“…On the other hand, in the Khasi and Jaintia Hills region, the lower GmDI values are limited to the upper Plateau due to gentle slopes and flat terrain. Here, it is worth mentioning that GmD increases towards the depression and valley zones of the study area (similar to Moradi et al, 2021). When compared with geology, ~73% of very high GmD zones are in the regions of late Mesozoic to early Cenozoic era ES formation (41.54%) and unclassified Gneissic complex of Archean to Paleoproterozoic aeons formation underneath (31.36%).…”

The Shillong Plateau in the Eastern Himalayas is exposed to high seismicity, neo‐tectonic activity and orographic precipitation that aggravated landslides in the region by affecting hillslope processes. Landscape development is influenced by landslide phenomenon and depends upon geomorphic processes and geomorphodiversity (GmD). It is linked intimately with geomorphology, hydrology and soil type. This study uses a remote sensing and GIS‐based approach to assess the spatial linkage between GmD and landslide distribution in Meghalaya (India). GmD index (GmDI) is developed using geological, morphometric and geomorphological parameters and analysed with landslide distribution. The landslide distribution considering land use/cover change (LUCC) is also examined. The result shows that the region with high‐relief, valley and depression zone, mainly along the Dauki fault, have a high to a very high GmDI. About 61% of landslide localities are in zones of high GmDI, concentrated in the central and eastern parts of Meghalaya. Density analysis of the very high class (class 5) of GmD confirms the same. Most of these landslides occur in dense and light‐vegetated landmasses. However, the LUCC analysis reveals a significant increase in the built area on steeper slopes (average expansion ratio of 2.30 for slopes >15°) between 2017 and 2022, indicating a rising threat of landslides in urban areas of Meghalaya. The study presents the importance of GmD in active tectonic regions with particular reference to landslide potential and recent LUCC. It can aid decision‐makers in planning sustainable developments and risk mitigation strategies for landslide hazards and geoconservation.

“…In this approach, the importance of integrating RS-based indicators derived from DEM/DSM becomes apparent. Moradi et al [22] assessed geomorphodiversity and geomorphological heritage for Damavand Volcano Management. Therefore, he coupled in situ fieldwork informations, topography, geological maps, and RS-based indicators to quantify DEM/DSM and their derivatives.…”

“…Panizza [20] later developed his concept even further and integrated the intrinsic and extrinsic values of the geological heritage of the Dolomites, based on a subset of geomorphological indicators, such as stratigraphic, palaeontological, geomorphological and mineralogical indicators [20]. In numerous other case studies, geomorphodiversity indicators have been used to assess the relationship between geomorphodiversity and sediment connectivity in a small alpine catchment [21], to assess the geomorphodiversity and geomorphological heritage for Damavand Volcano Management [22], as well as in various geomorphodiversity indicators [23] and guidelines for generating landform geomorphodiversity maps [24].…”

Remote Sensing of Geomorphodiversity Linked to Biodiversity—Part III: Traits, Processes and Remote Sensing Characteristics

et al. 2022

Remote sensing (RS) enables a cost-effective, extensive, continuous and standardized monitoring of traits and trait variations of geomorphology and its processes, from the local to the continental scale. To implement and better understand RS techniques and the spectral indicators derived from them in the monitoring of geomorphology, this paper presents a new perspective for the definition and recording of five characteristics of geomorphodiversity with RS, namely: geomorphic genesis diversity, geomorphic trait diversity, geomorphic structural diversity, geomorphic taxonomic diversity, and geomorphic functional diversity. In this respect, geomorphic trait diversity is the cornerstone and is essential for recording the other four characteristics using RS technologies. All five characteristics are discussed in detail in this paper and reinforced with numerous examples from various RS technologies. Methods for classifying the five characteristics of geomorphodiversity using RS, as well as the constraints of monitoring the diversity of geomorphology using RS, are discussed. RS-aided techniques that can be used for monitoring geomorphodiversity in regimes with changing land-use intensity are presented. Further, new approaches of geomorphic traits that enable the monitoring of geomorphodiversity through the valorisation of RS data from multiple missions are discussed as well as the ecosystem integrity approach. Likewise, the approach of monitoring the five characteristics of geomorphodiversity recording with RS is discussed, as are existing approaches for recording spectral geomorhic traits/ trait variation approach and indicators, along with approaches for assessing geomorphodiversity. It is shown that there is no comparable approach with which to define and record the five characteristics of geomorphodiversity using only RS data in the literature. Finally, the importance of the digitization process and the use of data science for research in the field of geomorphology in the 21st century is elucidated and discussed.

“…Over the past decade, there has been a notable increase in the number of studies focused on geoheritage evaluation in arid environments, particularly in the MENA (Middle East-North Africa) region. This surge is especially evident in countries such as Iran [11,[38][39][40][41][42][43][44][45][46][47][48][49][50], Egypt [24,[51][52][53][54][55][56][57][58][59] and Morocco [60][61][62][63][64][65][66][67]. The majority of these investigations involve inventories or inventory-based evaluations, which correspond to the initial stages of geoheritage conservation proposed by Brilha [9].…”

A rigorous assessment is an essential part of geoconservation, and choosing an appropriate evaluation method is essential for this process. Globally, an increasing number of sites are being assessed for their geoheritage values, but the most popular methods have been created by researchers with experiences centred in Europe, without considerations of regional differences. To understand whether regional perspectives are required in the evaluation process, this study developed a new method targeting the scientific value of Quaternary geoheritage sites in arid environments, using input from 49 researchers in geosciences and related disciplines with interests in arid landscapes. The results demonstrated the need for a new or modified method, given the different preferences in the weighting system and the necessity to include additional criteria specific to the type of sites targeted by the study. The strong preference to include a new criterion on connections with archaeology/anthropology highlighted the significance of the interdisciplinary scientific values of Quaternary geoheritage sites in arid environments. These findings imply the need for regional diversity or adjustments in geoheritage evaluation. Future research is required to consider such differences for geoheritage values beyond the scientific dimension, such as educational values and touristic values in diverse geographical settings. This article is part of the Theo Murphy meeting issue 'Geodiversity for science and society'.
