International agreements are necessary for exclusion of non-cooperative behavior. We parameterized an age-structured model for the North Sea herring fishery. The reference points of the current harvest control rule operationalize the precautionary approach. Applying the precautionary approach by...

Heavy positively autocorrelated natural fluctuations in a fisheries stock level are problematic for fisheries management, and collapses in the stock dynamics are difficult to avoid. In this paper, we compare three different harvesting strategies (proportional harvesting, threshold harvesting,...

We present instrumental software for negotiation and decision support for transboundary air pollution abatement. Using this system the decision-maker can interact with a multiple criteria optimization model consisting of regional sulphur abatement cost functions and of a submodel describing the...

In this paper, a three-country dynamic bio-economic simulation model is presented for the spring-spawning herring fishery. The international spring-spawning herring fishery, based on potentially one of the most valuable fish stocks in the world, is currently recovering from a severe depletion of...
