A Systematic Review of Empirical Research on Behavioral Drivers of Households' Flood Risk Adaptation Over Time and Across Regions

Empirical research on households' flood risk adaptation behavior has gained significant attention. While several reviews have already summarized the general progress in this research domain, no study has systematically assessed the progress toward addressing identified research gaps in this field over time and across geographic regions. Therefore, we conducted a systematic review (n = 352) to assess the distribution and scope of empirical studies over time and across regions. Applying content and statistical analyses, we assess the distribution of case studies across countries, regions, and flood risk levels, and the share of studies addressing key research gaps related to methods, theoretical frameworks, behavioral drivers, and adaptation behaviors.
