Yemen is a desert, and it’s running out of water:
“They tell us it’s because the water table is sinking so fast,” said Muhammad Hamoud Amer, a worn-looking farmer who has lost two-thirds of his peach trees to drought in the past two years. “Every year we have to drill deeper and deeper to get water.”
Drilling deeper and deeper isn’t a sustainable strategy though. It doesn’t increase the flow of water into Yemen; it just reaches deeper and deeper into the underground stock of water, the aquifer.
Yemen’s population has quadrupled in the last 50 years, to 24 million, but that’s not its only problem:
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.

Already, the lack of water is fueling tribal conflicts and insurgencies, Mr. Eryani said. Those conflicts, including a widening armed rebellion in the north and a violent separatist movement in the south, in turn make it more difficult to address the water crisis in an organized way. Many parts of the country are too dangerous for government engineers or hydrologists to venture into.
For centuries, the people of Yemen preserved traditions of water conservation:
Farmers depended mostly on rainwater collection and shallow wells. In some areas they built dams, including the great Marib dam in northern Yemen, which lasted for more than 1,000 years until it collapsed in the sixth century A.D.But traditional agriculture began to fall apart in the 1960s after Yemen was flooded with cheap foreign grain, which put many farmers out of business. Qat began replacing food crops, and in the late 1960s, motorized drills began to proliferate, allowing farmers and villagers to pump water from underground aquifers much faster than it could be replaced through natural processes. The number of drills has only grown since they were outlawed in 2002.
The popular drug, qat, comes from a particularly “thirsty” plant:
Despite the destructive effects of qat, the Yemeni government supports it, through diesel subsidies, loans and customs exemptions, Mr. Eryani said. It is illegal to import qat, and powerful growers known here as the “qat mafia” have threatened to shoot down any planes bringing in cheaper qat from abroad.
