The<a href="https://nepalitimes.com/news/rasuwa-flood-likely-a-glof"> flood on the Bhote Kosi</a> on Tuesday morning was a timely reminder about the risks Himalayan communities face from melting permafrost and glaciers, as well as the need for transboundary early warning. In the spring of 2024, I visited the Kanchenjunga Conservation Area (KCA) again. While in the village of Kampuchen (4,145) I visited Nupu Sherpa, friend and owner of the Kampuchen White House Lodge, to share <a href="https://tc.copernicus.org/articles/18/711/2024/">a new paper we had just published</a> about a massive ice-debris avalanche that had occurred in 2022 in the upper Nupchu valley. Although Nupu was interested in the results and implications of the avalanche, he was even more concerned about the recent and rapid development of several large, pro-glacial lakes upon the terminus of the Kanchenjunga glacier, an hour walk north of Kampuchen and across the seasonal yak pasture of Ramdang Kharka (4,375m).&nbsp; Like many high altitude, low gradient glaciers in the Himalaya, those in the Kanchenjunga region had shrunk to mere shadows of their former selves during the previous 125 years, leaving behind debris-covered remnant ice and small meltwater ponds.&nbsp; Nupu’s fear was that the lakes might soon coalesce to form a large and potentially dangerous glacial lake. Given a large enough trigger, such as a massive landslide or avalanche, a glacial lake outburst flood (GLOF) could result that could damage Kampuchen, Ghunsa, Phale, the Kangchenjunga Base Camp trail, and even beyond to the lower Tamor into India.&nbsp;  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/2025071204070_31e28d1fd0f5a976ad96fc5597cc386586d7de5b7d9714835d5b479104209fed.jpg" data-media-id="editor_2" data-image-id="2025071204070_31e28d1fd0f5a976ad96fc5597cc386586d7de5b7d9714835d5b479104209fed" data-rendition-name="original" width="1500" height="1635" loading="lazy" alt="Meltpools in the Himalaya"> <figcaption>The Kanchenjunga Conservation Area (KCA), eastern Nepal.</figcaption> </figure>  Since I was on my way to the village of Lhonak (4,792m) I stopped to take a look at the new lakes. Sure enough, from a lookout point on the lateral moraine of the Kanchenjunga Glacier I could see as many as ten newly formed and growing meltwater ponds upon the terminal moraine region of the glacier.&nbsp; The prospect was reminiscent of early satellite images taken of Imja Glacier in 1962 by the French, showing a number of meltwater ponds that within 15 years had grown and merged into a glacial lake half a square kilometer in size and containing 45 million cubic meters of water. Ten years after that Imja had grown to more than a square kilometer in size, was at least 120 m deep, and contained an estimated, and growing, 90 million cubic meters of water. Would the same scenario play out for the lower Kanchenjunga Glacier? To try and understand the situation better, glaciologist Sonam Wangchuk of ICIMOD put together a time series composite of lake development over time, from 2016 to 2024, where it was clear that the majority of the new lakes had only formed since 2019.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/2025071204078_c65a5ec574a251489c502f3efdf842033e0d238fd57947f7eee2c5793aac2a29.jpg" data-media-id="editor_3" data-image-id="2025071204078_c65a5ec574a251489c502f3efdf842033e0d238fd57947f7eee2c5793aac2a29" data-rendition-name="original" width="602" height="686" loading="lazy" alt="Meltpools in the Himalaya"> <figcaption>Time-lapse satellite images of glacial lake development from 2016 to present. Animation of the process can be seen at https://www.mdpi.com/article/10.3390/w17101457/s1.</figcaption> </figure>  Sonam Rinzin of Newcastle University estimated the potential depth and volume of the future glacier lake using standard procedures based upon the surface slope of the Kanchenjunga Glacier combined with volume-area curves for similar glacial lakes, estimating that the future lake would have a volume of approximately 33 million cubic meters of water and depth of more than 116 m. Other modeling methods enabled the mapping of probable ice, debris, and/or rock avalanches into the lake that could trigger a GLOF.&nbsp; A third model was then used to simulate four different avalanche scenarios that could trigger a GLOF: from small (debris avalanche of 3 million cubic meters) to the worst case (15 million cubic meters) of fast-moving debris. Even under the small magnitude scenario, avalanche-triggered outburst floods would travel distances of almost 120km downstream, and under the worst-case scenario the floods would reach the Indo-Gangetic Plain and cross the border into India, damaging or destroying up to 90 buildings and 44 bridges. The prospective triggers of a future GLOF, however, are not limited to a nearby rock avalanche. A <a href="https://tc.copernicus.org/articles/11/443/2017/tc-11-443-2017.html">sudden release of water</a> from water-filled caves further up the glacier could trigger a surge wave capable of breaching the terminal moraine complex holding in the lake water.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20250712040716_20ed87368a9ac416b5d0232cf8e02211195ca6bc9fff960a1f7e43a95bdfbbf9.jpg" data-media-id="editor_5" data-image-id="20250712040716_20ed87368a9ac416b5d0232cf8e02211195ca6bc9fff960a1f7e43a95bdfbbf9" data-rendition-name="original" width="1500" height="1621" loading="lazy" alt="Meltpools"> <figcaption>Theoretical Kangchenjunga glacial lake of the future (blue) contained by a front moraine (purple) with a flood possibly triggered by a massive rock avalanche (red).</figcaption> </figure>  <a href="https://nepalitimes.com/multimedia/the-not-so-permanent-frost">Weakening permafrost</a> at the highest altitudes could result in massive ice-debris avalanches, such as those believed to have triggered recent and catastrophic floods in the <a href="https://nepalitimes.com/here-now/remembering-the-seti-disaster">Seti River</a>, <a href="https://nepalitimes.com/here-now/nepal-s-mountains-are-melting">Barun Khola</a>, <a href="https://nepalitimes.com/news/non-climate-cause-of-nanda-devi-flood">Chamoli</a>, <a href="https://nepalitimes.com/news/sikkim-flood-is-warning-to-nepal">South Lhonak lake</a>, and Tuesday’s Bhote Kosi flood in <a href="https://nepalitimes.com/news/rasuwa-flood-likely-a-glof">Rasuwa</a>.

