Surviving in Antarctic conditions takes more than cold-resilience for bacteria, recent research from the Center for Cellular and Molecular Biology found.

Using six different stressors in lab conditions, from temperature stress to pH change stress to salt and oxidative stress, the researchers were able to test bacterial resistance in the environments they are likely to encounter in Antarctica. In Antarctic glaciers, bacteria are likely to experience extreme cold, in thermal vents extreme heat, and in dried up lakes high levels of salinity. Often, bacteria experience more than one stress factor at a time.

Tests were carried out on ten different bacteria strains, which were grown separately and exposed to different conditions. A number of mutant bacteria developed from a strain of Pseudomonas syringae Lz4w, were also tested so that researchers could identify some of the genetic factors that allowed bacteria to develop stress resilience.

Researchers found that of all the stress conditions, the bacteria strains were better able to tolerate alkaline conditions. The bacteria did not fare so well under acidic conditions, which bacteria can face in Antarctic glaciers that contain some mineral acids.

Other stress tolerance levels varied depending on the bacteria strain. For example, Arthrobacter kerguelensis survived oxidation stress better than Pseudomonas meridiana. Under Ultra-Violet radiation, most of the bacteria strains died.

“Our investigation on tolerance of cold-adapted Antarctic bacteria to other environmental stressors fills the void in the present state of knowledge on the stress-adaptability of Antarctic bacteria,” the authors wrote. “The alkali-tolerance of all of the cold-tolerant Antarctic strains reveals their similarity with some other cold-tolerant bacteria isolated some time back from the Himalayan glacier.”

Researchers also found that bacteria that were exposed to multiple stress factors developed multi-stress protective molecules from proteins, lipids or other types of molecules which allowed them to be more resilient.

By looking into some of these proteins, the researchers were able to begin developing an understanding of the genetic elements that allowed bacteria to develop a tolerance for multiple stressful conditions. The findings could provide insights in the development of resilient  bacteria strains through genetic engineering.

“The multistress-protective potential of a metabolic enzyme, as evidenced in this study, reveals intricacy in the mechanism involved in stress adaptation of bacteria,” the authors concluded.

After the devastating earthquakes in Nepal earlier this year, Sienna Craig began to conduct field research in Mustang to understand how communities in the area perceived and dealt with the earthquake. Craig is Associate Professor and Chair of the Department of Anthropology at Dartmouth College. She is the co-editor of HIMALAYA, the flagship journal of the Association for Nepal and Himalayan Studies, and the co-founder of DROKPA, a nonprofit organization dedicated to partnering with pastoral communities in the greater Himalayan region to implement grassroots development and promote social entrepreneurship. She agreed to write a post for GlacierHub about her work.

Yangjin and I were talking about causality when the topic of glaciers came up. She was describing the interviews she and her fellow community researchers from Mustang, Nepal, had completed this summer as part of an NSF RAPID award called “Narrating Disaster: Calibrating Causality and Response to the 2015 Earthquakes in Nepal.” Yangjin moved her hands and shoulders, narrating, through the words of others, how this living earth, jigten, balances on the back of a mythical animal. Sometimes it is an elephant, other times a white ox, fish, tortoise, or pig. “When the animal shakes its tail, there is a small earthquake. This time people felt the whole body shaking.”

This causal explanation of Nepal’s devastating earthquakes will likely prove to be a common response in our research, particularly among the elderly. Other recurring explanations include discussions of the four elements – fire, water, air, and earth – which at once comprise and course through our planet. When these elements are out of balance or in need of release, events such as earthquakes, floods, or volcanic eruptions occur, locals explained. These views resonate with Tibetan Buddhist cosmological understandings as well as those derived from the region’s medical and astrological traditions. Even so, we are finding that such concepts are often voiced in dialogue with what our interlocutors recognize as “science,” including descriptions of tectonic plates shifting and colloquial expressions that correspond with geological and geophysical concepts.

“Many people also spoke about the cultural and religious reasons for the earthquakes,” Yangjin continued. These reasons might be thought of as the lived effects of the anthropocene in culturally Himalayan terms.

“Some people said these days people are more greedy or focused on individual concerns. Others are poor or ignorant of religion so they use nature’s resources without making proper ritual.” In this ‘dark era’ (kali yug), Yangjin said, reflecting the views of others, we are not using the earth carefully. She went on to describe how people mentioned that specific deities of place (lü, tsen, sabdak, etc.) were displeased with the ways people have forgotten to honor them. At times this reflected a shift in Mustang away from subsistence agriculture toward planting cash crops. “One person in [the village of] Samar said that since so many people are now just planting apples, and nothing else, the lü [serpent spirits] are not happy.” In such terms, the earthquakes are being interpreted as painful reminders to pay attention – wakeup calls that have, in some instances, sparked new waves of religious action among young and old alike.

