Profile
Publis is a household name in Sri Lanka as a chef, author, TV personality, and to many, a national treasure. He joined Mount Lavinia Hotel in 1956 as a kitchen labourer. In the early-1970s he was trained by the Hyatt Corporation in USA, who managed the hotel at that time. Publis was promoted as the Executive Chef in 1984, and then promoted as the Director Culinary Affairs & Promotions in 2003, a position he has held for 20 years. During his 67-year long career at Mount Lavinia Hotel, he also did a stint in the Maldives and was responsible for organizing numerous Sri Lankan food festivals and promotions in 33 countries.
I first met Publis Silva in 1972 at the Mount Lavinia Hyatt Hotel, when he was the Assistant Chef, and I was a Trainee Waiter. The next time I met him was in 1990 and we worked closely as the Executive Chef and the General Manager. We then co-wrote a book which was the maiden attempt in book publishing by each of us. After I left Sri Lanka in 1994 we kept in touch, and he made sure that I received a signed copy of each of his books. Today I am his proudest fan.
First Impressions in 1972
By early 1970s Mount Lavinia Hotel (MLH) became the first ever hotel in Ceylon to get an international brand name. Hyatt Hotels Corporation in USA managed MLH. At that time, to graduate from the Ceylon Hotel School (CHS), each student had to do two mandatory co-op placements or in-service periods. Four of my CHS batchmates and I were fortunate to be allocated to MLH for our first in-service in 1972/1973 tourist season.
After the American General Manager from Hyatt corporation, Robert McFadden, met with us on our first day, we were introduced to a few key members of the hotel team, including Publis Silva, who was the Assistant Chef of MLH at that time. He was in his mid-thirties, and I was in my late teens.
My first impression of Publis was special. By then he had worked in the MLH kitchens for 16 years and gradually had risen to the second in command position of the kitchen department. He had also undergone training with three European Executive Chefs sent to MLH by Hyatt.
After the departure of those expatriate chefs, Just before the 1972/1973 tourist season, the hotel had appointed an Acting Executive Chef, a young Sri Lankan from a prominent family in Colombo, who was trained by Publis. I watched how Publis treated this young chef with respect and fully supporting him. Publis is a professional who always respected superiors, irrespective of their level of experience or knowledge.
Christmas of 1972
I remember Publis leading the kitchen brigade in preparing the Christmas Eve dinner in 1972. I sought Chef Publis’s help in understanding some of the dishes I was not familiar with. Despite being very busy that day Publis went into detailed explanations in Sinhala. He wanted us to be well-informed Trainee Waiters. With the additional knowledge I gained by talking with Publis, I managed to earn some extra tips that evening. He was always very helpful and friendly.
Working in the same team in 1990
Eighteen years later In 1990, when I returned to MLH as the General Manager, Publis worked on my team as the Executive Chef. I quickly appreciated that Publis is a great asset to the hotel. Whatever task I delegated to him was done promptly and efficiently. His knowledge of the history of MLH, and the culture of the company were useful to me in settling down in my new and the last job position in Sri Lanka.
Publis was the first to come to work every day and did the longest shift, among all managers. He hardly took any off days, and never needed any sick leave. He was always healthy and fit as a fiddle. MLH was and is his temple. When we worked together on new à la carte menus, I realized that Publis was also open to new suggestions. When the owners of MLH agreed to my suggestion to establish an International Hotel School (IHS) within MLH, Publis became a big supporter of my vision.
Establishing IHS in 1991
IHS was launched with a bang in 1991. It was an immediate success with five international accreditations and pathways and students from five countries. I worked as the Managing Director of IHS and Publis worked as the Adviser in Culinary courses. We also established a Program Advisory Committee with experts from ten countries and introduced for the first time in Sri Lanka, ‘Hotel Administration’ seminars for senior managers. At the end of the 22-week culinary program of IHS, Publis choreographed a classical menu with 13 dishes, cooked, and served by IHS students. We invited all the Executive Chefs of five-star hotels in Colombo for this meal.
Getting into Book Publishing in 1992
One day Publis came to me with a suggestion for a new food promotion. “Sir, how about doing a mushroom promotion? We have a wide variety of mushrooms in Sri Lanka, but unknown to many.” After a brief discussion, I was very impressed with Publis’s wide knowledge of the subject. I learnt a lot from him about mushrooms. “OK, Chef. Let’s move forward with your suggestion. Can you produce a small booklet about mushrooms?” I planted a seed in his mind. Within a few days he found a sponsor to print the booklet. Publis was always prompt in making things happen.
