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.

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.

A dozen students fleeing a school below were injured while escaping, and there were reports of widespread livestock loss. Excessive post-monsoon snowfall could have contributed to the avalanche, which also resulted in flooding on a tributary of the Kali Gandaki.</figcaption></figure>Hazards in the Himalaya do not queue up politely to occur one at a time. More often, they occur together and, when they do, their cumulative effect is greater than the sum of their parts. When floods and landslides happen at once, for instance, the impact of each is intensified by the other. Still, it remains common to approach risk reduction for each hazard individually. In Nepal, and the wider Himalayan region, the coincidence of multiple hazards necessitates a multi-hazard approach to disaster risk reduction.At best, considering one hazard at a time is wishful thinking. At worst, single-hazard approaches reduce the risk of one hazard only to increase the risk from others. To avoid these tradeoffs, a multi-hazard approach manages the connections between hazards to reduce overall risk. Shifting perspective from single- to multi-hazard risk may appear subtle, but our recent research shows the stakes are high. Our team studied three dominant hazards — floods, landslides, and wildfires — and found that many Himalayan residents live in areas highly susceptible to more than one of them. If other hazards (like drought, heat stress, or earthquakes) were added to our study, it is likely that the population exposed to multi-hazards would be even higher. The predictions made by hazard models can vary considerably and their results depend especially on which set of previous hazards they consider, but the message emerging from this research is clear: Since many people in the Himalaya live in multi-hazard environments, managing one hazard at a time could have disastrous consequences. <figure><img width="2501" height="1332" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/2022111016114/636d133e9c7e80680e0a9912jpeg.jpg" alt=""><figcaption> </figcaption></figure>Importantly, adopting a multi-hazard approach does not mean making things more complicated. Instead, it can identify synergies to address them together, while providing a basis for collaboration for aligning single hazard management and governance practices that could otherwise conflict. A multi-hazard approach is relatively new, but multi-hazards themselves are already here. They can take many forms. Sometimes, one hazard causes another: In 2015, the Mw 7.8 Gorkha earthquake caused thousands of landslides and claimed thousands of lives. Or, in February of this year, a <a href="https://www.icimod.org/article/understanding-the-chamoli-flood-cause-process-impacts-and-context-of-rapid-infrastructure-development/" data-saferedirecturl="https://www.google.com/url?q=https://www.icimod.org/article/understanding-the-chamoli-flood-cause-process-impacts-and-context-of-rapid-infrastructure-development/&amp;source=gmail&amp;ust=1637032361315000&amp;usg=AOvVaw1TMfOVKuNvXo6wVNvXAAsm">rockslide triggered massive flooding</a> in the Chamoli district of Uttarakhand, claiming over 70 lives and damaging multiple hydropower projects. Other times, hazards happen together. For example, this year’s monsoon season caused <a href="https://www.nepalitimes.com/banner/nepal-valley-suffers-quadruple-disaster/" data-saferedirecturl="https://www.google.com/url?q=https://www.nepalitimes.com/banner/nepal-valley-suffers-quadruple-disaster/&amp;source=gmail&amp;ust=1637032361315000&amp;usg=AOvVaw0GCEQeMHKILrZSwBGgTR4n">destructive flooding and landslides</a> in many districts in Nepal (the effects of which were exacerbated by the ongoing pandemic). Without causing another hazard directly, one hazard can worsen the effects of another, such as last year’s widespread forest fires in Nepal that denuded hillsides, <a href="https://www.nepalitimes.com/latest/monsoon-hits-nepal-with-a-bang/" data-saferedirecturl="https://www.google.com/url?q=https://www.nepalitimes.com/latest/monsoon-hits-nepal-with-a-bang/&amp;source=gmail&amp;ust=1637032361315000&amp;usg=AOvVaw0jHHk_D84gbE7XCdXxb9ld">making the slopes more prone to landslides, mudflows, and flooding</a>. Other threats loom on the horizon. The latest report by the UN Intergovernmental Panel on Climate Change (IPCC) makes it clear that climate-related multi-hazards will become more common and more intense in the future. Glacial lakes at risk of outburst flooding are growing due to climate change, while changing precipitation patterns could make both seasonal flooding and forest fires more frequent and destructive. These changes interact in complex ways, raising the overall threat from multi-hazards. As climate change intensifies multi-hazards, current patterns of urbanisation will continue to put more people in harm’s way. Our research shows a high level of settlement in areas also prone to multi-hazards; people may be unaware of multi-hazard risk, or immediate concerns for their livelihood overrule potential future risk from catastrophic multi-hazards. In either case, people settle in multi-hazard-prone areas to access economic, healthcare, or educational opportunities. Thus, an important component of reducing risk is in providing sustainable livelihoods in less risky areas. Impoverished people in multi-hazard areas may not have the resources necessary to recover from disaster or to settle in safer areas if those areas have lower levels of access.  <figure><img width="1500" height="1000" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/2022111016114/636d13419c7e80680e0a9913jpeg.jpg" alt=""><figcaption> </figcaption></figure>Gender disparities increase risks to women, and religious minorities may not have equal access to disaster preparedness resources in some places. Multi-hazards are natural events with human effects. Thus, beside technical and governance issues, a multi-hazard approach should consider how multi-hazards multiply the risks faced by already vulnerable populations.With a multi-hazard approach, synergies are possible. For instance, <a href="https://www.iucn.org/sites/dev/files/content/documents/bioengineering_brochure_hr.pdf" data-saferedirecturl="https://www.google.com/url?q=https://www.iucn.org/sites/dev/files/content/documents/bioengineering_brochure_hr.pdf&amp;source=gmail&amp;ust=1637032361315000&amp;usg=AOvVaw2Lq1Jfzk5Xb_CeV6qBLNbk">soil bioengineering</a> is an established set of techniques in Nepal that focuses on conditions — vegetation, drainage, and sediment — that contribute to multiple hazards. By focusing on the conditions where hazards intersect, practices like bioengineering could be more suitable for a multi-hazard environment than those that focus on reducing the risk of a specific hazard alone.Without a multi-hazard approach, reducing the risk from one hazard could increase the risk of another. In the wake of this year’s fire season, for example, unvegetated buffers around developed areas may seem like a good option for preventing fire damage to structures. But these areas more easily erode, potentially contributing to landslides or mudflows. Similarly, slope stabilisation to prevent landslides, especially around road cuts, can increase surface runoff and exacerbate flooding. Engineering approaches are important, but multi-hazard risk reduction is not just a technical problem. Governance issues are at the root of both major opportunities and challenges for mitigating multi-hazard risk. A significant obstacle to adopting a multi-hazard approach is existing mandates for governing bodies to manage single hazards in isolation. For example, federalisation in Nepal gave the Ministry of Home Affairs the mandate to manage forest fire risk, but the mitigation of floods and landslides, which interact with forest fires, often remains at the municipal level. These divisions can lead to conflicts between agencies, while a multi-hazard approach can align mandates otherwise focused on single hazards. Nepal’s Disaster Risk Reduction Strategic Action Plan is already taking steps in this direction.  <figure><img width="4940" height="3965" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/2022111016114/636d13449c7e80680e0a9914jpeg.jpg" alt=""><figcaption> </figcaption></figure>In addition to managing connections between hazards, governance practices aimed at reducing multi-hazard risk can facilitate two other forms of collaboration: across borders, and between people, residents and otherwise, with different forms of expertise.First, current collaboration across borders in the Himalaya should be expanded and strengthened. Both hazards and people cross borders, so multi-hazard mitigation must do the same. This last summer, for instance, a landslide-dammed lake in the Rongxer basin in China <a href="https://www.icimod.org/article/the-melamchi-flood-disaster/" data-saferedirecturl="https://www.google.com/url?q=https://www.icimod.org/article/the-melamchi-flood-disaster/&amp;source=gmail&amp;ust=1637032361315000&amp;usg=AOvVaw2EsX51_SbSWuFjpxRyRC6D">threatened Nepali settlements downstream</a> along the Tama Kosi River with flooding. Further along the same river, <a href="https://www.nepalitimes.com/banner/the-kosis-sorrow-and-scope/" data-saferedirecturl="https://www.google.com/url?q=https://www.nepalitimes.com/banner/the-kosis-sorrow-and-scope/&amp;source=gmail&amp;ust=1637032361315000&amp;usg=AOvVaw0D5xTZ_9lCZdd17ab60kVm">sedimentation in Nepal is one of many factors</a> contributing to downstream flooding in Bihar, India. The establishment of cross-border early warning agreements is an important way to reduce these risks and is a first step toward connecting upstream and downstream risk reduction through a multi-hazard approach.Second, the collaboration between people with different types of knowledge about hazard risk — including technical, development, and local experts — is essential for ensuring the success of risk reduction programs. An inspiring precedent for this kind of collaboration is the development of <a href="http://archive.nepalitimes.com/article/nation/Recharging-the-mountains,3465" data-saferedirecturl="https://www.google.com/url?q=http://archive.nepalitimes.com/article/nation/Recharging-the-mountains,3465&amp;source=gmail&amp;ust=1637032361315000&amp;usg=AOvVaw0m8l5RSFN5WSy2wB1oMXhv">jholmal</a> natural fertiliser and pesticide. The development of jholmal required combining local practices with the work of technical specialists and efforts to reduce chemical runoff and farming costs to create a cost-effective formula easily communicated to and replicated by the region’s residents and other local experts. This collaborative and multi-pronged approach can serve as model for mitigating multi-hazard risk. A focus on multi-hazards does not contradict the need to reduce the risk associated with individual hazards; instead, a multi-hazard approach is an opportunity to align risk reduction measures to avoid tradeoffs and find synergies. Adopting a multi-hazard approach may present technical or governance challenges but the opportunity is clear: in the face of ongoing climate change and urbanisation, effective disaster risk reduction in environments such as Nepal, the Himalaya, and other mountainous regions necessitates a multi-hazard approach.Jack Rusk is a member of the <a href="https://urbanhimalaya.yale.edu/" data-saferedirecturl="https://www.google.com/url?q=https://urbanhimalaya.yale.edu/&amp;source=gmail&amp;ust=1637032361315000&amp;usg=AOvVaw1cdFH8tcfgFtKCY-vVpPAE">Urban Himalaya</a> research team.