“The earthquakes have also made people very scared of floods,” Yangjin went on. “Especially in some areas where there are glaciers.” Yangjin is from the Village Development Committee of Tshoshar, a region that suffered massive destruction in the wake of a glacial lake outburst flood about thirty years ago, right around the time Yangjin was born. The results of this flood still define great swaths of Tshoshar’s landscape: river stones the size of ostrich eggs and massive boulders stretch across the river valley, lending it a lunar feel. I had known about this flood but had not realized that a relatively mild earthquake may have triggered it. Such connections are now being made – memories form and re-form as people reflect on the past as a way of dealing with the present and auguring uncertain futures.

Yangjin then explained that a youth group from Kimaling, one of Tshonup’s hamlets, had organized an expedition up to Gyakar Tsho, a glacial lake tucked into the folds of Mustang’s trans-Himalayan ridges. “Youth from all of the nine wards [in Tshonup VDC] went up to the glacier to look at it, but also to take care of it.”

“What do you mean ‘take care of it’?” I asked.

“They collected all sorts of chinlab [objects ritually imbued with efficacy] that had come from many holy places or from important lamas. They went up and put it on the glacier to keep it happy, to keep it in place.” Later that day I watched video footage of this event: young men moving across moraine, laughing and narrating their adventure. The footage did not show them making chinlab offerings, but several other interviews confirmed they had indeed made such propitiations.

“Sakya Trizin Rinpoche said that people didn’t have to make such offerings to the glacier,” Yangjin went on, “but local people felt it was important. So they did it anyway.” I found this admission fascinating. At a moment when religious affiliation across the high Himalaya seems to be consolidating around more orthodox manifestations of Tibetan Buddhism such as that embodied by the leader of the Sakya school, experiences of deeply grounded environmental precarity reinforce the importance of place-based knowledge and sacred geography. This glacier – at once a source of much needed irrigation water and a specter of ruin – needs to be coaxed into staying put by those for whom its presence matters most.

The research reflected in this post would not have been possible without Ngawang Tsering Gurung, Yangjin Bista, Tsewang Gyurme Gurung and Karma Chodon Gurung. 

The NSF RAPID Award 1547377 (2015-2017) was granted to PI Kristine Hildebrandt (Southern Illinois University – Edwardsville), Co-PIs Geoff Childs (Washington University – St. Louis), Sienna Craig (Dartmouth College), and Mark Donohue (Australia National University).  This project combines ethnographic and linguistic field methods to study the lived experiences of the 2015 earthquakes in three contiguous but differently impacted districts: Mustang, Manang, and Gorkha. 


Mt. McKinley’s Name Changed Back to Denali

United States President Barack Obama announced this week he would officially change the name of Mount McKinley, North America’s tallest peak, back to Denali, the original Native American name for the mountain.

Mount McKinley was named after Republican President William McKinley more than a century ago, but the name Denali has older roots in the language of the Athabascan people of Alaska. The name means “the high one,” or “the great one.” Denali’s summit reaches 5,500 metres and is covered by five large glaciers.

Disputes over the mountain’s name began in the 1970’s when the Alaskan legislature requested that the mountain’s official name be changed back to Denali. A stalemate was reached in 1980, when, as a compromise, McKinley National Park was renamed Denali National Park and Preserve, but the mountain’s name remained unchanged. Now, 40 years later, the renaming remains controversial. Though many Alaskans celebrate the name change, politicians from Ohio — President McKinley’s home state — are not happy. In a tweet, Ohio Governor John Kasich said Obama had “overstepped his bounds.”

In defense of Obama’s decision, Interior Secretary Sally Jewell said President McKinley had never visited Alaska, adding that the deceased president had no connection to the mountain. Native Americans across the country have applauded the decision.

“Yes, we are truly excited about it- it’s a long time coming since Alaskans have wanted the change for  a long time,” Malinda Chase, from the Association of Interior Native Educators, told GlacierHub. “On the home front, it’s a definite celebration for our People, our Languages, and the ever-present guiding strength of our Ancestors, whom I’m sure will be celebrating in all their glory in the early morning sunlight shining on the high and stunning peaks of our wondrous Denali!”

