The aim of MARISPLAN was to analyse how climate change impacts human activities and the marine environment, and how these changes should be taken into account in marine spatial planning.
It was shown that climate change affects nutrient loading both via its direct effect on freshwater runoff and via its effect on agricultural practices. The analysis also showed that, by adapting to the climate change at farm level, a significant reduction in the nutrient loading can be achieved. It was also shown that climate change decreases water salinity, and that the distribution areas of certain key species, such as bladderwrack and blue-mussel, will consequently be reduced. Also some non-indigenous species, will benefit from the expected changes.
The results can be used to determine how the society should adapt to climate change, and vice versa, how climate change should be taken into account in the spatial planning process, including spatial protection of the sea.
