A high-level meeting between the energy secretaries of Nepal and India last month agreed to build six high-voltage cross-border transmission lines to facilitate the export of up to 18,000MW of electricity by 2035. The government’s recently-approved Energy Development Roadmap and Action Plan envisages exporting 15,000MW to India and Bangladesh within the decade, and generating 28,500MW by 2035. At present Nepal has agreements to export 941MW to India and 40MW to Bangladesh. <a href="https://nepalitimes.com/news/blueprint-for-nepal-india-electricity-trade">Exports to India </a>happen only during <a href="https://nepalitimes.com/news/monsoon-deluge-in-nepal">the monsoon </a>when there is <a href="https://nepalitimes.com/here-now/an-energy-windfall-for-nepal">surplus energy</a>, and <a href="https://nepalitimes.com/from-the-nepali-press/more-than-half-of-nepal-s-electricity-imported-from-india">Nepal imports power</a> during the dry season. This month, Nepal is generating only one-third of its installed capacity of 3,400MW because of low river flows.&nbsp; Generation will exceed 4,000MW by year-end, and another 3,906MW of projects are under construction with more projects worth 3,899MW in the pipeline after <a href="https://archive.nepalitimes.com/news.php?id=10871">power purchase agreements</a>.&nbsp; That Nepal is now capable of generating and exporting <a href="https://nepalitimes.com/here-now/nepal-s-precious-electricity-going-waste">surplus electricity</a> has been seen as a significant development for a country that was <a href="https://nepalitimes.com/here-now/how-they-kept-nepal-in-the-dark-ages">plagued by power cuts</a> for up to 18 hours daily until just eight years ago.&nbsp; In the past 20 years, many energy strategies were formed to power growth through exports. As regional countries look for <a href="https://nepalitimes.com/here-now/right-climate-for-nepal-s-energy-transition">clean energy to meet climate targets</a>, <a href="https://nepalitimes.com/here-now/nepal-s-first-hydropower-from-a-glacial-lake">Nepal’s hydropower</a> could be in high demand. Electricity exports can also help offset the country’s huge <a href="https://nepalitimes.com/news/balance-of-power">trade deficit</a> with India. <a href="https://nepalitimes.com/news/balance-of-power">Investment</a>, or the lack of it, stands as the biggest hurdle in achieving Nepal’s ambitious energy export targets. Generating 28,500MW of electricity would cost Nepal $46.5 billion — four times the annual budget. Capital investment could come from <a href="https://nepalitimes.com/editorial/home-is-where-the-heart-is-yqkvf5vx">overseas Nepalis</a>, <a href="https://nepalitimes.com/news/sacking-of-nea-chief-exposes-cronyism">the Nepal Electricity Authority (NEA)</a>, the private sector or from<a href="https://nepalitimes.com/business/green-bond-option-for-climate-finance"> ‘green bonds’</a>. But even if investment is forthcoming, there is no guarantee that the energy will find a market at an acceptable price. India has increased its quota every year to allow the NEA to sell 941MW of electricity produced by 28 projects under the competitive market and medium-term power sales agreements. It does not buy power from projects with Chinese involvement, and has a strategic monopsony status.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/2025032710034_ac849c5d570b132afcdb2e4ba432a423dc40bb80ad9f900e0d1a26eed1a5dbec.jpg" data-media-id="editor_14" data-image-id="2025032710034_ac849c5d570b132afcdb2e4ba432a423dc40bb80ad9f900e0d1a26eed1a5dbec" data-rendition-name="original" width="997" height="784" loading="lazy" alt="Hydrocarbon to hydropower NT"> </figure>  The country exported more electricity than it imported for the first time in 2023/24 fiscal year, selling electricity worth Rs17.06 billion to India. But this is a drop in the bucket in comparison to the country’s total trade deficit. Nepal imported goods worth Rs1.59 trillion, while exports were only Rs152 billion in the same fiscal year. The amount earned from exporting electricity was just 1.2% of Nepal’s trade deficit. While this could increase in future, it will not go up by much. As it stands, Nepal buys electricity from India at almost the same rate as it sells. Indian state-owned companies are <a href="https://nepalitimes.com/opinion/decentralising-hydro-power">developing hydropower projects</a> with a combined capacity of 8,000MW, mostly on the Arun basin. The agreements give 21.9% of the electricity from these plants for free for 25 years before they revert to Nepal. Hydropower experts have long argued that Nepal should increase domestic consumption for value added manufacturing rather than exporting raw power. This means <a href="https://nepalitimes.com/opinion/comment/securing-nepal-s-electric-future?%3D">making electricity affordable and accessible</a> for household appliances, transport and industries. To be sure, proactive government policies on tax rebates for electric vehicles have seen remarkable results. Until January of this fiscal year, Nepal imported 6,256 electric four-wheeled vehicles in comparison to 2,662 petroleum ones. Nearly 70% of all EVs sold were from China.

