China completes green belt around Taklamakan Desert
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.
