China’s decades-long campaign against desertification has delivered measurable ecological gains, spurred innovation in renewable energy, and transformed vast arid landscapes, though scientists caution that the scale of these efforts has also produced complex environmental trade-offs.

Data from the State Council Information Office show that more than half of China’s reclaimable desertified land is now under control. Authorities said 35.9 million hectares have been protected and 7.9 million hectares effectively restored, contributing to fewer sandstorms and improved ecological stability in areas such as the Yellow River Basin.

These results stem from long-running initiatives, including the Three-North Shelterbelt Forest Program launched in 1978, alongside strengthened legal protections for forests, grasslands and wetlands.

China’s desertification control strategy is increasingly framed around the principle of “harmonious coexistence between humanity and nature,” says a report by GlobalNewswire.

In arid regions such as the Ulan Buh Desert, researchers and local workers employ techniques including straw checkerboard sand fixation, selective planting of drought-resistant vegetation, and scientific monitoring to stabilize dunes and restore ecosystems.

The report notes that these methods not only slow land degradation but also help support local livelihoods, earning China international recognition for its ecological governance.

China has also begun integrating renewable energy development into its land rehabilitation efforts. Large-scale solar power projects are being deployed in desert areas, with solar panels serving to suppress shifting sands while generating clean energy, according to a Reuters report.

In regions such as Ningxia, agrivoltaic systems allow crops like goji berries to grow beneath solar panels, reducing evaporation and preserving soil moisture.

China plans to install up to 253 gigawatts of solar capacity between 2025 and 2030 to help rehabilitate about 7,000 square kilometers of degraded land, the Reuters report adds.

However, scientists have warned of unintended consequences. A Live Science report citing recent research found that large-scale tree-planting efforts have altered China’s water distribution. While increased vegetation has intensified the overall water cycle, it has also boosted evapotranspiration, redirecting moisture toward the Tibetan Plateau and reducing water availability in parts of eastern and northwestern China.

Researchers cautioned that this shift could worsen water stress in already arid and densely populated regions.

Taken together, government data, scientific studies, and international reporting suggest that China’s anti-desertification drive underscores both the promise and the complexity of large-scale environmental intervention combining ecological restoration and renewable energy expansion with emerging scientific challenges that will shape future sustainability planning.
