Abstract

The general objective of this study is to investigate the effects of land use in forest fragments in the basin of the river Corumbataí (SP). We will use methods of remote sensing (by means of classification of satellite images) and geographical information systems on ground cover, structured interviews and research in databases for the collection and organization of data on land use. For this study, the types of cover are related to the materials which occupy the surface of the ground, such as water, forest and plantation. The use of the land is related to socioeconomic factors, which can determine the conservation or degradation of the forest fragments. The analysis of the results will be based on the correlation between a series of variables which represent the variation or not in the conservation of forest fragments and the indicators of land use occurring in the period 1985 to 2000. With this study we hope for discussion and comparison of the systems of production which use advanced technologies, as is the case with sugarcane, and traditional systems, as is the case of slaughter cattle in the region of the study.
