Introduction:Sand mining is the extraction of sand through an open pit or via mining of inland dunes from oceans, river beds and beaches. Sand is an important component for construction activities. Rapidly urbanizing India is facing huge demand-supply gap, which is giving rise to unscientific sand mining.
Sand mining has negatively impacted -
1. River biodiversity such as Gangetic Dolphin and Gharial: Destruction of aquatic and riparian habitat through changes in the channel morphonology.
2. River banks/beds – causing flooding and change of river course E.g. Kerala floods.
3. Shrinking of river deltas: Mining is responsible for drop in sediment levels in rivers.
E.g. Ganges-Brahmaputra-Meghna delta has led to destruction of mangrove forests.
4. Marine ecosystem: Increased turbidity of water is harmful for organisms like coral that need sunlight. For example, Gulf of Mannar and Gulf of Kutch
5. Destruction of beaches causing loss of coastal ecosystem.
We should explore options like manufactured sand and import of sand. Moreover, there is a need to generate popular public opinion on the matter to bring about an end to this menace.
