Resumen
The environmental problems caused by the indiscriminate use of natural resources
are increasingly evident and result in losses of both natural and social nature. Therefore, It’s
needed to create mechanisms that minimize and / or solve the problems caused by the use of
those resources, in which environmental planning studies are an instrument to be used in this
process. The watershed, in turn, has been adopted as a basic planning unit, due to its systemic
character that allows an integrated analysis of the elements it composes. In order to provide
theoretical and methodological bases for environmental planning in watershed, the studies
accomplished in the light of the Geoecology of Landscape are quite efficient, through the
integrated analysis of the relationship between society and nature. In this context, the present
research aimed to delimit the geoecological units of the Upper Course of the Potengi-RN
watershed (ACBHRP-RN), which is mainly inserted in the administrative limits of the cities:
Cerro Corá/RN, São Tomé/RN and Barcelona/RN. In recent years, new economic activities
have been established in this part of the basin, a factor that highlights the need for studies that
analyze local environmental conditions and indicate efficient ways of using available natural
resources. The methodology was divided into four steps, based on the geoecological
foundations, which are: organization and event, analysis and association of data, diagnosis and
propositions. To this end, the data about the physical, environmental and socioeconomic aspects
of the study area were gathered and guided from the elaboration of charts, tables, graphs and
cartographic products on a scale of 1:250,000. The results of the analyzes evaluated the
delimitation of the geoecological units of the ACBHRP-RN: Depression with Agricultural Use,
Western Slopes of Borborema with Sources, Eastern Slopes of Borborema with Strongly Wavy
Relief, Eastern Slopes of Borborema / Cidade de Pedras, Wind Plateaus, Plateaus for
Agricultural and Mining Use, Fluvial Plain / APP; Serra de Santana / Source Areas and Polênga
River Valley. Subsequently, they were affected as potentialities and limitations related to use
of the soil in each geoecological unit, in addition to the proposition of integrated actions for use
in environmental planning projects by the social groups which work in the study area. It is
hoped that the techniques used, the materials obtained and the proposals made during the
dissipated research can contribute to a better use of the available natural resources, in order to
guarantee the balance between environmental quality and social development, besides serving
as a reference for future auxiliary works involving environmental planning in watersheds
according to the Geocology of Landscape.
