Stone Quarries Boom in Western Ghats After Sand Mining Ban
In Kerala, India, a ban on river sand mining to protect the environment has led to a big increase in stone quarries in the Western Ghats.
The ban was put in place to stop the harmful effects of sand mining, like lowering groundwater levels and disrupting streams.
But instead of using river sand, people started using manufactured sand (M-sand) made from crushing rocks.
This has led to more quarrying in the Western Ghats, which is a very important and biodiverse area.
The study found that many quarries have grown a lot, especially near protected areas.
This growth is causing problems like loud noises, dust, and vibrations that harm wildlife and people living nearby.
Experts say that the rules for quarrying need to be stricter, especially in sensitive areas, to protect the environment.
The ban on river sand mining in Kerala led to a boom in stone quarrying in the Western Ghats for manufactured sand (M-sand).
A study found 355 operational quarries, with 72 near protected areas, expanding significantly from 2011 to 2021.
Quarrying activities produce loud noises, dust, and vibrations, harming wildlife and local communities.
Experts call for stricter regulations and better enforcement to protect ecologically sensitive zones.
Alternatives to sand, like offshore sand deposits and industrial by-products, are suggested to reduce quarrying.
