2023 - Increasing Geoheritage Awareness through Non-Formal Learning [Articolo su rivista]
Coratza, P.; Vandelli, V.; Ghinoi, A.
abstract

Non-formal learning can have a crucial role in increasing citizens’ literacy to geoscience providing the opportunity to raise the public profile of geology and geomorphology. Starting from these remarks, the project presented here is one of the first attempts, at national level, aimed at achieving the territorial upgrading based on geoheritage enhancement. The project started thanks to a bottom-up input and involved the collaboration between scholars and local administrations and stakeholders for the valorization of a fluvial area within the Municipality of Castellarano (Emilia Apennines, Northern Italy). To achieve this aim of non-formal learning activities, based on the interpretation of the geoheritage, have been implemented. In fact, the investigated area includes valuable geological and geomorphological features which have been used, in the frame of the project here presented, to promote local geodiversity and geotourism. In particular, three geosites of regional significance were considered for the creation of EarthCaches, interpretative panels and guided excursions. Interpretative contents were designed to be educational, providing accurate but non-technical explanations. Attention was given in including illustrations playing an important role in the learning process. The results revealed that the implemented activities positively contribute to raising public awareness on the value of geoheritage.

2023 - The influence of geographical factors on COVID-19 outbreak: A literature review [Abstract in Atti di Convegno]
Coratza, Paola; Ghinoi, Alessandro; Palandri, Lucia; Righi, Elena; Rizzi, Cristiana; Soldati, Mauro; Vandelli, Vittoria
abstract

A significant number of papers focusing on the relationships between COVID-19 diffusion and geographic factors is available in literature. The same applies to the use of geographic techniques (e.g., spatial tools and mapping) for the study of the pandemic. Although the literature on these topics is already abundant, a detailed and comprehensive review is still lacking. In this context, the purpose of this paper is to fill the existing gap by presenting a literature review of geographical studies dealing with the COVID-19 pandemic. The review is aimed at: i) understanding the role of geographic/territorial determinants (e.g., geographic location of confirmed cases, climatic and environmental characteristics, urbanization) in the spread of COVID-19; ii) identifying common approaches, materials, and methods used in the study of the COVID-19 outbreak from a geographical perspective; iii) recognising possible research gaps to address future in-depth analyses. To achieve these goals a literature review was made concerning the application of geographical approaches for the study of one or more geographical factors/variables, as well as socioeconomic factors in relation to the outbreak and diffusion of the COVID-19 pandemic. The main academic literature databases were inquired. More than 80 papers were reviewed and categorized according to different criteria, e.g., considered variables, investigated period, spatial and temporal resolution and applied methodologies. This research is part of an interdisciplinary project (“DISCOV19”) funded by the University of Modena and Reggio Emilia and aiming at identifying the main vulnerability and risk factors related to COVID-19 outbreak and at formulating prevention and management schemes with a focus on the Province of Modena (Northern Italy). The investigation crosses different disciplines: i) public health epidemiology, investigating the contagion modalities and health and socio-demographic predisposing factors; ii) economic-statistical methodology, pointing out the structural characteristics of the networks that convey the contagion and the main social, technological and management vulnerabilities with respect to COVID-19 spread; iii) geography and geomorphology, for thematic mapping and spatial analysis of COVID-19 outbreak and understanding the role of environmental and physical-geographical factors on COVID-19 incidence. The review here presented fits into this context being one of the first outputs of the project implementation.

2022 - A Literature Review of Climate-Related Coastal Risks in the Mediterranean, a Climate Change Hotspot [Articolo su rivista]
Sarkar, Nabanita; Rizzo, Angela; Vandelli, Vittoria; Soldati, Mauro
abstract

Direct and indirect impacts of climate change are alarming in the coastal areas of the world, including the Mediterranean coasts. Extreme events (such as marine storms, medicanes, etc.) are likely to increase the coastal risks in the region (e.g., erosion, flooding, and inundation), resulting in a significant socio-economic impact, loss of natural biodiversity and ecosystem services, and damage to cultural heritage along the affected coasts. Therefore, climate-related risk assessment procedures are crucial for the management and sustainable development of coastal areas. The purpose of this paper is to review and analyze the literature on the assessment of both the long- and short- term effects of climate change on coastal Mediterranean areas. It emphasizes methods and techniques to evaluate coastal vulnerability and sea level rise risk. This paper presents an overview of relevant scientific literature on the matter with a focus on approaches used in addressing the issues on climate change, as well as the geographic distribution of papers on the topic, highlighting the main aspects addressed in different Mediterranean countries.

