Exploiting Chaos: water management in the Middle East

A water crisis rooted in wasteful irrigation, climate change and dam-building is imperiling [the wetlands of Iraq] again.

A weakened flow into the Tigris and Euphrates rivers means that salt water from the Persian Gulf can now seep upstream into the marshes. This, coupled with farming run-off that has boosted salinity,threatens wetland wildlife, vegetation and the local Marsh Arabs who have depended on them for millennia.  The problem is partly home-made. Iraq’s irrigation methods are often wasteful, and the equipment tends to be rickety. Many farmers rely on thirsty crops such as rice. Politicians have in the past secured extra water for their upstream districts at the marshes’ expense. Reform-minded technocrats are forced to contend with deep-rooted corruption, the distracting and costly fight against the Islamic State (IS) group, and low oil prices, all of which have drained state coffers.

But other problems lie beyond Iraq’s control. For decades dams built in Syria, Turkey and Iran have swallowed up the waters of the Tigris, Euphrates and other rivers feeding the marshes. New dams due to open in Turkey, including the 1,200-megawatt Ilisu Dam, could further restrict the flow of the Tigris.

Talks over these dams have been inconclusive, partly because the Syrian and Iraqi states barely function and partly because IS has controlled swathes of the Euphrates. Turkey may be tempted to exploit its upstream position.

Climate change is taking its toll, too. Last summer temperatures of about 54°C were recorded in southern Iraq, among the hottest ever.

If only Iran, Iraq, Syria and Turkey would share their waters as amicably as the Danube countries do… Dam levels should be calibrated during wet and dry years to ensure steadier flows. Iraqi officials might also ponder novel solutions, he says, such as renting storage at the Ilisu Dam for use when needed. Yet stronger countries have exploited their advantages rather than seek compromise
