This paper analyzed the state of water shortage in North China using Hebei Province as a case study. The study expatiates on modern water-saving agriculture and shows that agriculture is a key to water-saving. In North China, water-saving agriculture is determined by reducing water use for wheat production. In addition to engineering wa- ter-saving, greater attention should be paid to biological water-saving and agr
