Sand Auditing for Sustainable River Sand Mining in Kerala
The increased population density, economic development through foreign remittance, and low per capita land availability have substantially increased anthropogenic pressure on the rivers of Kerala. Being short and swift-flowing, the rivers of Kerala are highly vulnerable to anthropogenic pressures. Sand mining in Kerala peaked in the early 1970s.

What Are The Negative Effects Of Sand Mining?
Nov 13, 2018Sand Mining Makes Areas More Prone to Flooding Beaches, dunes, and sandbanks act as barriers to flooding. When sand mining removes such barriers, areas near the sea or river become more prone to flooding. As a result, beachside communities in areas subjected to indiscriminate sand mining are thus more vulnerable to the forces of nature. 5.

Impacts of Sand Mining
Today, demand for sand and gravel continues to increase. Mining operators, in conjunction with cognizant resource agencies, must work to ensure that sand mining is conducted in a responsible manner. Excessive instream sand-and-gravel mining causes the degradation of rivers. Instream mining lowers the stream bottom, which may lead to bank erosion.
