China has reduced its desertified land by approximately 10% since 2000 through a massive reforestation campaign [1].
This effort represents one of the largest environmental interventions in history. By creating forest belts across northern China, the government aims to stabilize the ecosystem and protect critical farmland from encroaching sands.
The initiative, known as the Three-North Protective Forest Program or the "Green Great Wall," has been operational for roughly 50 years [4]. It targets arid regions bordering the Gobi and Tengger deserts, including the Ningxia Hui Autonomous Region [2, 3].
According to reported data, the reforestation drive has seen the planting of about 66 billion trees [3]. This scale of planting has contributed to an increase in the country's total forest cover by around 14% since 2000 [1]. Recent monitoring continues to track the progress of these belts, including sand-controlling projects captured in aerial photography as recently as June 30, 2025 [5].
The program utilizes millions of workers and officials to halt the spread of desert conditions. The goal is to improve ecological stability and increase forest cover as a core part of national environmental policy [2, 4].
However, the results of the campaign remain a point of debate among observers. Some reports said the campaign is successfully taming desert growth [2]. Other scientists said that despite five decades of work, the fight against desertification is not over [2].
“China has reduced its desertified land by approximately 10% since 2000”
The Green Great Wall demonstrates the scale of state-led ecological engineering in China. While the numerical increase in forest cover and the reduction of desertified land suggest a successful reversal of land degradation, the ongoing warnings from scientists indicate that reforestation alone may not be a permanent solution to the systemic pressures of aridification and climate change.
