Se evaluó la aceptación de una nueva tecnología de manejo integrado del cultivo de papayo en el ejido Miralejos, municipio de Soledad de Doblado, Veracruz, México. Se encuestaron 32 productores antes y después de asistir a eventos demostrativos en tres parcelas del ejido. El análisis multivariado de componentes principales mostró evidencia significativa que engloba la opinión de los encuestados respecto a los cambios de actitud positiva hacia la tecnología
This study identifies entry points for innovation for sustainable intensification of agricultural systems. An agricultural innovation systems approach is used to provide a holistic image of (relations between) constraints faced by different stakeholder groups, the dimensions and causes of these constraints, and intervention levels, timeframes and types of innovations needed. The authors aim at showing that constraints for sustainable intensification of agricultural systems are mainly of economic and institutional nature.
Relying on cross-sectional data from 300 smallholder rice farmers, the study examined the effects of agricultural extension on improved rice variety adoption and farm income in northern Ghana. A recursive bivariate probit (RBP) model was used to assess the effect of agricultural extension on adoption while regression with endogenous treatment effect model (RETEM) was adopted to evaluate the effect of agricultural extension on farm income. The results indicate a statistically significant effect of agricultural extension on both adoption and farm income.
Low and slow adoption of improved agricultural technologies among smallholders often frustrate technology development and promotion efforts in the developing world. That is especially true for technologies requiring high initial investment. This study investigates how increasing farmers' awareness and exposure to new agricultural technologies through the creation of systematic linkages in the research-to-development continuum affect adoption. The double hurdle and duration analysis models were applied to a sample of 820 smallholder households producing wheat and barley in Syria.
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.
El presente trabajo ofrece un panorama global del mercado existente de los productos de origen animal, principalmente de carne y leche, con el propósito de obtener un panorama general de la producción caprina y valorar algunas perspectivas de la producción caprina en México y el mundo. Se enfatiza en los sistemas tradicionales de producción caprina y las perspectivas de desarrollo de la producción caprina a distintos niveles: local, regional, nacional e internacional

While livestock constitute a strategic sector to reduce poverty and enhance growth in developing countries, decision makers often lack data reflecting the diversity of livestock functions and systems. The authors therefore mobilised the Livestock Sector Investment Policy Toolkit to assess the economic contributions of livestock in Zambia. Valuing their plural contributions by system, we found that mixed rainfed systems were the main contributors to added value, even if specialised intensive systems provided around 45% of meat and milk production.
Given the diversity and context-specificity of innovation systems approaches, in March 2007 the World Bank organized a workshop in which about 80 experts (representing donor agencies, development and related agencies, academia, and the World Bank) took stock of recent experiences with innovation systems in agriculture and reconsidered strategies for their future development. This paper summarizes the workshop findings and uses them to develop and discuss key issues in applying the innovation systems concept. The workshop’s recommendations, including next steps for the wider
