Seven major types of sea space use (Nature Protection Measures, Fisheries Exploitation, Geological Exploitation, Recreation, Large Infrastructures, Navigation, Military uses) in the Polish Marine Areas are presented in terms of how much space is used (km2) for each use and the degree of overlap among the different uses. The greatest degree of conflict is noted with regard to Nature Protection (which overlaps with 60% of the areas used for Recreation and Geological Exploitation), and Fisheries Exploitation (which overlaps with 60% of the areas used for Nature Protection, Recreation, Infrastructure and Navigation). On the other hand, Fisheries Exploitation areas are the least disturbed by other users, and its major competitor is Nature Protection, which claims 20% of the areas used by fisheries. A GIS-based map that illustrates the degree of conflict is included, and the authors suggest participatory management as the proper way to minimize conflicts over sea space use and to promote the effective protection of natural resources.

This paper summarises current knowledge of goods and services in the Polish Exclusive Economic Zone of the Baltic Sea ecosystem. It reviews specific properties of the Baltic that could be used for economic valuation. Goods and services range from the familiar resources of fish and minerals, which were valued with the Productivity Method, to less obvious services provided by the ecosystem such as biofiltration in coastal sands, valued with either the Replacement Cost or Damage Cost Avoided methods. Disservices to the marine ecosystem are also considered, e.g. erosion and coastal flooding, including the costs of planned mitigating measures. This paper emphasises the importance of using valuation methods to help make better-educated decisions for the sustainability of the Baltic Sea.