Other major glaciated peaks have also had their indigenous names restored. Kilimanjaro, the highest peak in East Africa, had a German name, Kaiser-Wilhelm-Spitze (Emperor William Peak) from 1889 to 1918, the date at the end of World War I when German East Africa became the British colony of Tanganyika, though some Germans kept using the name until 1964, when the colony, together with the island of Zanzibar, became the independent country of Tanzania. Ernest Hemingway’s famous short story, “The Snows of Kilimanjaro,” first published in Esquire Magazine in 1936, may have contributed to removing any lingering attachment to the mountain’s German, rather than its KiSwahili, name.

Commemorative New Zealand dollar (source: NZ Post)

New Zealand’s highest peak, Mount Cook, was given a double name in 1998, Aoroki/Mount Cook, placing the indigenous  Maori  name first.  This decision came after some decades of negotiation, in which the indigenous groups of southern New Zealand pressed their land claims under nineteenth century treaties. A commemorative non-circulating dollar coin was issued some years later.

And some mountains have names which remain unresolved. Mount Everest is known as Sagarmatha in Nepali and Chomolungma in Tibetan, and many have pressed to eliminate the colonial name. The highest peak in Tajikistan seems unlikely to retain its principal Soviet name, Pik Kommunizma, or its alternate Soviet name, Mount Stalin, but several others names are in use, including  Garmo and Ismoil Somoni, the latter being a leader of a 9th and 10th century dynasty in the region. The complex topography and difficult access of the Pamir Range contribute to the multiplicity of names which individual mountains receive.  

Nonetheless, a number of glacier-covered mountains around the world continue to be internationally known by the name given by colonial explorers. It seems likely that they will join Denali and Kilimanjaro in shaking off their colonial names–names used, it must be remembered, for only a small fraction of the history of human settlement in these mountains, or, at least, like Aoraki/Mount Cook, their double, hybrid status could be acknowledged.

Tracking Glaciers & Rivers in Bhutan

Less than a decade back Bhutan transitioned from an absolute monarchy to a democracy. Although right to information was enshrined in their constitution, availing reports and info concerning glaciers, health of rivers and status of hydropower projects remains a challenge to this day. Most government reports are neither published, nor readily uploaded on to websites, and therefore seldom available for public consumption. Keeping this in mind, we at the South Asia program of International Rivers, a nonprofit, compiled ‘Bhutan Rivers Watch’, a one-stop repository of blogs, reports, analysis and latest news from the Himalayan kingdom.

Bhutan, a global hot spot of hydropower development, has 76 identified dam sites with a potential to generate 23,760-megawatts. Most of these projects are in the planning stage, while Bhutan looks to expedite undertakings that will take them towards the 10,000-megawatt mark in the next decade. These interventions will make significant changes in the riverine and physical environment.

Bhutanese rivers are glacier fed, and it is estimated that glaciers cover approximately 1,300 square kilometers of sovereign territory. The Government has been tracking changes in climate by monitoring precipitation, glacial melt, and the changing hydrology of the main river basins. At a meeting organized by International Rivers in Bhutan last year, we learned from officials that glaciers are receding 20-30 meters each year, and in some cases there has been a 75-cm thinning of the ice sheet. But what is most worrisome for the scientific community, and decision makers, is the occurrence of glacial lake outburst floods.

In the mid 1980’s Bhutan and India conducted joint surveys of glaciers and glacial lakes and concluded that there

was no danger to downstream communities. But sadly a glacial lake outburst killed more than 20 people in October 1994, as a raging wall of water wreaked havoc in the upper reaches of the Punatsangchhu River basin. Since then many field studies have been conducted, and the government of Bhutan has been monitoring the glaciers and glacial lakes to ascertain potential impacts on hydropower dams as well as communities living near the river. We now know that more than 20 outburst floods have occurred in the past two hundred years.

According to a 2012 conference held in Thimphu, the nation’s capital, 25 glacial lakes have been identified as ticking time bombs and potentially dangerous. Given the remote locations, officials of the government of Bhutan travel often 3 days by foot to monitor these glacial lakes. These floods could cause dam breaks, which would be catastrophic not just in Bhutan, but also more than a hundred kilometers downstream in India.

We know it is important to keep people in the loop regarding decisions that impact river health and public safety. This lies at the heart of our efforts, and we’ve dedicated an entire page to tracking planned, under construction and commissioned hydropower projects in Bhutan. To view the latest status of projects, click here.

