Revitalization of Rakova Jelša
Revitalization of Rakova Jelša includes cleaning of the informal waste area and renovating it in a park which connects the city with the Marsh Landscape Park. In two phases, the park area was arranged together with the children's playground and the footbridge over Lahov graben. The possibility of regulated urban self-sufficient agriculture or gardens in the immediate vicinity of the city center means the added value of this area. (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).
Planting native trees along the highway
In 2010, about 300 people participated in the planting program for the “350” project and under the “Verde por el Clima” program (Green for the climate) organized by the Department of Environment, Cordoba city council (Concejalía de Medio Ambiente). (Ref. 3)
Alna Environmental Park
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)
