- There is an urgent need for developing policy-relevant future scenarios of biodiversity and ecosystem services. This paper is a milestone toward this aim focusing on open ocean fisheries. We develop five contrasting Oceanic System Pathways (OSPs), based on the existing five archetypal worlds of Shared Socioeconomic Pathways (SSPs) developed for climate change research (e.g., Nakicenovic et al., 2014 and Riahi et al., 2016). First, we specify the boundaries of the oceanic social-ecological system under focus. Second, the two major driving forces of oceanic social-ecological systems are identified in each of three domains, viz., economy, management and governance. For each OSP (OSP1 sustainability first, OSP2 conventional trends, OSP3 dislocation, OSP4 global elite and inequality, OSP5 high tech and market), a storyline is outlined describing the evolution of the driving forces with the corresponding SSP. Finally, we compare the different pathways of oceanic social-ecological systems by projecting them in the two-dimensional spaces defined by the driving forces, in each of the economy, management and governance domains. We expect that the OSPs will serve as a common basis for future model based scenario studies in the context of the Intergovernmental Panel on Climate Change (IPCC) and the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES).

Forskningsöversikt (refereegranskat)abstract
- Oceanic ecosystems support livelihoods and supply food for hundreds of millions of people. But these ecosystems are deteriorating rapidly and many of the world's oceanic fisheries are in a precarious condition. In addition to well-known and pressing fishery management issues, economic globalization is connecting fisheries beyond the frontiers of the organizations responsible for their management and climate-associated changes are deeply modifying ecosystems, pushing them toward new states and no return situations. The status quo is not a sustainable option, and improved international governance is urgently needed to address this situation. Our proposition consists of an inclusive global science-policy process combining major improvements to the present governance systems, including new incentives for international cooperation and coordination, with an ambitious scientific program to help anticipate threats and opportunities and integrate complex information regarding long-term issues. It would constitute a major step toward sustainability.
