Associare i territori della biodiversità al contesto urbano potrebbe risultare un’azione ossimorica. Eppure, affrontando la questione dell’incrementale perdita di biodiversità che i nostri ecosistemi stanno vivendo, le città assumono un ruolo fondamentale sia in termini di causalità che di possibile rimedio. Per la sua complessità, la tematica richiede all’urbanistica di operare attraverso un approccio multi disciplinare e multi scalare, per integrare saperi e competenze al fine di produrre politiche efficaci che abbiano risultati concreti per la coesistenza tra città e natura. Con tali presupposti, il Centro Nazionale per la Biodiversità (NBFC) promuove un’attività di ricerca per un approccio sostenibile alla biodiversità, lavorando sinergicamente al monitoraggio, alla conservazione, al ripristino e alla valorizzazione di essa. Tradurre queste macro-attività di ricerca nel contesto urbano richiede innanzitutto una ricognizione dello stato di fatto su questo tema. Osservando le aree metropolitane italiane, le politiche urbane che si occupano esplicitamente di biodiversità sono scarse. Lo studio del territorio nazionale ha comunque permesso di evidenziare alcune azioni chiave che le politiche pubbliche stanno mettendo in pratica per tutelare e incrementare la biodiversità urbana, a diverse scale temporali e spaziali. Tra queste azioni si ritrovano la forestazione urbana, il riconoscimento e il ripristino della biodiversità e il contenimento del consumo di suolo. Il contributo riflette sul rapporto tra queste macro-azioni e la loro effettiva ricaduta, attraverso l’analisi e lo studio di esempi significativi.

Abstract
Associating biodiversity-rich territories with the urban environment might appear paradoxical. Yet, in addressing the progressive loss of biodiversity affecting our ecosystems, cities play a fundamental role, both as contributors to the problem and as potential sources of solutions. Given the complexity of this issue, urban planning must adopt a multidisciplinary and multiscalar approach, integrating different fields of knowledge and expertise to develop effective policies capable of delivering tangible results for the coexistence of cities and nature. Against this background, the National Biodiversity Future Center (NBFC) promotes research aimed at developing a sustainable approach to biodiversity through coordinated activities focusing on its monitoring, conservation, restoration, and enhancement. Translating these broad research objectives into the urban context requires, first and foremost, an assessment of the current situation. An examination of Italian metropolitan areas reveals that urban policies explicitly addressing biodiversity remain relatively limited. Nevertheless, an analysis of the national territory has made it possible to identify several key measures being implemented through public policies to protect and enhance urban biodiversity across different spatial and temporal scales. These measures include urban afforestation, the identification and restoration of biodiversity, and the reduction of land take. The paper critically examines the relationship between these broad areas of intervention and their actual impacts, drawing on the analysis of significant case studies to assess their contribution to the protection and enhancement of biodiversity in urban environments.| File | Dimensione | Formato | |
