Caribbean Small Island Developing States (SIDS) are among the most vulnerable to climate change, which will have a disproportionate impact on local environments and economies. Whilst there is a growing literature on how Caribbean SIDS can adapt to become more resilient, an issue that has received little attention is with regard to migration as an unplanned response. It is recognised that events such as hurricanes and flooding can lead to internal relocation in the short term, but societal responses to droughts through migration have not generally been investigated. This paper seeks to address this by considering the case of the island of Carriacou, part of the state of Grenada. Carriacou, with its small population, limited land area, and local economy historically based on agriculture, has had a high degree of migration. This is in part a response to limited economic opportunities. Environmental stress, manifest through limited water availability, inappropriate land management, and social conditions, is likely to be exacerbated by climate change and variability. Resultant increases in the frequency and intensity of droughts, in the absence of proactive interventions, are likely to result in non-linear migration, both to Grenada itself and beyond.
