They found artisanal mining accounted for 25 percent of vegetation loss in the region from 2005-2019. The natural-color image above shows a large-scale mine and several artisanal mines in the Central Region of Ghana. About 28 percent was lost to both industrial and artisanal gold mining, while 29 percent was lost to urban development. The team also calculated artisanal mining activity by year to pinpoint its rise in popularity over the past decade. This research is part of larger efforts across NASA to detect unregulated gold mining in Ghana.