Hydrocarbon to hydropower

This is the first instalment in a new limited series in Nepali Times on the historic transportation infrastructures of Nepal. Nepal’s Forest Railways As<a href="https://nepalitimes.com/here-now/india-s-border-trains-that-connected-nepal"> India’s railway network </a>expanded in the 1890s and 1900s, the demand for wooden railway sleepers, called ‘ties’ in America, likewise increased. The <a href="https://archive.nepalitimes.com/article/Nepali-Times-Buzz/the-rana-reign-a-recap-of-history,3751">Rana regime</a> realised that western Nepal’s dense forests, from which sal trees could be extracted and sold, represented a valuable source of revenue. There was a problem of accessing large tracts of <a href="https://nepalitimes.com/here-now/the-tarai-s-shrinking-forests">Tarai forests</a>. However, once Indian railway lines are extended to Nepal’s border in several places, this issue could be resolved by constructing logging railways, also known as ‘tramways’ or ‘light railways’. The Nepal Government awarded a contract to Punjabi timber contractors to supply 15,000 sal sleepers to Chandan Chauki station of India’s Oudh &amp; Rohilkhand State Railway in 1908. The contractors also received a concession to construct a steam tramway to run 48km into <a href="https://nepalitimes.com/banner/reviving-nepals-community-forestry-success-story">Nepal’s forests</a> for cutting and transporting trees. The author found no records, however, indicating that such an ambitious tramway was built in 1908. The hewn logs were probably carried into India by bullock carts or <a href="https://nepalitimes.com/news/elephants-become-white-elephants">elephants</a>. The earliest known forest railway in Nepal was built in 1914 in the southwestern corner of the present-day Parsa district. A British engineer went to the Indian border town of Bikna Thori to plan a 4-mile portable light railway for the transport of timber from <a href="https://nepalitimes.com/here-now/on-the-tri-junction-of-wildlife-conservation-conflict-and-co-existence">the forest of Chitwan </a>to the Thori depot on the Bengal &amp; Northwestern Railway. This short line was laid upon wooden sleepers, and its rails could be taken up and repositioned when logging in one section of the forest was completed. This forest railway was in operation at least through 1917.&nbsp; A few year down the line in 1923, J V Collier of the Indian Forest Service built a narrow-gauge railway in Kailali district also to export of timber to India. This line, the Nepal Government Forest Railway, departed Chandan Chauki in Uttar Pradesh and ran 48km northwest into Nepal.&nbsp;  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20250824150820_84ddef57433c2f847b2c7e56c2d9c924084b6e6a504bbca905d2c593fac8eabd.jpg" data-media-id="editor_6" data-image-id="20250824150820_84ddef57433c2f847b2c7e56c2d9c924084b6e6a504bbca905d2c593fac8eabd" data-rendition-name="original" width="1130" height="689" loading="lazy" alt="Nepal's little railways"> <figcaption>A Nepal Government Forest train in Kailali District hauling sal sleepers in 1925. Photo: DAVID CHURCHILL </figcaption> </figure>  It was a 2-foot railway supported by 11kg rails. The line was ‘temporary’ in that as sal trees were thinned out in one area, railway tracks were shifted to uncut areas of the forest. The railway crossed seven small <a href="https://nepalitimes.com/here-now/saving-what-is-left-of-himalayan-rivers">rivers</a>, but the bridges were taken down during the summer and monsoon. Trains ran only from November to April. This forest railway purchased four 4-6-0T ‘tank’ engines built in Leeds, England. Each bogie could carry 100 broad-gauge sleepers, and two engines were needed to haul a 21-car train loaded with 2,100 sleepers. This huge commercial forest operation once employed about 14,000 men, most of them Indians. During one season, nearly 800,000 broad and metre-gauge sleepers were exported to India. When India suffered a depression in 1930, large scale operations came to an end.

