Uma, S.R.; 2026 Toward improving functional recovery of regional critical infrastructure networks to meet societal priority needs. Lower Hutt, NZ. GNS Science report 2026/01. 27 p.; doi: 10.21420/NPEG-AD97
Abstract
Infrastructure networks are regionally distributed and provide services that support community functioning and economic activity. During hazard events, damage to these networks affects their functionality and results in the disruption of basic services to the community. Post-disaster, the functionality of networks needs to be restored to help communities recover. Recovery is a strategic process. It is important to restore the functionality of networks systematically in a way that prioritises societal needs. Lessons from recent post-disaster recovery experiences have identified the need for better preparedness, planning and structured frameworks for improving the functional recovery of infrastructure systems so that the priority needs of society are met during such emergencies. This study conducted a review to understand factors contributing to the challenges for infrastructure providers when restoring services in a post-disaster setting. The research identified mechanisms and approaches to address these challenges. The study focused on recent guidelines and studies published by international institutions, as well as research initiatives and industry practises in New Zealand that have used a structured framework when undertaking a functional recovery. Key aspects of a functional recovery framework for critical facilities such as hospitals and infrastructure providers were demonstrated using a case study from the Wellington electricity network. Finally, areas are articulated where inter-disciplinary research could improve the functional recovery of regional infrastructure networks to meet societal needs (auth)
