How critical mineral mining in East Africa is driving deforestation and threatening conservation

A new study published in Nature reveals that mining for critical minerals like cobalt and copper in sub-Saharan Africa is causing far more deforestation than the mine footprints alone. Researchers found that for every hectare cleared directly by a mine, an additional 34 hectares of forest are lost within five years due to roads, settlements, and agriculture linked to mining activity. The findings come as East Africa's mineral exports surge, with the EAC reporting a 30.7 percent increase in trade to $46.3 billion in early 2026, driven largely by copper and precious metals. The Democratic Republic of Congo, which supplies over 70 percent of global cobalt, is a focal point of this tension between economic growth and environmental damage. Experts quoted in the article call for stricter enforcement of environmental impact assessments and comprehensive cost-benefit analyses before approving new mining projects. With G7 leaders meeting to discuss cleaner critical mineral supply chains, the article raises a central question: can the region capture the economic upside of the energy transition without sacrificing its forests and communities?

This is the kind of trade off that doesn't get enough attention. Everyone wants EVs and batteries but nobody wants to talk about what it takes to get the minerals out of the ground.

Exactly. The Nature study they cite says 34 hectares of offsite loss for every hectare of direct mining. That is massive. If we don't account for that in lifecycle analysis, we are kidding ourselves about net environmental benefit.

34 to 1 is a brutal ratio. I wonder how much of that is from artisanal mining vs industrial operations. The article mentions DRC specifically but doesn't break that down. Makes a big difference for what kind of regulation actually works.

Good question. The IMF numbers in the article project $16 trillion in cumulative revenue from these minerals over 25 years. Sub Saharan Africa's share could be 10 percent. That kind of money changes incentives fast. The question is whether EIA enforcement can keep up or if we need binding supply chain rules from buyers.

The G7 angle is interesting. If they actually agree on procurement standards that require verified low deforestation sourcing, that could shift things. Otherwise it is just more talk while the mines expand.
