What is DNA and What Does it Do? A Deep Dive into the Blueprint of Life

In the intricate web of life, DNA stands as the cornerstone of biological existence, shaping everything from the simplest bacteria to the complexity of human beings. While the term “DNA” is often tossed around in discussions about genetics, crime scene investigations, and ancestry, the profound significance of this molecule remains underappreciated by many. To truly understand life at a molecular level, one must delve into the essence of DNA—what it is, how it functions, and why it is crucial to life on Earth.

DNA, or deoxyribonucleic acid, is a molecule that carries the genetic instructions used in the growth, development, functioning, and reproduction of all living organisms and many viruses. In simpler terms, it’s the blueprint that dictates how a living organism is built and how it operates. Structurally, DNA is a long molecule (polymer) made up of repeating units called nucleotides. Each nucleotide consists of three components: a sugar molecule (deoxyribose), a phosphate group, and one of four nitrogenous bases—adenine (A), thymine (T), cytosine (C), or guanine (G). Within the DNA molecule, the bases pair with each other specifically (A with T, and C with G), forming the famous double helix structure, discovered by James Watson and Francis Crick in 1953.

The primary function of DNA is to store and transmit genetic information. The order of the nucleotides within the DNA molecule forms the genetic code, which is unique to an individual. This code is comparable to sentences of a language, and spell out instructions for building and maintaining that particular organism. A gene, which represents a unit of instruction, contains the information for making a particular protein or set of proteins. Proteins, in turn, perform a vast array of functions within living organisms, from building cellular structures to regulating biochemical reactions. The long DNA strands within an organism are organized into structures called chromosomes. Humans, for instance, have 23 pairs of chromosomes, totaling 46. Each chromosome is a single, continuous strand of DNA, and the set of 46 chromosomes contain the entire genetic blueprint for a human being—about 3 billion (109) “letters” long.

One of the most remarkable features of DNA is its ability to replicate itself. This is crucial for life because it allows genetic information to be passed from one generation to the next during reproduction. The process of DNA replication begins with unwinding of the double helix, thus separating into two strands. Each strand then serves as a template for the formation of a new complementary strand. As a result, two identical double-stranded, helical DNA molecules are formed, each containing one original strand and one newly synthesized strand. This semi-conserved method of replication ensures that genetic information is accurately copied, preserving the integrity of the genetic code across generations.

While DNA stores the instructions for life, proteins are the elements of function. The process of converting the information contained in DNA to that of a protein is known as transcription and translation. The information encoded within a gene is first “transcribed” into a message. This message, written in the language of DNA, must then be “translated” into a series of amino-acids, the building blocks of proteins. This process of building proteins based on the genetic code occurs within each and every living cell, and is aided by specialized structures known as ribosomes. This flow of genetic information from DNA to protein is known as the “central dogma” of molecular biology. It underscores the critical role of DNA in guiding the development and functioning of all living organisms.

DNA is also the hereditary material in humans and almost all other organisms. When organisms reproduce, they pass on copies of their DNA to their offspring. This transfer of genetic information ensures that offspring inherit traits from their parents, such as eye color, hair texture, and susceptibility to certain diseases. The study of how traits are inherited is known as genetics, and it has revolutionized our understanding of biology. For instance, Gregor Mendel’s pioneering work in the 19th century laid the foundation for modern genetics by demonstrating that traits are inherited in discrete units, now known as genes. Today, we know that these genes are made of DNA, and we can even manipulate DNA to understand and influence the inheritance of traits.

Mutations are changes in the DNA sequence that can occur naturally during DNA replication or due to environmental factors like radiation or chemicals. While many mutations are harmless or even beneficial, some can lead to diseases, such as cancer. Mutations are a primary source of genetic variation and diversity, which is essential for evolution. Over time, mutations can accumulate and lead to new traits that may provide an advantage in a particular environment. These advantageous traits are more likely to be passed on to future generations, driving the process of natural selection and the evolution of species.

The discovery of the structure and function of DNA has paved the way for numerous biotechnological advancements. One of the most significant is genetic engineering, where scientists can alter the DNA of organisms to produce desired traits. For example, genetically modified organisms (GMOs) have been created to improve crop yields, enhance nutritional content, and confer resistance to pests and diseases. Another groundbreaking development is CRISPR technology, a powerful new tool for precise DNA editing. CRISPR allows scientists to make targeted changes to the DNA of living organisms, offering potential treatments for genetic disorders, the creation of disease-resistant plants, and even the possibility of eradicating certain genetic diseases.

