Maritime piracy – hijackings, kidnapping, hostage taking and armed robbery at sea – presents an ongoing challenge for the international community. What was long perceived as a problem of the past is today recognised to be a major challenge for international security. To act against piracy has proven to be an intricate affair. The new attention to piracy and indeed the return of the problem on the agendas of global politics started with the significant increase of piracy incidents in Southeast Asia in the 1990s. Southeast Asia has since seen the creation of a regional cooperation framework that addresses piracy through information sharing, improved coordination and common strategy making. Although piracy incidents in the area still occur, a viable counterpiracy infrastructure has been put in place to address the menace, and arguably piracy is well contained in the area. Piracy in the Horn of Africa and the Western Indian Ocean region is a different story. The international community has been increasingly engaged in the area since 2007, when the UN Security Council began to approach the issue. International actors, including states and international organisations, have been quite innovative in organising the response: multilateral naval missions organised by the US, NATO and the EU have been dispatched to the area; over 30 states participate in naval counterpiracy activities; states, international organisations (including the UN, the International Maritime Organisation, Interpol and the UN Office of Drugs and Crime) and private actors (such as shipping associations) coordinate their activity in the working groups of a UN Contact Group; over 1000 pirates have been prosecuted or are awaiting trial; and a complex international counterpiracy programme mixes security and law enforcement with regional rule of law projects, maritime security sector reforms and development programmes. Yet success is still limited. According to Jack Lang, the UN special adviser on piracy, ‘the race between the pirates and the international community is progressively being won by the pirates’. 1 The authors of this special section discuss what makes it so difficult for the international community to cope with piracy. They discuss the intricacies of finding tailored strategies and the obstacles and complexities that actors face in addressing Somali piracy. The authors draw on research from the emerging inter-disciplinary field of piracy studies, which has attracted a growing number of researchers from different disciplines. 2 Piracy studies is an intellectual project that focuses on understanding the return of piracy, how piracy is organised in different parts of the world, how it is embedded in a larger historical context and as part of international dynamics, and how counterpiracy responses can be improved (Bueger, 2013). It explores the relationship between piracy and other threats, such as terrorism, and uses it as a paradigmatic example for understanding contemporary international problems. Through this lens, piracy studies facilitate a productive inter-disciplinary dialogue and bring perspectives into the conversation that have often been understood as competitors or even as incommensurable.
