Holding back the sands of time (2)

Green Great Wall

In 1978, the central government launched the Green Great Wall project, aiming to create a chain of forests stretching from Xinjiang to north China's Heilongjiang province to prevent soil erosion and desertification. The project, one of the biggest artificial afforestation programs in the world, is ongoing and is expected to be completed in 2050.

For the people of Qira, preventing the sand from shifting is a matter of life and death. In Hotan, the desert has buried many ancient kingdoms, leaving the remains standing deep in the desert. Since the project was launched, a forest belt has been created and the desert has receded by more than 8 km.

Memet Simay's household was one of 446 in Qira township forced to relocate in the 1980s, although the family has since returned to the area.

"When I woke up one morning, I found I couldn't open the door because of the weight of sand that had accumulated overnight. My crops were buried too, so I had no choice but to move," he recalled.

He now grows dates in a field protected by a fence of poplar trees. Memet is responsible for looking after these "guardians", as he calls the poplars.

To remind people of the scale of desert encroachment, one large sand dune has been left in the township and has become a playground for the children.

"Growing things in the desert is not easy, and it's extremely expensive," said Qi Zhendong, director of the Qira county office of desertification prevention and control.

He was inspecting some cash crops, including dates and wolfberry trees, which are drought resistant. They were planted on the outskirts of the county last year to reduce the force of the wind-carrying sands blowing into Qira.

"If a sandstorm happened now, I wouldn't be able to see you," said Qi, standing only about 2 meters distant.

The average cost of the cash crop belt, about 5.7 km long and 100 meters wide, is about 10 yuan ($1.60) per sq m, although in some areas, the figure can reach 15 yuan.

This year, Qira county aims to build 9.3 sq km of new oases close to those that already exist. "Most of Qira's revenue is devoted to creating new oases alongside the roads the government built, digging wells and planting trees. Local people plant crops," said Qi. "We have never before put so much effort into creating new oases. We appreciate the financial support from the central government and the pairing-assistance provinces program over the past three years."

The "pairing-assistance" model, unveiled by the central government in 2010, requires 19 provinces and municipalities to support the development of Xinjiang through investment, provision of raw materials and working know how.

Experience has taught Chen of the forestry bureau that local people must be involved in, and benefit from, the program to prevent and control desertification. Without that crucial local input, the plants might easily die from a lack of attention.

"We have piloted a program of assigning care of plants and trees to local farmers. They put in the work of watering and taking care of them and when the plants are ripe, the locals can sell the produce. So they reap a financial benefit from the new oases, while Hotan benefits environmentally."

He said most of Hotan's seven counties have built new oases during the past couple of years.
