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 detailedsimulationsof 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 butthe climate remains unchanged—and in this way—the scholars could better identify theextentto 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 faceseverewater 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 majordriverof 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 anotableamount of regionalvariationin the effects of climate change within Asia.Climate change by itself is likely to have a moreadverseimpact on water access in China than in India,for instance,where a warming climate could produce more rain.

隨著全球人口的迅速增加和人均收入水平的提高，全球淡水資源緊缺的局面正在逐漸顯現(xiàn)。2050年全球淡水需求量將增加兩倍，如果不采取節(jié)水措施，淡水供應(yīng)將有極大壓力。氣候委員會(huì)的一份氣候報(bào)告稱，經(jīng)濟(jì)發(fā)展導(dǎo)致全球變暖，加劇了亞洲在水資源、洪水災(zāi)害、食品安全、醫(yī)療健康、產(chǎn)業(yè)發(fā)展及生態(tài)系統(tǒng)等多方面危機(jī)。亞洲面臨的水危機(jī)正不斷加劇。20世紀(jì)初，國(guó)際上就有19世紀(jì)爭(zhēng)煤、20世紀(jì)爭(zhēng)石油、21世紀(jì)爭(zhēng)水的說(shuō)法。 第47屆聯(lián)合國(guó)大會(huì)更是將每年的3月22日定為“世界水日”，號(hào)召世界各國(guó)對(duì)全球普遍存在的淡水資源緊缺問(wèn)題引起高度警覺(jué)。預(yù)計(jì)到2025年，全世界將有近1/3（23億）的人口缺水，40多個(gè)國(guó)家和地區(qū)受影響。
