Groundwater Use Efficiency in Nth China
Abstract
Major groundwater development in the North China Plain has been a key factor in the huge economic growth of China and the achievement of self sufficiency in food production. This has however produced major and continuing groundwater level decline and many associated problems:
- hundreds of thousands of dry wells
- sea water intrusion
- land subsidence over vast areas
- groundwater salinisation
Groundwater levels in the shallow unconfined aquifers levels have fallen from 10m up to 5om, at an average rate of 0.5m/year...
A broad range of strategies have been developed through several World bank and Peoples Republic of China (PRP) projects. This paper discusses these strategies and the huge effort that will be required to implement them.
