Hydrologists generally assess water scarcity by looking at a population-to-water equation that treats 1,700 cubic meters per person as the national threshold for meeting water requirements for agricultural and industrial production, energy, and the environment.〔(【引用サイトリンク】url=http://hdr.undp.org/en/media/HDR_2006_Chapter_4.pdf )〕 Availability below the threshold of 1,000 cubic meters represents a state of "water scarcity", while anything below 500 cubic meters represents a state of "absolute scarcity".〔 As of 2006, one third of all nations suffered from clean water scarcity,〔(【引用サイトリンク】url=http://www.uneca.org/awich/Water%20in%20Africa.pdf )〕 but Sub-Saharan Africa had the largest number of water-stressed countries of any other place on the planet and of an estimated 800 million people who live in Africa, 300 million live in a water stressed environment.〔(【引用サイトリンク】url=http://www.gisclimat.fr/manifestation-scientifique/conf%C3%A9rence-%E2%80%9Cwater-scarcity-africa-issues-and-challenges%E2%80%9D )〕 According to findings presented at the 2012 Conférence on "Water Scarcity in Africa: Issues and Challenges", it is estimated that by 2030, 75 million to 250 million people in Africa will be living in areas of high water stress, which will likely displace anywhere between 24 million and 700 million people as conditions become increasingly unlivable.〔 == Impact on development == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Water scarcity in Africa」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
