Save Parakrama Samudraya!

By Bandula Kendaragama, Dam Safety Consultant, Melbourne, Australia

This article is written based on information collated through consultations that were submitted as a technical report recently to President Gotabaya Rajapaksa and other relevant government authorities. The consultations were among those who had been interested in dam safety and directly involved in managing the “Narrowly-Missed” breach and in the reconstruction of the Parakrama Samudraya bund after the Cyclone in 1978. They considered it appropriate in sharing concerns and acquired knowledge with the public at this crucial juncture of decision-making on the safety of the aging irrigation infrastructures in Sri Lanka.

The Parakrama Samudraya Reservoir was built by King Parakramabahu the Great, during his reign (1153-1186 AD) and it has a reservoir capacity of 116,000 acre-feet, feeding approximately 25,000 acres of paddy cultivation. This reservoir has a bund 52 feet high and 10 miles long.

The study on the Parakrama Samudraya bund was undertaken owing to information and misinformation that had been widely shared and debated in the formal media, and especially in the social media, concerning the Parakrama Samudraya bund being proposed as a site to construct an 8-feet wide walking path. Further, it is noted that similar walking paths will be constructed on bunds of other reservoirs such as Kantale, Udukirala Wewa, etc.,

Cyclone in 1978

The 1978 Cyclone started with the onset of the storm formed on 20 November 1978 over the southwest Bay of Bengal. It intensified gradually, reaching Super Cyclonic Storm Status Category 4 Cyclone on 23 November with a gusty wind speed of 220 kmph. The 1978 Cyclone was the second strongest Super Cyclonic Storm to strike Sri Lanka’s Eastern Province since modern records began. The cyclone attained peak intensity on November 23, before making landfall in Batticaloa. The Eastern Province was heavily affected by the cyclone.

The cyclone had devastating impacts in Sri Lanka, killing about 915 people and an unaccounted number of cattle and other animals. An estimated more than one million people were affected, with over 250,000 buildings damaged, and one-fifth of Batticaloa’s fishing fleet destroyed. Nine of the 11 paddy stores were destroyed and 90 % of the coconut plantation (about 28,000 acres) in the Batticaloa district were destroyed. Also, in Polonnaruwa District, the public and private infrastructure, paddy, and rice stored in Food Commissioners and Cooperatives, coconut cultivation, etc., were devastated.

Cyclone 1978 and Parakrama Samudraya

The Cyclone reached the Parakrama Samudraya bund at about 6:30 pm on 23 November and lasted till about 4:00 am on 24 November. According to eyewitnesses, the height of the waves was 10 to 12 feet. Knowing the imminent catastrophic danger of overtopping leading to a breach of the bund, the Irrigation Engineer in charge of Polonnaruwa A. D. S. Gunawardana, the Government Agent Polonnaruwa Austin Fernando, and a few other officials, on duty, decided to be ready with a few bulldozers and retain them standby at strategic locations such as at the sluice and spillway, to breach the bund at these locations if the need arises.

The idea behind this decision was if the predicted overnight rainfall occurred and the anticipated inflow to the Parakrama Samudraya did really eventuate, the inflow would have been greater than the outflow with all 10 radial gates and the sluice gates kept open. Then there was a risk of overtopping and breaching the bund. Hence, an artificially introduced breach of the bund to discharge floods along the existing channels would prevent a haphazard catastrophic breach at an unknown and unwanted location, which could inundate the heavily populated downstream areas. Such an emergency rapid drawdown is the standard practice to prevent a dam breach. Fortunately, predicted overnight rainfall was low. However, the drawdown of the reservoir continued overnight.

Following the overnight drawdown, about 2/3 of the 12-feet wide bund top road and a fair portion of the upstream shoulder were found to be slipped into the reservoir, leaving only about 1/3 of the bund top road intact. There were widespread such slips along the full length of the bund. The damaged areas were repaired with earthfill and Ralapanawa reinstated as a short-term risk reduction measure. The upstream face of the Ralapanawa was not flattened to improve the safety margin (i.e., Factor of Safety) of the bund in case of future similar drawdowns as it was a long-term risk reduction measure to be implemented by the Government Authorities. Therefore, consideration should be given to implementing appropriate long-term risk reduction measures.

