Green Area Inner-city tree planting agreement
The project aimed to tackle two environmental problems through an integrated policy: climate change (both the mitigation and adaptation effects of urban forestation) and air quality. The project foresaw the dissemination of public-private partnership tools, developed within the framework of corporate social responsibility experiences, and the distribution of specific guidelines. Specifically, the project planned to develop a public-private partnership model for urban forestation through the adoption of the ‘green areas inner-city agreement’ (GAIA). This was expected to include three specific protocols for green urban areas covering management, monitoring and mapping resulting in 3000 trees planted across Bologna (1).
Historical rain gardens at the Great Mosque of Cordoba
The rain gardens of the Great Mosque give an example of a sustainable urban drainage system built 1000 years ago (Ref.1,8,9). The Great Mosque is a world heritage site by UNESCO (Ref. 1); therefore the rain gardens are protected and will continue to provide a sustainable irrigation system needed for the arid climate of Andalusia (Ref. 8,9).
Bundek Lake Cleaning and Renovation
Bundek Park is one of the urban planning projects aimed to create a recreational and sports area for the citizens and tourists to support a healthy lifestyle (Ref 3). The lake is surrounded by Bundek Park which stretches for 2,000 meters in length with an area of 35 hectares. The lake is about 5 hectares. the lake was initially used for fishing, walking and swimming. With the increased and carefree use of the lake, the lake and the environment became a waste disposal site. In 2005, by the decision of the Mayor, Mr. Milan Bandić, the renovation of Bundek began. The project included cleaning of the informal waste disposal site and shrubs blocking access to the lakes, renovation of the access to the lakes, planting flowers and introduction of the benches and water also to allow citizens to use the lake for recreation and enjoy the nature (Ref 2).
Air Pollution Garden
The Air Pollution Garden (APG) in the UK has been established at Sheffield Botanical Gardens through a collaboration between the three White Rose universities of Leeds, York and Sheffield. Typically an (APG) size is 6x8m and contains plants that are particularly sensitive to damage by pollutants like nitrogen dioxide (NO2) and ozone (O3) present in the air. The project owners hope to raise public awareness of air pollution effects in a tangible manner and change people’s behaviours (ref1).
In 2017, the city council hosted AirFest to push this initiative further (ref 8), a ‘Phyto-sensor’ toolkit was created by the Citizen Sense research group at the University of London to help identify the best locations for Air Quality Gardens (ref 6) and published the Air Quality Annual Status report (ref 7). In 2020 the project is considered as completed, although there are several different other projects in planning.

Pajaritos Neighborhood
This intervention is part of an action plan by the Junta de Andalucia to develop an intervention model for disadvantaged zones to facilitate the social inclusion of persons at risk or socially excluded, and the socioeconomic growth of the area. (Ref 1) The project is a pilot to transform one of Sevilla's poorest neighborhoods, Los Pajaritos, into an eco-neighborhood. (Ref 14)
Vertical Forest
This NBS is part of the new Porta Nuova area, an extended urban transformation of a neglected area of Milan. It consists of two residential towers of 110 and 76 m height hosting 800 trees and over 20,000 plants from a wide range of shrubs and floral plants distributed according to the sun exposure of the facade. On flat land, each Vertical Forest equals, in amount of trees, an area of 20,000 square meters of forest. In terms of urban densification it is the equivalent of an area of a single family dwelling of nearly 75,000 sq.m (3).
The ‘C/O City’ project
“The purpose of the C/O City project is to highlight the value of nature in the city, create planning documentation and develop concrete solutions that facilitate work with ecosystem services in urban planning.” The three phases of the project were to develop tools and methods, verify and adjust the tools and make them available to key actors. The final phase was to test the tools/methods and evaluate them. (Note: the starting point of the project was the environmental profiling of the Royal Seaport; i.e. Norra Djurgårdsstaden). Now as the project is completed, the results and lessons are continued by a non-profit association. The purpose of the association is to draw attention to and highlight the value of urban ecosystem services and contribute to increased knowledge in the public construction sector. (Ref. 1, 7, 8)
Vertical Garden
A 40 m2 vertical garden installed on one of the clinic's walls in 2012. It was the first vertical garden to be constructed in a hospital in Europe. It aimed to create a pleasant and relaxing atmosphere for visitors and patients at the clinic, improve the air quality and humidity of the complex and beautify the space of the hospital. (Ref 1) Over 1400 plants with over 40 species were included in the vertical garden (Ref 2).
Miraflores Park Córdoba
“The park, inaugurated in May 2003, [was] part of a 1990s project aimed at recovering the ancient canal, combining social needs and providing a space for citizens to spend their free time.” (Ref. 7) It is located on the south bank of the Guadalquivir river (Ref. 7), and today serves as a space for “leisure, sports, and intergenerational coexistence” (Ref. 1)
Living wall at the College of Architecture
The ‘Art Natura’ design was a submission to an ‘Ideas Competition’ for the Headquarters of the College of Architects of Córdoba. The design plan aimed to include nature in public spaces, through the use of a vegetal facade with a low irrigation system to transform the enclosure into a skin capable of compensating the differences of temperature and humidity in the different building planes. (Ref. 2)
