1 The Scenario Barents Sea Study, a Case of Minimal Realistic Modelling to compare Management Strategies for Marine Ecosystems
Management of a marine ecosystem is regarded as a game played by the Government Agency against Nature. The quality of the management strategy is evaluated using models for the strategy taken by Nature. These models should be sufficiently realistic and also practical to implement and investigate on a...
