“…The average surface elevation difference in glacier area is 8.34 m and 7.27 m before and after the correction, which means that a 12.8% error was corrected. Therefore, the ice surface elevation difference and ice volume change reported [27] were probably overestimated.…”

“…The glaciers in the area of the western Qilian Mountains, including TJF, have receded by about 16.9% from the end of Little Ice Age (LIA, from 1622 to 1740) to 1990 [26]. The glacier area on the Su-lo Mountains, part of western Qilian Mountains, including TJF, reported to decrease from 429.1 km 2 in 1966 to 458.2 km 2 in 1999, and the loss in the ice volume were estimated at 1.4 km 3 from 1966 to 2000 via a comparison of the glacier surface elevation between SRTM and DEM in 1966 [27]. However, this study did not account for the error associated with the shift between DEMs and the different resolution [28], [29].…”

Glaciers' runoff in the Qilian Mountains serves as a critical water resource in the northern sections of the Gansu province, the northeastern sections of the Qinghai province, and the northeastern fringe of the Tibetan Plateau. Changes in the glacial area and volume around the highest peak of the Qilian Mountains, i.e., Tuanjiefeng Peak, were estimated using multi-temporal remote-sensing images and digital elevation models, and all possible sources of uncertainty were considered in detail. The total glacier area decreased by 16.1±6.34 km2 (9.9±3.9%) during 1966 to 2010. The average annual glacier shrinkage was −0.15% a−1 from 1966 to 1995, −0.61% a−1 from 1995 to 2000, −0.20% a−1 from 2000 to 2006, and −0.45% a−1 from 2006 to 2010. A comparison of glacier surface elevations using digital elevation models derived from topographic maps in 1966 and from the Shuttle Radar Topography Mission in 1999 suggests that 65% of the grid cells has decreased, thereby indicating that the glacier thickness has declined. The average change in glacier thickness was −7.3±1.5 m (−0.21±0.04 m·a−1) from 1966 to 1999. Glaciers with northeastern aspects thinned by 8.3±1.4 m from 1966 to 1999, i.e., almost twice as much as those with southwestern aspects (4.3±1.3 m). The ice volume decreased by 11.72±2.38×108 m3 from 1966 to 1999, which was about 17.4% more than the value calculated from the statistical relationship between glacier area and volume. The relationship between glacier area change and elevation zone indicates that glacier change is not only dominated by climate change but also affected by glacier dynamics, which are related to local topography. The varied response of a single glacier to climate change indicates that the glacier area change scheme used in some models must be improved.

“…In response, participatory forest management approaches evolved as accepted means in the HKH (Sharma and Chettri, 2003). During the process, it (2000); Wang et al, (2008) was realised that biodiversity management by local people is more effective when the utility value and benefit to communities thereof is evident. For example, successful examples of community-based biodiversity conservation linked to enterprise development include oak-based silk production in Garhwal (India); Jatamansi (Nardostachys jatamansi) in Humla (Nepal); traditional local paper from lokta (Daphne spp.)…”

“…Close to 40% of the land lies within some form of protected area (Table 3). Though there are variations in scale, change in land use and cover is prominent in many parts of the region (Cue and Graf, 2009;Gautam et al, 2004;Wakeel et al, 2005;Wang et al, 2008) with natural habitats shrinking through forest fragmentation (Pandit et al, 2007;Reddy et al, 2013;Uddin et al, 2015), regime shift (Brandt et al, 2013;Joshi et al, 2012), or changes in agriculture land (Semwal et al, 2004) and others. However, habitat degradation is not homogenous across the HKH.…”

Mountains have long been admired and protected on the grounds of their wilderness,character and landscape beauty. But despite their remoteness and low human population density, many mountain ecosystems are strongly affected by drivers of global change. Mountain ecosystems in the tropical and sub-tropical regions have attracted the attention of a number of scientists, policy makers and natural resource managers because of their critical role in the supply of ecosystem services, and their vulnerability to environmental changes induced by anthropogenic and climatic factors. Adapting to and mitigating the effects of environmental change and sustaining ecosystem services in the context of a burgeoning human population is a major challenge.The Convention on Biological Diversity, Millennium Development Goals, and other international agreements explicitly connect conservation to poverty alleviation. It has become clear that nature conservation only works in practice if people's needs are also taken into account; while conservation efforts based on community participation and ownership tend to be more effective. A concerted effort is needed to develop a better scientific understanding of ecosystem structure and functioning and drivers of change as a basis for formulating comprehensive ecosystem management approaches and strategies that link to human wellbeing and poverty alleviation. This paper reviews the state of knowledge on five principle pressures, driving biodiversity loss in the HKH region, and describes evolving processes that highlight reconciliation of the conservation and development perspectives.

“…5 Because glaciers are numerous, widespread, and mostly remote, remote sensing techniques are needed to acquire comprehensive, uniform, and frequent global observations of glacier variations. 19,20 The observation of glacier changes is coordinated by several international programs, including the U.S. Geological Survey (USGS)-led project, Global Land Ice Measurement from Space, which aims to produce a global glacier inventory from advanced spaceborne sensors. This inventory will enable the study of big questions related to future glacier hydrology and global climate.…”

Abstract. Nine Landsat thematic mapper/enhanced thematic mapper (TM/ETM)+ images from 1998 to 2010 were analyzed to detect variations in the Kuksai Glacier of Mt. Muztagh Ata, western China. The velocities of glacial movement were quantified using the normalized cross-correlation (NCC) method. The surface debris cover of the glacier makes automated glacier outline mapping difficult, but provides useful features for monitoring glacier movement with the NCC method. Six displacement maps of the Kuksai Glacier, with an accuracy of 7 m, were derived from the band 3 of Landsat images. The NCC method is proven to be very effective in monitoring the activity of debris-covered glaciers. The results indicate that the velocity of the Kuksai Glacier is high in the upper portion and decreases downstream. For most of the years studied, the variability in the glacier movements in the middle and upper parts of the glacier, especially at 9 to 16 km upstream from the glacier terminal, is much larger than that in the downstream part. This study demonstrates that glacial movements can be routinely monitored using Landsat images, providing an input to and an opportunity for the detailed study of glacier dynamics. © The Authors.