The remaining debris-covered glacier is now several hundred meters below the crests of the lateral moraines. Photo: E. BYERS</figcaption> </figure>  But will a large and potentially dangerous glacial actually form at the Kanchenjunga glacier? There’s really no way to tell at this point, although the rapid development of lakes since 2016 is a strong indicator that a large lake is in the process of forming. And rather than wait and see, our current uncertainty does not diminish the need for a more proactive approach to the development of a large glacial lake at some point in the near future. For example, the lower Kanchenjunga Glacier clearly needs to be regularly monitored over the coming years to keep track of glacial lake growth and potential hazards. This could be done by the Department of Hydrology and Meteorology (DHM), ICIMOD, or Kathmandu University with results regularly shared with local people and local governments.&nbsp; In fact, such a service could be developed into a program that is offered to other communities throughout highland Nepal who experience similar situations of glacial lake development, growth, and prospective danger, especially since most communities presently feel that they have no one to turn to for similar information. Inexpensive, locally appropriate, user-friendly early warning systems (EWS) need to be developed for the Kanchenjunga region now, instead of waiting for a tragedy to happen. While the different options and costs are being assessed, the installation of new cell towers in the upper Ghunsa Khola would assure that local residents have access to one of the most effective and proven EWS systems available: cell phones, combined with a lake level monitoring device that broadcasts data and connects to cell phone alarm systems.&nbsp; For example, hundreds of lives were saved when upstream witnesses called their family and friends downstream to warn them of the <a href="https://archive.nepalitimes.com/article/nation/Anatom-of-a-Himalayan-tsunami,1330">Seti River flood</a> near Pokhara in 2014. New zoning policies that prohibit the construction of lodges and other infrastructure in high-risk floodplain regions need to be developed now. Where the infrastructure already exists, villages should be encouraged to install gabion rock-filled wire cages along susceptible river channel or river interfaces to divert the flow of water during a flood event, a method used successfully in both highland and riverine Nepal. Local and national hazard training and response programs need to be developed now. Several examples of excellent programs developed by different organisations in the upper Khumbu region exist that provide excellent models, such as those tested by the US Agency for International Development <a href="https://www.hillarymedal.com/Khumbu-Nepal-Local-Adaptation-Plan-of-Action-%20report.pdf">(USAID) and ICIMOD</a> between 2011 and 2015. Glacial lake reduction&nbsp; Nepal was recently awarded a $36.1 million award by the Green Climate Fund (GCF) to directly confront many of hazards from glacial lake outburst floods jointly implemented by the United Nations Development Programme (UNDP) and the DHM building on past successes at Tso Rolpa and Imja Lakes. There are some lessons learned over the past decades of field work based in Nepal and Peru: 1. The DHM wants to use the project to reduce GLOF risks in Kosi and Gandaki basins and glacial lake reduction programs are planned for Thulagi, Lower Barun, Lumding Tsho, and Hongu 2 glacial lakes.&nbsp; However, the planned lowering depth for Tso Rolpa in 2000 was 20m, with the project ending once 3m lowering was achieved due to lack of funds. Imja lake, which scientists also determined needed to be lowered by at least 20m, was in fact lowered by 3m in 2016 ‘because that’s what they did at Tso Rolpa’.&nbsp; If glacial lake reduction programs are to be implemented under the GCF program they should be based upon good science, and lowered to an effective depth, otherwise the activity will be a waste of funds. <a href="https://sinia.minam.gob.pe/sites/default/files/siar-%20ancash/archivos/public/docs/usaid_glacial_lake_handbookrfs_0-ilovepdf-%20compressed_0.pdf">Peru offers experience</a> for glacial lake lowering. 2. Although large glacial lakes (more than 1sq km) will always command the most media and even scientific attention, it has become abundantly clear in recent years that even small glacial lakes can be just as deadly, given the correct sequence of cascading events, rainfall, snowmelt, and/or other triggers.&nbsp; The 2017 <a href="https://link.springer.com/article/10.1007/s10346-018-1079-9">Barun flood</a> and September 2024 <a href="https://www.stimson.org/event/the-%20thame-glof-disaster-climate-related-disaster-risk-management-in-the-high-himalayas/">Thame flood</a> are two excellent examples. Methods for assessing the flood risk of glacial lakes will need to be revised accordingly to include many of these smaller glacial lakes as well, in addition to the 21 large lakes already considered to be dangerous. 