Social-Ecological Consequences of Future Wildfires and Smoke in the West

Over the past two decades, wildfires in western North America have greatly increased in frequency, magnitude and severity. Scientists have documented three main causes - a century of suppression and inadequate forest management that has led to overly dense, fuel-rich forests; climate change, turning woodlands and grasslands into hot, dry tinder boxes; and the spread of urbanization, increasing the probability of man-made ignitions. Less well known are the environmental and social implications associated with the acceleration of these trends. To explore these concerns and to identify possible policy responses, the National Academies of Sciences, Engineering, and Medicine's Board on Environmental Change and Society, in partnership with the Royal Society of Canada, convened a workshop in June 2024, "The Social and Ecological Consequences of Future Wildfire in the West". Over two days, two dozen wildfire experts and a hybrid audience of over 200 participants explored the history, current state, and anticipated future of wildfire science and policy across the western United States and Canada. This publication summarizes the presentations and discussions of the workshop.
