India has lost 35 sq km land to sea in last century: Study

A substantial expanse of Indian coastline was submerged in the last century due to rising sea levels caused by climate change, a new study has revealed.

It has found that a sea level rise of 1.20mm a year between 1878 and 1993 resulted in the loss of an estimated 16.96 sq km along the Maharashtra and Gujarat coast.

This is almost half the total area of 34.91 sq km inundated along the country’s coastline during the same period.

The study divided the country’s coastline into four stations — Mumbai, Kochi, Chennai and Visakhapatnam.

The Mumbai station comprises the Mahara-shtra and Guajrat coastline. Only the Chennai station, which includes Tamil Nadu and the southern part of Andhra Pra-desh, witnessed sea water receding.

This resulted in a net gain of 4.7 sq km of land.

“Studies have attributed sea level rise to global warming. And though studies in the past have revealed the amount of sea-level rise, the land lost to the sea has never been estimated,” said professor M Mandal from the Centre of Oceans, Rivers, Atmosphere and Land Sciences, IIT-Khara-gpur, who conducted the study published in the lastest issue of Current Science at the Indian Academy of Sciences, Bangalore.
