Earthquake in Peru Creates Fear of Glacier Floods

Spread the News:ShareAn earthquake in Peru earlier this year produced significant ground shaking in highland regions of the country. It set off a wave of panic that glacial lakes in the Andes might burst their banks and create devastating floods. The quake, of magnitude 5.3 on the Richter scale, took place at 1:42am local time on January 28. As reported by the U.S. Geological Survey’s Earthquake Hazards Program, its epicenter was located under the Pacific Ocean, about 55 kilometers from the port of Chimbote in the region of Ancash, where the shaking was most instance. It was felt up and down the coast, as far north as Trujillo and as far south as Lima. The tremors also extended inland. This earthquake was the first of a cluster. The second occurred five hours later in the town of Ica to the south of Chimbote. The third took place two hours after that, near Arequipa, still further to the south. These were smaller—4.7 and 4.4, respectively—but close enough in time to create a stir in the media, with extensive coverage all day long in national media. Moreover, Peru had experienced mudslides and debris flows in the months before the earthquake, adding to the sense of concern. Sismo de 5,1 se registró este viernes en el sur de Perú https://t.co/tD3ANGnumU #Actualidad #Noticias — Noticias24 Carabobo (@N24_carabobo) January 28, 2017 The first earthquake was a source of great concern in the highland areas closest to Chimbote, particularly in the Callejón de Huaylas—the long valley along the Santa River, just below the Cordillera Blanca, the mountain chain which contains the largest area of glaciers in Peru. The regional capital of Huaraz and several other sizable towns are located in this valley, which has experienced a number of destructive glacier lake outburst floods. Christian Huggel, a Swiss glaciologist who was working in the area at the time, wrote, “We felt the earthquake here in Huaraz during the night.” He added, “I did not see any damage in the morning, so everything seems to be okay around here.” Benjamin Morales, the director of Peru’s National Institute for Research on Glaciers and Mountain Ecosystems, told GlacierHub that “the heavy rainfall and landslides in central and southern regions [of Peru]” added to the concern following the earthquakes, sensitizing the whole country to the risk of natural hazards even though risks were not as severe in Ancash and north of the country, where, he said, “rainfall is lower.” Tony Oliver-Smith, an anthropologist at the University of Florida with extensive experience in the region, indicated to GlacierHub that the timing of the events, in the middle of the rainy season, was significant. He wrote, “Those of us who have worked in the Callejon de Huaylas are always alert to the effects of earthquakes and landslides, particularly in the rainy season,” when soils are moist, and more likely to erode. The greatest fear was in Carhuaz, a provincial capital to the north of Huaraz. It lies near Huascaran, the tallest peak in the Cordillera Blanca, and the site of one of the world’s largest glacier lake outburst floods in 1970. This event, triggered by an earthquake, led to a debris flow which covered the town of Yungay, with about 6,000 fatalities. A series of smaller aftershocks which followed the main earthquake kept the tensions high in Carhuaz. A Peruvian newspaper, Primera Página, reported that people were concerned that “blocks of ice would detach from glaciers and fall into the lake.” The resulting waves could overtop the rock walls that rim the lake and create a flood. The residents of Carhuaz were also aware that the town...

