Thiruvananthapuram: The on-going construction at Vizhijnam for the International seaport plays major part in accelerating the rate of erosion on the southern tip of the state.
The north and south sides of the seaport, which is under construction by Adani group, faces the strange phenomenon: on one side uncontrollable erosion eats into the land, while sand dunes form on the other.
Breakwaters covering 3200 metre part of Vizhijam project is under construction (600 metres of breakwaters have already been raised) just as coastal area is shrinking from seawall.
Coastal areas of Panathura, Punthura, Valiathura, Cheriyathura, and Bhimapally are increasingly losing to sea storm.
The erosion of coast has become evident since 1970 after the breakwaters were raised for the fishing harbour.
The situation has worsened since Adani group started placing breakwaters and dredging the area.
Raising alarms, the sea claimed coast near Valiyathura Sea Bridge nearly disconnecting the bridge from the land.
The situation will be worsening in the wake of climate change coupled with the new phenomenon, said Environmental activist A J Vijayan.
Mining of hills for procuring rocks would negatively affect environment, he said.
Meanwhile, the areas lying to the south of Vizhinjam including Adimalathura, Pulluvila, Poovar, Puthiyathura, Kochuthura, and Pallam experience the phenomenon of giant waves.
Sand dunes formed here are unusually large in size, hampering traditional fisher folks from taking their boats to the sea.
Water logging in places along the sand dunes will lead to outbreak of infectious disease.
Earlier, a study by Dr. Swaminathan committee found dredging, breakwaters and construction of sea wall as shrinking the coastal areas.
