Social and Community Impacts of Fire

Structure fires in the wildland–urban interface (WUI) are becoming more frequent and destructive, yet their emissions of air pollutants remain poorly quantified and are not included in national inventories. Here we present a conterminous-scale inventory of WUI-related structure fire emissions in the United States from 2000 to 2020.

Background

Many regions of the world have seen an increase in highly destructive wildfires, driven by well-documented increases in burned area and growth of housing in the wildland–urban interface (WUI), which exposes more homes to fire. However, it is unclear whether wildfires are also becoming more destructive due to changes in wildfire behavior or in the development patterns of exposed communities.

Wildfires are increasingly affecting people’s lives in the Pacific Northwest. Latine populations, in particular, often face unique challenges in their recovery process. This study examines individual Latine wildfire recovery experiences to understand the strengths and barriers in the community’s post-fire recovery process in two wildfire-affected areas in Oregon and Washington.

As wildfires in the western United States grow in frequency and severity, forest fuels treatment has been increasingly recognized as essential for enhancing forest resilience and mitigating wildfire risks. However, the economic valuation of the treatment's co-benefits remains underexplored, limiting integration into financial and policy decision making.

Background

Growing wildfire risks are increasing losses and damages to wildland-urban interface households in the American West. In Colorado, the December 2021 Marshall Fire destroyed over 1000 suburban homes and became the most destructive fire in the state's history and the 10th costliest in US history.

Wildfire activity has increased in the USA and is projected to accelerate under future climate change^1,2,3.

Background

Exposure to PM_2·5 from wildfire smoke during pregnancy has been implicated as a risk factor for preterm birth. We investigated this association in the prospective nationwide US Environmental Influences on Child Health Outcomes (ECHO) Cohort, focusing on prenatal wildfire PM_2·5 exposure intensity, duration, and timing.
