Abstract:

Microplastic pollution is an emerging environmental concern, and has been found in remote regions, including the high Himalaya mountains. However, the abundance and sources of microplastics in the region are not well documented. This research investigated the abundance, types, and potential sources of microplastics in the Sagarmatha National Park (SNP), a rural and sparsely populated region of Nepal on the southern side of the Himalaya mountains. Water samples were collected from streams and tributaries in SNP in May of 2022. The average microplastic concentration among all samples was 2.0 ± 1

Abstract:

Rural out-migration is a worldwide phenomenon that is also visible in many mountainous regions, creating the impression of an abandoned landscape. In order to achieve sustainable mountain development, it is crucial to understand the various drivers and implications of out-migration in the mountains. Using both secondary and primary data on migration, this study examines different aspects of migration in the Garhwal Himalaya. Secondary data on migration were derived from a report published by the Rural Development and Migration Commission of Uttarakhand in 2018 that included migration statistic

Abstract:

AbstractThe high Himalayan mountains in the north of India are important sources for generating and maintaining the climate over the entire northern belt of the Indian subcontinent. They also influence extreme weather events, such as the western disturbances over the region during winter. The work presented here describes some current trends in weather and climate over the western Himalaya and suggests some possible explanations in the context of climate change. The work also shows how the special features of Indian orography in the western Himalaya affect climate change in the long term, chan

Abstract. Recent concerns related to the potential impacts of the retreat of Himalayan glaciers on the hydrology of rivers originating in the catchment basins of the Himalaya have been accompanied by few analyses describing the role of glaciers in the hydrologic regime of these mountains. This is, at least in part, a result of the relative inaccessibility of the glaciers of the Himalaya, at altitudes generally between 4000–7000 m, and the extreme logistical difficulties of: 1) reaching the glaciers, and 2) conducting meaningful research once they have been reached. It is apparent that an alter

Abstract. The elevation history of the Himalaya–Tibet orogen is central to understanding the evolution and dynamics of both the India–Asia collision and the Asian monsoons. The surface elevation history of the region is largely deduced from stable isotope (δ18O, δD) paleoaltimetry. This method is based on the observed relationship between the isotopic composition of meteoric waters (δ18Op, δDp) and surface elevation, and the assumption that precipitation undergoes Rayleigh distillation under forced ascent. Here we evaluate how elevation-induced climate change influences the δ18Op–elevation rel

Abstract. The cryosphere reacts sensitively to climate change, as evidenced by the widespread retreat of mountain glaciers. Subsurface ice contained in permafrost is similarly affected by climate change, causing persistent impacts on natural and human systems. In contrast to glaciers, permafrost is not observable spatially and therefore its presence and possible changes are frequently overlooked. Correspondingly, little is known about permafrost in the mountains of the Hindu Kush Himalaya (HKH) region, despite permafrost area exceeding that of glaciers in nearly all countries.

Abstract:

The glacier snowline altitude (SLA) at the end of the melt season is an indicator of the glacier equilibrium line altitude and can be used to estimate glacier mass balance and reconstruct past climate. This study analyzes the spatiotemporal variability in glacier SLA across High Mountain Asia, including the Altai Mountains, Karakoram Mountains, Western Himalayas, Gongga Mountains, Tian Shan, and Nyainqentanglha Mountains, over the past 30 years (1989–2019) to better elucidate the state of these mountain glaciers. Remote-sensing data are processed to delineate the glacier SLA across these mount

Abstract. The Himalaya mountains along the southern edge of the Tibetan Plateau act as a natural barrier for the transport of atmospheric aerosols from the polluted regions of South Asia to the main body of the Tibetan Plateau. In this study, we investigate the seasonal and diurnal variations of aerosol optical properties measured at two Aerosol Robotic Network (AERONET) sites on the southern side of the Himalaya (Pokhara, 812 m above sea level (a.s.l.) and EVK2-CNR, 5079 m a.s.l. in Nepal) and one on the northern side (Qomolangma (Mt.

Abstract:

The Himalayan Mountainous region is the world's newest, fastest, and most enormous crumpled mountainous range. It is highly volatile because of the continuous geological process. The entire Himalayas range has been responding to devastating natural hazards, which reflects its fragility and susceptibility. The temperature ranges from low-lying hills and mountains to high-altitude, continuously snow-capped mountainous ranges. According to studies, the temperature revolution had a profound effect on the Mountains, and as a result, weather patterns and disasters have changed substantially. The Mou

Abstract:

The species delimitation of Triplostegia has been controversy and traditionally includes two species: T. glandulifera and T. grandiflora. These two taxa differs in some morphological characters on leaves, size of corollas, and achene involucel apex. A recent study proposed to merge these two species into a single taxon, T. glandulifera, while the phylogenetic and morphological evidence suggests that this genus consists of three distinct species, including an undescribed species that is distributed in the Hengduan Mountains Region and east Himalaya.

Abstract:

The Ayeyarwady River in Myanmar is one of the largest rivers in Southeast Asia. It is predominantly fed by monsoonal precipitation and, to a lower extent, by meltwater from glaciers located in the Himalaya mountains. Information about the glaciers in its headwater region and glacier changes is scarce. Glaciers, in general, are highly important for the hydrological system and are contributing to river flow, therefore playing a key role in water availability, especially in catchments with (semi-) arid downstream areas as is in parts of Myanmar. This study investigated 130 glaciers in the Ayeyarw

Abstract:

GIS-based kinematic stability analysis in rock slopes is a rare practice in geological engineering despite its immense potential to delineate unstable zones in a mountainous region. In this article, we have used a GIS-based modified technique to assess the efficiency of kinematic analysis in predicting shallow landslides in the rock slopes of the Himalayan mountains on a regional scale. The limited use of this technique is primarily due to the complexities involved in its practical application. To make this technique more effective and convenient usability, we present modified methods and a ne

Abstract:

Land surface elevation, climate and vegetation are intrinsically linked at a range of spatial and temporal scales. In the case of Asia, complex relief hosts some of the richest biodiversity on our planet and is dominated by a system of monsoons, the features of which are determined in large part by topography and land surface characteristics, including vegetation. Such regions have not only acted as an incubator for evolving species but also as refugia during periods of environmental crisis. The exceptional topography of Asia includes the largest and highest elevated region on Earth, the Tibet

Therefore, its river runoff variability must be properly monitored.
