The northeastern margin of the Qinghai–Tibet Plateau is an ecologically fragile region that faces severe habitat fragmentation, which directly threatens regional biodiversity conservation and ecological security. To address this challenge, this study constructed a hierarchical “source-corridor-node” ecological network for the Gannan Tibetan Autonomous Prefecture by integrating Morphological Spatial Pattern Analysis (MSPA), the Minimum Cumulative Resistance (MCR) model, landscape connectivity assessment, and gravity modeling. The key results are as follows: (1) The Gannan Yellow River Water Source Replenishment Area contains 11 core ecological source regions, which are predominantly located in the southeastern regions of Diebu County and Zhouqu County, covering a total area of 4237.81 km²; (2) Ecological resistance analysis identifies high-resistance zones concentrated in anthropogenically active river valleys and urban belts (e.g., Hezuo urban area, Awanzang Town, and the G213 corridor). Low-resistance zones are predominantly situated in protected ecological enclaves (e.g., Zhagana Geopark and Gahai Wetland Reserve); (3) A total of 55 ecological corridors were identified, with a total length of 4355.77 km. Among these, 26 were classified as key ecological corridors, primarily distributed in Diebu and Zhouqu counties in the eastern part of Gannan Prefecture. These areas feature relatively concentrated ecological sources, and the key corridors play a critical role in connecting isolated ecological patches and maintaining regional ecological connectivity. (4) Across the entire territory of Gannan Prefecture, a total of 81 first-level ecological nodes and 53 second-level ecological nodes were delineated. As the core hub of the regional ecological network in Gannan Prefecture, Diebu County encompasses 60 First-level and 41 Second-level ecological nodes, respectively. The hierarchical “source-corridor-node” ecological network constructed in this study effectively enhances the overall landscape connectivity of the area. This progressive analytical framework—integrating source identification, corridor extraction, and node diagnosis—provides a scientific basis for biodiversity conservation, territorial ecological restoration, and sustainable development in high-altitude ecologically fragile zones.

The aspiring United Nations Educational, Scientific and Cultural Organization (UNESCO) Global Geopark of Chefchaouen includes part of the Talassemtane National Park (TNP), classified by UNESCO as an exceptional natural heritage site within the Intercontinental Mediterranean Biosphere Reserve (RBIM). The other section corresponds to the Ghomara Coast (GC), characterized by an outstanding succession of metamorphic rocks. This study identifies and highlights the most significant sites of geological interest (geosites and geodiversity sites) in the territory. Forty-two sites are proposed as geological heritage sites, thirty of which are organized into four accessible georoutes (Oued Laou Valley, Ghomara Coast, Talambote–Akchour, and Chaouen–Ametrasse), while the other twelve are located along trails and forest tracks inside or near the TNP. These sites cover a wide range of geological typologies, including structural geology, stratigraphy–sedimentology, paleontology, geomaterials, petrology, geomorphology, and hydrogeology. To classify and rank the sites objectively, a numerical methodology based on the recent literature was applied. Scientific value (SV), Potential Educational Use (PEU), and Potential Touristic Use (PTU) were quantified using multiple criteria, facilitating route selection according to user needs. Degradation Risk (DR) was also measured, providing managers with essential guidance for an appropriate geoconservation plan. Actions consistent with UNESCO Global Geoparks Network criteria are proposed to improve conservation, support education, and promote sustainable tourism, thereby enhancing economic activity in the region. The initiative aims to promote the region’s exceptional geological, cultural, and natural heritage. The Chefchaouen Geopark was designated a deferred candidate during the UNESCO Global Geoparks Council meeting of 8–9 September 2024. According to Section 5.5 of its guidelines, the Council may defer an application for up to two years to allow improvements without requiring a second field evaluation. To consolidate the Chefchaouen candidacy, we developed a strategy to strengthen compliance with UNESCO requirements, reduce the risk of final rejection, and maintain the territory’s credibility with international networks and partners. This work presents an operational, costed, and scheduled roadmap enabling stakeholders at all levels to converge toward a complete and coherent application. Full article

