Prof Ranga Dias and team make world’s first-ever room-temperature superconductor

By Sajitha Prematunge

It is not a vaccine for COVID-19, but it could be the next best thing. The world’s first superconductor at room temperature, developed by a research team lead by Sri Lankan born physicist, Prof. Ranga Dias at the University of Rochester, USA, could potentially revolutionise everything from transport to energy industry.

The team recently discovered carbonaceous sulphur hydride (CSH), a new compound that acts as a superconductor at 15 °C at a pressure of 267 Giga Pascals (Gpa), or 2.6 million atmospheres (75 percent of the pressure at the earth’s core). The heady article in Nature magazine, which published this groundbreaking discovery in its cover story on October 15, may sound gobbledygook for some. Consequently, The Island interviewed University of Rochester, USA, Department of Physics and Astronomy and Department of Mechanical Engineering, Assistant professor Prof. Ranga Dias; Ph.D. student in Physics, Hiranya Pasan and Ph.D. candidate in Optics, Ashan Ariyawansa to put things in perspective.

A superconductor is a materiel that poses no electrical resistance. “We used two diamonds, each approximately 150 to 200 micron in diameter, on top of each other, to make what’s called a diamond anvil cell. The sample was sandwiched between the two diamonds and pressure applied.” Pasan explained that they could achieve pressures of up to 500 Giga Pascals with the diamond anvil cell. “For comparison, that’s more than the pressure at the earth’s core,” said Pasan. “The diamond anvil cell acts as a materiel search engine, that we use to test material at different pressure until we found the ideal conditions to achieve superconductivity for each material, allowing us to determine which materiel is the most effective. And the result was CSH, a compound belonging to a new class of dense hydrogen rich material.

 

What took so long?

Even though their work was based on old theory, in existence for more than a century, there is still a lot of unknowns. “Even established theory does not explain the mechanism that goes into the making of a superconducting material,” said Dias. But they had two criteria going for them, the ideal superconductor should be of a lighter element that can make stronger bonds. This was the basic premise under which Dias and his team started working with carbon and sulphur. “Our success depended on the right elemental combination,” said Dias, a researcher on high-pressure physics, who had been working with carbon and sulfur for just over a decade.

Pressure variations can convert basic elements of the periodic table into something completely different. Dias explained complex high-pressure physics with a simple analogy. There are two people in a room who can’t interact with each other because they are on opposite corners of the room. Now have the walls close in on them until they are able to talk, shake hands and interact. “The same principle can be applied to elements. When pressurized, atoms and molecules become more interactive and make new bonds. This alters the actual chemical nature of the compound. That’s the beauty of high-pressure physics, it allows you to manipulate the identity of compounds to create whole new material with completely unexpected properties,” said Dias.

 

Previous research

Dias holds a Bachelor of Science degree from the University of Colombo. He turned his attention to metallic hydrogen research as an extension of his PhD research on high-pressure physics at the University of Washington. In 2017, Dias, then a postdoctoral fellow at Harvard University and Isaac Silvera, physicist at Harvard announced the discovery of metallic hydrogen in the Science magazine. Their experiment involved compressing hydrogen gas, which liquifies when cooled to minus 423 degrees Fahrenheit (minus 252.778 Celsius), and then solidifying it at lower temperatures. The claim came under heavy criticism for being based on a single observation, on reflectivity (an expected signature of metallic hydrogen), and without a direct measurement of the pressure involved. The original ‘metallic hydrogen’ sample was lost during the subsequent failure of the diamond anvil cell. Prof. Dias said: “It was a complete study. What is left is to describe the properties of metallic hydrogen, which we are actively working on. Research takes time. None of these experiments are easy.” He joined the University of Rochester, in 2017 as a professor, and is currently conducting further research on metallic hydrogen. He further explained that the Harvard group measured the pressure directly using standard methods that any high-pressure scientist used. Every high-pressure experiment ended with the failure of the diamond anvil cell, which means the loss of the sample. Consequently, Dias argued that there was nothing unusual about the fact that their diamond broke, resulting in the loss of the sample. “I think fellow competitors who were trying to make metallic hydrogen wasn’t happy that we got it right, their criticism has nothing to do with science but rather was a political attack on my previous advisor [Silvera].”

