Express News Service CHENNAI: With sea erosion threatening to displace them, Pulicat fishermen demanded that the State government declare Kattupalli coast as a ‘High Erosion Zone’. The tag would prevent mega projects like the one proposed by Adani Ports from using the fragile coastline. Erosion triggered by ports constructed at the southern portion of Kattupalli island is already eating into Korakuppam and Sattankuppam. Sattankuppam has decided to evacuate the entire village.  As part of their respective environmental-clearance, the ports were required to undertake ‘beach nourishment’ by dredging sand accumulated to the south of their breakwaters and depositing it on the northern side.  While beach nourishment cannot reverse or arrest erosion, it can reduce the rate of erosion.
