Wildfire Risk Assessment

Wildfire Risk Assessment is the geospatial process of evaluating the likelihood and potential consequences of wildfire across landscapes by analyzing fuel conditions, terrain, weather patterns, ignition sources, and the exposure of communities and infrastructure. As wildfire seasons intensify globally due to climate change, drought, and expanding urban-wildland interfaces, comprehensive spatial risk assessment has become essential for fire management agencies, land use planners, insurers, and communities seeking to reduce losses and improve resilience.

Historical fire perimeter data and ignition records reveal spatial patterns of fire occurrence and recurrence. Weather and climate data provide information on temperature, humidity, wind, and drought conditions that drive fire behavior. Wildland-urban interface mapping delineates areas where development intermingles with fire-prone vegetation, identifying the communities most exposed to wildfire. Infrastructure mapping locates roads, power lines, water supplies, and evacuation routes critical for fire response. Applications and ChallengesFuel management planning uses risk maps to prioritize prescribed burning, mechanical thinning, and defensible space programs in the highest-risk areas. Community wildfire protection plans use spatial risk assessment to guide home hardening, access improvement, and evacuation planningEvacuation PlanningEvacuation Planning develops routes, timing, and logistics for safely moving populations away from hazard zones durin....

Key challenges include the dynamic nature of fire risk that changes with weather, season, and vegetation growth, the difficulty of predicting individual fire behavior in complex terrain, managing the expanding wildland-urban interface, and allocating limited fire management resources across vast fire-prone landscapes.
