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 City Council has passed an ambitious woodland plan designed to protect the municipality's groundwater.By planting woods in vulnerable areas where boreholes have been drilled for drinking water, the use of pesticides or other pollutants in the immediate area can be avoided. Aarhus residents will be ensured clean drinking water in 20 years even though the population is rising.(Ref. 2) New woodlands west of Aarhus will be a magnet for lovers of the open air, and secure clean drinking water for the city's population.(Ref. 1)

In 2002, the facilities of the Bielefeld Botanic Garden was expanded with a small apiary for local bees. The apiary was opened on the 90th anniversary of the Botanical Garden and since then in its 5 beehives accommodate the bees living in the garden. The facility is a place for breeding of bees to support their pollination activities and thus their role in food production while the apiary also offers visitors the chance to get an insight into the life and work of a beehive. Through various environmental educational programs, visitors and school children can learn about the importance of bees and the process of honey making. Beekeeping stations were also installed in other surrounding areas such as cemeteries, old dumps, fenced rainwater retention basins. (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 Lez is a small Mediterranean river 28.5 km long, born from a karstic exurgence whose supply zone extends north of the source, over more than 150 km2. The “Le Lez” site was proposed in February 2001 because of the presence of several species and natural habitats protected at European level. The designated part concerns the upstream course of the Lez river, its riparian forest and associated agricultural environments. Covering an area of ​​144 hectares, the area stretches over 14 km from the Lez sources in Saint-Clément-de-Rivière to the Concorde bridge, in the town of Montpellier" (Ref. 4). Strong economic and demographic development near Le Lez implies urban pressure on peripheral sectors, particularly north of Montpellier where many residential areas are developing. The river became protected thanks to the "Natura 2000 European network" which aims to reconcile human activities and the conservation of biodiversity on the basis of the main principles of sustainable development (Ref. 4).

The agriparc of the Mas Nouguier is an agricultural reserve entirely maintained by the city of Montpellier. Conducted in organic agriculture, the estate contributes to the preservation of the identity of the territory and to the valorization of the living environment. Accessible to all, it offers a beautiful walk in the middle of the vineyards. Apiaries are used to develop educational workshops and to collect honey with school children. Olive trees, centennial pines and a large meadow come to embellish this little bit of countryside in town (Ref. 1).

The current intervention involves restoration of Bohrova park in the city district of Petrzalka with the implementation of water conservation measures (9).

The planting of trees and shrubs in Dolnozemská Street is part of the Bratislava zelenaj project and Bratislava’s gradual implementation of NBS to mitigate the negative impacts of climate change on its inhabitants. (1, 3, 9)

The revitalisation of the park Gaštanica Koliba in Bratislava Nove Mesto is intended to stop the degradation of its ecosystem, preserving existing vegetation while improving the local climate and efficient use of rainwater. Over 100 trees were treated, including some of the local population of chestnut trees. A local seepage pit was installed to retain water both to the benefit of the local vegetation as well as to prevent erosion and landslides. The park has also been fitted with recreational facilities and is now illuminated to improve its accessibility for the local population. (7, 8, 9)

"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).
