China's 'Green Great Wall' Controls Desert Growth, but Scientists Warn the Fight Is Not Over

China's long-term Desertification Control Program, known as the Green Great Wall, has significantly reduced desertified land in northern China since its launch in 1978. Efforts such as planting trees and using “straw checkerboards” have restored over 500,000 square kilometers of vegetation, with desertified areas decreasing by over 1,000 square kilometers annually since 2000. Progress depends on ongoing maintenance, climate conditions, and integrating ecological restoration with local livelihoods.
