Reactions: Pollution aggravates water scarcity problem
In 2010, nearly 1,000 sub-basins around the world were facing water shortages. But when considering not only water quantity, but also water quality, this figure rises to more than 2,500, according to a study published in Nature Communications. By 2050, the authors estimate that up to a third of sub-basins will face severe shortages of clean water, which could affect 3 billion people. Southern China, Europe, North America and Africa will be the most affected regions.
