Exploring options to grow rice using less water in northern China using a modelling approach

Because of increasing competition for water, water-saving technologies such as alternate wetting and drying and aerobic rice are being developed to reduce water use while maintaining a high yield of rice. The components of the water balance of these systems need to be disentangled to extrapolate water savings at the field scale to the irrigation system scale. In this study, simulation modelling was used to quantify yield, water productivity, and...
