Global adoption of transgenic crops reached 67.7 million hectares in 2003 from 2.8 million in 1996. Delivery has occurred almost entirely through the private sector and adoption has been rapid in areas where the crops addressed serious production constraints and where farmers had access to the new technologies. Three countries (USA, Argentina and Canada), three crops (soybean, cotton and maize) and two traits (insect resistance and herbicide tolerance) account for the vast majority of global transgenic area.
This paper addresses four questions: · What lessons can be drawn from the "rise and decline" of NARS in Africa? · What can African research managers learn from some of the successful reforms of NARS in Asia and Latin America over the past 10 to 15 years? · What are the major challenges facing the NARS in the ASARECA region in the coming 10-20 years? · What are the critical reforms and the incentives needed to develop pluralistic, accountable, productive and financially self-sustaining NARS in AFRICA?
Recent studies in the literature examining impact of government seed price intervention on adoption of Bt cotton get different results depending on the specifics of the situation analyzed. According to one study, reduction in seed prices enables farmers to buy seeds at lower prices and this can result in surge of area sown under Bt cotton. The other view holds that seed price interventions have little impact on the adoption rates rather these interventions may adversely affect firms’ incentives to innovate. Which of the two views characterize adoption of Bt cotton in India?
El objetivo de la investigación es identificar las principales estrategias sociales y productivas utilizadas por las fincas cafetaleras que ha logrado sobrellevar las crisis del sector en El Salvador. Tomando en cuenta la productividad promedio en quintales por manzana, la cual ha pasado de nueve quintales en la cosecha 2008-2009 a tres en la cosecha 2013-2014. El estudio se planteó como un diagnóstico basado en documentación secundaria y recopilación de datos primarios como entrevistas y grupos focales con productores del sector representativos del problema al que se buscó responder.
Este informe trae un registro del trabajo realizado en una campaña de promoción a la agricultura sustentable. Se realizó un taller en la comunidad con la logística y diseño didáctico propicio para que se pudieran recoger insumos suficientes de cómo decir en palabras sencillas a una persona agricultora que es mucho más beneficioso realizar actividades sin insumos químicos, reconociendo los riesgos que produce en la salud y en el ambiente continuar haciendo uso de agroquímicos, de esa manera fue como se obtuvo el nombre de la campaña “Por una vida sana sembremos consciente, en armonía con el
Este informe describe los cambios y las dinámicas actuales de los vínculos urbano-rurales enfocandose en el análisis de los circuitos cortos de comercialización (CCC) e iniciativas empresariales exitosas que valorizan los sistemas alimentarios locales
Este documento tiene como propósito avanzar en un análisis del sector agropecuario en Colombia desde una perspectiva territorial. La base de este análisis es el reconocimiento expreso de la heterogeneidad territorial presente en Colombia y de la necesidad de contribuir con insumos técnicos que permitan reconocer las diferencias para así poder identificar de manera más precisa oportunidades para un sector que tiene potencial de desarrollo y que en un contexto de construcción de paz, puede ser fundamental para un crecimiento sostenible e inclusivo.
The turn of agrarian sciences and agricultural extension from reductionist and transfer of technology, respectively, towards systemic approaches has transformed agricultural/rural development thinking in the last decades. Nevertheless, the emergence of Agricultural Innovation Systems (AIS) has to confront a number of gaps among which the expert – lay knowledge gap is of major importance. This paper aims at exploring such a gap as well as obstacles to participatory development from a critical realist point of view.
There is an emerging body of literature analysing how smallholder farmers in developing countries can benefit from modern supply chains. However, most of the available studies concentrate on export markets and fail to capture spillover effects that modern supply chains may have on local markets. Here, we analyse the case of sweet pepper in Thailand, which was initially introduced as a product innovation in modern supply chains, but which is now widely traded also in more traditional markets.
Natural resource management practices, such as the System of Rice Intensification (SRI), have been proposed to tackle agricultural challenges such as decreasing productivity growth and environmental degradation. Yet, the benefits of system technologies for farmers are often debated. Impacts seem to be context-specific, which is especially relevant in the small farm sector with its large degree of agroecological and socioeconomic heterogeneity. This was not always considered in previous research.
