Scientists predict changes in snakebite risks in Sri Lanka by 2050
By Ifham Nizam
A team of international scientists has conducted a groundbreaking study predicting significant changes in snakebite risks across Sri Lanka by the year 2050.
The research, led by Gerardo Martín, with contributions from Joseph James Erinjery, Dileepa Ediriweera, Eyal Goldstein, Ruchira Somaweera, H Janaka de Silva, David G Lalloo, Takuya Iwamura, and Kris A Murray, focuses on how climate change, land use, and population growth may impact snakebite incidents in the country.
Sri Lanka, known as a global hotspot for snakebites, faces the unique challenge of balancing human development with the preservation of its rich biodiversity. The study used advanced models to explore different future scenarios and to understand how these global changes might alter the landscape of snakebite risks.
According to the findings, while the overall incidence of snakebite envenoming could drop by up to 23% from 2010 to 2050, the reality is more complex.
The researchers identified that snakebite risks could decrease in the tropical lowlands but may increase in the highlands due to shifts in snake populations and habitats. This key finding reveals how environmental and social changes might alter human-snake interactions in various parts of the country, creating a diverse and uneven risk landscape. The study suggests that these changes could be driven by factors such as climate warming, deforestation, urbanisation, and agricultural expansion, which together affect both snake behavior and human exposure to snakes.
According to Renowned herpetologist Dr. Somaweera, their study dives into how global changes are shaping up snakebite risks in Sri Lanka, a global snakebite hotspot. “Using advanced models, we projected that from 2010 to 2050, the overall incidence of snakebite envenoming might drop by up to 23%—but it’s not all good news,” he said adding: “The effects vary widely depending on where you are in the country and which global change scenario plays out. For some areas, especially with higher population growth and land cover shifts, we’re seeing more complexity and even some potential increases in snakebite risk.”
The research team explored three contrasting development scenarios: one where the world follows a sustainability pathway with no further greenhouse gas emissions (SSP1), a middle-of-the-road pathway with moderate emissions reductions (SSP2), and a fossil-fuel-driven pathway with limited emissions reductions (SSP5). Interestingly, the study also suggests that in the least sustainable scenarios—where environmental protections are weakest—overall snakebite risks might decrease.
The team stressed that this comes with a cost: a potential decline in biodiversity, which could harm the environment in the long run. This scenario suggests that the impact of human activities could be so severe that even the snakes, which thrive in various environments, might struggle to survive, leading to a reduction in snakebite incidents.
The implications of these findings are significant. The study underscores the need for joint efforts between public health and conservation agencies to develop integrated strategies that balance human health with environmental and climate considerations.
The researchers recommend increasing epidemiological surveillance, enhancing prevention through educational campaigns tailored to specific socio-ecological contexts, and improving access to protective equipment and effective treatments. These strategies, they argue, are essential to mitigating the potential rise in snakebite incidents in certain areas while safeguarding both human populations and the natural environment.
Sri Lanka’s well-established data on venomous snake populations and snakebite envenoming incidence provided a solid foundation for this study. The research builds on this knowledge by incorporating three critical components of global change—climate, land use change, and population growth—into a single predictive framework. This approach not only adds a new layer of understanding to the dynamics of snakebite risk but also highlights the importance of preparing for the future by considering the complex interactions between these factors.
As the world continues to grapple with the effects of global change, the findings of this study serve as a reminder of the interconnectedness of human health and environmental sustainability.
The scientists hope that their work will inform future policies and actions in Sri Lanka and other snakebite-prone regions, helping to protect both people and nature in the face of an uncertain future.

Acid test emerges for US-EU ties
European Commission President Ursula von der Leyen addressing the World Economic Forum in Davos, Switzerland on Tuesday put forward the EU’s viewpoint on current questions in international politics with a clarity, coherence and eloquence that was noteworthy. Essentially, she aimed to leave no one in doubt that a ‘new form of European independence’ had emerged and that European solidarity was at a peak.
These comments emerge against the backdrop of speculation in some international quarters that the Post-World War Two global political and economic order is unraveling. For example, if there was a general tacit presumption that US- Western European ties in particular were more or less rock-solid, that proposition apparently could no longer be taken for granted.
For instance, while US President Donald Trump is on record that he would bring Greenland under US administrative control even by using force against any opposition, if necessary, the EU Commission President was forthright that the EU stood for Greenland’s continued sovereignty and independence.
In fact at the time of writing, small military contingents from France, Germany, Sweden, Norway and the Netherlands are reportedly already in Greenland’s capital of Nook for what are described as limited reconnaissance operations. Such moves acquire added importance in view of a further comment by von der Leyen to the effect that the EU would be acting ‘in full solidarity with Greenland and Denmark’; the latter being the current governing entity of Greenland.
It is also of note that the EU Commission President went on to say that the ‘EU has an unwavering commitment to UK’s independence.’ The immediate backdrop to this observation was a UK decision to hand over administrative control over the strategically important Indian Ocean island of Diego Garcia to Mauritius in the face of opposition by the Trump administration. That is, European unity in the face of present controversial moves by the US with regard to Greenland and other matters of contention is an unshakable ‘given’.
