Overall, China has over 27 percent of its area irrigated from groundwater and about 50 percent in the North China Plains. The percentage can reach as much as 80 percent in developed countries with a mild climate (Germany) and in arid countries (Saudi Arabia, Libya). In many countries, groundwater use has reached its threshold.
