In the Office du Niger large rice farming irrigation scheme in Mali, water management has been a permanent source of tension between the smallholder tenants and the administration. The transfer of tertiary canal maintenance to the tenant farmers was expected to improve water management but, in practice, that rather led to deterioration.
There is an emerging body of literature analyzing how smallholder farmers in developing countries can benefit from modern supply chains. However, most of the available studies concentrate on export markets and fail to capture spillover effects that modern supply chains may have onlocal markets. Here, we analyze the case of sweet pepper in Thailand, which was initially introduced as a product innovation in modern supplychains, but which is now widely traded also in more traditional markets.
This article adds to the literature about the impact of social networks on the adoption of modern seed technologies among smallholder farmers in developing countries. The analysis centers on the adoption of hybrid wheat and hybrid pearl millet in India. In the local context, both crops are cultivated mainly on a subsistence basis, and they provide examples of hybrid technologies at very different diffusion stages: while hybrid wheat was commercialized in India only in 2001, hybrid pearl millet was launched in 1965.
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 affect farmers’ decisions to adopt NRM technologies. There are concerns of incompatibility, because NRM technologies are one strategy to reduce the use of external inputs in intensive production systems.
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.
We analyse the impact of intensity of tillage on wheat productivity and risk exposure using panel household-plot level data from Ethiopia. In order to control for selection bias, we estimate a flexible moment-based production function using an endogenous switching regression treatment effects model. We find that tillage has a complementary impact on productivity and risk exposure. As the intensity of tillage increases, productivity increases and farmers’ exposure to risk declines. Our results suggest that smallholder farmers use tillage as an ex-ante risk management strategy.
This book is the re-titled third edition of the widely used Agricultural Extension (van den Ban & Hawkins, 1988, 1996). Building on the previous editions,Communication for Rural Innovation maintains and adapts the insights and conceptual models of value today, while reflecting many new ideas, angles and modes of thinking concerning how agricultural extension is taught and carried through today.
Lors de l'intervention d'une plate-forme d'innovation (groupe d'acteurs concernés) dans un domaine donné, nous avons tendance à attribuer les causes du changement aux actions de cette plate-forme. Cet article utilise le cas d'une plate-forme d'innovation dans le secteur du karité au Mali pour analyser comment les plates-formes d'innovation produisent les résultats escomptés.
Confrontés aux évolutions des enjeux et modèles de développement touchant les secteurs de l’agriculture et de l’alimentation, les organismes de recherche interrogent les méthodes d’évaluation des impacts liées aux activités de recherche. En effet les cadres méthodologiques conventionnels utilisés depuis les années 1950 ne répondent plus aux attentes sociétales et aux réalités de l’activité de recherche dans ce domaine.
La concertation semble en passe de devenir une norme en matière de gestion des ressources naturelles et de l'environnement. Pourtant, son impact reste difficile à caractériser, ce qui génère une forme de désenchantement auprès de ses promoteurs. Au cours d'un projet de recherche concertée à La Réunion, nous avons cherché à mieux comprendre comment la concertation influence l'écologie territoriale.
