Nuclear power plants and precautionary principle

Kudankulam nuclear power plant

By Panduka Karunanayake

While thanking Professor Kirthi Tennakone for his article on nuclear power as an energy option for our country (The Island, May 12), I wish to raise some concerns that were not addressed therein. I don’t have the knowledge of science and a background in the energy sector to be able to answer them myself. But as an ordinary citizen, I think it is a duty to raise these concerns on a matter of such importance.

KT has argued that nuclear energy is reliable, cost-effective and safe (as long as things are running smoothly). While I do not doubt his statements, I have several concerns and they fall into two main categories.

The first category relates to concerns when things are running smoothly. Even if a nuclear power plant has the advantages that he had listed, I worry about two disadvantages. First, where in our country should we site this plant, and what kind of relocation of the population should this require? It may be true that the plant itself would take up only a few square-kilometres, but can ordinary people live right next door to it? Second, how do we dispose of the nuclear waste, where, at what cost and with what consequences? For instance, could radioactive waste leech into underground water tables? How do we monitor that, and what further precautions are necessary to detect and respond to such an event?

I recall an incident more than a decade ago when US environmental scientists detected that radioactive waste from the Cold War era buried deep in the Nevada desert had leached into the water table – but that contaminated water was still 6,000 years from reaching human consumption because the desert is so vast and human beings do not live nearby. (The Nevada desert is 30 million acres, compared to Sri Lanka’s total land area of 16 million acres.)

But the second category of concerns is more important to me. This relates to what might follow if there was a nuclear plant ‘incident’. It probably engenders more speculation and less iron-clad answers, and that might make forming judgements and opinions more fluid and contestable.

KT states that nuclear power plant accidents are very rare and tells us that the Chernobyl and Fukushima incidents are the “only two major mishaps” that have occurred so far. I think that such incidents, whether due to technical failure, mismanagement, human error, sabotage or natural disaster, can and will happen – it’s only a matter of where and when. An important part of planning for something is the planning for such incidents. Although they may be rare, the gravity and consequences of an incident are crucial. The graver the consequences, the more important it is to not dismiss even the rare possibility, and the more important it is to adopt the precautionary principle when forming judgements or making decisions. With this perspective, let me list out some questions.

If such a disaster did happen on Sri Lankan soil at the site that he had identified above, what would be the cost and duration of decontamination? What would be the extent of land, water, air, soil and animal and agricultural produce (including rice, vegetables, meat, fish, eggs and milk) that will have to be given up by us? Can we rely on our regulatory apparatuses to ensure that the food in the market is safe, following such a disaster?

What will happen to tourism? Would the remaining land, air, water, soil, agriculture and animals be enough to sustain the population, or will we have to import our food and even water? Will that be economically feasible, while spending also on decontamination and running without tourism? Who will have access to imported food and water and who will not? What will those without access resort to?

What would be the human health implications to those who survive in terms of disease, birth defects, loss of productivity and cost of treatment? As well as the very likely event of another economic downturn, poverty and malnutrition?

If the radioactive contamination drifts by air to other countries in the region, will we have to pay compensation, and if so, how much?

I think that to face such a “mishap”, a country needs a huge land area, adequate natural resources, enough financial reserves, and good regulatory, administrative and technical apparatuses. I don’t think that the Russian or Japanese examples are contextually appropriate to our setting.

In fact, for several years now, I have been worried about the effects that we ourselves would suffer if the nuclear power plant in South India (which they have sited right at the southernmost part of their huge country, for reasons that are quite understandable). I believe that the wind patterns would probably expose three of our provinces (north-western, north-central and eastern) to radioactive fallout. We should therefore be ready for a nuclear power plant accident even without having one – and we aren’t. That is the sort of ‘planning’ that we are capable of!

The science of love

Published

on

A remarkable increase in marriage proposals in newspapers and the thriving matchmaking outfits in major cities indicate the difficulty in finding the perfect partners. Academics have done much research in interpersonal attraction or love. There was an era when young people were heavily influenced by romantic fiction. They learned how opposites attract and absence makes the heart grow fonder. There was, of course, an old adage: Out of sight out of mind.

Some people find it difficult to fall in love or they simply do not believe in love. They usually go for arranged marriages. Some of them think that love begins after marriage. There is an on-going debate whether love marriages are better than arranged marriages or vice versa. However, modern psychologists have shed some light on the science of love. By understanding it you might be able to find the ideal life partner.

To start with, do not believe that opposites attract. It is purely a myth. If you wish to fall in love, look for someone like you. You may not find them 100 per cent similar to you, but chances are that you will meet someone who is somewhat similar to you. We usually prefer partners who have similar backgrounds, interests, values and beliefs because they validate our own.

