The challenges in artisanal and small-scale gold mining sector.
This report series provides an in-depth analysis of the dynamics driving illegal mining in Ghana , its regional spread, and the actors profiting from it. Based on three years of field research, remote sensing analysis, interviews and desk research, part 1 examines two key case study regions—Western and Savannah—and explores how unlicensed ASGM has grown in scale, complexity, and impact. Part 2 will explore illicit gold supply chains and financial networks in more depth. In places like the Western region, satellite imagery shows dramatic increases in mining activity, with many operations occurring outside officially licensed zones. The environmental impacts are stark. Unregulated use of mercury in gold processing is harming water systems , while mining expansion is causing deforestation and loss of biodiversity. Remote sensing tools—including radar interferometry, flow accumulation analysis, and computer vision models—have been employed to track these developments and predict f...