Australian regional communities are actively seeking development pathways that generate local economic value while maintaining environmental and cultural integrity. In this context, GeoRegions have emerged in Australia as a community-led approach for recognising and interpreting geoheritage and associated abiotic–biotic–cultural (ABC) values through geotourism and geoeducation. The GeoRegion concept remains intentionally operationally flexible, but for regional communities encountering a myriad of barriers to sustainable geotourism implementation, any uncertainty for proponents about what constitutes an implementable GeoRegion and what resources and governance arrangements are required for credible and sustained delivery requires resolution. This study developed a stakeholder-informed conceptual model to clarify the practical ‘building blocks’ of GeoRegion establishment and the conditions under which GeoRegions can contribute to sustainability-oriented regional development. Using a design thinking framing and semi-structured interviews with thirteen expert participants, we used semantic discourse analysis to identify the factors perceived as essential to GeoRegion viability and legitimacy. We found that participants expected GeoRegions to be geologically centred, but their perceived value and long-term durability depend on (i) genuine community support and locally legitimate narratives (including Indigenous knowledge where appropriate), (ii) capable champions or coordinating groups, (iii) sustained resourcing for interpretation and visitor readiness, and (iv) a facilitative and not prescriptive role for government. Participants emphasised that GeoRegions should never be constrained by land tenure but cautioned that competing land uses, access logistics and uneven capacity across regions were highly influential in the delineation of feasible boundaries and management intensity. Our GeoRegion model differentiates core inputs (community mandate, knowledge co-production, geoheritage significance, human capacity and funding) from expected outputs (interpretive materials, geoeducation, geotourism, economic development, conservation outcomes and strengthened place identity), and we identify feedback that can either reinforce or erode sustainability outcomes over time. We argue that GeoRegions can provide a low-risk, scalable mechanism for geoconservation-informed regional development, particularly where formal protected-area tools or geopark ambitions are politically or economically constrained, provided that supporting governance and resourcing are treated as essential design requirements.

To provide essential information on geoheritage and geotourism potential in Jiangxi Province—a key region for geoheritage distribution in China—this study summarizes and categorizes the types, grades, and distribution characteristics of geoheritage within local communities. The primary analytical methods included average nearest neighbour analysis, kernel density estimation, and spatial autocorrelation to explore spatial distribution patterns. A total of 202 significant geoheritage sites were identified in Jiangxi Province. Furthermore, an evaluation index system was established using the entropy weight TOPSIS model to assess the geotourism potential of each city. The findings reveal the following: (1) Geoheritage sites in Jiangxi Province exhibit an overall aggregated spatial distribution, although clustering intensity varies among different geoheritage types and grades. (2) Considering both grade and category, the core distribution area of geoheritage is located in eastern Shangrao City, while global-level geoheritage sites are mainly concentrated in the Poyang Lake Plain. (3) Spatial autocorrelation analysis indicates that, except for global-level geoheritage sites, other geoheritage sites display significant spatial agglomeration with positive spatial correlation. Moreover, local-scale spatial association characteristics differ notably according to geoheritage type and grade. (4) The geotourism development potential across Jiangxi Province shows clear spatial differentiation, with higher potential concentrated in the eastern and southern regions. Full article

Geodiversity assessment has become an important tool for understanding the spatial heterogeneity of abiotic elements and supporting conservation and land-use planning in protected areas. This study presents a comprehensive geodiversity assessment of the Mount Cangshan Global Geopark in Dali, Yunnan Province, China. The primary objective was to develop a quantitative geodiversity evaluation model based on spatial density metrics, addressing existing gaps in subjective and non-reproducible assessment methods. The study integrates four key dimensions of geodiversity: geological units, structural geomorphology, hydrogeology, and soils and land cover. By employing a hybrid AHP-CRITIC method to assign both subjective and objective weights to indicators, the study computes the Geodiversity Index (GDI) to quantify and map geodiversity across the geopark. Results show significant spatial heterogeneity, with high-geodiversity areas concentrated in the central and northern regions, primarily driven by tectonic and geological complexity and glacial, fluvial, and hydrological processes. The results indicate that the GDI can be used as a reliable tool for geosite delineation, heritage management, and sustainable tourism development. The findings provide a framework for geodiversity assessment and support landscape-level land-use zoning, conservation prioritization and sustainable land management in mountain geoparks.

