Green space and habitat

A project began in June 2017 to plant grass, flowers, trees, and shrubs on 10 hectares of “muddy spots”, or unused lands that were being eroded and increasing of dust particles in the city. The aim of the project was to improve the air quality and stop these muddy areas being used as unregulated parking spots. The project was initiated and is partly implemented by the municipality, while volunteers also took part in the initiative, brought together by the citizen group called When we Become 100 000 – we Will Plant a Forest. The project planned to use compost from the new composting facility in Sofia, which reuses food waste. (Ref. 1; Ref. 2)

‘Colorieten Hof’ is a community garden in which vegetables, herbs and flowers are grown sustainably. The garden is a social meeting place for elderly, neighborhood citizens and female immigrants who can learn Dutch and about Belgian culture (Ref. 1, 3).

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)

This intervention was a proposed citizen project to connect the southern districts with Murcia by converting the abandoned railroad tracks into a green corridor. The intervention aims to transform the abandoned space into a green mobility corridor for various forms of transportation, from public buses to bicycles, and for pedestrian and leisurely use as well. (Reference 1 and 2). In 2019, there was the opening event to show this Green Corridor's construction, which is now the longest in the region.

The municipality aimed to establish a zone in Murcia that worked as a "green lung" for the city while making it its engine for economic, social and cultural development (Ref 2). For this, the municipality planned and implemented the project of "Integrated Alcantarilla Parks". It includes several parks, with the priority of creating one in the surroundings of the Ethnological Orchards Murcia's Museum (Ref 1). The project is called integrated as it is based on the integral values of sustainability where the environment, the economic development and the socio-cultural needs are compatible (Ref 2). For this, there will be sustainable architecture, recovery of the natural environment, as well as incorporating the historical heritage in the public green areas of a specific zone (Ref 3). There are many parks that are part of this project, the last one was the Ibarra de Murcia Park in 2020 (Ref 7 and 8).

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)

A green roof of the total area of 362 m2 was established in a modernized historic neighbourhood in the centre of Bydgoszcz. The rooftop serves aesthetic and recreational purposes for the residents and visitors. Selected plants retain as much as 40-99% of rainwater and absorb air pollution [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 area of the Port of Antwerp is one of the most important habitats for threatened species, even at the European level (Ref. 1). Therefore, a species protection programme was launched in 2014 for the conservation of 90 protected species by means of creating an ecological infrastructure of green areas, green corridors and small green spaces that include spawning grounds, ecological river banks, and road verges (Ref. 1, 2, 3).
