Introduction

Sand mining along India’s coasts refers to the extraction of sand from beaches, river mouths, and estuaries to meet construction and industrial demands. While sand is essential for infrastructure, unregulated coastal sand mining has caused significant environmental, ecological, and social damage, threatening India’s fragile coastal ecosystems and livelihoods dependent on them.

Impacts of Coastal Sand Mining

·        Coastal Erosion:

o   Removal of sand destabilizes beaches and dunes, leading to shoreline erosion.

o   Example: Kollam and Alappuzha coasts in Kerala have experienced severe erosion due to indiscriminate sand mining.

·        Habitat Destruction:

o   Sand mining destroys nesting sites of turtles, birds, and disrupts mangroves and estuarine ecosystems.

o   Example: Olive Ridley turtle nesting sites in Odisha affected by loss of beach sand.

·        Salinity Intrusion:

o   Excessive sand removal exposes aquifers to seawater intrusion, degrading groundwater quality.

o   Example: Coastal Tamil Nadu and Andhra Pradesh have reported increased salinity in drinking water.

·        Fisheries Impact:

o   Mining in estuaries disturbs benthic organisms and breeding grounds for fish and prawns, impacting livelihoods.

o   Example: Fishing communities in Manavalakurichi, Tamil Nadu, protested against declining fish catches linked to beach sand mining.

·        Hydrological Disruptions:

o   Alters natural sediment flow and deposition, affecting deltas and wetlands.

o   Example: Vembanad Lake in Kerala has suffered siltation and biodiversity loss due to upstream and coastal sand mining.

·        Climate Vulnerability:

o   Degraded coastal buffers leave communities vulnerable to cyclones, storm surges, and sea-level rise.

o   Example: Damage from Cyclone Fani (2019) in Odisha was aggravated by reduced natural buffers.

Legal and Policy Challenges

• Despite Coastal Regulation Zone (CRZ) Notification and state-level bans (e.g., Kerala Protection of River Banks & Regulation of Removal of Sand Act, 2001), enforcement remains weak.
• Illegal sand mining continues, driven by the “sand mafia” and poor governance.

Conclusion

Unregulated coastal sand mining undermines India’s ecological security, livelihoods, and disaster resilience. A balance between developmental needs and environmental sustainability is crucial. Strengthening enforcement, promoting alternatives like manufactured sand (M-sand), community involvement, and strict compliance with CRZ norms are necessary to protect India’s coasts for future generations.
