The United Nations Environment Programme (UNEP) recently released a report, Sand and Sustainability: Finding new solutions for environmental governance of global sand resources, that highlights a problem that has largely stayed under the radar: sand consumption globally has been increasing and we are extracting it at rates exceeding natural replenishment rates.
Body:
Sand and gravel are the second largest natural resources extracted and traded by volume after water, but among the least regulated. Sand is created by slow geological processes, and its distribution is not even. Desert sand, available in plenty, is not suited for construction use because it is wind-smoothed, and therefore non-adherent. While 85% to 90% of global sand demand is met from quarries, and sand and gravel pits, the 10% to 15% extracted from rivers and sea shores is a severe concern due the environmental and social impacts.
Need for sand mining:
Effects on the hydraulic structure due to rampant sand mining:
Measures needed:
Conclusion:
To help states deal with the sand mining issues, including demand supply deficit and illegal extraction, the Union Government has launched a framework prepared after intensive consultations with all stakeholders. There is a need to reduce demand to responsible levels and stop environmentally damaging practices to protect sensitive ecosystems and meet biodiversity conservation goals.
