Are we eliminating botany in our high school syllabi?

A troubling trend with global echoes and local implications

At a time when biodiversity loss, climate change, and food insecurity dominate international headlines, and sustainable development are at the forefront of global priorities, it seems paradoxical that the systematic study of plants — botany — is quietly disappearing from high school syllabi across the world. Both globally and here in Sri Lanka, botany is gradually being absorbed into broader biology curricula, or worse, omitted altogether, raising serious concerns for the future. This shift is not just a curiosity of education policy; it is shaping a generation that is alarmingly disconnected from the very organisms that sustain life on Earth.

Recent research underscores this concern. A 2023 study published in BMC Biology Education found that only 9% of secondary school biology exam questions across ten countries pertained to plants. Meanwhile, a meta-analysis in New Phytologist (2022) documented declining enrolments in botany and plant taxonomy courses at universities globally, linking it to reduced curricular emphasis in schools.

The global erosion of plant science education

Around the world, educators and scientists have sounded the alarm over what is sometimes called “plant blindness” — the tendency of people, especially urban populations, to overlook plants in favour of more charismatic fauna. Studies in the US, UK, and Australia have documented a steady reduction in botany-specific content in school syllabi. Biology courses overwhelmingly favour human physiology, genetics, and zoology, often relegating plants to a few cursory chapters.

For instance, a 2019 survey of secondary school biology curricula across several OECD (Organisation for Economic Co-operation and Development) countries found that less than 15% of biology syllabus time was dedicated to plant-related topics. Universities report that fewer students choose botany majors, leading to shortages of trained botanists — ironically, just as we need them most to tackle agricultural resilience, forest restoration, and conservation.

The Sri Lankan story: from colonial botany to modern neglect

Sri Lanka’s experience mirrors this global trend but also has a unique historical arc. During the British colonial period, botany was a prominent part of school education. Many early syllabi (e.g. 1902 & 1921 Ceylon Education Codes) included separate subjects on botany and plant classification, reflecting both colonial interests in plantation crops and the global push for natural history education. Students examined local flora, collected specimens, and engaged with plant taxonomy.

By the 1990s, however, reforms gradually merged botany and zoology into a single subject: general biology. While intended to modernise science education, this merger drastically curtailed the depth of plant studies. A glance at our own G.C.E. Ordinary Level and Advanced Level biology syllabi reveals a disproportionate emphasis on human biology. Today, at G.C.E. A/L level, botany is reduced to a handful of chapters on plant histology, physiology, and reproduction, with scant attention to Sri Lanka’s astonishing plant diversity.

Consequences at university level: a shrinking knowledge base

This shift is evident in our undergraduates. A 2021 survey conducted among first-year biology majors at two Sri Lankan universities revealed that fewer than 15% could identify even five common endemic plant species. Their understanding of fundamental plant taxonomy — once the backbone of biological education — was described by lecturers as “abysmal.”

The consequences ripple into higher education and research. Universities now struggle to fill botany specialisations, impacting critical fields such as conservation biology, plant systematics, and herbal pharmacognosy. Ironically, this occurs as Sri Lanka grapples with forest degradation and the need to sustainably harness its rich endemic flora.

Botany as a stand-alone subject, once offered alongside zoology, has all but disappeared from school syllabi. At A/L level, botany is merely a component within the broader biology syllabus. Consequently, fewer students develop a deep interest or expertise in plant sciences before entering university, affecting enrolment in specialising Honours Degrees in botany, plant biotechnology, and related fields.

The global plant blindness problem

This is not a uniquely Sri Lankan failing. International scholars warn of “plant blindness,” a term coined by Wandersee & Schussler, describing how humans fail to notice plants in their environment and undervalue their importance. A 2022 paper in Science Advances reported that biology textbooks worldwide devote less than 10% of pages to plants, despite plants constituting over 80% of Earth’s biomass.

Why does it matter?

Plants underpin life on Earth. They produce oxygen, regulate climate, stabilise soils, provide food, medicine, clothing, and shelter. In Sri Lanka, where over 1,400 plant species are endemic and traditional knowledge of medicinal plants is rich, understanding our flora is not merely academic — it is part of our cultural and economic heritage. Moreover, traditional knowledge systems, from Ayurveda to local agroforestry practices, hinge on a deep familiarity with plants. When the next generation is not taught to recognise even the common species around them, we sever links to this ecological and cultural inheritance.

