How sustainable is a tree on a roof?


Urban trees provide a lot of positive things in urban environments: they increase the biodiversity; clear the air up by fixing solid particles in suspension and CO2 and releasing O2; retain the ground and prevent the erosion of soils; and protect the pedestrians from the wind and sun. They are also a meeting point: people have traditionally met under a tree to talk, discuss, legislate, judge or trade. A popular recent trend is including trees in buildings as a way to make them more sustainable. Even on roofs. But, how sustainable is a tree on a roof?

The limit of a city is a cultural and social construction: the city tends to grow over the agricultural land, but in western cities this process is not because of the need for housing but an economic process that transforms the lands into a consumer good. This agricultural land lacks a special protection but in return it provides food and resources to the society, and it’s part of the cities’ success. Is it possible to harmonize the urban growth and the preservation of the agricultural land?
