Of the at least 573 stone spouts once counted in Kathmandu Valley, many are lost, damaged, or no longer functional due to neglect, pollution, and encroachment of ponds and canals that feed them.

Kathmandu’s liquid landscape

Jhuma Limbu used to wake up at 3AM every morning to queue up for water from a municipal tank in her neighbourhood of Patan. In the dry season, she got home three hours later carrying a jar of water. But this spring, Limbu and her neighbours have been pleasantly surprised that a 700-year-old water spout across the road is gushing water even in the dry season. Usually, the hiti water spout used to have water only during the monsoon months from July to September. “It was so amazing to see the sparkling clean water flowing continuously,” an elated Limbu told us as she filled her plastic jar at the spout with the alligator-like मकर mythical animal carved on it. “I don’t know why there is water this season, but it has made my life a lot easier,” she added.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20230512040524_b589e897fc0e54fbff99556629fdc59dfc4bd31f744c080ba8c8a014752293f0.jpg" data-media-id="editor_0" data-image-id="20230512040524_b589e897fc0e54fbff99556629fdc59dfc4bd31f744c080ba8c8a014752293f0" data-rendition-name="original" width="3500" height="2219" loading="lazy" alt="Water for the ages NT"> <figcaption>Photos: SUMAN NEPALI</figcaption> </figure>  The Misa and Kwanti Hiti spouts at Baglamukhi Temple in Patan have religious and cultural significance. A ritual is performed for the spout and it attendant monks every July when the फूद्योः (supreme being) is transported to the temple amidst much fanfare. Devotees then bathe in the sacred waters of the sunken spout. Elsewhere in Patan, water spouts like Mang Hiti, Chhayabaha Hiti, Chyasa Hiti and Narayan Hiti are now better maintained and fully-functional even in the dry season.

Even though water from Melamchi is supplied through the mains on a rotational basis, it has meant that families are not using traditional wells to draw water as much, allowing the water table to rise and make the spouts flow again.&nbsp; “If the Valley’s population continues to increase and extraction of well water resumes, the water table will fall again and the spouts will go dry,” explains Joshi. “It is crucial that we come up with a plan to ensure perennial water supply at the hiti.”&nbsp; <a href="https://www.nepalitimes.com/news/saving-nepal-s-hiti-heritage">Ancient water spouts </a>are considered great technological achievements of the Kathmandu Valley Civilisation.

Centuries after they were built, these systems still support the growing urban population of Kathmandu Valley because modern water mains are so unreliable. But unplanned urbanisation of Kathmandu in recent decades has threatened this historic network of sunken spouts. Many water sources have been buried by construction, ponds that used to recharge ground water have been built over. The underground channel that used to bring water to spouts have been destroyed, like the one supplying Sundhara in Patan which was damaged during the construction of the nearby Employees Provident Fund building.

Says Joshi: “Because 80% of rain falls in three months, we can store monsoon runoff in recharge pits and make use of existing wells for storage as well.” A new system of channels is being built to amplify the water flow to Patan’s water spouts from a distribution centre in Khumaltar, and it is set to come into operation in a few months. Says Chandra Kumar Shrestha of the municipality’s Project Implementation Directorate: “If water supply from Melamchi is more regular, it will help recharge ground water and revive our dry hiti and benefit more people.”  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20230512040524_ae12c7503ea6717c4a727a1c14a500f964e0e86668f9f923950cfb8a6c907d81.png" data-media-id="editor_8" data-image-id="20230512040524_ae12c7503ea6717c4a727a1c14a500f964e0e86668f9f923950cfb8a6c907d81" data-rendition-name="original" width="890" height="677" loading="lazy" alt="Water for the ages NT"> </figure>  <h2>“Respect our ancestors by saving the hiti they built.”</h2> Padma Sundar Joshi In the last 30 years, many hiti in Patan and elsewhere in the Valley have gone from being perennial sources of water to becoming completely dry. First, the flow of water decreased. Then the water began to flow only during the monsoon, before stopping altogether. Unregulated construction because of the Valley’s population density destroyed both the sources of water as well as the underground channels connecting water sources to the ancient hitis.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20230512040524_e4682485318176545ed0a48df78f49d3b3290deacf0b4e9d4825042d76f5de49.jpg" data-media-id="editor_9" data-image-id="20230512040524_e4682485318176545ed0a48df78f49d3b3290deacf0b4e9d4825042d76f5de49" data-rendition-name="original" width="1250" height="1563" loading="lazy" alt="Water for the ages NT"> </figure>  People in the valley began drilling tube wells to ensure water supply, but this lowered the water table and dried up the hiti. Now, with the Melamchi water supply, many of those wells are not used as much. This, in turn, has meant that the water table has risen, reviving the flow in the ancient spouts even in the dry season. However, if Kathmandu Valley’s population continues to grow at an unprecedented rate, it won’t matter how much water is supplied from Melamchi, Yangri, or Larke. There simply will not be enough water. Managing urban growth must be the priority. A hiti’s age is often cited as the reason for it going dry, but that is not the case. The Mangal Hiti in Patan has been providing water continuously for 1,500 years. How long a hiti has existed is immaterial as long as it is managed and protected. And that means not only making the sunken spouts more attractive, but to strengthen its functionality.&nbsp;  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20230512040524_f53c479374835cbe2814c4b6fafcde48073208c6cceab23446761f2f61755529.jpg" data-media-id="editor_10" data-image-id="20230512040524_f53c479374835cbe2814c4b6fafcde48073208c6cceab23446761f2f61755529" data-rendition-name="original" width="3000" height="2000" loading="lazy" alt="Water for the ages NT"> </figure>  A key to making water flow again in the <a href="https://www.nepalitimes.com/here-now/water-of-the-ages">Valley’s hiti </a>is to bring back the recharge ponds and lakes which have been built over. But conservation of our ancient water supply system has been neglected because it is deemed too expensive. In fact, water should be an election agenda, and elected leaders must fulfil their promises.&nbsp; The good news is that many of our hiti have been flowing again, even in the dry season. This reminds us that heritage and nature conservation go hand in hand, both must be protected.&nbsp; Kathmandu’s hiti define our civilisation and our place in history.

