China’s Creeping Sandbox Minquin County, China
Trapped between two creeping deserts, the once fertile oasis of Minqin County, in northwest Gansu province, lives on borrowed time. The double whammy of a decade-long drought and the upriver diversion of water from its lifeline, the Shiyang River, have left Minqin to wither into the Tengger desert, which approaches from the southeast, and the Badain Jaran, closing in from the northwest. In total, since 1950, the deserts have swallowed up more than 100 square miles. During that same period, the population there has risen from 860,000 to more than 2 million.
As of 2004, the deserts were approaching at a rate of 10 meters per year. With more than 130 days of wind and dust each year, that rate is unlikely to slow. Faced with rapid desertification, the Chinese government has begun relocating displaced farmers, as arable land has decreased from 360 square miles to fewer than 60.
