As part of the Territorial Agenda 2030 pilot, the municipality of Trento (IT) commits to greening the city through a large urban reforestation initiative of a specific brownfield on (public) land. This will be done in collaboration with socially disadvantaged young people and senior citizenry. A start-up of young people will communicate on the value of ecosystem services and take over its mapping. In the long-term the project shall give insight into climate adequate tree species and connect to the local Green Plan.
