Abstract

In recent years, climate change has led to an increased frequency, intensity, and severity of several natural hazards such as droughts and floods. Managed retreat, a transformative climate change adaptation strategy, refers to the intentional movement of people and infrastructure out of harm’s way to limit or avoid damages from such extreme events. Managed retreat can be particularly advantageous for regions located within floodplains because risks to the community are mitigated and the land can then be restored so as to be in harmony with its natural floodplain functions. In a successful and effective managed retreat proposal, the solution offered must be sustainable environmentally, socially, and economically. Sound managed retreat proposals also require comprehensive policies that ensure that the rights of all parties affected are upheld. Those who relocate must be guaranteed clean water, nutritious food, and safe housing—all at reasonable cost. Truly equitable and sustainable managed retreat calls for dialog and collaboration between community members and leaders, politicians, city planners, engineers, and environmentalists. Engaged committees with diverse perspectives are critical to the success of any managed retreat project. This study seeks to highlight risks and outlines opportunities associated with managed retreat from social, environmental, economic, and legal perspectives. Specifically, to different degrees, we study contrasting retreat strategies employed for villages in Fiji, the city of Houston, and an Arctic Alaskan region—these cases consider cultural disruption that can result from retreat; community engagement in decision-making; and social inequalities experienced by affected parties that become part of ill-advised managed retreat programs.
