L’agroécologie s’inscrit dans le registre de l’écologie, qui s’intéresse aux interactions - et à leurs conséquences - entre l’homme et son milieu, en tentant de minimiser les effets négatifs de certaines des activités humaines. Elle vise la préservation de l’environnement, le renouvellement durable des ressources naturelles nécessaire à la production (eau, sol, biodiversité...) et l’économie d’utilisation des ressources non renouvelables.
L’édition annuelle de Défis Sud propose un regard sur les agricultures, avec des faits, des chiffres et des prévisions. Face à l’augmentation de la population, au réchauffement climatique et à la perte de ressources naturelles, les solutions proposées pour répondre au défi de la sécurité alimentaire mondiale devraient davantage miser sur l’agriculture familiale et l’agroécologie. En 2018 les agricultures familiales seront encore menacées.
Este folleto describe brevemente el proyecto "Desarrollo de Capacidades para los Sistemas de Innovación Agrícola en El Salvador", implementado por la FAO en conjunto con el Centro Nacional de Tecnología Agropecuaria y Forestal “Enrique Álvarez Córdova” (CENTA), del Ministerio de Agricultura y Ganadería (
This study estimates the mitigation potential of agricultural practices supported by IFAD’s current investments in agricultural development to provide guidance for the design of future IFAD investments. We use data from field studies in the scientific literature to estimate the effects of a large set of agricultural practices promoted by IFAD (and other development agencies) on soil organic carbon stocks, nitrous oxide emissions from soils, and methane emissions from rice paddies.
Este documento describe el Proyecto Internacional BIOMAS-CUBA, enfocado a utilizar la biomasa como fuente renovable de energía, contribuir a mejorar las condiciones de vida, y lograr la coexistencia entre mitigación y adaptación al cambio climático, seguridad alimentaria y sostenibilidad energética en el medio rural. BIOMAS-CUBA abarca la producción y utilización de biodiesel y biogás, la gasificación de biomasa y la producción de bioproductos.
El estudio se realizó para conocer la contribución de la escuela de campo a productores en la capacitación y divulgación de la tecnología milpa intercalada en árboles frutales (MIAF). Una tecnología que contribuye en aumentar la producción de maíz y frijol e incorporar la producción intensiva de frutales de calidad comercial, eleva los ingresos, el empleo familiar y la captura de carbono del medio ambiente.
This article combines innovation intermediary and technological innovation systems literature to develop fundamentals of an approach for analysing how organisations acting as intermediaries support firms in eco-innovation and potentially contribute to technological innovation system functions. The operationalisation of the analytical approach is illustrated using case studies on a total of eight support organisations acting as intermediaries in the region of Scania, Sweden and North Rhine Westphalia, Germany.
The importance of extension services in helping smallholder farmers to address the many challenges of agricultural production cannot be over-emphasized. However, relatively few studies have been conducted that investigate how the capacities of agricultural extension agents can be built to more effectively assist smallholder farmers in managing climate risks and impacts. As climate change is a key threat to smallholder food production, addressing this issue is increasingly important.
Weather risk is a serious issue in the African small farm sector that will further increase due to climate change. Farmers typically react by using low amounts of agricultural inputs. Low input use can help to minimize financial loss in bad years, but is also associated with low average yield and income. Increasing small farm productivity and income is an important prerequisite for rural poverty reduction and food security. Crop insurance could incentivize farmers to increase their input use, but indemnity-based crop insurance programs are plagued by market failures.
Genetically engineered (GE) foods apply new molecular technologies to Widely adopted in the United States, Brazil, and Argentina for the p corn, soybeans, and cotton, they are practically banned in Europe and tigh throughout the world. We have found that GE foods have significantly incr of corn, soybean, and cotton, and lowered their prices, thus improving food foods have already contributed to a reduction in the use of pesticides and
