Disaster risk management tipping points: impacts of extreme wildfire events and the resulting need for layered disaster risk management solutions
Year: 2025
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 (2023), Canada’s record-breaking fires (2023), the largest recorded fires in Greece-Europe (2023) and the 2025 European fire season underpin this observation.Extreme wildfire events (EWEs) thereby pose new challenges and limits to managing disaster risk. This refers not only to response operations but…

Global Synthesis of Quantification of Fire Behaviour Characteristics in Forests and Shrublands: Recent Progress
Year: 2025
Purpose of ReviewThe behaviour of wildland fires, namely their free spreading nature, destructive energy fluxes and hazardous environment, make it a phenomenon difficult to study. Field experimental studies and occasional wildfire observations underpin our understanding of fire behaviour. We aim to present a global synthesis of field-based studies in forest and shrublands fuel types published since 2003 with a focus on the most commonly measured fire behaviour attributes, namely rate of fire spread, ignition and spread sustainability, flame characteristics, fuel consumption…

Spatiotemporal dynamics of fine dead surface fuel moisture content in a Colorado mixed-conifer forest
Year: 2025
BackgroundDead fine fuel moisture content (FMC) is critical for predicting fire behavior and effects. Spatiotemporal variation in FMC occurs due to to variability in atmospheric conditions at the fuel interface, which is influenced by interacting factors including local forest structure and topography. Previous research has primarily examined these patterns over coarse spatial scales and relied on few factors to explain variability.AimsIn this study, we monitored the spatiotemporal variability in FMC and characterized how controls of FMC vary over a fire…
