Many Small Island Developing States (SIDS) are experiencing a nutrition transition, wherein high prevalence of malnutrition co-occurs with growing rates of diet-related non-communicable diseases. Sustainably managed and accessible aquatic foods can serve as a rich and bioavailable source of nutrients, helping communities achieve healthy diets and meet key sustainable development goals (e.g., SDG 1 No Poverty, SDG 2 Zero Hunger, and SDG 14 Life Below Water). However, to properly harness aquatic food systems in nutrition interventions, we must first understand aquatic food’s role in nutrient intake and adequacy. Here, using a nationally representative survey from Kiribati, we quantify the contribution of aquatic foods to nutrient intake and adequacy, and examine the spatial variability in nutrient intake adequacies. We find aquatic foods are the main contributors of most nutrients we examined, providing > 75% of vitamin B12, retinol, and heme iron, > 50% of niacin and total vitamin A, and > 25% of protein, vitamin E, potassium, and total iron consumed. Consumption of aquatic foods contributes to meeting key nutrient adequacies (e.g., niacin) and provides complete adequacy for vitamin B12 and protein. However, despite high aquatic food consumption, we find high levels of nutrient inadequacies (11 of the 17 nutrients with dietary reference intakes). Overall, our study quantifies the nutritional importance of aquatic foods in an emblematic SIDS, emphasizing their vulnerability to declining aquatic resources. We also highlight the need for cross-scale context-specific targeted nutrition interventions, even when aquatic food consumption is high, to enable SIDS to meet key SDGs. 

Abstract Both the ecological and social dimensions of fisheries are being affected by climate change. As a result, policymakers, managers, scientists and fishing communities are seeking guidance on how to holistically build resilience to climate change. Numerous studies have highlighted key attributes of resilience in fisheries, yet concrete examples that explicitly link these attributes to social‐ecological outcomes are lacking. To better understand climate resilience, we assembled 18 case studies spanning ecological, socio‐economic, governance and geographic contexts. Using a novel framework for evaluating 38 resilience attributes, the case studies were systematically assessed to understand how attributes enable or inhibit resilience to a given climate stressor. We found population abundance, learning capacity, and responsive governance were the most important attributes for conferring resilience, with ecosystem connectivity, place attachment, and accountable governance scoring the strongest across the climate‐resilient fisheries. We used these responses to develop an attribute typology that describes robust sources of resilience, actionable priority attributes and attributes that are case specific or require research. We identified five fishery archetypes to guide stakeholders as they set long‐term goals and prioritize actions to improve resilience. Lastly, we found evidence for two pathways to resilience: (1) building ecological assets and strengthening communities, which we observed in rural and small‐scale fisheries, and (2) building economic assets and improving effective governance, which was demonstrated in urban and wealthy fisheries. Our synthesis presents a novel framework that can be directly applied to identify approaches, pathways and actionable levers for improving climate resilience in fishery systems.
