DIAGNÓSTICO SOCIOECONÔMICO E AMBIENTAL EM MICROBACIA HIDROGRÁFICA LOCALIZADA EM UM NÚCLEO DE DESERTIFICAÇÃO

Abstract

The human pressures on natural resources motivated by the need for survival, especially in places deterioration (such as areas threatened by desertification), generate a need of analysis that includes socioeconomic and environmental aspects. In order to analyze the socioeconomic and environmental deterioration in the Riacho do Trapiá microbasin, located in a nucleus of desertification in the state of Rio Grande do Norte - Brazil, was applied the matrix Leopold adapted. The indices calculated for deteriorating social, economic, technological, environmental and socioeconomic were 29.55%, 81.08%, 58.82%, 39.59% and 30.00% respectively. As noted the microbasin of Riacho do Trapiá is at a high deterioration process, over 50% of the affected area. The deterioration in the economic factor of 81.08% reflects the poor living conditions of the local resident. Index Terms - Microbasin, desertification, semi-arid, matrix of Leopold.
