The Baltic Sea Broad-scale MSP Principles, Regional Baltic MSP Roadmap 2013-2020, and Guidelines on transboundary consultations, public participation and co-operation provide a common regional framework supporting cross-border cooperation and coherent national MSP implementation in the BSR. Within this activity application of the 3 documents in the Baltic sea countries will be evaluated. Important here is to see how they work in practice, how successful the countries have been in implementing joint framework and to come up with suggestions on possible improvements in existing framework as well as set the scope for future agenda.
