Mineração de areia em Sapopema - PR: impactos ambientais e proposta de recuperação de área degradada

Abstract

The construction sector has shown a significant growth in the last years, leading to a greater demand of aggregates among them the sand. The impacts caused by the mining processes affect mainly the landscape, since it consists of the removal of the soil and the vegetation of the place to have access to the sandstone. With the closure of the area due to resource depletion or economic impracticability of the extraction, it is inevitable and necessary to survey the impacts that occur in the extraction area and to develop mitigating measures. In this way, the present work presents the monitoring of the sediment movement with the use of cuttings, the physical characterization of the soil, the evaluation of the environmental impacts resulting from the extraction of sand, its effects on the landscape and proposals of techniques for its mitigation. With the help of Checklist and field visits to monitor the behavior of sediments on site, this work seeks to identify impacts and classify them as to their degree of influence on landscape transformation, and present mitigation and remediation proposals for those which had greater influence on the process of landscape transformation.
