Consequently, in order to aid policy formulation and decision-making the interactions and system dynamics in the continuum river catchment to the coastal zone need to be identified and studied. This paper focuses on the natural and human systems at catchment area level, and especially on the interactions and feedback mechanism between them. The framework and two case studies (Baltic Sea and Black Sea) are presented here, as well as suggestions for follow up. Sweden). For several reasons the text slowly took its shape and when the time for submittance came the contact with some in the group had been lost and was not to be restored as they had left the Academia. The manuscript became shelved for a long time until the three remaining authors decided to try to publish it by our own as we thought the text still had some qualities. This is now done as a report in a series from the Dept. of Water and Environmental Studies, Linköping University. We like to acknowledge the both the original working group and, especially, those active in this report, Drs.
