Fishermen in Nagapattinam's deltaic coast, specifically in Vellapallam, Pushpavanam, and Vanavan Mahadevi, face a unique challenge as their shorelines are sinking due to a 'silky clay' soil. This geological phenomenon, attributed to sediment discharge from the Vennar Basin and shallow sea gradients, creates a quagmire that hinders boat launching and retrieval. Residents, reliant on fishing, incur costs for tractor services to manage their boats, impacting their livelihoods and earnings.
