The Yangtze River Basin: Home to 400+ Million People

Over 400 million people—roughly one-third of China's population—live in the Yangtze River Basin. This 1.8M km² watershed (19% of China's land) generates ~45% of national GDP.

Demographic Weight

• Chongqing (municipality): 32M (upstream anchor).
• Wuhan: 13M (central hub).
• Nanjing: 9M.
• Shanghai (delta): 29M (metro).
• Chengdu (tributary Min): 21M.

Density exceeds 1,000/km² in delta; <50/km² in Tibetan headwaters.

Why So Many?

• Alluvial Fertility: 2,000+ years of rice/wheat civilization.
• Transport Artery: Navigable 2,800 km (ocean ships to Wuhan). Three Gorges Dam locks.
• Industrial Cluster: Steel (Wuhan, Chongqing), auto, electronics, petrochem, textiles.
• Water Security: Supplies 40% of China's freshwater withdrawals.

Pressures

Pollution (industrial, agricultural, plastic), sand mining, dam fragmentation (Three Gorges, 20+ mainstream dams), wetland loss (80%), climate-driven flood/drought extremes. The 1998 floods killed 4,000+, displaced 18M.

Management

Yangtze River Protection Law (2021): fishing ban (10 yr), pollution caps, ecological redlines, integrated basin governance. The basin's fate is China's fate.