The seventh article of the Bhutanese Constitution declares: “A Bhutanese citizen shall have the right to information”. Yet, impact assessment studies, for instance, aren’t available in public domain, and as a result there is little public debate and scrutiny on how climate change, receding glaciers and glacial lakes can impact infrastructure such as dams and hydropower projects. This is because of supporting clauses in the constitution that state: “All persons in Bhutan shall have the right to initiate appropriate proceedings in the Supreme Court or High Court for the enforcement of the rights conferred by this Article, subject to section 22 of this Article and procedures prescribed by law.” This section establishes notions of sovereignty, security, unity, integrity, and peace as justifiable reasons for non-disclosure of information.

How hydropower projects will impact downstream riverine communities, besides land and aquatic biodiversity, are of national importance. The ‘Bhutan Rivers Watch’ page is an attempt to compile related information, which we intend to update periodically.

Cracked: Life as a Musher on Alaskan Glaciers

Blair Braverman had a tough job. For two years, between May and September she lived on a glacier the size of Rhode Island where her role was to give tourists the perfect Alaskan experience.

But beneath the facade, life was a challenge.

“Nothing was meant to live on the glacier, and the longer I stayed there, the clearer this became,” she wrote in a piece for the Atavist.

The landscape was always shifting – some mornings Braverman would wake up and a lake would have formed overnight. By the next day, the lake would be gone. Other days, surface snow would melt away around her tent.

Keeping the site, which hosted 200 huskies, nine mushers and other staff, clean was also a challenge. Dog hairs had to be raked off the snow and dog poop picked up as soon as it dropped. Teams would regularly go out and poke holes in the snow, searching for potential crevices that could bring rapid death.

Mushers and staff could feel the toll on their bodies. Sunlight reflecting off the snow would burn their nostrils and hurt their eyes. On rainy weeks, Braverman said her skin would peel off in long white strips.

Still, Braverman and her colleagues adjusted to the lifestyle, delivering smiles and an abundance  of wonderful memories to tourists.

Wonderful, that is, until heavy storms trapped a group of tourists for days on a glacier, a tale Braverman recounted for This American Life. What followed was almost two days of pretending life on a glacier was paradise while keeping the tourists calm. A longer account can be read on the Atavist.

Braverman is now working on a book, tentatively called ‘Welcome to the Goddamn Ice Cube.’  She agreed to talk to GlacierHub about her experiences and her upcoming work.

GH: What drew you to working on a glacier?

BB: I had spent the previous year learning to dogsled at a Norwegian folk school. Working on the glacier seemed like an adventure, a way to make some money and keep running dogs during the summer months.


GH: Why do you think it is important to share your story?

BB: People talk a lot about the sustainability of this kind of glacier-dogsledding operation, but of course, there are several kinds of sustainability. The company went to great lengths to practice Leave No Trace, whether that meant raking dog hair off the snow or covering everything with white tarps so that the camp was less appealing to birds. That’s one kind of sustainability, one that has to do with the health of the glacier. As for the health of all glaciers, and of the planet in general—well, obviously all those helicopter flights have a huge carbon footprint. From a larger environmental perspective, that’s devastating. Although I’ll allow some complication there, too, because the tourists who came up were often so moved by the landscape, and found the experience so powerful, that they left—by their own claim—with a renewed commitment to environmental responsibility.

I wrote this story to try to make sense of a third kind of sustainability, which is cultural. What happens when a small group of people live and work together in a remote environment? Why do some people keep coming back, and some feel unable to? How does the experience change if you’re female, or in other ways set apart? What are the possible repercussions of learning to ignore bodily discomfort? I’m interested in how social dynamics play out in extreme landscapes, and this story started, in some sense, as an attempt to answer that question. I think a lot of your readers are grad students and scientists, so maybe some of you face similar concerns during extended field research.

Of course, we weren’t just living on the glacier; we were tour guides, working in the service industry, which only adds more pressure. When you’re all wearing smiles for the customers, tensions between coworkers play out in subtle, more insidious ways.

I also want to add the caveat that my experience at the glacier camp was not necessarily typical—in fact, I hope it wasn’t. A few people can make a big difference in that kind of small community. And when—spoiler alert!—the tourists got stranded, I was impressed overall by how the company handled it. They had extra supplies, they kept everyone safe and calm, and they turned an unprecedented and stressful situation into a relatively pleasant experience.

GH: Can you tell us about the experience of sharing your story on This American Life?

