Improving confidence in complex ecosystem models: The sensitivity analysis of an Atlantis ecosystem model

The Risky Decrease of Fishing Reference Points Under Climate Change

“…Considering uncertainty attached to model results is the next step in this direction as it would increase transparence, credibility and therefore usefulness of ecosystem models for fisheries advice (Lehuta et al, 2016). Identifying which parameters are the most influential on model output allows prioritizing research toward reduction of model uncertainty (e.g., more accurate estimation of model parameters) and better understanding of model structure and error propagation (Bracis et al, 2020;Xing et al, 2020).…”

Exploring multiple stressor effects with Ecopath, Ecosim, and Ecospace: Research designs, modeling techniques, and future directions

“…In the future, big data consisting of model inputs and the corresponding model outputs could be fed into machine learning algorithms that can extract complicated non-linear relationships and interactions between variables describing stressors and variables describing ecosystem condition. Such data sets could also be used in global sensitivity analyses, allowing quantification of the direct and indirect contributions of model inputs describing stressors to changes of outputs describing ecosystem condition (Bracis et al, 2020;Saltelli et al, 2004). The generated data could simultaneously contribute rigorous uncertainty analyses, which are crucial for high-stakes applications in environmental policy and practice (Saltelli and Funtowicz, 2014;Steenbeek et al, 2021a).…”

Lost in Translation – Following the Ecosystem Approach from Malawi to the Barents Sea

“…Indeed, the EA was regarded by some as too complex to comprehend with "hard sciences" only. 90 Another aspect underscored during the 7 th UNICPOLOS meeting was the need to preserve the primacy of the 1982 UNCLOS, and full implementation of its provisions, 91 implying that an EA could not interfere with provisions in the "Law of the Sea". It was suggested that the Large Marine Ecosystem (LME) approach was equivalent to the EA and pointed out that it was already reflected or defined in various international instruments such as the 1982 UNCLOS, the "UN Fish Stocks Agreement", the CBD, the FAO Code of Conduct for Responsible Fisheries, the Reykjavik Declaration on Responsible Fisheries in the Marine Ecosystem and the Convention for the Conservation of Antarctic Marine Living Resources.…”
