Seawalls or social recovery? The role of policy networks and design in disaster recovery

Abstract

This mixed-methods study examines the case of 30 advisory committees across 25 municipalities in Miyagi and Iwate Prefectures in northeast Japan after the 3/11 triple disasters. Drawing on synthetic control experiments, social network analysis, and case studies, we test whether the design of these committees’ policies or the traits of these committee networks improved the recovery trajectories of municipalities. We find that communities highly connected to this network of advisory committees saw better economic recovery than expected, especially when researchers, hyper-connected individuals, or plans for community centers were involved, controlling for disaster damage, infrastructure quality, social vulnerability, governance capacity, emergency services, and social capital. Our results bring with them a number of concrete policy recommendations for disaster managers, local residents, and decision makers.
