Patrik J. G. Henriksson, P., J.G., Rico, A., Troell, M. Klinger, D.H et al. 2017. Unpacking factors influencing antimicrobial use in global aquaculture and their implication for management: a review from a systems perspective. Sustain Sci., DOI 10.1007/s11625-017-0511-8
Global seafood provides almost 20% of all animal protein in diets, and aquaculture is, despite weakening trends, the fastest growing food sector worldwide. Recent increases in production have largely been achieved through intensification of existing farming systems, resulting in higher risks of disease outbreaks. This has led to increased use of antimicrobials (AMs) and consequent antimicrobial resistance (AMR) in many farming...
Gordon, L., Bignet, V., Crona, B. et.al. 2017. Rewiring food systems to enhance human health and biosphere stewardship. Environ. Res. Lett. 12 100201
Food lies at the heart of both health and sustainability challenges. We use a social-ecological framework to illustrate how major changes to the volume, nutrition and safety of food systems between 1961 and today impact health and sustainability. These changes have almost halved undernutrition while doubling the proportion who are overweight. They have also resulted in reduced resilience of the biosphere, pushing four out of s...

Henriksson, P.J.G., M. Dickson, A.N. Allah AN, D. Al-Kenawy, M. Phillips. 2017. Benchmarking the environmental performance of best management practice and genetic improvements in Egyptian aquaculture using life cycle assessment. Aquaculture doi:10.1016/j.aquaculture. 2016.09.051.
Egyptian aquaculture is gaining importance as an affordable and nutritious source of animal protein among Egyptians. Nile tilapia dominates production (77% of total production), followed by carps (17%) and mullets (11%). Egyptian tilapia farmers are, however, facing challenges with regards to financial viability and poor water quality. Fish farms are also contributing towards water pollution and other environmental impacts. In...
Henriksson, P. J.G., Trana, N., Mohana, C.,V., et. al. 2017. Indonesian aquaculture futures – Evaluating environmental and socioeconomic potentials and limitations. Journal of Cleaner ProductionVolume 162, 20 September 2017, Pages 1482–1490 DOI: 10.1016/j.jclepro.2017.06.133
Indonesia is the world's second largest seafood producer, but capture fisheries landings have stagnated over the last decade. In response, the Indonesian government has set ambitious targets for expanding the aquaculture sector up to 2030. The present research therefore quantifies environmental impacts using life cycle assessments (LCAs), and some socioeconomic indicators, for six alternative scenarios projecting the growth of...
Gephart, J. A., Troell, M., Henriksson, P.J.G., Beveridg, M.C.M, Verdegem, M., Metian, M., Mateos, L.D. Deutsch. L. 2017. The’seafood gap’ in the food-water nexus literature—issues surrounding freshwater use in seafoodproduction chains, Advances in Water Resources (2017), doi: 10.1016/j.advwatres.2017.03.025
Freshwater use for food production is projected to increase substantially in the coming decades with population growth, changing demographics, and shifting diets. Ensuring joint food-water security has prompted efforts to quantify freshwater use for different food products and production methods. However, few analyses quantify freshwater use for seafood production, and those that do use inconsistent water accounting. This inh...

Heijungs, R., P.J.G. Henriksson, J.B. Guinée. 2016. Measures of difference and significance in the era of computer simulations, meta-analysis, and big data. Entropy 18(10): 361.
In traditional research, repeated measurements lead to a sample of results, and inferential statistics can be used to not only estimate parameters, but also to test statistical hypotheses concerning these parameters. In many cases, the standard error of the estimates decreases (asymptotically) with the square root of the sample size, which provides a stimulus to probe large samples. In simulation models, the situation is entir...
Nhu, T.T., T. Schaubroeck, P.J.G. Henriksson, R. Bosma, P. Sorgeloos, J. Dewulf. 2016. Environmental impact of non-certified versus certified (ASC) intensive Pangasius aquaculture in Vietnam, a comparison based on a statistically supported LCA. Environmental Pollution 219: 156 – 165
Pangasius production in Vietnam is widely known as a success story in aquaculture, the fastest growing global food system because of its tremendous expansion by volume, value and the number of international markets to which Pangasius has been exported in recent years. While certification schemes are becoming significant features of international fish trade and marketing, an increasing number of Pangasius producers have followe...
Troell, M., Ziegler, F., Henriksson, P. 2016. Is fish a fish - adding fish to the global food sustainability transformation. Science 16 Sep 2016: Vol. 353, Issue 6305, pp. 1202-1204 DOI: 10.1126/science.aah4765
The Perspective on food sustainability (T. Garnett, 16 September, 353/6305) gives valuable insights related to links between dietary choices, environmental impacts and health. Substituting meat with fish could, as stated, only result in a transfer of impacts. If, however, fish is caught sustainably, respecting biological limits and using smart fishing methods, capture fisheries can produce low-impact food without requiring lan...

Henriksson, P.J.G., M. Troell, A. Rico. 2015. Antimicrobial use in aquaculture: Some complementing facts. Proceedings of the National Academy of Sciences USA 112: E3317
In their article “Global trends in antimicrobial use in food animals” (1), Van Boeckel et al. provide important insights into antimicrobial use in terrestrial animal production. Although aquaculture was deliberately excluded from their study, some extreme facts on antimicrobial use in aquaculture were mentioned. Here we briefly complement their study with more up-to-date information about the present use and trends of antimicr...