Waves of mud washed away the highway and bridges connecting the site, submerged settlements, and killed at least 30 people.The much-delayed <a href="https://www.nepalitimes.com/here-now/light-at-the-end-of-the-melamchi-tunnel/">$800 million project</a> had started test distribution of water from the Langtang National Park through <a href="https://archive.nepalitimes.com/page/melamchi-coming-to-kathmandu">a 26.5km tunnel to Kathmandu</a> residents. Fortunately, the tunnel had been sealed for inspection a few hours before the flood hit that day, and was saved.<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110141152/636d02a99c7e80680e0a3691jpeg.jpg" alt="" width="1013" height="562"><figcaption> </figcaption></figure>Geologists and experts are now trying to study the upper reaches of the Melamchi watershed to determine what caused the <a href="https://www.nepalitimes.com/latest/the-monsoon-mess-in-melamchi/">disastrous debris flow</a>, and to see if anything can be done to mitigate future floods. What they found does not bode well.Project engineers say that the two big floods in July caused damage worth more than Rs2 billion, including a 22km link road, 6 bridges, warehouses and offices. Six project staff from Nepal, India and China were killed.“Melamchi is now uncertain, we do not know when we can restart the project,” says senior divisional engineer Rajendra Prasad Pant. “We need to make a much more extensive study of the watershed upstream to determine if we can control future floods, and if so how long it will take.”Indeed, aerial inspection and satellite imagery of the Melamchi Valley upstream shows a massive sediment field that is constantly collapsing and being washed down by heavy monsoon downpours.<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110141152/636d02ab9c7e80680e0a3692jpeg.jpg" alt="" width="815" height="410"><figcaption> </figcaption></figure><figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110141152/636d02ad9c7e80680e0a3693jpeg.jpg" alt="" width="907" height="640"><figcaption> </figcaption></figure>Engineers say they are trying to mobilise heavy earthmovers to clear the debris and send water into the tunnel again through a temporary channel by the end of the year to resume water supply to Kathmandu. Just this part of the job will add another Rs1 billion to the cost of the project.But there remains the enormous challenge of dealing with the 2.5km long crumbling sediment field upriver, which they say will pose a danger for decades to come. No one has an estimate of how much any mitigation measures will cost, or if it is even possible.But besides immediate repairs at the headworks, the disaster has also put on hold the second and third phase of the project, which was to extend the tunnel to Yangri and Larke, two parallel valleys to the east to augment the tunnel capacity by another 340 million litres per day.Although engineers had studied the upper reaches of the Melamchi to scope out any glacial lake or unstable slopes, they had never expected the sediment field to be so fragile and unstable.“So far, we think the disaster was caused by record rainfall in the catchment area which had been destabilised by the 2015 earthquakes,” says Shiva Baskota of the Department of Mines and Geology, who recently flew over Bhemthang region, and said he saw extensive slope failure on the Melamchi and its tributary stream, the Pemdang.<figure><figcaption>Aerial photo of the confluence of the Melamchi and Pemdang Rivers taken after the 30 July flood.</figcaption></figure><figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110141152/636d02b29c7e80680e0a3695jpeg.jpg" alt="" width="960" height="640"><figcaption> </figcaption></figure>Baskota estimates that some 150 cubic metres of fluvial, glacial or lacustrine deposits still sit on the river upstream at an elevation of 3,500m, and this is constantly being washed down by the river because of continuing heavy rains. On 11 July, <a href="https://www.nepalitimes.com/here-now/nepal-needs-weather-stations-in-the-himalaya/">a weather station</a> in nearby Sermathang recorded <a href="https://www.nepalitimes.com/latest/monsoon-hits-nepal-with-a-bang/">110mm of rain in 24 hours.</a>Some scientists blame the <a href="https://www.nepalitimes.com/banner/disasters-in-nepal-come-in-waves/">extreme weather events</a> on climate change, and say that heavy downpours are now falling on higher altitudes where there used to be snowfall. Other researchers believe that in addition to heavy rainfall, a glacial lake higher up could have burst, adding material to the debris flow.“It looks like there has not been an adequate disaster risk assessment of the catchment area,” Baskota says. “This means we have to study the glaciers above Yangri and Larke before starting the next phase of the Melamchi water project.”There is a way to reduce the danger from future flooding along the Melamchi by building check dams along the river to slow the flow of the debris. But engineers admit it is a huge and expensive undertaking which has to start as soon as the monsoon ends to be prepared for next year’s rains.Climate scientist Raju Pandit Chhetri says that the <a href="https://www.nepalitimes.com/editorial/a-hotter-himalaya/">impact of global warming</a> in the Himalaya is only going to increase, so current and future infrastructure along the mountains have to take the risk into account.“Bridges, highways, water supply all have to be designed to withstand extreme events,” says Chhetri. “It may drive up the cost of the project, but it will prevent greater loss. Planning for a disaster like this would not have affected the Melamchi project as badly as it did.”<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110141152/636d02b59c7e80680e0a3696jpeg.jpg" alt="" width="853" height="640"><figcaption> </figcaption></figure>Some water experts say that an expensive project like Melamchi should never have been built in the first place, when cheaper alternatives to <a href="https://www.nepalitimes.com/latest/nepal-needs-to-plan-for-plenty-and-scarcity-of-water/">supply water</a> to Kathmandu through reservoirs on the Valley rim to store monsoon water was possible.“Even back then, some of us had warned that Melamchi was not suitable,” says water scientist Ajaya Dixit. “We had not foreseen a disaster like the one this year, but we knew that Sindhupalchok’s rugged terrain made it a risky place to invest in expensive infrastructure.”Government officials, however, say that although the Norwegian consultants of the Melamchi project had assessed seismic and environmental risk and designed it for a lifespan of 100 years, nothing like the flood in July was ever expected.“What was perhaps not factored in was the new risk added by accelerated global warming,” says Pant.A British consultant had conducted a study in 1988 of rivers in and around Kathmandu Valley to select the most suitable river for a project to augment the Valley’s water supply, and Melamchi was chosen as the most appropriate on the basis of flow, natural gradient and proximity.<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110141152/636d02b89c7e80680e0a3697jpeg.jpg" alt="" width="853" height="640"><figcaption> </figcaption></figure>The Melamchi project was thus launched with support from the Asian Development Bank (ADB), but it was delayed due to political interference, local opposition, earthquakes, blockades, pandemic and other upheavals.The project therefore took three times longer than it should have and was inaugurated only on 4 April 202`1 by President Bidya Devi Bhandari. Households and businesses in Kathmandu felt a great sense of relief that the water had finally arrived, but within three months the flood damaged the project and taps went dry again.In the Ministry of Water Supply, there is already talk of finding alternative sources of water for the Valley even if Melamchi is restored – because of the continued flood risk on the river, and the fact that the project will not be able to satisfy the thirst of an expanding capital.At present the water utility for Kathmandu supplies between 90-170 million litres to consumers every day from existing reservoirs, streams and groundwater. Melamchi had doubled that supply, but it still did not meet demand. Pumping groundwater has also lowered Kathmandu’s water table, and that supply is dwindling.Adapted from the <a href="https://www.himalkhabar.com/news/125894?fbclid=IwAR2I5UufeaISdu2Osxb8Yp0FpurIImwHwavx02htF_C_HPokMEICh3TV3Rw">Nepali original</a> in the September-October edition of Himal Khabarpatrika.

