Islands and islanders are often misrepresented in the climate change discourse, oversimplifying their experiences and interactions with climate change. In reality, islands and islanders have far more complex relationships with climate change. This special thematic section presents eight papers that highlight local responses and localized impacts of climate change on islands, reiterating the importance of considering local community perspectives in small island contexts to overcome simplistic viewpoints. Such perceptions and perspectives are increasingly being recognized as offering a valuable contribution to climate change adaptation, particularly to counter the misrepresentation of small islands as vulnerable or passive, and the disregard for the fact that climate change is a global, as well as continual process. This special thematic section further demonstrates that island research is well placed to address the disproportionate concentration of perspectives and opinions of climate change from the Global North and adds to the calls for increased efforts to give a voice to island communities of all kinds.

Small Island Developing States (SIDS) are now experiencing the local consequences of a changing climate, environment, and society. Nonetheless, climate change research frequently remains at regional or national levels. Without locally grounded data, islanders’ perceived impacts of the changes might not be considered, thereby causing difficulties when policy and practice responses are implemented without accounting for local understandings. To contribute to addressing this gap, this study examines perceptions of climate change and associated environmental and social changes in two SIDS case studies: St. Kitts in the Caribbean Sea and Malé Atoll, Maldives in the Indian Ocean. Through these two case studies, we assess perceptions of changing social and natural environments through a closed-question, face-to-face survey. Our results suggest that in both island case studies, communities perceive environmental changes to be happening that demand negotiation with the social changes of daily life. Results also suggest that perceived climate change impacts are only part of the equation, as social and economic impacts reveal two case studies of changing island societies. While the geographic context in each case study differs, this study reveals the perceived impacts of climate change and social changes at a local level, providing valuable insights and angles for formulating policies and actions to deal with the myriad of social and environmental changes affecting SIDS.

Caribbean islands, like other Small Island Developing States (SIDS), are at the center of the vulnerability debate as current climatic trends predict elevated sea levels and increased frequency of storms, leading to significant challenges for local communities. Caribbean islanders have been exposed to climatic challenges since the initial occupation of the archipelago between five to eight thousand years ago. They have been continually confronted with severe droughts, tropical cyclones, extreme wave events, sea-level changes, and the accompanying impacts. The various phenomena have stimulated island residents both to anticipate and respond to such events, adapting their lifestyles and socio-cultural and political structures and ties across the region over time. In this article, we innovatively combine archaeological and palaeoenvironmental data with longitudinal coastal-erosion data and ethnographic data to further develop and promote sustainable local strategies to mitigate the adverse effects of climate change and increasingly frequent and violent weather events on small-island settings. To find proxies, we first look into the region’s pre-colonial archaeological record. Second, we delve into predictive modeling and the current and future climatic challenges for heritage sites and local coastal communities, as well as related collaborative heritage mitigation efforts. Third, we discuss the contribution of traditional knowledge practices to climate change adaptation. The results show how the long-term perspective and multidisciplinary approach adopted here may lead to realistic solutions to seemingly intractable problems. They also reveal how collaborative projects involving all stakeholders on an equal basis in all phases of research have become a top priority in climate change mitigation and heritage safeguarding.
