DINÂMICA DE USO E COBERTURA DO SOLO NO MUNICÍPIO DE ANANÁS, TOCANTINS (2010-2020)

Abstract

This text aimed to analyze the dynamics of the landscape in the Tocantins municipality of Ananás, with a view to producing information that supports territory planning and environmental conservation. For the elaboration of the maps of this research, images from the years 2010 and 2020 were used, respectively from the satellites Landsat 5, sensor Themathic Mapper - TM, and Landsat-8, sensor Operacional Land Imager - OLI, which are acquired free of charge on the website from the National Institute for Space Research. For image processing, Spring Geographic Information Systems, version 5.4.3 and QGIS version 3.18 were used. The results show that the municipality of Ananás has been suffering an accelerated transformation in the landscape, since livestock occupies 47.64% of the territory analyzed, adding these changes to the implementation of forestry projects, especially eucalyptus with 2.73% and the urban influence with 0.25%, which indicates a trend towards the homogenization of these economic activities [livestock and forestry] in the north of Tocantins, specifically in Ananás. Thus, it is considered important and urgent to invest/implement government public policies for the diversified use of land, with actions that value environmental conservation combined with agroecology and other economic activities of the State, such as peasant agriculture.
