The modern state of Ghana, formerly known as the Gold Coast, gained independence from Britain in 1961 CE, and the introduction of new mining technology meant that it once more played a major role in the international gold markets. For a while, Ghana ranked 5th in the world in terms of annual gold production.

The mining of gold in Ghana dates back at least to the 15th century, reflected in early European descriptions of the region as the Gold Coast. Gold has long been the most lucrative mining subsector, and in recent years Ghana became Africa's leading gold producer, with around 5m oz of output in 2020.

In southern Ghana, Snapir et al. applied an unsupervised classification approach on UK—Disaster Monitoring Constellation-2 (UK-DMC2) satellite data at 22 m resolution to analyze the destruction of cocoa growing areas due to illegal gold mining between 2011 and 2015. This study showed that ASGM expanded very rapidly.

The image was captured on April 30, 2020, by the Operational Land Imager (OLI) on Landsat 8. Out of 28 protected areas in southwestern Ghana, Upper Wassaw had the most mining. As of 2019, about 3.4 percent of the area had been converted for mining activities. Together with the non-governmental organization A Rocha Ghana, the …

Projects. Gold mining is a central component of Ghana's economy. An increased amount of illegal artisanal mining in recent years has led to accelerated deforestation, destruction of protected areas, and human health issues due to Mercury used during the mining process. This project addresses Sustainable Development Goal (SDG) 15 (Life on Land ...

Undoubtedly, some of this African gold was also used in Western gold coins. African gold was indeed so famous worldwide that a Spanish map of 1375 represents the king of Mali holding a gold nugget (Bibliothèque Nationale de France, Paris). When Mossi raids destroyed the Mali empire, the rising Songhai empire relied on the same resources. Gold ...