BB: I’ve been working on this story, on and off, for a long time. I wrote the first draft four years ago, and it was fairly long; that draft is closer to how the Atavist version turned out. When I started working with This American Life, we weren’t sure what the theme of the episode would be, so it wasn’t clear from the start which threads would be highlighted. A few weeks later they called back with a theme: Game Face, which I thought was a great fit. So we pared down the story with that in mind.

I’ve never written for radio before, and my producer, Jonathan Menjivar, was really wonderful throughout the whole process. The piece went through about a dozen rounds of edits between him, Joel Lovell, and Ira Glass. Jonathan also coached me through the recording itself, which was totally fun.


GH: Why do you think glaciers capture the imaginations of tourists?

BB: Apart from the obvious (that they’re exotic and spectacular)? Glaciers don’t follow the rules that we’ve come to expect from landscapes. They’re notable not for their life but for their lack of life—and yet they shift and glow and crack, as if they were alive themselves. Also, a lot of meaning has been assigned to them over the years: they’ve symbolized everything from unforgiving might to pristine purity (think ad campaigns for bottled water) to something that’s fragile and in danger, the canary-in-the-coal-mine of climate change.


GH: What do you think people don’t understand about living on glaciers or glaciers in general?

BB: If anything, living on the glacier really impressed upon me how dynamic it was; the landscape felt like it was changing constantly, even when those changes weren’t easily visible. But maybe all landscapes are always changing; maybe it was just my awareness that was different.


GH: Can you tell us a bit about your book?

BB: My book borrows its title from a nickname for the glacier, but it’s mostly about a former-seal-hunting village in the Norwegian Arctic. It tells the story of a changing community through a single local shop. Along the way, I try to explore the experiences that drew me there in the first place.

Roundup: Irrigation, Monitoring, and Tidewater

“Based on three case studies, this paper describes and analyzes the structure and dynamics of irrigation systems in Upper Hunza, located in the western Karakoram, Pakistan. In these deeply incised and arid valleys, glacier and snow melt-water are the primary water sources for agricultural production. The study shows how glacio-fluvial dynamics impact upon irrigation systems and land use practices, and how, in turn, local communities adapt to these changing conditions: framed here as socio-hydrological interactions. A combined methodological approach, including field observations, interviews, mapping and remote sensing analysis, was used to trace historical and recent changes in irrigation networks and land use patterns.”

“The German Research Centre for Geosciences (GFZ, Potsdam, Germany) and the Central-Asian Institute for Applied Geosciences (CAIAG, Bishkek, Kyrgyzstan) jointly established the Global Change Observatory “Gottfried Merzbacher” at the Inylchek Glacier in eastern Kyrgyzstan which is one of the largest non-polar glaciers of the world and consists of two glacier streams. The flow of melt-water from the northern tributary forms a lake (Lake Merzbacher) that is dammed by the calving ice front of the southern Inylchek Glacier. At least once a year a glacial lake outburst flood (GLOF) occurs and the complete water of the Lake Merzbacher drains through sub-glacial channels. To monitor the glacier dynamics including the post-drainage ice dam response, a small network of remotely operated multi-parameter stations (ROMPS) was installed at different locations at the glacier.”

The Largest Non-polar Tidewater Glacier in Alaska

“Hubbard Glacier, located in southeast Alaska, is the world’s largest non-polar tidewater glacier. It has been steadily advancing since it was first mapped in 1895; occasionally, the advance creates an ice or sediment dam that blocks a tributary fjord (Russell Fiord). The sustained advance raises the probability of long-term closure in the near-future, which will strongly impact the ecosystem of Russell Fiord and the nearby community of Yakutat. Here, we examine a 43-year record of flow speeds and terminus position to understand the large-scale dynamics of Hubbard Glacier. Our long-term record shows that the rate of terminus advance has increased slightly since 1895, with the exception of a slowed advance between approximately 1972 and 1984. The short-lived closure events in 1986 and 2002 were not initiated by perturbations in ice velocity or environmental forcings, but were likely due to fluctuations in sedimentation patterns at the terminus.”

Science on Trial at Pascua Lama

Chile’s environmental court ruled on Monday that Pascua Lama, the Andean nation’s most controversial mine, is not responsible for damage done to three glaciers near the mine site.

While the mine’s operations will remain suspended due to a variety of other challenges, the decision was a setback for local environmental groups, who seek to protect the country’s glaciers. Some say it also represents a defeat for Chile’s scientific institutions.

