Water-Energy-Food system in typical cities of the world and China under zero-waste: Commonalities and asynchronous experiences support sustainable development

Commonalities and asynchronous experiences of realizing zero-waste of water, energy, and food resources between the world and China have critical global importance to support sustainable development, especially for Guangdong-Hong Kong-Macao Greater Bay Area (GBA) urban agglomeration. In this study,...