Moreover, technologies which enable the decoding of DNA and deciphering the underlying code have revolutionized fields like medicine, forensics, and anthropology. The ability to decode the entire human genome has provided unprecedented insights into genetic diseases, human evolution, and our relationship to other primates.

One of the most well-known applications of DNA technology is in forensic science. DNA profiling, also known as DNA fingerprinting, is a technique used to identify individuals based on their unique genetic makeup. Because every individual (except identical twins) has a unique DNA sequence, DNA evidence can be used to match biological samples from a crime scene to a suspect, providing crucial evidence in criminal investigations. DNA profiling has been instrumental in solving countless cases, from high-profile criminal investigations to identifying victims of disasters. This technique can also be used in paternity testing, ancestry tracing, as well as for the identification of remains.

While the ability to manipulate and analyze DNA has brought about tremendous benefits, it also raises important ethical questions. For instance, the use of genetic information in medicine and insurance raises concerns about privacy and discrimination. There is also debate about the morality of genetic modifications, particularly in humans, where the potential for “designer babies” has sparked controversy. Furthermore, the possibility of cloning, which involves creating a genetically identical copy of an organism, raises questions about identity, individuality, and the implications of creating life artificially. The ethical implications of these technologies are complex and multifaceted, requiring careful consideration as we continue to push the boundaries of what is possible with the manipulation of DNA.

As we continue to explore the vast potential of DNA, we must also navigate the ethical, legal, and social implications of this knowledge. The power to manipulate the very blueprint of life comes with great responsibility, and society must grapple with the consequences of our growing ability to edit, decode, and understand DNA. DNA is the molecular foundation of life, carrying the instructions that define the form and function of every living organism. From its role in heredity to its central place in the processes of life, DNA is a testament to the complexity and beauty of biology. As we continue to unlock the secrets of this remarkable molecule, we are poised to make discoveries that will not only deepen our understanding of life but also transform medicine, agriculture, and countless other fields. However, with these advancements come ethical considerations that must be carefully weighed to ensure that the benefits of DNA technology are realized responsibly and equitably.

Science and diplomacy in a changing world

Published

on

Two editors: Dr. Palitha Kohona (L) and Prof. Ranjith Senaratne

Today marks a truly historic and momentous occasion in the realm of transdisciplinary diplomacy in our country. We gather here with a twofold purpose of profound national and global significance: the establishment of the Science Diplomacy Forum, and the launch of the volume Science Diplomacy: National, Regional and Global Approaches in a Changing World.

This volume brings together valuable and timely contributions from internationally renowned experts representing all key regions of the world — North America, Latin America, Europe, Africa, West Asia, South Asia, and Oceania. It reflects a rich diversity of perspectives, experiences, and insights that speak to the increasingly interconnected nature of science, policy, and diplomacy in our rapidly transforming world.

I am deeply heartened — and indeed humbled — by the presence of such a distinguished constellation of leaders, professionals, intellectuals, scholars, and luminaries from diverse domains, including international relations, science and technology, higher education, and governance. It is rare to witness such an extraordinary and diverse assembly of intellectual, professional, and academic excellence under one roof. Your presence affirms the importance of the cause we serve and the promise of the path we are charting together. Your support, encouragement, and engagement give life, purpose, and direction to this vital endeavour.

As Chief Editor of this volume, it is both a great honour and a profound responsibility to extend a warm and heartfelt welcome to all our distinguished guests and invitees. I am conscious that this august gathering is not assembled to listen to a lengthy welcome address, but rather to engage with the substantive proceedings of this event, enriched by five eminent personalities, four distinguished speakers, and an able and competent moderator — all of whom possess exceptional mastery of the subject. I shall therefore be brief.

Among us today are former and current Ministers and people’s representatives, members of the diplomatic corps, Secretaries to Ministries, distinguished panelists, valued contributors to the volume, Vice-Chancellors, Members of the Board of Management and Academic Affairs Board of the BCIS, Heads of institutions, professors, senior government officials, professionals, journalists, and many others — too numerous to acknowledge individually, yet each of you is most warmly welcomed. I receive you all, whether present in person or online, with the utmost warmth, respect, and appreciation.

