We are grateful to the numerous representatatives from municipalities and intergovernmental, nongovernmental, and community-based organizations who participated in the case study research.

The survey research, and research at most case sites, was supported by a grant from the Infrastructure Management and Extreme Events Program of the United States National Science Foundation. Additional research comparing cities in Japan and the United States was supported by the Social Science Research Council.

The Rockefeller Foundation facilitated the convening of urban adaptation leaders from around the world by awarding use of their Bellagio Study and Conference Center.
