The document discusses nature-based solutions for urban water management. It proposes using ecosystem properties and green infrastructure to regulate hydrology and biota through dual regulation. This involves harmonizing ecohydrological measures with necessary infrastructure and integrating various regulations to stabilize and improve water quality. Nature-based solutions could help with urban regeneration, coastal resilience, and more sustainable resource use while enhancing ecosystem services. However, their actual benefits depend on proper planning and management across spatial scales from cities to suburban areas. Societal choices also influence the adoption of such solutions.
