In the last three decades, research on women and gender in artisanal and small-scale mining (ASM) has grown tremendously. The heightened scholarly interest towards women and gender in the ASM sector has mainly been attributed to the increasing participation of women in ASM activities since the early 2000s amidst the recent global commodity …