The system takes advantage of elevation difference for natural purification and a controlled flow of water based on gravitational force alone.“Considering that 70% of the terrain in Nepal is mountainous, the geography of the hills and valleys is naturally suitable for a water supply technology that depends on gravity alone, not requiring the input of any form of external energy,” explains civil engineer and researcher Hrishav Raj Joshi. “This was leveraged to its fullest when our ancestors designed the hiti system more than 1,500 years ago.”This indigenous technology reached its peak during the Lichhavi period (ca. 200-879 CE). The Mallas (1200-1769 CE) largely expanded the hiti system.  One of the oldest documented hiti, Mani Hiti in Mangal Bazar, built in 570 CE by an influential Bharavi, is still functioning today with very little maintenance and human intervention.<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221114101140/63720db29c7e80680e0b78dajpeg.jpg" alt="" width="4032" height="3024"><figcaption> </figcaption></figure><figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221114101140/63720db69c7e80680e0b78dbjpeg.jpg" alt="" width="4032" height="3024"><figcaption> </figcaption></figure>Sushil Shrestha, who has two decades of experience in restoring hiti and ponds, explains why the system lasts many centuries, with minimal cleaning and minor periodic maintenance requirements.He says, “All components of the hiti system were built using locally available skills and materials like soil, wood, bricks and stone. This ensured self-sufficiency, sustainability and longevity.”The builders applied an ingenious biological intervention to keep the channels and spouts running sustainably over centuries.  The drainage, when blocked, was cleaned with live frogs and snakes were sent down the narrow drains, and their wriggling motion as they forced their way out of the lower end of the drain, would clear up the obstruction.<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221114101140/63720db99c7e80680e0b78dcjpeg.jpg" alt="" width="14042" height="9934"><figcaption> </figcaption></figure><a href="https://www.nepalitimes.com/banner/restoring-rest-houses-to-revive-culture/">Public open spaces</a> played an important socio-cultural role in Kathmandu's urban fabric.

