Agricultural green and blue water uses in China are accounted for based on the H08 hydrological model. The results indicate that green and blue water uses play various roles in different regions of China. Two different time series trends and their associated drivers are highlighted for the period 1981–2010. Phase advance is found in the annual cycle of blue water use in comparison with green water use. An impact assessment shows that blue water use has a considerable impact on the water system, accounting for more than three quarters of renewable water resources in China. In addition, a large amount of non-renewable water is used in northern China.
