The Municipality of Valencia supports the City Observatory of Valencia’s green belt, which is implemented by a local association entitled “Per l’Horta”. The “Observatory project” aims at collecting data for the monitoring of the city green belt evolution. Once the data is collected by citizens, it is categorized and uploaded in a web-based platform accessible to all. Civil society groups are involved in the monitoring of the territory and enabled to better participate in the decision-making processes that affect their neighborhoods.
