases at a rate at which domestic production could not keep pace. This rapid rise in demand for these temperate zone products occurred especially during the 1970s and early 1980s. During these years the oil boom afforded developing countries in North Africa and the Near East with the foreign exchange needed to increase imports of cereals, meat and dairy products, for which local production was low. With the decline in oil prices, food imports slowed down considerably in following years (Bruinsma, 2003, p. 237). Due to a variety of reasons, discussed in Bruinsma, 2003, pp. 236-240, the details of which fall outside the scope of this volume, producers and markets for tropical products continue to be beset by general problems. Where a rapidly rising supply is exported to saturated and fluctuating markets (such as have tended to occur with the commodities of sugar and coffee), prices tend to decline rapidly, often without a corresponding contraction in production. This imbalance between market demand and supply is due to many tropical agricultural crops being perennials. They are grown on a multi-year basis with a relatively large share of the total investment requirement spent in the early phase of the growing cycle
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development 147
Chapter 8 Monitoring Intervention Strategies in Farming Systems or investment period. To increase the return on such fixed investments producers, such as the family enterprise farm, or larger commercial entities, reduce variable costs, meaning lower wages for rural workers, such as coffee or tea pickers or cane cutters. In smallholder systems, involved in petty commodity, or for that matter elementary household production, a considerable decline in family income follows (Bruinsma, 2003, p. 241). Small-scale farmers in the developing world continue to be faced with rising costs of agro-chemicals, spraying equipment, tractor tyres, improved seeds, and so on. These costs still tend to rise more quickly than local (and international market) prices for primary agricultural products. This squeeze to which the smallholder farmer in the developing world is subjected, was illustrated quite vividly to the author when asked by a small coffee farmer in Vietnam how he was supposed to deal with the increased prices (he called this exported inflation) of needed investments such as his tractor tyres. In addition to the uncertainties of climate in dry and arid areas, as well as in more humid areas, and the impact of HIV/AIDS, TB and perhaps most importantly malaria in moist environments, unfavourable terms of trade are a factor of importance in preventing so many subsistence farmers in AFR to reach the first step on the ladder to development and economic growth.
Structural adjustment programmes (SAPs). The above rather depressing picture occurred notwithstanding financial assistance introduced in many countries
of the region under the conditions of SAPs. These programmes were driven by neo-liberal thinking, based on the thesis that the same rules of development can be applied from the most to the least developed country. The emphasis is on the individual and free play of market forces. According to this thesis economic decisions should be made by private individuals, the state providing only those goods and services (infrastructure) which could not be provided by the private sector (Jenkins, 1992). The main elements of SAPs are summarized below: 1.
Price distortions produce inefficiencies. When markets set prices, inefficiency is reduced through the removal of price controls. The programme assumes that this would achieve financial liberalization and less intervention in labour markets.
2.
A more efficient economy is achieved through trade liberalization, which means reducing protective tariffs. This is accomplished by removing import quotas, reducing tariffs and introducing realistic exchange rates.
3.
Reduction of the direct role of the state in the economy. This is done by means of privatization and cutting government expenditure.
Although many low income countries had fallen into economic crisis by the early 1980s as a result of economic mismanagement, which the SAPs were intended to address, the fact that policies and problems of governance in these countries were only part of the problems, was not (sufficiently) taken into account. Micro-effects, such as malaria, HIV/ AIDS, mountain geography and inadequate rainfall in many locations in these
148 Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Sub-Saharan Africa countries, have a more severe direct impact than for instance excessive nationalization of industry. Isolated small villages, where impoverished people live under harsh conditions without sanitation, clean water, potable water, and reasonable access to roads and markets, are other aspects. By the end of the 1980s there was some realization that liberalization alone was not an adequate response to the economic and social complexity of developing counTABLE 8.8.
tries. However, it appeared that the Millennium Assembly of the United Nations, which took place in September 2000, gave some impetus to the hope that the Millennium Development Goals (MDGs; see Appendix 8 on page 227) would finally begin to turn this situation round to better prospects. Unfortunately, as shown in Appendices 1 and 2 and by the Human Development Report, UNDP, 2005, it appears that by now (2010) these hopes have been dashed.

Hall et al., 2001, p. 46 report that the effects of SAPs are seen for instance in the roles of Ministries of Agriculture on which governments focused. Decentralization produced a situation in many countries, in which local government structures suffered progressively reduced budgets, resulting in cuts in staff and reduction in capacity, to deliver the services needed. They report that the immediate effect of
reduced public expenditure has been a crisis in the maintenance of infrastructure (e.g., roads and health facilities) and a reduction in the essential services to rural populations. Due to reduced budgets, imports were limited. Harvests without replenishment of nutrients, have depleted soils over a long period of time, specifically in the interior lowlands and coast,

Maize mixed farming system in AFR
By 2008-09, the vicious sequence of poverty-hunger-disease had deepened for many people in the low income countries, who continue to be in the poverty trap (see Figure 4.3 on page 47), (Human Development Report, UNDP, 2005).
Characteristics. This
• Information and human capital One aspect of SAPs has been a reduction in government spending on agricultural extension and training, reducing access for farmers to technology and market information. Hopefully, the internet will open channels of communication to farmers and their organizations. There is however a danger that due to a shortfall in education and facilities the poorest sections of communities will be left behind. This seems all the more important because if yield levels are to be increased to the levels needed if food security is to have a chance to succeed, relevant technologies need to be used. Human capital, as expressed in a reservoir of know-how, health and communication skills, may need to be strengthened quite significantly. 8.3.3 A closer look at a selection of farming systems in AFR The following observations are based on Hall et al., 2001, pp. 47-123. Due to their potential agricultural growth and poverty reduction, five farming system in AFR were selected for examination of strategic preferences. Main points are summarized in Table 8.8. By far the most important, in terms of agricultural population and cultivated areas amongst these five systems are the three mixed systems, located in the dry-subhumid agro-ecological zone (AEZ).
system comprises the main source of food for the East and Southern African region. Hall et al., 2001, p. 48 report that local and hybrid maize are grown for the dual purpose of subsistence and cash crops, often accompanied by minor crops such as pulses and oil seeds. Crops produced purely for their exchange value (see ‘Rich small-scale farmers’ households’ on page 20), are coffee, groundnuts and sunflower. As far as livestock is concerned, cattle are the most important, whilst crop-livestock integration (power to pull ploughs, dung to fertilize land) is very relevant. The main sources of poverty in these areas are landlessness, very small farm size, lack of oxen, low off-farm income and deteriorating terms of trade for maize producers. As shown in Figure 2.2 (see page 21), families involved in progressive reproduction on the family enterprise farm, as compared to those involved in subsistence farming, tend to have more resources in the form of more and better farmland (typically some 1.6 ha), more crossbred dairy cattle (some 2 or 3 head) and larger areas of cash crops. They tend to use more agro-chemicals, fertilizer and hybrid seed. Average yield would be 1.2 t/ ha for maize, 900 kg/ha for sorghum, 800 kg/ha for millet and 500 kg/ha for pulses. School fees and expenditure for clothes would be supported by the remittance from a son, working off-farm for cash income. These endowments would set up the family and enable them to have access to credit. In average to good years the family could feed itself. In years of drought, something would be available from some reserve.
150 Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Sub-Saharan Africa On the other hand the subsistence household farm is left behind. These are marginal farmers. Some forty percent of these households have no cattle, no regular offfarm earnings and no high value crops. Whilst producing local maize for home consumption, they are not in a position to buy agro-chemicals, fertilizers or hybrid seeds. During times of scarcity local differentiation intensifies (Hall et al., 2001, pp. 48, 49).
Trends and issues. In years prior to the introduction of structural adjustment programmes, agricultural extension work in the arid tropical zone of Kenya and Tanzania and in the sub-humid tropical uplands of Zambia and Malawi, concentrated on increasing maize production through the use of inorganic fertilizer and hybrid seed. This important work was specialist oriented and not much self-reliant farmer participation was involved. In an effort to stimulate competition, the introduction of SAPs cut subsidies on inputs and removed guaranteed market prices. Currency devaluation resulted in high-cost inputs of the resources of inorganic fertilizers and hybrid seed. They became uneconomical. Farmers now reverted to growing traditional varieties where available, or, for that matter replacing maize with sorghum and sweet potatoes. The use of purchased seed and fertilizers in areas which formerly exported maize, such as the Highlands of Tanzania and the Central Province of Zambia, has fallen due to smallholder maize growers reverting to low-input/low-output strategies. An apparent increase in poverty followed. Terms of trade for maize, as expressed by the input/output price ratio, deteriorated due to this trade and price liberation policy. The removal of input subsidies and
price supports and the discontinuation of the state purchasing maize, worsened this situation. Input supply services collapsed. whilst the response of the private sector was minimal. As per the neo-liberal policy, governments were advised to withdraw from seed production. But private companies were interested only in selling hybrid maize. Seed from open pollinated varieties can be saved by farmers for as much as three seasons before it has to be renewed. Due to lack of interest from private companies, finding good-quality open-pollinated seed became a problem, as was the case with access to credit and farm inputs. Hall et al., 2001, pp. 49-51 report that the rapid population increase meant that farm sizes fell to an average of 0.5 ha in many areas, which under adverse conditions is not viable without off-farm earnings. This reducing farm size induced shorter fallows resulting in loss of soil fertility (see Glossary). A prolonged use of inorganic fertilizers, without a balancing input of organic matter increased soil acidity. Feed shortage results in less livestock to produce manure. Less oxen on the farm for the supply of power, is a further adverse result of these worsening terms of trade. It seems likely that, at least in the short term, land degradation will spread, producing further downward pressure on crop yields. As a result the incidence and severity of chronic poverty is likely to increase. The declining stocks of maize surpluses and supplies by farmers to markets, threaten national and local food security.
Tree crop farming system in AFR Characteristics. The system is based on tree crop production, amongst which robusta coffee, oil palm and rubber are the
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development 151
Chapter 8 Monitoring Intervention Strategies in Farming Systems most important. These crops, together with off-farm activities are sources for cash income. Food crops, often interplanted with the trees, are the main staples. Amongst these, cassava, yam and coco-yam are prominent. Some basic data are presented in Table 8.8 (see page 149). As indicated in that table, livestock, being subjected to heavy tsetse infestation in many areas, is limited. As a result most land preparation takes place by hand. With respect to ‘domestic’ animals, pigs and poultry are the main species kept, whilst fish-farming is popular in some areas. Hall et al., 2001, pp. 55-56 report that industrial tree crops were first established by indigenous farmers by means of annual forest clearance. The amount of land cleared from forests depended on the availability of family labour to clear the forest, plant coffee or cocoa and grow food crops, consisting of a mix of cassava, coco-yam, cereals, pulses, all between the immature trees. After some 2 years, with the farm expanding, families would no longer be able to manage the newly cleared land as well as the plots created during the preceding 2 years. To solve this difficulty, farmers would contract the care of their second and third year coffee gardens to migrant workers in exchange for the right to inter-plant food crops among the trees. In due time the tree canopy would close, preventing the successful growing of such food crops on the forest floor. By that stage the coffee trees would bear enough fruit as an exchange value to pay for hired labour. The typical household in this farming system owns 5 ha of land, all of which would be under coffee in various stages of development. Cassava, coco-yam and cereal are inter-planted as food crops
between immature trees. The household also has a multi-storey homestead garden with fruit trees and vegetables. The wife may own some twenty free ranging, scavenging chickens. Each of the sons may own one or two goats and the husband may run a shop. This is a typical ‘family enterprise farm’ (see Figure 2.2 on page 21). Generally the family is food self-sufficient with a per capita income well above the poverty line (Hall et al., 2001, p. 56). In contrast to this relatively favourable situation, a poor migrant worker in this farming system and therefore working for the family who own the land, may have a wife and family back in the savannah, often working for the man’s father. This family depends on the migrant worker to cover its food and income deficit, even though it may be able to feed itself for 4 to 6 months per year. Even then the income derived from tending other people’s tree crops and growing food between the immature trees, is insufficient to lift the income of this migrant family above the poverty line. Commercial outgrower (estate) schemes tend to set the minimum plot size to 5 ha per grower. As farmers are expected to establish that area in one single year, this differs from the indigenous scheme, the short time span forcing some farmers into debt. Also, because there is no staggered planting, the vulnerability to pest and disease attack increases. This is another and important reason why so many farmers, working in these estate schemes, experience difficulty (Hall et al., 2001, pp. 55, 56).
Trends and issues. Population pressure on natural resources, declining terms of trade as well as of market share, the
152 Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Sub-Saharan Africa discontinuation of parastatal input supply and marketing services, and the withdrawal of agricultural extension and research work, are the main trends affecting the tree crop farming system in AFR. This shows in increasing poverty and growing social differentiation and conflict between the tree crop owners and migrant workers (Hall et al., 2001, p. 56). Strong international competition, putting a downward pressure on product prices, made this situation worse. Most tree crops in this region undergo a declining market share. The failure of the private sector to provide the services indicated above previously made available by the parastatals, as well as the take-over of state-owned agro-processing plants by large-scale private investors, contributed to the breakdown of services to smallholders. As a result of the inability of governments to support the cost of public extension services, the services to smallholder farmers had been significantly reduced by the year 2001. As a result of this policy reform the research on export crops is carried out by the private sector. This sector tends to concentrate on export commodities, largely ignoring other parts of tree crop farming and livelihood systems. Farmers’ problems to do with food crops and soil management (fertility) by 2001 were not being addressed (Hall et al., 2001, pp. 56, 57).
The irrigated farming system in AFR Characteristics. Some basic data are presented in Table 8.8 (see page 149). Fully mechanized and centrally managed schemes and the larger farmer-managed schemes, such as the traditional riverine and flood-recession based cropping
schemes are included. The latter may be found in small pockets along major rivers. Dug well-based irrigation in West African wetland also are included. The 2 million ha covered by these schemes support an agricultural population of some 7 million. It would appear that production from irrigated land in the region might increase quite substantially as a result of increases in yields (Hall et al., 2001, p. 58).
Trends and issues. Results from big public sector irrigation schemes in the region have been disappointing. Production increases have been below expectations, while low output prices, combined with high operation and maintenance costs have tended to make these projects unsustainable. Hall et al., 2001, p. 59 point to the Gezira Scheme in the Sudan, the Office du Niger in Mali, the Awash Valley Scheme in Ethiopia and the Jahali/Pacharr scheme in the Gambia. Efforts to restructure parastatal schemes on a commercial basis, or to hand over management to farmers in the expectation that operation and maintenance costs would become less, have largely failed. They report that on the whole smallscale farmer managed irrigation (SSFMI) has been more successful on the basis of high-value crops, such as vegetables. The difficulty is the lack of infrastructure, resulting in suitable markets being out of reach. Efforts are being concentrated on the existing schemes, but this, even with donor financing, mostly is beyond the farmers’ economic means. Hall et al., 2001, p. 60 report that the thematic evaluation of the IFAD (see List of Abbreviations) Special Programme for Africa concluded that the problem in SSFMI is a lack of “adequate social organization and cohesion”.
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development 153
Chapter 8 Monitoring Intervention Strategies in Farming Systems The example given by the experiment in farmer organization for self-managed development in the run down and conflict ridden irrigation system of Gal Oya in Sri Lanka, highlight the value of capacity building and participatory management in SSFMI. An environment enabling smallholder development was put in place through the introduction of durable organizations, based on farmer participation and bottom-up initiatives. The encouraging aspect of this intervention is that farmer initiatives were the driving factor for its success, to the extent that their commitment to their project was sustained in the long term (Uphoff, 1996). Examples in Mali indicate that, again subject to an ‘enabling environment’ having been put in place, farmers will strive for progress. Other encouraging work has taken place in Niger and Guinea Bissau (Hall et al., 2001, pp. 59, 60).
Cereal-rootcrop mixed farming system in AFR Characteristics. Similar to the maizemixed farming system, this system experiences 120-150 growing days per year close to the border in the north with the Sahel (semi-arid tropics) to 180 growing days in the south. Some basic data are presented in Table 8.8 (see page 149). Similar to the irrigated system, this points to a relatively low percentage of cultivated area of the agricultural land available. However, the agricultural population density, as expressed by the agricultural population over the total area available to the system, is approximately at the same level as for the irrigated system. Communications are poor, low altitudes and high temperatures predominate. The tsetse fly constitutes a pest which limits livestock, preventing the use of animal
traction in much of the area. Cereals, such as maize, sorghum and millet are important, but due to the lack of animal traction for land preparation, root crops, such as yam and cassava are more important than cereals. A wide range of crops is marketed. Intercropping is significant (Hall et al., 2001, p 62). A typical smallholder household active in this farming system would farm some 2 ha entirely manually. Maize, sorghum, yams, cotton would represent the main crops. Minor crops would comprise groundnuts, pigeon pea, cowpea, beans, sweet potato and squash. Fertilization occurs through the use of animal manure where available. However, frequently, cattle are not owned by the household, which might be limited to keeping some chickens and goats. Where cotton is grown, the purchase of some mineral fertilizer could be justified and inputs for this crop could be raised further through the use of some hired labour. Neither inorganic fertilizer nor hired labour would be used for the cultivation of maize or other food crops. This household would be food self-sufficient and in fact would have some exchange value goods as cotton, yams, cassava and vegetables. Due to poor market access some surplus perishables would be lost. To an extent this household could be regarded as a family enterprise farm (see Figure 2.2 on page 21). Poor households (family subsistence farms) amongst these slightly better-off farmers, would not produce cotton as an exchange of cash to pay for inorganic fertilizers and hired labour could not be afforded. Food deficit, likely to occur during the rainy season would be covered by household working for meals in other farmers’ fields. Further cash support
154 Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Sub-Saharan Africa would be earned by the husband when migrating to the forest area, working as casual labour for the industrial tree crop farmers.
Trends and issues. The difficulties confronting the people in this farming system, are exemplified by what occurs in the Guinea savannah. This covers large areas of the sub-humid tropical uplands, extending in a broad band through most West African countries (see Figure 8.2 on page 139). Due to low population density, lack of communications and labour shortages in the absence of animal traction, the area is relatively under-utilized, even though there is an abundance of agricultural land. The latter permits appreciable fallow in the crop rotation, yet a decline in fertility and an increase in the acidity level of some soils is apparent. Prolonged use of often acidifying inorganic fertilizers and a declining level of organic matter in these soils appears to be the cause of this. Declining terms of trade, due to declining input/output price ratios, present difficulties to farmers in the task of maintaining soil fertility. The decline of this vitally important soil property is demonstrated in this area by the increasing presence of Striga (witchweed). This is a much-branched scabrous herbaceous annual, parasitic on the roots of various grasses and often on the roots of maize, significantly reducing yield. The introduction and spread of improved and early maturing maize varieties in the 1980s and early 1990s resulted in an increase in the cultivation of maize and cotton, at the expense of food crops. Hall et al., 2001, report that this took place especially in the northern and drier part of the Guinea savannah. Government poli-
cies, which aimed at achieving national food self-sufficiency, facilitated this expansion by supporting fertilizer subsidies, seasonal production credit and parastatal marketing support. As the cost of this to governments was high and results disappointing, these policies proved unsustainable. The impact of SAPs, which introduced trade and price liberalization, led to a further deterioration of the balance of trade, as expressed in the fertilizer/maize price ratios. This made the production of maize less attractive to the small family enterprise farm. At the same time currency devaluation reduced urban demand for traditional foods like cassava and yams. This led to an expansion of the area under these traditional root crops, at the expense of maize. The increased production of these foods produced a reduction in prices. This meant that the impact of devaluation on the income of food crop growers was modest. The discontinuation of parastatal programmes that provided small farmers with seeds, fertilizers and chemicals at the start of the season whilst deducting the cost of these inputs from the marketing revenues, meant that the growing of cotton became less attractive to small farmers. They found it risky to buy fertilizers and agrochemicals in the absence of credit, rising fertilizer prices and stagnant or falling cotton prices. Reduced fertilizer application and attacks by pests and diseases resulted in a decline of productivity (Hall et al., 2001, pp. 62-63).

