But there is also a more surprising culprit: a national addiction to qat, a narcotic that is incredibly water-intensive to cultivate.

If current trends continue, by 2025 the city’s projected 4.2 million inhabitants will become water refugees, forced to flee their barren home for wetter lands. In preparation, some officials have already considered relocating the capital to the coast. Others have proposed focusing on desalination and conservation to buy time.

As policymakers butt heads over the best course for Yemen, the dwindling water supply is already leading to instability: according to Al-Thawra, one of the country's leading newspapers, 70 to 80 percent of conflicts in Yemen’s rural regions are water-related. And across the country, Yemen’s Interior Ministry estimates, water- and land-related disputes result in about 4,000 deaths each year -- 35 times the number of casualties in the deadliest al Qaeda attack in the country’s history.
