The research topic develops through two integrated targets (T1,T2).T1 aims at developing a method to identify a regional, multifunctional green infrastructure (GI), where multiple ecosystem services (ESs) are delivered by a network of natural and seminatural areas, with a view to providing recommendations to improve regional GIs. A set of ES-based criteria for mapping the suitability of green spaces to be included within a GI will be identified and modeled, while the connectivity will be spatially analyzed through ecological corridor modeling. By overlaying the layouts of GIs and ecological corridors, the suitability of ecological corridors to be part of a GI can be assessed, and environmental analysis of its features can be performed, thus highlighting strengths and weaknesses on which a set of actions to improve the environmental quality of the GI can be grounded.T2 aims at developing an approach to identify a local GI through nature-based solutions (NBSs), aimed at integrating GIs within urban planning, as urban GIs also include NBSs, such as green roofs or rain gardens. After an analysis of best practices, a taxonomy of NBSs that support ES supply will be defined, together with a quali-quantitative evaluation framework allowing for the evaluation of ESs delivered by local GIs and for developing a method to be included in planning processes and tools at the metropolitan and urban scales.Sardinia and its towns will be taken as a case study for T1 and T2, respectively.

The ideal candidates will have:- A background in spatial planning, obtained through a Master’s degree in environmental engineering, urban and territorial planning, architecture, or closely related field.- Skills in quantitative analyses and Geographic Information Science (GIS) techniques.- Interest in collaborative and interdisciplinary work.- Willingness to advance their knowledge and skills, both independently and in a supervised manner.- Good command of both written and spoken English.

The doctoral student will work within a research team specialized on sustainable spatial planning based at DICAAR, University of Cagliari. Besides the proponent, the team comprises Dr. C. Zoppi (Professor), Dr. F. Leone (Assistant professor, RTDA), two post-docs, two doctoral students. The team, well recognized for its specialization and scholarly publications, works on many collaborative projects and has long-term national and international networks. It is an excellent learning environment for early-stage researchers, who can enjoy hands-on training and unique mentoring opportunities, frequent meetings and seminars.Cutting-edge research facilities are available through the Department.
