History tells us pandemics have devastatingly interrupted civilizations. They killed millions of humans and brought forth misery and poverty, but never wiped out a civilisation. Epidemics and pandemics begin, escalate and wane or re-emerge. However, the causative agent rarely disappears; it opts for a less vicious coexistence. Smallpox is the only epidemically potent disease that has been eliminated absolutely – not via natural processes but by the intervention of human intelligence.

Life has been created by natural forces endowing an essence for it to reproduce and undergo change. We ourselves and the virus exist because of this, which also enables the virus to adapt itself to the environment, survive and expand causing the pandemic. In ancient times, humans had to await the consequences of the same natural forces to face a pandemic – those who remained fit and immune survived and reproduced.

Today, human intelligent intervention makes things more favourable to us than to the virus, and helps many who lack the natural immunity survive. The eventuality of the present pandemic will be determined by the effort we make to combat it.

 

How pandemics originate

Persian philosopher Ibn Sina was probably the first to conjecture that living entities in the human body caused diseases. Later, Louis Pasteur proved infections occurred when microscopic organisms entered the body and proliferated and those microbes could pass from one individual to another.

Microbes do not emerge spontaneously; nor do they arrive from the sky. They exist everywhere in the environment as creations of biological evolution. Humans, animals and plants harbour them. Microbes associated with a given species, often symbiotic, pose no danger to the host, whose immunity prevents their undue proliferation. They are selective; those present in one species would not easily move to a different type of host and get established. Nevertheless, the complexity of living things allow exceptions. Occasionally a pathogen or innocuous microbes concealed in animals or found in the environment can jump to a human causing diseases.

An illness acquired from an animal is referred to as a zoonotic disease or a zoonosis. Sometimes, the zoonosis turns out be contagious. Almost all calamitous epidemics and pandemics have arisen from accidental transfer of a bacteria or a virus from an animal species to humans and subsequent evolution- their origin is zoonotic. Ebola, Severe Acute Respiratory Syndrome, Middle East Respiratory Syndrome and COVID-19 are zoonotic diseases. The zoonotic infections such as plague, smallpox, measles and swine flu caused first magnitude pandemics in the past.

 

Ebola Virus Disease: near pandemic situation 2014-2016

A previously unknown sickness broke out near the Ebola River in Congo in 1976, killing almost 80% of persons who contracted it. The cause of the disease, subsequently named Ebola, was found to be a virus endemically associated with bats. Although the virus does no harm to the bats, when transferred to humans via contact during hunting, a fatal condition, similar to a flu occurs. The exposure to body fluids of the infected persons passes the disease to the community. The Ebola outbreak 2014-2016, spread across West Africa. Some cases were also reported in Europe and the United States.

 

Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS): The older cousins of COVID-19

Coronaviruses with crown like spikes on the surface exist everywhere. Until early 2000s, they were not considered a threat to humans. In 2002, a new contagious respiratory disease, SARS, emerged in China and spread rapidly to several other countries. International corporation; coordinated by WHO quickly elucidated the nature of the condition. The cause of the disease was identified to be a virus harboured by some bats, transferred to humans by palm civets. Handling civet cat meat in wet markets is believed to have caused the transmission of the pathogen to humans. The epidemic was effectively controlled by isolation of infected persons, use of masks, protective equipment, physical distancing and thermal sensing of passengers in airports. In July 2003, WHO declared SARS had been contained.

Another respiratory viral disease MERS first reported in Saudi Arabia in 2012 crossed continents due to air travel. The second major MERS outbreak occurred in South Korea in 2015. Compared to SARS, MERS is more virulent but less contagious, and spreads through close contacts of infected persons. The origin of MERS virus is zoonotic, bats being the primary source and camels the intermediate which transferred the pathogen to humans. The virus may have undergone genetic change in camels facilitating its adaptation to humans.

 

How pandemics evolve

Pandemics and epidemics begin when an infectious agent enters a community possessing no immunity to resist. A tragic example is measles epidemic in Fiji. In 1875, an Australian delegation carried the virus to the island whose natives were never exposed to the measles – a disease quite common in Asia and Europe. In a matter of months 30 percent of the population died!

Zoonotic viruses are particularly dangerous because humans are not exposed to them at the beginning. The absence of immunity allowed an epidemic in one locality to expand as a pandemic. Furthermore, when a virus originally found in an animal, genetically and associatively distant from humans, is harboured in an intermediate host closer to humans, some genetic intermingling could occur via processes referred to as recombination and re-assortment. This way, the virus acquires a foreignness needed to evade the human immune response and a kinship favourable for adaptation. Domesticated animals sometimes carry viruses originally derived from humans but genetically modified. A virus found in a wild animal co-infecting a domesticated one can copy genetic information from the latter producing a new kind of virus, adaptable to humans and also withstand host immunity.

The origin of the virus causing COVID-19 named SARS-Cov-2 has been traced to a bat species. The genetic make-up of SARS-Cov-2 tally nearly 95 percent with a virus found in so-called horseshoe bats. It is not conclusive whether the virus passed directly from a bat to humans or through an intermediate host. There exists no evidence to support the conspiracy theories that the virus leaked from a laboratory. Finding out how the virus came into being would shed light on how to control it effectively.

