Inside the deadly instant loan app scam that blackmails with nudes
A blackmail scam is using instant loan apps to entrap and humiliate people across India and other countries in Asia, Africa, and Latin America. At least 60 Indians have killed themselves after being abused and threatened. A BBC undercover investigation has exposed those profiting from this deadly scam in India and China.
Astha Sinhaa woke up to her aunt’s panicked voice on the phone. “Don’t let your mother leave the house.” Half-asleep, the 17-year-old was terrified to find her mum Bhoomi Sinhaa in the next room, sobbing and frantic.
Here was her funny and fearless mother, a respected Mumbai-based property lawyer, a widow raising her daughter alone, reduced to a frenzied mess. “She was breaking apart,” Astha says. A panicked Bhoomi started telling her where all the important documents and contacts were, and seemed desperate to get out of the door. Astha knew she had to stop her. “Don’t let her out of your sight,” her aunt had told her. “Because she will end her life.”
Astha knew her mother had been getting some weird calls and that she owed somebody money, but she had no idea that Bhoomi was reeling from months of harassment and psychological torture. She had fallen victim to a global scam with tentacles in at least 14 countries that uses shame and blackmail to make a profit – destroying lives in the process.
The business model is brutal but simple.
There are many apps that promise hassle-free loans in minutes. Not all of them are predatory. But many – once downloaded – harvest your contacts, photos and ID cards, and use that information later to extort you.
When customers don’t repay on time – and sometimes even when they do – they share this information with a call centre where young agents of the gig economy, armed with laptops and phones are trained to harass and humiliate people into repayment.
At the end of 2021, Bhoomi had borrowed about 47,000 rupees ($565; £463) from several loan apps while she waited for some work expenses to come through. The money arrived almost immediately but with a big chunk deducted in charges. Seven days later she was due to repay but her expenses still hadn’t been paid, so she borrowed from another app and then another. The debt and interest spiralled until she owed about two million rupees ($24,000; £19,655).
Soon the recovery agents started calling. They quickly turned nasty, slamming Bhoomi with insults and abuse. Even when she had paid, they claimed she was lying. They called up to 200 times a day. They knew where she lived, they said, and sent her pictures of a dead body as a warning.
As the abuse escalated they threatened to message all of the 486 contacts in her phone telling them she was a thief and a whore. When they threatened to tarnish her daughter’s reputation too, Bhoomi could no longer sleep.
She borrowed from friends, family and more and more apps – 69 in total. At night, she prayed the morning would never come. But without fail at 07:00, her phone would start pinging and buzzing incessantly.
Eventually, Bhoomi had managed to pay back all of the money, but one app in particular – Asan Loan – wouldn’t stop calling. Exhausted, she couldn’t concentrate at work and started having panic attacks.
One day a colleague called her over to his desk and showed her something on his phone – a naked, pornographic picture of her. The photo had been crudely photoshopped, Bhoomi’s head stuck on someone else’s body, but it filled her with disgust and shame. She collapsed by her colleague’s desk. It had been sent by Asan Loan to every contact in her phone book. That was when Bhoomi thought of killing herself.
We’ve seen evidence of scams like this run by various companies all over the world. But in India alone, the BBC has found at least 60 people have killed themselves after being harassed by loan apps. Most were in their 20s and 30s – a fireman, an award-winning musician, a young mum and dad leaving behind their three- and five-year-old daughters, a grandfather and grandson who got involved in loan apps together. Four were just teenagers.
Most victims are too ashamed to speak about the scam, and the perpetrators have remained, for the most part, anonymous and invisible. After looking for an insider for months, the BBC managed to track down a young man who had worked as a debt recovery agent for call centres working for multiple loan apps.
Rohan – not his real name – told us he had been troubled by the abuse he had witnessed. Many customers cried, some threatened to kill themselves, he said. “It would haunt me all night.” He agreed to help the BBC expose the scam.
He applied for a job in two different call centres – Majesty Legal Services and Callflex Corporation – and spent weeks filming undercover. His videos captured young agents harassing clients. “Behave or I will smash you,” one woman says, swearing. She accuses the customer of incest and, when he hangs up, she starts laughing. Another suggests the client should prostitute his mother to repay the loan.
Rohan recorded over 100 incidents of harassment and abuse, capturing this systematic extortion on camera for the first time. The worst abuse he witnessed took place at Callflex Corporation, just outside Delhi. Here, agents routinely used obscene language to humiliate and threaten customers. These were not rogue agents going off-script – they were supervised and directed by managers at the call centre, including one called Vishal Chaurasia.
Rohan gained Chaurasia’s trust, and together with a journalist posing as an investor, arranged a meeting at which they asked him to explain exactly how the scam works.
When a customer takes out a loan, he explained, they give the app access to the contacts on their phone. Callflex Corporation is hired to recover the money – and if the customer misses a payment the company starts hassling them, and then their contacts. His staff can say anything, Chaurasia told them, as long as they get a repayment.
“The customer then pays because of the shame,” he said. “You’ll find at least one person in his contact list who can destroy his life.”
We approached Chaurasia directly but he did not want to comment. Callflex Corporation did not respond to our efforts to contact them.
One of the many lives destroyed was Kirni Mounika’s. The 24-year-old civil servant was the brains of her family, the only student at her school to get a government job, a doting sister to her three brothers. Her father, a successful farmer, was ready to support her to do a masters in Australia.
The Monday she took her own life, three years ago, she had hopped on her scooter to go to work as usual. “She was all smiles,” her father, Kirni Bhoopani, says.
It was only when police reviewed Mounika’s phone and bank statements that they found out she had borrowed from 55 different loan apps. It started with a loan of 10,000 rupees ($120; £100) and spiralled to more than 30 times that. By the time she decided to kill herself, she had paid back more than 300,000 rupees ($3,600; £2,960).
Police say the apps harassed her with calls and vulgar messages – and had started messaging her contacts.

