    Integrating Ecosystem Vulnerability in the Environmental Regulation Plan of Izmir (turkey)-What Are the Limits and Potentialities?
    (MDPI, 2022) Salata, Stefano; Özkavaf Şenalp, Sıla; Velibeyoğlu, Koray
    The 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.

    Designing Healthier Cities. an Empirical Study of the Ecosystem Functioning and Mortality in the Districts of Turin (italy)
    (Springer, 2022) Salata, Stefano
    The 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.

    A Spatial Evaluation of Multifunctional Ecosystem Service Networks Using Principal Component Analysis: A Case of Study in Turin, Italy
    (Elsevier, 2021) Salata, Stefano; Grillenzoni, Carlo
    The 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.
