SLIIT controversy in the context of establishing private sector higher education institutions in Sri Lanka

By Prof Susirith Mendis
(susmend2610@gmail.com)

Having been a regular contributor to ‘The Island’, I have ventured again into expressing my opinion in public spaces after an extended period of silence, as I felt compelled to, after I read the excellently argued piece by Prof R.P. Gunawardane titled ‘SLIIT should remain non-state and non-profit institution’ in The Island of November 23.

Prof. Gunawardane explains why Sri Lanka Institute of Information Technology (SLIIT) should remain non-state and non-profit. He also discusses dispassionately the ‘issues and concerns’ that have come up in recent times about the unsavoury circumstances under which SLIIT ended up completely under private ownership divesting itself from what they might have seen as ‘the restraining clutches’ of the Mahapola Trust Fund (MTF). Prof Gunawardane’s recommendations finally, as well, are mostly acceptable and valuable.

But there are a few places where I beg to disagree and also wish to extend comment on the two topics he has touched upon.

Leaving the comments about the restraints of the University Grants Commission (UGC) on the state universities for later, let me first take issues about SLIIT.

SLIIT and MTF

Things have ‘hit the fan’ since the COPE report on SLIIT became public. Minister Bandula Gunawardane has assured at a meeting chaired by the President, that in his capacity as Minister of Trade, “action would be taken to take over SLIIT divested through fraudulent means”. The Minister used the words “fraudulent means”. The Island of August 10, 2021 headlined its story on the COPE revelations on SLIIT, ‘COPE tells govt. to undo SLIIT swindle’. So, it has been named fraudulent and a swindle.

The Second Report of the Committee on Public Enterprises tabled in Parliament on April 6, 2021, was a Special Report on SLIIT. The report prepared on the basis of an investigation by the Auditor General’s Department has recommended that “the SLIIT be recognised as a non-governmental institution and that the decision taken by the Cabinet of Ministers on 24.05.2017 not to include the said institution under any purview of the Ministry be reconsidered.” It also recommends that “the institution be taken over by the Mahapola Fund.”

Furthermore, the COPE recommended that action be taken under the Public Property Act against ‘all parties involved’ (my emphasis) in the action taken to deprive the government of its ownership of SLIIT and its control by an agreement signed on May 12, 2015 without any formal authority.

Therein lies the crux of this issue, that Prof Gunawardane failed to emphasise. But Prof Gunawardane rightly questions the bona fides of SLIIT in not responding to the summons of COPE to appear before it, using a technicality and informing, through their law firm, that it is ‘not legally obligated’ to do so. If all the actions of SLIIT in the process of the MTF divesting itself of SLIIT were above board, and there was nothing to hide, this would have been the best opportunity that the management of SLIIT had of publicly declaring that it had clean hands. Their refusal to do so is suspicious to say the least. A subsequent full-page advertisement (for which they must have spent a few cool millions) in The Daily Mirror of October 29, 2021, titled ‘The True Story of SLIIT’ was a varnished narrative signed, sealed and delivered to a gullible public. What was curiously revealing was, therein, they relate in passing, “the great risks and sacrifices made by the pioneers of SLIIT,” in particular those of Prof Lalith Gamage. It is a good advertisement. As good an advertisement as all advertisements are and expected to be, where critical information is suppressed, and high-points are emphasised and overblown. Like advertisements for milk foods or table margarines, for instance.

The refusal of SLIIT to appear before COPE may have prompted Wijeyadasa Rajapakshe to move the Supreme Court in terms of article 126 and Article 17 of the Constitution of Sri Lanka to request the cancellation of agreements between the MTF and SLIIT. The former Minister of Justice as well as Minister of Higher Education under the Yahapalana government, has named Cabinet of ministers including the Prime Minister, Members of the Commission to Investigate Allegations of Bribery or Corruption, the IGP, Attorney General, members of SLIIT and the Mahapola Higher Education Scholarship Trust Fund as respondents, and asked for issuing of notices to them and most importantly an order directing the Attorney-General to charge and indict Gamini Jayawickrama Perera, Dr. Wickrama Weerasooriya (deceased), Anil Rajakaruna, Prof Lalith R. Gamage and Prof Luxman Rathnayaka, among others.