3. Existing and expensive EWS might benefit by some consideration of cheaper, more local, and possibly more effective alternatives. In 2015, for example, <a href="https://digitalcommons.macalester.edu/himalaya/vol37/iss2/7/">villagers</a> living below Tso Rolpa complained that they had no idea how the recently installed EWS worked, what it sounded like, and what to do in the event that it went off. With improved cell service and real-time lake level monitoring apps, local people could check on the lake whenever they wished, as opposed to waiting for some kind of communication from Kathmandu. 4. The GCF grant has the opportunity to become the ‘go to’ place for communities throughout highland Nepal to report any of their concerns related to glacial lakes and/or other observed cryospheric processes. This service could facilitate local people’s ability to adapt to, mitigate, or prevent a range of climate change-related hazards largely unknown to previous generations.

Meltpools in the Himalaya

The greening of the Khumbu

Many of us former Nepal Peace Corps volunteers (PCVs) would agree that our time in Nepal changed in significant but very different ways our perspectives on life if not the future paths we chose to follow. Of no one was this truer than Dorothy Mierow. Dorothy was born in 1920, in Colorado Springs. Her father Charles C Mierow was a classics scholar and Latin professor, who served for ten years as president of Colorado College.&nbsp; Dorothy developed an interest in animals as a child, graduated with a BA degree in natural history from Carlton College in 1942, a Master’s in biology from the University of Pittsburgh, and another Master’s in geography from the University of Minnesota.&nbsp; As a young woman, Dorothy traveled with her father throughout Europe, including a visit to ancient Greek ruins, and took a Magellan Tour by cruise ship around the world in 1958.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/2025071901074_0bad133ab22aada319e74bbad95d563e191371db291c08f373839fbd15440262.jpg" data-media-id="editor_0" data-image-id="2025071901074_0bad133ab22aada319e74bbad95d563e191371db291c08f373839fbd15440262" data-rendition-name="original" width="903" height="1178" loading="lazy" alt="How the Peace Corps changed a volunteer's life"> <figcaption>HOME AWAY FROM HOME: Dorothy Mierow as a college student in her native Colorado.</figcaption> </figure>  She was a college teacher during much of the 1940s, also teaching at a girls’ school in Hawaii. Then back to her native Colorado in 1953, where she became a curator and later director of the Colorado College Natural History Museum. She taught geography classes, and in her free time, Dorothy climbed 22 of Colorado’s 14,000-foot peaks. Traveling in India in 1960, Dorothy decided to spend two weeks in Nepal. In late 1961, she filled out an application to join the Peace Corps and specified that she wanted to go to Nepal, ‘because I admired the people so much when my father and I were there on our trip’.&nbsp; Dorothy reached Kathmandu in September 1962 as the first group of American Peace Corps volunteers in Nepal. She stood out from the others: one of the few women in that group, surely the oldest at age 41, a world traveler, and a woman who already had established a professional career.&nbsp; One doubts if Dorothy had had a husband and children whether she would ever have gone to work and spend much of the rest of her life in Nepal.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/2025071901078_68e84ade1ffb0f6c83c7f8fa5c1e7315b5f6c543217f96cde012e4d86f171515.jpg" data-media-id="editor_1" data-image-id="2025071901078_68e84ade1ffb0f6c83c7f8fa5c1e7315b5f6c543217f96cde012e4d86f171515" data-rendition-name="original" width="1259" height="910" loading="lazy" alt="How th Peace Corps changed a volunteer's life NT"> <figcaption>Pokhara Bazar in 1962.</figcaption> </figure>  The Peace Corps assigned Dorothy to teach geography at Tri-Chandra College. After the school closed in the winter due to lack of heating, USAID and the College of Education asked Dorothy to help train general science teachers.&nbsp; She taught for two months and became involved in a textbook-writing project, commenting: ‘I would like the children to know something about public health, conservation (the trees are going fast and so is the soil), and learn the names of some of their common birds, trees, and flowers. They are more impressed with electricity, airplanes, and cell structure.’ When a new college opened in Pokhara in 1963, Dorothy was transferred there and lived with a Nepali family. The college boasted 30 students and no permanent buildings.