                         is expected in deforested areas, these researches have raised the 
                         question that deforestation and land use may alter negatively the 
                         hydrological cycle in the Brazilian Amazon. To better understand 
                         these correlations a set of 30 meteorological stations together 
                         with the remote sensing of 64 images of satellites LANDSAT 5 and 2 
                         in northern Mato Grosso state was analyzed in a 30 years period 
                         from 1977 until 2007. This analysis encompassed a control area 
                         (preserved) characterized as the northwest of MT and another 
                         anthropogenic area along the arch of deforestation in the 
                         Brazilian highway BR -163. The IDW (Inverse Distance Weighting) 
                         method was used in a GIS and remote sensing image processing 
                         system SPRING as an interpolation tool in the treatment of 
                         rainfall data. Concomitant a climate change software (RCLIMDEX 
                         1.0) corroborated to identify changes in rainfall patterns 
                         throughout the region. Both tools indicated decrease in 
                         precipitation. The results points to a decrease of rainfall in 20 
                         meteorological stations in deforested areas and an increase in 
                         rainfall in 10 meteorological stations in preserved areas. It was 
                         also detected a land use change of more than 21% of the area in 
                         the northern part of MT state.",
