Existe hoy una preocupación creciente acerca de cómo los sistemas de monitoreo y evaluación permiten generar nuevos conocimientos para la comprensión no sólo de los efectos e impactos de una intervención sino también sobre la manera en que suceden los cambios. Este trabajo presenta la metodología de sistematización de experiencias, entendida como una estrategia multiactoral para evaluar intervenciones de desarrollo con énfasis en los procesos y las lecciones aprendidas.
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.
Los artículos reunidos en este volumen se basan en las ponencias presentadas por los expertos que participaron en el seminario internacional “Políticas para la agricultura en América Latina y el Caribe: competitividad, sostenibilidad e inclusión social”, realizado en la sede de la Comisión Económica para América Latina y el Caribe (CEPAL) en Santiago los días 6 y 7 de diciembre de 2011.
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.
Innovations in the agri-food sector are needed to create a sustainable food supply. Sustainable food supply requires unexpectedly that densely populated regions remain food producers. A Dutch innovation program has aimed at showing the way forward through creating a number of practice and scientific projects. Generic lessons from the scientific projects in this program are likely to be of interest to agricultural innovation in other densely populated regions in the world.
The increasing demand for agricultural commodities is a major cause of tropical deforestation. However, pressure is increasing for greater sustainability of commodity value chains. This includes the demand to establish new crop plantations and pasture areas on already deforested land so that new forest clearing for agriculture is minimized. Where tree crops are planted as part of agroforestry systems on deforested land, this amounts to a form of re-agro-forestation which can generate environmental benefits in addition to crop production.
Millions of dollars have been invested in programs to encourage the adoption of sustainable farming practices associated with conservation agriculture (CA), including programs aimed at Samoan farmers. However, many smallholder farmers, including those in Samoa did not adopt the recommended practices. CA programs aimed at Samoan farmers were investigated, and participatory action research about the most recent program was conducted.
Regional agroecological systems are examples of complex adaptive systems, where sustainability is promoted by social networks that facilitate information sharing, cooperation, and connectivity among specialized components of the system. Much of the existing literature on social capital fails to recognize how networks support multiple social processes.
This book presents feedback from the ‘Territorial Agroecological Transition in Action’- TATA-BOX research project, which was devoted to these specific issues. The multidisciplinary and multi-organisation research team steered a four-year action-research process in two territories of France.

This paper explores the potential of the multi-strata design used in edible forest gardens based on studies during the establishment of edible forest gardens (the first four years) in the agricultural settings of a group of participating farms in Sweden. The design and species composition of such gardens, the kind of food they may provide, and how they would best fit into the present landscape are discussed.
