Pioneer Case

Lichens indicators

A short description of the NBS project

Creation of a air quality map from the taxonomical diversity and the geographical distribution of lichens by using a lichen index. Lichens are sensitive to pollution and therefore can serve as air quality indicators. The objective of the action is to use lichens as air quality bio-indicators to create an air quality map of Bordeaux.

Business Model
Class Type Description
TechnologicalSubstitute with renewables and natural processesThis project is based on lichens' ecology understanding in order to assess the air quality of a city.
Temporal Factor
Expected time for the NBS to be fully effective after its implementation short (immediately to few months)
Expected life time of the intervention around 10 years
