Infrastructure Impacts and Adaptation Challenges

Creating an overall climate change adaptation strategy for urban infrastructure poses considerable conceptual and operational challenges. An understanding of the characteristics of a city's infrastructure that make it particularly vulnerable to the impacts of climate change is a critical foundation for understanding the severity of the impacts and the means for adaptation. Historical events that have compromised a city's infrastructure under conditions similar to those associated with climate change also provide information about what a city might expect in the way of consequences from a future of increased temperatures, precipitation, and sea level rise. This chapter explores the challenges to climate change adaptation in major urban infrastructure sectors with a focus on New York City, draws lessons from adaptation efforts under way in other large metropolitan regions, and discusses the role of the private sector in urban adaptation.
