The adaptive shift: Embracing complexity in disaster and emergency management

Disaster and Emergency Management (DEM) systems are increasingly challenged by the complexity and interconnectedness of today's DEM environment. While rigid, phased-based approaches to DEM provide valuable structural frameworks, they often fail in addressing the dynamic, non-linear, and unpredictable nature of contemporary disasters. This paper critically examines key challenges in DEM, including non-linearity, complexity, and the coordination of diverse actors and organisations. It advocates for a shift towards adaptive, interconnected systems that better align with the realities of complex disasters. To this end, the paper introduces the Complex Adaptive DEM (CADEM) Framework, a new conceptual framework grounded in Complex Adaptive Systems (CAS) theory. This framework emphasises decentralised decision-making, interorganisational collaboration, and emergent behaviours as mechanisms to enhance the adaptability and resilience of DEM systems. By reframing DEM as a networked and adaptive system, CADEM provides a pathway for navigating the multifaceted challenges of contemporary disasters. • The phased approach fails to address the non-linear nature of disasters. • Complex adaptive system principles address complexity in disasters. • Decentralised decision-making for disaster management. • Inter-organisational collaboration improves disaster management.
