Resumo: In this study, changes in land use and land cover were analyzed in a watershed located in an expanding soybean zone, transitioning between the plateau and the erosion scarp in the central region of the state of Mato Grosso do Sul. The analysis was conducted using the historical series from the MapBiomas Network, collection 7.1 (1985-2021). In the years 2021, marked by a drought situation, and 2023, with rainfall distribution within historical averages, vegetation radiometric indices were calculated from Sentinel-2 images. This refinement allows us to observe interannual changes in land cover and use, as well as the effects of drought on vegetation. In 1985, native vegetation consisting of forest formations, savannahs, grasslands, and wetlands occupied 29.16% of the watershed area. In 2021, native vegetation increased to 30.02%, primarily due to the natural regeneration in abandoned pasture areas on steep terrain. Throughout the analyzed period, the predominant land use class was pasture, occupying 50.04% of the area in 1985 and 37.41% in 2021. The reduction in pasture area is a result of the expansion of soybean cultivation, which accounted for 11.81% of the total watershed area in 2021. Despite the area being part of a sustainable use Conservation Unit, the observed degradation processes are like those in unprotected areas.

El análisis fue realizado utilizando la serie histórica de la Red MapBiomas, colección 7.1 (1985-2021). En los años 2021, marcados por una situación de sequía, y 2023, con distribución de lluvias dentro de promedios históricos, se calcularon índices radiométricos de vegetación a partir de imágenes del Sentinel-2. Este refinamiento permite observar los cambios interanuales en la cobertura y uso del suelo, así como los efectos de la sequía sobre la vegetación. En 1985, la vegetación nativa compuesta por formaciones forestales, sabanas, pastizales y humedales ocupaba el 29,16% del área de la cuenca hidrográfica. En 2021 la vegetación autóctona aumentó hasta el 30,02%, debido principalmente a la regeneración natural en zonas de pasto abandonadas en terrenos inclinados. Durante el período analizado, la clase de uso predominante fue el pastizal, que ocupaba el 50,04% del área en 1985 y el 37,41% en 2021. La reducción en el área de pastizal es consecuencia del avance del cultivo de soja, que en 2021 representaba 11,81% del área total de la cuenca hidrográfica. A pesar de que el área está incluida en una Unidad de Conservación de uso sostenible, los procesos de degradación observados son los mismos que los de áreas no protegidas.Neste trabalho foram analisadas as mudanças no uso e cobertura da terra em uma bacia hidrográfica que se encontra em zona de expansão da soja, na transição entre o planalto e a escarpa de erosão, na região central do estado de Mato Grosso do Sul. A análise foi conduzida utilizando a série histórica da Rede MapBiomas, coleção 7.1 (1985-2021). Nos anos de 2021, marcado por uma situação de seca, e 2023, com distribuição de chuvas dentro da média histórica, foram calculados índices radiométricos de vegetação a partir de imagens Sentinel-2. Esse refinamento permite observar as mudanças interanuais na cobertura e uso da terra e os efeitos da seca sobre a vegetação. Em 1985 a vegetação nativa composta por formações florestais, savânicas e campo alagado, ocupava 29,16% da área da Bacia Hidrográfica do Córrego Limpo (BHCL). Em 2021, a vegetação nativa aumentou para 30,02%, principalmente devido à regeneração natural em áreas de pastagens abandonadas em terrenos declivosos. Durante o período analisado, a classe de uso predominante foi pastagem, ocupando 50,04% da área em 1985 e 37,41% em 2021. A redução na área de pastagem é consequência do avanço da cultura da soja, que em 2021 correspondia a 11,81% da área total da BHCL. Apesar da área estar inserida em uma Unidade de Conservação de uso sustentável, os processos de degradação observados são os mesmos que os de áreas não protegidas.Editora Unimontes2024-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigoapplication/pdfhttps://www.periodicos.unimontes.br/index.php/cerrados/article/view/681310.46551/rc24482692202401Revista Cerrados; v. 22 n. 01 (2024): Revista Cerrados (In Progress); 03-292448-26921678-8346reponame:Revista Cerrados (Montes Claros.
