Cao, L., R. Naylor, P. Henriksson, D. Leadbitter, M. Metian, M. Troell, W. Zhang. 2015. China’s aquaculture and the world’s wild fisheries. Science 347: 133–135
China is the world's largest producer, consumer, processor, and exporter of finfish and shellfish (defined here as "fish"), and its fish imports are steadily rising. China produces more than one-third of the global fish supply, largely from its ever-expanding aquaculture sector, as most of its domestic fisheries are overexploited. Aquaculture accounts for ∼72% of its reported domestic fish production, and China alone contribut...

Metian, M., S. Pouil, A. Boustany, M. Troell. 2014. Farming of bluefin tuna: Reconsidering global estimates and sustainability concerns. Reviews in Fisheries Science & Aquaculture 22(3): 184-192.
Increased global demand for bluefin tuna has triggered unsustainable fishing and many wild stocks have seen dramatic declines. Improved fisheries governance is now slowly stabilizing many stocks and recently bluefin aquaculture has emerged as an economic alternative route for supplying the market. Most of captured bluefin tuna directly enters the global seafood market, but an increasing part of catches are destined to aquacu...

Scheffer, B.H. Walker, T. Xepapadeas, A.J. de Zeeuw 2014. Does Aquaculture Add Resilience to the Global Food System?. Proceedings of the National Academy of Sciences, epub, DOI:10.1073/pnas.1404067111
Aquaculture is the fastest growing food sector and continues to expand alongside terrestrial crop and livestock production. Using portfolio theory as a conceptual framework, we explore how current interconnections between the aquaculture, crop, livestock, and fisheries sectors act as an impediment to, or an opportunity for, enhanced resilience in the global food system given increased resource scarcity and climate change. A...

Production ecosystems typically have a high dependence on supporting and regulating ecosystem services and while they have thus far managed to sustain production, this has often been at the cost of externalities imposed on other systems and locations. One of the largest challenges facing humanity is to secure the production of food and fiber while avoiding long-term negative impacts on ecosystems and the range of services that...
Troell, M., M. Metian, M. Beveridge, M. Verdegem, L. Deutsch. 2014. Comment on 'Water footprint of marine protein consumption - aquaculture's link to agriculture'. Environmental Research Letters 9:109001 (4pp)
In their article 'Freshwater savings from marine protein consumption' (2014 Environ. Res. Lett. 9 014005), Gephart and her colleagues analyzed how consumption of marine animal protein rather than terrestrial animal protein leads to reduced freshwater allocation. They concluded that future water savings from increased marine fish consumption would be possible. We find the approach interesting and, if they only considered mari...

Jonell, M., Philips, M., Rönnbäck, P., Troell, M. 2013. Eco-certification of farmed seafood: will it make a difference? AMBIO Volume 42, Issue 6, pp 659-674
Eco-certification is widely considered a tool for reducing environmental impacts of aquaculture, but what are the likely environmental outcomes for the world’s fastest growing animal-food production sector? This article analyzes a number of eco-certification schemes based on species choice, anticipated share of the global seafood market, size of eligible producers, and targeted environmental impacts. The potential of eco-c...
Beveridge, M. C. M., Thilsted, S. H., Phillips, M. J., Metian, M., Troell, M. and Hall, S. J. (2013), Meeting the food and nutrition needs of the poor: the role of fish and the opportunities and challenges emerging from the rise of aquaculture. Journal of Fish Biology, 83: 1067–1084. doi: 10.1111/jfb.12187
People who are food and nutrition insecure largely reside in Asia and Sub-Saharan Africa and for many, fish represents a rich source of protein, micronutrients and essential fatty acids. The contribution of fish to household food and nutrition security depends upon availability, access and cultural and personal preferences. Access is largely determined by location, seasonality and price but at the individual level it also de...

Social-ecological systems as complex adaptive systems: modeling and policy implications. Environment and Development Economics, 18(2)
Systems linking people and nature, known as social-ecological systems, are increasingly understood as complex adaptive systems. Essential features of these complex adaptive systems – such as nonlinear feedbacks, strategic interactions, individual and spatial heterogeneity, and varying time scales – pose substantial challenges for modeling. However, ignoring these characteristics can distort our picture of how these systems wor...
Österblom, H., Merrie, A., Metian, M., Boonstra, W.J., Blenckner, T., Watson, J.R., Rykaczewski, R.R., Ota, Y., Sarmiento, J.L., Christensen, V., Schlüter, M., Birnbaum, S., Gustafsson, B., Humborg, C., Mörth, C-M., Müller-Karulis, B., Tomczak, M.T., Troell, M., and Folke, C. BioScience , Vol. 63, No. 9 (September 2013), pp. 735-744
Human activities have substantial impacts on marine ecosystems, including rapid regime shifts with large consequences for human well-being. We highlight the use of model-based scenarios as a scientific tool for adaptive stewardship in the face of such consequences. The natural sciences have a long history of developing scenarios but rarely with an in-depth understanding of factors influencing human actions. Social scientists h...
