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,...

Fuel use intensity of hilsa fisheries in the lower Meghna River estuary of Bangladesh

Zaman, A.U., P.J.G. Henriksson, and A. Al Mamun. 2023. Fuel use intensity of hilsa fisheries in the lower Meghna River estuary of Bangladesh. Fisheries Research 263:106684.

Among the species caught by small-scale fisheries in Bangladesh, hilsa (Tenualosa ilisha) is the most important by volume and of great cultural importance. Hilsa fishing boats have over the last decade been mechanized, enabling longer trips and larger hauls. This development has, however, also resulted in increased fishing pressure and increased reliance on fossil fuels. This study estimates the fuel use intensity (FUI) of hilsa fishing, calculated as fuel...

Reframing the local-global food systems debate through a resilience lens

Wood, A., C. Queiroz, L. Deutsch, B. González-Mon, M. Jonell, L. Pereira, H. Sinare, U. Svedin, and E. Wassénius. 2023. Reframing the local-global food systems debate through a resilience lens. Nature Food 4:22-29.

Despite the growing knowledge that food system solutions should account for interactions and drivers across scales, broader societal debate on how to solve food system challenges is often focused on two dichotomous perspectives and associated solutions: either more localized food systems or greater global coordination of food systems. The debate has found problematic expressions in contemporary challenges, prompting us to revisit the role that resilience...

Digital technology and energy sustainability: Recent advances, challenges, and opportunities

Wei, C., C.Z. Li, A. Löschel, S. Managi, and T. Lundgren. 2023. Digital technology and energy sustainability: Recent advances, challenges, and opportunities. Resources, Conservation and Recycling 190:106803.

Digitalization and sustainability represent two global mainstreams, which affect many dimensions of economic activity and daily life. However, their interaction remains still underexploited with different synergies and tradeoffs between these goals. This Virtual Special Issue (VSI) entitled “Digital technology and energy sustainability: impacts and policy needs” presents recent research on the nexus between digital technology and energy sustainability. This editorial introduces seven recent studies on...

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...