Mounika’s room is now a makeshift shrine. Her government ID card hangs by the door, the bag her mum packed for a wedding still lying there.
The thing that upsets her father the most is that she hadn’t told him what was going on. “We could have easily arranged the money,” he says, wiping tears from his eyes. He’s furious at the people who did this. As he was taking his daughter’s body home from the hospital her phone rang and he answered to an obscenity-laden rant. “They told us she has to pay,” he says. “We told them she was dead.” He wondered who these monsters could be.
Hari – not his real name – worked at a call centre doing recovery for one of the apps Mounika had borrowed from. The pay was good but by the time Mounika died he was already feeling uneasy about what he was part of. Although he claims not to have made abusive calls himself – he says he was in the team that made initial polite calls – he told us managers instructed staff to abuse and threaten people.
The agents would send messages to a victim’s contacts, painting the victim as a fraud and a thief. “Everyone has a reputation to maintain in front of their family. No-one is going to spoil that reputation for the measly sum of 5,000 rupees,” he says.
Once a payment had been made the system would ping “Success!” and they would move on to the next client.
When clients started threatening to take their own lives nobody took it seriously – then the suicides started happening. The staff called their boss, Parshuram Takve, to ask if they should stop. The following day Takve appeared in the office. He was angry. “He said, ‘Do what you’re told and make recoveries,'” Hari says. So they did. A few months later, Mounika was dead.
Takve was ruthless. But he wasn’t running this operation alone. Sometimes, Hari says, the software interface would switch to Chinese without warning. Takve was married to a Chinese woman called Liang Tian Tian. Together, they had set up the loan recovery business, Jiyaliang, in Pune, where Hari worked.

In December 2020, Takve and Liang were arrested by police investigating a case of harassment and released on bail a few months later. In April 2022 they were charged with extortion, intimidation and abetment of suicide. By the end of the year they were on the run.
We couldn’t track down Takve. But when we investigated the apps Jiyaliang worked for, it led us to a Chinese businessman called Li Xiang. He has no online presence, but we found a phone number linked to one of his employees and, posing as investors, set up a meeting with Li.
With his face shoved uncomfortably close to the camera, he bragged about his businesses in India. “We are still operating now, just not letting Indians know we are a Chinese company,” he said.
Back in 2021, two of Li’s companies had been raided by Indian police investigating harassment by loan apps. Their bank accounts had been frozen. “You need to understand that because we aim to recover our investment quickly, we certainly don’t pay local taxes, and the interest rates we offer violate local laws,” he says.
Li told us his company has its own loan apps in India, Mexico and Colombia. He claimed to be an industry leader in risk control and debt collection services in South East Asia, and is now expanding across Latin America and Africa – with more than 3,000 staff in Pakistan, Bangladesh and India ready to provide “post-loan services”.
Then he explained what his company does to recover loans. “If you don’t repay, we may add you on WhatsApp, and on the third day, we will call and message you on WhatsApp at the same time, and call your contacts. Then, on the fourth day, if your contacts don’t pay, we have specific detailed procedures.
“We access his call records and capture a lot of his information. Basically, it’s like he’s naked in front of us.”
Bhoomi Sinha could handle the harassment, the threats, the abuse and the exhaustion – but not the shame of being linked to that pornographic image.
“That message actually stripped me naked in front of the entire world,” she says. “I lost my self-respect, my morality, my dignity, everything in a second.”
It was shared with lawyers, architects, government officials, elderly relatives and friends of her parents – people who would never look at her in the same way again. “It has tarnished the core of me, like if you join a broken glass, there will still be cracks on it,” she says.
She has been ostracised by neighbours in the community she has lived in for 40 years. “As of today, I have no friends. It’s just me I guess,” she says with a sad chuckle.
Some of her family still don’t speak to her. And she constantly wonders whether the men she works with are picturing her naked.
The morning that her daughter Astha found her she was at her lowest ebb. But it was also the moment she decided to fight back. “I don’t want to die like this,” she decided.
She filed a police report but has heard nothing since. All she could do was change her number and get rid of her sim card – and when Astha started receiving calls her daughter destroyed hers too. She told friends, family and colleagues to ignore the calls and messages and, eventually, they all but stopped.
Bhoomi found support in her sisters, her boss and an online community of others abused by loan apps. But mostly, she found strength in her daughter.
“I must have done something good to be given a daughter like this,” she says. “If she hadn’t stood by me then I would have been one of the many people who’ve killed themselves because of loan apps.”
We put the allegations in this report to Asan Loan – and also, through contacts, to Liang Tian Tian and Parshuram Takve, who are in hiding. Neither the company nor the couple responded.
When asked for comment, Li Xiang told the BBC that he and his companies comply with all local laws and regulations, have never run predatory loan apps, have ceased collaboration with Jiyaliang, the loan recovery company run by Liang Tian Tian and Parshuram Takve, and do not collect or use customers’ contact information.
He said his loan recovery call centres adhere to strict standards and he denied profiting from the suffering of ordinary Indians.
Majesty Legal Services deny using customers’ contacts to recover loans. They told us their agents are instructed to avoid abusive or threatening calls, and any violation of the company’s policies results in dismissal.

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.
