Abstract
Northwest China has abundant light, heat, and land resources, but limited water resources which has restricted the sustainable development of food security in this region. Water-use efficiency in crop production, water resources stress, and virtual water output of crops in Northwest China are evaluated using water footprint and virtual water as analysis tools. Grain production and agricultural water use in Northwest China are predicted. Furthermore, policy suggestions are proposed to guarantee the sustainable development of water resources and food security in Northwest China, including gradually reducing the scale of agricultural water use in this region, optimizing the crop planting structure, and implementing a virtual water project along the Silk Road Economic Belt. This study is hoped to provide a reference for the rational utilization of regional water resources and the formulation of food security strategies.
