A warming atmosphere also warms perennially frozen mountains. The stability of frozen rocks decreases with increasing temperature similar to how butter just taken out of a fridge &nbsp;becomes softer and less resistant to &nbsp;the cutting force of the knife. Thawing frozen mountains means softening them, making them less resistant against gravity, leading to breakage of small to large sections, resulting in rock falls, rock avalanches, and landslides. There is growing concern about <a href="https://nepalitimes.com/here-now/for-destruction-ice-is-also-great-and-will-suffice">the impact of global warming</a> on the stability of icy peaks in mountain ranges around the world, which several recent events in the Himalaya well illustrate. Permafrost is a technical short form of ‘permanent frost’ for frozen ground which remains at temperatures below zero degrees throughout the year.&nbsp; Permafrost is below the surface, is not directly visible, and therefore often escapes the attention of scientists and political authorities. Sophisticated methods must be used to explore it, such as drilling, geophysical soundings, or climate-related modelling.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20240907160944_bbe43b730a10b861f318285a1999a1f6f4d245287618ff49ebfc8e51d154f573.jpg" data-media-id="editor_1" data-image-id="20240907160944_bbe43b730a10b861f318285a1999a1f6f4d245287618ff49ebfc8e51d154f573" data-rendition-name="original" width="4108" height="1000" loading="lazy" alt="The not so permanent frost Page 6-7 #1228 NT"> <figcaption>Even small glacial lakes, such as these currently forming near the terminus of the Kangchenjunga glacier in eastern Nepal, can be dangerous.

Polewards to around 60°N and S latitude, mean annual air and ground temperatures are mostly below 0°C. Permafrost is widespread in Alaska, northern Canada and Siberia. The lower limit of negative mean annual temperatures is at &nbsp;2,000-3,000m at mid-latitudes such as the <a href="https://nepalitimes.com/here-now/in-high-places">European Alps</a> or the Southern Alps of New Zealand, to 3,000-4,000m in the Himalaya, and to 5,000m near the equator in the Peruvian Cordilleras. Above these elevations, permafrost affects peaks. In high mountains the permafrost area is often far larger than their glacier-covered regions. In Nepal, the permafrost-affected area is about 2 to 3 times bigger than the glacier area, while in China with the perennially frozen Tibetan Plateau this factor is about 30. Temperatures decrease by 6-7°C for every 1,000m of altitude increase, and the coldest and most deeply frozen rocks are found in the highest parts of the peaks. The frozen zone inside mountains can reach depths of hundreds of metres. It is not just the ice on peaks in the European Alps or the Himalaya that is frozen throughout the year, but so are the rocks.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20240907160944_b75f78e4ee6d146e797f06536491c445891fbeb578f60105f57247a8dc066bbd.jpg" data-media-id="editor_3" data-image-id="20240907160944_b75f78e4ee6d146e797f06536491c445891fbeb578f60105f57247a8dc066bbd" data-rendition-name="original" width="916" height="674" loading="lazy" alt="The not so permanent frost Page 6-7 #1228 NT"> <figcaption>Mt Chamlang (7,319m) with creeping frozen debris (rock glaciers, yellow arrows) and Lakes 464 and 465 (blue arrows) from glacier retreat at its foot.

Temperatures are not constant throughout the year, so a thin surface layer up to a few metres on top of permafrost that thaws in summer and freezes in winter. This seasonal freezing and thawing surface layer on permafrost is called the ‘active layer’. Deep, long-term freezing influences geomorphic processes inside mountains, drastically changing their properties. Growth of ice in cracks and fissures within solid rock tends to expand already existing openings, and even create new ones. The related weakening of bedrock, however, is compensated by strong adhesion and increasing strength induced by the ice fillings and related cold temperatures.

