With more frequent extreme weather events and higher average temperatures, there is a clear need to address the impacts of climate change. These impacts are especially high risks for urban areas, as these landscapes already experience higher temperatures and risk of flooding due to the large amounts of impervious surfaces. With the majority of people living in cities and a growing influx of residents, the climate-related problems faced by urban residents represent a challenge to a significant portion of the global population.
However, a potential solution to many of the challenges posed by climate change already exists within many cities. Urban natural areas provide a multitude of environmental benefits, from mitigating stormwater run off to reducing local temperatures. Despite the many benefits of urban natural areas, these spaces are often overlooked when it comes to landscape planning and funding. As a result, a valuable set of tools for mitigating climate change are often under maintained and underfunded. The lack of attention also increases the risk that climate change negatively impacts and damages these natural areas, reducing potential climate solutions and further exacerbating the impacts of climate change.
With this report, we aim to highlight the potential climate mitigating impacts of urban natural areas as well as identify climate-related risks to these natural areas. We acknowledge that the intersection of climate change and urbanization is complex, and one report is unlikely to capture all of the different interactions within urban landscapes. Additionally, many reports explore how urban greenspace is integral to the sustainable design of cities. However, this report will serve as a resource specifically addressing the role of urban nature in the context of climate change. We also present explicit examples both of how urban nature can reduce climate impacts and how city governments and organizations are protecting urban nature from climate change. We recognize cities exist within a complex social governance framework so we focus on the direct impacts and opportunities.
This report summarizes the main threats to one type of urban natural area–forests–and the strategies cities use to minimize or negate these threats. Overall, this report shows that cities use various tactics such as ordinances, zoning, land acquisitions, and federal protections to preserve natural areas. The most successful approaches feature o...
During summer 2022, the Natural Areas Conservancy partnered with 12 cities from the Forests in Cities network to conduct a study focused on quantifying differences in air and surface temperature between types of urban greenspace, with a focus on urban natural areas. As a result of this study, we found that urban natural areas are the coolest class ...
