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...

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...

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...

Interplay of trade and food system resilience: Gains on supply diversity over time at the cost of trade independency

Kummu, M.,P. Kinnunen, E. Lehikoinen, M. Porkka, C. Queiroz, E. Röös, M. Troell and C. Weil. 2020. Interplay of trade and food system resilience: Gains on supply diversity over time at the cost of trade independency. Global Food Security 24 (2020) 100360.

Rapidly increasing international food trade has drastically altered the global food system over the past decades. Using national scale indicators, we assess two of the resilience principles that directly reflect the effects of global trade on food systems – namely, maintaining diversity and redundancy, and managing connectivity. We perform our analysis for four nutritional components: dietary energy, proteins, fat, and quantity of vegetables & fruits...

Coevolutionary Governance of Antibiotic and Pesticide Resistance

Jørgensen, P. S., C. Folke, P. J. G. G. Henriksson, K. Malmros, M. Troell, A. Zorzet, and Living with Resistance project. 2020. Coevolutionary Governance of Antibiotic and Pesticide Resistance. Trends in Ecology and Evolution: 35(6):484-494.

Development of new biocides has dominated human responses to evolution of antibiotic and pesticide resistance. Increasing and uniform biocide use, the spread of resistance genes, and the lack of new classes of compounds indicate the importance of navigating toward more sustainable coevolutionary dynamics between human culture and species that evolve resistance. To inform this challenge, we introduce the concept of coevolutionary governance and propose three...

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...

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...

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...

Corridors of Clarity: Four Principles to Overcome Uncertainty Paralysis in the Anthropocene

Polasky S., A.-S. Crépin, R. Biggs, S. R. Carpenter, C. Folke, G. Peterson, M. Scheffer, S. Barrett, G. Daily, P. Ehrlich, R. B. Howarth, T. Hughes, S. A. Levin, J. F. Shogren, M. Troell, B. Walker, and A. Xepapadeas. 2020. Corridors of Clarity: Four Principles to Overcome Uncertainty Paralysis in the Anthropocene. BioScience biaa115.

Global environmental change challenges humanity because of its broad scale, long-lasting, and potentially irreversible consequences. Key to an effective response is to use an appropriate scientific lens to peer through the mist of uncertainty that threatens timely and appropriate decisions surrounding these complex issues. Identifying such corridors of clarity could help understanding critical phenomena or causal pathways sufficiently well to justify taking policy action. To...
