Agricultural education, research, and extension can contribute substantially to reducing rural poverty in the developing world. However, evidence suggests that their contributions are falling short in Sub-Saharan Africa. The entry of new actors, technologies, and market forces, when combined with new economic and demographic pressures, suggests the need for more innovative and less linear approaches to promoting a technological transformation of smallholder agriculture. This paper explores methodologies that can help improve the study of agricultural innovation processes and their role in transforming agriculture. We examine methods that address three key issues: (a) how agents interact in the production, exchange, and use of knowledge and information; (b) how agents respond individually and collectively to technological, institutional, or organizational opportunities and constraints; and (c) how policy changes can enhance the welfare effects of these interactions and responses. Methods include social network analysis, innovation histories, cross-country comparisons, and game-theory modeling.
African agriculture is currently at a crossroads, at which persistent food shortages are compounded by threats from climate change. But, as this book argues, Africa can feed itself in a generation and help contribute to global food security. To achieve...
The purpose of this paper is to map some elements that can contribute to an IFAD strategy to stimulate and support pro-poor innovations. It is an initial or exploratory document that hopefully will add to an ongoing and necessary debate,...

L’ouest du Rio Grande do Sul est dominé par la culture du soja, du riz et par l’élevage bovin. Dans la partie sableuse, le milieu est affecté par des phénomènes d’érosion produisant des modelés éoliens spectaculaires (arenização) rappelant dans l’imaginaire...
Despite efforts over recent years to improve the status of agriculture in sub-Saharan Africa, little change has been noted, due partially to the fact that efforts have come from individual entities, which had short-term funding or lacked the necessary expertise...
