Etnobotânica de Leguminosae entre agricultores agroecológicos na Floresta Atlântica, Araponga, Minas Gerais, Brasil

This study describes the richness of Leguminosae used by 21 traditional farmers in coffee agroforestry systems (AFS) and forest fragments of the Atlantic Forest, in the municipality of Araponga, Minas Gerais, Brazil. It also presents the use categories, relative importance and the species similarity between the AFSs. Data were collected through semi-structured interviews and participant observation, between August 2005 and November 2006, directed during random walks in seven AFSs and forest fragments surrounding the State Park of Serra do Brigadeiro. The farmers cited 59 species of Leguminosae, of which 86% are native to the Atlantic Forest and used in ancient cultural practices, such as to make bullock carts. Twelve categories of use were established, among them the most important were fertilizer and firewood (21 spp each); in the AFSs, species used for soil fertilization (18 spp) are the most utilized, and in the forest, the species for firewood and technology (17 spp.) The relative importance index showed that in the forest, Piptadenia gonoacantha showed 83% of agreement for the use as wood for fencing pastures, while in the AFSs, Inga edulis scored 100% as food. The AFSs studied show little similarity of species (0.42 of the Sorensen scale), due to the selection promoted by the farmers, thus, providing room for the conservation of useful species of Leguminosae.

Recuperação de áreas degradadas através de sistemas agroflorestais: a experiência do Projeto Agrofloresta, sustento da vida

PETROBRAS started in 2003 the implantation of agroforestry systems as an alternative to recuperate degraded areas at Oiteirinhos Farm, of its property, located in the biggest terrestrial field of oil of Brazil, between the cities of Carmópolis and Japaratuba, at Sergipe. The project, idealized by the geologist Ismael Quirino Trindade Neto and called Agrofloresta, sustento da vida, has the model of agroforestry systems developed by Ernst Götsch as technical and theoretical references, which joins agricultural cultures with forest species. In this direction, it was evidenced that the practices adopted in the SAFs allow to join recovery, conservation and production, as it follows the biodiversity and the dynamics of the natural processes as basic principles of the practices adopted. Including social inclusion and economic return, the project expands the environmental aspect, turning into an action focused in sustainable development.
