Resumo
In Brazil, since the beginning of its colonization, the degradation of the Brazilian biomes was present. At the
beginning of the eighteenth century this occupation reaches the lands where currently the city of Uberlândia (MG) is
located, along with it, also comes the process of degradation that extends to the present day. It is in this context, of
occupation of the Cerrado, that the Districts studied, Cruzeiro dos Peixotos and Martinésia, located in the northern
portion of the municipality of Uberlândia (MG), are inserted. The main objective of this work was to analyze the
changes in land use, in the referred Districts, between 1997 and 2017, from a socioenvironmental perspective. In the
development of this one, a study was carried out to detect what was altered in the natural area, by means of
overlapping, and comparison of cartographic data and remote sensing, obtained with the aid of satellite images,
considering the cuts of the years of 1997, 2007 and 2017. The research area, although in a differentiated way, went
through processes of urbanization and industrialization (inputs and agricultural equipment) and consequently
modernization of agriculture, changes in the technological, social, economic and mainly environmental fields. The
importance of knowing the real potentialities and limitations of use and occupation of a given area, through registries
and monitoring, allow the evaluation of future potentialities and impacts. The area studied was delimited from the
production of a base map which was created using images from the Google Earth program. These images were
transferred to digital format using ArcGIS and SPRING. The next step was the acquisition of TM and OLI images
LANDSAT 5 and 8, scale 1: 100,000, bands 3B, 4G and 5R, orbit / point 221/073 of the years 1997, 2007 and 2017
achieved in DPI / INPE - 2017. The bands 3B, 4G and 5R (sensor TM) and 3B, 5G and 7R (OLI sensor), orbit / point
221/073 from the years of 1997, 2007 and 2017 were selected for a better view of the relief, drainage and soil cover
in the study area. To enable interpretation, it was necessary to group some land use classes: Water, Forest Formation,
Cerrado, Pastures, Annual Culture, Forestry and Exposed / Burned Soils. In the area under study for the artificial
lakes of the Hydroelectric Power Plants they are small hydroelectric power plants or it has not increased a new type
of enterprise in the region that are the allotments of rural areas for recreational farms. The modernization of
agriculture was not restricted to new crops, reaching small landowners, and expropriating those who did not fit the
new model. In the Districts surveyed, what is perceived is that farmers who have not been able to keep up with the
modernization of agriculture rent their land for cultivation or pasture, with small parcels of land near their
headquarters being used for their use.
