Social and Community Impacts of Fire

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.

Background

Wildfire poses an increasing threat to communities in the Western US, driven by climate change and rising human settlement in the wildland-urban interface (WUI). It is imperative that communities in fire-prone areas become “fire-adapted” to safely manage their risk.

Wildland firefighters (WLFFs) face significant brain health risks due to prolonged exposure to smoke, extreme heat, dehydration, physical exertion and irregular sleep patterns. Here, the literature is presented as a narrative review on studies that inform our knowledge on WLFF brain health.

The James M. Inhofe National Defence Authorization Act for Fiscal Year 2023 established that certain illnesses and diseases are to be deemed as proximately caused by employment in federal fire protection activities. However, cancers affecting female wildland firefighters were not included on this list and are recommended for further evaluation.

Background

Wildland firefighting requires exposure to long shifts and poor sleep, which may pose a risk to worker safety due to impaired cognitive function.

Aims

We investigated the associations between sleep, shift characteristics, and cognitive function in wildland firefighters.

Methods

Climate change and decades of fire suppression are increasing the risk of wildfire in many rural and remote communities across Canada. Yet limited research has been done to better understand how these communities experience wildfire risk.
