Abstract

Coastal communities are under pressure to adapt to the increasing impacts of climate change and environmental degradation. One strategy to achieve adaptation goals is to deploy hard structures and nature -based solutions that can help reduce damages from flooding, storm surge, and sea level rise in coastal areas. Understanding how local communities perceive and value these measures helps local authorities follow strategies that not only increase efficiency, but also garner public support. In this paper, we used Miami -Dade County as a case study to establish public preferences and trade-offs across hard structures and nature -based solutions and their physical characteristics to address coastal risk reduction: specifically, seawalls and mangroves. By applying a discrete choice experiment, we showed that respondents are generally in favor of deploying any coastal measures, with a higher willingness -to -pay for nature -based solutions over hard structures. We also found that the same respondents identify the length of protected coastline as a valuable feature of these coastal measures. Our findings inform ongoing plans and policies for coastal adaptation, particularly the deployment of nature -based solutions, and also illustrate the importance of including public input in the decision -making process of coastal management policy.
