Marine and Freshwater Systems

Denmark has a very long coastline, and coastal areas and freshwater systems are important recreational areas, as well as important spawning areas for fish and other animals and plants. Regulating processes, such as nutrient retention, take place in coastal areas as well as in freshwater systems and the marine and freshwater regulating services are therefore also important for the ecological status of the marine and freshwater ecosystems. . is Environmental regulation has had significant emphasis on achieving good ecological status of freshwater and marine systems. In our research we have contributed to research and policy advice on the economic benefits of improved ecological status, as well as to how these benefits can be achieved and protected. The Marine Strategy Framework Directive (MSFD) offers Member States to employ ecosystem services approaches in the assessment of the benefits of the use of the marine waters and the costs of degradation, and we advise the Danish Ministry of Environment and Food in the use of ecosystem services approaches, existing studies and use of these in the MSFD context. orcahes perspective and allows member staIn particular, research activities have aimed to understand the cultural services related to freshwater and marine systems, where recreation has been in focus. Provisioning and regulating services such as food provision and nutrient regulation by mussel farming in eutrophic fjords and coastal areas are also under study.  Eelgrass meadows

In ENVS we have developed approaches and models to link management strategies of agricultural systems to marine and freshwater quality. This has focused on the development of spatially explicit models to understand cost effectiveness of alternative strategies and the synergies and trade-offs between provision of water ecosystem services and terrestrial ecosystem services. Research activities have investigated the costs and benefits of investing in blue biomass production.
