Den framtida havsnivåhöjningens inverkanpå bebyggelse och infrastruktur
En fallstudie av Värmdö kommun
The sea-level is rising due to climate change. This report inquires into the possibleconsequences of sea-level rise in Värmdö and its archipelago with particular focus on roadsand buildings. Four scenarios with a sea-level rise of 0.5, 1.5, 2.5 meter and a worst casescenario of 3.9 meter are analyzed using a geographic information system (GIS) calledarcMap. The report also examines how Värmdö is taking into account future sea-level rise intheir planning today. The report´s findings show that uplift and sea-level rise cancel eachother out in the scenario with a sea-level rise of 0.5 meter, but that a number of more or lessimportant roads and buildings will be affected by a rise of 1.5 meters. The effect will be largerin the two remaining scenarios and include urban areas. Värmdö´s efforts of taking sea-levelrise in to consideration are flawed and they should more seriously consider future sea-levelrise as a threat.
