Why cities need to design for circular water management
Dec 09 2021
Climate change threatens the livability of many places, especially cities. From sea level rise to extreme weather events, to pollution, cities must adapt to a less stable climate with climate adaptation strategies, smart building and landscaping architecture, and infrastructure that mitigates risks while creating livable and eco-socially attractive spaces.
One of the key threats posed by climate change to urban areas is water availability. A destabilized climate will make water supplies more volatile and unpredictable, but the way we think of water only exacerbates this threat. We treat water linearly – source to use to disposal – instead of circularly, and this presents a tremendous opportunity to future-proof cities and make them more livable for centuries to come.
Risk mitigation and resilience in the urban building sector can be achieved through innovative smart and integrated blue-green infrastructure – inclusive water management in particular. We must change the way we use water as part of broader climate adaptation efforts. It’s not just about using less water, discharging more water faster, or building bigger reservoirs. It’s about using water at the right time and in the right place.