BREAKING: Ryan Zinke Confirmed as Interior Secretary, Talks Glacier Retreat

Spread the News:ShareIt’s official. The Senate voted today to confirm Rep. Ryan Zinke (R–MT) as the nation’s next Secretary of the Interior. The strong majority confirmation vote of 68-31 gives Zinke, a Westerner and fourth–generation Montanan, commanding power over the nation’s most prized public lands and wildlife as well as 70,000 employees, 280,000 volunteers, and a $12 billion annual budget. The Department of the Interior— a Cabinet-level agency created in 1849 to manage the country’s internal affairs— oversees such critical offices as the National Park Service, U.S. Fish and Wildlife Service, the Bureau of Indian Affairs, and the U.S. Geological Survey, among others. A former boy scout turned Navy SEAL in the Iraq desert, Zinke grew up 30 minutes outside of Glacier National Park in Montana, an experience he cites as the impetus for his interest and dedication to environmental stewardship. He has promised to “restore trust” in the department and address the $12-billion maintenance backlog in America’s national parks from Alaska to the beaches of Maine. Republicans hope Zinke will also usher in a “culture of change” to the Interior by repealing many of the Obama administration’s land management policies seen to favor environmentalists over local interests. Zinke, a Trump administration favorite, was once considered a moderate Republican when it came to environmental and land management issues, siding with Democrats on bipartisan legislation and standing up to fellow Republicans on conservation principles. He challenged Republican colleagues on the transfer of federal lands to the states, for example, speaking out and voting against certain Republican-led proposals. In 2016, he also supported Democrats in calling for full funding and permanent authorization for the Land and Water Conservation Fund in a bipartisan effort. Most recently, in July 2016, Zinke publicly withdrew from the Republican Convention due to the party’s support of federal land transfers to the states. At the same time, Zinke is a vocal advocate for oil and gas development on public lands, fracking and coal mining interests, and weaker protection for endangered species and national monuments, among other anti-environmental platforms, earning him a five percent rating from the League of Conservation Voters and an F rating from the National Parks Action Fund. His recent statements, particularly on the issue of climate change, have some scientists and environmentalists deeply concerned. On the topic, Zinke openly oscillates between acceptance and denial, both of which he displayed during his confirmation hearing before the U.S. Senate Committee on Energy and Natural Resources in January. However, unlike President Trump, who flat out denies climate change, Zinke went on record during the hearing citing glacier retreat as evidence that the planet is warming in a heated exchange with Senator Bernie Sanders (I-VT). Sanders was the first to challenge Zinke on the issue during the hearing. “Climate change is very important to issues that the Department of the Interior deals with,” said Sanders. “Is President-elect Trump right? Is climate change a hoax?” Zinke seemed to have a response prepared for the question, launching into a multi-part answer on what he called the “tenants” of his climate change perspective. These include: one, his recognition that climate is changing, and two, his belief that man is an influence. “That is indisputable,” Zinke said, adding later, “I do not believe it is a hoax.” Zinke offered Glacier National Park as an example of a visible symptom of climate change that he has witnessed personally. “I have seen glaciers over the period of my time recede. As a matter of fact, when my family and I have eaten lunch on Grinnell Glacier, the glacier has receded during lunch,” Zinke said. This comment prompted chiding...

