Men of Stone: A Reflection on Richard Simon’s Thomia

Published

on

S. Thomas’ College

Richard Simon’s monumental two volume history of S. Thomas’ College runs into 869 quarto-sized pages, inclusive of endnotes but excluding front matter and indices of subjects and persons. The book is extremely well written, in a very erudite but engaging style, and unique in that the history of the school (founded in 1851) is interspersed with that of Lanka (i.e. its political, economic, ecclesiastical and educational landscape), covering the 200 years, from 1801 to 2001. In fact, the book is subtitled, “The entangled histories of Lanka and her greatest public school”. I cannot, in this article, hope to be truly representative of Simon’s magnum opus, but will focus on aspects and themes that struck me. Apart from being purely illuminating and both sobering and inspirational, history can also serve as a critique of the present, and I make some attempts at this, too.

One of the chapters in Volume I is titled “Men of Stone”

– referring, of course, to Thomians fashioned by Warden William Stone. But all Thomians, as well as S. Thomas’ College itself, are also often described by the term ‘grit’ (the title of a chapter in Volume II) – literally small pieces of stone, but used metaphorically to characterise the trait of perseverance. SWRD Bandaranaike himself is portrayed as displaying this attribute through his calm demeanour on his deathbed after being fatally shot down while in office as Prime Minister. The chapter on Stone is titled “The Cornerstone”, reflecting his central role in the school, not only in shaping its values, but also in overseeing its transition from Mutwal to Mt. Lavinia. I recall my grandfather saying that the early Thomians were called “Gal Palliye’ Kollo” (boys from the stone church), a reference to their grit through an analogical link to the then Anglican cathedral on their Mutwal premises, described by Bishop James Chapman (both the founder of the school and first Anglican bishop of Colombo) in his memoirs as having its foundations and columns constructed of stone. As you may have guessed, the above serves to justify the title of this article.

Simon identifies four key wardens of the school while giving them appropriate chapter titles – Rev. Edward Miller, “The Paragon” (1878-1891); Rev. William Buck, “One of the Boys” (1896-1901); Rev. William Stone, “The Cornerstone” (1901-1924); and Rev. Reginald De Saram, “The Defender” (1932-1958) – after all of whom four of the school’s houses are named today. As you may gather, the titles of Simon’s chapters are as intriguing as their contents. The author speaks highly also of Neville de Alwis (1983-1998), who is credited with a restoration of the college after somewhat of a decline.

The continuity of both funds and heads was a serious problem that S. Thomas’ had in its early years, with Bishop Chapman having to intervene from time to time. Edward Miller’s tenure is the one that put the school on a firm footing after such vicissitudes, which included the collapse of the coffee plantations. The patience, humility and fortitude of the Paragon would have been a key factor in such stabilisation. We should marvel at the commitment of these early pioneers of modern education in Sri Lanka, and, indeed, try to emulate their willingness to leave the comforts of the familiar for service in the uncomfortable.

Although the youthful William Buck was warden for only six years, he is probably immortalised for his statement on the tension between a public school’s intra and extra mural activities: “A public school does not exist only, or chiefly, for the culture of the mind – there is a nobler culture even than this, the culture of character. The first and primary object of a school is to turn out men, and so long as there is an advance in the manliness and honour of our boys, I care but little what happens in other respects”. This tension exists to date, with Buck’s sentiments preserved in the school – the trick, however, is to ensure that there is, in fact, a tension, rather than ‘one-way traffic’ (to change the metaphor) in one direction or other. It is also interesting that the Buck House motto is “Mens sana in corpore sano” – “A healthy mind in a healthy body”.

We now come to William Stone, whose chapter title could even have been “The Enigma” (which title Simon allocates to a separate short-lived warden). For one thing, Stone came from a working class background, and would have completed a Cambridge education probably only because of a conjectured benefactor. Simon wonders whether this is why Stone preferred Ceylonese company to that of his compatriots on his sojourn in this land. This warden was, however, one of the most erudite the school has had, being a Greek scholar of considerable repute and serving as a Classics lecturer at the University College in Colombo, after his wardenship at S. Thomas’. This did not prevent him, while being warden, to introduce a ‘Commercial’ stream of study, to promote a very practical education that was readily supported by the Ceylon Chamber of Commerce. Stone was thus attuned to the realities of the future in his time. He also ensured, after the relocation to Mt. Lavinia, that the limited funds available were used first for constructing science labs, while the chapel had to wait its turn. His churchmanship, too, was of the non-ritualistic ‘low church’ form, and somewhat at variance with the ‘high church’ tradition that has dominated the college chapel. So, although William Stone may have been the greatest warden the school has had (“The Cornerstone”, according to Simon), he certainly did not easily fit the mainstream of sentiment that the school represented; and there is surely a lesson in that.