Perhaps most important is the effect of freezing and ice filling of cracks between rocks containing water. Deep frozen rocks are essentially impermeable to water as an often-decisive factor of stability inside mountain slopes. In the abundant debris masses at the foot of high mountains, deep, long-term freezing causes even more spectacular changes. Formation of ice inside and beyond the pores can create a mixture of ice and debris with ice lenses, enabling such ice-rich frozen masses to slowly creep down the slopes of mountains. Landforms resulting from permafrost creep over past millennia look like lava streams and are called ‘rock glaciers’.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20240907160944_dc86dc2e254de22afefcd3f6c2df76af6c0aab87555f702dc853992987dcb3fc.jpg" data-media-id="editor_5" data-image-id="20240907160944_dc86dc2e254de22afefcd3f6c2df76af6c0aab87555f702dc853992987dcb3fc" data-rendition-name="original" width="1072" height="625" loading="lazy" alt="The not so permanent frost Page 6-7 #1228 NT"> </figure>  Thawing out From long-term temperature measurements in deep boreholes, we know that global temperature increase of the atmosphere during the past about 100-150 years has warmed up mountain slopes down to depths below the surface of about 100m. The effect of this deep warming is the reversal of the freezing and cooling effects. It reduces the strength of rocks or debris with ice and makes them ‘softer’ and more permeable to water. Over the past decades, creep rates of frozen debris in rock glaciers have markedly increased, and the frequency of large rock-ice avalanches from high-mountain permafrost has accelerated. In the Peruvian Andes, two major events from mountain permafrost occurred in 2020 and 2023. Both had volumes of 1-1.5 million m3, reached lakes at the foot of the slope, and produced flood waves. The 2020 Salkantay flood caused loss of lives and heavy damage at Santa Teresa, 35km down valley. The flood wave at Rasac was fortunately retained within the lake at lower altitude. On 5 May 2012, a massive rock, ice, and debris avalanche from Annapurna IV <a href="https://nepalitimes.com/here-now/remembering-the-seti-disaster">cascaded into the Seti River gorge</a>, plummeting into a rockfall-dammed lake. The impact triggered an air blast that levelled thousands of hectares of forests, a dust cloud covered the countryside in fine white rock powder, and a hyper-concentrated slurry flood that killed 72 people downstream.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20240907160944_81860cf5896090449c7fd074796f683c164e2bff782a46390cd43eee6202f19b.jpg" data-media-id="editor_7" data-image-id="20240907160944_81860cf5896090449c7fd074796f683c164e2bff782a46390cd43eee6202f19b" data-rendition-name="original" width="780" height="539" loading="lazy" alt="The not so permanent frost Page 6-7 #1228 NT"> <figcaption>Rock failure from Annapurna IV led to a series of cascading events that resulted in the Seti River flood of 2012 that killed 72 people. Map: J  KARGEL / D REGMI(Photo: Shristi Karki)</figcaption> </figure>  On 20 April 2017, a high altitude breakage of solid rock from the east face of Saldim Peak (6,388m) in the <a href="https://nepalitimes.com/here-now/nepal-s-mountains-are-melting">Barun Valley turned into a 1.1 million m3 debris flow</a> of ice and sediment that plummeted 1,200m down to the Langmale Glacial lake below. Although the lake was less than 0.01km2 in size, the combination of lake water with melting ice from the ice-debris flow triggered a massive hyper-concentrated flood that destroyed forests, pastureland, and trekking lodges for several dozen kilometres to the Barun’s confluence with the Arun. In India’s Uttarakhand state bordering Nepal, the Chamoli event of 7 February 2021 was catalysed by the detachment of 20 to 30 million m3 of rocks and ice from a frozen, ice-clad peak. The ensuing avalanche developed into a rapidly flowing mass of rocks, ice and water, killing 204 people and heavily damaging an under-construction hydropower infrastructure 35km downstream.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20240907160944_c7284846f8a571d8d1f5596b7731e7c4c2521f764aaf9e5df23ad9d0ad41d986.jpg" data-media-id="editor_9" data-image-id="20240907160944_c7284846f8a571d8d1f5596b7731e7c4c2521f764aaf9e5df23ad9d0ad41d986" data-rendition-name="original" width="798" height="462" loading="lazy" alt="The not so permanent frost Page 6-7 #1228 NT"> <figcaption>This massive breakage (below) of solid rock from Saldim Peak in 2017 fell on a lake and unleashed a flood downstream on the Barun River.