The ‘Mushroom Week’ of MLH was held from 24th to 30th April 1991, in association with the Ceylon Tourist Board, the Mushroom Development and Training Centre and Export Development Board. The booklet compiled by Publis was sold for US$ 2.50 a copy. That was the beginning of the most outstanding journey of writing and publishing books on Sri Lankan gastronomy, by the longest-standing Sri Lanka chef.
After the success of the mushroom promotion, I wanted to explore other possibilities to showcase Publis’s amazing research and knowledge about local ingredients and traditional dishes. He was doing in-depth research on dishes specifically prepared for the royal families of the Kandyan kingdom, prior to 1815. However, when I suggested that he should author a ground-breaking Sri Lankan cookbook, Publis declined citing his lack of knowledge of the English language. I said to him, “why don’t you write the book in Sinhala?”, but he was too shy to undertake such a project.
I did not give up. I twisted his arm occasionally and gently, but it took a year before he agreed, on one condition. That was: I must work as his co-author. I agreed, but he did most of the work. My key contributions were writing a short introduction and finding a publisher. In 1992 we published ‘Sinhala Bojana’ in Sinhala and in 1993 we published ‘Traditional Sri Lankan Food’ in English.
After that, I left Sri Lanka, and we did not collaborate for scholarly publications, but proceeded with our own subjects of interest. Publis continued in creating the greatest volume of books dedicated to Sri Lankan food. I focused mainly on international hospitality management, tourism, and innovation. With those two books, both Publis and I commenced a 31-year journey of book writing and publishing, cumulatively totalling 47 books, so far…
Best Manager in 1993
The Chairman of MLH, Mr. Sanath Ukwatte and I decided to select the ‘Best Manager’ of the hotel in early 1993. Being such a generous person, the Chairman decided to present a car to the winner. We had an excellent team at MLH, but our choice was easy. We picked Publis and rewarded him with the prize of a car.
After my three-year expatriate contract, I left MLH in December 1993 and a few months later I left Sri Lanka for good to focus on my international career. On my last day at MLH, while my family was packing our bags to leave, Publis called me. When he said, “Sir, may I see you with our farewell present?”, I told him, “Chef, the management team already presented me with presents, last evening during the farewell party.” “No Sir, I want to come with my senior team of Chefs to give you something special.” Within a few minutes Publis and his team of 12 Sous Chefs and Chef de Partie came to my apartment at MLH and presented me with an engraved plaque.
A Loyal and Grateful Friend from 1994 to 2023
After 1994 I have stayed at MLH many times as a guest during family holidays, doing consulting assignments, presenting leadership development seminars, and doing a few IHS re-structuring projects. I chose MLH as the venue for two of my most important life events – the home coming wedding reception for my wife in 1999, and my 50th birthday party in 2003. On those two occasions, I never looked at the menu. When Publis asked me what I want in the menu I simply told him, “You decide on the menu, Chef. Anything good for you is good for me.” On both these special occasions, just as I expected, Chef Publis exceeded my expectations.
When it comes to memorable and magical events, there is no better venue than MLH, and no better Chef than Publis. MLH has been my home away from home during the last 30 years. Meanwhile, Publis made sure that I received a signed copy of each of his books. Every time he was generous with his appreciation and thanks for getting him to write and publish in 1992. Despite my repeated reminders to him that I don’t deserve such praise, Publis has been disobedient in that regard.
On April 20, 2023, while on a seven-week holiday in Sri Lanka I received a message through a friend that Dr. Publis Silva wants to see me before my departure. When he heard that I ws being hosted to dinner at Ellen’s Place – an inn in Colombo eight, by a few hotelier friends, Publis showed up early. Unfortunately, my previous engagement was delayed by an hour, and poor Publis stayed on patiently in spite of his family having a religious ceremony at his house on the same evening.
After a brief chat he presented me with a signed copy of his latest book: ‘MAHASUPAWAMSAYA: The Great Chronicle of Sri Lankan Culinary Art’. I glance through the book to find that it has a total of 1,074 pages! Chef Publis never ceased to amaze me!
