The construction of adequate public policies for the development of Agroecology is a challenge that can only be tackled with the support of multidisciplinary teams and a comprehensive vision of the needs of the local communities. Furthermore, it is necessary to predict as far as possible what kind of constraints may arise during the application of these policies. The Public Policy theme seeks to bring together reports of experiences from different locations to serve as bases for designing and expanding public policies on Agroecology.