Six highway bridges, and 12 suspension footbridges have been swept away. The $700 million Melamchi Water Supply Project has been damaged even before it came into full operation, and will need expensive and extensive repairs. Basanta Adhikari, Associate Professor of Engineering Geology has just returned from an inspection visit, and spoke to Nepali Times.Nepali Times: From your trip, what appears to be the main cause of this continuing flood?Basanta Adhikari: Due to the weather we could not fly to the headwaters, but looking at videos, it seems that there was always a large amount of glacial and fluvial debris accumulated at a place called Bhremathang. Since the<a href="https://www.nepalitimes.com/banner/after-the-deluge-in-nepal/" target="_blank" rel="noopener noreferrer"> muddy flood</a> is continuous, I am certain it cannot only be attributed to the landslide on 15 June that blocked the river. All that debris that had accumulated is being constantly washed down.  How much debris are we talking about? And what is it made of? That calls for more study. But there seems to be a multiple thick layer of sand, mud and boulders that have been brought down from the mountains and collected in a relatively flat area. It is also possible that thousands of years ago, a landslide blocked the Melamchi, leading to an accumulation of sediment in what is now a dried up lake bed. Besides this, this could also be part of a glacier that has receded. These are all just possibilities, nothing can be said for sure until further research is done. <a href="https://www.nepalitimes.com/editorial/a-hotter-himalaya/">A hotter Himalaya</a>, Editorial <figure><img width="233" height="277" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110141124/636cfc569c7e80680e0a0b82jpeg.jpg" alt=""><figcaption>Basanta Adhikari</figcaption></figure>How long will there be a risk of more floods threatening the Melamchi project headworks and downstream valleys?  Looking at the debris field there, it is likely that the effect will be quite long-term. Every time there is heavy rain, the loose boulders and sand will keep being washed down. The debris accumulation has to be thoroughly studied before we can say anything about its long-term effects. Only after studying the volume of the debris field can we predict how long it will affect downstream areas. Research Is also needed to design mitigation efforts.Is there a way to stop the flood upstream so it does not threaten the <a href="https://www.nepalitimes.com/latest/nepal-needs-to-plan-for-plenty-and-scarcity-of-water/" target="_blank" rel="noopener noreferrer">Melamchi project</a>?We cannot top the flow where the debris field is currently located. However, if we build  a series of check dams, the danger from floods can be reduced. There is sufficient technology and manpower to do so, but it all depends on whether the government has the political will and the funding to carry it out. If preventive measures are taken in time, threats of future catastrophes can be minimised.What lessons can we learn from the Melamchi flood? We must thoroughly analyse what lies upstream before we design any infrastructure or settlements. What are the potential dangers? What can be done to safeguard against future disasters? When planning  large-scale projects like Melamchi, we should model the potential for natural disasters, and engineer them accordingly.