Each of the above cases show the potential hazard over long distances related to process chains, especially in connection with impacted mobile water bodies in glacial lakes and artificial reservoirs.&nbsp; <h2>12 TIPS: Awareness and Protective Measures</h2> Changes in high altitude permafrost, and the devastating geomorphic events they cause are still poorly understood by Nepal’s scientific community and government. Earthquakes and heavy rainfall are usually reported by the press to be the primary causes of catastrophic events, both of which are impossible to predict. However, climate change and gravity, the two major forces at work on Himalayan permafrost, are constants. As permafrost continues to destabilise at the highest altitudes in the Nepal Himalaya, more and more devastating events can be expected to occur.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20240907160944_dd2d77fb090fb2f5c836411d61bd6e7bb4e2e40ea2abae3d8eee8a686e9457dc.jpg" data-media-id="editor_13" data-image-id="20240907160944_dd2d77fb090fb2f5c836411d61bd6e7bb4e2e40ea2abae3d8eee8a686e9457dc" data-rendition-name="original" width="977" height="733" loading="lazy" alt="The not so permanent frost Page 6-7 #1228 NT"> <figcaption>Gabions installed near Chukung in 2015 protected the village from a similar flood from the Lhotse Glacier in 2014. Photo: ALTON BYERS(Photo: Shristi Karki)</figcaption> </figure>  The question is, what can we do about it? Based on our collective experience in the European Alps, Peruvian Andes, and Nepal Himalaya over the past several decades, we offer the following suggestions: 1. Encourage more permafrost and hazard research. Nepal’s scientists and practitioners need to better understand and acknowledge the role of permafrost change in the growing list of climate change-related impacts in the high mountain environment, and more research of an applied nature is indicated. Interdisciplinary approaches that include and involve local people usually yield the most promising and effective results. 2. Standardise glacial lake risk assessment methods. Currently, scientists use various methods to assess a lake’s potential danger of flooding, with predictably mixed and widely differing results. Imja glacial lake in Khumbu, for example, is considered by some scientists to be extremely dangerous, and by others to have a low to moderate risk. The result is confusion among local people, local governments, and scientists alike. 3. Update and revise the current list of potentially dangerous glacial lakes in Nepal. The inventory should incorporate the changing permafrost factor, including smaller lakes less than 0.01km2. Even very small glacial lakes, such as those above Thame and the Langmale glacial lake in the Barun, can be as destructive as large lakes under the right conditions and cascading processes. 4. Develop new feasibility study protocols for large hydropower projects. These guidelines must incorporate the changing permafrost factor as well as the heightened threat of glacier floods. The potentially disastrous impacts of climate change upon major hydropower projects in Nepal have been predicted by scientists for decades, and yet the construction (and destruction) of major, multi-million-dollar installations continues. Hundreds of lives, and millions of dollars of infrastructure, stand to be saved through the use of more detailed, comprehensive evaluations of permafrost and glacier-related risks prior to project implementation. 5. Develop zoning policies. These should discourage the location of farms and infrastructure (homes, tourist lodges) within known and active floodplains. Some scientists believe that most of the deaths from the 2012 Seti flood could have been prevented had settlements not been located directly in the floodplain. 6. Simple is beautiful. Rock-filled wire cages (gabions) can be engineered to effectively divert floods and should continue to be promoted in high mountain regions. In the village of Chukung located directly in the floodplain of the Lhotse Glacier in the Sagarmatha National Park, for instance, the installation of gabions after a glacier flood in 2015 protected the village the following year when a second similar flood from the same glacier occurred.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20240907160944_ce975f82275c7936c7948fbf7fd7231b61adecc01d5510760144a8f3d0467859.jpg" data-media-id="editor_14" data-image-id="20240907160944_ce975f82275c7936c7948fbf7fd7231b61adecc01d5510760144a8f3d0467859" data-rendition-name="original" width="1005" height="695" loading="lazy" alt="The not so permanent frost Page 6-7 #1228 NT"> </figure>  7. Build higher bridges. This can effectively address the growing frequency and magnitudes of glacier floods in the high mountains, eliminating the need for continuous rebuilding. 8. Increase awareness. Nepal’s mountains will continue to destabilise and become even more dangerous in future. Exercising extra caution while crossing a landslide, an active torrent, or a debris-covered glacier is a fact of life in today’s high Himalayan regions. Likewise, constructing a lodge, school, or community building beneath a small and seemingly harmless glacial lake should be discouraged. 9. Promote simple and effective early warning systems. In spite of their much-touted role in disaster mitigation, early warning systems installed to date at potentially dangerous glacial lakes in Nepal have proven to be expensive disappointments. They are typically installed by a remote and distant government agency, little training in their use by local villagers is offered, and local people say they have no idea what the warning sirens sound like nor what they should do if one goes off. Thus far the most effective and proven EWS tool has been the cell phone. Hundreds of lives were saved during the Seti River flood of 2012 when upstream witnesses phoned warnings to their downstream family and friends. 10. Improve mechanisms that allow scientists to communicate. The results of their permafrost and glacier hazard research should directly, quickly, and effectively be communicated to decision-makers. This has proven to be easy to recommend but difficult to implement in most of the world but is nevertheless in need of our constant efforts to achieve. 11. Encouraging transboundary permafrost research. Increased cooperation between scientists and researchers in Nepal, China, and India is needed to help identify potentially vulnerable crossborder rockfall, avalanche, and catastrophic flooding risk. 12. Develop and implement adaptation planning. Continue planning and training programs targeted at permafrost-related floods and other highland-lowland hazards. Local Adaptation Plans for Action (LAPA) have proven to be an effective tool for increasing local awareness of climate impacts as well as planning for mitigation measures.

