Water Not Wars Likely To Change Middle East Politics

Water rather than ethnic and religious conflict is likely to be the real game changer in the Middle East in the next 20 years says Center for Strategic and International Studies (CSIS) director Jon Alterman.  Writing in the Washington think tank’s  Middle East Notes and Comment , Alterman argues that the drying up of the region’s groundwater wells and decreasing water quality will push water to the top of the agenda, force widespread changes in lifestyle and strengthen a widespread sense of government failure and incompetence.

Already the Middle East is the world’s most water-starved regions with 10 of the 15 water-poorest countries located in the region. Ironically, Alterman notes that when Saudi King Abdul Aziz first invited geologists to explore his desert kingdom, he was hoping to find water rather than oil. Oil wealth has propelled urbanization, changed lifestyles in water-consuming ways and provided the funding to exploit massive underground water supplies to secure those lifestyles by, for example, achieving food self-sufficiency.

Such policies served in part to ensure the longevity of authoritarian regimes that needed to be seen to be providing standards of life people had become accustomed to with the flow of petrodollars. The Gulf states, where water if priced was heavily subsidized, rank today among the largest consumers of water per capita of the population.  As a result, conservation measures such as market-dictated pricing of water are proving to be politically contentious and potentially dangerous mechanisms which most regimes have so far shied away from.

Nonetheless, Arab regimes can no longer escape the fact that current water policies are unsustainable and that the region’s agricultural revolution if unchecked will render it dry in the not all too distant future. Saudi Arabia has drawn a first conclusion from this realization by declaring that it would phase out the growing of wheat in the kingdom by 2016.

Alterman warns that the Middle East’s wells are a finite resource that are being exploited to an extent far beyond their ability to replenish themselves. Already, wells are being dug ever deeper and producing water that is increasingly less pure. The Yemeni capital Sana’a is set to become in the next ten years the world’s first capital to run out of water. The Jordanian capital could follow Sana’a hot on its heels.

It’s a doomsday scenario: agriculture collapses and major cities are left with no water to serve their inhabitants. The fall will be harder in those parts of the Middle East that don’t have the petrodollars to fund expensive and energy-intensive desalination. More than ever, water will become political and a litmus test for already questionable government credibility. The political dividing lines would likely harden as a result of the fact that some of the Middle East’s largest agricultural water users are also among its most powerful families, including its rulers. This, Alterman notes, makes it all the more difficult to impose and enforce the changes needed to evade disaster.

Nevertheless, Alterman says, “the situation is not entirely hopeless.”  Alterman advocates reforming agricultural policies, enhancing farming methods, aggressively recycling waste water, enhancing government oversight of wells, introducing pricing regimes that would encourage conservation and investing in renovation of water supply systems. Some of those steps, governments could take without significant political risk and pain, others they are likely to see as so controversial that they could spark public expressions of disaffection.  The question is whether they recognize soon enough that they are between a rock and a hard place.

Saudi Desalination Plant Promises Cheaper Water

In a region dependent on fossil fuel-driven desalination plants, Saudi Arabia hopes to significantly reduce the cost of producing potable water from the salty waters of the Gulf with the Gulf’s first solar-powered desalination plant. If successful, the Saudi example could encourage other oil and sun-rich Gulf states, who rank among the world’s biggest carbon emitters, to reduce their emissions by building similar plants..

The solar-powered plant is being built by the King Abdulaziz City for Science and Technology (KACST), the epicenter of the kingdom’s efforts to break its puritan Islamic mould in a bid to ensure technological and economic development, and IBM, which has made water one of its key areas of focus.

“The culmination of our joint research initiatives has enabled us to radically reduce the cost of water through the development of nanotechnologies that revolutionize traditional desalination methods and renewable energy sources,” Takreem el Tohamy, IBM general manager for the Middle East and North Africa, told The National.

Traditional desalination plants in Saudi Arabia produce a cubic meter of water at a relatively high cost of $.067 to $1.47 compared to Singapore cubic meter and the United States, whose cost can be as little as $0.46 per cubic meter.

Located in Al Khafji, the solar-powered will also reduce cost by employing membranes instead of boiling processes to remove the salt from seawater, IBM and KACST said in a statement.IBM announced last year it had developed a new energy-eficient membrane that has a longer lifespan than previous materials. The Al Khafji plant will generate fresh water by pushing seawater through membranes to remove the salt. The solar component of the plant will produce the electricity needed to drive the machinery.

The project’s scale will overshadow pilot solar desalination plants that have been built in a number of Gulf countries, including a plant that opened in Abu Dhabi’s Al Gharbia region last year with a daily capacity of 68.2 cubic meters. Gulf countries have been trying to build cost-effective solar desalination plants for decades. Abu Dhabi built a plant at Umm al Nar in the 1980s, but it proved to be economically infeasible.

IBM and KACST predict the cost reduction despite the fact that the new plant will use electricity from concentrated solar technology that produces power at a cost many times higher than power stations fired by natural gas or oil. Electricity will come from concentrated photovoltaics, a technology that blends traditional photovoltaic cells with mirrors, lenses and motors to concentrate the rays of sun, thereby more than doubling the efficiency of the panels.

The technology is significantly more expensive than traditional photovoltaic cells alone but takes up less space and operates better in hot climates. The increased cost of using electricity from solar panels at Al Khafji will be offset by the vast efficiency gains of using the new membranes rather than heat to take the salt out of seawater.
