Artisanal and small-scale gold mining (ASGM) in Tanzania is an essential economic enterprise; it employs more than one million people and contributes to 30% of Tanzania’s total gold production. However, the use of mercury poses severe health and environmental risks, as it contaminates air, water, and soil and disproportionately harms impoverished mining communities. SWISSAID works to improve conditions in artisanal gold mines in Tanzania. In collaboration with FADev, they develop model mines that adhere to strict environmental and health standards, including reducing and eliminating the use of mercury. However, despite these efforts and Tanzania being a signatory to the Minamata Convention on Mercury, the implementation of mercury reduction measures remains under-examined at the local level. This report aims to assess the implementation of the Minamata Convention and other mercury reduction efforts in Tanzanian ASGM, with a specific focus on regions where SWISSAID operates. By drawing on insights from three model mines in the Geita and Shinyanga regions, the report outlines policy recommendations that are locally feasible, socially equitable, and environmentally sustainable.