Walking Track Proposal

Based on information available to date, the proposed walking path will be constructed on the upstream side of the bitumen surfaced bund top road where there was a sliding failure during the 1978 cyclone and floods (See Figure above 1).

Several long tension cracks, sealed with tar, are present on the bitumen surfaced bund top road as seen in videos of Sri Lanka media. Most of them are located along (parallel) the bund top road, thus increasing the risk of sliding failures similar to those that occurred during the 1978 floods. Additional loads due to the construction of a walking path would widen and deepen those tension cracks, compromising the safety of the bund, which is not known.

Therefore, it is the considered view that additional loading on top of the 1978 sliding mass for construction of the walking path would increase the risk of reactivating the 1978 slides during a future rapid drawdown, similar to in 1978.

It is understood and appreciated that the Irrigation Department is currently undertaking geotechnical investigations to assess the safety margin of the bund.

The highest concern is dam-safety

Based on information available, it is understood that there is a period of 741-years (i.e., from 1159 to 1900), where the performance of the bund is not documented and unknown. However, it is reported that the bund was totally breached during the colonial era. According to R L Brohier, the bund and the reservoir were abandoned for more than a century.

Given that the population at risk in case of a dam break is extremely high, it appears that the consequence category of this bund is “Extreme” as per the current international dam safety guidelines. Therefore, the proposed walking path at Parakrama Samudraya cannot be compared to that of the Kurunegala Wewa, Boralesgamuwa Lake, etc., constructed along the reservoir rim, and the walking paths constructed around water bodies in the suburbs of Colombo.

It is understood that the Parakrama Samudraya is formed by combining three reservoirs of unknown history. Therefore, the bund may have been raised in several stages during the 741-years associated with unknown performance. It is not known whether dam safety-related defects of the bund such as slips or slides, cracks, animal burrows, sinkholes, soft areas, root bowls, zones of desiccation cracking, zones of residual shear strength because of historical failures, etc., were repaired to satisfactory standards, or not.

The aging of dams constructed of earth and rockfill material is due to time-related changes in the properties of the materials of the structure and its foundation. As reported in a technical paper published in May 2010 by the United States Society of Dams, the aging or deterioration of embankment dams and their foundations are of concern. These concerns extend throughout the entire life of the dam until safe abandonment or demolition.

Recent interventions on dam-safety

Given the dam safety issues associated with this controversial walking path project, the Water Forum of the Institute of Engineers in Sri Lanka conducted a Webinar on 09 September 2021 on “Usage of Inland Water Bodies for Recreation”. More than 280 personnel, mainly engineers, participated in this Webinar and raised over 100 questions related to the safety of the bund. Several questions were raised on fundamental errors and potential failure modes associated with the proposed walking path. It appears that ad hoc decisions have been taken for reasons unknown. The lack of laws and dam safety regulations in Sri Lanka could be one of the reasons for such ad hoc decisions taken by various individuals and organisations.

As far as dam safety regulations are concerned, India is well ahead of Sri Lanka. Even Ghana in Africa has introduced Dam Safety Regulations to ensure the safe design, construction, operation, and maintenance as well as decommissioning of dams.

Based on statistics of embankment dam failures and accidents, 48% of dam failures are related to overtopping and failures of appurtenant structures, and 46.5% are due to internal erosion. Due to the absence of an internal filter system in this bund, not only the slope instability, but the internal erosion is also likely to be a prominent potential failure mode.

It is understood that planning is underway to construct several fast-food outlets, toilet facilities (including a “changing room”) at the toe of the bund, i.e., within the reservation area of the bund located immediately downstream of it. It is to be stressed that this stretch of land along the bund is a critical area to ensure the safety of the bund. Identification of dam safety features such as heaving the ground, cracks, wet areas, springs, seepage locations, etc., in this area, is critical. Digging of lavatory pits, trenches, etc., could intercept permeable layers in the foundation and may trigger “backward erosion tunnels” leading to piping, which is a major failure mode in embankment dams (or, bunds). Excavations in this area could lead to sides of the downstream face of the bund, compromising its safety margin.

