Klimatförändringars påverkan på kulturmiljöer i Uppsala stad ur ett geovetenskapligt perspektiv


Cultural heritages are environments created by humans that are considered to have a conservation value for the posterity. They can be seen as one of society's non renewable resources. It is important to have knowledge of how cultural heritages are affected by future climate changes.The water flow in Uppsala is estimated to increase during winter and decrease during spring and summer. Precipitation will gradually increase as well as the intense short period precipitation. The average temperature is estimated to increase as well. Despite the increased precipitation the soil moisture is predicted to decrease, as a result of the rising temperatures with an increased evaporation rate as a consequence.This study is carried out for the county administrative board in Uppsala county, in the field of climate change adaptation on the unit for emergency preparedness and civil contingency.The study focuses on three areas in Uppsala, city centre, Ha?gadalen and Vallsga?rde. Focus in the study is on the earth scientific consequences related to flooding as well as changes in precipitation. Maps has been produced in ArcGIS where floodings, soil types and cultural heritages are presented (appendix 1-3). 17 cultural heritages within the three areas has been established to be affected from floodings from Fyrisa?n where most of them are situated in the city centre of Uppsala. The changes in precipitation are the same throughout all studied areas, to what degree it will impact the cultural heritages depends on the characteristics of them. The ground is estimated not to be strongly affected by the increased amounts of water. But smaller settlings and land slides in clay rich soils can occur. The conservation of cultural heritages in the studied areas will not be widely negatively affected, except for some single objects, by the studied parameters.
