Why Africa’s mining expansion is reshaping the fate of forests: a new warning on mining, the energy transition, and regional development

Why Africa’s Mining Expansion Is Changing the Fate of Forests: A New Warning on Mining, the Energy Transition, and Regional Development

A recent *Nature* study offers an important reminder for Africa’s resource development: the impacts of mining often extend far beyond the mine pit itself.

The research team conducted a spatial and temporal analysis of 16,627 mining clusters in sub-Saharan Africa from 2001 to 2020, combining it with 20 years of forest-cover data to estimate forest loss at two levels: first, direct deforestation caused by mine pits, tailings ponds, and waste rock piles, amounting to about 187,000 hectares; and second, additional forest loss “driven” by the areas surrounding mines. The study shows that compared with unmined areas, forest loss within 1 kilometer of mining sites rises significantly, and this effect persists for years even at greater distances.

More importantly, the study found that for every hectare of direct deforestation at a mining site, an average of about 34 hectares of forest loss outside the mine is triggered within five years, driven by agricultural expansion, settlement growth, and infrastructure construction such as roads linked to mining. The additional deforestation associated with copper and cobalt mines was especially pronounced, and these two minerals are precisely the critical minerals on which the global energy transition depends heavily.

Behind mining expansion, why does such a wider range of forest loss occur?

What makes this study truly important is that it explains the chain reaction between “mining, development, and land-use change.”

First, mining is not an isolated industrial point, but an economic activity that reshapes spatial structures. Mines require roads, transport, power supply, processing facilities, worker housing, and service networks. Once these infrastructures enter what was previously an intact forest area, they improve accessibility, alter land prices and land use, and bring formerly marginalized regions into market systems.

Second, mining often attracts an inflow of people and capital. Temporary or permanent settlements that form around mining areas bring agricultural clearing, logging, commercial services, and logistics activities. In other words, mining stimulates not only metal output, but also a broader process of local economic restructuring.

Third, in the context of the energy transition, the pace of mining expansion is accelerating. The International Energy Agency has long pointed out that the clean energy transition will significantly increase demand for copper, cobalt, lithium, and other critical minerals. For sub-Saharan Africa, this means mining is no longer just a traditional export sector, but is becoming part of the global energy industrial chain. This makes the issue more complex: can Africa participate in the supply chains of the energy transition without excessively shifting ecological costs onto local forests and communities?

What does this mean for local development?

From a development perspective, this trend is not just an environmental issue, but also an issue of productive capacity and the quality of long-term growth.

1. Impact on jobs and the local economy

Mining projects usually bring jobs in construction, transport, services, security, processing, and logistics.## Impact on Employment and Local Economies

Mining projects usually create jobs in construction, transportation, services, security, processing, and logistics. These jobs are genuinely attractive to resource-dependent regions and may become an important entry point for youth employment. However, research reminds us that if uncontrolled expansion occurs around mining areas, employment opportunities are often accompanied by land conflicts, resource competition, and the growth of the informal economy, and short-term income may not necessarily translate into long-term productivity.

2. Impact on the Industrialization Base

Mineral development is often seen as the starting point of industrialization because it can provide raw materials for smelting, materials processing, the battery industry, and manufacturing. But if mining expansion does not simultaneously improve electricity, transportation, and spatial planning, the industrial chain is likely to remain at the primary export stage. In other words, if Africa only exports ore and cannot build local processing capacity with higher added value, the development gains from resource exploitation will be greatly reduced.

3. Impact on Infrastructure and Land Use

The roads, ports, railways, and settlement expansion mentioned in the study show that mining itself changes the infrastructure layout. The question is whether this infrastructure serves broader development goals, or only a single mining site. If the road network can further connect agricultural production areas, industrial parks, and regional markets, mining may become the anchor of an integrated development corridor; but if the infrastructure only speeds the export of resources, its spillover effects on development will be clearly limited.

