Herders reined in by government

For thousands of years, Mongolia's Dukha ethnic minority have depended on their reindeer herds to survive the bitter winters. However, they say their nomadic way of life is now threatened by new government restrictions introduced on environmental grounds.

The Dukha spend the winter in snow-covered mountain forests where temperatures plunge as low as-50 C.

Just a few dozen such families remain, sleeping in tarpaulin tents beside their tethered animals.