The lawsuit, filed in June 2013, was brought by farming communities in the Alto del Carmen region of northern Chile, who depend on water from the glaciers, together with NGO Latin American Observatory of Environmental Conflicts (OLCA). Alto del Carmen sits in the Huasco Valley, an oasis at the southern end of the Atacama desert, the driest desert in the world. The suit alleged that dust from Pascua Lama, which straddles the border with Argentina, accelerated melt at glaciers in the area, depleting waters that feed into the El Toro river.

In a statement (translated from Spanish), OLCA noted that in its decision, the environmental court ignored scientific documents produced by the state’s own scientists in favor of scientists hired by Canada’s Barrick Gold, the company that operates the mine. Though the court recognized that dust from the mine had settled on the glaciers, it did not accept scientific arguments made in a final state environmental rating resolution on the mine, or RCA, that indicated one millimeter of dust could accelerate melting of the glaciers by as much as 15%. An RCA represents the final outcome of the environmental impact assessment process.

The case seemed to bear out the findings of recent research published in Science and Culture, which suggest that Chilean scientists and scientific institutions have little power in policy debates despite efforts by Chile’s democratic government to build them up over the past decade and a half, post-Pinochet.

“Legally there is this ongoing debate over these resolutions, called RCAs,” said Javiera Barandiaran, assistant professor in global studies at the University of California at Santa Barbara and author of the paper. “How much legal weight do they have vis a vis the law? In the past, there have been challenges, that these resolutions should become the law, the legal standards that the companies are held to. But they say, ‘No, all we’re held to are permits and the country’s laws.’ Because there is no law, it doesn’t matter.”

In mid March, Chilean authorities put forward a proposed framework for a glacier protection law, but it was unclear what specific protections it would offer to glaciers outside Chile’s national parks like the ones affected by Pascua Lama.

Controversy over the Pascua Lama mine is what first put glaciers on the map for Chilean authorities, according to Barandiaran, and launched the debate over the need for laws to protect them.

The Pascua Lama decision inspired a renewed call for strong glacier protection laws from the Chilean branch of global environmental organization Greenpeace.

“If today the environmental court couldn’t credit [the mine] with destruction of the glaciers, having concrete evidence in hand, then we urgently need a law that protects and conserves glaciers,” said Greenpeace Chile director Matias Asun in a statement. He added that Barrick Gold is still charged with glacier damage by Chile’s environmental enforcement agency, the Superintendencia de Medio Ambiente (SMA).

Run by Minera Nevada, the Chilean subsidiary of Canada’s Barrick Gold, Pascua Lama still faces numerous environmental, legal and administrative challenges. Among other things, Barrick is waiting to hear from the SMA about fines that could total over $200 million.

Barrick said the decision confirmed the findings of its own scientists. “Barrick worked with leading independent experts and glaciologists to develop and implement one of the most rigorous glacier monitoring programs anywhere in the world,” said Eduardo Flores, Barrick’s Executive Director for Chile in a statement, available on the company’s website. “We are pleased that the court has confirmed what the technical and scientific evidence demonstrates, that these ice bodies have not been damaged by activities at the Pascua-Lama project.”

The controversy is far from over, but for now Chile’s political and business elites seem to have the upper hand when it comes to competing claims over scientific truth.

According to the 2007 Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC), the decrease of glaciers is a nearly worldwide phenomenon. But how do local communities experience and comprehend melting glaciers?

A range of anthropological studies have examined the relationship between glaciers and societies. While glaciers can be depicted as elements of the landscape and their retreat connected to water excess and scarcity, as demonstrated by Drew (2012) with the case of the Gangotri–Gaumukh Glacier in North India and Cruikshank (2005) with the case of the Mount Saint Elias ranges where Alaska, British Columbia and Yukon Territory meet, glaciers also form part of local worldviews and cultural systems. Therefore, glaciers also provide an entrance point for understanding how environmental change is dealt with by very different societies. Glacial retreat is not only a matter of aesthetics and resource management: changes in the qualities of the landscapes have deeply felt implications for the cultural lives of those living nearby whose material and spiritual lives are entangled with the rhythms of the glaciers. Such unsettled relationships are further disturbed as the melting ice draw in new actors and agendas for either mitigation, adaptation or economic development.

