Climate change affects urban areas through water. It intensifies water scarcity and flooding, increases salinization of groundwater, and heightens the need for green spaces for flood mitigation, shade and cooling. Each of these issues are interrelated and impact each other to varying degrees. For example, urban flooding can be mitigated by increasing green areas. These areas can then provide shade which can lead to a decrease in ground temperature.
The natural water systems often connect to urban water resources at a river basin level; where water flows are affected by land use, building distribution, and infrastructure. Urban population growth is increasing pressure on scarce resources. This means an increasing need for integrated approaches connecting the different water systems in urban areas. The urban water systems and department are often not working together, there is a need to better interlink the work of climate change, the natural water systems, water supply, stormwater drainage and sewer systems for urban climate resilience and water security.
Humanity must take up the challenge to pool its resources and innovations toward sustainable and resilient urban areas. Otherwise, disasters, climate change, rapid urbanization, and other unsustainable development pose a serious risk to the prosperous future of urban areas, and their livability. Many climates and water-cautious solutions and adaptations are available. This community aims to share knowledge of good practices for urban climate resilience, from assessment to strategies and finance, to governance and implementation, and innovation.
