UN: Global sand supply is not keeping up with demand, threatening ecosystems

The United Nations said in a report released on Tuesday that the growing global sand demand, due to rapid urbanisation, construction and other factors, exceeds sustainable supply. This puts ecosystems and livelihoods at risk.

A report from the U.N. showed that about 50 billion tons of construction sand are used each year. The demand for this material is also expected to double in 2060 if current trends continue. This is faster than stock levels can be replenished. Environment Programme showed. The Environment Programme showed that sand is the second most-exploited natural resource after water. However, its use is not regulated and UNEP stated it was being consumed faster than geological processes can replace it.

UNEP stated that unsustainable sand mining is damaging the environment in areas which are a critical habitat for fish, turtles and birds, as well as disrupting local communities.

The report revealed that the depletion and growing demand for sand on land is driving a shift to marine dredging. Half of the dredging firms operate within Marine Protected Areas.

UNEP's report stated that sand is being extracted from natural ecosystems, and is then transformed into concrete, glass, and asphalt, instead of being used to filter water and protect shorelines against erosion.

"Sand is the first line of defense against rising sea levels, storm surges, and salinization of coastal aquifers, all of which are exacerbated by climate changes," said Pascal Peduzzi. Director of UNEP Global Resource Information Database Geneva.

UNEP said that sand mining can cause habitat loss, pollution and harm to species such as sea turtles. It also has the potential to threaten local economies by accelerating beach erosion, reducing fish stock and damaging local economies.

The report highlights the growing interest in mining magnetite, also known as "black sand", which contains valuable minerals. This is happening across many regions, including Southeast Asia and Latin America.

UNEP has called for stronger governance including national sand inventory and better recognition of the sand resource as a strategic one. They have also warned that current oversight is fragmented, despite repeated concerns. (Reporting and editing by Hugh Lawson; Olivia Le Poidevin)
