A perspective by Prof. Wisdom Akpalu, Prof. Francis Atsu, Prof. Kwami Adanu, Prof. Daniel K. Twerefou, and Prof. Peter Quartey
Ghana’s illegal small-scale mining crisis, popularly known as “galamsey,” has become one of the country’s most pressing environmental, public health, and economic challenges. The widespread pollution of major rivers, destruction of forests, loss of agricultural land—including cocoa-producing areas—exposure of communities to heavy metals, and the rising costs of restoring degraded ecosystems have raised urgent questions about how Ghana can protect its natural capital while sustaining the livelihoods of communities that depend on mining.
At its core, the galamsey challenge is not only an environmental problem—it is also an economic, institutional, and governance challenge. It reflects the difficult choices facing many resource-rich countries: how to balance employment creation, poverty reduction, and mineral revenues with the protection of ecosystems that underpin long-term economic well-being.
The Real Cost of Degradation
Ghana’s rivers, forests, and fertile soils are a critical part of the country’s natural capital. They provide essential ecosystem services, including water for households, agriculture, and industry. When mining activities contaminate these resources, the costs extend far beyond the mining sites themselves:
- Public Health Risks: Heavy metal contamination, particularly from mercury and cyanide, poses serious long-term health risks to rural communities and threatens the safety of the broader food chain.
- Economic Strain on Utilities: The Ghana Water Company Limited faces rapidly rising costs to treat heavily polluted and turbid water, increasing the financial burden on households, businesses, and government.
- Threats to Agriculture: The conversion of productive cocoa farms and agricultural land into degraded mining pits threatens export revenues, rural livelihoods, and national food security.
From an environmental economics perspective, the challenge is to ensure that the private benefits of mining do not come at the expense of broader social and environmental costs. Effective policy must therefore address the incentives that drive illegal mining, strengthen accountability, and create pathways to sustainable livelihoods.
Pathways to a Durable Solution
1. Strengthening governance and institutional accountability
Mining regulations must be transparent, consistently enforced, and supported by credible monitoring systems. Communities, government agencies, traditional authorities, and mining companies all have important roles to play in protecting environmental resources.
2. Creating sustainable economic alternatives
Many people involved in galamsey are responding to limited livelihood opportunities. Policies that promote alternative rural employment, skills development, and sustainable enterprises are essential to reduce dependence on environmentally destructive activities.
3. Distinguishing livelihoods from industrialised illegal mining
Policy interventions must distinguish between poor rural youth seeking survival income and highly capitalised, mechanised syndicates operating heavy machinery in river bodies. Responsible small-scale mining should be formalised through streamlined permitting and strict environmental standards, while large-scale illegal operations should be subject to firm legal enforcement.
4. Recognising the value of natural capital
Rivers, forests, and fertile land are valuable economic assets. Their degradation represents a significant loss of national wealth. Policy decisions must account for the long-term value of ecosystems, not just the short-term revenues generated from mineral extraction.
Looking Ahead
For Ghana, the question is not whether mining should contribute to development—it already does. The question is whether mining can be governed in a way that creates lasting prosperity rather than transferring environmental costs to communities and future generations.
Researchers within the Environment for Development (EfD) network are generating rigorous evidence on how economic incentives, institutional reforms, community participation, and environmental valuation can support more effective policy choices across Africa.
