Current observations, however, have indicated that there is no exact definition of such heritage, persons seem to indicate absence or presence depending on the particular scenario. This limitation arises because there is heritage that is absent purely by accident, there is heritage that is purposefully erased, heritage that is forgotten or destroyed by natural, man-made disasters, war or simply heritage that has been modified or rewritten to suit interests; all of which can affect psychology, identity and resilience. These instances of erasure include natural and man-made disasters, climate change, and museum collections held in trust for protection and preservation, to name a few. This paper recommends the extension of the current use and proposition of a definition of absence heritage to provide a more holistic view of the state of affairs. The paper presents an overview of current use, and reasons, using global examples, to aid in formulating a definition and expanding the use with strategies to reduce or mitigate erasure. With this, awareness and resilience can be built in any society.</p></div>","PeriodicalId":36117,"journal":{"name":"International Journal of Geoheritage and Parks","volume":"12 1","pages":"Pages 1-19"},"PeriodicalIF":0.0,"publicationDate":"2023-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S257744412300076X/pdfft?md5=8b991bb0bb284aead60242ff885827ff&pid=1-s2.0-S257744412300076X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139187816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Matterhorn played, from its first ascent in 1865 until today, a very special role in the history of mountaineering, and its remarkable shape has become iconic in Switzerland. As a consequence, the Matterhorn can be analyzed through four time scales:(1) the deep time of tectonics during the Cenozoic era, which saw the thrusting and piling up of the “Pennine nappes,” due to the collision between African and European plates; (2) the Quaternary period of glacial erosion, which carved the Matterhorn into its distinctive pyramidal peak shape;(3) the Anthropocene time of the thawing of high mountain permafrost; and (4) the era of humans or mountaineering, which spans over than 150 years, from the first ascent in 1865 to the recent achievements of modern mountaineering.</p></div>","PeriodicalId":36117,"journal":{"name":"International Journal of Geoheritage and Parks","volume":"11 4","pages":"Pages 624-633"},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2577444123000667/pdfft?md5=5c797823b5eb582089f1aba7c7289f00&pid=1-s2.0-S2577444123000667-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138501899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet, there is a lack of methodological guidelines to inventory and numerically assess a collection of “geoarchaeosites” for heritage conservation and/or tourism purposes. The aim of this paper is to propose an innovative and integrated methodology for the inventory and assessment of geoarchaeological heritage, with an example of application in the Middle Eure Valley (Paris Basin, France). In this work, we suggest the use of the “geoarchaeosite” concept as a contraction of geoarchaeological sites, i.e., sites of particular relevance in understanding past society-environment interactions at the Quaternary or historical time scale. In our approach, archaeological and geomorphological components of a site have the same level of importance, in contrast to the classical approaches on geomorphosites that consider the cultural, archaeological, and/or historical significance of a site as an “additional” value. In the study area, the results provide a selection of 19 geoarchaeosites with contrasted scientific values, ranging from sites of national (fossiliferous site of Saint-Prest, loess-paleosol sequence of Chaudon) and regional rank (Chartres Cathedral and its historical quarry at Berchères-les-Pierres, French Royal Canal Louis XIV-Aqueduct of Maintenon, Megaliths of Changé at Saint-Piat and Eure palaeochannels) to more confidential sites of local interest, with various degrees of vulnerability and potential use. A network analysis of “disconnected geoarchaeosites” according to spatial, chronological, and functional relationships contributes to improving the overall scientific value of the geoarchaeological heritage. Among the prospects that are emerging in the scope of promotional activities, comes the interest of building a digital geoarchaeoheritage platform with a collaborative/participatory aim in order to reinforce heritage ownership by local residents and stakeholders.</p></div>","PeriodicalId":36117,"journal":{"name":"International Journal of Geoheritage and Parks","volume":"11 4","pages":"Pages 669-687"},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2577444123000412/pdfft?md5=fd0ecd588e93cf653364df558bde62c5&pid=1-s2.0-S2577444123000412-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135345143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Geological heritage elements, such as rocks, formations, fossils, structures, and landscapes, offer valuable insights into unique geological events or phenomena. Understanding their significance is crucial for conservation and management purposes. Our study aims to identify and assess the degradation risk of eleven selected geosites based on specific criteria related to their vulnerability to deterioration and potential human impact. The assessment revealed that three geosites, namely the type locality of dacite (Poieni), the paleontological reserve Snail Hill from Vidra, and the Upper Cretaceous rudist-bearing shallow-marine deposit from Crișului Valley, have a high degradation risk, necessitating the development of targeted geoconservation plans. For the Runcuri Karst Plateau, Tășad Geological Reserve, Bedeleu Massif, Turda Gorges, and Călugări Karst Spring, we obtained a moderate degradation risk. Possibility of deterioration of the main or secondary geological elements, deficiency of legal protection, and the easy access of a large number of tourists are the main factors to contribute to the increased degradation risk. Low degradation risk was found for the geological structures located in the Padiș Karst Plateau and Galbena Valley. Their location within the Apuseni Natural Park provides the framework for legal protection. The geological elements in the Sighiștel Valley also present a low risk of degradation due to their location in a little known and visited area. Our results provide a comprehensive evaluation of degradation risk for geosites in the Northern Apuseni Mountains, offering insights into the specific factors contributing to their vulnerability and highlighting the need for protective measures. The research outcomes contribute to the broader field of geological heritage conservation and management, providing guidance on the presentation of scientific information and promoting the understanding and appreciation of geosites.

Specifically, conflicting guidance from different government entities resulted in study participants' concerns related to safety and their lack of choice in removing disease mitigation measures. We also found that earlier crises prepared many entities to survive during the first year of the pandemic and that these entities' return to operations reflect the stages of disaster and crisis recovery.
