Less water, more grain in dry Hebei Province, China
Correlation analysis and a water productivity indicator are used to investigate the inverse relationship between increasing grain output and declining irrigation water use in Hebei Province, People's Republic of China, especially since 2003. A rapid improvement in water productivity more than offset the decline in available water even in one of the most water-stressed areas of north China. As long as this trend continues, there is little need for concern about a grain production crisis induced by water shortage.
