Abstract
The implementation of nature-based solutions and green infrastructure are essential strategies to cope with the current climate crisis in urban and peri-urban environment. However, within local urban agendas, policymakers and stakeholders mainly consider municipal green areas, without including those owned by other public or private actors. A key role is played by the heritage of universities, which is characterized by large vegetated systems. However, this potential is often underestimated and under-investigated in many cities. The study aims to investigate the potential of existing green areas in the University of Padua. The specific objectives aim to: i) quantify and map university herbaceous and arboreal greenery, ii) evaluate the carbon storage and sequestration ecosystem service in two representative study areas, iii) assess how university greenery can integrate the sustainable strategies of the Municipality of Padova. The methodology was developed in GIS environment, and it was organized in several complementary steps, by using orthophotos and participatory field surveys. The results showed a total of more than 2 km2 belonging to or used by the University in the Veneto Region: 27% (535,891 m2) are green areas, of which 15% are arboreal while 12% are herbaceous. If the agricultural areas are included, the overall result grows to 65%. The second result focused on the analysis of carbon storage and sequestration ecosystem service in two representative study areas of the University, and it was later related to the carbon footprint of equivalent average CO2 emissions of a university student. The comparison showed how the contribution of these green areas is currently limited for climate change mitigation. Instead, thanks to the location of these spaces within the city of Padua, the results show their potential contribution to climate change adaptation, such as climate shelters during heat waves, by implementing synergy policies with the local administration.
L’implementazione delle cosiddette nature-based solutions e delle infrastrutture verdi rappresentano elementi necessari per far fronte all’attuale crisi eco-climatica in ambiente urbano e periurbano. Tuttavia, nell’ambito delle agende urbane locali, decisori politici e stakeholders considerano principalmente le aree verdi comunali, senza includere quelle di proprietà di altri attori pubblici o privati. Un ruolo chiave, spesso sottovalutato e poco investigato in numerose città, è svolto dal patrimonio delle università, caratterizzato da importanti sistemi vegetati arborei, arbustivi ed erbacei. Questo studio mira ad indagare le potenzialità delle aree verdi già esistenti nell’Università di Padova. Gli obiettivi specifici mirano a: i) quantificare e mappare il verde erbaceo e arboreo universitario, ii) valutare alcuni servizi ecosistemici da esso forniti in due aree studio rappresentative, iii) valutare come il verde universitario possa integrare le soluzioni sostenibili del Comune di Padova. La metodologia è stata sviluppata in ambiente GIS ed è stata strutturata in diverse fasi complementari tra loro, mediante l’uso di ortofoto e di rilievi partecipati sul campo. I risultati hanno mostrato che, su un totale di oltre 2 km2 di superficie appartenente o utilizzata dall’Università nella Regione del Veneto, il 27% (535.891 m2) sono aree verdi, di cui il 15% è arboreo/arbustivo mentre il 12% erbaceo. Si raggiunge il 65% del totale se vengono incluse anche le aree agricole. L’analisi dello stoccaggio e del sequestro di carbonio in due aree studio rappresentative dell’Università ha mostrato che, comparando questi valori con la carbon footprint delle emissioni di CO2 equivalente media per uno studente universitario, il contributo ai fini della mitigazione al cambiamento climatico delle aree verdi sia attualmente non rilevante. Data la localizzazione di questi spazi all’interno della città di Padova, i risultati mostrano invece il loro potenziale contributo in un’ottica di adattamento al cambiamento climatico, come ad esempio “rifugi climatici” durante le ondate di calore, attuando politiche di sinergia con le amministrazioni locali.
