Análise da Alteração da Cobertura Vegetal e Uso da Terra no Município de Aguiarnópolis, Tocantins

Abstract

The landscapes suffer several changes of natural order or by human actions. The changes in the landscape in Brazil are mainly caused by agricultural activities that cause impacts on the vegetation cover and, highlighting in particular the Amazon biome, which suffers from deforestation. These impacts are also influenced by the actions of government projects from the last century that promoted the occupation of this region, and encouraged the occupation of land by agriculture and livestock, mainly with livestock. And these changes are evident in the municipality of Aguiarnópolis/Tocantins, located in the extreme north of the State, present in an area of transition between Amazonian-Cerrado biomes, displaying livestock as the main activity of land use. Therefore, the objective of this work was to investigate the dynamics of vegetation cover and land use in the municipality of Aguiarnópolis/TO between the years 2013 and 2022, highlighting the vegetational physiognomies and activities that cause changes in the landscape of Aguiarnopolis. The information used for data spatialization were used images from the years 2013 and 2022 from the Landsat-8 satellite, obtained free of charge from the website of the National Institute for Space Research (INPE). The thematic classes obtained were Agriculture, Body of Water, Livestock, Urban Influence, Wooded Savannah without gallery forest, Forested Savannah, Secondary Vegetation with Palm Trees, Submontane Deciduous Forest, noting that there is 54.45% of original vegetation present in the study area until 2022, but demonstrating that the municipality has a high capacity for the growth of livestock, which may reduce the areas of present vegetation.
