2050年世界变成这样：水资源短缺(组图)

水成为最珍贵的资源

　　Water Shortage 水资源短缺

　　Africa's rivers face dramatic change that will leave a quarter of the continent severely short of water by the middle of the century, according to a global warming study published today.

　　在今天出版的全球变暖问题研究报告称，非洲河流正面临巨变，这将导致在本世纪中叶，非洲四分之一的地区处于严重缺水状态。

　　Even modest decreases in rain in western Africa will see rivers lose as much as 80% of their water, triggering a surge of what the scientists call "water refugees".

　　即便是在西非出现降雨的适度减少，也会造成河流损失多达80%的水量，引发专家们称之为“水难民”的难民潮。

　　"In those areas where there is already a water shortage, it's going to have a devastating affect," the study says. "If you're already walking 5 km to the nearest stream to get water, by 2050, it's going to mean walking 30 km or moving your whole household closer to the water source."

　　该报告指出：“在那些水资源本来就很缺乏的地区，事情的发展将会带来灾难性的影响。如果现在需要徒步到5公里以外最近的水源地取水，到2050年就意味着要到30公里之外，或者只能搬到离水源更近的地方。”
