Coastal rural communities worldwide face many challenges not only related to climate change but also extreme events, environmental degradation, population growth or aging, and conflict usage of the ecosystem. Historically, the economies of coastal communities have been based on the exploitation of natural resources, thus shaping their socio-economic development. This has led to some limitations in the way these communities can now adapt to climate change. In Canada, coastal communities are increasingly dealing with climate change consequences. Sea level rise, coastal erosion, and increasing frequency in storm surges threaten the fragility of both natural and human systems. Various approaches have been used to try to reduce the vulnerability and improve the adaptive capacity of communities. One approach, promoted by many organizations including the United Nations, is ecosystem-based adaptation. This approach is part of the series of nature-based solutions that help social-ecological systems become more resilient; by promoting biodiversity conservation and ecosystem services, this approach also relates to principles of community engagement and supports adaptive governance and social inclusion. This paper describes and analyzes these principles and considers strategies for ensuring community engagement. Combining ecosystem-based adaptation with a strong community engagement can enhance the long-term sustainability of the social-ecological system.