Once a pathogen enters a population devoid of immunity, the number of infected people begins to expand exponentially at a rate proportional to the population density reaching a peak. Thereafter, because of the decrease of susceptible persons owing to acquisition of immunity and deaths, the disease wanes.

Mathematical models predict above behaviour and point to the important concept of the effective reproduction number of a progressing epidemic. Effective reproduction number (RE) is the average number of people who acquire the infection from one infected individual at a given time. The idea of reproduction number was first introduced by the British Physician Ronald Ross, who took up mathematics to find a way to eradicate malaria. Ross showed that in order to control an epidemic RE needed to be kept below one. His suggestions for doing this paved the way for the eradication of malaria epidemics in Sri Lanka. In the initial phases of the COVID-19 pandemic in Wuhan, China RE has been in the range 3-5. Control measures such as physical distancing, wearing masks and isolation reduce RE, but the issue is reducing the number further to reach values below one. The mode of evolution of the COVID-19 pandemic is complicated by human migration by imposition and withdrawal of preventive measures.

Transmissibility and virulence

The virus is not after vengeance to be noxiously virulent and kill as many as possible; evolution in that direction renders no advantage because if a large majority of infected persons die, the virus will be deprived of hosts to feed on and reproduce.

The probability that someone will catch the infection from an infected person depends on the rate and quantity of the pathogen transmitted. A severe infection produces larger progeny of viruses; this has some advantage to the virus. Generally, pathogens compromise between transmissibility and virulence giving a higher weightage to the former. The transmissibility of COVID-19 is high because the infected shred the virus before symptoms fully develop. Contrastingly, in case of SARS; the infected release the pathogen at later stages when symptoms are readily identifiable enabling isolation; this is the main reason why SARS was contained and the COVID-19 transmission continues.

The virus aggressively attacking elderly and sparing younger could also be an advantage to the virus. Severely sick elderly patients release larger quantities of virus, infecting the younger who take care of them. The younger move about and infect others. The virus wants to procreate and exploits everything possible for that purpose!

Variations of the virus

Zoonotic viruses undergo major genetic changes via recombination or re-assortment and adapt to human system. Mutations enable them to fine-tune the traits favourable for adaptation by small genetic adjustments. When viruses replicate, their genetic code is sometimes copied erroneously, resulting in random variations. The process is analogous to typographical errors you make when you retype your essay. Even if you retype thousand times, you would not expect to find an improved version of the essay as result of random typographical errors. However, when a virus replicate trillions of times; a more adaptable one may originate and replicate endlessly – these are new strains of the virus. Recently, more contagious strains have been found to proliferate in the UK, Brazil and South Africa. The British Prime Minister announced that the variant identified in his country seemed to be more virulent.

Convergent evolution of strains

The three strains of the virus (United Kingdom, Brazil and South Africa) seemed to have evolved independently. Yet, all the three variants have undergone similar changes in the spike protein, enabling the virus to attach to host cells more strongly; this is essential for efficient spreading. The qualities acquired indicate that mutations have got selected for the definite purpose of convergence to the same cause – to spread the disease fast.

Convergent evolution is quite common in nature. A prototypical example is the near identical streamlined body shapes of the shark and the dolphin. Shark is classified as a primitive fish, whereas the dolphin has been an evolutionarily modern four-legged mammal that lived on land adapted to the ocean. Both shark and dolphin independently evolved towards the optimum hydrodynamic body features to be able to swim fast.

Future of the Present Pandemic and Future Pandemics

It is too early to determine the degree of effectiveness of existing vaccines to new and emerging strains. Fortunately, some vaccines can be easily reprogrammed to provide immunity to new strains. The world will soon acquire the arsenal of weapons needed to fight it. Efficacious vaccines have been demonstrated, and many are in the pipeline. Antiviral drug research progresses although to date there exist no cure for COVID-19. The virtues of physical distancing, wearing masks, contact tracing and isolation are gaining acceptance. Hopefully wide vaccinations programmes and strict adherence to preventive measures will help subdue the pandemic; a concerted effort is imperative. As pointed out in the editorial The Island editorial of 21st January 2021 ensuring equitable access to vaccines is an urgency. This the factor determining what lies ahead and how the pandemic will halt.

Doing the needful forthwith is prudent because given sufficient time the virus might mutate in response to a single political decision implemented somewhere, irrespective of the geographical location.

The other issue would be the emergence of new pandemics in the future – most likely those of zoonotic origin. During the past two decades many such diseases have surfaced. Excessive interference with environment; clearing forests, maintaining millions of farm animals in unnatural conditions and climate change resulting from burning fossil fuels probably contribute this dangerous trend.

When humankind turns cruel to animals, destroy flora and engender environment, the return could be a pandemic!

Making ‘Sinhala Studies’ globally relevant

Published

on

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

Published

on

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.

Cnemaspis rajakarunai (Adult Male), Salgala, Kegalle District (In a communal egg laying site)

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.

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

Published

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.”
