"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.

...There are many good books and resources on sustainable agriculture and
we have learnt much from them. However refugees are constrained in their
agricultural practices due to limited access to land, water and other resources.
This Handbook attempts to present a summary of simple adaptations of ideas
found in other books, manuals and resources on sustainable agriculture.
This Handbook is not a textbook as such, but a compilation of different
subjects for people to pick and choose. We know that it is not complete and

This Handbook is designed for both farmers and students to use in the field and during training. It is divided into eight sections, each one containing several topics and all illustrated with large clear pictures. The Handbook can be read from beginning to end or each topic can be read separately. Space is provided for readers to take notes and to add their own local knowledge...Our people have always been farmers. Farmers of the river lands, of the mountains, and of the forests.

Land is the most fundamental resource in any society because it is the basis of human survival. Land is the space upon which all human activities take place and provides continued existence of all life forms and minerals.