Objective: Given the global trend of ecological protection and sustainable development, Global Geoparks have become an essential platform for resource conservation and regional growth. Changzhi City in Shanxi Province, China, is actively applying for Global Geopark status, relying on its rich geoheritage sites, cultural history, and natural landscapes. This paper presents a systematic evaluation of the city’s geodiversity and relic value, analyzes the feasibility of establishing a Global Geopark in Changzhi City, and provides scientific support for Changzhi City’s Global Geopark application. Methods: Geodiversity data were collected by region using a 1:25,000 grid for sampling. Four methods were adopted for evaluation, namely, the Shannon diversity index, Simpson diversity index, entropy weight method (EWM), and Pielou evenness index. Upon comprehensive comparison of the four approaches, the most suitable approach was selected to produce the final results. For the value evaluation of the geoheritage, a combination of the analytic hierarchy process and the entropy weight method was employed. Results: (1) According to the results of all four methods, the geodiversity of Changzhi City is higher in the eastern and western regions and lower in the central area. (2) The geoheritage sites are mainly distributed in the eastern part of the city and have relatively high relic value. (3) Changzhi City contains abundant natural reserves and cultural resources, meeting the fundamental requirements for Global Geopark construction. Specifically, 38 townships across eight counties were identified as potential geopark areas, encompassing 54 geoheritage sites, 76 provincial-level or higher cultural-relic protection sites, and 15 provincial-level or higher natural protected areas, with a total area of 4458.51 km². Conclusions: Our results suggest that the Shannon diversity index is an effective tool for evaluating geodiversity in Changzhi City. Based on the region’s geological and natural conditions, the delineated geopark area is feasible. In summary, our findings provide essential references for the protection and sustainable development of geoheritage sites, geodiversity, and geoparks and offer strong theoretical and data support for Changzhi City’s Global Geopark application.

Skyros Island, the largest island of the Sporades Complex (NW Aegean Sea, Greece), preserves a geologically diverse record spanning from the Upper Permian to the Quaternary, including crystalline and non-metamorphosed carbonate rocks, ophiolitic rocks and mélanges, medium-grade metamorphic units, rare Miocene volcanic rocks, and impressive fossil-bearing sediments and tufa deposits, together with historically significant quarry and mining landscapes. Through a comprehensive evaluation of the geological heritage of Skyros, this study proposes a transferable, results-based framework for geoconservation, geoeducation, and tourism space management within a geopark context. A systematic inventory of twenty (20) geosites, including six (6) flagship case studies, was established based on scientific value, dominant geodiversity type, risk of degradation, accessibility, educational and tourism potential. The assessment integrates the Scientific Value and Risk of Degradation criteria with complementary management and sustainability indicators. The results demonstrate consistently high scientific value across the selected geosites, with several reaching maximum or near-maximum scores due to their rarity, integrity, and reference character at a regional to international scale. Although some geosites exhibit elevated degradation risk, overall vulnerability is considered manageable through targeted conservation measures and spatially explicit visitor management. Based on the assessment results, a network of thematic georoutes was developed and evaluated using route-level indicators, including number of geosites, route length, educational potential, tourism suitability, accessibility, and contribution to responsible geotourism. The study demonstrates how integrated geosite and georoute assessment can support sustainable land management and confirms that Skyros Island meets key criteria for inclusion in the Hellenic Geoparks Network, providing a robust scientific basis for future UNESCO Global Geopark designation.

Chelmos Vouraikos UNESCO Global Geopark is located in North Peloponnesus, Greece. As a member of the Global Geoparks Network, it is valued for its rich geoheritage in combination with its natural and cultural wealth. Several different landforms of international value are located in the area. The scope of this work is to present an overview of its geomorphological features, link them with biodiversity and highlight their value for geotourism. Its geology is complicated due to intense tectonism. Three geotectonic units of the Alpine Orogeny can be found along with post-Alpine sediments related to the Corinth Gulf rifting. The area is highly covered by limestone creating important karst landforms. High peaks surround river valleys and deep gorges create breathtaking landscapes. Some of them cut through high and steep conglomerate slopes. Remnants of past glaciation have been preserved on Mt Chelmos. The exceptional geodiversity of the area is linked with rich vegetation and high endemism. The many identified geomorphological sites highlight the Geopark’s strong commitment to geomorphology and its importance as a key geomorphological destination. Highly visible geomorphological sites with ecological value can also promote environmental awareness and contribute to the protection of biodiversity. Full article