By the time Reginald De Saram became warden, the school needed a “Defender” – i.e. against populist Lankan sentiment that the British public school type elitist education offered at institutions like S. Thomas’ had outlived its time, if not actually prevented the flowering of a more ‘grassroots’ educational system in the country. A lot of Volume II (1948-2001) is devoted to this fascinating tension, which was heightened by nationalistic feelings engendered by Ceylon’s independence from British rule. De Saram is portrayed as fulfilling his ‘defender’ role admirably, in some cases even ‘going on the offensive’ (to remain with the metaphor) and stealing a march over other nationalists, especially through his fostering of an enviable array of Sinhala teachers, whose “Hela havula” movement (one seeking to promote indigenous purity in the Sinhala language) found a home at the college. The son of one of those teachers is today a Professor of Sinhala at the University of Colombo, after having studied at S. Thomas’ himself and later obtaining a doctorate from Cambridge University.

In fact, although S. Thomas’ is often identified with an ethos of westernised education, Simon’s history makes it clear that, apart from the Hela havula teachers, there were many subsequent nationalists of various hue who passed through its portals as students, including SWRD Bandaranaike, Anagarika Dharmapala, Ediriweera Sarachchandra and Devar Surya Sena, who is mentioned here because he provided the musical setting for the Sinhala Anglican liturgy. The book also describes how Thomians were victorious in the All-Island Inter-School Sinhala Debating Championships in 1978 – almost 50 years ago, to be sure, but just 30 years after Independence and on the 50th anniversary of the Sinhala Literary and Debating Society. So, today, on the 175th anniversary of the college, there are various competitions being held on English essay writing and oratory, open to students all over the country. That is a good way to celebrate Thomian contributions to English language competence over the years. But maybe the school should follow this up with corresponding competitions in Sinhala, as well, because she has clearly played a part in the fostering of that language, too. Arisen Ahubudu, one of the Hela havula teachers, is a household name in Sri Lanka.

The school’s contributions to Tamil are not so evident, maybe because institutions in Jaffna had a monopoly on that. But it did produce SJV Chelvanayakam, who is referred to in the book as having been a master at Mutwal under Warden Stone (in Volume I). He would have been a contemporary of SWRD Bandaranaike, both in school and politics, and their “Banda-Chelva” pact in 1957 is reported on in Volume II. Perhaps, S. Thomas’ should take greater cognizance and ‘ownership’ of “Chelva”, as they do of “Banda”; because while the latter is either consigned to the pages of history or blamed for all our current ills in some quarters of the South, the former is still treated with respect and affection in the North as “Thanthai (Father) Chelva”. Maybe that could have been another chapter title for Simon to write on. It is rumoured that Banda and Chelva were members of the same college debating team as well; and perhaps S. Thomas’ could think of adding Chelvanayakam’s name to its English inter-school debating competition, named after Bandaranaike.

Schools, such as S. Thomas’ that were established in 19th century colonial Ceylon, were western in orientation because their principals or headmasters (‘wardens’ at S. Thomas’) came from the west. In fact, it was an unwritten rule that such wardens be graduates of Oxford or Cambridge Universities (and also ordained Anglican ministers). Although this was not always possible after the middle of the 20th century, many of the wardens had overseas exposure. It is this exposure that bestowed upon these schools a link to the outside world and a global perspective.