The not-so-permanent frost

Earlier this month, Nepal received Rs1.6 billion from the World Bank as part of its <a href="https://nepalitimes.com/news/will-nepal-ever-be-paid-for-saving-trees">Forest Carbon Partnership Facility (FCPF)</a>, rewarding the country for increasing its carbon sink capacity. Nepal is the first in South Asia to benefit from this facility, and it is specifically to recompense the country for increasing forest cover in 13 Tarai districts between 2018-2024. “We are also trying to get another Rs13 billion from the facility while also preparing for free market-based carbon trading in the international market,” says Nabaraj Pudasaini of the REDD (Reducing Emissions from Deforestation and Forest Degradation in Developing Countries) Implementation Centre. Big emitters of greenhouse gases are under pressure to reduce their carbon emissions, and many have signed agreements to do so by investing in decarbonisation projects in developing countries. Countries that emit more than a specified amount of carbon would be able to buy emission rights from countries that emit less. Nepal is internationally known for its community forestry program which has been largely credited for <a href="https://nepalitimes.com/banner/tree-mendous">increasing tree cover to over 45%</a> in less than three decades. But this achievement had not been adequately recognised or rewarded internationally before. Forests, especially in the tropics, absorb and store large amounts of carbon while releasing oxygen in a process known as photosynthesis. <a href="https://www.fao.org/forest-resources-assessment/en/">Preventing deforestation</a> and increasing canopy cover is considered a much more achievable goal than reducing emission in the scale necessary to limit global average temperature to 1.5°C above pre-industrial levels. COP11 in Montreal in 2005 first proposed reducing carbon emissions by improving forest quality by halting degradation. By 2015, a new mechanism of financial assistance was created to help less developed countries with sustainable management of forests <a href="https://www.un-redd.org/">(called REDD+)</a>. Under this new mechanism, countries receive aid based on their efforts to prevent forest degradation and increase carbon sink, and in 2021 the World Bank was entrusted with implementing it. Nepal’s FCPF receipt this month was calculated on the basis of 2.4 million tons of carbon stored at a rate of $5 per ton. In the second phase, Nepal will receive more than Rs4 billion within the next year for storing an additional 7 million tons of carbon. Eighty per cent of this amount obtained from carbon trading needs to be spent on local beneficiaries and indigenous communities.&nbsp; But carbon trading is not easy, Nepal needs to prove that protected forests will not be destroyed in future.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20241121091132_c8a381c9a95aa86fec558951650d97bb87914741f01766982ba2b086af001f16.jpg" data-media-id="editor_4" data-image-id="20241121091132_c8a381c9a95aa86fec558951650d97bb87914741f01766982ba2b086af001f16" data-rendition-name="original" width="1500" height="999" loading="lazy" alt="Greenbacks for greenery NT "> <figcaption>Photo: KUNDA DIXIT</figcaption> </figure>  Explains carbon trading expert Yugan Manandhar. “Forests should be handed over to the community and shown that they are managed sustainably. Proving this will be particularly challenging; forest encroachment and degradation is rife in the Tarai.” <a href="https://nepalitimes.com/multimedia/nepal-is-going-up-in-smoke">Deliberate forest fires</a> have also added to the challenge because they increase carbon emissions and reduce the sink capacity of forests. The basis for the amount that Nepal received was set five years ago by calculating the carbon reserves of forests in the 13 Tarai districts. In the meantime, sustainable forest management, tree plantation, forest destruction and erosion control were prioritised to increase carbon reserves in those forests. Nepal is signing another carbon trading agreement during the ongoing Baku climate conference. The <a href="https://www.leafcoalition.org/">Lowering Emissions by Accelerating Forest finance (LEAF Coalition) </a>proposes to sell the carbon stored in the forests of Bagmati, Gandaki and Lumbini provinces. For this, Nepal signed the letter of intent three years ago at COP26 in Glasgow. The target is to store 70 million tons of carbon in 32 million hectares of forest in the three provinces per which Nepal will receive Rs13 billion in four years at $10 per ton with provisions to increase the