Neglecting plant science education threatens our ability to conserve biodiversity, manage ecosystems, and innovate in agriculture and herbal industries. With climate variability already affecting tea, coconut, and rice yields, we need more — not fewer — young minds trained in plant science.

A call to restore balance

Internationally, there is growing recognition of this gap. Organizations such as the Botanical Society of America and campaigns like “Plant Love Stories” work to re-engage young people with plants. Initiatives such as the “Plants in Our World” curriculum in Europe and botanic garden outreach programs aim to restore balance. Some countries are revising curricula to integrate more ecological and plant-based studies.

Sri Lanka too must consider revising syllabi to reinstate rigorous botany components — from plant anatomy and systematics to field-based identification exercises. Reintroducing school herbaria, medicinal plant gardens, local flora surveys, and digital plant ID tools could stimulate interest. Universities could partner with schools for hands-on taxonomy workshops, reconnecting students with the extraordinary diversity outside their classroom doors.

In conclusion

As we confront environmental challenges that are inherently tied to plants — from deforestation to food insecurity — we cannot afford a generation indifferent to botany. Addressing this educational blind spot is essential not only for scientific advancement but for safeguarding our ecosystems and cultural legacy.

If we truly aim for a sustainable future, it is time to bring botany back to the centre stage of our classrooms, both globally and right here in Sri Lanka.

Ranwala crash: Govt. lays bare its true face

Published

on

The NPP government is apparently sinking into a pit dug by the one of its members, ‘Dr’ Asoka Ranwala; perhaps a golden pit (Ran Wala) staying true to his name! Some may accuse me of being unpatriotic by criticising a government facing the uphill task of rebuilding the country after an unprecedented catastrophe. Whilst respecting their sentiment, I cannot help but point out that it is the totally unwarranted actions of the government that is earning much warranted criticism, as well stated in the editorial “Smell of Power” (The Island, 15 December). Cartoonist Jeffrey, in his brilliance, has gone a step further by depicting Asoka Ranwala as a giant tsunami wave rushing to engulf the tiny NPP house in the shore, AKD is trying to protect. (The Island, 18 December).

The fact that Asoka Ranwala is very important to the JVP, for whatever reason, became evident when he was elected the Speaker of Parliament despite his lack of any parliamentary experience. When questions were raised about his doctorate in Parliament, Ranwala fiercely defended his position, ably supported by fellow MPs. When the Opposition kept on piling pressure, producing evidence to the contrary, Ranwala stepped aside, claiming that he had misplaced the certificate but would stage a comeback, once found. A year has passed and he is yet to procure a copy of the certificate, or even a confirmatory letter from the Japanese university!

The fact that AKD did not ask Ranwala to give up his parliamentary seat, a decision he may well be regretting now following recent events, shows that either AKD is not a strong leader who can be trusted to translate his words to action or that Ranwala is too important to be got rid of. In fact, AKD should have put his foot down, as it was revealed that Ranwala was a hypocrite, even if not a liar. Ranwala led the campaign to dismantle the private medical school set up by Dr Neville Fernando, which was earning foreign exchange for the country by recruiting foreign students, in addition to saving the outflow of funds for educating Sri Lankan medical graduates abroad. He headed the organisation of parents of state medical students, claiming that they would be adversely affected, and some of the photographs of the protests he led refer to him as Professor Ranwala! Whilst leading the battle against private medical education, Ranwala claims to have obtained his PhD from a private university in Japan. Is this not the height of hypocrisy?

The recent road traffic accident he was involved in would have been inconsequential had Ranwala been decent enough to leave his parliamentary seat or, at least, being humble enough to offer an apology for his exaggerated academic qualifications. After all, he is not the only person to have been caught in the act of embellishing a CV. As far as the road traffic accident is concerned, too, it may not be his entire responsibility. Considering the chaotic traffic, in and around Colombo, coupled with awful driving standards dictated by lack of patience and consideration, it is a surprise that more accidents do not happen in Sri Lanka. Following the accident, may be to exonerate from the first count, a campaign was launched by NPP supporters stating that a man should be judged on his achievements, not qualifications, further implying that he does not have the certificate because he got it in a different name!

