Changes in temperature and rainfall will impact almost half of South Asia in the coming decades, reducing economic growth in one of the world's poorest regions, the World Bank said.
A World Bank report released on Thursday analyses two scenarios - "climate sensitive", based on collective action by nations to limit greenhouse gas emissions, and "carbon intensive", which assumes no action on climate change.
The report combines future changes in temperature and rainfall with household survey data linking living standards to weather conditions for the first time.
More than 800 million people now live in areas predicted to become moderate-to-severe "hotspots", or affected areas, by 2050 under the carbon intensive scenario, with India accounting for almost three quarters of them, the report said.
Moderate hotspots are areas where projected consumption spending declines by 4-8% and severe ones are where the drop exceeds 8%.
"There seems to be some kind of correlation between climate hotspots and water stressed areas," Muthukumara Mani, a World Bank economist, said.
The World Bank's expectation of about half of India living in moderately or severely-affected areas by 2050 tallies with a federal think tank's report two weeks ago. This warned that 600 million Indians could suffer high to extreme water stress as the country faces the worst long-term water crisis in its history.
Rising temperature and changing monsoon rainfall patterns from climate change could cost India 2.8% of gross domestic product (GDP) and depress the living standards of one in every two Indians by 2050, the World Bank report said.
