| Resumen en inglés | The Midwest region of Brazil has a high concentration of land and is the primary producer of grains and livestock in the country, activities with a negative impact on environment. Agrarian reform allows redistribution of land and reinforces family agriculture, which is considered to be favorable to environmental protection. The aim of this study was to use field and remote observations to verify the evolution of environmental preservation and land use in rural settlements in the Midwest region of Brazil. 54 settlements distributed in the region were analyzed. We used images from Landsat 5 satellite obtained by the Thematic Mapper sensor in 2004 and images from Landsat 8 satellite from 2014. The NDVI and NDWI vegetation indexes were used to classify urban, agricultural, pasture, savannah and forest areas. Forests declined in all states, however Mato Grosso, the only one with Amazonian forest, where settlements presented lowest compliance with environmental legislation. The evolution indicates the transformation of forest areas into savannah. Settlers predominantly engage in dairy farming, which requires large areas of land and thus exerts significant pressure on the environment. Productive areas are poorly exploited, and better technical assistance could have a significant impact on environmental protection |
