Abstract

The study measured the energy-food water footprint and food-food water footprint of 36 prefecture-level cities in the three northeastern provinces from 2000 to 2020 using food and energy-food water footprint evaluation models, and examined the pressurees on available water resources generated by the energy-food water footprint in the three northeastern provinces. The results show that the energy-food water footprints of the three northeastern provinces during the study period are spatially affected by differences in resource endowments, with more than 50 per cent of the regions experiencing high energy-food water pressurees, and the efficiency of water resources utilisation needs to be improved. In this regard, the paper makes recommendations to safeguard the sustainable development of the region and contribute to stabilising the energy-food-water chain balance.
