China completes green belt around Taklamakan Desert
China’s completion of a 3,000 km “green belt” of vegetation around the Taklamakan Desert prompts debate over how effective such large-scale afforestation projects really are at stopping desertification, and whether gains are due to policy or shifting rainfall. Commenters contrast China’s capacity to push through megaprojects with the slower, more litigious infrastructure processes in democracies, raising trade-offs between efficiency, long-term maintenance, debt burdens, and civil liberties. The thread also situates the project alongside similar efforts like Africa’s Great Green Wall and historical U.S. shelterbelts, questioning where wealthy countries choose to invest—climate resilience and public works versus military spending and financial bailouts.
Project scale, methods, and visible effects
- Green belt around the Taklamakan took ~46 years and ~3,000 km of planting; commenters see large potential local benefits (reduced sandstorms, stabilized land).
- Some claim sandstorm days in Beijing fell from ~30/year in the 1950s to single digits after 2000, with recent uptick linked to climate change rather than failure.
- Techniques mentioned: drought-resistant species, drip irrigation, water-retention membranes, micro-topography (small hills), and solar-powered pumps; also solar/wind farms feeding China’s UHV grid.
- Satellite imagery appears to show green corridors, but it’s hard for non-experts to interpret what’s vegetation vs. river-fed agriculture.
Effectiveness, sustainability, and past failures
- Several note the project is controversial: an Economist piece reportedly questions impact (rainfall vs. planting) and long‑term sustainability.
- Historical anecdotes describe earlier Chinese tree campaigns where farmers sabotaged planting (e.g., planting trees upside down) due to water competition with crops, and “plant-a-tree” rituals with little durable impact.
- Skeptics worry about limited rainfall (<100 mm/year in parts of Taklamakan), the need for ongoing irrigation/maintenance, and the risk the state is declaring victory prematurely.
- Others argue this is a standard anti-desertification strategy and is clearly mitigating, even if not fully “reversing” desert.
Comparisons to other “green wall” and land projects
- Africa’s Great Green Wall and the US Great Plains Shelterbelt are cited as analogues, with mixed progress and concerns about monitoring, collapse risk, and maintenance.
- Some emphasize that true deserts can’t be “un-desertified” without irrigation; projects work best in degraded semi-arid areas, not hyper-arid cores.
Governance, megaprojects, and geopolitical contrast
- Long thread on how authoritarian systems can execute megaprojects with fewer procedural obstacles but at the cost of civil liberties.
- US and European infrastructure efforts (Mississippi engineering, TVA, Corps of Engineers, past subway builds) are compared to China’s approach; many see current US capacity as diminished by red tape and predatory contracting.
- Broader debate on whether China’s model (including HSR build‑out and local-government debt) is a wise long-term investment or an overleveraged, sometimes “flashy” misallocation.
Climate, priorities, and ethics
- Some propose alternative or complementary climate strategies (reforestation in wetter regions, deep-ocean wood sequestration), while others emphasize ecological risks and unintended consequences.
- Weather modification (cloud seeding) by China is noted, with regional and ethical concerns.
- Several contrast China’s large-scale ecological/infrastructure projects with US spending on wars, bank bailouts, and military power, arguing about opportunity costs and global justice.
