Natural vulnerability to loss of soil of the micro-watershed of the Carnaíba de Dentro river, southwest of the semi-arid region of bahia

Abstract

This research aimed to classify classify the degree of natural vulnerability to soil loss in the Carnaíba de Dentro river basin (BA), indicating the prevalence of morphogenesis/pedogenesis balance processes. The study area is located in the regional context of the southwest of the Brazilian Semiarid. Geotechnologies were used as a technique of collection, storage, treatment, spatial analysis and representation of the data obtained, resulting in vulnerability to soil loss of the Carnaíba de Dentro microbasin (BA). It was concluded balance between the pedogenesis/morphogenesis, since the Moderately Stable/Vulnerable environment had a higher incidence on Carnaíba de Dentro (BA) watershed, contradicting the hypothesis of the prevalence of morphogenesis processes, mostly present throughout Brazilian semiarid. Thus, from the data and information obtained, it was possible to provide subsidies for a better direction in the elaboration of public policies for the Carnaíba de Dentro (BA) microbasin.
