SUMMARY:Partner Webinar: Preparing for the “big one”: prescribed fire as a strategic fuel reduction tool
DESCRIPTION:Preparing for the “big one”: prescribed fire as a strategic fuel reduction tool\nApril 2\, 2024 900 – 1030 PST | 1800 – 1930 CET \nHosted by the California Fire Science Consortium \nWildfires are becoming bigger and more severe around the world\, overwhelming firefighters’ capacity to control them. Prescribed fires can be used to safely introduce fire in the landscape and regulate fire regimes through fuel management and by building landscape resilience. Is this approach working? \nThis week\, four fire experts will discuss how fire and resource managers are using prescribed fire to prevent wildfire spread. They will discuss strategic goals and tactics\, tradeoffs between broad landscape resilience and local fuel management\, and whether prescribed fire intensities are enough to affect outcomes. \nPresenters: \n\nTessa Oliver Manager of the Western Cape Umbrella Fire Protection Association\, South Africa\nJorge Andres Saavedra Corporacion Nacional forestal\, CONAF\, Chile\nMarta Miralles\, Catalan Fire Service\, Spain\nStephen Fillmore\, Fuels Operations Specialist USDA Forest Service\, Pacific Southwest Region\, USA\n\nRegister here.

SUMMARY:Partner Webinar: California’s Prescribed Fire (R)evolution: Changing Hearts\, Minds\, and Landscapes
DESCRIPTION:5:00 PM ET\, April 2\, 2024 \nHosted by the California Fires Science Consortium \nDescription: Prescribed fire has undergone major transformation in California over the last decade or two\, evolving from a mostly agency-led practice with limited visibility to a statewide grassroots movement\, engaging and being led by a diversity of partners\, including NGOs\, ranchers\, Indigenous practitioners\, and other community leaders. This movement has been simultaneously organic\, bubbling up at the local level\, and impressively strategic\, pairing local community organizing with state-level liability changes\, new qualifications pathways for practitioners\, and major investments in cutting-edge concepts\, like the state’s $20 million Prescribed Fire Claims Fund. The change during this period has been monumental\, representing an evolution in the way we think about and implement prescribed fire in California\, but it also represents a revolution—the result of a groundswell of passion\, purpose\, and pressure from the most affected communities. This presentation will share insights on California’s prescribed fire evolution/revolution\, and reflect on where it might go from here. \nPresenter: Lenya Quinn-Davidson is the Fire Network Director for the University of California Agriculture and Natural Resources. Lenya’s focus is on the human connection with fire\, and increasing resiliency of California’s landscapes and communities. Lenya works at various scales\, including locally with private landowners and communities members; at the state level\, where she leads UCANR’s Fire Network and collaborates on policy\, research\, and community-based burning; and nationally/internationally\, through her leadership on Women-in-Fire Training Exchanges (WTREX). Lenya is passionate about using fire to inspire and empower people\, from ranchers and scientists to agency leaders and young women\, and everyone in between. \nRegister Here

SUMMARY:Partner Webinar: Towards Advancing the Prediction of Wildland Fuels Combustion through Detailed Kinetics
DESCRIPTION:5:00 PM ET April 30\, 2024 \nHosted by the California Fire Science Exchange \nAbstract: Wildfires are becoming an increasing issue\, raising concern about direct infrastructure and property damage as well as indirect effects related to their emissions. In this context\, a fundamental understanding of the burning processes of wildland fuels is crucial for the modeling and prediction of both fire behavior as well as related emissions. Current fuel consumption parameterizations used in wildfire models usually oversimplify fuel consumption processes\, such as flaming and smoldering combustion regimes\, and fuel properties\, like fuel elements’ size and moisture content. In this seminar\, a physics-based modeling framework developed to describe biomass combustion and emissions will be presented. Biomass is represented through its fundamental constituents\, such as lignin\, cellulose\, hemicellulose\, water\, and extractives. A detailed reaction kinetic model is coupled with a multi-region single-particle model and is adopted to investigate the process of biomass degradation\, including char oxidation. The validation of the modeling framework with experimental data from literature is performed at various scales\, including thermogravimetric experiments and particle-scale experiments of pyrolysis and combustion. Additionally\, preliminary results of its applicability for the construction of detailed parameterizations for large-scale wildfire applications\, such as WRF-SFIRE coupled atmosphere-fire model\, will be discussed. \nPresenter: Chiara Saggese received her PhD in Industrial Chemistry and Chemical Engineering from Politecnico of Milan in 2015. After working as a postdoctoral fellow on experiments and kinetic modeling of real fuel combustion chemistry and emissions at Stanford University\, she joined the Reaction Dynamics Group in Lawrence Livermore National Laboratory in 2019. Her research activity spans from the development of kinetic models of conventional and sustainable fuels to the kinetic modeling of pollutants formation in combustion processes. Within the current transition to a decarbonized transportation system\, she is focusing on modeling soot formation from sustainable aviation fuels. Lately\, her research focus has expanded to the investigation of wildland fuels combustion and emissions to inform sub-models present in large-scale wildfire applications. \nRegister here.
