Shepon, A., Makov, T., Hamilton, H.A., Müller, D.B., Gephart, J.A., Henriksson, P.J.G., Troell, M., Golden, C.D. 2021. Sustainable optimization of global aquatic omega-3 supply chain could substantially narrow the nutrient gap. Resources, Conservation and Recycling (181)

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 potential for nar...

Seafood in Food Security: A Call for Bridging the Terrestrial-Aquatic Divide. Frontiers in Sustainable Food Systems doi.org/10.3389/fsufs.2021.703152

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 res...

The Synergistic Impacts of Anthropogenic Stressors and COVID-19 on Aquaculture: A Current Global Perspective. Reviews in Fisheries Science & Aquaculture doi.org/10.1080/23308249.2021.1876633

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...

The aquaculture supply chain in the time of covid-19 pandemic: Vulnerability, resilience, solutions and priorities at the global scale. Environmental Science & Policy doi: 10.1016/j.envsci.2021.10.014.

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 t...

In this paper, we critically analyze how sustainability is considered in aquaculture policies and strategies using the Nordic countries as a case. The strong versus weak sustainability concepts are used to define and clarify what sustainability aspects are central to each state. To illustrate these concepts further, we draw on and modify four mainstream environmental discourses defined by John Dryzek and apply them to the s...

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 ...

Henriksson, P.JG., Cucurachi, S., Guinee, J.B., Heijungs, R., Troell, M. & Ziegler, F. 2021. A rapid review of meta-analyses and systematic reviews of environmental footprints of food commodities and diets. Global Food Security-Agriculture Policy Economics and Environment 28, 100508.

Systematic reviews, sometimes including meta-analyses, are often presented as an approach for identifying healthy and sustainable diets. Here we explore to which extent systematic review protocols have been adopted by studies comparing environmental impacts of foods based on Life Cycle Assessment (LCA) results, and to which extent they comply with the PRISMA protocol for transparent reporting. Out of 224 studies screened, seve...

Cottrell, R.S., Metian, M., Froehlich, H.E., Blanchard, J.L., Sand Jacobsen, N., McIntyre, P.B., Nash, K.L., Williams, D.R., Bouwman, L., Gephart, J.A., Kuempel, C.D., Moran, D.D., Troell, M. & Halpern, B.S. 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...

Brugere, C., Troell, M. & Eriksson, H. 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 conc...

Environmental performance of blue foods. Nature 597(7876), 360-365.

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