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 this Africa has to define agriculture as a force in economic growth by: advancing scientific and technological research; investing in infrastructure; fostering higher technical training; and creating regional markets.
Les populations rurales sédentaires de la commune de Hombori (Mali) pratiquent presque toutes la culture de mil associée au petit élevage non transhumant. Au-delà des contraintes environnementales d’une région semi-aride, le maintien de l’agro-élevage repose sur une double maitrise, des territoires et des ressources, l’une et l’autre ne pouvant se confondre.
Le sud du Brésil qui possède un bon potentiel naturel en raison de son climat chaud et humide et de son relief favorable est voué principalement à l’élevage et aux cultures de soja, de riz et de maïs. Cette région, comme d’autres au Brésil, participe à la production de denrées agricoles pour le marché national et international. Elle est ainsi soumise à l’intensification des pratiques dont les impacts sur l’environnement sont notoires. L’étude concerne plus particulièrement le bassin versant de l’Ibicuí (46 800 km²), situé dans le sud-ouest de l’État de Rio Grande do Sul.
L’agriculture de conservation (AC) obéit à trois principes : travail du sol minimal, couverture du sol permanente et multiculture. Partant de ses avantages avérés pour l’écologie du sol, la séquestration de carbone et son adoption massive dans quelques régions du monde, elle est présentée par ses promoteurs comme un système durable convenant à tous contextes. Dès lors elle a été mondialement diffusée au nom du développement durable.
Les conventions locales peuvent être définies comme des accords légitimes négociés entre plusieurs parties prenantes (stakeholders) dans une perspective de régulation des ressources naturelles – en termes de contrôle, d’accès, d’appropriation, d’usage et d’exploitation – et de l’environnement. Au Sahel, bien qu’elles soient en vogue et jouissent davantage d’attention chez les décideurs, elles constituent des instruments encore peu exploités dans le contexte actuel de la décentralisation (Diallo, 2003).
Innovation platforms (IPs) form a popular vehicle in agricultural research for development (AR4D) to facilitate stakeholder interaction, agenda setting, and collective action toward sustainable agricultural development. In this article, the authors analyze multilevel stakeholder engagement in fulfilling seven key innovation system functions. Data are gathered from experiences with interlinked community and (sub)national IPs established under a global AR4D program aimed at stimulating sustainable agricultural development in Central Africa.
The relationship between motivation and participation in five agricultural research and development innovation platforms (IPs) in Africa’s Great Lakes Region is examined. We analyze data from surveys and in-depth interviews, and focus group discussions. Although farmers prioritized new knowledge and skills, these were not sufficient to consistently foster active participation. Anticipated economic (markets, income, and credit) and material (agricultural inputs) livelihood benefits did encourage active farmer participation.
This study analyse how agricultural extension can be made more effective in terms of increasing farmers’ adoption of pro-nutrition technologies, such as biofortified crops. In a randomised controlled trial with farmers in Kenya, the authors implemented several extension treatments and evaluated their effects on the adoption of beans biofortified with iron and zinc. Difference-in-difference estimates show that intensive agricultural training can increase technology adoption considerably.
Agricultural innovation is a process that takes a multitude of different forms, and, within this process, agricultural research and expertise are mobilised at different points in time for different purposes. This paper uses two key analytical principles to establish how research is actually put into use. The first, which concerns the configurations of organisations and their relationships associated with innovation, reveals the additional set of resources and expertise that research needs to be married to, and sheds light on the types of arrangements that allow this marriage to take place.
International centres of excellence (ICE) in which foreign research organizations are attracted to developing and emerging countries via dedicated funding schemes to support technological catching-up and strengthening of innovation systems, can have benefits for both host countries and their international research partners through knowledge spill-overs and business opportunities.