Wijeyadasa Rajapakshe alleged that though he made a complaint to the CIABOC on February 25, 2019 that the loss caused to SLIIT as a result of the corrupt transaction at that time was about Rs. 23,000,000,000. (Rs. 23 billion), the outfit did nothing except recording statements from him twice.

As the Minister of Justice and of Higher Education, Wijeyadasa Rajapakshe was privy to all the sordid details of what happened at a particular MTF Board of Governors meeting when the Board was coerced into consenting to the divesting of SLIIT from the MTF.

Now, it is in the hands of the Supreme Court. We shall wait with bated breath. But in the meantime, a debate in Parliament is on the offing, which may bring to the public domain what is still not fully revealed.

Considering all of the above, I cannot but disagree with Prof. Gunawardane that the Vice-Chancellor/CEO of SLIIT should be retained in that position. He has apparently compromised himself, having started splendidly well in bringing SLIIT initially up to what it became later. Here was a golden opportunity for MTF and SLIIT to jointly set up a model for public-private partnership in the provision of higher education to an ‘education-hungry’ generation of Sri Lankan youth. But unfortunately, SLIIT has not conducted itself to be above reproach. Greed has, perhaps, taken over the early ideals of treading new paths in establishing a new kind of higher educational institution, as often as it happens in the conduct of most human affairs. In the end, it seems to have gone the same way as did North Colombo Medical College (NCMC) and South Asian Institute of Technology and Management/Medicine (SAITM) – manipulated by vested interests, for different ends, under different circumstances and different political regimes. Hence, my question in the title. Is it a system failure or corporate greed that creates an environment that attempts at private higher education, as in the three cases mentioned above, have failed our expectations? Failed to show that education, even in the hands of the private sector, is not wholly a ‘tradable commodity, but it is also a public good’.

We, the public also would wish, if it is at all possible, to know the answers to the following:

(i) Why has SLIIT not named the ‘company’ to which the SLIIT Board of Directors transferred the assets of SLIIT in 2015?

(ii) Who owns SLIIT now?

(iii) Why is there deliberate secrecy about ‘company’ that owns SLIIT?

(iv) Who are the shareholders of the above ‘company’?

(v) Does the Chancellor or the Vice-Chancellor/CEO or any other member of the Board of Management of SLIIT have any financial interest or any ownership or shareholding of the said unnamed ‘company’?

Until these questions have unambiguous answers, the truth about SLIIT will not be known.

I believe that a Presidential Commission has to be appointed to probe the allegations of a ‘fraudulent’ ‘swindle’ sullied by corruption at the highest levels of the SLIIT management.

State universities and the UGC

Prof R. P. Gunawardane argues that ‘UGC interference’ in State universities has retarded or restrained their growth and development as universities. I fully agree.

He quotes as examples Harvard, Princeton, MIT, Stanford and all ‘Ivy League’ universities in the US and to a lesser extent the British universities, such as Oxford and Cambridge, that are free from the fetters of government control. I believe that we need to look at their origins and the context in which they were established. Oxbridge were established as religious institutions of learning. The origins of Oxford are lost in the mists of time and legend, but the influence of the Christian Church in these two institutions is well-known. Harvard was founded to train clergy as a ‘church in the wilderness’. Hence, we cannot compare our state universities with the hoary traditions and culture that are behind those institutions that have developed through millennia and centuries. As a result, neither their governance structures nor their ethos can be replicated to our contexts.