There were others masters from overseas who helped in this process as well. Special mention is made of W.T. Keble, a historian who was also the first Headmaster of the Kollupitiya branch school, and R.L. Hayman, a scientist (and more pertinently an ‘outdoorsman’) who was a Headmaster at the Gurutalawa branch school. At Mt. Lavinia, however, they joined forces in fostering The Literary, Scientific and Historical Society – “an exclusive club for the brainiest boys, membership being by invitation only, which met every Friday evening to listen to lectures and discussions on assorted highbrow subjects” (e.g. readings from Chaucer, recordings of Elizabethan madrigals, lectures on ‘Heavy Hydrogen,’ etc.,). The school has been trying, for some time now, to broaden the horizons of A/Level students through a Current Affairs class, but the above exclusivity in the domain of the mind (similar to that in a competitive sports team) may be something that will spur the best students to subsequent heights of intellectual achievement. And this was possible in the day because of teachers with such expertise and global exposure. Once again, schools like S. Thomas’ appear to be seeking overseas expertise today in sports (e.g. rugby) coaches, but not so much for cultivating the mind. Rev. Roy Bowyer-Yin emulated Keble and Hayman in the field of music, and was responsible for transporting the much-loved festival of nine lessons and carols from Cambridge to Mt. Lavinia. He also helped a few boys to further their musical exploits globally.

Schools that have long histories develop strong traditions. Tradition will of course be tested against current relevance, but will also serve to critique the superficial interests of immediacy. S. Thomas’ had two institutions that are specifically mentioned in its Board of Governors Ordinance, namely the Divinity School and the Orphanage. The former has been relocated to the Cathedral Premises and the latter closed down in 1940. I am not calling for a re-establishment of these institutions in the school. But their presence in the premises must have surely shaped the character of the school and its boys. So, perhaps today’s school can consider the setting up of contemporary structures for serving the poor, presumably in nearby communities, and exposing the boys to the process too; and also for religious education. One possibility for religious education (in its broadest sense) is a model similar to that adopted by King’s College London for their Associateship of King’s College (AKC), conducted in parallel with all its other programs and open to all students and staff, which is described in its website as being “at the heart of the College’s commitment to an international, interdisciplinary, and innovative curriculum … [and] seeks to foster an understanding of different beliefs and cultures that can be taken into wider society”.

Iain Douglas-Hamilton: Science, courage, and the battle for elephants

Published

on

Iain Douglas-Hamilton

Passing of Iain Douglas-Hamilton, a man who dedicated his life to conservation and whose life’s work leaves a lasting impact on our appreciation for, and understanding of, elephants.

– Prince William

In Africa on 08 December, 2025, when the sun slipped below the horizon, it did not only give an end for that day, but it also marked the end of a man whose knowledge and courage saved Africa’s elephants. This gentleman was none other than Iain Douglas-Hamilton! There is a beautiful African proverb that says, “When an old man dies, a library burns to the ground,” and it resonates well with Iain’s demise.

Iain pioneered behaviour research on elephants, and he was the first to highlight the elephant poaching crisis in Africa. Also, the adventures he went through to save the elephants will inspire generations.

From Oxford to Africa

The Life of the Last Proboscideans: Elephants”, authored by Muthukumarana, stands as an awardwinning, comprehensive study that integrates elephant evolution, anthropology, biology, behaviour, and conservation science.

Iain was born on 16 August, 1942, into an aristocratic family, the son of Lord David Douglas-Hamilton and Ann Prunella Stack. His parents were a distinguished couple in Britain: his father, a Scottish nobleman, served as a squadron leader in the Royal Air Force, while his mother was a pioneering figure in physical fitness and a prominent advocate for women’s rights. After finishing his school, Iain was admitted to Oxford University to study zoology. At the age of 23, for his PhD, Iain travelled to Tanzania to study the behaviour of elephants at Lake Manyara National Park. This was a daring and humble beginning that would change how the world understood elephants. He learnt to recognise individual animals based on their tusks and ears. He observed their family bonds, their grief, and their intelligence. These findings made the scientific community identify elephants as sentimental beings. During this period, he married Oria Rocco, and together they had two children, Saba and Mara.

Battle for the elephants

When ivory poaching swept across Africa and devastated elephant populations, Iain did not withdraw in despair. He confronted the crisis head-on, guided by science, rigorous data, and unwavering resolve. Through extensive aerial counts and field studies, he laid bare the scale of the tragedy—revealing that Africa’s elephant numbers had collapsed from an estimated 1.3 million to just about 600,000 in little more than 10 years.

It was largely thanks to his work that the global community saw—perhaps for the first time—the full scope of the crisis. His efforts played a pivotal role in pushing forward the 1989 international ban on ivory trade, a landmark moment for wildlife conservation.

In 1993, Iain founded Save the Elephants (STE), an organisation that would become the heart of elephant conservation efforts in Kenya and across Africa.