When asked how positive he is about the newly discovered carbonaceous sulphur hydride, in light of the previous backlash, Dias said that he doubted there was a connection. “They are two different experiments and very different samples. The hallmark of superconductivity is the complete absence of electrical resistance. And another property of superconducting materials is that when it is cooled below the superconducting transition temperature, the magnetic field lines are expelled from the material. We have observed both of these key properties on our carbonaceous sulphur hydride materials at high pressures.” Dias confident of the results.

Prof. Dias’ finding has definitely sparked investor interest. In fact, investors are already lining up to fund a research company, by the name of ‘Unearthly Materials’, set up under the leadership of Prof. Dias to carry out further research and to manufacture superconductors on a large scale. A financial capital of US $ 2 million, has already been provided by investors. Dias hopes it will culminate in a highly productive venture in three to five years.

 

Implications

Prof. Dias believes that the technology could open up a world of possibilities for medical imaging such as MRI, computing and consumer electronics such as mobile phones. Applications of his discovery include low-cost MRI scanners, magnetic levitation trains, and power lines with no electrical resistance. “A computer, for example, has a heavy cooling system with heat sink, fans and the like, but with a superconductor none of these will be necessary,” explained Hiranya Pasan, who was tasked with low temperature analysis in this research. With this kind of tech everything from car radiators to train tracks could become redundant. “A huge amount of energy is lost in transmission per year. It adds up to a lot of money,” pointed out Pasan. So, if someone were to mass produce superconducting wire, which offers no electrical resistance, he would save billions of or dollars for countless governments.

And then there is the Meissner effect, which in layman’s terms means to repel a magnet. Superconductors are strongly diamagnetic and expel magnetic fields. As such trains could employ magnets that levitate on superconducting material. “It produces no friction,” explained Pasan. Such frictionless high-speed trains could revolutionise the transport sector.

“The technology already exists,” explained Dias. Superconducting technology is used in MRI scanners, particle accelerators, and magnetic levitation trains of experimental scale in Japan, all of which involves large magnetic fields. “But it requires cryogenics.” Meaning that some metals reach superconductivity at extremely cold temperatures and, therefore, have to be cooled to about 10 to 20 Kelvin. For context, that’s minus 263.15 to 253.15 Celsius. The critical temperature of the first superconductor, discovered in 1911, was minus 269 °C, and the fact that no research has ever been able to find a material that acts as a superconductor in room temperature has been one of the major challenges in physics.

“The cryogenic factor is what makes the technology so expensive and therefore economically unviable,” pointed out Dias. So, if cryogenics were to be taken out of the equation, it would make medical imaging, for example, much more affordable and efficient. Prof. Dias explained that liquid helium is the most widely used coolant in superconducting applications, a resource fast diminishing.

He and his team were able to take the cryogenics out of the equation, but maintaining such gargantuan pressures make mass production of superconducting material virtually impossible. When asked how stable the new compound was Dias explained that CSH could be metastable, meaning that it may not revert to the original compound of carbon and sulphur once pressure is relieved. If not, it’s back to square one for the team as they would have to find another compound that acts as a superconductor at both room temperature and atmospheric pressure. The team revealed that they would conduct the ultimate experiment by relieving pressure, in the weeks to come, which Pasan has been tasked with. “Once we have a metastable superconducting material at ambient pressure, it’s just a matter of replicating it, using techniques like chemical deposition and Molecular-beam epitaxy (MBE), to achieve mass production.” Those were the standard techniques and therefore were affordable, he said.

Ground-breaking discoveries are made every few decades in the western world and they have little or no effect at all on developing nations such as Sri Lanka. So why is a superconductor at room temperature even significant for a country like Sri Lanka? “I don’t think that the GDP matters in terms of implications of such discoveries, said Dias. “What is rocket science is developing a superconductor at room temperature. When that’s a reality, application comes easy. Whether it was frictionless trains or MRI scanners, such technology can always be applied by replacing the existing technology with the new.”

 

Application of such technology in quantum computing would be difficult for a country like Sri Lanka, but Dias pointed out that the implications of the technology for energy transmission was of considerable significance to developing countries. As Pasan pointed out, a lot of electricity is lost during transmission. Dias argued that with a superconducting wire, that pose no resistance, third world power generation can be made more efficient, thereby increasing capacity. “This kind of application is not difficult to apply even in a developing country.” Dias assured that such technology would be affordable even for developing countries.

