It appears that President Ranil Wickremasinghe, all along his political career, has acted in the belief that he can bring about national unity, true national reconciliation among different communities and find a lasting solution to the ethnic problem only by granting more and more concessions to the racist political parties with separatist agendas in the North and the East and complying with their demands.

In 2002, as the Prime Minister, Wickremesinghe signed, without the approval of President Chandrika Kumaratunga, an Oslo-brokered ceasefire agreement with the LTTE, allowing the LTTE to have internal self-administration in the areas under their control in the North-East. In 2005, he supported the move of the Kumaratunga government to sign a Memorandum of Understanding with the LTTE for the establishment of a Post-Tsunami Operational Management Structure (P-TOMS Agreement) under LTTE leadership for carrying out reconstruction work in the six Tsunami affected Districts in the North-East. In 2006, he assured the TNA of support for the re-merger of Northern and Eastern Provinces if a motion was brought for that purpose in Parliament. During the war for the liberation of the North-East from terrorism, instead of supporting the war effort, his party tried to derail the war effort by abstaining from voting for the extension of the Emergency and making derogatory remarks about the victories of the armed forces.

Common Dream of Wickremasinghe and Sampanthan

In his Address to Parliament on February 8, 2023 delivering the Policy Statement of the Government, President Wickremasinghe disclosed a common dream Mr. Sampanthan and he had been trying to realise over the years thus:

‘‘Both Hon. R. Sampanthan and I were elected to Parliament in 1977. We both have a common dream, which is to provide a sustainable solution to the ethnic problem in Sri Lanka while we are both in Parliament. Ever since, we have been discussing that dream and have been making efforts towards its achievement. All previous attempts have failed, but we wish to succeed this time. We expect your support to this end.’’

Before proceeding to examine the dream of the President, let us examine the dream of Sampanthan and the political organisations led by him: the Tamil United Liberation Front (TULF) and the Tamil National Alliance (TNA). This dream remained continuously unchanged since the founding of the Ilankai Thamil Arasu Katchi (Federal Party) in 1949. The name of the Party – Ilankai Thamil Arasu Katchi (ITAK) or (Tamil State Party of Ceylon) itself reflects this dream. This dream was reiterated in various resolutions passed at their conferences and public declarations at different times.

Dream of Sampanthan and other Tamil leaders

Trincomalee Resolution of ITAK – April 1957

The Resolution passed at the first National Convention of the ITAK held in Trincomalee in April 1957 elaborates on this dream citing the components this dream consists of:

“Inasmuch as it is the inalienable right of every nation to enjoy full political freedom without which its spiritual, cultural and moral stature must degenerate and inasmuch as the Tamil Speaking People in Ceylon constitute a nation distinct from that of the Sinhalese by every fundamental test of nationhood, firstly that of a separate historical part in this island at least as ancient and as glorious as that of the Sinhalese, secondly by the fact of their being a linguistic entity different from that of the Sinhalese, with an unsurpassed classical heritage and a modern development of language which makes Tamil fully adequate for all present day needs and finally by reason of their traditional habitation of definite areas which constitute one-third of this island, the first National Convention of the I.T.A.K. demands for the Tamil Speaking Nation their inalienable right to political autonomy and calls for a plebiscite to determine the boundaries of the linguistic states in consonance with the fundamental and unchallengeable principle of self-determination.”

The components of this dream are as follows:

a

. Tamil Speaking People in Ceylon constitute a nation distinct from that of the Sinhalese by every fundamental test of nationhood: i. playing a separate historical part in this island at least as ancient and as glorious as that of the Sinhalese; ii. with an unsurpassed classical heritage and a modern development of language making Tamil fully adequate for all present-day needs; iii. their traditional habitation of definite areas constituting one-third of this island; b. Inalienable right of the Tamil Speaking Nation to political autonomy.

Vaddukoddai Resolution of TULF

The Vaddukoddai Resolution unanimously adopted on 16 May 1976 by the Tamil United Liberation Front (TULF) consisting of all the Tamil political parties and groups in the North – East narrated in its preamble all the rights denied to or deprived of Tamil people by the successive Sinhala governments and their demands for restoration thereof:

a. The Tamils of Ceylon by virtue of their language, their religions, their separate culture and heritage, their history of independent existence as a separate state over a distinct territory for several centuries and, above all by their will to exist as a separate entity ruling themselves in their own territory, are a nation distinct and apart from Sinhalese;

b. Throughout centuries from the dawn of history, the Sinhalese and Tamil nations have divided between themselves the possession of Ceylon, the Sinhalese inhabiting the interior of the country in its Southern and Western parts and the Tamils possessing the Northern and Eastern districts;

c. Successive Sinhalese governments since independence have encouraged and fostered the aggressive nationalism of the Sinhalese people and have used their political power to the detriment of the Tamils by making serious inroads into the territories of the former Tamil Kingdom by a system of planned and state-aided Sinhalese colonization and large scale regularization of recently encouraged Sinhalese encroachments, calculated to make the Tamils a minority in their own homeland.

d. The proposals submitted to the Constituent Assembly by the Ilankai Thamil Arasu Katchi for maintaining the unity of the country while preserving the integrity of the Tamil people by the establishment of an autonomous Tamil State within the framework of a Federal Republic of Ceylon.

