Evolving Perspectives of Stewardship in the Seafood Industry

Blasiak, R., A. Dauriach, J-B. Jouffray, C. Folke, H. Österblom, J. Bebbington, F. Bengtsson et. al.. 2021. Evolving Perspectives of Stewardship in the Seafood Industry. Frontiers in Marine Science  09 June 2021.

Humanity has never benefited more from the ocean as a source of food, livelihoods, and well-being, yet on a global scale this has been accompanied by trajectories of degradation and persistent inequity. Awareness of this has spurred policymakers to develop an expanding network of ocean governance instruments, catalyzed civil society pressure on the public and private sector, and motivated engagement by the general public as...

A 20-year retrospective review of global aquaculture

Naylor R.L., R. W. Hardy, A. H. Buschmann, S. R. Bush, L. Cao, D. H. Klinger, D: C. Little, J. Lubchenco, S. E. Shumway and M. Troell. 2021. A 20-year retrospective review of global aquaculture. Nature 591:551–563.

The sustainability of aquaculture has been debated intensely since 2000, when a review on the net contribution of aquaculture to world fish supplies was published in Nature. This paper reviews the developments in global aquaculture from 1997 to 2017, incorporating all industry sub-sectors and highlighting the integration of aquaculture in the global food system. Inland aquaculture—especially in Asia—has contributed the most to global production volumes and...

Emerging COVID-19 impacts, responses, and lessons for building resilience in the seafood system

Love, D.C., E.H. Allison, F. Asche, B. Belton, R.S. Cottrell, H.E. Froehlich, J.A. Gephart, C.C. Hicks, D. Little, E.M. Nussbaumer, P. Pinto da Silva, F. Poulain, A. Rubio, J.S. Stoll, M. F. Tlusty, A.L. Thorne-Lyman, M. Troell, and W. Zhang. 2021. Emerging COVID-19 impacts, responses, and lessons for building resilience in the seafood system. Global Food Security 28:100494.

The COVID-19 pandemic and subsequent lockdowns are creating health and economic crises that threaten food and nutrition security. The seafood sector provides important sources of nutrition and employment, especially in low-income countries, and is highly globalized allowing shocks to propagate. We studied COVID-19-related disruptions, impacts, and responses to the seafood sector from January through May 2020, using a food sys-tem resilience ‘action cycle’ framework as...

Blind spots in visions of a ‘‘blue economy’’ could undermine the ocean’s contribution to eliminating hunger and malnutrition

Farmery, A. K., E. H. Allison, N. L. Andrew, M. Troell, M. Voyer, B. Campbell, H. Eriksson, M. Fabinyi, A. M. Song and D. Steenbergen. 2021. Blind spots in visions of a ‘‘blue economy’’ could undermine the ocean’s contribution to eliminating hunger and malnutrition. One Earth 4(1):28-38.

Increasing the production of food from the ocean is seen as a pathway toward more sustainable and healthier human diets. Yet this potential is being overshadowed by competing uses of ocean resources in an accelerating ‘‘blue economy.’’ The current emphasis on production growth, rather than equitable distribution of benefits, has created three unexamined or flawed assumptions that growth in the blue economy will lead to...

More than fish: Policy coherence and benefit sharing as necessary conditions for equitable aquaculture development

Brugere, C., M. Troell and H. Eriksson. 2021. More than fish: Policy coherence and benefit sharing as necessary conditions for equitable aquaculture development. Marine Policy 123:104271.

Aquaculture development is part of the Blue Economy narrative and it may offer opportunities for improving the well-being of coastal people and the wider population. However, unlocking its full potential is unlikely to occur through sole focus on increasing production. Using a framework for identifying the “people-policy gap” in aquaculture as a starting point, we introduce benefit sharing as a necessary and complementary concept to...