I was deeply touched with the message that he hand wrote on the front page of the book he presented to me. It said: “This is presented to you, who supported me and encouraged me to write books.” For over 50 years, the privilege has been mine to get many opportunities to associate with the greatest Sri Lankan Chef, who is indeed a National Treasure.
Questions and Answers
After I returned to Canada, soon after our last meeting in 2023, I sent the following ten questions to Deshabandu Dr. T. Publis Silva:
Q: Out of all the places you have visited in Sri Lanka and overseas, what is your favourite and most interesting place?
A: Mount Lavinia Hotel and I are inseparable. Hence, I can proudly say that my favourite place out of every country and city I have ever been to is, Mount Lavinia (Galkissa).
Q: You have inspired generations of culinary professionals. Thinking of the other side of the coin, in your career, who inspired you most?
A: In 1950s, the first à la carte restaurant in Ceylon was opened at MLH and its kitchen was developed and managed by Bass (Head Cook) R. K. M. Silva.He was a real inspiration for me and taught me a lot of valuable lessons. After his passing, to pay my respects, I created a dish named after him called “Seer RKM.” and placed it in menus across the hotel, as well as in my books, especially the Sinhalese Practical Cookery book which was used in many culinary schools and institutions across Sri Lanka.
Q: At the present time, apart from cooking, researching, and writing, what is your key passion in life?
A: To make food that is medicine is my current key passion and goal in life. This mainly includes using the abundant varieties of fruits, vegetables, legumes, seeds, cereals, and beans to dishes which are brimming with health properties. To add into it, the art of putting love and attention into the food we make while being mindful in the whole cooking process ensures we keep the maximum nutrition value of the food while preserving the flavour and the aroma of the food.
In the modern world, non-contagious diseases such as diabetes and cancer are more prevalent and deadly and eating the right type of food can ensure we can prevent or control these diseases.
Q: Can you tell our readers about your interesting adventures before joining MLH in 1956?
A: As a kid of six years old, I used to go to the beach in Ratgama with my friends and the entire beach was ours to explore. I remember we used to pluck coconuts from the trees, husk and crack the shells and then eat the kernel. One day when a piece of kernel fell in the sand, I washed it with sea water. When I ate it I experienced a better taste. This was one of my initial curiosities into the culinary world.
When I was around 20 years old, without a job and after marriage, I used to push carts in Colombo to earn a living. My passengers usually head for the market to sell produce and usually there were leftovers. I used to pick them up and then cook dishes from those.
I remember the first time I used a leftover karawala (dry salted fish) bone in a vegetable curry, the flavour made me feel like I was in heaven and to-date, that was the best food I remember having experienced. These are a few of my stories about the hardships I faced and how I developed a passion for cooking.
Q: In 1970 when MLH became the first hotel in Sri Lanka to be managed by an international hotel chain, what did you learn from the Hyatt Corporation, USA?
A: Hyatt Corporation brought in international chefs and I with all our MLH kitchen staff learned a lot from them. I especially learned about butchery and meat from French, German and Swiss chefs and I respect them for further igniting my passion to research about all kinds of food.
Q: Can you give the readers some numbers from your 67-year long career in culinary arts – total number of books, TV shows, food festivals, weddings catered for (including BMICH) etc.?
A: I have written 20 books, attended a countless number of TV shows, and I remember celebrating the 10,000th wedding catered when Dr. Chandana Jayawardena was the General Manager of MLH. In 1992, as the long-standing catering partner of BMICH – national convention centre, MLH did the catering for the largest wedding to be held in Sri Lanka. We prepared and served 2,400 invitees a sit-down Biriyani dinner within 90-minutes. I must mention that Dr. Chandana Jayawardena was also the person who pushed me into writing more books and my first book was written along with his collaboration. I have also visited 33 countries to promote Sri Lankan food and culture.
Q: You have recorded numerous achievements, including two Guinness World Records, an honorary doctorate, and the national award of Deshabandu. What do you consider as your greatest achievement during the last 77 years?
A: The greatest achievement for me was the Guiness World Record for the world’s largest milk rice ever made. It contained 1000kg of rice and 2000kg of coconuts. During that huge undertaking, it felt like I was the conductor of a symphony orchestra with 120 chefs. They were ready to obey each command, I told them when to add the rice, when to add the milk, when to add the water, when to lower the fire, and finally, the end-product which was 62 feet long and five feet wide was a world record breaking milk rice with a consistent flavour and each piece was enjoyed by those who attended to witness the world record.
