I am interested in the sustainable utilisation of marine resources, particularly of fish in areas beyond national jurisdictions. Fish is an important source of food, however most harvest species are considered to be overfished. To mitigate human impacts on the ecosystem, states come together and founded agreements which influence existing organisations such as Regional fisheries management organisations, the only institution which regulates fisheries in the high seas. The interplay of environmental agreements, for example the Sustainable Development Goals, and the fisheries organisations is important for sustainable utilisation of fish resources. The aim of my PhD is to identify the links and interactions among fisheries organisations and environmental agreements for better fisheries management.
