Topic: Risk Assessment and Analysis

Wildfire regimes are changing globally with an increase in global burned area and changes in fire characteristics. Recent research shows that the number of extreme fire events is increasing exponentially and events such as the most recent fires in Los Angeles in the U.S. (2025), the Hawaii fires…

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. Community Wildfire Protection…

Background

In the face of increased complexity, the USDA Forest Service (Forest Service) is emphasizing the use of risk-based spatial analytics and expert coaching of fire managers through consistent processes and practices to inform safer, effective, and strategic…

Pathways to achieving net-zero and net-negative greenhouse-gas (GHG) emission targets rely on land-based contributions to carbon (C) sequestration. However, projections of future contributions neglect to consider ecosystems, climate change, legacy impacts of continental-scale fire exclusion,…

Wildfire’s destruction of homes is an increasingly serious global problem. Research indicates that characterizing home hardening and defensible space at the individual structure level may reduce loss through enriched understanding of structure susceptibility in the built environment. However,…

Flood events in post-fire environments produce cascading social and ecological consequences that are challenging to anticipate, mitigate, and manage. Engaging private property owners in mitigation is complex, and the drivers that motivate action or inaction are not yet well defined. We analyse…

As the realized experiences of wildfires threatening communities increase, the importance of proactive evacuation preparation and wildfire risk mitigation on private property to reduce the loss of lives and property is shaping wildfire policy and programs. To date, research has focused on pre-…

Development in the wildland-urban interface is increasing exposure to wildfire risks in the western United States. Yet, among the components of risk—hazard, vulnerability, and exposure—mitigating exposure has arguably been most difficult. In this report, we describe the set of interconnected…

Wildland firefighters play a critical role in managing the complex relationship between humans and fire. To reduce the inherent risks that come with this role, firefighters use safety protocols such as lookouts, communications, escape routes, and safety zones (LCES). Currently, LCES…

Introduction: Growing concerns about fire across the western United States, and commensurate emphasis on treating expansive areas over the next 2 decades, have created a need to develop tools for managers to assess management benefits and impacts across spatial scales. We…
