The Acôgo stream watershed is located in the Miranda Depression. Thus, the basin is located in the transition between the Pantanal Plain and the Maracajú-Campo Grande Plateau, presenting social, cultural, and environmental dynamics typical of the region marked by the existence of large rural properties that carry out extensive livestock. The native vegetation suppression of Brazilian Cerrado for implantation of exotic pastures is facilitated by the flattened relief. This paper aims to analyze the dynamics of land use and coverage correlating it with the geomorphometric dynamics (Relief Energy) of this watershed. The Relief Energy map expresses a mathematical measurement of the relief, and originates from the synthesis between the Letters of Interfluvial Amplitude, Altimetric Amplitude and Declivity. Although the basin presents geomorphometric potential for morphodynamic stability, it is unbalanced when climatic, pedological, geological, and anthropic factors are analyzed, and geomorphometric stability proved to be a facilitator of anthropic occupation for the use of pastures. Its implementation led to a sharp deforestation, with only 24.82% of forest remnants left in the basin to 73.76% of pastures. The analysis and environmental planning of the basin should be based on the observance of the various elements involved, seeking to address anthropic and natural issues, aiming to contribute to its dynamic balance. Thus, it is indicated the need to adoption conservation practices of vegetation and improvement of existing pastures, which can meet the needs of economic activity without the continuity of the removal of forest remnants.
