This Open Access book “Ocean Governance (Beyond) Borders” is concerned with the persistence of bordering in ocean space, and the possibilities that might arise if we think beyond borders for modes of oceanic management, engaging the ocean’s fluid physicality and the mobile human and more-than-human life entangled with it. At a moment where ocean governance is a pressing topic amongst academics, policy makers, governments and non- governmental agencies alike, this book takes on one of the most overlooked but central devices underscoring many modes of oceanic management: the border. Uniquely combining contemporary border scholarship with cutting edge ocean governance research this book tackles themes ranging from biodiversity conservation and asylum regulations to shipping management measures, tourism, and the growing blue economy. This edited volume hence explores varied bordering practices, whilst also addressing the ‘common-senseness’ with which bordering is deployed at sea, questioning – and problematising – its function and efficacy. Throughout 12 carefully curated chapters, authors ask: What borders are present in the seas and oceans, where and why? In doing this the book offers readers a simple provocation: Do we need borders? And can we govern differently?
