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.
Les notions de services environnementaux et de services écosystémiques (SE) ont connu un rapide engouement au cours de la dernière décennie et sont à l’origine de nouveaux instruments pour faire face à divers problèmes environnementaux, notamment la déforestation : les dispositifs de Paiements pour Services Environnementaux (PSE). Néanmoins, l’intégration du concept dans les politiques publiques reste un processus rare.
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 purpose of this paper is to summarize the challenges and the practical successes that a selected number of countries are experiencing in moving towards 'climate-smart' agriculture while also meeting the food requirements of a growing population, broader economic development and green growth objectives. It complements papers prepared in 2010 on technologies and policy instruments, research, and farmers' perspectives.
This report presents an update on the economic challenges facing Ethiopia with a focus on the shared goal of accelerating equitable growth. The starting point is the Government's own Plan for Accelerated and Sustained Development to End Poverty (PASDEP), which is in the process of finalization, and is designed to cover the period 2005-2010.

This report, drawing on a rapid desk-based review, seeks to outline the potential role of Afican Advisory Services (AAS) in addressing climate change and explores how far AAS in sub-Saharan Africa (SSA) are able to respond to climatic and other pressures. Recommendations are outlined, indicating how AFAAS can help AAS to understand climate change better and become more ‘adaptive’ in their responses
The publication reviews forty years of development experience and concludes that donors and partner countries alike have tended to look at capacity development as mainly a technical process, or as a transfer of knowledge or institutions from North to South.
This paper examines the role of postsecondary agricultural education and training (AET) in sub-Saharan Africa in the context of the region’s agricultural innovation systems. Specifically, the paper looks at how AET in sub-Saharan Africa can contribute to agricultural development by strengthening innovative capacity, or the ability of individuals and organisations to introduce new products and processes that are socially or economically relevant, particularly with respect to smallholder farmers who represent the largest group of agricultural producers in the region.
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.