Q: Your book MAHASUPAVANSHAYA, has over 1,000 pages and you led a large team of researchers in producing this book. Tell our readers more about that remarkable process ?
A: It took me and my team over 30 years to complete the book, we went across Sri Lanka gathering a vast volume of information and our research took us to some parts in Africa as well. Professors and students from Sri Jayewardenepura University helped me a lot along with a team of 12 chefs from MLH. During my research, while learning about the history of culinary arts in Sri Lanka, I learned that during the time of King Dutugamunu, they used a Stone Oruwa (a stone boat) filled it with water, filled it with heated rocks and that brought the water to a heated temperature, which ultimately made the Stone Oruwa act as a chafing dish to keep any food containers placed inside hot. This was the first recorded usage of a chafing dish in the world.
Q: What does a normal day of the Director Culinary Affairs and Promotions of MLH, look like?
A: The first thing I do when I arrive at my office in the morning is to search for new innovations in the culinary field. I keep myself as a student and learn new things every day. I ensure that anything I learn I teach to the next generation and then search for new innovations again. This cycle encapsulates my normal day as the Director of Culinary Affairs and Promotions. For example, my thinking of culinary innovation led me to learn that, if we take the Kos Tree (Jak Fruit Tree), there are abundant uses we have, and each piece of the entire Kos Tree can be used in some culinary way.
Q: What is your advice to young chefs who dream of having a long career in culinary arts?
A: In the world, I believe that the best thing someone can learn is to cook, I ask of the entire younger generation to learn cooking as I believe that if anyone learns about cooking, it will be one of the most important and useful skills acquired in life.
Next week, 3Ps will feature a university professor who is also a leader in tourism in Sri Lanka…

Making ‘Sinhala Studies’ globally relevant
On 8 January 2026, I delivered a talk at an event at the University of Colombo marking the retirement of my longtime friend and former Professor of Sinhala, Ananda Tissa Kumara and his appointment as Emeritus Professor of Sinhala in that university. What I said has much to do with decolonising social sciences and humanities and the contributions countries like ours can make to the global discourses of knowledge in these broad disciplines. I have previously discussed these issues in this column, including in my essay, ‘Does Sri Lanka Contribute to the Global Intellectual Expansion of Social Sciences and Humanities?’ published on 29 October 2025 and ‘Can Asians Think? Towards Decolonising Social Sciences and Humanities’ published on 31 December 2025.
At the recent talk, I posed a question that relates directly to what I have raised earlier but drew from a specific type of knowledge scholars like Prof Ananda Tissa Kumara have produced over a lifetime about our cultural worlds. I do not refer to their published work on Sinhala, Pali and Sanskrit languages, their histories or grammars; instead, their writing on various aspects of Sinhala culture. Erudite scholars familiar with Tamil sources have written extensively on Tamil culture in this same manner, which I will not refer to here.
To elaborate, let me refer to a several essays written by Professor Tissa Kumara over the years in the Sinhala language: 1) Aspects of Sri Lankan town planning emerging from Sinhala Sandesha poetry; 2) Health practices emerging from inscriptions of the latter part of the Anuradhapura period; 3) Buddhist religious background described in inscriptions of the Kandyan period; 4) Notions of aesthetic appreciation emerging from Sigiri poetry; 5) Rituals related to Sinhala clinical procedures; 6) Customs linked to marriage taboos in Sinhala society; 7) Food habits of ancient and medieval Lankans; and 8) The decline of modern Buddhist education. All these essays by Prof. Tissa Kumara and many others like them written by others remain untranslated into English or any other global language that holds intellectual power. The only exceptions would be the handful of scholars who also wrote in English or some of their works happened to be translated into English, an example of the latter being Prof. M.B. Ariyapala’s classic, Society in Medieval Ceylon.
The question I raised during my lecture was, what does one do with this knowledge and whether it is not possible to use this kind of knowledge profitably for theory building, conceptual and methodological fine-tuning and other such essential work mostly in the domain of abstract thinking that is crucially needed for social sciences and humanities. But this is not an interest these scholars ever entertained. Except for those who wrote fictionalised accounts such as unsubstantiated stories on mythological characters like Rawana, many of these scholars amassed detailed information along with their sources. This focus on sources is evident even in the titles of many of Prof. Tissa Kumara’s work referred to earlier. Rather than focusing on theorising or theory-based interpretations, these scholars’ aim was to collect and present socio-cultural material that is inaccessible to most others in society including people like myself. Either we know very little of such material or are completely unaware of their existence. But they are important sources of our collective history indicating what we are where we have come from and need to be seen as a specific genre of research.
