The study reveals that weak policies regulating artisanal and small-scale gold mining in Ghana are also responsible for the increasing environmental problems. Due to this, non-Ghanaians, particularly, Chinese immigrants, have trooped themselves into illegal small-scale mining, hence, increasing the environmental impacts of ASM in the country.
