Green densification model

This NBS is part of a national campaign that was first implemented in 1936 and it deals with an entire month through which local authorities alongside public institutions proceed at plant a large number of trees. The action was resumed in 2008. The Forest Month, how it was named initially, has been over time an opportunity to raise public awareness of the importance of forests, and their essential role in maintaining ecological balance. The current name - Planting month Tree- is regulated by the Romanian Forest Code. (1)

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).

The project provides some improvements in the first part of the itinerary of the Navile river. In particular, it focuses on the restoration of the green system and the recovery of historical-architectural components in the area stretching between the Park of Villa Angeletti, the ancient village of Corticella and the municipality of Castel Maggiore. Restoring the route along the canal is the first step in an ambitious retraining hypothesis that sees Navile and its rich cultural and environmental heritage as the privileged axis for the recovery and development of the adjacent urban area (1).

The Project "Let's Open the Walls" is an integrated program of urban and social regeneration interventions that aimed to revitalize a portion of the Venice Commune (that is, one in the former neighbourhood Quartiere Due: Dorsoduro, Santa Marta, Giudecca, Santa Croce, San Basilio). The program, promoted by the City of Venice and funded by the Ministry of Infrastructure and Transport in 2004, provides for social inclusion and the weakest sections of the population and involved several interventions, including the planting of trees and the creation of green spaces for social activities. In particular, the Urban Italia program addressed to Venice is named: “Apriamo i Muri” (Opening the walls). It refers to the work-field “Quartiere 2” (District 2), in which are concentrated many actions that the city Administration has planned and approved during these last years. The Administration's objective was to transform and revitalize the degraded areas of the Venetian historical center, also through innovative actions. The program aims generally at urban, infrastructure and social regeneration of the Quartiere 2, moreover, it responds through articulated specific works to the critical complexity of the area.

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)

“Balne Lane Fields are an area of land close to the city centre of Wakefield. The site comprises of an area of nine hectares, which includes a former landfill site that has been restored to open green space. Part of the site is within a flood zone (Balne Beck).” “The field is popular with the local population for informal recreation. The potential to improve the variety of recreational uses, ecological value and environmental quality together with its links to both local communities and strategic greenspaces make it an important piece of green infrastructure in the City of Wakefield.” (Ref. 1)

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 )

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)

The Interpretation Centre at the Cardiff Castle is displaying a green roof of wildflowers. As well as changing the look of the roof, the wildflower meadow has increased the biodiversity of the area. The nectar-rich species of wildflower turf attract bees, butterflies and other pollinators. The roof had a simple irrigation system built into the substrate where the maintenance would be minimal (ref 3).
