Three-North Shelterbelt Programme
China's “Great Green Wall” is officially called the Three-North Shelterbelt Programme, launched in 1978. It is a massive afforestation programme across northern China (spanning three northern regions) aimed at reducing desertification, controlling sandstorms and preventing soil erosion. The programme is scheduled for completion around 2050 and represents one of the largest ecological restoration efforts in human history.
Key Drivers of Desertification in Northern China
- Rapid expansion of the Gobi Desert threatening agricultural land and settlements.
- Increasing desertification due to drought, overgrazing, deforestation and unsustainable farming.
- Frequent dust and sandstorms affecting northern China including Beijing, causing health and economic damage.
- Soil erosion reducing agricultural productivity across vast areas.
Straw Checkerboard Method
- Straw arranged in square grids over sand dunes
- Stabilises shifting sand effectively
- Reduces wind erosion significantly
- Helps vegetation establish roots
- Low-cost and indigenous technique
Afforestation & Shelterbelts
- Large-scale tree and shrub plantation
- Restoration of degraded and arid land
- Creation of shelterbelts blocking desert winds
- Species adapted to arid conditions planted
- Community participation mobilised
Key Outcomes of the Great Green Wall
- Desertified land reduced by about 10% since 2000 across project areas.
- Severely desertified land declined by over 40% — a remarkable ecological turnaround.
- Approximately 500,000 sq. km of forests created across northern China.
- Forest cover in project areas increased from 5% (1978) to 14% (2022).
- Expansion of the Gobi Desert slowed significantly in recent decades.
- Improved vegetation cover and reduction in frequency of sandstorm events.
India's Desertification Challenge
- ~30% of India's land is degraded
- Rajasthan, Gujarat, Haryana affected
- Thar Desert expansion concerns
- LDN target under UNCCD commitments
Applicable Lessons
- Strengthen afforestation in arid regions
- Promote sustainable grazing management
- Improve watershed management
- Community participation is essential
- Integrate with climate adaptation plans
- Biodiversity in Plantations — Avoid monoculture; promote mixed species plantations for long-term ecological resilience.
- Climate Adaptation — Select drought-resistant, climate-resilient species for afforestation.
- Long-term Monitoring — Invest in satellite-based monitoring and maintenance systems.
- Water Management — Develop efficient water supply systems for plantation maintenance in arid zones.
- Community Ownership — Ensure local community participation and livelihood integration.

Which of the statements given above is/are correct?
Correct Answer: D — 1, 2 and 3
- Statement 1: Correct — The Great Green Wall is officially designated as the Three-North Shelterbelt Programme, referring to the three northern regions of China (Northeast, North, Northwest) that the programme covers.
- Statement 2: Correct — The primary objectives of the programme include reducing desertification, controlling dust and sandstorms, preventing soil erosion and restoring ecological balance across northern China.
- Statement 3: Correct — The Straw Checkerboard Method involves laying straw in square grid patterns over sand dunes to stabilise shifting sand, reduce wind erosion and create conditions for vegetation to establish roots.

Model Answer
China's Three-North Shelterbelt Programme — popularly known as the Great Green Wall — launched in 1978 is one of the world's largest and most ambitious afforestation initiatives, designed to combat the rapid expansion of the Gobi Desert, control dust storms and restore degraded ecosystems across northern China.
The programme's achievements demonstrate what sustained political commitment and scientific planning can achieve: desertified land reduced by approximately 10% since 2000, severely desertified land declining by over 40%, approximately 500,000 sq. km of forests created, and forest cover in project areas increasing from 5% (1978) to 14% (2022). Innovative techniques including the indigenous Straw Checkerboard Method for sand dune stabilisation have contributed significantly to these outcomes.
However, challenges persist: climate change continues to threaten plantation viability, water scarcity limits afforestation in ultra-arid zones, monoculture plantations raise biodiversity concerns, and long-term maintenance requires sustained investment and monitoring systems.
For India, where approximately 30% of land is degraded and the Thar Desert faces expansion pressures, key lessons include: strengthening afforestation in arid regions under green India mission, promoting sustainable land and grazing management, improving watershed management integrated with afforestation, ensuring active community participation for long-term ownership, selecting diverse drought-resilient species over monocultures, and integrating desert management with climate adaptation strategies to meet India's Land Degradation Neutrality (LDN) commitments under UNCCD.
