Résumé
The paper presents the results of a study about public policies in favor of agro ecology in Latin America and the Caribbean. The objective was to analyze the policies or tools that influence the adoption of agro-ecological practices and identify their main effects. The method involved the application of a common analysis guide in 8 countries based on bibliography, secondary data and interviews. There are few cases of nominally agroecology policies, but there is always a regulation of organic certification extended to agroecological products that promotes either an approximation or a tension between the two conceptions. The construction of agroecological policies involves three processes: pressure from the social movement, crises and government initiatives. There is a large variety of instruments dispersed in different public sectors with great difficulty of coordination. However, actions for access to land, water, credit and technical assistance for family and peasant farmers are the best basis for negotiating more specific programs for the agro ecological transition.
