Keywords: multi-objective decision; water-energy-food nexus; irrigation; power system; fishery
执行年限/Time: 2020.01 - 2023.12
Hydropower is an important part of power systems in many regions globally. The operations of hydropower have significant impacts on other water utilization and the ecosystem of rivers, such as the fishery relying on the flows in water courses, aquatic entertainments, water diversion for irrigation, etc. Due to the increase of water demands and external impacts of climate change, the competition and synergy among water, energy and food will play a more and more important role in the water allocation in short and medium term and system sustainability in long term. This study will choose the large Lancang-Mekong River shared by China and Southeast Asia and small-to-medial rivers in Chile, and conduct joint investigations in water-energy-food nexus on different scales. The study aims to enhance the understanding towards the balance among multiple competitive water utilizations including hydropower, irrigation, fishery, entertainment, etc. A river basin wide water-energy-food model and a coupled model with power system model will be built and policy suggestions on balancing the interests of different sectors and regions will be initiated.
