The purpose of this chapter is to review concepts, approaches, ideas, and tools presented throughout the book and highlight new ideas for incorporating social vulnerability into research and practice, updating the last edition of this book. Much progress has been made toward reducing social vulnerability and building social resilience, but much remains to be done. We invite you to be part of that effort, to remain alert to new materials that become available after the publication of the current edition, and to work collectively to make this world a safer place. This chapter provides a review of the concept of resilience that has permeated throughout this text, along with examples of applications from the United States and the United Kingdom. This chapter also includes a series of checklists designed to be starting points for initial thinking about vulnerability reduction and building resilience in our communities.
