The city of Kalmar is situated right at the Baltic sea in south-eastern part of Sweden. The Municipality of Kalmar has 69 467 inhabitants (SCB, 2019) and is the regional capital of Kalmar County. Kalmar is also the home of parts of the Linnaeus University.
Kalmar is a place of historical significance, and one of the oldest continuously inhabited cities in all of Scandinavia. Kalmar’s 17th century historical city centre is surrounded by the Baltic sea from three directions. Malmfjärden Bay is situated just north of the city centre and this one square kilometre sized bay is almost fully enclosed by land.
Malmfjärden is a popular area for recreation, such as canoeing, kayaking and SUP. A walking path and a bike lane surround the bay and the rich bird life attracts birdwatchers as well as the occasional fisherman. The bay itself is surrounded by one of the main arterial roads into central Kalmar and sees heavy traffic daily. The area also boasts several football fields as well as a local high school in the immediate vicinity. Being located so close to the city centre, Malmfjärden truly is an indistinguishable part of Kalmar’s townscape.
Most of Malmfjärden bay is less than one meter deep, except for a two-meter-deep boat lane that crosses the bay. For many years, the bay has received stormwater run-off from the nearby urban area. In the western parts of the bay, next to the football stadium, new apartments are being constructed and expected to be ready in the year 2022. Before the construction began, the land masses were removed as the area had been used as a dump site and the land masses were contaminated with heavy metals and hydrocarbons. To prevent future contamination of the bay, a storm water solution will be built in Malmfjärden.
Even though Malmfjärden has been used as a dump site and has received its fair share of pollution, the bay has high natural values sporting a rich flora and fauna. If left untreated however, Malmfjärden is at risk of suffering effects of eutrophication. With the advent of a new residential area at Malmfjärden, the bay must be remedied to keep good vitals that provides a sustainable environment for future generations of Kalmar.
The goal of the LIFESURE project is to restore Malmfjärden in order to achieve good ecological status, for today and for tomorrow. One way to achieve this is via dredging, where eutrophicated top-layer sediments are removed and then treated in a nearby facility. Pollutant levels will decrease, and ecological status will increase – Malmfjärden bay will be a living, attractive and sustainable area for humans, animals, and plants.
The LIFE SURE project has as main objective to test and demonstrate an innovative dredging system.
The LIFE SURE project works with two concepts: circular economy and innovative dredging methods.
