In a new draft paper written for the edited volume “Concepts in Action/at Work: On the Meaning of Concepts in International Politics”, edited by Piki Ish-Shalom, I discuss the rise of the concept of “blue economy”. Blending an empirical reconstruction of different forms of using the concept as a tool for advancing political projects, I argue for basing concept analysis on practice theoretical foundations. The draft is available via my academia page at this link. As usually I am delighted for any comments and suggestions.
