The project is based on participatory methodologies, such as diagnosis, reflection, discussion and training of social pacts. The project is being developed in rural settlements around the National Forest of Ipanema in Iperó/SP, Brazil. . Of the total of 150 families, about 40 participated in the project. Six young people were selected from the community to act as multiplier monitors. Exchange visits allowed them to share real experiences with rural farmers and to observe community organization and production in agroforestry. From a participatory diagnosis, farmers cited the species they would like to plant. Since only exotic species were cited in the diagnosis, the project prepared an illustrative material with native species. Planning workshops were held where farmers laid down the species and combinations that they would like to deploy. Thereafter, the demonstration units were deployed in the monitors' areas with exotic agricultural species and native species of medium and long cycle. It is believed that the project objectives have been achieved because, currently, several new voluntary initiatives to diversify production and deploy agroforestry are seen