In these encounters around the melting ice there is a friction or tension between Western representations and local people’s views of glaciers. Western science and standards have served as mechanisms to redefine glaciers, valuing them for their aesthetic dimensions, exploiting them for income-generating activities, protecting societies against increasing danger, or using them as scientific laboratories. Thus, the retreating glaciers draw together actors on different scales.   Conceptualizations of glaciers are rich and diversified across cultural settings. In their studies conducted in Nepal, Agrawala & Van Aalst (2008) and Kattelmann (2003) have shown how this must be taken into account when actions for adapting to a changing environment are designed.

The knowledge of communities that live in the proximity of the glaciers is fundamentally empirical as the meltwater feed directly into local livelihoods. As their crops are dependent on stream flow for irrigation, farmers in mountain communities are sensitive observers to changes in water availability as demonstrated by Meenawat & Sovacool (2011) in Bhutan and Banerji & Basu (2010) in North India. In addition to this, glaciers can be central to the ways different peoples narrate their place in the world. In other words, glaciers are part of local ontologies and cosmologies, transcending the representational character of landscape. For some communities, because they have a sacred character, these glaciers compel a set of prescribed behaviors, like Byg & Salick (2009) have shown in their research in Tibet and Frömming (2009) in her research on Mount Kilimanjaro. Transgressing local rules is seen as a key factor in triggering the movement of glaciers and, consequently, the movements of glaciers are often seen as the result of an encounter between different worlds and different values: as local worlds are disrupted by outside influences, glaciers move and may generate natural hazards.

These encounters mean that glaciers are infused with new meanings that may well interfere with how they are valued in local cosmologies. As Purdie (2013) has demonstrated in her study in New Zealand, tourism, for example, has transformed glaciers into sites of great economic importance. But the proximity to the glaciers so valued among tourists contrasts with local taboos that prevail among many societies that attribute a sacred character to glaciers. The same goes for the new lucrative economic activities that glacier retreat has opened up to in different parts of the world as demonstrated by Carey et al. (2012) in their study in the Andes. For both, greater national and international attention and value is given to glaciers which are associated with economic activities. This in turn has led to a lack of understanding of how local communities ascribe cultural value to the glacier. Along similar lines, there is a more concerted reaction from regional and national decision-makers for adaptation to receding glaciers that generates income than glaciers on which small-scale farmers depend.

A central point in the studies of the relationship between glaciers and societies is that glaciers are never just elements of the natural landscape detached from human societies. Glacial retreat therefore has profound influence not only in economic or aesthetic terms, but also in the ways in which people around the world engage with their environment. Beyond mere indexes of climate change, glacial retreat is about deeply felt changes in cultural and social worlds.

Dam Spill Threats at a Gold Mine in Kyrgyzstan  

In light of the Mount Polley tailings dam spill in British Columbia, Canada, environmental activists in Kyrgyzstan are ringing alarm bells over a possible scenario of a similar outburst at Petrov Lake near the Kumtor gold mine project. At Mount Polley, the tailings dam at a copper and gold mine burst in August last year, spilling 25 million cubic meters of toxic waste into nearby lakes. The British Columbia provincial government appointed a commission to probe into the disaster. The commission has concluded that a “dominant factor in the breach of the Mount Polley tailings dam was a failure in the dam’s foundation”. All the while in Kyrgyzstan, the main concern has been and still is the Kumtor project’s chemical waste tailings pond, managed by Centerra Gold. Coincidentally, the very same engineering firm of record for the Mount Polley dam, AMEC, was hired to investigate the Centerra Gold’s environmental record at Kumtor mine in 2013.

The most worrisome issue at Kumtor has been evolving with the stability of the glacial Petrov Lake, which is situated in direct proximity (7 km) above the tailings pond. The northwestern perimeter of Petrov Lake, where the dam is the narrowest, has become a major cause for concern in the Kyrgyz environmentalist community. The length of this particular section is approximately 30 meters. A Petrov Lake outburst could be expected to wash away the Kumtor tailings. where 60 million tons of cyanide liquid waste has been collected and stored so far. Just as in the case with the design of the Mount Polley dam, Kumtor tailings pond’s flawed feasibility has led to the instability of the dam and to seepage of toxic substances into the groundwater. The first report of the movement of the Kumtor tailings dam was recorded in 1999. And it was found that in the initial stages of the construction, the active layer of relatively unstable alluvial deposits had not been removed from the base of the tailings pond. That has made the remaining loamy interlayers (at depths of 4 to 6 meters) alsovulnerable to instability. The Prague-based group CEE Bankwatch has indicated that “in spite of measures to stabilize the dam in 2003 and 2006 (so-called shear keys and toe berm), the dam is still continuing to move.”