rate if various conditions are met. However, the agreement in itself doesn’t guarantee the amount. According to the targets set by Nepal, forest degradation should be stopped and carbon reserves increased by protecting tree cover. Preparations are also underway for clean air carbon trade because it has offset fossil fuel use by introducing 30,000 electric vehicles. Nepal has been selected for the first round to receive $40 million within one and a half years through the Clean Air System of the World Bank. Given that most of Nepal’s energy mix is from biomass, replacing them with electric stoves can significantly improve health by reducing indoor pollution as well as strengthen the country’s capacity for carbon trade. “Nepal's goal now is to sell carbon in the free market where carbon credits are bought and sold based on supply and demand in an open and transparent manner,” adds Pudasaini of the REDD Implementation Centre. “Nepal can now set its own price and bargain with interested buyer countries and organisations.” Lately, India has been discussing setting up a carbon market. Nepal has exported Rs12.72 billion worth of electricity to India so far this fiscal year, which can be traded under Nepal’s carbon market. “Carbon trading can create significant economic benefits for Nepal, which will help reinvest in development and environmental protection projects,” says Manandhar. “But we must prioritise sustainable management of forests, cutting older trees and allowing regrowth as well as promoting electric stoves and electric vehicles.”

Greenbacks for greenery

Khukri Rum is <a href="http://archive.nepalitimes.com/news.php?id=3719#.WurBk6SFPIU">one of Nepal’s most iconic brands</a>, and is now launching a new Cask Series premium product to sell in Nepal and abroad. The Cask Series Smoked Finish Khukri Rum is a limited edition with only about 7,000 bottles, most of it for export and rest to be sold to rum connoisseurs in Nepal itself. Each bottle is numbered and will mention the cask from which it is derived. “We are working on taking a classic Nepali rum to a new luxury premium brand category, the Cask Series will only be produced this year with new product ranges in future,” explains Subash Lamichhane, managing director of Nepal Distilleries that first started making Khukri rum in 1959 in Balaju and has never stopped. Fermented from molasses in Bara district in the Tarai after the annual sugarcane harvest, the rum is matured for at least eight months during distillation. The distillery bottles the classic Khukri XXX, Coronation Khukri XXX, Khukri White Rum and Khukri Spiced Rum.&nbsp; The distillery is now adding this limited edition of its ‘Cask Series’. While the original rum is stored in huge wooden vats, the rum used for this more exclusive line is in smaller casks made either from oak or sal, with charred insides to give the rum a smoky flavour. The Cask Series rum is indeed smokier than the classic, while the spiced rum tastes toasty and mostly of cardamom. The company has a tasting suite with a master blender and tasters who have to approve the palate test.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20241122131124_10b8ddca93b37b0348bf964b4f09e7fac6ef4e754cca6231368850539cd558e2.jpg" data-media-id="editor_1" data-image-id="20241122131124_10b8ddca93b37b0348bf964b4f09e7fac6ef4e754cca6231368850539cd558e2" data-rendition-name="original" width="1498" height="1000" loading="lazy" alt="Khukri Rum"> </figure>  The packaging for the Cask Series is as special as the process. A sturdy patterned box that opens up to a black glass bottle with gold lettering, and an indication of which cask the rum is from. These are then shipped to premium customers around the world One of the reasons this is the more expensive premium line is because the casks are smaller than the vats and the blenders reject more than half of the rum in the casks when the aging period is complete. The trick for the blender is also to decide when to take the run out of the cask.