Should there be a need to improve the safety margin of the bund, additional stabilizing fills are to be constructed in this area over the downstream face of the existing bund. An access road along the downstream toe of the bund is an essential item for repairs and routine maintenance of the bund. Given the proximity to the dam, this reservation area should be used to stockpile materials to be used during dam emergencies such as filter sand, crushed rock, rockfill, etc., and movement of construction machinery for maintenance and repairs. This area is an integral part of the bund, hence should not be used for either permanent or temporary constructions. Therefore, consideration should be given to providing these facilities at an alternate suitable location, perhaps close to the Government Agent’s residence, or thereabouts.

Recommendations to maintain dam safety

Based on dam safety concerns and consequences discussed, it is recommended that,

1) the crest of the bund is reserved for routine maintenance, including replacement of displaced Ralapanawa if necessary, placement of additional boulders if required, and for construction of temporary overtopping protection bund using ‘Sandbags”, as and when required.

2) the stretch between the Ralapanawa and bitumen road be reserved for the construction of a wave wall to meet the dam safety requirements of future hydrological reviews to be undertaken during the service life of the reservoir and bund.

3) a safe “Load Capacity” be imposed on the bund top road, and arrangements are made to stop all heavy trucks plying on the bund top road as the bund has not been designed for such traffic loads.

4) the bund top road is completely closed for all traffic, say from 5:30 am to 7:30 am and then from 6:00 pm to 9:00 pm or as agreed by local authorities, in the preferred 2km long stretch, and then the existing bitumen surfaced bund top road to be used as the walking path (Alternatively, only the upstream-half of the bitumen surfaced bund top road to be used as the walking path while the downstream-half of the bitumen surfaced bund top road to be kept open for one-way light traffic only, subject to nominated maximum speed to ensure the safety of people using the walking path).

5) an alternative walking path (For example, in the reservoir rim), be investigated which will not compromise the safety of the dam.

6) the reservation area located immediately downstream of the bund is not used for developments that are been planned by the Urban Development Authority as this area is very sensitive to dam safety issues.

7) the reservation area located immediately downstream of the bund, which is an integral component of the dam, be a property of the Irrigation Department for inspection and monitoring of critical dam safety features, construction of a toe access road, construction of stabilizing fills if required, stockpiling of construction materials required during dam emergencies, etc.,

8) a potential failure modes analysis and Risk Assessment be undertaken in accordance with international dam safety standards.

9) a Design and Safety Review of the dam and appurtenant structures be undertaken in accordance with the international dam safety standards incorporating review of geotechnical parameters of the bund and foundation, hydrology, wave run-up, seismicity, flood handling capacity, reliability of gates and instrumentation, etc.,

10) sufficient funds must be allocated to undertake Design and Safety Reviews of all “Extreme” consequence category dams in Sri Lanka.

11) sufficient funds must be allocated to routine maintenance of dams (Note: Depending on their nature, some maintenance items, if not addressed in a systematic and timely manner, may eventually become dam safety issues, eventually leading to failure of dams).

12) early arrangements must be made to implement the recommendations of the Cabinet Memorandum No. 11-2020 dated 26 October 2020 on the Establishment of a Dam Safety Consultation Centre and a Dam Safety Regulatory Mechanism.

Child food poverty: A prowling menace

In an age of unprecedented global development, technological advancements, universal connectivity, and improvements in living standards in many areas of the world, it is a very dark irony that child food poverty remains a pressing issue. UNICEF defines child food poverty as children’s inability to access and consume a nutritious and diverse diet in early childhood. Despite the planet Earth’s undisputed capacity to produce enough food to nourish everyone, millions of children still go hungry each day. We desperately need to explore the multifaceted deleterious effects of child food poverty, on physical health, cognitive development, emotional well-being, and societal impacts and then try to formulate a road map to alleviate its deleterious effects.

