Social cohesion

Collaboration between the City of Aarhus and private property developer DOMIS Ejendomme has been recognised by the award of a silver certificate for sustainable urban planning for the Bryggervej project. The aim of the project is to try out various sustainability principles. Green and blue solutions are included in the project, e.g. green roofs, green facades, green open spaces and blue elements/water in the park areas to increase recreational values and add moisture to the dry urban air. (Ref. 1, 2, 3)
By 2020, the first residential project was built called Risskov Brynet (Ref 8). Information in the project since 2017 is about this project. The project is certified according to DGNB Gold because it is based on a high standard for both social, economic, and environmental sustainability. An important part of this project is a 'highly insulated climate screen', a technology of the project that is incorporated into the project to address climate change (Ref 8, 9, 10).

The Community Supported Agriculture initiative in Bonn (SoLaWi Bonn) is an economically motivated arrangement between consumers, farm businesses and certified gardeners to improve the urban provision of local, organic food. Together they develop a concept for collaboration where the consumer group commits to pay an annual fee to cover all of the farmer's expenses for production (according to individual financial capabilities) and to work placements at the farm per year. In exchange, the customer members of the initiative receive a variety of fresh, seasonal, locally produced vegetables. The farmers profit from financial security and economic stability and the ability to apply environmental friendly agriculture practices without the pressure of the market economy (1,4).

Along the 'Green Belt' (Grünen Band) in Bielefeld, which connects several urban grave lands with a continuous path, the organisation of Transition Town Bielefeld created a community garden to replace the permaculture garden in Bleichstrasse. (8) Thanks to its location, apart from the food production, the garden increases the environmental quality of the site serving as a green transition between the grey areas and the city. This function is in line with the overarching mission of Transition Town Bielefeld to promote energy and cultural transition in the city through different initiatives. (7) The community garden initiative was started in 2013 and welcome citizens to take part in the maintenance, planting and other gardening work of the garden or simply to enjoy its beauty since its launch in 2015. The project has a bigger goal towards sustainable development of urban infrastructures and social equity (1,2).

The garden was established in 2012 by self-management of the community of Exarcheia. The site is a former parking lot in public land, historically reclaimed by the neighbourhood as a green zone. People occupied the space, designed the park, and constructed it. The former parking lot was owned by the Technical Chamber of Greece (TCG). A weekly assembly manages the site and activities. The aim of the community garden is formative, to show how to grow food, reproduce and collect seeds. The park has encompassed multiple functions in addition to community food-producing garden, such as children's playground, a place for cultural events, gathering and emancipation (Ref 1, 2, 3).

Restructuring a public derelict land into few private vegetable and fruit gardens. The gardeners practice organic gardening making it more sustainable. This provides foods as well as increasing the soil fertility, and reduction of the soil erosion. This also creates some extra vegetable and fruit market in the city. 20 % of the food produced is donated to the food bank. The project is a community project which also helps to bring people together. Started in April 2012 (Ref 1,4). The project is one of the initiatives by the Greek municipalities allotting land to local citizens with the purpose of increasing food security for the underprivileged, educating the younger generation, and providing their citizens with a retreat from city life (Ref 3).

The intervention included the renovation of lake Jarun and its surrounded park and recreational centre. Efforts were made to improve the amenities at the lake and park in order to bring it closer to the citizens, particularly to disadvantaged groups. It provides facilities for walking, bicycling, various outdoor sports, trim-track of 6500 meters of length, roller skating, etc. Sports facilities are related to an impressive 2250 meters long regatta path where international and world rowing, canoe and kayak contests are held. With daily training and performances, they give Jarun a special, sporting atmosphere (Ref 1, 2, 3, 4).

Since it's founding in 2005, the association "Ermekeilinitiative e. V." has been aiming at the transformation of the Ermekeil quarter, a former military base to a communal, generation-wide and intercultural space with diverse ecological and sustainable use. Since the Federal Office for Defense Administration moved out in 2013, the territory was released for interim use. Together with residents and communities, the association turned the territory into a lively, green and mixed neighbourhood with several initiatives taking place in parallel. The community garden project was one of them (1).
The interim use of the area ended in 2016, some of the buildings of the former military base have been sold on the real estate market. This resulted in the termination of most of the Association's initiatives in the area including the removal of the 100 raised beds of the community garden. Parts of the community garden was relocated to a different part of the quarter, however, since 2018 there is no information on the current working and management of the community garden (2,6).

The Bohnenback Park project was one of the first urban redevelopment measures in Bielefeld and was opened its gates for the public in May 2017. The park is the combination of blue and green areas in the Bethel district. It was created by exposing the Bohnenbach stream which previously had been piped and been flowing underground. The park consists of free, bright spaces and lawns with few individual groups of trees. Along the naturally meandering course of the brook, there is a long, north-south oriented promenade, which also forms the backbone of the park. It separates the neighbouring buildings from a parking lot while also connects the Bethel district to its surrounding areas via a green corridor favourable for recreation (1, 7).

"Micro-flowering are participative urban gardening projects that allow the vegetation of streets by small plantations of annuals and perennials, vegetable and ornamental, in the municipal public space. Generally, it is a matter of developing a mineral surface on the municipal surface of the city by planting pockets. These are then maintained by the inhabitants who requested micro-flowering. Micro-flowering is a place of sharing and conviviality that allows the inhabitants to be actors of their neighborhood" (Ref. 1). In 2018, formalized 'greening permits' were launched. In this system, micro-flowering permits are requested by residents and "The municipal agents come to drill the concrete of the sidewalks and the City provides the plants" (Ref. 9 and 11).

The Anfield Regeneration project was founded in 2013 with the aim to improve the area and its neglected housing stocks. It was set up by the Liverpool council and the Liverpool Foot Club, along with developers Your Housing Group and Keepmoat. The activities include the development of new and refurbished housing, the development of a new public square including commercial and retail premises, a revitalised high street and the expansion of Anfield Stadium (Reference 6) . It also includes the creation of public spaces and selective garden extensions in the area following the demolition of a number of derelict homes (Reference 1).
The partnership has stated that more than 600 new homes have been built, with 600 existing properties refurbished. The project aims to create 1000 new homes and is scheduled to be completed in 2020 (Reference 6, 8).
