“…The values of functioning also ranged from 0 to 10, with 0 indicating non-functional sites highly influenced by humans and 10 pointing to the complete preservation of natural hydro-geomorphological features and processes. Further details on these two indexes are provided in previous work [33].…”

Planning a well-structured urban green infrastructure (UGI) is essential for cities to counteract the impacts of climate change. Soil carbon and air temperature differences between open and plant-covered sites were used as proxies of carbon sequestration (CS) and temperature regulation (TR) to evaluate the current conditions of UGI in Zaragoza, a medium-sized city in northeastern Spain. Alternative scenarios were constructed, after a stakeholder consultation, at both city and municipal (city plus peri-urban zone) scales, extrapolating the highest values of CS and TR to two groups of UGI types grouped based on the state of their ecological functioning. We employed analysis of variance to compare mean values of CS and TR across diverse scenarios at both city and municipality scales. Statistically significant differences were found in city-scale and municipality-scale scenarios for both CS and TR. Multiplying CS by area did not show significant variation in city scale. Significant differences were found when multiplying TR by area at both scales, with exceptions in certain scenario combinations. These results suggest favoring the restoration of UGI sites in peri-urban zones (such as forests and steppe zones) to increase CS and those in densely urbanized zones (such as urban parks) to provide TR benefits.

“…Additionally, the LU/LC map does not differentiate between the different types of UGI in the city. Therefore, we had to use the data of UGI sites that were studied by [33], which evaluated UGIs in Zaragoza. Furthermore, our approach focused primarily on the ESs of TR and CS.…”

Urban green infrastructure (UGI) can provide key ecosystem services (ES) for human well-being. For this purpose, it is critical to ascertain which characteristics regulate the provision of ES by UGI. In this study, eight ES (water supply, water regulation, waste regulation, nutrient regulation, soil formation, carbon sequestration, air temperature regulation and air humidity regulation) of thirty UGI sites of Zaragoza (Spain), were evaluated using proxy indicators derived from analyzed soil samples, and in-situ measured air temperature and humidity. A principal component analysis was performed to group different ES, and to study the dispersion of different types of UGI along the distinct ES. Additionally, relationships, between the evaluated ES and predictors; flatness, imperviousness, regularity, naturalness and functioning of the UGI sites were studied through linear and quadratic regressions. Large UGI sites such as riparian zones, meanders and natural forests showed relatively high values of ES in contrast with more artificial sites. Moreover, the study showed that water supply, water regulation, soil formation, carbon sequestration and air temperature regulation were significantly and positively related to ecological naturalness and functioning, while imperviousness was the main predictor explaining the reduction of five ES. Our findings provide evidence for the existence of important interactions between predictor variables and ES in UGI. It also showed that the provision of urban ES can be improved expanding the variety and type of green infrastructure sites, decreasing impervious area, and increasing the naturalness and functioning of UGI.
