Sustainable production

The Desjoyaux ZAC in the Crêt-de-Roc district, was created in 2005. Since then, this three-and-a-half-hectare site, which is involved in the process of receiving the "eco-district" national label certification since 2015, has metamorphosed (Ref. 1). Some works aim to renew and embellish the public spaces located near the residences of the street and the impasse Desjoyaux to preserve biodiversity in the city center of Saint Etienne and for the well-being of citizens. (Ref. 1, 2 and 3). Community gardens, park, ephemeral gardens, swales and sustainable water filtration system are being developed in this project (Ref. 1, 2 and 3).

In 2007 the Lisboa City Hall began the development of a strategy for urban agriculture, having created in 2011 several allotment parks. Beyond the provision of plots, the Council also provided the fences, shelters for storage, water irrigation, training and technical support. In 2011 there were already 56 plots of 150 m2 at a location named Granja Farm (2)

"On June 1st 2017, Saint-Etienne Métropole officially committed itself to the implementation of measures to promote the circulation of wildlife between the different green spaces with important biodiversity in its territory" (Ref. 3). "Saint-Etienne Métropole has signed with 13 partners a new contract called "green and blue". It is a new blue and green framework for the whole territory, a regulatory tool for the protection of biodiversity" (Ref. 2). "It aims to continue and reinforce the actions already undertaken with a transversal and urban dimension" (Ref. 2).

The "PROSIT" project aimed at undertaking a series of actions based on environmentally compatible mechanisms to protect and recover the coastal rural territory of Cinque Terre. Today, the terraced landscape is characterised by intense processes of land abandonment and disuse, caused both by practical and economic difficulties of maintenance and by social changes. There is a risk that the damage caused by land abandonment can compromise the area's delicate hydrogeological balance, especially in an area where landslides and floods are highly common (1). A demonstration project to recover abandoned terraces was carried out in five areas of the park (1).

The green area which surrounds the famous museum has been renewed in the last years. It is an interesting site of botanic interest, as there are more than 400 species of plants living there, and more than 150.000 trees. In particular, the company Slow Food Campania cultivated a small vegetable garden. Is a project of small- scale agriculture, in order to enhance a variety of cultivation and biodiversity conservation. The company Slow Food has been supported by the company Lande srl, specialized in the revitalization of historical green areas at the urban level (Ref.1).
The interventions include the restoration and re-functionalization of 10 areas: the Garden and Casamento Torre, the Giardino della Fruttiera di basso, the Fagianeria, the Capraia, the Porta di Mezzo, the Cisternone, the Cellaio, the Vallone di San Gennaro, the ex Eremo dei Cappuccini (Ref.1).

The OrtoCollettivo project focuses on the creation of common spaces to grow local sustainable food while raising awareness about environmental challenges in cities. The project is based on teamwork: if there is work planned for today and someone cannot come to do that job, someone else will do it, with the ultimate benefit of everyone. It, therefore, stimulates common values about well-being, sustainable food production, and sharing time and activities collectively as a group (2). The initiative is ongoing and expanding, however in 2020 there were voices from the people living in the area that the poor maintenance of the terraces caused landslides and disturbed traffic. Nevertheless the NGO that initiated the intervention defended the project and suggested that the issue is caused by the lack of canals for the rain water to flow in. (8)

The association Initial Karlsruhe initiated the "social garden" in 2009 with the objective to facilitate access to the labour market for disadvantaged individuals by providing employment for long-term unemployed individuals with gaps in their CV. (Ref. 1) The participants can work on a 6000 sqm large former agriculture area up to six hours per day under the supervision of an agrarian engineer and a professional gardener. Harvested products are delivered by bicycle to charitable organizations free of charge. (Ref. 2, 9, 10)

O'pflanzt is! is a community garden in the inner part of Munich. It was founded in summer 2011 by Vanessa Blind. Her vision was to create an urban, socio-ecological community garden - a place of planting, sowing and harvesting, a place for meeting and learning, a piece of nature in the city, a creative wilderness. The garden is a real community garden, as there are no individual beds, and decisions are made collectively. Sustainable production is one of the main goals of the project, which is why planting is done organically without synthetic fertilizer and only wood and recycled materials are used. (Reference 2) In 2018, the area of the garden had to be returned to its owners. The leaders of the garden, however, managed to find a new plot within a year and a half. (Reference 13)

"Pending the creation of housing and new walks by 2020, the association Carton Plein and the EPA (Public Building Institution) of Saint-Etienne have created a temporary public space on the site known as "la Cartonnerie". A place for exchange and conviviality, the site hosts artistic installations, ephemeral installations and events. It is a laboratory conducive to imagining new ways of doing the city" (Ref. 1). The citizens also created shared gardens in this area called "Le Jardin Experimental"(Experimental garden) (Ref. 4).

The Montreynaud Park is composed of a great diversity of spaces (dense woodlands, undergrowth, meadow spaces, small group of trees ) and presents a richness of fauna and flora. The challenge of rebuilding this area is to create a real urban park, a green lung that provides the junction between the upper and lower parts of the neighborhood and links it to the rest of the city. The redevelopment of the park must meet the needs of the inhabitants by developing a place of contemplation, pedestrian paths, sports and recreational paths, and in connection with scientific, technical and industrial culture (Ref.1).
