China\u2019s Great Green Wall (officially the Three-North Shelterbelt Program or Three-North Protective Forest Program) is a massive, multi-decade ecological engineering project launched in 1978 and planned to run until 2050. <\/strong><\/p>\n\n\n\n

It aims to combat desertification, reduce sandstorms and soil erosion, protect farmland, and increase forest cover across northern China (Northwest, North, and Northeast regions), covering about 4\u20134.5 million km\u00b2\u2014nearly half the country\u2019s land area.<\/p>\n\n\n\n

It is not a single continuous wall of trees, but a network of shelterbelts, forest patches, shrublands, and grasslands forming protective barriers around deserts (including the Taklamakan and Gobi), along roads, canals, fields, and settlements.<\/strong><\/p>\n\n\n\n

The program combines engineering, biological, and technological approaches, adapted to local conditions (rainfall, soil, wind, water availability). Work is done in phases and focuses on \u201cedge-locking\u201d deserts rather than greening the entire interior.<\/p>\n\n\n\n

In short, the Great Green Wall works by systematically stabilizing sand first, then establishing hardy vegetation with targeted water support and long-term management, creating living barriers that slow desert advance and gradually improve local ecosystems. It relies on massive state coordination, adaptive local techniques, and sustained effort over decades.<\/p>\n\n\n\n

China\u2019s decades-long tree- and shrub-planting campaign around the Taklamakan Desert (part of the broader Three-North Shelterbelt Program, or \u201cGreat Green Wall\u201d) has helped turn the desert\u2019s margins into a measurable carbon sink, according to satellite-based research published in early 2026.<\/strong><\/p>\n\n\n\n

The Taklamakan (also spelled Taklimakan)<\/strong>, in northwestern China\u2019s Xinjiang region<\/strong>, is one of Earth\u2019s largest and driest deserts\u2014roughly 337,000 km\u00b2 (about the size of Germany or slightly larger than Montana), often called a \u201cbiological void\u201d<\/strong> or \u201cSea of Death\u201d<\/strong> due to its hyper-arid conditions, shifting dunes, and historically minimal vegetation.<\/p>\n\n\n\n

China began large-scale afforestation efforts in 1978 primarily to halt desert expansion, reduce sandstorms, stabilize dunes, protect farmland\/infrastructure, and increase northern forest cover (with goals tied to broader national and UN forest targets).<\/p>\n\n\n\n

In late 2024, authorities announced completion of a continuous ~3,046 km (about 1,892-mile) green belt of trees and shrubs encircling the desert, alongside plantings along the Tarim Desert Highway.<\/p>\n\n\n\n

Tens of billions of trees have been planted across northern China as part of the wider program (figures around 66 billion are commonly cited for the north overall).<\/p>\n\n\n\n

A 2026 study in the Proceedings of the National Academy of Sciences (PNAS), led by researchers including King-Fai Li (UC Riverside) and involving collaborators linked to NASA data and other institutions, analyzed multi-year satellite observations (NASA\u2019s Orbiting Carbon Observatory for CO\u2082 and MODIS for vegetation\/greenness\/fluorescence) plus related models.<\/p>\n\n\n\n