2022 - Coastal inundation scenarios in the north-eastern sector of the Island of Gozo (Malta, Mediterranean Sea) as a response to sea level rise [Articolo su rivista]
Vandelli, Vittoria; Sarkar, Nabanita; Micallef, Anton S.; Soldati, Mauro; Rizzo, Angela
abstract

According to the most recent scenarios, sea level is expected to keep rising during the next decades because of global warming. In this context, coastal areas are highly vulnerable to marine and climate-related processes, such as erosion and inundation. Such processes are expected to cause shoreline retreat and local morphological variations with consequent loss in natural ecosystems, exploitable coastal land, and significant socio-economic impacts. This paper aims at outlining future scenarios of potential coastal inundation along the NE coastal sector of the Island of Gozo (Malta). The study assessed expected coastline positions for the investigated coastal stretch by analysing high-resolution topographic data coupled with sea level projections for the years 2050 and 2100, accounting also for the contribution of storm surges. Results are expected to sensitize local authorities and communities about potential threats derived from sea level rise that could affect coastal areas in the near future.

2022 - Potential Sea Level Rise Inundation in the Mediterranean: From Susceptibility Assessment to Risk Scenarios for Policy Action [Articolo su rivista]
Rizzo, A.; Vandelli, V.; Gauci, C.; Buhagiar, G.; Micallef, A. S.; Soldati, M.
abstract

Coastal ecosystems and anthropic activities are prone to be affected by the negative impact of marine-related processes induced by climate change, such as erosion, flooding and permanent inundation. Studies aiming at defining potential risk scenarios represent a valuable tool for the identification of the most suitable coastal adaptation measures. After outlining sea level rise implications at the Mediterranean scale, this paper deals with inundation risk scenarios for the years 2050 and 2100 for the north-eastern sector of the Island of Gozo (Malta), central Mediterranean Sea. The analysis, carried out by applying an index-based procedure, firstly required the evaluation of the susceptibility to inundation of the investigated coastal stretch under different sea level projections. Then, the spatial combination of inundation susceptibility with the exposure and vulnerability of the area allowed identification of the most critical sectors in terms of coastal risk. The results of the analysis showed that, under the worst-case climate scenarios, 5.5% and 8.1% of the investigated coastal sector are prone to very high inundation risk (Class R4) in 2050 and 2100, respectively. In particular, the bays of Ramla and Marsalforn, which are characterized by significant economic and touristic activities, were found to be the sites where the expected impacts of future sea level rise will be higher if no management strategy and adaptation action are taken in the near future.

2020 - Coastal vulnerability assessment along the north-eastern sector of Gozo Island (Malta, Mediterranean Sea) [Articolo su rivista]
Rizzo, A.; Vandelli, V.; Buhagiar, G.; Micallef, A. S.; Soldati, M.
abstract

The coastal landscape of the Maltese Islands is the result of long-term evolution, influenced by tectonics, geomorphological processes, and sea level oscillations. Due to their geological setting, the islands are particularly prone to marine-related and gravity-induced processes, exacerbated by climate change. This study aligns different concepts into a relatively concise and expedient methodology for overall coastal vulnerability assessment, taking the NE sector of Gozo Island as a test case. Geomorphological investigation, integrated with analysis of marine geophysical data, enabled characterization of coastal dynamics, identifying this stretch of coast as being potentially hazardous. The study area features a high economic value derived from tourist and mining activities and natural protected areas, that altogether not only make coastal vulnerability a major concern but also the task of assessing it complex. Before introducing the methodology proposed for overall vulnerability assessment, an in-depth revision of the vulnerability concept is provided. The evaluation was carried out by using a set of key indicators related to local land use, anthropic and natural assets, economic activities, and social issues. Results show that the most critical areas are located east of Marsalforn including Ramla Bay, an important tourist attraction hosting the largest sandy beach in Gozo. The method combines physical exposure and social vulnerability into an overall index. It proves to be cost effective in data management and processing and is suitable for the identification and assessment of overall vulnerability of coastal areas to consequences of climate-and marine-related processes, such as coastal erosion, landslides and sea level rise.

2019 - Bridging terrestrial and marine geoheritage: Assessing geosites in Portofino Natural Park (Italy) [Articolo su rivista]
Coratza, P.; Vandelli, V.; Fiorentini, L.; Paliaga, G.; Faccini, F.
abstract

Interest in geoheritage research has grown over the past 25 years and several countries have issued laws to encourage improvement and conservation. Investigations on geosites are prevalently carried out on land environments, although the study of underwater marine environments is also of paramount scientific importance. Nevertheless, due to the constraints of underwater environments, these sites have been little explored, also on account of the higher costs and difficulties of surveying. This research has identified and assessed the terrestrial and marine geosites of the Portofino Natural Park and Protected Marine Area, which are internationally famous owing to both the land scenic features and the quality of the marine ecosystem. The goal was to pinpoint the most suitable sites for tourist improvement and fruition and identify possible connections between the two environments. In all, 28 terrestrial sites and 27 marine sites have been identified and their scientific value as well as their ecological, cultural, and aesthetic importance has been assessed. In addition, accessibility, services, and economic potential of geosites has also been taken into account. Both the updated database of terrestrial and marine geosites in the Portofino protected areas and the assessment procedure adopted can become useful tools for the managers of these sites and provide decision-makers with possible strategies for tourist development.

