Making difficult and informed trade-offs among competing uses of marine resources is central to effective ecosystem-based management (EBM) and achieving the United Nations' Sustainable Development Goals. Trade-offs are equally central to ICES Vision of “meeting societal needs for impartial evidence on the state and sustainable use of our seas…" and ICES Mission of generating “advice for meeting conservation, management, and sustainability goals." More specifically the ecosystem approach to fisheries aims to provide advice to make management trade-offs. Similarly, the ICES Science Plan states that “understanding […] pressures and their impacts will provide evidence to advise on trade-offs between benefits and risks."
While the need for managers to make trade-off decisions is clear and well-recognized, how do they actually do this effectively across diverse environmental, economic, and social objectives and risks? Different disciplines and management systems have different approaches to how they measure and evaluate trade-offs across alternative uses of scarce ocean resources.
The session identifies methods and presents diverse case studies on providing effective trade-off evaluations in complex management and allocation situations.
We welcome any relevant talks, as the goal of the session is to present diverse approaches to this universal problem. Key questions that we hope to consider are:
ICES Science Plan recognizes that there are non-monetary cultural identities supported by fisheries in addition to more easily measured economic and environmental attributes. How should trade-offs be framed for decision makers to fairly recognize these values? The session strives to be an important step towards the more effective consideration of meeting diverse management objectives when making trade-offs.
