How can ecological design principles prevent the erosion of the physical and social framework of low-income coastal communities? A significant portion of the world’s population is concentrated along coastlines. Direct access to the water provides access to a longstanding source of economic prosperity and a psychological connection to natural environments. However, human-influenced climate change has produced hazardous environmental conditions that threaten coastal populations, including many poor, vulnerable communities. Disparities in investment for public services, maintenance, and upkeep increases the vulnerability of these disenfranchised groups that cannot protect themselves. The built and natural environment within this diverse boundary zone between the land and sea must be redeveloped as a self-resilient ecosystem that can protect its inhabitants from climate-induced hazards. This renewal will require holistic approaches that can mitigate contemporary impacts to protect current populations at risk and adapt the built environment to better respond in the future.
