From Arctic, Antarctic, and Alpine Research: “Pollen grains are commonly found in ice cores, particularly those from mountain glaciers at low to middle latitudes … We analyzed major pollen grains in an 87-m-deep ice core drilled at the top of the Grigoriev Ice Cap (4563 m.a.s.l.) in the Tien Shan Mountains, Kyrgyz Republic. Microscopy showed that mainly five pollen taxa were contained in the ice core.”
Glacial meltwater’s influence on biogeochemical cycles in greenland
From Frontiers in Marine Science: “Greenland fjords receive considerable amounts of glacial meltwater discharge from the Greenland Ice Sheet due to present climate warming. This impacts the hydrography, via freshening of the fjord waters, and biological processes due to altered nutrient input and the addition of silts … Our results imply that glacially influenced parts of Greenland’s fjords can be considered as hotspots of carbon export to depth. In a warming climate, this export is likely to be enhanced during glacial melting.”
From Environmental Science and Policy: “Incoherent institutional regimes are among the most critical barriers to adapt water governance under climate change. However, it remains unclear how different governance processes can coordinate competing resource uses despite incoherence of institutional resource regimes. This paper examines how institutional resource regimes and polycentric governance processes are co-evolving and to what extent these processes coordinate competing resource uses in incoherent resource regimes. ”
From Geomorphology: “The identification of different ice flow configurations, evidence of subglacial water and past ice margin collapse indicates a dynamic ice sheet margin with varying glacial conditions and retreat modes. We observe that some of the described morphological associations are similar to those found in the Amundsen sea sector of the West Antarctic Ice Sheet (WAIS) where they are associated with ice sheet and ice stream collapse. Although further studies are needed to assess the precise timing and rates of the glacial processes involved, we conclude that there is enough evidence to support the hypothesis that the EAIS margin can behave as dynamically as the WAIS margin, especially during glacial retreat and ice sheet margin collapse.”

Environmental Impacts of Mining in Glacier Regions
From the Leibniz Institute for East and Southeast European Studies: “The ugly side of Kumtor is that an open-cast mine in pristine mountain conditions is bound to have negative environmental consequences. Combined with global climate change, the threat to glaciers and to sustainable water supplies downstream is severe. Kumtor’s owners and managers are aware of the issue; the questions are to what extent is the company responsible for countering environmental damage and what is the role of the government in protecting the environment?”

Preparing for Glacier Lake Outburst Floods in India
From Environmental Science and Policy: “Over recent years, at the level of international climate science and policy, there has been a shift in the conceptualization of vulnerability toward emergence of ‘climate risk’ as a central concept. Despite this shift, few studies have operationalized these latest concepts to deliver assessment results at local, national, or regional scales, and clarity is lacking. Drawing from a pilot study conducted in the Indian Himalayas we demonstrate how core components of hazard, vulnerability, and exposure have been integrated to assess flood risk at two different scales, and critically discuss how these results have fed into adaptation planning.”

In the following months, Kazakhstan will start the implementation of a Central Asian Regional Glaciological Center. The center was established after the president of the Republic of Kazakhstan, Nursultan Nazarbayev, ratified an agreement last March between his country and the United Nations Educational, Scientific and Cultural Organization (UNESCO).
The Central Asian Regional Glaciological Center will be located in Almaty, the largest city in the country, and has the objective to both contribute to the research of glaciology and improve the scientific understanding of the impacts of climate change on glaciers and the water cycle in the region. As stated by UNESCO, the center will improve coordination of research projects and information sharing between regional institutions currently working on glaciers. Moreover, it will aim to increase the capacities of Central Asian specialists in the field of glaciology.
Christian Hergarten, a current research scientist at the Mountain Societies Research Institute at the University of Central Asia, told GlacierHub that he and his colleagues believe the regional research center will create local and regional ownership in terms of environmental data and information generation for Central Asia. “This should help to move glaciers higher on national agendas and render the effects of global warming on glaciers, water flow and storage a political priority in the area,” Hergarten said.
For Ryskeldi Satke, a researcher focused on Central Asia, countries must have more research hubs outside of the one in Kazakhstan for the sake of the whole region. “In my opinion, Tajikistan, Kyrgyz Republic, Uzbekistan, Kazakhstan and Turkmenistan should have scientific collaboration regarding glaciers and water resources. It is a good step for Kazakhstan to develop research capacity and support scientific exploration in the field of glaciology,” he told GlacierHub.
Due to the relative aridity of the region, glacier meltwater is a key water resource for these countries, with glaciers relevant to the future development of the region. Major Central Asian rivers such as the Syr Darya and Amu Darya provide for the livelihoods of the people living in this semi‐arid region, for example, mostly through hydropower generation and irrigation agriculture. Hergarten added, “Many rivers in Central Asia have their sources in the high mountains where snow and glacier melt contribute substantially to runoff generation— between 10 and 30 percent.”
As stated in the draft proposal of the establishment of the center, thawed snow and glacial water in Central Asia is formed in high-mountainous areas. The zone of runoff formation in these locations determines the hydrological regime and provides water resources to the densely populated region. Unfortunately, these territories are not adequately monitored. This situation is responsible for inadequate information on glacier mass dynamics, among other deficiencies. The lack of factual information on processes and natural phenomena at high altitudes in cold mountain regions forces scientists to use secondary data and indirect methods to make assumptions when constructing forecast models. This explains the lack of consensus among scientists on the impact of climate change on the region’s water resources in general and glaciers in particular.
Nazif Shahrani, professor of Anthropology, Central Asian and Middle Eastern Studies at Indiana University, told GlacierHub that it is “critical and necessary” to monitor the global impact of changing ecological conditions and the Aral Sea’s virtual disappearance in the region, especially on the remaining glacier fields in the area. Moreover, the initiative by Kazakhstan, one of the richest and more populous nations in the region, is most welcome and will be beneficial, especially if it includes monitoring the glacier field not just within the boundaries of Kazakhstan but also in the other republics with glaciers, Shahrani noted. “The future viability of all five republics of former Central Asia and Afghanistan will depend on waters from the glaciers and the mountains of this region,” he said.
The dependence of Central Asian countries on mountain resources varies across Central Asia. While countries such as Kyrgyzstan, Tajikistan and Uzbekistan rely heavily and immediately on mountain resources, the importance of mountain resources is less pronounced for Kazakhstan with its vast steppes and grasslands, according to Hergarten. “The Kyrgyz, Tajik and partly also the Uzbek economies depend critically on water originating from Central Asian mountain ranges for agricultural production, benefitting large parts of the population. But the economies also depend on mineral resources originating from mountains,” he said.
The negotiation and development of the agreement dates back to 2006 when Central Asian countries assessed the state of glaciers and water resources of the region during a workshop organized by UNESCO in Kazakhstan. During the meeting, the participants acknowledged the need for a regional center on glacier research. Six years later, an agreement on the establishment of the regional research center was signed in Astana, the capital of the country, during the official visit of the Director-General of UNESCO, Irina Bokova. The Central-Asian Regional Glaciological Center will be implemented under the auspices of UNESCO as a category 2 organization, which indicates that the center is not legally part of the international organization. However, it is associated with it through an agreement between UNESCO and the country that will host the center.
“Kazakhstan is a prominent member of the international community and such status gives the Kazakh government more opportunities to implement or initiate regional cooperation based on the scientific data and research from the hub in Almaty. Regardless of the outcome, the research center is a good and positive sign for the region. Most likely, it will create more room and opportunities for the regional scientists to congregate and exchange scientific data on glaciers and water resources,” Satke concluded.
