The Roerplein pocket garden was a Neighborhood Green Plan project. The Neighborhood Green Plans were an initiative of Utrecht Municipality to support the bottom-up 'greening' of its neighbourhoods. Citizens could propose a variety of often quite small-scaled plans that enhance the neighbourhood by means of green spaces that promote social cohesion and thereby community identity. At the Roerplein, a public square was transformed into a green square by way of a participatory process, assisted by a social entrepreneur. The project aimed to reduce heat stress, enhance social cohesion and the attractiveness of the neighbourhood, promote biodiversity and support recreation (ref. 1).

The Tree Strategy is a municipal action plan in progress, aiming to address some of the main sustainability challenges described in the Environmental Program of Malmö City. Its main relations to sustainability challenges include improved health and well-being, decrease differences in those among different social groups and increase biodiversity. The Strategy includes a range of possibilities for evaluating its ecological and social success (ref. 1).

Initiated by the City Administration, NGOs and citizen groups, public funds have in recent years been used alongside partnerships with local businesses, landowners and citizen initiatives to invigorate the East Quarter. This initiative was proposed through the redesign, extension and new development of parks, greening and communal use of vacant plots, the establishment of new urban forests, the setting up of new communal gardens, and the planning and partial implementation of a green corridor for cyclists and pedestrians.
Within this large project, three NBS areas actively contributed to the improvement of the Quarter: Querbeet, Bunte Gärten and Parkbogen Ost (1).
Querbeet is a community garden in the Eastern district of Leipzig, formed in 2012. The garden is lead by democratic self-governance principles where the focus is on shared space, with a focus on enhancing cultural interactions and encouraging active citizenship (1). Since 2017, the plot of the garden has reduced, however, the non-profit organisation formed two new gardens: a community garden and a school garden where environmental education the main activity (2)
Bunten Garten (Colorful Garden) is a community garden and registered refugee aid association that aims to bring residents and refugees together (3) The garden was revived in 2015, and since offers opportunities for recreation, wellbeing and informal support to refugee families (1).
Parkbogen Ost is a scheme focusing on developing unused railway tracks as an arch-shaped, green mobility corridor running along the perimeters of much of Leipzig’s East Quarter and connecting the quarter’s green spaces and providing easier access, by foot or bike, to the city centre as well as to surrounding areas.

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)

The School Garden of Széchenyi István University, Apáczai Csere János Faculty in downtown Győr was reestablished by the Vice Dean of Apáczai in 2013. Apáczai’s new school garden trains university students studying education on properly organizing and maintaining the school garden with ecological methods in the format of an optional credit course at the university. Alongside the university students, elementary school student groups are responsible for the planting, maintenance, harvesting, seed collection and other activities under the supervision of teachers and in Apáczai’s garden. The modern school garden movement is rapidly growing since 2013 due to its recognized value in current pedagogical movements, and role in education for sustainability (Reference 1). In 2019, a raised garden bed was also added to the garden, which made that part of the garden accessible to wheelchair users as well. (Reference 2)

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 local government-led project of the renaturalization of the part of the Weser river shore. The initiative aimed to restore part of the river bank to its natural state and to create habitats for the typical local flora and fauna. Additionally, a sand beach for the public was created. The project aimed to increase biodiversity, increase the river shore protection and water management, as well as to improve public access to the recreational area at the water and the attractiveness of the river landscape (Ref. 1, 2, 5).

A private investment project that aimed to create a new building complex in the Findorff district of Bremen and build two large residential buildings "Münchner Bogen" and "Findorffer Tor" with green roofs on top. The green roofing of the buildings was influenced by the local actors - the alliance "Green Bremen" and the advisory board of the Findorff Council. The initiative aimed to contribute to sustainable urban development by the positive impact on biodiversity, rainwater retention, improved local air quality and provision of natural thermoregulation for the buildings (Ref. 1, 2, 3).

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).

The Belvedere College Urban Farm is run by students from the school and by the Urban Farm start-up. The complex consists of a greenhouse and an open farm, both situated on the rooftop of Belvedere College. The project serves as a testing ground for researching sustainable farming practices, provides education and practical experience on the topic to students, and is part of a collaborative food network in the local area.