In this sense, people like Prof. Tissa Kumara and his predecessors are human encyclopedias. But the knowledge they produced, when situated in the context of global knowledge production in general, remains mostly as ‘raw’ information albeit crucial. The pertinent question now is what do we do with this information? They can, of course, remain as it is. My argument however is this knowledge can be a serious source for theory-building and constructing philosophy based on a deeper understanding of the histories of our country and of the region and how people in these areas have dealt with the world over time.
Most scholars in our country and elsewhere in the region believe that the theoretical and conceptual apparatuses needed for our thinking – clearly manifest in social sciences and humanities – must necessarily be imported from the ‘west.’ It is this backward assumption, but specifically in reference to Indian experiences on social theory, that Prathama Banerjee and her colleagues observe in the following words: “theory appears as a ready-made body of philosophical thought, produced in the West …” As they further note, in this situation, “the more theory-inclined among us simply pick the latest theory off-the-shelf and ‘apply’ it to our context” disregarding its provincial European or North American origin, because of the false belief “that “‘theory’ is by definition universal.” What this means is that like in India, in countries like ours too, the “relationship to theory is dependent, derivative, and often deeply alienated.”
In a somewhat similar critique in his 2000 book, Provincialising Europe: Postcolonial Thought and Historical Difference Dipesh Chakrabarty points to the limitations of Western social sciences in explaining the historical experiences of political modernity in South Asia. He attempted to renew Western and particularly European thought “from and for the margins,” and bring in diverse histories from regions that were marginalised in global knowledge production into the mainstream discourse of knowledge. In effect, this means making histories of countries like ours relevant in knowledge production.
The erroneous and blind faith in the universality of theory is evident in our country too whether it is the unquestioned embrace of modernist theories and philosophies or their postmodern versions. The heroes in this situation generally remain old white men from Marx to Foucault and many in between. This indicates the kind of unhealthy dependence local discourses of theory owe to the ‘west’ without any attempt towards generating serious thinking on our own.
In his 2002 essay, ‘Dismal State of Social Sciences in Pakistan,’ Akbar Zaidi points out how Pakistani social scientists blindly apply imported “theoretical arguments and constructs to Pakistani conditions without questioning, debating or commenting on the theory itself.” Similarly, as I noted in my 2017 essay, ‘Reclaiming Social Sciences and Humanities: Notes from South Asia,’ Sri Lankan social sciences and humanities have “not seriously engaged in recent times with the dominant theoretical constructs that currently hold sway in the more academically dominant parts of the world.” Our scholars also have not offered any serious alternate constructions of their own to the world without going crudely nativistic or exclusivist.
This situation brings me back to the kind of knowledge that scholars like Prof. Tissa Kumara have produced. Philosophy, theory or concepts generally emerge from specific historical and temporal conditions. Therefore, they are difficult to universalise or generalise without serious consequences. This does not mean that some ideas would not have universal applicability with or without minor fine tuning. In general, however, such bodies of abstract knowledge should ideally be constructed with reference to the histories and contemporary socio-political circumstances
from where they emerge that may have applicability to other places with similar histories. This is what Banerjee and her colleagues proposed in their 2016 essay, ‘The Work of Theory: Thinking Across Traditions’. This is also what decolonial theorists such as Walter Mignolo, Enrique Dussel and Aníbal Quijano have referred to as ‘decolonizing Western epistemology’ and ‘building decolonial epistemologies.’
My sense is, scholars like Prof. Tissa Kumara have amassed at least some part of such knowledge that can be used for theory-building that has so far not been used for this purpose. Let me refer to two specific examples that have local relevance which will place my argument in context. Historian and political scientist Benedict Anderson argued in his influential 1983 book, Imagined Communities: Reflections on the Origin and Spread of Nationalism that notions of nationalism led to the creation of nations or, as he calls them, ‘imagined communities.’ For him, unlike many others, European nation states emerged in response to the rise of ‘nationalism’ in the overseas European settlements, especially in the Western Hemisphere. But it was still a form of thinking that had Europe at its center.
