Abstract Mountain communities globally are experiencing increasing challenges as climate-induced glacier changes disrupt water resources and agricultural systems. The Hindukush-Karakoram-Himalayan region of Pakistan has been witnessing environmental over the last few decades with widespread impacts on different sectors life. In Shigar Valley Karakoram region, face socio-economic partly attributed to in dynamics, which directly affect availability productivity. This study investigates glacial community livelihoods by integrating modeling a comprehensive socioeconomic survey. Glaciological change was analyzed from 1970 2020 using Open Global Glacier Model, projections under SSP-126, SSP-370, SSP-585 scenarios for 2020–2100. mass balance simulations driven historical climatological data reveal an overall negative trend, despite shorter periods growth regional hydroclimatic anomalies.

Geosites and Climate Change—A Review and Conceptual Framework

Geosciences, Год журнала: 2024, Номер 14(6), С. 153 - 153

Geosites are windows into the geological past, which may be recorded in rocks and their properties, fossil content, landform produced by processes no longer operating. Since histories of sedimentation, life, landscape evolution to a certain extent controlled climatic conditions, some geosites used as illustrations various themes linked issue climate change. In this paper, coherent systematic framework is proposed for how look at through lens Four major aspects relevance recognized: (i) providing evidence changing conditions past; (ii) an environment different than that today place; (iii) extreme weather events; (iv) dynamic geosites, subject change response ongoing The use raise awareness educate public about faces interpretation challenges. particular, linking with requires caution balanced presentation most record changes occurred without any anthropogenic component. preferred focus should on environmental instability general rather specific reasons

1991–2020 climate normal in the European Alps: focus on high-elevation environments

Journal of Mountain Science, Год журнала: 2023, Номер 20(8), С. 2149 - 2163

Abstract Alps are an important geographical area of the European continent and, in this area, temperature increase is most evident. However, 1991–2020 climate normal has still not been thoroughly investigated. Aiming to fill gap with a focus on high-elevation environments, minimum and maximum daily air acquired by 23 automatic weather station were used. The results show that mean annual values for −2.4°C 4.4°C, respectively, warming rate 0.5°C/10 years. comparison between 1961–1990 1971–2000, 1981–2010, 0.3°C, 0.5°C 0.9°C, respectively. also confirm seasonal temperatures rising through whole Alpine arc, mainly summer autumn. This work highlights do seem be affected positive elevation-dependent warming. Instead, was found. If anthropogenic emissions maintain trend last decades, expected 2001–2030 −0.2°C, if compared 1.5°C normal. study now present Alps, provides indications will occur coming years importance carrying out investigations consider only 30-year normal, but recent comparing them each other.

An assessment of the geomorphodiversity and land use/cover change (LUCC) effects associated with landslides in Meghalaya, India

Abstract The Shillong Plateau in the Eastern Himalayas is exposed to high seismicity, neo‐tectonic activity and orographic precipitation that aggravated landslides region by affecting hillslope processes. Landscape development influenced landslide phenomenon depends upon geomorphic processes geomorphodiversity (GmD). It linked intimately with geomorphology, hydrology soil type.

This study analyzed the challenges and benefits of identification promotion a long-distance cycleway in high mountain areas with aim promoting Alpine eco- geo-tourism. We also investigated role e-biking discovering local geodiversity geoheritage sustainable way. In particular, we focused on path from Bormio to Forni Glacier (Upper Valtellina, Italy), within framework “E-bike” Interreg project. performed detailed analysis select points environmental–geological interest (POIs), focus sites increase knowledge natural heritage area. Since these are widespread area, frame project, selected only most exemplary ones, covering wide spectrum attractions, moving geosite (i.e., landslide) paradigmatic example effects climate change (glacier).

Conservation of World Heritage glacial landscapes in a changing climate: The Swiss Alps Jungfrau-Aletsch case

International Journal of Geoheritage and Parks, Год журнала: 2023, Номер 11(4), С. 535 - 552

Опубликована: Июнь 19, 2023

Many glacial landscapes on all continents are inscribed the World Heritage List. Due to climate change, most of glaciers retreating rapidly, thus questioning their Outstanding Universal Value. This paper clarifies what constitutes heritage values and outlines how could evolve in a future with less (or without) ice. For two sites UNESCO Swiss Alps Jungfrau-Aletsch property (the Great Aletsch Glacier Upper Lauterbrunnen Valley), we describe evolution landscape using Past-Present-Future framework. We then evaluate present post-glacial according criteria used literature geomorphosites. The results outline main issues: (1) As retreat, geoscientific value will depend more inherited landforms, such as moraine ridges, which allow understanding Earth history, glacier itself its dynamics. Their protection is therefore an important issue. (2) aesthetic decrease because disappearance (landscape greying). One possible adaptation be shift from tourism, mainly oriented towards contemplation landscape, geotourism, where proposed public.

Climate Change and Geotourism: Impacts, Challenges, and Opportunities

Tourism and Hospitality, Год журнала: 2023, Номер 4(4), С. 514 - 538

Опубликована: Сен. 29, 2023

Climate change and rising sea levels present significant challenges for geotourism destinations activities. Accelerated changes in geomorphological processes threaten or diminish both the physical existence aesthetic qualities of geoheritage assets, hence visitor experience, as well presenting increased new risks from natural hazards. This is particularly a concern mountain coastal areas, also where greater extremes temperature precipitation affect comfort. A literature review was conducted to assess extent which consequences climate have been recognised research. With exception glacier-based geotourism, few studies considered impacts reported planning development adaptation measures. However, didactic potential raising awareness has commonly recognised. wider tourism identified additional destination-supply visitor-demand issues that will sustainability face change. These include motivations, travel behaviour, perceptions destination image, reactions local, national, international mitigation responses, geoethical considerations around carbon footprints sustainable modes travel. Situating within broader body multidisciplinary research should help inform strategies conjunction with measures adapt on sites.
