This research had identified the main factors which influenced the changes of the land use in the localities along of the Mogi Guaçu’s drainage basin between 1979 and 2001. This area is located in a strategic geographical region and has an important role for agricultural production the sugar cane at the state, national and international levels. Our study have followed three steps, the first one elaborated a database with the results of the Shift-Share model applied to the statistic data, collected from the Annual Agricultural Production Report in Municipal Scale, by Brazilian Institute of Geography and Statistics (IBGE). The second step have consisted in elaborating a Spatial Database with the multitemporal analysis of the land use in agricultural areas of five localities inside the drainage basin studied (Barrinha, Dumont, Jaboticabal, Pitangueiras, Santa Lúcia and Sertãozinho using satellite images of LANDSAT 2-MSS (1981); LANDSAT 5-TM (1990) and LANDSAT 7-ETM+ (2001). The integration and comparison of the results was the third step of this research, making possible the analysis of land use changes and agricultural production for the studied drainage basin. The results had evidenced that the Shift-share model and geoprocessing are complementary. In the study area the expansion of agricultural production occurred mainly by the substitution of smaller fields of non-profitable agricultural crops by a large sugarcane cultivated area and also, by more intensive agricultural use of the land.
