Résumé:
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.
