Social cohesion

The Xochimilco borough of Mexico City is a World Heritage and Globally Important Agricultural Heritage System wetland site, with significant cultural and ecological importance in food cultivation and water ecosystem (1). Due to the deterioration of the area and lack of top-down initiatives for the restoration and conservation of the area, a number of grassroots initiatives trying to revive the traditional chinampa cultivation and restore the natural state of the ecosystem function and its native species such as the Xochimilco axolotl through reinvigorating sustainable practices that produce quality food and foster water supply. This NBS introduces 3 such grassroot intiatives: (a) Cooperativa Chinampayolo (b) Restauración Ecológica y Desarrollo A.C. (REDES) with its EcoQuilitl producer-consumer network and (c) Umbral Axochiatl A.C. (local community organisation). (1)

The creation of pocket parks is an urban initiative that has steadily grown throughout Budapest since 2010 (Reference 1). Most of these projects are citizen-led, but there is often support provided in the form of education and consultancy by initiatives such as the Contemporary Architecture Center (KÉK), or sometimes the local government (Reference 8). These spaces, typically covering an area of 1400 square meters only, are multi-functional and provide a space for small-scale food production, recreation, community sharing, and can be a fundamental element of neighbourhood rehabilitation. Moreover, it provides positive environmental effects such as water retention and the improvement of the area's micro-climate. Pocket-parks are critical in increasing the number of green areas in neighbourhoods that have limited space. (Reference 9)

After 2011, in the face of crisis and austerity hardship and the collapse of the central public welfare system, many municipalities assumed the role of enhancing food production through urban allotment gardens. In Ag. Dimitrios (AD), the idea emerged from a couple of newly elected representatives one of whom was part of an agriculture cooperative outside of Athens. A mixture of social and environmental goals were set (to change the microclimate, to change people's habits, to reintroduce contact with nature in the city, to be environment-friendly through good practices, and to create an educational ground for children).

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).

The two-year project "Integrationsgärten" aimed at the creation of three social integration gardens for refugees at different residential districts: transitional house Arbergen 2 (2016), a transitional house at Tannenbergstraße (2016/2017), and in Huckelriede (2017). The project involved various gardening activities and cultural events that aimed at increasing social integration of the refugees, improving their language skills, as well as stimulating neighborhoods to social engagement and participation in environmental issues in the neighborhood (Ref. 2, 3).

A pilot educational garden was created by Foundation Zaedno in Sofia in 2011 in the city kindergarten Slaveyche. The initiative was carried out with the financial support of Charles Stewart Mott Foundation and volunteers. The aims of the garden were to turn a derelict site into an attractive place for learning about and practicing gardening, playing games, learning about healthy nutrition, conservation, and promoting the creation of other Delicious Bio-Gardens. The garden has herbs, vegetables, and a rainwater harvesting system. Events connected to this initiative were taking place till 2013-14 (Ref. 1; Ref. 2; Ref. 4)

Rehabilitation of the public green space of the Park Krekovic through employment of people with a risk of social exclusion. The initiative cleaned the green areas of the park, rehabilitated the gardens with planting actions, and maintained the overall infrastructure. (ref 4)

With the progressive monopolization of the seed trade and the industrial cultivation of hybrid varieties as well as the restrictive seed legislation, the cultivation of old crops has steadily declined and about 90 per cent of the old crops have been lost. This initiative aimed to reverse the trend by the cultivation of old crops, dissemination of their seeds among farmers and educational workshops to protect and increase their biodiversity.

The project involved the building of the propagation garden on an approximately 4500 square meter area in Ricklingen. This project started in 2013 and it involves interested residents, cooperating with Transition Town Hannover (TTH). The city of Hanover supported the initiative by providing the property and financial aid for the construction of the garden. The project has been provided with professional network from BUND (Kreisgruppe Region Han­nover), the School Biology Center, the VEN (Association for the Conservation of Crop Diversity eV) and Leibniz University, Institute of Horticultural Production Systems and the Chamber of Agriculture In 2014, the basic restoration work on the property was completed. (Reference 1, 5).
Frame beds were installed in 2016 while a garden house was built in 2017. The project was funded by the City of Hannover until 2017 but it continues until the present with the help of volunteers (Reference 9).

The project "Sustainable Support Program for Greening Buildings and Minimizing the use of space using the example of Hanover" was established jointly by BUND (Bund für Umwelt und Naturschutz Deutschland) and the state capital of Hanover. The goal of the project is to transform as many barren house walls and dull grey roofs and asphalted areas into green oases throughout the city. Since May 2013, all house and landowners, housing associations and building communities have been able to apply to the BUND for a subsidy for green roofs and facades. On 2017, the project was expanded to include unsealing of areas like inner courtyards, driveways, etc, thus creating new green areas. Advice on the correct greening measures and on professional unsealing have been also offered by BUND.
The project is funded by the state capital of Hanover, the German Federal Environmental Foundation (DBU), the Sparkasse Hannover and by proKlima. The "Green Hanover" funding program will end on December 31, 2020. (Reference 1)
