Africa's Mining Boom Is Devouring Forests at a Staggering 34:1 Ratio

The impact radius extends far beyond the concession boundary. A 2024 study on artisanal mining in the Democratic Republic of the Congo found deforestation impacts reaching at least 5 kilometers from mine sites, as entire communities and farmlands spring up around mineral extraction points . Once a road is cut, it provides access deeper into the forest for other activities, creating a cascading cycle of loss that continues long after the initial mine opens .

Which minerals cause the worst forest loss?

The answer has shifted in recent years in a way that directly complicates climate action.

Historically, gold and coal have been the dominant drivers of mining-related deforestation. According to a World Wildlife Fund analysis, gold and coal extraction accounted for over 70% of all mining-driven tree cover loss from 2001 to 2019 . The global study published in Nature Communications in December 2025 confirmed that mining-induced deforestation is two to three times higher than previous estimates, totaling 19,765 km² of forest loss and 0.75 Pg of CO₂ emissions over the study period .

But here is where the tension sharpens: energy transition minerals—copper, cobalt, and lithium—are now causing deforestation at rates that have surpassed coal in recent data . Copper and cobalt mines in the Democratic Republic of the Congo are the most prominent hotspot . The Congo Basin rainforest, one of the world's most critical carbon sinks and biodiversity reserves, sits atop enormous deposits of the very minerals the world needs for electric vehicles, batteries, solar panels, and wind turbines.

Artisanal and small-scale mining (ASM), often informal and unrecorded, is a major piece of the puzzle. The Nature Communications study found that over half—50.29%—of global mining-related deforestation is linked to unrecorded mining activities . In the eastern DRC alone, ASM accounts for at least 6.6% of deforestation between 2001 and 2020, higher than previously estimated . Informal gold mining in Ghana and the Amazon, and artisanal cobalt digging in the DRC, all follow the same pattern: a discovery triggers a rush, settlements appear, forests fall, and the recorded mine area captures only a fraction of the destruction.

The clean energy paradox

The technologies meant to pull humanity out of the fossil fuel era demand an unprecedented supply of minerals. The International Energy Agency projects that demand for copper, cobalt, lithium, and rare earth elements will grow 40-fold by 2040 to meet net-zero targets . Africa holds a substantial share of these global reserves, and extraction is already surging.

The new research reveals the uncomfortable reality: mining for clean energy minerals is currently driving significant deforestation and carbon release at the extraction point. The Congo Basin forest stores vast quantities of carbon. When trees are cut and burned for mine infrastructure, that carbon enters the atmosphere immediately—undermining the very climate benefit the minerals are meant to create . As the Nature study documents, demand for copper and cobalt is a primary driver of the 34:1 deforestation multiplier seen across Africa .

This sustainability paradox is not theoretical. The World Economic Forum has described it plainly: mining for transition minerals can intensify land disruption, water scarcity, pollution, and biodiversity loss, while displacing communities and disrupting livelihoods . Policy frameworks often lag behind the pace of extraction, and regulations designed for mining companies’ direct footprints rarely account for the indirect deforestation that follows access roads into intact forests .

Researchers and policy analysts increasingly argue that forest conservation and mineral demand must be managed together, not as competing priorities that trade one crisis for another. Comprehensive policies would need to account for the full induced deforestation footprint of mining—roads, settlements, agricultural expansion—and require planning for off-site impacts before a concession is granted . Without this, the clean energy transition risks hollowing out the forests that do some of the heaviest lifting for carbon removal.

Beyond the numbers

The data make clear that the debate about mining and deforestation cannot stop at the mine gate. When 34 hectares of forest fall for every 1 hectare of pit, regulators, investors, and battery buyers are looking at a 35-fold undercount of the real environmental cost. The minerals essential for the energy transition come from landscapes that the transition itself is putting at greater risk.
