A Methodological Framework for Multi-source Data Analysis for the Assessment and Preservation of Cultural Heritage

The wide range of risks posed by climate change that could potentially affect Cultural Heritage necessitates a multidisciplinary approach, as well as an initial examination of existing methods for risk assessment across various fields. Thus, the initial focus of the research conducted by the Sapienza PNRR work group was on a multidisciplinary framework to support the risk assessment process relat ing to the multivariate effect of climate change and the interaction of different risks on the tangible outdoor heritage. The research sets out to create a multidisciplinary framework aimed at supporting the risk assessment process, grounded in the clas sification of cultural heritage and aligned with European definitions and protocols. To gather the necessary information, such as hazard classifications, indicators, indi ces and thresholds, various methodologies were employed, including the analysis of major international protocols and EU research projects related to risk assessment involving cultural heritage, expert-based knowledge and a systematic review of the literature. The research seeks to address a gap in the field of quantitative, indicator-based risk assessment, in which a unified, comprehensive framework capable of consolidating in a single repository the main natural and anthropogenic risks, along with the associated taxonomy, does not yet exist. The framework is designed to be consulted by researchers, professionals, and public administrations, facilitating the evaluation of potential risks to the outdoor tangible heritage while allowing users to incrementally add exposure and vulnerability data for each specific risk.
