Estudios de casos sobre cambio tecnológico en la producción de frijol en América Latina uri icon

abstract

  • Case studies from Costa Rica, Guatemala, and Colombia are reviewed on improved technology adoption to find out to what degree has this technology been adapted to the needs of low income farmers, consider the relationship between new var. adoption and the changes in farm management, and examine the socioeconomic and institutional context as determinant of opportunities for technological change. The impact of new technology is substantially related to the effectiveness in seed production and distribution, markets, extension, and on-farm research. The design of improved technology for farm systems should be based on the specific biotic and socioeconomic circumstances of a place. Case studies on beans and the strategy of an approach for disease resistance for small farmers in marginal areas show that it is possibe to make progress, like in the case of Costa Rica, where bean production has doubled during the 80's.

  • Case studies of Costa Rica, Guatemala, and Colombia on the adoption of improved technology were reviewed to (1) determine to what extent technology has been adapted to the needs of farmers with limited resources, (2) analyze the relationship between adoption of new varieties and changes in farm management, and (3) examine the socioeconomic and institutional context as a determinant factor of opportunities for technological change. The impact of new technology is critically related to the effectiveness of seed production and distribution, market points, extension, and on-farm research. Improved technology for farming systems should be designed on the basis of site-specific biotic and socioeconomic characteristics. Case studies of bean farmers in marginal areas, where a disease resistance strategy was applied, indicate that bean production can be improved outstanding example is the case of Costa Rica, where production doubled in the 1980s
