In this desert oasis where East once met West and that is home to one of the world’s greatest shrines to Buddhism, the water is disappearing.

An ancient city that once served as China’s gateway to the West, Dunhuang is now threatened by very modern demands. A dam built three decades ago to help local farming, combined with a doubling of the population, have overstressed a fragile desert hydrology that had been stable for thousands of years.
