Water management (SDG 6)

“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)
