“…Another reason is a dynamic behaviour of the lakes. In contrast to changes in the area of glaciers, which retreated in the region during the 2000s (Severskiy et al, 2016; Table S1), both the expansion and formation of lakes and their drainage were registered, and the average statistics conceals significant variations.…”

“…Ice thickness distribution for all glaciers larger than 0.1 km 2 has been calculated based on the outlines of glaciers as in 2000 generated as part of regular cataloguing of glaciers of Kazakhstan (Severskiy et al, 2016) and SRTM DEM surface topography. To reduce the influence of small-scale surface undulations in the ice thickness modelling, SRTM DEM with 30 m resolution was down-sampled to 75 m cell size.…”

“…While no continuous records exist for the assessment period in the Djungarskiy Alatau, mass balance records from the Tuyuksu glacier in the Zailiiskiy Alatau show predominantly nega-tive annual and strongly negative cumulative mass balance (Severskiy et al, 2016). The mass balance data derived from GRACE and ICESat (Farinotti et al, 2015) show that values of negative mass balance in the Djungarskiy Alatau are close to those observed in the Zailiiskiy Alatau and indicate a mass loss of approximately −0.5 × 10 3 kg m −2 a −1 .…”

“…The mountains of Asia, including the Pamir, Tien Shan and Djungarskiy (Jetysu) Alatau, where currently glaciers occupy about 16 427 km 2 (Sorg et al, 2012), are no exception. Across this region, glaciers retreated, losing both area and mass (Solomina et al, 2004;Shahgedanova et al, 2010;Kutuzov and Shahgedanova, 2009;Sorg et al, 2012;Yao et al, 2012;Farinotti et al, 2015;Pieczonka and Bolch, 2015), with the highest retreat rates reaching 1 % a −1 reported for the northern Tien Shan and Djungarskiy Alatau (Narama et al, 2010a;Severskiy et al, 2016).…”

“…The Djungarskiy Alatau is one of the mountain regions of Central Asia where lakes are particularly widespread and where glacier retreat rates are among the highest in the region (Severskiy et al, 2016). Between 1955 and2011, 48 % of the glacier area was lost; between 2000 and 2011, glaciers lost 12 % of their combined area (Table S1 in the Supplement), retreating at a rate of 1.1 % a −1 .…”

Abstract. Changes in the abundance and area of mountain lakes in the Djungarskiy (Jetysu) Alatau between 2002 and 2014 were investigated using Landsat imagery. The number of lakes increased by 6.2 % from 599 to 636 with a growth rate of 0.51 % a −1 . The combined areas were 16.26 ± 0.85 to 17.35 ± 0.92 km 2 respectively and the overall change was within the uncertainty of measurements. Fifty lakes, whose potential outburst can damage existing infrastructure, were identified. The glacier bed topography version 2 (GlabTop2) model was applied to simulate ice thickness and subglacial topography using glacier outlines for 2000 and SRTM DEM (Shuttle Radar Topography Mission digital elevation model) as input data achieving realistic patterns of ice thickness. A total of 513 overdeepenings in the modelled glacier beds, presenting potential sites for the development of lakes, were identified with a combined area of 14.7 km 2 . Morphometric parameters of the modelled overdeepenings were close to those of the existing lakes. A comparison of locations of the overdeepenings and newly formed lakes in the areas deglacierized in [2000][2001][2002][2003][2004][2005][2006][2007][2008][2009][2010][2011][2012][2013][2014] showed that 67 % of the lakes developed at the sites of the overdeepenings. The rates of increase in areas of new lakes correlated with areas of modelled overdeepenings. Locations where hazardous lakes may develop in the future were identified. The GlabTop2 approach is shown to be a useful tool in hazard management providing data on the potential evolution of future lakes.

The mountains of Central Asia support many environmental functions and ecosystem services. The mountain environments and their services are affected by climate change and climate change adaptation (CCA) actions are required to increase resilience of regional communities. This paper is a systematic review of the English and Russian‐language literature published between 2013 (IPCC AR5) and May 2021 (IPCC AR6) focusing on CCA in the Central Asian mountains. In all, 52 publications have been reviewed. Criteria defining incremental and transformative adaptation were established and the reviewed studies were assigned to one of these approaches. The relatively low number of publications shows that the extent of CCA knowledge represented in academic literature is limited in comparison to other mountainous regions. There is a disparity between the growing body of publications addressing climate change and limited and decreasing number of academic publications focusing on adaptation in the region. Only 11 publications reported transformative adaptation actions. Most of the reviewed papers (55%) focus on water resources and future water availability; 15% focus on land degradation, 10% on changes in vertical zonation of plant species, 7% on loss of plant species, 3% on impacts of hazardous events, and 10% on multiple impacts of climate change. The awareness of the importance of CCA among the regional actors should be improved through closer collaboration between researchers, international organizations focusing on sustainable development and adaptation which have recently become more active in the region, practitioners, and local communities and co‐production of knowledge on the development and implementation of CCA.This article is categorized under: Trans‐Disciplinary Perspectives > Humanities and the Creative Arts Trans‐Disciplinary Perspectives > Humanities and the Creative Arts Vulnerability and Adaptation to Climate Change > Institutions for Adaptation Assessing Impacts of Climate Change > Observed Impacts of Climate Change
