From Planetary Evolution to Emerging Hazards: A Conceptual Framework for Earth System Dynamics and Disaster Risk (A Forward-Looking and Dynamic Framework)

This Working Paper presents the Earth System–Disaster Risk Evolution Framework (ES-DREF), a forward-looking conceptual framework developed to examine how transformations within the Earth system and human systems interact to reshape hazard patterns and influence the evolution of disaster risk in the twenty-first century. The study addresses the growing limitations of conventional disaster risk approaches that primarily treat hazards as isolated natural events. It conceptualizes disaster risk as an evolving, systemic phenomenon emerging from interactions among Earth system processes, anthropogenic pressures, changing hazard dynamics, vulnerability, and governance capacities. The Working Paper adopts a conceptual research design based on an integrative literature review and applies systems thinking as its primary analytical lens. The framework integrates insights from Earth System Science, Disaster Risk Reduction, climate science, resilience science, and risk governance. ES-DREF is structured as a multi-layer conceptual model encompassing: (1) Earth System Transformation, (2) Human System Transformation, (3) Emerging Hazard Dynamics, (4) Disaster Risk Evolution, and (5) Adaptive and Resilience-Oriented Governance. Particular attention is given to cross-scale interactions, feedback loops, non-linearity, thresholds, systemic risk, and adaptive learning. The framework seeks to provide a coherent conceptual basis for understanding how environmental and societal transformations can generate new hazard configurations and alter the spatial, temporal, and systemic characteristics of disaster risk. Rather than presenting a predictive model, ES-DREF is proposed as an analytical and policy-oriented framework that can support future research, risk assessment, disaster risk reduction, resilience planning, and adaptive governance. The Working Paper contributes to ongoing discussions on systemic risk and the transformation of disaster risk in an increasingly interconnected and rapidly changing Earth system.
