Les investissements dans les agrocarburants en Afrique constituent une véritable question de développement. Ils sont pleinement concernés par le débat sur les acquisitions de terres à grande échelle et exposent les populations et les agricultures africaines à plusieurs types de risques. Dans le même temps, ils représentent une opportunité dans des pays où l’accès à l’énergie est sans doute un des principaux facteurs de blocage au développement. Certaines formes d’investissement peuvent être encouragées, à condition qu’elles profitent aux économies locales.
Cet article défend l'idée que les petites exploitations agricoles doivent être placées au cœur du processus de développement, principalement dans les pays du Sud, notamment parce que la moitié des populations qui, dans le monde, souffrent de la faim, habitent des zones rurales et disposent de moins de 2 hectares, et parce que près de 2 milliards d'êtres humains dépendent de l'agriculture familiale. L'auteur, éminent représentant de la FAO, préconise l'insertion de la petite exploitation dans les circuits agro-industriels.
El objetivo de este trabajo es dar a conocer cómo se han desarrollado los vínculos entre el sector productivo y la Estación Experimental de Pastos y Forrajes “Indio Hatuey”. Se emprendieron una serie de medidas para la recuperación de la base alimentaria del ganado, con el empleo de prácticas alternativas y la aplicación de sistemas sostenibles de producción animal, las cuales tenían como principal objetivo el aumento de la producción, aun con pocos recursos
Este trabajo presenta una fase teórica orientada a la argumentación que sustenta la naturaleza y el alcance de las redes como estructuras interorganizacionales para apoyar el desarrollo integral con base en las capacidades de investigación, innovación y desarrollo tecnológico localizado. En una segunda fase se formulan las hipótesis de contrastación empírica.
This study refines the participatory management (PM) in agricultural extension education (AEE) by adopting a multidimensional approach. PM is a process where extension agent (EA) tries to provide a good situation for AEE and share significant degree of power with their farmers. The data were obtained from samples of 290 Iranian farmers in Torbat Heydarieh, Iran. Methodology was descriptive and correlation. There was directly and a statically significant relation between all of components of PM regarding in effective AEE. The PM is a panacea for improving the AEE.
The innovation system perspective acknowledges the contributions made by all stakeholders involved in knowledge development, dissemination and appropriation. According to the specific agricultural production system, farmers adopt innovations, modify them or innovate on their own. This paper examines the role of farmers' experiments and innovations in Cuba's agricultural innovation system (AIS), identifies knowledge exchange encounters and describes some strategies implemented to institutionalize farmers' experiments and innovations.
This study examines the role of public–private partnerships in international agricultural research. It is intended to provide policymakers, researchers, and business decisionmakers with an understanding of how such partnerships operate, how they promote the exchange of knowledge and technology, and how they contribute to poverty reduction.
African farming systems are highly heterogeneous: between agroecological and socioeconomic environments, in the wide variability in farmers’ resource endowments and in farm management. This means that single solutions (or ‘silver bullets’) for improving farm productivity do not exist. Yet to date few approaches to understand constraints and explore options for change have tackled the bewildering complexity of African farming systems. In this paper we describe the Nutrient Use in Animal and Cropping systems – Efficiencies and Scales (NUANCES) framework.
One of the most important challenges for the researchers in the 21st Century is related to global heating and climate change that can have as consequence the intensification of natural hazards. Another problem of changes in the Earth's climate is its impact in the agriculture production. In this scenario, application of statistical models as well as development of new methods become very important to aid in the analyses of climate from ground-based stations and outputs of forecasting models. Additionally, remote sensing images have been used to improve the monitoring of crop yields.
En esta nota breve se analiza, desde una perspectiva crítica, la práctica de la extensión rural realizada por profesionales agrónomos en Mendoza, Argentina. En base a una amplia revisión bibliográfica y análisis documental sobre programas de desarrollo rural, analizamos los condicionamientos socio-culturales de dicha práctica, elementos que inciden sobre la concepción, ejecución y orientación de las estrategias de desarrollo promovidas por estos sujetos y sus instituciones