What went wrong was not the accident, but the way it was handled. Onlookers claim that Ranwala was smelling of alcohol but there is no proof yet. He could have admitted it even if he had taken any alcohol, which many do and continue to drive in Sri Lanka. After all, the Secretary to the Ministry overseeing the Police was able to get the charge dropped after causing multiple accidents while driving under the influence of liquor! He, with another former police officer, sensing the way the wind was blowing formed a retired police collective to support the NPP and were adequately rewarded by being given top jobs, despite a cloud hanging over them of neglect of duty during the Easter Sunday attacks. This naïve political act brought the integrity of the police into question. The way the police behaved after Ranwala’s accident confirmed the fears in the minds of right-thinking Sri Lankans.

In the euphoria of the success of a party promising a new dawn, unfortunately, many political commentators kept silent but it is becoming pretty obvious that most are awaking to the reality of a false dawn. It could not have come at a worse time for the NPP: in spite of the initial failures to act on the warnings regarding the devastating effects of Ditwah, the government was making good progress in sorting problems out, when Ranwala met with an accident.

The excuses given by the police for not doing a breathalyser test, or blood alcohol levels, promptly, are simply pathetic. Half-life of alcohol is around 4-5 hours and unless Ranwala was dead drunk, it is extremely unlikely any significant amounts of alcohol would be detected in a blood sample taken after 24 hours. Maybe the knowledge of this that made government Spokesmen to claim boldly that proper action would be taken irrespective of the position held. Now that the Government Analyst has not found any alcohol in the blood, no action is needed! Instead, the government seems to have got the IGP to investigate the police. Would any police officers suffer for doing a favour to the government? That is the million-dollar question!

Unfortunately, all this woke up a sleeping giant; a problem that the government hoped would be solved by the passage of time. If the government is hoping that the dishonesty of one of its prominent members would be forgotten with the passage of time, it will be in for a rude shock. When questioned by journalists repeated, the Cabinet spokesman had to say action would be taken if the claim of the doctorate was false. However, he added that the party has not decided what that action would be! What about the promise to rid Parliament of crooks?

It is now clear that the NPP government is not any different from the predecessors and that Sri Lankan voters are forced to contend with yet another false dawn!

Ceylon pot tea: redefining value, sustainability and future of global tea

Published

on

The international tea industry is experiencing one of the most difficult periods in its history. Producers worldwide are caught in a paradox: tea must be made “cheaper than water” to stay competitive, yet this very race to the bottom erodes profitability, weakens supply chains, and drives away the most talented professionals whose expertise is essential for innovation. At the heart of this crisis lies the structure of commodity tea pricing. Although the auction system has served the world for over a century, it has clear limitations. It rewards volume rather than innovation, penalises differentiation, and leaves little room for value-added product development.

Sri Lanka, one of the world’s finest tea origins, feels this pressure more intensely than most. The industry’s traditional reliance on auctions prevents it from accessing the full premium that its authentic climate, terroir, and craftsmanship deserve. The solution is not to dismantle auctions—because they maintain transparency and global trust—but to evolve beyond them. For tea to thrive again, Ceylon Tea must enter the product market, where brand value, wellness benefits, and consumer experience define price—not weight.

Sri Lanka’s Unique Comparative Advantage

Sri Lanka possesses both competitive and comparative advantage unmatched by any other tea-producing nation. One of the least-discussed scientific advantages is its low gravitational pull, enabling the tea plant to circulate nutrients differently and produce a uniquely delicate, flavour-rich leaf. This natural phenomenon, combined with diverse microclimates, gives Sri Lankan tea extraordinary antioxidant density, rich polyphenols, and a full sensory profile representative of the land and its people.

