Lifting glyphosate ban : Facts and Fiction

Published

on

Prof. O.A.Ileperuma

Dr. Ranil Senanayake’s criticism (The Island 22/9/2022) of Dr. Parakrama Waidyanatha’s article which appeared in The Island (19/9/2022) on the lifting of the ban on glyphosate is unfair and does not conform to what is already known. Glyphosate was banned without any scientific basis solely for political reasons. Glyphosate use in Sri Lanka can be traced to 1977, when it was permitted to control weeds on tea plantations. Glyphosate was approved for paddy soils in 1998 but paraquat, which was cheaper, was widely used at that time. When paraquat was phased out by the government in 2014, glyphosate came into regular use. The chronic kidney disease in the North-Central Province had been there long before 2014 and glyphosate absolutely has no role in causing the kidney disease. Furthermore, chronic diseases such as the Rajarata kidney disease manifest only after about 15-20 years of continuous exposure to a toxin. Scientific research has shown that glyphosate undergoes total degradation to harmless glycine and phosphate in the soils in about 7 days. Also, these studies reveal that glyphosate binds strongly to soil and there is less likelihood of it getting leached into the irrigation canals and reservoirs. When applied to paddy fields what is important is whether glyphosate goes into the paddy seeds. It is important to realise that paddy is harvested at least two months after the glyphosate is applied and hence there is no likelihood of the rice seeds getting contaminated.

Dr. Senanayake talks about the biomagnificationm, which is valid not only for glyphosate but also to many other poisons which enter our bodies. An earlier study carried out at the University of Peradeniya revealed the presence of ultratrace levels of pesticides in the drinking waters at Peradeniya. These originate in the widespread use of pesticides in the Nuwara Eliya District. These trace levels of pesticides accumulate in the fatty tissues, a process called bioaccumulation. Human body has a remarkable way to get rid of these poisons; the liver acts as the waste treatment plant and these poisons are detoxified in the liver and excreted through the kidney. However, excessive overloading of our bodies with toxic materials can be detrimental to our health. Dr. Waidyanatha correctly points this out when he says that it is the dose that matters. This in no way justifies excessive use of pesticides in agriculture.

Dr. Senanayake should realise that while organic agriculture practised prior to the 1960s in Sri Lanka was still not sufficient to provide enough rice for its population. The population of Sri Lanka was around 7 million in 1948 and it has increased to about 22 million today. Organic paddy farming can at best provide rice for only about 5 million and even during British rule, rice was imported the country starting from the 1920s. Therefore, agrochemicals are a necessary evil to feed a hungry population. The alternative is to import rice from other countries often having elevated levels of heavy metals such as arsenic and cadmium.

As regards the chronic kidney disease, scientific research has firmly established that fluoride in combination with hard water is what causes it. It is certainly not caused by irrigation waters contrary to Dr. Senanayake’s claim. The absence of the disease from Anuradhapura and Padaviya townships, where people consume water from irrigation tanks clearly, shows that all these agrochemicals ending up in reservoirs play no role in causing the kidney disease. Perhaps, he is referring to a publication by agriculturists at the University Peradeniya, who postulated that there were very high levels of cadmium arising from the agrochemicals washed out from the hill country ending up in Rajarata reservoirs. There is absolutely no evidence to suggest that people who consume irrigation waters are affected by the kidney disease. Several independent researchers have rejected these high cadmium levels because the values for cadmium in water determined at several laboratories in Japan, Germany and Sri Lanka using advanced instrumentation obtained values which are thousand times lower. I am aware of the basic errors in the analytical methods used by these agricultural scientists which led to such high values of cadmium and there is no independent confirmation of these results.

A comprehensive study from the Ginnoruwa area in the Mahaweli Zone C clearly establishes the distinctive role played by fluoride and water hardness causing kidney disease. There are two villages in this area, Sarabhoomi located along the banks of the Mahaweli river and Badulupura located at a higher elevation. While Sarabhoomi has zero kidney patients, Badulupura has over 30% of its adults affected by kidney disease. People in Sarabhoomi consume water from the river itself or from shallow wells located close to the river with low levels of fluoride while Badulupura residents get their water from deep wells which are invariably rich in fluoride and hardness. Hence the argument that irrigation water contaminated with the agricultural runoffs from the hill country causes the kidney disease does not explain why Sarabhoomi residents are not affected by this disease.