Having said that, I agree that we need to strive for higher goals and greater futures for our universities. But, having been in the system for four decades, I have many misgivings about the self-governance of our universities. We have not shown that we have the distinct capabilities of ensuring quality and standards of higher education without state overview. I wish it were otherwise. To illustrate this absence of educational as well as fiduciary or financial responsibility and accountability within our universities, let me quote these two examples.

(1) External Degree Programmes: Several state universities conducted external degree programmes. Sri Jayewardenepura, Kelaniya, Peradeniya and Ruhuna universities were prominent amongst them. As I estimate, 15,000 to 35,000 students were registered annually by each of them. Almost all of them, if not all, were degrees in the Arts and Humanities. The monitoring of quality and standards was poor, and often non-existent. Many academic staff of these universities were external lecturers at mushrooming tutories countrywide, that conducted classes. Though they were expected to make a declaration to their respective universities about their involvement as external teaching staff, to avoid conflict of interest when examiners were appointed, this was practised more in the breach. Corruption became rampant. Examiners were correcting over 5,000 answer scripts. I was not surprised that the Minister of Higher Education, S.B. Dissanayake said publicly that ‘examiners throw answer scripts in the air and give marks according to when and where they fall’. He must have had some inside information. One of them told me that he built his three-storey house from the external degree examination payments he received. The Director of the External Examinations Branch was a much sought-after position. And once in, few left willingly. No control was possible due to pressures of vested interests within universities until the UGC stepped in and limited numbers that could be registered for external degrees by a special circular.

(2) Master’s degree, postgraduate diploma and certificate programmes: Though Bachelor’s degrees are non-fee levying, all other programmes conducted by state universities are fee-levying. Such programmes began to mushroom in all state universities. Academic staff delivering lectures and examining answer scripts were paid handsomely. Therefore, such courses began to proliferate. Master’s programmes were the most lucrative. Some professors and senior staff in universities neglected their undergraduate lectures and concentrated on postgraduate lectures. Examinations were delayed and results were not released for months, if not years. Having paid large sums of money, postgraduate students languished without being awarded their degrees. Some newly established universities with a severe dearth of academic staff even to effectively conduct their undergraduate bachelor’s programmes, were commencing and conducting Master’s programmes. Some even commenced such programmes in Colombo in rented premises with minimal involvement of their academics in the teaching programmes. The quality of these Master’s programmes was much in question. Since the situation was going out of control, the UGC had to bring in stricter criteria for universities to establish postgraduate courses. This had to be done by the UGC because the powerful vested interests within the universities overwhelmed any attempt at internal reform. But, even now, the proliferation of Master’s degree programmes in our state universities are a matter of much concern and debate.

The above are just two examples of the lack of educational and fiduciary or financial governance of the state university system in Sri Lanka.

After all, we are currently debating the deficiencies of governance at the highest levels of government. It is my considered view that neither systems nor persons of adequate integrity are in place for us to entrust self-governance to our universities at present. Corruption will become rampant from student selection to awarding of degrees. This is despite a myriad of UGC circulars. What would the playing fields be, without such an independent referee, and if none of those restraints by circulars (rules) were in existence? I may be a pessimist. But I fear to envisage such a scenario.

Retirement age for judges: Innovation and policy

Published

on

I. The Constitutional Context

Independence of the judiciary is, without question, an essential element of a functioning democracy. In recognition of this, ample provision is made in the highest law of our country, the Constitution, to engender an environment in which the courts are able to fulfil their public responsibility with total acceptance.

As part of this protective apparatus, judges of the Supreme Court and the Court of Appeal are assured of security of tenure by the provision that “they shall not be removed except by an order of the President made after an address of Parliament supported by a majority of the total number of members of Parliament, (including those not present), has been presented to the President for such removal on the ground of proved misbehaviour or incapacity”[Article 107(2)]. Since this assurance holds good for the entirety of tenure, it follows that the age of retirement should be defined with certainty. This is done by the Constitution itself by the provision that “the age of retirement of judges of the Supreme Court shall be 65 years and of judges of the Court of Appeal shall be 63 years”[Article 107(5)].

