Ekosystemtjänster vid dagvattenhantering : En jämförelse av öppna dagvattenlösningar i urban miljö

Stormwater is a valuable resource but with climate change and changed precipitation it may cause problems in urban environments. With increasing urbanisation more land becomes exploited which can not naturally manage stormwater and solve the problems. The purpose with this study is to demonstrate the importance of green infrastructure to manage stormwater. The stormwater systems this study includes are different forms of green infrastructure; green areas, swales, ponds and wetlands. They manage stormwater, have different pros and cons and are various good at meeting the selected ecosystem services; balancing stormwater peaks, sewage treatment and groundwater recharge. Wetlands stand out as the best at meeting the ecosystem services balancing stormwater peaks and sewage treatment. Green areas are best with groundwater recharge. These areas can naturally manage stormwater and that is a strong reason to preserve and/or restore them during exploitation