‘‘This convention resolves that restoration and reconstitution of the Free, Sovereign, Secular, Socialist State of TAMIL EELAM, based on the right of self-determination inherent to every nation, has become inevitable in order to safeguard the very existence of the Tamil Nation in this Country.

‘‘

This Convention directs the Action Committee of the Tamil United Liberation Front to formulate a plan of action and launch without undue delay the struggle for winning the sovereignty and freedom of the Tamil Nation; and

‘‘

Chelvanayagam

This Convention calls upon the Tamil Nation in general and the Tamil youth in particular to come forward to throw themselves fully into the sacred fight for freedom and to flinch not till the goal of a sovereign state of TAMIL EELAM is reached.’’

· From this it clearly appears that not only the LTTE and the other armed militant groups, but the entire leadership of the TULF was also responsible for aiding and abetting and leading the Tamil youth for the 30-year war against Sri Lanka.

Although the LTTE was defeated and the 30-year war came to an end on May 18, 2009, the ITAK, the TULF or the TNA and the other political parties in the North-East have not abandoned their goal or dream of creating a separate Tamil State in the amalgamated Northern and Eastern Provinces of Sri Lanka. They have only changed their strategy and tactics in the march for reaching their goal.

Speech made by R. Sampanthan, the leader of the TULF, at the 14th ITAK Convention held in Batticaloa in May 2012

In this speech, Sampanthan clearly explains to their members their new strategy to achieve their goal of a separate state thus:

“We gather here following our victory in the passage of the recent Resolution at the UN Human Rights Council, a condemnation against the SL government by the international community.

“Ilankai Thamil Arasu Katchi was created by S. J. V. Chelvanayagam, the father of Tamil Nation, for the purpose of establishing self-determination of the Tamil people on this island. This objective is evident in both the name of the party and in the manner in which it operates.

“Tamil United Liberation Front, of which our party was a member, took the historical decision to establish the separate government of Tamil Eelam in 1976. Based on this decision of our party, and the need to place ourselves in a position of strength, Tamil youth decided to oppose violence with violence and began to rise up as armed rebel groups.

“Liberation Tigers of Tamil Eelam, became a great force within the Tamil community.

“We remember the Tamil youth who sacrificed their lives in armed struggle. …. SL government has committed the crime of extermination against our people,

“The intervention of India has clearly taught us the lesson that whatever our aspirations may be, India will never welcome a political solution in Sri Lanka that does not accord with the interests of India.

“Achieving Tamil Eelam was becoming an increasingly unrealistic goal. Thus, instead of sacrificing more lives to this cause, our party with the help of India, began supporting a solution that allowed Tamil people to live within a united Sri Lanka.

“A most important lesson we have learnt from the past 60 years… is that we should act strategically, with the awareness that global powers will act based on their domestic interests.

“Further, a struggle that runs counter to the international community, built only on military might, will not prevail. It is for this reason, that in the new environment created by various global influences, we have, together with the support and assistance of the international community, found new ways of continuing with our struggle.

“Our expectation of a solution to the ethnic problem of the sovereignty of the Tamil people is based on a political structure outside that of a unitary government, in a united Sri Lanka in which Tamil people have all the powers of government needed to live with self-respect and self-sufficiency.

“The position that the North and East of Sri Lanka are the areas of historical habitation of the Tamil speaking people cannot be compromised in this structure of government…. We must have unrestricted authority to govern our land, protect our own people, and develop our own economy, culture and tradition… Meaningful devolution should go beyond the 13th Amendment to the Constitution passed in 1987.

“The above solution is one that is likely to be acceptable to members of the international community including India and the United States.

“Any solution to the ethnic problem concerning the sovereignty of the Tamil people must be acceptable to the Muslim community in Sri Lanka.

“The international practice prevalent during the mid-eighties, when the intervention of India occurred, has now changed. Although the issue at hand is the same, the prevailing conditions are different. The struggle is the same, but the approaches we employ are different. Our aim is the same, but our strategies are different. The players are the same, but the alliances are different. That is the nature of the Tamil people. Although we still have the same aim, the methods we use now are different.

“The current practices of the international community may give us an opportunity to achieve, without the loss of life, the soaring aspirations we were unable to achieve by armed force.’’.’’  www.sangam.org/2012/06/Sampanthan_Speech.php

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.”
