On the 30th of May I am giving a lecture as the keynote of the International Conference on Maritime Security hosted by the Lusiada Research Centre for International Policy and Security, Universidade Lusíada de Lisboa. In the lecture titled “Situating Maritime Security” I discuss how the maritime security is related to the broader policy debates on ocean governance as well as international security. Drawing on earlier work on the concept of maritime security and the lessons from piracy, I argue that in particular the global maritime domain awareness structures and international capacity building efforts require further scrutiny.
