Caves are rare in northeast Africa and, thus, deserve attention as potential geoheritage objects (geosites). Assessment of Djara Cave and its vicinity (Western Desert, Egypt) has permitted to document unique features, such as the cave itself as a peculiar subsurface landform, speleothems providing data for palaeoenvironmental reconstructions, rock art demonstrating elements of past landscapes, siliceous nodules weathered from Eocene limestones and a network of dry drainage channels indicative of wetter palaeoenvironments. These features are assigned to geomorphological, sedimentological and palaeogeographical types of geoheritage. Djara Cave and its vicinity are proposed as a geosite of national rank; it is vulnerable to anthropogenic stress and needs geoconservation measures and instalment of interpretative signs. This geosite is already popular among tourists, and can be used for further tourism development. More generally, the presence of caves in Egyptian desert areas makes possible the recognition of national speleological heritage that requires special country-level strategies of management.

The present study aims to investigate the diversity index (dv-index) of morphotectonic and geomorphological landforms as one of the scientific value indices for evaluation of the geotouristic potential of the southeastern Lut desert using topographic statistical analysis. Scientific index scoring in most models is based on descriptive assessment by geotourists and experts. Statistical analysis of the dv-index in the present study helps experts to base their scoring on scientific methods. The dv-index is controlled by several items. In the present study, we analyse two of these, including the classification of topographic continuity pattern (TCP) and topographic slope position correlation (TSPC). For this purpose, a network of section lines is used to analyse slope continuity. The TSPC analysis is performed by using two parameters of absolute value and slope position. Results for these two evaluated items indicate a score of 1.46 (out of 2) for the dv-index. Given a rating of 5, the score obtained for the two items is a high one. Therefore, an initial estimate of the dv-index indicates a significant scientific value of the study area.

Interface of Geodiversity with human response can be understood simply as, the natural range (diversity) of geological (rocks, minerals, fossils), geomorphological (landforms, topography, physical processes), soil and hydrological features including their assemblages, structures, systems and contributions to landscapes together with the anthropogenic amalgamation in the landscape system. Geomorphosites are those components of geodiversity that have acquired a scientific, cultural/historical, aesthetic and socio-economic value due to human perception or exploitation (Panizza, 2001). The trans-Himalayan district of Lahaul and Spiti, Himachal Pradesh, India is a landlocked district in trans-Himalaya accessible seasonally through high mountain passes; where the interface is manifested though human response to the geodiversity elements. The abiotic factors play a significant role in generating stimuli and the human response varies accordingly in the study area. It is also known as the Tethyan Himalayan region, where the interface (interactive zone/ crossing point/edge) of Geomorphosites and human response in terms of geotourism has been analysed and mapped. The data has been collected through extensive field work using structured questionnaire survey and field observations at geomorphosites having unique characteristics. The field work has been done in May–June 2017 and June 2018. The assessment of human response in terms of seasonal economy and geotourism has been done using GIS environment, GPS and SWOT analysis. The study highlights that potential geotourism sites have to be further identified, explored and developed in the region and the existing sites have to be conserved in order to harness the tremendous geotourism potential of the region and thereby boosting the seasonal economy.

Within the current research on geomorphosites, the field of mapping is relatively little developed. Studies offering specific mapping methods for geomorphosites are still rare. However, we can observe an important production of maps used for tourism means: 'geotourist maps'. This study focuses on such maps. The statistical analysis of fifty or so geotourist maps has allowed us to group them into five categories. This article will discuss the statistical method used (hierarchical cluster analysis) as well as the results obtained. The maps are described according to their graphic components and study of their use illustrates their shortcomings in terms of the transfer of geoscience information. In conclusion, we offer some possibilities for the improvement of geomorphosite mapping for tourist use.

Kartowanie geoobiektów jest dziedziną względnie zacofaną w stosunku do innych aspektów ich badań. Rzadko ukazują się prace poświęcone specyficznym metodom kartowania tych obiektów, natomiast na rynku pojawia się coraz więcej map "geoturystycznych". Niniejszy artykuł poświęcony jest właśnie temu typowi map. Pokazano zastosowanie hierarchicznej analizy klastrowej do analizy statystycznej około pięćdziesięciu map geoturystycznych, co pozwoliło na wyróżnienie pięciu typów tych map. Zostały one opisane z punktu widzenia składników graficznych i zastosowania. Wykazano ograniczenia w sposobie przekazywania informacji z zakresu nauk o Ziemi. We wnioskach zaproponowano usprawnienie kartowania geoobiektów dla celów turystycznych.
