Peru is the second-largest copper producer in the world, with a growing Artisanal and Small-Scale Copper Mining (ASCM) sector. This project sought to increase knowledge about the reality of the sector in southern Peru to address a critical gap – including data on the number of miners and the conditions of their work. Participatory research methods were also used to foster multi-stakeholder dialogues around challenges and opportunities, to inform recommendations and further open dialogue on the sustainable development of this sector.
