Abstract: On the basis of variation characteristics analysis of China's agricultural water, this paper
explored the relationship between agricultural water and food security, and proposed the prospects for the
trend of agricultural water. The results are as follows: (1) The basic stability of total agricultural water, the
steady improvement in water efficiency, and the coexistence of shortages and inefficiencies are the three main
characteristics of China's agricultural water. (2) As long as keeping the current development trend of China's
irrigation area and grain yield, grain security can be fundamentally guaranteed in 2020, and agricultural water
can meet the food security needs. (3) The prospects of China's agricultural water are that the efficiency of
agricul
