Camel owner Baoyin Culu says prayers at the place where his last camel died. All of his 80 camels died due to desertification in the region.
Enlarge ImageThe problem of desertification began to receive the global recognition it warrants at the Rio Earth Summit in 1992. As a result, the United Nations Convention to Combat Desertification (UNCCD) was adopted in 1994. This week sees the largest gathering ever of high-level officials and experts on desertification in Havana, Cuba.
Sandstorms originating from the Chinese and Mongolian deserts can reach as far as Japan. Each year, volunteers from Japan come to plant trees in Western China.
Desertification is caused by a complex combination of factors. In China's Inner Mongolia and Xinjiang provinces in particular, some of the causes are clear. The huge pressures on China to feed 1.3 billion people has resulted in a doubling of grazing livestock numbers over the past 30 years. In 2002 China had 427 million head of livestock, up from just over 200 million in the early 70's. Previously arable land has also been over ploughed, loosening the topsoil.
The other major contributing factor is climate change. And while the problem is fueled principally by the consumption and driving habits of the West, Beijing is rapidly becoming a car city itself. In August of this year, the number of registered automobiles in Beijing surpassed 2 million. Streets that were once thronged with bicycles are now choked with cars. It took nearly 50 years for Beijing to move from just under 2,000 registered vehicles in 1950 to 1 million in 1998. The second million vehicle was added in only five years. As China and other nations reach for the same standard of living that the West has championed for decades, using the same destructive technologies and adding to the global emissions burden that the US in particular refuses to reduce, the impacts on our planet's fragile environment grow more severe with time's passing.
Warmer winters and less rainfall have left the fertile topsoil of Inner Mongolia even more susceptible to the strong winds that course across the area.
Goats in vegetation-starved areas must wear protective clothing to keep other desperately hungry goats from eating their hair.
The Chinese authorities have made the battle against desertification a top priority and are investing huge resources in putting it in check. There is a massive reforestation programme, a plan to lay down a "Green wall" of trees and plants stretching from Beijing to Inner Mongolia, and farmers are being urged to cut back on livestock numbers. Each year, Japan sends volunteers to plant trees in a bid to end the deserts's creep toward Beijing and the lengthening reach of the dust-laden winds.
Boy drinking unclean water. Scarcity of water has lead to unclean water being sold to local people. With the increasing drought and the rise in desertification in the area fresh drinking water has become a precious commodity.
For the poor of Inner Mongolia living close to a land turning to dust, desertification is costing lives and livelihoods. For these people, climate change isn't a chimera on the distant horizon: it's a killer at large today.
