The world’s beaches are being mined for sand for a variety of uses (aggregate in concrete, fill, beach renourishment). The practice is often very destructive and poorly managed (or unmanaged). This is a global phenomenon (Morocco, Caribbean Islands, India, South Africa and more). This theft of beach and dune sand is a direct cause of erosion along many shorelines. It is very damaging to the beach fauna and flora, ruinous to beach aesthetics, and frequently causes environmental damage to other coastal ecosystems associated with the beach such as wetlands.
Another major impact of beach sand mining is the loss of protection from storms surges associated with tropical cyclones and tsunamis. Some communities affected by the 2004 tsunami in the Indian Ocean had higher storm surges probably due to beach sand mining resulting in fatalities. Sometimes it is difficult to tell that a beach has been mined. Sand extraction becomes difficult to recognize as the beach readjusts to a new profile after a few storms. But historic accounts of beaches in the Caribbean often reveal that beaches have been narrowed considerably. Mining is particularly senseless in a time of rising sea level when sand is sorely needed as a storm energy buffer.

With competition for space is intensifying around Africa’s coastal cities as urbanization gains momentum, ports are using dredged material and reclaiming land to expand container terminal capacity.
Asia’s mania for reclaiming land from the sea spawns mounting problems.
For some, concerns over the tourism threat Cuba poses to Miami have reached the granular level.
Sand isn’t just for beaches. The tiny grains show up in many products of the industrialized world: in the glass and concrete that build cities, in detergents and cosmetics that people use daily, and in the silicon chips and solar panels of advanced technology. But sand comes from rocks that take thousands of years to erode into fine particles, and humans are using it faster than they should.
Land reclamation in the South China Sea could be damaging irreplaceable reef ecosystems, threatening the food security of millions. It’s time for a treaty, says leading scientist.
Mining for beach sand minerals poses a threat to the economic and social fabric of fishing villages along Tamil Nadu’s coast.
Seven such coral reefs are being turned into islands, with harbors and landing strips by the Chinese military, and it is destroying a rich ecological network. “It’s the worst thing that has happened to coral reefs in our lifetime.”
At least 2.5 million metric tons of the country’s magnetite were shipped to China from almost five years of controversy-ridden blacksand mining operations in the province of Cagayan, government records showed.
The environmental documentary ‘Sand Wars’ was shown at The Center for Ocean Health in Santa Cruz on Thursday, preceded by a presentation by UCSC professor Gary Griggs. As Gary Griggs and “Sand Wars” demonstrate, sand has become a valuable resource worldwide due in large part to continuous construction.
