Farming the Ocean – Seaweeds as a Quick Fix for the Climate?

Troell, M., P.J.G. Henriksson,  A.H. Buschmann, T. Chopin and S. Quahe. 2022. Farming the Ocean – Seaweeds as a Quick Fix for the Climate?. Reviews in Fisheries Science & Aquaculture .

Finding ways to keep global warming under 1.5 degrees Celsius is urgent and will need a portfolio of solutions. Seaweeds are marine photosynthetic organisms that humans harvest either from the wild or farm, to be used in many applications and providing various ecosystem services. Large scale farming of seaweeds for absorbing carbon has lately been promoted as a climate “fix”. The major shortcomings of this...

The vital roles of blue foods in the global food system

Tigchelaar, M. et al. 2022. The vital roles of blue foods in the global food system. Global Food Security 33:100637.

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 often be produced in ways that are more environmentally sustainable than terrestrial animal-source foods. Capture fisheries constitute the largest wild-food...

Seafood in food security: A call for bridging the terrestri­al-aquatic divide

Stetkiewicz, S. et al. 2022. Seafood in food security: A call for bridging the terrestri­al-aquatic divide. Frontiers in Sustainable Food Systems 5:703152.

The contribution of seafood to global food security is being increasingly highlighted in policy. However, the extent to which such claims are supported in the current food security literature is unclear. This review assesses the extent to which seafood is represented in the recent food security literature, both individually and from a food systems perspective, in combination with terrestrially-based production systems. The results demonstrate that...

Sustainable optimization of global aquatic omega-3 supply chain could sub­stantially narrow the nutrient gap

Shepon, A., T. Makov, H.A. Hamilton, D.B. Müller, J.A. Gephart, P.J.G. Henriksson, M. Troell, and C.D. Golden. 2022. Sustainable optimization of global aquatic omega-3 supply chain could sub­stantially narrow the nutrient gap. Resources, Conservation and Recycling 181:106260.

Omega-3 EPA and DHA fatty acids are vital for human health, but current human nutritional requirements are greater than supply. This nutrient gap is poised to increase as demand increases and the abundance of aquatic foods and the amount of omega-3 they contain may dwindle due to climate change and overfishing. Identifying and mitigating loss and inefficiencies across the global aquatic supply chain has great...

Scientific mobilization of Keystone Actors for Biosphere Stewardship

Österblom, H., C. Folke, J. Rocha, J. Bebbington, R. Blasiak, J.-B. Jouffray, E.R. Selig, C. C. Wabnitz, F. Bengtsson, B. Crona, R. Gupta, P.J. Henriksson, K.A. Johansson, A. Merrie, S. Nakayama, G.O. Crespo, J. Rockström, L. Schultz, M. Sobkowiak, P.S. Jørgensen, J. Spijkers, M. Troell, P. Villarru­bia-Gómez, and J. Lubchenco. 2022. Scientific mobilization of Keystone Actors for Biosphere Stewardship. Scientific Reports 12(3802).

The biosphere crisis requires changes to existing business practices. We ask how corporations can become sustainability leaders, when constrained by multiple barriers to collaboration for biosphere stewardship. We describe how scientists motivated, inspired and engaged with ten of the world’s largest seafood companies, in a collaborative process aimed to enable science-based and systemic transformations (2015–2021). CEOs faced multiple industry crises in 2015 that incentivized novel...

The aquaculture supply chain in the time of covid-19 pandemic: Vulnerability, resilience, solutions and priorities at the global scale

Mangano et al. 2022. The aquaculture supply chain in the time of covid-19 pandemic: Vulnerability, resilience, solutions and priorities at the global scale. Environmental Science & Policy 127:98-110.

The COVID-19 global pandemic has had severe, unpredictable and synchronous impacts on all levels of perishable food supply chains (PFSC), across multiple sectors and spatial scales. Aquaculture plays a vital and rapidly expanding role in food security, in some cases overtaking wild caught fisheries in the production of high-quality animal protein in this PFSC. We performed a rapid global assessment to evaluate the effects of...

Factors influencing antimicrobial resistance in the Euro­pean food system and potential leverage points for intervention: A participatory, One Health study

Lambraki, I.A., M. Cousins, T. Graells, A. Léger, P. Henriksson, S. Harbarth, M. Troell, D. Wernli, P. Søgaard Jørgensen, A.P. Desbois, C.A. Carson, E.J. Parmley, and S.E. Majowicz. 2022. Factors influencing antimicrobial resistance in the Euro­pean food system and potential leverage points for intervention: A participatory, One Health study. PLOS ONE 17(2):e0263914.

Introduction: Antimicrobial resistance (AMR) is a global crisis that evolves from a complex system of factors. Understanding what factors interact is key to finding solutions. Our objective was to identify the factors influencing AMR in the European food system and places to intervene. Materials and methods: We conducted two workshops involving participants with diverse perspectives to identify the factors influencing AMR and leverage points (places) to...

Studying factors affecting success of antimicrobial resistance interven­tions through the lens of experience: A thematic analysis

Graells, T., I.A. Lambraki, M. Cousins, A. Léger, K. Lillepold, P. J. G. Henriksson, M. Troell, C.A. Car­son, E.J. Parmley, S.E. Majowicz, D. Wernli, and P.S. Jørgensen. 2022. Studying factors affecting success of antimicrobial resistance interven­tions through the lens of experience: A thematic analysis. Antibiotics 11(5):639.

Antimicrobial resistance (AMR) affects the environment, and animal and human health. Institutions worldwide have applied various measures, some of which have reduced antimicrobial use and AMR. However, little is known about factors influencing the success of AMR interventions. To address this gap, we engaged health professionals, designers, and implementers of AMR interventions in an exploratory study to learn about their experience and factors that challenged...

Economic incentives drive the conversion of agriculture to aquaculture in the Indian Sundar­bans: Livelihood and environmental implications of different aquaculture types

Giri, S., T.D. Daw, S. Hazra, M. Troell, S. Samanta, O. Basu, C.L. Marcinko, and A. Chanda. 2022. Economic incentives drive the conversion of agriculture to aquaculture in the Indian Sundar­bans: Livelihood and environmental implications of different aquaculture types. Ambio 18:1-15.

Expansion of aquaculture in the Sundarbans Biosphere Reserve (SBR) is irreversibly replacing agricultural land and the drivers of this change are disputed. Based on in-depth interviews with 67 aquaculture farmers, this paper characterizes major aquaculture types in the SBR, their impacts, and identifies drivers of conversion from agricultural land. Aquaculture types included traditional, improved-traditional, modified-extensive, and semi-intensive systems. Extensive capture of wild shrimp larvae is environmentally harmful but constitutes an important...