At STE, he pioneered the use of GPS-tracking and aerial survey techniques to monitor elephant movements, protect them from poaching, and plan safe corridors for them in increasingly human-dominated landscapes. These methods have since become standard tools in wildlife conservation worldwide.

Beyond technology and science, Iain was a mentor. He inspired — and continues to inspire — generations of conservationists, researchers, and everyday people who care deeply about wildlife. Through his books (such as Among the Elephants and Battle for the Elephants), documentaries, lectures, and personal example, he invited the world to see elephants not as trophies or commodities, but as sentient beings — worthy of awe, study, and protection.

Iain and Sri Lanka

In 2003 Iain came to Sri Lanka for the first time to attend the “Symposium on Human-Elephant Relationships and Conflict” as the keynote speaker. On that day he concluded his address by saying, “When I hear the talk of Problem Animal Control, I always wonder whether our species has the capacity for its own self-regulation or Problem Human Control in a humane and wise manner. HEC stands for Human Elephant Conflict, one of our focuses of this conference. How I wish it could come to stand for Human Elephant Coexistence, based on a recognition that other beings also need their space to live in. We are a long way from that, but I am sure that many of the findings of the talented body of researchers in this room will begin a stepwise progress in answering some of these fundamental problems.”

A few years ago Iain’s organisation STE collaborated with the Sri Lankan Wildlife Conservation Society for research activities aimed at reducing human-elephant conflict. In 2016 when the Sri Lankan government was going to destroy the confiscated illegal African elephant ivory, I made a request for Iain to write a congratulatory message to Sri Lanka’s President and Prime Minister for the wise decision they had taken. Iain sent me a four-page meaningful letter written by him, and he was joined by 18 other conservation organisations. In his letter he mentioned, “I want to offer my congratulations to the government of Sri Lanka for the laudable decision to destroy ivory stocks…” Sri Lanka is sending a message to the world that ivory should be without worth; elephants have value when alive. This is a critical message to send, particularly to the religious world, as they are sensitised about the threat religious ivory poses to elephant populations in Africa.”

Fortunately, Iain’s conservation is taken up by his children, especially his eldest daughter, Saba. In 2016 and 2024 she came to Sri Lanka for a lecture hosted by the Galle Literary Festival. Also in 2019, for the Wildlife and Nature Protection Society’s 125th Anniversary, Saba and her husband visited a gala dinner that was held to fundraise for conservation projects.

A difficult path

Iain’s path was never easy. He endured personal peril many times: from hostile terrain and unpredictable wild animals to being shot at by poachers while conducting aerial patrols over war-torn national parks.

Yet despite the danger, despite setbacks — flooded camps, lost data, shifting political tides — his conviction never wavered. His was a life marked by resilience. He refused complacency. He refused to surrender. And through every hardship, he remembered why he began: to give elephants a future.

Iain was also a pilot, and as the old English saying goes, “Pilots don’t die; they simply fly higher.” In that spirit, I wish the same peaceful ascent for Iain. My heartfelt condolences are with Iain’s family.

Awesome power of gratitude

Published

on

When you hear the word gratitude the first impression you get is a tail-wagging dog. If you feed a dog one day, it will wag its tail even if you meet it after a few years. That is gratitude. In addition, dogs are great teachers. They are at home in the world. They live in the moment and they force us to stay with them. Dogs love us and remain grateful unconditionally not for our bodies or bank accounts.

Small children are taught to say ‘Thank you’ for any favour they receive from others. They do not know that the two words can have positive effects on your health and the well-being of others.

Some time ago I had to call emergency services as I found one of my family members was unconscious. Within minutes an ambulance arrived and the paramedics whisked the patient away to the nearest hospital. He was in intensive care for a few days and returned home. We were marvelled at the impact of a handful of strangers who took charge of the patient at a critical time. I immediately wrote thank you notes to those who saved the patient’s life. I knew that it was a small gesture on my part. However, it was the only way I could express my gratitude to a dedicated team.

Selfless people

Later I realized that there are a large number of selfless people who do life-saving work, but they never expect anything in return. How volunteers saved a large number of flood victims is a case in point. The flood victims may not have expressed their gratitude in so many words. However, they would have felt a deep sense of gratitude to the volunteers who saved them.

