Blue food demand across geographic and temporal scales

Naylor, R.L., A. Kishore, U.R. Sumaila, I.Issifu, B.P. Hunter, B. Belton, S.R. Bush, L. Cao, S. Gelcich, J.A. Gephart, C.D. Golden, M. Jonell, J. Z. Koehn, D.C. Little, S. H. Thilsted, M. Tigchelaar and B. Crona . 2021. Blue food demand across geographic and temporal scales. Nature Communications 12: article 5413.

Numerous studies have focused on the need to expand production of ‘blue foods’, defined as aquatic foods captured or cultivated in marine and freshwater systems, to meet rising population- and income-driven demand. Here we analyze the roles of economic, demographic, and geographic factors and preferences in shaping blue food demand, using secondary data from FAO and The World Bank, parameters from published models, and case...

Compound climate risks threaten aquatic food system benefits

Tigchelaar, M., W.W.L. Cheung, E.Y. Mohammed, M.J. Phillips, H.J. Payne, E.R. Selig, C.C.C. Wabnitz, M.A. Oyinlola, T.L. Frölicher, J.A. Gephart, C.D. Golden, E.H. Allison, A. Bennett, L. Cao, J.

Aquatic foods from marine and freshwater systems are critical to the nutrition, health, livelihoods, economies and cultures of billions of people worldwide, but climate-related hazards may compromise their ability to provide these benefits. Here, we estimate national-level aquatic food system climate risk using an integrative food systems approach that connects climate hazards impacting marine and freshwater capture fisheries and aquaculture to their contributions to sustainable...

Environmental performance of blue foods

Gephart, J.A., P.J.G. Henriksson, R.W.R. Parker, A. Shepon, K. D. Gorospe, K. Bergman, G. Eshel, C.D. Golden, B.S. Halpern, S. Hornborg, M. Jonell, M. Metian, K. Mifflin, R. Newton, P. Tyedmers, W. Zhang, F. Ziegler and M. Troell. 2021. Environmental performance of blue foods. Nature 597:360–365.

Fish and other aquatic foods (blue foods) present an opportunity for more sustainable diets1,2. Yet comprehensive comparison has been limited due to sparse inclusion of blue foods in environmental impact studies3,4 relative to the vast diversity of production5. Here we provide standardized estimates of greenhouse gas, nitrogen, phosphorus, freshwater and land stressors for species groups covering nearly three quarters of global production. We find that...

Interventions for improving the productivity and environmental performance of global aquaculture for future food security

Henriksson, P.J.G., M. Troell, L.K. Banks, B. Belton, M.C.M. Beveridge, H. KLinger, N. Pelletier, J. Phillips, N. Tran. 2021. Interventions for improving the productivity and environmental performance of global aquaculture for future food security. One Earth 4(9):1220-1232.

Aquatic foods are increasingly being recognized as having an important role to play in an environmentally sustainable and nutritionally sufficient food system. Proposals for increasing aquatic food production often center around species, environments, and ambitious hi-tech solutions that mainly will benefit the 16% of the global population living in high-income countries. Meanwhile, most aquaculture species and systems suffer from large performance gaps, meaning that targeted...

Building social-ecological system resilience to tackle antimicrobial resistance across the One Health spectrum: Protocol for a mixed methods study

Lambraki I.A., S.E. Majowicz, E.J. Parmley, D. Wernli, A. Léger, T. Graells, M. Cousins, S. Harbarth, C. Carson, P. Henriksson, M. Troell and P.S. Jørgensen. 2021. Building social-ecological system resilience to tackle antimicrobial resistance across the One Health spectrum: Protocol for a mixed methods study. JMIR Res Protoc 10(4):e24378.

Background: Antimicrobial resistance (AMR) is an escalating global crisis with serious health, social, and economic consequences. Building social-ecological system resilience to reduce AMR and mitigate its impacts is critical. Objective: The aim of this study is to compare and assess interventions that address AMR across the One Health spectrum and determine what actions will help to build social and ecological capacity and readiness to sustainably...

The synergistic impacts of anthropogenic stressors and COVID-19 on aquaculture: A current global perspective

Sarà, G., M.C. Mangano et al. 2021. The synergistic impacts of anthropogenic stressors and COVID-19 on aquaculture: A current global perspective. Reviews in Fisheries Science & Aquaculture Online First 1-13.

The rapid, global spread of COVID-19, and the measures intended to limit or slow its propagation, are having major impacts on diverse sectors of society. Notably, these impacts are occurring in the context of other anthropogenic-driven threats including global climate change. Both anthropogenic stressors and the COVID-19 pandemic represent significant economic challenges to aquaculture systems across the globe, threatening the supply chain of one of...

Time to rethink trophic levels in aquaculture policy

Cottrell, R.S., M. Metian, H.E. Froehlich, J.L. Blanchard, N. Sand Jacobsen, P.B. McIntyre, K.L. Nash, D.R. Williams, L. Bouwman, J.A. Gephart, C.D. Kuempel, D.D. Moran, M. Troell and B.S. Halpern. 2021. Time to rethink trophic levels in aquaculture policy. Reviews in Aquaculture 13(3): 1583-1593.

Aquaculture policy often promotes production of low-trophic level species for sustainable industry growth. Yet, the application of the trophic level concept to aquaculture is complex, and its value for assessing sustainability is further complicated by continual reformulation of feeds. The majority of fed farmed fish and invertebrate species are produced using human-made compound feeds that can differ markedly from the diet of the same species...

Characterizing antibiotics in LCA—a review of current practices and proposed novel approaches for including resistance

Nyberg, O., A. Rico, J.B. Guinée and P.J.G. Henriksson. 2021. Characterizing antibiotics in LCA—a review of current practices and proposed novel approaches for including resistance. The International Journal of Life Cycle Assessment 26:1816–1831.

Purpose With antibiotic resistance (ABR) portrayed as an increasing burden to human health, this study reviews how and to what extent toxicological impacts from antibiotic use are included in LCAs and supplement this with two novel approaches to include ABR, a consequence of antibiotic use, into the LCA framework. Methods We review available LCA studies that deal with toxicological aspects of antibiotics to evaluate how...
