Abstract

Coastal communities around the world face a growing threat from rising sea levels, more severe storms, and droughts. To address these challenges, many have turned to natural and nature-based features (NNBF) as a means of reducing hazard exposure while also providing important environmental and social benefits. Despite their many advantages, however, a significant number of waterfront property owners continue to opt for hardened infrastructure to protect their shorelines. Kiera O'Donnell investigated the aftermath of two hurricanes to gain insight into the dynamics between people and their environment in the context of shoreline protection. While both communities surveyed showed an awareness of the protective properties of NNBF, a majority chose hardened infrastructure as their preferred option. Her study sheds new light on the complex factors that influence decision-making in the face of environmental hazards, and highlights the importance of understanding these dynamics to ensure effective and sustainable solutions.
