The Royal Society for the Protection of Birds (RSPB) ran a project to turn Belfast into the first-ever “Swift City”. The Belfast Swift City project aimed to bring nature back to the city and protect the swifts (ref 1). The aim was to find out where the birds are nesting, so work can begin to protect them. Additionally, there was said to be potential for the creation of community gardens in the area of residential buildings undergoing regeneration to aid this project. (Ref 2). As thousands of swifts migrate from Africa and nest in crevices in buildings, nesting boxes were put in a few locations like the parliament building to attract more swifts. (Ref 4)

The Foz do Douro Urban Park located in the west of Porto city is a green area for public use inserted into a recently developed urban area, which has been progressively been built along the Atlantic seafront since the nineteenth century and the Park is part of an overall project submitted in the competition Nuno Álvares Avenue Plan promoted by the Porto Municipality. With approximately 5ha, Foz do Douro Urban Park clearly contributes to increasing the rates of existing green areas for public use, increasing the availability of open spaces for the local and regional level.

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)

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].

Following a severe storm in 2000 that overwhelmed the sewage system of Portsmouth along with its main Wastewater Pump Station, causing major flooding in the city with the destruction of private and public properties, prevention of such events become a key priority (5).
The Portsmouth Flood Alleviation Scheme aims to relieve the pressure on the sewage system in wet weathers by diverting the accumulated surface water flows away from the combined sewer networks and discharge them into the harbours around the island (5). The Scheme consists of several measures across the city, among others the creation of a new open watercourse channel across the Great Salterns Golf Course diverting surface water directly into Great Salterns Lake (5). This measure of the scheme is a solution that separates surface water to provide resilience, boost flood protection and benefit the environment with the minimum of new infrastructure (1).

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 NBS is a large green roof on top of "ATRIUM PARK", which is a modern neighbourhood of 4 buildings in Bydgoszcz. The spacious green park of 5,000 m2 is located on the roof of a multi-storey garage that extends under all buildings. It is divided into zones: a playground, an area for active recreation, and the relaxation area. The description of the project stresses its beneficial effects on the health and well-being of the residents [1].

Focus Park is a large shopping mall with green terraces (900 m2) and green walls in the city of Bydgoszcz. The project serves marketing purposes – the green areas outside the mall are visible from various vantage points. Due to the selection of pollution resistant plants and installation of an automatic irrigation system the project also involves water retention and supports local biodiversity and good air quality [1].

A rehabilitation clinic in Bydgoszcz opened a rooftop garden for its patients. The garden was established in 1998 on the total area of 1 790 m2. The initiative was created with children of the Paediatrics Clinic in mind so that they could look at the garden instead of a concrete roof from their windows. Plants were designed in a way that their fragrances and colours are respective of the time of the day and the year. The spruce was also planted in the garden to be decorated as a Christmas tree in winter [1].

The NBS is a 200 m² green roof created as a complementary element to the concept of a low-emission building of the Demonstration Centre of Renewable Energy Sources at the School of Mechanical Engineering No. 2 in Bydgoszcz. The roof serves as a recreational area for students and visitors, provides thermal insulation for the building, increases biodiversity and improves the image of the construction [1].
