Water-Saving Irrigation Promotion and Food Security: A Study for China

In response to water scarcity and food security, most governments in the world have adopted water-saving irrigation promotion policies by increasing the water-saving irrigation area. Many researches focus on water scarcity, but there is a lack of research on the food security effects of water-saving...