 

Local students

When asked about the practical difficulties Sri Lankan students have to face, Hiranya pointed out that as opposed to Sri Lanka, the US has a more student-centred education system, while Dias said there was a clear lack of enthusiasm for research in Sri Lanka. “During my time in Sri Lanka, we were hardly exposed to experiments, we rarely saw instruments, except at practicals during undergraduate years, simply because we didn’t have the facilities,” said Prof. Dias. “The system is exam-oriented, and as a result we lacked hands on experience.” Dias pointed out that in the US education system there was ample opportunity for research. “Even the exam questions here are very practical. It hones critical thinking instead of promoting memorising equations and just getting good grades.” Such a system increases research productivity, he said.

“Research lacks support in Sri Lanka, especially in terms of funding,” said Dias. “In the States we can acquire federal, corporate and other sources of funding. But in Sri Lanka we don’t have that kind of a mechanism.”

But things are looking up, said Ariyawansa. “Collaborative research on chemistry and biotechnology is undertaken increasingly in Sri Lanka,” he said, pointing out that industrial chemistry and nanotechnology were fast developing areas, but he admitted that physics was still lagging behind. “We now have institutions such as SLINTEC [Sri Lanka Institute of Nanotechnology], which has succeeded in attracting a lot of expatriate academics back into the country,” added Dias. He opined that such infrastructural support and funding would facilitate cutting-edge research.

When asked whether such cutting-edge research would have any practical applications in Sri Lanka and whether putting so much money and effort into research was viable in the absence of practical applications, Prof. Dias said that there would always be opportunities in terms of putting research into practice. “Commercial production of graphene by SLINTEC is a case in point. It’s a direct application. I’m sure that if Sri Lanka can produce high grade graphene, we can export it. Graphene has a lot of applications, especially in electronics. It’s used widely in the US, Japan, Europe and South Korea for semiconductor and mobile applications.”

The same principle can be applied to diamonds. “With the right combinations of material diamonds can be grown in the lab,” Dias pointed out that this could revolutionise the diamond industry. “This is already being done in the US,” said Dias, reiterating that material research would always have applications.

Octopus, Leech, and Snake: How Sri Lanka’s banks feast while the nation starves

Published

on

Open any business newspaper in Sri Lanka on any given weekend and the headlines read like a celebration. Bank A’s assets have crossed Rs. 3 trillion. Bank B has reached the Rs. 2 trillion asset milestone. Bank C has posted a profit after tax of Rs. 6 billion in the first quarter of 2026 alone. Bank E has reported a profit before tax of Rs. 2 billion. Bank E has cleared Rs. 1.5 billion in pre-tax profit. Bank F revealed a profit after tax of Rs. 4 billion. The numbers are staggering in a country where per capita income remains fragile, the economic crisis of 2022 has left deep scars, and some 300,000 small and medium entrepreneurs are reportedly at risk of losing the roofs over their heads, and their businesses.

So, the question must be asked, loudly and without apology: how do Sri Lankan banks manufacture such colossal profits, and who, precisely, is paying for them?

The arithmetic of extraction

The answer lies in a three-digit spread that most depositors and borrowers never see printed side by side. Sri Lanka’s Central Bank has held its Overnight Policy Rate (OPR) at 7.75%, the mid-point of a corridor bounded by a Standing Deposit Facility Rate of 7.25% and a Standing Lending Facility Rate of 8.25%; a policy spread of a mere 1%. This is the rate at which banks lend to and borrow from the Central Bank overnight. It is the peg around which monetary policy turns. What happens when that peg meets the market is another story altogether.

A depositor walking into a Sri Lankan bank today will be offered somewhere between 6% and 9% on a fixed deposit, the rate varying by tenure, bank, and whether you qualify as a “senior citizen.” Average savings account rates sit between 2% and 5%, while fixed deposits offer 6% to 10%. Yet, the same bank will charge that depositor’s neighbour, who runs a hardware shop, a garment workshop, or a small hotel, between 14% and 24% to borrow. Credit cards carry rates at the upper end or beyond that range. The arithmetic is unambiguous: an interest spread of 8 to 14 percentage points, engineered on top of a policy rate corridor of just 1%.

