Tampere's NBS Demonstration Areas
Tampere’s main demonstration site for nature-based solutions is Vuores. Vuores is a new greenfield district surrounded by natural water bodies, which currently is in the construction phase. The first residents moved to Vuores in 2010 and there are currently 3000 inhabitants living in the district. Intensive construction is still ongoing and it is planned that Vuores will be completed by 2030, with residences for 13,000 people and 3000 to 5000 jobs.
Vuores consists of existing and developing residential blocks located around multifunctional parks. The Vuores stormwater management system is one of the largest in the Nordic countries and the northernmost in the world. The heart of the Vuores nature-based stormwater management system is the Central Park, where retention ponds, swales, wetlands, and streams retain and purify the water before leading them to Lake Koipijärvi. The nature-based water management system already starts from plots where, e.g. green roofs, rain gardens and rainwater harvesting, serve both for water management as well as for recreation. One of the initial NBS demonstration ideas of the city included further development of the Vuores nature-based stormwater management system. A biofilter was the first part of the UNaLab nature-based solutions demonstrations in Vuores and has been built in Park Virolainen to treat stormwaters from nearby residential blocks and streets.
Innovative, co-created nature-based solutions systems demonstrated in Vuores will be scaled up and further developed in the brownfield area Hiedanranta. Hiedanranta is a former industrial area slated for development into a dense city district for 25,000 inhabitants and more than 10,000 jobs. Currently, Hiedanranta is open for people to enjoy and organise cultural- and art events and other innovations.
The first UNaLab demonstration in Hiedanranta is a pilot-scale algae-based water treatment system where researchers from Tampere University of Technology study microalgae growth in Nordic conditions. A biofilter has also been installed in Hiedanranta to treat the contaminated water from the old pulp mill. Online water monitoring devices have been installed to monitor the performance of the biofilters in the urban living labs and the results can be accessed online. Tampere will also implement a green roof on one building in the city centre.
The city has also awarded three innovation vouchers for citizens to undertake small-scale NBS projects. Two of the vouchers will be used to develop garden areas near residential housing while the third voucher has funded the creation of a horse park.
