                         a import{\^a}ncia ecol{\'o}gica que o Cerrado brasileiro possui 
                         e os poss{\'{\i}}veis efeitos da intensa degrada{\c{c}}{\~a}o

                         alguns dos impactos causados pela convers{\~a}o do bioma Cerrado 
                         em {\'a}reas agr{\'{\i}}colas na regi{\~a}o de Sapezal MT, que 
                         se trata de um dos polos de produ{\c{c}}{\~a}o agr{\'{\i}}cola 
                         do Pa{\'{\i}}s e passou por um intenso processo de expans{\~a}o 
                         agr{\'{\i}}cola nas {\'u}ltimas d{\'e}cadas. Para esse fim, 
                         foram utilizados ferramentas de Sensoriamento Remoto, 
                         Geotecnologias e o modelo SWAT para a an{\'a}lise da 
                         produ{\c{c}}{\~a}o de sedimentos e escoamento superficial entre 
                         1981 - 2010 na Bacia do Rio Papagaio, que abrange a maior parte da 
                         regi{\~a}o de Sapezal. Foram realizadas duas 
                         simula{\c{c}}{\~o}es, para os per{\'{\i}}odos de 1981 a 1990 e 
                         de 2001 a 2010. Foi constatada alta correla{\c{c}}{\~a}o entre 
                         os valores de escoamento superficial e produ{\c{c}}{\~a}o de 
                         sedimentos nessa {\'a}rea, que foram maiores nos locais onde 
                         houve expans{\~a}o agr{\'{\i}}cola. Por{\'e}m, as perdas de 
                         solo simuladas encontram-se dentro dos limites de toler{\^a}ncia 
                         estabelecidos pela FAO (1967). Isso indica que as 
                         altera{\c{c}}{\~o}es provocadas pela expans{\~a}o 
                         agr{\'{\i}}cola, entre 1981 e 2010, n{\~a}o causaram grandes 
                         impactos sobre os recursos h{\'{\i}}dricos e solos dessa

                         various consequences in places where it occurs, caused mainly by 
                         the intensification of erosion process. Considering the ecological 
                         importance of the Brazilian Cerrado and the possible effects of 
                         intense degradation of this biome, this study focuses on studying 
                         and measuring some of the impacts caused by the conversion of the 
                         Cerrado to agricultural areas in Sapezal - MT region, which is a 
                         center of agricultural production in the Brazil and has undergone 
                         an intense process of agricultural expansion in recent decades. 
                         Remote Sensing, Geotechnologies and the SWAT Model were used to 
                         realize this task, in order to analyze the sediment production and 
                         runoff from 1981 to 2010. Two simulations were performed, 
                         representing the following periods: 1981-1990 and 2001-2010. It 
                         was observed high correlation between the values of runoff and 
                         sediment yield in this area. These values were higher where there 
                         was agricultural expansion. However, the simulated soil losses are 
                         within the tolerances established by the FAO (1967). This 
                         indicates that the changes caused by agricultural expansion 
                         between 1981 and 2010 did not have major impacts on water 
                         resources and soils of this region.",