A key driver of lending interest rates is the lending-deposit interest spread, which captures the efficiency with which banks allocate society’s savings to its most productive uses. High lending rates and spreads pose a challenge for policymakers: they can affect monetary policy transmission, hinder private investment and job creation, inhibit financial development and inclusion, and can ultimately compromise financial stability.

Sri Lanka’s spreads fail every one of those tests.

An international comparison that should shame regulators

To understand the scale of this extraction, one need only look at comparable economies. In India, the Reserve Bank’s repo rate stands at 6.5%, and commercial bank lending rates to prime borrowers average around 9–11%, yielding a spread of roughly 3–4 percentage points. Thailand and Vietnam, both developing Asian economies with nominal policy rates in the 2–4% range — maintain bank lending-deposit spreads consistently below 5 percentage points. Many countries in East Asia had average spreads of 5% or less during the 2010–2017 period, including China, South Korea, Japan, Myanmar, Thailand, and Vietnam.

Nepal, whose financial system is frequently and condescendingly compared unfavourably to Sri Lanka’s, reported a bank lending rate of 7.66% in late 2025, a figure that would be considered a floor, not a ceiling, in Colombo. Bangladesh records a lending rate of under 8%. Even Pakistan, whose policy rate touched 22% during a period of acute macroeconomic crisis, has since brought it down sharply, and its spread has never structurally embedded itself at the levels Sri Lankan banks now consider normal.

Move to advanced economies and the contrast becomes almost surreal. Japan’s policy rate remains effectively at zero; bank lending rates for business borrowers sit between 1% and 2.5%. Australia’s Reserve Bank rate stands at 4.35%, with commercial lending to small businesses typically in the 6–8% range, a spread of 2–3 points at most. New Zealand, Canada, and the United States operate within similar parameters: policy-to-lending spreads that are measured in single digits and that tighten competitively as banking markets mature.

Sri Lanka’s banks, by contrast, operate as if competition does not exist, and as if SMEs have nowhere else to go. They are largely correct on both counts.

The three creatures: A taxonomy of bank behaviour

A financial analyst, speaking in a podcast that has circulated widely among the Sri Lankan business community, offered a metaphor that deserves wider currency. Sri Lankan banks, he argued, behave with a three-stage predatory logic.

First, they are the Octopus, embracing customers tightly, wrapping tentacles around every financial transaction, every salary account, every utility payment, every insurance product. The bank becomes indispensable. It is everywhere. Cross-selling, bundling, and lock-in are the tools of this phase. The small businessman who secures a loan quickly finds that his current account, his trade finance, his letter of credit, and his overdraft are all with the same institution. He is held, firmly, from all sides.

Then, once the embrace is complete, comes the Leech, the slow, persistent extraction of blood. The interest rate spread does its patient work over months and years. A loan taken at 18% for a business generating 12% returns is a slow death sentence, mathematically guaranteed. Fees compound on fees. Penal interest accrues on unpaid interest. The CRIB record, Sri Lanka’s Credit Information Bureau system, locks the borrower in place: miss a payment, and no other institution will touch you. The leech feeds undisturbed.

And then, when the blood runs dry, when the business can no longer service its debt and the collateral has been fully leveraged, comes the Snake. Sri Lanka’s Parate Execution Law, enacted under the Recovery of Loans by Banks (Special Provisions) Act No. 4 of 1990, gives licensed commercial banks a power possessed by almost no other creditor class in any comparable jurisdiction: the right to seize and auction mortgaged property without any court order, without any judicial oversight, and without any independent valuation requirement.

Parate Execution is deeply ingrained in Sri Lanka’s legal system and has been a crucial tool for banks in recovering debts. The Cabinet-of-Ministers’ approval for a temporary suspension until December 2024 reflects a response to economic challenges, particularly for small and medium-sized enterprises. In 2023 alone, over 1,750 properties belonging to SMEs were auctioned under the law. These were not abstract balance sheet entries. They were factories, workshops, warehouses, family homes pledged as collateral, and the accumulated savings of a lifetime. Around 10 SME associations are collectively pushing for the continued suspension of parate executions, warning that nearly 300,000 entrepreneurs risk losing their assets if the law is enforced without reforms.

The snake, once it strikes, leaves nothing.

