The Australian Natural Disaster Resilience Index Volume II - Index Design and Computation

Abstract

Australian communities face increasing losses and disruption from natural disasters. Disaster resilience is a protective characteristic that acts to reduce the effects of, and losses from, natural hazard events. Disaster resilience arises from the capacities of social, economic and government systems to prepare for, respond to and recover from a natural hazard event, and to learn, adapt and transform in anticipation of future natural hazard events. This assessment of disaster resilience estimates the status of these capacities and shows how they are spatially distributed across Australia. <br/> Composite indices are frequently used to summarize and report complex relational measurements about a particular issue. The Australian Natural Disaster Resilience Index measures disaster resilience as a set of coping and adaptive capacities. Coping capacity is the means by which available resources and abilities can be used to face adverse consequences that could lead to a disaster. Adaptive capacity is the arrangements and processes that enable adjustment through learning, adaptation and transformation. Eight themes of disaster resilience encapsulate the resources and abilities that communities have to prepare for, absorb and recover from natural hazards (social character, economic capital, emergency services, planning and the built environment, community capital, information access) or to adapt, learn and solve problems (social and community engagement, governance and leadership). Across the eight themes, 77 indicators were used to compute the Australian Natural Disaster Resilience Index in 2084 areas of Australia, corresponding to the Statistical Area Level 2 divisions of the Australian Bureau of Statistics. <br/> The index was then used to undertake the first nationally standardised assessment of the state of disaster resilience in Australia. Disaster resilience is reported at three levels: an overall disaster resilience index, coping and adaptive capacity sub-indexes and themes of disaster resilience that encapsulate the resources and abilities that communities have to prepare for, absorb and recover from natural hazards and to adapt, learn and solve problems (social character, economic capital, emergency services, planning and the built environment, community capital, information access, social and community engagement, governance and leadership). <br/> Volume II (this volume) describes in detail the computation of the Australian Natural Disaster Resilience Index. This includes resilience concepts, literature review, index structure, data collection, indicators, statistical methods, detailed statistical outputs, sensitivity analysis and uncertainty analyses. <br/> Readers interested in the technical aspects of the Australian Natural Disaster Resilience Index should also consider Volume II. Volume II is comprised of six chapters: <br/> Chapter 1: Design of the Australian Natural Disaster Resilience Index <br/> Chapter 2: Indicators <br/> Chapter 3: Computation of the Australian Natural Disaster Resilience Index <br/> Chapter 4: Statistical outputs: ANDRI, coping capacity and adaptive capacity <br/> Chapter 5: Statistical outputs: disaster resilience themes <br/> Chapter 6: Uncertainty and sensitivity analysis
