The growing unplanned expansion of agricultural activities without a prior survey of the potential and limitations regarding land use, presents a significant risk of deterioration of the environment. Unplanned agricultural activity represents a great environmental risk, increasing the rate of erosion by occupying inappropriate areas due to its topography, or by polluting activities that can harm adjacent ecosystems, either by silting up surface water flows or even by contamination of agrochemicals. This research aimed to develop a geoenvironmental diagnosis for the region of the Tapacurá basin in areas of possible occurrence of land use conflict. Using radar scenes from the SRTM (Shuttle Radar Topography Mission) mission, submitted to processing and analysis in Geographic Information Systems (GIS). As a result of this research, the digital delimitation of the area of interest in the vector format was obtained, as well as the slope maps reclassified according to the classes recommended by Embrapa Solos; adding to these, the morphometric characteristics of the hydrological compartments contained in the area of interest were obtained, namely: drainage network, length of the main thalweg, perimeter of the basin, sum of the water courses and the density of the drainage network. These parameters were calculated by the ARCSWAT module, on ESRI's ArcGIS 9 platform. Once these parameters were calculated, the slope maps, roughness index, use and occupation of the current soil and potential to carry out the environmental diagnosis of land use conflict were made.