The monsoon mess in Melamchi

Nepal’s only international aviation gateway, at Kathmandu airport, will cut night-time operation hours to allow construction of taxiways, and airlines have been told to curtail flights. This is expected to lead to more than normal chaos during the height of peak autumn and spring tourist seasons at an airport that is congested even at the best of times. The airport will close from 10PM to 8AM from 8 November-31 March 2025. The taxiways will now connect to the thresholds at both ends of the runway, making the airport more efficient in handling higher frequencies of landings and takeoffs. The parallel taxiway extension will allow international flights to land every 4 minutes instead of the current every 7 minutes. At present planes have to wait to land until a plane taking off backtracks along the runway.&nbsp; Kathmandu is Nepal’s only airport with international operations, and it has only one runway that is only one way in from the south over the mountains. With the taxiway improvement, the airport will be able to handle 42 aircraft landings and takeoffs per hour — double the current capacity.&nbsp; The Civil Aviation Authority of Nepal (CAAN) has been trying to entice international airlines to also start flying to and from the other two international airports at Pokhara and Bhairawa (Lumbini) by slashing landing and handling charges. But so far only Nepal Airlines operates a weekly flight to Bhairawa from Kuala Lumpur.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20241018161016_046569e53d1d66cd445cc66c697c0ef724810aec9f54bdf827481e3cd6b80c32.jpg" data-media-id="editor_0" data-image-id="20241018161016_046569e53d1d66cd445cc66c697c0ef724810aec9f54bdf827481e3cd6b80c32" data-rendition-name="original" width="2356" height="1134" loading="lazy" alt="Kathmandu airport expansion"> <figcaption>Kathmandu Airport Expansion plan with extension of taxiways to the thresholds of runways 02 and 20 that will limit airport operations from 8 November 2024 - 31 March 2025.

Many airlines currently operate regular flights to and from Kathmandu between 10PM and 8AM: Air Arabia to Sharjah, Fly Dubai to Dubai, Jazeera Airways to Kuwait, Cathay Pacific to Hong Kong, Singapore Airlines, several Nepal Airlines flights, and one of four daily flights by Qatar Airways to Doha. Jazeera Airways, FlyDubai, and Thai AirAsia have applied and got permission from CAAN to begin regular flights to Bhairawa’s Gautam Buddha International Airport. Starting 9 November, FlyDubai will start making a stopover in Bhairawa before flying on to Kathmandu. Immigration, customs and security are all fully functional in Bhairawa. In Kathmandu, the next phase of the airport upgrade includes converting the current international terminal for domestic operations, the construction of a new international terminal where the domestic departure area is now, as well as moving the hangars and the Nepal Army Air Wing to the eastern side of the runway. The apron area will also double its parking space for widebody jets. This is part of a Airport Capacity Enhancement Project that was initially funded through a $80 million loan from the Asian Development Bank (ADB), and the entire masterplan is expected to cost $800 million. This project is the latest upgrade to Nepal’s only international airport since it saw its first flight in 1949. The current international and domestic terminals are too small to handle the current annual traffic volume of 8.5 million passengers a year that is growing at 20% a year.

Kathmandu airport to cut flight hours

As Kathmandu becomes more congested and polluted, and with remote online work becoming the norm, many professional Nepalis are planning to retire in Pokhara, or move there.&nbsp; With its stunning mountain panorama, balmy winters and proximity to a profusion of wilderness areas, builders are responding to this demand with new townhouses, housing development and apartments. One such block of flats is the 10-storey <a href="https://sungavaapartment.com/">Sungava Apartment</a> located at Phulbari above the Seti River, near the point where it flows into and under Pokhara. The imposing structure near Manipal Hospital is almost complete, and on a recent visit the site was strewn with huge boulders unearthed while digging the foundation.&nbsp; The Seti brought down these boulders during a gigantic flood that geologists estimate happened 800 years ago when a chunk of Annapurna IV broke off and ploughed into the glacier below. Today, Sungava (means ‘orchid’) sits safely on a high terrace, 100m above the blue-green Seti and commands a view of Dhaulagiri, Annapurna South, Machapuchre, Annapurna III and IV.&nbsp;  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/2024102411104_5f8fc736c86ea3c08d7bef43bb727081d3cc1a2caa55ae2b441717e6044de7e9.jpg" data-media-id="editor_1" data-image-id="2024102411104_5f8fc736c86ea3c08d7bef43bb727081d3cc1a2caa55ae2b441717e6044de7e9" data-rendition-name="original" width="2016" height="1512" loading="lazy" alt="High living below the Himalaya NT"> </figure>  The soil here is conglomerate that has solidified like concrete, and the boulders were extracted by heavy earthmovers. It is intriguing to think that these metamorphic rocks as big as cars, rounded by glacial grinding, were once a part of a much higher Annapurna IV. Even for those with little interest in geology, Sungava is an ideal place to contemplate the tectonic forces that pushed these peaks into the sky to be sculpted into delicate shapes by wind, snow, earthquake and avalanche over millions of years. The view of the Himalayan panorama from Sungava’s many balconies are breathtaking when not obscured by clouds, or the haze that drifts in from across the southern border. On most days, just watching the towering pyramid of Machapuchre (Tamu name: कतासुँ क्लिको) play hide and seek with the clouds is mesmerising. There are rocks aplenty at Phulbari, and it is probably the flowers that grew along the flat terraces e that gave the place its flowery name. The boulders will hopefully be turned into a rock garden while landscaping. An nearby restaurant complex is making the best use of the stones in its design, using flat rocks as outdoor benches and tables. Sungava was designed by the husband-wife architect team of Deepak Sherchan and Jyoti Joshi of <a href="https://thedarkmermaidamarbshrestha.blogspot.com/2013/12/creative-builders-collaborative-cbc.html">Creative Builders Collaborative (CBC)</a>, which also built Heritage Plaza, Indreni Apartment and numerous other projects in Nepal. Sadbhavana retains CBC’s trademark Newari-style masonry and here it borrows from the orange brickwork of the old town of Pokhara, integrating it with modern design elements. A few of those heritage houses are still standing in Ganesh Tole and Ram Krishna Tole in Pokhara’s old quarter.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/2024102411108_5eb64a4885961b6d30781cefeb1e8a313da313ac5227c7a66b60f0c7d48d6fab.jpg" data-media-id="editor_3" data-image-id="2024102411108_5eb64a4885961b6d30781cefeb1e8a313da313ac5227c7a66b60f0c7d48d6fab" data-rendition-name="original" width="1362" height="595" loading="lazy" alt="High living below the Himalaya NT"> </figure>  About 400m from the apartment past a bend on the river, and down below three tiers of terraces in the canyon is a suspension bridge.

