This rapid review synthesises data from academic, policy, and NGO sources on child labour in the artisanal and small-scale mining (ASM) sector in Asia and Africa. ASM refers to small groups engaged in low-cost, low-tech, labour-intensive excavation and processing of minerals. Therefore, a clear distinction can be made between industrial and large-scale (usually licensed) mining on the one hand, and artisanal and small-scale (often unlicensed) mining on the other. Small-scale mining also includes all lower segments of mining (both non-mechanised and mechanised) that are not conventional industrial mining operations.
