Perceptions 3. Actions Related to flood and heat hazards Impacted by... flooding* *statistically significant differences extreme heat Perception of... flood risk* *statistically significant differences heat risk* *statistically significant differences Actions taken... To mitigate flood risk* *statistically significant differences To mitigate heat risk What influences actions to reduce hazard risk? • Social capital is important for both – Positive and statistically significant for heat and flood • Neighborhood cohesion more important for flood actions • Individual/Household "networks" more important for heat actions • Hispanic residents more proactive regarding heat • Black residents less active with flood actions Image taken from LA County Community Disaster Resilience http://www.laresilience.org/ Next Steps Share our survey instrument with the committee Can look at questions from a variety of indicators • • • Ongoing heat research with the Office of Sustainability (funded by NOAA) • Dashboard for climate, heat and air quality (see next slide) Publishing briefs on a variety of themes in the Fall Start preparing for 2022 A2SI Survey…with your help! • • Questions & Feedback Patrick Bixler rpbixler@utexas.edu Or Jess Jones Jesjones@utexas.edu
