Mapping of cultural ecosystem services (CES) in marine and coastal areas is still recognised as a conceptually and technically challenging task, due to the difficulties in establishing a link between the biophysical features of the coastal ecosystem and the supply of services such as recreation and tourism, bird watching and enjoyment of other assets of nature. This was also one of the major challenges in ecosystem service mapping for the Maritime Spatial Plan for Internal Waters, Territorial Waters and Economic Exclusive Zone of the Republic of Latvia. Suitability of the coastal areas for marine tourism and leisure activities was chosen as an indicator to map the CES – physical and experiential interactions. The method involved the compilation of field data from a survey of visitors at the beach and on coastal infrastructure, serving as the input for the multi-criteria assessment of CES. Four criteria were applied to assess the suitability of the coastal areas for marine tourism and leisure activities: i) accessibility; ii) proximity to densely populated areas; iii) suitability of the area for a particular (niche) tourism or leisure activity; and iv) recreational use. The selected criteria provide an overall assessment framework, which integrates the ecosystem service potential, benefiting areas, flow and demand aspects. The CES mapping and assessment results were applied to the maritime spatial planning for proposing areas of priority for tourism development, as well as assessing the impacts of the proposed solutions for other uses of the sea. The Latvian approach for mapping of the cultural services in coastal areas was selected as the ESMERALDA case study and examined at the stakeholder workshop in Prague, September 2016.
