SEA meets LAND THREE YEARS IN KATTEGAT AND SKAGERRAK Welcome to KATTEGAT SKAGERRAK JUST THREE YEARS AGO... Imagine a world where • the map ends at the national border • knowledge is tucked away in boxes • cooperation is held back by fences A world in which climate change may soon lead to higher sea level and imbalance in the ecosystem. Where there are no common guidelines for the challenges we all face. Welcome to Kattegat Skagerrak. KATTEGAT SKAGERRAK The project Hav möter Land [Sea meets Land] has helped to change this picture. Feel free to share our findings and add your piece of the jigsaw to the big picture, for the sea and for the people. 4 THE SEA IS MINE AND YOURS – OUR JOINT RESPONSIBILITY attegat and Skagerrak – our part of the Atlantic.

The surface temperature may change in the Kattegat–Skagerrak region in a future climate. The map reveals the projected temperature change between two thirty- year periods; 1970--1999 and 2070--2099. This image would change if other climate scenarios or models were used, but the general result is still that the water temperature increases. MORE CERTAIN CHANGES: MORE UNCERTAIN CHANGES: • increased air and sea temperatures • wind speed • raised sea level • storm frequency • reduced solubility of oxygen • run-off • reduced ice cover • salt content 7 HARMONISATION The goal is healthy coastal environments but also provided knowledge about their strengths Sea meets Land has investigated the methods used and weaknesses.

M/S Latrina ran a similar campaign along the coast of Bohuslän, Sweden, in 2011. The campaigns highlighted problems and solutions. This clarified the challenges and shortcomings experienced by boaters along the coast. 337 boat owners participated in a questionnaire and a number of boats had their septic tanks emptied. The campaigns led to a lot of media coverage of the issues and positive feedback in both countries. Two successful summers.
