Risk Analysis of Stratified Landscapes: Toward an Integrated System for Documenting and Managing Cultural Heritage in Southern Sicily

This study presents the preliminary results of the design and implementation of an advanced data management infrastructure developed to enhance the study, interpretation, and preservation of historical and archaeological contexts. Conducted within the framework of the PNRR CHANGES Project, Spoke 6, the initiative promotes the integration of scientific research, digital innovation, and cultural heritage enhancement. One of the principal outcomes of the project is the development and configuration of ARPAS (“Analisi del Rischio nel Paesaggio Stratificato” or “Risk Analysis of Stratified Landscape”), a centralised Geospatial Database capable of ensuring reliable data archiving, real-time analytical processing, and collaborative information sharing among researchers and institutions engaged in cultural heritage management. The paper discusses key methodological challenges related to the heterogeneity of available documentation and the limitations of existing tools currently used for heritage research and protection in the Italian, and particularly Sicilian, context. At the same time, it highlights the potential of the proposed system in terms of data accessibility, verifiability, and query ability, as well as its ability to integrate and interrelate heterogeneous datasets within a multilayered, interdisciplinary framework for cultural landscape research. The pilot deployment focuses on a geographic area in southeastern Sicily, drawing upon documentation of the cultural landscape across four provinces—Agrigento, Catania, Ragusa, and Siracusa—and integrating archaeological, architectural, and environmental data to support risk assessment and heritage conservation strategies. Results appear to demonstrate ARPAS’s potential to improve the completeness of information, manage stratification across temporal layers, and support predictive and preventive analyses for cultural heritage at the landscape level.