Chapter 8 Monitoring Intervention Strategies in Farming Systems tem. Food crops grown are rainfed sorghum and pearl millet, which, however, are rarely sold. Sesame and pulses on the other hand, sometimes are delivered to the market. Table 8.8 (see page 149) lists some of the main characteristics of this system. The table indicates that this is one of the important farming systems in the region. Animal power is used for land preparation, employing oxen along river banks, or sometimes camels in drier areas. Livestock is used for multiple purposes, such as the supply of milk and milk products for home use, transportation (donkeys and camels), land preparation (oxen and camels), sale or exchange, savings, bridewealth and insurance against crop failure. Pack animals, or animal-drawn sledges, rather than carts are used to transport crops. Interaction between crops and livestock is limited. Hall et al., 2001, report that although animals are used in the fields for ploughing and crop residues are grazed, fodder crops are not grown, whilst kraal (enclosure) manure rarely is applied to fields. The population lives in enclosed villages throughout the year. Part of the herd may migrate seasonally in the care of herd boys. Livestock ownership in the household largely determines socio-economic differentiation between households in the community. With respect to food security, when drought occurs in this dry to subhumid agro-ecological zone, only the upper stream households are reasonably secure. Some of their livestock can be traded for the grain they need. In contrast to this, households in the lower stratum, which do not have the resources to grow enough grain to feed themselves and have few livestock or other assets to exchange for grain, are chronically insecure in good
as well as in bad years. Households in the middle stratum are grain self-sufficient in good years, but in deficit during bad years. In average years, they have some animals to exchange for grain, but in bad years they are likely to suffer from serious food shortage. Hall et al., 2001, report that typically a household would have some 1.5 ha of cultivated land, which, however, would provide food production of only 93 kg per capita per yr. Millet or sorghum would occupy some 1.1 ha, some 0.2 ha would be cultivated for pulses and the remaining 0.2 ha would be planted to minor crops, such as vegetables, sesame or cotton. Yields, averaging 400 kg/ha for sorghum, 350 kg/ha for millet and 230 kg/ha for pulses are at a low level. The former two cereal crops would be grown basically for home consumption only, including, however, the brewing of beer. As to livestock, the family would own some chickens, 2 or 3 head of cattle and 5 to 10 sheep and goats. These together with cotton and the seasonal migration to the forest zone, would be the main sources for cash income. Families in this farming system are highly susceptible to drought. Successive droughts result in crop failure and food shortages. As a result grain prices rise, and livestock prices decline to the point of collapse. Weak animals often die and distress sales lead to the decapitalization of herds. In the extreme, poverty sinks into destitution when the family have consumed their stock of seeds and lost all their breeding animals. When this happens, planting or, for that matter, the rebuilding of herds cannot be undertaken, once the drought ends. Such families then are in desperate trouble.
156 Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Sub-Saharan Africa Quite apart from this constant threat of drought, problems specific to this farming system include:
• Acute shortage of water during the dry season, affecting people and animals alike.
• Shortage of seasonal grazing. • Physical isolation, due to lack of roads and access to markets.
• Disadvantageous terms of trade continue to affect the viability of crops and livestock.
• Lack of schools and local facilities. Bird and locust damage to crops, laborious de-hulling of grain, stock theft and encroachment of farming on riverine areas add to the complexity of life in these areas (Hall et al., 2001, pp. 66-67).
Trends and issues. A general reduction of rainfall during the past two decades, typified by erratic and insufficient precipitation, has resulted in low crop yields and the discontinuation of groundnuts and late-maturing sorghum. Some areas suffer from an acute shortage of drinking water and firewood. Shortened fallow intervals and long periods of continuous cultivation in the plains result in a reduced content of organic matter in the soil, demonstrated by soil fertility problems due to population pressure. Due to an expected further and rapid increase in population, this is an aspect which must be expected to become even more acute. The total population for the area, estimated at some 700 million for the year 2003, is expected to increase to some 883 million by 2015, 1,299 million by 2030 and 1,704 million by 2050. This represents 126%, 185% and 243% of the population of 2003 (Bruinsma, 2003, Appendix 3, Table A1). This projected
increase, as well as growing livestock populations will increase the pressure on resources in this farming system. If a breakthrough in technology related to soil fertility does not happen, soil fertility of the better crop land would be expected to decline. Furthermore, due to the lack of sound grazing management by communities, grazing resources (condition of pasture land) will decline in many areas. This means that under these circumstances, both chronic and transient poverty must be expected to increase. Drought, declining soil fertility, weed infestation (Striga) in cereals and cowpeas, pests and diseases in cowpeas and groundnuts and high cost and lack of credit to pay for inputs needed for the cultivation of cotton, may be listed as crop related constraints. Shortage of grazing during the dry season and the weak condition of draught animals at the time of the greatest need (to commence land preparation by the end of the dry season) are livestock related constraints. The seasonal ‘price scissors effect’ between grain and livestock further aggravates crop failure. This is demonstrated by the fact that in the (normal) ‘hungry season’, it takes three times as many animals to buy a bag of grain than in the harvest season. At the same time, when crops fail, grain prices increase rapidly, while livestock prices fall. Under those conditions more animals are needed to buy a bag of grain. Hall et al., 2001, state that this farming system has not been seriously affected by a withdrawal of the public sector (imposed by SAPs) from seed and fertillizer supply and crop marketing. The reason is that public extension services were quite unre-

