Nature-based Solutions

Browse resources on green infrastructure and other nature-based solutions – cost-effective approaches to prepare cities for climate change impacts.

Improving urban resilience is critical for cities to cope with climate-related extreme weather events and natural disasters. Nature-based solutions and green infrastructure provide cost-effective and resource-efficient approaches that increase a city's capacity to respond to disasters and shocks. Nature-based solutions, such as planting trees to improve urban air quality, revitalizing unused or contaminated land into parks, greening roofs to reduce buildings energy use, and restoring degraded wetlands to mitigate flooding, are increasingly implemented in urban areas to enhance urban resilience.