Kathmandu’s ancient water spouts still functioning

<figure><img width="640" height="427" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221109141116/636ba8779c7e80680e0737e2jpeg.jpg" alt=""/><figcaption>Photo: SONIA AWALE</figcaption></figure>Haphazard urbanisation, a continually growing population and long delays in the finalisation of the Melamchi Project have resulted in an increasing water scarcity in Kathmandu Valley. But these are not new issues. What is new is that they have become the subject of renewed discussion during the Covid-19 outbreak. The state authorities have repeatedly told people over the last few months to reduce transmission of the virus by washing their hands ‘properly’ (michimichi), scrubbing with soap and water. That this is very difficult to do without easy access to water. Also, this new demand for water comes on top of the usual requirement for safe drinking water and water for other household uses. Most residents of Kathmandu Valley own or rent small dwellings, and only a few are able to find the space for a storage tank on the roof, in the garden or underground. More than 70% of the Valley’s population relies on piped underground water sources officially maintained by the local authorities. Just before the monsoon started this year, the Kathmandu Upatyaka Khanepani Limited (KUKL) was distributing piped water once every 11 days. When the monsoon is over in a month the situation will become acute. Last year’s annual report of the agency shows that the average water supply, after deduction of the 20% losses through leakage, is 103mld/day (million litres per day) as against the total requirement of 430mld/day. Kathmandu has only a quarter of water that is needed (see chart). <figure><img width="512" height="408" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221109141116/636ba8799c7e80680e0737e3jpeg.jpg" alt=""><figcaption>Source: KUKL 2018-19</figcaption></figure>Kathmandu Valley has been suffering from a shortage of water, especially drinking water, since at least the 1980s, and the situation has been getting worse year by year. Policy-makers, engineers and others consider the <a href="https://archive.nepalitimes.com/page/melamchi-coming-to-kathmandu">Melamchi Water Supply Project</a> as the long-term solution. The project was designed to divert fresh water to Kathmandu Valley from the <a href="https://www.nepalitimes.com/here-now/light-at-the-end-of-the-melamchi-tunnel/">Melamchi River in Sindhupalchok District</a> through a 26km tunnel to Sundarijal. Work on the scheme started in 1998 and it is still under construction, having suffered innumerable delays owing to problems with lending agencies, contractors, and corruption, and, most recently an accident in the tunnel that killed two staff.  When completed, the Melamchi project will be able to supply about 170 mld/day of water, but this will not meet even current demand, let alone future requirements. Since the state utility has not been able to meet water demand, people have come to rely on alternative sources, including wells and boreholes. An  increasing number of households now purchase water as a matter of course from commercial water tankers or, for drinking water, buy plastic jars. Some still rely on <a href="https://archive.nepalitimes.com/article/nation/renew-commitment-to-preserve-ancient-water-spouts,2931">‘traditional’ sources</a>, such as springs, wells and rivers, water spouts or tanks. Many of these underground water sources, however, <a href="https://www.nepalitimes.com/here-now/water-of-the-ages/">have been damaged by the development of urban infrastructure</a> and extraction of underground water on an unprecedented scale in the past three decades.  The <a href="http://archive.nepalitimes.com/article/Nation/water-table-of-kathmandu-valley-falling-fast-recharge-to-replenish,4100">unregulated extraction of underground water</a> by both private operators and KUKL, has lowered the groundwater table. Similarly, new construction has reduced the open spaces that would allow recharge of the water table. One consequence is the destruction or degradation of traditional water systems that have dried up stone spouts and wells that had served the people of the Kathmandu Valley for hundreds if not thousands of years. This water supply system in Kathmandu Valley can be traced back at least to the Licchavi era more than a thousand years. It was not built during a single regime, but gradually improved upon over the centuries. It is only in recent times that it is threatened. <img width="650" height="573" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221109141116/636ba87a9c7e80680e0737e4jpeg.jpg" alt="">The major source of water for the stone spouts was the <a href="http://archive.nepalitimes.com/news.php?id=9129#.X0yYDSgzaUk">raj kulo (Royal Canal)</a> which started from the foothills on the Valley rim, and fed into ponds which stored and <a href="https://www.nepalitimes.com/opinion/nepal-must-keep-water-on-its-land/">recharged water for the aquifers</a>, which were themselves largely dependent on rainwater. A single stone spout may have had a single or multiple sources of water. Many were fed by either an individual spring or a local aquifer. Some sunken spouts were fed by shallow aquifers using percolated surface water, others were located near or far from a source. A single aquifer might supply water to a single spout, or to multiple spouts serving a number of communities. Water was channelled through burnt clay or wooden pipes to the stone spouts through passages so that the water could flow easily. Most of the stone spouts had a base platform to capture discharged water, and a drain it through the side which served to supply another stone spout downstream, or irrigate nearby farms, before finally flowing into a river.  When the springs and other water sources went dry and the water level in  shallow aquifers went down, the stone spouts also discharged less water or became dry. In this way, a complex and heterogeneous system was gradually developed over the centuries that utilised water from different sources, channelled it, often over considerable distances, and discharged it eventually through the spout, acting as a tap, for use by local communities.Centuries after they were built, water from these sources are still being used by households, hotels, restaurants, factories and tanker operators, for laundry, personal hygiene and cleaning vegetables. Residents fall back on the traditional systems when there is not enough available water from the government piped system. However, the water is not potable anymore.It is late, but not too late, however, to recognise the potential value of these systems with their multiple water sources, complex distribution channels and stone spouts. With proper conservation, they continue to supply much needed water to people of the Kathmandu Valley, in addition to maintaining an important archaeological heritage and the rich cultural associations of these living monuments, particularly for the Newa people whose forebears built them.   https://www.youtube.com/watch?v=RggblppqixsSince people in Kathmandu Valley still use these water sources for cleaning, washing, bathing, irrigation, they could play an important role by integrating them with modern technologies. Water from these historical systems could contribute to a sustainable solution to the Kathmandu Valley’s increasing water scarcity. The first pre-requisite is that there is no interruption in the water’s source, route and eventual outlet at the spouts by new physical infrastructure. An effective system needs to be devised for adequate water storage in reservoirs or tanks to maintain water supply throughout the year. Along with storage, the water must also be treated appropriately. If these prerequisites are met, water from these age-old spouts could be easily accessible, of good drinking quality, and be free of cost. Given the right storage, the spouts can supply water continuously, complementing the official piped water system or public water tankers -- particularly for low income households which cannot afford to buy water.   <figure><img width="1379" height="748" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221109141116/636ba87c9c7e80680e0737e5jpeg.jpg" alt=""><figcaption>Iku hiti where water from stone spout is still being used for drinking, bathing, washing and cleaning. Photo: RIISHTA SHRESTHA</figcaption></figure>One working example of just such an outlet with a viable storage system is Iku Hiti in Dhobighat of Lalitpur, where water from the sunken spout flows into a storage tank of 80,000 litres operated by the KUKL, and distributed to people in the nearby communities. Shree Krishna Dongol of KUKL says water is distributed to communities every alternate day from 5AM- 6.30AM, in addition to its own supply which is once a week. Water supply is extended to 9AM-12.30 and 2-4PM during the monsoon. The same pipe is used at homes to distribute water from both the sources and the communities pay according to the meter fixed by KUKL at their homes. The management committee also charges Rs5 / jar for those who collect water for restaurants or hotels. Families pay less, and those who live near the area do not pay at all. The money is used for cleaning and maintenance of the stone spout and its premises. The committee is also constructing a separate pond to wash clothes so that the stone spout area can be clean and safe. <figure><img width="1378" height="689" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221109141116/636ba87f9c7e80680e0737e6jpeg.jpg" alt=""><figcaption>Washing facility at the Iku Hiti with water from the spout. Photo: RISHTA SHRESTHA</figcaption></figure>There are grounds to justify serious initiatives and additional efforts by state and local authorities, non-state entities, private organisations and local communities, to protect, rehabilitate and renew these traditional water supply systems, and to ensure their survival and maintenance, so that they can, once again, meet the needs of the modern residents of Kathmandu Valley. <a href="http://archive.nepalitimes.com/regular-columns/GUEST-COLUMN/positive-alternatives-to-federalism,350">David Seddon</a> has undertaken research and consultancy on development issues in Nepal over several decades.Ranjan Prakash Shrestha, PhD,  has research experience in climate change and indigenous knowledge and practices related to urbanisation and sustainable water resource management.

