The anthropogenic actions, the population growth and the economic growth may cause deterioration of environmental quality, due to the lack of planning on land use and land cover and the adoption of conservation practices. Thus this paper has as its main goal to determine the use classes and the land cover Permanent Preservation Area around the watersheds and streams according to the environmental law (Federal law n°12,651 from 2012 with a new text determined by law 12,727 from October 17th 2012). The watershed is located in Igaraçu do Tietê (SP) town, it lies between the coordinates 48° 36' 12 to 48° 34' 3 of longitude W Gr. and 22° 35' 49 to 22° 30'38 of latitude S, adding up to an area of 3338.22 hectares. It was used the Geographic Information System GIS IDRISI-Selva to generate land use and the land cover maps and its conflicts in the PPA areas. The mapping outcomes from land use and land cover added up to six use classes which are sugarcane (2879.35 ha), forest (255,93 ha), pasture (81.51 ha), real estates (19.35 ha), artificial reservoir (29.37 ha) and floodplain (72.71 ha). The most expressive in the land use was the sugarcane crops which occupies 86.25% of the territory and the conflicts in PPA areas presented in the watershed were 76.45 ha, being the sugarcane area the evidenced one adding up to an area of 52.85 ha (69.13%).