Comparatively, we can consider Stephen Kemper’s 1991 book, The Presence of the Past: Chronicles, Politics, and Culture in Sinhala Life where the American anthropologist explored the ways in which Sinhala ‘national’ identity evolved over time along with a continual historical consciousness because of the existence of texts such as Mahawamsa. In other words, the Sinhala past manifests with social practices that have continued from the ancient past among which are chronicle-keeping, maintaining sacred places, and venerating heroes.
In this context, his argument is that Sinhala nationalism predates the rise of nationalist movements in Europe by over a thousand years, thereby challenging the hegemonic arguments such as those of Anderson, Ernest Gellner, Elie Kedourie and others who link nationalism as a modern phenomenon impacted by Europe in some way or another. Kemper was able to come to his interpretation by closely reading Lankan texts such as Mahawamsa and other Pali chronicles and more critically, theorizing what is in these texts. Such interpretable material is what has been presented by Prof. Tissa Kumara and others, sans the sing.
Similarly, local texts in Sinhala such as kadaim poth’ and vitti poth, which are basically narratives of local boundaries and descriptions of specific events written in the Dambadeniya and Kandyan periods are replete with crucial information. This includes local village and district boundaries, the different ethno-cultural groups that lived in and came to settle in specific places in these kingdoms, migratory events, wars and so on. These texts as well as European diplomatic dispatches and political reports from these times, particularly during the Kandyan period, refer to the cosmopolitanism in the Kandyan kingdom particularly its court, the military, town planning and more importantly the religious tolerance which even surprised the European observers and latter-day colonial rulers. Again, much of this comes from local sources or much less focused upon European dispatches of the time.
Scholars like Prof. Tissa Kumara have collected this kind of information as well as material from much older times and sources. What would the conceptual categories, such as ethnicity, nationalism, cosmopolitanism be like if they are reinterpreted or cast anew through these histories, rather than merely following their European and North American intellectual and historical slants which is the case at present? Among the questions we can ask are, whether these local idiosyncrasies resulted from Buddhism or local cultural practices we may not know much about at present but may exist in inscriptions, in ola leaf manuscripts or in other materials collected and presented by scholars such as Prof. Tissa Kumara.
For me, familiarizing ourselves with this under- and unused archive and employing them for theory-building as well as for fine-tuning what already exists is the main intellectual role we can play in taking our cultural knowledge to the world in a way that might make sense beyond the linguistic and socio-political borders of our country. Whether our universities and scholars are ready to attempt this without falling into the trap of crude nativisms, be satisfied with what has already been collected, but is untheorized or if they would rather lackadaisically remain shackled to ‘western’ epistemologies in the sense articulated by decolonial theorists remains to be seen.

Extinction in isolation: Sri Lanka’s lizards at the climate crossroads
Climate change is no longer a distant or abstract threat to Sri Lanka’s biodiversity. It is already driving local extinctions — particularly among lizards trapped in geographically isolated habitats, where even small increases in temperature can mean the difference between survival and disappearance.
According to research by Buddhi Dayananda, Thilina Surasinghe and Suranjan Karunarathna, Sri Lanka’s narrowly distributed lizards are among the most vulnerable vertebrates in the country, with climate stress intensifying the impacts of habitat loss, fragmentation and naturally small population sizes.
Isolation Turns Warming into an Extinction Trap
Sri Lanka’s rugged topography and long geological isolation have produced extraordinary levels of reptile endemism. Many lizard species are confined to single mountains, forest patches or rock outcrops, existing nowhere else on Earth. While this isolation has driven evolution, it has also created conditions where climate change can rapidly trigger extinction.
“Lizards are especially sensitive to environmental temperature because their metabolism, activity patterns and reproduction depend directly on external conditions,” explains Suranjan Karunarathna, a leading herpetologist and co-author of the study. “When climatic thresholds are exceeded, geographically isolated species cannot shift their ranges. They are effectively trapped.”
The study highlights global projections indicating that nearly 40 percent of local lizard populations could disappear in coming decades, while up to one-fifth of all lizard species worldwide may face extinction by 2080 if current warming trends persist.

- Cnemaspis_kandambyi (Adult Male), Meemure, Matale District
Heat Stress, Energy Loss and Reproductive Failure
Rising temperatures force lizards to spend more time in shelters to avoid lethal heat, reducing their foraging time and energy intake. Over time, this leads to chronic energy deficits that undermine growth and reproduction.
