The total number of artisanal small-scale gold miners in Kenya may be close to 250,000, but this is on the increase as more people shift towards gold mining as a main livelihood source, due to a decline in agricultural productivity within the region.
Artisanal and small-scale mining, as the term is used in most parts of the world, has also been defined differently and so has no standard definition. According to the Cameroonian Mining Code of 2001, Article 2, artisanal mining involves all exploitations
This article is one of three synthesis reports resulting from an integrated assessment (IA) of artisanal and small-scale gold mining (ASGM) in Ghana. Given the complexities that involve multiple drivers and diverse disciplines influencing ASGM, an IA framework was used to analyze economic, social, health, and environmental data and to co-develop evidence-based responses in collaboration with ...

The future of artisanal and small-scale gold mining in Southern Ecuador remains uncertain as gold deposits become increasingly more difficult to extract and government resources are focused on larger scale investment.
An artisanal miner or small-scale miner (ASM) is a subsistence miner who is not officially employed by a mining company, but works independently, mining various minerals or panning for gold using their own resources. Small-scale mining includes enterprises or individuals that employ workers for mining, but generally using manually-intensive methods, working with hand tools.
