Though extension services have long since proved their value to agricultural production and farmer prosperity, their record in sub-Saharan Africa has been mixed. To study the impact of such programs on farmers' learning about agricultural technologies, we implemented a quasi-randomized controlled trial and collected detailed panel data among Malawian farmers. Based on those findings, we develop a two-stage learning framework, in which farmers formulate yield expectations before deciding on how much effort to invest in learning about these processes. Using data centered on farmer beliefs, knowledge, and constraints, we find evidence that beliefs about potential yields hinge on first-hand and local experience, and that these beliefs significantly impact learning efforts. Consistent with this, we find that farmers who participated in season-long, farmer-led demonstration plot cultivation plan to adopt more components of new multi-component technology, compared to farmers who were invited to attend only field-day events.
C’est en 1954 que les paysans de la Commune rurale de l’Imanan, située dans l’Ouest du Niger, ont commencé la culture de pomme de terre. Partie d’une simple culture d’appoint associée à d’autres spéculations, la production de pomme de terre...
Farm input subsidies are often criticised on economic and ecological grounds. The promotion of natural resource management (NRM) technologies is widely seen as more sustainable to increase agricultural productivity and food security. Relatively little is known about how input subsidies...
De nombreux agriculteurs africains pratiquent des formes d'agriculture potentiellement qualifiables de "?biologiques?". Pourtant, la capacité de l'agriculture biologique à répondre aux enjeux de la sécurité alimentaire en Afrique est encore mal connue, car il existe peu de références expérimentales disponibles...
Le principal message qui est ressorti de la consultation est que l'agriculture familiale apportait une contribution cruciale aux secteurs agricole et halieutique et à la sécurité alimentaire de la région et, qu'à ce titre, les mesures de soutien de cette...
This book highlights the important links between agriculture and nutrition, both direct and indirect, both theoretical and practical. It explores these relationships through various frameworks, such as value chains, programmes and policies, as well as through diverse perspectives, such as...