The panel discussion constitutes the pièce de résistance of this event. We are deeply honoured to be joined by four eminent personalities:

Her Excellency Siri Walt, Ambassador of Switzerland to Sri Lanka;

Professor Pierre-Bruno Ruffini, former Chair of the EU Science Diplomacy Alliance; and former Ambassadors Mr. Bernard Goonatilleke and Dr. Palitha Kohona — all of whom bring exceptional depth of experience and insight to this important subject.

Their discussion will be guided by our distinguished moderator, Mr. Naushard Cader, a truly cosmopolitan personality, widely respected for his breadth of knowledge and his keen understanding of global affairs and science diplomacy. I extend to all our speakers and our moderator a very warm welcome and my sincere appreciation for their willingness to share their wisdom with us this evening.

Allow me, however, to place this event in perspective.

We gather this evening not merely to introduce a book, nor solely to inaugurate a forum, but to reflect together on an idea whose time has unquestionably arrived.

We meet at a moment of profound global transition and conflict. The international landscape is marked by turbulence, uncertainty, and rapid transformation. The world is shifting from a relatively stable post–Cold War configuration toward an increasingly multipolar order. While multipolarity carries the promise of greater balance and strategic autonomy, it also brings intensified competition among major powers, fluid alliances, and growing unpredictability.

At the same time, the rules-based international order — which for decades provided smaller nations with a measure of predictability and protection — is under visible strain and threat. Institutions are contested. Norms are challenged. Economic interdependence deepens even as geopolitical fragmentation intensifies. Supply and value chains now account for nearly seventy percent of global trade, binding nations in complex webs of mutual dependence. Yet such interdependence has not prevented trade wars, sanctions regimes, technological decoupling, and regional conflicts.

For small and economically vulnerable states, this evolving environment is especially daunting. When global rules weaken, asymmetries of power become more pronounced. Bilateral negotiations between unequal partners can leave smaller nations disadvantaged. Without adequate legal, geological, scientific, technological, and diplomatic expertise, such states may struggle to safeguard their long-term national interests and sovereignty. Vulnerability, in the absence of knowledge and capacity, risks translating into marginalisation.

Overlaying this geopolitical transformation is a constellation of interconnected global challenges. Climate change is no longer a distant projection; it is a lived reality. Sea levels are rising. Extreme weather events are intensifying. Food, water, and energy security remain fragile. Pandemics have exposed vulnerabilities in global health systems. Cyber threats transcend borders. Environmental degradation, biodiversity loss, and marine pollution threaten livelihoods and ecosystems alike.

These challenges are systemic and transboundary. Almost every major issue — whether global, regional, or national in scale — involves science and technology, either in understanding root causes or in devising effective solutions.

Traditional diplomacy, while indispensable, is no longer sufficient on its own. The defining issues of our time are not purely political or military; they are scientific, technological, environmental, and societal. They demand evidence-based policymaking, interdisciplinary collaboration, and sustained transnational cooperation.

It is within this context that science diplomacy emerges — not as an academic abstraction, but as a strategic necessity.

Nowhere are these realities more visible than in the Indian Ocean.

Unlike the Atlantic or Pacific Oceans, which possess longstanding institutional architectures and extensive scientific mapping, the Indian Ocean remains comparatively underexplored and under-institutionalised. Covering roughly one-fifth of the world’s oceanic expanse, it carries a substantial share of global energy shipments and maritime trade. Its seabed resources — including critical and rare-earth minerals — remain only partially surveyed. Many of its coastal and island nations are developing economies with limited scientific and technological capacity to explore, monitor, and sustainably manage these resources.

The Indian Ocean is unique. It is bordered predominantly by developing and emerging states. It hosts remarkable cultural, religious, and political diversity. It is home to some of the world’s most climate-vulnerable communities. Increasingly, it has become a central theatre of global strategic competition, viewed by some nations through distinct geostrategic lenses.

This maritime space is simultaneously a lifeline and a fault line. It sustains global commerce and local livelihoods. Yet it is also a theatre where geopolitical interests intersect — sometimes converge, sometimes collide.

At the heart of this ocean lies Sri Lanka.