&nbsp; Says Lamichhane: “If we have 25 casks, we expect to throw away about fifteen.”Over the decades, Nepal Distilleries have created and maintained a brand that feels quintessentially Nepali, and has served as Nepal’s ‘ambassador’ with exports to Germany, Korea, Belgium, Finland, the Czech Republic, besides the existing markets among Nepalis in the US, UK, Hong Kong and Australia. &nbsp;Its unique <a href="https://nepalitimes.com/here-now/khukri-rum-sharpens-its-act">khukri shaped bottle</a> first introduced for King Birendra’s coronation in 1975 has been a collector’s item. The bottle and rum have been a staple for Nepalis and visitors to take as gifts when they leave the country, and is used as decoration on bar tables around the world. Now, nearly 40 years later, even that bottle will soon be getting a makeover with a sharper design and sleeker handle. “Our bottle design has always been instantly recognisable, and it is,” says Lamichhane. The Himalayan restaurant at The Hague, for example, has a Khukri Coronation bottle adorning its bar (page 6-7). In Washington DC Himalayan Heritage Restaurant &amp; Bar offers ‘Nepalese Khukri Rum’ mojito in its drinks menu with fresh mint, soda water, lime juice and sugar syrup, for $12.&nbsp;  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20241122131124_b9474db3fc83c85845348dddc30c49652ee1f17229531867fa241de50849cedc.jpg" data-media-id="editor_3" data-image-id="20241122131124_b9474db3fc83c85845348dddc30c49652ee1f17229531867fa241de50849cedc" data-rendition-name="original" width="1500" height="1000" loading="lazy" alt="Khukri Rum NT"> <figcaption>Christopher Armes, master blender of the Cask Series.</figcaption> </figure>  A distinct element of the award-winning <a href="https://nepalitimes.com/business/khukri-rum-gets-award">classic Khukri rum</a> is its burgundy colour from caramel sourced from cooking sugar and blended with the raw rum. The spirits are then stored in a warehouse with floor-to-ceiling vats. The vats are not just for storage, the wood in the vats imparts flavour into the rum, and removes a lot of the harshness. &nbsp; On a visit this week, the bottling room was just about to begin for the day and the production line was churning out different shapes and sizes of Khukri Rum bottles. Most of the process is automated, including screwing bottle caps, sticking labels, placing the government seal, and packaging. The only manual intervention is the quality control where bottles are held against the light to check for sediment and colour. A mural on the wall of the distillery in Balaju depicts the rum-making process. A lady slings sugarcane on her shoulder, the molasses is churned in a pot, water is channelled into the distillation process, cinnamon, cloves and cardamom are added to a container, and finally there is a bottle of the classic Khukri Rum against a Kathmandu backdrop.

Nepal now generates a surplus of electricity and it is all from renewable hydropower. Nearly half the country is under forest cover. Despite meeting these decarbonisation goals, Nepal’s hydropower plants are threatened by increased risk due to climate impact.&nbsp; Till <a href="https://nepalitimes.com/editorial/when-it-rains-it-pours-ksqprbu3">28 September</a>, Nepal was <a href="https://nepalitimes.com/news/india-nepal-sign-power-exchange-deal">exporting just over 1,000MW</a> of electricity to power-hungry India, when flash floods and landslides unleashed by historically heavy rains damaged over 30 hydropower plants across the country, temporarily <a href="https://nepalitimes.com/news/power-to-the-people">slashing nearly half the power generation.</a> The 456MW Upper Tamakosi in Dolakha was the hardest hit and it will take six months and Rs2 billion to repair. This has significantly reduced exports as well as domestic generation. Two months later, Nepal has still not been unable to fully keep its export commitment, and is actually paying Rs100 million in fines to India. Thirty-seven existing and under construction projects under the Independent Power Producers' Association Nepal (IPPAN) suffered Rs2.5 billion in damage. One of them is the 22MW Bagmati project in Makwanpur which was almost completely buried in flood debris. Even before <a href="https://nepalitimes.com/news/60-dead-64-missing-in-nepal-floods">record-breaking rain in September</a>, 15 other hydropower projects had been damaged by floods. Last year, floods caused by heavy localised rain damaged 28 hydropower plants. World governments met in Baku for COP29 to discuss the Loss &amp; Damage Fund and the Adaptation Fund, but for countries like Nepal the commas and brackets are meaningless until they are turned into $ and €. And likelihood of adequate compensation for climate-related damage is a long way off, if ever. Nepal’s national strategy is to use its vast hydropower resource as clean energy to spur economic growth, job creation, and boost export revenue. But the plants are located in narrow Himalayan valleys prone to landslides and floods even at the best of times. Now, those <a href="https://nepalitimes.com/opinion/comment/changing-climate-for-investment-in-nepal">risks have been heightened by weather extremes</a> due to climate breakdown. At present, Nepal generates over 3,300MW of clean hydropower, and the target is to reach 12,700MW in the next five years. Projects equivalent to 6,000MW are under construction or ready to start. The Ministry of Energy, Water Resources and Irrigation has an Energy Development Roadmap and Action Plan with the target of producing 28,500MW by 2035 by when more than half of it will be exported.