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)

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).

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.)

In 2011, the Great Lines Heritage Park was formed by connecting the Great Lines, Lower Lines, Inner Lines, Forst Amherst and Medway Park together. To do so, a former military area was transformed. The intervention connects the heritage towns of Chatham and Gillingham and the Chatham Waterfront. By connecting the heritage of the town and the waterfront, the project aimed to emphasize both these aspects of the area, but also to improve visitors' access and be a habitat for a number of species (Ref 2). The area has been created from a site that is of international heritage significance. The park is located within the Thames Gateway priority housing area, Europe’s largest regeneration project (ref. 3).

This intervention is part of a broader masterplan regarding harbours and seacoast in Palermo, with a specific focus on the Cala coastal area. The waterfront has importance for the city not just as a harbour, but for its relational, cultural and recreational functions as well. In particular, the Molo Trapezoidale can become the new “water district” in which compatible port functions will be integrated with the existing urban functions and the new residential areas, as well as the new cultural and recreational services with new infrastructures linked with natural features such as green areas and trees. (Ref.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).

New recreation zone "Norikus Bay" in Nurenberg was completed in 2018 on the south bank of the Wöhrder lake, an artificial lake created in 1968 to protect the city from flooding. The dam itself, which is a 400m long path separating a part of the water surface from the bigger part of the lake, has become a tourist attraction with a water playground and other recreational amenities being offered. The water is naturally cleaned through the regeneration zone with natural plant filter, and simultaneously improves the habitat of fish and makes recreational swimming in possible in the cleaner water. New green areas are organized on the shore in order to improve environmental, aesthetic and recreational conditions of the area (1, 7, 8).
