SPATIAL ANALYSIS TECHNIQUES IN THE IDENTIFICATION OF SUITABLE AREAS FOR THE IMPLEMENTATION OF A LANDFILL IN THE MUNICIPALITY OF DIVINÓPOLIS, MINAS GERAIS

Abstract

Currently, one of the major urban challenges is the inadequate disposal of solid waste. The accelerated growth of the population in recent years has caused numerous impacts on the environment, including the irregular disposal of waste, making the job of finding an environmentally viable place to dispose of it increasingly complex. Landfills are the most viable and safest options, as they manage to avoid contamination of water resources, air and soil. However, the choice of the appropriate location for the construction of a landfill remains one of the biggest problems due to all the variables involved. Thus, this article aims to determine, through geoprocessing tools, ideal areas for the implementation of landfills in the municipality of Divinópolis -MG. This objective was achieved through the Geographic Information System (GIS) and the analysis of Multiple Criteria. The final cartographic product was obtained from the combination of environmental, social and economic variables. The results showed that more than 60% of the entire area of the municipality has areas that are not feasible to implement a landfill and that approximately 27% of the entire area is considered of average suitability and, therefore, should be analyzed in more depth.
