| Resumo: | The current stage of the development of global society implies significant transformations in
local landscapes. The introduction of new rationales in the structure and functioning of
landscapes has, as a result, the emergence of serious damages in all spheres of the landscape
system. In front of this scenario, Landscape Geoecology, observing the different stages of
occupation and intense transformation of the systems, has contributed greatly to the analysis of
the optimization, recovery, and preservation processes of different systems. The Rio do Carmo
Hydrographic Basin (RCHB), located in the hinterland portion of the state of Rio Grande do
Norte, has a variety of landscape units and economic activities, which significantly affect the
environmental status of the basin. From this, using Geoecology as a theoretical-methodological
guide, this research aims to analyze the environmental status and degrees of sustainability of
the RCHB. For this, in order to obtain better results, the RCHB was compartmentalized, based
on the relief taxon, into 6 geoecological units, namely: (I) Sertaneja Depression do Carmo, (II)
Mountains and Inselbergs, (III) Serra do Mel Plateau, (IV) Interiors Tabuleiros, (V) Marine
Fluvial Plain, and (VI) Fluvial Plain. For the interpretation of the environmental status, the
analyzes were carried out on a regional and local scale, which made it possible to delineate
relationships between existing actions and impacts, based on the parameters established by
Conesa (2010). As main results, we highlight the presence of an evolutionary framework with
environmental damage in the Fluvial and Marine Fluvial Plain and in the Interiors Tabuleiros,
with the main impact promoters being the mineral sector, the salt industry, and agriculture.
Based on the results, it is expected that the framework presented in this study can be used by
municipal managers to propose sustainable actions in the basin, in order to improve its
environmental status. |