Solution to Kathmandu’s water crisis

Walkabout with Anil: Hiti

The irreplaceable loss of Kathmandu Valley’s historic hitiThe ancient trade route between India and Tibet cut diagonally through Kathmandu’s city core. At its northern edge was the historical gateway to the city through which Newar merchants passed on their way to and from Lhasa.Today a yellow concrete-and-glass commercial block stands on the spot just northwest of Rani Pokhari. The structure was built right on top of Jhanga Hiti, the ancient sunken spout that stood there till 35 years ago. “This was the spot where families bid tearful farewell to the merchants when they left on perilous journeys across the Himalaya to Lhasa. There is no trace of this historic landmark today,” explains tourism expert Gyanendra Ratna Tuladhar. The Tibet trade thrived for centuries until the Chinese annexation in the 1950s.Considered one of the greatest technological achievements of the Kathmandu Valley civilisation, hiti are traditional stone water spouts built inside conduit basins below the ground level, where drinking water flowed non-stop. The water was piped through underground channels made of Gathu Cha, a type of water-tight clay. <figure><img width="640" height="853" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221104141140/636516cc9c7e80680e02c239jpeg.jpg" alt=""/><figcaption>Pic 1.

This intricate network of water channels helped the valley’s kingdoms to thrive and support urban populations.Today, many of these hiti have dried out due to underground waterways being blocked by rampant construction and other infrastructure. <figure><img width="640" height="427" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221104141140/636516d19c7e80680e02c23bjpeg.jpg" alt=""><figcaption> </figcaption></figure>When Jhanga Hiti went dry, locals forgot about its historical importance, and when piped water became available it was covered over and converted into prime real estate.A  local football club then laid claim to the land, and eventually obtained permission to build its club house on top of Jhanga Hiti in 1981, permanently burying its glorious history. The lower floors of the building are now rented out to shops, while the football club has offices and a meeting hall on the upper floors.Some 80m to the south is where Bhotahiti was discovered 4m below the surface in 1984 during the construction of an underpass. Water was still flowing from the spout when it was unearthed. The spout dates back to 621 CE and was originally called Vanta Hiti (Eastern Spout).<img style="max-width:100%" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221104141140/636516d49c7e80680e02c23cjpeg.jpg">Bhotahiti was among seven water spouts in the area, and was first buried during the construction of Tundikhel in the 1880s. The underpass construction went ahead, and Bhotahiti was filled over a second time.The lower portions of the basin of Tindhara Hiti at the southern end of Darbar Marg is still moist with ground water today. Local apathy and official neglect have turned the historic waterspout into a wasteland.Engineering student Rohit Nepali studied Kathmandu’s 7th century Gairidhara, 2 km east of Darbar Marg, and says it dried up only a few years ago when large buildings went up in the vicinity.  <figure><img width="640" height="427" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221104141140/636516d69c7e80680e02c23djpeg.jpg" alt=""><figcaption> </figcaption></figure><figure><img width="640" height="427" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221104141140/636516d99c7e80680e02c23ejpeg.jpg" alt=""><figcaption> </figcaption></figure>“We must study and fully understand the physical structures that were built with very little technical resources compared to today, during the Licchavi and the Malla periods, before they all disappear,” Nepali says.Despite many hiti in Kathmandu going dry or filled over, there are still a handful of these historic spouts that provide water to this day to communities in Kathmandu, Patan and Bhaktapur.Maru Hiti is one of them, and it lies at the opposite southern end of the ancient trade route that once bisected Old Kathmandu. Crystal clear drinkable water still flows out of its ornate stone spout day and night.Alok  Siddhi Tuladhar  is a culture and heritage documentarian.

