Let’s face it. Buzz words such as smart cities and technologies, green urbanism, blue-green infrastructure, sustainable urban development, transformation of city structures, carless society, smart farming in urban areas, and the like, have been spreading like virus among experts, academics, as well as practitioners, who are involved in activities to save our planet.

This international gathering of experts and academics was held at the Beijing Tsinghua Tongheng Urban Planning and Design Institute, in cooperation with the Technical University Berlin and the Deutsche Akademische Austauschdienst (DAAD) of Germany.
