Abstract The Fifth Session of the UNEA-5 defines Nature-based Solutions (NbS) as “actions to protect, conserve, restore, sustainably use and manage natural or modified terrestrial, freshwater, coastal and marine ecosystems, which address social, economic and environmental challenges effectively and adaptively, while simultaneously providing human well-being, ecosystem services and resilience and biodiversity benefits”. A large number of the EU HORIZON 2020 research program projects include the implementation of NbS in urban settings. The proGIreg project implemented several NbS for urban regeneration with and for citizens in its Living Lab in the city of Turin (Italy), among others. Focusing on the NbS of urban forestry, this paper addresses the following question: where can NbS be implemented within the city, in order to maximize their social impact? To achieve this goal, by identifying neighborhoods in need of NbS implementation, the 3–30-300 rule proposed by the International Union for Conservation of Nature (IUCN) was adopted and implemented, taking greater account of environmental and social characteristics. The paper also proposes an index to identify neighborhoods of the city that could have precedence in the implementation of NbS. The results highlight 10 neighborhoods where there is a high need of NbS implementation.

Highlights • Nature-based Solutions (NBS) can contribute significantly in adapting urban environments to climate change. • Where to localize the implementation of NBS in cities is a highly political process, which requires a critical perspective. • A multidimensional and multiscalar context-based approach is required in identifying areas that need precedence in NbS implementation.
