Plano de recuperação para uma área degradada nos municípios de Barro Alto-BA e Ibititá-BA.

Abstract

In this study aimed to prepare a recovery proposal for a Permanent Preservation Area located on the border of the municipalities of Barro Alto-BA and Ibititá-BA. The study was developed following the following steps: georeferencing of the study area; general description of the area, description of the pre-degradation scenario, description of the post-degradation scenario, recovery strategy and environmental monitoring. These methodological steps were developed through bibliographic research, field visits, interviews with the local community, photo documentation, soil analysis and Environmental Impact Assessment methodologies: “Ad Hoc” and Interaction Matrix. A total of 19 environmental impacts were identified in the biotic, abiotic and anthropic environments, in addition, the abiotic environment was the one with the highest number of impacts. The future use of the area was based on access roads to the community and the revegetation with native species in the indicated areas, so that the problems of accelerated erosion in the area are solved and provide greater protection to the water body. Among the techniques indicated for the recovery of the area, the main ones were: eradication of degrading factors, isolation of the affected area, stabilization of gullies, construction of barriers inside the gullies, recomposition of the soil profile, revegetation and recovery of the vegetal cover, waterproofing of access roads, improvement in sanitation conditions. No matter how efficient and grounded are the chosen techniques, constant monitoring and verification of effectiveness are necessary, as the environment has its variations and particularities, which can make the recovery process unfeasible.
