Green urban infrastructure is not only perceived as trees, city parks, or forests. It can also include children’s playgrounds and even cemeteries. To assess the greenness of cities, it is not enough just to know the exact area of green spaces in the city. In principle, this assessment says nothing about the quality of those spaces, both ecologically and in terms of use. In addition to numbers representing the area or its percentage, there is a need for a spatial, quantitative, and qualitative assessment of the services provided to people by urban ecosystems.
