Este artículo proporciona una descripción de la fase upstream de la cadena agroindustrial de la palma de aceite. El trabajo caracteriza la funcionalidad y relaciones de eslabones y escalones de la cadena de abastecimiento y de valor de la cadena en Colombia. El trabajo representa un esfuerzo pionero que busca contribuir a mejorar la eficiencia y eficacia del sector palmero colombiano
En este estudio se realizó una investigación cuantitativa descriptiva de carácter transversal que permitió reconstruir el perfil de los extensionistas rurales que trabajan en el sistema de extensión público argentino. Para este fin se realizó una encuesta (enviada vía email) a extensionistas del INTA, ProHuerta y de la Subsecretaría de Agricultura Familiar. Para el análisis de los datos se utilizó el software SPSS 17.0.
A decline in public sector extension services in developing countries has led to an increasing emphasis on alternative extension approaches that are participatory, demand-driven, client-oriented, and farmer centered. One such approach is the volunteer farmer-trainer (VFT) approach, a form of farmer-to-farmer extension where VFTs host demonstration plots and share information on improved agricultural practices within their community. VFTs are trained by extension staff and they in turn train other farmers.
The authors surveyed small-scale farmers in the Kenyan Rift Valley province (Narok and Nakuru districts) to describe constraints to, and changes in, livestock production and to assess the extent to which farmers have adopted new technologies promoted by extension services. In the arid areas of southern Narok, farmer's main constraints were drought and disease. Farmers in Nakuru district, situated in the fertile highlands of the Rift Valley, were also affected by disease but also lacked markets and capital.
Este estudio analizó la evolución de una red de innovación entre productores de hule natural durante tres periodos de observación (dos olas o tres años), y evaluó cómo los productores reaccionan a diferentes innovaciones en un momento dado. Las prácticas de innovación fueron agrupadas en tres actividades: control de plagas y enfermedades, establecimiento y manejo de plantaciones, y manejo de cosecha y poscosecha.
Innovations in the agri-food sector are needed to create a sustainable food supply. Sustainable food supply requires unexpectedly that densely populated regions remain food producers. A Dutch innovation program has aimed at showing the way forward through creating a number of practice and scientific projects. Generic lessons from the scientific projects in this program are likely to be of interest to agricultural innovation in other densely populated regions in the world.
This paper briefly analyse the genesis, development and change in public sector-led extension approaches in India showing its temporal pattern, emerging innovations in extension approaches and the way forward. It discusses decentralized, community based, pluralistic extension approaches and their opportunities as well as limitations in changing agricultural and natural resources scenario.
This article starts by describing the evolution of innovation in agricultural research and cooperation for development, including an historical overview of agricultural research for development from green revolution to the re-discover of traditional knowledge. Then the authors analyze participation in innovation processes and make a comparison of innovation systems and platforms targeting the agri-food sector in developing countries. A particular focus is reserved to the European regional networks and to the experience of the USAID Middle East Water and Livelihoods Initiative.
Les politiques publiques en faveur du développement rural se matérialisent au travers d’instruments incitatifs, de règlements particuliers, ou encore par l’accompagnement des initiatives particulières. Ceux-ci répondent en général à la mise en place d’une stratégie nationale d’appui à une filière agricole. Dans le cas du quinoa cultivé au Chili, chaque région de production observe un développement propre.
Cet article revient sur l’activisme des multinationales de l’agrofourniture et de l’agroalimentaire dans la gouvernance du secteur agricole. Pour ce faire nous nous appuyons sur deux cas de figure qui ont trait à la conception et à la diffusion d’innovations à l’échelle internationale : la technique du semis direct, et la mise en place de systèmes de certification « durable » des principales matières premières agricoles.
