Wildfire Exposure, Impact, and Recovery: Climate inequality lessons from Australia’s Black Summer
This presentation synthesizes a series of studies examining the connection between wildfires and socioeconomic vulnerability in Australia, with a particular focus on the Black Summer fires of 2019–2020. These catastrophic wildfires highlighted significant social and economic inequalities related to wildfire exposure, impacts, and recovery, providing critical insights for climate justice and disaster resilience frameworks. Regression analyses of administrative burn data and census data reveal that disadvantaged communities experienced disproportionately high wildfire hazard exposure, with notable spatial differences across urban, peri-urban, and remote regions. Longitudinal analyses from 2010 to 2022, which integrated Historical Bushfire Boundaries and census data, show persistent correlations between socioeconomic disadvantage and increased wildfire frequency, duration, and severity, reinforcing a cycle of vulnerability. Post-disaster recovery trajectories, measured through satellite-derived nightlight radiance and geolocated movement data, demonstrate significant disparities: rural and low-income urban areas faced extended economic stagnation, worsening existing inequalities. An intersectional analysis of well-being losses—including weekly income, housing security, and gendered unpaid labour burdens—reveals that low-income populations, women, and peri-urban communities experienced concentrated impacts. These findings challenge traditional disaster management approaches, emphasizing the need for equity-centered policy frameworks that address the spatial, temporal, socioeconomic and demographic variations in risk exposure and recovery.
Speaker profile
Dr Sonia Akter is an Associate Professor at the Australian National University’s Crawford School of Public Policy, specializing in agriculture-environment-development dynamics in the Asia-Pacific. With a PhD in Environmental Management (ANU, 2010) and a Master’s in Economics (York University, Canada), she previously served as Assistant Professor at the National University of Singapore (2015–2022) and held research roles at the International Rice Research Institute (IRRI) and Germany’s Helmholtz Centre. Her work examines climate vulnerabilities to natural disasters—including floods, wildfires, and cyclones—and their disproportionate impacts on low-income and marginalized communities in Australia and South/Southeast Asia. Published in Nature Water and Global Environmental Change, her findings draw on fieldwork in Australia, Bangladesh, Cambodia, Indonesia, and Timor-Leste. She advocates for equitable disaster resilience and food systems, advising UNDRR and regional policy initiatives on sustainable development.
Weekly seminar series
As part of our Centre's vibrant research culture, we host a weekly seminar series. Visiting and invited researchers present current research relating to the economics of health and wellbeing, and the healthcare sector. Visitors are welcome to join these sessions where discussion and debate is encouraged.
