With a changing climate, sea levels are expected to rise at an increasing rate over the next centuries, jeopardizing populations living in smaller or larger urban communities along the coastlines. The extent and speed of this process is uncertain, which puts coastal cities in the difficult position of deciding which urban planning and design responses are adequate. Also, the complexity and extended time-frame of this wicked problem calls for multidisciplinary and open-minded approaches, where knowledge, practice, and visions for the future all contribute to robust, evidence-based, and locally attuned adaption. This book tackles the challenge of sea level rise and how cities can respond.