It ran from Nishangada in India to Khairbhatti in Nepal. From there, stations heading south were Ranipur, Karmak, Taratal and Madhuwan. Collier likely <a href="https://nepalitimes.com/here-now/nepal-train-project-struggles-to-stay-on-track">built this railway </a>as well in the 1920s. An elderly man in Bardia in 2022, whose father had worked on this forest railway, was interviewed for this account. Kathmandu Valley’s Motor (Trolley) Railway Merchants importing goods from India via the<a href="https://archive.nepalitimes.com/article/business/ropeways-connecting-nepal,1749"> ropeway</a> Chandra Shamsher built in 1927 had to go to the ropeway’s terminus at Matatirtha near Thankot to claim their goods and then haul them 6km to the customs house Bhansar Adda at Teku for clearance and payment of customs duties. The Motor Railway was built to carry goods from the<a href="https://archive.nepalitimes.com/news.php?id=16839"> ropeway station </a>directly to the customs office, making it cheaper and more convenient for merchants to receive their shipments. In December 1931, Prime Minister Bhim Shamsher issued an order (sanad) putting Lt Gen Singha Shamsher Rana in charge of building this rail line to Teku and on to ‘Nabalak Khana’ in Tripureswar, a distance of 10km. The project was subdivided into four sections or ‘phant’, and for each, budgets and timelines were established. There was bato phant (constructing the roadbed), lik sleeper and jordne phant (laying sleepers and joining the rails), culvert phant (installing culverts) and pul phant (building bridges). Colonel Kishore Narsingh Rana was put in charge of the sleeper and rail section, while Colonel Dilli Jung Thapa, an engineer at Ghar Kaj Adda, also was involved. The Motor Railway was completed by the end of 1933. In the beginning, the railway’s small wagons may have been pulled and pushed by men and bullocks. However, in 1938 a British railway manufacturer sent Nepal a four-wheel, 5½ ton, 2-foot narrow-gauge diesel-powered locomotive with mechanical transmission, hence the name motor railway.

The charge for transporting one maund (about 40kg) of cargo from Matatirtha to Teku was 50 paisa. Even though the trains ran slowly and only for a short distance, <a href="https://nepalitimes.com/news/fatalism-and-fatalities">accidents were not unknown</a>. A train loaded with rice, salt and cotton derailed on a curve in July 1946, and two railway employees were crushed under the cars and killed, five others were injured.

Floods in 1950 inundated 500 villages in Bihar and left 500,000 people homeless. The two governments signed an agreement in 1954 to build a barrage on the Kosi, and King Mahendra and Prime Minister Nehru laid the foundation stone in April 1959. To transport stones from a quarry near Dharan to use in mixing concrete at the construction site, the Indian government, in charge of building the barrage, made plans to build a narrow-gauge railway linking Bihar and its border town of Bhimnagar with Nepal’s settlements at Chakraghatti, Chatra and Ghopa, the outskirts of Dharan.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20250824150816_fc5e13b01022c63c64f1e83589da0015eee7ecd002bdd3d97b88c98c1f3d45b7.jpg" data-media-id="editor_21" data-image-id="20250824150816_fc5e13b01022c63c64f1e83589da0015eee7ecd002bdd3d97b88c98c1f3d45b7" data-rendition-name="original" width="4011" height="2645" loading="lazy" alt="Nepal's railways"> <figcaption>Steel plaque commemorating the construction of a Motor Trolley bridge across the Balkhu Khola.

