Why hide the truth about CKDu?

Published

By Dr PARAKRAMA WAIDYANATHA

An open letter to the new Minister of Health

The chronic kidney disease (CKDu) has been a major non-communicable disease prevalent essentially among the Rajarata’s agricultural communities in the last three decades that had, on average, killed several thousand people annually. The disease aetiology is now known, with a high degree of certainty to be hard water in dug wells on high ground contaminated with fluoride. Because it largely affected the farming families, agro-chemicals were justifiably suspected as the cause although without evidence; and many, especially the ignorant politicians, including several key ministers without knowing the facts of the matter, have blamed agrochemicals.

In fact, the term wasa visa krushikarmaya (toxic- agriculture) was coined on conventional agriculture largely because of the misinformation. Ridiculous boards displaying that fruits and vegetables sold in wayside shops are ‘toxin-free’ have been a common sight. The shopkeeper hardly knows the origin of the produce!

Then, there was the much-hyped ‘toxin-free agriculture” or organic farming drive of the Yahapalana government, led by the then President and Ven. Ratana, which again was on the premise that agrochemicals are the cause of the disease. It was, however, a total failure. And it would appear that the current President too, rushed to organic farming with the misinformed judgment that agrochemicals are the cause of CKDu, and probably also of other non-communicable ones, although there has been no evidence for it! He should have consulted the scientists and academics in the relevant fields before rushing to the decision.

However, the new Finance Minister has, in a recent gazette notification, dated 31st July 2021, claimed to be published in order to “regulate the importation of chelated minerals and micronutrients” which were previously banned, has also ‘surreptitiously’ reverted the Presidential decision; allowing imports of virtually all straight chemical fertilizers and mixtures thereof, but on license! So, hopefully, farmers should have access to chemical fertilisers for the coming Maha season!

Be all that as they may, the writer’s concern is that despite the overwhelming research, as also supportive numerical evidence the Health Ministry/Department has been generating on the prevalence of CKD, through a broad surveillance with nationwide sentinel sites that has also supported the observation that drinking water quality is the major cause of the disease, it has hitherto made no formal pronouncement on the disease causation. Regrettably, neither the former Health Minister nor the Agriculture Minister seem to be aware of this fact, from the utterances they have made recently in Parliament and outside. In fact, both of them were seen yelling in Parliament, some days ago, that the cause for the kidney disease is agrochemicals! Further, at a meeting with the farmers some weeks ago, the Agriculture Minister exclaimed that the government has rushed into organic farming to save the kidneys of farmers!

Mr. Minister, please be aware of the following facts and take necessary action to clear the myth in the minds of the President, ministers and other authorities, that agrochemicals are the cause of CKDu, the number one non-communicable in the country:

1.

The scientific and medical community have developed an understanding of the origins of this chronic disease. Steps to control it have shown increasing success as the numbers stricken by the disease have decreased since 2016, following supply of clean drinking water to the residents of the endemic areas. And it is now critically important that people of all affected areas are provided with good quality drinking water. Apparently, when the Yapahalana authorities then “flogging the dead agrochemical horse” came to learn that polluted water was the cause of the disease, rumour was doing the rounds, that the authorities did not want people told about it for fear of an outcry for quality water!

2.

Research by at least five groups and many individuals, local and foreign, have shown that the disease is caused by the consumption of water from wells containing hard water and fluoride, found in geological formations known as Regolith aquifers that hold the water in the relevant dry zone areas. People who were settled rapidly during the Accelerated Mahaweli Programme on higher ground in the late 1970s, had to dig shallow wells or tube wells for their water supply. Estimates reveal that there are some 176,000 such wells in the Rajarata! CKDu is found essentially in villages drinking water from such wells. Residents who get their water from agricultural canals, rivers or reservoirs DO NOT CONTAMINATE CKD, whereas one would have expected them to do so if agrochemicals were the cause of the disease. Please see the attached graph (Fig. 1) from a publication by none other than Dr Asanga Ranasinghe, Coordinator of the CKDu Programme, Ministry of Health and others (BMC Nephropathy, Aug 2019) that reveal a sharp drop in the number of patients in the two most CKD affected districts of Anuradhapura and Polonnaruwa. This was a consequence of provision of safe drinking water, and in fact the people themselves in the affected areas realised that polluted water was the cause of the disease, and not drinking it. Further, the Table 1 below compiled from the data of 2018 Annual Health Bulletin (page 70), also confirm a sharp decline in the increase in patient numbers from 52% between 2014 and 2016 to just 12% between 2016 and 2018, which should essentially be a consequence of drinking good quality water. There is no other evidence to explain this prominent decline.