The Gates Prediction and the clever adaptation

Bill Gates, in his 1997 book ‘Business at the Speed of Thought’, famously observed that banking is necessary but banks are not, that the dinosaur institutions of the financial world would be swept aside once the Internet captured the transaction infrastructure that sustains them. A quarter of a century later, the banks are still here, and in Sri Lanka they are more profitable than ever. Gates underestimated the octopus’s adaptability.

Sri Lankan banks did not resist digital disruption; they absorbed it and charged for it. Sri Lankan banks have a genuine claim to technological pioneering. They were among the earliest institutions in the world to deploy automated teller machines and some have argued that the island served as a live testing ground for ATM technology before the technology was ready for larger markets.

Internet banking reduced their branch costs while preserving their pricing power. Mobile apps deepened the lock-in. The spread, the core engine of extraction, was never threatened by technology because technology cannot dissolve a regulatory monopoly or a CRIB record. The dinosaur learned to code.

What did not adapt was the relationship between bank profit and productive economic activity. In a functioning market, high bank profitability should signal efficient intermediation, savings being channelled productively into investment, employment, and growth. In Sri Lanka, it signals the opposite: a structural transfer of income from the productive economy, particularly from small businesses, to the financial statements of financial institutions that operate with insufficient competitive pressure, inadequate regulatory oversight of pricing, and a legal recovery toolkit that would be considered extraordinary in almost any other jurisdiction.

The SME crisis: When the host dies

The damage falls most heavily on small and medium enterprises, the sector that, in Sri Lanka as in every economy in the world, provides between 60% and 80% of all employment and generates the majority of entrepreneurial activity outside the formal corporate sector.

The International Monetary Fund has called for the reinstatement of parate execution, warning that prolonged suspension hinders banks’ ability to manage non-performing loans and price credit risks, potentially destabilizing the financial system. The IMF’s concern is legitimate in principle but perverse in practice. Non-performing loans in Sri Lanka’s banking system did not emerge from borrower profligacy. They emerged from a combination of historically high interest rates, a catastrophic economic crisis that was itself partly the product of fiscal and monetary mismanagement, and a forced-sale recovery mechanism that, when applied during a downturn, a double blow, destroys the very collateral value it claims to protect. When 1,750 properties are auctioned in a single year, supply floods a distressed market and prices collapse, damaging the bank’s recovery as much as the borrower’s livelihood.

What must change

The case for structural reform is not a case against banking or against profitable financial institutions. It is a case against a system that has substituted regulatory capture for competitive discipline, and legal coercion for constructive engagement.

Three reforms are overdue and increasingly urgent

.

First, the interest rate spread must be subject to transparent regulatory oversight. The Central Bank publishes the Average Weighted Prime Lending Rate and related statistics, but there is no binding ceiling on the spread between what banks pay depositors and what they charge borrowers for equivalent-risk instruments.

Second, the Parate Execution Law requires comprehensive reform, a genuine rewriting that introduces judicial oversight, mandatory independent valuation, and a structured mediation requirement before any forced sale can proceed.

Third, SME credit must be deliberately repriced. A development banking framework, should offer structured SME lending at regulated spreads, with the Central Bank providing concessional refinancing. Several peer economies have such mechanisms. Sri Lanka has the institutional capacity to build one; what it has lacked is the political will to confront the banking lobby that benefits from the current architecture.

The parasite and the host

There is an ecological principle that even the most effective parasite must learn: if it kills the host, it dies, too. Sri Lanka’s banking sector has not yet killed its host economy, but the symptoms of dangerous over-extraction are visible in every gazette notice of a parate auction, in every shuttered workshop in Pettah, in every garment factory whose owner defaulted not due to bad management but due to the mathematics of an 18% loan in a 12% return environment.

The banks will continue to announce their trillion-rupee asset milestones and their billion-rupee profits. The newspapers will continue to celebrate. And the octopus will continue its embrace, the leech its quiet work, and the snake will wait, patient, unhurried, for the moment to strike. Unless someone intervenes.

Winged guardians of Sri Lanka’s natural heritage: Featured birds highlight biodiversity richness ahead of World Biodiversity Day

Published

on

Crimison Fronted Barbet

As the world prepares to observe the International Day for Biological Diversity, commonly known as World Biodiversity Day, on May 22, Sri Lanka stands as a vivid example of how a relatively small island can hold an extraordinary concentration of life.

