Social cohesion

After Local Community consultation, a pocket park was created in Luton Millenium Green to facilitate community engagement and a sustainable legacy for future generations. The project included the installation of pathways, clear invasive vegetation, common vegetable planters, wildflower and enclosed areas and an orchard with 30 trees (ref 1, 3).

The project is an initiative that is part of the environmental management system of the University of Murcia. This initiative aims to implement activities related to sustainable agricultural systems while also serving as a space for social cohesion for the members of the community (Ref 3). For this reason, a community garden was constructed and the slots are until 2019 distributed between members of the community of the university based on a bid (Ref 1).

This intervention involved the removal of sediment and revitalization of the banks along with the rehabilitation of the urban part of the Segura River in Murcia. This was done to strengthen the environmental condition of the river and improve the visual aspects and the access of citizens to the river (Ref 3 and 7). In 2020, they are building the second part of the project, where the aim is to build three different walkways that join the two sides of the rivers and that will connect specific places along with it (Ref 5).

It is a community garden initiated by the autonomous assembly of the Poblenou neighborhood. It has changed location a number of times, eventually occupying the empty lot of demolished buildings. Over time the garden has expanded, taking over an adjacent empty space, as well as other yards in the neighborhood. The garden is not maintained for strictly productivity purposes, especially because much of its soil has been contaminated by a soap factory. It is, rather, used as a space for social encounter and knowledge sharing on planting and working with the earth on a communitarian basis (Ref 1 and description provided by CEU). This NBS is also part of a wider movement, the 15M movement in Spain (Ref 1), which had influence on the creation of larger similar global economic 'occupy' movements (Ref 5). Video for the opening party of the 8th self-managed squatted garden in the Poblenou neighborhood, Barcelona from April 11, 2020 shows that the idea of the first garden has lead to the creation of at least 8 of these gardens in the city (Ref 6).

The Parc Agrari del Baix Llobregat is located in the floodplains of the delta and lower valley of the river Llobregat, in the Catalan county of Baix Llobregat, in a central position within the metropolitan area of Barcelona. The territory of the park (nearly 3500 hectares), includes a rich traditional agricultural activity and comprises fourteen municipalities totaling about 818,000 residents. It is protected by a specific planning instrument and managed by the Barcelona Provincial Council (Diputació de Barcelona) (Ref. 1 and 9). The park acts as a green lung for the metropolitan area of Barcelona and at the same time as a pantry for Mercabarna, the large wholesale market that provides food and drink to the inhabitants of Barcelona and surrounding towns, although there is also production that is exported (Ref. 10). The Agrarian Park is the only one in the world so close to a large city and it promotes specific programs to preserve the productive values of the agricultural space and promotes quality local products and local consumption. (Ref. 10)

The Hort de la Masia de l'Antic Jardí Botànic is located within the city’s largest inner-city park Montjuic. It has been founded in 2008 by an association of volunteers and is supported by public and private entities. The garden is co-management by members of the association and a professional gardener. Its major objective is the maintenance and reproduction of traditional landraces (Ref. 2). The task of the Citizen's Commission of Support of the Botanical Garden, presided by Pere Duran, was supported by the promotion work from the Botanical Institute. It was therefore a necessity generated by a local group of people (citizens) that developed into an implementation plan (Ref 1).

This is a co-management initiative fostered by the City Council of Barcelona that aims to involve civil society in defining, installing and managing unused spaces across all districts of the city. The city council provides temporary use for public entities or non-profit associations to develop temporary uses and activities (from one year to three renewable years) in order to promote social activism and cohesion in the neighborhood. Most part of activities are social urban gardens (Ref 1). The initiative had 2 editions, with 12 projects in the first one (2013) and 5 projects in the second one (2015) (Ref. 12). One of the most popular projects is the community gardens such as ConnectHort, in Poblenou, dedicated to permaculture, which has allowed the restoration of an abandoned area through sustainable urban agriculture practices (Ref. 12). Another project, the Illa dels Tres Horts project in the Font de la Guatlla neighborhood, is an orchard where work is done with vulnerable groups and allow the recovery of vulnerable species (Ref. 12)

The gardens of the Rambla de Sants is an elevated linear park (similar to the High line of New York) located in the Sants district of Barcelona (760 meters long and about 6 ha size). It is located over the structure of train and metro lines. It was opened to the public in August of 2016. The gardens include mainly native plantations, playground areas, and other facilities (Ref. 2).

Fil vert aims to help green the streets in Normandy and raise awareness among citizens of the importance of being an actor of their daily life with regard to the occupation of public space. They aim to "embellish our streets, which are often devoid of vegetation, but also to train responsible citizens" (Ref. 7). "Operation "Fil Vert" was launched at Croix de Pierre (District) in Rouen in September 2013 to beautify and revitalize the district by mobilizing residents and tradespeople. It aims of installing planters in front of the inhabitants and the merchants (subject to obtaining the agreement of the owners in case of hiring), along the pavements, provided that it makes at least 1.40 M width to allow strollers and wheelchairs to pass." (Ref. 3)

The Senate of Hamburg commissioned IBA Hamburg GmbH with the development of the project which aims at realizing two new, family friendly residential districts in Neugraben-Fischbek, the Fischbecker Heidbrook and Fischbeker Reethen, which will offer 3000 residential units in total. (Reference 10) Out of the two districts, Fischbeker Reethen is planned to be the "Garden City of the 21st century", which is why this NBS case focuses on that project. The Fischbeker Reethen project pays attention to sustainability, having a blue-green infrastructure (large green surfaces, waterways and a lake that serves as a basis for the rainwater management of the area). A further aim of the project is to create a new district for the growing city, that with its good infrastructure, public transport connection and educational offers will help the integration of refugees into German society. (Reference 12) The construction of the buildings followed by the green and recreational elements is will start in the second half of 2020, and the handover is planned for 2022 the earliest.
