UN calls for urgent action to prevent a 'sand crisis', including a ban on beach extraction as demand surges to 50 billion tonnes a year
A UN report has called for urgent action to avert a "sand crisis," including a ban on beach extraction as demand surges to 50 billion tonnes a year amid population growth and urbanisation.
Global consumption for use in glass, concrete and construction materials has tripled over two decades to reach 50 billion tonnes a year, or about 17 kilogrammes per person each day, it said, harming rivers and coastlines and even wiping out small islands. In the Mekong River - the longest in Southeast Asia -sand extraction was causing the delta to sink, leading to salinisation of previously fertile lands.
In some cases, this can make coastlines more vulnerable to the impact of climate change, such as more powerful storms, the report said.