As this statement suggest, the company’s plans have not solved the issue of the tailings dam stability. An underlying issue is that the plans to store and manage the tailings from Kumtor did not include a hydrogeological study of the chosen location. The storage pond was built on the riverbed of the Arabel creek. It was later discovered that an old bed aquifer remained at a depth of 6.85 meters.  This active bottom (underflow) is contributing to the instability of the tailings dam. Dr. Robert Moran, a hydro-geologist who visited the Kumtor mine in 2012,  said that the tailings dam instability was “enhanced by the relatively high temperatures of the tailings when they come from the process plant (a highly contaminated mix of about 50% solids, 50% liquids), which would increase permafrost melting [in this high-elevation location]. Such deformation and movement of the tailings structure, combined with the partial melting of the permafrost raises concerns about a catastrophic failure of the tailings impoundment — especially if a severe earthquake were to occur [in this seismically-active region].”

Dr. William T. Colgan, a researcher with Geological Survey of Denmark and Greenland, believes that Petrov Lake presents an “additional geotechnical hazard confronting the Kumtor tailings pond”. According to Colgan’s analysis, “glacial moraine and till is often a poorly consolidated material, outburst floods from proglacial lakes due to berm breaches present a non-trivial hazard. Petrov Lake is one of approximately fifteen proglacial lakes in Kyrgyzstan for which the moraine dam has been classified as ‘at risk of rupture’ by previous researchers. The stability of the lake is important for the stability of the Kumtor tailings pond, as an outburst flood could result in failure by over topping of the downstream Kumtor tailings pond. The lake has grown in size from an area of 1.8 to 3.4 km² between 1977 and 2014. In 1957 it was just 0.96 km2 in area. This growth is due to climate change, which has enhanced both the retreat and melt of Petrov Glacier. This multi-decadal growth indicates that the volume of Petrov Lake is not in steady-state (whereby lake inflow is balanced by lake outflow), and thus the forces being exerted on moraine and till berms are likely changing over time.”

The threat of the environmental disaster over Kumtor tailings pond was highlighted at the United States House of Representatives Committee on Foreign Affairs Subcommittee hearing by Dr. Amanda Wooden (Associate Professor of Environmental Politics & Policy, Bucknell University) in November 2014. Wooden’s testimony has indicated that the “changes in the permafrost underneath this extensive tailing pit at the headwaters to the Naryn River and breach threats to Petrov Lake above the tailing pond are concerns that should be monitored”. Moran believes that in the scenario with Kumtor tailings dam failure, it would rapidly release “masses of contaminated water and sediments (the tailings) into the Kumtor river, endangering downstream people, facilities, downstream rivers, and would likely kill much of the mountain trout population and other aquatic organisms. Such a collapse could negatively-impact waters throughout much of the Naryn River basin, which flows into Uzbekistan.”

In sum, the tailings pond at Petrov Lake, with large quantities of toxic substances in an unstable glacial environment, represents a serious threat to the ecosystems and human populations in two countries. The efforts of environmental activists may serve to bring this serious risk to attention within these countries and beyond, pressing for tighter and more effective regulations.

“The fate of the Hindu Kush Himalayan glaciers has been a topic of heated debate due to their rapid melting and retreat. The underlying reason for the debate is the lack of systematic large-scale observations of the extent of glaciers in the region owing to the high altitude, remoteness of the terrain, and extreme climatic conditions. Here we present a remote sensing–based comprehensive assessment of the current status and observed changes in the glacier extent of the Hindu Kush Himalayas. It reveals highly heterogeneous, yet undeniable impacts of climate change.”

“Levels and surface areas of lakes are indicators of climate change and climate variability. Information of the surface extent of all the lakes on the northeastern Tibetan Plateau and its adjacent areas was extracted from Landsat images obtained in the 1970s, the 1990s, around 2000, and 2010 and developed a lake spatial database. The dynamic changes of the number and lake surface area in the past forty years were analyzed. ”

Science vs. politics in Chile

“Chile’s scientific community fractured over how to define credible science. Divisive and decisive issues included the source of funding, ethics, access to resources, and being local. Although some scientists and non-scientists used boundary work to try to affirm the authority of science, no stable map of scientific credibility resulted from these efforts. Chile’s new democracy is more plural than its recent military dictatorship but still lacks adequate spaces in which to negotiate what counts as credible science. These experiences highlight the need to better understand how science fares through regime transitions and what it contributes to emerging democracies.”