Common trait

It is a common trait that we gravitate towards those who are like us physically. The resemblance of spouses has been studied by scientists more than 100 years ago. According to them, physical resemblance is a key factor in falling in love. For instance, if you are a tall person, you are unlikely to fall in love with a short person. Similarly, overweight young people are attracted to similar types. As in everything in life, there may be exceptions. You may have seen some tall men in love with short women.

If you are interested in someone, declare your love in words or gestures. Some people have strong feelings about others but they never make them known. If you fancy someone, make it known. If you remain silent you will miss a great opportunity forever. In fact if someone loves you, you will feel good about yourself. Such feelings will strengthen love. If someone flatters you, be nice to them. It may be the beginning of a great love affair.

Some people like Romeo and Juliet fall in love at first sight. It has been scientifically confirmed that the longer a pair of prospective partners lock eyes upon their first meeting they are very likely to remain lovers. They say eyes have it. If you cannot stay without seeing your partner, you are in love! Whenever you meet your lover, look at their eyes with dilated pupils. Enlarged pupils signal intense arousal.

Body language

If you wish to fall in love, learn something about body language. There are many books written on the subject. The knowledge of body language will help you to understand non-verbal communication easily. It is quite obvious that lovers do not express their love in so many words. Women usually will not say ‘I love you’ except in films. They express their love tacitly with a shy smile or preening their hair in the presence of their lovers.

Allan Pease, author of The Definitive Guide to Body Language says, “What really turn men on are female submission gestures which include exposing vulnerable areas such as the wrists or neck.” Leg twine was something Princess Diana was good at. It involves crossing the legs hooking the upper leg’s foot behind the lower leg’s ankle. She was an expert in the art of love. Men have their own ways. In order to look more dominant than their partners they engage in crotch display with their thumbs hooked in pockets. Michael Jackson always did it.

If you are looking for a partner, be a good-looking guy. Dress well and behave sensibly. If your dress is unclean or crumpled, nobody will take any notice of you. According to sociologists, men usually prefer women with long hair and proper hip measurements. Similarly, women prefer taller and older men because they look nice and can be trusted to raise a family.

Proximity rule

You do not have to travel long distances to find your ideal partner. He or she may be living in your neighbourhood or working at the same office. The proximity rule ensures repeated exposure. Lovers should meet regularly in order to enrich their love. On most occasions we marry a girl or boy living next door. Never compare your partner with your favourite film star. Beauty lies in the eyes of the beholder. Therefore be content with your partner’s physical appearance. Each individual is unique. Never look for another Cleopatra or Romeo. Sometimes you may find that your neighbour’s wife is more beautiful than yours. On such occasions turn to the Bible which says, “Thou shalt not covet thy neighbour’s wife.”

There are many plain Janes and penniless men in society. How are they going to find their partners? If they are warm people, sociable, wise and popular, they too can find partners easily. Partners in a marriage need not be highly educated, but they must be intelligent enough to face life’s problems. Osho compared love to a river always flowing. The very movement is the life of the river. Once it stops it becomes stagnant. Then it is no longer a river. The very word river shows a process, the very sound of it gives you the feeling of movement.

Although we view love as a science today, it has been treated as an art in the past. In fact Erich Fromm wrote The Art of Loving. Science or art, love is a terrific feeling.

Rethinking climate prediction, disasters, and plantation economics in Sri Lanka

For decades, Sri Lanka has interpreted climate through a narrow lens. Rainfall totals, sunshine hours, and surface temperatures dominate forecasts, policy briefings, and disaster warnings. These indicators once served an agrarian island reasonably well. But in an era of intensifying extremes—flash floods, sudden landslides, prolonged dry spells within “normal” monsoons—the question can no longer be avoided: are we measuring the climate correctly, or merely measuring what is easiest to observe?

Across the world, climate science has quietly moved beyond a purely local view of weather. Researchers increasingly recognise that Earth’s climate system is not sealed off from the rest of the universe. Solar activity, upper-atmospheric dynamics, ocean–atmosphere coupling, and geomagnetic disturbances all influence how energy moves through the climate system. These forces do not create rain or drought by themselves, but they shape how weather behaves—its timing, intensity, and spatial concentration.

Sri Lanka’s forecasting framework, however, remains largely grounded in twentieth-century assumptions. It asks how much rain will fall, where it will fall, and over how many days. What it rarely asks is whether the rainfall will arrive as steady saturation or violent cloudbursts; whether soils are already at failure thresholds; or whether larger atmospheric energy patterns are priming the region for extremes. As a result, disasters are repeatedly described as “unexpected,” even when the conditions that produced them were slowly assembling.

