Conteúdo:	The aim of this study was to use geotechnologies to quantify and characterize the permanent preservation areas (PPA) in three important coffee regions in the south region of the State of Minas Gerais: São Sebastião do Paraíso, Machado and Três Pontas. Four categories of PPA’s were identified: drainage, springs, lakes and slopes steeper than 45 degrees. The mapping of land use was done with satellite images from TM/Landsat 5 in two different dates. The GIS TerraView and SPRING were used. The PPA was crossed with maps of land use for the two years studied. The resulting maps were crossed to obtain the evolution of land use in the PPA. All the study areas evaluated showed an unsuitable land use/occupation around 60%. The greatest degradation of PPA in the study areas was observed in the lakes’ category. The results showed that in the South of Minas Gerais, the Brazilian Forest Code is not respected as it should. However, despite the extensive areas with coffee plantation, this crop contributes relatively little to the degradation of areas of legal protection (approximately 4%).