There are 52 units at Sungava and it already has a close-knit prospective community of professionals, including doctors, publishers, engineers, and businesspeople from the renewable energy and IT sectors.&nbsp; Some residents say they opted for a second home in Pokhara to make it a ‘base camp’ to explore the Annapurnas with its many hiking trails made newly accessible with new roads. With the NRN citizenship law, overseas Nepalis can now also buy the flats. &nbsp; The floor plans include options for north and south-facing 3-bedroom apartments with verandas, and the facility has underground parking has EV charging, heated pool, sauna and gym. There are still some unsold apartments with panoramic views of the mountains and one can imagine oneself at the kitchen with its huge window, humming a ditty while preparing breakfast: “खाना पकाउँ हिमाल हेरेर...”

When the United Nations held its Summit of the Future at its headquarters in New York in September, many world leaders, including Nepal’s Prime Minister K P Oli, highlighted the effect of climate breakdown in increasing the frequency and intensity of natural disasters. What did not get as much attention was the long term impact of the climate crisis on food production. In fact, heat stress, weather extremes and the consequences on rain-fed agriculture is already being felt worldwide, undermining the chances of the <a href="https://unstats.un.org/sdgs/">UN’s Sustainable Development Goals (SDGs)</a> being met by 2030.&nbsp; The SDG’s 17 targets commit countries like Nepal to reduce poverty and inequality, end malnutrition, protect the natural environment, and ensure that citizens all enjoy health, justice and prosperity without leaving anyone behind.&nbsp; However, besides the impact of climate breakdown on agricultural production, in Nepal the area under cultivation is impacted by urban expansion, falling productivity and the need for expensive inputs like fertiliser and pesticides.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20241019041052_626413c5baf4dae407ac9579231b41daeb51510aa636b75aeb7489d94cca6a62.jpg" data-media-id="editor_1" data-image-id="20241019041052_626413c5baf4dae407ac9579231b41daeb51510aa636b75aeb7489d94cca6a62" data-rendition-name="original" width="999" height="1500" loading="lazy" alt="urban agriculture in Kathmandu"> <figcaption>Kathmandu's urban sprawl is eating into its fertile cultivable lands. Photo: TAYLOR MASON</figcaption> </figure>  Now, a new study led by Nepali researcher Prajal Pradhan at the University of Groningen in The Netherlands looks at how urban agriculture may offer a solution to falling food production and meeting SDG targets. The researchers evaluated 1,450 publications exploring the contributions of urban agriculture with both positive and negative effects, and published their findings in the journal Cells Report Sustainability. Urban agriculture can help achieve 17 SDGs, positively influencing 81 targets. However, it could also undermine 51 goals.&nbsp; Read also: <a href="https://nepalitimes.com/here-now/the-vanishing-land">The vanishing land</a>, Taylor Mason “Urban agriculture offers immense potential for sustainable development, but realising this potential depends crucially on adopting practices that minimise its adverse effects while maximising its benefits,” Pradhan explains. Urban agriculture can substantially enhance urban food security, provide employment to the urban poor, serve as ground water recharge in built-up areas, and preserve open spaces that can serve as safe havens during disasters like earthquakes. However, it also presents problems like the potential health risks from contamination and the need for expensive inputs. &nbsp; “Urban agriculture plays a definitive role in advancing the SDGs, but achieving this requires tailored, context-specific solutions that address the unique challenges of different regions,” says Yuanchao Hu of Wuhan University in China and who is a researcher at the Potsdam Institute for Climate Impact Research. “But it needs equitable access and rigorous management of environmental risks.”&nbsp; Rapid urbanisation is eating into Nepal’s most fertile agricultural land, which means farming in remaining open spaces inside cities can be a viable alternative, especially as food prices rise.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20241019041052_7b7c9413086226fbdc630d45acf772cfa1ced77a8970b9056ec5ec7e5226fdf8.jpg" data-media-id="editor_3" data-image-id="20241019041052_7b7c9413086226fbdc630d45acf772cfa1ced77a8970b9056ec5ec7e5226fdf8" data-rendition-name="original" width="1500" height="999" loading="lazy" alt="urban agriculture in Kathmandu"> <figcaption>A vegetable patch in between new houses in Thimi. Photo: TAYLOR MASON</figcaption> </figure>  “The conversion of Nepal’s most fertile land into cities is a severe problem,” Pradhan told Nepali Times. “Crop cultivation, horticulture, agroforestry, beekeeping, livestock rearing, or aquaculture can all be farming activities within and around cities.”&nbsp; The study makes recommendations for sustainable practices that build on the positive aspects of urban agriculture while mitigating the downsides, thereby promoting more resilient cities in future. Research shows that urban agriculture has been helping many countries attain SDG targets by enhancing food security and biodiversity while helping education and preservation of open spaces.&nbsp; Indeed, many farmers from the hinterland who have settled in Kathmandu Valley or other urban areas of the country have been practicing urban agriculture, leasing neighbourhood patches or cultivating roof gardens both out of necessity because of inflation and falling income to grow their own food, and also as a fulfilling hobby. Saurav Dhakal, a sustainability advocate with Story Cycle and now research fellow at the Asian Institute of Technology in Thailand, says there are socio-economic and environmental benefits of urban agriculture. “It provides benefits to all urban dwellers, regardless of their income status,” says Dhakal, “families get fresh food, and there are many other benefits like water retention, heat regulation and biodiversity. These are all public goods, so special government incentives may be needed.” It is not unusual to see vegetable patches and even paddy fields within inner city Kathmandu where an older generation of farmers are using available fertile land and <a href="https://archive.nepalitimes.com/article/Nepali-Times-Buzz/rooftop-gardens-kathmandu,1415">roof gardens to produce fresh, nutritious food </a>to reduce their dependence on food items that have to be bought after being trucked in from large distances.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/2024101905100_1291ce98dbbb8caed8702ac4b1d469b3e13016d7ecaaf3bfd5f91c974d3c0c77.jpg" data-media-id="editor_5" data-image-id="2024101905100_1291ce98dbbb8caed8702ac4b1d469b3e13016d7ecaaf3bfd5f91c974d3c0c77" data-rendition-name="original" width="1500" height="999" loading="lazy" alt="urban agriculture in Kathmandu"> <figcaption>An older generation of farmers are using any available fertile land to continue farming but it is getting more and more difficult.

