"For the practice of agroforestry to yield its full potential, it needs to bring health and nutrition to the fore.

Malaria, schistosomiasis (bilharzia), and Japanese encephalitis are the major vector-borne diseases whose increase or decrease can be attributed to agricultural water development (see table). Others include dengue fever, yellow fever, and filariasis. Young children in poor communities are particularly affected: malaria is among the top five causes of death among under-fives in Sub-Saharan Africa; schistosomiasis among children affects growth, nutritional status, and cognitive development; and encephalitis occurs mainly in young children...

Beyond the obvious catastrophic effects of the HIV/AIDS pandemic on mortality, demographicchanges, and the suffering of individuals and their families, we are still only learning about thecomplex longer-term effects of the pandemic on poverty and vulnerability. For example, theHIV/AIDS pandemic has substantially increased the number of widow-headed households inAfrica. A huge number of conceptual and qualitative studies highlight gender inequalities inproperty rights, and the difficulties that widows and their dependents face in retaining access toland after the death of their husbands.

Agriculture is fundamental to achieving nutrition goals: it produces the food, energy, and nutrients essential for human health and well-being. Gains in food production have played a key role in feeding growing and malnourished populations. Yet they have not translated into a hunger-free world nor prevented the development of further nutritional challenges. Micronutrient deficiencies (for example, of vitamin A, iron, iodine, and zinc) are now recognized as being even more limiting for human growth, development, health, and productivity than energy deficits.

"With half the world’s population living in cities and towns, many poor urban dwellers face problems gaining access to adequate supplies of nutritionally balanced food. For many urban populations, an important source of food is urban and peri-urban agriculture (UPA). Production and processing of crops—particularly horticultural crops—and livestock is frequently part of urban and peri-urban livelihood strategies, and the food produced forms a large part of informal sector economic activity.

"Agricultural production relies on environmental services to transform raw inputs into the nutritious and diverse food that humans rely on for survival. Although the practice of agriculture is essential for human health, careless and inappropriate agricultural practices can degrade and contaminate natural resources and in so doing, harm human health. Modified agricultural practices can help mitigate these problems.

"Agriculture is the main source of livelihood of the majority of people affected by HIV and AIDS globally, and it is being progressively undermined by the disease. In Sub-Saharan Africa AIDS is affecting the rural landscape in ways that demand a rethinking of development policy and practice, and parts of South Asia may soon face a similar situation.... There is clearly tremendous scope for agricultural policy to become more HIV-responsive, both to further AIDS-related objectives and to help achieve agricultural objectives. Yet there are no magic bullets.

Ethnic minorities in the mountainous forest regions of northern Thailand and northern Vietnam live in a particularly restrictive political, social and economic environment. Widespread degradation of land, water and forest resources has adverse effects on the livelihoods of these groups. Given the dramatically increasing scarcity of natural resources, regulation of resource access and allocation are becoming fundamental for the development of sustainable resource management, in which an active participation of the local population in planning and implementation is a crucial prerequisite.

Empirical investigation of the impact of institutional and socioeconomic factors on agricultural productivity and natural resource conditions is important for an informed evaluation of current policies, and to identify areas for future improvements. In this line, the current study addresses three topics of relevance to the process of agricultural intensification and natural resource management in the context of the less-favoured Highlands of Tigray, Ethiopia.

Population pressures and the need to optimize the use of limited available land has led to increasing cropping affluence levels within the maize agro-ecologies in Kenya, and a shift from large to smallholder intensification and multiple cropping patterns. Using a geographic information system, this study relates cropping patterns, by area share, maize productivity and household incomes across maize agro-ecologies, with the purpose to establish a decision support system for optimizing land allocation and in priority setting for introduction of new technologies such as Bt maize varieties.

This paper represents part of an area of work which analyses access to natural resources in Mozambique. An initial paper examined the extent to which Mozambique’s recent regulatory changes to natural resource access and management have had their intended effects (LSP Working Paper 17: Norfolk, S. (2004). “Examining access to natural resources and linkages to sustainable livelihoods: a case study of Mozambique”). This paper is complemented by LSP Working Paper 28: Tanner et al. (2006).

About 88% of the population is concentrated in the highlands, which constitute less than half of the national territory; here the population density is 141 persons km-2. Agriculture is the main source of livelihood and national income in the country. Over 85% of the population directly depends on it and about half of the GDP is generated from the sector. However, agriculture is small-scale and subsistence oriented, and it is in a very low state of development.
