The 'seafood gap' in the food-water nexus literature—issues surrounding freshwater use in seafood production chains

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...

Environmental change and social conflict: the northeast Atlantic mackerel dispute

Spijkers, J., Boonstra, W.

2017 - Journal / article

A recurrent critique of the proposition of a causal relation between environmental change and social conflict is that it fails to account for the complexities and dynamics of processes of social-ecological change. In this article, we open the black box of contextual factors that influence the causal pathway from environmental change to social conflict. Firstly, we argue for the consideration of three social factors that influe...

Tinkering with a tanker—slow evolution of a Swedish ecosystem approach

österblom, H., Hentati-Sundberg,J., Nevonen, N., Veem, K.

2017 - Journal / article

The ecosystem approach is a salient policy paradigm originating from a scientific understanding of the reality of complex ecosystem dynamics. In this article, we investigate how Swedish national marine policies and practice between 2002 and 2015 have changed towards an ecosystem approach. Government documents, the scientific literature, institutional changes, changes in legislation, pilot projects, and changes in science and p...

The shape of success in a turbulent world: wave exposure filtering of coral reef herbivory

Bejarano, S., Jouffray, J.-B., Chollett, I., Allen, R., Roff, G., Marshell, A., Steneck, R., Ferse, S. C. A. and Mumby, P. J.

2017 - Journal / article

While environmental filters are well-known factors influencing community assembly, the extent to which these modify species functions, and entire ecosystem processes, is poorly understood. Focusing on a high-diversity system, we ask whether environmental filtering has ecosystem-wide effects beyond community assembly. We characterise a coral reef herbivorous fish community for swimming performance based on ten functional trai...
