Post-disaster recovery systems: A systematic review of the Wenchuan earthquake

Abstract. Wenchuan earthquake is one of the most extensively studied large-scale disaster-recovery scenarios, providing a unique empirical basis for understanding the design, implementation, and sustainability of complex recovery systems. However, governance, infrastructural, social, economic, and environmental research is fragmented, limiting system-level knowledge of post-disaster recovery processes. Addressing this gap, a systematic analysis of 735 peer-reviewed articles from 2008 to 2025 aims to synthesize interdisciplinary evidence on post-disaster recovery. The PRISMA-guided assessment incorporates interdisciplinary insights into governance, infrastructure reconstruction, social recovery, livelihood regeneration, environmental restoration, and technology innovation. Institutional capabilities, resource mobilization, and risk circumstances alter recovery as a dynamic system-level transformation. Governance coordinates sectoral policymaking. Centrally coordinated systems, particularly the paired-assistance model and large-scale financing, enabled rapid and complete reconstruction in Wenchuan. The research also indicates coordination inefficiencies, uneven recovery outcomes, and policy goals that don't fit local realities. The review reveals that social and environmental variables affect long-term rehabilitation beyond physical recovery. Psychosocial rehabilitation, community cohesion, and livelihood stability take longer than infrastructure restoration and are seldom planned. Landslides and debris flows influenced recovery over time in dynamic hazard settings. To remedy such shortcomings, a governance-mediated post-disaster recovery paradigm, defined by enabling conditions and structural constraints, is proposed. The approach links policy tools to cross-domain recovery processes and emphasizes adaptive learning and long-term resilience to increase understanding. Future catastrophe recovery methods must combine rapid rebuilding with high-quality coordination, social inclusion, environmental risk management, and system resilience, as shown by the Wenchuan experience.