There is large outmigration from the mountains to peri-urban areas of the Tarai, to Kathmandu Valley and Pokhara, with many young men then moving abroad for work. Kathmandu Valley’s population has swelled to nearly 3 million, and is growing at 6.5% a year. Dilip Shrestha, 71, used to work for Nepal Food Corporation, so he knew firsthand about inflation, shortages and vegetables with pesticide residue. So, when he designed his new house in Kathmandu, he built a spacious roof where he grows cucumber, ginger, garlic, coriander, onions, tomatoes, chili, beans, okra, pumpkin and lettuce. His family eats healthier, and he has reduced dependence on the market.&nbsp; The co-author of the Cell Reports Sustainability journal article, Daya Raj Subedi who is a PhD candidate at Beijing Forestry University, says urban agriculture also promotes inclusion and psycho-social wellbeing.&nbsp; He says, “A crucial finding of the study is the identification of opportunities and challenges associated with urban agriculture, it can promote sustainable transformation of society.” In Banepa, 55-year-old Bijaya Manandhar in her lifetime has watched the fertile farms of her neighbourhood that used to supply vegetables to Kathmandu, now completely built up with no open space left. The pandemic lockdown prompted her to turn to the family’s <a href="https://nepalitimes.com/banner/rooftop-agriculture-on-the-roof-of-the-world">ancestral livelihood by growing food</a> not on terrace farms, but on the roof terrace.

He adds, “Crop cultivation around cities can be protected by land use plans and regulations. Promoting community-based agriculture, including rooftop gardens, requires community engagement and public-private partnerships across the food value chain.”&nbsp; Such support would accelerate the popularity of existing rooftop farming and community gardens in Kathmandu Valley, or kitchen garden initiatives in Pokhara, and building on traditional farming practices that are preserved and integrated into urban settings like in Bhaktapur and Banepa. In Lalitpur, the Women Entrepreneurship Facilitation Center promotes urban farming enhancing both sustainability and empowerment.&nbsp; Another co-author of the report, Yuanchao Hu from China says followup research of the team will aim to identify good practices in local urban agriculture practices. He adds, “There are examples of urban agriculture that optimise sustainability, ensuring that it remains a viable solution for cities globally while countries try to meet SDG targets.” Prajal Pradhan, Daya Raj Subedi, Kshitij Dahal, Yuanchao Hu, Prakriti Gurung, Sijal Pokharel, Sagar Kafle, Biplav Khatri, Sudeeksha Basyal, Monika Gurung, and Aruna Joshi.

