Urban Water

This book discusses the protection, planning, and design of sustainable urban water environments. Against the backdrop of environmental changes, it addresses issues of water resource protection and sustainable development in China and Germany at different stages of urbanization, as well as relevant strategies and lessons learned.

Despite the strong economic growth of the last decades, our modern global society is facing the existential threat of climate change. It is now realized that the linear economic model is not sustainable in the long run and cannot sustain the life standards. The new circular economy approach that is already under discussion suggests the adjustment of our priorities and the re-orientation of the future infrastructure investments. In this context, we are looking for new, innovative and sustainable solutions to increase the resiliency of our societies, to protect and restore the ecosystems, and to maintain the necessary economic growth without further undermining the planet’s boundaries. The well-being of coming generations will depend on our ability to adapt our economies to this challenge. In particular, transforming today’s cities into sustainable cities is one of the main adaptations that will be necessary. A holistic approach looking at cities from a system’s perspective is neededto achieve this goal.

This book discusses resilient urban water resources management in the context of climate change and ongoing urbanization. Twelve cities worldwide representing different climates and growth stages serve as case studies. Using these case cities, this book first identifies the main water issues, including water demand, floods, and droughts, in relation to the historical development of each city, investigates current strategies for dealing with climate-related water hazards, and explores potential adaptive strategies. The authors draw some common lessons by comparing and contrasting these case studies while acknowledging place-based unique adaptation strategies.