&nbsp; In October 1963, Dorothy wrote: ‘Pokhara is a town of almost 5,000 people … We are in a fertile valley surrounded by foothills … There is a small Mission Hospital … a Leper Hospital and Tibetan Refugee Camp started by the Red Cross and now run by the Swiss. With winter approaching, more Tibetans are appearing in town, often with pack horses or donkeys. Some have been carrying large boxes of powdered milk,donated (by USAID) to the camp from the airport … There is no electricity, and the transportation problems make many items scarce and expensive. I am really a sort of a museum. The landlord brings all kinds of people in to see how I live and count my shoes and dresses. They express amazement at my books, pictures, tin oven, Nepali dolls from Kathmandu, screened food shelves and curtained closet.’ The standard term for Peace Corps volunteers was two years, but Dorothy extended her term and was still at Prithvi Narayan College at the end of 1965, when she wrote that she had 20 Geography students in the first-year class and 6 in the second year preparing for the IA Examination. The college enrollment was 125 students, and the foundation for a new science building was being excavated.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/2025071901074_c6a80e5e0db0c705b2f8733c6d30dc0386fe3abbd2238ea9d947b7d746f94a29.jpg" data-media-id="editor_2" data-image-id="2025071901074_c6a80e5e0db0c705b2f8733c6d30dc0386fe3abbd2238ea9d947b7d746f94a29" data-rendition-name="original" width="902" height="605" loading="lazy" alt="How the Peace Corps changed a volunteer's life"> <figcaption>Mierow and friends at Phewa Lake.</figcaption> </figure>  Dorothy noted that she ate one meal a day at the (Shining Mission) Hospital but otherwise lived on dal-bhat, momo, and potato curry at local shops. However, she had developed a new passion: to build what she initially called the Pokhara Museum of the Himalaya. In commendable Peace Corps fashion, Dorothy always worked with Nepalis and respected the culture. ‘The greatest joy and satisfaction I have had has been from the building of a Museum-Library in memory of my parents … It has been possible to feel like a wealthy benefactor with the money saved by father for the family’s education and now available for the education of others… (Father) would have loved to be in on the founding of a new college and be able to plan a library. Several hundred of the books to be in the museum-library came from his collection and were carefully selected to be of use for students in Nepal…’&nbsp; ‘The museum part is to satisfy my own inclinations and was thought of when I found how little diversion there was for the people of Pokhara… It is part of the University requirements for the college that it should have a geography and biology museum. The museum building is small but adequate.&nbsp; I have tried to design it in harmony with Nepalese architecture and decorate it with some of the art of the best artists or woodcarvers… Posts holding up the porch roof are carved by Cottage Industries to represent different peoples of Nepal in typical costumes. The door was carved by a local wood carver and has typical birds of Nepal around it. Inside are 10 roof-support carvings designed by the retired Director of the National Museum in Kathmandu, Mr. C.M. Maskey.&nbsp; They were carved by the best wood carvers in Patan very skilfully. The building has three rooms: the library, the exhibition room, and a smaller workroom which can be used by our newly formed Woman’s Club as well as other groups or classes.’  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/2025071901074_03d3359c65389d30a0134e9a4862778994121e7e833b7d28b18e06e36fc76ff8.jpg" data-media-id="editor_3" data-image-id="2025071901074_03d3359c65389d30a0134e9a4862778994121e7e833b7d28b18e06e36fc76ff8" data-rendition-name="original" width="629" height="599" loading="lazy" alt="How the Peace Corps changed a volunteer's life"> <figcaption>Mierow with local women in Pokhara in 1969.</figcaption> </figure>  Dorothy promoted her project to influential Nepalis connected with organisations whose support she solicited: The Department of Archaeology, the Department of Agriculture, the Godavari Botanical Gardens; Tribhuvan University’s Science and Education Department, Nature Conservation Society.&nbsp; The museum was opened officially in early 1967.

Undeterred, she persuaded the college in Pokhara to invite her to return as a teacher.&nbsp; UNICEF and the Forestry Department sponsored Dorothy to prepare charts on trees, birds, animals and flowers in colour for distribution to the schools of Nepal. Dorothy, back in the Peace Corps, returned to Pokhara and the Museum in 1972. She formed a friendship with her former geography student from Sikles, Chandra Prasad Gurung, and in 1974, she brought Chandra to America, where he enrolled in Colorado College and studied cultural anthropology.&nbsp; Chandra subsequently earned his PhD in geography from the University of Hawaii and returned to Pokhara to become director of the Annapurna Conservation Area Project. Gurung actively promoted ecotourism, landscape conservation, and biodiversity conservation in Nepal.

