Southwest CASC

Over the past four decades, annual area burned has increased significantly in California and across the western USA. This trend reflects a confluence of intersecting factors that affect wildfire regimes. It is correlated with increasing temperatures and atmospheric vapour pressure deficit. Anthropogenic climate change is the driver behind much of this change, in addition to influencing other climate-related factors, such as compression of the winter wet season. These climatic trends and associated increases in fire activity are projected to continue into the future. Additionally, factors related to the suppression of the Indigenous use of fire, aggressive fire suppression and, in some cases, changes in logging practices...

The Conserving Climate Change Refugia for the Mojave Ecosystem workshop was held virtually via zoom on Wednesday, December 9, 2019, using funding from the Southwest Climate and the Northeast Climate Adaptation Science Centers (SW and NE CASCs). The objectives of this workshop were to bring together natural resource managers and researchers to 1) learn about current work in the Mojave ecoregion related to climate adaptation, 2) prioritize focal species/ecosystems for climate change refugia conservation/funding, and 3) identify research gaps, all in service of operationalizing climate change adaptation strategies in the Mojave ecoregion. The meeting began with presentations by researchers and resource managers who...

Cycles of Renewal: Returning Good Fire to the Chumash Homelands
Fire has always been a part of life in southern California. Climate change and current fire management practices have led to catastrophic losses and impacts to human health, infrastructure and ecosystems, as seen, for example, in the 2018 Montecito debris flow. Indigenous wisdom instructs that rather than suppressing fire, we should seek to be in good relationship with fire. This project centers the voices of Chumash people by revitalizing their good relationship with fire in Chumash homelands. This revitalization comes at a critical time for both fire management and revitalization of Indigenous cultural burning practices in the southwest. The project will enable the recovery and documenting of Chumash knowledge...

Rendering High-Resolution Hydro-Climatic Data for Southern California
Natural resource managers and researchers often need long-term averages of historical and future climate scenarios for their study area yet may not have the resources to make these summaries. This project will provide high quality, detailed maps of historical and projected future climate and hydrologic conditions for California and a finer scale version for southern California. The project will also assess the feasibility of expanding these reference data to the southwestern US and identify the most suitable online data portals for the public to view and analyze the data in support of local initiatives. The map products can be used to assess the impacts of ongoing climate change and to develop climate adaptation...
