Lifting glyphosate ban : Facts and Fiction
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.

Can a punishment-free child become a threat to Sri Lankan society?
Children are the future of every nation, and the values they learn during childhood shape the society they will eventually lead. In Sri Lanka, where family traditions, respect for elders, and social responsibility have long been important cultural values, the way children are raised remains a topic of great interest. In recent years, many parents and educators have moved away from traditional forms of punishment and embraced more child-friendly approaches to discipline. While protecting children from physical and emotional harm is essential, an important question arises: can a child who grows up without any form of punishment or consequences become a threat to Sri Lankan society?
To answer this question, it is necessary to understand the difference between punishment and discipline. Punishment is often associated with penalties imposed for wrongdoing, while discipline refers to teaching children self-control, responsibility, and respect for rules. Modern child psychology generally discourages harsh physical punishment because it can cause fear, anxiety, and resentment. However, completely removing consequences for inappropriate behavior may create a different set of problems.
Sri Lankan society has traditionally emphasized discipline within the family. Parents, grandparents, and teachers have often played active roles in guiding children’s behavior. Respect for elders, obedience, and good manners have been considered important virtues. While some traditional disciplinary methods may no longer be acceptable, the underlying principle of teaching accountability remains relevant.
A child who never faces consequences for wrongdoing may struggle to understand the boundaries that exist in society. For example, if a child is allowed to insult others, damage property, or ignore rules without correction, they may develop the belief that their actions have no consequences. Such attitudes can become problematic when the child enters school, the workplace, or the wider community.
Sri Lankan schools already face challenges related to student discipline. Teachers often report difficulties in managing classrooms where some students refuse to follow instructions or respect school regulations. When children are not taught accountability at home, educational institutions may find it harder to maintain a productive learning environment. This can affect not only the individual student but also classmates whose education is disrupted.
Another concern is the development of entitlement. A child who is never told “no” may come to believe that personal desires should always be fulfilled. In a society where cooperation and mutual respect are essential, such attitudes can lead to conflicts with peers, teachers, employers, and even family members. Sri Lanka’s social fabric depends heavily on community relationships, and individuals who fail to respect others can weaken these bonds.
The influence of social media and modern technology has added another dimension to this issue. Today’s children have access to information and entertainment on an unprecedented scale. Without proper guidance and consequences, some may misuse technology, engage in cyberbullying, spread misinformation, or develop unhealthy habits. Parents who avoid setting limits may unintentionally expose children to risks that affect both personal development and social well-being.
The workplace offers another example of why accountability is important. Sri Lanka’s economic development depends on a workforce that is disciplined, responsible, and capable of working with others. Employers value punctuality, respect, and professionalism. Individuals who grow up without learning responsibility may find it difficult to meet these expectations, affecting both their personal success and the productivity of organizations.
However, it is equally important not to interpret this argument as support for harsh punishment. Research has shown that excessive physical or emotional punishment can have serious negative effects on children. Fear-based parenting may produce obedience in the short term but can damage confidence, trust, and mental health in the long term. Therefore, the solution is not stricter punishment but more effective discipline.
Positive discipline provides a balanced alternative. It involves setting clear rules, explaining expectations, and applying fair consequences when those rules are broken. For instance, if a child neglects schoolwork, they may lose certain privileges until responsibilities are fulfilled. If they damage property, they can be required to help repair or replace it. Such consequences teach accountability while preserving the child’s dignity.
Sri Lankan parents, teachers, and community leaders all have a role to play in nurturing responsible citizens. Families should create environments where children feel loved and supported but also understand that actions have consequences. Schools should encourage character development alongside academic achievement. Religious and community organizations can reinforce values such as honesty, compassion, and respect for others.
A balanced approach is especially important in a rapidly changing society. As Sri Lanka continues to modernize and integrate with the global community, young people must learn not only their rights but also their responsibilities. Freedom without responsibility can lead to selfishness, while discipline without compassion can lead to fear. The challenge is to find the middle ground.
A punishment-free child can become a concern for Sri Lankan society if the absence of punishment also means the absence of discipline and accountability. Children who never learn consequences may struggle to respect rules, authority, and the rights of others. However, harsh punishment is not the answer. The most effective approach combines love, guidance, clear boundaries, and fair consequences. By raising children who understand both freedom and responsibility, Sri Lanka can build a future generation that strengthens society rather than threatens it.

SriLankan Airbus struck by lightning
On Friday 12 June, 2026, a SriLankan Airlines Airbus 330 was en route from Colombo to Sydney, Australia was about 45 minutes into its flight when a loud bang was heard, accompanied by a blinding flash. In what was assumed to be a lightning strike, the airplane’s left (No. 1) engine was damaged, forcing the aircraft to return to BIA-Katunayake, where it landed safely.
