Abstract
The present work was carried out as the objective of analyzing the susceptibility to desertification of the micro region of Ribeira do Pombal in Bahia. Currently the vegetative cover of the micro-region comprises 35% of its original formation with the largest remnants of Caatinga located in the municipalities of Itapicuru and Ribeira do Amparo. By the General Index of Environmental Degradation (IGD), the micro-region is at a fairly high level of degradation, with the highest IGD in the municipalities of Adustina and Paripiranga (0.21
本研究的目的是分析巴伊亚邦巴尔里贝拉(Ribeira do Pombal)微区沙漠化易感性。目前,微区域的植被覆盖面积占其原始面积的35%,Caatinga最大的遗迹位于Itapicuru和Ribeira do Amparo市。根据环境退化综合指数(IGD),该微区处于相当高的退化水平,其中adusstina和Paripiranga市的IGD最高(0.21
