		<abstract>Sugarcane crop cultivation has been largely expanded during the last few years in Brazil in order to meet the increasing ethanol production demand. The sustainable ethanol production is directly linked to an important land use cover change issue. Therefore, it is relevant to know the land use cover prior to the sugarcane cultivation. In this context, the present work has the objective to use remote sensing images to evaluate the direct land use cover change to sugarcane in the South-Central region of Brazil, during the crop years of 2007/08 and 2008/09. Five land use classes were defined and identified through visual image interpretation on the computer screen. For the crop year 2006/07 the greatest sugarcane expansion occurred in São Paulo and Minas Gerais states (636.8 and 120.3 thousand ha, respectively) with most changes observed over the pasture class (50.4%) in São Paulo State and over the agriculture class (78.0%) in Minas Gerais State. Form the crop year 2008/09 the greatest sugarcane expansion occurred in São Paulo (661.9 thousand ha) and Goiás (143.1 thousand ha). Over the two analyzed years a total of 991.0 thousand ha of pasture and 1.15 million ha of agricultural crops were changed to sugarcane in the South-Central region of Brazil. From this work it can be concluded that the systematic acquired remote sensing images by the Landsat and CBERS satellites allowed identify the land use classes directly changed to sugarcane during the recent and fast sugarcane cultivation expansion.</abstract>