However, this advantage is undermined by weaknesses in basic agronomy. Most estates do not use soil augers, and soil sampling is often inconsistent or unscientific. This leads to overuse of artificial fertilizer, underinvestment in regenerative practices, and weak soil organic matter (SOM). Without scientific soil management, even a world-class tea origin can lose its competitive edge. Encouragingly, discussions are already underway with the Assistant Indian High Commissioner in Kandy to explore sourcing 3,000 scientifically engineered soil augers for Sri Lanka’s perennial agriculture sector—a transformative step toward soil intelligence and sustainable input management.

Improving SOM, moderating fertilizer misuse, and systematically diagnosing soil nutrient deficiencies represent true sustainability—not cosmetic commitments. Plantation agriculture, which supports over one million Sri Lankan livelihoods, depends on this shift.

The Real Economic Challenge: Price per Kilogram

The most urgent sustainability problem is not climate change or labour cost—it is the low price per kilogram Sri Lanka receives for its tea. Nearly 20% of the tea leaf becomes “refuse tea”, a stigmatized fraction that still contains antioxidants and valuable nutrients but fetches a low price at auctions. The system inherently undervalues almost a fifth of the raw material.

A rational solution is to market the entire tea leaf without discrimination, transforming every component—tender leaf, mature leaf, fiber, and fines—into a premium product with a minimum retail value of USD 15 per kilogram. Achieving this requires product innovation, not further cost reduction.

Ceylon Pot Tea: A Transformative Opportunity

Ceylon Pot Tea emerges as a comprehensive solution capable of addressing long-standing structural issues in Sri Lanka’s tea industry. Unlike traditional tea grades, Pot Tea compresses the entire fired dhool into a high-value cube, similar to the global success of soup cubes. Every part of the leaf is represented, unlocking maximum biochemical utilisation and offering consumers a fuller taste profile with richer aroma, deeper colour, and higher antioxidant content.

Pot Tea is perfectly aligned with the health and wellness market, one of the fastest-growing global consumer segments. As an Herbal Medicinal Beverage (HMB), it captures the complete phytonutritional matrix of the tea leaf, including polyphenols, catechins, and climate-influenced compounds unique to Ceylon. The product also offers storytelling power: every cube reflects the terroir, the gentle fingers that plucked the leaf, and the mystical nature of tea grown in a land with unusually low gravitational intensity.

Already, international partners—particularly in Russia—and domestic innovators have expressed enthusiasm. Pot Tea aligns closely with the policy direction set by the Hon. Samantha Vidyarathne and the NPP Government, especially the national goal of achieving 400 million Kgs of national annual production per year by unlocking new value chains and premium product categories.

Why Immediate Government Intervention Is Necessary

For Sri Lanka to fully benefit from Ceylon Pot Tea and other modernized value chains, the government must urgently introduce:

1. Minimum Yield Benchmarks per hectare (3-year targets) for all perennial crops, informed by scientific investment appraisals.

2. A classification shift from “plantations” to land-based investment enterprises, recognising the capital-intensive, long-term nature of tea cultivation.

3. Incentives for soil testing, soil auger adoption, and SOM improvement programs.

4. Support for value-added tea manufacturing and export diversification.

These steps would create an enabling environment for Pot Tea to scale rapidly and position Sri Lanka as the world’s leading innovator in tea-based wellness products.

Way Forward: Positioning Ceylon Pot Tea for Global Leadership

The path ahead requires a coordinated national and industry-level effort. Sri Lanka must shift from simply producing tea to designing tea experiences. Ceylon Pot Tea can lead this transformation if:

1. Branding and Certification Are Strengthened

CCT (Ceylon Certified Tea) standards must be universally adopted to guarantee purity, origin authenticity, and ethical production practices.

2. Research, Soil Science & Agronomy Are Modernized

With scientific soil audits, optimized fertigation, and regenerative agriculture, Sri Lanka can unlock higher yields and stronger biochemical profiles in its leaf.

3. A Global Wellness Narrative Is Created

Position Pot Tea as a nutritional, therapeutic, anti-aging, and calming beverage suited for the modern lifestyle.

4. Export Market Activation Begins Immediately

Pilot shipments, influencer partnerships, and cross-border digital campaigns should begin with Russia, the Middle East, Japan, and premium EU markets.

