Durabilité, urbanité et mixité dans les opérations d’intérêt national (OIN) : les exemples d’Euroméditerranée (Marseille) et de l’Écovallée Plaine du Var (Nice)

Thanks to a certain number of field studies and surveys carried out in Marseille and Nice, within the OIN Euroméditerranée and Écovallée Plaine du Var, we will question their reality and their different territorial impacts.
