Major Cities Take Steps To Protect Water Resources
Faced with the threat of water shortages, Beijing and Shanghai will take effective measures to save water and protect water resources.
Beijing will stick more strictly to water-saving policies through the readjustment(调整) of industrial structures. Beijing is expected to be short of 1.185 billion cubic metres of water by 2020. Beijing will shut down factories with high water consumption(消耗) and pollution including electric power, steel and paper making equipments. Advanced water-saving technology will be introduced to new industrial projects in the capital city.
Grain-growing areas will be reduced to save ground water and more trees will be planted. Animal breeding and other “highly efficient” agriculture with modern water-saving irrigation methods will be developed.
