Water scarcity stemming from the effects of climate change and population growth could spur large-scale migrations, spark conflict and cost some regions up to 6% of their gross domestic product, according to a new report from the World Bank.
The May 3 report sees a place for more water-storage infrastructure, such as dams; water recycling and reuse; and, where viable, desalination in many parts of the world that, in the coming years, will face potential shortages of water due to climate change, swelling populations and economic growth. But the report notes that, when proper safeguards are not put in place to manage use, these tools should be used with caution as “demand rises to meet the new level of supply.”
