Jordan’s Worsening Water Crisis A Warning For The World

Via Eurasia Review, a look at Jordan’s water crisis:

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 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.

In Jordan, flows in the region’s biggest river system – the Jordan-Yarmouk – have declined as a result of upstream diversion in Israel and Syria. Groundwater levels in some areas have dropped by more than 1 meter per year, and a major aquifer along Jordan’s boundary with Saudi Arabia is heavily pumped on both sides of the border.

Demand for water has climbed largely because of population growth punctuated by waves of refugees, including more than 1 million Syrian refugees in the past decade.

Extreme water scarcity and wide disparities in public water supplies are potent ingredients for conflict. Jordan’s water situation – long deemed a crisis – is now on the brink of “boiling over” into instability, said lead study author Jim Yoon, a water security and resilience scientist at Pacific Northwest National Laboratory.

“Jordan’s unique role as a bastion of peace in the region makes these findings all the more cause for concern,” said Yoon, who began work on the study as a PhD student at Stanford University.

The U.N. has committed to ensuring sustainable freshwater management and universal access to clean water and sanitation as one of its 17 sustainable development goals. But until now, analytic frameworks have been lacking, said Gorelick, who led the Jordan Water Project and its continuation, the FUSE Project (Food-water-energy for Urban Sustainable Environments).

The new predictions derive from a first-of-its-kind computer model of Jordan’s freshwater system that simulates interactions among natural processes and human behaviors. Under a range of climate and socioeconomic scenarios, the researchers quantified the effects of maintaining status quo versus introducing measures such as fixing leaky pipes, eliminating water theft, raising tariffs for big water users and reallocating a quarter of water from farms to cities.

The team’s modeling suggests efforts to simultaneously increase supply, slash demand and reform distribution are likely to deliver “exponential” improvements in national water security.

Access to Jordan’s public water supply today is highly unequal, with wealthier households and firms often supplementing rationed municipal supplies with costly deliveries from private tanker truck operators. German economist and study co-author Christian Klassert said, “Avoiding large disparities in public water supply will be necessary to avoid water stress under growing water scarcity in Jordan and regions around the world.”

The many facets of Jordan’s water crisis make it an especially valuable place to explore the impacts of individual versus simultaneous interventions, Gorelick said. Now that a model exists for this complex environment, it can be adapted with relative ease to other regions.

The single most effective step Jordan can take is to increase supply through large-scale desalination. One proposal among many Jordan has pursued to this end since the 1960s would desalinate water from the Red Sea in the south, transport freshwater north to the capital city Amman and dispose of the leftover highly saline water in the rapidly shrinking Dead Sea.

While water policy debates often present selected supply and demand interventions as opposing alternatives, the authors write, suites of interventions in both modes actually work best in concert.

“You would think that any one of these interventions would have a greater impact. But it turns out you have to do everything,” Gorelick said.

For a country whose economic output per person is less than one-tenth that of the U.S., the scale and cost of near-total reform of its water sector are particularly daunting. “In water-scarce regions where sustainability planning is most needed, it is challenging to think beyond how to distribute scarce freshwater tomorrow, next month, and to some extent, in the next several years,” Gorelick said. “It’s in these places where our long-term policy evaluations are most valuable.”