“When lizards forage less, they have less energy for breeding,” Karunarathna says. “This doesn’t always cause immediate mortality, but it slowly erodes populations.”
Repeated exposure to sub-lethal warming has been shown to increase embryonic mortality, reduce hatchling size, slow post-hatch growth and compromise body condition. In species with temperature-dependent sex determination, warming can skew sex ratios, threatening long-term population viability.
“These impacts often remain invisible until populations suddenly collapse,” Karunarathna warns.
Tropical Species with No Thermal Buffer
The research highlights that tropical lizards such as those in Sri Lanka are particularly vulnerable because they already live close to their physiological thermal limits. Unlike temperate species, they experience little seasonal temperature variation and therefore possess limited behavioural or evolutionary flexibility to cope with rapid warming.
“Even modest temperature increases can have severe consequences in tropical systems,” Karunarathna explains. “There is very little room for error.”
Climate change also alters habitat structure. Canopy thinning, tree mortality and changes in vegetation density increase ground-level temperatures and reduce the availability of shaded refuges, further exposing lizards to heat stress.
Narrow Ranges, Small Populations
Many Sri Lankan lizards exist as small, isolated populations restricted to narrow altitudinal bands or specific microhabitats. Once these habitats are degraded — through land-use change, quarrying, infrastructure development or climate-driven vegetation loss — entire global populations can vanish.
“Species confined to isolated hills and rock outcrops are especially at risk,” Karunarathna says. “Surrounding human-modified landscapes prevent movement to cooler or more suitable areas.”
Even protected areas offer no guarantee of survival if species occupy only small pockets within reserves. Localised disturbances or microclimatic changes can still result in extinction.
Climate Change Amplifies Human Pressures
The study emphasises that climate change will intensify existing human-driven threats, including habitat fragmentation, land-use change and environmental degradation. Together, these pressures create extinction cascades that disproportionately affect narrowly distributed species.
“Climate change acts as a force multiplier,” Karunarathna explains. “It worsens the impacts of every other threat lizards already face.”
Without targeted conservation action, many species may disappear before they are formally assessed or fully understood.
Science Must Shape Conservation Policy
Researchers stress the urgent need for conservation strategies that recognise micro-endemism and climate vulnerability. They call for stronger environmental impact assessments, climate-informed land-use planning and long-term monitoring of isolated populations.
“We cannot rely on broad conservation measures alone,” Karunarathna says. “Species that exist in a single location require site-specific protection.”
The researchers also highlight the importance of continued taxonomic and ecological research, warning that extinction may outpace scientific discovery.
A Vanishing Evolutionary Legacy
Sri Lanka’s lizards are not merely small reptiles hidden from view; they represent millions of years of unique evolutionary history. Their loss would be irreversible.
“Once these species disappear, they are gone forever,” Karunarathna says. “Climate change is moving faster than our conservation response, and isolation means there are no second chances.”

Online work compatibility of education tablets
Enabling Education-to-Income Pathways through Dual-Use Devices
The deployment of tablets and Chromebook-based devices for emergency education following Cyclone Ditwah presents an opportunity that extends beyond short-term academic continuity. International experience demonstrates that the same category of devices—when properly governed and configured—can support safe, ethical, and productive online work, particularly for youth and displaced populations. This annex outlines the types of online jobs compatible with such devices, their technical limitations, and their strategic national value within Sri Lanka’s recovery and human capital development agenda.
Compatible Categories of Online Work
At the foundational level, entry-level digital jobs are widely accessible through Android tablets and Chromebook devices. These roles typically require basic digital literacy, language comprehension, and sustained attention rather than advanced computing power. Common examples include data tagging and data validation tasks, AI training activities such as text, image, or voice labelling, online surveys and structured research tasks, digital form filling, and basic transcription work. These activities are routinely hosted on Google task-based platforms, global AI crowdsourcing systems, and micro-task portals operated by international NGOs and UN agencies. Such models have been extensively utilised in countries including India, the Philippines, Kenya, and Nepal, particularly in post-disaster and low-income contexts.
