Coastal sand mining, whether legal or illegal, poses one of the biggest threats to our environment. Analyze the impact of sand mining along the Indian coasts, citing specific examples.
In short
Coastal sand mining, legal or illegal, erodes beaches, flattens protective dunes, salinises aquifers and destroys fisher livelihoods, while illegal mineral trade cheats the exchequer. At Alappad in Kerala's Kollam district, mineral sand mining has eaten away much of the land, sparking the Save Alappad campaign of 2018-19.

Coastal erosion
At Alappad in Kerala's Kollam district, decades of mineral sand mining have eaten away much of the land between sea and backwater, sparking the Save Alappad campaign of 2018-19.
Dunes and aquifers
Dunes buffered Tamil Nadu villages during the 2004 tsunami, and once mined, seawater enters aquifers and fields, as in the garnet belts of Thoothukudi and Tirunelveli.
Habitat damage
Turtle nesting beaches, intertidal fauna and estuarine fish nurseries are lost to digging and turbidity, weakening the food web that coastal fisheries depend on.
Livelihoods
Fishers lose landing beaches and catch as erosion advances, which has driven village resistance to mining in Kanyakumari.
Illegal trade
The Gagandeep Singh Bedi committee set up after Tamil Nadu halted beach mineral mining in 2013, exposed large-scale illegal extraction, while thorium-bearing monazite raised radiation and strategic concerns.
Regulation
Deepak Kumar (2012) required clearance even for small leases, CRZ 2019 bars coastal sand mining except for rare minerals, and the 2020 enforcement guidelines mandate drone and GPS tracking.
