Study: Middle East May Be Extremely Water Stressed By 2040

Most of the Middle East and parts of Africa have a high probability for extreme water shortages by 2040, says a new study from the World Resources Institute, due to a combination in "changes in climate, economic development, urbanization, and population growth.

 

"The WRI gathered climate and socioeconomic data on 167 countries and ranked each for future water stress — when the demand for water exceeds the available amount — in 2020, 2030 and 2040.

 

The top six — Bahrain, Kuwait, Qatar, San Marino, Singapore, and the United Arab Emirates — remain constant while the remainder of the top 10 includes Israel, Palestine, Oman, Yemen, and Saudi Arabia in varying years.

 

“With regional violence [in the Middle East] and political turmoil commanding global attention, water may seem tangential,” WRI says in a blog post about the study.

 

But access to water may be a contributing factor in much of the political and socioeconomic instability in the region, says WRI.

 

Researchers hope that the study will provide investors, policymakers, companies, and development organizations with valid projections of global water supply and demand on a national level. 

 

Other countries that fall into the extreme category by 2040 include Spain, Greece and Turkey, while the United States, China, Australia, India, Mexico, and Peru fall into the second highest category.

 

Chile, Estonia, Namibia, and Botswana could face an especially significant increase in water stress by 2040.

Achieving a water-secure future is one of six critical goals that the world must achieve this decade in order to secure a sustainable future, WRI says in it’s mission statement.

UN Predicts Serious Water Shortages by 2030

Within 15 years, the world water supply will fall short by at least 40 percent, a United Nations report cautioned Friday. 

 

Released on World Water Day, the World Water Development Report discusses trends in water use and predicts a dwindling supply in areas like sub-Saharan Africa and Southeast Asia. 

 

The report says a handful of factors are working in concert to constrict the already-contested water supply in developing countries: unchecked population growth, urbanization and industrialization.

 

"Unless the balance between demand and finite supplies is restored, the world will face an increasingly severe global water deficit," the report says. 

Climate change can also have a negative effect on the water supply.

Temperature increases cause higher evaporation from open freshwater sources, dwindling the supply. Coastal erosion brings seawater into aquifers, forcing governments to fund expensive desalination, the report says. 

A population explosion, however, is the big culprit. 

 

By 2050, the U.N. projects the global population at 9.1 billion people. According to the report, however, the relationship between water use and population growth isn't linear. In fact, over the last few decades, the rate of demand for water is double the rate of population growth. 

 

Although the report projected with an international focus, the struggle for water hits hard at home, too.

 

A day before the U.N. released its report, California Gov. Jerry Brown rolled out a $1 billion plan to fight the historic drought plaguing the state. 

Four years into the drought, Californians face tightened water restrictions that limit when and where they can harness water supplies.
