Analyze of the dynamics temporal of use and occupation from soil in the county of Conceição do Araguaia-PA (1985-2020)

Abstract

With the needs human of consumption consequently changes the environment in its natural setting of landscapes over the years, can be reflected and characterized in the forms of use and land occupation. In this sense, human actions in the environment are at the center of socio-environmental problems. In the Brazilian Amazon and in the region of Conceição do Araguaia – Pará, the process of use and occupation soil is greatly influenced of agribusiness practices that along of the last thirty-five years grew significantly. In order to assess the influence of these practices on the multitemporal configuration of landscapes, this study aimed to analyze the temporal dynamics of use and occupation of soil in the municipality of Conceição do Araguaia-PA, from 1985 to 2020, through data collection from the Mapbiomas platform, using remote sensing techniques to produce maps of land use and occupation through digital processing of satellite images. Thus, 4 classes of use and occupation were identified, being the native vegetation, in addition to the classes of agriculture, other uses and bodies of water. The results showed an increase in the agricultural class around (40%) with a consequent reduction in the area of ​​native vegetation of the territory of (40%), stability was maintained in the class of other uses and a considerable reduction in water bodies of (15 km²). With the verification of deforestation in the evaluated municipality, agropastoral activities would be the main cause of this forest loss.
