"Clean water" is included as the United Nations Sustainable Development Goals (SDGs) 6 while there are 4 billion people around the world still suffer from severe water scarcity for at least one month a year. At the meantime, global economic integration has greatly promoted the geographical separation of production and consumption caused by trade, leading to the trans-regional flow of a large amount of water resources in the global commodity supply chain.
In this study, the concept of “telecoupled water withdrawal” was proposed and a multi-regional input-output model was constructed based on domestic and international nested data. A high spatial and sectoral resolution water use list of 350 cities in China was established under domestic and international remote consumption, and the key countries and regions affecting the pattern of urban water use in China were identified. The research results provide data support for understanding the remote coupling between local water use and remote consumption, and provide scientific reference for the collaborative sustainability of urban water resources management and inter-regional trade in China.
