Utilização de Zizenioid (Vetiver) para contenção do processo erosivo em área de mineração

Abstract

The sand mining activity comprises an important sector of the Brazilian economy, and also has been discussed as one of the most harmful to the environment because the extraction of mineral resources requires change almost total of the natural landscape. The activities of this sector are regulated through the environmental licensing process and, are usually, followed by a Plan of Rehabilitation of Degraded Areas. The degradation in mining areas have become a costly liability and a concern for flora, human and animal life, since the degradation of area, contaminates the waters, change the landscape, silts lakes and rivers. The insertion of Vetiver emerges as an environmental solution to reverse the degradation of the soil, through the formation of hedgerows to contain runoff, and a root system very well developed. Therefore, the aim of this project consists in the implementation of Vetiver in the mining region of Dourados/MS for the containment of sheet erosion.
