Thirsty Plant Dries out Yemen

Even as drought kills off Yemen’s crops, farmers in villages like this one are turning increasingly to a thirsty plant called qat, the leaves of which are chewed every day by most Yemeni men (and some women) for their mild narcotic effect. The farmers have little choice: qat is the only way to make a profit.

Water scarcity afflicts much of the Middle East, but Yemen’s poverty and lawlessness make the problem more serious and harder to address, experts say. The government now supplies water once every 45 days in some urban areas, and in much of the country there is no public water supply at all. Meanwhile, the market price of water has quadrupled in the past four years, pushing more and more people to drill illegally into rapidly receding aquifers.

Unlike some other arid countries in the region, like Saudi Arabia and the United Arab Emirates, Yemen lacks the money to invest heavily in desalination plants. Even wastewater treatment has proved difficult in Yemen. The plants have been managed poorly, and some clerics have declared the reuse of wastewater to be a violation of Islamic principles.

Mr. Eryani, the water minister, takes the long view. Yemen has suffered ecological crises before and survived. The collapse of the Marib dam, for instance, led to a famine that pushed vast numbers of people to migrate abroad, and their descendants are now scattered across the Middle East.

“But that was before national borders were established,” Mr. Eryani added. “If we face a similar catastrophe now, who will allow us to move?”