Why do people come forward to help those facing natural disasters and other dangerous situations? A recent research in the United States shows that sharing thoughts of gratitude and performing acts of kindness can boost your mood and have other positive effects on your health. Almost all religions teach that gratitude does have a good impact on your happiness. Professor of Psychology Willibald Ruch says that gratitude is among the top five predictors of happiness.

By showing gratitude you can make positive changes in your own life. If you feel a sense of gratitude whenever you receive something that is good for you, it will be a healthy sign. You cannot get such a feeling in a vacuum because others have to play their roles. They can be your loved ones, friends, strangers or even people in authority. Gratitude is how you relate to them when you see yourself in connection with things larger than yourself.

Gratification lifestyle

Strangely, many people do not pause to appreciate what others are doing for them. For this you have to blame your gratification lifestyle. With the popularity of social media the young people feel that they are the centre of the universe. They seem to think there is no necessity to thank those who help them.

Why should we thank others even for minor favours? Recent studies show that those who express gratitude increase their own happiness levels. They also lower their blood pressure levels to a great extent. On the other hand, they will be able to sleep well and improve their relationships. They are also less affected by pain because of the positive impact on their depression.

They may not know that positive effects of gratitude are long lasting. Research shows that those who write thank you notes improve their mental health. There was also a decrease in their bodily pains. What is more, they feel more energetic in completing their daily activities. Unfortunately, schools and universities do not teach the value of gratitude since it is fairly a new field of study. Researchers are still trying to find out its cause and effect relationship. We know that those who perform acts of gratitude can sleep well. However, we do not know the reason for it. Researchers are wondering whether gratitude leads to better sleep or sleep leads to more gratitude. They also probe whether there is another variable that leads to gratitude and improved sleep.

Children

Despite such controversies, we know for certain that gratitude can benefit people at any stage of life. Most elderly people remain grateful for their children and grandchildren who support them. Elderly people cannot regain their physical strength or mental agility. Therefore they focus on gratitude. They are thankful to their children and grandchildren for their present situation.

How do gratitude recipients react? Research shows that those who receive thank you notes or acts of kindness experience positive emotions. You feel happy when someone holds a door open for you. Similarly, you are happy if you receive some unexpected help. Recently I was pleasantly surprised to see that someone has credited a big sum of money to my bank account in appreciation of a small favour I had done.

When you thank someone they are more likely to return the favour or pay kindness forward. Psychologically, people feel very happy when you thank them. However, some people hesitate to say thank you. The give-and-take of gratitude deepens relationships. In a close relationship husbands and wives do not thank each other. However, there are other ways of showing gratitude. A wife can make her husband feel appreciated. Such a feeling of appreciation will go a long way to strengthen their relationship.

Some people are ungrateful by nature. However, they can learn the art of being grateful. Such people will do well to maintain a gratitude journal. It is something similar to Pinpotha maintained by Buddhists in the past. They can record positive events in the journal. At the beginning this may not be easy. With practice, however, you can do it well. I knew of a man who kept a gratitude journal. Although his family members laughed at him, he did not give up the habit. When he was diagnosed with a terminal disease he used to read his gratitude journal very happily.

Another Christmas, Another Disaster, Another Recovery Mountain to Climb

Published

on

In line with its overall response to Cyclone Ditwah that devastated many parts of Sri Lanka, India has undertaken to set up temporary Bailey Bridges at selected locations. Work on the first such bridge has begun in Kilinochchi on the Paranthan–Karaichi–Mullaitivu A35 road. Indian Army engineers are working with their counterparts. The Indian HC said that 185 tonnes of Bailey Bridge units were airlifted to restore critical connectivity, along with 44 engineers (Pic courtesy IHC)

The 2004 Asian Tsunami erupted the day after Christmas. Like the Boxing Day Test Match in Brisbane, it was a boxing day bolt for Indonesia, Thailand, Sri Lanka, India and Maldives. Twenty one years later, in 2025, multiple Asian cyclones hit almost all the old victims and added a few more, including Malayasia, Vietnam and Cambodia. Indonesia and Sri Lanka were hit hard both times. Unlike the 2004 Tsunami, the 2025 cyclones made landfalls weeks before Christmas, during the Christian Season of Advent, the four-week period before Christmas preparing for the arrival of the Messiah. An ominously adventus manifestation of the nature’s fury.

