-2,32m: How to protect a city under water?

Sammanfattning

Kristianstad is a city of 41.000 inhabitants in southern Sweden. Once a fort on an island in the river of Helge Å, parts of the river and surrounding lakes were lowered or removed as the city expanded. This has caused parts of Kristianstad to have the lowest point in Sweden, -2,32 meters below ocean level. The surrounding river has an important role as it creates a wetland ecosystem called Vattenriket that surrounds the city. This area is recognised as a biosphere reserve of international importance. Water is currently held at bay with help of embankments, but the city experiences recurring floods during years of high water levels. The threat that the water poses is expected to increase by the end of the century due to rising sea levels. How can a city combat flooding through use of urban design in relation to local ecosystems in an era of rising water levels? This project is about how a city in an exposed position could deal with water, ecosystems services and sustainable development in a changing climate with care towards the surrounding wetland, to use it as a major tool in how to tackle the challenges ahead.