Every day, right across the world, millions of parents and families are struggling to provide nutritious and diverse foods that young children desperately need to reach their full potential. Growing inequities, conflict, and climate crises, combined with rising food prices, the overabundance of unhealthy foods, harmful food marketing strategies and poor child-feeding practices, are condemning millions of children to child food poverty.

In a communique dated 06th June 2024, UNICEF reports that globally, 1 in 4 children; approximately 181 million under the age of five, live in severe child food poverty, defined as consuming at most, two of eight food groups in early childhood. These children are up to 50 per cent more likely to suffer from life-threatening malnutrition. Child Food Poverty: Nutrition Deprivation in Early Childhood – the third issue of UNICEF’s flagship Child Nutrition Report – highlights that millions of young children are unable to access and consume the nutritious and diverse diets that are essential for their growth and development in early childhood and beyond.

It is highlighted in the report that four out of five children experiencing severe child food poverty are fed only breastmilk or just some other milk and/or a starchy staple, such as maize, rice or wheat. Less than 10 per cent of these children are fed fruits and vegetables and less than 5 per cent are fed nutrient-dense foods such as eggs, fish, poultry, or meat. These are horrendous statistics that should pull at the heartstrings of the discerning populace of this world.

The report also identifies the drivers of child food poverty. Strikingly, though 46 per cent of all cases of severe child food poverty are among poor households where income poverty is likely to be a major driver, 54 per cent live in relatively wealthier households, among whom poor food environments and feeding practices are the main drivers of food poverty in early childhood.

One of the most immediate and visible effects of child food poverty is its detrimental impact on physical health. Malnutrition, which can result from both insufficient calorie intake and lack of essential nutrients, is a prevalent consequence. Chronic undernourishment during formative years leads to stunted growth, weakened immune systems, and increased susceptibility to infections and diseases. Children who do not receive adequate nutrition are more likely to suffer from conditions such as anaemia, rickets, and developmental delays.

Moreover, the lack of proper nutrition can have long-term health consequences. Malnourished children are at a higher risk of developing chronic illnesses such as heart disease, diabetes, and obesity later in life. The paradox of child food poverty is that it can lead to both undernutrition and overnutrition, with children in food-insecure households often consuming calorie-dense but nutrient-poor foods due to economic constraints. This dietary pattern increases the risk of obesity, creating a vicious cycle of poor health outcomes.

The impacts of child food poverty extend beyond physical health, severely affecting cognitive development and educational attainment. Adequate nutrition is crucial for brain development, particularly in the early years of life. Malnutrition can impair cognitive functions such as attention, memory, and problem-solving skills. Studies have consistently shown that malnourished children perform worse academically compared to their well-nourished peers. Inadequate nutrition during early childhood can lead to reduced school readiness and lower IQ scores. These children often struggle to concentrate in school, miss more days due to illness, and have lower overall academic performance. This educational disadvantage perpetuates the cycle of poverty, as lower educational attainment reduces future employment opportunities and earning potential.

The emotional and psychological effects of child food poverty are profound and are often overlooked. Food insecurity creates a constant state of stress and anxiety for both children and their families. The uncertainty of not knowing when or where the next meal will come from can lead to feelings of helplessness and despair. Children in food-insecure households are more likely to experience behavioural problems, including hyperactivity, aggression, and withdrawal. The stigma associated with poverty and hunger can further exacerbate these emotional challenges. Children who experience food poverty may feel shame and embarrassment, leading to social isolation and reduced self-esteem. This psychological toll can have lasting effects, contributing to mental health issues such as depression and anxiety in adolescence and adulthood.

Child food poverty also perpetuates cycles of poverty and inequality. Children who grow up in food-insecure households are more likely to remain in poverty as adults, continuing the intergenerational transmission of disadvantage. This cycle of poverty exacerbates social disparities, contributing to increased crime rates, reduced social cohesion, and greater reliance on social welfare programmes. The repercussions of child food poverty ripple through society, creating economic and social challenges that affect everyone. The healthcare costs associated with treating malnutrition-related illnesses and chronic diseases are substantial. Additionally, the educational deficits linked to child food poverty result in a less skilled workforce, which hampers economic growth and productivity.

