IntroductionThe ocean's enormity and depth are illustrated by the limited ability of humankind to comprehend it. The current science and policy seascape remains largely fragmented, and as a result the integrity of marine life and the well-being of those (human and nonhuman) dependent on a healthy ocean is being negatively impacted. Fragmented governance is an indirect driver of ocean biodiversity loss due to its inability to provide synergistic solutions to address simultaneously multiple direct drivers for such loss (overfishing, land-based and marine pollution, and climate change). This governance problem is well known (Kelly et al., 2019;Watson-Wright and Valdés, 2018), and to some extent it is being addressed in ongoing international negotiations on an international instrument on marine biodiversity of areas beyond national jurisdiction (A/RES/72/249, 2017). This chapter will shed new light on these well-known problems by applying the lens of "transformative governance," understood as "formal and informal (public and private) rules, rule-making systems and actor-networks at all levels of human society (from local to global) that enable transformative change . . . towards biodiversity conservation and sustainable development more broadly," with a view to "respond[ing] to, manag[ing], and trigger[ing] regime shifts in coupled socio-ecological systems at multiple scales" (Visseren-Hamakers et al., 2021: 21; see also Chaffin et al., 2016 and Chapter 1 of this volume). We share the editors' views that there is a need to shift away "from the technocratic and regulatory fix of environmental problems to more fundamental and transformative changes in social-political processes and economic relations" (Otsuki (2015: 1; see also Chapter 1 of this volume). This can also help us to better understand how ocean biodiversity can contribute to "other environmental and social justice issues" 1 that are interwoven with the ocean in less visible ways than terrestrial biodiversity, such as poverty (Singh et al., 2018) and resource-grabbing (Virdin et al., 2021). 2 All the authors are part of the One Ocean Hub, a collaborative research for sustainable development project funded by UK Research and Innovation (UKRI) through the Global Challenges Research Fund (GCRF) (Grant Ref: NE/S008950/1). GCRF is a key component in delivering the UK AID strategy and puts UK-led research at the heart of efforts to tackle the United Nations Sustainable Development Goals.