5. Producers Are Incentivised to Convert Dhools to Cubes

This ensures minimal waste, improved margins, and equitable value distribution across the supply chain.

Conclusion: A New Dawn for Ceylon Tea

Ceylon Pot Tea offers Sri Lanka a rare chance to pivot from a commodity-driven past to a premium, wellness-oriented, high-margin future. It aligns economic sustainability with environmental responsibility. It empowers estate communities with modern agronomy. And most importantly, it transforms every gram of the tea leaf into value—finally rewarding the land, the planter, and the plucker.

If implemented with vision and urgency, Ceylon Pot Tea will not only revitalise an industry under immense pressure but also secure Sri Lanka’s place as the world’s most innovative and scientifically grounded tea nation.

Lakshman Balasuriya – simply a top-class human being

Published

on

It is with deep sorrow that I share the passing of one of my dearests and most trusted friends of many years, Lakshman Balasuriya. He left us on Sunday morning, and with him went a part of my own life. The emptiness he leaves behind is immense, and I struggle to find words that can carry its weight.

Lakshman was not simply a friend. He was a brother to me. We shared a bond built on mutual respect, quiet understanding, and unwavering trust. These things are rare in life, and for that reason they are precious beyond measure. I try to remind myself that I was privileged to spend the final hours of his life with him, but even that thought cannot soften the ache of his sudden and significant absence.

Not too long ago, our families were on holiday together. Lakshman and Janine returned to Sri Lanka early. The rest of the holiday felt a bit empty without Lakshman’s daily presence. I cannot fathom how different life itself will be from now on.

He was gentle and a giant in every sense of the word. A deeply civilized man, refined in taste, gracious in manner, and extraordinarily humble. His humility was second to none, and yet it was never a weakness. It was strength, expressed through kindness, warmth, and dignity. He carried himself with quiet class and had a way of making everyone around him feel at ease.

Lakshman had a very dry, almost deadpan, sense of humor. It was the kind of humor that would catch you off guard, delivered with too straight a face to be certain he was joking, but it could lighten the darkest of conversations. He had a disdain for negativity of any kind. He preferred to look forward, to see possibilities rather than obstacles.

He was exceptionally meticulous and had a particular gift for identifying talent. Once he hired someone, he made sure they were cared for in unimaginable ways. He provided every resource needed for success, and then, with complete trust, granted them independence and autonomy. His staff were not simply employees to him. They were family. He took immense pride in them, and his forward-thinking optimism created an environment of extraordinary positivity and a passion to deliver results and do the right thing.

Lakshman was also a proud family man. He spoke often, and with great pride, about his children, grandchildren, nephews, and nieces. His joy in their achievements was boundless. He was a proud father, grandfather, and uncle, and his devotion to his family reflected the same loyalty he extended to his colleagues and friends.

Whether it was family, staff, or anyone he deemed deserving, Lakshman stood by them unconditionally in times of crisis. He would not let go until victory was secured. That was his way. He was a uniquely kind soul through and through.

Our bond was close. Whenever I arrived in Sri Lanka, it became an unspoken ritual that we would meet at least twice. The first would be on the day of my arrival, and then again on the day I left. It was our custom, and one I cherished deeply. We met regularly, and we spoke almost daily. He was simply a top-class human being. We were friends. We were brothers. His passing has devastated me.

Today I understood fully the true meaning of the phrase ‘priyehi vippaogo dukkho’ — (ප්‍රියෙහි විප්පයෝගෝ දුක්ඛෝපෝ) ‘separation from those who are beloved is sorrowful.’

My thoughts and prayers are with Janine, Amanthi, and Keshav during this time of profound loss. Lakshman leaves behind indelible memories, as well as a legacy of decency, loyalty, and quiet strength. All of us who were fortunate to know him will hold that legacy close to our hearts.

If Lakshman’s life could leave us with just one lesson, that lesson would be this. True greatness is not measured in titles or possessions, but in the way one treats others: with humility, with loyalty, with kindness that does not falter in times of crisis. Lakshman showed us that to stand by someone, to believe in them, and to lift them up when they falter, is the highest of callings, and it was a calling he never failed to honour.

Rest well, my dear friend.
