Sand Sustainability – Are we running out of sand?

Sand is a key ingredient for urbanization, electronics, land-reclamation, coastal restoration and hydraulic fracturing. Sand mining has accelerated rapidly since 2000, and now rivals fossil fuels and biomass as the most exploited natural resource on earth. The demand for sand will inevitably increase as cities grow and per-capita consumption increases worldwide. However, there is currently no promising alternative to sand. Urgent, global action is necessary to prevent the looming "Tragedy of the Sand Commons".

A grand challenge of the 21st century is to build a global governance strategy for sand to avert disasters, and science is part of the equation in that.
