Building urban resilience with nature
The reintroduction of nature into our rapidly growing cities is necessary to strengthen urban resilience and promote long-term human wellbeing. Even in our most densely populated urban centers, nature provides clean drinking water, serves as a much-needed buffer against the devastation from severe storms, and provides respite from rising temperatures and stifling heat waves. Beyond delivering these critical services, nature provides our communities and economy with valuable co-benefits that build community resilience and support individual well-being. From improved health outcomes to lowered crime rates, the integration of natural spaces in the urban environment helps solve important problems and improves the daily lives of a diverse and growing urban population.i ii Though nature has always supported our cities, the full value of nature’s benefits has rarely been calculated or included in decision making or scenario analysis. Most often, planners have chosen to meet their needs with larger and more complex “grey” infrastructure such as large, reticulated water distribution systems and highly engineered, armored coastlines. Nature has long been taken for granted or entirely ignored as an asset or resource to meet challenges brought by urbanization, globalization, and climate change. As a result, massive and often expensive grey infrastructure projects have been built as the preferred solutions to most of our urban needs, even when equally or more effective natural infrastructure solutions exist. Today, as the global challenges of sea level rise, warming, and urban development intensify, city leaders are seeking cost-effective projects that offer predictable performance and long-term resilience. Nature and nature-based infrastructure are becoming recognized as an alternative for many cities. They not only meet specific service targets for water supply or flood management, but also provide a broad array of co-benefits, such as creating new parks and advancing equity and health for underserved neighborhoods. Interest in and support for natural infrastructure are increasing, but uptake is slow. Many cities simply lack the required data, technical expertise, business cases, or procedural know-how to implement these alternatives to traditionally engineered responses.