Addressing child food poverty requires a multi-faceted approach that tackles both immediate needs and underlying causes. Policy interventions are crucial in ensuring that all children have access to adequate nutrition. This can include expanding social safety nets, such as food assistance programmes and school meal initiatives, as well as targeted manoeuvres to reach more vulnerable families. Ensuring that these programmes are adequately funded and effectively implemented is essential for their success.

In addition to direct food assistance, broader economic and social policies are needed to address the root causes of poverty. This includes efforts to increase household incomes through living wage policies, job training programs, and economic development initiatives. Supporting families with affordable childcare, healthcare, and housing can also alleviate some of the financial pressures that contribute to food insecurity.

Community-based initiatives play a vital role in combating child food poverty. Local food banks, community gardens, and nutrition education programmes can help provide immediate relief and promote long-term food security. Collaborative efforts between government, non-profits, and the private sector are necessary to create sustainable solutions.

Child food poverty is a profound and inescapable issue with far-reaching consequences. Its deleterious effects on physical health, cognitive development, emotional well-being, and societal stability underscore the urgent need for comprehensive action. As we strive for a more equitable and just world, addressing child food poverty must be a priority. By ensuring that all children have access to adequate nutrition, we can lay the foundation for a healthier, more prosperous future for individuals and society as a whole. The fight against child food poverty is not just a moral imperative but an investment in our collective future. Healthy, well-nourished children are more likely to grow into productive, contributing members of society. The benefits of addressing this issue extend beyond individual well-being, enhancing economic stability and social harmony. It is incumbent upon us all to recognize and act upon the understanding that every child deserves the right to adequate nutrition and the opportunity to thrive.

Despite all of these existent challenges, it is very definitely possible to end child food poverty. The world needs targeted interventions to transform food, health, and social protection systems, and also take steps to strengthen data systems to track progress in reducing child food poverty. All these manoeuvres must comprise a concerted effort towards making nutritious and diverse diets accessible and affordable to all. We need to call for child food poverty reduction to be recognized as a metric of success towards achieving global and national nutrition and development goals.

Do opinion polls matter?

Published

on

By Dr Upul Wijayawardhana

The colossal failure of not a single opinion poll predicting accurately the result of the Indian parliamentary election, the greatest exercise in democracy in the world, raises the question whether the importance of opinion polls is vastly exaggerated. During elections two types of opinion polls are conducted; one based on intentions to vote, published during or before the campaign, often being not very accurate as these are subject to many variables but exit polls, done after the voting where a sample tally of how the voters actually voted, are mostly accurate. However, of the 15 exit polls published soon after all the votes were cast in the massive Indian election, 13 vastly overpredicted the number of seats Modi’s BJP led coalition NDA would obtain, some giving a figure as high as 400, the number Modi claimed he is aiming for. The other two polls grossly underestimated predicting a hung parliament. The actual result is that NDA passed the threshold of 272 comfortably, there being no landslide. BJP by itself was not able to cross the threshold, a significant setback for an overconfident Mody! Whether this would result in less excesses on the part of Modi, like Muslim-bashing, remains to be seen. Anyway, the statement issued by BJP that they would be investigating the reasons for failure rather than blaming the process speaks very highly of the maturity of the democratic process in India.

I was intrigued by this failure of opinion polls as this differs dramatically from opinion polls in the UK. I never failed to watch ‘Election night specials’ on BBC; as the Big Ben strikes ‘ten’ (In the UK polls close at 10pm} the anchor comes out with “Exit polls predict that …” and the actual outcome is often almost as predicted. However, many a time opinion polls conducted during the campaign have got the predictions wrong. There are many explanations for this.

An opinion poll is defined as a research survey of public opinion from a particular sample, the origin of which can be traced back to the 1824 US presidential election, when two local newspapers in North Carolina and Delaware predicted the victory of Andrew Jackson but the sample was local. First national survey was done in 1916 by the magazine, Literary Digest, partly for circulation-raising, by mailing millions of postcards and counting the returns. Of course, this was not very scientific though it accurately predicted the election of Woodrow Wilson.

