Los cambios acontecidos en la agricultura cubana a finales del siglo XX provocaron la ruptura del paradigma basado en la dependencia de importaciones, por lo que se precisó comenzar a construir un nuevo modelo técnico-económico sobre la base del desarrollo endógeno, asociado al fomento de capacidades innovadoras y de tecnologías sostenibles; ello exigió que los centros de desarrollo de conocimiento se centraran en la aplicación de innovaciones, mediante adecuados procesos de extensión rural.
La sécheresse qui sévit dans le Sahel depuis les années 1970 a fortement réduit les productions dans les principaux secteurs d’activités que sont la pêche, l’élevage et l’agriculture. Dans le Delta Intérieur du Niger au Mali (DIN), la pêche dont le développement est intimement lié aux fluctuations inter-saisonnières et interannuelles de la crue du fleuve Niger, est en crise. Les prises ont diminué de moitié, beaucoup de pêcheurs sont partis, certains ont adopté des pratiques non durables et les règles sociales subissent d’importantes modifications.
Natural resource management practices, such as the System of Rice Intensification (SRI), have been proposed to tackle agricultural challenges such as decreasing productivity growth and environmental degradation. Yet, the benefits of system technologies for farmers are often debated. Impacts seem to be context-specific, which is especially relevant in the small farm sector with its large degree of agroecological and socioeconomic heterogeneity. This was not always considered in previous research.
Since the early 1990s, liberalization of the seed market in Tanzania has attracted several foreign companies that now market maize hybrids in the country. In this article, we analyze the impacts of proprietary hybrids on maize yields, production, and household living standards. We build on a recent survey of smallholder maize farmers in two zones of Tanzania. Hybrid adoption rates are 48% and 13% in the North and East, respectively. Average net yield gains of hybrids are 50-60%, and there are also significant profit effects.
Ce manuel est destiné aux formateurs des organisations paysannes (OP) et à leurs membres en Afrique sub-saharienne. Le but étant de fournir une formation sur les techniques et opérations après-récolte afin d’améliorer la qualité des grains et ainsi de permettre l’augmentation des revenus et l’amélioration de la sécurité alimentaire des agriculteurs participants au programme. Dans le passé, les formations sur les opérations après-récolte n’ont pas été normalisées entre les différents pays membres du programme P4P.
In sub-Saharan Africa, there is increasing interest for the adaptation and use of the innovation systems approach to advance learning and development in the Agricultural Research and Development (ARD) sector. This crave is constrained by unavailability of a proven blue print that describe the paradigm shift from the linear approach and how such could function under different socio-economic, cultural and political climate.
Les conséquences sur les territoires des changements climatiques d’origine anthropique sont variables dans leurs expressions comme dans leurs effets, et les territoires sont inégaux face à ces variations climatiques en termes d’exposition aux effets (fonction de facteurs physiques, sociaux, économiques, culturels, politiques, etc.) comme en termes de capacité de réponse (capacité d’appréhension, d’anticipation, de réparation, etc.).
Intersectoral partnerships mirror the changing nature of the relationships among state, business and civil society organizations, and are often considered innovative mechanisms to overcome single actor failure in the context of globalization. This article analyzes the capacity of partnerships to promote sustainable change in global agrifood chains from a governance and a development perspective. The global coffee, cotton, and cocoa chains serve as main fields of application.
Based on international literature, preliminary experiences in a three-country West African research programme, and on the disappointing impact of agricultural research on African farm innovation, the current paper argues that institutional change demands rethinking the pathways to innovation so as to acknowledge the role of rules, distribution of power and wealth, interaction and positions. The time is opportune: climate change, food insecurity, high food prices and concomitant riots are turning national food production into a political issue also for African leaders.
This presentation argues the need of green growth in agriculture, analyzes features of the innovation systems and ends with some policies practices. The presentation has been prepared for "Innovation and Modernising the Rural Economy", OECD’s 8th Rural Development Policy Conference, 3-5 October 2012 (Krasnoyarsk, Russian Federation).