8.4 South Asia 8.4.1 Characteristics of the region The eight countries included in this region are stated in Appendix 6 (see page 225). The basic data stated in Table 8.9 below are indicative for the region as a whole for the year 2002. Here, 214 million ha, or 45% of the total land area of 478 million were under annual cultivation. This remained virtually constant at some 44-45% during the decade from 1991-2002. In this region, the pasture and permanent land amounts to some 49 million ha in 2002, or 10% of the total land area of 478 million ha. The total population of the region, at 1,436 million, is more than 25% of the population of the developing world. The density of the rural population at 2.16 persons per ha, is higher than in any other developing region. A large proportion of the land comprises inhospitable terrain, concentrating the high population on 45% of the land area. This situation leads to severe pressure on natural resources in many areas. Basic information regarding the agroecological zones for this region is presented in Table 8.10 (see page 159). The monsoon rains benefit the humid or moist-humid lowlands, providing a growing season of more than 180 days per year. These areas in India, Bangladesh and Sri Lanka contain much alluvial soil. A high proportion of this land in under intensive rice cultivation and supports a dense population. The semi-arid and arid lowlands

The region as a whole contains some 74 million ha of forest, or 15-16% of the total land area, and 49 million ha (10%) of grazing land and some 214 million ha (45%) of cultivated land and permanent crops. This total area of 263 million ha, support a rural population of 1,033 million, or 0.255 ha per capita. As the total population, standing at 1,436 million in 2003 (Table 8.9) is expected to increase to 1,672 million by 2015, and 1,969.5 million by 2030 and to 2,258 million by 2050, the situation is not encouraging. The area under forest is important for the maintenance of fresh water resources. Its reduction in regions, such as for example Burundi, is of concern.

As indicated in Table 8.9, the majority of the population of the region live in rural areas (72%). Hall et al., 2001, point out that, although there has been an improvement in food security during the last 30 years, the FAO estimates that some 254 million people remain undernourished (Hall et al., 2001, p. 170). The HDI records an index of 0.628 for the region, compared with 0.774 for middle income countries (UNDP, 2005, Human Development Report, Table 1, p. 222). As shown in Appendix 2 (see page 219), only Sri Lanka (and the Maldives) have reached the level of lower middle income countries, at PPP$3,740 (in 2003), whilst the average for the region (eight countries) at that year stood at PPP$2,640.

and development of other sectors of the economy. This is most evident in India and Pakistan, being 27 and 24.6% of GDP, respectively (Hall et al., 2001, pp. 169171). 8.4.2 Farming systems in SAS Hall et al., 2001, p. 124 identity eleven major farming systems, describing their main characteristics, including principal livelihoods and prevalence of poverty (see Table 8.11 on page 160). As most of the poor people in the region live in four of these systems, Hall et al., 2001, p. 186 selected those four systems for closer analysis. Criteria used by them are based on agricultural population, the incidence of poverty, and an apparent potential for agricultural growth and reduction of poverty in the three decades after 2001.

Hall et al., 2001, p. 178 state that rapid urbanization and off-farm employment is expected to be an important factor in this significant change. In connection with this mobility, on-farm more extensive production systems, requiring less labour, such as wet rice and paddy (see Figure 8.3 on page 169) cultivation, rather than the cultivation of cotton, may become necessary to make time available for more costeffective work off-farm. More mechanization may be another aspect, also reflecting an increased asset position on the (small) farms and an increased area of land per worker. Women,
already important for the maintenance of the household, which includes onfarm work, may assume increasing responsibility for the management and operation of farms.
• Hunger (also re AFR) Bruinsma in his Table 2.3 shows that South Asia (SAS) and Sub-Saharan Africa (AFR) are the two world development regions with the highest incidence of undernourishment expressed as a percentage of population. AFR registered an increase in absolute numbers affected for the period 1990/921997/99 (Table 8.12).
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development 161
Chapter 8 Monitoring Intervention Strategies in Farming Systems That the absolute number of undernourished people in both these WDRs
continued to increase for the time span from 1990 to 1999 is not encouraging.

Due to the rapidly increasing total populations of both regions, it seems doubtful that the targets of reducing the absolute number of undernourished people, set by the World Food Summit in 1996 shown in Table 8.12 will be met (Bruinsma, 2003, pp. 32, 41). As far as SAS is concerned, the number of undernourished people stood at 303 million as an average for the period 1997-99, or 24% of the population. This is projected to decline to 195 million by 2015 and 119 million by 2030, or to 12 and 6% of the total population respectively. The average food intake per person per day in the SAS region was estimated to be 2,403 kcal per person per day for 1997-99. This is projected to increase to 2,700 and 2,900 kcal per person per day by 2015 and 2030
respectively. For AFR these numbers are 2,195 for 1997-99, 2,360 and 2,540 per person per day for 2015 and 2030 respectively (Bruinsma, 2003, Table 2.1, p. 30) (see Table 8.13). The data given in Table 8.14 below put this in a world context. This regional picture indicates that Sub-Saharan Africa, excluding Nigeria (where significant progress was made), failed to make progress in raising food consumption. Of the 12 countries with a population of over 15 million, the latest 5-year average (1995-1999) shows that the food consumption for most is lower than in the past. For some in fact much lower, namely the Democratic Republic of the Congo, Madagascar, Côte d’Ivoire, Kenya and the United Republic of Tanzania. Amongst these 12 larger countries, Nigeria, Ghana

figures for Sri Lanka are better at 7.6% (<$1 per day) and 50.7% (<$2 per day), but in the same overall range Nepal records 37.7% and 82.5%, Pakistan 13.4% and 65.6% and Bangladesh 36.0 and 82.8% (World Bank, World Development Indicators, 2005, Table 2.5, page 67).

Natural resources and climate As shown in Table 8.9 (see page 158), the area under permanent cultivation and permanent crops in the region of SAS is estimated at 214 million ha, or 45% of the total land area. As shown in that table, additional land could come from the ‘nonarable and non-permanent’ section. However, this would involve considerable investment and forgo some production from forests.
In this situation of population pressure on available land, it is disturbing that soil erosion in highlands and rainfed watersheds, already widespread, is made worse by overgrazing and the loss of nutrients from crop land. Soil degradation, due to overgrazing has occurred in areas of mixed and pastoral farming systems (Hall et al., 2001, p. 179). Slowly increasing, or stagnating yields in the intensive rice and rice-wheat farming systems are attributable to deteriorating soil physical condi-

phosphates) is an important factor. Nonattention to micro-nutrients and a declining use of animal manure do not help (Tran and Nguyen, 2001).

The geographic distribution of rather scarce water resources has dominated the development of the farming systems in the region. More emphasis on improving irrigation schemes and water use efficiency may be necessary. To achieve this, users, through participatory management and/or transfer of ownership to them, may be encouraged to improve the design of operating systems, as well as the all important aspect of good drainage. Better conservation and use of rainfall by means of improved water storage, as well as conjunctive use of groundwater, appears to have considerable potential (Hall et al., 2001, p. 179). On-farm activities, such as mulching, can improve the conservation of water. It is quite alarming that groundwater in some locations of the intensive rice and rice-wheat farming systems is scarce to
the extent that tube wells can be used to a limited degree only. Due to overdraught it is estimated that as much as one third of the irrigation blocks in these farming systems will be over exploited by 2020, subject to present rates of increase of overdraught continuing (Hall et al., 2001, p. 179). Limited availability of ground as well as of surface water for crop and livestock production also will hinder the rainfed mixed and pastoral farming systems. Increased demand from urban and industrial users of water will put agriculture at a disadvantage, except perhaps for high value crops. This limited availability of good arable land and water under an overall picture of population pressure puts forest resources under threat throughout the region. There appears, however, to be growing realiza-

Investment in this aspect will benefit not only local communities, but also society at large. The creation of village forest committees in parts of India is an encouraging example (Hall et al., 2001, pp. 179, 180).

Science and technology Although agricultural research has been strengthened much as a result of the organization of the National Agricultural Research Systems (NARS), increasing demand, coupled with changing consumer preferences and degrading resources in the region, continue to bring new challenges to the NARS. They say that, in order to meet these challenges, increasingly complex and diversified technologies will be required. The resource-poor small farmer is expected to remain the focus of publicfunded agricultural research. Many topics of specific interest to such farmers, such as how to improve low-input crop husbandry practices (minimum tillage, cost effectiveness) and how to minimize pro-
duction risks, need to be an integral part of that research focus. Partly as a result of the green revolution yields of paddy (wet) rice has increased by an average of almost 2% per year during the period 1997-2000. This has led to a production increase of some 2.5% over the last three decades to 184 million tonnes. This trend is expected to continue to 2030 (Hall et al., 2001, p. 181, 182). Wheat production in the past few decades has demonstrated the strongest increase amongst the cereals, with increases in yield of almost three percent per year, whilst land area under this crop increased by as much as 1.4% per year. This resulted in an overall increase in production of more than 250% to almost 100 million tonnes. This trend is also expected
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development 165
Chapter 8 Monitoring Intervention Strategies in Farming Systems to continue to 2030. However, areas harvested for coarse grains, such as millet and sorghum have declined in the past few decades. Small increases in yield have prevented absolute reduction in outputs for these crops. Fruits and vegetables, due to diversification of traditional cultivation patterns, similar to oil crops and wheat, have succeeded in achieving considerable production increases. Expansion in harvested areas has contributed to this to a significant extent. When considering growing demand from urban areas, in conjunction with improved infrastructure as demonstrated in better marketing and processing facilities, the potential of further increases in these fields is encouraging (Hall et al., 2001, pp. 181, 182). See also Table 8.16. In contrast to this generally encouraging picture for food crops, livestock production and consumption showed only moderate changes. Cultural factors influence livestock production and consumption and this has resulted in no more than moderate changes in the number of cattle, from some 230 million head in 1970 to 277 million head in 2000, representing an annual growth rate of about 0.6% over that time-span. Buffalo numbers have increased faster, to the annual rate of 1.9% over that period (Hall et al., 2001, p. 183). However, to meet urban demand intensive and large scale production of poultry has developed and this showed a strong increase at some 3.8% per year throughout the region, to reach about 742 million head by 2000. As a result of apparent improved production efficiency in recent decades, dairy output, as expressed in meat and milk, rose rapidly, the former by about 3.2% and the latter by an average of 4.2%
throughout that period of time, notwithstanding the moderate increases in numbers of cattle and buffalo. Increasing standards of living, expressed in rising incomes, the consumption of poultry meat and eggs, as well as sheep and goat meat, are expected to continue driving this rapid expansion (Hall et al., 2001, pp. 180-183).
Trade liberalization and market development Potentially this shows an encouraging picture for agriculture in the region and rural development in general. Some aspects are given below.
• Competition Intensified external competition for markets in basic staples such as rice, which, to an extent results from increasing opportunities for export, tends to promote diversification in almost all farming systems. SAS, having a dominant position in niche markets such as that for mango and cashew products, could develop a range of other competitive fruits. Due to markets overseas, created by the popularity of regional cuisine among expatriate South Asians, there is a potential for growth in processed foods. Advances in packaging and transport facilities are likely to stimulate exports to western markets of perishables, such as fresh breads and curries at competitive prices.
• Markets Expanding urban markets are likely to promote urban agriculture. The consumption of dairy produce, poultry products and lamb and goat consumption, is expected to increase quite rapidly. Vegetable and vegetable oil production also will expand. Remit-

