Maintenance and management of urban nature

In 2015, the municipality of Białystok restored the riverbed of the Biala river to its natural state. The project addresses the rapidly changing climate and atmospheric conditions which cause more frequent storms by improving the water management in the city. The city reconstructed the old riverbanks, built two ponds for retention, which serve as reservoirs and tanks to stop and distribute the excess water [1,2].

Tallinn implemented a community-based action plan for urban development in the Paljassaare conservation area, aimed at raising cattle on the Paljassaare peninsula, creating community-based beauty and vegetable gardens and restoring a wetland and lakeshores (ref. 3). The Paljassaare area several protected areas required active intervention in the form of care. The management of urban animals had the following objectives implemented: Paljassaare Wetland Complex Restoration; maintenance of a mosaic semi-natural habitat based on conservation values; updating protection regimes and organization; modern visitor arrangement based on protection values ​​and visitor intensiveness (ref. 2).

Extending from Kalasadam to the Noblessner quarter, the beta-promenade is a simple footpath along the seaside (from the fish market of the Fishing Harbor to the port town of Noblessner), created by removing fences, opening up gates and fortifying the shore. (ref 1) It is a project for public space creation in Tallinn Seaside by Linnalabor, where the seafront area is heightened in the public interest (Ref 2)
The beta promenade was made by filling an old, impassable landfill on a sometimes bumpy and fenced-in, but sea-view and spacious footpath, opening the old gate of the Patarei Fortress wall and marking the nearly two-kilometre shore route (ref. 1).

The NBS is located on a previously neglected basketball and other games fields with obsolete and long unused equipment. Owing to the citizens’ initiative, the municipality built a new sport and leisure site at the Jaroszowka housing estate in Białystok. The project has increased social integration between different generations and provided a comfortable, safe and surrounded by nature space for sports and recreation. The project involved the planting of greenery, building a multifunctional playground and a multisport field, and it was complemented by benches, toilets, CCTV, and lights [1,2,4].

In 2016, owing to the participatory budget of Białystok, the citizens received a long-awaited outdoor gym and playground in the vacant green area of the city. The initiative aimed to increase public access to the green recreational area in the city, and connect the Białka riverside with residential boroughs. The project involved greenery planting and re-arrangement of the greenery (including some deforestation), revitalization of a pond and water purification, connecting walking and bicycle paths. Lawns are available for family picnics and recreation [1,2].

The project aims to turn Honkasuo forest and meadow area into an urban village to house 2000 residents. These delightful nature elements have been preserved, for the most part, and the wave of sustainable development that is sweeping over the area has a definite environmental/ecological symbol as well (ref. 4). The constructions are aimed to be made out of wood and are meant to attract a diversity of people. Part of this project is the creation of a park, urban farming plots, natural design to attract butterflies, a playground and natural ponds to retain rainwater (ref. 2,3,4). Part of the development has been completed with residents start moving in 2016, although the landscaped embankment is expected to be completed in 2022

The lake, which is fed by brook Rio Archetti, is located in the highest section of the park, immediately down from the Villa Doria camping ground, in an area of the public park that is not very frequented. It used to be in great decline, because of many maintenance and environmental factors. This intervention brought it back to its original estate, recreating the original historical and natural value the area had, highly popular among local residents as a green place where to enjoy calm and silence in the center of the city.

Meadow orchards with fruit trees were an integral part of subsistence farming and form part of the cultural heritage of Wuppertal. To preserve and further develop these meadows as an important habitat for flora and fauna and promote their potential for sustainable consumption, 4 such meadows were sponsored, maintained and promoted by the city of Wuppertal in close collaboration with the working group for fruit meadows via events, communal harvesting activities and hands-on courses since 1999. Since 2015, these meadows have increasingly drawn the attention of "foodsharing" movements and during the nationwide research year "future town". (Ref. 1, 2, 6, 8). Enclosed between areas of intensive conventional agriculture and the federal motorway, the orchards as islands of biological diversity are important places of retreat and relaxation. (Ref. 5) Communal activities are also offered, such as the co-creation of “edible experience spaces”, joint harvesting and providing a base for additional social projects (Ref. 6).

The Royal Gardens, situated between Piazza San Marco and the Bacino di San Marco, came into being during the Napoleonic occupation of the city and used to be a space for recreational activities for locals for many years after the monarchy was over. During past decades, the gardens have progressively deteriorated. Their original design is now barely legible, in terms both of geometrical patterns and the placement of trees and shrubs. They were rapidly becoming a derelict area. This intervention consists of their recovery by restoring the original vegetation by recovering still-living plants and introducing new ones. Between 2015 and 2019 the Gardens underwent complex restoration, carried out by the Foundation and planned by the gardener and landscape architect Paolo Pejrone, student of Russell Page and Roberto Burle-Marx, while architectural renovation and the rebuilding of the greenhouse was planned by architect Alberto Torsello, based on a project drawn up by Carlo Aymonino and Gabriella Barbini. Reopened in December 2019, the Royal Gardens, rich in unexpected perspectives and luxuriant growth, have reacquired their formal excellence and botanical complexity, in coherence with their historic nineteenth-century design.

As part of the EU Life+ CITYWATER project (of 3 cities), a sustainable stormwater management solution based on biofiltration was implemented in Maunulanpuisto Park in Helsinki, in order to purify rainwater and meltwater and improve water quality in the Haaganpuro Brook.
As the drainage area is heavily trafficked and paved with asphalt, high solid, nutrient and oil levels have occasionally been measured in the rainwater and meltwater entering the Haaganpuro brook. Such contamination is harmful to the fish stocks (e.g. trout) and other organisms in the brook. The biofiltration solution was the first of its kind in Helsinki. The solution also supported the City of Helsinki stormwater strategy, which aims at changing management towards sustainable solutions and states that stormwater should in first hand be infiltrated on spot, where it is created (ref. 1).
