Book Part Citation - Scopus: 6Insights for the Enhancement of Urban Biodiversity Using Nature-Based Solutions: the Role of Urban Spaces in Green Infrastructures Design(Springer, 2022) Ronchi, Silvia; Salata, StefanoNature-Based Solutions (NBS) increase their efficacy if included in an overall framework such as Green Infrastructures (GI), maximising ecosystem benefits and avoiding possible negative externalities and trade-offs. Urban green spaces and NBS are components of GI that increase the quality of urban settings, enhancing territorial resilience, and improving the health and well-being of citizens. The research proposes a methodology, tested in the municipality of Settimo Torinese (North-west of Italy), for selecting urban green spaces with high performance in terms of biodiversity conservation, which can involve a GI strategy as a multifunctional structure that combines different Ecosystem Services (ES). The enhancement of natural capital and ES provision is reached identifying suitable NBS to protect and improve biodiversity based on the Habitat Quality (HQ) assessment, considered a key supporting service. HQ was derived testing two different sensitivity data: the first based on Land Use/Land Cover, while the second uses the Normalised Difference Vegetation Index. The latter was functional to overcome limits in representing the ecologic integrity of urban areas highlighting an important variety of green spaces and related ES, especially in compact cities. The results are useful for defining effective environmental policies and strategies in urban areas and addressing the decision-making process towards sustainable development goals. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.Article Citation - WoS: 16Citation - Scopus: 17Integrating Ecosystem Vulnerability in the Environmental Regulation Plan of Izmir (turkey)-What Are the Limits and Potentialities?(MDPI, 2022) Salata, Stefano; Özkavaf Şenalp, Sıla; Velibeyoğlu, KorayThe land-use regulatory framework in Turkey is composed of several hierarchical plans. The Environmental Regulation Plan pursues comprehensive planning management, which ranges between 1/100,000 and 1/25,000 and defines the framework for local master plans. Unfortunately, there is scarce knowledge of how these plans effectively protect the environment. Besides, these plans have poor consideration of socio-economic dynamics and the ecosystem vulnerability, while evaluating the actual conflicts or synergies within the localization of ecological conservation and settlement expansion areas. In this work, an ecosystem-based geodatabase was created for the western Izmir area (Turkey). The dataset has been created by employing a supervised classification sampling of Sentinel-2 images acquired on 28 March 2021, while accessing ONDA-DIAS services to L2C products. Then, the InVEST software was used to map the Habitat Quality and the Habitat Decay, while the ArcMap raster analysis tool was employed to generate the Normalized Difference Vegetation Index. The results were used to classify the ecosystem vulnerability of the western metropolitan area of Izmir and then superimposed to the Environmental Regulation Plan of the city of Izmir (2021), thus evaluating synergies and conflicts. Although integration of the ecosystem services approach into spatial planning is lacking in the planning practice of Turkey, the paper provides an operative methodology to integrate ecosystem evaluation in environmental planning as a basic strategy to support sustainable development.Book Part Designing Healthier Cities. an Empirical Study of the Ecosystem Functioning and Mortality in the Districts of Turin (italy)(Springer, 2022) Salata, StefanoThe twenty-first century is called “the age of the metropolises and cities” as they become the predominant living environments of human beings. Nonetheless, metropolitan areas are more vulnerable, for their intrinsic nature is dense and interconnected. The experience from the COVID-19 crisis teaches us how an epidemic outburst has been generated by reducing habitat at the planetary scale, and how the quality of the environment even affects the diffusion of the virus. But what is the relation between Health and Nature in urban areas? Is this relation so evident? Within this study, a preliminary assessment of the relations between urban environment and health will be evaluated by modelling the spatial distribution of the Habitat Quality in Turin and the mortality rates in the same areas. Data will be gathered at their maximum spatial precision, thus obtaining a reliable map of the distribution between the two indicators at the district level. Habitat Quality will be composed by the value of the supporting biophysical function and anthropic threats. Health will be evaluated using the death number in the statistical units and the accessibility of citizens to green areas. An overall assessment will be finally presented considering the simultaneous evaluation of spatial clusters and delineating how conservation and valorization measures can benefit from a site-specific evaluation of Ecosystem Services, while revealing their effects on human health.Article Citation - WoS: 12Citation - Scopus: 15Designing With Ecosystem Modelling: the Sponge District Application in İzmir, Turkey(MDPI, 2022) Salata, Stefano; Arslan, BertanClimate change is threatening coastal cities affected by multiple hazards worldwide. Due to the increase in extreme weather events and the low capacity of cities to adapt to these odds, losses, exposure, and fatalities arise with the occurred events. Besides, traditional hazard mapping and risk planning techniques often fall behind when facing a climate crisis since extreme changes in quantity, frequency, and distribution of meteorological phenomena are observed. Specific and localized flood vulnerability mitigation strategies need to be developed, particularly for settlements on coastal and sloppy areas with a high risk of stream accumulation during rainfall days. This paper uses the urban flood risk mitigation of Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) generated within the Natural Capital Project to determine İzmir’s cloudburst vulnerability level. The city has experienced several cloudbursts in the last couple of months which inundated densely populated areas. The soil’s hydrologic conductibility and the land use/land cover (LULC) map were required as main inputs. The LULC map was produced on the basis of surface imperviousness. The model calculates the run-off volume and how much is retained by soil and vegetation. Outputs were used to concretely apply the sponge district concept while designing performance-based ecosystem solutions. In the light of the findings, the new performance-based design demonstrated how digital ecosystem modelling could support the urban design decision-making process.Article Citation - WoS: 16Citation - Scopus: 17Land Suitability Analysis for Vineyard Cultivation in the Izmir Metropolitan Area(MDPI, 2022) Salata, Stefano; Özkavaf Şenalp, Sıla; Velibeyoğlu, Koray; Elburz, ZeynepThe grapevine, so-called Vitis vinifera L., is one of the most diffuse perennial crop plan-tations in the world due to a flourishing market that shaped the landscape and the societal val-ues. Turkey has been a historical vine producer, counting on an overall vineyard extension of 550,000 hectares. Besides, Turkey has some favorable pre-requisites to be one of the most fertile lands for vineyard production: variegated topography, rich soil diversity, heterogeneous morphology, and several micro-climatic conditions. However, establishing a flourishing and fully productive vineyard requires many years, and therefore, the selection and management of sites should be considered with great attention. Within this work, a first land suitability analysis for vineyard production has been established for the entire metropolitan area of Izmir according to the most scientifically-agreed criteria: elevation, slope, aspect, land capability, and solar radiation. These criteria were superim-posed through spatial overlay analysis using Esri ArcGIS (ver.10.8) and evaluated using the Principal Component Analysis technique. The first three bands were then extracted to define the most suitable areas for vineyard production in Izmir. The final layer has been used to define which areas can be considered for future strategic expansion and management. The discussion focuses on the Kozak plateau, where a new policy of vineyard plantation will be promoted with techniques that aim to maintain and revalorize the traditional vineyard landscapes and conserve traditional methods and practices that have evolved with the cultural values of the villagers and producers.Article Citation - WoS: 23Citation - Scopus: 25Performance-Based Planning To Reduce Flooding Vulnerability Insights From the Case of Turin (north-Wwest Italy)(MDPI, 2021) Salata, Stefano; Ronchi, Silvia; Giaimo, Carolina; Arcidiacono, Andrea; Pantaloni, Giulio GabrieleClimate change impacts urban areas with greater frequency and exposes continental cities located on floodplains to extreme cloudbursts events. This scenario requires developing specific flooding vulnerability mitigation strategies that improve local knowledge of flood-prone areas at the urban scale and supersede the traditional hazard approach based on the classification of riverine buffers. Moreover, decision-makers need to adopt performance-based strategies for contrasting climate changes and increasing the resilience of the system. This research develops the recent Flooding Risk Mitigation model of InVEST (Integrated Evaluation of Ecosystem Services and Trade-off), where cloudburst vulnerability results from the soil's hydrological conductivity. It is based on the assumption that during cloudburst events, all saturated soils have the potential for flooding, regardless of the distance to rivers or channels, causing damage and, in the worst cases, victims. The model's output gives the run-off retention index evaluated in the catchment area of Turin (Italy) and its neighborhoods. We evaluated the outcome to gain specific insight into potential land use adaptation strategies. The index is the first experimental biophysical assessment developed in this area, and it could prove useful in the revision process of the general town plan underway.Article Citation - WoS: 48Citation - Scopus: 56A Spatial Evaluation of Multifunctional Ecosystem Service Networks Using Principal Component Analysis: A Case of Study in Turin, Italy(Elsevier, 2021) Salata, Stefano; Grillenzoni, CarloThe multifunctional Ecosystem Service supply analysis at the spatial level is often the output of a weighted sum of layers in a Geographic Information System (GIS). This procedure is weak in detecting and representing the relationships between the input layers. Nonetheless, composite indicators produced by overlaying techniques are quite common in applied research and their discrepancies are underestimated in the scientific community, thus affecting the quality of resulting composite maps. In this work, we empirically test the effectiveness of multivariate statistics to obtain reliable composite Ecosystem Maps in the Turin metropolitan area (north-west Italy). We apply the Principal Component Analysis (PCA, using Matlab and ESRI ArcGis) to seven Ecosystem Service models (Habitat Quality, Carbon Sequestration, Water Yield, Nutrient Retention, Sediment Retention, Crop Production and Crop Pollination) and we evaluate how much the resulting composite map differs from the traditional GIS overlay. In doing this, the spectral analysis (with eigenvectors and eigenvalues) of the covariance matrix of the normalized layers confirms the heuristic arguments about the dependence between Ecosystem Services. We show that the PCA method can provide valuable results in landscape Green Network design, avoiding the limits of standard overlaying procedures. Finally, smoothing and classification techniques, applied to PCA estimates, can further improve the approach and encourage its use in various ecological indicators.
