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.

Cashing in on scarcity and the high price of river sand in the open market, illegal sand-mining gangs have turned their attention to the coastal areas of Kozhikode – the second largest city and urban agglomeration in Kerala State – and supply salty sand to the construction industry.
Indian mineral sand producer Trimex Group, will invest Rs. 2,500 crore (373 million USD) on mining beach minerals at Bhavanapadu and Kalingapatnam, two coastal areas of Andhra Pradesh state, located on the southeastern coast of the country. The company proposes the mining of 10 MTPA (10 million tonnes per annum) of heavy mineral sand along with pre-concentration plant of 1,525 tonne per hour.
The Negril Chamber of Commerce has expressed outrage at what it says appears to be shady sand mining activities connected to major hotel developments in Negril and elsewhere on the North Coast.
The disappearance of the beach reflects an alarming reality: Southern Monterey Bay, Marina in particular, has the highest coastal erosion rate in the state of California. For more than 20 years, scientists have speculated about the sand mine’s contribution to that erosion rate, and a 2008 study concluded it was the primary cause. The Cemex mine in Marina is the only remaining coastal sand mine in the entire United States. Which leads to new questions.
Research shows that KwaZulu-Natal and the Eastern Cape are home to more than 200 illegal sand mining operations. Umvoti River sand is as good as gold in the construction industry. Its stellar components have placed it among the best sand in South Africa for building purposes. But this comes at a great environmental loss.
After a period of calm, the illegal sand mining in Cuu Long (Mekong) Delta’s Tien Giang province has been running rampant in recent days.
The once vast sand dunes in Sydney’s south have been farmed, trimmed down by sandmining, filmed and eroded by wind and rain. Now they face encroaching housing developments
Stretching some 67 km north to south across Jamaica, the $600m four-lane nicknamed the “Beijing highway, is the single biggest investment by the Chinese in the Caribbean. This project is also prelude of the building of a $1.5bn deep water container port on islands off the south coast ,using dredging and land reclamation to accommodate mega ships coming through the expanded Panama Canal.
After hatching and dispersing across the world’s oceans, the female leatherbacks return to their natal beaches to lay clutches of eggs in the sand. A new study offers fresh insights into their nesting choices. However, human encroachment on leatherback nesting beaches, in the form of beachfront construction and sand mining, is a major threat to the animals’ continuation as a species.
