Food security, in the context of a rapidly changing climate, is one of the most prominent global challenges facing human societies. Pacific Island Countries and Territories (PICTs) are particularly vulnerable to the adverse effects of climate change, while facing additional stress from globalisation. In order to develop robust adaptation strategies for climate change, this review aimed to take stock of the state of our understanding of food system vulnerability to climate change in the region, and identify the existing analyses that could inform policy and decision-making. Furthermore, this review aimed to determine if empirical research adopted a systems approach, the conceptual importance of which is well-established for ensuring the resilience of human food and nutrition security in the face of unprecedented change. Using keyword searches on the web and scholarly databases, we identified 104 studies from 2010-2022 that looked at the impacts of climate change on some aspect of the food system in at least one PICT. Excluding review studies, we found that the majority of research on climate impacts on food systems in PICTS focused on the biophysical components of food production rather than the complex interactions between the socio-economic and biophysical factors that make up food systems. An incomplete understanding of the impacts from climate change on the whole system can have consequences for the types of adaptation strategies that are pursued. The future of food systems in the Pacific will in part determine the long-term resilience, prosperity, and wellbeing of the Pacific peoples.
