A new study led by MIT researchers takes a creative approach to modeling the effects of both climate change and economic growth on Asia.
To examine the risk of water shortages on the continent， the researchers conducted detailed simulations of many reasonable economic and climate pathways for Asia in the future， evaluating the relative effects of both pathways on water supply and demand. By studying cases in which economic change or growth continues but the climate remains unchanged—and in this way—the scholars could better identify the extent to which these factors cause water shortages.
The MIT-based team found that with no limitations in economic growth and climate change， an additional 200 million people across Asia would face severe water shortages by 2050. However， fighting climate change along the lines of the 2015 Paris Agreement would reduce by around 60 million the number of people facing severe water problems.
But even with worldwide efforts to limit climate change， there is a 50 percent chance that around 100 million people in southern and eastern Asia will experience a 50 percent increase in “water stress”.
“We do find that the lessening strategy can reduce the serious risk of water stress in Asia，” say Adam Schlosser and Xiang Gao. “But it doesn’t solve it all.”
The research team also uses models that track urban and industrial activities and their specific water-demand consequences across many smaller areas in Asia. Irrigation tends to be a major driver of water consumption， leading to limited access to water for other uses.
Overall， the researchers conclude， through the mid-21st century， economic growth contributes to an increase in water stress across the whole region， but climate change can have both positive and negative effects on water stress. The study turns up a notable amount of regional variation in the effects of climate change within Asia. Climate change by itself is likely to have a more adverse impact on water access in China than in India， for instance， where a warming climate could produce more rain.

随着全球人口的迅速增加和人均收入水平的提高，全球淡水资源紧缺的局面正在逐渐显现。2050 年全球淡水需求量将增加两倍，如果不采取节水措施，淡水供应将有极大压力。气候委员会的一份气候报告称，经济发展导致全球变暖，加剧了亚洲在水资源、洪水灾害、食品安全、医疗健康、产业发展及生态系统等多方面危机。亚洲面临的水危机正不断加剧。20世纪初，国际上就有19 世纪争煤、20世纪争石油、21世纪争水的说法。 第47届联合国大会更是将每年的3月22日定为“世界水日”，号召世界各国对全球普遍存在的淡水资源紧缺问题引起高度警觉。预计到2025年，全世界将有近1/3（23亿）的人口缺水，40多个国家和地区受影响。