The annual observance serves as a global reminder of the importance of protecting ecosystems and the rich variety of life forms that sustain the planet.

This year’s observance comes amid increasing international concern over biodiversity loss driven by habitat destruction, climate change, pollution, invasive species and unsustainable development. Scientists warn that the disappearance of species affects not only wildlife but also food security, water resources, livelihoods and ecological stability.

For Sri Lanka, World Biodiversity Day carries particular significance.

Despite occupying less than 0.03 percent of the Earth’s land surface, Sri Lanka possesses remarkable ecological richness and has earned global recognition as one of the world’s biodiversity hotspots.

The island’s forests, wetlands, rivers, mountains and coastal ecosystems support an extraordinary range of species, many of which are found nowhere else on Earth.

Among the most visible and fascinating representatives of this natural wealth are birds — creatures that fill forests and gardens with colour and song while performing critical ecological functions. Birds pollinate flowers, disperse seeds, regulate insect populations and serve as important indicators of environmental health.

Conservation Biologist Rajika Gamage of the Tea Research Institute says birds often provide the earliest signals of environmental changes taking place within ecosystems.

“Birds are among the most important indicators of habitat quality. Changes in bird populations can reveal ecological disturbances long before they become visible to people,” Gamage said.

Black bird

As Sri Lanka reflects on biodiversity conservation, five remarkable bird species — the Yellow-fronted Barbet, Crimson-fronted Barbet, Sri Lanka Hanging Parrot, Tawny-bellied Babbler and Blackbird — illustrate not only the beauty of the country’s avian diversity but also the interconnected nature of ecosystems.

Sri Lanka’s biological richness is exceptional by global standards. The island contains a high percentage of endemic species among amphibians, reptiles, freshwater fish, mammals and birds. The country’s geographical isolation, varied elevations and diverse climatic conditions have shaped unique evolutionary pathways over millions of years.

Its wet zone rainforests, dry zone forests, montane cloud forests, grasslands and agricultural landscapes collectively create a mosaic of habitats capable of supporting diverse life forms.

Gamage notes that biodiversity conservation extends far beyond protected areas.

“People often think biodiversity exists only inside national parks and forests. But biodiversity is supported through connected landscapes that include home gardens, agricultural lands, tea plantations, wetlands and village ecosystems,” he explained.

Research in plantation landscapes has demonstrated that tea-growing regions with habitat diversity and natural vegetation can support substantial bird populations, including endemic and ecologically important species.

Among the featured birds, the Yellow-fronted Barbet stands as one of Sri Lanka’s most recognisable endemic species.

The bird, with its bright green plumage, yellow forehead and blue facial markings, often remains hidden among dense foliage despite its loud repetitive calls echoing through gardens and forests.

Sri Lanka Hanging Parakeet

While many people hear its calls every day, few realise its importance within ecosystems.

The species feeds heavily on fruits and berries, becoming an important seed disperser. Seeds consumed by the bird are transported and deposited elsewhere, helping natural forest regeneration.

“Many birds function as ecological engineers without people realising it,” Gamage said. “Seed-dispersing species contribute directly to maintaining forest diversity.”

Equally colourful is the Crimson-fronted Barbet.

Distinguished by its vivid crimson forehead against green plumage, this endemic bird inhabits forests and tree-rich landscapes within wetter parts of Sri Lanka.

Like the Yellow-fronted Barbet, it performs a critical ecological function through seed dispersal.

The species often serves as an indicator of healthy vegetation and suitable habitat structure. Its ability to survive in modified landscapes with sufficient tree cover also demonstrates the importance of preserving green corridors beyond forests.

Another unique representative of Sri Lanka’s avian heritage is the Sri Lanka Hanging Parrot.

Tawny Bellied Babbler

Small, energetic and brightly coloured, the bird is famous for its unusual habit of sleeping upside down while hanging from branches.

Its striking appearance makes it popular among birdwatchers, but its ecological significance extends beyond aesthetics.

Feeding on fruits, flowers and nectar, the Hanging Parrot acts both as a pollinator and seed disperser.

As it travels among plants and trees, it assists natural reproductive processes essential for maintaining healthy ecosystems.

