Today, dismissed mines are considered significant local tangible and intangible cultural heritage elements and they are more and more often at the core of dedicated enhancement processes, being sometimes inscribed in the UNESCO list; included in geoparks; transformed worldwide into industrial museums; or reused. Italy has a peculiar approach to the topic even if it has been underestimated, and research in the field might be improved. Which models should be looked at? Is it possible to identify some basic criteria to look at to obtain positive results? If yes, where should one start? Our proposal is that the application to the newly born class underground built heritage (UBH) can provide instruments for their historical functional classification and introducing several criteria for their interpretation and reuse could eventually support future enhancement projects in this specific sector. This methodology has been already applied worldwide to this category of good, giving positive results and motivating the authors to continue the research following this hypothesis, with the aim of creating a framework of good practices to be used as a reference for new projects. This paper summarizes the authors' research in this direction. After the introduction of the academic scenario and the UBH theoretical approach, this study proposes the results from applying this new methodology to several worldwide case studies from Greece, Germany, Italy, Japan, and Poland in order to evaluate best practices and/or unsuccessful stories. This study, based on data collected during onsite inspections by the authors within several international financed projects, consists of two steps. In the first, a general overview of all the aspects connected to the historical and contemporary reuses of dismissed mines under analysis was carried out, proposing a reclassification on the basis of the UBH methodology. The second section is dedicated to a new case study: Valle Imperina dismissed mines complex. This section includes an analysis of tangible and intangible values connected to the site and that of the state of the art of the corresponding enhancement. At the end, an evaluation of its potentialities and some critical issues was conducted. [ABSTRACT FROM AUTHOR]

The concept of a UNESCO Global Geopark (UGGp) itself implies that the integration of geological, biological and anthropogenic factors and related values, both tangible and intangible, are at the base of any interpretation, communication, educative practices and enhancement aiming at strengthening the sense of place in local communities, as well as guiding those areas toward sustainable economic growth. However, the measures and good practices codified for UGGps limit their impact on the properties' boundaries, sometimes neglecting the strong natural, social and cultural link between the listed areas, their surroundings and other serial geosites. The paper introduces a five-step study on selected examples of Geoparks and geosites in Italy, Japan and Tunisia, sometimes also including areas inscribed in the UNESCO list as cultural sites, focusing on the possible role of UGGps as drivers for sustainable development of geotourism. The research considers the contextualization of UNESCO UGGps within a broader territorial scale, introducing the concept of Diffused Geopark as a new opportunity in protection and management practices and as a driver for local economies and internationalization of lesser-known contexts.

The role of geological and geotematic mapping has recently come to the forefront in spatial/environmental management. This paper aims to present some cases of boundary extension in the use of contemporary cartographic tools (GIS and WEBGIS). The potential of digital maps and associated databases offers a wide range of applications, responding to the urgent need to make available to users (practitioners in the technical sectors, planners and society as a whole) the most important concepts to concretely achieve better land management, active risk prevention and sustainable resource enhancement. The application of geomorphological maps to issues closer to society can effectively create its approach to more properly technical-scientific issues, fostering a shared awareness, useful in protecting and enhancing the fragile Italian territory. The described experiences focus on GIS, which confirms its effectiveness both for social involvement in environmental issues, and in territorial/environmental management. [ABSTRACT FROM AUTHOR]

Path-based methods for the determination of nondispersive drainage directions in grid-based digital elevation models are presented. These methods extend the descriptive capabilities of the classical D8 method by cumulating the deviations between selected and theoretical drainage directions along the drainage paths. It is shown that either angular or transversal deviations can be employed. Accordingly, two classes of methods designated D8-LAD (eight drainage directions, least angular deviation) and D8-LTD (eight drainage directions, least transversal deviation) are developed. Detailed tests on four synthetic drainage systems of known geometry and on the Liro catchment (central Italian Alps) indicate that the proposed methods provide significant improvement over the D8 method for the determination of drainage directions and drainage areas.

In alpine environments at middle latitudes, the spatial distribution of mountain permafrost is strongly controlled by local climatic conditions, and specifically by snow cover. We present a physical model, PERMACLIM, which uses as input data a Climatic DataBase (CDB) and Digital Elevation Model (DEM). The model calculates the Mean Annual Ground Surface Temperature (MAGST) for each point of the DEM including the snow buffering effect according to the heat conduction theory, which uses both the CDB and field measurements of snow thermal characteristics. PERMACLIM provides a permafrost map based on MAGST values, where permafrost is designated as absent, probable or present, respectively, with MAGST values higher than 0 °C, ranging from 0 to −2 °C and lower than −2 °C. PERMACLIM can be improved by incorporating the ground surface temperatures during the snow-free period when solar radiation provides energy to the ground surface (PERMACLIM B). Both models have been tested in the “Passo del Foscagno” area, Italian Central Alps, comparing the output with the known permafrost distribution (obtained with geophysical investigations and borehole data) and with the permafrost distribution derived by Bottom Temperature of winter Snow cover (BTS). The model prediction of the permafrost distribution gives a good result compared with the permafrost distribution detected with geophysical investigations. Work to include snow redistribution by wind, snow melting and vegetation influences should further improve these results. [Copyright &y& Elsevier]