Sadly, however, the 2019 Annual Health Bulletin does not carry any information on the CKDu status, despite there being a nationwide Sentinel Survey of patient numbers; and the 2020 Annual Health Bulletin too has not been published to date! Why are the health authorities so negligent about the number one non-communicable disease in the country! Table 1

3. There is CKDu in areas like Mullaitivu where no agro-chemicals whatsoever have been used due to the Eelam wars. So it is now amply evident that residents who drink hard water rich in fluoride contract CKDu, but not those who drink water from streams, reservoirs and wells in the planes.

4.

No CKDu is found in the Hill Country (vegetable and tea cultivation) and in most other areas such as Kalpitiya (vegetable cultivation) where agrochemicals are used much more heavily than in the Rajarata.

5.

The WHO Report, 2013, concluded, amongst other things, that some CKDu patients secreted pesticide residues above the reference (permissible) levels, but did not refer to the pesticide residue status in the urine of the control subjects (from Hambantota) in the trial! Our subsequent analysis of the pesticide residue raw data, revealed that the numbers of subjects with urine pesticide levels were two to three times higher from the non-CKD (Control) area than among the CKD patients (See Table 2). Why did the WHO Report omit this critically important control data? Referring to pesticides, the Report merely stated that some CKDu patients had residues of some pesticides above reference limits! Was it to give the impression that pesticides were probably the cause? However, an International Expert Consultation held in 2018 on CKDu in Colombo, concluded that there is no evidence to implicate agrochemicals in the causation of the disease.

6.

Several ministers and most importantly even the President of the GMOA, Dr Padeniya have been repeatedly claiming that Sri Lanka is the country consuming the highest quantities of agrochemicals in the world. However, the published data of the World Bank (see Table 3) reveals that in this part of the world, we are the country consuming the lowest amount of fertiliser and the second lowest amount of pesticide per unit area!

In conclusion, the disease is evidently caused by consuming naturally contaminated well water. It has nothing to do with fertilisers or pesticides. The disease is prevented by supplying clean water to the endemic villages. This has been done largely by the distribution of rain-water collection tanks, and by the installation of reverse-osmosis water filtration plants by benevolent donors. Moreover, people in the affected areas are now aware of the cause of the disease and are taking preventive measures themselves, as evident from the data.

Please bring this information to the attention of the President and other authorities, so that vital national decisions are based on facts, and not myths!

A tariff deal with the US? Make haste slowly

Published

on

by Gomi Senadhira

Sri Lanka’s former ambassador to the United States Mahinda Samarasinghe is back in Sri Lanka lobbying for speedier finalisation of a new tariff deal with the United States. According to news reports, delivering the keynote address at the Sri Lanka Institute of Directors’ Annual Meeting last week, he stated, “I have recommended very strongly to the government that we need to conclude the agreement so that we can lock in the very favourable tariff rate that Sri Lanka has got up to now“.

I do not understand why the former ambassador is urging the government to expedite the finalisation of a new tariff deal or what is “the very favourable tariff rate” he refers to in his speech. However, given the ongoing terrible tariff turbulence in the United States and the fragile economic situation in Sri Lanka, I believe, this is not the right time to rush into finalising any trade agreement with the United States. I am also of the opinion that at this juncture Sri Lanka should maintain strategic patience and explore all available options.

