This study is creating a joint vision by German and Chinese experts: How can Changde be developed if water (river water, rain water, waste water) in the city is not considered to be a problem but a starting point for an integrated urban development strategy? In the concept “Changde Water City 2020” two design tasks of the (near) future are combined:
· the water management challenge (create more space and better quality for water)
· The urban development challenge (vital economy and high quality living environments).
The city of Changde follows the strategy to develop its character as the “city of three mountains and three rivers”, a “garden and ecological city” as well as “one city, four districts, two riverbanks” and “modern fairyland city”. In all these concepts the appearance and atmosphere of Changde as a water city play a major role and water is seen as an important identity builder. But what is seen now is that water is hardly visible and of insufficient quality within the city – while the agricultural landscapes surrounding the city are dominated by streams, canals and lakes. The aim is to return the water to the experience of people’s lives also within the city.
This study is examining and giving guidelines how to create an urban water landscape by setting up an ecological watershed management within the city of Changde. This suggests that there should be clear connection between the underlying structures of topography, hydrology and soils and the major structuring elements of urban form, such as the use of catchments as the basis for physical planning and regulation. There is an obvious synergy between the need to create networks of open space to serve social and ecological needs and new approaches to open systems of urban water management.
Currently many cities around the world are setting up “water sensitive urban design guidelines”, “integrated urban drainage strategies” or “urban water plans” in order to restructure their open space systems to regulate floods, collect and treat urban runoff and at the same time improving recreation opportunities and enhance biodiversity. Drawing up on these experiences a tailor-made strategy for the urban landscape of Changde will be developed, that can at the same time serve as a model-strategy for other Chinese and Asian cities. This masterplan reintegrates different water-related urban issues for a comprehensive towards more sustainable urban design and improvement of environmental conditions. The interconnected systems of water, people and development on the land must first be seen and understood as an integrated whole before citizens, developers and their leaders can act intelligently to protect them. This masterplan is intended to assist in building this understanding.
The results of the study will be presented in the form of a brochure including both: texts (English and Chinese) and graphics as well as maps (see attached layout template). The aim is to create an informative, understandable document for a broad range of actors related to urban development and watershed management:
· Different government agencies and officials
· Land developers
· Planners and consultants
Unlike traditional design brochures or engineering reports, whose concepts of site development, environmental quality, landscape and drainage guidelines are presented separately and often in a language that is exclusive to address their special audience, this masterplan works to keep the different aspects of urban water management together.