More than 400 photos Dorothy took on treks to the Everest region, Gosaikunda, Muktinath, Jumla and Rara Lake, as well as travels in the Tarai, appeared in Himalayan Flowers and Trees (Sahayogi Prakashan, 1978).&nbsp; The botanist Tirtha Bahadur Shrestha identified the species. Dorothy and Kesar Lall published This Beautiful Nepal (Sahayogi Press, 1981). Birds of the Central Himalayas (1988) contained Dorothy’s paintings of 250 species of birds found along the areas of the Kali Gandaki River, Pokhara, Chitwan and the central Tarai. Dorothy summed up her life and work in Nepal in Thirty Years in Pokhara (Pilgrims Book House, 1997). Dorothy returned to Pokhara and her adopted Gurung family several times during the 1980s and 1990s to celebrate festivals and meet old friends. Her final years were spent at her mountain cottage in Green Mountain Falls north of Colorado Springs. She died at the age of 79 in August, 2000. Nepal gave new meaning and purpose to Dorothy Mierow’s life. Daniel W Edwards was a Peace Corps volunteer in 1966 and is the author of several books on Nepal.

· On the night of 15 May, two glacial lakes burst in Tharka in Humla and the debris flow washed away homes and bridges.&nbsp; · Last week, a slurry surge on the Kali Gandaki in Upper Mustang caused at least Rs15 million in damage, and was traced to a melting glacier. · Dozens are feared dead after <a href="https://nepalitimes.com/news/rasuwa-flood-likely-a-glof">an expanding glacial lake in Tibet overflowed</a>, sweeping down into Nepal and damaging four hydropower plants generating 230MW, nearly 8% of the country’s total grid supply.&nbsp;  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20250718060748_45225dc707c1e9c2968ca8dbf6e564e01e4eb6e2ff254fb8eb940cf62cdd910b.jpg" data-media-id="editor_1" data-image-id="20250718060748_45225dc707c1e9c2968ca8dbf6e564e01e4eb6e2ff254fb8eb940cf62cdd910b" data-rendition-name="original" width="2667" height="1500" loading="lazy" alt="Rasuwa flood"> <figcaption>Miteri friendship bridge connecting Nepal and China was swept away in the Rasuwa flood.

Recent disasters have driven up insurance premiums for energy projects in Nepal, and smaller ones cannot even afford them. The 456MW Upper Tamakosi hydroelectric project which is still not fully functional after the September floods has claimed insurance worth Rs1.8 billion. The alternative to high risk high investment hydropower projects is <a href="https://nepalitimes.com/here-now/what-s-cooking-in-nepal-besides-politics">energy diversification</a> to other renewables such as solar, wind or biogas. Nepal gets annual sunlight of 300 days with 6-7 hours on average to total 50,000 terawatt-hours (TWh) per year.&nbsp;  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20250718060744_4acd452b4117180ca9bb5d3be839ff46dfd5464e4d507f5ad3704cef6253bc48.jpg" data-media-id="editor_9" data-image-id="20250718060744_4acd452b4117180ca9bb5d3be839ff46dfd5464e4d507f5ad3704cef6253bc48" data-rendition-name="original" width="1080" height="720" loading="lazy" alt="solar power"> <figcaption>Farmers in Tarai using solar powered water pump. Photo: GHAMPOWER</figcaption> </figure>  The Solar and Wind Energy Resource Assessment (SWERA) calculates that Nepal could source 3,000MW from wind energy alone, considering 10% of the area with more than 300W/m2 wind power density. <a href="https://nepalitimes.com/opinion/people-power/decentralising-power-in-nepal">Solar energy</a> stations are cheaper and quicker to build, and would be an ideal alternative to reliance on hydropower.&nbsp; “There has been some investment in solar power, especially from the state sector,” says water expert Madhukar Upadhyay. “But there is an issue of land acquisition since the arrays need a lot of space. It is comparatively easier to get a permit to put up a hydropower plant on a river.” As for biogas, there is simply no incentive to build on past success with household level plants to <a href="https://nepalitimes.com/here-now/more-bullshit">promote industrial-scale production</a>. Scaling up biogas by integrating it with urban biodegradable waste would still be a viable alternative to LPG.&nbsp;  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20250718060744_715d44afd5eb4ba8dafa209b0ad0f19400665797b5f078f5636821e600f96684.jpg" data-media-id="editor_12" data-image-id="20250718060744_715d44afd5eb4ba8dafa209b0ad0f19400665797b5f078f5636821e600f96684" data-rendition-name="original" width="1419" height="954" loading="lazy" alt="windmill"> <figcaption>A wind mill in Hapsikot in Nawalpur. Photo: WINPOWER NEPAL</figcaption> </figure>  Nepal’s public sphere is buzzing with excitement over the discovery of potentially 430 billion cubic metres of methane gas beneath Dailekh district that, if properly harnessed, would meet the country’s energy demand for the next 50 years. Even though a feasibility study is awaited, politicians from the prime minister down see this as a petro bonanza that will make Nepal rich. But drilling, storage and distribution of CNG in the country’s current kleptocratic state make that unlikely. If Nepal was to get rich solely on its hydro-energy potential, it could have done so in the past 50 years. Says Dhungel: “This is not exactly a new discovery, but it is premature to celebrate until its extraction is proven to be cost effective. And let us hope it does not get <a href="https://nepalitimes.com/news/balance-of-power">tangled in geopolitics</a>, since China is involved in the prospecting and drilling, which could make India uneasy.”