DEGRADAÇÃO AMBIENTAL DECORRENTE DO USO E OCUPAÇÃO DO SOLO NO MUNICÍPIO DE JUNCO DO SERIDÓ, PB

Abstract

Land use and degradation in northeastern Brazil is a problem that cannot be thought of and understood with facts that occur due to water deficiency and/or poverty, but rather in a process of historical occupation due to a capitalist and commercial expansion with European origin and in the Brazilian socioeconomic context. In the municipality of Junco do Seridó, the study area of the present study, the use of land was first given by the use of the binomial cattle and cotton and that over the years there have been new occupations such as mineral extraction and polyculture. The present work sought to interpret the environmental conditions and land use in order to understand the erosion processes caused by the modification of natural morphodynamics through anthropic interventions. The research was based on the theoretical basis of consolidated authors on the theme, in addition to field tripes and surveys in search of primary and secondary data for the development of maps of geology, slope, soil, rainfall and land use.Therefore, analysis of all these data together with certain theoretical references, it was important to have an understanding of the morphodynamics of the area and the erosive processes caused by the degradation and modification of the landscape, realizing that much of the area is degraded by activities that leave the soil fully exposed and subject to erosive processes as identified in the field. Therefore, the use of geocartographic data and the understanding of land use served to diagnose the area through morphodynamics; and, identify aspects and areas that may occur soil erosion, can be used in the future for the environmental planning of the municipality, if it is of public interest and desire.
