Summary
Delta cities worldwide are confronted with great challenges concerning flood risks, environmental pressures and other water-related urban issues. The complexity in both physical and social dimensions lies in diverse (and in many cases conflicting) values held by a wide variety of actors in spatial development. These values are shaped by the long-term impacts of natural forces, political powers, development ideologies, economic models, social structures, and local cultures. Defining the central role of “water” in structuring delta cities, this research applies the value concept as a particular lens to study how water is valued in each society through history. It argues that the recognition of diverse water values can help bridge the interplay between physical and societal systems within the delta, which can play a central role in developing urban planning and design strategies towards sustainable and liveable urban water environments.
