on the environment and human health in Africa have increased significantly during the last decade. However, these studies tended to be concentrated on the effects of mining and mineral processing at national levels and in specific mining districts without taking into account the overall impact .
The most obvious impact to biodiversity from mining is the removal of vegetation, which in turn alters the availability of food and shelter for wildlife. At a broader scale, mining may impact biodiversity by changing species composition and structure.
Artisanal and small scale mining (ASM) is considered as a means to support and improve the quality of rural life, and is often the only activity that local communities have to sustain themselves. It is important to understand the nature of ASM and associated environmental effects in order to make informed decisions on the management, licensing ...

Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have ...
Impacts of Artisanal and Small-Scale Gold Mining on Water Quality in Mozambique and Zimbabwe: 10.4018/978-1-4666-9559-7.ch005: Artisanal and small scale gold mining (ASGM) is an informal economic activity. ASGM is the process of extracting gold ore from the ground in the absence of
political or environmental impacts of their actions. The differences in mode of extraction, legality of operation, quantity extracted, as well as the extractive volumes splits the mining region of Ghana into two major approaches: large-scale legal mining and small-scale illegal "galamsey" mining. Small-scale mining is carried out at an

Among the most significant environmental aspects related to artisanal and small-scale mining are deforestation, changes in landscape structure, influence over geomorphological processes and hydrological river regime, chemical pollution of soil and watercourses, influencing soil production capacity.
Small scale mining has been defined as an artisanal or small industrial form of raw material extraction. It is estimated that there are about 300 registered small-scale mining groups and they constitute a major source of employment especially for small scale gold and diamond miners, and contribute some foreign exchange to Ghana`s economy.
Sep 01, 2018· LCA results have shown that the environmental performance of mining processes can be improved by decreasing the amount of fossil fuel inputs (Burchart-Korol et al., 2016).However, in most mining LCAs, the mining system is simplified or represented as a black box and several aspects of the mining industry, such as treatment and waste handling, are often overlooked (Valdivia and Ugaya, .
Jan 24, 2017· The findings were published in the journal Environmental Research. Artisanal and small-scale gold mining offers low-skilled workers an opportunity to elevate themselves out of poverty.
