El servicio de extensión agrícola es uno de los principales vínculos entre la producción y el uso del conocimiento para la agricultura de los países en desarrollo. En la literatura, se han identificado agentes que actúan como intermediarios para vincular a dos o más actores que no se encuentran conectados. Sin embargo, pocos estudios abordan los mecanismos que éstos utilizan para intervenir y menos aún, una tipología que los caracterice e integre.
El objetivo del presente artículo fue analizar los flujos de conocimientos de tecnología en la producción de jitomate (Lycopersicon esculentum) en invernadero, estimando parámetros de redes sociales al inicio de las escuelas de campo en 2010 y a su término en 2011. Se trabajó con productores de pequeña escala del medio rural en el estado de Oaxaca que participaron en las escuelas de campo para la transferencia de tecnología. La selección de la muestra fue dirigida tomando productores asistentes y no asistentes a las escuelas de campo
Global climate change and food security are complex and closely intertwined challenges. A key requirement for dealing with them successfully is that agriculture becomes more eco-efficient. As researchers work toward this goal, they must always ask, “Efficiency for whom?” Finding answers to this question requires that research be conducted from a systems perspective in a broadly participatory manner involving complex collaborative arrangements.
Este estudio analizó la evolución de una red de innovación entre productores de hule natural durante tres periodos de observación (dos olas o tres años), y evaluó cómo los productores reaccionan a diferentes innovaciones en un momento dado. Las prácticas de innovación fueron agrupadas en tres actividades: control de plagas y enfermedades, establecimiento y manejo de plantaciones, y manejo de cosecha y poscosecha.
El objetivo de este trabajo fue identificar a los actores involucrados en sistema de innovación de los productores de maíz de la Región Centro de México, destacando el papel de los actores de soporte institucional en su adopción de innovaciones. Para ello, se entrevistaron 490 productores de maíz atendidos dentro del marco del programa MasAgro 2012, en los estados de Guerrero, Hidalgo, Puebla, Morelos, Estado de México y Tlaxcala. Se midió el grado de adopción de las innovaciones, y mediante la metodología de análisis de redes sociales se analizó la vinculación entre los actores.
The aim of this study was to identify the actors involved in the innovation system producers of corn Mexico Center Region, highlighting the role of the actors of institutional support in adoption of innovations. To do this, 490 corn producers served within the framework of MasAgro 2012 program, in the states of Guerrero, Hidalgo, Puebla, Morelos, State of Mexico and Tlaxcala were interviewed. The degree of adoption of innovations was measured, and using the methodology of social network analysis linking between actors analyzed.
This paper (Part I) present a case study of work conducted by the International Centre for Tropical Agriculture (CIAT) to adapt network mapping techniques to a rural and developing country context. It reports on work in Colombia to develop a prototype network diagnosis tool for use by service providers who work to strengthen small rural groups. It is complemented by a further paper in this issue by Louise Clark (Part II) which presents work to develop a network diagnosis tool for stakeholders involved in agricultural supply chains in Bolivia.

This article adds to the literature about the impact of social networks on the adoption of modern seed technologies among smallholder farmers in developing countries. The analysis centers on the adoption of hybrid wheat and hybrid pearl millet in India. In the local context, both crops are cultivated mainly on a subsistence basis, and they provide examples of hybrid technologies at very different diffusion stages: while hybrid wheat was commercialized in India only in 2001, hybrid pearl millet was launched in 1965.
In Sub-Sahara Africa, adoption rates of improved crop varieties remain relatively low, which is partly due to farmers’ limited access to information. In smallholder settings, information often spreads through informal networks. Better understanding of such networks could potentially help to spur innovation and farmers’ exposure to new technologies. This study uses survey data from Tanzania to analyze social networks and their role for the spread of information about improved varieties of maize and sorghum.
