The mission of the Urban and Regional Policy and Its Effects series is to inform policymakers, practitioners, and scholars about the effectiveness of select policy approaches, reforms, and experiments in addressing the key social and economic problems facing today’s cities, suburbs, and metropolitan areas. Volume four of the series introduces and examines thoroughly the concept of regional resilience, explaining how resilience can be promoted - or impeded - by regional characteristics and public policies. The authors illuminate how the walls that now segment metropolitan regions across political jurisdictions and across institutions - and the gaps that separate federal laws from regional realities - have to be bridged in order for regions to cultivate resilience.
