    Namibie, Afrique sub-saharienne

    Results from this study show that the over-used but under-researched association between grazing and land degradation in the Kalahari has been oversimplified. In typical Kalahari conditions, the ecological changes that have been brought about by grazing cannot be linked with more fundamental changes in ecosystem function. Basic soil processes appear relatively unaffected by grazing pressure outside the sacrifice zone, and there is no evidence to suggest that the resilience of the system has been affected through soil degradation.

    This paper focuses on extracts from a recent comparative analysis of livestock and land use surveys across a range of agro-climatic conditions in sub-Saharan Africa, based on information from systematic low level aerial reconnaissance and complementary ground studies in Mali, Niger, Nigeria, Sudan and Tchad, between 1980 and 1993.

    Commercial farms in South Africa could become significantly more efficient if they became smaller.

    Zimbabwe, Afrique sub-saharienne

    This case study of Zimbabwe has examined developments in biotechnology against the background of a well-developed national agricultural research, plant breeding and seeds system. It has then assessed the constraints to biotechnology research, technology development and diffusion in the light of the resources available and the technology transfer mechanisms in place for different groups of farmers.

    In urban areas of Cote d'Ivoire, human capital is the endowment that best explains welfare changes over time. In rural areas, physical capital especially the amount of land and farm equipment owned matters most.Empirical investigations of poverty in developing countries tend to focus on the incidence of poverty at a particular point in time. If the incidence of poverty increases, however, there is no information about how many new poor have joined the existing poor and how many people have escaped poverty.Yet this distinction is of crucial policy importance.

    Burkina Faso, Afrique sub-saharienne

    Building soil conservation practices on a base of indigenous knowledge greatly increases the rate at which they are adopted by farmers in Burkina Faso. Indigenous soil conservation practices are ecologically sound and need to be taken into account when efforts are made to introduce modern agricultural techniques. This article provides an example of how soil conservation practices built upon local systems for conserving resources were preferred by small-scale farmers over newly introduced conservation techniques.
