Misguided environmental policy uproots Tibetan nomads
Tibetan grasslands, which feed Asias major rivers and have been a lifeline for pastoralists for thousands of years, are under increasing threat from climate change and human activitiesJane Qiu

In Madoi county in the northeastern part of the plateau the headwater region of the Yellow River wetlands are drying up and sand dunes loom over the bleak landscapeJane Qiu
Tibetan grasslands are also undergoing more subtle changes than desertification: the nutritious species preferred by livestock are being replaced by weeds, unpalatable grass varieties and poisonous plantsJane Qiu
Ongoing changes to the grasslands, such as desertification and shifts in vegetation composition, threaten the livelihood of Tibetan nomadsJane Qiu
The Chinese government attributes grassland degradation to overgrazing and has moved nearly 100,000 pastoralists off their land to newly built urban centres. Such ecological migrants are forced to sell their livestock and cannot find jobs because of a lack of education and skillsJane Qiu
Unable to fit into town life, former herders often gather and socialise in tents erected in their courtyard, reminiscent of their past lives as nomadsJane Qiu
As the Chinese government moves Tibetan herders off their land in the name of protecting grasslands, there is a rush of infrastructure construction across the plateau, such as this hotel near Lake Erling in the supposedly protected heart of the Sanjiangyuan National Nature ReserveJane Qiu
Road construction is widespread in the Sanjiangyuan reserve, including a US$1.8-billion project to build a 1,000-kilometre highway between Xining and Yushu, both in Qinghai province, which began in 2010 without the standard environment impact assessmentJane Qiu
Siling Co, a glacial lake in central Tibet, expanded by nearly half its original size between 2005 and 2014, and continues to engulf houses and pastures. The Chinese governments imposition of land privatisation and fencing policies have reduced herders mobility and made them more vulnerable to such perils of climate changeJane Qiu
Herders, such as Dolma in Dotse village in the northern Tibetan Plateau, have suffered serious livestock losses in snowstorms in recent decades. The lack of mobility and the erosion of the spirit of cooperation have compromised their ability to cope with climate change and natural disastersJane Qiu
Scientists attribute some of the rangeland changes to a changing climate. Here, at the Nagqu research station in the southern Tibet Plateau, Cui Shujuan, a PhD student at the Institute of Tibetan Plateau Research in Beijing, is studying the effects of warming on grassland biodiversityJane Qiu

In recent decades, the Tibetan grasslands have seen widespread deterioration — which the Chinese government attributes to overgrazing. In the past decade, Beijing has imposed strict limits on livestock numbers and moved nearly 100,000 nomads off their land to newly built urban centres. It claims that the policies have improved both the grassland health and the livelihoods of Tibetan nomads.
As nomads continue to be moved out of the Sanjiangyuan nature reserve in Qinghai province, there is a rush of infrastructure construction projects across the plateau — even within the reserve’s core zones where such human activity is prohibited but laws are seldom enforced. Across the plateau, miners rip apart mountain slopes and pollute streams and rivers, threatening the health of remaining villagers and their livestock.
While the Chinese government regards overgrazing as the key culprit for grassland degradation, scientists think climate change is also to blame. They are conducting experiments on the plateau to test the effects of warming and changes in precipitation patterns on plant growth and vegetation composition. Such knowledge is crucial for predicting how Tibetan grasslands will fare in the future.
This photo gallery visits the plateau, from Xining on its northeastern fringe to Lhasa, Tibet’s capital, and meets the relocated nomads who are struggling to come to terms with their new-found urban identity.
