Abstract

The Savanna’s biome was intensively occupied after governmental projects and policies as II National Developpinent Planning promoting the substitutions of natural physiognomic Savanna’s covers by modern agriculture and pastures and several negatives impacts on the environment related to intensive and rapid deforestation. One of consequences was an increase of isolated fragments from Savanna cover. The aim of this article is to present the land use maps of that basin and to quantify and spatialize the existent remainders of Savannah. They was made over Landsat ETM 7+ (2003) satellite image crossing visual and digital interpretations followed by field control. The results show 44,79% of total area is occupied by savanna fragments cover and 55,21% by pastures tends in view that the remainders are more concentrated in the northeast portion of the basin. Key words: Savanna Biome. Deforestation. Occupation. Land use.
