“…Two separate studies suggest that the contribution of permafrost thaw in headwaters of catchments on the northern fringe of the QTP make up more than one third of total discharge, with half of it made up of precipitation in a lower catchment with limited ice and snow melt (3367 m a.s.l. ), but only 6% from precipitation in a catchment at 4500 m a.s.l., where glacier melt accounts for more than 50% (Yang et al 2016, Zongxing et al 2016. For other mountainous parts of HMA such partitioning is not available.…”

Changing climatic conditions in High Mountain Asia (HMA), especially regional warming and changing precipitation patterns, have led to notable effects on mountain permafrost. Comprehensive knowledge of mountain permafrost in HMA is mostly limited to the mountains of the Qinghai Tibetan Plateau (QTP), with a strong cluster of research activity related to critical infrastructure providing a basis for related climate adaptation measures. Insights related to the extent and changing characteristics of permafrost in the Hindu Kush Himalaya (HKH), are much more limited. This study provides the first comprehensive review of peer-reviewed journal articles, focused on hydrological, ecological, and geomorphic impacts associated with thawing permafrost in HMA, as well as those examining adaptations to changes in mountain permafrost. Studies reveal a clear warming trend across the region, likely resulting in increased landslide activity, effects on streamflow, soil saturation and subsequent vegetation change. Adaptation strategies have been documented only around infrastructure megaprojects as well as animal herding in China. While available research provides important insight that can inform planning in the region, we also identify a need for further research in the areas of hazards related to changing permafrost as well as its effect on ecosystems and subsequently livelihoods. We suggest that future planning of infrastructure in HMA can rely on extrapolation of already existing knowledge within the region to reduce risks associated with warming permafrost. We highlight key research gaps as well as specific areas where insights are limited. These are areas where additional support from governments and funders is urgently needed to enhance regional collaboration to sufficiently understand and effectively respond to permafrost change in the HKH region.

“…Permafrost reduces the hydraulic conductivity of soil, resulting in the reduction of snow meltwater or precipitation infiltration, changing runoff generation, confluence processes, and characteristics in cold regions (Boucher et al, 2010;Li et al, 2014a;2016b;Mu et al, 2018;Shi et al, 2019).…”

Abstract. This study focused on the hydrological and runoff formation processes of river water in the source regions of the Yangtze river during different ablation episodes in 2016 and the ablation period from 2016 to 2018. The effects of altitude were greater for the river in the glacier permafrost area than for the mainstream and the permafrost area during the total ablation period in 2016. There was a significant negative correlation (at the 0.01 level) between precipitation and δ18O, while a significant positive correlation was evident between precipitation and d-excess. More interestingly, significant negative correlations appeared between δ18O and temperature, relative humidity, and evaporation. A mixed segmentation model for end-members was used to determine the proportion of the contributions of different water sources to the target water body. The proportions of precipitation, supra-permafrost water, and glacier and snow meltwater for the mainstream were 41.70 %, 40.88 %, and 17.42 %, respectively. The proportions of precipitation, supra-permafrost water, and glacier and snow meltwater were 33.63 %, 42.21 %, and 24.16 % for the river in the glacier permafrost area and 20.79 %, 69.54 %, and 9.67 %, respectively, for that in the permafrost area. The supra-permafrost water was relatively stable during the different ablation periods, becoming the main source of runoff in the alpine region, except for precipitation, during the total ablation period.

“…The chemical composition of water is the result of long-term interaction between the water body and the surrounding environment in the process of circulation (Bai et al, 2022;Chen et al, 2021;Dai et al, 2022;Fang et al, 2021;Liu et al, 2020;Quan et al, 2021;Xu et al, 2021;Zhang et al, 2021). The history of formation and chemical characteristics of water from streams can be indicated in the basin (Pant et al, 2018;Zongxing et al, 2016). Research on the chemical characteristics of water from the water body in the basin can provide important information for understanding the composition Quality Assurance and Safety of Crops & Foods 15 (1)…”

In order to explore the chemical water characteristics of water-scarce rivers in China, the Ciyao River basin in Shanxi Province was taken as a case study. Water samples of the mainstream and its tributaries were collected in the wet, normal, and dry seasons of 2021. The composition and spatial variation of the main ions in the water body were analyzed using the ion chromatography (IC) instrument. In addition, Pearson correlation analyses were used to evaluate relevant correlation between ion concentrations. The results showed that the overall surface water in the study area was weakly alkaline, and the content of total dissolved solids (TDS) varied greatly, ranging from 702 to 5091 mg/L, with an average of 2897 mg/L. The TDS showed a middle stream > downstream > upstream trend, and the hydrochemical type was Cl · SO4 · HCO3 – Ca · Na. The contents of most ions were significantly changed based on differences in sampling sites and seasons. Natural and human factors influence the chemical characteris-tics of the river. According to the Gibbs diagram and Piper diagram (Figure 3), the ionic composition of the water body in the basin is mainly affected by the joint action of rock weathering and evaporative crystallization. Carbonate rocks constitute the most significant rock weathering, followed by evaporative and silicate rocks. Wastewater from industrial enterprises, agricultural wastewater, and activities of people’s daily living also have some influence on rock weathering. Cation exchange is also important in forming chemical water components in the Ciyao River. The research results can provide technical references and a basis for regional water environment protection, water resources development and utilization, and watershed eco-hydrology research.
