Codifying a database framework of climate change geomorphological markers: a study case from southern Italy

Climate change is globally recognised as a key driver of geomorphological transformation increasingly impacting natural systems, particularly through the intensification of erosion processes and modifications to landforms in vulnerable landscapes. This study focuses on landforms, processes, measurement approaches, quantitative methods, and a suitable sampling area from southern Italy, specifically in the middle valleys of Bradano and Basento rivers in Basilicata. The study is undertaken as part of one of the most significant research projects of the Italian National Recovery and Resilience Plan (NRRP), called “Technologies for Climate Change Adaptation and Quality of Life Improvement (Tech4You)”. This project aims to study – among many topics also related to cultural heritage protection and climate change adaptation – the specific framework of natural risks, with particular emphasis on the impact of global climate change in Mediterranean semi-arid areas and soil erosion rates in socio-economically “inner” areas. In this work, we focused on the multiproxy approach needed to discriminate the components of erosion processes at different temporal and spatial scales. Such a goal was approached through the construction of a complex relational database associated with thematic maps produced in a GIS environment. The framework enables the identification of priority areas affected by accelerated erosion and provides a methodological base for replicable climate-change monitoring, including in other Mediterranean semi-arid contexts. Further, it aims to offer a strategic tool for early-warning systems and long-term adaptation planning.
