Impactos socioambientais do rompimento das bacias de contenção no parque solar de São Gonçalo do Gurgueia - PI

Abstract

The ruptures of containment and tailings dams are low probability events, but they generate great concern due to the impacts that are always associated with this type of occurrence. The area in which this study was carried out is a clear example of how the construction of a solar park has an economic, social and environmental impact. In this case, the analysis concerns the containment dams built around the solar park. In this study, we seek to evaluate and present the economic and socio- environmental impacts generated by the creation of containment basins in the Solar Park of São Gonçalo do Gurguéia-PI, in order to show proposals for measures for environmental recovery of the areas affected by the implementation of the enterprise. Through the Leopold Matrix. It was observed along the research that the enterprise has great impacts, in which the physical, biotic, and socioeconomic environment has been constantly suffering, as a change in the fluvial regime of the Gurguéia River, which is the river that supplies the municipality. They are identified as: silting up of Riacho do Macaco and Riacho da Lapa, which may lead to the Gurguéia River, with the risk of eutrophication of new bodies of water and loss of springs. In addition to totally degraded areas resulting in gullies and loss of native vegetation in addition to other negative effects. Being able to list some mitigating measures such as a plan for the revitalization of rivers and streams, regeneration of the affected areas, an environmental recovery plan, in relation to the Physical Environment, the recovery measures, in the first place, aim to minimize the erosion of soils and rocks that have not yet been disaggregated, both by the reduction of surface runoff
