The municipality of Minaçu, in the northern region of the state of Goiás, differs from many Brazilian municipalities due to the intense changes that have occurred in its territory. The municipality is known as the Brazilian capital of asbestos, an ore that gave rise to the occupation of the region, whose extraction has lasted six decades. In addition to the large pits opened by mining, the municipality also has two hydroelectric plants, in addition to part of their respective reservoirs, which occupy a large part of their land. The objective of this study was to analyze the land use and cover between the years 1988 and 2018 of Minaçu. For that, the data of land use of the MapBiomas project were used, also used for analysis of the conversion between the classes of the mapping from the initial year to the end of the period of analysis. The least significant classes for the period under analysis were non-vegetated area, mining, urban infrastructure and planted forest. The areas of natural vegetation, such as forests and savanna, were converted to areas for human use, mainly pasture, also had the largest areas flooded by the two reservoirs of hydroelectric plants present in the municipality. The data used enabled an efficient and low-cost study, which serves as a basis for a greater understanding of the dynamics of use and coverage, also serving as a basis for planning sustainable land occupation.
