Earth's Unseen Hero: Sand Extraction Crisis Uncovered
12 May
Summary
- Sand is the most extracted solid material globally, crucial for development.
- Extraction rates outpace replenishment, harming ecosystems and livelihoods.
- Maldives' land reclamation project damaged coral reefs and marine habitats.
Sand, often overlooked, is the most extracted solid material on Earth, yet its overuse poses significant threats. Globally, humans extract approximately 50 billion tonnes of sand annually for construction and industry, a rate unsustainable for natural replenishment. This over-extraction endangers ecosystems, livelihoods, and the planet's natural defenses against climate change impacts.
In the Maldives, a nation highly vulnerable to sea-level rise, a land reclamation project exemplifies the risks. Sand dredged from northern atolls for a project near Malé resulted in the destruction of 200 hectares of coral reef and vital marine habitats. Environmental assessments indicated irreversible damage, despite contracts already being finalized, underscoring governance challenges in managing sand resources.
Similar devastating impacts have been observed in the Philippines and Indonesia, where sand dredging for urban development and infrastructure projects has decimated fisheries and severely reduced incomes for coastal communities. The UN urges a complete overhaul of governance processes, emphasizing the need for better data, monitoring, and stricter adherence to environmental regulations to address this growing crisis.