&nbsp; The country suffers from the Dutch Disease curse even before its resource is fully exploited. And the same cronyism, corruption and rent-seeking structure cannot deliver the riches we expect from Dailekh’s methane discovery. Now, <a href="https://nepalitimes.com/here-now/right-climate-for-nepal-s-energy-transition">with hydropower in jeopardy</a>, Nepal’s planners will have to evolve a new strategy for energy security into the future. But first, governance needs to be cleaned up with long-term strategic planning that takes climate risk into account. For example, do we need to mine fossil gas when there are renewable options? Will Dailekh take Nepal away from its climate commitments? Says Madhukar Upadhyay: “Nepal has always been resource rich and management poor. And the larger the resource, the bigger our management incapacity. It is a societal malaise.”&nbsp;

Nepal’s Resource Curse

Nepalis are living longer than ever. By 2028, the country is set to join the ranks of other <a href="https://nepalitimes.com/news/nepals-demographic-window-is-closing">ageing societies</a> around the world, and by 2054, 1 out of every 7 people in Nepal will be over 65. Life expectancy at birth has risen dramatically from just 55 in 1990 to 71 today, &nbsp;thanks to improvements in public health and access. But as more people live longer, the country must also prepare for a parallel rise in age-related illnesses and the complex social and medical needs that come with an <a href="https://archive.nepalitimes.com/article/Nepali-Times-Buzz/need-to-prepare-for-ageing-society,3624">ageing population</a>. Extended families have always acted as a safety net for <a href="https://nepalitimes.com/news/home-sweet-home-for-older-nepalis">the elderly</a>, with children and grandchildren shouldering most caregiving duties. But with more than 1,600 <a href="https://nepalitimes.com/banner/migration-not-a-wish-but-necessity-for-nepalis">Nepalis migrating </a>every day, older parents are left behind with no one to care for them. <a href="https://nepalitimes.com/editorial/the-new-equaliser">Remittances</a> from migrating youth, which account for nearly a third of Nepal’s GDP, have kept the economy afloat. But money sent home cannot make up for the chronic departure of kin and caregivers, who are often the first to catch the signs and symptoms of disease in elders. In rural areas where over 85% of Nepal’s elderly live, the absence of this daily vigilance means early signs of illness often go unnoticed until they become debilitating. As a result, chronic conditions like hypertension, diabetes, and depression are left unmanaged.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20250720130748_213f2c65f2638872e9ac0550a7ac251e4960c3726dc5c76215962a23ba71dff1.jpg" data-media-id="editor_5" data-image-id="20250720130748_213f2c65f2638872e9ac0550a7ac251e4960c3726dc5c76215962a23ba71dff1" data-rendition-name="original" width="1064" height="701" loading="lazy" alt="Smart ageing is Nepal’s next frontier"> </figure>  Geriatric medicine is largely absent from medical curricula and there is no national plan in place to manage cognitive decline, memory loss and confusion. These are often mistaken for signs of normal ageing, instead of <a href="https://archive.nepalitimes.com/article/nation/dementia-brings-new-problem-that-families-have-little%20knowledge-of,2151">dementia</a>, delaying care until it is too late. The same pattern plays out with strokes, osteoarthritis, and vision problems — conditions that could be managed early but are instead allowed to spiral into <a href="https://nepalitimes.com/opinion/comment/changing-disability-to-this-ability-h68f6sq2">disability</a>. Nepal is not ready for an older future. It needs a strategy for ‘smart ageing’ where the focus is not adding years to life, but enhancing years lived through the intelligent application of policy, infrastructure, and crucially, <a href="https://nepalitimes.com/opinion/comment/tech-and-transition-in-nepal">technology</a>. Many models of smart ageing, however, are sculpted around modern societies where independent living in later life is the norm. Furthermore, eroding traditional family care and an underdeveloped formal care system means there is a large gap that can’t simply be filled by copy-pasting from foreign models. Nepal must shape its own version of smart ageing. The <a href="https://nepalitimes.com/news/healthcare-moving-from-hospitals-to-homes?