Lessons from the countries that rushed for trade deals

To better comprehend this, let’s look at experiences of the countries that rushed to conclude tariff deals with the United States after President Donald Trump declared his “reciprocal tariffs” under the International Emergency Economic Powers Act (IEEPA) in April 2025. As Samarasinghe stated in his keynote, “The bottom line on all these negotiations was that every country that finally agreed to sign the agreement had to give either complete duty-free access for American exports into those markets, or near complete duty-free access.” In exchange for these tariff concessions and other market access commitments these countries managed to get the newly introduced country specific “reciprocal tariffs” reduced.

However, in February 2026, the Supreme Court of the United States (SCOTUS) struck down these “reciprocal tariffs” under the IEEPA. With that, the market access gains these countries received in exchange for complete duty-free access for American exports into their markets evaporated under U.S. domestic law. By moving too fast to conclude bilateral tariff agreements with the United States these countries are now bound to strict obligations whereas the benefits they bargained from the U.S. administration are not worth the paper those were written on.

Sri Lanka’s experience

In April 2025, President Trump declared his “reciprocal tariffs” and labelled Sri Lanka as the worst offender, imposing one of the highest additional duties at 44%. Since then, Ambassador Samarasinghe and other negotiators have managed to negotiate this down to 20%. I do not know what the deal was through which Sri Lanka managed to reduce the 44% tariff to 20% or what we gave in return for this “concession.” However, what we received in return has absolutely no value after the decision by the SCOTUS.

Current state of US tariffs

After the decision by SCOTUS, the U.S. administration introduced a temporary 10% additional tariff on all countries for 150 days. At the end of that period, this 10% tariff was replaced by a new “forced labor tariff ” of 10% to 12.5% on all trading partners under Section 301 of U.S. trade law. Twenty-five U.S. states and several small businesses have already filed lawsuits against these tariffs in U.S. courts. This new “forced labour tariff ” on Sri Lanka was first fixed at 12.5%. Later, after President Anura Kumara Dissanayake issued a gazette notice prohibiting the importation of goods produced using forced labour, it was reduced to 10%. That means Sri Lanka has already made a substantial commitment to receive this “tariff concession,” and I presume our negotiators understand the implications of this commitment.

Make haste slowly

After President Trump imposed 44% “reciprocal tariffs” on Sri Lanka, through an article published in The Island on 25th April 2026 (), I urged the government to engage immediately with the US administration on these tariffs. However, I also emphasised that the best way to move forward was to make haste slowly.

Two millennia ago, Augustus Caesar, the first emperor of Rome, frequently used the phrase, “make haste slowly”, because he detested rashness and haste in his military commanders. It was the recurring guiding maxim that he emphasised throughout his 40-year imperial rule. After 2000 years, this classical oxymoron remains a definitive golden rule for professional trade negotiators. More importantly it is the exact blueprint required when navigating turbulence in trade negotiations with the Trump administration.

The endgame – The most dangerous moment in trade negotiation

Samarasinghe has also stated the agreement is 90% complete. Any experienced trade negotiator should know that the final 10% contains high-stakes provisions and is the most dangerous moment in a trade negotiation. A single misplaced comma or ambiguous product description in a tariff schedule can cost millions through unintended loopholes. Rushing this last stretch to secure a deal can permanently expose Sri Lanka to sudden shifts in American trade policy, heavy compliance costs, or strict enforcement under Section 301 regarding supply-chain labour standards. Hence, this is the time for strategic patience.

Buddhist law and constitutional amendments

Published

on

Upon reading the article titled “Prof. Pieris says Buddha Dhamma recognized as source of law under Constitution” (Island, September 12, 2026), the classical Sinhala idiom “Yanne Koheda? Malle Pol” immediately comes to mind. The expression, translating literally to answering “I have coconuts in my bag” when asked “Where are you going?”, underscores a complete disconnect in logic. Because it is uncertain whether the article accurately represents the professor’s precise words, the following critique addresses the contents of the report rather than the speaker himself.

