In recent years, natural areas have been exposed to increasing anthropogenic pressure related to the growing need for natural resources. Comprehensive information on the geodiversity of a territory is essential for all stakeholders in order to define effective land management toolsusefull for preserving the natural heritage for future generations. We computed geodiversity map as the summary of lithological, morphological, paedological indicators and hydrological index using a workflow based on the grid analysis, performed in a Geographic Information System environment. The geodiversity map of Italy (main map) provides a synoptic view of the geographical distribution of the abiotic component of the landscape ranked into five classes varying from very high to very low geodiversity. This map is supplemented by histograms showing the percentages of geodiversity classes for each Italian region and a Regional Geodiversity Index map that assigns a geodiversity value to each Italian region.

The amount of coastal subsidence on the Sele River coastal plain has been examined and measured with local vertical land movement data. The vertical displacements, derived by satellite radar differential interferometry processing (Ps‐InSAR), show that the analysed coastal sector is characterised by a south‐eastward decrease of vertical subsidence rates. These results have been coupled with sea‐level rise (SLR) scenarios, in order to identify the most critical areas. In general, the subsidence mostly affects areas where alluvial deposits are thicker, the back‐dune areas and the Sele River mouth, all late Holocene in age. Five local SLR scenarios allow identifying zones in the plain potentially prone to inundation and the shoreline retreat for the years 2065 and 2100. For these dates, 2.2% and 7.06% of the investigated area will have a topography lower than the estimated future sea level. Moreover, results show that the extent of the areas potentially exposed to inundation and erosion increases moving from south to north.