The stations south of Chakraghatti were Rajabas, Maduhuwan, Kushaha, Haripur and Bhantabari. The line built, operated and owned by the Indian Government, was opened in 1958 and known locally as Dhunge (stone) Rail. Procuring locomotives, wagons and other materials was a challenge. India’s Railway Board searched the country for old 41 lb rails, and located steam engines, most built around 1910, in poor condition, and stored in ‘retirement’. These decrepit locomotives were later cannibalised for parts to keep the remaining engines running, and six newer locomotives built in Yugoslavia were sent to the KPR in 1960 to prevent the railway from shutting down and halting construction of the barrage.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20250824150832_fd644f9e2674c5047a531de5dfeb2c8860b0f93dddc7a2df3db867bf31b2c94b.bmp" data-media-id="editor_22" data-image-id="20250824150832_fd644f9e2674c5047a531de5dfeb2c8860b0f93dddc7a2df3db867bf31b2c94b" data-rendition-name="original" width="3171" height="2069" loading="lazy" alt="Nepal's railways"> <figcaption>KPR locomotives, water tank and staff at Chakraghatti in Nepal.

A hundred new wagons arrived from Japan, but only half could be put in service, as couplers from the other 50 were removed and attached to the Muzaffarpur wagons. This smorgasbord of equipment kept shop mechanics and work crews busy, but now-abandoned railways in Nepal always operated under less-than-ideal conditions. Although the purpose of the KPR was to transport gravel, stones and boulders to the site of the barrage, photographs show people riding in loaded wagons. Excluding Dharan, there was no bus service through the wild animal infested jungle between Dharan and Chakraghatti or along the dusty paths linking other small villages on the KPR, so patient locals sat in wagons at Dharan, waiting perhaps for hours for trains to depart.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20250825020852_7d011dcc8e9b8cb0fe745b352486ebc4a84dac99419eadb35875333db20837c6.jpg" data-media-id="editor_24" data-image-id="20250825020852_7d011dcc8e9b8cb0fe745b352486ebc4a84dac99419eadb35875333db20837c6" data-rendition-name="original" width="3965" height="2659" loading="lazy" alt="railways in Nepal"> <figcaption>Ticketless riders on a train of gravel and stones in the forest between Dharan and Chakragatti in 1966.

Southbound trains carried gravel, stones and boulders, while northbound trains would carry coal, cement and provisions, including sacks of coins to pay the workers. Trains even ran at night, and the crews worked long hours. Workers received free housing in project-built tenements but had to buy food supplies and items for personal use. The Babu Saheb or the superintendent lived at Chakraghatti, and at one time supervised more than 1,000 employees, nearly all of them from India. The barrage was completed in 1964, but by 1970, the Kosi Project Railway had passed into history. Daniel W Edwards was a Peace Corps volunteer in 1966 and is the author of several books on Nepal.

Nepal’s five little railways

· &nbsp;At least 400 people are dead or missing after heavy rainfall lashed arid regions of northwestern Pakistan. Walls of mud and boulders engulfed entire villages in Khyber Pakhtunkhwa Province. More than 700 people have been killed in floods in Pakistan since June.&nbsp; · &nbsp;Over in India’s Jammu and Kashmir at the same time, multiple slurry floods on 17-18 August killed more than 80 people · A mudslide possibly caused by a glacial collapse upstream in Uttarakhand on 5 August nearly wiped the village of Dharali off the map. At least 70 people, 23 of them Nepalis are dead or missing. · On the night of 8 July, <a href="https://nepalitimes.com/news/rasuwa-flood-likely-a-glof">glacial lakes in Tibet overflowed</a>. By dawn the mudflow had demolished the Nepal-China border bridge killing at least 11 people, destroyed hydropower plants, swept away bridges, roads, over 100 cargo trucks and newly imported electric vehicles. All these disasters have a common thread: a cascade of hazards caused by record-breaking rainfall on fragile Himalayan slopes destabilised by melting glaciers and permafrost, seismicity and poorly engineered infrastructure. They are called ‘rain bombs’ — a heavy localised downpour measuring more than 100mm/h on a steep mountainside. As global warming heats the atmosphere, warmer air can hold more water vapour. The heavy rain then falls where there should be snowfall: on moraines and slopes that have lost the permafrost adhesive that held the debris together. “Increasingly, there