&nbsp; “The climate crisis will further change the rainfall patterns making hydropower generation a big question mark in the future,” Manjeet Dhakal in Baku, who is also the Nepali adviser to the LDC Chair at the United Nations Framework Convention on Climate Change (UNFCCC). “We are building hydropower projects on rivers without evaluating risk. This whole process needs to be reviewed and reconsidered.” The report of the National Adaptation Plan published by the Ministry of Forest and Environment last year mentions that hydropower production, transmission and distribution will be at risk from flash floods, debris flows, glacial lake outbursts and rising temperatures.&nbsp; This risk is not confined to Nepal. Average global temperatures have increased by 1.3°C compared to the pre-industrial era. Worse, the Himalayan mountains are warming faster than the global average by 0.7°C because of elevation-dependent warming. A study conducted by our own Department of Hydrology and Meteorology in 2017 showed that the average temperature in Nepal has increased in the last four decades. Scientists say this is leading to extreme weather unleashing floods and landslides on slopes already destabilized by seismicity.&nbsp;  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20241124071128_d22901a360e8958f606d80ffa21defba05a671f65afec65539dc21a6885d8345.jpg" data-media-id="editor_5" data-image-id="20241124071128_d22901a360e8958f606d80ffa21defba05a671f65afec65539dc21a6885d8345" data-rendition-name="original" width="1333" height="1000" loading="lazy" alt="Right climate for Nepal’s energy transition NT"> <figcaption>BIBLICAL RAIN: Photo taken during catastrophic rain on 27-28 September at the Upper Tamakosi project site that destroyed the control room, killing four staff and burying the sedimentation tanks. Photo: RSS</figcaption> </figure>  Increased atmospheric temperatures has made the monsoon rains more erratic. It does not rain when it is supposed to, and it comes down in torrents when it is not supposed to. The September floods happened two weeks after the monsoon was supposed to retreat from central Nepal. Kathmandu Valley received half its annual precipitation in just over a day. &nbsp; Winter precipitation has also failed, especially in the high mountains and trans-Himalayan valleys. Thirteen of the past 19 years experienced winter drought. This impacts on dry season flows of the rivers, reducing hydropower generation. Nepal’s power capacity normally goes down by one-fourth during winter, but the gap is widening. The Kabeli corridor could only generate 20MW November-March even though plants there have an installed capacity of 200MW. Similarly, Upper Tamakosi only produced 65MW at most against its 456MW capacity last winter. The Nepal Electricity Authority (NEA) pays producers double the price for winter electricity, Rs8.40 per unit. Even though winter operation is highly profitable the rivers run low and NEA has to import from India to meet the winter demand. “This is not just a weather problem but a serious challenge also for the country's energy future, good climate-friendly design should be combined with policy and effective implementation,” says Subarna Das Shrestha, a hydropower investor and CEO of Sanima Mai Hydropower. “Insurance premiums have gone up as well, and settlement for damage is not timely.” <a href="https://nepalitimes.com/opinion/climate-risk-to-hydropower-investment">Hydropower investment</a> at one time was regarded as having a high rate of return. Now, some investors have become <a href="https://nepalitimes.com/banner/climate-smarter-himalayan-infrastructure">wary of the risks involved</a>. Says IPPAN’s Uttam Blon Lama: “Hydropower projects expected to give stable returns are now looking risky. Not only is climate adaptation design and planning expensive, but future repair and maintenance costs will also skyrocket.” Nepal has only one storage type dam <a href="https://nepalitimes.com/multimedia/rivers-be-dammed">in Kulekhani</a> and another one is being built in <a href="https://nepalitimes.com/multimedia/missing-pieces-of-the-hydropower-jigsaw">Tanahu</a>, but they are also at risk. In September, the sluice