El objeto de esta investigación es aproximarse a una construcción teórica que permita entender la asimilación del conocimiento popular desde la función de extensión universitaria, ofreciendo la posibilidad de rescatar su valor como forma válida del saber. Para ello, se exploró la evolución de la extensión universitaria y del conocimiento popular, desde una perspectiva real, procediéndose seguidamente a identificar los elementos presentes y sus respectivas relaciones de interdependencia, en un plano teórico.
The study assesses the farmers’ use of Global System for Mobile (GSM) for communication among farmers in agricultural extension programs in Taraba State, Nigeria. Specifically, the objectives include: identify key areas in which GSM are used for communication in agricultural extension programs activities, determine the frequency of usage of GSM for information exchange between farmers and extension personnel; and ascertain farmers’ satisfaction in the use of GSM in obtaining information in the various agricultural extension programs.
Familiar mixed dairy sheep farm is the most widespread system in the Mediterranean basin, in Latin America and in developing countries (85%). There is a strong lack of technological adoption in packages of feeding and land use in small-scale farms. To increase competitiveness, it would be of great interest to deepen the knowledge of how innovation was selected, adopted, and spread. The objective of this research was to select strategic feeding and land use technologies in familiar mixed dairy sheep systems and later assess dairy sheep farms in Spain.
El Programa de Innovación Agropecuaria Local (PIAL) posee una amplia diseminación de acciones en cientos de fincas, buscando alternativas locales que le den solución a las necesidades de prácticas sostenibles con carácter agroecológico, para ello se hace necesario demostrar la efectividad económica del desarrollo a nivel de finca. Este artículo desarrolo un análisis de costo-beneficio que es una herramienta de toma de decisiones para desarrollar sistemáticamente información útil acerca de los efectos deseables e indispensables.
Les grandes exploitations agricoles créées dans le cadre de la loi de mise en valeur agricole de 1983 dans le Sahara algérien étaient vouées à une production céréalière sous pivot. L’objectif était de développer économiquement des régions sahariennes pour partie marginalisées, ainsi que de réduire la dépendance chronique en céréales du pays. L’État a considérablement investi pour équiper ces exploitations agricoles dans le cadre d’un vaste plan de développement rural. Mais trente ans après la parution de la loi, les réalisations demeurent limitées au regard des objectifs initiaux.
The tools of biotechnology present an opportunity to infuse a new round of technology into Indian agriculture, which has been going through "technology fatigue" in recent period. These technologies follow from the conventional plant breeding techniques and complement them in improving crops to resist biotic and abiotic stresses, break yield barriers, and sustain yields in the face of resource degradation and climatic change.
This study aims to analyze the evolution of Brazilian agricultural production from the 1960s to now and summarizes some of the main findings from the historical view of Brazilian agriculture development. The arguments should rest here on how technical change and the national system of innovations have built an institutional environment to boost the agricultural sector, particularly in the past few decades. It is not easy to describe the path of Brazilian agricultural development , but organizing some important historical facts can help creating a full picture.
This paper assesses the role of economic, social, political and organizational processes on technology adoption in smallholder livestock production systems based on innovation systems perspective. Functions of the innovation systems framework was used to assess the missing links in the dairy sector value chains
This article rebuts the argument that shortcomings in Bt cotton studies and divergence between yield gains and extent of adoption of Bt hybrids make it impossible to conclusively say anything about the impact of genetically modified seeds. Further, it points out that there have been numerous studies that have controlled for selection and cultivation bias, and concluded that Bt cotton has had statistically significant positive yield effects.
This paper (Part I) present a case study of work conducted by the International Centre for Tropical Agriculture (CIAT) to adapt network mapping techniques to a rural and developing country context. It reports on work in Colombia to develop a prototype network diagnosis tool for use by service providers who work to strengthen small rural groups. It is complemented by a further paper in this issue by Louise Clark (Part II) which presents work to develop a network diagnosis tool for stakeholders involved in agricultural supply chains in Bolivia.
