It promotes beekeeping and sustainable production and consumption patterns, and the honey is a brand product of the University [1,3,4].

The Reconstruction of the Southern Bank of Schütt Island is the starting point of the regeneration of the Old City of Nurnberg. Within the project, the access to water and recreational functions of the river banks were improved. (1) The project was completed on an 1800 square meter large area, which includes open meadow areas, a 170-meter-long bank terrace, trees, and benches.

The city of Wuppertal participates as a model region in the joint research project SAMUWA which aims at developing planning instruments which combine urban drainage with urban and open space development measures. With regards to the work package C.1: open space design strategies for a water sensitive city, one focus area and proposed measure, namely the "Varresbecker" flood channel is of special interest since it has been subject to comprehensive implementation plans in Wuppertal so that its implementation can be expected in the next years (Ref. 1, 2, 4 and 5). Alongside the water channel, a recreational area will be created with information to raise awareness about water management issues and climate change. (Ref. 2)

The Podlasie Opera and Philharmonic – European Art Centre in Białystok ("green opera") in Białystok, is known for its green roofs, green walls and extensive gardens, which perfectly harmonize with the surroundings. The green area serves as a platform for cultural events and successfully promotes the city. Opera gardens are divided into several levels with lawns, walking paths, bridges, sculptures, and small ponds. Different green elements of the building reduce heat effect and noise, increase the thermal insulation of the building, improve local biodiversity and limit rain drainage to the city centre [1].

In 2014, students, instructors and representatives of an appropriate company built a "small green roof" on the balcony above the entrance to the Department of Architecture at the Bialystok University of Technology. The initiative was a part of the "Green City by nature" project - a nationwide educational campaign about nature-based urban solutions. It took only 5 hours to unfold the roll of grass and prepare the ground for all year thuja and vines [1,2].

Weaver Square Community Garden started in May 2011 on a derelict site owned by Dublin City Council. The site contains the Community Garden and 28 individual allotments let out by the council. The main focus of the Community Garden is to create a safe and relaxing green space for all to use and enjoy. The organizers hope in the future to have more emphasis on the garden as a learning experience, with open days & workshops and other related talks. Dublin City Council has given notice that Weaver Square Community Garden and 27 family allotments are to close at the end of 2018. (Ref. 1; Ref. 2; Ref. 3)

As part of a larger project, this project aimed at creating a vertical garden in the Levante Square, in the Deustro neighborhood, the city of Bilbao. The intervention was initiated by the Bilbao's municipality in 2016 and aimed at creating a green area that was a bit unconventional and artistic at the same time. The landscape design incorporates local elements such as the trawlers, the cliffs of the Cantabrian coast and the local architecture, integrating nature and tradition (Ref 1).

Abandoibarra is an area of ​​the town of Bilbao, next to the Bilbao estuary, sizing ​​348,500 square meters. Abandoibarra has been the industrial zone of Bilbao, where shipyards and other companies related to the industrial sector were located. Building upon the 1997 master plan completed by Balmori Associates, Pelli Clarke Pelli Architects and Aguinaga y Asociados, the area has been reinvented as an international cultural district and tourist destination. Two-thirds of the 30-hectare site is dedicated to parks and open spaces, creating a public oasis and grounds for a suite of buildings by master architects (Ref 1,2).

The company running the Zabalgarbi waste disposal site manages a solid waste–to-energy plant and also houses a mechanical biological treatment (MBT) plant, a composting plant, a landfill and a leachate treatment plant. During construction of the first plant, Zabalgarbi regenerated and recovered the entire Artigas-Arraiz area covering 108 hectares. The area was degraded by shaft mining activity and an opencast quarry. The project aimed at the reforestation and landslide mitigation of this degraded area. Today the area has been reforested, trails were built and space provided for people to enjoy themselves in gardens, picnic areas and along forest tracks. (Ref 1)

Zorrotzaurre is an artificial peninsula located within the Deusto district of Bilbao, Spain. It was formed during the 1950s and the 1960s, when a canal was built to facilitate navigation in the estuary of Bilbao. The Zorrotzaurre project is the latest major urban renewal project to commence in Bilbao. It is an integral and sustainable plan that recuperates a currently derelict site to convert it into a new quarter, and which also includes a flood protection system with water tanks to retain water and a flood protection barrier (Ref 1)
