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.

Mr. Amer, the farmer based here, proudly showed visitors his efforts to irrigate fruit and tomato fields using rubber tubes, instead of just funneling it through earthen ditches that allow most of the water to evaporate unused. Little hoses spray the crops with water instead of wastefully soaking them.But he also pointed out two local wells where the water is dropping at the astonishing rate of almost 60 feet a year, causing the land to subside. Nearby, sinkholes in the arid soil of his property are growing longer and deeper every year.