II. A Proposal for Reform

This provision has been in force ever since the commencement of the Constitution. Significant public interest, therefore, has been aroused by the lead story in a newspaper, Anidda of 13 March, that the government is proposing to extend the term of office of judges of the Supreme Court and the Court of Appeal by a period of two years.

This proposal, if indeed it reflects the thinking of the government, is deeply disturbing from the standpoint of policy, and gives rise to grave consequences. The courts operating at the apex of the judicial structure are called upon to do justice between citizens and also between the state and members of the public. It is an indispensable principle governing the administration of justice that not the slightest shadow of doubt should arise in the public mind regarding the absolute objectivity and impartiality with which the courts approach this task.

What is proposed, if the newspaper report is authentic, is to confer on judges of two particular courts, the Supreme Court and the Court of Appeal, a substantial benefit or advantage in the form of extension of their years of service. The question is whether the implications of this initiative are healthy for the administration of justice.

III. Governing Considerations of Policy

What is at stake is a principle intuitively identified as a pillar of justice.

Reflecting firm convictions, the legal antecedents reiterate the established position with remarkable emphasis. The classical exposition of the seminal standard is, of course, the pronouncement by Lord Hewart: “It is not merely of some importance, but is of fundamental importance that justice should not only be done, but should manifestly and undoubtedly be seen to be done”. (Rex v. Sussex Justices, ex parte McCarthy). The underlying principle is that perception is no less important than reality. The mere appearance of partiality has been held to vitiate proceedings: Dissanayake v. Kaleel. In particular, reasonableness of apprehension in the mind of the parties to litigation is critical: Ranjit Thakur v. Union of India, a reasonable likelihood of bias being necessarily fatal (Manak Lal v. Prem Chaud Singhvi).

The overriding factor is unshaken public confidence in the judiciary: State of West Bengal v. Shivananda Pathak. The decision must be “demonstrably” (Saleem Marsoof J.) fair. The Bar Association of Sri Lanka has rightly declared: “The authority of the judiciary ultimately depends on the trust reposed in it by the people, which is sustained only when justice is administered in a visibly fair manner”.

Credibility is paramount in this regard. “Justice has to be seen to be believed” (J.B. Morton). Legality of the outcome is not decisive; process is of equal consequence. Judicial decisions, then, must withstand public scrutiny, not merely legal technicality: Mark Fernando J. in the Jana Ghosha case. Conceived as continuing vitality of natural justice principles, these are integral to justice itself: Samarawickrema J. in Fernando v. Attorney General. Institutional integrity depends on eliminating even the appearance of partiality (Mandal Vikas Nigam Ltd. v. Girja Shankar Pant), and “open justice is the cornerstone of our judicial system”: (Sahara India Real Estate Corporation Ltd. v. SEBI).

IV. Practical Constraints

Apart from these compelling considerations of policy, there are practical aspects which call for serious consideration. The effect of the proposal is that, among all judges operating at different levels in the judicature of Sri Lanka, judges of the Supreme Court and the Court of Appeal only, to the exclusion of all other judges, are singled out as the beneficiaries of the proposal. An inevitable result is that High Court and District Judges and Magistrates will find their avenues of promotion seriously impeded by the unexpected lengthening of the periods of service of currently serving judges in the two apex courts. Consequently, they will be required to retire at a point of time appreciably earlier than they had anticipated to relinquish judicial office because the prospect of promotion to higher courts, entailing higher age limits for retirement, is precipitately withdrawn. Some degree of demotivation, arising from denial of legitimate expectation, is therefore to be expected.

A possible response to this obvious problem is a decision to make the two-year extension applicable to all judicial officers, rather than confining it to judges of the two highest courts. This would solve the problem of disillusionment at lower levels of the judiciary, but other issues, clearly serious in their impact, will naturally arise.