%2F">tech boom</a> has led to homegrown digital healthcare apps such as Hamro Doctor, Cura Health, Jeevee and Health Yaad Ayo which offer teleconsultations, online appointments, and at-home test bookings. As <a href="https://nepalitimes.com/review/nepal-s-new-digital-landscape">smartphones and internet access</a> extend to the most rural fringes of the Nepali countryside, geography is no longer a barrier to the use of these digital tools. What limits their use is the lack of digital proficiency among the older generation. Others find the idea of turning to a device instead of a familiar, reassuring face unfathomable. That is why <a href="https://nepalitimes.com/opinion/addressing-nepals-digital-divide?ref=blog.togglecorp.com">digital literacy</a> efforts must be paired with guided human support to build trust alongside technical skill. Such a model of community-led digital mediation is already gaining traction elsewhere. In the UK, ‘digital health ambassadors’—often young people or even schoolchildren—are trained to co-design and advocate for online platforms that resonate with peers who might otherwise feel excluded from automated health services. A Nepali version could engage cohorts of nursing students, tech-savvy youngsters and returnee migrants to assist elders in navigating digital health platforms and troubleshooting problems, and most of all, normalising the idea of health apps being a reliable recourse.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20250720130748_fcb94ab76e76b5574189757e88d76fccad4e115e78dd9eae92a3bd4c882c3431.png" data-media-id="editor_12" data-image-id="20250720130748_fcb94ab76e76b5574189757e88d76fccad4e115e78dd9eae92a3bd4c882c3431" data-rendition-name="original" width="2246" height="1590" loading="lazy" alt="Smart ageing is Nepal’s next frontier"> </figure>  Nepal’s own network of Female Community Health Volunteers (FCHVs), whose credibility is rooted in long-standing relationships across rural communities, could be similarly upskilled, their roles in <a href="https://nepalitimes.com/here-now/target-2030-for-maternal-and-newborn-health">maternal and child health </a>expanded and repurposed to also include geriatric tech support. However, there is a limit to how much older adults can adapt to new technologies. So, Nepal should simultaneously invest in passive technologies—tools that monitor and act for the elderly, instead of demanding active use. That is where wearables and in-home smart health devices collectively known as 'gerontechnology' come in. Picture an 82-year-old in far-flung Rolpa, away from the facilities of an urban hospital. Installed in her home are low-cost motion sensors that monitor prolonged inactivity or signs of a fall, instantly triggering alerts to the nearest health post when necessary. On her wrist, a wearable bracelet continuously tracks her sleep, vital signs, oxygen saturation, and glucose levels. This data is encrypted and synced to a digital dashboard accessible by health staff at the local post. If the system flags an acute risk—such as a potential stroke or hypoglycemia—a nearby health worker is dispatched immediately to her home. If her readings over time indicate a trend toward a <a href="https://nepalitimes.com/news/why-do-so-many-nepalis-have-high-blood-pressure">chronic condition</a> like diabetes, community health volunteers step in. They help schedule a virtual consultation with an endocrinologist in Butwal. Based on the advice received, she gets a prescription and picks up her medication from the local community pharmacy, along with a smart dispenser to ensure she sticks to her treatment plan without missing doses. This is not as far-fetched as it may sound. Many of the individual devices forming this connected medical system called an Internet of Medical Things (IoMT) already exist in Nepal as imported commercial products. What is missing is a stronger framework for <a href="https://nepalitimes.com/business/public-health-partnership">public-private collaboration</a>: one where health tech companies continue developing locally adapted tools, and the government actively integrates these innovations into public health delivery. <a href="https://nepalitimes.com/opinion/people-power/nepal-as-an-ai-power-bank">Nepal’s tech ecosystem</a> is maturing, but policymaking must evolve in tandem, especially when it affects an older generation largely resistant to change. The backlash against the recent mandate requiring National Identity Cards for accessing social security benefits revealed the pitfalls of imposing top-down reforms without adequate preparation or support for seniors. For Nepalis to age well, community caregivers, doctors, innovators, and above all, the state, must step in where families have stepped away. The goal is not to replicate traditional care, but to build a coordinated system of support that connects everyone through technology. The future is older for Nepal, let us be wiser too.

