DESCRIPTION:Italy\, with 58 properties inscribed on the World Heritage List
 \, is the country with the highest number of UNESCO cultural heritage site
 s in the world. At the same time\, Italy faces significant natural hazards
  from a geological and soil protection perspective. Particularly\, archaeo
 logical sites and works of art are susceptible to geo-hydrological instabi
 lity and deterioration. In order to understand instability and degradation
  processes it is essential to consider the extent and state of cultural he
 ritage in the context of its geology\, geomorphology\, natural and urban e
 nvironments. This is fundamental to decide the priorities of risks mitigat
 ion practices and protection/conservation strategies.\nThe monitoring of I
 talian cultural heritage is a fundamental activity for their long-term pro
 tection and conservation. Radar interferometric remote sensing techniques 
 are non-invasive contactless and advanced methods capable of determining d
 isplacements and deformations affecting structures and natural slopes with
  millimeter accuracy. They represent powerful tools that can be profitably
  used for monitoring cultural heritage\, architectural structures\, and ar
 chaeological sites without causing any damage\, and at the same time explo
 it several temporal time series\, thanks to the available satellite conste
 llations. \nIn the framework of the Extraordinary Plan for the Monitoring 
 and Conservation of Cultural Property (Piano Straordinario di Monitoraggio
  e Conservazione dei Beni Culturali Immobili)\, an analysis of several Ita
 lian historical-cultural sites (Paestum - SA\, Volterra - PI\, Pienza - SI
 \, Civita di Bagnoregio - VT\, Orvieto - TR\, Populonia - LI) is being con
 ducted by the UNESCO Chair "Prevention and sustainable management of hydro
 geological risk" at the University of Florence. The analysed dataset inclu
 des old and new satellite sensors: from ERS-ENVISAT time series\, to Cosmo
 Sky-Med (comprising data from 2011 to 2014\, and a new acquisition from 20
 15 to 2023)\, and Sentinel data available from the European Ground Motion 
 Service. The data was processed using PSI (Persistent Scatterer Interferom
 etry) techniques\, and combined with geothematic data in a GIS environment
 \; field validation was carried out for each site by means of field survey
 s. The outcomes of this work will provide useful suggestions for damage pr
 evention in the framework of the planning of protection-conservation measu
 res of the cultural assets.\n\nIn support of these activities\, a non-inva
 sive investigation model is proposed that incorporates non-invasive strate
 gies for preventing and monitoring instability and natural hazards. In par
 ticular\, the evaluation of the conditions of the cultural heritage assets
  affected by hydrogeological risk is performed through the methodologies b
 ased on PSI data already tested in the scientific literature to evaluate t
 he conditions of potential instability of the artefacts on a local scale\,
  analyzed considering the remotely detected deformation rates from satelli
 te measurements\, and integrated with background geological data\, constru
 ction characteristics and field evidence.\nThis project aims at developing
  a sustainable system for analyzing and monitoring the architectural and c
 ultural heritage integrity and stability\, incorporating a high level of s
 cientific and technological knowledge\, in order to protect cultural herit
 age threatened by natural hazards\, as well as to give a realistic and cur
 rent picture of hydrogeological risks and vulnerabilities.