This blind spot matters because Sri Lanka is unusually sensitive to climate volatility. The island sits at a crossroads of monsoon systems, bordered by the Indian Ocean and shaped by steep central highlands resting on deeply weathered soils. Its landscapes—especially in plantation regions—have been altered over centuries, reducing natural buffers against hydrological shock. In such a setting, small shifts in atmospheric behaviour can trigger outsized consequences. A few hours of intense rain can undo what months of average rainfall statistics suggest is “normal.”

Nowhere are these consequences more visible than in commercial perennial plantation agriculture. Tea, rubber, coconut, and spice crops are not annual ventures; they are long-term biological investments. A tea bush destroyed by a landslide cannot be replaced in a season. A rubber stand weakened by prolonged waterlogging or drought stress may take years to recover, if it recovers at all. Climate shocks therefore ripple through plantation economics long after floodwaters recede or drought declarations end.

From an investment perspective, this volatility directly undermines key financial metrics. Return on Investment (ROI) becomes unstable as yields fluctuate and recovery costs rise. Benefit–Cost Ratios (BCR) deteriorate when expenditures on drainage, replanting, disease control, and labour increase faster than output. Most critically, Internal Rates of Return (IRR) decline as cash flows become irregular and back-loaded, discouraging long-term capital and raising the cost of financing. Plantation agriculture begins to look less like a stable productive sector and more like a high-risk gamble.

The economic consequences do not stop at balance sheets. Plantation systems are labour-intensive by nature, and when financial margins tighten, wage pressure is the first stress point. Living wage commitments become framed as “unaffordable,” workdays are lost during climate disruptions, and productivity-linked wage models collapse under erratic output. In effect, climate misprediction translates into wage instability, quietly eroding livelihoods without ever appearing in meteorological reports.

This is not an argument for abandoning traditional climate indicators. Rainfall and sunshine still matter. But they are no longer sufficient on their own. Climate today is a system, not a statistic. It is shaped by interactions between the Sun, the atmosphere, the oceans, the land, and the ways humans have modified all three. Ignoring these interactions does not make them disappear; it simply shifts their costs onto farmers, workers, investors, and the public purse.

Sri Lanka’s repeated cycle of surprise disasters, post-event compensation, and stalled reform suggests a deeper problem than bad luck. It points to an outdated model of climate intelligence. Until forecasting frameworks expand beyond local rainfall totals to incorporate broader atmospheric and oceanic drivers—and until those insights are translated into agricultural and economic planning—plantation regions will remain exposed, and wage debates will remain disconnected from their true root causes.

The future of Sri Lanka’s plantations, and the dignity of the workforce that sustains them, depends on a simple shift in perspective: from measuring weather, to understanding systems. Climate is no longer just what falls from the sky. It is what moves through the universe, settles into soils, shapes returns on investment, and ultimately determines whether growth is shared or fragile.

The Way Forward

Sustaining plantation agriculture under today’s climate volatility demands an urgent policy reset. The government must mandate real-world investment appraisals—NPV, IRR, and BCR—through crop research institutes, replacing outdated historical assumptions with current climate, cost, and risk realities. Satellite-based, farm-specific real-time weather stations should be rapidly deployed across plantation regions and integrated with a central server at the Department of Meteorology, enabling precision forecasting, early warnings, and estate-level decision support. Globally proven-to-fail monocropping systems must be phased out through a time-bound transition, replacing them with diversified, mixed-root systems that combine deep-rooted and shallow-rooted species, improving soil structure, water buffering, slope stability, and resilience against prolonged droughts and extreme rainfall.

In parallel, a national plantation insurance framework, linked to green and climate-finance institutions and regulated by the Insurance Regulatory Commission, is essential to protect small and medium perennial growers from systemic climate risk. A Virtual Plantation Bank must be operationalized without delay to finance climate-resilient plantation designs, agroforestry transitions, and productivity gains aligned with national yield targets. The state should set minimum yield and profit benchmarks per hectare, formally recognize 10–50 acre growers as Proprietary Planters, and enable scale through long-term (up to 99-year) leases where state lands are sub-leased to proven operators. Finally, achieving a 4% GDP contribution from plantations requires making modern HRM practices mandatory across the sector, replacing outdated labour systems with people-centric, productivity-linked models that attract, retain, and fairly reward a skilled workforce—because sustainable competitive advantage begins with the right people.

Disasters do not destroy nations; the refusal to change does

Published

Floods caused by Cyclone Ditwah

Sri Lanka has endured both kinds of catastrophe that a nation can face, those caused by nature and those created by human hands. A thirty-year civil war tore apart the social fabric, deepening mistrust between communities and leaving lasting psychological wounds, particularly among those who lived through displacement, loss, and fear. The 2004 tsunami, by contrast, arrived without warning, erasing entire coastal communities within minutes and reminding us of our vulnerability to forces beyond human control.