South Asia tances from overseas work may well flow into agriculture and rural investment (Hall et al., 2001, p. 184).
Policies, institutions and public goods The quite optimistic picture painted in the foregoing paragraphs is constrained by the lack of infrastructure, especially the lack of roads in remote and sparsely populated areas. This increases the transport costs for needed resources (input) as well as for marketed products (output). Also the lack of health and educational services affect labour productivity adversely. From a poverty alleviation point of view, as most of the poor live in rural areas, it seems necessary to promote institutions (see Glossary), which value and indeed favour the rural and agricultural sectors, rather than the often politically more powerful urban areas and the manufacturing sector. In this context the accessibility of health and educational institutions to people who live in often (as yet) isolated areas, requires specific attention. The empowerment of rural communities, through decentralization, might assist in enabling them to ensure that such local institutions perform effectively. This is a change which appears under way, but will take time. Given the often close relationship between local communities and politicians, implementation of any such change needs to be monitored closely by the local community. The growing role of women in local council and district-level decision making is an important result of this decentralization. Due to inadequate land records in some areas, larger farmers have found ways to consolidate their holdings and this has limited the impact of the changes (Hall et al., 2001, pp. 184, 185).
Information and human capital To achieve the transformation required by the Millennium Development Goals (see page 227) by 2030, not only that the majority of farm households will have to be literate (seems achievable), but ongoing investment in education, as an institution of major relevance, will be needed. This is essential to equip workers with the skills to move to the off-farm economy, but most importantly, to ensure that those remaining in agriculture (so necessary from the food security point of view), will be ready to manage the emerging knowledge-based farming systems. Efficiency and productivity will have to be raised. Hall et al., 2001, p. 185, suggest that this kind of raised human capital would underpin the development of small-scale rural industry. An improved flow of information to farmers will be needed if knowledgebased commercial farming is to be successful. Support services involved with new technologies and markets will form an essential part in this. Conditions appear to be set for an information revolution to occur in this region, underpinned by the general availability of market information. Hopefully dissemination of technical information through multiple channels, such as cellular telephone communications, will redefine the role of agricultural extension (Hall et al., 2001, pp. 185-186). 8.4.3 A closer look at a selection of farming systems in SAS The following observations are based on Hall et al., 2001, pp. 187-204. Based on criteria for agricultural population, incidence of poverty, potential for agricultural growth and poverty reduction up to 2030, they selected four farming systems in this WDR of SAS for examination of strategic

In terms of cultivated area, the most important are the rice-wheat farming system and the rainfed mixed farming system, both located in the dry sub-humid agro-ecological zone (also see Table 8.8 on page 149).
Rice farming system in SAS Characteristics. At 36 million ha, this farming system covers some 7.5% of the land area of 478 million ha (Table 8.17). At 22 million ha, some 61% of the area under this system is cultivated. Hall et al., 2001, pp. 186-188 explain that this system covers much of the wetland rice area. In this paddi system farmers or sharecroppers tend to cultivate their own land. Tenants and sharecroppers farm small areas, of 0.3 to 1 ha, with a limited number of medium to relatively large owner-operated farms, which may be 4 to 10 ha or more.
Supplementary irrigation may be required in the monsoon season, whilst full irrigation is necessary in the dry season. As most of these areas are close to urban areas (markets), off-farm employment, induced by the limited resource base of these farms, is common. As rice, as a food staple is very important, whilst access to these farms may be relatively easy, extension services are well developed. As much as three harvests per year require almost continuous paddy cropping. This labour intensive work leaves limited fodder resources to support ruminants, except for paddy straw. These ruminants include milk and draught animals, buffalo and in the drier areas, oxen. Notwithstanding these limitations, the system contains a significant proportion of the region’s cattle. Close to large urban

areas, the sale of milk supports dairy cattle. The wetland rice areas (black) occur in southern Bangladesh and South Punjab, as well as in coastal zones of Tamil Nadu and Kerala, the wet zone and some irrigated parts of Sri Lanka (Figure 8.4). But much diversity occurs, with a transition to the rice-wheat system in northern areas of Bangladesh and in the Bihar State.
Households are inclined to depend on a limited crop income. This, however, is vulnerable to fluctuating yields. Failure to find work in the neighbourhood is a major source of insecurity. Institutions such as health care and employment guarantee schemes generally do not function with sufficient effectiveness, adding to this overall insecurity for the small farmer community (Hall et al., 2001, pp. 186188).

Trends and issues in the rice farming system. Hall et al., 2001, pp.188, 189 report that due to population increase and the loss of land to urban expansion
land availability is expected to decrease. Land degradation, soil erosion and salinization add seriously to the problem of lack of food security, made even worse
170 Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
South Asia due to increasing water scarcity in agriculture. The latter is due to ever increasing demands from domestic and industrial sectors. It is encouraging that the education level of both men and women is expected to increase with a more widespread use of existing and new hybrid rice varieties. Parallel to this, intensive pressure on land will reduce the availability of fodder for draught animals and promote the use of two wheel tractors, also for local transportation. Increasing labour costs will further tend to promote mechanization of farm operations such as sowing, weeding and threshing, which, however, points to declining profitability of rice production on these small-scale farms. Declining terms of trade will tend to bring about diversification to include dairying and aquaculture. This, together with population pressure, tends to force male farm household members to seek to increase their income from off-farm sources. This in turn involves an increased burden of farm work for the women in the household. There is a chance that on average there may be some slow improvement in household food security and some reduction in poverty. This could follow some improvement in public infrastructure and other institutional empowerment. Especially transport, educational and health facilities may well improve. Decentralization of decision-making to the district and local levels will play a significant part in this. Stronger farmer organizations and the empowerment of women are important in this regard. With respect to the latter, the enforcement of the one-third quota of women in local office, will increasingly
take note of the need for women. Due to declining budgets for agricultural research and extension in the public sector, the private sector, farmers’ organizations and technology sharing are expected to play an increasingly important role.
Micro-finance. The introduction of the instrument of micro-finance (see Glossary) has played a successful role in many cases in supporting farmers’ communities with the acquisition of finance to support their activities. It seems likely that there will be more seasonal and permanent outmigration, accompanied by some growth in the off-farm rural economy. In summary one might say that the evolution of the system is driven by low and declining paddy prices, the effect of which is enforced by increasing labour costs. This results in lower use of fertillizer and declining yields and rice production. Sometimes this aspect is made worse by governments to keep rice prices low to meet the demands of urban populations. Price controls and monopoly purchases were then used as means to achieve this. Subsidies on fertilizers, irrigation and other inputs offset these effects to a degree (Hall et al., 2001, pp. 188, 189).
Rice-wheat farming system in SAS Characteristics. At 97 million ha, this farming system covers some 20% of the land area of 478 million ha (see Table 8.17 on page 168). At 62 million ha, some 64% of the area under this system is cultivated. As shown in Figure 8.4, this system (3) occupies a swathe of land from northern Pakistan through the Indo-Gangetic plain, including the Terai of Nepal and the Gangetic plain in Uttar Pradesh, Bihar and West Bengal, to end in northwest Bangladesh. Hall et al. 2001, pp. 192, 193, state
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development 171
Chapter 8 Monitoring Intervention Strategies in Farming Systems that characteristic for the system is a ‘summer’ (monsoon-season) wetland rice crop and a ‘winter’ (cool, dry season) wheat crop, sometimes followed by a ‘spring’ vegetable crop. In this farming system, the occurrence of poverty and food insecurity among sharecroppers and landless agricultural workers is widespread. Some form of irrigation tends to support the system. Livestock, although more common than in the rice farming system, often are made up of large cattle herds, owned by landlords or business men. The cattle feed on stubble after harvest, to return to wastelands or uplands during the crop season. Technical progress, such as is evident in improved varieties of rice as well as of wheat, combined with the use of irrigation and fertilizer, resulted in increased production. Unfortunately recently stagnant or declining yields of the system have occurred. These are the subject of a research programme by the Rice-Wheat Consortium (RWC) for the Indo-Gangetic Plains. As a result of that work, introduction of minimum tillage has enabled the small farmer to minimize the time from rice harvest to wheat sowing, thereby enabling him (her) to benefit more from the soil moisture remaining after the monsoon rains, resulting in production increases. In addition the reduction in the use of fuel lessens the (financial) burden on the farm household (RWC report 1995). However, the western areas of the system in Pakistan usually have fewer animals and more use of machinery. Hall et al., 2001, p. 193, report that the system in these areas, which are not located in flood-prone districts, vulnerability is due to price variation, crop pests and inability to earn sufficient off-farm income.
The difficulty for this farming system is that wheat sowing must follow immediately after the rice harvest if wheat yields are to be at all satisfactory. This problem has become more pronounced with the expansion of the system into areas where groundwater is more difficult to obtain. This means that farmers have to wait and transplant at the onset of the monsoon, thereby losing the advantage of the ‘cool, dry’ season. Traditional varieties are more adaptable to drier conditions, but these are slow maturing. As a result, too often wheat is sown late, thus depressing yield due to the by that time high temperatures affecting plants as they set seed (Hall et al., 2001, pp. 192, 193).
Trends and issues in the rice-wheat farming system in SAS. Due to permanent and seasonal out-migration of young people, it is likely that the average farm size will not decrease. The pattern of producing rice and wheat on the same farm may become more important, as, through its diversity it provides some protection against crop failure. Due to urban growth, land close to the urban centres will increase further in value and it may well be that absentee ownership will increase. The practice of sharecropping, which is based on a traditional and largely invariable operating system, within which it is difficult, if not impossible, to promote innovation, will come under pressure. The decline in soil productivity, due to excessive reliance on faulty application of mineral fertilizer, may have been halted to an extent as a result of improved methods of soil preparation, e.g. minimum tillage. The build-up of soil salinity and sodicity in the dry, western areas of this farming system, has been caused by poor water management.

Rapid expansion of the number of tube wells in some areas such as western and central Uttar Pradesh to millions of private well owners, has contributed to this. Conventional regulation through licensing and monitoring were shown to be ineffective. As exploited aquifers are depleted and degraded, groundwater dependent irrigation farmers have to convert, sometimes to the full extent, to rainfed farming, with an increase in mechanization (primary tillage) and a disappearance of draught oxen. The enterprise pattern is shifting to more dairy, feed grains, crop by-products and where major urban markets are near, large scale. industrial poultry production. Notwithstanding these difficulties, food security and higher household incomes are expected to be achieved by most farmers by the year 2030. Improved infrastructure as seen by better roads may become evi-
dent. Decentralization may lead to better governance with women obtaining an improved role in local governance. Farmers’ organizations may be strengthened and a modest growth in the off-farm rural economy is foreseen (Hall et al., 2001, pp. 194, 195).
Highland mixed farming system Characteristics. At 65 million ha, this farming system covers some 13-14% of the land area of 478 million ha (see Table 8.17 on page 168). At 19 million ha, some 29% of the area under this system is cultivated. Hall et al., 2001, pp. 197, 198 report that this system is concerned with the cultivation of a number of cereals, legumes, tubers, fodder, fodder trees and livestock. With regard to the latter, the bovine population amounts to some 45 million head.
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development 173
Chapter 8 Monitoring Intervention Strategies in Farming Systems As indicated in Figure 8.4 (see page 170), the system (4) stretches in a long narrow band over upland areas of Pakistan, India, Nepal and Bangladesh and a small area in central Sri Lanka. Mineral fertilizers are costly, or unavailable in the remote areas, the flow of nutrients to cultivated land is limited to a supply from grazing cattle, or from the cutting of fodder trees from woodland areas, located higher up. In more accessible areas, successful vegetable production, such as potatoes, can result in an intensive system of commercial production. The area in central Sri Lanka, near Kandi (see page 173) with good infrastructure in the form of roads leading to urban demand, is a good example of this. Another example is in the hills of Himachal Pradesh, where sizeable apple orchards can be found. Ruminant livestock, providing milk, draught power, manure and cash income, have an important place in this farming system. The communities living in these areas, tended to practise shifting agriculture, mostly as tribal societies, which now, however, have adopted a more permanent form of agriculture. Hall et al., 2001, p. 198 report that “the most important issue overall is the ever-increasing population pressure, caused both by reduced mortality rates and by immigration by ‘lowlanders’, which can make the already fragile system unsustainable”.
Trends and issues in the highland mixed farming system in SAS. Here population pressure and the need to cultivate land have led to continuous cultivation on steep slopes, often with thin or poor soils. A lack of agricultural extension assistance had meant that agriculture
has not improved. Impoverishment has been the result, aggravated by poor soil and water conservation. Women have to walk ever further for their water and firewood; “erosion and the decline of soil fertility can pose grave threats to household survival” (Hall et al., 2001, p. 198). Young people often leave to find work, resulting in an ageing local population. The move from shifting to sedentary cultivation has brought the issue of land tenure to the fore, most families having settled on common land or within forest boundaries. Families become a law unto themselves, social cohesion being absent or poor, as is the normal hierarchy of village councils or headmen. Individual land ownership disputes are difficult to resolve, whilst agreement on the use and management of common land often cannot be found. This lack of social capital stands in the way of development, essential if improved technology, land use guidelines and the application of soil and water conservation methods are to be accepted and used. Small areas of cash crop or livestock production have provided a basis for improvement in the whole of the farming system. The fruit areas near Kandi in Sri Lanka, the apple orchards in Himachal Pradesh, citrus in eastern Nepal, virus-free potato planting material in Pakistan and vegetable seed in Nepal are quoted as examples. Production in these examples was associated with well-organized collection and marketing, founded on sound technical and marketing information. Milk production has expanded, often as a result of improved access. The private sector often is involved (Hall et al., 2001, pp. 198, 199).
174 Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
South Asia Rainfed mixed farming system Characteristics. At 147 million ha, this farming system covers some 30% of the land area of 478 million ha (see Table 8.17 on page 168). At 87 million ha, some 59% of the area under this system is cultivated. The system is located virtually entirely in central and southern India with a small area in Sri Lanka (see Figure 8.4 on page 170). The system (5) in many small areas is supported by irrigation from (storage) ‘tanks’, reducing vulnerability to drought. This has been further enlarged by the use of tube-wells. As the system is mostly dependent on rainfall, it is exposed to a relatively high level of risk, making the introduction of new technology difficult. In the cooler northern areas of the system, wheat, barley, vegetables and fodder crops are produced. In the warmer areas of southern India, maize, sorghum, finger millet, vegetables, chickpea, pigeon pea, green and black gram and groundnuts are more the custom. Some small areas may produce soybean, rapeseed, chilli, onions and sesTABLE 8.18.
ame, mainly as cash crops. Where irrigation is available, double cropping may be practised. The largest share of cattle, sheep and goats is supported by the farming system, generally providing the main part of the family’s cash income. As most areas are too remote for commercial milk production, this income derives from the sale of adult animals or young stock. With improving infrastructure in some areas, dairy production is taking on a bigger role. The area covered by the system is larger than that covered by the rice-wheat farming system (see Table 8.17 on page 168), but because of its heavy reliance on rainfed cropping, a much lower population density is supported (Table 8.18). Chronic poverty, of which seasonal vulnerability is critical to livelihoods, results in subsistence agriculture. In addition to this, infrastructure in the area is poor, aggravated by remoteness from markets. Agricultural extension services tend to be weak and farmers employ traditional production methods.

