Conteúdo:	Objective: The environmental performance in controlling sediment production was evaluated in a microcatchment in Iguatemi(MS), relating sediment production to the NDVI vegetation index between 2022 and 2024. Theoretical Framework: Quantifying suspended sediments is essential in hydrosedimentologicaland erosion studies in watersheds. The environmental performance index proposed by D’Agostini, Denardin, & Lemainski (2017) calculates the environment's capacity to dissipate the rainfall erosivity, and the results indirectly reflect human action through different proportions of land use and cover, and the types of management applied to them. Method: An automated system with level, turbidity, and rain gauges estimated the concentration of suspended solids during 59 erosive rainfall events. Results and Discussion: Throughout monitoring time, the micro-basin exported about 21.6 Mg of sediments, influenced mainly by areas without vegetation cover and by livestock trampling. The erosivity dissipation index (IDE) varied between 0.64 and 0.99, following the NDVI, exceptin periods without the presence of cattle, when the IDE remained high even with less vegetation cover. Research Implications: Highlighting the importance of conservation practices, vegetation recovery, and cattle exclusion in the headwater area to reduce sediment load and improve the micro-basin's environmental performance. Originality/Value: Contributing to the literature by studying the environmental performance of managing an area with a predominance of sandy soils and in the process of environment recovery.
