Cities did not somehow emerge fully formed; they developed gradually – usually in oscillating, uneven lurches of development over time. Exacerbated by climate change, extreme weather events and sea levels are rising rapidly. This poses a significant, immediate threat to coastal or riverine cities and the priceless historic resources that make them unique. As protecting cultural heritage becomes a global priority, identifying effective strategies that governments can use to identify, manage, and protect historic resources is critical. This chapter is divided into two sections. The first part discusses some of the public health benefits that historic resources bring to urban areas and how cultural heritage increases urban resilience. The second section analyzes two important technological strategies that governments at all levels should have (or develop) to fulfill their legal obligations to protect cultural heritage by engaging the public more broadly in preservation initiatives.