“Pollination and seed dispersal are among the foundations upon which ecosystems function,” Gamage explained.

Less conspicuous but equally valuable is the Tawny-bellied Babbler.

Often moving quietly through shrubs and undergrowth in pairs or small groups, the species spends much of its time searching for insects and other small invertebrates.

Unlike fruit-eating birds, the Tawny-bellied Babbler contributes to ecological balance through natural pest control.

Its feeding behaviour helps regulate insect populations, particularly within agricultural landscapes.

Birds that naturally reduce insect numbers provide ecological services that may reduce reliance on chemical pest-control methods.

The Sri Lanka Blackbird occupies yet another important ecological niche.

Found mainly in montane forests and cooler highland environments, the species reflects environmental conditions within sensitive mountain ecosystems.

Scientists often monitor highland bird populations because changes in their distribution or numbers can indicate broader environmental changes, including habitat degradation and climate impacts.

As World Biodiversity Day approaches, experts stress that conservation challenges continue to grow.

Habitat fragmentation, pollution, deforestation and climate-related pressures increasingly threaten ecosystems around the world, including Sri Lanka.

Yet conservationists emphasise that solutions frequently begin at local levels.

Protecting trees in home gardens, restoring degraded habitats, conserving wetlands and promoting biodiversity-friendly agricultural practices can all contribute significantly to preserving ecological balance.

Gamage believes that public understanding remains central to future conservation efforts.

“People should understand that biodiversity is not separate from human life. Clean water, fertile soils, pollination, climate regulation and ecological stability all depend upon biodiversity,” he said.

The songs of Sri Lanka’s birds may appear ordinary to casual listeners, but behind those sounds lies a story millions of years in the making.

The call of a Yellow-fronted Barbet from a village garden, the bright flash of a Hanging Parrot moving across a forest edge, the quiet movements of a Tawny-bellied Babbler beneath dense vegetation, or the presence of a Blackbird in cool mountain forests are all reminders of the extraordinary natural heritage the island possesses.

As Sri Lanka marks World Biodiversity Day alongside the global community, these winged ambassadors become more than beautiful wildlife species.

They represent the fragile yet complex web of life that sustains ecosystems — and ultimately sustains humanity itself.

The Time has come to move forward

Published

President Dissanayake / Minister Rathnayake / Minister Nanayakkara

Time, it is said, is the great healer. But there are some wounds that will not heal with time. They need specific and focused treatment. The dates May 18 and 19, the two final days of Sri Lanka’s three decade long war, are less in the consciousness of the people than before. But the continuation of the untreated and unhealed wounds of the war continues to be seen in the many groups of people who gather to remember their loved ones on these days. In Colombo, a group of victim families and committed activists from different communities gathered at Wellawatte beach and lit lamps. These gatherings are also a political statement that the wounds of the war remain untreated and unhealed.

One of the key features of May 18 and 19 has been the polarised positions taken by Tamil and Sinhalese groups. Tamil groups mourn those who perished in the war, especially in the last battles, on May 18 while many Sinhalese commemorate the military victory on May 19. Since 2015 there has been a diminishing of tensions due to the more nuanced way successive governments have marked the end of the war. This was especially the case during the governments led by Ranil Wickremesinghe and is now also true of the government headed by President Anura Kumara Dissanayake.

The present government has done much to mitigate the sense of polarisation between the state and the ethnic and religious minorities. The government’s insistence that it will treat all citizens equally and not support extremism in any form is appreciated by minorities who have often felt marginalised and viewed with suspicion in the past. But the government cannot afford to rest on its laurels merely because it is better than previous governments. It needs to take specific and focused action to heal the wounds of the past. Symbolic gestures and inclusive rhetoric are important, but they are not enough in themselves to deal with the consequences of a protracted ethnic conflict.

The unresolved issues are well known. They surface repeatedly in the resolutions on Sri Lanka passed at the UN Human Rights Council in Geneva. In 2015 Sri Lanka co-sponsored UN Human Rights Council Resolution 30/1 which called for reconciliation, accountability and constitutional reform including power sharing arrangements. This resolution and the ones that preceded it emerged from the demands of war affected communities and found resonance within the international human rights community. They include the issues of missing persons, disappeared persons, political prisoners, military occupation of civilian lands and accountability for alleged wartime abuses.

