Findings from a survey on sources of income and land allocation outcomes of 578 households from 26 communities with diverse ethnic composition at distinct environmental settings in Ucayali (Peruvian Amazon) are used to contrast livelihood strategies featuring high forest and high agriculture dependency, examining whether agricultural intensification can be linked to lower deforestation. A typology of households based on their land use allocation profile was used to assess current and cumulative cleared land.
Con la finalidad de aportar conocimiento al análisis de las cadenas productivas maderables y no maderables, en el presente estudio se identifican las más relevantes en el subsector forestal del Estado de México, en función de la importancia socioeconómica y competitividad que tienen en el ámbito primario y secundario, y así aportar información para que los tomadores de decisión hagan uso más eficiente de los recursos destinados a la investigación, generación, validación y transferencia de tecnología, ya que la ciencia, innovación y desarrollo son actividades esenciales y generadoras de camb
Providing food and other products to a growing human population while safeguarding natural ecosystems and the provision of their services is a significant scientific, social and political challenge. With food demand likely to double over the next four decades, anthropization is already driving climate change and is the principal force behind species extinction, among other environmental impacts. The sustainable intensification of production on current agricultural lands has been suggested as a key solution to the competition for land between agriculture and natural ecosystems.
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.
Este trabajo tiene como objetivo general mostrar la relación entre las variables de la cultura organizacional del sistema de empresas de la comunidad indigena de Nuevo San Juan Parangaricutiro, Michoacán y las formas de manejo forestal a través del análisis situacional.
Climate forecasts have shown potential for improving resilience of African agriculture to climate shocks, but uncertainty remains about how farmers would use such information in crop management decisions and whether doing so would benefit them. This article presents results from participatory research with farmers from two agro-ecological zones of Senegal, West Africa. Based on simulation exercises, the introduction of seasonal and dekadal forecasts induced changes in farmers’ practices in almost 75% of the cases.
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
L’action locale est aujourd’hui confrontée au problème de changements climatiques, tant en termes de réduction des émissions de gaz à effet de serre que de gestion des impacts potentiels. La question particulière de l’adaptation aux changements climatiques émerge ainsi progressivement sur la scène locale et semble se généraliser depuis les évolutions législatives (Loi « Grenelle II ») qui rendent obligatoire la réalisation de plans climat-énergie territoriaux pour les collectivités de grande taille et des schémas régionaux climat-air-énergie.
This study presents a quasi-experimental analysis of the impact of FairTrade certification on the commercial performance of coffee farmers in Tanzania. In doing so the study emphasises the importance of a well-contextualised theory of change as a basis for evaluation design. It also stresses the value of qualitative methods to control for selection bias. Based on a longitudinal (pseudo-panel) dataset comprising both certified and conventional farmers, it shows that FairTrade certification introduced a disincentive to farmers’ commercialisation.
This paper compares lessons learned from nine studies that explored institutional determinants of innovation towards sustainable intensification of West African agriculture. The studies investigated issues relating to crop, animal, and resources management in Benin, Ghana, and Mali.The studies showed that political ambitions to foster institutional change were often high (restoring the Beninese cotton sector and protecting Ghanaian farmers against fluctuating cocoa prices) and that the institutional change achieved was often remarkable.
