“…The reported mean loss of glacial length over four decades is approximately 621 ± 468 m, with large variations across the Himalayan region (Kulkarni and Karyakarte 2014). Morover, the recent studies on individual glaciers also suggest that most of the glaciers are in retreating phase although the rate of retreat varies from one glacier to another (Mehta et al, 2011;Azam et al, 2012;Bhambri et al, 2012;Pandey and Ghosh 2012;Dobhal et al, 2013;Mehta et al, 2013;Pandey and Venkataraman 2013;Mehta et al, 2014b;Azam et al, 2014;Chand and Sharma 2015b;Nainwal et al, 2016;. Such complexity and variations invites a rigorous and systematic analysis of the Himalayan glaciers instead of direct comparisons and extrapolations of results from wellstudied glaciers in some of the basin to others poorly observed glacierized basin (Chand and Sharma 2015a).…”

“…Such complexity and variations invites a rigorous and systematic analysis of the Himalayan glaciers instead of direct comparisons and extrapolations of results from wellstudied glaciers in some of the basin to others poorly observed glacierized basin (Chand and Sharma 2015a). Besides, the earlier studies on the estimation of glacial area and recession for the Indian Himalaya are based on SoI maps (1960s-70s) and coarserresolution satellite images (Kulkarni et al, 2007;Mehta et al, 2011;Pandey et al, 2011;Mir et al, 2013;Mehta et al, 2013;Pandey and Venkataraman 2013;Mehta et al, 2014b). However, the recent studies suggests that earlier estimations primarily based on SoI maps are highly erroneous and overestimate glacial change, and therefore reassessment and recalculation based on high reolustion images, if possible, are required for more accurate and pragmatic results (Chand and Sharma 2015b;Chand and Sharma 2015a;.…”

In the recent years, number of studies were carried out to define the timing and extent of Quaternary glaciation throughout the Himalayan region. Such studies have helped to understand the past climate changes and further develop predictive futuristic models. There have been 22 research studies that were carried out during the past six years (2010)(2011)(2012)(2013)(2014)(2015)(2016) with equal contribution from Indian researcher and their international counterparts in terms of research output. Most of these studies have focused on the north-western Himalaya, with only a few studies being carried out in the eastern part. Recently published new glacial succession chronology (Terrestrial Cosmogenic Nuclide ( 10 Be TCN), Optically Stimulated Luminescence (OSL), Electron Spin Resonance (ESR) and Radiocarbon ( 14 C)) in these studies provide a synoptic picture of glacial episode for most the Himalayan regions. Major glacial advances occurred during the Last glacial stage and early Holocene, with minor fluctuations during the mid-Holocene. However, recent study suggests contrary to the earlier suggestions that a reasonably large valley glacier expansion occurred during the global Last Glacial Maxmium (LGM), likely in response to global variations in temperature. Keywords IntroductionThe Himalayan region altered large-scale climate systems including the Asian monsoon and considerably influenced the regional and global atmospheric circulation that may have played a key role in the onset of Quaternary glaciation (Molnar and England, 1990;Ruddiman and Kutzbach, 1991;Prell and Kutzbach, 1992;Raymo and Ruddiman, 1992;Benn and Owen, 1998;Owen et al., 2002). Information on the geographic extent and magnitude of Quaternary glaciations in this largest glaciated area outside the polar region is important for understanding the climatic, erosional, and tectonic evolution of this giant orogenic system (Brozovic et al., 1997;Zeitler et al., 2001;Norton et al., 2010;Willett, 2010). Practically in the context of contemporary global warming, climate variability, and associated societal impacts and for a better assessment of regional and global forcing factors for future glacier behavior, it is important to characterize and quantify past glacial changes (Owen, 2009;Scherler, 2010).There is a growing number of chronologic data and studies in recent years, yet there is no general consensus concerning the timing, extent, and climatic forcing of glaciations in the Himalayan region (Gillespie and Molnar, 1995;Owen et al., 2008;Scherler et al., 2010;Owen and Dortch, 2014). This region is fed by two dominant climate systems viz. the Indian summer monsoon (ISM) and the mid-latitude westerlies. The influence of these weather systems varies spatially so much that most of the southern and eastern part of the Himalaya experiences a pronounced summer precipitation which sharply declines northward across the Himalaya. The mid-latitude westerlies are responsible for a winter precipitation maximum at the extreme west of the Himalaya, Trans-Himalaya an...

“…This also confirmed findings of earlier studies (Bolchet, et al, 2008). The pro-glacier lakes present in front of the glacier terminus exhibiting bright tone with fine texture in contrast to coarse and mottled texture over glacier surface helped in defining the lower limits of the glaciers (Pandey, et al, 2012). Methodology flow chart for the inventory of glacier lakes in the study area is shown in the Fig.…”

The present study used the potential of Landsat multispectral data and ASTER-DEM data to identify the changes of glacier lakes in part of Chandra basin and surrounding of Himachal Pradesh of India from 1989 to 2013. The Barashigri, Chotashigri, Hamtahand Parvati glacier are the major glaciers within the area. The Landsat data of TM (1989), ETM+ (2001 and OLI-TIRS (2013) sensors having different band combinations were analysed to monitor variation in the glacier lakes and area of glaciers and terminus whereas ASTER-DEM data was used for relief information. Glaciers terminus and glacial lakes were identified and mapped using false-colour composites (FCC) with band combinations of red, near-infrared (NIR) and shortwave infrared (SWIR), and a true-colour composite of red, green and NIR, of Landsat TM/ETM+ images and normalized difference water index (NDWI) methods. It is observed that the number of lakes in the study area increased by 18.69% during the past 34 years while it was increased from 68 in 1989 to 89 in 2013. During the analysis, it is also found that the snow and glacier covered area within this period is also reduced from 1,317.39 to 1,125.59 km 2 .

“…Besides, a numbers of studies using satellite data were made by Bhambri et al (2011Bhambri et al ( , 2012, Dozier and Hall (1987), Kulkarni et al ( , 2004Kulkarni et al ( , 2005Kulkarni et al ( , 2007Kulkarni et al ( , 2011, Kordzakhia et al (2015), Pandey et al (2012) and Rai et al (2009Rai et al ( , 2013Rai et al ( , 2016. It was showed that the best method for analysis of glaciers is application of combined approach of satellite remote sensing with terrestrial observations and expert knowledge of separate glaciers.…”
