Kochi: A study conducted by the National Center for Ocean Information Services (INCOIS) pointed out that 15 km of coastline in the state is at risk of erosion. The study provides an insight into the vulnerability of the coastal region in several parts of the state.
The Coastal Vulnerability Index (CVI) of INCOIS pinpoints that the coastal areas of Kannur, Kochi, Alappuzha and Kasaragod districts are at high risk. They are vulnerable to coastal erosion, rise in sea level, high tidal waves, tsunamis and other natural disasters.
According to the study, 53 km of the state coastline is vulnerable, and an additional 243 km is semi-vulnerable. The researchers studied changes in sea levels and coastal areas, natural disasters and wave height.
The highly vulnerable areas should be in mind while formulating policies and projects for the coastal region, said TM Balakrishnan Nair, director and senior scientist at the INCOIS. He warned that the sea level in the state is alarmingly rising at a rate of 3 to 3.4 mm per annum.
