Land Surface Temperature and Urban Policies: The Ferrara City Case Study

Today's global challenges are increasingly complex, and forecast scenarios show a general increase in risks that could compromise human permanence in some areas of the planet. In this context, cities have a key role, both because they concentrate an increasing number of inhabitants and because they will be among the first areas to feel these effects. As pointed out by the IPCC, addressing these challenges requires a redefinition of the organization of urban spaces by assigning, more or less explicitly, a key role to spatial planning. Urban and territorial planning may be the main tool in the regulation of transformation processes. Planning has a crucial role, especially if territorial transformations are no longer mainly linked to expansive logics. In this case, it is possible to orient urban choices and policies towards a sustainable use of resources, including land resources that continue to be overexploited. Starting from these assumptions, the present work intends to analyze the relationship between the LST (Land Surface Temperature) extracted from the data provided by MODIS (Moderate-resolution Imaging Spectroradiometer) and the level of soil sealing within the municipality of Ferrara in northern Italy. The reference period is between 2015 and 2021. The objective is dual. The first is investigating how the environmental matrix can influence the temperature values detected; the second is investigating how the implementation of transformative forecasts provided by the urban planning tool in force, could influence the thermal comfort of the study area.
