Su was in the grass-stripped hills tending his hungry goats. He doesn't know much about the goings-on in Beijing anyway, having never traveled further than Fengning's county seat, about 25 kilometers away. Few people think of China as a desert nation, yet it is among the world's largest. An estimated 110 million people suffer firsthand from the impacts of desertification and, by official reports, another 2,500 sq km turns to desert each year. This is nothing new, of course.
Experts argue over the reasons and consequences, but all agree that Chinese deserts are on the move.
Sand from the distant Gobi threatens even Beijing, which some scientists say could be silted over within a few years. Dunes forming just 70 km from the capital may be drifting south at 20-25 km a year. Conservative estimates say 3 km a year. And despite massive spending on land reclamation and replanting, China is falling behind. In the northwest, where the biggest problems lie, desertification has escalated from 1,560 sq km annually in the 1970s to 2,100-2,400 sq km in the 1990s.
