Climate change & biodiversity

Risks and Opportunities for Locale Stakeholders of the North Sea 

Anthropogenic activities, like air and water pollution, fisheries, tourism and exploitation of resources (oil, gas, sand etc.) have induced changes in marine ecosystems of expanding dimensions. One apparent global effect induced in particular by climate change is the shift in species range in marine flora and fauna influencing local biodiversity, population structures, food webs and the coexistence of many ecological and economical relevant species.

Some marine ecosystems are less affected, while other marine regions are suffering vastly from those changes. Species native to the North Sea (Blue mussel and cod) are migrating to colder and slower warming regions in the higher latitudes, whereas those species are exhibited to increasing ecological pressure through increasing sea temperatures and competition by Lusitanian species (Mediterranean mussel and European sea bass) immigration from lower latitudes at the southern border of their distribution range. 

Simultaneously our society exploits the North Sea to a growing extent and profits especially in fisheries and tourism industry from the ecosystems services provided by high marine biodiversity.

In two workshops with stakeholders from fishery, aquaculture, fish processing industry, regulators, NGOs and research, we discussed the impacts of climate change on the environment, politics and society. Furthermore we discussed future measures for the adaptation to these changes and about science communication. 

One result is that in the future extreme weather events, such as the increasing frequency and intensity of storms and storm surges, will greatly impacts fishery, aquaculture and the coastal population. In order to adapt to the changing biodiversity, catch quota for the fishery need to be quickly adjusted to the availability of relevant species. Furthermore scientists see the ecosystems’ functional diversity threatened. In future the communication between research and society needs to be promoted to increase the awareness for the changes. At the same time social and ecological dimension need to be integrated in research.

Based on these results we developed the brochure “People and the North Sea under changing climate”. We want to inform interested people, visitors and residents of the North sea coast, fishermen and many more about climate change and its impacts on the North Sea.