is now more rainfall at higher altitudes where there used to be snowfall previously, and this directly impacts loose material in that fragile landscape which moves down,” explains Mohan B Chand, a Himalayan Glaciologist at Kathmandu University. “Moreover, the rains these days are heavy and fall within a few hours. So even a small burst has bigger impact.” The <a href="https://nepalitimes.com/banner/drones-to-the-rescue-in-melamchi">2021 Melamchi flood</a> and the <a href="https://nepalitimes.com/news/sikkim-flood-is-warning-to-nepal">Sikkim disaster in 2023</a> have been attributed to record-breaking torrential rain on a glacial moraine that collapsed, unleashing a catastrophic debris flow.&nbsp; The Bhote Kosi flood this year happened even without torrential rain, and originated at rapidly expanding supraglacial lakes that overflowed, similar to what happened on the Mendenhall Galcier in Alaska last week. In Uttarakhand, the trigger could be in the upper catchment cryosphere, or a landslide dammed lake. Basanta Raj Adhikari of the Centre for Disaster Studies at the Institute of Engineering also calls them ‘sediment bombs’. He clarifies: “There is lots of sediment up there from landslides or glacial activity, and when there is heavy rainfall and hotter temperature, they are unleashed downstream. One thing is for sure, these extreme events are getting more frequent and more destructive.” Researcher Alton C Byers who has studied melting glaciers in the Himalaya and Andes names the eight most potentially dangerous glacial lakes in Nepal: Lower Barun, Chamlang North Tso, Chamlang South Tso, Dig Tso which burst in 1984, Lumding Tso, Thulagi, Tso Rolpa and Imja Tso (see map).  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20250822030844_70b3bf6a1ad9b9f9481c9af860629b2a05ac1338a3b89a831506f1c6bdddf5ec.jpg" data-media-id="editor_3" data-image-id="20250822030844_70b3bf6a1ad9b9f9481c9af860629b2a05ac1338a3b89a831506f1c6bdddf5ec" data-rendition-name="original" width="522" height="557" loading="lazy" alt="high risk glacial lakes in Nepal"> </figure>  Of these, Tso Rolpa and Imja have been lowered by 3m each, while Thulagi, Lower Barun, Lumding Tsho, and Hongu 2 glacial lakes have been targeted for lowering by the Department of Hydrology and Meteorology as part of the recent Green Climate Fund grant of <a href="https://nepalitimes.com/here-now/meltpools-in-the-himalaya" target="_blank">$36.1 million awarded to Nepal</a>. “These lakes have changed over the years as their debris-covered glaciers continue to recede,” Byers told Nepali Times. “When water volume in the lake basin increases, they become more vulnerable to flood triggers such as overhanging ice as glaciers recede further to their headwalls, and permafrost on their moraines continues to melt.” <h2>These are not ‘natural disasters’</h2> Scientists have given the current planetary epoch a name: the Anthropocene. And anthropogenic causes in this era heighten the risk of disasters. Indeed, an analysis of recent Himalayan calamities (page 1) shows that there is much more at play here than climate breakdown. Haphazard encroachment of floodplains, quarrying and crusher activity exacerbated the effect of <a href="https://nepalitimes.com/editorial/when-it-rains-it-pours-ksqprbu3">extreme rainfall on 28 September around Kathmandu Valley</a> that killed 200 people. The human cost of the 5 August catastrophe in Uttarakhand would have been high in any case, but the fact that the tiny village had expanded across a vulnerable alluvial fan to cater to a tourism boom meant more death and destruction. There are similar alluvial fans across Nepal, where small towns have expanded because new highways follow rivers, like Beni located at the confluence of the Myagdi Khola and Kali Gandaki. Other towns like Kagbeni or Damauli are located on the banks of rivers and tributaries that are directly downstream from rapidly expanding glacial lakes or unstable mountains. “In Butwal, people are building houses on the floodplain of the Tinau River, and yet people blame climate change or rainfall when there is a disaster,” says Basanta Raj Adhikari at the Institute of Engineering. “This is happening all over the country. Imagine the kind of devastation Beni would suffer if there was a big flood.”  