the artisanal and the small-scale miner. We distinguish between artisanal and small-scale mining. 'Artisanal' as used in this paper refers to unorganized mining activity that does not make use of sophisticated machinery, whereas 'small-scale' is used in the context of organized miners that may not necessarily use sophisticated machinery but have a higher revenue turnover.
Areas identified as gold mining in the land cover classification model were further differentiated into two categories: large-scale, industrial mining and small-scale, artisanal mining. Industrial mining operations within the study period (2005–2019) were assumed to have a significant change in elevation because of the nature of the mining activities.
large and small-scale mining How do large and small scale mining coexist? Artisanal and Small‐Scale Mining (ASM) can be traced back to ancient history in regions where specific geological conditions made mining possible, which is why it has been traditionally carried out by rural communities as their main economic activity or as part of their diversified production systems.