I have worked on the Rajarata kidney disease from 2003, when it first came to the limelight and visited most of the areas affected and all kidney patients have consumed fluoride rich water without exception. Most of these patients come from areas far away from any major reservoirs. As a result, they had to dig wells in the remote areas and these invariably reach the bed rock and fluoride leaching from the rocks resulted in the excessive fluoride in these wells. In the ancient agricultural civilisations of Sri Lanka, people lived close to the main reservoirs or its canals and used water from these sources and these invariably had low fluoride levels. However, with the colonisation schemes starting from the 1950s people were provided with lands far away from these reservoirs and they had to dig deep wells to provide them with water. This is the reason why this disease is of relatively recent origin.

In one study from Chettikulam, people are affected not only by the kidney disease but also skeletal fluorosis. The provision of purified water to this area resulted in a considerable reduction of progression of the disease and people who could not even stand up are now doing their previous professions. One patient who was asked undergo a kidney transplant is now able to carry out his farming activities and the doctors have now declared that a transplant is no longer necessary. All these people use water from deep wells and there are no irrigation canals nearby. It is patently clear that the high fluoride levels in their drinking water has caused the disease.

One has to be practical in promoting the popular slogan of toxin free agriculture. Decades of dedicated research by our agricultural scientists have resulted in self-sufficiency in rice. Banning agrochemicals will have a disastrous effect on agricultural productivity. We already see the ill effects of the unwise decision to ban agrochemicals in 2019 which has resulted in severe food shortages and escalating prices of agricultural produce. Public should not be misled by fanciful theories of organic agriculture which only help to create unwarranted and unfounded information about kidney disease and other health effects of agrochemicals and glyphosate.

University admission crisis: Academics must lead the way

Published

on

130,000 students are left out each year—academics hold the key

Each year, Sri Lanka’s G.C.E. Advanced Level examination produces a wave of hope—this year, nearly 175,000 students qualified for university entrance. Yet only 45,000 will be admitted to state universities. That leaves more than 130,000 young people stranded—qualified, ambitious, but excluded. This is not just a statistic; it is a national crisis. And while policymakers debate infrastructure and funding, the country’s academics must step forward as catalysts of change.

Beyond the Numbers: A National Responsibility

Education is the backbone of Sri Lanka’s development. Denying access to tens of thousands of qualified students risks wasting talent, fueling inequality, and undermining national progress. The gap is not simply about seats in lecture halls—it is about the future of a generation. Academics, as custodians of knowledge, cannot remain passive observers. They must reimagine the delivery of higher education to ensure opportunity is not a privilege for the few.

Expanding Pathways, Not Just Campuses

The traditional model of four-year degrees in brick-and-mortar universities cannot absorb the demand. Academics can design short-term diplomas and certificate programmes that provide immediate access to learning. These programmes, focused on employable skills, would allow thousands to continue their education while easing pressure on degree programmes. Equally important is the digital transformation of education. Online and blended learning modules can extend access to rural students, breaking the monopoly of physical campuses. With academic leadership, Sri Lanka can build a reliable system of credit transfers, enabling students to begin their studies at affiliated institutions and later transfer to state universities.

Partnerships That Protect Quality

Private universities and vocational institutes already absorb many students who miss out on state admissions. But concerns about quality and recognition persist. Academics can bridge this divide by providing quality assurance and standardised curricula, supervising joint degree programmes, and expanding the Open University system. These partnerships would ensure that students outside the state system receive affordable, credible, and internationally recognised education.

Research and Advocacy: Shaping Policy

Academics are not only teachers—they are researchers and thought leaders. By conducting labour market studies, they can align higher education expansion with employability. Evidence-based recommendations to the University Grants Commission (UGC) can guide strategic intake increases, regional university expansion, and government investment in digital infrastructure. In this way, academics can ensure reforms are not reactive, but visionary.

Industry Engagement: Learning Beyond the Classroom

Sri Lanka’s universities must become entrepreneurship hubs and innovation labs. Academics can design programmes that connect students directly with industries, offering internship-based learning and applied research opportunities. This approach reduces reliance on classroom capacity while equipping students with practical skills. It also reframes education as a partnership between universities and the economy, rather than a closed system.

