The aim of this study was to evaluate the influence of deforestation on climate change in areas of agriculture and livestock exploitation in the city of Currais-PI. A space time analysis of land use and land cover in the municipality was carried out over a 32-year time series (1986 to 2018), correlating with meteorological variables. To perform the space time analysis Landsat 5 and Landsat 8 satellite images were used, acquired free of charge from the National Institute for Space Research (INPE), between june and october. Meteorological data (mean maximum temperature, relative humidity and total precipitation) were obtained from the website of the National Institute of Meteorology (INMET). During the study period there was a decrease of 15.90% of the native vegetation and simultaneously changes in the microclimate, with a 2,06 °C increase in temperature and a 25% decrease in relative humidity. The progressive pressure on native vegetation for land use and land cover caused quick changes in the natural landscape and microclimate of the region.</p> ER -
