Seed is the starting point of plant life, and hence the most fundamental input of agriculture. A seed system that assures the availability of the desired quality of seed to the producer at the right time is indispensable for his farming enterprise. In the case of the potato crop, the seed most commonly used is strictly speaking no seed, but a tuber. The constraints and opportunities in seed potato systems in East Africa are of a combined social, economic and technical nature.
Integrated soil fertility management (ISFM) has been promoted by research and philanthropic organizations as well as governments in an attempt to increase crop yields and improve livelihoods of smallholder farmers in Africa. As this has largely been a continent-wide initiative, it is surprising that there is still scant information on its impact on crop yields and household income. This paper uses a counterfactual model to assess ISFM impact on yields and total household incomes using farm household data from Tamale (northern Ghana) and Kakamega (western Kenya).
Agriculture is central to Ethiopian economy but its sustainable development faces enormous challenges. Low innovation capacity, low productivity, dwindling natural resources and climate change, small-scale subsistence farming, and low levels of market integration and value addition have all made agricultural development more complex. In spite of the decades of research and development efforts, the rate of growth for both crop and livestock productivity has remained low.
The citizens of Lesotho rely on a complex web of livelihood strategies made primarily of family kinships and strong community networks. Recently, community breakdowns have occurred because of extensive land degradation, soil erosion, widespread poverty, and HIV/AIDs. This thesis focuses on two aspects which are likely to help decrease the problems earlier stated.
Les mutations du secteur agricole bamiléké (Ouest-Cameroun) ont été très importantes depuis le milieu des années 80, marqué par la chute des prix du café, alors principale production du pays Bamiléké, et par la crise économique au Cameroun. Dans cette thèse, le concept de dispositif (Foucault, Moisdon, Maugeri, RIDT-INRA) est l'outil principal d'analyse de ce secteur agricole.

El presente trabajo se propuso elaborar participativamente una propuesta de estrategia trinacional para la incidencia política en el sector agropecuario a partir del enfoque de Agricultura Climaticamente Inteligente. Para lograr lo anterior, se realizó un análisis de los actores territoriales vinculados con el sector agropecuario con el propósito de visualizar las oportunidades y potencialidades para emprender un proceso de incidencia política en el territorio, a partir de la construcción participativa de una propuesta de estrategia.
Este trabajo se planteó como objetivo contribuir al diseño de políticas públicas para favorecer la innovación del cultivo de maíz en la región Caribe colombiana mediante el enfoque de sistemas específicos de innovación.
The transition to a market for agricultural research and knowledge-intensive services presents various challenges for actors in the agricultural knowledge infrastructure, on both the demand side (end users of innovations such as farmers, and the government) and the supply side (providers of research and knowledge-intensive services). New organizational arrangements try to bring together supply and demand in the agricultural knowledge infrastructure. This thesis is about such new organizational arrangements
Innovation processes in rural contexts occur in systems that are diverse, coupled with complex challenges. Dealing with complex systems requires an understanding of the social dynamics of actor networks and innovation.This study attempted to provide insights on thecompositional dynamics of actor networks,and how they influenceinteractive learning and innovation among agro-processing enterprises in South Africa. The guiding research questions to help address the study objectives are:What are the structural characteristics of actor networks for innovation in rural contexts?
