Water scarcity is expected to increase globally as populations boom and climate change sharpens uncertainty around the resource’s availability, according to a report by the World Bank.
The conclusion adds to a growing body of research, and it comes days before this year’s Climate Action 2016 summit in Washington, D.C. The report, titled “High and Dry: Climate Change, Water, and the Economy,” highlights the importance of water to human health, agriculture and geopolitical stability.
Water scarcity is expected to cost a swath of countries in regions such as sub-Saharan and northern Africa, the Middle East, and large parts of Asia roughly 6 percent of their gross domestic product, the report found. That’s under a scenario in which emissions continue to be released as they are today.
