Africa RISING (AR) is a research-for-development program that aims to create opportunities for smallholder farmers to move out of hunger and poverty through sustainable intensification of their farming systems.
In recent years, the notion of doing research with multiple partners has become an important concept in international development. This reflects the belief that partnerships are important for solving complex problems, reducing costs and competition for the same resources, increasing efficiency and ownership, and ensuring greater accountability.
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.
Aujourd’hui encore, les forêts restent un enjeu vital. Ceci alors que le développement accéléré de beaucoup de régions provoque une pression croissante sur les écosystèmes forestiers. Parc Yasuni en Equateur, parc national des Virunga en RDC, ou plus largement forêts tropicales au Brésil ou en Indonésie, on peut multiplier les exemples de conflits socio-environnementaux où la question de l’utilisation et de la propriété des ressources forestières est l’objet de luttes féroces entre populations indigènes, ONG environnementales, multinationales et gouvernements, etc.
The increasing demand for agricultural commodities is a major cause of tropical deforestation. However, pressure is increasing for greater sustainability of commodity value chains. This includes the demand to establish new crop plantations and pasture areas on already deforested land so that new forest clearing for agriculture is minimized. Where tree crops are planted as part of agroforestry systems on deforested land, this amounts to a form of re-agro-forestation which can generate environmental benefits in addition to crop production.
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.
Agroforestry (AF) systems have been the focus of numerous research and development projects in southern Africa, yet their adoption rate generally remains low. Employing on-farm, participatory research techniques in southern Malawi, was compared the suitability of three AF-based systems that relay crop the dominant staple, maize (Zea mays), with the perennial legumes Sesbania sesban, Tephrosia vogelii, and Cajanus cajan (pigeonpea).
This paper aims at analysing the competitive performance of a very tradeable global commodity and the main export crop of Cameroon from 1961 to 2013 through the application of a step-wise analytical framework accommodating aspects of agri-value chain analysis. This conventional analysis was expanded to include value chain comparisons between various valueadding processes in the Cameroonian cocoa value chain as well as consensus vs.
The merger of Dow and DuPont, the acquisition of Syngenta by Chem- China, and the acquisition of Monsanto by Bayer have recently reshaped the global seed and biotech industry and caused concern about growing mar- ket concentration. This review documents market concentration in seed and agricultural biotech markets and discusses its causes and impacts. The avail- able evidence suggests that concentration in seed markets varies strongly by crop and by country, while markets for biotech traits are considerably more concentrated.
En este artículo se procura identificar, describir y comparar la concepción de extensión rural que guía a nivel subjetivo las prácticas de extensión de técnicos que trabajan en diez diferentes países latinoamericanos, para luego comparar estas concepciones con los modelos y lineamientos de extensión propuestos por la bibliografía. Para esto, primero se describen distintas concepciones de extensión que han tenido importancia en América Latina a lo largo de la historia, luego se presenta la metodología de investigación utilizada, presentándose por último los resultados a los que arribó