New Report Documents Pakistan’s Water Insecurity

New Report Documents Pakistan’s Water Insecurity

Spread the News:ShareWater security is a pervasive issue in Pakistan, a largely arid country. The majority of the country receives less than 300mm of rain per year, while a small region in the north receives upwards of 1000 mm per year. The Indus River provides much of the water to the area, but its flow is irregular due to the variable precipitation. Moreover, the river originates partly in Pakistan and partly in India, creating additional political challenges that stem from the decades-long history of tension between the two countries. Last month, the United Nations Development Programme released a Development Advocate Pakistan report that describes the uncertain future of water in Pakistan, which is impacted by changing climate and melting glaciers, as well as political issues with neighboring India. The report’s editors suggest several ways to increase water stability in Pakistan. They advise increasing public awareness because the lack of trust stems in part from incomplete access to data and information. They also recommend high efficiency irrigation systems and updating academic curriculum in the country to include sustainable development. As the report describes, the region of Gilgit-Baltistan in northern Pakistan provides most of the water in the glaciated parts of the country. Altitudes exceed 5000 meters with annual snowfall of approximately 5000 millimeters in the highest regions. This zone is the largest area of perennial glaciers outside the polar regions; nearly one third of the Gilgit-Baltistan area is glaciated. The meltwater of these glaciers contribute a massive volume of freshwater, which forms a significant component of the flow into the Indus River. The variability of river flows as a result of monsoon seasons has led to water crises and conflicts between provinces, as well as neighboring countries. The Indus Water Treaty has allowed for peaceful relations between Pakistan and its neighbor India for the past 40 years. As Justin Rowlatt describes in his BBC report from September 2016, the Indus Water Treaty has survived two wars and numerous military impasses between the two countries. However, the increased water stress in the Indus River basin since the early 1990s has strained the treaty.  Coverage of the UNDP report in Indian and Pakistani newspapers has unsurprisingly varied. A recent article in the Times of India covering the report emphasized Pakistan’s negligence and delays in presenting cases to the Indus Water Treaty. An article in the Hindustan Times reports that, “Pakistan has cleverly employed the IWT to have its cake and eat it too” by receiving the larger amount of water the treaty allots for downstream States, while also using the treaty to sustain conflict with India. The coverage of the issue by Pakistani newspapers is sparser. In one editorial published in Pakistan Today, the author calls the UNDP report a “wake-up call” and urges cooperation between Pakistan and India to resolve the dispute. The treaty itself fails to address two important issues. The first is that it does not provide for a division of water during shortages in the dry years between India and Pakistan. The second is that it does not discuss the cumulative impact of reservoirs on the flows of the Chenab River, a major tributary of the Indus, into Pakistan. On a fundamental level, the government of Pakistan does not think the Indus Water Treaty is effective because its people are not satisfied with the amount of water received, but the government of India does not wish to amend the treaty or address water conflict between the countries in other contexts. The treaty allows India to create reservoirs on nearby rivers to store water for hydropower and flood shortages. This provision has created conflicts between...

Flood Early Warning Systems Leave Women Vulnerable

Flood Early Warning Systems Leave Women Vulnerable

Spread the News:ShareGlacier lake outburst floods (GLOFs) pose an immediate threat to locations in mountain regions where rising temperatures contribute to glacier melt. This risk makes it crucial that communities at risk to GLOFs develop early warning systems (EWS) to alert residents of impending danger. In order for EWS to be effective, gender needs to be prioritized. In a recent paper published by the International Center for Integrated Mountain Development (ICIMOD), Mandira Shrestha et al. evaluated flood early warning systems in Bhutan and found that many EWS exclude women, who are especially susceptible to natural disasters like GLOFs. GLOFs, which are difficult to predict and devastating to local populations, occur when meltwater is suddenly released from a lake just below a glacier. When this occurs, large amounts of water rush down valleys, picking up debris. They can lead to many deaths and to extensive destruction of fields and property.   In total, Bhutan has 24 lakes which are capable of causing GLOFs.  As temperatures rise, glacier melt increases, leading to exposed moraines and larger volumes of water. However, an EWS can help save lives during a GLOF, especially if it is combined with preparatory actions before a flood occurs. In Bhutan, the EWS was first introduced in 1988 as part of the Hindu Kush Himalayan – Hydrological Cycle Observing System (HKH-HYCOS), a project developed by ICIMOD, national governments in the region, and the World Meteorological Organization. However, Shrestha et al. found that none of the current policies in Bhutan’s EWS address specific needs and experiences of women during natural disasters. In planning documents, women are described as victims, rather than presented as playing an important role in disaster risk management. The Bhutan EWS contains four major elements, also found in other warning systems: risk assessment, monitoring and warning, dissemination and communication, and response capability. The Bhutanese government first prioritized flood early warning systems in 1994, following a detrimental GLOF, which killed 12 people, destroyed 21 homes, and washed away nearly 2,000 acres of land. Shrestha et al. point out that even a good warning system would not be fully effective in preventing such a tragedy if it fails to reach vulnerable populations like women, as well as other such populations including children, disabled people, and the elderly. As Shrestha et al. explain, while women in Bhutan make up 49% of the population and legally have equal rights and access to education, public services, and health care, most women engage in household labor, while men dominate political work. The authors indicate that only 25 percent of women in Bhutan are involved in non-agricultural work. Extensive male out-migration in Bhutan, as elsewhere in the Hindu Kush Himalayas, leaves women to carry out the work in domestic agriculture. As a result, Bhutanese women are excluded from decision-making processes at community or larger scales. This pattern is reflected in other nearby countries as well.  One study done on disaster-affected people seeking mental health care in Bangladesh, which has the highest natural disaster mortality rate in the world, found that women have higher mortality rates in natural disasters, and are also extremely vulnerable in the aftermath of a natural disaster. For example, they are more likely to face food shortage, sexual harassment, and disease, among other issues. Shrestha et al. describe how the social structure in Bhutan leaves women dependent on men for receiving disaster information, because these details are shared in public places, where women typically do not go. Many of the alerts are done through sirens, but some women cannot hear them as they are located in towns rather than rural areas. Even if women do receive the information, it is...

