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.
En Afrique, le droit sur le sol doit d’abord permettre l’accès à celui-ci. Pour l’agriculteur familial, ce droit est généralement celui des coutumes, que des procédures innovantes permettent de sécuriser. Les investisseurs préfèrent les titres de propriété ou les attributions du sol par l’État. Le droit foncier peut aussi être mobilisé pour garantir des crédits. Mais des contraintes limitent ce droit, résultant de l’existence de ressources naturelles renouvelables (ou non) dont l’exploitation concurrence celle de l’agriculture.
Rural Advisory Services (RAS) are increasingly recognised as critical to agricultural and rural development. They provide rural communities with wide range of skills and knowledge and facilitate their interactions among the different actors to help them access support and services required for improving their livelihoods. Family Farmers are one of the important clients of RAS as they are the most predominant type of farmers worldwide.
In this book, the authors assessed the role of biotechnology innovation for sustainable development in emerging and developing economies. This book compiles studies that each illustrate the potential, demonstrated value and challenges of biotechnology applications for sustainable agricultural innovation and/or industrial development in a national, regional and international context.
En este artículo se procura identificar, describir y comparar la concepción de extensión rural que guía a nivel subjetivo las prácticas de extensión de técnicos que trabajan en diez diferentes países latinoamericanos, para luego comparar estas concepciones con los modelos y lineamientos de extensión propuestos por la bibliografía. Para esto, primero se describen distintas concepciones de extensión que han tenido importancia en América Latina a lo largo de la historia, luego se presenta la metodología de investigación utilizada, presentándose por último los resultados a los que arribó
Con las nuevas demandas de la sociedad hacia las organizaciones de investigación para contribuir con mayor énfasis a los procesos de innovación, comienza a configurarse una nueva visión sobre el rol de la extensión en el conjunto de procesos innovadores.
Agricultural transformation and development are critical to the livelihoods of more than a billion small-scale farmers and other rural people in developing countries. Extension and advisory services play an important role in such transformation and can assist farmers with advice and information, brokering and facilitating innovations and relationships, and dealing with risks and disasters.
This book discusses innovation problems and opportunities for family farming in the different regions of the American continent, as well as the role of hemispheric, regional and national agrifood research systems. Likewise, it provides a description of the main innovation actions and projects promoted by IICA, and the main success cases over recent years.
The increasing complexity of technology development and adoption is rapidly changing the effectiveness of scientific and technological policies. Complex technologies are developed and disseminated by networks of agents. The impact of these networks depends on the assets they command, their learning routines, the socio-economic environment in which they operate and their history.
The main goal of this report is to provide a brief summary of land-use change in Amazonia within the focus countries of Bolivia, Brazil, Colombia, Ecuador and Peru. This report will mainly focus on the analysis and discussion of land-use change status and trends since 1970’s, a period when considerable changes started to be evident. Analyses were supported from a literature review and land use databases and maps for Andean countries (CIAT) and Brazil (INPE).
