A systematic review of the climatic impacts, diverse adaptation pathways and multiple adaptation barriers for inland aquaculture
Su, J., M. Tigchelaar, B. Belton, Q. Wang, C. M. Rossignoli, E. H. Allison, M. Troell, and A. Gasparatos. 2026. A systematic review of the climatic impacts, diverse adaptation pathways and multiple adaptation barriers for inland aquaculture. Nature Food .
Climate change is increasingly constraining inland aquaculture, a critical contributor to global food and nutrition security. Here we systematically review literature in English and Chinese to synthesize climate-related impacts from 84 peer-reviewed sources to identify adaptation options and map pathways across the aquaculture value chain. We document diverse, interacting stressors affecting production systems and livelihoods, alongside 53 potential adaptation options spanning management, technology and governance....
Feasibility, co-benefits, and trade-offs of climate mitigation and adaptation strategies in blue food systems
Wong, A., M. Jonell, M. Tigchelaar, M. Troell, C. C. C. Wabnitz, E. H. Allison, K. Deering, P. J. G. Henriksson, K. M. Kleisner, J. Z. Koehn, J. G. Mason, M. S. Schutter, and E. R. Selig. 2026. Feasibility, co-benefits, and trade-offs of climate mitigation and adaptation strategies in blue food systems. Environmental Research: Food Systems 3:035007.
Blue food—aquatic organisms fished or farmed in marine and freshwater areas, including fish, shellfish, and aquatic plants—make critical contributions to nutrition, livelihoods, and economies, and can have lower carbon footprints than other animal-source foods. While blue foods are increasingly discussed as part of climate change mitigation and adaptation, climate change also affects the feasibility, performance, and equity outcomes of blue food strategies, and evaluations of...
Fish as food or feed? Aligning FIFO with LCA and food system objectives.
Malcorps, W., R. Newton, S. Horn, B. Kok, M. Troell, and D. C. Little. 2026. Fish as food or feed? Aligning FIFO with LCA and food system objectives.. Reviews in Fisheries Science & Aquaculture .
Aquatic animals contain essential and unique nutrients for human health. They are produced from a continuum, rather than a dichotomy, of aquaculture and fisheries, from which, it is crucial to maximize nutrient availability for human populations. Marine ingredients (primarily fishmeal and fish oil) have been a critical part of carnivorous fish diets, for fish performance, and delivering omega-3 fatty acids to consumers, but have received...
Nutrient bioavailability is the missing ingredient connecting food systems to nutrition security and environmental sustainability
Nicholas, K. M., A. Tone , T. Beal, J. Zamborain-Mason, H. Eneroth, V. Öhrvik , M. Troell, and C. D. Golden. 2026. Nutrient bioavailability is the missing ingredient connecting food systems to nutrition security and environmental sustainability. The American Journal of Clinical Nutrition 123(5).
Increasing attention has focused on the capacity of current global food systems to provide accessible, affordable, and sustainable food to a growing human population, particularly amid ongoing climate and environmental changes. Concerns about the dysfunction of the global food system have led to the development of several initiatives to estimate current and predict future global nutrient supplies based on various climate, production, and demand scenarios....
Global nutritional equity of fishmeal and aquaculture trade flows
Elsler, L. G., J. A. Gephart, J. Zamborain-Mason, T. Cashion, M. Troell, R. L. Naylor, R. Agrawal Bejarano, and C. D. Golden. 2026. Global nutritional equity of fishmeal and aquaculture trade flows. PNAS 123(7).
Aquaculture, the single fastest growing food sector, is central to achieving key SustainableDevelopment Goals (e.g., SDG 2: Zero Hunger). Linking the nutrient compositionof >2,800 aquatic species with >2 million fishmeal and farmed fish transactions ininternational aquatic food trade between 2015 and 2019, we examined aquaculture’snutritional flows and distributional equity. We found that aquaculture provided adequateintakes for nearly a quarter of a million individuals, on average,...
Efficient and sustainable management of shared fisheries in Thailand: Self-governance or regulation?
Jarungrattanapong, R. and T. Lindahl. 2026. Efficient and sustainable management of shared fisheries in Thailand: Self-governance or regulation?. Ecological Economics 246(109019).
Artisanal fisheries are significant for poverty alleviation, but they are severely threatened by overfishing and climate change effects. Governance solutions can be hard to find when their implementation and success depend on both social and ecological contexts. In this study, we aim to increase our understanding of behavioral strategies adopted by artisanal fisheries under different types of governance scenarios using a field experiment in the...
Accountability in collaborative settings: understanding inter-corporate sustainability initiatives
Sobkowiak, M., J. Bebbington, R. Blasiak, C. Folke, and H. Österblom. 2025. Accountability in collaborative settings: understanding inter-corporate sustainability initiatives. Accounting Forum 50(1):72-103.
As corporations have come to recognise their role in shaping the biosphere, there has been an increase in inter-corporate cooperation, whereby corporations come together to address issues of common concern. The rationale for developing a collective approach arises from a realisation that “wicked” problems are beyond the capacity of any one organisation to tackle. At the same time, although inter-corporate collaborations exist in the practice...
Broadening the sustainable seafood movement—systemic and enabling approaches to transform blue food
Jonell, M., A. Blandon, J. M. C. Feine, and S. Käll. 2025. Broadening the sustainable seafood movement—systemic and enabling approaches to transform blue food. Environmental Research: Food Systems 2(3):035009.
The global appetite for environmentally sustainable and just seafood is expected to grow in coming decades. However, the sustainable seafood movement, including private governance tools like certifications and recommendation lists has yet to transform fisheries and aquaculture on a large scale. At the same time, alternative voluntary governance approaches have taken shape, each aiming to guide production and consumption toward greater sustainability. In this article,...
What does “sustainable seafood” mean to seafood system actors in Japan and Sweden?
Blandon, A., M. Jonell, H. Ishihara, and A. Zabala. 2025. What does “sustainable seafood” mean to seafood system actors in Japan and Sweden?. Ambio 54:1010–1025.
“Sustainability” can mean different prioritisations of society, environment and economy to different people. As one of the largest globally traded food commodities, for seafood, these differences could have large implications. The study captures different understandings of “sustainable seafood” among 29 key actors along the seafood supply chain—government, NGOs, industry bodies, retailers and producers—using a novel cross-country application of Q method in Japan and Sweden. Sweden,...
Aquaculture requires special consideration in National Action Plans for Antimicrobial Resistance
Desbois A. P., L. A. Brunton, P. J. G. Henriksson, O. Luthman, M. Troell, and D. M. Green. 2025. Aquaculture requires special consideration in National Action Plans for Antimicrobial Resistance. Science of The Total Environment 958:177785.
Antimicrobial resistance (AMR) demands collective action to reduce and mitigate its threats. The Quadripartite collaboration of the World Health Organization (WHO), Food and Agriculture Organization of the United Nations (FAO), United Nations Environment Programme (UNEP) and World Organization for Animal Health (WOAH) has led development and implementation of National Action Plans (NAPs) that describe approaches each country will take to tackle AMR. All antimicrobial users...