It is probably the fact that some prominent EU members, who also hold membership of NATO, are firmly behind the EU in its current stand-offs with the US that is prompting the view that the Post-World War Two order is beginning to unravel. This is, however, a matter for the future. It will be in the interests of the contending quarters concerned and probably the world to ensure that the present tensions do not degenerate into an armed confrontation which would have implications for world peace.
However, it is quite some time since the Post-World War Two order began to face challenges. Observers need to take their minds back to the Balkan crisis and the subsequent US invasions of Afghanistan and Iraq in the immediate Post-Cold War years, for example, to trace the basic historic contours of how the challenges emerged. In the above developments the seeds of global ‘disorder’ were sown.
Such ‘disorder’ was further aggravated by the Russian invasion of Ukraine four years ago. Now it may seem that the world is reaping the proverbial whirlwind. It is relevant to also note that the EU Commission President was on record as pledging to extend material and financial support to Ukraine in its travails.
Currently, the international law and order situation is such that sections of the world cannot be faulted for seeing the Post World War Two international order as relentlessly unraveling, as it were. It will be in the interests of all concerned for negotiated solutions to be found to these global tangles. In fact von der Leyen has committed the EU to finding diplomatic solutions to the issues at hand, including the US-inspired tariff-related squabbles.
Given the apparent helplessness of the UN system, a pre-World War Two situation seems to be unfolding, with those states wielding the most armed might trying to mould international power relations in their favour. In the lead-up to the Second World War, the Hitlerian regime in Germany invaded unopposed one Eastern European country after another as the League of Nations stood idly by. World War Two was the result of the Allied Powers finally jerking themselves out of their complacency and taking on Germany and its allies in a full-blown world war.
However, unlike in the late thirties of the last century, the seeming number one aggressor, which is the US this time around, is not going unchallenged. The EU which has within its fold the foremost of Western democracies has done well to indicate to the US that its power games in Europe are not going unmonitored and unchecked. If the US’ designs to take control of Greenland and Denmark, for instance, are not defeated the world could very well be having on its hands, sooner rather than later, a pre-World War Two type situation.
Ironically, it is the ‘World’s Mightiest Democracy’ which is today allowing itself to be seen as the prime aggressor in the present round of global tensions. In the current confrontations, democratic opinion the world over is obliged to back the EU, since it has emerged as the principal opponent of the US, which is allowing itself to be seen as a fascist power.
Hopefully sane counsel would prevail among the chief antagonists in the present standoff growing, once again, out of uncontainable territorial ambitions. The EU is obliged to lead from the front in resolving the current crisis by diplomatic means since a region-wide armed conflict, for instance, could lead to unbearable ill-consequences for the world.
It does not follow that the UN has no role to play currently. Given the existing power realities within the UN Security Council, the UN cannot be faulted for coming to be seen as helpless in the face of the present tensions. However, it will need to continue with and build on its worldwide development activities since the global South in particular needs them very badly.
The UN needs to strive in the latter directions more than ever before since multi-billionaires are now in the seats of power in the principle state of the global North, the US. As the charity Oxfam has pointed out, such financially all-powerful persons and allied institutions are multiplying virtually incalculably. It follows from these realities that the poor of the world would suffer continuous neglect. The UN would need to redouble its efforts to help these needy sections before widespread poverty leads to hemispheric discontent.

Shooting for the stars …
That’s precisely what 25-year-old Hansana Balasuriya has in mind – shooting for the stars – when she was selected to represent Sri Lanka on the international stage at Miss Intercontinental 2025, in Sahl Hasheesh, Egypt.
The grand finale is next Thursday, 29th January, and Hansana is all geared up to make her presence felt in a big way.
Her journey is a testament to her fearless spirit and multifaceted talents … yes, her life is a whirlwind of passion, purpose, and pageantry.
Raised in a family of water babies (Director of The Deep End and Glory Swim Shop), Hansana’s love affair with swimming began in childhood and then she branched out to master the “art of 8 limbs” as a Muay Thai fighter, nailed Karate and Kickboxing (3-time black belt holder), and even threw herself into athletics (literally!), especially throwing events, and netball, as well.
A proud Bishop’s College alumna, Hansana’s leadership skills also shone bright as Senior Choir Leader.
She earned a BA (Hons) in Business Administration from Esoft Metropolitan University, and then the world became her playground.
Before long, modelling and pageantry also came into her scene.
She says she took to part-time modelling, as a hobby, and that led to pageants, grabbing 2nd Runner-up titles at Miss Nature Queen and Miss World Sri Lanka 2025.
When she’s not ruling the stage, or pool, Hansana’s belting tunes with Soul Sounds, Sri Lanka’s largest female ensemble.
What’s more, her artistry extends to drawing, and she loves hitting the open road for long drives, she says.
This water warrior is also on a mission – as Founder of Wave of Safety,
Hansana happens to be the youngest Executive Committee Member of the Sri Lanka Aquatic Sports Union (SLASU) and, as founder of Wave of Safety, she’s spreading water safety awareness and saving lives.
Today is Hansana’s ninth day in Egypt and the itinerary for today, says National Director for Sri Lanka, Brian Kerkoven, is ‘Jeep Safari and Sunset at the Desert.’
And … the all-important day at Miss Intercontinental 2025 is next Thursday, 29th January.
Well, good luck to Hansana.
