Study: Around 50 KM of Mumbai’s Coastline Vulnerable to Sea-Level Rise and Erosion

A recent study has shown that around 50 Km of the Mumbai Metropolitan Region’s (MMR) coastline is currently very vulnerable to sea-level rise/flooding as well as coastal erosion. 

The study was published in the peer-reviewed journal Springer Nature which went on to say that the coastal vulnerability index results show that from around 187.1 Km of coastline surveyed between Mira-Bhayandar and Alibaug, 50.8 Km or around 19 per cent of the portion was deemed highly vulnerable.

Further, around 60.9 Km possessed a moderate vulnerability of sea-level rise, while 55.8 Km of the portion was classified under very low vulnerability. The researchers based this study on five geological, three physical, and four socio-economic variables.

To summarize, the study shows that portions of South Mumbai as well as the eastern suburbs are highly vulnerable to the consequences of sea-level rise.

The researchers said that these risks have increased due to a combination of unsustainable development, destruction of mangroves, as well as wetlands and other water bodies across the city between 1976 and 2015.

This study was conducted jointly by researchers from the Jawaharlal Nehru University (JNU), Delhi; Asian Institute of Technology, Thailand; Deshapran College of Teachers Education, Medinipur, West Bengal; and School of Planning and Architecture, Bhopal, Madhya Pradesh.