Additionally, land tenure is often an issue, putting farmers in a position of disadvantage when it comes to acquiring credit on money markets.
Trends and issues in the rainfed mixed farming system in SAS. Even though access to markets is difficult, enterprise patterns in the system have been changing. Market forces drive the system to become more commercial, with
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development 175
Chapter 8 Monitoring Intervention Strategies in Farming Systems some increase in the use of external inputs and mechanization. Vegetable and dairy production may expand further. Oil seed production benefits from subsidies. However as agriculture and urban demands expand, pressure on water resources will increase. Soil fertility may decline and land degradation, again due to population pressure, may well increase further. Owing to improved access to markets, livestock productivity, aided by stall feeding, is expected to increase. On balance household food security may improve, although in drought years there is likely to be a shortage of food.
Some improvement in transport facilities and social services is likely. In the face of reducing public agricultural research and extension services, farmer organizations will take on more of these services. The role of women may be strengthened in some areas.

Small-scale and Subsistence Farmers’ Households and Selected Farming Systems 9.1 Typical households 9.1.1 Some households in SubSaharan Africa (AFR) The following describes households in some of the farming systems discussed in Chapter 8.

HB.
A middle stream household would comprise husband, wife, four children, an older relative, and orphans. They would live on a dispersed homestead. They would have an area of some 1.6 ha under cultivation, comprising 1 ha of maize, yielding about 1.2 t/ha, and sorghum, yielding some 900 kg/ha, 0.1 ha of cotton, and the remainder under other crops. The household would own two to three head of cattle and use oxen for ploughing the land. They would benefit from off-farm income earned by one son working offfarm and contributing to household income. Their food sufficiency would be adequate in average to good years, but in deficit during drought years. They would live mostly above the poverty line. A poor household in this farming system often would have a (widowed) woman, heading the household. That household would crop less than 0.5 ha. This household would own no cattle, but perhaps a goat and some chickens. Its income would come from casual labour for other farmers. Food sufficiency would be inadequate and the household would

Chapter 9 Small Farmers’ Households and Selected Farming Systems live mostly below the poverty line (Hall et al., 2001, p. 49).
A typical farm household in the tree crop farming system in AFR A typical family in this farming system comprises a husband, wife and sons. They cultivate some 5 ha under coffee in various stages of development. Their food crops are cassava, coco-yams and cereals inter-planted between the immature trees. Also it has a multi-storey homestead garden with fruit trees and vegetables. Young sons and the wife might each own some goats. They would benefit from off-farm earnings made by the husband owning a shop or some other form of business. A farmer may have a fishpond. Generally the household is food self-sufficient and earns a per capita income above the poverty line. A poor migrant worker in this tree crop farming system would have a family left behind in the savannah. That family would live with and work for the man’s father. They would be able to support themselves for some 4 to 6 months per year and deal with the deficit by means of migration. Yet, the overall income is below the poverty line (Hall et al., 2001, p. 56).
A typical farm household in the cereal-root crop mixed farming system in AFR In this system a typical household would farm some 2 ha, growing maize, sorghum, cassava, yams, cotton and some minor crops. Cultivation would be by hand. A significant part of organic manure would be provided by Fulani herds passing through the area to graze on crop stubble. Quite frequently the household would not own cattle, but a few chickens and goats
would be kept. Notwithstanding their high cost some minimal amounts of fertilizer and pesticides would be used, but no mineral fertilizer would be applied to food crops. The household would be food selfsufficient and some surplus might be available for sale on the market. The main sources for this cash income would be cotton, yams, cassava and vegetables. Unfortunately some of this would rot due to perishability and poor access to markets. Because of lack of cash needed for the purchase of inputs, a typical poor household in this system would not produce cotton but devote their available land to the production of food. It would meet its food deficit during the rainy season by means of working for food on other farmers’ fields. During the dry season the husband would earn some cash by migrating to the forest zone, doing casual work for industrial tree crop farmers (Hall et al., 2001, p. 63).
A typical farm household in the agro-pastoral millet/sorghum farming system in AFR In this system a typical household would have just about 1.5 ha to cultivate, limiting the level of food production to some 93 kg per capita per year. This means that even in years when crops do not fail, the household is in a food deficit position. The cultivated crops would be some 1.1 ha of millet or sorghum and 0.2 ha of pulses, the remainder being used for vegetables, sesame or cotton. Yields, at 400 kg/ha for sorghum, 350 kg/ha for millet and 230 kg/ha for pulses, are low. With regard to livestock, the household would own a few chickens, and two or three cattle, or five to ten sheep and goats. Cash sources would be this livestock, cotton

season, retains two thirds of the production.
Socio-economic differentiation is driven by ownership of livestock, whilst some 40% of households, apart from a donkey, have no livestock at all.
In addition to this sharecropping, the household may own two goats and some ducks and chickens. Together with a relative (kinship being important) they may share the purchase and ownership of a milking buffalo. Both husband and wife work for some 120 days per year on large farms in their area, as well as (if possible) in a local factory.
A poor household in this system would produce sufficient food for just 2 to 6 months, depending on the rains. In these cases household income would derive for 40% from casual labour on other farms, or the sale of beer and firewood. When the rain fails reliance on casual labour would be more pronounced (Hall et al., 2001, p. 67). 9.1.2 Some households in South Asia (SAS) The following describes some of the households in some of the farming systems discussed in the section on some selected farming systems in South Asia (see ‘A closer look at a selection of farming systems in SAS’ on page 168). That text dwells on the environment in which so many of the people concerned live and work.
A sharecropping farm household of the rice farming system in SAS A typical poor sharecropping family household in this system would comprise five family members, cultivating 0.4 ha of irrigated land in West Bengal, India. The monsoon rice crop would be followed by a second irrigated rice crop and by a short vegetable crop. Modern rice varieties would be transplanted in both seasons, yielding some 1.9 and 2.4 t/ha. Of this the sharecropper retains one third. The landowner, having provided the land, a draught buffalo and inputs, which include fertilizer to some 150 kg/ha of nutrients and chemicals for about four sprays per
This household has a low annual income, is vulnerable to low crop yields and a lack of earnings as a result of lack of work opportunity or sometimes sickness (Hall et al., 2001, p. 187).
A typical poor sharecropping farm household of the rice-wheat farming system This sharecropping household, comprising two adults and three children may cultivate 0.8 ha of irrigated land in Uttar Pradesh, India. Here the monsoon rice crop is followed by a wheat crop and sometimes a short vegetable crop. The modern rice variety may produce 1.9 t/ha, the sharecropper retaining two thirds. The wheat crop averages some 2.5 t/ha. The family owns a share in a milking cow, the milk being delivered daily to a village milk collection centre. Apart from effort and time, the cow is relatively cheap to own in that it is fed straw, weeds and other herbage cut from the field and path perimeters. Both adults work as labourers, for some 160 days per year, on large farms which are nearby and in a local factory. The combined average income for this household falls just beneath the international poverty line (see Glossary). It is vulnerable to low crop yields, loss of the milk

Chapter 9 Small Farmers’ Households and Selected Farming Systems cow and lack of income from labour (Hall et al., 2001, p. 193).
A typical poor farm household of the rainfed mixed farming system The family may comprise six members, cultivating, in Madhya Pradesh, India, some 3 ha of land. They grow 1 ha of sorghum as a post rainy season crop, yielding 1.3 t/ha and some 0.5 ha of chickpea, yielding 0.85 t/ ha, 0.2 ha of pigeon pea, yielding 0.5 t/ha, 0.3 ha of groundnuts at 0.6 t/ha and 0.2 ha of rapeseed yielding 0.7 t/ha. They own two head of cattle and several goats and poultry. The household has a combined average income just beneath the international poverty line. It is vulnerable to crop failure (Hall et al., 2001, p. 204).
9.2 Strategic priorities The potential of meeting the international development goals of halving hunger and poverty by 2030 depends on sustainable strategies for small-scale agricultural development. 9.2.1 Sub-Saharan Africa Hunger and poverty in this WDR still increase, which is distressing perhaps especially as the majority of poor people depend on farming for their livelihood. It appears that the Millennium Development Goals (see page 227) will not be met. Agricultural production, meeting the pressing needs of the rural poor, is insufficient. This, in part is due to policy, economic and institutional environments not being conducive to creating the incentives needed to get this agricultural production off the ground. This is evident in too many areas in there being an urban bias in development, agriculture being over-
taxed, the supply of rural public goods being less than in other regions. Investment in agricultural research and extension has been unsatisfactory. At the same time terms of trade have been declining. Other worrying aspects are poor governance, civil strife and degenerating law and order in some areas of the region. In too many places this is aggravated by gender inequality, low levels of schooling and HIV/AIDS. However, a relative abundance of natural resources in substantial areas of the region could provide the basis for agricultural development in favour of the poor. To create the incentives for this, an adjustment of national policies, reorientation of institutions and provision of goods and services in a reasonably secure environment, would be necessary. Based on their analyses of the major farming systems, Hall et al., 2001 provide a scheme for the strengthening of strategic priorities regarding policies, markets, information, technology and natural resources. An indication of five major household strategies, aimed at getting away from poverty are included (see Table 9.1). The achievement of this ‘goal’ is all the more important in view of a high population growth rate, while the number of poor increases. Rural poverty accounts for 90% of total poverty and some 80% of the poor continue to depend on agriculture, which, once again highlights the need for small-scale agricultural development (Hall et al., 2001, p. 72). From the above it follows that a reduction of household vulnerability is not enough by itself to meet the need to eradicate extreme hunger and poverty in the region (MDG No. 1; see page 227). Apart from the other seven development goals stated in the MDGs, five important

strategies, are required (Hall et al., 2001, p. 80).

