The food system is a major driver of climate change, changes in land use, depletion of freshwater resources, and pollution of aquatic and terrestrial ecosystems through excessive nitrogen and phosphorus inputs. Here we show that between 2010 and 2050, as a result of expected changes in population and income levels, the environmental effects of the food system could increase by 50–90% in the absence of technological changes and dedicated mitigation measures, reaching levels that are beyond the planetary boundaries that define a safe operating space for humanity. We analyse several options for reducing the environmental effects of the food system, including dietary changes towards healthier, more plant-based diets, improvements in technologies and management, and reductions in food loss and waste. We find that no single measure is enough to keep these effects within all planetary boundaries simultaneously, and that a synergistic combination of measures will be needed to sufficiently mitigate the projected increase in environmental pressures.

Blue foods, sourced in aquatic environments, are important for the economies, livelihoods, nutritional security and cultures of people in many nations. They are often nutrient rich1, generate lower emissions and impacts on land and water than many terrestrial meats2, and contribute to the health3, wellbeing and livelihoods of many rural communities4. The Blue Food Assessment recently evaluated nutritional, environmental, economic and justice dimensions of blue foods globally. Here we integrate these findings and translate them into four policy objectives to help realize the contributions that blue foods can make to national food systems around the world: ensuring supplies of critical nutrients, providing healthy alternatives to terrestrial meat, reducing dietary environmental footprints and safeguarding blue food contributions to nutrition, just economies and livelihoods under a changing climate. To account for how context-specific environmental, socio-economic and cultural aspects affect this contribution, we assess the relevance of each policy objective for individual countries, and examine associated co-benefits and trade-offs at national and international scales. We find that in many African and South American nations, facilitating consumption of culturally relevant blue food, especially among nutritionally vulnerable population segments, could address vitamin B12 and omega-3 deficiencies. Meanwhile, in many global North nations, cardiovascular disease rates and large greenhouse gas footprints from ruminant meat intake could be lowered through moderate consumption of seafood with low environmental impact. The analytical framework we provide also identifies countries with high future risk, for whom climate adaptation of blue food systems will be particularly important. Overall the framework helps decision makers to assess the blue food policy objectives most relevant to their geographies, and to compare and contrast the benefits and trade-offs associated with pursuing these objectives.

Background: A food system transformation is needed to address food and nutrition security, minimise impacts on planetary health, reduce climate change emissions, and contribute to equity, diversity, and the Sustainable Development Goals.
Scope and approach: This paper summarizes findings of the European Commission's High Level Expert Group on Food Systems Science, which reviewed obstacles that prevent food systems policy from achieving society-wide impacts. These barriers include knowledge and translation gaps in food-related science-policy-interfaces (SPIs), insufficient attention to the priorities of diverse stakeholders, and a failure to adequately consider equity, diversity, political economy, and societal engagements.
Key findings & conclusions: Three potential pathways can ensure science and policy support food systems transformation: (1) Adapt the current SPI landscape with extra resources and a wider mandate to ensure coordinated action across the full food system, (2) Enhance the current policy landscape with a range of multisectoral taskforces designed to fulfill specific functions such as creating an enhanced food systems data portal, and (3) Establish a “network of networks” to provide both global coordination as well as organize defined agendas at global through to regional scales.
In embarking on these pathways, a revised science-policy-society landscape (SPSIs) should deliver the following core functions: (1) Engage and empower multi-stakeholder dialogue; (2) Build capacity at multiple scales to translate evidence into tangible real-world outcomes; (3) Ensure access to openly accessible data for the entire food system; (4) Use models, forecasts, and scenario building exercises to explore the potential future of food systems; (5) Produce assessment reports and policy publications; and (6) Establish fora for diplomacy that will be empowered to create standards set targets and establish policy.
