In this sense, the present article aims to map and identify the activities of land use and cover around the Ribeirão João Leite reservoir, from the perspective of evaluating your level of anthropic pressure. For such was made use of Digital Image Processing (IDP)techniques and GIS modeling. The results show that despite the presence of protected areas, like the Ecological Park Altamiro Moura Pacheco and State Park of João Leite, assist in containing the pressures surrounding the reservoir, 42,20% of your area presents considered degrading activities. Counting with the presence of an open air garbage deposit near him.
