Nature-based solutions (NbS) are solutions inspired or supported by nature. They include ecosystem conservation and restoration measures, as well as the creation or enhancement of natural processes in man-made ecosystems, such as cities. Recent interest in NbS has emphasized their importance for urban water management and cities across the world have begun to experiment with them. Experiences from different contexts, however, are not adequately captured and understood. This book aims to address this gap by compiling case studies and reviews that explore NbS for urban water management from different regions and perspectives and highlight emerging challenges and opportunities for harnessing their potential.
