Infrastructural innovation

“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)

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)

A citizen initiative to transform a derelict urban area into a park. From 1987 the park's construction was left abandoned until in 1993 when over 80 citizen committees from the area organized themselves to start cleaning and reforestation activities in the park (ref 5,7). The sum of their efforts included reforestation, the creation of a community garden, and the redesign of watering systems for the park. (ref 5,6,7)

Pilestredet Park project was one of the largest urban ecology projects in Scandinavia and included redevelopment of a neglected inner-city quarter of Oslo while meeting high standards of sustainable construction. The project included energy efficient buildings with high quality indoor environments, plenty of green areas, as well as an extensive stormwater runoff management system for the whole site. Pilestredet Park also contributed toward the development of more sustainable construction techniques and products, much thanks to the strict requirements from the Environmental follow-up program developed by Statsbygg and Oslo Municipality's (Ref. 1)

“The Guadalquivir River offers some of the best landscape, ecological and environmental values. There is an exceptional variety of flora and fauna and the river is considered as one of the main lungs of the city and as a privileged area for the residents”. (Ref. 12) The river is an essential element of Cordoba, having been declared a natural monument in 2001. (Ref 3, p.4) There are ongoing efforts to maintain and restore the river as a natural and cultural heritage site (Ref. 1,2,5,8,9) and a space for recreational activities (Ref. 12).

Oslo municipality is underway with the large-scale project of opening up rivers that previously were running in underground pipes. Alna Environmental Park is a part of this project and includes major transformation and environmental upgrade of the river Alna. The Environmental Park runs along the river and has transformed grey structures to accessible parks and recreation areas and now acts as an important resource for Oslo's citizens. Central aims of the project are to improve the self-cleaning ability of Alna, while maintaining biodiversity in the region and to inspire future urban development. (Ref. 1, 3)

The park was designed to simulate a Mediterranean forest with 18 native species of Mediterranean flora. The water is being reused in order to avoid the depletion of aquifers (Ref. 1). Ecological vegetable gardens were created destined to community horticulture workshops organized by the city council (Ref. 2 and 3). The park was awarded a special prize in environmental Justice in 2010 by the Biodiversity Foundation through the "Life + European Capitals of Biodiversity"(Ref. 7 and 8), as a project that promotes environmental protection and social integration in the city. The inauguration of the park took place in 2007"(Ref. 1)

Hammarby Sjöstad is the first eco-city district in Stockholm. It is a 'town around a lake' where the planning work begun in the 1980s with an opportunity to expand the inner city of Stockholm. It is one of Stockholm's biggest urban development project and it focuses on water, energy and eco-friendly solutions. As a part of the ambition to create an eco-friendly city district, investments in e.g. green spaces, walkways and several large parks have been made. Furthermore, the Hammarby Model is the eco-cycle which describes environmental solutions used for energy, waste and water and sewage. It was established with a focus on 7 key areas: soil remediation, urban form, transportation, green buildings, energy, waste management, and water efficiency. (Ref. 1, 2, 11)

The area of Neuschönefeld where the park is located was built in the 1970s. With residents continuously leaving the area, housing fell vacant and the quality of the area decreased. Therefore, it was identified as a major regeneration area of Leipzig. The expansion and redevelopment of the Rabet park between Volkmarsdorf and Neustadt-Neuschönefeld was aimed at creating important impulses for leisure and recreation and develop a central “green switch” which contributes to sustainable urban development that also extends beyond the district (2, 3, 6).