At an intermediate level, freelance and gig-based work becomes viable, especially when Chromebook tablets such as the Lenovo Chromebook Duet or Acer Chromebook Tab are used with detachable keyboards. These devices are well suited for content writing and editing, Sinhala–Tamil–English translation work, social media management, Canva-based design assignments, and virtual assistant roles. Chromebooks excel in this domain because they provide full browser functionality, seamless integration with Google Docs and Sheets (including offline drafting and later (synchronization), reliable file upload capabilities, and stable video conferencing through platforms such as Google Meet or Zoom. Freelancers across Southeast Asia and Africa already rely heavily on Chromebook-class devices for such work, demonstrating their suitability in bandwidth- and power-constrained environments.
A third category involves remote employment and structured part-time work, which is also feasible on Chromebook tablets when paired with a keyboard and headset. These roles include online tutoring support, customer service through chat or email, research assistance, and entry-level digital bookkeeping. While such work requires a more consistent internet connection—often achievable through mobile hotspots—it does not demand high-end hardware. The combination of portability, long battery life, and browser-based platforms makes these devices adequate for such employment models.
Functional Capabilities and Limitations
It is important to clearly distinguish what these devices can and cannot reasonably support. Tablets and Chromebooks are highly effective for web-based jobs, Google Workspace-driven tasks, cloud platforms, online interviews conducted via Zoom or Google Meet, and the use of digital wallets and electronic payment systems. However, they are not designed for heavy video editing, advanced software development environments, or professional engineering and design tools such as AutoCAD. This limitation does not materially reduce their relevance, as global labour market data indicate that approximately 70–75 per cent of online work worldwide is browser-based and fully compatible with tablet-class devices.
Device Suitability for Dual Use
Among commonly deployed devices, the Chromebook Duet and Acer Chromebook Tab offer the strongest balance between learning and online work, making them the most effective all-round options. Android tablets such as the Samsung Galaxy Tab A8 or A9 and the Nokia T20 also perform reliably when supplemented with keyboards, with the latter offering particularly strong battery endurance. Budget-oriented devices such as the Xiaomi Redmi Pad remain suitable for learning and basic work tasks, though with some limitations in sustained productivity. Across all device types, battery efficiency remains a decisive advantage.
Power and Energy Considerations
In disaster-affected and power-scarce environments, tablets outperform conventional laptops. A battery life of 10–12 hours effectively supports a full day of online work or study. Offline drafting of documents with later synchronisation further reduces dependence on continuous connectivity. The use of solar chargers and power banks can extend operational capacity significantly, making these devices particularly suitable for temporary shelters and community learning hubs.
Payment and Income Feasibility in the Sri Lankan Context
From a financial inclusion perspective, these devices are fully compatible with commonly used payment systems. Platforms such as PayPal (within existing national constraints), Payoneer, Wise, LankaQR, local banking applications, and NGO stipend mechanisms are all accessible through Android and ChromeOS environments. Notably, many Sri Lankan freelancers already conduct income-generating activities entirely via mobile devices, confirming the practical feasibility of tablet-based earning.
Strategic National Value
The dual use of tablets for both education and income generation carries significant strategic value for Sri Lanka. It helps prevent long-term dependency by enabling families to rebuild livelihoods, creates structured earning pathways for youth, and transforms disaster relief interventions into resilience-building investments. This approach supports a human resource management–driven recovery model rather than a welfare-dependent one. It aligns directly with the outcomes sought by the Ministry of Education, the Ministry of Labour and HRM reform initiatives, and broader national productivity and competitiveness goals.
Policy Positioning under the Vivonta / PPA Framework
Within the Vivonta/Proprietary Planters Alliance national response framework, it is recommended that these devices be formally positioned as “Learning + Livelihood Tablets.” This designation reflects their dual public value and supports a structured governance approach. Devices should be configured with dual profiles—Student and Worker—supplemented by basic digital job readiness modules, clear ethical guidance on online work, and safeguards against exploitation, particularly for vulnerable populations.
Performance Indicators
From a monitoring perspective, the expected reach of such an intervention is high, encompassing students, youth, and displaced adults. The anticipated impact is very high, as it directly enables the transition from education to income generation. Confidence in the approach is high due to extensive global precedent, while the required effort remains moderate, centering primarily on training, coordination, and platform curation rather than capital-intensive investment.
We respectfully invite the Open University of Sri Lanka, Derana, Sirasa, Rupavahini, DP Education, and Janith Wickramasinghe, National Online Job Coach, to join hands under a single national banner—
“Lighting the Dreams of Sri Lanka’s Emerging Leaders.”
