From the 23rd to the 24th November I attended the Galle Dialogue 2015, held in Galle, Sri Lanka. The Galle Dialogue is a major international multilateral meeting of navies in the Indian Ocean. Organised by the Sri Lankan navy, the dialogue attracted this year 300 participants from over 37 nations. The sixth installment of the dialogue, focussed on the theme “Secure seas through greater maritime cooperation”. The conference was opened by the prime minister of Sri Lanka, and included, among others, presentations by India’s chief of naval staff, Nigeria’s chief of naval staff, the deputy chief of staff from the Pakistan Navy, the State Minister of Defense of Sri Lanka, as well as representatives of UNHCR, IOM, and UNODC. The first day focussed on the contributions of different navies to maritime security in the Indian Ocean, while on the second day the issue of migration and international corporation to tackle ocean borne crime were discussed. As the only academic presenting at the conference, I discussed in my lecture the relationship between maritime security and the blue economy, and how more cooperative ocean governance structures might be set up. I drew on the results of the lessons learned project of the Contact Group on Piracy off the Coast of Somalia as well as my ongoing ESRC funded project on maritime security governance.