Yet it was not the “day of wrath and doom impending … heaven and earth in ashes ending” – heavenly punishment for government lying, as an opposition politician ignorantly asserted. By that token, the gods must have opted to punish half a dozen other Asian countries for the NPP government’s lying in Sri Lanka. Or all those governments have been caught lying. Everyone is caught and punished for lying, except the world’s Commander in Chief for lying – Donald J. Trump. But as of late and none too sooner, President Trump is getting his punishment in spades. Who would have thought?

In fairness, even the Catholic Church has banished its old hymn of wrath (Dies irae, dies illa) that used to be sung at funerals from its current Missals; and it has on offer, many other hymns of peace and joy, especially befitting the Christmas season. Although this year’s Christmas comes after weeks of havoc caused by cyclonic storms and torrential rains, the spirit of the season, both in its religious and secular senses, will hopefully provide some solace for those still suffering and some optimism to everyone who is trying to uplift the country from its overflowing waterways and sliding slopes.

As the scale of devastation goes, no natural disaster likely will surpass the human fatalities that the 2004 Tsunami caused. But the spread and scale of this year’s cyclone destruction, especially the destruction of the island’s land-forms and its infrastructure assets, are, in my view, quite unprecedented. The scale of the disaster would finally seem to have sunk into the nation’s political skulls after a few weeks of cacophonic howlers – asking who knew and did what and when. The quest for instant solutions and the insistence that the government should somehow find them immediately are no longer as vehement and voluble as they were when they first emerged.

NBRO and Landslides

But there is understandable frustration and even fear all around, including among government ministers. To wit, the reported frustration of Agriculture Minister K.D. Lalkantha at the alleged inability of the National Building Research Organization (NBRO) to provide more specific directions in landslide warnings instead of issuing blanket ‘Level 3 Red Alerts’ covering whole administrative divisions in the Central Province, especially in the Kandy District. “We can’t relocate all 20 divisional secretariats” in the Kandy District, the Minister told the media a few weeks ago. His frustration is understandable, but expecting NBRO to provide political leaders with precise locations and certainty of landslides or no landslides is a tall ask and the task is fraught with many challenges.

In fairness to NBRO and its Engineers, their competence and their responses to the current calamity have been very impressive. It is not the fault of the NBRO that local disasters could not be prevented, and people could not be warned sufficiently in advance to evacuate and avoid being at the epicentre of landslides. The intensity of landslides this year is really a function of the intensity and persistence of rainfall this season, for the occurrence of landslides in Sri Lanka is very directly co-related to the amount of rainfall. The rainfall during this disaster season has been simply relentless.

Evacuation, the ready remedy, is easier said than socially and politically done. Minister Lal Kantha was exasperated at the prospect of evacuating whole divisional secretariats. This was after multiple landslides and the tragedies and disasters they caused. Imagine anybody seriously listening to NBRO’s pleas or warnings to evacuate before any drop of rainwater has fallen, not to mention a single landslide. Ignoring weather warnings is not peculiar to Sri Lanka, but a universal trait of social inertia.

I just lauded NBRO’s competence and expertise. That is because of the excellent database the NBRO professionals have compiled, delineating landslide zones and demarcating them based on their vulnerability for slope failure. They have also identified the main factors causing landslides, undertaken slope stabilization measures where feasible, and developed preventative and mitigative measures to deal with landslide occurrences.

The NBRO has been around since the 1980s, when its pioneers supplemented the work of Prof. Thurairajah at Peradeniya E’Fac in studying the Hantana hill slopes where the NHDA was undertaking a large housing scheme. As someone who was involved in the Hantana project, I have often thought that the initiation of the NBRO could be deemed one of the positive legacies of then Housing Ministry Secretary R. Paskaralingam.

Be that as it may, the NBRO it has been tracking and analyzing landslides in Sri Lanka for nearly three decades, and would seem to have come of age in landslides expertise with its work following 2016 Aranayake Landslide Disaster in the Kegalle District. Technically, the Aranayake disaster is a remarkable phenomenon and it is known as a “rain-induced rapid long-travelling landslide” (RRLL). In Kegalle the 2016 RRLL carried “a fluidized landslide mass over a distance of 2 km” and caused the death of 125 people. International technical collaboration following the disaster produced significant research work and the start of a five-year research project (from 2020) in partnership with the International Consortium on Landslides (ICL). The main purpose of the project is to improve on the early warning systems that NBRO has been developing and using since 2007.

