- Yangtze River and is the world's largest hydroelectric scheme
- Benefits
- 18,000MW of electricity generated
- Will supply water to the region responsible for 22% of China's GDP
- Flood protection will save lives and cut financial loses
- Navigational improvements could open up China's interior to development
- Costs
- Dammed waters will drown 100,000 hectares
- 1.9 million people will be displaced
- Pollution increases as abandoned mines and factories are flooded
- Dam failure, earthquakes and heavy rain cause serious issues
- Ecological impacts on fishing and habitats
- Case Study: China's South-North Transfer Project
- Project began in 2003 and involves building 3 canals run across the eastern, middle and western parts of China and link 4 main rivers
- Benefits
- Transfer 44.8 billion m3 per year
- Central government to pay 60% of the cost
- Water conservation, improved irrigation, pollution treatment and environmental project
- Will supply big cities like Beijing
- Costs
- Significant ecological and environmental impacts along the waterways
- Resettlement of people will be needed
- Declining water quality
- Will cost $62 billion
- Will take 50 years to complete
