Perspective article: Mitigating social and economic impact of wildfires

Abstract

Wildfires are a natural part of the earth's ecosystem. Over time, the social and economic consequences have significantly increased as development in or near forested areas (i.e. the wildland/urban interface or WUI) has continued, resulting in more value and lives exposed to wildfire events, and due to increasingly large wildfire prone regions and extended seasons caused by changes in the climate. The most significant events are, by some measures, hardly ‘wildland fires’, they are more massive conflagrations affecting communities of burning homes and businesses. The total area around the world that can reasonably be regarded in ‘high fire risk’ is beyond the level of controlled burns, forest thinning, or one-by-one implementation of defensible spaces around structures and homes. Current policies are not effective at the scale of the problem. Better capabilities are needed to provide key decisionmakers including land use planners, building code officials, and wildland managers the right tools to manage this risk. A well designed and governed public private partnership is required. The combustion research community will be at the core of the development that can make it successful, but they will need to band together to bring their numerous individual skills to the table together.