2019 - Discovery and dating of Pre-LGM deposits in a high catchment of the Dolomites (Italy): New insights on climate-related geomorphological processes during the Late Pleistocene [Articolo su rivista]
Vandelli, Vittoria; Ghinoi, Alessandro; Marchetti, Mauro; Soldati, Mauro
abstract

The results from the analysis of a relatively deep stratigraphic sequence from a formerly glaciated plateau in the Upper Badia valley (Dolomites, Italy) are discussed, and the first insight on Late Pleistocene sedimentary records and geomorphological evolution of the area are provided. The investigated sequence comprises: i) cohesive sediments interpreted as colluvial-eluvial in origin or as stagnant water deposits; ii) sandy diamicton and dolostone monolithic sediments interpreted as gravity-induced deposits, possibly owing to debris flows or wash out/ reworking of rock avalanche deposits from the surrounding dolomite ridges; iii) silty diamicton interpreted as lodgement till, possibly attributed to the Last Glacial Maximum (LGM). Radiocarbon dating results and interpretation of stratigraphic data, supported by geomorphological field surveys, remote sensing data analyses and palaeoclimatic and palaeo-environmental data from literature, enabled us to conclude that the investigated plateau (Pralongià, ca. 2000 m a.s.l.) was likely ice-free for most of Marine Isotope Stage 3. In particular, between 38 ka BP and the inset of full-glacial conditions (LGM ~ 27 ka BP) clastic gravity-induced sediments were deposited within the study site. Supraglacial transport is supposed to have played a role in the emplacement of gravity-induced deposits fromthe surrounding dolomite cliffs to the plateau. This study resulted in the first Pre-LGM record of sedimentation and palaeo-environmental conditions inside the Eastern Dolomites in the 46 to 38 ka BP period.

2019 - Geomorphology of the central Po Plain, Northern Italy [Articolo su rivista]
Castaldini, Doriano; Marchetti, Mauro; Norini, Gianluca; Vandelli, Vittoria; Clara Zuluaga Vélez, Maria
abstract

A micro-relief map (1:90,000 scale) and a geomorphological map (1:25,000 scale) of the central sector of the Po Plain (northern Italy) are presented. The geomorphological map represents fluvial and anthropogenic landforms as well as the distribution of the textures of superficial alluvial deposits. It resulted from the integration of different study methods, including remote sensing data analysis, field surveys and grain size analysis of superficial deposits. The micro-relief map was a fundamental tool for identifying many inconspicuous landforms. The geomorphological map can provide local authorities with useful information for correct territorial management and planning, in particular for seismic and flood hazard assessment.

2018 - Environmental rehabilitation linking natural and industrial heritage: a Master Plan for dismissed quarry areas in the Emilia Apennines (Italy) [Articolo su rivista]
Coratza, P.; Vandelli, V.; Soldati, M.
abstract

Over the past decades, quarrying activities have produced a vast array of physical and environmental impacts worldwide. In the past 20 years, there has been a growing need to address the issue of rehabilitation and requalification of quarry areas that, to be effective, should be strictly linked to local territorial resources and context, as shown by different types of rehabilitation schemes implemented in different parts of the world. This paper focuses on the rehabilitation of a recently dismissed quarry area in the Rio della Rocca valley (Emilia Apennines, northern Italy), near the ceramic tile district of Sassuolo, which is considered the largest in the world. During the past 50 years, quarrying activity has deeply modified the pristine landscape of this valley, which, however, still holds biotic and abiotic features of great natural interest and scientific value. The methodological approach and actions that led to an environmental rehabilitation scheme, based on the combined appraisal of geological, biological and industrial heritage within a Master Plan, are presented. Territorial resources, restrictions on development, geological hazards, as well as inputs from the local community at different stages were taken into account in defining the Master Plan.

