Joint implementation (e.g. tree planting)

In 2017, Park Service of Portsmouth City Council has introduced a new approach to its annual 'In Bloom' campaign, aiming at increasing urban biodiversity, promoting pollinating insects and making the city more colourful (1,5).
As part of the initiative, 15 wildflower meadows have been created with information boards at various spots in the city including parks, gardens and schoolyards as well. Planted seed mixes had been carefully tested and selected to fit the local environmental conditions, including native species and promote pollination (5). The campaign has been appreciated by citizens and visitors of the Urban Meadows (5).
The urban meadows are planted as a part of an annual campaign (3)

In 2017, the municipality of Sintra approved the municipal Solidarity Gardens Program, which aims at enabling the inhabitants of Sintra to "value solidarity and, in some way, value natural resources" (ref.4).
This intervention aims to create small gardens in urban areas. Not only as a tool for subsistence for families in situations of social vulnerability but also to generate access to areas that tend to deteriorate, through correct management and profitability of resources. Eventually, the NBS aims to promote actions for the implementation of sustainable urban development, focused on strengthening family and local agriculture (1)

On the brownfield of an abandoned train station and its surrounding terrain, active citizens and neighbors developed Utopia town, a living lab for creative urban development, cultural and creative industries, and citizen engagement. Under the guiding principle “edible train station – edible town", next to other projects, an urban garden with organic cultivation was developed on 1,000 sqm of the terrain at the former train station Mirke as a focus area for their activities due to its favourable location in order to show that gardening is possible in urban spaces, even on balconies or terraces (Ref. 1, 2, and 3). The main building of the Utopiatown has a bar, a concert venue, a food sharing station, and a free bicycle lending service that is operated by volunteers. (Ref. 9). Gardening workshops that are offered to citizens with little experience of gardening are planned to be further extended with seminars and practice classes for students (Ref. 3). Since its beginning, the area of the “utopia town” has grown rapidly and is now providing opportunities for multidisciplinary academic research. (Ref. 12)

Students and teachers of the Faculty of Biology at St. Kliment Ohridski University created a habitat for birds, invertebrate species, and plants. The project aimed to popularise easy steps for increasing biodiversity in urban green spaces and effective practices for preserving it. The created habitat also aims to develop and solidify the biological and conservation knowledge of pupils, university students, and the citizens of Sofia, and to help restore the vanishing bondage between contemporary society and nature. Activities have included planting grasses and shrubs by volunteers, placing bird houses, and educational events. (Ref. 1). For the purposes of "Starling on the doorstep" volunteers among students and teachers of the Faculty of Biology began to develop some of the green spaces in front of the building by enriching the surrounding vegetation, and with it the diversity of animals. It was important for them that the transformation took place right in the yard of the faculty, where the future biologists are trained - the people called to take competent care of nature conservation. The idea for the initiative was warmly accepted by both the dean's management of the faculty and the ecology expert from the Municipality of Lozenets, on whose territory the school is located. (Ref 3)

The project has the goal to promote volunteering related to environmental protection. The community-based initiative involves disabled people to implement the intervention - with the supervision of specific tutors - to prove that they can be an active part of the population. Activities included taking care of several green areas and implementation of social horticulture gardens. (Ref.1.)

Following the Reading Growallot scheme, a derelict land area in Florian Gardens, Southcote was transformed into an allotment site. The scheme is part of Food 4 Families which is a community allotment project. One in four residents in Southcote live in flats with no garden to enjoy; local families have therefore transformed the land into a thriving allotment, growing fresh, healthy fruit and vegetables. This means that Southcote GrowAllot gives residents the chance to start growing food together. (Ref. 1, 3)

A communal bio-garden was created by a group of citizens in Sofia in 2014 on a municipal piece of land. The creation of the garden was supported by the Municipality through their programme “Green Sofia”. The aim of the project was to turn an abandoned and degraded green area into an “island of biodiversity” and a place for urban gardening. The garden contains herbs, vegetables, and flowers, dwelling places for useful insects, and a compost bin. The benefits of the garden have been ecological, educational, and social, including refugee integration. (Ref. 1; Ref. 2; Ref. 3; Ref. 4) According to their Facebook group in 2020, the 4 acre garden and the community that has organised around it is still thriving. (Ref 10)

The River Kennet and its tributaries make an excellent topic for introducing subjects to the curriculum at pre-school, primary and secondary levels. The ARK (Action for the River Kennet) project helps protecting the river and educate youngsters about the importance of water by providing educational projects for schools. The 'Trout in Schools' project as a partnership with Thames Water (funding and support), aims to hatch trout eggs and raise them until the trouts are grown enough to be released into the River Kennet (Ref.1, 2). The project has celebrated its 10th anniversary in 2018 and has engaged thousands of children (7).

The NBS was inspired by the first social garden created by citizens on Chrobrego Street. Later, the municipality provided funds for 4 additional projects. Social gardens were created in the housing estates of Wyżyny, Okole, Jary and Wilczak. Residents planted new bushes, flowers, trees, grass, and perennials, and arranged the existing nature in their pocket gardens. In some cases, they also established 'hotels' for insects and pollinators or created thematic paths. Common efforts are to grow healthy plants, herb and vegetable, and to create a friendly atmosphere in the gardens. The gardens are small, 100 square meters on average [1,4].

The urban gardening project is a strategic employment and qualification measure which accommodates 14 long-term unemployed people guided and advised by 4 part-time employees of the Wuppertal District Service, consisting of a professional gardener, an instructor, a social education worker and a project manager. Coordinated with the Forestry Department of Wuppertal and the City of Wuppertal and in collaboration with non-governmental organizations, the participants of the programme plant and harvest vegetables and herbs in 19 high-raised flower beds on decentralized public and private spaces across the Ostersbaum district. The harvest is distributed to and shared by all residents. (Ref. 3) A further goal of the intervention is to increase cultivated green spaces and streets in the city district of Ostersbaum and thus to enhance the quality of life in the district. In 2017, the project was extended with an opportunity for beekeeping. (Ref. 8) Apart from its main goal of providing employment and assistance to unemployed people, the leaders of the project also offer educational opportunities for children and students, through educating them about the cycle of food production and creating an understanding of the origin of food. (Ref. 1)
