Skyrocketing demand, combined with unfettered mining to meet it, is creating the perfect recipe for shortages. Plentiful evidence strongly suggests that sand is becoming increasingly scarce in many regions.Sand and gravel are now the most-extracted materials in the world, exceeding fossil fuels and biomass (measured by weight). Sand is a key ingredient for concrete, roads, glass and electronics.
The negative consequences of overexploiting sand are felt in poorer regions where sand is mined. Extensive sand extraction physically alters rivers and coastal ecosystems, increases suspended sediments and causes erosionAs long as national regulations are lightly enforced, harmful effects will continue to occur. We believe that the international community needs to develop a global strategy for sand governance, along with global and regional sand budgets. It is time to treat sand like a resource, on a par with clean air, biodiversity and other natural endowments that nations seek to manage for the future.