Sri Lankan landslides are rain induced and occur in hilly and mountainous areas where there is rapid weathering of rock into surface soil deposits. Landslide locations are invariably in the wet zone of the country, in 13 districts, in six provinces (viz., the Central, Sabaragamuwa, Uva, Northwestern, Western and Southern, provinces). The Figure below (from NBRO’s literature) shows the number of landslides and fatalities every year between 2003 and 2021.

Based on the graphics shown, there would have been about 5,000 landslides and slope failures with nearly 1,000 deaths over 19 years between 2003 and 2021. Every year there was some landslide or slope failure activity. One notable feature is that there have been more deaths with fewer landslides and vice-versa in particular years. In 2018, there were no deaths when the highest number (1,250) of landslides and slope failures occurred that year. Although the largest number in an year, the landslides in 2018 could have been minor and occurred in unpopulated areas. The reasons for more deaths in, say, 2016 (150) or 2017 (250+), could be their location, population density and the severity of specific landslides.

NBRO’s landslide early warning system is based on three components: (1) Predicting rainfall intensity and monitoring water pressure build up in landslide areas; (2) Monitoring and observing signs of soil movement and slope instability in vulnerable areas; and (3) Communicating landslide risk level and appropriate warning to civil authorities and the local public. The general warnings to Watch (Yellow), be Alert (Brown), or Evacuate (Red) are respectively based on the anticipated rainfall intensities, viz., 75 mm/day, 100 mm/day; and 150 mm/day or 100 mm/hr. My understanding is that over the years, NBRO has established its local presence in vulnerable areas to better communicate with the local population the risk levels and timely action.

Besides Landslides

This year, the rain has been relentless with short-term intensities often exceeding the once per 100-year rainfall. This is now a fact of life in the era of climate change. Added to this was cyclone Ditwah and its unique meteorology and trajectory – from south to north rather than northeast to southwest. The cyclone started with a disturbance southwest of Sri Lanka in the Arabian Sea, traversed around the southern coast from west to east to southeast in the Bay of Bengal, and then cut a wide swath from south to north through the entire easterly half of the island. The origin and the trajectory of the cyclone are also attributed to climate change and changes in the Arabian Sea. The upshot again is unpredictability.

Besides landslides, the rainfall this season has inundated and impacted practically every watershed in the country, literally sweeping away roads, bridges, tanks, canals, and small dams in their hundreds or several hundreds. The longitudinal sinking of the Colombo-Kandy Road in the Kadugannawa area seems quite unparalleled and this may not be the only location that such a shearing may have occurred. The damages are so extensive and it is beyond Sri Lanka’s capacity, and the single-term capacity of any government, to undertake systematic rebuilding of the damaged and washed-off infrastructure.

The government has its work cutout at least in three areas of immediate restoration and long term prevention. On landslides warning, it would seem NBRO has the technical capacity to do what it needs to do, and what seems to be missing is a system of multi-pronged and continuous engagement between the technical experts, on the one hand, and the political and administrative powers as well as local population and institutions, on the other. Such an arrangement is warranted because the landslide problem is severe, significant and it not going to go away now or ever.

Such an engagement will also provide for the technical awareness of the problem, its mitigation and the prevention of serious fallouts. A restructuring could start from the assignment of ministerial responsibilities, and giving NBRO experts constant presence at the highest level of decision making. The engagement should extend down the pyramid to involve every level of administration, including schools and civil society organizations at the local level.

As for external resources, several Asian countries, with India being the closest, are already engaged in multiple ways. It is up to the government to co-ordinate and deploy these friendly resources for maximum results. Sri Lanka is already teamed with India for meteorological monitoring and forecasting, and with Japan for landslide research and studies. These collaborations will obviously continue but they should be focused to fill gaps in climate predictions, and to enhance local level monitoring and prevention of landslides.

To deal with the restoration of the damaged infrastructure in multiple watershed areas, the government may want to revisit the Accelerated Mahaweli Scheme for an approach to deal with the current crisis. The genesis and implementation of that scheme involved as many flaws as it produced benefits, but what might be relevant here is to approach the different countries who were involved in funding and building the different Mahaweli headworks and downstream projects. Australia, Britain, Canada, China, Italy, Japan, Sweden and Germany are some of the countries that were involved in the old Mahaweli projects. They could be approached for technical and financial assistance to restore the damaged infrastructure pieces in the respective watershed areas where these countries were involved.
