The Liège Expo 2017 Masterplan was developed for the city of Liège, as part of their bid to organize the International Expo of 2017. In this plan, the Expo was not just an exciting stand-alone event, but rather the start of a sustainable transformation and an ecofriendly future of the city. The proposed development on both banks of the River Maaswill aimed to create new access to the river and improve the quality of life and the sustainability of the city, all at the same time (Ref. 1). While Liege was not awarded the 2017 Expo, the decision was made by the City to continue the competitive dialogue procedure initiated with a view to developing the Coronmeuse site into an eco-district (Ref. 12). Construction was launched in 2020 (Ref. 14).

The City of Milan intends to carry out a functional intervention in the valley of Ticinello for the strengthening of the environmental matrix and of the structural characteristics aimed at improving the ecological connection. The project, which aims to contribute to the valorisation, strengthening and conservation of the natural heritage, as well as expand local biodiversity, through the realization of terrestrial and aquatic ecosystems, is necessary for the realization, development and enhancement of large-scale ecological corridors already identified by the instruments of territorial planning (1).

In 2010 a very special orchard was inaugurated in the Park of Villa Ghigi in Bologna, the first of its kind in the region and probably in Italy, to preserve the germplasm of some of the oldest varieties of fruit plants in the Emilia-Romagna region. The Orchard contains about thirty fruit trees, organized into homogeneous groups: olives, pears, apples, rowan and smaller fruits. Each plant is accompanied by a panel describing the characteristics of the plant, the agronomic and the cultural aspects, including the tree and fruit picture (1).

INCREDIBLE EDIBLE (or "Incroyables Comestibles" in French) is an experiment of social innovation: the volunteers of the movement cultivate small vegetable gardens scattered in the cities and the countryside and make their products available free of charge (Ref. 1). This, the first intervention, took place in front of the "Epicerie du Coing" where volunteers planted several vegetables, flowers and plants (Ref. 2).

A new park was created through funding from the ERDF, as part of initiative “Building a Green and Accessible Urban Environment in Plovdiv”. The aim of the project was to provide a place for recreation and to help minimize the density of grey infrastructure in the central part of the city. Activities involved planting trees, as well as many shrubs and flowers. (Ref. 1)

The revitalization of the Saski Garden in Lublin in 2013 restored this space of local heritage historic character and cultural significance. Revitalization works included: cleaning and maintenance of existing trees and plants, planting extensive greenery, ICCTV and open access to wi-fi in the area of a renovated amphitheatre, revitalization of walking paths and ponds, small architectural elements like benches and a playground, and rainwater sewage system and a fountain [1,3,7].

The reserve is a biodiversity hot-spot within Cardiff Bay. The reedbed and other aquatic plants, are very productive vegetation and a habitat for birds. Prior to the construction of the Cardiff Bay Barrage, it was made up of mudflats and salt marsh. (Ref 1) The site was chosen by Cardiff Harbour Authority to create a new environment and compensate in part for the loss of the mudflats which were submerged after completion of the Cardiff Bay Barrage. Floating timber structures serve as breeding areas for birds, an underwater bund prevents wave erosion, and a boom keeps out waterborne debris (Ref 5).

An urban garden on a private citizen's terrace in the city of Aix en Provence, has been created with the help of the organization "Pays d'Aix en Transition" working towards permaculture and urban gardening. The main objective of this urban garden is to produce vegetables and fruit for personal consumption, to install plants in a very urban environment, and use permaculture techniques. Another objective is to grow climbing plants to decorate the walls. (Ref.1 )

Cardiff City Council and Urban Buzz brought together local organizations, community groups supporting wildlife, to create environments to encourage more bees, butterflies, hoverflies and other insects. (ref 1). One project inspired by Urban Buzz is Pharma Bee, a project housed and run by Cardiff University’s School of Pharmacy and Pharmaceutical Sciences, that worked to create a bee-friendly campus through their PharmaBees team (ref 7). In association with Urban Buzz, a project run by BugLife, it renovated the Cardiff University’s Redwood Building by planting bee-friendly plants (ref 2), installed beehives and trained bee-keepers (ref 7). The efforts were then expanded to the Hayden Ellis building on Cardiff University's campus (ref 7).

In 2013, St Davids shopping centre, which has over 200 stores and restaurants (ref 5) completed the installation of a green roof, which included bird boxes and beehives and the centre is looking to expand its green roof further. The city shopping centre has become the home of a 60,000-strong colony of bees. A second green roof was developed in 2015 in the parking garage to expand educational programs (ref 4). School children from Cardiff were involved in the planting of seedlings to create pollinator habitats for bees, butterflies and other local wildlife around the ‘Hayes’ area (ref 3). The customers and local community, with the help of this project, have been taught about the value of adopting an eco-friendly approach to public space. (ref 1)
