    Afrique occidentale, Afrique sub-saharienne, Afrique, Ghana

    "An economywide, multimarket model is constructed for Ghana and the effects of agricultural soil erosion on crop yields are explicitly modeled at the subnational regional level for eight main staple crops. The model is used to evaluate the aggregate economic costs of soil erosion by taking into account economywide linkages between production and consumption, across sectors and agricultural subsectors... Sustainable land management (SLM) is the key to reducing agricultural soil loss.

    This article investigates the effects of wheat genetic diversity and land degradation on risk and agricultural productivity in less favored production environments of a developing agricultural economy. Drawing production data from a household survey conducted in the highlands of Ethiopia, we estimate a stochastic production function to evaluate the effects of variety richness, land degradation, and their interaction on the mean and the variance of wheat yield. Ethiopia is a center of diversity for durum wheat and farmers manage complex variety mixtures on multiple plots.

    Asia du sud-est, Asie, Indonésie

    The paper draws on findings from research in South Sulawesi and Jambi Provinces, Indonesia, looking at the role of collective action in helping two local community groups enhance their bargaining power vis a vis other market players (such as collectors, small- and large-scale industries) and promote an increased demand for non-timber forest products. The first group has traditionally collected rattan (Calamus sp) from surrounding forests and was struggling to sell their products at a better price amid market uncertainties and the lack of supportive government policies.

    Afrique orientale, Kenya

    Over the last two decades, several seed-related programs have been initiated in eastern Kenya to improve farmers’ access to quality seeds of dryland cereals and legumes. They are provided during two occasions, regular and emergency times. But very often, the formal supply mechanisms limit their role in provision of seeds other than maize. In the absence of any formalized systems of seed provision for other dryland crops, such as sorghum and pigeon pea, farmers have preferred local markets for their seed needs, especially during distress periods.

    This article addresses the methodological complexities inherent in researching poverty, examining how to differentiate the poor from other social groups, and how to assess the relationships between poverty and technology adoption and impact. The use of specific types of quantitative and qualitative methods, the degree to which their integration was achieved, and the benefits of integration are analyzed.

    Contract farming may be defined as agricultural production carried out according to a prior agreement in which the farmer commits to producing a given product in a given manner and the buyer commits to purchasing it. Often, the buyer provides the farmer with technical assistance, seeds, fertilizer, and other inputs on credit and offers a guaranteed price for the output. Proponents of contract farming argue that it links small-scale farmers to lucrative markets and solves a number of problems small-scale farmers face in diversifying into high-value commodities.

    The study relates village seed systems to biological diversity of millet crops grown by farmers in the semi-arid lands of Andhra Pradesh and Karnataka, India. In these subsistence-oriented, semi-arid production systems the environment is marginal for crop growth and often there is no substitute for millet crops. Across communities, farmers grow 13 different combinations of pearl millet, sorghum, finger millet, little millet, and foxtail millet varieties, but individual farmers grow an average of only 2–3 millet varieties per season.
