Khat drinks all Yemen's water

Khat is popular in many countries of the Arabian peninsula and the Horn of Africa, but in Yemen it's a full-blown national addiction. As much as 90% of men and 1 in 4 women in Yemen are estimated to chew the leaves, storing a wad in one cheek as the khat slowly breaks down into the saliva and enters the bloodstream. (From Time)

Khat fields are typically flooded twice a month, consuming about 30% of the country's water — most of which is pumped from underground aquifers filled thousands of years ago, and replenished only very slowly by the occasional rainfall that seeps through the layers of soil and rock. A recent explosion of khat cultivation has drawn water levels down to the point where they are no longer being replenished. The option of pumping desalinated water over long pipelines from coastal plants is too expensive for such a poor country. Yemen is in real danger of becoming the world's first country to run out of water.

"You sit up discussing all your problems and think you've solved everything, but in fact you haven't done anything in the last four hours, because you've just been chewing khat and all your problems actually got worse," says Adel al-Shujaa

Despite the danger, Yemen isn't about to go cold turkey anytime soon. Not only are most of the country's leaders landowners deeply involved in khat production, the leaf may be one of the few things still holding Yemen together. Says Ashraf Al-Eryani, one of GTZ's local program officers,
"Khat plays a big role in keeping people calm, and keeping them off the streets. But it's also delaying change. It's hard to convince people to act now."
