Bergman, K., Henriksson, P.J., Hornborg, S., Troell, M., Borthwick, L., Jonell, M., Philis, G. and Ziegler, F., 2020. Recirculating Aquaculture Is Possible without Major Energy Tradeoff: Life Cycle Assessment of Warmwater Fish Farming in Sweden. Environmental science & technology.
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 A...

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 coevolution...

Tlusty, M.F., Tyedmers, P., Bailey, M., Ziegler, F. Henriksson, P.J.G., et.al. 2019. Reframing the sustainable seafood narrative. Global Environmental Change
The dominant sustainable seafood narrative is one where developed world markets catalyze practice improvements by fisheries and aquaculture producers that enhance ocean health. The narrow framing of seafood sustainability in terms of aquaculture or fisheries management and ocean health has contributed to the omission of these important food production systems from the discussion on global food system sustainability. This omiss...
Henriksson, P.J.G., Banks L.K., Suri S.K., Pratiwi T.Y., Fatan M.R. 2019. Indonesian aquaculture futures — identifying interventions for reducing environmental impacts. Environmental Research Letters
Indonesia is the world's second largest producer and third largest consumer of seafood. Fish is thus essential to the nation, both financially and nutritionally. Overfishing and the effects of climate change will, however, limit future capture fisheries landings, so any increases in future seafood production will need to come from aquaculture. Aquaculture's ecological effects are dependent upon the choice of species, managemen...

Aquaculture is receiving increased attention from a variety of stakeholders. This is largely due to its current role in the global food system of supplying more than half of the seafood consumed, and also because the industry continues to steadily expand (UN Food and Agriculture Organization 2018). A recent article in Environmental Research Letters, 'Feed conversion efficiency in aquaculture: do we measure it correctly?', by F...

The industrialized world has entered a new era of widespread automation, and although this may create long-term gains in economic productivity and wealth accumulation, many professions are expected to disappear during the ensuing shift, leading to potentially significant disruptions in labor markets and associated socioeconomic difficulties. Food production, like many other industrial sectors, has also undergone a century of m...
Hamann, M., Berry, K., Chaigneu, T., Curry, T. et. al. 2018. Inequality and the Biosphere. Annual Review of Environment and Resources Vol. 43:- (Volume publication date October 2018) https://doi.org/10.1146/annurev-environ-102017- 025949
Rising inequalities and accelerating global environmental change pose two of the most pressing challenges of the twenty-first century. To explore how these phenomena are linked, we apply a social-ecological systems perspective and review the literature to identify six different types of interactions (or “pathways”) between inequality and the biosphere. We find that most of the research so far has only considered one-directiona...
Järviö, N., P. Henriksson, J. Guinée. 2018. Including GHG emissions from mangrove forests LULUC in LCA: a case study on shrimp farming in the Mekong Delta, Vietnam. International Journal of Life Cycle Assessment doi:10.1007/s11367-017-1332-9.
Our results reinforce the urgency of conserving mangrove forests and the need to quantify uncertainties around LULUC emissions. It also questions mixed mangrove concurrent shrimp farming, where partial removal of mangrove forests is endorsed based upon the benefits of partial mangrove conservation and maintenance of certain ecosystem services. While we recognize that these activities limit the chances of complete removal, our ...
Cao, L., R. Naylor, P. Henriksson, D. Leadbitter, M. Troell, W. Zhang. 2017. Rebuttal to Han et al., Reviews in Aquaculture, 2016 doi: 10.13140/RG.2.2.27925.93928.
As authors of " China's aquaculture and the world's fisheries " (Cao et al., Science, 2015), we would like to dispute several claims presented in " A revisit to fishmeal usage and associated consequences in Chinese aquaculture " (Han et al., Reviews in Aquaculture, 2016), as the latter seriously misrepresents the intent and substance of our Science paper. In their review, Han and colleagues argue that although China's aquacult...

Heijungs, R., P.J.G. Henriksson, J.B. Guinee. 2017. Pre-calculated LCI systems with uncertainties cannot be used in comparative LCA. International Journal of Life Cycle Assessment 22(3): 461-461
A recent paper by Qin and Suh (2016) provides an interesting test of the assumption of lognormally distributed life cycle inventory (LCI) results. We appreciate the importance of this work, and acknowledge that finding out this result must have taken a long computation time. In that respect, we would like to comment on the remark in section 4 that “conducting uncertainty analysis from the unit process level is neither time-eff...