To address the decline in self-consistency and limited spatial adaptability of traditional interpolation methods in complex terrain, this study proposes a terrain-constrained Triangulated Irregular Network (TIN) interpolation method based on UAV point clouds. The method was tested in the southern margin of the Lufeng Dinosaur National Geopark, Yunnan Province, using ground points at different sampling densities (90%, 70%, 50%, 30%, and 10%), and compared with Spline, Kriging, ANUDEM, and IDW methods. Results show that the proposed method maintains the lowest RMSE and MAE across all densities, demonstrating higher stability and self-consistency and better preserving terrain undulations. This provides technical support for high-precision DEM reconstruction from UAV point clouds in complex terrain. Full article

The setting and scope of cooperation between geoparks and their partners significantly affect their professional development, overall sustainability of operation, the attractiveness of the area for visitors and economic stability. The article deals with the concept of cooperative management in the case study of the Banská Bystrica Geopark in the Slovak Republic, which presents a practical and realistic framework for the development of long-term partnerships, their mutual harmonisation and planning of common activities in accordance with the needs of a specific area. The application of these principles is described in the form of a case study, which represents a model educational product called “The Copper Yarn of the Spania Valley”. The resulting model confirms the importance sustainable approach, the importance of cooperation in the development of the product, which was created as a result of targeted cooperation between the Banská Bystrica Geopark and several regional partners, including the local government, professional institutions and stake-holders. The article points out the need to embed solid and clearly defined cooperation approaches into strategic documents at the national and regional levels, points out the need for state support and a clearly defined position of geoparks in the tourism system. The results could significantly contribute to their stability, sustainability and the effective functioning of partnerships in the territory of geoparks. Full article

This study investigates how cultural and natural heritage can inform surface design for fashion, focusing on the development of a capsule collection of geoproducts in the UNESCO Global Geopark of Caçapava do Sul, Brazil. The purpose is to expand the scope of existing geoproducts, often limited to food and souvenirs, by introducing textile-based items that reflect local identity and contribute to sustainability. The research employed an applied, qualitative, and descriptive approach, including bibliographic review, questionnaires with local artisans, and the mapping of existing geoproducts. Data were analyzed through content analysis, and the creative process followed the method of cross-fertilization, which stimulates innovation by combining knowledge from design, geology, and craftsmanship. The design process was organized into four phases—preparation, generation of alternatives, selection, and realization—culminating in the capsule collection Aflora. The collection comprised two thematic lines: Cactaceae, inspired by endemic flora, and Geo, based on local geomonuments. The results demonstrate that surface design can mediate the relationship between fashion and heritage, producing identity-driven and innovative textile products. Three surface-design modules were produced, six product mockups, and two geoproduct prototypes, developed with materials such as wool, felt, sarja, and cotton fabrics. The study contributes theoretically by linking apparel design with heritage valorization, and practically by proposing a replicable model for geoproduct development. Limitations relate to the single case study and qualitative scope, suggesting future research on replication, eco-friendly printing, and market feasibility. Full article

The sustainable development of ecologically sensitive areas, such as geoparks, requires a comprehensive understanding of the complex interactions between tourism expansion and ecosystem services (ESs). This study investigates these relationships through a case study of the Enshi Grand Canyon—Tenglongdong Cave UNESCO (United Nations Educational, Scientific, and Cultural Organization) Global Geopark, a representative karst landscape in China. We developed an integrated analytical framework that combines multi-source data with coupled modeling approaches, including the Integrated Valuation of ES and Tradeoffs (InVEST), Geographically and Temporally Weighted Regression (GTWR), Boosted Regression Tree (BRT), and structural equation modeling (SEM). This framework overcomes the limitations of single-method analyses and enables a comprehensive diagnosis of the spatiotemporal drivers and pathways influencing ES dynamics. Using this approach, we analyzed the evolution of ESs and their driving factors from 2010 to 2020. The results reveal that natural factors remained the dominant drivers of ESs (accounting for over 73% of total variation), while tourism impacts increased substantially over time and exhibited pronounced spatial heterogeneity. Specifically, (1) the tourism-driven expansion of construction land occurred largely at the expense of cultivated land and grassland, directly reducing ESs; (2) proximity to scenic areas intensified negative ecological effects, whereas proximity to roads and hotels displayed more complex, and occasionally positive, influences; and (3) tourism primarily affected ESs indirectly through land use/cover change (LUCC). This study provides a transferable framework for analyzing tourism–ecosystem service interactions and underscores the necessity of ecological zoning and adaptive management in vulnerable karst regions, offering valuable insights for the sustainable governance of other fragile ecosystems worldwide.

