A 20-year reflection on housing struggles of Tsunami survivors
Revisiting field research in Ampara
by Prof. Amarasiri de Silva
The 2004 Indian Ocean tsunami, also known as the Boxing Day tsunami, triggered by a magnitude 9.1 earthquake off the coast of Sumatra on 26 Dec., 2004, had a catastrophic impact on Sri Lanka. It is estimated to have released energy equivalent to 23,000 Hiroshima-type atomic bombs, wiping out hundreds of communities in minutes. The tsunami struck Sri Lanka’s eastern and southern coasts approximately two hours after the earthquake. The eastern shores, facing the earthquake’s epicenter, bore the brunt of the waves, affecting settlements on the east coast. The tsunami displaced many families and devastated villages and communities in the affected districts of Sri Lanka. Although Boxing Day is associated with exchanging gifts after Christmas and was a time to give to the less fortunate, it brought havoc in Sri Lanka to many communities. It resulted in approximately 31,229 deaths and 4,093 people missing. In terms of the dead and missing numbers, Sri Lanka’s toll was second only to Indonesia (126,804, missing 93,458, displaced 474,619). Twenty-five beach hotels were severely damaged, and another 6 were completely washed away. More than 240 schools were destroyed or sustained severe damage. Several hospitals, telecommunication networks, coastal railway networks, etc., were also damaged. In addition, one and a half million people were displaced from their homes.
Ampara district was a hard-hit district, where more than 10,000 people died. A Galle bound train from Colombo, carrying about 1,700 passengers visiting their ancestral homes and villages, on the Sunday after the Christmas holidays, was struck by the tsunami near Telwatta; most of them were killed.
About 8,000 people were killed in the northeast region, which the LTTE controlled at the time. The Ampara district was a hard-hit district, with more than 10,000 people dying and many more displaced. In sympathy with the victims, the Saudi Arabian government established a grant to construct houses to assist 500 displaced families in Ampara in 2009. The Saudi Envoy in Colombo presented the house keys to President Mahinda Rajapaksa in 2011 for distribution to tsunami victims in the Ampara district. However, due to the protests by local majoritarian ethnic groups, the government intervened, and a court ruling halted the housing distribution to the victims, mandating that houses be allocated according to the country’s population ratio. The project includes residential units and amenities such as a school, a supermarket complex, a hospital, and a mosque, making it unique for Muslim people. Saudi government ambassador Khalid Hamoud Alkahtani engaged in discussions with the Sri Lankan government to sort out the issues and agreed to give the houses to the respective victims.
Immediate Recovery
The immediate relief work was initiated just after the disaster, and the government had financial and moral support from local people and countries worldwide. As most displaced people were children and women, restoring at least basic education facilities for affected children was a high priority. By mid-year, 85 percent of the children in tsunami-affected areas were back in school, which showed that the relief programme in school education was a success.
Relief efforts for households included the provision of finances to meet immediate needs. Compensation of Rs.15,000 (US$150) was offered for victims towards funeral expenses; livelihood support schemes included Payment of Rs.375 (US$3.75) in cash and rations for each member of a family unit per week, a payment of Rs. 2,500 (US$25) towards kitchen utensils per family. These initial measures were largely successful, though there were some problems with a lack of coordination, as witnessed. (See Map 1)
The most considerable financing needs were in the housing sector. The destruction of private assets was substantial (US$700 million), in addition to public infrastructure and other assets. Loss of current output in the fisheries and tourism sectors—which were severely affected—was estimated at US$200 million and US$130 million, respectively.

Strands of Hope: Progress Made for Tsunami-Affected Communities of Sri Lanka
By mid-June 2005, the number of displaced people was down to 516,000 from approximately 800,000 immediately after the tsunami, as people went home—even if the homes in question were destroyed or damaged—and were taken off the books then. At first, an estimated 169,000 people living in schools and tents were mainly transferred to transitional shelters/camps—designed to serve as a stopgap between emergency housing and permanent homes. This transitional shelter was only supplied to affected households in the buffer zone.
By late August 2005, The Task Force for Rebuilding the Nation (TAFREN) estimated that 52,383 transitional shelters, accommodating an estimated 250,000 tsunami-affected people, had been completed since February 2005 at 492 sites. Those transitional housing programme shelters were expected to be completed with 55,000 by the end of September 2005. This goal seems more than achievable. I did not find evidence to show that it has been achieved.
