YINCHUAN, June 16 (Xinhua) — Amid the vast expanse of desert in the Shapotou scenic spot, located in northwest China's Zhongwei City, a group of students watch carefully as their tutor demonstrates the technique of paving straw checkerboard, China's remarkable method for sand control.

For these local teenagers, who were excited to receive hands-on experience in making the straw checkerboard, the desert no longer holds a monstrous image. However, for older generations, the desert once represented a life-or-death crisis, as they feared the city might be engulfed by sand.

Through persistent efforts spanning several decades, Zhongwei in the Ningxia Hui Autonomous Region, located at the southern edge of the Tengger Desert, has reclaimed 1.5 million mu (about 100,000 hectares) out of its total 1.68 million mu of desert through afforestation. This endeavor has expanded its vegetation coverage from less than 1 percent to 42 percent at present, effectively pushing back the Tengger Desert by 25 kilometers.

In addition to achieving remarkable progress in desert control, the city has leveraged its remaining 180,000 mu of desert to develop desert tourism, photovoltaic, farming and breeding industries, lifting many out of poverty and improving the livelihoods of locals.

As the World Day to Combat Desertification and Drought approaches, it's worth taking a closer look at Zhongwei's journey from battling desertification to thriving amidst the sands.

The city, through its innovative desert control and harnessing practices, stands as a microcosm of the country's ambitious Three-North Shelterbelt Forest Program (TSFP), initiated in 1978 to combat desertification. Serving as a key focal point along the shelterbelt, Zhongwei plays a crucial role as an ecological barrier for north and northwest China, as well as the upper-middle reaches of the Yellow River.

China is among the countries most severely affected by desertification, with desertified areas primarily concentrated in the northwest, north and northeast regions, collectively known as the "three-north." To combat this challenge, China has proposed transforming the TSFP into a robust and enduring "green Great Wall" and ecological security barrier across the country's north.

Bolstering 'Green Great Wall'

"When I was a primary school student, a sandstorm struck one day on my way home from school. The powerful winds blew many of my classmates into a nearby ditch, and some even lost their lives," recounted Tang Ximing, 60, a senior engineer at a state-owned forestry farm in Zhongwei.

While Ningxia is surrounded by desert on three sides, Zhongwei is the hardest-hit city, highly vulnerable to sandstorm catastrophes. In 1958, when a railway that runs through Zhongwei opened to traffic, foreign experts predicted it would be inundated by sand in less than 30 years. The railway was the country's first to run through a desert.

To protect the railway route, the city embarked on a journey of desert mitigation. Scientists at the Shapotou Desert Research and Experiment Station, part of the Northwest Institute of Eco-Environment and Resources of the Chinese Academy of Sciences, along with local residents, developed straw checkerboards to stabilize the sand and prevent dunes from shifting.

By partially burying a layer of straw into the sand, the straw "stands up" as a barrier. When connected into square-shaped grids, these straws form a sprawling "checkerboard" that effectively locks up the sand like a giant mesh. Seedlings planted within these checkerboards have significantly higher chances of survival.

Tang's life is intertwined with the desert. Once eager to escape his sand-ravaged hometown, he was assigned a job as a forestry engineer in Zhongwei after graduating from college. Embracing the challenge, he has dedicated himself to transforming his hometown.

Planting a tree in the desert is extremely challenging, even with the support of straw checkerboards, due to the shallow reach of the root system. Drawing on his experiences, Tang has crafted a steel tool that differs from regular shovels by featuring two horizontal bars at the front tip. This innovative tool enables the planting of seedling roots 50 centimeters deep into the moist sand layer.

This simple tool increases the survival rate of afforestation by 25 percent to over 85 percent. It has been widely promoted and used in afforestation projects across other regions in northern China.

Tang has also worked together with researchers to develop an enhanced version of straw checkerboards that can be mass-produced using machinery, thereby extending the service life of these sand barriers.

Tang is one of many Chinese researchers and grassroots sand-control practitioners who have committed their professional expertise, practical wisdom and strenuous efforts to fortifying the "green Great Wall."

Digging Gold from Sand

"I never expected there was such a nice-looking hotel in the middle of a desert," exclaimed Khalifa Mtumwa, a foreign student from Tanzania who visited Zhongwei, referring to a newly opened premium resort hotel in Shapotou scenic spot.

Ranked as China's top desert destination, Zhongwei has made significant strides in enhancing its desert-themed tourism industry. In addition to sightseeing, visitors can enjoy a variety of leisure activities including sand surfing, sand sliding and stargazing, among others.

In another part of the desert, a cattle ranch has been established. "It's dry and well-ventilated in the desert, therefore raising cows in the desert can reduce the incidence rate of some common diseases among cows," said Yang Fei, whose company runs the farm. He added that with a daily output of over 330 tonnes of fresh milk, the farm has become an important source of income for more than 20,000 rural households in 54 local villages.

As industries thrive in Zhongwei by harnessing the resources of the desert, the aim of the TSFP extends beyond desert control to improving livelihoods. Preliminary statistics show that the TSFP has lifted approximately 15 million people out of poverty solely through forestry and fruit cultivation.

Tang is on the brink of retirement, yet his journey is far from over. Having garnered recognition in the field of desert control, he is now sought after to assist in fighting desertification in various regions.

With a packed agenda, Tang aims to combat desertification in the Inner Mongolia Autonomous Region, address coastal sand erosion in South China, and even offer his help to Mongolia.