Water of the ages

On Tuesday, leader of the monarchist RPP once again gathered on Kathmandu’s streets to deliver fiery speeches, but this time there was no arson and looting and no need for riot police to fire live rounds or tear gas.
RPP leaders demanded the release of their members including vice-president Rabindra Mishra and MP Dhawal Shamsher Rana were arrested during the violent <a href="https://nepalitimes.com/news/republicans-and-royalists-on-nepal-s-streets">28 March protests at Tinkune </a>which left two dead. 
They denounced the current leadership of the main parties, demanding the <a href="https://nepalitimes.com/editorial/nepal-party-reincarnating-hindu-monarchy">restitution of Nepal as a Hindu kingdom</a>. They also said the government was responsible for the fatalities on 28 March because it provoked its rally with a tear gas attack even before it started.
It has now been revealed that the police fired at least 100 live rounds from high powered assault rifles at the crowd. Twenty-one of the 120 injured received bullet wounds, and most of them were bystanders and people trying to reach home. 
Tuesday protest on the Ring Road in Balkhu was much more subdued, and comparatively fewer RPP supporters showed up. The arson and vandalism in the previous protest appears to have cost some support for <a href="https://nepalitimes.com/news/the-ghost-of-monarchy-returns-to-haunt-nepal">former king Gyanendra </a>especially for the anointment of medical tycoon and bank defaulter <a href="https://nepalitimes.com/news/street-politics">Durga Prasai </a>as ‘commander’ of the Tinkune rally.
Some monarchists acknowledge Gyanendra’s mistakes when was king 2001-2008, but say he has had a lot of time to reflect on his shortcomings and seems more disciplined and committed. His supporters have tried to build on nostalgia among some Nepalis for<a href="https://nepalitimes.com/news/why-invest-in-nepal"> domestic stability </a>and international respect that <a href="https://nepalitimes.com/here-now/if-birendra-was-alive-nepal-could-still-be-a-monarchy">the monarchy</a> commanded. 
“Nepalis were promised better service delivery, opportunities for the underserved, as well as better, more honest use of state resources, but the <a href="https://archive.nepalitimes.com/news.php?id=16992">people in leadership </a>have not been able to deliver on their commitments,” says RPP leader Prakash Chandra Lohani. “The gap between their rhetoric and reality has widened, the people feel betrayed, and the respect Nepali people had previously had for them has changed to revulsion.” 
Indeed, many commentators have warned the three main parties and their <a href="https://nepalitimes.com/editorial/politics-as-usual">serial prime ministers</a> who have ruled Nepal for much of the past 30 years should address rising public anger with them, and see the writing on the wall.
‘<a href="https://nepalitimes.com/news/nepal-government-changes-again">The UML, NC and Maoists</a> must introspect about their conduct,” warns Gunaraj Luitel, editor of Nagarik, in an op-ed this week. ‘These leaders for life may save themselves from simmering public anger, but they will not be able to save the system. The monarchist wave can only be dispelled when citizens are assured of <a href="https://nepalitimes.com/here-now/nepal-s-local-election-gives-power-back-to-people">better governance</a> through <a href="https://nepalitimes.com/latest/real-world-training-for-youth-leaders">younger leaders</a>, and reforms.’ 
Rifts between radical royals who are gunning for a return to <a href="https://nepalitimes.com/here-now/mob-movement-and-mayhem">Panchayat-style absolutism </a>and moderate monarchists who favour a constitutional king have also weakened the movement somewhat. The split between the RPP and RPP-Nepal cost the royalists numbers in Parliament in 2022, and both parties denounced the violence last month, albeit shifting the blame on the government.
The irony is that the same royalists who want to scrap the republican Constitution had formed electoral alliances with the UML during the 2022 elections. RPP-Nepal chair Kamal Thapa contested the 2022 election with the UML. Thapa has not taken part in the last two rallies, saying he will only be a part of a movement under a national flag, and not a RPP party banner.
For his part, the RPP’s Rajendra Lingden is said to be hesitant to censure some of his party’s more radical royalists for fear of fissure within his ranks, despite his aversion to Durga Prasai’s role. 
Analysts have questioned why <a href="https://nepalitimes.com/news/old-is-still-gold-in-nepali-politics">supporters of the monarchy </a>have decided to reestablish an institution that would not ultimately have executive decision-making power. There are doubts about whether authoritarian-minded Gyanendra will be satisfied being a <a href="https://archive.nepalitimes.com/news.php?id=13957">ceremonial king</a>.

"The Nepali people will not accept <a href="https://nepalitimes.com/here-now/forgotten-woman-who-sheltered-communist-activists">an absolute monarchy </a>at this point of time, and both the public as well as <a href="https://archive.nepalitimes.com/news.php?id=8371">king Gyanendra</a> are fully aware that there is no other possibility beyond a constitutional monarchy," asserts the RPP’s Lohani. “The traditional monarchy’s institutional capacity might have been enough to meet the needs of feudal Nepal, but an absolute monarchy is impossible both in concept and practice in the context of <a href="https://archive.nepalitimes.com/regular-columns/Economic-Class/waiting-for-an-industrial-revolution,784">modern day Nepal</a>.”