Making the Most of What We Have

Even within existing constraints, academics can expand capacity. Training junior lecturers and adjunct faculty, sharing facilities across universities, and building international collaborations for joint programmes and scholarships are practical steps. These measures maximise resources while opening new avenues for students.

A Call to Action

Sri Lanka’s university admission crisis is not just about numbers—it is about fairness, opportunity, and national development. Academics must lead the way in transforming exclusion into empowerment. By expanding pathways, strengthening partnerships, advocating for policy reform, engaging with industry, and optimizing resources, they can ensure that qualified students are not left behind.

Post-Easter Sri Lanka: Between memory, narrative, and National security

Published

on

As Sri Lanka approaches the seventh commemoration of the Easter Sunday attacks, the national mood is once again marked by grief, reflection, and an enduring sense of incompleteness. Nearly seven years later, the tragedy continues to cast a long shadow not only over the victims and their families, but over the institutions and narratives that have since emerged.

Commemoration, however, must go beyond ritual. It must be anchored in clarity, accountability, and restraint. What is increasingly evident in the post-Easter landscape is not merely a search for truth, but a contest over how that truth is framed, interpreted, and presented to the public.

In recent times, public discourse has been shaped by book launches, panel discussions, and media interventions that claim to offer new insights into the attacks. While such contributions are not inherently problematic, the manner in which certain narratives are advanced raises legitimate concerns. The selective disclosure of information particularly when it touches on intelligence operations demands careful scrutiny.

Sri Lanka’s legal and institutional framework is clear on the sensitivity of such matters. The Official Secrets Act (No. 32 of 1955) places strict obligations on the handling of information related to national security. Similarly, the Police Ordinance and internal administrative regulations governing intelligence units emphasize confidentiality, chain of command, and the responsible use of information. These are not mere formalities; they exist to safeguard both operational integrity and national interest.

When individual particularly those with prior access to intelligence structures enter the public domain with claims that are not subject to verification, it raises critical questions. Are these disclosures contributing to justice and accountability, or are they inadvertently compromising institutional credibility and future operational capacity?

The challenge lies in distinguishing between constructive transparency and selective exposure.

The Presidential Commission of Inquiry into the Easter Sunday Attacks provided one of the most comprehensive official examinations of the attacks. Its findings highlighted a complex web of failures: lapses in intelligence sharing, breakdowns in inter-agency coordination, and serious deficiencies in political oversight. Importantly, it underscored that the attacks were not the result of a single point of failure, but a systemic collapse across multiple levels of governance.

Yet, despite the existence of such detailed institutional findings, public discourse often gravitates toward simplified narratives. There is a tendency to identify singular “masterminds” or to attribute responsibility in ways that align with prevailing political or ideological positions. While such narratives may be compelling, they risk obscuring the deeper structural issues that enabled the attacks to occur.

Equally significant is the broader socio-political context in which these narratives are unfolding. Sri Lanka today remains a society marked by fragile intercommunal relations. The aftermath of the Easter attacks saw heightened suspicion, polarisation, and, in some instances, collective blame directed at entire communities. Although there have been efforts toward reconciliation, these fault lines have not entirely disappeared.

In this environment, the language and tone of public discourse carry immense weight. The framing of terrorism whether as a localized phenomenon or as part of a broader ideological construct must be handled with precision and responsibility. Overgeneralization or the uncritical use of labels can have far-reaching consequences, including the marginalization of communities and the erosion of social cohesion.

At the same time, it is essential to acknowledge that the global discourse on terrorism is itself contested. Competing narratives, geopolitical interests, and selective historiography often shape how events are interpreted. For Sri Lanka, the challenge is to avoid becoming a passive recipient of external frameworks that may not fully reflect its own realities.

A professional and unbiased approach requires a commitment to evidence-based analysis. This includes:

· Engaging with primary sources, including official reports and judicial findings
·

· Cross-referencing claims with verifiable data
·

· Recognizing the limits of publicly available information, particularly in intelligence matters

It also requires intellectual discipline the willingness to question assumptions, to resist convenient conclusions, and to remain open to complexity.

The role of former officials and subject-matter experts in this discourse is particularly important. Their experience can provide valuable insights, but it also carries a responsibility. Public interventions must be guided by professional ethics, respect for institutional boundaries, and an awareness of the potential impact on national security.

