Análise da degradação ambiental devido à exploração do Riólito no distrito de Namaacha

Abstract

The Namaacha district has potential for developing stone extraction activities. (Rhyolite). However, the emission of dust into the environment is a problem that poses a challenge to regulatory authorities of this activity to present guidelines that aim to guarantee the environment healthy environment. This work aims to analyze environmental degradation due to the exploration of Rhyolite in the district of Namaacha. Specifically, the work will: Identify areas of rhyolite exploration in the District; describe the socio-economic impacts of Rhyolite exploration as well as map the main areas affected by degradation due to the exploration of this volcanic igneous rock. Although, the dwellings closest to the quarries are located at a greater distance at 500 meters, it is important to highlight that the pollutant dispersion radius varies from 0 to 2km, affecting the communities that are located near the Movene and Matsequenha rivers (VIEIRA et al, 2014). The Movene and Kulula quarries represent a source of pollution and water contamination of the river Movene. This contamination poses a risk to the local community, quality of life, water and human activities that are developed along the quarry area (GUALE, 2016)(TRADUÇÃO NOSSA)
