In 2018, Jackson Hole Mountain Resort (JHMR) in Teton Village, WY, USA, discontinued its International Standards Organization 14001 environmental management system. JHMR needed a replacement voluntary environmental program (VEP) that would empower resort employees to directly mitigate climate change, reduce waste and pollution, minimize water use, and restore biodiversity, along with improving building, education, and purchasing. I developed the Model for Alpine Resort Sustainability (MARS) based on 2 research objectives of improving existing industry-specific VEPs and empowering employees to directly mitigate resort environmental impacts through their work. MARS involves 4 business management principles: (1) use ski industry-specific criteria to drive accountability comprehensively across 25 resort departments; (2) quantify greenhouse gas emissions, using both absolute and intensity or normalized bases, and apply quantification to solid waste production and water consumption; (3) employ modern management techniques and software to focus on action over documentation; and (4) strategically align with the core business objective of alpine resorts to provide profitable outdoor recreation by decreasing costs and increasing revenues. MARS provides the most comprehensive, research-based accounting to date of alpine resort environmental impacts and mitigation indicators. MARS could be applied to larger resorts receptive to change.
The shear strength of topsoil indicates the resistance of surface land to external erosive forces and represents a key variable for inferring the extent and rate of soil erosion. However, the influence of land use on topsoil shear strength is poorly understood. This study aims to examine topsoil shear strength under different land uses in the purple-soiled region of the Three Gorges Reservoir area in China and explore the related factors that control the observed variability. Direct shear tests were performed to determine the shear strength of topsoil in terms of internal friction angle (φ) and cohesion (c) under 5 typical land use systems. The results showed that the topsoil shear stress increases with increasing shear displacement from 0 to 6 mm; thereafter, it remains relatively stable over a further increase of shear displacement from 6 to 10 mm. The shear stress–shear displacement curves display a hardening strain trend. Land use exerts a strong effect on the shear strength through differentiation of soil physicochemical properties. In general, topsoil from orchard land has the highest mean values for clay fraction, φ, and c and the lowest mean values for sand fraction and water content. The topsoil in abandoned land shows the highest mean values for bulk density and silt content. The bulk density and the clay and silt content are the main direct factors controlling the difference in shear strength of the purple topsoil. Organic matter content, total porosity, and sand content represent important indirect factors that contribute to the variability in c and φ values of the studied soils.
Climate change is a threat to ski resorts, the ski industry, and mountain communities that rely on ski tourism. Ski resorts may be able to mitigate some of the social and economic impacts caused by climate change with proactive adaptation strategies. Using historical weather data, future climate projections, and interviews with ski resort managers in Utah (United States), this research investigates the effects of climate change on ski resorts across the state. We examine temperature change at all resorts within the state from 1980–2018 and climate projections from 2021–2100 under different climate change scenarios (RCPs 2.6, 4.5, and 8.5). We also report on semistructured interviews with resort managers to provide insights into how resort leadership perceives the impacts of climate change, is implementing adaptation strategies, and is addressing barriers to adaptation. Many resorts in Utah are warming faster than global averages, and minimum temperatures are rising faster than maximum temperatures. By the end of the century, winter (December–March) minimum daily temperatures in Utah could warm an additional 6.0°C under the RCP 8.5 scenario near northern Utah resorts and 6.6°C near southern Utah resorts. Resort managers are concerned about shorter season lengths, shifting ski seasons, less snow cover, and poorer snow quality. Many resorts are already adapting, with the most common adaptations being snowmaking and diversifying outdoor recreation offerings (particularly during the summer and shoulder seasons). Barriers to adaptation reported by managers include financial costs, adequate water availability for snowmaking, and uncertainty about climate change projections. Climate change is already impacting Utah ski resorts, but adaptation practices can reduce the negative impacts to some degree at most resorts.
Agriculture in the Upper Indus Basin largely depends on the cryosphere, and cultivation is possible only through irrigation. The agriculture system, however, faces challenges in terms of climate, extreme events, water scarcity, and other socioeconomic conditions. Hence, a scoping review was conducted to identify the irrigation systems and coping mechanism in the 4 valleys of the basin. Centuries-old irrigation canals, water distribution, management systems, and coping mechanisms are in place. Adaptation strategies are managed by communities, and some are established and supported by government and development organizations. Successes, in terms of increased income, crop yields, and cost, are widely reported; however, evidence of their efficiency and sustainability is scarce.
An increasing number of sports events are taking place in wilderness and mountain areas. The Laugavegur Ultra Marathon (LUM) is one such event. It follows the 55-km (34.2-mile) route of the Laugavegur trail in the southern Icelandic highlands. The trail has been selected as one of the world's most scenic long-distance hiking trails by many of the world's leading travel media. This paper focuses on LUM runners' attitudes toward environmental issues to identify their values as a group and to examine whether there are different attitudes between Icelandic and international runners. An online survey was distributed to all participants finishing the race in 2018, a total of 553 runners; the response rate was 45.2%. The results reveal that most runners participating in LUM were running for their own personal goals and challenges, using the trail's wilderness setting as a driver to reach their target. As a group, the runners had relatively ecocentric orientations. With regard to environmental values, however, there was a large difference between Icelandic and international runners. The Icelandic runners significantly favored anthropocentric orientations, preferring more infrastructure and services along the route, compared with international runners, who preferred the wild character of the route. When it comes to planning sports events in natural settings, such as mountain marathons in wilderness areas, it is important to raise the environmental awareness of both users and event organizers. Moreover, to sustain the wilderness character of the trail, it is beneficial to attract more runners who have an ecocentric view.

Over 1 billion people are living at the frontlines of climate change in mountain areas, where warming rates outpace the global average and are driving significant changes in environments and ecosystem services. These changes are exacerbating socioeconomic difficulties faced by many mountain communities, and are already intensifying vulnerabilities across mountain areas globally. The situation is indicative of pervasive and consequential deficits in adaptation, and calls attention to the need for a better understanding of existing adaptation efforts, as well as the prospects for increasing the quantity and quality of adaptation action in mountain regions. In response, this MountainAgenda article introduces a conceptual framework for adaptation gaps. It then uses data from 2 major global-scale adaptation reviews to shed light on the nature and true magnitude of the adaptation gap in mountains. It reveals shortcomings in available adaptation options, deficits in the uptake of existing adaptation support, and a general lack of coherence between existing adaptations and keystone global agreements relevant to climate change adaptation. These shortcomings are largely related to soft limits to adaptation that constrain responses across mountain areas. In this article, we provide recommendations for closing the adaptation gap in mountains and suggest that this will require deeply collaborative efforts that are rooted in local needs, aspirations, and ways of knowing, but that are also supported by external capacity building and implementation resources. In many instances, this will resemble a transformative approach to adaptation. The conceptual framework presented here is broadly applicable and can also be utilized to identify and close adaptation gaps in social-ecological contexts beyond mountains.
The COVID-19 crisis has added urgency to an already difficult situation in mountains. Mountain communities are highly dependent on agriculture, tourism, and remittances for their survival, and their vulnerabilities to a range of challenges—including climate change, poverty, and food insecurity—have been exacerbated by the pandemic. This has increased their vulnerability to poverty and hunger. The aftershocks of COVID-19 deepen concern as to whether the Sustainable Development Goals of the United Nations 2030 Agenda for Sustainable Development can be achieved. The Mountain Partnership is the only United Nations alliance of partners dedicated to improving the lives of mountain peoples and protecting mountain environments. Its secretariat is hosted at the Food and Agriculture Organization of the United Nations. It is working to improve opportunities for mountain peoples in the 2030 Agenda spirit of leaving no one behind.