2018 - Geomorphology of the north-eastern coast of Gozo (Malta, Mediterranean Sea) [Articolo su rivista]
Prampolini, M.; Gauci, C.; Micallef, A. S.; Selmi, L.; Vandelli, V.; Soldati, M.
abstract

The paper presents a geomorphological map of the north-eastern coast of the Island of Gozo (Malta) integrating inland and offshore areas at the scale 1:15,000. The map derives from the integration of different methods, such as aerial photo interpretation, field surveys and analysis of seafloor bathymetry. The landforms identified on land were shaped by coastal, fluvial, karst and gravity-induced processes, and some of them prolong on the seafloor. Most of the submerged landforms appear to have been modelled in subaerial conditions during sea-level lowstands, having been sealed by the rising sea in post-glacial times. Two sketches accompany the Main Map showing the type and distribution of coastal geomorphotypes and the land cover of the area.

Soldati, Mauro; Prampolini, Mariacristina; Vandelli, Vittoria
abstract

The paper shows the main results of multidisciplinary research carried out in the Island of Malta aiming at the integration of terrestrial and marine datasets. Identification, mapping, monitoring and dating of landslides, including submerged ones, have enabled to define a time frame for the development of landslides and to reconstruct the geomorphological evolution of the investigated areas. This has provided useful means for landslide susceptibility and hazard mapping, which is crucial for north-west coast of Malta.

2017 - The Great Diversity of Italian Landscapes and Landforms: Their Origin and Human Imprint [Capitolo/Saggio]
Marchetti, Mauro; Soldati, Mauro; Vandelli, Vittoria
abstract

An outstanding variety of landscapes and landforms are present in Italy due to its complex geological history, repeated climate changes and increasing human impact through time. This chapter highlights the reasons for the geological and geomorphological diversity of the country by illustrating its geological evolution since the Mesozoic, outlining the paleogeographic changes that occurred as a consequence of Quaternary climate variations, and tracing the unique human civilization history that has so strongly influenced landscape evolution since the Neolithic . Special attention is devoted to the complex history of the country, where peoples coming from different geographical areas met each other contributing to make Italy a compendium of cultural diversity capable of attracting travellers from all over the world. Landscape conservation and protection are finally taken into account.

2017 - Tutela e valorizzazione di una risorsa per il territorio: la valle del Rio della Rocca (Appennino reggiano) [Articolo su rivista]
Coratza, Paola; Soldati, Mauro; Vandelli, Vittoria
abstract

Conservation and improvement of a natural territorial resource: the valley of Rio della Rocca (Italy). The quarrying activities carried out since the 1950s have deeply modified the lower-middle sector of the Rio della Rocca valley in the municipality of Castellarano (Reggio Emilia Apennines, Italy). The great value of the natural elements is, however, accompanied by environmental degradation, mainly due to abandoned quarries. Interventions aimed at territorial upgrading for the purpose of recreation and tourism had to be devised, taking into account the different naturalistic aspects of the area including its geological features. In order to define suitable strategies and actions, an analysis of territorial restrictions and opportunities was necessary. For this purpose, a detailed review of current legislation was carried out, with particular regard to the provisions stated by the management tools of “Natura 2000 Network”, in which the Rio della Rocca catchment is included as a Site of Community Importance. Among the territorial resources of the area, the scenic value and the exemplarity of its geological heritage are an opportunity to carry out territorial upgrading by assigning the valley to qualified geotourism activities. The sites of most considerable geological interest have therefore been selected, in order to establish preliminary requalification and conservation measures.

2016 - Late Quaternary coastal landscape morphology and evolution of the Maltese Islands (Mediterranean Sea) reconstructed from high-resolution seafloor data [Capitolo/Saggio]
Foglini, F.; Prampolini, Mariacristina; Micallef, A.; Angeletti, L.; Vandelli, V.; Deidun, A.; Soldati, Mauro; Taviani, M.; Vandelli, Vittoria
abstract

The current strong motivation to explore those traces of the archaeological and prehistoric human heritage that presently lie submerged on the continental shelf requires large-scale and precise underwater mapping. One Mediterranean sector deserving particular attention is the Sicily Channel, which is critical for a better understanding of the Africa–Europe migratory routes and early civilization patterns due to its large expanses of shallow seabed that were partially or totally exposed at times of lower relative sea levels. We have focused our attention on the submerged continental margin of the Maltese archipelago. A detailed bathymetric map is here presented, and is discussed in terms of features interpretable as former subaerial landforms and inundated by sealevel rise following the Last Glacial Maximum lowstand at approximately –130 m. Our datasets combine multibeam surveys, Light Detection And Ranging (LiDAR)-derived digital terrain models (DTMs), Chirp sub-bottom profiler records and bottom samples acquired between 2009 and 2012. The main features identified are former river incisions, alluvial plains, karst landscapes (sinkholes, limestone plateaus), slide deposits and palaeoshorelines. This study provides a detailed topographical reconstruction of the palaeolandscape of this key region that is relevant to any future archaeological exploration of the Maltese offshore area.