I did my field research in Ampara district with support from UNDP Colombo, the Department for Research Cooperation, and the Swedish International Development Cooperation.
My research shows that the tsunami affected families in Muslim settlements along the East Coast had a severe housing problem for two reasons.
• First, the GoSL has declared that land within 65 meters of the sea is unsafe for living due to possible seismic effects, and people are thus prohibited from engaging in any construction in that beach area. This land strip is the traditional living area of the Muslims, particularly the fisher folk. Families living along the narrow beach strip have not been offered alternative land or adequate compensation to buy land outside the 65-metre zone.
• Second, the LTTE has prohibited Muslims from building houses on land purchased for them by outside agencies on the pretext that it belongs to the Tamils.
The GoSL established several institutions as a response strategy for post-tsunami recovery after the failure of P-TOMS. The Task Force for Rebuilding the Nation (TAFREN), the Task Force for Relief (TAFOR), and the Tsunami Housing Reconstruction Unit (THRU) were the lead agencies created through processes involving private and public sector participation. In November 2005, following the election of President Mahinda Rajapaksa, the Reconstruction and Development Agency (RADA)was set up. This became an authority with executive powers following the parliamentary ratification of the RADA Act in 2006. RADA’s mandate was to accelerate reconstruction and development activities in the affected areas, functionally replacing all the tsunami organizations and a significant part of the former RRR Ministry. According to RADA, the total number of houses built so far (as of May 2006) in Ampara is 629, while the total housing units pledged is 6,169. At the time of the research (March to June 2006), no housing projects were completed in a predominantly Muslim area.
Compensation for damaged houses was not based on a consistent scheme. As a result, some families received large sums, while others did not get any money. In some instances, those who collected compensation were not the affected families. The Auditor General, S.C. Mayadunne, noted that Payment of an excessive amount, even for minor damages, is due to the payments being made without assessing the cost of restoring the houses to normal condition. (For example, Rs. 100,000 had been paid for minor damages of Rs. 10,000) … Payments made without identifying the value of the damaged houses, thus resulting in heavy expenditure by the government (For example, a sum of Rs. 250,000 had been paid for the destruction of a temporary house valued at Rs. 10,000) (Mayadunne, 2005, p. 8). That compensation was not paid according to an acceptable scheme, which led to agitation among the affected people and provided an opportunity for political manipulation. The LTTE and the TRO requested direct aid for reconstruction work in LTTE-controlled areas. The poor response of the GoSL to this demand was interpreted as indifference on its part towards ethnic minorities in Ampara. Meanwhile, the GoSL provided direct support for tsunami-affected communities in southern Sri Lanka, where the majority were Sinhalese, strengthening this allegation.
Land scarcity in tsunami-affected Ampara and disputes over landownership in the area were the main reasons for not completing the housing programmes. The LTTE contended that the land identified for building houses by the GoSL or purchased by civil society organisations for constructing such houses belongs to the Tamils, an ideology based on a myth of their own, a Tamil hereditary Homeland—paarampariyamaana taayakam’ (Peebles, 1990, p. 41). Consequently, housing programmes could not be implemented at that time.
The land question in the Eastern Province has a history that dates back to 1951 when the Gal Oya Colonisation scheme was established. According to the minority version of this history, in a report submitted by Dr. Hasbullah and his colleagues, it shows that the colonists were selected overwhelmingly from among the Sinhalese rather than the Muslims and Tamils, who were a majority in Ampara at that time, and, as a result, the ethnic balance of Ampara District was disrupted. However, conversely, B.H. Farmer reported in 1957 that Tamils, especially Jaffna Tamils, were ‘chary’ and did not have a ‘tradition of migration,’ which was the apparent reason for less Tamil representation among the colonists of Gal Oya. According to Farmer, up to December 31, 1953, between five and 16 percent of the colonists were chosen from the Districts of Batticaloa, Jaffna and Trincomalee, predominantly Tamil. Contradictory evidence (with a political coloring following the recent rise of ethnicity in this discourse) reports by Dr. Hasbullah that 100,000 acres of agricultural land in the East have been ‘illegally transferred from Muslims to the Tamils’ since the 1990s. The Tamils, however, believe that the land in the Eastern Province is part and parcel of the Tamil Homeland. This new political ideology of landownership that emerged at that time in the ethnopolitical context of the Eastern Province has intensified land (re)claiming in Ampara by Muslims and Tamils.
