Summary
This integrative policy assessment translates findings from the Blue Food Assessment into four geographically contextualised policy objectives to guide national blue food system strategies. The analysis reveals context-specific contributions: African and South American nations may address micronutrient deficiencies through culturally relevant blue food consumption, whilst Global North nations could reduce cardiovascular disease and ruminant meat emissions through low-impact seafood. The framework identifies high-risk countries requiring climate adaptation and provides decision-makers with tools to compare benefits and trade-offs of competing policy objectives.
UK applicability
The UK, as a Global North nation with high ruminant meat consumption and associated greenhouse gas footprints, may find the framework relevant for assessing moderate seafood consumption as a cardiovascular and climate mitigation strategy. However, UK-specific nutritional vulnerabilities and regional aquaculture feasibility would require country-level application of this global analytical framework.
Key measures
Nutritional adequacy (vitamin B12, omega-3 deficiencies), environmental footprints (greenhouse gas emissions, land and water impacts), economic and livelihood contributions, climate adaptation risk
Outcomes reported
The study assessed four policy objectives for blue foods: ensuring critical nutrient supplies, providing healthy meat alternatives, reducing dietary environmental footprints, and safeguarding blue food contributions under climate change. It evaluated the relevance and trade-offs of each objective for individual countries across nutritional, environmental, economic and justice dimensions.