Public service structures, to be equitable and effective, must be founded on principles of non-discrimination in respect of service conditions and related matters. Arbitrary or invidious treatment is destructive of this purpose. In determining the age of retirement of judges of the Supreme Court and the Court of Appeal, some attention has been properly paid to balance and consistency. The age of retirement of a Supreme Court judge is on par with that applicable to university professors and academic staff in the higher education system. They all retire at 65 years. Members of the public service, generally, retire at 60. Medical specialists retire at 63, with the possibility of extension in special circumstances to 65. The age of retirement for High Court Judges is 61, and for Magistrates and District Judges 60. It may be noted that the policy change in 2022 aimed at specifically addressing the issue of uniformity and compatibility.

If, then, an attempt is made to carve out an ad hoc principle strictly limited to judicial officers, not admitting of a self-evident rationale, the question would inevitably arise whether this is fair by other categories of the public service and whether the latter would not entertain a justifiable sense of grievance.

This is not merely a moral or ethical issue relating to motivation and fulfillment within the public service, but it could potentially give rise to critical legal issues. It is certainly arguable that the proposed course of action represents an infringement of the postulate of equality of treatment, and non-discrimination, enshrined in Article 12(1) of the Constitution.

There would, as well, be the awkward situation that this issue, almost certain to be raised, would then have to be adjudicated upon by the Supreme Court, itself the direct and exclusive beneficiary of the impugned measure.

V. Piecemeal Amendment or an Overall Approach?

If innovation on these lines is contemplated, would it not be desirable to take up the issue as part of the new Constitution, which the government has pledged to formulate and enact, rather than as a piecemeal amendment at this moment to the existing Constitution? After all, Chapter XV, dealing with the Judiciary, contains provisions interlinked with other salient features of the Constitution, and an integrated approach would seem preferable.

VI. Conclusion

In sum, then, it is submitted that the proposed change is injurious to the institutional integrity of the judiciary and to the prestige and stature of judges, and that it should not be implemented without full consideration of all the issues involved.

Ranked 134th in Happiness: Rethinking Sri Lanka’s development through happiness, youth wellbeing and resilience

Published

on

In recent years, Sri Lanka has experienced a succession of overlapping challenges that have tested its resilience. Cyclone Ditwah struck Sri Lanka in November last year, significantly disrupting the normal lives of its citizens. The infrastructure damage is much more serious than the tsunami. According to World Bank reports and preliminary estimates, the losses amounted to approximately US$ 4.1 billion, nearly 4 per cent of the country’s Gross Domestic Product. Before taking a break from that, the emerging crisis in the Middle East has once again raised concerns about potential economic repercussions. In particular, those already affected by disasters such as Cyclone Ditwah risk falling “from the frying pan into the fire,” facing multiple hardships simultaneously. Currently, we see fuel prices rising, four-day workweeks, a higher cost of living, increased pressure on household incomes, and a reduction in the overall standard of living for ordinary citizens. It would certainly affect people’s happiness. As human beings, we naturally aspire to live happy and fulfilling lives. At a time when the world is increasingly talking about happiness and wellbeing, the World Happiness Report provides a useful way of looking at how countries are doing. The World Happiness Report discusses global well-being and offers strategies to improve it. The report is produced annually with contributions from the University of Oxford’s Wellbeing Research Centre, Gallup, the UN Sustainable Development Solutions Network, and other stakeholders. There are many variables taken into consideration for the index, including the core measure (Cantril Ladder) and six explanatory variables (GDP per Capita ,Social Support,Healthy Life Expectancy,Freedom to Make Life Choices,Generosity,Perceptions of Corruption), with a final comparison.

