China’s Great Green Wall, officially known as the Three-North Shelter Forest Program, is one of the largest—if not the largest—afforestation efforts in human history. Launched in 1978, nearly half a century ago, its primary goal has been to combat desertification in northern China and reduce the frequency and severity of dust storms originating from this region. Since its inception, billions of trees and other types of vegetation have been planted, and large areas of grasslands and farmlands have been restored across northern provinces and autonomous regions. Today, the project stretches across much of northern China, forming a green belt that extends over 4,500 km in length.
However, the results of this massive undertaking remain a subject of ongoing debate. While the Chinese government, state media, and many Chinese researchers tend to emphasize the project’s achievements—particularly the slowing of desertification, the reduction in sandstorm frequency, and increases in tree cover, grasslands, and arable land—other assessments, primarily from Western researchers and media, adopt a more critical perspective. These critiques argue that the program’s successes are limited and uneven, and they highlight a range of ecological and socio-economic challenges, some of which may have been caused or exacerbated by the project itself.
This paper aims to present both the positive evaluations and the critical perspectives on the Great Green Wall. It also seeks to highlight the major changes in implementation strategies over time, many of which were introduced in response to early shortcomings. In addition, I argue that the project exhibits certain distinctively Chinese characteristics, reflecting important aspects of China’s political culture, governance practices, ideological priorities, and its unique view of the human–nature relationship. Given its long duration, vast scale, and the diversity of regions and ecosystems it spans, China’s Great Green Wall offers a valuable case study from which important lessons can be drawn for afforestation and ecological restoration efforts in other parts of the world.
