Climate, Economy, Family: Migration in the Bolivian Andes

Spread the News:ShareHigh in the Bolivian Andes, the pace of glacial retreat is accelerating, which may significantly decrease the amount of glacial meltwater available to streams and aquifers critical to farming communities in the region’s river basins. In addition to the long-term threat posed by glacial retreat, these communities are also threatened by economic uncertainty and climatic variability. As a response to livelihood insecurity, many Bolivian farmers choose to migrate, temporarily or permanently, to nearby urban centers. But how exactly are migration decisions understood within these migrant households? In a recent chapter in Global Migration Issues, Regine Brandt and her team interview farmers in two Andean valleys to understand the factors contributing to migration decisions. The research demonstrates that migration has increased in importance as a livelihood strategy and that rural Bolivians consider environmental factors, social ties and economic needs together when making these decisions. To obtain these findings, the team conducted research in the municipality of Palca, a high-altitude rural area where 80 percent of the population lives in extreme poverty. They asked members of migrant farming households in two separate glacier-fed river basins to describe any factors that had influenced temporary or permanent migration decisions. In analyzing their data, the researchers looked to the frequency with which each causal factor was mentioned in each interview. If, for example, climate change was mentioned several times as a factor for a household, but social conflict was only mentioned once, climate change was understood to be of greater importance to that household in making their decision. According to Raoul Kaenzig, one of the article’s co-authors, the impact of glacial retreat on farmers in the Andean highlands is still poorly documented. In the 1980s, Bolivia underwent a severe drought and has since experienced a rise in the frequency of extreme weather events, as well as a shift in rainfall patterns. In response, some peasants changed their agricultural practices, while others began sending individual family members to urban areas. Internal migrants rarely travel beyond their home region and maintain connections to their rural origins, often spending only part of the year in nearby cities, according to the study. In Bolivia, migration is seen as a means of contributing to the greater household economy— an individual may migrate to find work but with the intention of helping to support the family back home. In an interview with GlacierHub, Corinne Valdivia, a professor of agricultural economics at the University of Missouri, explained how the threats posed to farmers in this and surrounding regions have increased in recent years. “The production risks have increased in the region of the North and Central Altiplano of Bolivia, as well as in Southern Peru, with longer periods without rainfall, and short and intense rains,” she said. “Pests and diseases have also increased. These threaten the livelihoods of families who are producing for their consumption and for the market. Migration is a strategy to address this, but in turn means that less labor is available to tackle the stresses posed by the changing climate.” For 60 percent of the regional migrants interviewed in the study, better educational opportunities were the primary driver of their migration decision. Additionally, nearly every respondent pointed to an increasingly unpredictable climate as a factor in their migration. Individuals living near the Illimani glacier, which has become a symbol of climate change in Bolivia, were significantly more likely to emphasize climatic variability, glacier retreat and water problems as factors in their migration than those living near a less iconic symbol of glacial melting, Mururata. The authors attribute this difference to a combination of observable environmental change and discourse. Unsurprisingly, off-farm...

Elderly Wisdom and Youth Action in Ladakh

Spread the News:SharePeople of Indo-Aryan and Tibetan descent live in one of the highest locations in the world, the Ladakh region of northwestern India. Ladakh extends over 45,000 square miles and includes the Ladakh mountain range, which is part of the glaciated Karakoram Range of south-central Asia. Many in the Ladakh region are Buddhist and believe in good moral conduct such as generosity, righteousness and meditation. This goodwill extends to the glaciers, which they respect and value. The Global Workshop, a project that allows students to create original work that thinks critically about science and development, recently created a video in which young people from Ladakh interview their elders about climate change and its impacts on the glaciers. In the video, the grandparents remember a time during the mid-20th century when streams were full, glaciers were more robust, and snowfall was heavy. Now, farms in the agricultural areas are suffering because of a decrease in glacier meltwater for crop production. “Himalayan Elders on Climate Change” (Source: The Global Workshop/YouTube). In a paper titled “Glaciers and Society,” Karine Gagné, a postdoctoral associate of cultural anthropology at Yale University, and her colleagues, discuss some of the approaches used by locals to counter the impacts of receding glaciers. Gagné spent a fair amount of time working in Ladakh observing everyday life and climatic changes. She told GlacierHub that in certain communities in the region, people depend on specific glaciers, have named them accordingly, and undertake specific actions to protect them. In the paper, Gagné et al. discuss Chewang Norphel, a retired civil engineer in Ladakh who created artificial glaciers to harvest snowmelt and rainwater. Norphel’s project brought attention to the plight of farmers who use meltwater for agriculture. It has since been replicated by the younger generation.   Still, receding glaciers have translated into water scarcity in some Ladakhi villages. Water is a pressing issue because villagers rely on snowfall in the spring to sow their crops. Elders have prayed to mountain deities that their glaciers will provide water in the spring.  Gagné explained that glaciers are “embedded in the local culture and religious views.” People believe, for example, that there is a guardian deity that inhabits the surrounding glaciers and that one’s actions can reflect in the condition of the natural environment. If one behaves unethically, it could lead to less meltwater than is necessary for growing crops that year. Using the information provided by their elders, the youth interviewers from The Global Workshop are documenting the changes in their environment and their elder’s responses. Their interviews will help to fill gaps in environmental data extending to the 1950s in an effort to better understand changes in the local water systems and health of the glaciers.  Many of the youth attend schools like the Students’ Educational and Cultural Movement of Ladakh (SECMOL) environmental school. Founded by education reformist and engineer Sonam Wangchuk, SECMOL works on renewable energy and climate change preparedness with the youth from Ladakh. The campus is a student-run, solar-powered eco-village, where students live among staff and volunteers. The Global Workshop’s video shows the importance of passing down generational knowledge, demonstrating how helpful it can be for youth involvement, community building, and environmental data collection.

