Troell, M., C. Hurd, T. Chopin, B.A. Costa-Pierce, and M.J. Costello. 2024. Seaweeds for carbon dioxide removal (CDR)– Getting the science right. PLOS Climate 3(3): e0000377.

Aquaculture governance: five engagement arenas for sustainability transformation

Partelow, S. et al. 2023. Aquaculture governance: five engagement arenas for sustainability transformation. Current Opinion in Environmental Sustainability 65:101379.

A greater focus on governance is needed to facilitate effective and substantive progress toward sustainability transformations in the aquaculture sector. Concerted governance efforts can help move the sector beyond fragmented technical questions associated with intensification and expansion, social and environmental impacts, and toward system-based approaches that address interconnected sustainability issues. Through a review and expert-elicitation process, we identify five engagement arenas to advance a governance agenda for aquaculture sustainability...

Transforming sustainable aquaculture by applying circularity principles

Chary, K., A-J. van Riel, A. Muscat, A. Wilfart, S. Harchaoui, M. Verdegem, R. Filgueira, M. Troell, P.J.G. Henriksson, I.J.M. de Boer, and G.F. Wiegertjes. 2023. Transforming sustainable aquaculture by applying circularity principles. Reviews in Aquaculture 16(2):656-673.

A circular economy is considered one way to reduce environmental impacts of human activities, by more efficient use of resources and recovery, resulting in less waste and emissions compared to linear take-make-dispose systems. Muscat et al. developed five ecological principles to guide biomass use towards a circular economy. A few studies have demonstrated environmental benefits of applying these principles to land-based food systems, but to...

Perspectives on aquaculture’s contribution to the Sustainable Development Goals for improved human and planetary health

Troell, M., B. Costa-Pierce, C. Stead, R.S. Cottrell, C. Brugere, A.K. Farmery, D. Little, Å. Strand, R. Pullin, D. Soto, M. Beveridge, K. Salie, J. Dresdner, P. Moraes-Valenti, J. Blanchard, P. James, R. Yossa, E. Allison, C. Devaney, and U. Barg. 2023. Perspectives on aquaculture's contribution to the Sustainable Development Goals for improved human and planetary health. Journal of the World Aquaculture Society 54(2):251-342.

The diverse aquaculture sector makes important contributions toward achieving the Sustainable Development Goals (SDGs)/Agenda 2030, and can increasingly do so in the future. Its important role for food security, nutrition, livelihoods, economies, and cultures is not clearly visible in the Agenda 21 declaration. This may partly reflect the state of development of policies for aquaculture compared with its terrestrial counterpart, agriculture, and possibly also because...

The vital roles of blue foods in the global food system

Leape, J. et al. 2023. The vital roles of blue foods in the global food system. In: von Braun, J., Afsana, K., Fresco, L.O., Hassan, M.H.A. Science and Innovations for Food Systems Transformation. Springer, Cham, Switzerland. Pp. 401-420.

Blue foods play a central role in food and nutrition security for billions of people and are a cornerstone of the livelihoods, economies, and cultures of many coastal and riparian communities. Blue foods are extraordinarily diverse, are often rich in essential micronutrients and fatty acids, and can be produced in ways that are more environmentally sustainable than terrestrial animal-source foods. Yet, despite their unique value,...

Four ways blue foods can help achieve food system ambitions across nations

Crona, B.I. et al. 2023. Four ways blue foods can help achieve food system ambitions across nations. Nature 616:104-112.

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...

Blue Forests – A Review of Carbon Offset Strategies with Seaweed Aquaculture – Feasibility, Current Knowledge, and Suggestions for Future Research

O’Dell, A. et al. 2023. Blue Forests - A Review of Carbon Offset Strategies with Seaweed Aquaculture – Feasibility, Current Knowledge, and Suggestions for Future Research. Report number: 20230202. Scottish Association for Marine Science (SAMS) and Scottish Government.

In September 2022, a group of international collaborators gathered from six European countries (hereby referred to as the ‘working group’) to take part in a workshop at the Scottish Association for Marine Science (SAMS), Oban. The workshop was funded as part of Marine Scotland’s Blue Carbon International Policy Challenge (BCIPC). The main aim of the workshop was to produce a document outlining the potential for...

Sjömatslandet Sverige – Vart är vi på väg? (Seafood Sweden – Where are we going?)

Henriksson, P.J.G., M. Troell, M. Jonell, F. Ziegler, S. Hornborg, and K. Bergman. 2023. Sjömatslandet Sverige – Vart är vi på väg? (Seafood Sweden – Where are we going?). SeaWin Policy Brief no. 7, SeaWin .

Sveriges självhushållningsgrad av sjömat är för närvarande låg, men det finns potential för att öka inhemsk produktion och samtidigt öka sjömatens roll för omställning till ett mer hållbart livsmedelssystem. För att möjliggöra detta krävs att sjömatsbranschen, dagligvaruhandeln och konsumenter vågar utmana sina vanor, samt att myndigheter tar ett bredare systemperspektiv och planerar långsiktigt.

Factors impacting antimicrobial resistance in the South East Asian food system and potential places to intervene: A participatory, One Health study

Lambraki, I.A., C.V. Mohan, M. Cousins, T. Graells, A. Léger, P.J.G. Henriksson, M.F. Troell, S. Harbarth, D. Wernli, P.S. Jørgensen, C.A Carson, E.J Parmley and S.E Majowicz. 2023. Factors impacting antimicrobial resistance in the South East Asian food system and potential places to intervene: A participatory, One Health study. Frontiers in Microbiology 13.

Background: With AMU projected to increase, South East Asia (SEA) is at high risk of experiencing disproportionate health, social, and economic burdens due to antimicrobial resistance (AMR). Our objective was to identify factors influencing AMR in SEA’s food system and places for intervention by integrating the perspectives of experts from the region to inform policy and management decisions. Materials and methods: We conducted two 6.5 h workshops and...
