As part of the Adopt-A-City initiative of the Municipality of Athens, companies can adopt a site in the city area. Often, these are places that have been abandoned for many years and are filled with rubbish. With the financial support of the companies, these sites are then transformed into small parks and squares. The initiative employs nature-based solutions and ecosystem restoration, as many of the parks and squares are upgraded through the planting of trees and many other types of plants. Next to increasing the value of the city's green infrastructure, these so-called pocket parks shall also help to reinvigorate urban areas and reorganize the urban and social fabric at a neighborhood level.
