The Po Plain Loess Basin (Northern Italy) : scientific values, threats, and promotion opportunities / I.M. Bollati, A. Zerboni. - In: GEOHERITAGE. - ISSN 1867-2477. - 13:3(2021 Sep), pp. 74.1-74.23. [10.1007/s12371-021-00596-2]
Abstract:
Geoheritage studies periodically propose assessment methodologies addressed to quantify the value of sites of interests towards geoconservation and/or promotion. Loess outcrops in the Po Plain Loess basin (Northern Italy) represent potential geoheritage sites, allowing to reconstruct glacial and interglacial cycles, testifying evidence of paleoseismicity, and preserving traces of Palaeolithic human exploitation along the foreland of the Alpine and Apennine ranges. In this contribution, firstly we propose a brief review on the loess sites in the framework of geoheritage studies. Then, we evaluate the 6 most significant loess outcrops scattered across the Po Plain Loess Basin (Monte Netto Hill, Val Sorda Sequence, Gajum Section, Ghiardo Plateau, Valenza Section, Torino Hill) applying a quantitative methodology aimed at ranking each locality respect to a benchmark site — the Romanengo Plateau — which is the sole loess site included in the Italian Inventory of Geosites. The 70% of sites obtained a global value higher than our benchmark. They show a high diversity, not only from the scientific point of view (i.e., site-intrinsic geodiversity), but also when we consider their Potential for Use. Despite often disregarded in the international panorama, Italian loess sites require a great attention. Moreover, such sites are evolving passive geomorphosites,
thus potentially vulnerable from natural and human causes: this must be considered in the framework of geoconservation and sustainable promotion of each site. Finally, we discuss the possibility of promoting Italian loess sites through different strategies (e.g. virtual tours, 3D models, and gamification based on landscape reconstruction) allowing to visit them by remote and favouring promotion. At the same time, this approach will also promote geoconservation, improving awareness in the general public on the relevance of such sites for Earth (natural and human-related) history.
