Conceptions of Urban Greening and the Management of Heritage Assets. The ‘Green School Plan’ for the Florence UNESCO Area

The chapter is dealing with Urban Greening, (UG) through natured based systems (NbS) in sensitive historic environmentsthat should be considered as ‘a network of multi-functional green spaces which can deliver environmental benefits and improve health and well-being for community. The promotion of greening actions can work as a key bridging concept between cultural heritage and nature. They have been also used extensively to address issues of urban risks such as flooding, climate change, biodiversity loss. One of the key benefits of an UG approach is the ability to be adaptive to the spatial design of a site. This flexibility and adaptability of urban greening is crucial to shape historic environments and landscapes in a more responsive way. In this reflective and adaptive way UG can be best linked to urban design. The chapter tries to bridge the gaps through innovative urban planning and design to manage the well-defined by UNESCO "Historic Urban Landscapes", (HULs).