According to the recently published World Happiness Report 2026, Sri Lanka ranks 134th out of 147 nations. As per the report, this is the first time that Sri Lanka has suffered such a decline. Sri Lanka currently trails behind most of its South Asian neighbours in the happiness index. The World Happiness Report 2026 attributes Sri Lanka’s low ranking (134th) to a combination of persistent economic struggles, social challenges, and modern pressures on younger generations. The 2026 report specifically noted that excessive social media use is a growing factor contributing to declining life satisfaction among young people globally, including in Sri Lanka. This calls for greater vigilance and careful reflection. These concerns should be examined alongside key observations, particularly in the context of education reforms in Sri Lanka, which must look beyond their immediate scope and engage more meaningfully with the country’s future.

In recent years, a series of events has triggered political upheaval in countries such as Nepal, characterised by widespread protests, government collapse, and the emergence of interim administration. Most reports and news outlets described this as “Gen Z protests.” First, we need to understand what Generation Z is and its key attributes. Born between 1997 and 2012, Generation Z represents the first truly “digital native” generation—raised not just with the internet, but immersed in it. Their lives revolve around digital ecosystems: TikTok sets cultural trends, Instagram fuels discovery, YouTube delivers learning, and WhatsApp sustains peer communities. This constant, feed-driven engagement shapes not only how they consume content but how they think, act, and spend. Tech-savvy and socially aware, Gen Z holds brands to a higher standard. For them, authenticity, transparency, and accountability—especially on environmental and ethical issues—aren’t marketing tools; they’re baseline expectations. We can also observe instances of them becoming unnecessarily arrogant in making quick decisions and becoming tools of some harmful anti-social ideological groups. However, we must understand that any generation should have proper education about certain aspects of the normal world, such as respecting others, listening to others, and living well. More interestingly, a global survey by the McKinsey Health Institute, covering 42,083 people across 26 countries, finds that Gen Z reports poorer mental health than older cohorts and is more likely to perceive social media as harmful.

Youth health behaviour in Sri Lanka reveals growing concerns in mental health and wellbeing. Around 18% of youth (here, school-going adolescents aged 13-17) experience depression, 22.4% feel lonely, and 11.9% struggle with sleep due to worry, with issues rising alongside digital exposure. Suicide-related risks are significant, with notable proportions reporting thoughts, plans, and attempts, particularly among females. Bullying remains a significant concern, particularly among males, with cyberbullying emerging as a notable issue. At the same time, substance use is increasing, including tobacco, smokeless tobacco, and e-cigarettes. These trends highlight the urgent need for targeted interventions to support youth mental health, resilience, and healthier behavioural outcomes in Sri Lanka. We need to create a forum in Sri Lanka to keep young people informed about this. Sri Lanka can designate a date (like April 25th) as a National Youth Empowerment Day to strengthen youth mental health and suicide prevention efforts. This should be supported by a comprehensive, multi-sectoral strategy aligned with basic global guidelines. Key priorities include school-based emotional learning, counselling services, and mental health training for teachers and parents. Strengthening data systems, reducing access to harmful means, and promoting responsible media reporting are essential. Empowering families and communities through awareness and digital tools will ensure this day becomes a meaningful national call to action.

As discussed earlier, Sri Lanka must carefully understand and respond to the challenges arising from its ongoing changes. Sri Lanka should establish an immediate task force comprising responsible stakeholders to engage in discussions on ongoing concerns. Recognising that it is not a comprehensive solution, the World Happiness Index can nevertheless act as an important indicator in guiding a paradigm shift in how we approach education and economic development. For a country seeking to reposition itself globally, Sri Lanka must adopt stronger, more effective strategies across multiple sectors. Building a resilient and prosperous future requires sound policymaking and clear strategic direction.

Hidden diversity in Sri Lanka’s killifish revealed: New study reshapes understanding of island’s freshwater biodiversity

Published

on

Aplocheilus parvus

A groundbreaking new study led by an international team of scientists, including Sri Lankan researcher Tharindu Ranasinghe, has uncovered striking genetic distinctions in two closely related killifish species—reshaping long-standing assumptions about freshwater biodiversity shared between Sri Lanka and India.