These two disasters posed the same question in different forms: did we learn, and did we change? After the war ended, did we invest seriously in repairing relationships between Sinhalese and Tamil communities, or did we equate peace with silence and infrastructure alone? Were collective efforts made to heal trauma and restore dignity, or were psychological wounds left to be carried privately, generation after generation? After the tsunami, did we fundamentally rethink how and where we build, how we plan settlements, and how we prepare for future risks, or did we rebuild quickly, gratefully, and then forget?

Years later, as Sri Lanka confronts economic collapse and climate-driven disasters, the uncomfortable truth emerges. we survived these catastrophes, but we did not allow them to transform us. Survival became the goal; change was postponed.

History offers rare moments when societies stand at a crossroads, able either to restore what was lost or to reimagine what could be built on stronger foundations. One such moment occurred in Lisbon in 1755. On 1 November 1755, Lisbon-one of the most prosperous cities in the world, was almost completely erased. A massive earthquake, estimated between magnitude 8.5 and 9.0, was followed by a tsunami and raging fires. Churches collapsed during Mass, tens of thousands died, and the royal court was left stunned. Clergy quickly declared the catastrophe a punishment from God, urging repentance rather than reconstruction.

One man refused to accept paralysis as destiny. Sebastião José de Carvalho e Melo, later known as the Marquês de Pombal, responded with cold clarity. His famous instruction, “Bury the dead and feed the living,” was not heartless; it was revolutionary. While others searched for divine meaning, Pombal focused on human responsibility. Relief efforts were organised immediately, disease was prevented, and plans for rebuilding began almost at once.

Pombal did not seek to restore medieval Lisbon. He saw its narrow streets and crumbling buildings as symbols of an outdated order. Under his leadership, Lisbon was rebuilt with wide avenues, rational urban planning, and some of the world’s earliest earthquake-resistant architecture. Moreover, his vision extended far beyond stone and mortar. He reformed trade, reduced dependence on colonial wealth, encouraged local industries, modernised education, and challenged the long-standing dominance of aristocracy and the Church. Lisbon became a living expression of Enlightenment values, reason, science, and progress.

Back in Sri Lanka, this failure is no longer a matter of opinion. it is documented evidence. An initial assessment by the United Nations Development Programme (UNDP) following Cyclone Ditwah revealed that more than half of those affected by flooding were already living in households facing multiple vulnerabilities before the cyclone struck, including unstable incomes, high debt, and limited capacity to cope with disasters (UNDP, 2025). The disaster did not create poverty; it magnified it. Physical damage was only the visible layer. Beneath it lay deep social and economic fragility, ensuring that for many communities, recovery would be slow, uneven, and uncertain.

The world today offers Sri Lanka another lesson Lisbon understood centuries ago: risk is systemic, and resilience cannot be improvised, it must be planned. Modern climate science shows that weather systems are deeply interconnected; rising ocean temperatures, changing wind patterns, and global emissions influence extreme weather far beyond their points of origin. Floods, landslides, and cyclones affecting Sri Lanka are no longer isolated events, but part of a broader climatic shift. Rebuilding without adapting construction methods, land-use planning, and infrastructure to these realities is not resilience, it is denial. In this context, resilience also depends on Sri Lanka’s willingness to learn from other countries, adopt proven technologies, and collaborate across borders, recognising that effective solutions to global risks cannot be developed in isolation.

A deeper problem is how we respond to disasters: we often explain destruction without seriously asking why it happened or how it could have been prevented. Time and again, devastation is framed through religion, fate, karma, or divine will. While faith can bring comfort in moments of loss, it cannot replace responsibility, foresight, or reform. After major disasters, public attention often focuses on stories of isolated religious statues or buildings that remain undamaged, interpreted as signs of protection or blessing, while far less attention is paid to understanding environmental exposure, construction quality, and settlement planning, the factors that determine survival. Similarly, when a single house survives a landslide, it is often described as a miracle rather than an opportunity to study soil conditions, building practices, and land-use decisions. While such interpretations may provide emotional reassurance, they risk obscuring the scientific understanding needed to reduce future loss.

The lesson from Lisbon is clear: rebuilding a nation requires the courage to question tradition, the discipline to act rationally, and leadership willing to choose long-term progress over short-term comfort. Until Sri Lanka learns to rebuild not only roads and buildings, but relationships, institutions, and ways of thinking, we will remain a country trapped in recovery, never truly reborn.