Lightning travels from cloud to cloud or cloud to ground. Because the aircraft is not electrically ‘grounded’, or ‘earthed’, it must have been in the path of the thunder bolt purely by chance. There is also a phenomenon whereby the aircraft may travel through an electrically charged atmosphere (for example a cloud) where an electrical charge could build up and strike, or be emitted, as lightning. In such an instance, pilots hear electrical static in their headsets before the strike. Usually, when lightning strikes an aircraft in flight, the electrical charges remain on the outside, as on a ‘Faraday’s Cage’ apparatus, and the passengers and crew are perfectly safe.
To help the efficient and safe discharge of static electricity from the airplane’s structure, static wicks, or static dischargers, are fitted at the trailing (rearmost) edges of the wings and tail surfaces. When an airplane has landed after a lightning strike, ground engineers count the number of wicks that may have been burnt out to ensure that a minimum (recommended) number is available for a subsequent flight. Sometimes, there is minor damage, like pitting of the paintwork at the points where the charges left the aircraft.
The last instance in the USA of an airplane believed to have been lost due to a lightning strike was on December 8, 1963, when a Pan Am Boeing 707-121, en route from Baltimore, Maryland to Philadelphia, Pennsylvania, suffered a fuel tank explosion, later determined to have been the result of a lightning strike. Since then, aircraft have been rendered immune from lightning damage thanks to extensive research conducted by manufacturers using high-voltage currents.
Interestingly, modern airliners have electronic instrument displays which don’t even flicker when the aircraft is struck by lightning. By a process of connecting all the metallic parts, known as ‘bonding’, the entire fuselage effectively becomes a protective cocoon, so electrical charges caused by lightning will always reside on the outside of the aircraft.
What is unusual in the recent SriLankan Airlines incident is the extent of damage to the left engine. Did it encounter hail or ingest something?
Only a thorough, independent inquiry by aviation safety investigators will reveal the cause.

Beyond diagnosis: A strategic design for 7% growth by 2029 (Part I)
“Vision without execution is hallucination.” – Thomas Edison
Introduction: Stabilisation Is Not Transformation
Sri Lanka has come a long way since the economic collapse of 2022. Inflation has been brought under control. Foreign reserves have improved. Debt restructuring has advanced. Government revenue has increased significantly through taxation reforms. The exchange rate has stabilised, and confidence has gradually returned to financial markets.
These achievements deserve recognition.
However, stabilisation should not be confused with economic transformation. A patient discharged from intensive care is not necessarily healthy. Likewise, an economy that has escaped collapse has not necessarily achieved sustainable prosperity.
The central economic question facing Sri Lanka today is no longer how to avoid another crisis. Rather, it is how to achieve sustained economic growth of at least 7% per annum by 2029.
Unfortunately, much of the current policy debate remains trapped in economic diagnosis. Policymakers, economists, and commentators repeatedly identify familiar problems: (i) low productivity, (ii) weak exports, i(iii) Inadequate innovation, (iv) poor competitiveness, and (v) insufficient investment. While these diagnoses are correct, they are not new.
Sri Lanka now needs economic engineering.
The country requires a clear, measurable, and actionable National Growth Strategy for 2026-2029 that identifies (i) where growth will come from,(ii) what investments are required,(iii) which institutions will lead implementation, and (iv) how success will be measured.
The difference between diagnosis and engineering is the difference between describing a problem and solving it.
The Missing National Growth Target
One of the most striking weaknesses in Sri Lanka’s economic discourse is the absence of a publicly articulated growth target supported by a detailed implementation framework.
Successful economies establish measurable objectives.
Sri Lanka should adopt the following growth trajectory:
2026 – 4%
2027 – 5%
2028 – 6%
2029 – 7%
Such targets would provide direction to investors, public institutions, universities, exporters, and development partners. Without a destination, even the best policies risk becoming disconnected initiatives.
Today, many policy interventions appear fragmented—valuable in isolation but lacking integration into a broader national growth framework.
Growth Will Not Come From Consumption
For decades Sri Lanka relied heavily on consumption, imports, remittances, tourism, and external borrowing.
That model has reached its limits.
No country has achieved sustained prosperity through consumption-led growth alone.
The countries that transformed themselves—Singapore, South Korea, Ireland, Vietnam, and China—generated growth through productive investment, exports, industrialisation, and integration into global markets.
Sri Lanka’s future growth must therefore be driven by investment and exports rather than domestic consumption.
The challenge is not increasing spending but increasing productive capacity.
Export-Led Growth: The First Pillar of Transformation
Every successful Asian growth story has one characteristic in common: exports.
Exports generate foreign exchange, create jobs, attract investment, encourage innovation, and improve productivity.
Sri Lanka should establish an ambitious target of doubling export earnings within the next decade.
This requires moving beyond traditional exports and expanding into:
High-value agriculture
Food processing
Information technology services
Logistics services
Advanced manufacturing
Professional services
Export growth must become a national mission comparable to post-war reconstruction efforts seen elsewhere in Asia.
Without a major expansion of exports, sustained 7% growth will remain elusive.
