'Nature Island' Community Garden - Pennenfeld, Bonn
The Nature Island Pennenfeld-Bonn ("Naturinsel Pennenfeld") is a community garden project of the Lebensqualität im Alter - LeA (Quality of Life in Old Age) Association, the District Management (QM) of Pennenfeld and the municipal housing company VEBOWAG (9). The project started in 2012 and its aim was the transformation of a 1,800 sqm large tree-lined lawn area (9). The lawn was to be transformed into a park-like natural community garden for recreation where elderly residents have more opportunity to experience nature, while at the same time it is a place of encounter that promotes social stability by encouraging all other residents to get engaged in the planning, implementation and maintenance processes (1,3,9). Besides enhancing the quality of life for residents and elderly people living with dementia, other project objectives were to foster and increase the local biodiversity as well as to strengthen community building and mutual support in the neighbourhood (2).
Green wall: Eiffel Palace Office Building
The 53 square meters large green wall can be found in an office building in the center of Budapest. (Reference 9) It helps to balance the humidity indoors, cleans the air and provides a comfortable work environment. The project includes rainwater collection for the irrigation of the green wall. (Reference 6) The building itself was the first one in Central-Eastern Europe to gain the double environmental certification of BREEAM Very Good and LEED Gold. (Reference 9) The focus of the NBS are the indoor green walls, but the building itself also features vegetation on multiple terraces and sun collectors. (Reference 10)
Agora Budapest: the new citycenter
Agora Budapest is a large scale urban redevelopment project initiated by private investors. Besides implementing five high-quality office buildings, the investors aim at creating green public spaces the size of 7000 square metres in order to provide a healthy and vivid working environment. The green surface involves green roofs, parks and tree lines, all which will be irrigated using collected rainwater. The solar panels on the roofs of the buildings are also part of the sustainability plans of the investors. (Ref 1. and Ref 4.)
The Sprouting Building
The Sprouting Building is an apartment complex which was built in 2000 in such a way as to have seeds grow from the exterior walls of the building. "There are "balcony-gardens" to dine in with many friends, "balcony-cabins" perched among the trees for more intimate encounters, "balcony-lookouts" to curiously explore the foliage of the treetops, and "balcony-terraces" for reflection and contemplation. The project could have been called “the balcony in all its forms" but instead it was named "the building that grows." The building "grows" thanks to plants on the building's walls. Its skin has become a kind of mini-ecosystem" (Ref. 1).
Vegetable barriers at the Port of Alicante
The Port of Alicante is finalizing the installation of a new environmental barrier at Pier 17, where bulk unloading is carried out, based on a water atomization method that allows dust particles to fall to the ground of the port area and not arrive by air to the city. (Ref 11) This initiative comprises activities to reduce pollution in the port, such as a vegetable barrier against the air pollution produced by the dust during the unloading of bulk materials, supplied by an irrigation system that recovers non-drinkable water from a nearby plant. It includes the extension of the Parque del Mar, to recover historical points for tourism and the funding of a research project on air pollution (Ref. 12). “This measure is integrated within the Plan of Urban Integration of the Port of Alicante, improving the landscape impact and the port-city boundary zones from the southern access of the urban environment, along with the “Parque del Mar”, to the west zone with the installation of vegetal screens in the inner zone of the port, contributing to an important particle retention and CO2 reduction.” (Ref. 1). Inside the park, which can be traversed through paths, there is a small ornamental lake with rockery and it has children's games and petanque courts, gymnastics courts and recreational areas. The green corridor has been created with the creation of artificial mounds, for which 65,000 cubic meters of earth have been necessary, which act as a vegetal screen and visually and acoustically isolate the port facilities of the city. (Ref 7)
Eco City Augustenborg
Ekostaden Augustenborg is the collective name for a program to aims to transform Augustenborg into a more socially, economically and environmentally sustainable neighborhood. Ekostaden Augustenborg is one of Sweden´s largest urban sustainability projects. Aims and implemented measures were based on the wishes of local stakeholders and residents: No more flooding, green roofs, a musical theme playground, an open stormwater system (ref. 1).
Let's help the bee in the city
BTC, a private company that has three shopping centres in Slovenia - one in Ljubljana - has engaged in supporting Carnolian Honey bees in Ljubljana through the "Let's help the bee in the city" project. As part of this, the company has placed beehives at the BTC shopping mall, primary school and distributed plants for people around Ljubljana to put on their balconies to support urban bees. In 2014, an urban apiary with four bee families was set up on the meadow behind the Atlantis waterfront, drawing attention to the importance of preserving Carniolan lavender and bees for the environment. They also take care of young people who are enthusiastic about urban beekeeping with the project. With the competition "Bee-friendly school", a nice teaching apiary was set up for primary school children in the area of the Medvode primary school. One of the urban beehives can also be visited by prior arrangement for organized groups. The project is still ongoing encouraging citizens to plant their balconies and window boxes with honey plants and by doing so provide the city bees with sufficient forage. (1, 2 and 6)
Green facade Vasakronan
Sweden's largest real estate company, Vasakronan, tests its first green outdoor facade at Kyrkogatan in Göteborg. The project was implemented with aim of improving the local climate and contributing to a more sustainable and resilient city. (Ref. 1)
Metrobosco Project
This is a pilot project part of the strategic plan "Città di Città" in the Milano province, launched in 2006 by the Direzione Centrale Risorse Ambientali, by the Parco Agricolo Sud Milano and by the Multiplicity.lab of the Politecnico di Milano. The project consists in the realisation of a green ring surrounding the city for an extension of 30.000 hectares (15% of the metropolitan area). The ring will connect a series of green areas already existing in the city. The project will insert a total of 3 million new trees along different areas of the city (2). The "metrobosco" is described as: a green belt made up of new forests, parks and rows that extend along the borders of the capital of Milan. A continuous ring of trees and small and large clearings to meet farms, abbeys, watercourses, agricultural areas and spaces for recreation and sports. The project arises from the need to redefine the relationship between city and country, to intensify plant and animal biodiversity, the preservation of existing and the construction of new "ecological corridors", the mitigation of climate imbalances, the abatement of noise and atmospheric pollution, the care and maintenance of the territory and the production of sources for agro-energies (4).
Green and Grand City
2017 Green and Grand City is part of Göteborg's 400th anniversary (in 2021), and plans are developed up to the anniversary on a yearly basis. In 2017, the focus was on a greener and grander Göteborg. The vision for 2021 includes three themes, water, building bridges (reduces divides between people) and open spaces. The anniversary efforts build on three elements of sustainability; social, ecological and economic. (Ref. 1)
