Introduction to BaltCICA and case studie in Kalundborg ”Part-financed by the European Union (European Regional Development Fund and European Neighbourhood and Partnership Instrument) Climate Change: Costs, Impacts and Adaptation in the Baltic Sea Region Jan Krause Pedersen

Precursory projects and results: BSR Interreg IIIB Project SEAREG “Sea Level Change Affecting Spatial Development in the Baltic Sea Region” Decision Support Frame BSR Interreg IIIB Project ASTRA “Developing Policies & Adaptation Strategies to Climate Change in the Baltic Sea Region”

The BaltCICA project … is designed to focus on the most imminent problems that climate change is likely to cause in the Baltic Sea Region. The concentration of large parts of the population and many larger cities in coastal areas make it especially sensitive to climate change. Climate adaptation calls for cooperation and integrated approaches in the Baltic Sea Region Picture: Veli Suominen

The BaltCICA Project aims Assessment of climate change impacts on the living environment and territorial development. Testing and implementation of concrete adaptation measures in close cooperation between regions or municipalities. Assessment of the costs of rising sea levels and increased flood risks on a pan-Baltic level. Development of a process management concept on climate change adaptation and mitigation.

Partners Partners from 8 different countries Regional and local administration, municipalities, nature reserves, research institutes of different disciplines and universities Geological Survey of Finland (GTK, lead partner) Helsinki University of Technology /Centre for Urban and Regional STUDIES (TKK/YTK) Hanko Water and Wastewater Works Union of the Baltic Cities – Commission on Environment (UBC) Helsinki Metropolitan Area Council (YTV) City of Helsinki City of Tampere Geological Survey of Estonia (EGK) University of Latvia North Vidzeme Biosphere Reserve Municipality of Klaipeda Municipality of the Klaipeda district Environmental Centre for Administration and Technology, Lithuania (ECAT) Vilnius University Lithuanian Geological Survey under the Ministry of Environment Kalundborg Municipality Danish Board of Technology (DBT) Geological Survey of Denmark and Greenland (GEUS) Nordic Centre for Spatial Development (Nordregio) Norwegian Institute for Urban and Region Research (NIBR) Leibniz Institute for Baltic Sea Research Warnemünde (IOW) HafenCity University/Institute for Urban-, Regional- and Environmental Planning (HCU) EUCC – The Coastal Union Germany Potsdam Institute for Climate Impact Research (PIK)

Models and scenario workshop GEUS: Modeling/simulation, IPCC scenarios A2, B2 (35-80 cm sea level rise, 12-16% more precipitation), groundwater/surfacewater interactions. Leading to: Local scenarios(do nothing scenario, buildings/infrastructural protection scenario, natur restoration scenarion, watermanagement and water as a ressource scenario. The Danish Border of Technology (DBT): Description of local scenarios, presentations, two local workshops with stakeholder and one citizen summit, identifing solutions, suggest action plans, method manual. The municipality of Kalundborg: Data supply, presentations, costs, interaction between stakeholders and public spatial planners as well as politicians, local political implementation. A small project conference event in Kalundborg with up to 100 participants.

Needs and results (the municipality) Models & tools easy to handle for the authorities/practical usable Socio-economic benefits and costs of natur/water/climate management (possibilities/limitations) Use of digital elevation models(GIS) Interest priorities Defining which data is needed for modeling Paradigmes/guidelines for impact assessment/decision processes Good ways to presentation of complex spatial planning