There is a fine balance to be maintained. On one hand, democratic societies require transparency and accountability. On the other, the premature or uncontextualized release of sensitive information can undermine the very systems that are meant to protect the public.

As Sri Lanka reflects on the events of April 2019, it must resist the temptation to reduce a national tragedy into competing narratives or political instruments. The pursuit of truth must be methodical, inclusive, and grounded in law.

Easter is not only a moment of remembrance. It is a test of institutional maturity and societal resilience.

The real question is not whether new narratives will emerge they inevitably will. The question is whether Sri Lanka has the capacity to engage with them critically, responsibly, and in a manner that strengthens, rather than weakens, the foundations of its national security and social harmony.

In the end, justice is not served by noise or conjecture. It is served by patience, rigor, and an unwavering commitment to truth.

Need to consult, compromise and reach optimal common ground on critical issues of national interest

Published

on

Delivering the keynote address at the 54th Memorial of the late Minister Philip Gunawardena, former Foreign Secretary HMGS Palihakkara, called for a culture of consensus on key public policy issues in the country as the way forward from recovery to sustainable growth in a world of deepening violence and diminishing cooperation.

Excerpts.

Today, we gather to honour and remember the late Hon. Philip Gunawardena—virtually a household name to my generation, fondly known to the ordinary folks just as Philip ‘Mathithuma’- a leader whose life was woven into the very fabric of Sri Lanka’s struggle for justice, dignity, and independence.

Philip Gunawardena was not merely a political leader; he was a visionary, a reformer, and a fearless voice for the common people. While he was an iconic figure and a staunch socialist, he remained a pragmatic modernist as well. This, obviously, is quite a complex and difficult political binary to maintain. As history has it, he did acquit himself doing it. At a time when speaking truth to power demanded immense courage, he stood unwavering. He believed deeply that a nation’s strength lies not in privilege, but in equality—in uplifting farmers, workers, and the forgotten voices of society. The famous Paddy Land Act and the concept of Apex Cooperative Bank which later transformed into the present-day Peoples Bank and many other public policy and institutional creations are emblematic of his deep knowledge of the economic challenges and his holistic approach to development.

On the other hand, others saw Philip demonstrating hard-nosed pragmatism, not a naïve ideological bent.

Dr. Sarath Amunugama, a friend and a public servant turned politician said of Philip:

“On Socialism itself Philip had a different perspective – You talk of Socialism. You cannot socialise poverty. You can only socialise plenty. And if people cannot work, if they cannot produce, you cannot have Socialism.” *

The volume being launched today contains Philip Gunawardena’s speeches and initiatives, documents in great detail the drive and substance he deployed to deliver social justice and economic outcomes to those working classes.

He was aptly called the “Father of Socialism” in Sri Lanka, even lionised as the Boralugoda Sinhaya. But titles and appellations alone cannot capture the spirit of the man. People were captivated not only by the inimitable force of his articulation and commitment but perhaps equally or even more, by substance and cogency of his argument.

He was a bridge between the ideal and the actionable.

In my official work overlap with his capacity as the Minister of Industries in the 1960s, I personally experienced Minister Philip’s ability to refurbish concepts in relation to ground realities. His work in land reform and his commitment to social justice were not abstract ideas—they were real, tangible efforts to improve lives and reshape the nation’s future. The analysis Philip presented and prescriptions he passionately advocated, in both legislative and policy realms, are touched upon in good detail here in this book being launched today. I must say it is a trove for a researcher.

Beyond his public life, Philip Gunawardena was a man of conviction and principle. He carried with him a profound sense of responsibility to his people, and he never wavered from his beliefs, even when it came at great personal cost. That is a legacy not easily measured, but deeply felt.

Today, as we reflect on his life, we are reminded that true leadership is not about power, but about purpose. It is about working tirelessly for the greater good of the Nation State and its people while standing firm in one’s values

Philip’s words -more importantly his deed- brought into sharp relief a truism prevalent in divisive politics

esp. here in Sri Lanka. It is that while blinkered politicians build opinions, only true leaders can build consensus. The former does it for parochial transactional gain the latter does it for strategic and sustainable national gain.

Philip of course was emblematic of the latter.

