Enabling opportunities for physical activity

Initially the park was created in 1903 as a summer residence for the royal family and had a no-visitor’s policy. For over 40 years the park collected 821 trees, shrub and, grass species from all over the world on less than 100 ha. After the estate was given back to the successors of Tsar Boris III, they partially donated the park to Sofia municipality and in 2013 the park-museum ‘Vrana’ was opened for visitors. Due to its rare species, well-preserved wilderness and historical significance, the park enjoys great interest from tourists as well as scientists as a biodiversity hotspot. (Ref 1)

Revitalization of a large urban park in the Walle and Gröpelingen districts of Bremen. The current park constitutes a neglected area of the former port and shipyards sites with around 4,000 small garden parcels.The local government consulted with numerous societal actors the envisioned project, which aims at the revitalization of the park's both green and blue infrastructure. The goal of the intervention is to create a large recreational park for the districts of Walle and Gröpelingen, which will improve the image of the districts, help with their economic revitalization and provide sustainable practices for urban green care and community gardening (Ref. 2, 3). "Between September 2017 and September 2020, the Green West of Bremen was the focus of the federally funded project "Green Urban Labs" (Ref. 5). As of 2020, "Several of these building blocks have already been started or implemented and have led to an improvement in the cooperation between the actors on site, to an upgrading of the infrastructure and biotopes as well as to an increase in the popularity of the previously rather unknown area" (Ref. 5).

A project of the local government developed with EU and federal funds that aimed at the development of the green and beach area in the course of the refurbishment of the flood protection system. The initiative sought to provide a model project for urban flood protection, which can showcase that flood protection measures do not require a separation between city and water and new recreational spaces at the water and shore can be created instead. The project involves redevelopment of the shore area, enlargement of the public space at the shore with additional sand deposit and greenery planting (Ref. 1, 2). The bank area with a beach and recreational facilities opened in May 2019 (Ref. 5).

A pilot educational garden was created by Foundation Zaedno in Sofia in 2011 in the city kindergarten Slaveyche. The initiative was carried out with the financial support of Charles Stewart Mott Foundation and volunteers. The aims of the garden were to turn a derelict site into an attractive place for learning about and practicing gardening, playing games, learning about healthy nutrition, conservation, and promoting the creation of other Delicious Bio-Gardens. The garden has herbs, vegetables, and a rainwater harvesting system. Events connected to this initiative were taking place till 2013-14 (Ref. 1; Ref. 2; Ref. 4)

With the progressive monopolization of the seed trade and the industrial cultivation of hybrid varieties as well as the restrictive seed legislation, the cultivation of old crops has steadily declined and about 90 per cent of the old crops have been lost. This initiative aimed to reverse the trend by the cultivation of old crops, dissemination of their seeds among farmers and educational workshops to protect and increase their biodiversity.

The project involved the building of the propagation garden on an approximately 4500 square meter area in Ricklingen. This project started in 2013 and it involves interested residents, cooperating with Transition Town Hannover (TTH). The city of Hanover supported the initiative by providing the property and financial aid for the construction of the garden. The project has been provided with professional network from BUND (Kreisgruppe Region Han­nover), the School Biology Center, the VEN (Association for the Conservation of Crop Diversity eV) and Leibniz University, Institute of Horticultural Production Systems and the Chamber of Agriculture In 2014, the basic restoration work on the property was completed. (Reference 1, 5).
Frame beds were installed in 2016 while a garden house was built in 2017. The project was funded by the City of Hannover until 2017 but it continues until the present with the help of volunteers (Reference 9).

An intervention in the parks of Sintra relying on volunteer participation to eradicate invasive species from the green areas. The intervention was carried out on International Volunteer Day and volunteers removed the exotic weed species manually.
The manual work with volunteering was carried out in more sensitive places where herbicide can not be applied (water lines, protected habitats, etc ...) (ref.5)

The project is a close-to-nature maintenance concept that combines the diverse usage requirements in public green spaces and the promotion of biological diversity through near-natural care. (Reference 1) It aims to promote biodiversity in the area through the plantings of local trees, installation of deadwood stacks, dry stone walls and boulders, which will help in the increased interconnectedness of the green areas and provide for structured habitat for the local species. The initiative also involves development of ecological standards for the handling of green spaces in the country, such as natural care practices that will protect local biodiversity (e.g. adapted mowing regime for lawns, flower meadows). (Reference 1, 2)
The "Urban green - species-rich and diverse" project is a cooperation project of the alliance "Municipalities for Biological Diversity eV" (Alliance) and the German Environmental Aid eV and with the participation of the five partner municipalities Frankfurt am Main, Hanover, Wernigerode, Kirchhain and Neu- Response. The project is funded in the Federal Biodiversity Program by the Federal Agency for Nature Conservation with funds from the Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety. The experiences and results of the pilot project are further incorporated into the maintenance requirements for public green spaces in the urban area in other municipalities (Reference 1, 7).

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].
