		<abstract>The knowledge about the forms of occupation and use past and current land are essential information to the study of intense erosion, desertification, flooding, silting of water courses, among others, becoming very important in that the effects of their misuse, causing deterioration in the environment, or even extinction of a given ecosystem (ROSA, 2003). Given that the study area of this research - Basin Ribeirão Bom Jardim - Triangulo Mineiro (MG) was covered in its entirety by Cerrado natural vegetation, we have analyzed the evolution of land use given to this area by mapping performed by Brito (2001) for the period between 1964 and 1999 and in 2010 as part of this research. We conducted the identification and mapping of various categories of land use that reflect the current state of conversion of native vegetation in agricultural systems. Considering the total area of the basin, it is clear that the area occupied by agriculture increased from 45.2% (1999) to 58.6% (2010). While the area covered by natural vegetation (Cerrado) was reduced from 13.8% (1999) to 5.4% (2010). The areas occupied by reforestation were maintained (3.5%). The study of the evolution of land use showed that almost all of the cerrado, which represented two thirds of the basin, has been replaced mainly by agriculture. Therefore, one should seek to encourage sustainable agricultural development, with the adoption of management techniques that conserve the soil.</abstract>
