What are the challenges and problems faced by the South-to-North Water Transfer Project?

First of all, the South-to-North Water Transfer Project has caused a wide range of social disputes since it was put forward. Opponents mainly think that the South-to-North Water Diversion Project is expensive, involving a large number of immigrants, and the water regulation is too small to bring economic benefits into play, while the water regulation is too large. The dry season may make the Yangtze River short of water, affect the navigation of the Yangtze River channel, deepen the salt tide in the Yangtze River estuary, and more easily lead to the natural environmental and ecological crisis in the Yangtze River basin. The impact of the "three-line" synchronous water transfer scheme under construction on the ecological environment may still exceed the imagination of domestic "experts".

Second, after the implementation of the South-to-North Water Transfer Project, the original flood storage and power generation function of the Three Gorges Project has been controversial. The simultaneous effects of the Three Gorges Project and the South-to-North Water Diversion Project may have an immeasurable impact on the middle and lower reaches of the Yangtze River (including ecology and shipping), especially in the dry season and dry season.

3. Liu Shukun, chief engineer of Institute of Hydraulics, China Academy of Water Resources and Hydropower Research, and chief engineer of Disaster and Environment Research Center, questioned that the South-to-North Water Transfer Project was due to the drought in southwest China at the beginning of 20 10. He believes that the once-in-a-century drought in southwest China should be corrected and the frequency and possibility of drought should be reassessed. "The results of these assessments will affect water conservancy dispatching, and when major water conservancy projects will start, how big the scale is and how big the impact is, they should be re-evaluated," Liu said.

4. The relocation of 330,000 people in Hubei Province and Henan Province of the Middle Route Project of South-to-North Water Transfer has brought turmoil to the lives of immigrants. Some immigrants can only buy a small piece of cultivated land because of insufficient compensation after buying the housing provided by the government. However, there are few job opportunities in resettlement places, and some people have to plan to leave their homes to work in big cities. [ 1 1]

5. The cost of the South-to-North Water Transfer Project has been higher than the existing cost of seawater desalination. At present, the lowest cost of seawater desalination is about 3 yuan, and the current cost of South-to-North Water Transfer Project is about 18 yuan. It is also reported that it has reached 18 yuan.
