Fire Intensity and spRead forecAst (FIRA): A Machine Learning Based Fire Spread Prediction Model for Air Quality Forecasting Application
Year: 2025
Fire activities introduce hazardous impacts on the environment and public health by emitting various chemical species into the atmosphere. Most operational air quality forecast (AQF) models estimate smoke emissions based on the latest available satellite fire products, which may not represent real-time fire behaviors without considering fire spread. Hence, a novel machine learning (ML) based fire spread forecast model, the Fire Intensity and spRead forecAst (FIRA), is developed for AQF model applications. FIRA aims to improve the performance of AQF models by providing realistic, dynamic fire…

Climate Change Contributions to US Wildfire Smoke PM2.5 Mortality Between 2006-2020
Year: 2025
RATIONALE Wildfires have increased in frequency and intensity due to climate change and now contribute to nearly half of the annual average of fine particulate matter in the US. While the effects of short-term wildfire-PM2.5 exposure on respiratory diseases are well-described, the impact of climate change on longer duration wildfire-PM2.5 mortality is unknown. Our aim was to determine the contribution of anthropogenic climate change to wildfire smoke PM2.5 mortality on a county-level across the conterminous US between 2006-2020. METHODS We use an attribution model to compare observed wildfire…

Understanding rural adaptation to smoke from wildfires and forest management: insights for aligning approaches with community contexts
Year: 2025
Background: Rural communities are increasingly impacted by smoke produced by wildfires and forest management activties. Understanding local influences on smoke adaptation and mitigation is critical to social adaptation as fire risk continues to rise.Aims: We sought to determine the role of local social context in smoke adaptation and gauge interest in adaptation strategies that might reduce exposure.Methods: We conducted 46 semi-structured interviews with 56 residents and professionals in Parks, Arizona, USA, a rural community adjacent to…

Burning from the ground up: the structure and impact of Prescribed Burn Associations in the United States
Year: 2025
Background: To combat losses and threats from fire exclusion and extreme wildfire events, communities in the United States are increasingly self-organizing through locally led Prescribed Burn Associations (PBAs) to plan and implement prescribed burns on private lands.Aim: Our study aimed to document the expansion of PBAs and provide insight into their structure, function, and impacts.Methods: Leaders from 135 known PBAs across the United States were invited to participate in an online survey.Key results: Survey results demonstrate a widespread emergence of PBAs in the United States,…

Trajectories of community fire adaptation: Social diversity, social fragmentation and the temporal evolution of wildfire action
Year: 2025
There is increasing acknowledgement that the unique characteristics (i.e., social contexts) of human communities influence variable means for adapting to the growing risks posed by wildland fire. However, there has been less work documenting how community social contexts evolve over time, and the ways they might influence collective mitigations pursued in partnership with professionals when addressing wildfire planning. We conducted 73 semi-structured interviews with 112 residents, emergency management professionals, government officials and members of community organizations in two Nevada…

Integrating fire-smart fuels management with bioenergy benefits remote and Indigenous communities in Canada
Year: 2025
The global urgency of more damaging wildfires calls for proactive solutions. Integrating fire-smart fuels management with bioenergy could reduce wildfire risk while providing feedstock for bioenergy. We explore this strategy in off-grid communities in Canada who are heavily dependent on diesel for their energy needs, many of which are home to Indigenous peoples. Combining national remote sensing data and community-based information, we identify 33 diesel-dependent communities at high wildfire risk due to a large accumulation of undisturbed flammable forest. We demonstrate that 30 of these 33…

Location, Location, Location: The Influence of Local Social Complexity on Risk Reduction Strategies in a WUI Settlement
Year: 2025
This research builds from existing scholarship to highlight the important role social complexity plays on managing and mitigating wildfire risk in the wildland-urban interface. Researchers employed in-depth interviews to uncover similarities and differences in land and wildfire management preferences among what would appear to many to be a relatively homogenous population in a valley on the outskirts of Salt Lake City, Utah. In spite of demographic similarities, researchers found meaningful and complex differences with regard to the local social context of subpopulations within the drainage.…

Equity in resilience: a case study of community resilience to wildfire in southwestern Oregon, United States
Year: 2025
In the fire-prone and fire-adapted landscape of the Rogue River Basin of southwestern Oregon, communities mobilize to prepare, respond, and recover from wildfire while modifying the current social and ecological system. Marginalized communities are often most affected and least prepared for disturbances of this kind, where racism, colonialism, and structural equities prevent meaningful inclusion and equitable allocation of resources. This research centers these voices in an empirical study of the situated resilience of the Rogue River Basin, rooted in the work of community-based organizations…
