ABSTRACT

The appropriation of the natural environment by man establishes strategies of spatial production and organization. This work aims to perform a multitemporal analysis of land use and land cover in the last two decades in Riachao das Neves County, considering the terrain attributes and the adequacy of environmental laws. The methodology adopts remote sensing and GIS techniques and field work. The data processing can be subdivided into the following steps: (a) multitemporal analysis of agricultural expansion, (b) protected areas mapping, and (c) identification of inappropriate use of protected areas. Multitemporal analysis using ALOS-PRISM sensor with high spatial resolution for 2008 and the Landsat imagery from 1988, 1992, 1996, 2000, 2004 and 2008. The classification process was done by visual interpretation and checking of field work. Riachao das Neves has approximately 67% of the natural vegetation. There is an apparent geomorphological control on the production system. In the Depression and Valley areas, the land use is concentrated around the rivers by small farmers, mostly livestock farming, while in the Plateau areas the land use is dominated by large scale mechanized agriculture.