4. The Dual Significance for Energy Transition

Cobalt and copper are minerals for the energy transition, which means African mining is becoming deeply tied to global demand for clean energy. A key paradox emerges here: the world hopes to address climate change through a lower-carbon energy system, yet the extraction of critical minerals may worsen tropical forest loss. The challenge ahead is not whether to mine, but how to advance mining to higher standards so that it truly meets the parallel requirements of “low-carbon transition” and “nature conservation.”

Impact on Regional Development: This Is Not Just a Single-Country Issue

Mining-driven forest change often crosses administrative boundaries and affects the broader regional development landscape.

1. Regional Connectivity Will Be Redefined

Mines need roads, railways, ports, and power networks. Once these facilities are built, they often serve not only mining but also become part of regional trade channels. The study notes that mining indirectly drives the construction of ports, roads, and railways, which means mining projects may become the “anchor points” of regional infrastructure networks. In some areas, this anchor effect may help remove logistics bottlenecks between inland resource regions and coastal markets.

2. Cross-Border Supply Chains and Competition Will Intensify

Copper, cobalt, and other critical minerals are already core resources in global supply chains. As countries compete to attract mining investment, there will also be more intense competition within Africa over resources, infrastructure, and ports. In the future, whichever country can provide more stable energy, more efficient logistics, clearer regulation, and more credible environmental governance will be more likely to gain an advantage in regional mineral supply chains.### 3. Agricultural and Forest-Edge Areas Will Be Under Pressure

Population flows and land development driven by mining often squeeze surrounding agricultural and ecological spaces. For regions reliant on forest resources and smallholder economies, this shift may reshape local livelihood structures. If planning is inadequate, mining corridors may become channels of land fragmentation and ecological degradation; if governance is effective, they may also become new development axes connecting minerals, agricultural processing, and urban markets.

In the next 5 to 15 years: Where will Africa’s mining growth story go?

The signal sent by this study goes far beyond “forest loss” itself. In fact, it points to a larger judgment about the future: Africa’s resource development is entering a new stage in which governance frameworks must be reconstructed.

The first possibility: mining continues to expand, but ecological costs spill over

If mining projects remain centered on short-term output, and environmental impact assessments only calculate the mine pit itself without incorporating external effects such as surrounding agricultural expansion, road networks, and settlement growth, then forest loss will be systematically underestimated. The result will be increased resource exports, but also simultaneous rises in land degradation, community conflict, and ecological pressure.

The second possibility: mining becomes an entry point for industrial upgrading

If governments, companies, and financial institutions incorporate mining into a more comprehensive spatial planning system, and promote power, transport, processing, towns, and environmental governance in an integrated way, then mining could very well become an important starting point for industrialization. Especially in key mineral sectors such as copper and cobalt, Africa has the opportunity to gradually move up from raw material supply to processing and manufacturing.

The third possibility: green mining standards become a dividing line for investment

The study clearly recommends that external forest loss around mining areas be included in environmental impact assessments for new mining projects. The practical implication of this recommendation is that future capital will not only ask “where are the minerals,” but also “where can we achieve a low-impact, traceable, and certifiable supply chain.” For African countries, this will directly affect investment flows over the next 10 to 15 years: those that can provide stronger regulation, clearer land governance, and a more credible low-deforestation mining framework will be more likely to attract high-quality investment.

Conclusion

This study is not just a quantification of forest loss; it is more like a reminder to Africa’s resource-based growth model: future mining competition will no longer be only a competition of output, ore grade, and freight costs, but a competition of development capacity, spatial governance, and supply chain standards.

If Africa can place mining, infrastructure, energy transition, and regional connectivity on the same development map, mineral resources have the chance to transform from “export-oriented wealth” into an “industrialization fulcrum.” Conversely, if mining expansion continues at the expense of ecological externalities, resource prosperity may erode the foundations of long-term growth.In this sense, this event does indeed represent an important shift in Africa’s long-term development path: it is turning the question of “how to extract resources” into the broader issue of “how to use resources to drive modernization.” It may also become one of the key turning points in Africa’s growth story over the next decade—provided that Africa can establish a truly workable development balance between the energy transition and forest protection.