The central premise of the report concerns a statement delivered by the Chief Justice regarding a petition filed against the 22nd Amendment to the Constitution. According to the report, the Chief Justice’s observation that the determination would be made strictly on the basis of established law rather than Buddhist teachings was characterised as a “cavalier dismissal” of the Buddha Dhamma. This assertion carries a host of unexamined assumptions. Had the writer specified precisely which tenets of the Buddha Dhamma were violated, a direct legal or philosophical evaluation could take place. However, no specific Buddhist tenet or law was identified as having been transgressed, and for good reason: no such statutory legal framework exists within the Buddha’s teachings.

To understand the flaw in this argument, one must examine the constitutional context alongside the canonical meaning of the terms involved. Article 9 of the 1978 Constitution of Sri Lanka mandates that the Republic shall give Buddhism the foremost place and that it shall be the duty of the State to protect and foster the Buddha Sasana, while guaranteeing the fundamental rights of all religions under Articles 10 and 14(1)(e).

While “Buddhism” and “Buddha Dhamma” are frequently used as interchangeable terms in casual dialogue, they represent distinct concepts. “Buddhism” is an umbrella term coined by 19th-century Western scholars to classify the global institutionalised religion, incorporating its diverse sects, cultural traditions, rituals, and socio-political histories. Conversely, Sasana is the ancient term designating the structural framework established by the Buddha to preserve and transmit his teachings, comprising the monastic order (Sangha) and its supporting institutions.

In classical Theravada commentarial literature, the Sasana operates as a functional three-tiered structure. It encompasses Pariyatti Sasana, the preservation and study of sacred texts; Paṭipatti Sasana, the practical execution of the doctrine through ethical conduct and meditation; and Paṭivedha Sasana, the direct experiential realization of ultimate truth, or enlightenment. This structural breakdown raises fundamental questions about state capacity. While a state can readily support Pariyatti Sasana through academic institutions, textual preservation, and educational funding, it cannot legislate or enforce Paṭipatti or Paṭivedha. Practical engagement and spiritual realisation are inherently internal, first-person experiences. Expecting the state to codify or guarantee enlightenment is a conceptual impossibility.

Furthermore, the Buddha Dhamma refers specifically to the unconditioned truths of existence and the teachings imparted to realize them, including the Four Noble Truths, the Eightfold Path, and Dependent Origination. As the late Venerable Professor Kotagama Wachissara Thera observed, there is no rigid ideologue or “ism” in the core Dhamma. The teachings do not constitute a system of divine commandments or a legal statute enforced through reward and punishment. Rather, Buddhist ethics function as self-directed guidelines for psychological clarity and moral inquiry. Even the Vinaya Pitaka, which contains explicit rules of conduct, functions as an internal monastic code rather than a civil or criminal law intended for the laity.

Throughout the Pali Canon, guidance regarding governance focuses on the moral character of leadership and the social duties of statecraft rather than rigid legal codification. In discourses such as the Cakkavatti Sihanada Sutta (DN 26), the Buddha observes that social instability and crime cannot be eliminated solely through punitive measures, emphasising instead that states must provide economic opportunities, fair wages, and resource distribution to maintain societal balance. Crucially, in the Maha Parinibbana Sutta (DN 16), the Buddha explicitly highlights the importance of respecting established laws and traditions rather than enacting arbitrary regulations.

The natural laws articulated in the Dhamma, such as the law of cause and effect or the three characteristics of existence, govern all phenomena universally, regardless of legal statutes or personal belief. They are not human laws to be applied or suspended by a court of law. Therefore, characterizing the Chief Justice’s adherence to constitutional jurisprudence over religious doctrine as a “cavalier dismissal” lacks logical and textual foundation. Framing the judiciary’s adherence to legal precedent as an attack on the Dhamma distracts from fundamental constitutional principles and risks misguiding the public for political ends.

Elementary, Dr. Watson!

Published

by Usvatte

My friend, Sena Thoradeniya, has summoned up energy to raise two questions about my observations in your newspaper on 14 September, 2026. They both referred to comments I made about President Dissanayake and Prime Minister Amarasuriya.