Most Capable

Under the NPP government, Tamil people have felt they can attend events commemorating those who died in the war in large numbers. This is evidence that the country is changing in the direction of reconciliation. State institutions too have cooperated in this process in creating a conducive climate for memorialisation. But despite the passage of 17 years since the end of the war, the emblematic issues remain unresolved although the government appears sincere in its desire to resolve them. Indeed, the government has deployed some of its most capable leaders to deal with these challenges.

President Dissanayake himself has taken on the task of reshaping public consciousness through speeches that emphasise unity rather than division. Minister of Justice and National Integration Harshana Nanayakkara has responsibility for institutions dealing with missing persons, reparations and reconciliation. Leader of the House Bimal Rathnayake has been entrusted with accelerating economic development in the north. Economic development is essential. The north and east require investment, jobs, infrastructure and opportunities for young people. Poverty and unemployment affect all communities and development can reduce feelings of exclusion. But economic development alone cannot resolve the deeper roots of ethnic conflict.

Protracted ethnic conflicts are rarely caused only by economic grievances. They are also about identity, dignity, historical memory and political power. This is where many governments in Sri Lanka have failed. They have believed that rapid development, highways, buildings and investment would be sufficient to overcome decades of mistrust. But communities that feel politically marginalized do not simply abandon their aspirations because roads are built or markets expand. Human beings seek recognition of who they are and a meaningful share in the decisions that govern their lives. Language is particularly important. In Tamil majority districts, the government secretariats continue to be staffed by those who are only Sinhala-speaking. This is a constant reminder to Tamil speakers that they are not equal to Sinhalese in their dealings with the state.

Academic research on divided societies has shown that constitutional arrangements can either exacerbate conflict or reduce it. Countries such as Belgium and Northern Ireland provide examples where systems of power sharing have enabled communities with different identities to coexist peacefully within a common state. In Northern Ireland, peace became sustainable only when political institutions ensured that both communities had a guaranteed role in governance rather than leaving one side permanently subordinate to the other. Sri Lanka’s own efforts at political reform have focused largely on territorial power sharing through the 13th Amendment to the Constitution and the provincial council system.

More Belonging

The fact that the government leadership is now saying that provincial council elections will be held this year is therefore a positive development. It would restore democratic participation at the provincial level after years of delay and neglect. However, reforms need to go further. Provincial councils have remained weak institutions with inadequate powers and finances. Successive governments have hesitated to fully implement the provisions of the 13th Amendment, especially regarding land and police powers. These laws, including the language law, need to be fully implemented. The reluctance or incapacity of successive governments to do so, including the present one, has reinforced minority perceptions that promises of devolution are made but never sincerely implemented.

A new national narrative for Sri Lanka must therefore go beyond non racism and economic development. True reconciliation requires accepting diversity not as a threat but as the foundation of a united and peaceful country. Power sharing should not be viewed as a concession extracted under pressure. It should be understood as a democratic necessity in a plural society. The purpose of power sharing and giving equal rights to Tamil language speakers is not division but inclusion. It gives all communities a stake in the state and reduces the fear that political power will permanently remain in the hands of one community alone.

Sri Lanka has had leaders in the past who understood this reality. Prime Minister S W R D Bandaranaike attempted to reach a political settlement through the Bandaranaike Chelvanayakam Pact of 1957. Today the political context offers another opportunity. The nationalist forces that dominated politics for many years have lost credibility due to their association with corruption, economic collapse and political mismanagement. But where they did the right thing they are remembered positively as the late State Minister of Plantation Industries and Mahaweli Development in Sri Lanka Lohan Ratwatte still is in Batticaloa for having heeded the Tamil cattle farmers and appointing a Tamil officer to deal with their problems. The government has a two thirds majority in Parliament and enjoys significant public goodwill. This creates space for courageous leadership.

The time has therefore come for the government, opposition and minority political parties to put aside their bitter political feuds and engage with each other sincerely to arrive at a consensual political solution embedded within the Constitution. Sri Lanka has tried military victory, centralized rule and development centred approaches. None by themselves have resolved the ethnic conflict. The lesson of the past is that non racism and economic development are necessary, but they are not sufficient. Lasting peace in Sri Lanka requires power sharing, trust building and a political settlement that gives every community a sense of belonging to a country they all feel is home.
