Improved soil quality

The project opts for switching to more sustainable and organic ways of handling natural parks in the urban areas of the city of Bologna. The project was launched in 2008 and focused on 100 hectares, meaning 10 parks (out of the 1.100 total in the city). The goal is to develop maintenance techniques with low impact on local flora and fauna, stimulating biodiversity and an equilibrium with the surrounding urban environment, as well as the reduction of toxicity impacts for vulnerable residents (i.e. children and elderly people) (1 and 2).
This NBS solution focuses on changing maintenance of Bologna public urban parks from conventional techniques to biological ones (1 and 2).
