Riconversione funzionale, verde urbano e gentrification: dalla Promenade Plantée di Parigi alla High Line di New York

This work aims at highlighting the role of urban open spaces in protecting biodi- versity, enhancing social relations as well as producing regeneration effects within the urban fabric. Moreover, the paper deals with two case studies about former railway lines in Paris and new York, recently transformed in elevated urban parks. in spite of being inserted in different urban and socio-economic structures, these newly-(re)built open spaces permit to evaluate which are the implications on patterns of consumption – both of places and goods – and whether they produce a “gentrification effect”.
