Core Achievement of the Three-North Protective Forest Program
Since its launch in 1978, China’s Three-North Protective Forest Program—commonly called the “Green Great Wall”—has deployed millions of workers to install “straw checkerboards” across the Kubuqi, Mu Us and other northern deserts. The method involves arranging forearm-length sticks in a grid, then planting saplings at each square’s center, with irrigation supplying water to the seedlings. The lattice stabilizes shifting dunes, allowing vegetation to take root and reducing wind-driven sandstorms.
Background & Context
Desertification in northern China accelerated in the late 20th century due to drought, overgrazing and intensive farming. The area of desertified land peaked in 2000. State media report that since that peak the region has lost more than 1,000 km² (400 mi²) of desert each year, a trend the government attributes to the Green Great Wall’s interventions.
Data & Statistics
- Overall desertified land has contracted by roughly 10 % since 2000, according to long-term monitoring by Zhu Jiaojun’s team at the Institute of Applied Ecology, Chinese Academy of Sciences.
- Areas classified as severely or extremely desertified have fallen by over 40 %.
- Forest cover in the program’s jurisdiction rose from about 5 % in 1978 to 14 % in 2022.
- Cumulative forested area now totals 500,000 km² (200,000 mi²), roughly half of China’s landmass.
- An estimated 300 million rural laborers have participated, primarily on a paid, part-time basis.
On-the-Ground Reports
Sixty-year-old desert-control worker Yin Yuzhen described early conditions as “very lonely,” with sand so thick that visibility was limited to a few meters. She recalled, “Even the passing of a bird across the sky made me happy.” Today, Yin says she can see “the sun, the green in the distance, the road,” reflecting the visible transformation of the landscape. She and her husband now tend the checkerboards from dawn to noon, assisted by their children and occasional volunteers.
Official Statements & Responses
- “The broad significance of the Three-North Program is not only the scale of restoration, but the long-term political commitment behind it.” — Barron Joseph Orr, chief scientist, U.N. Convention to Combat Desertification.
- “The achievement of desertification combat is due to people’s hard work and a bit of luck with climate.” — Zhu Jiaojun, scientist, Institute of Applied Ecology, Chinese Academy of Sciences.
- “Efforts to combat desertification and restore forests should be linked to local livelihoods, so communities do not see economic development and ecological protection as an either-or choice.” — Zhao Zhong, founder, Green Camel Bell (environmental advocacy group in Gansu province).
Criticism & Ongoing Challenges
Scientists caution that the gains hinge on sustained investment and careful management. Zhu Jiaojun identified the principal risk: “how conservation can be sustained if the scale of human intervention and investment is reduced.” He labeled this the “biggest challenge.” Orr added that restored dry-land ecosystems can become increasingly self-sustaining, but long-term monitoring of water availability and soil health remains essential.
Conflicting Reports & Gaps
All cited sources present a consistent picture of declining desertified area and expanding forest cover. No contradictory statistics were found, but the literature lacks detailed projections of future land-use trends and the socioeconomic impacts on the 300 million workers involved.