Smart ageing is Nepal’s next frontier

चौतारा rest stops have long been an integral part of scenic touristic town of <a href="https://nepalitimes.com/news/pokhara-six-decades-ago">Pokhara </a>but are now rarely seen as the city bursts at the seams. They say inhabitants of Pokhara saw a plane before they saw cars. Indeed, the grass airfield was built in the 1950s, while the Kathmandu highway 20 years later. Before roads, people walked to get around, pausing to rest or even nap under the shade of banyan-pipal trees. <a href="https://nepalitimes.com/here-now/pokhara-s-desperation-and-hope">Pokhara airport’</a>s ‘terminal’ in those days was a shady chautara where passengers waited for their flights. The chautara bore silent witness to daily life, whether it was travellers seeking a brief respite from the summer heat or villagers gathering for a chat in the mornings and evenings. But with the roads came vehicles, and then houses started filling up spaces, even farmlands. Pokhara began transforming from a serene village to a <a href="https://nepalitimes.com/news/pokhara-comes-alive-at-night">bustling city</a>.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20250719010724_d101fa482441ce67afdf5bc4e4547b334e7662c1cf0a20e9d31a0e8dff66f04b.jpg" data-media-id="editor_3" data-image-id="20250719010724_d101fa482441ce67afdf5bc4e4547b334e7662c1cf0a20e9d31a0e8dff66f04b" data-rendition-name="original" width="2147" height="1581" loading="lazy" alt="Trees of life and living NT"> <figcaption>Photo: DURGA RANA MAGAR</figcaption> </figure>  The banyan-pipal trees were chopped down to make way for wider intersections and buildings. The once-iconic rest stops that carried Pokhara’s identity had all but vanished. “Building chautara was once considered a religious duty, which is why so many of them were constructed across Pokhara,” says archivist Sunil Ulak. <a href="https://archive.nepalitimes.com/news.php?id=10927">Ekai Kawaguchi</a>, a Japanese Buddhist monk, who visited Nepal 120 years ago en route to Tibet, documented <a href="https://nepalitimes.com/banner/no-visitors-in-pokhara-to-admire-view">the landscape of Pokhara</a> and its surroundings. In his book, Three Years in Tibet, he reflects on the natural beauty of the town and its shady trees. A chautara used to be surrounded by ponds, where shepherds would bring their cattle to drink from while they took a nap under the shade. The gentle rustling of leaves in the cool breeze lent a soothing melody as did the chirping of birds, while the insects took refuge in the branches and leaves. Read also: <a href="https://nepalitimes.com/here-now/pokhara-800-years-ago">Pokhara 800 years ago</a>, Kunda Dixit This ‘nature’s breeze’, as botanist Kalyan Panta puts it, is now history due to <a href="https://nepalitimes.com/banner/cost-of-living-in-a-big-city">haphazard urbanisation</a>. “When the wind strikes against one leaf, it creates a domino effect and other leaves start waving as well,” he explains. There were 632 chautara in the city until 1977, and by 2000 the number had fallen to 278. But in some wards the number of trees fell from 55 in 1984 to only five now.&nbsp; The gradual loss of these resting places has meant habitat <a href="https://nepalitimes.com/banner/between-existence-and-extinction-in-nepal">destruction of birds and insects</a>, it has also damaged the environment and natural beauty of the city.&nbsp; Researcher Jagannath Adhikari’s study showed that infrastructure projects ignored the environment, and concluded that that urbanisation in Pokhara was unsustainable.&nbsp; The destruction continues to this day. Recently, old chaurata in wards 6, 13 and 14 were cleared to make way for a sacrificial ritual. In fact, ward 6 got a permit from the local government to clear its remaining trees.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20250719010724_cee1d4faf8376e7ba18b9c7012ea4215b7c3fbf7e0983b0c97005df5567d6de0.jpg" data-media-id="editor_9" data-image-id="20250719010724_cee1d4faf8376e7ba18b9c7012ea4215b7c3fbf7e0983b0c97005df5567d6de0" data-rendition-name="original" width="1500" height="1000" loading="lazy" alt="Trees of life and living NT"> <figcaption>Photo: DURGA RANA MAGAR</figcaption> </figure>  But in wards 13 and 14, the Human Service Foundation cut down some 33 trees for which it is in a dispute with the metropolitan city as there is no unclear jurisdiction regarding who gives the permit. The Kaski Division Forest Office is currently investigating the matter. Elsewhere in ward 19, the ward office had launched ‘मेरो रूख, म काट्छु’ campaign due to an alleged chaos caused by monkeys in the area. The decision was rescinded after an all-around opposition.&nbsp; To be sure, there are policies in place to protect trees such as the Gandaki Province Forestry Act, 2080, and the Regulations, 2081. The province government also introduced an act in 2019 per which no tree, including pipal, silk cotton and other <a href="https://nepalitimes.com/opinion/suburban-tales/trees-trees?%2F">trees of natural and historical importance</a> shall be damaged, eroded or removed. But the local government, responsible for implementing the Act, is doing the opposite. “If this rapid rate of tree felling continues, neither trees nor chautara will survive for the future generation,” conservationist Ram Bahadur Poudel tells us, adding that old trees are being cleared under the pretext of pruning branches. Interestingly, Ulak notes that Pokhara-8 was called सिमलचौर in the past because there were so many majestic silk cotton trees, but there are very few left, if any, and hence altering the identity of a place. With modernisation, people have questioned the significance of chautara in this day and age. But they still have relevance. Urban centres in Pokhara and Kathmandu are much hotter than the outskirts because of the <a href="https://nepalitimes.com/news/in-the-heat-of-the-moment-5xcycyot">urban heat island effect</a>. Says archivist Ulak: “While their original purpose was to provide rest, today they continue to play a crucial role in regulating temperature, beautifying the city, and preserving our environment.”