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20250822030848_ed411f8618c7a411ed4c165e91f3b880abb085a8a511405710dd8220f657da84.jpg" data-media-id="editor_6" data-image-id="20250822030848_ed411f8618c7a411ed4c165e91f3b880abb085a8a511405710dd8220f657da84" data-rendition-name="original" width="1200" height="800" loading="lazy" alt="Beni Bazar"> <figcaption>RISKY CONFLUENCE: Beni has expanded rapidly after the highway to Mustang was built. But the town is situated on the alluvial fan of past flash floods on both the Kali Gandaki and Myagdi Khola which have dangerous glacial lakes in their upper catchment. Photo: BENI TOURISM</figcaption> </figure>  Traditionally, Nepal’s villages and settlements were located high above rivers because our forebears learnt lessons from recurring flash floods. Now, the road network follows rivers, and towns have sprung up along these highways. Even when roads are not on river banks, many gouge out slopes above, unleashing massive landslides that block rivers. Experts say Nepal’s hazard map should now be updated for glacial outbursts so municipalities can plan risk-sensitive land use zoning. This &nbsp;must go hand-in-hand with measures to reduce the risk by structural mitigation, such as engineering and construction, and then with risk awareness and early-warning systems. Says Himalayan researcher Alton C Byers: “Sooner or later, communities will realise that certain sites are simply no longer safe for a village or city, especially because of climate change in the mountains. The Himalaya has always been high-risk with its steep slopes, thin soil, monsoon rainfall regime, and frequent seismic activity. So, some places are no longer safe to live in.” Mohan B Chand of Kathmandu University adds that <a href="https://nepalitimes.com/banner/climate-smarter-himalayan-infrastructure">hazard mapping is especially crucial for expensive hydropower plants</a>: “Most of these are on snow-fed rivers, but environmental risk assessment is not taken seriously.” He says that because Nepal is set to generate 28,500MW by 2035 to meet its carbon neutral target, the government must work to minimise upstream risk by integrating disaster mitigation components in new energy investments. Few know that Nepal’s first hazard mapping was done 40 years ago in the Khumbu with a United Nations University study titled ‘Highland Lowland Interactive Systems’. It is hard to find that document anywhere. Today, hazard mapping technologies, satellite remote sensing, drones, synthetic aperture radar (SAR) and modelling with AI have made it much easier to integrate multi-hazard risk assessment. That data needs to be made available to local governments so they can plan. Cell phones and new apps that monitor real-time glacial lake levels, live precipitation and hydrological data, and local weather forecasts can make early warning systems more effective. Recent disasters have shown that even the smallest of glacial lakes that are rarely considered in risk assessments can cause much damage. Langmale Lake in the Barun Valley was less than 0.1 km2 in size, but <a href="https://nepalitimes.com/here-now/nepal-s-mountains-are-melting" target="_blank">the flood in 2017</a> caused extensive downstream damage. The 2012 Seti flood in Pokhara, the Chamoli disaster in Uttarakhand in 2021, the South Lhonak proglacial lake burst in Sikkim in 2023 that washed away the $1.7 billion Chungthang Teesta III Project, and the August 2024 floods above Thame in Khumbu are other recent examples.&nbsp; Byers thinks some of these floods may have been initially triggered by massive rockfall or moraine collapse related to <a href="https://nepalitimes.com/multimedia/the-not-so-permanent-frost" target="_blank">melting permafrost</a>. The size of a glacial lake alone does not determine the severity of destruction. What makes all the difference is downstream development, and if there pre-warning. Dig Tso in Khumbu which burst in 1984, was much larger than the lake that caused the Bhote Kosi flood in July, but the economic cost to the country of the trans-boundary disaster this year was much higher. Says glaciologist Chand: “We have to monitor the lakes, not just via remote sensing but with field visits. These may be costly, but mitigating the risk is less expensive than the disasters themselves.” Nepal has the technology and trained personnel to do hazard mapping, monitoring, and to design early warning apps. That data and information now needs to be available to all three levels of government to improve preparedness and risk reduction. “The cascading and compounding hazards are increasing in the Himalaya, this must be the subject of our research now,” says Adhikari at the Centre for Disaster Studies. “Recent events are a wake-up call, if we do not take this seriously things may be more dangerous in future.”
