At the heart of this graduate-level seminar is a question: why, despite objective evidence of risks to health, livelihoods, and property from natural hazards and climate change, do individuals often not change their behavior? People’s decisions to protect themselves from risks, hazards, and climate change are complex and multifaceted, influenced by awareness, perception, access to resources, and social norms, among other factors. We will delve into theories and examples to understand individual human behavior regarding risks, hazards, and climate change. The course will help prepare students for applied research and professional positions designing, implementing, and evaluating programs and policies to enable, encourage, and incentivize behavior change to protect the well-being of individuals and households.
