72% of the European population lives in cities and consumes about 75% of global energy and emits 80% of the greenhouse gases generated by their activity, contributing significantly to climate change.

The reintegration of nature and natural processes into areas built through nature and nature-based infrastructures (NBSs) are increasingly seen as a solution to land use challenges in cities.
NBSs can foster sustainable urbanization, restore degraded ecosystems, improve climate change adaptation and mitigation, and help risk management and resilience. Furthermore, by reshaping the urban environment, NBSs can improve inclusiveness, equity, and liveability, regenerating disadvantaged neighbourhoods, improving citizens' mental and physical health and quality of life, reducing violence and social tensions through a better social cohesion, especially for the most vulnerable groups i.e. children, the elderly and people with a low socio-economic status.

The Prato Urban Jungle approach is integrated into the guidelines for European cities for the implementation of urban forestry strategies and the use of Nature-Based Solutions and Plant-Based Solutions in architecture.
