Risk perceptions are increasingly understood as components of adaptation to climate change and natural hazards. Although several studies have measured the influence of cognitive factors in individuals’ adaptation and perceptions of vulnerability, their impact among businesses is not well understood. Building on models of adaptive capacity and human cognition, this thesis addresses the question: do perceptions of risk influence business owners and managers’ willingness to adapt? An online survey of business owners and managers in Sarasota County, Florida assessed perceived adaptation options, probability and severity of risk, and willingness to adapt proactively to threats of hurricane storm surge intensified by sea-level rise. Spatial variables of physical exposure and previous hurricane experience predicted flood risk perceptions and the number of preparedness measures implemented. Risk perceptions of flood and wind damage did not predict levels of preparedness, indicating a role for the perception of adaptation efficacy in determining adaptive capacity to climate change hazards. This study provides support for targeted risk communication messages that provide place-specific information about risks and adaptation options.
