Análise bibliográfica de indicadores de desertificação no Cariri Paraibano.

Abstract

Desertification is a process of extreme soil degradation caused by the rapid loss of nutrients and vegetation cover due to different factors, and this entire process occurs only in regions with arid, semi-arid and dry sub-humid climates. There are several factors that aggravate desertification, ranging from inappropriate land use to long periods of drought. Due to the enormous impact generated by desertification across the globe and the great vulnerability of Cariri Paraibano, it is necessary to analyze the studies published in recent years in order to identify causes and similarities. From a bibliographic analysis, we sought to identify the main indicators present in desertification studies located in Cariri Paraibano, being possible to observe that most of the articles and works mainly expose the indicators of agricultural and livestock productivity, in addition to great loss of vegetation cover thanks to extractivism. Making it clear that only with the publication of works, dissemination of the process and the instruction of the producers will we be able to minimize this process of such seriousness.