The Messy Encounter of Volcanoes and Glaciers

The Messy Encounter of Volcanoes and Glaciers

Spread the News:ShareLahars, or mudflows from the eruptions of glacier-covered volcanoes, are a threat that the communities of Skagit Valley in northwest Washington live with. These destructive mudflows can be triggered during volcanic eruptions when hot water and debris rush downslope from the volcano and mix with glacial water. A recent study from the Journal of Applied Volcanology by Corwin et al., identifies ways to improve hazard management and community preparedness in Washington’s Skagit Valley, home to Mount Baker, the second most glaciated volcano in the Cascade Range, and Glacier Peak, the second most explosive. The highly populated communities within Skagit Valley remain especially at risk for dangerous mudflows since both Mount Baker and Glacier Peak are considered active lahar hazard zones. All five of Washington’s Cascade Range volcanoes are active. These volcanoes are especially dangerous because in addition to flowing molten lava and spewed ash that can destroy everything downhill, volcanoes with snow and ice at their peaks can create additional perils. Heat from the eruption can melt the snow or ice that has accumulated, create mud, and pour down narrow mountain valleys. This mixture of water and rock fragments that flows downslope of a volcano into a river valley has dangerous repercussions for communities like those in the Skagit Valley. While lahars can be visually stunning when the volcanic material interacts with glaciers —  see the remarkable images in GlacierHub’s recent article on these events in the Kamchatka Peninsula in Far East Russia — lahars can cause extensive damage to the built environment as boulders destroy structures and mud buries entire communities. Moving lahars appear as a roiling slurry of wet concrete and can grow in volume as they incorporate everything in their path —  rocks, soil, vegetation, and even buildings and bridges. Corwin et al. determined that a crucial disaster risk management strategy for lahar events is “whole community” training programs, which emphasize household preparedness and help disaster responders better perform their duties. Since lahars can cause widespread damage to the surrounding environment, it is important for community members to understand how to address the hazard before it occurs. The focus of the research was on the ascription of responsibility on preparedness and the influence of professional participation in hazard management on household preparedness and risk perception. Disaster response professionals know  the best household preparedness measures, yet they sometimes fail to implement these measures in their own households. The study found that this may be a result of professional disaster responders being out in the field during a disaster, instead of in their homes. Even more surprising, response professionals failed to interpret local volcanic hazard maps more accurately than laypeople. There could be several reasons for this that need to be explored in a subsequent study, but as Kimberley Corwin, a geoscientist and the leading author of the study,  explains, it could be because “people in both groups drew on outside information such as what they remembered or learned about the 1980 Mount St. Helens eruption.” When asked by GlacierHub about her familiarity with lahars, Corwin described her closest experience with an active volcano in Chile’s March 2015 Villarrica volcano eruption. Corwin was in Pucón, Chile, for a volcanology course with Boise State University. The group of academics arrived two weeks after the main fire fountain event, which triggered a lahar. There was still active ash venting in the area. “While we were there, the alert levels in the town were elevated and a 5-kilometer exclusion zone was set up around the vent,” Corwin explained. “It offered a great opportunity to observe the reactions of locals, tourists, and officials.” Corwin’s further...

Photo Friday: Andean Herders Cope with Climate Change

Spread the News:ShareAllison Caine was recently living in a community of alpaca herders in the Cusco region of Peru conducting extensive fieldwork as part of her PhD program in anthropology at the University of Michigan. These photographs are an element in her research, which focuses on how alpaca herders evaluate environmental changes and adapt their daily and seasonal practices. In many herding communities in this region,  women are often the primary herders. Glaciers form a key element of Caine’s research. Their rapid retreat in recent decades has altered streamflow and affected the wetlands the herders manage, often negatively. Streamside wetlands are a crucial resource for the herds, particularly in the dry season. The dramatic, visible loss of glaciers has a strong cultural impact as well. The following photos have been provided to GlacierHub courtesy of Allison Caine.               Spread the...

Earthquake in Peru Creates Fear of Glacier Floods

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...

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...