Since then, opinion polls have grown in extent and complexity with scientific methodology improving the outcome of predictions not only in elections but also in market research. As a result, some of these organisations have become big businesses. For instance, YouGov, an internet-based organisation co-founded by the Iraqi-born British politician Nadim Zahawi, based in London had a revenue of 258 million GBP in 2023.

In Sri Lanka, opinion polls seem to be conducted by only one organisation which, by itself, is a disadvantage, as pooled data from surveys conducted by many are more likely to reflect the true situation. Irrespective of the degree of accuracy, politicians seem to be dependent on the available data which lend explanations to the behaviour of some.

The Institute for Health Policy’s (IHP) Sri Lanka Opinion Tracker Survey has been tracking the voting intentions for the likely candidates for the Presidential election. At one stage the NPP/JVP leader AKD was getting a figure over 50%. This together with some degree of international acceptance made the JVP behave as if they are already in power, leading to some incidents where their true colour was showing.

The comments made by a prominent member of the JVP who claimed that the JVP killed only the riff-raff, raised many questions, in addition to being a total insult to many innocents killed by them including my uncle. Do they have the authority to do so? Do extra-judicial killings continue to be JVP policy? Do they consider anyone who disagrees with them riff-raff? Will they kill them simply because they do not comply like one of my admired teachers, Dr Gladys Jayawardena who was considered riff-raff because she, as the Chairman of the State Pharmaceutical Corporation, arranged to buy drugs cheaper from India? Is it not the height of hypocrisy that AKD is now boasting of his ties to India?

Another big-wig comes with the grand idea of devolving law and order to village level. As stated very strongly, in the editorial “Pledges and reality” (The Island, 20 May) is this what they intend to do: Have JVP kangaroo-courts!

Perhaps, as a result of these incidents AKD’s ratings has dropped to 39%, according to the IHP survey done in April, and Sajith Premadasa’s ratings have increased gradually to match that. Whilst they are level pegging Ranil is far behind at 13%. Is this the reason why Ranil is getting his acolytes to propagate the idea that the best for the country is to extend his tenure by a referendum? He forced the postponement of Local Governments elections by refusing to release funds but he cannot do so for the presidential election for constitutional reasons. He is now looking for loopholes. Has he considered the distinct possibility that the referendum to extend the life of the presidency and the parliament if lost, would double the expenditure?

Unfortunately, this has been an exercise in futility and it would not be surprising if the next survey shows Ranil’s chances dropping even further! Perhaps, the best option available to Ranil is to retire gracefully, taking credit for steadying the economy and saving the country from an anarchic invasion of the parliament, rather than to leave politics in disgrace by coming third in the presidential election. Unless, of course, he is convinced that opinion polls do not matter and what matters is the ballots in the box!

Thoughtfulness or mindfulness?

Published

on

By Prof. Kirthi Tennakone
ktenna@yahoo.co.uk

Thoughtfulness is the quality of being conscious of issues that arise and considering action while seeking explanations. It facilitates finding solutions to problems and judging experiences.

Almost all human accomplishments are consequences of thoughtfulness.

Can you perform day-to-day work efficiently and effectively without being thoughtful? Obviously, no. Are there any major advancements attained without thought and contemplation? Not a single example!

Science and technology, art, music and literary compositions and religion stand conspicuously as products of thought.

Thought could have sinister motives and the only way to eliminate them is through thought itself. Thought could distinguish right from wrong.

Empathy, love, amusement, and expression of sorrow are reflections of thought.

Thought relieves worries by understanding or taking decisive action.

Despite the universal virtue of thoughtfulness, some advocate an idea termed mindfulness, claiming the benefits of nurturing this quality to shape mental wellbeing. The concept is defined as focusing attention to the present moment without judgment. A way of forgetting the worries and calming the mind – a form of meditation. A definition coined in the West to decouple the concept from religion. The attitude could have a temporary advantage as a method of softening negative feelings such as sorrow and anger. However, no man or woman can afford to be non-judgmental all the time. It is incompatible with indispensable thoughtfulness! What is the advantage of diverting attention to one thing without discernment during a few tens of minute’s meditation? The instructors of mindfulness meditation tell you to focus attention on trivial things. Whereas in thoughtfulness, you concentrate the mind on challenging issues. Sometimes arriving at groundbreaking scientific discoveries, solution of mathematical problems or the creation of masterpieces in engineering, art, or literature.

