Dwindling water supplies and a growing population will halve per capita water use in Jordan by the end of this century. Without intervention, few households in the arid nation will have access to even 40 liters (10.5 gallons) of piped water per person per day.
Low-income neighborhoods will be the hardest hit, with 91 percent of households receiving less than 40 liters daily for 11 consecutive months per year by 2100.
Those are among the sobering predictions of a peer-reviewed paper by an international team of 17 researchers published March 29 in Proceedings of the National Academy of Sciences.
Jordan’s deepening water crisis offers a glimpse of challenges that loom elsewhere as a result of climate change, population growth, intensifying water use, demographic shocks and heightened competition for water across boundaries, said study co-author and Stanford hydrologist Steve Gorelick, who directs the Global Freshwater Initiative at Stanford’s Woods Institute for the Environment. The World Health Organization estimates half of humanity may live in water-stressed areas by 2025, and the United Nations anticipates water scarcity could displace 700 million people by 2030.
