Este artículo analiza algunos conceptos sobre el desarrollo de cadenas de valor como un tipo de intervención que promueve el crecimiento agrícola y apunta a mejorar los ingresos de los productores mediante el fortalecimiento de los vínculos entre las empresas y los pequeños productores.
This chapter documents the learning process within the framework of innovation of soil fertility management practices that emerged from the implementation of Participatory Extension Approach (PEA) as part of service delivery reorientation within the Limpopo Department of Agriculture in South Africa.The chapter gives a narrative description of what transpired during the interaction between researchers, extension officers and farmers, the processes involved, the lessons and the conclusion.
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.
Research, extension, and advisory services are some of the most knowledge-intensive elements of agricultural innovation systems. They are also among the heaviest users of information communication technologies (ICTs). This module introduces ICT developments in the wider innovation and knowledge systems as well as explores drivers of ICT use in research and extension
This is a chapter of the book Innovation Platforms for Agricultural Development edited by Iddo Dror, Jean-Joseph Cadilhon, Marc Schut, Michael Misiko and Shreya Maheshwari.
Market opportunities are increasing at a rapid pace for livestock products, fuelled by rising incomes, globalisation and urbanisation, particularly in the developing world. At the same time, these opportunities bring increased complexity in the supply channels that market, distribute, organise and govern high-value products. This begs the questions on the ability of smallholder producers to contribute to this complex process.
In the Amazon, slash and burn is the most common technique used by American-Indians, small farmers and even big ranches to transform forests into rural landscapes. The basis of food subsistence for diverse populations (rice, corn and bean), slash and burn is also a must for the plantation of cocoa, coffee, palms and pastures. The Amazonian rural landscape is currently dominated by pastures, occupying around 80 % of the deforested surface.
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.
Pour répondre à la montée en puissance des enjeux environnementaux, le monde agricole met en œuvre des dispositifs agri-environnementaux (AE) à destination des agriculteurs afin d’en orienter les pratiques.
Le Touat-Gourara-Tidikelt est un très vaste espace, qui occupe près du quart la superficie du Sahara algérien. Il fait partie intégrante de la zone la plus aride du monde, aux contraintes naturelles particulièrement difficiles. Cet espace connu comme le « Pays des foggaras » était savamment exploité, depuis plus d’un millénaire, par les oasiens qui profitaient de la dynamique économique impulsée par le commerce transsaharien.
