Tampere is the third largest city in Finland and the largest inland centre in the Nordic countries. Tampere is home to 225 150 inhabitants, and close to half a million people live in the Tampere Region, which comprises Tampere and its neighbouring municipalities. Tampere is one of the three most rapidly developing regions in Finland. It is a centre for leading-edge technology, research, education, culture, sports and business.
It is estimated that waterfall in Finland will increase by 25% in the coming years due to climate change. A critical issue for Tampere is therefore flooding and storm water management. As both demonstration areas in Tampere are under construction to become dense urban areas, the rapid population growth will pose a significant challenge. Other challenges that the city is facing include air and water pollution and reduced biodiversity.
Tampere’s main NBS demonstration site is Vuores. Vuores is a new greenfield district combining a proximity to nature, high-quality architecture, an ecological attitude, technological solutions, as well as small-town-like services. 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 heart of the Vuores nature-based storm water 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 starts already from plots, where e.g. green roofs, rain gardens, and rainwater harvesting serve both as water management as well as recreation.
A biofilter is the first part of the UNaLab demonstrations in Vuores, and is built in Park Virolainen to treat storm waters from nearby residential blocks and streets. The biofilter is capable to decrease the nutrient and microbiological load in the water.
Innovative, co-created NBS systems demonstrated in Vuores will be scaled up and further developed in the brownfield area Hiedanranta, which is also situated in Tampere. 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 Tampere and Hiedanranta is a greenhouse where researchers from Tampere University of Technology study microalgae growth in Nordic conditions.
