Q14.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.

Coastal sand mining, legal or illegal, severely threatens India's environment and communities.

Coastal Erosion and Geomorphology

Removes natural buffers (beaches, dunes), accelerating erosion and increasing vulnerability to storms and sea-level rise (e.g., Kerala, Goa). Disrupts natural sediment transport.

Biodiversity and Ecosystem Degradation

Destroys critical ecosystems (mangroves, intertidal zones), causing habitat loss for flora/fauna, including marine turtle nesting sites (e.g., Olive Ridleys on Odisha coast).

Groundwater Salinization

Reduced sand barriers cause seawater intrusion into freshwater aquifers, leading to groundwater salinization, impacting drinking water and agriculture (e.g., Gujarat, Tamil Nadu).

Livelihoods and Infrastructure

Negatively affects traditional fishing communities (loss of breeding grounds, reduced catch), degrades tourism (beaches), and damages vital coastal infrastructure.

Mitigating impacts requires stringent regulations, strict enforcement, and sustainable alternatives for coastal protection.