The concept of meditation and mindfulness originated in ancient India around 1000 BCE. Vedic ascetics believed the practice would lead to supernatural powers enabling disclosure of the truth. Failing to meet the said aspiration, notwithstanding so many stories in scripture, is discernable. Otherwise, the world would have been awakened to advancement by ancient Indians before the Greeks. The latter culture emphasized thoughtfulness!

In India, Buddha was the first to deviate from the Vedic philosophy. His teachers, Alara Kalama and Uddaka Ramaputra, were adherents of meditation. Unconvinced of their approach, Buddha concluded a thoughtful analysis of the actualities of life should be the path to realisation. However, in an environment dominated by Vedic tradition, meditation residually persisted when Buddha’s teachings transformed into a religion.

In the early 1970s, a few in the West picked up meditation and mindfulness. We Easterners, who criticize Western ideas all the time, got exalted after seeing something Eastern accepted in the Western circles. Thereafter, Easterners took up the subject more seriously, in the spirit of its definition in the West.

Today, mindfulness has become a marketable commodity – a thriving business spreading worldwide, fueled largely by advertising. There are practice centres, lessons onsite and online, and apps for purchase. Articles written by gurus of the field appear on the web.

What attracts people to mindfulness programmes? Many assume them being stressed and depressed needs to improve their mental capacity. In most instances, these are minor complaints and for understandable reasons, they do not seek mainstream medical interventions but go for exaggeratedly advertised alternatives. Mainstream medical treatments are based on rigorous science and spell out both the pros and cons of the procedure, avoiding overstatement. Whereas the alternative sector makes unsubstantiated claims about the efficacy and effectiveness of the treatment.

Advocates of mindfulness claim the benefits of their prescriptions have been proven scientifically. There are reports (mostly in open-access journals which charge a fee for publication) indicating that authors have found positive aspects of mindfulness or identified reasons correlating the efficacy of such activities. However, they rarely meet standards normally required for unequivocal acceptance. The gold standard of scientific scrutiny is the statistically significant reproducibility of claims.

If a mindfulness guru claims his prescription of meditation cures hypertension, he must record the blood pressure of participants before and after completion of the activity and show the blood pressure of a large percentage has stably dropped and repeat the experiment with different clients. He must also conduct sessions where he adopts another prescription (a placebo) under the same conditions and compares the results. This is not enough, he must request someone else to conduct sessions following his prescription, to rule out the influence of the personality of the instructor.

The laity unaware of the above rigid requirements, accede to purported claims of mindfulness proponents.

A few years ago, an article published and widely cited stated that the practice of mindfulness increases the gray matter density of the brain. A more recent study found there is no such correlation. Popular expositions on the subject do not refer to the latter report. Most mindfulness research published seems to have been conducted intending to prove the benefits of the practice. The hard science demands doing the opposite as well-experiments carried out intending to disprove the claims. You need to be skeptical until things are firmly established.

Despite many efforts diverted to disprove Einstein’s General Theory of Relativity, no contradictions have been found in vain to date, strengthening the validity of the theory. Regarding mindfulness, as it stands, benefits can neither be proved nor disproved, to the gold standard of scientific scrutiny.

Some schools in foreign lands have accommodated mindfulness training programs hoping to develop the mental facility of students and Sri Lanka plans to follow. However, studies also reveal these exercises are ineffective or do more harm than good. Have we investigated this issue before imitation?

Should we force our children to focus attention on one single goal without judgment, even for a moment?

Why not allow young minds to roam wild in their deepest imagination and build castles in the air and encourage them to turn these fantasies into realities by nurturing their thoughtfulness?

Be more thoughtful than mindful?
