From event analysis to global lessons: disaster forensics for building resilience

Abstract. With unprecedented growth in disaster risk, there is an urgent need for enhanced learning and understanding of disasters, particularly in relation to the trends in drivers of increasing risk. Building on the disaster forensics field, we introduce the post-event review capability (PERC) methodology for systematically and holistically analysing disaster events, and identifying actionable recommendations. PERC responds to a need for learning about the successes and failures in disaster risk management and resilience, and uncovers the underlying drivers of increasing risk. We draw generalisable insights identified from seven applications of the methodology to date, where we find that across the globe policy makers and practitioners in disaster risk management face strikingly similar challenges despite variations in context, indicating encouraging potential for mutual learning. These lessons highlight the importance of integrated risk reduction strategies. We invite others to utilise the freely available PERC approach and contribute to building a repository of learning on disaster risk management and resilience.
