ENVIRONMENTAL VULNERABILITY EVALUATION IN CAJAZEIRAS CREEK WATERSHED IN THE POTIGUAR SEMIARID - DOI 10.5216/bgg.v33i1.23632

Abstract

This article analyzes the environmental fragility in Cajazeiras Creek Watershed located in West Potiguar.The research was based on the landscape integrated conception of Tricart (1977), Bertrand (2004),Sotchava (1978), Ross (1994, 2003, 2009), Crepani (2008), Ab’Saber (1999, 1969), using geoprocessingtechniques to analyze the geosystem, focusing on the identification of environmental fragility of landscapecomponents such as climate, relief, geology, pedology, geomorphology and soil use and occupation. Theresults show that the watershed landscape has medium and high environmental fragility throughout itsarea, especially on the riverbanks, due to the areas use and occupation for farming and for Pau dos FerrosCity urban areas occupation. In this context, it is necessary, the creation of a regional policy for supportingterritorial management that considers the watershed as a planning cell, and the development of a plan forthe soil use and occupation, compatible with the environmental and social realities, considering the variousdemocratic principles.
