Sand mining from rivers is depriving many low-lying Asian deltas of the sediment they need to maintain themselves, raising the risk of worsening land loss to sea level rise, researchers say.

Sand mining has led to deepening and widening of the Lake Poyang channel, the largest freshwater lake in China and a biodiversity reserve of exceptional importance, and to an increase in water discharge into the Yangtze River. This may have influenced the lowering of the lake's water levels, which reached a historically low level in 2008.

In India, illegal sand mining is the largest organised criminal activity in the country. Criminal gangs known as "sand mafias" plunder sand and gravel resources with impunity. Their activity generally flies under the radar, even though it generates the same level of corruption and violence as the illegal trade in wild animals.

recent study estimates that 236 million cubic metres of sand are removed from the lake very year —about 9% of the total produced by China. That makes Poyang the biggest sand mine on the planet. Researchers say sand mining is the major reason why the lake's water level has dropped dramatically in recent years.

Coastal Sand Mining (including gravel) is the general term used to define the extraction of loose, non-cohesive granular particles of geological origin with 0.05–2 mm size (sand) and 2–63 mm size (gravel) from all the environments belonging to coastal systems (i.e., beaches, dunes, bluffs, cliff, deltas, barriers, and related submerged ...