The chorematic method represents an innovative and contemporary approach for organizing tourist space, supporting the sustainable regional development of the future UNESCO Geopark, and guiding research, evaluation, and tourism monitoring activities in the area. This study applies Geographic Information System (GIS) techniques to develop a chorematic model illustrating the influence of county capitals, using Oltenia de sub Munte—an aspiring UNESCO Geopark in Romania—as a case study. The area’s complex geographical characteristics make it an ideal context for demonstrating the capabilities of GIS-based spatial analysis, including the use of the Reilly–Converse gravity model, which posits that a city’s influence increases with its population size and decreases with distance. The theoretical and methodological framework integrates spatial analysis and statistical visualization through the use of thematic maps and diagrams to explore the chorematic model and to assess tourism supply and demand. Accordingly, spatial representations based on chorematic modeling are presented, and the dynamics of tourism demand and supply from 2015 to 2024 are analyzed, focusing on the number of tourist arrivals, overnight stays, and the overall tourism offer within the Oltenia de sub Munte Geopark.

Recent bryological surveys conducted at the Khaybar White Volcano site (northwest Saudi Arabia) led to the documentation of 51 bryophyte species, including five liverworts and 46 mosses. Representing approximately 30% of the national bryophyte flora within less than 0.3% of the country’s surface, this site emerged as a regional hotspot of bryological diversity. A systematic catalog was compiled, presenting the biogeography, local distribution, demography, fertility, taxonomy and ecology of all recorded taxa. Notably, two Arabian endemics—Crossidium deserti and Tortula mucronifera—were identified in Khaybar, alongside six previously unknown on the Arabian Peninsula (Anoectangium euchloron, Geheebia erosa, Grimmia capillata, Molendoa sendteriana, Pterygoneurum subsessile, and Ptychostomum torquescens) and six species newly recorded for Saudi Arabia (Anoectangium aestivum, Husnotiella revoluta, Syntrichia pagorum, Tortella nitida, Tortula lindbergii, and Tuerckheimia svihlae). These findings highlighted the conservation value of Khaybar, whose unique geothermal microhabitats (active fumaroles) supported a suite of tropical and thermophilous species otherwise absent in northern Arabia, such as Fissidens sciophyllus, and Plagiochasma eximium. Comparative analysis with the AlUla region revealed a comparable species richness despite Khaybar’s smaller area and indicated substantial ecological divergence. While AlUla’s bryoflora was primarily associated with lithological heterogeneity, Khaybar’s was shaped by geothermal activity. Conservation recommendations emphasize the vulnerability of these specialized bryophyte communities to grazing, trampling, and climate change, and call for long-term monitoring, regulated access, and integration into national biodiversity management strategies.

The Shunku Rumi Geosite, located within the Napo Sumaco UNESCO Global Geopark in Ecuador, offers an exceptional opportunity to explore the igneous geodiversity of the Abitagua Batholith. This study employs an integrative approach combining petrographic, geochemical, and structural analyses to characterize the site’s lithological diversity, mineral assemblages, and emplacement mechanisms. Detailed fieldwork at a 1:3000 scale included geological mapping, 23 intrusive rock samples, and over 100 structural measurements. Laboratory techniques, such as X-ray fluorescence (XRF), X-ray diffraction (XRD), and thin-section petrography, revealed a wide range of mineral phases, with dominant minerals including quartz, plagioclase, biotite, and amphibole. The petrographic and geochemical dataset is consistent with a calc-alkaline affinity, reflecting subduction-related magmatism. Alteration zones, predominantly propylitic, were identified through secondary minerals like epidote, chlorite, and sericite, signaling late-stage hydrothermal processes. Structural analysis shows NE–SW dyke emplacement was controlled by pre-existing fault systems. The study emphasizes the educational and geotourism potential of Shunku Rumi, with its accessible exposures offering a unique platform for geoeducation. These results also underpin the development of field-based learning materials and practitioner guides within the geopark, linking geological processes to local cultural heritage and promoting sustainable development. The findings contribute to the growing efforts to integrate scientific research with community engagement, fostering a deeper understanding of Earth’s dynamic systems within the context of the Amazonian landscape.
