Resumen:
As a unit for planning purposes, to integrate water and soil, bulky for the maintenance of life,
the watershed is of fundamental importance to management and management of the
environment and natural resources. Therefore, this study aims to use the spatial distribution
and land use in the watershed of the Farinha River, observing that which expresses the
Brazilian environmental legislation. The watershed of the Farinha River is located in the
central-western state of Paraiba, it covers an area of 822.7 km ² and is bounded by the
coordinates 07° 01' 39" to 07° 16' 50" latitude and 36º 43' 41" at 37° 16' 28" longitude of
Greenwich. We used images from the Satellite Landsat-5 and the geo processing techniques,
and the integration of plans was done in the Geographic Information System Idrisi Andes
version 15.0. In order to verify compliance of the adequacy of land use, we crossed plans of
the current information of the Land Use and the Preservation Areas. Among the classes of
land use and soil, open wooded Caatinga shrub (CAAA) was more significant with 46.5% of
the area. We observed patches of anthropogenic following the shores of the Farinha River and
especially on the outskirts of cities and districts. In higher areas of the watershed, primarily in
Sierra Aba, we found a different type of vegetation. Approximately half of the land in the
basin is permanent preservation areas and restricted use.