The theme of World Health Day on 7 April this week was ‘Healthy Beginnings, Hopeful Futures’ dedicated to <a href="https://nepalitimes.com/opinion/comment/saving-more-mothers-and-babies">preventing maternal and newborn deaths</a>. It is estimated that in Nepal, 30% of neonatal mortality can be blamed on air pollution. But that is only part of the story. Harmful as fine particulate matter is to human health, carbon monoxide, nitrogen dioxide, ground-level ozone and other gases in vehicular emissions are more hazardous to health. While the concentration of suspended particulate matter tinier than 1.5 microns (PM2.5) is closely monitored, these toxic gases are invisible, not measured much, and the public is not aware about the dangers they pose. Surface ozone is produced by the interaction of various gases found when <a href="https://nepalitimes.com/news/fossil-fuels-poison-air">burning fossil fuels</a>. Besides being poisonous, ground level ozone contributes up to 0.23°C to <a href="https://nepalitimes.com/here-now/nepal-s-mountains-are-melting">global warming</a> because it is also a greenhouse gas. A new policy brief by the Clean Air Fund titled The Case for Action on Tropospheric Ozone blames surface ozone for a half a million premature deaths every year, 54.8% of which are in South Asia. Ozone also stunts plant growth and reduces crop yields by 26% globally, and 11% loss in <a href="https://nepalitimes.com/news/economic-benefits-of-saving-the-ecology">forest productivity</a>, the report adds.&nbsp;  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20250411060456_aa02a923f8b27544ae54d0220162678f5bbb5eeb8fc3c466173c22c49b3e9a85.jpg" data-media-id="editor_11" data-image-id="20250411060456_aa02a923f8b27544ae54d0220162678f5bbb5eeb8fc3c466173c22c49b3e9a85" data-rendition-name="original" width="998" height="724" loading="lazy" alt="Gas Chambers"> </figure>  Read also: <a href="https://nepalitimes.com/here-now/bad-air-and-polluted-politics">Bad air and polluted politics</a>, Sonia Awale Ground-level ozone is not emitted directly into the air like other gases, but is formed when oxides of nitrogen (NOx), carbon monoxide (CO) and volatile organic compounds (VOCs) released from automobile tailpipes or industry smokestacks react chemically with each other in the presence of sunlight. The main source of carbon monoxide in Kathmandu Valley are its 1.2 million two-wheelers. “Usually the concentration of carbon monoxide is 200-500 parts per billion (ppb), this has increased up to 3,000 in Kathmandu. Meanwhile, ground-level ozone has gone from 70-80 ppb to 150 ppb,” says Ravi Sahu, regional air quality specialist with the Kathmandu-based International Centre for Integrated Mountain Development (ICIMOD).&nbsp; Sahu says <a href="https://nepalitimes.com/news/no-smoke-without-fire-p7vb9dcj">rampant forest fires of the past weeks</a> have also added to carbon monoxide and ozone in the air, not just the fine particles that make up the visible smoke. He adds, “There isn’t much awareness about <a href="https://nepalitimes.com/banner/poisoning-the-air-we-breathe">ground-level ozone and carbon monoxide</a>, we need to urgently look into it.” A distinction must be made between good and bad ozone. Stratospheric ozone protects living beings from harmful ultraviolet (UV) radiation from the sun.&nbsp; Tropospheric ozone can again be separated into two types: ozone in the free atmosphere which is a greenhouse gas much more potent than carbon dioxide, and ground-level ozone which has adverse impacts on health and agriculture. ‘Cutting tropospheric ozone presents a unique challenge as it requires smart and fast action across multiple greenhouse gases and air pollutants, as well as multiple economic sectors,’ notes the Clean Air Fund's policy briefing. ‘It is a growing and neglected problem that needs an integrated approach on both a local and global level to tackle climate change and air pollution together.’ Dying young There was a time when Nepal made it to international news bulletins only if there were fatalities on Mt Everest. Now, Kathmandu’s bad air frequently makes headlines all over the world. This past week, the concentration of PM2.5 that harms human health was up to 40 times the WHO recommended guideline — adding to the poisonous gases already present from vehicle emissions. The Department of Environment says 40% of the pollution in the past weeks was from wildfires sparked by nearly 6 months without substantial rain over central Nepal. Most of the rest is from vehicular and industrial emissions from Kathmandu itself and across the southern border. NASA’s Fire Information and Resource Management System (FIRMS) which issues daily maps of fires, showed hundreds of blazes raging across Nepal on Wednesday, mainly in Chitwan, Parsa and along the East-West Highway.