These are: 1.
Sustainable resource management This should aim to deal with land degradation, declining soil fertility and low crop yields, with the objective of achieving soil recovery and improved productivity. The work concerned involves
• farmer-centred
agricultural knowledge and information systems to document and share success (see Chapter 1), • resource enhancements, for instance small-scale irrigation and water harvesting, • participatory applied research, centred on technologies which bring indige-

Chapter 9 Small Farmers’ Households and Selected Farming Systems nous and scientist knowledge about conservation agriculture, agroforestry, integrated pest management, and croplivestock integration together (see Chapter 5), • strengthening of resource user groups. 2.
Improved resource management
•
If a viable resource base for small family farms is to be created, access to agricultural resources should be improved. The concept of ‘good governance’ is relevant here too. This concerns market-based land reform, adjustment of legislation, strengthened public land administration, functional community land tenure.
3.
Increased small farm competitiveness
• • •
• • • • • •
This should strengthen the capacity of small-scale farmers to exploit market opportunities. This comprises improved production technology, diversification, processing, improved production quality, production for niche markets, strengthening support services, which includes also market agencies based on public-private partnerships.
4.
Reduced household vulnerability
•
This entails household risk management and aims to reduce its exposure to natural and economic shocks, prevalent in Sub-Saharan African agriculture. This includes drought resistant and early maturing varieties and hardy breeds, improved soil moisture management, insurance mechanisms strengthening traditional risk spreading mechanisms.

5.

Responding to HIV/AIDS The impact of HIV/AIDS is severe. To bring this under control action is required which includes information campaigns, supply of cheap but reliable condoms, affordable treatment, land tenure reform which results in preventing widows from losing access to and control over land and household property when their husbands die, agricultural training for AIDS orphans, safety nets strengthening the efforts of rural communities to support AIDs orphans.
9.2.2 South Asia The region’s economies are undergoing rapid and generally beneficial change. By 2003 the size of the economy, as expressed in GDP, was rising at a rate of 7.5%, compared to 3.9% in AFR. The per cent growth per capita for 2002-03 stood at 5.7% and 1.9% respectively (World Bank, 2005, World Development Indicators, p. 24). This has affected farm systems in the area profoundly. Population density (298 persons per sq. km, versus 30 persons per sq. km in AFR) and relatively little fertile soils with a good moisture regime potential, has led to intensive agriculture. The considerable length of time during which this intensive agriculture has been practised, has resulted in substantial resource degradation in some areas. Even so, the rapid economic growth has enabled agricultural research and support systems to generate growth in food production faster than population growth. The result, during the past decade or two, has been a reduction of the number of people living in poverty and undernourishment.
182 Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Strategic priorities Although, driven by changing technologies, improved access to markets and more effective institutions, this positive pace of change may increase, it seems unlikely that the MDG 1 goal of halving the incidence of hunger and poverty by 2015 will be met. Note that here we consider US$ and not PPP$. In 2002-03 the
average GNI per capita for the region stood at US$510 (World Bank, 2005, World Development Indicators, p. 24). If the MDGs are to be met, further effort by farm communities as well as by public and private organizations is required (Hall et al., 2001, p. 205).

(2) Assessments refer to poor farmers only. (3) Agricultural population weightings by system are derived from Table 8.3.
The potential for poverty reduction within this WDR is indicated in Table 9.2 for each farming system. Although the potential for growth due to its high value products may be highest in the tree crop farming system, the overall impact of this on poverty reduction for the region is likely to be small, the system involving just 1% of the agricultural population of
the region. Improvement in the rice-wheat farming system, which involves some 33% of the agricultural population, and where poverty is widespread and severe, would have a significantly higher impact. From the relative importance of the five household strategies indicated in Table 9.2, diversification to high value enterprises, including local processing of farm
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development 183
Chapter 9 Small Farmers’ Households and Selected Farming Systems produce, would be a main source for the reduction of hunger and poverty. The next important factors appear to be increased off-farm income and intensification of existing production patterns and then exit from agriculture. There is not much potential in increasing farm sizes. However, when considering the importance of food production in this most densely populated region [(298 persons per sq. km (World Bank, 2005, World Development Indicators, p. 24)] where by 2003, 72% of the total population lived in rural areas, one sees that, at least for the foreseeable future, agricultural development will remain an important driver in programmes to reduce hunger and poverty. In this process important resource degradation challenges progress. Linkages to the off-farm economy need to be taken into account. Four strategic objectives could promote activities towards achieving MDG target 1 [(see page 227), (Hall et al., 2001, p. 214)]: 1.
Improved water resource management
•
If the intensification and diversification of production and the depletion of resources for the surface as well as the underground water schemes, are to be supported, improved water resource management must be regarded as essential. Elements which come into play here are efficient technologies of resource management, conjunctive use, regulatory measures such as water charges, water users’ association, watershed protection by means of soil conservation works.
• • • • 2.
Strengthened resource user groups
Extensive water and land degradation in plains and hills to protect water resources must be corrected. The strengthening of resource (land and water) user groups would be one way of attempting to achieve this. Elements concerned include • resource management groups for watershed management in hill and mountain areas, • range of management groups in pastoral areas, • policies encouraging effective common property resource management. See Uphoff (1996). 3.
• • •
•
4.
• • • • •
Re-oriented agricultural services Agricultural research, education, information and extension systems must involve small-scale and subsistence farmers fully on a PLA (participatory learning and action) basis. Elements include models for joint public-private service provision, pluralistic advisory services, delivery, where appropriate via the internet, of market and technical information, incorporation in higher education systems of interdisciplinary learning and approaches. Improved rural infrastructure Especially in the low potential and highland areas in this region transport and health investments are of high return and beneficial to the poor. Elements include roads, drinking water, schools, health facilities, effective models for private sector participation.

FIGURE 10.1. Dual tension in projects for rural development.
A participatory or peoplecentred approach to development may be faced with problems in addition to those discussed in previous chapters. An example of this is the tension between the logic of the agency considering an agenda, based on upward accountability and planning, whilst delivering a sustainable project, and the logic of the staff working on the ground facing potentially conflicting demands for participation from local and donor interests. Such a ‘dual logic’ tension (David Mosse in Cooke and Kothari, 2001, p. 25) may occur. Some factors which may play a role in this are indicated in Figure 10.1. In that context this final chapter attempts to set out some broad outlines of which those involved with processes aimed at achieving food security in a stable landscape, must be aware. In the situation of a changing world and the enormous demands population pressure places on the need for food security, political will
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development 185
Chapter 10 International, National and Local Agencies - Conclusion should be mobilized to initiate and sustain action. Flexibility and willingness to learn is an essential attribute for all actors in this process.
10.2 Tensions What do donors and recipients respectively mean by participation? 10.2.1 Cultural environment and participation If a participatory process with rural small farmers in low income countries is to have a chance of success, the potential impact of the local cultural environment on such processes should be understood by those involved in the intervention. Cohesive group relations may be most important in environments, where culture as defined by local history is a driving factor. Personal relationships, kinship and connections form the bases from which the power of main decision makers derives. Less powerful members in that society may be inclined to accept an unequal distribution of decision-making power. Participation in such communities may mean that people (participants) with less local power are quite happy to leave decisions to those with more local power. The local political context is likely to play an important role here and will influence what form participation by smallscale and subsistence farmers takes. Because these cultural environments may differ over relatively short distances, donor staff employees working in the field must demonstrate a willingness to learn and listen. In this respect personal contact and trust between development staff and small farmers is most important. Staff may find that the level of participation by various groups will vary over time. This may be the case when it comes to moni-
toring the effectiveness of the project. Time will be needed to determine (with flexible boundaries) who is going to do what. That the situation will be fluid must be accepted. In view of all this it is likely to be difficult to set out appropriate levels of participation. Starting small with a core of farmers involved in experimentation (see Figure 5.3 on page 81) and expanding this to a limited number of farmers to be involved in planning, joint experimentation and the designing and implementation of an appropriate monitoring process, may be an approach promising some result. Based on such results, collaboration with the general farming public who appear to be prepared to adopt defined measures on the basis of sharing monitoring and participatory findings, might be sought (Guijt, 1998, p. 14). The success of a development project is likely to depend on the project’s staff’s ability to incorporate their (long-term) findings into the design of the project (John Hailey in Cooke and Kothari, 2001, pp. 88-101). 10.2.2 Communication Project staff working for institutions (local and international) and donors, should get a firm feel of the impact of the traditional and cultural background under which farm systems (see ‘Farm system’ on page 135) function. The role of women in sustaining effective communication between small farmers is especially important. As women in WDRs often are instrumental in maintaining effective farming households, the availability of micro-finance, to be used directly by female small-scale and subsistence farmers (see ‘Micro-finance’ on page 171) may play a role (see ‘Poor subsistence farmers’ households’ on page 21).
186 Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Tensions 1.
To get their views about family relationships and producing food on a small-scale farm, communicate with groups of women who work and live as small farmers.
2.
Ensure that these views are defined. It will be difficult to arrive at some form of consensus. Powerful and eloquent small farmers (female or male) may think they know what the project staff would like to hear. To strengthen their personal influence they may be inclined to try to influence others by pushing their assessment of the project aims forward. In this setting, a difficulty for the project staff will be to find out to what extent a sustainable participatory approach is feasible. As the emphasis of the project is on delivery, their may be tension between on the one hand the aim of the project agency to deliver a sustainable programme, with the operational procedures this requires, and on the other hand the participatory logic with its emphasis on local level and integrated planning and capacity building. Project staff will be faced with this duality (see Figure 10.1 on page 185).
3.
Demonstrate to local authorities that small farmers can be instrumental in the process of achieving food security. For this purpose successful small-scale farmers who live and work in the region might be asked to hold a series of open days. Local officials and international development project staff should ascertain what can be learnt from such local experience.
10.2.3 Higher education Assess the impact of higher education study programmes at national universities on local rural communities. Graduates of
such programmes should be able to find professional satisfaction and a good salary in working with (participate) local smallscale and subsistence farmers in being involved in small-scale agricultural development. 1.
Ensure that study programmes are directed towards working with local farming communities.
2.
Ensure that salary levels of graduates working in these communities are at least on the same level as those earned by colleagues working in governmental posts.
10.2.4 Terms of trade Update the present knowledge and insight into what the situation is in which communities find themselves in rural areas of WDRs. The local food prices as compared to world market prices should be central to this enquiry. 1.
The World Food Summit (see Table 10.1 on page 189) and the World Trade Organization (WTO) should put the industrialized nations under pressure to hasten the dismantling of their agricultural support programmes.
2.
More attention should be devoted to the circumstance that a new world is upon us. This means that low income countries may be left further behind in the not too distant future. Political will must be gathered to ensure that the terms of trade (see Glossary) become more favourable to such countries.
10.2.5 The physical infrastructure Assess the impact of infrastructure with respect to the availability and access to roads and markets for each area. 1.
Local governments and farmers’ organizations should open their doors
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development 187
Chapter 10 International, National and Local Agencies - Conclusion for local and international civil engineering organizations to survey rural areas. Projects, supported by international financial institutions, should work towards improving accessibility to markets wherever appropriate. 2.
Consult with the local small-scale and subsistence farming community about the existence and ease of access to markets. This is a factor affecting the extent to which local farmers may wish to increase their production of crops for food.
3.
Where state factors (see Glossary) of climate, topography, parent material and potential biota point to favourable conditions to produce a specific crop(s), consider whether a market can be created to provide an outlet for such crops. The Mumias Outgrower Scheme is an example (Beevers, 1980).
Establish or update existing systems to ensure that the most recent information regarding population density, food production and consumption, is available on an ongoing basis. 1.
2.
Population density, population growth, and poverty may have a direct impact on the sustainability of livelihoods. Therefore, the effect of these factors on the livelihood of small-scale and subsistence farmers in low income countries should be monitored on an ongoing basis. The effects of projects to improve food security should be monitored against the background of population growth and poverty.
Find out how in the opinion of local small-scale and subsistence farmers food production can be increased. The use and efficiency of farm systems in the context
of intercropping and the social implications of agricultural practices are relevant in this regard. 1.
The extent to which intercropping (growing two or more crops at the same time in a field) is used in specific areas could be a useful indicator of food security in such areas. The frequency of intercropping, in terms of area and number of farms, should be monitored against the occurrence of food insecurity.
2.
Is there an awareness amongst smallscale and subsistence farmers of land equivalent ratios (see Glossary)? Can a monetary benefit be demonstrated?
3.
How can social differentiation be minimized? Some farmers may not have the resources to obtain materials.
4.
Can a consensus be found amongst small-scale and subsistence farmers that intercropping may be beneficial?
10.3 Work together The situation arising from population pressure and changing state factors affects everybody. 10.3.1 Introduction As a result of massive and ongoing changes in information and communication technologies, underpinning major changes in technological and social developments, humanity is facing a new world. The impact of these changes is apparent from people moving from less developed to more developed parts of the world. Increasing world population in the less developed world is an important driver for this phenomenon. As this evolves at an increasing pace, deteriorating food security and land degradation produce a high cost in human capital worldwide.
188 Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development

