Habitability – a Method for Viable and Sustainable Island Communities

Assessing the sustainability of small communities presents unique challenges. However, small islands and archipelagic communities offer ideal study environments due to their spatial limitations. The concept of habitability, adapted from the Agenda 2030 framework, is specifically tailored to suit the context of small island societies. This method is grounded in both scientific research and citizen science conducted by island residents, providing a comprehensive assessment of the island’s current habitability status. Key questions include: What are the challenges and opportunities for island communities in addressing demographic imbalances and depopulation? Is
the island open and attractive to new residents? What is the quality of services and infrastructure available? How can the community build resilience against threats such as climate change and military insecurity? Drawing on all dimensions of sustainable development, the habitability method evaluates seven thematic areas through 45 indicators. These indicators reveal how sustainable, viable, and liveable the island community is.
