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。2050年全球淡水需求量將增加兩倍，如果不采取節水措施，淡水供應將有極大壓力。氣候委員會的一份氣候報告稱，經濟發展導致全球變暖，加劇了亞洲在水資源、洪水災害、食品安全、醫療健康、產業發展及生態系統等多方面危機。亞洲面臨的水危機正不斷加劇。20世紀初，國際上就有19世紀爭煤、20世紀爭石油、21世紀爭水的說法。 第47屆聯合國大會更是將每年的3月22日定為“世界水日”，號召世界各國對全球普遍存在的淡水資源緊缺問題引起高度警覺。預計到2025年，全世界將有近1/3（23億）的人口缺水，40多個國家和地區受影響。

We do find that the lessening strategy can reduce the serious risk of water stress in Asia.我們的確發現，緩解策略能降低亞洲水壓力的嚴重風險。

主句中的do表示強調。在英語句子中，我們經常用do,does,did來對謂語動詞進行強調。用于表示強調的do可以有時態的變化，但其后的動詞要用原形。

每年的3月22日是世界水日（WorId Water Day）。1993年1月18日，第四十七屆聯合國大會做出決議，根據聯合國環境與發展會議通過的《21世紀議程》第十八章所提出的建議，確定每年的3月22日為“世界水日”。其旨在推動對水資源進行綜合性統籌規劃和管理，加強水資源保護，解決日益嚴峻的淡水短缺問題，開展廣泛的宣傳以提高公眾對開發和保護水資源的認識。

在中國，每年的3月22日至28日為“中國水周”(1994年以前為7月1日至7日)。1991年起，我國還將每年5月的第二周作為城市節約用水宣傳周。“中國水周”的設立是為了進一步提高全社會關心水、愛惜水、保護水和水憂患的意識，促進水資源的開發、利用、保護和管理。