I observed that President Dissanayake, having graduated in physics at Kelaniya, would be familiar with elementary calculus: differentiation and integration. It is a misapprehension to believe that one needs any knowledge of theoretical physics to be familiar with elementary calculus. Nor is it necessary that one needs to have published research for the same purpose. Those were the first lessons in calculus that our Mathematics Master and Principal, Mr. D. A. Devendra taught five of us in the first term 1952 at Hikkaduva Central School. Of the five, two still live and recall those lessons vividly. Dissanayake would surely have learnt them at his school in Anuradhapura. At Kelaniya his teachers probably included Dr. H. Somadasa, two years my junior at Hikkaduva, with a Ph.D. in number theory at Aberytswyth, Wales and Professor (physics) Charles Dahanayke, a renowned teacher of physics and my neighbour in Colombo. Dissanayake is unlikely to have been admitted to Physics at Kelaniya unless he had scored well in mathematics and physics with other subjects. Those elements of calculus have been learnt by millions of young men (and later women) since Isaac Newton and Gottfried Leibnitz. That Dissanayake from a school in Anuradhapura scored high enough to gain admission to Kelaniya to study physics is commendation enough for his intellectual capacity.

All of us know, some personally, the barriers to learning in places like Anuradhapura and Kuliyapitiya, compared to the facilities in Colombo, Galle. Jaffna and Kandy. I used that information to press the point that he was, in learning, entirely different from his predecessors and present competitors. One does not need to research in theoretical physics to know something as simple as the first lesson in calculus. Dirac made his momentous discovery sometime in the 1930s and by 1950 it must have been solidly in the teaching material in schools and universities. Dissanayake graduated in 1995 and, at least, must have heard of Dirac and the ‘God Particle’.

Paul Dirac was a legendary figure among graduate students when I was at Cambridge. He had written the shortest Fellowship and Ph.D. theses. He had had an interesting relationship with his father who was a French speaking Swiss and had insisted that he speaks French at table. Amrtya Sen, who was in 1965 a young Fellow of Trinity College and a teacher in the Economics and Politics Faculty at that time, had also written very short theses and not several volumes as many do.

I read about Higgs Boson in a wonderful book Inward Bound written by physicist Abraham Pais and, in The Science Times (Tuesdays) edited by Gina Kolata of the New York Times, and occasionally in Nature and other popular writings.

I was on the editorial board of Samskrti for some time. Amaradasa Virasinghe and Gananath Obeysekera had started that literary review in 1953 when I was in school and many of us read it avidly. Together with Susil Sirivardana, we decided to expand the scope of the journal to include social studies and science, which effort Sena knew well. The probable readership had increased manifold. In order to help prospective writers to pick up themes to write on, we held a popular lecture, one Saturday a month. I invited Dr. Harini Amarasuriya, then teaching at the Open University, Nawala, to speak to us on the scope and nature of sociology. She made a short fine introduction. That is where I learnt of August Compte. She was invited to a Seminar in Britain on the sociology of education, where I had strayed into from 1971. I did not read her paper, although she had promised to let me have it. I had good reason to respect her scholarship. It would be shocking had she not read Le`vy-Strauss. Many besides anthropologists read Le`vy-Strauss.

Sena stressed the obvious when he said that in public speeches made by these two politicians, there was no evidence of their expertise in physics and sociology. It would have been completely out of place to speak about elementary particles to a crowd in Beruvala or Anuradhapura. But one’s education, in subtle ways, informs the material and the ways that the material is presented in public speeches. Simply listen to Members of Parliament speak and you can guess roughly the level of education each had achieved: grade 2 in primary school or Quondam Professor of Law at Oxford.

I am sorry that Sena identified ‘an exaggerated parade of claims and sheer implausible boasts’ in what I wrote. It is entirely plausible, indeed certain, that an undergraduate in the Department of Physics in any university would be familiar with differentiation and integration.

An unprejudiced reading of my text will demonstrate that it contained no such claims and boasts. Mine was a pretty simple statement of the nature of differences between the present lot in government and the lots that were in power earlier. I related those differences to help understand the line up for and against the 22nd Amendment to the Constitution. and not to build false images of any politician, man or woman. I am too old to set out, even in the formidable company of Sena, on the ‘long march’ to Mao.
