While many studies focus on the exploration of possible futures, there is also a need to develop so-called normative scenarios, which consider objectives for the management of ocean uses, and possible pathways for these objectives to be met in the future. This session will focus on the presentation and discussion of recent advances and key scientific challenges in the formal modelling of marine socioecological systems, and alternative management scenarios. Presentations are invited that focus on the methodological dimensions or on practical case studies in a range of settings. These settings may include ecosystem-based management and fisheries restoration strategies. They can also include integrated ecosystem assessments or biodiversity scenarios, such as those which are being developed under the work of IPBES.