The decision by Philip to join the ‘National Govt’ of Dudley Senanayake was a much debated but little understood affair. – Optics were basically reduced to a celebrated Socialist icon joining a gentle Capitalist to form a

National Government. It was inevitably a controversial move. Equally, it was also a bold manifestation of that consensus building spirit. More so because his decision was predicated on his unwavering support for a fundamental human right- the freedom of expression, and opposition to nationalisation of the free press- a fundamental tenet of the democratic-socialist binary. Leave aside the unfinished or open-ended debate about democracy or socialism. Philip was signalling that consensual statecraft is the way forward for the nation’s progress and prosperity of its people. The motto was that what is best ideologically should not stand in the way of what is consensually good for the nation and the common man. When Philip famously said that I will work with the ‘Devil or even his grandmother if that brings about common good’, he in a way articulated the inherent quality of consensus on key public policy matters like the press freedom and other foundational things.

That certainly is the interpretation in my Book!

Consensus is not about making any or all contending parties absolutely happy about the issue at hand- it is about dispensing managed unhappiness among all parties in order to advance a common cause benefitting the people at large. It is the ‘equitable distribution of reasonable unhappiness’ among all parties concerned. When that occurs, consensus happens. It is the most potent algorithm to produce win-win solutions in human relations within or among states.

This is a great lesson in statecraft and public policy making for present day politicians in our country who seem to quarrel like street vendors on a rainy day, on all issues. They have thus reduced the grave responsibility of democratic governance to a trivial zero-sum formula of the Government proposing and the Opposition opposing most of the time- if not all the time! They are either unable or unwilling to explore and reach a consensual middle ground to advance the national interests on a host of public policy issues ranging from economic reforms, security and foreign policies, the rule of law, accountability, reconciliation and so on.

All issues are thus a game for the govt toppling game.

This is a lesson for some of the current crop of politicians in this country who easily conflate polemics with substance and verbiage with eloquence.

All this ignores the national interest of building consensus as opposed to building polarisation for vote winning.

May I express the hope that all of us, especially those involved in that dreadful art form called politics in this country, revisit the thought processes of Philip Gunawardena documented in this volume to understand that compromise and consensus is possible in this country- especially on key public policy issues that profoundly touch our fundamental national interests.

Speaking of a culture of consensus the likes of Philip Gunawardena advocated in eloquent words and courageous deeds more than half a century ago, let me conclude with a brief comment on their relevance and resonance with the inventory of sri Lanka’s foreign policy and diplomacy challenges.

We all know that Sri Lanka’s overriding national priority in recent times was and remains the process of recovery from a crippling economic crisis and dovetailing it into a sustainable growth pathway. For this we must carefully prepare ourselves to prudently navigate the critical gauntlet of 2028 when we have to resume debt repayment- a challenge looming larger and larger every single day. Especially so in a world convulsed by violent conflict and economic and financial disruption like what is unfolding in West Asia right now. The violent spiral that has peaked there now will impact our foreign relations and recovery effort in most profound ways. If one is serious about making our recovery and growth stable and sustainable in this volatility, it must therefore be firmly anchored in a domestic political consensus on economic reform and foreign policy framework that is programmed towards three things:

– first, liberate the indispensable economic reforms from the destructive politics of government toppling,

– second, insulate us from the adversities of the ongoing geopolitical violence,

-third, guide us towards securing opportunities for our economic interests in this evolving geopolitical vortex.

Of course, the ‘prime-mover’ responsibility of this common ground building process lies with the government which has an unprecedented and strong voter’ mandate to do it. It must therefore stop acting as if it is still in an election campaign mode and must take cognizance of the fact that they are governing now. The Opposition must understand too that their job is not to oppose everything that the govt proposes and that they are the ‘shadow govt.,’ in the best traditions of parliamentary democracy. They must therefore stop acting like a shadow of the Opposition bent on Govt toppling game 24/7 but behave like a true ‘shadow government’ promoting consensus until the voters in due course do the regime change, when necessary.

Both sides should therefore consult, compromise and reach optimal common ground on critical issues of vital national interest. If our politicians don’t embrace a culture of consensus on such public policy issues of foundational importance, yet another crisis will embrace us in due course, perhaps sooner than they expect. Templates of statesmanship provided by the likes of Philip to reach consensual grounds through informed and timely compromises shedding ideological or parochial interests, might come in handy here.