gates of Kulekhani Dam had to be opened causing loss of life and destruction downstream. Nepal has to learn lessons from the deadly collapse of the $1 billion <a href="https://nepalitimes.com/news/sikkim-flood-is-warning-to-nepal">Chungthang Dam in Sikkim</a> in October 2023 cause by a glacial lake burst. Glacial Lake Outburst Floods (GLOFs) in Nepal pose potentially catastrophic risk to infrastructure. The <a href="https://nepalitimes.com/here-now/lives-on-the-line-in-the-himalaya">Thame flood in August</a> was a relatively minor debris flow that damaged half of this village in the Everest region when <a href="https://nepalitimes.com/news/climate-breakdown-linked-to-thame-flood">two glacial lakes at 4,760m burst</a>. Luckily there was no loss of life. Of the <a href="https://nepalitimes.com/here-now/lives-on-the-line-in-the-himalaya">47 high-risk glacial lakes</a> in the eastern Nepal Himalaya, 21 are in Nepal and the rest are in rivers in China that are tributaries of the Arun and Bhote Kosi where Nepal has major hydropower plants under construction, or planned.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20241123021128_b596cd8520c57a6c5476031e7a3ea6510f26b464c4d5351d2bc10f6f7d6b70d8.jpg" data-media-id="editor_14" data-image-id="20241123021128_b596cd8520c57a6c5476031e7a3ea6510f26b464c4d5351d2bc10f6f7d6b70d8" data-rendition-name="original" width="871" height="648" loading="lazy" alt="Page 10-11 map #1236 NT"> </figure>  Global temperature rise is accelerating the melting of Himalayan snow and ice, increasing the <a href="https://nepalitimes.com/here-now/living-below-nepal-s-melting-mountains">number and size of glacial lakes</a> so that we do not even have names for them. Imja Tso did not even exist in the old trekking maps until 25 years ago, but is now a 2km long lake. “Natural moraine dams in the mountains are weak, and the projects downstream can face major destruction if they burst, and the risk will only increase in future,” warns climatologist Arun Bhakta Shrestha at the <a href="https://www.icimod.org/">International Centre for Integrated Mountain Development (ICIMOD)</a>. <a href="https://nepalitimes.com/here-now/terrifying-assessment-of-a-himalayan-melting">An ICIMOD assessment in 2019</a> projected that if present heating trends continue, as they probably will, the Himalaya will lose two-thirds of our glaciers by the end of this century. “Generally speaking, hydropower developers hand over the project to the government after 30 years but by that time given the climate risks, they may not be an asset anymore,” says Manjeet Dhakal. Indeed, the cascade of expensive projects India is building on the Arun River are supposed to be handed back to Nepal in 25 years, but there is a big ‘if’ about whether they will survive that long. &nbsp;&nbsp; Planning of hydropower projects is still based on historical hydrological data, and does not take into account future temperature rise and its consequences. Investors, on the other hand, say that planning hydropower projects with climate components would make them even more expensive.&nbsp; “It’s not that we aren’t preparing for climate risk, we design keeping in mind the once-in-100-year flood,” says Blon of IPPAN. “But if we start designing based on once in 1,000 years flood, the cost would be so high that we won’t be able to build them at all.” Nonetheless, Subarna Das Shrestha of Sanima Mai Hydropower says that there is no option but to go for climate smart infrastructure despite the higher cost. Sanima Mai's powerhouse, for example, is completely underground. The strategy could also be to spread the risk by building less expensive plants located on rivers all over the country. Nepal is also diversifying away from its sole reliance on hydroelectricity, which at present supplies 92% of the power in the grid. Most of the rest comes from solar plants, where the total potential has not even been scratched. &nbsp; This article is brought to you by <a href="https://nepalitimes.com/" target="_blank">Nepali Times</a>, in collaboration with <a href="https://inpsjapan.com/en/" target="_blank">INPS Japan</a> and <a href="https://sgi-peace.org/" target="_blank">Soka Gakkai International</a>, in consultative status with UN ECOSOC.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20240630110640_30c3782f9c09219bf1c249b51483a3cfb7a53a06d117d2aebd23ca7080d12758.jpg" data-media-id="editor_21" data-image-id="20240630110640_30c3782f9c09219bf1c249b51483a3cfb7a53a06d117d2aebd23ca7080d12758" data-rendition-name="original" width="680" height="103" loading="lazy" alt="SDG logo"> </figure>  &nbsp;
