Mongolia’s vast grasslands cover about three-quarters of the country, where nomadic herdsmen have maintained traditions stretching back centuries. But this world is changing – fast.

About 70% of this once verdant land has now been damaged, mostly due to overgrazing. The main culprit is the country’s estimated 27 million cashmere goats, which are farmed for their highly-prized wool.

Unlike the country’s 31 million sheep, the goats dig out and eat the roots of the grass, making re-growth much harder.

Add climate change on top, and the United Nations warns that a quarter of Mongolia’s grasslands have now turned to desert. The nation is, in fact, particularly vulnerable to rising temperatures, with a 2C increase over the past 70 years, higher than the world average.

“When I was child, I vividly remember the grasses would grow taller, and we would receive more rain,” says Batmunkh, a herder in the Dornod province. He looks after 1,000 animals, 300 of which are cashmere goats.
