A systematic quantitative review of coastal and marine cultural ecosystem services: Current status and future research

Abstract

Cultural ecosystem services (CES) are the non-material benefits obtained from ecosystems that contribute to human well-being. They are often under-represented in ecosystem services assessments due to difficulties identifying and valuing intangible attributes. This risks a lack of understanding and consideration of CES by decision-makers. A systematic review was done on coastal and marine CES to identify: geographic distribution of research; effective methods for assessing CES; specific habitats/ecosystems that supply CES; subcategories most frequently addressed; and knowledge gaps. Results revealed limited information exists about coastal and marine CES. There is a disparity in the global distribution of studies with little knowledge about CES in developing countries, as well as a disparity within developed countries; with most research undertaken in Europe and North America. There is a dearth of information on CES derived from specific coastal and marine habitats/ecosystems, reflecting a poor understanding of socio-ecological relationships and the different values people assign to these areas. There is a need to develop indicators with the capacity to measure and track changes in CES over time. Participatory approaches using qualitative methods were most effective in identifying CES; however, these lacked a deliberative element that would provide a comprehensive assessment of shared values in public areas. Overall, publications typically theorised about the usefulness of data on CES to inform and support decision makers, and more research is required on how qualitative data on CES can be represented for practical use by coastal and marine resource managers, and the value of these in the real world.
