Lagos Sand Rush Reshapes Coastline, Upends Fishermen’s Livelihoods

Thousands of dredgers haul sand from Lagos Lagoon, fueling a construction boom as concrete demand spikes, but the activity narrows channels, destroys fishing grounds, and pushes poor communities like Makoko to seek other work. Sand prices have surged, while fishermen face shrinking catches, higher fuel costs, and longer trips offshore. Regulators struggle with inconsistent enforcement and informal payments blur legality, even as scientists warn dredging destabilizes seabeds, worsens water quality, and reduces Lagos’ natural flood buffers.

UN warns of devastating impact of sand dredging on ocean floor

The UN Environment Programme (UNEP) has warned that around six billion tonnes of sand are dredged from the world's oceans each year, posing a threat to marine life and coastal communities. Sand is the second most exploited natural resource after water and is used in the production of concrete and glass. The UNEP's new analysis tool, Marine Sand Watch, monitors dredging activities using marine tracking and artificial intelligence. The scale of environmental impacts is alarming, with large vessels sterilizing the ocean floor and destroying microorganisms that fish feed on. The UNEP recommends banning sand dredging from beaches to protect coastal resilience and economies.

UN Warns: Sand Dredging Threatens Ocean Floor Sterilization

The United Nations Environment Programme (UNEP) has warned that the practice of sand dredging, which involves extracting around 6 billion tons of marine sand annually, is unsustainable and can have irreversible effects on local marine life. Sand is the second most exploited natural resource in the world, but its extraction for industries like construction is poorly regulated. Some companies remove all the sand to the bedrock, sterilizing the ocean floor and preventing life from recovering. While the global extraction rate is currently lower than the sand deposited by rivers, certain areas are experiencing a depletion of sand faster than it can be replenished. China, the Netherlands, the United States, and Belgium are among the most active countries in the sand dredging sector.