We have the technologies and the resources required to implement urgent change. Political will should be mobilized by the international community, demanding sustainable action by governments of developing and developed countries alike. Governments should work together with donors, United Nations agencies, international, national and local agencies, civil society and the private sector. The vitally important objectives must be to achieve the WFS and WDG (see List of Abbreviations) targets and in fact go beyond that. The prevalence of undernourishment is still high, the trend of the number of undernourished people increasing (‘Up’)
in many areas (Table 10.1). Amongst these AFR, mainly as a result of poor performance in Central Africa, has shown further deterioration for the period from 1992 to 2005 (Table 10.2). The number of undernourished people in India (as yet) remains striking. This is disconcerting as an increase in the overall production of agricultural commodities by small-scale farmers in WDRs depends on their supply of energy, or the sufficient supply of food and clean drinking water. To get out of this circular argument it has been argued on these pages that the following factors are required.
190 Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Work together • Stable national governance creating an environment in which farmers’ organizations and national agencies can work together implementing appropriate but already existing agricultural technologies. Participation by small-scale farmers’ organizations and subsistence farmers’ groups, supporting applied agricultural research by local universities and extension workers would be one aspect of this effort.
• Micro-finance being available in a manner attractive to small-scale and subsistence farmers. Examples of work done by NGOs in the field of micro-finance show that this can be done. Petty commodity production (see ‘Rich small-scale farmers’ households’ on page 20) should become more wide spread.
• Improved infrastructure leading to better and easier access to markets. International and national institutions should work together in this kind of massive civil engineering project.
• Improved and more stable terms of trade. These should be such that the small-scale and subsistence farmer is stimulated to produce agricultural commodities for international trade. This should be an aim for the World Trade Organization to achieve as soon as possible. All this could improve the standard of living of the small-scale and subsistence farming community, enabling them to purchase good seed material and perhaps above all, to begin farming suitable pasture land, such as that available in AFR (see Table 2.4 on page 28). A rise in the standard of living in rural areas could put less pressure on food prices to the benefit of urban populations. Increased invest-
ment in agricultural production would be to the benefit of society. Small-scale agricultural development should be given due attention as one of the main drivers for overall development. Efficient use of an increased land area suitable for agricultural development would be central to this. 10.3.2 The process of action The participatory approach has been central to this writing. The concepts of ‘reversal of learning’ and ‘people’s knowledge’ have been used in support of the argument that rural development programmes must be sustainable. Sustainability may be promoted if the people themselves have ownership of such programmes. This ownership might be acquired through the involvement mentioned above. Upon completion of a project, ‘ownership’, resulting from capacity building, might become an important tool of the management of such (agricultural) projects. It could lead to internal coherence and good relationships with donors (David Mosse in Cooke and Kothari, 2001, p. 30). This might happen after the project has been completed. However, projects need to go through a process of implementation through to delivery. The shaping of that process will, of necessity, require a dedicated input of donors and project staff. Tension between participatory processes and efficient implementation may make these ‘participatory processes’ during the implementation phase problematic if not impossible. If a project is well led, ongoing learning takes place by both the project staff and the rural people involved. If that occurs the sustainability of the project would be enhanced. This sustainability might be evident in the answers to questions such as
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development 191
Chapter 10 International, National and Local Agencies - Conclusion • are new approaches to technology being created?
• are new marketing possibilities being opened up?
• is the quality of soil and water conservation improving?
• is the effectiveness of seed inputs, seed distribution and storage satisfactory?
• are good links with national and international agencies involved in applied agricultural research being maintained? The answers to such questions may depend less on the autonomous and independent inputs by villagers than on the presence of an extension service, offering technology and affordable inputs (David Mosse in Cooke and Kothari, 2001, p.34). This does not mean that the idea of participation as a means of involvement and empowerment of participants through a people-centred orientation in development should be dismissed as ineffectual. Rather, one should recognize that the outcome of a participatory approach is unpredictable. In conjunction with asserting the benefit of people-centred development, a rigorous critical analysis of the impact of rural development programmes remains essential. As this has to do with sustainability, relevance and empowerment, it is open to failure. How can it be avoided that valid decision making processes are ignored? How can it be avoided that the dynamics of powerful groups produce participatory decisions which promote the interests of the powerful? In which cases can participation not provide a solution (Cooke and Kothari, 2001, p. 8)? In those cases where a participatory approach appears too prob-
lematic, one must be prepared to abandon, or not use a participatory approach to solve the problem. It is necessary to think about these problems with an open mind. In that context one difficulty would be to establish what the local needs are, without the expression of these necessitating being influenced by expectations of development. The participation of the local agricultural extension services and agricultural learning institutions might be valuable.
10.4 Conclusion 10.4.1 Global problems affecting food security 1.
Population pressure An important driver which emphasizes the urgent need to achieve an acceptable level of food security in a stable landscape, is the pressure resulting from the increasing world population. By 1950, a year of birth of many people alive today, the world population amounted to some 2.5 billion. By the year 2050, when many people born during the first decade of this century will still be alive, it may well amount to 9 billion. For every person alive in 1950 there may be some 3.5 people alive in 2050. By year 2150 this is projected to nearly 4 people (see Appendix 9, page 229 and Appendix 10, page 230). As shown in Appendix 9, by the year 1999, nearly 75% of the world population lived in Asia and Africa. There was an absolute increase of 2.2 and 1.7 times for the time span from 1970 to 2000 for Africa and Asia respectively. The pressure on food security arising out of this is self evident.
192 Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Conclusion 2.
Poverty Food security however cannot be achieved if the increase in the gap in wealth between rich and poor nations is not reduced to a more equitable level. The terms of trade (see page 187) are important in this respect. Some limited progress towards food security is being made (see ‘Down’ in Table 10.1 on page 189), and this can begin to alleviate poverty by reducing the pressure on basic needs (see Figure 4.3 on page 47).
3.
International trade This has been touched upon previously (see ‘Trade liberalization and market development’ on page 166; ‘Terms of trade’ on page 187). If small farmers in the WDRs are to be encouraged to increase their food production, something must be done to make the terms of trade more equitable.
4.
Consumption of resources If we continue using our global resources in the same way as at present (2010), by the early 2030s two planets would be needed to keep up with our demands. If modern western patterns of lifestyle were to be propagated into the developing world, as many as three planets Earth would be needed (see www.panda.org/livingplanet). As the level of available resources worldwide is limited on the globe with an increasing world population, it is clear that the consumption of resources must be sustainable (see Glossary). However, at its present level this consumption is not sustainable. Examples of this can be seen in the rate of deforestation (see Appendix 3, page 222). Global and regional leaf areas in forest biomes affect rainfall patterns and temperature. Rainfall
especially is important in that life cannot exist without adequate consumption of water. Deforestation seriously affects the ability of soils to retain nutrients. Erosion following deforestation brings about a loss of topsoil, irreplaceable, if not in the long term, certainly in the medium term. This can lead to desertification and a serious loss in production capacity of agricultural regions. 5. Loss of biodiversity Driven by population pressure, leading to increasing demands for food and water, energy and materials and the disposal of waste materials, natural habitat is changed through conversion for its employment as cultivated land, aquaculture and industrial or urban use. Ecosystems downstream of rivers, such as in delta plains, are changed by the building of dams for hydro-power, irrigation and flow regulation. Examples of this can be found for instance in the Zambezi delta as a result of the construction of the Cahora Bassa dam on the border between Zimbabwe and Mozambique. Over-harvesting of timber and wood for fuel has led to loss of forests and their plant and animal populations. The considerable flow of goods around the world has promoted the spread of invasive species from one part of the globe to another. They may compete for resources and cause the decline in native species populations. Pollution is another important cause of loss in biodiversity. Examples of this can be found in increasing use of nitrogen and phosphorus fertilizers in agriculture, causing excess nutrient loading producing eutrophication
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development 193
Chapter 10 International, National and Local Agencies - Conclusion and oxygen depletion. Toxic chemical pollution may arise from the use of pesticides in farming or aquaculture, or for that matter from industry or the mining of wastes. The increasing concentration of carbon dioxide in the atmosphere causes acidification of the oceans, affecting this all important carbon sink and adversely affecting shell and reef-building organisms. 6.
2.
Liaise with small farmers, their local representatives and regional authorities to set up experimental work to determine optimum multicropping practice.
3.
Ensure that this experimental work takes place in the framework of applied research. Farmer organizations and individual farmers who are prepared to set up pilot plots should be fully involved with this to the extent that they come to ‘own’ the procedures and process (see Figure 5.3 on page 81).
4.
Make world markets in primary agricultural products attractive for small farmers from the so-called lowincome countries. In this regard binding agreement should be reached on the subject of terms of trade at the conference referred to under point 1 above (see ‘Terms of trade’ on page 187).
5.
Determine the basic measures to be taken towards improving access to local and world markets (see ‘The physical infrastructure’ on page 187).
Climate change As shown by polar, montane, coastal and marine ecosystems, climate change has a global impact. As far as local areas are concerned, during the last few years (up to 2009) more extreme variations in temperature and rainfall appear to occur at shorter intervals during the last 20 years than as in earlier times (Houghton, 2009, pp. 70-79). Flooding in Bangladesh and Mozambique and prolonged droughts in parts of Sub-Saharan Africa are examples of this.
A thread running through this writing has been the effect of state factors (see Glossary) on all forms of life. Changing state factors affect phototrophs and chemotrophs. We, the human race, as chemotrophs, depend on energy produced by phototrophs, the effectiveness of which depends on climatic conditions. If these become adverse to the ability of phototrophs to produce this energy, all will be seriously affected, but people already living under marginal conditions, more so than others. Food security and landscape stability are important aspects of this ‘problem situation’ (see page 5). 10.4.2 Summary of main points 1.
specifically the feasibility of a coordinated and participatory approach to combat hunger and land degradation.
Hold a conference of international agencies, donor-nations and lowincome countries aiming to establish
Much civil engineering work at high financial cost would be needed to get this done ‘on the ground’. We have the technical ability to do this. A process to make the finance available could be set up and monitored through the offices of the United Nations. It will require political will and stability on all sides to undertake this over a number of years. 6.
Invest in education. This is essential if those farmers who remain in agriculture (necessary from the food security point of view) are to be equipped to
194 Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development
Conclusion manage the emerging knowledgebased farming systems. An important target is raising the efficiency of production methods in World Development Regions. The flow of information regarding farmers needs to be improved if knowledge-based commercial farming is to be successful. Support for services involved with new technologies and markets will be part of this. Effective communication between farmers (organizations), scientists and markets (organizations) will be essential for this. 10.4.3 Final paragraph We refer to Figure 7.2 (see page 131) and Figure 7.3 (see page 134). State factors (see Glossary) and associated ecosystem processes determine the potential of agricultural development. Furthermore the level of success and therefore the effectiveness of agricultural development programmes turns on participation by the local farming community. As regional inequalities are inevitable much detailed and careful work in the ‘finding out’ process (see Chapter 5) will have to be done. This requires community participation to determine the needs of the local population. These requirements form the basis for an ongoing process of coordinated planning by local rural communities and multiple agencies. In this overall environment, political and policy stability are essential and important prerequisites. These will be affected by the population densities, making this one of the most important factors affecting development. In this regard the need for much improved international development assistance working with the underdeveloped nations to achieve an acceptable level of education, health and infrastruc-
ture is pressing. It is vital that low-income countries be given the opportunity to make faster progress towards a better standard of living of their populations, if a dangerous imbalance in this new and now (2010) ever more interacting world is to be avoided. Coordinated effort, guided by international agencies with insight in these most important problems, can no longer be put on the back burner.
Planning The basic needs and requirements of the local population, based on their village and household planning, will have to be assessed with their participation. National and regional planning, guided by the availability of resources, should aim at determining policies which aim to meet the needs of village and household planning. The international donor community and finance institutions, such as the IMF, as well as national governments should place the core of their activities on supporting small-scale and subsistence farmers to achieve self sufficiency. The emphasis on high-value export crops and the development of non-agricultural activities, promoted by the World Bank and IMF under structural adjustment programmes, does not appear to produce the results required to achieve a reasonable level of food security (see Table 7.6 on page 130). The reasoning in this volume is that essential adevelopment should be guided by a bottom-up process, starting with, and based on, information supplied by the rural smallholding farming community. This is important especially in view of the considerable variations in soil fertility and stands of crops over short distances.
Food Security in Africa and Asia: Strategies for Small-scale Agricultural Development 195
Chapter 10 International, National and Local Agencies - Conclusion Top-down planning, as represented by national and regional planning, should aim at setting up policies which give space to bottom-up regional and local planning, aiming at improving agricultural smallholder production and productivity. Partnership with that smallholder community is essential as from this initial stage. Policies will be determined by the availability of resources. In that context the following seems relevant.
Subsidies Quite apart from plant growing techniques such as intercropping, the use of appropriate fertilizers and good quality seeds can be instrumental in a drive to improve productivity and production. The conflict between the need to keep urban consumer food prices reasonably low and to pay food-producing farmers at a level high enough to stimulate production, for instance by purchasing good quality seed material, gives rise to a potential revenue deficit for the farmer, which would need to be funded by government. This points to a delicate balance between food supply and demand.
With regard to credit, micro-finance, such as made available by the Grameen Foundation across four continents,1 can be helpful in providing the poor with a means to get out of poverty. Affordable prices for fertilizers and quality seeds can lead to a significant rise in yield [for an example see Africa Renewal (United Nations Department of Public Information) Vol. 22, No. 3 October 2008, page 3].
Consumer subsidies. These reduce or stabilize food prices. The aim would be to reduce poverty or maintain income among the urban poor. However, this could have a negative effect on food prices paid at the farm door, or alternatively such subsidies need to be financed by the state from taxation. Inefficient food markets could be the result. The drive should be towards increasing efficiency which does not appear to support the concept of consumer subsidies.
Finally It is hoped that the overall thrust laid down on these pages may be of some assistance to international and national agencies involved in this vitally important work of achieving food security.
Producer subsidies.
This represents cheap inputs for materials and equipment such as fertilizers, quality seeds and vegetative planting materials, irrigation pumps, or credit, or supported produce output prices. 1. http://www.grameenfoundation.org

