A new edited volume studies contemporary piracy from an (IR) constructivist perspectives and focuses especially on international institutions. The book titled Maritime Piracy and the Construction of Global Governance is edited by Michael J. Struett, Mark T. Nance and Jon D. Carlson and is the outcome of a 2011 workshop sponsored by the International Studies Association. In the chapter I contributed (together with Jan Stockbruegger) we investigate in how far the community of counter-practices can be understood as an alliance or a security community. Drawing on Buzan and Waever’s macrosecuritization framework we ask how actors collaborate and whether they share securitizations.