Uranium Tailings Pose Environmental Risk In Kyrgyzstan

Uranium Tailings Pose Environmental Risk In Kyrgyzstan

Spread the News:ShareA version of this article was published in The Diplomat on December 13, 2016. The remote town of Mailuu Suu in South Kyrgyzstan is known for a Soviet legacy that still haunts the local population of more than 22,000. Residents of Mailuu Suu commonly say that the very first Soviet atomic bomb was made out of locally extracted uranium in the late 1940s. The township is surrounded by uranium tailings and radioactive dumps that have been of greatest concern to the country’s neighbor, Uzbekistan, for decades. The gravest dilemma for the Kyrgyz government is related to the frequent landslides in the areas along the river of Mailuu Suu where the Soviet government kept radioactive waste from the uranium mining. The glaciers of the southern Tian Shan feed this river, which flows directly to the neighboring republic of Uzbekistan in the Ferghana Valley. Previously, an accident in April 1958 at the uranium tailing 7 led to the discharge of  “600,000 cubic meters [of radioactive material] into the river [of Mailuu Suu],” according to an OSCE report in 2005. The demise of the Soviet Union and poor maintenance of the uranium tailings since the 1990s has raised concerns in the region and abroad, ultimately bringing the World Bank’s attention to the challenging task of remediation in Mailuu Suu. The World Bank has invested $11.76 million into the “Disaster Hazard Mitigation” project in Mailuu Suu, which was launched in 2004 and completed in 2012. The World Bank’s objective has been focused on minimizing “the exposure of humans, livestock, and fluvial flora and fauna to radionuclide’s associated with abandoned uranium mine tailings and waste rock dumps in the Mailuu-Suu area; and improvement of the effectiveness of emergency management and response by national and sub-national authorities and local communities to disaster situations.” However, locals who are weary of impact from the uranium legacy believe health issues and birth anomalies persist in the area. “[There are] big problems in this town,” said Minabar Umarova, chair of the Women’s Committee of Mailuu Suu. “Our analysis in 2014 of health among local women and children in Mailuu Suu revealed that our town of 24,000 had 180 children [younger than 18] with disabilities. At the same time, the neighboring district of Suzak with more than 240,000 residents had only 165 disabled children. So, Suzak district, with the population ten times larger than Mailuu Suu, has less children with disabilities.” Indeed, an “effect of radiation and radionuclides on public health in Mailuu Suu has reflected on higher rates of birth anomalies — 5.12 percent; miscarriages — 12.1 percent; stillbirth rate — 1.25 percent” than anywhere else in the country, according to research by the Institute of Medical Problems of the National Academy of Sciences, Kyrgyz Republic. The Institute’s previous field monitoring and observation in 2007 found the presence of radioactive uranium and thorium in women’s placentas in Mailuu Suu and surrounding villages. Respectively, in the village of Sary Bae, background gamma radiation was recorded within 40  – 640 mR/h [milliroentgens per hour] whereas in the neighboring city of Jalal Abad background radiation is 21 mR/h, according to official data. Sampling of the 15 local women’s placentas has shown the presence of uranium in the amount of 0.33 mg/kg ± 0.2 (p <0.05); and thorium in the amount of 0.25 mg/kg ± 0.1 (p <0.05). Uranium and thorium in women’s placenta was a cause for complications during pregnancy in 80 percent of the cases among observed women of Mailuu Suu. The Institute for Medical Studies’ research has concluded that snow melt and flash floods trigger frequent mudslides during the spring season in Mailuu Suu that in effect carry radionuclides...