Glossary Term
Definition and comment
Adaptation
The genetic adjustment by a population to maximize performance in a particular environment.
Adaptive management
This is management which involves experimentation in the design and implementation of policies, so subsequent management can be modified, based on learning from these experiments.
Agricultural population
This is defined as all persons depending for their livelihood on agriculture, hunting, fishing or forestry.
Agro-ecological zone
FAO delineates and defines these based on the average annual lengths of growing periods for crops. This depends on, among other things, rainfall and temperature. The lengths of growing periods for these AEZs have been set at for: humid greater than 270 days; moist to subhumid 180 to 269 days; dry sub-humid 120 to 179 days; semi-arid 60 to 119 days; arid 0 to 59 days.
Albedo
Fraction of the incident shortwave radiation reflected from a surface.
Annual and permanent crop land / cultivated area
Sum of land under temporary crops (double-cropped areas are counted once only), temporary meadows for mowing or pasture, land under market and kitchen gardens and land temporarily fallow (land abandoned for less than 5 years, or as a result of shifting cultivation, is not included), plus land cultivated with crops that occupy the land for long periods and do not need to be replanted after each harvest, such as cocoa, coffee and rubber (this category includes land under flowering shrubs, fruit trees, nut trees and vines, but excludes land under trees grown for wood or timber).
Climatic climax
End point of succession determined only by climate.
Climax
End point of succession where the structure and rates of ecosystem processes reach steady state and where resource consumption by vegetation is balanced by the rate of resource supply.
Civil society
The sphere in which social movement becomes organized (OU course T872, Part I, p. 43).
Economic externalities
In economics, an externality (or transaction spillover) is a cost or benefit, not transmitted through prices, incurred by a party who did not agree to the action causing the cost or benefit. A benefit in this case is called a positive externality or external benefit, while a cost is called a negative externality or external cost. (From Wikipedia.)

Ecosystem
Ecological system comprising all the organisms in an area and physical environment with which they interact (from Stuart Chapin III et al., 2002).
Ecosystem management
Application of ecological science to resource management to promote long-term sustainability of ecosystems and the delivery of essential ecosystem goods and services to society (from Stuart Chapin III et al., 2002).
Ecosystem processes
Inputs or losses of materials and energy to and from the ecosystem and the transfer of these substances among components of the system (from Stuart Chapin III et al., 2002).
Ecosystem resilience
The ability of an ecosystem to return rapidly to its original properties despite disturbance. Such ecosystems exhibit more stable and predictable ecosystem properties.
Endowment
Resources owned by a small-scale farmer, comprising land, labour power, physical and mental skills and physical well-being.
Entitlement
Direct entitlement - through owning and production of food; exchange entitlement - through selling of labour power (e.g. going to work for somebody else); trade entitlement, through the sale of commodities produced, enabling him, her to buy food (Sen, 1981).
Evapotranspiration
Water loss from an ecosystem by transpiration and surface evaporation.
Externalities
Long-term incidental consequences of an industrial or technological development.
Farm system
Comprises the family household, its resources and the resource flow and interactions at the individual farm level (from Hall et al., 2001).
Farming system
Comprises a population of individual farm systems, with generally similar resource bases, enterprise patterns, household livelihoods and constraints, for which similar development strategies and interventions would be appropriate (from Hall et al., 2001).
Feedback
Response in which the product of one of the final steps in a chain of events affects one of the first steps in this chain; fluctuations in rate or concentration are minimized with negative feedbacks or amplified with positive feedbacks.
GPP

Human development index (HDI)
This is a composite index measuring the average achievements in a country in three basic dimensions of human development: life expectancy at birth, knowledge as measured by the adult literacy rate and the combined gross enrolment for primary, secondary and tertiary schools; and the standard of living as measured in GDP per capita in purchasing power parity (PPP) US dollars (from Allen and Thomas, 2000, pp. 92, 288).
Impact
In the context of a project ‘impact’ refers to the effects of an intervention on its physical surroundings, the people involved, and/or organizational context (Guijt, 1998, p. 19).
Indicator
A quantitative or qualitative characteristic of a process or activity about which changes are to be measured.
Institutions
These can be seen as stable patterns of behaviour, recognized and valued by society. “Institutions whether organizations or not, are complexes of norms and behaviours that persist over time by serving collectively valued purposes. Institutions can be concrete like a nation’s central bank or quite diffuse and general such as the institution of money.” (Uphoff, 1996, emphasis in original. Quoted from OU course TU872.)
Interactive controls
Factors that control and respond to ecosystem characteristics, including resource supply, modulators, major functional types of organisms, disturbance regime and human activities (from Stuart Chapin III et al., 2002.)
Interactive participation
This is a type of participation in which “people participate in joint analysis, which leads to action plans and the formation of new local institutions or the strengthening of existing ones. Groups take over local decisions and so people have a stake in maintaining structures or practices.” (From PLA Notes 31, February 1998).
International poverty line / Dollar poverty
These are poverty reference lines set at US$1 and US$2 consumption per capita per day in 1993 PPP (purchasing power parity - the charge for an elementary food basket, converted on the basis of the exchange rate to US dollars in the countries concerned). The reference is used generally when discussing poverty, which, when set at this level, may be referred to as dollar poverty. Many countries also set national poverty lines, which, generally, differ from the international poverty line.
Land area
Total area of region within the farming system or region excluding areas under inland water bodies.
Land equivalent ratio
Expresses the total of intercropped yields (two or more crops produced at the same time) as a ratio of monocropped yield.

Landform
A single terrain feature.
Landscape
An assemblage of landforms.
Leaf area index
Leaf area per unit ground area. Projected LAI is the leaf area projected onto a horizontal plane. Total LAI is the total surface area of leaves, including the upper and lower surface of flat leaves and the cylindrical surface of conifer needles; it is approximately twice the value of projected LAI, except in the case of conifer needles, where the projected leaf area is multiplied by 3.1416, to get total leaf area.
Membership organization
People’s associations which undertake voluntary collective action and self help (Uphoff, 1995, p. 17).
Microfinance
Micro-finance, as practised by the Grameen Bank in Bangladesh, comprises the finding of substitutes for collateral, the latter being an asset, such as a piece of land, pledged by the borrower to provide security for a loan. Most lending is of this type. As poor people have few assets, this form of lending is not available to them. Mohammad Yunus (Bangladeshi university professor) and the North American NGO, ACCION, demonstrated that the problem could be met by lending to groups of poor people, rather than to individuals. Members of such a group, such as the Grameen Bank, would borrow finance to the extent they could manage to pay off on time, such as for instance $100 a year. Weekly instalments of $2 a week (plus interest), would be collected by a member of the bank’s staff in a public place in the home village of the borrowing group. Importantly, members of the group could have a further loan, only, if all group members were up to date with their repayments. This means that each member’s pressure on fellow members to repay loan instalments due on time, complements the pressure from the bank, thus acting as a substitute for collateral. In case of successful pressure leading to all repayments made on time, group members could qualify for another, larger loan (OU, TU 872, p. 63).
NPP
Net primary production. Quantity of new plant material produced annually (gross primary production minus plant respiration); includes new biomass, hydrocarbon emissions, root exudates and transfers to mycorrhizae.
Objective
An effectiveness standard which is as specific, as time bounded and as measurable as possible. Something towards which effort is devoted.
Performance indicator
A quantitative or qualitative characteristic of a process or activity about which changes are to be measured (Guijt, 1998, p. 17).

Rent seeking
In economics the meaning of the term ‘rent’ relevant in our context is a payment of gain deriving from a position of special privilege, additional to what would be expected in a competitive market. An example is ‘monopoly’, under which buyers or suppliers are able to act as ‘price makers’. Political influence can play a role (Bernstein et al., 1992). The roots of corruption are here: “regulators and their clients develop patterns of mutual accommodation which run against the public interest” (Wuyts et al., 1992).
Resilience
Rate at which a system returns to its reference state after a perturbation.
Resistance
Tendency of a system to remain in its reference state in the face of a disturbance.
Rhizosphere
Zone of soil that is directly influenced by roots.
Scale neutrality
A term referring to technologies that do not have marked economies of scale, that is becoming economically viable only at a certain scale of operation, that is on farms of a certain size. Scale-neutral technologies in agriculture are biochemical, like HYV seed packages, rather than mechanical, like tractors, combine harvesters and some types of irrigation.
Secondary succession
Succession that occurs on previously vegetated sites after a disturbance in which there are residual effects of organisms and organic matter from organisms present before the disturbance.
Sensible heat flux
Energy transferred between a surface and the near-surface atmosphere by conduction and movement to the bulk atmosphere by convection (Chapin III et al., 2002).
Small-scale and subsistence farmers
Small family farmers. What is distinctive about contemporary smallscale farmers with capitalism is that they are petty commodity producers subject to processes of class and other social differentiation, which can be charted through pressures on simple reproduction (middleincome small-scale farmers) on the one hand, and opportunities for accumulation on the other (‘rich’ small-scale farmers). Subsistence or poor small-scale farmers on the other hand are subject to a simple reproduction squeeze on their endowment (from Wilson, 1997).
Soil fertility
Ability of a soil to deliver the nutrients required for productive plant growth and carbon gain.

Soil horizon
Layers termed soil horizon develop within soil profiles. The characteristics of these horizons are used to classify soil pedons into soil series. The boundaries between soil horizons may be either sharp or gradual, but most of them are roughly parallel to the soil surface. The most common horizons are designated as A and B horizons. Others are called C or D horizons.
Soil profile
A vertical section of the soil, that exposes soil horizons.
Soil series
All areas that have soil profile characteristics falling within certain defined limits are classified together as a soil series. Theoretically, any two areas that combine the same type and degree of each of the five factors of soil formation will have the same soil series, whether the two areas occur near each other or on separate continents.
Stable landscape
A landscape accommodating population pressure, by meeting their needs for food and leisure, without sliding into degradation as a result of deforestation and desertification.
State factors
Independent variables that control the characteristics of soils and ecosystems: climate, parent material, topography. potential biota and time (Chapin III et al., 2002, p. 11).
Strategy
The pattern of activities followed by an organization in pursuit of its long term purposes.
Strategy issues
These can be characterized as developments inside or outside an organization that are likely to have an important impact on its ability to meet or determine its purposes or objectives.
Sustainable development
Development which meets the requirements of the present without compromising the ability of future generations to meet their own necessities.
Terms of trade
The relative prices of one group of commodities (generally those being sold) compared with those of another (generally those being bought). The terms of trade for a country is an index calculated by dividing the index of export prices by the index of import prices. The terms of trade deteriorate if import prices increase faster than export prices, or export prices fall faster than import prices. Similarly the terms of trade for primary products (compared with manufacturing products) deteriorate if the prices of primary products fall relative to those of manufactured products. (From Allen and Thomas, 2000, p. 294.)
