Attitude and altitude helping to turn back the eco-clock

Radical new moves to reverse decades of environmental degradation are paying dividends in one of China's highest nature reserves, as Kang Bing and Liu Xiangrui report from Madoi county, Qinghai province.

In Machali, a "relocation village" for former herdsmen in Madoi county, the residents have quickly grown accustomed to their new lives.

The nearly 200 households comprise former herdsmen who previously lived in two townships near the head of the Yellow River in the Sanjiangyuan Nature Reserve in Golog prefecture, Qinghai province.