Recirculating Aquaculture Is Possible without Major Energy Tradeoff: Life Cycle Assessment of Warmwater Fish Farming in Sweden

Bergman, K., P. J. G. Henriksson, S. Hornborg, M. Troell, L. Borthwick, M. Jonell, G. Philis, and F. Ziegler. 2020. Recirculating Aquaculture Is Possible without Major Energy Tradeoff: Life Cycle Assessment of Warmwater Fish Farming in Sweden. Environmental Science & Technology 54(24):16062–16070.

Seafood is seen as promising for more sustainable diets. The increasing production in land-based closed Recirculating Aquaculture Systems (RASs) has overcome many local environmental challenges with traditional open net-pen systems such as eutrophication. The energy needed to maintain suitable water quality, with associated emissions, has however been seen as challenging from a global perspective. This study uses Life Cycle Assessment (LCA) to investigate the environmental...

Reorientation of aquaculture production systems can reduce environmental impacts and improve nutrition security in Bangladesh

Shepon, A., J. A. Gephart, P. J. G. Henriksson, R. Jones, K. Murshed-e-Jahan, G. Eshel and C. D. Golden . 2020. Reorientation of aquaculture production systems can reduce environmental impacts and improve nutrition security in Bangladesh. Nature Food (1):640–647.

Aquatic foods are a critical source of human nutrition in many developing countries. As a result, declines in wild-caught fish landings threaten nutritionally vulnerable populations. Aquaculture presents an opportunity to meet local demand, but it also places pressure on natural resource inputs and causes a range of environmental impacts. Here, we examine whether current aquaculture systems in Bangladesh can be reoriented to address prevailing nutritional...

Evidence for action: a One Health learning platform on interventions to tackle antimicrobial resistance

Wernli, D., Jørgensen, P.S., Parmley, E.J., Troell, M., et.al. 2020. Evidence for action: a One Health learning platform on interventions to tackle antimicrobial resistance. Lancet Infectious Diseases DOI:https://doi.org/10.1016/S1473-3099(20)30392-3.

Improving evidence for action is crucial to tackle antimicrobial resistance. The number of interventions for antimicrobial resistance is increasing but current research has major limitations in terms of efforts, methods, scope, quality, and reporting. Moving the agenda forwards requires an improved understanding of the diversity of interventions, their feasibility and cost–benefit, the implementation factors that shape and underpin their effectiveness, and the ways in which...

China at a Crossroads: An Analysis of China’s Changing Seafood Production and Consumption

Crona, B., E. Wassénius, M. Troell, K. Barclay, T. Mallory, M. Fabinyi, W. Zhang, V. W.Y. Lam, L. Cao, P. J.G. Henriksson, H. Eriksson. 2020. China at a Crossroads: An Analysis of China's Changing Seafood Production and Consumption. One Earth 3(1):32-44.

China is a key player in global production, consumption, and trade of seafood. Given this dominance, Chinese choices regarding what seafood to eat, and how and where to source it, are increasingly important—for China, and for the rest of the world. This perspective explores this issue using a transdisciplinary approach and discusses plausible trajectories and implications for assumptions of future modeling efforts and global environmental...

Scenarios for global aquaculture and its role in human nutrition

Gephart, J., C. D. Golden, F. Asche, B. Belton, C. Brugere, H. E. Froehlich, J. P. Fry, B. S. Halpern, C. C. Hicks, R. C. Jones, D. H. Klinger, D. C. Little, D. J. McCauley, S. H. Thilsted, M. Troell, E. H. Allisom. 2020. Scenarios for global aquaculture and its role in human nutrition. Reviews in Fisheries Science & Aquaculture 29(1):122-138.

Global demand for freshwater and marine foods (i.e., seafood) is rising and an increasing proportion is farmed. Aquaculture encompasses a range of species and cultivation methods, resulting in diverse social, economic, nutritional, and environmental outcomes. As a result, how aquaculture develops will influence human wellbeing and environmental health outcomes. Recognition of this has spurred a push for nutrition-sensitive aquaculture, which aims to benefit public health...