&nbsp; “If we look at the figures for the last few years, it is clear that wildfires have become the biggest source of air pollution, they are seasonal but have overtaken vehicular emissions,” says urban planner and environmentalist Bhushan Tuladhar. “Forest fires, stubble burning, and open burning of garbage are the bigger problems now. Nepal, India, Bangladesh, and Pakistan are at risk every year, we shouldn’t further delay in finding solutions,” warned air quality expert Bhupendra Das during an event on air pollution organised on 7 March by the Nepal Forum of Environmental Journalists (NEFEJ).&nbsp; Indeed, studies have shown that in winter 60% of the air pollution over Kathmandu is transboundary from the south, and in November it is compounded by smoke from crop residue burning by farmers in India and Pakistan blown in by prevailing winds. Forest fires are a regular pre-monsoon occurrence in Nepal, often intentionally set by farmers and herders to stimulate new grass growth for livestock. Winter rains have failed for eight of the past ten years, and this means the fires often spread out of control. The other reason for the increase in wildfires is the doubling of forest fires to 46% of the country’s area in the past 25 years. But this has happened simultaneously with outmigration, with some mountain districts losing 30% of their population between 2011-2021. With less pressure on forests for fodder and firewood, the undergrowth of community forests is loaded with dry fuel just waiting for a spark. The bowl-shaped topography of Kathmandu, Pokhara and other valleys further concentrates pollutants as they are trapped by surrounding mountains. But a year with a high number of wildfires is usually followed by a year or two with fewer incidents. For example: there were 6,537 fires in 2021 but the following year the number was down to 1,528. There were 5,216 fires last year, this year the number has already reached 1,800, and the trend is likely to be broken. Heavy rains forecast for the coming days are expected to douse some of the fires and clean up the air. But the damage has been done: Kathmandu residents of all age groups this week crowded clinics and hospitals with burning eyes, itchy throats, difficulty breathing, headaches, and dizziness. But in the longer term, soot particles that are tiny enough to jump the blood-air divide in lung capillaries do not just cause Chronic Obstructive Pulmonary Disease (COPD), asthma, but also cancers, heart attacks, strokes, birth defects and other chronic diseases. The latest Air Quality Life Index (AQLI) report by the University of Chicago shows that the annual concentration of PM2.5 in Kathmandu’s air rose from 17.87µg/m3 in 1998 to 31.33µg/m3 in 2022. Air pollution has got worse by 75% in Kathmandu in 25 years. During this time, air pollution has reduced the average life expectancy of Kathmandu’s residents by 3.5 years. According to the Health Effects Institute in Boston, dirty air is among the biggest public health concerns in Nepal killing over 42,100 a year. The adverse impact of high levels of air pollution is not limited to public health, it is seriously affecting tourism. Operators in Pokhara this week said that there were many negative online posts by visitors unable to see the famous panorama of Machapuchre and the Annapurnas even from Sarangkot. Aviation is also affected, as planes have to circle sometimes for hours burning a lot of fuel because of runway visibility being below minima at Kathmandu airport. The higher fuel cost is just passed down to customers, making air tickets in and out of Kathmandu some of the highest in the world. Kathmandu, with a population of four million, has not implemented a concrete policy to curb toxic air despite having formulated various action plans and repeated commitments by the government to protect the environment and control air pollution. The Department of Environment’s 2017 Air Quality Management Action Plan for Kathmandu put forward a policy to reduce air pollution caused by vehicles which was approved by the Cabinet, but has yet to be put to practice. The action included the immediate implementation of the Euro 5 emission standard to reduce pollution emitted by vehicles. However, Nepal has not even been able to implement Euro 4 standards so far. India, meanwhile, has already moved forward with the implementation of the Euro 6 standards. Says Ravi Sahu: “Air pollution in Nepal is not just about air pollution, it has ties to tourism, aviation, the economy so we must be prepared for annual conditions like forest fires, and this requires urgent interdisciplinary collaboration.” &nbsp;  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20250411050452_821d09e283d8a590f1369bfb71b9b7fc6d950726e0651ea86c6488d04deb1742.jpg" data-media-id="editor_15" data-image-id="20250411050452_821d09e283d8a590f1369bfb71b9b7fc6d950726e0651ea86c6488d04deb1742" data-rendition-name="original" width="839" height="784" loading="lazy" alt="Silent Killers"> </figure>  &nbsp;

