Arctic coastal hazards – like erosion, flooding, and permafrost thaw - are intensifying due to climate warming creating social and economic impacts and risks for coastal communities. In this session, we discuss the co-production of knowledge and tools for forecasting coastal hazards and risks as well as the generation of scenarios for communicating these hazards and risks. Communities, researchers, and agencies are collaboratively developing coastal monitoring programs that generate data to understand coastal change and support hazard forecasting. Through this effort, a new hazard, usteq (Yup’ik word meaning catastrophic land collapse) was identified and included in the 2018 Alaska Hazard Mitigation Plan. We are also collaborating in the collection of data to quantify the social and economic impacts of coastal hazards. The collaborative effort to define and forecast coastal hazards and risks is setting the stage for wise and long-term sustainable adaptation to the climate change challenge.