Manufacturing: The Forgotten Growth Engine
Manufacturing remains the single most important source of rapid economic transformation worldwide. Vietnam provides perhaps the best recent example.
Through (i) industrial zones, (ii) trade agreements, (iii) infrastructure development, and (iv) targeted investment attraction, Vietnam became deeply integrated into Asian production networks.
Sri Lanka possesses strategic advantages:
A prime Indian Ocean location
Strong port infrastructure
Educated labour force
Proximity to India
The country should establish specialised manufacturing clusters focusing on:
Electronics assembly
Medical devices
Processed food products
Boat building
Rubber-based products
Engineering components
Rather than attempting to compete with every country, Sri Lanka should specialise in selected niches where competitive advantages can be developed.
RCEP: The Strategic Door to Asia
Sri Lanka’s future lies increasingly in Asia.
The Regional Comprehensive Economic Partnership (RCEP) represents the largest trading bloc in the world and includes many of the fastest-growing economies.
Membership or closer integration with RCEP supply chains could provide Sri Lankan exporters with access to markets, investment, technology, and production networks that are currently beyond reach.
Unfortunately, discussion on RCEP remains limited compared with its strategic significance.
A dedicated national roadmap for RCEP engagement should become a top economic priority.
The question is not whether Sri Lanka can afford to integrate more deeply into Asia.
The question is whether Sri Lanka can afford not to.
Knowledge Economy: Turning Universities Into Growth Institutions
Sri Lanka’s universities produce thousands of graduates annually, yet their contribution to commercial innovation remains limited.
Globally, universities have become engines of economic development.
Research institutions should not merely produce graduates; they should produce patents, technologies, startups, and commercial solutions.
A national innovation framework should:
Link universities with industry
Encourage commercialisation of research
Support technology transfer
Expand startup financing
Reward innovation and entrepreneurship
Knowledge must become an economic asset rather than an academic exercise.
Dairy, Agriculture, And Import Substitution
Export growth alone is insufficient.
Sri Lanka must also reduce unnecessary import dependence.
The dairy sector offers a compelling example.
For decades, billions of rupees have left the country through dairy imports despite favourable climatic conditions and substantial agricultural potential.
A comprehensive dairy development strategy should focus on:
Improved genetics
Feed production
Commercial farming
Processing investment
Farmer productivity
The objective should be import substitution combined with rural income growth.
The same principle can be applied selectively to other sectors where domestic production is economically viable.
Creating A National Investment Targeting Agency
Sri Lanka does not need another bureaucracy.
It needs a professional institution dedicated exclusively to investment targeting.
Instead of passively waiting for investors, this agency would actively identify and attract strategic investments aligned with national priorities.
Its mandate would include:
Identifying priority sectors
Marketing opportunities globally
Coordinating approvals
Monitoring outcomes
Facilitating technology transfer
Singapore’s Economic Development Board and Ireland’s Industrial Development Agency demonstrate how targeted investment institutions can transform national economies.
Sri Lanka requires a similar mechanism adapted to local realities.
From Economic Diagnosis To Economic Engineering
The next stage of Sri Lanka’s recovery requires a fundamental shift in thinking.
The policy debate must move beyond identifying problems. The country already knows its problems.The challenge is implementation.Every policy proposal should be evaluated against a simple question:
Will this contribute to achieving 7% growth by 2029?
If the answer is no, resources should be redirected.
Economic engineering requires focus, prioritisation, accountability, and measurable outcomes. The era of fragmented initiatives must give way to a coherent national growth strategy.
Summary
Sri Lanka has achieved significant macroeconomic stabilisation, but stabilisation is only the first step toward sustainable prosperity.
To move from recovery to transformation, Sri Lanka should adopt a National Growth Strategy for 2026-2029 built around five pillars:
Export-led growth
Investment-led growth
Manufacturing expansion
Knowledge-economy development
Regional integration through RCEP and Asian supply chains
Supporting sectors such as dairy, tourism, logistics, and information technology should be strategically developed within this framework.
Most importantly, investment must be targeted rather than scattered, supported by specialised institutions and measurable performance indicators.
Conclusion
History demonstrates that no nation has become prosperous by accident. Economic success is rarely the product of isolated policies or short-term political initiatives. It is the outcome of a deliberate strategy pursued consistently over many years.
Sri Lanka stands at a crossroads.
One path leads to modest growth, periodic crises, recurring debt challenges, and continued vulnerability. The other leads to transformation through investment, exports, innovation, manufacturing, and regional integration.
The choice is ultimately strategic.
The time has come for Sri Lanka to move from economic diagnosis to economic engineering.
The future will not be determined by how successfully the country stabilised after the crisis. It will be determined by how effectively it builds the foundations for sustained growth thereafter. If Sri Lanka can articulate and execute a coherent investment-led growth strategy today, achieving 7% growth by 2029 need not be an aspiration.
It can become a national objective—and a national achievement, economic Engineering