What is invisible is more dangerous

82 in २०८२

Here in the mountains of far-western Nepal, the biggest threat to life and limb is gravity. Women collecting fodder fall from trees, boys grazing goats fall off cliffs, heavily loaded tractors plunge from dirt roads carved out of steep slopes. There is nothing to be done about those who die on the spot. But for the severely wounded there is only one hospital: Bayalpata. And it is there that <a href="https://www.youtube.com/watch?v=CJzWlnYd0ZM&amp;t=8s" target="_blank">orthopaedic surgeon Mandeep Pathak</a> is the last hope for many wounded people. Pathak, 42, is too modest to tell us how many lives he has saved over the past 10 years he has worked at Bayalpata. But hospital records show he has performed more than 4,000 operations in the past decade, many of them so patients did not suffer permanent physical disabilities. Pathak also did 800 major life-saving surgeries in that time. “I treat patients with injuries, but I wish I could also treat poverty,” Pathak says, emerging from Bayalpata’s surgical theatre one recent afternoon. <div class="embed-block"><iframe width="700" height="415" src="https://www.youtube.com/embed/CJzWlnYd0ZM?si=s_rkbU4YDaw87gqH" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen></iframe></div> Sudurpaschim Province in Nepal’s far-west is far away from everything: from Kathmandu, from adequate medical care, from food security, and far from the reach of government services. It has suffered state neglect for centuries, its men mainly migrating to India for seasonal work to families who depend on subsistence agriculture. Pathak remembers the searing sadness he felt when a patient once told him, “Doctor, I sold the last of my rice to pay to come here, please give me a medicine that I can take on an empty stomach.” Pathak was born in Kathmandu, and after getting his MBBS from Kathmandu University, he got an MD from The Philippines. At a time when many Nepali doctors and staff nurses were emigrating, Pathak did not just return to Kathmandu but decided to go to one of the remotest districts in Nepal to serve those most in need. The hospital was established in 2009 in the village of Bayalpata, and has been managed by the non-profit <a href="https://www.nyayahealthnepal.org/" target="_blank">Nyaya Health Nepal (NHN)</a> as a public-private partnership treating 100,000 patients a year for no fees at all. NHN is now preparing to hand over the running of the hospital to the Sudurpaschim provincial government so its <a href="https://nepalitimes.com/banner/this-is-how-to-upgrade-nepals-rural-health" target="_blank">model of hospital management</a> can be replicated.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20250414130456_b59dabd4604a24426a55fe91c0e5866b5029858bdb4c4028c331557aeb5408ae.jpg" data-media-id="editor_4" data-image-id="20250414130456_b59dabd4604a24426a55fe91c0e5866b5029858bdb4c4028c331557aeb5408ae" data-rendition-name="original" width="1500" height="1000" loading="lazy" alt="Bayalpata hospital"> <figcaption>Bayalpata hospital in Achham.</figcaption> </figure>  People from not just Achham but surrounding districts, and from as far away as Humla, bring patients to Bayalpata, sometimes walking for days. Some with complicated pregnancies are brought in stretchers, young children with broken arms walk into the emergency, and sometimes there are mass casualties when a tractor or bus falls off a road. And Pathak is always there with his team performing triage, and doing orthopaedic surgeries that would be difficult even in Kathmandu. Recently, his team did a hip replacement at <a href="https://nepalitimes.com/banner/state-of-the-art-rural-hospital" target="_blank">Bayalpata Hospital</a>. Mild mannered, modest, soft-spoken, hard-working, professional are the words families of patients who have been treated at <a href="https://nepalitimes.com/here-now/nepal-s-rural-lifeline" target="_blank">Bayalpata Hospital </a>use to describe Mandeep Pathak. But the surgeon is too busy to let all this get to this head.&nbsp; Asked why he does not emigrate like his peers or get a lucrative position at a private hospital in Kathmandu, Pathak answers simply, without a trace of self-importance, “I do not think I could get the satisfaction or sense of fulfilment anywhere else.” When travelling to attend medical congresses overseas or visit family in Kathmandu, Bayalpata has other doctors to take care of patients, but many wait patiently till Pathak returns for their consultation or surgery.&nbsp; When he returns from seminars abroad after learning the latest skills, Pathak’s suitcases are not full of clothes or presents, but titanium bone implants, external fixation rods, or intramedullary nails to be used in <a href="https://nepalitimes.com/news/altruistic-healthcare-models-in-nepal" target="_blank">surgeries at Bayalpata</a>.&nbsp;  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/2025041414040_5356278472c1eb2b9e4af1d593d6234cc8dc5e5161a8c614197c01abefadbd80.jpg" data-media-id="editor_8" data-image-id="2025041414040_5356278472c1eb2b9e4af1d593d6234cc8dc5e5161a8c614197c01abefadbd80" data-rendition-name="original" width="2048" height="1368" loading="lazy" alt="surgery"> </figure>  Before Bayalpata Hospital was established, most people suffering broken bones had to travel down to Dhangadi or Nepalganj for treatment. No more. Although Pathak’s specialisation is orthopaedic oncology, he is mostly treating fractures and rejoining broken bones.&nbsp; Now as Bayalpata’s Hospital Director, Pathak also has administrative and fundraising duties. He has to take the 10-hour ride down to Dhangadi often to meet various Sudurpaschim ministries to release the hospital’s budget — that is sometimes more difficult than the most complicated surgery. Recently, he had to cancel an appointment with the Chief Minister to rush back to Bayalpata because there was a patient who needed emergency surgery. “I told myself, let me save this patient first, then I will try to save the hospital,” he recalls.&nbsp; Once, when he had to be away for a month on emergency surgery training in the US, the family of a 90-year-old woman who had dislocated her hip after falling from a staircase was waiting for him to return. Her son told Pathak: “Doctor, either put her out of her suffering, or cure her.” Pathak told him it was too dangerous to operate at her age, but the son said his mother was in so much pain it was worth the risk. The operation was touch-and-go, but it was successful. The woman who had been brought in on a stretcher, walked out of the hospital three days after the operation.&nbsp; A few months later, a 27-year-old woman was brought into the ER bleeding profusely from an arm mangled by a thresher machine. Even in that state, she was breastfeeding her baby. Pathak welled up seeing this display of selfless motherhood, as he wheeled her into surgery. She needed three operations, but now has full use of her hand. <div class="embed-block"><iframe width="700" height="415" src="https://www.youtube.com/embed/xJdxLD0hBqo?si=mOpM2R_DsYL88Lfg" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen></iframe></div> It is the sense of achievement from such recovery that keeps Mandeep Pathak here in this isolated village in the middle of nowhere. Bayalpata Hospital has not just saved lives, it also saves families from poverty because they do not have to take sick relatives to expensive city hospitals.&nbsp; In January, a woman was brought to Bayalpata with both hands broken. She said she had taken a fall, but Pathak did not believe her. When alone in the surgery, she finally admitted that her husband had beaten her.&nbsp; It was her husband who had brought her to hospital for treatment, but she refused to file a police report. Pathak quietly put both her arms in casts, thinking about the poverty, patriarchy and injustice in society that he is unable to treat.