According to Tamil discourse, the increase in the value of land in Ampara over the past two decades has led to rich Muslims purchasing land belonging to poor Tamils, resulting in ethnic homogenization in the coastal areas of the District in favor of the Muslims. ‘Violence against Tamils was also used in some areas to push out the numerically small Tamil service caste communities’ as Hasbullah says. In a situation with an ideological history of land disputes, finding new land for the construction of houses for Muslim communities affected by the tsunami posed a challenge at that time.
In the face of this challenge, Muslims in Ampara sought assistance from Muslim politicians and organisations that willingly came forward to assist them. The efforts made by these politicians and civil society organisations to erect houses for tsunami-affected Muslim families were forcibly curtailed by the LTTE. Consequently, a proposed housing program for Muslims in Kinnayady Kiramam in Kaththankudi was abandoned in 2005. Development of the four acres of land bought by the Memon Sangam in Colombo for tsunami victims of Makbooliya in Marathamunai was prohibited in 2005. Similar occurrences have been reported in Marathamunai Medduvedday. Mrs. Ferial Ashraff, at that time Minister of Housing and Common Amenities, wanted to build houses in Marathamunai, Periyaneelavanai DS division (Addaippallam), the Pandirippu Muslim area, and in Oluvil–Palamunai, but the LTTE proscribed all such initiatives.
The Islamabad housing scheme in Kalmunai Muslim DS division and the construction of houses by Muslim individuals in Karaithivu were banned, and threats were issued by the LTTE and a Tamil military organisation called Ellai Padai (Boundary Forces). Because the GoSL and the intervening agencies could not resolve the housing problem, the affected communities became disillusioned and lost confidence in the GoSL departments, aid agencies, and international NGOs. Much effort and resources were wasted in finding land and designing housing programmes that have not materialised. Some funds pledged by external agencies failed to materialise, causing harm to low-income families. Efforts to provide housing for tsunami-affected people in the Ampara District at that time highlighted their vulnerability to LTTE threats and the power politics of participating agencies. Regarding housing and land issues, the Muslim people of Ampara adopted two approaches to address their challenges. First, in some cases, they reached a compromise with the LTTE, agreeing that upon completion of a housing project, a portion of the houses would be allocated to the Tamil community under LTTE supervision.
For instance, this approach proved successful in the Islamabad housing programme, which was halfway complete as of the time of the research (March–June 2006). Similarly, a housing scheme in Ninthavur followed a comparable compromise with the LTTE. According to Mohamed Mansoor, the then President of the Centre for East Lanka Social Service, 22 of the 100 houses were to be allocated to the Tamil community upon completion. This allocation was deemed reasonable because Muslims owned 80 percent of the land in the area, while Tamils owned 20 percent. At the time of the author’s fieldwork, approximately 30 houses had been completed at this site. I don’t know what happened afterward.
The second approach adopted by the people was to build houses in the areas they had lived in before the tsunami, despite construction being prohibited within 65 meters of the sea. Muslims in Marathamunai knew they would not be allocated any land for housing and sought funds from organisations such as the Eastern Human Economic Development to construct homes on their original plots. The affected individuals have made efforts to urge their leaders to engage with the TRO and the LTTE to reclaim the funds borrowed by Muslim people and organisations to purchase land. The four-acre plot that the Memon Society had acquired for housing development was sold to a Tamil organisation for Rs. 1,000,000 (roughly USD 10,000) and was one such land in question.
The national political forces operating in Ampara have deprived the poor (Muslim) fisher folk of their right to land and build houses in their villages. These communities have resorted to non-violent strategies involving accepting the status quo without questioning it and fighting for their rights. The passivity among the poor affected families is a result of them not having representation in the civil society organisations in the area. These bodies are run by elites who do not wish to contest the GoSL rule of a 65-metre buffer zone or LTTE land claims. The tsunami not only washed away the houses and took the land of the poor communities that lived by the sea, but it also made them even poorer, more marginalised, and more ethnically segregated.
Here, 20 years later, it is time that justice was done to the Muslim families in the Ampara district who were severely hit by the tsunami. It is also a significant and timely commitment made by President Dissanayake to offer 500 houses to the Muslim tsunami victims. Such a promise is overdue and essential, as these marginalised communities have desperately needed a voice and action in their favour for over 20 years. Delivery of such homes to the victims would be an important step in restoring social harmony and the dignity and livelihoods of those affected by the tragic incident.

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