Coastal sand mining, both legal and illegal, has emerged as a severe environmental threat in India, disrupting ecological balance and livelihoods. The extraction of sand from beaches and riverbeds alters coastal geomorphology, leading to erosion, loss of protective dunes, and increased vulnerability to storms and tsunamis. For instance, in Kerala, unregulated sand mining has accelerated shoreline retreat, threatening habitats like the Vembanad Lake, a Ramsar site. Similarly, in Tamil Nadu, illegal mining in the Tamiraparani River delta has degraded estuarine ecosystems, affecting fisheries and biodiversity. Sand mining also exacerbates saline intrusion, contaminating groundwater and agricultural lands, as seen in Gujarat’s coastal districts. Additionally, it disrupts sediment flow, impacting delta formation and mangrove forests, critical for carbon sequestration and storm protection. To mitigate these impacts, stringent enforcement of environmental laws, community-based monitoring, and sustainable alternatives like manufactured sand must be prioritized. A balanced approach integrating ecological conservation with developmental needs is essential for preserving India’s coastal ecosystems.
