Uso de geotecnologias no estudo dos recursos naturais da bacia do rio sucuru, sub-bacia do rio Paraíba.

Abstract

The use of geotechnology in the study of natural resources allows a greater dynamic information generation process, enabling higher productivity, real-time updates and versatility in handling the data. This study aimed to map spatially and temporally the use, land degradation, and water systems of Sucuru River basin. We used the software SPRING 5.2.7 for the digital processing of satellite images and the key of interpretation for evaluation of the types of land use, degradation levels and drainage, as well as field visits, queries to literature and public agencies, and questionnaires. It was observed that there has been a regeneration of areas that were previously characterized in very serious levels of degradation, as well as severe moderate due to reasons such as, the drought that has been hampering to farm, livestock, and tree extraction. It was also found out that the riverbank of hydrous bodies of the basin, in its most part, are in serious degradation levels, resulting from the removal of its vegetation due to the exploration of these areas for various uses. Thus, the degradation processes combined with the misuse of land and water systems of the study area had as main consequence the rural exodus, from the lack of income due to the increase of unproductive land, with so great need of government intervention in order that local communities will be able to develop economically productive activities with environmental sustainability.
