Can a relational cross-scalar approach to management improve environmental disaster responses? A case study of an unprecedented flood in New South Wales, Australia

Human societies face planetary crises of climate change, biodiversity loss and pollution. Conventional command-and-control approaches to manage these existential challenges have failed due to limited comprehension of relationships in social-ecological systems. To address this problem, we study the complex case of the disaster response to unprecedented floods in the Northern Rivers Region, New South Wales, Australia, in 2022. We apply a novel relational-systems model that identifies management structures, processes, functions and contents interacting at and across scales. The model helps identify the root causes in the inadequate disaster response that ensued in the Northern Rivers Region flooding. The root causes are a lack of systems-thinking competence, poor collaborative capacity, vulnerabilities in environmental management and deficient governance systems. The relational complexity concepts of self-organisation and socio-cultural organisation may further help explain variation in response to disasters in different socio-ecological contexts. Such understanding can inform individual and collective environmental action.
