We highlight the importance of island research that aims to achieve sustainability transitions. All too often, developmental priorities are largely defined by economic policy imperatives, and island research either ignores or masks such normative connotations. This article reports on ten years of transdisciplinary socioecological research on the Greek island of Samothraki. We sequentially: (i) introduce socioecological thinking and the conceptual framework of social ecology, and show how this is operationalised and applied on this case study, and (ii) highlight the importance of a transdisciplinary research approach, in promoting island sustainability. We conclude with a plea for more transformative research and citizen research in the direction of sustainability within island studies.
