The concluding chapter provides a synthesis and reflection on insights from this book. It first summarizes the main findings regarding how disaster risk today is a legacy of urban history, drawing on salient examples from the six case study cities and cautioning that risk becomes very “path dependent” as future options are constrained by past decisions. After discussing limitations of the study and further research needs, the chapter suggests that the Urban Risk Dynamics framework and findings from the six cases are relevant to any city, demonstrating this for Vancouver (Canada). It then reflects on the practical significance of the book. It argues that the findings demonstrate why disaster risk and risk reduction should be viewed dynamically; why understanding risk should start with the city, not the hazard or disaster; and why interdisciplinary approaches are critical for reducing risk. Recognizing this can help analysts, planners, and policy-makers, for example, to not only identify current risk hotspots but anticipate future ones, to consider risk from a multihazard standpoint, and to develop strategies and solutions that are effective in the long term.