Back to the land in the cities

The 700-year-old Lakshmi Narasingha temple in Bhaktapur houses a rare half-lion and half-human incarnation of Lord Vishnu carrying the Goddess Lakshmi. The temple was destroyed in the 1934 mega earthquake that killed 10,000 people and destroyed many monuments in Kathmandu Valley. It was rebuilt by a German project in the 1980s, but as a single-storey structure instead of its original two-tier pagoda design.&nbsp; With new findings from in-depth research, Bhaktapur municipality began re-restoring the temple in 2021, preserving its original architecture.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20241017131016_2fae38cce543ad7b1f6de632feb3e212e08ed1acedd747830e949d7b8e878f18.jpg" data-media-id="editor_0" data-image-id="20241017131016_2fae38cce543ad7b1f6de632feb3e212e08ed1acedd747830e949d7b8e878f18" data-rendition-name="original" width="2048" height="1365" loading="lazy" alt="In with the old in Nepal NT"> </figure>  “Our temples and heritage sites hold deep meaning. It is disheartening to witness how often they lose their original elements, whether by design or accident,” explains Kumar Chawal of the Consumer Committee of Bhaktapur. “There is a need to preserve our architecture and protect its historical value for future generations. Otherwise, we risk losing a vital part of our identity.” The Laksmi Narsingha restoration is similar to the Bhai Dega temple in Patan Darbar Square which also collapsed in 1934, but was rebuilt with a Moghul-style dome by the Rana government at the time. Only two months before the 2015 earthquake, heritage conservationists had started to rebuild Bhai Dega as the original three-tier based on early photographs. But priorities shifted when four other temples in the square were brought down by the 7.8M earthquake on 25 April 2015.&nbsp;  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20241017131016_697ea707d9ad163be5de5f2efbf5b70d3cab771adcc22f0fae6bf937c6cb0130.jpg" data-media-id="editor_1" data-image-id="20241017131016_697ea707d9ad163be5de5f2efbf5b70d3cab771adcc22f0fae6bf937c6cb0130" data-rendition-name="original" width="2048" height="1365" loading="lazy" alt="In with the old in Nepal NT"> </figure>  This showed how damage to monuments in Kathmandu Valley spanned from one earthquake to the next. Bhai Dega restoration remains half-complete to this day because money for its restoration ran out.&nbsp; Whereas Bhai Dega restoration was done by the Kathmandu Valley Preservation Trust with grants from western embassies and international foundations, in Bhaktapur it is the municipality itself that allocated the Rs30.7 million needed to restore the Lakshmi Narasingha temple. The expected date of completion is early 2025. The municipality and local communities are focusing on two main aspects: preserving the past and promoting localisation. The restoration team has designed a blueprint for the temple by using historical photographs and insights from older generations.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20241017131016_182882fdc393c99e70d1d0490319e415229563666c4934e3a582426ebf00ca30.jpg" data-media-id="editor_2" data-image-id="20241017131016_182882fdc393c99e70d1d0490319e415229563666c4934e3a582426ebf00ca30" data-rendition-name="original" width="1200" height="560" loading="lazy" alt="In with the old in Nepal NT"> </figure>  “At first, the Lakshmi Narasingha temple had only one entrance, but during the demolition process, we uncovered the foundations of four doors. Now, we are restoring all of them. This is an example of how our ancient structures have changed over time, often without our knowledge,” says Chawal. “Constructing temples is not like building houses. They carry historical and spiritual values, which is why they hold a special place in our hearts,” he adds. By replicating ancient design elements and rebuilding the temple as accurately as possible to its original form, the team has stayed true to Bhaktapur’s soul. But the restoration also revived ancient techniques that were in danger of being forgotten, generating employment for woodcarvers, masons, and contractors. The community of Bhaktapur’s Gahiti neighbourhood near the famous Nyatapola Temple has also set aside specific days for locals to volunteer in the reconstruction work. This has encouraged young people to take pride in ownership of their heritage. Families have also supported the effort by donating funds for bells, the temple pinnacle, and other structural features to the temple.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20241017131016_db850ec0c084cdbe54f65bee92dad2ad8122d20fd60ec87ec086fbb9d2f72bd6.jpg" data-media-id="editor_3" data-image-id="20241017131016_db850ec0c084cdbe54f65bee92dad2ad8122d20fd60ec87ec086fbb9d2f72bd6" data-rendition-name="original" width="2048" height="1365" loading="lazy" alt="In with the old in Nepal NT"> </figure>  “I feel at peace knowing I have contributed my sweat to restoring this temple,” said one volunteer. “It is our duty to preserve our temples and heritage. The Nyatapola area will look magical once this temple is completed.” Community mobilisation is a long-standing tradition in Bhaktapur. In the past, locals have actively participated in the restoration of other temples in the city, such as Bhairav and Nyatapola fostering a strong sense of ownership. This collective engagement has not only been crucial in preserving the city's historical monuments but also in strengthening the bond between local communities and their heritage, says officials at the municipality. While securing funding is essential, and the municipality showed it values heritage conservation, the Lakshmi Narasingha restoration is proof that active involvement and sense of responsibility of the local community is as important, if not more. Local involvement also means that the monuments will be cared for into the future, When locals take ownership of these efforts, the restored monuments are not only protected in the present but are also cared for in the future.
