Resumo: | Estuaries have very different characteristics in terms of their environmental aspects. It is
in these regions that one of the most complex ecosystems on planet Earth can be found,
the mangroves. Considered as an important biological indicator, the structure and
distribution of mangrove vegetation are affected by changes in the tidal regime,
hydrological recharge of rivers, salinity, climatic and precipitation conditions, and by
human action, the latter being the starting point for the analysis of the research, which
has as its object a cut of the estuarine part of the Potengi river basin, located in the city
of Natal. The mangrove ecosystem present in the research cut is pressured by the
advance of urban expansion. Thus, considering the use and coverage of the landscape
from a systemic perspective, from the theoretical-methodological support of Landscape
Geoecology, the general objective of the research was to identify the main
environmental impacts present in the study area, caused by the different activities
developed in the sector. estuary and its repercussions on the mangrove ecosystem,
considering the spatial organization of physical and socioeconomic aspects and its
consequences in the forms of use and occupation. The research was developed in
different phases, namely: organization and inventory, analysis, diagnosis and
proposition, containing specific actions that allowed achieving the objectives of the
work. Through bibliographic and field research, and the use of geoprocessing
techniques, a database was created in a Geographic Information System (GIS) that
allowed the elaboration of cartographic products related to the research area, such as
thematic maps and chart images. The results achieved in the research allowed the
identification of impacted areas, related to the different forms of use and occupation.
Another relevant point was the possibility of socializing and disseminating actions
already developed in the sector of the study area, with direct involvement with regard to
execution and planning, related to the propositional stage of the research. |