Ice-Spy: Declassified Satellite Images Measure Glacial Loss

Spread the News:ShareSince the 1960s, images from spy satellites have been replacing the use of planes for reconnaissance intelligence missions. Making the transition from planes to satellites was prompted by an infamous U-2 incident during the Cold War when U.S. pilot Francis Gary Powers’ U-2 spy plane was shot down in Soviet air space. Five days later, after considerable embarrassment and controversy, President Eisenhower approved the first launch of an intelligence satellite, part of a new scientific electronic intelligence system termed ELINT. Today, declassified images from satellites have resurfaced to support scientific research on glaciers and climate change. Scientists from Columbia University and the University of Utah created 3-D images of glaciers across the Himalayas, and Bhutan specifically, by using satellite imagery to track glacial retreat related to climate change. Joshua Maurer et al. published the results of their Bhutan study in The Cryosphere to help fill in the gaps of “a severe lack of field data” for Eastern Himalayan glaciers. Being able to understand and quantify ice loss trends in isolated mountain areas like Bhutan requires physical measurements that are currently not available due to complex politics and rugged terrain. Luckily, the scientists found an alternative route to reach their measurement goals by comparing declassified spy satellite images from 1974 with images taken in 2006 using the ASTER, Advanced Spaceborne Thermal Emission and Reflection Radiometer, a spaceborne imaging instrument aboard NASA’s earth-observing Terra satellite. Bhutan has hundreds of glaciers and glacial lakes. Physical data collection can be a daunting process in such a region considering the vast quantity of glaciers in combination with freezing weather conditions and high winds. The lead researcher of the Bhutan study, Joshua Maurer from Columbia University, experienced firsthand the logistical challenges associated with directly measuring changes in glacial ice density when conducting research on glacial change in the remote and high-altitude regions of Bhutan. Inspired by this difficult experience, Maurer collaborated with other scientists from the University of Utah to find alternative methods for quantifying trends in glacial ice density. Maurer and the team of researchers devised a strategy to use declassified satellite images to collect data by a process of photogrammetry, the use of photographs to survey and measure distances. More than 800,000 images from the CORONA Satellite program, taken in the 1970s and 1980s, have been sent to the U.S. Geological Survey from the Central Intelligence Agency (CIA), and made available to the public. Several advanced mathematical tools are necessary for making measurements from raw image files. For this particular study, the team used the declassified photos from the 1970s to track changes in glacial ice coverage over time when compared to more recent images from the Hexagon Imagery Program database taken by the Swiss-based Leica Geosystems’ airborne sensors in 2006. Once a timeline was created from the pictures, measurements were made using NASA’s space tool ASTER. This method, Maurer argues, is the solution for measuring massive amounts of hard-to-access data. But making precise measurements integrating several sets of images from different periods of time is no simple task. Pixel blocks, minute areas of illuminations from which images are composed, were processed to correspond with regions designated on the film. The blocks of pixels were then selected to maximize coverage of glaciers and avoid regions with cloud cover. Computer-generated algorithms transform these blocks of image into measurements using automated point detectors and descriptors. Images from the declassified satellite database may suffer from a lack of clarity, so it was also important for the researchers to address these issues. For example, debris-covered glaciers are difficult to distinguish from surrounding terrain using visible imagery...
