Natural disaster economics is a specialized field of study within applied economics that systematically analyzes the economic dimensions of natural hazards and disasters across their full lifecycle. It investigates the economic causes, consequences, and policy responses related to natural hazard events, including the assessment of direct and indirect economic impacts, the economic evaluation of preparedness and mitigation strategies, the analysis of financing mechanisms for disaster response and recovery, and the study of long-term resilience and adaptation. Employing quantitative methods and economic theory, this research area provides critical insights for informing effective disaster risk reduction policies, optimizing resource allocation, and enhancing societal economic resilience against natural hazard threats.