Published recently in Zootaxa, the research brings together leading ichthyologists such as Hiranya Sudasinghe, Madhava Meegaskumbura, Neelesh Dahanukar and Rajeev Raghavan, alongside other regional experts, highlighting a growing South Asian collaboration in biodiversity science.

For decades, scientists debated whether Aplocheilus blockii and Aplocheilus parvus were in fact the same species. But the new genetic analysis confirms they are “distinct, reciprocally monophyletic sister species,” providing long-awaited clarity to their taxonomic identity.

Speaking to The Island, Ranasinghe said the findings underscore the hidden complexity of Sri Lanka’s freshwater ecosystems.

“What appears superficially similar can be genetically very different,” he noted. “Our study shows that even widespread, common-looking species can hold deep evolutionary histories that we are only now beginning to understand.”

A tale of two fishes

The study reveals that Aplocheilus blockii is restricted to peninsular India, while Aplocheilus parvus occurs both in southern India and across Sri Lanka’s lowland wetlands.

Despite their close relationship, the two species show clear genetic separation, with a measurable “genetic gap” distinguishing them. Subtle physical differences—such as the pattern of iridescent scales—also help scientists tell them apart.

Co-author Sudasinghe, who has led several landmark studies on Sri Lankan freshwater fishes, noted that such integrative approaches combining genetics and morphology are redefining taxonomy in the region.

Echoes of ancient land bridges

The findings also shed light on the ancient biogeographic links between Sri Lanka and India.

Scientists believe that during periods of low sea levels in the past, the two landmasses were connected by the now-submerged Palk Isthmus, allowing freshwater species to move between them.

Later, rising seas severed this connection, isolating populations and driving genetic divergence.

“These fishes likely dispersed between India and Sri Lanka when the land bridge existed,” Ranasinghe said. “Subsequent isolation has resulted in the patterns of genetic structure we see today.”

Meegaskumbura emphasised that such patterns are increasingly being observed across multiple freshwater fish groups in Sri Lanka, pointing to a shared evolutionary history shaped by geography and climate.

A deeper genetic divide

One of the study’s most striking findings is that Sri Lankan populations of A. parvus are genetically distinct from those in India, with no shared haplotypes between the two regions.

Dahanukar explained that this level of differentiation, despite relatively recent geological separation, highlights how quickly freshwater species can diverge when isolated.

Meanwhile, Raghavan pointed out that these findings reinforce the importance of conserving habitats across both countries, as each region harbours unique genetic diversity.

Implications for conservation

The study carries important implications for conservation, particularly in a country like Sri Lanka where freshwater ecosystems are under increasing pressure from development, pollution, and climate change.

Ranasinghe stressed that understanding genetic diversity is key to protecting species effectively.

“If we treat all populations as identical, we risk losing unique genetic lineages,” he warned. “Conservation planning must recognise these hidden differences.”

Sri Lanka is already recognised as a global biodiversity hotspot, but studies like this suggest that its biological richness may be even greater than previously thought.

A broader scientific shift

The research also contributes to a growing body of work by scientists such as Sudasinghe and Meegaskumbura, challenging traditional assumptions about species distributions in the region.

Earlier studies often assumed that many freshwater fish species were shared uniformly between India and Sri Lanka. However, modern genetic tools are revealing a far more complex picture—one shaped by ancient geography, climatic shifts, and evolutionary processes.

“We are moving from a simplistic view of biodiversity to a much more nuanced understanding,” Ranasinghe said. “And Sri Lanka is proving to be a fascinating natural laboratory for this kind of research.”

Looking ahead

The researchers emphasise that much remains to be explored, with several freshwater fish groups in Sri Lanka still poorly understood at the genetic level.

For Sri Lanka, the message is clear: beneath its rivers, tanks, and wetlands lies a largely untapped reservoir of evolutionary history.

As Ranasinghe puts it:

“Every stream could hold a story of millions of years in the making. We are only just beginning to read them.”
