ENVIRONMENTAL STATE AND DEGREES OF SUSTAINABILITY OF THE RIVER BASIN OF CARMO-RN, BRAZIL
Anthropogenization of the landscape; hydrographic basin; semi-arid potiguar.
The anthropogenic process of the landscape has as its main genesis factor the fixation of new uses and activities in the landscapes, thus resulting in the establishment of new logics in the functioning of landscape structures. As a result, there are, in many cases, completely altered landscapes, with indications of serious damages in the fulfillment of the system's functions. The countryside landscape is one of many other landscapes in the Brazilian territory to suffer from anthropogenicization, as is the case of the Rio do Carmo Hydrographic Basin (BHRC), which, located in the semi-arid Potiguar region, was also the stage for anthropogenic actions of different natures. In this scenario, Landscape Geoecology, observing the different stages of occupation and intense transformation of the systems, has greatly contributed to the optimization, recovery and preservation processes of different systems. From this, using Geoecology as a theoretical-methodological framework, this research aims to analyze the environmental status and degrees of sustainability of BHRC. For this, in order to obtain better results, the BHRC will be compartmentalized, based on the relief taxa, into 6 geoecological units, namely: Apodi-Mossoró Interplanaltic Depression, Serras and Inselbergs, Serra do Mel Plateau, Inner Tablelands, Coastal Plain , and River Plain. Once this is done, for the interpretation of the different landscape units of the basin, based on Conesa (2010), matrices of importance will be built between the relations of actions versus impact. As a result, to date, this research has carried out regional analyzes of the structuring of the landscape, which encompass the vertical and horizontal structure of the BHRC. This stage is the foundation for the local analyses, which must be carried out later, based on fieldwork.
