“…Generally, the soil sealing phenomenon is investigated using statistical data on a local basis (municipalities and provinces), aerial imagery (satellites images or ortho-photos), and LiDAR [27][28][29]. When using remote sensed images, different vegetation-based (Normalized Difference Vegetation Index-NDVI, Soil-Adjusted Vegetation Index-SAVI, Normal Difference Built-up Index-NDBI) and ecological urban indexes (Biotope Area Factor, BAF) are adopted to assess soil sealing [30][31][32].…”

“…Due to the spatially explicit component and the geographical scale of the soil sealing phenomenon, mapping and quantifying the amount of sealed surfaces is crucial [29]. Moreover, soil sealing monitoring through time is paramount to support decision making regarding sustainable territory planning and to assess the state of urban ecosystem services.…”

Biotope Area Factor: An Ecological Urban Index to Geovisualize Soil Sealing in Padua, Italy

Over the last few years, soil sealing has been recognized as one of the major threats in terms of soil degradation and loss of ecosystem services. Although many efforts have been promoted to increase the awareness of safeguarding soil for stakeholders, its value as a non-renewable resource as well as soil-related services in urban ecosystems is not implemented enough in urban planning and policies. Due to the spatially explicit component and the geographical scale of soil sealing, mapping and quantifying the number of sealed surfaces is crucial. The aim of this paper was to estimate and geovisualize the soil sealed in the city of Padua (Italy) at a very detailed scale, testing the use of the Biotope Area Factor (BAF) index. Moreover, the paper aimed to simulate an alternative mitigation scenario in a specific study area of the city. Spatial analysis was performed testing the BAF index in a Geographic Information Sistem (GIS) environment and using aerial ortho-photos at very high resolution. The results show different values of the BAF index for all four neighborhoods from 0.35 to 0.69. In the mitigation scenario, the value of the BAF index was improved using a measure of green roofs. In conclusion, the paper provides an insightful case study for enriching the debate about soil sealing and gives scientific support for sustainable urban planning.

“…There is a rising demand for residential space per capita, an increase in numbers of inhabitants due to migration, as well as the designation of industrial and commercial areas in the open space, sometimes despite existing urban fallow and converted areas, not only in Germany [9,10,11]. The progressive urbanisation at the expense of the open space, negative changes in urban climate, and the adaptation to a changing climate require the protection and development of both inner-city and peripheral green spaces as balancing spaces to ensure ecosystem services that are essential for the health and safety of its inhabitants [12,13,14,15].…”

This paper addresses the question of how a sustainable urban development can be supported through simple measured quantities in the context of the specific provision of green space and open space. The specific provision of green space is analysed based on a combination of six indicators that describe, on the one hand, the access of inhabitants to green spaces and on the other hand, the settlement character as well as the strong anthropogenic imprint on the urban landscape. The indicators were calculated and combined in a 9-cell matrix for classifying the areas studied. The implementation was carried out at two scales for all German cities with at least 50,000 inhabitants as well as exemplarily for city districts of eight big cities. The calculated indicator values for representing green characteristics decrease with increasing number of inhabitants, whereas the opposite relationship was obtained for the indicators of the grey characteristics. We show how the approach provides an in-depth morphological assessment of German cities ranking their scores from low to the high presence of grey/green characteristics.

“…Although the results of Urban Atlas and CORINE datasets showed slight disagreement, it has been discovered that Tallinn has the highest share of greenery, Vilnius is in the middle and Riga is the last. Analysis of 1990, 2000, 2006and 2012 showed the highest relative decrease of greenery in Riga (2.53 %) over time, Tallinn was the second (1.44 %) and the smallest decrease (0.53 %) was in Vilnius. The analysis of degree of soil sealing demonstrated the highest relative share of pervious surfaces in Tallinn (95.5 %) and the smallest share in Vilnius (92.1 %), therefore this research nominates Tallinn as the greenest (literally) capital of the Baltic States.…”

The meaning of the term “green city” today is more related to sustainability rather than to vegetation or greenery. Therefore, the aim of this research is not to develop another complex green index, but simply to calculate and compare a share of greenery among functional urban areas of three Baltic capitals. Comparison was done using GIS tools and analysing Urban Atlas, CORINE and degree of soil sealing datasets. Although the results of Urban Atlas and CORINE datasets showed slight disagreement, it has been discovered that Tallinn has the highest share of greenery, Vilnius is in the middle and Riga is the last. Analysis of 1990, 2000, 2006 and 2012 CORINE datasets showed the highest relative decrease of greenery in Riga (2.53 %) over time, Tallinn was the second (1.44 %) and the smallest decrease (0.53 %) was in Vilnius. The analysis of degree of soil sealing demonstrated the highest relative share of pervious surfaces in Tallinn (95.5 %) and the smallest share in Vilnius (92.1 %), therefore this research nominates Tallinn as the greenest (literally) capital of the Baltic States.
