Rise in water level may put some of India's greatest cities in the flood-risk zone, affecting a total of Thirty Six million people in the nation by 2050 - about Thirt one million more than previously thought, warns a study.

New Delhi:  Rise in water level may put some of India's greatest cities in the flood-risk zone, affecting a total of Thirty Six million people in the nation by 2050 - about Thirt one million more than previously thought, warns a study.

Worldwide, rising sea levels could within 3 decades push chronic floods to affect three hundred million people, according to the anaylsis by New Jersey-based science organisation Climate Central.

The scientists found that West Bengal and seaside Odisha are anticipated to be particularly vulnerable to floods by 2050, sililar to the city of Kolkata.

The discoveries are depend on a new digital elevation model called CoastalDEM which shows that huge number of the world's coastlines are far lower than has been commonly known and that sea level rise could affect hundreds of millions of individuals in the coming decades than previously understood. Climate Central produced the model using machine learning.

The threat is targeted in coastal Asia and will have profound economic and political consequences inside the lifetimes of individuals alive today, showed the findings of the study published in the journal Nature Communications.

As a result of heat-trapping pollution from human activities, rising sea levels could within 3 decades push chronic floods to affect  three hundred  million people

India, Bangladesh, China, Vietnam, Indonesia and Thailand are home to the most people on land projected to be below average annual coastal flood levels by 2050.

Together, those 6 nations account for roughly seventy five per cent of the  three hundred million individuals on land facing the same vulnerability at mid-century.

Over the course of the 21st century, worldwidesea levels are anticipated to rise between about 2 and 7 feet, and possibly more.

"Based on sea level projections for 2050, land currently home to three hundred  million people will fall below the elevation of an average annual coastal flood. By 2100, land now home to two hundred million people could sit permanently below the high tide line," Climate Central said.

Adaptive measures like construction of levees and alternative defences or relocation to higher ground  might reduce these dangers.+