Geographically, our island sits astride one of the busiest East–West shipping routes in the world. Historically, Sri Lanka has been a hub of commercial, cultural, and intellectual exchange. Today, that strategic location presents both opportunity and responsibility.

Sri Lanka’s history, enriched by iconic figures such as Dr. Gamini Corea, Hon.

Lakshman Kadirgamar, Judge Christopher Weeramantry, Dr. Neville Kanakaratne and Dr. Jayantha Dhanapala, stands as a powerful testament to our long-standing contributions to global diplomacy and international governance. Our nation provided leadership within the Non-Aligned Movement, positioning itself as a bridge between civilizations at a time of deep ideological division. We also made history by producing the world’s first woman Prime Minister, affirming our commitment to political progress and inclusive governance.

Today, we are called upon once again to build upon this distinguished legacy — by championing regional unity, promoting sustainable development, and addressing critical contemporary challenges such as climate change, maritime security, and environmental sustainability.

We must navigate complex geopolitical currents while safeguarding sovereignty and strengthening economic resilience. We face vulnerabilities common to island and littoral states: climate change, coastal erosion, marine pollution, and supply chain disruptions. Our development aspirations must be balanced with environmental stewardship and maritime security considerations.

Yet within these challenges lies profound opportunity.

Sri Lanka can position itself as a regional convener — a hub for ocean science, climate research, marine biodiversity studies, disaster risk reduction, and blue economy innovation. Through platforms such as BIMSTEC, the Indian Ocean Rim Association, and SAARC, we can advance cooperative marine research, harmonise environmental standards, strengthen early warning systems, and promote sustainable maritime governance grounded in international law.

But to do so effectively, we must invest in knowledge — and in the diplomacy of knowledge.

Science diplomacy operates along three mutually reinforcing dimensions:

First, science in diplomacy — where scientific evidence informs foreign policy decisions.

Second, diplomacy for science — where diplomatic engagement enables international research collaboration and shared infrastructure.

Third, science for diplomacy — where scientific cooperation itself becomes a bridge for confidence-building, even when political relations are strained.

Importantly, science diplomacy extends beyond the natural sciences. The humanities and social sciences are equally vital. Technology must be guided by ethics. Data must be interpreted within cultural contexts. Policy must consider equity and justice. Diplomats of the future must be fluent not only in international law and negotiation, but also in scientific literacy and interdisciplinary thinking.

In a fragmented world, science offers a neutral vocabulary. It encourages transparency, peer review, and open data. It shifts discourse from rhetoric to evidence. It fosters long-term thinking in political environments often dominated by short-term calculations.

For small and vulnerable nations, science diplomacy is empowerment. It strengthens capacity. It enhances credibility. It enables engagement with larger powers on firmer ground — armed not merely with moral argument, but with data, research, and technical expertise.

The book we launch today reflects a diversity of experience and insight. It is intentionally transdisciplinary because the problems we face are transdisciplinary. It is intentionally global because no region can address these challenges in isolation.

In Sri Lanka, science diplomacy remains at a formative stage. The establishment of the Science Diplomacy Forum signals our determination to move beyond dialogue toward sustained institutional engagement. It envisions training programmes for diplomats and scientists, embedding scientific advisory mechanisms within governance structures, and building networks among universities, research institutes, industry, and policymakers. It seeks to cultivate a new generation equipped to navigate the interface between knowledge and negotiation.

We aspire for the Science Diplomacy Forum to be transformative — a true game changer.

Excellences, Ladies and Gentlemen,

We live in an era of mounting uncertainty — but also of extraordinary human ingenuity. The same interconnectedness that transmits crises also enables collaboration. The same technologies that disrupt can also heal and transform.

Change is inevitable. The deeper question is whether we will shape that change cooperatively, constructively, and inclusively.

For Sri Lanka, for the Indian Ocean region, and for the broader global community, science diplomacy offers a pathway beyond zero-sum thinking. It channels competition into collaboration around shared public goods. It aligns national interest with regional stability. It transforms vulnerability into resilience through knowledge.

Let this book be not merely a publication, but a platform for sustained reflection and action.

Let the Science Diplomacy Forum be not merely an institution, but a living bridge between evidence and policy, between research and responsibility, between nations and neighbours.

Let Sri Lanka reaffirm its role as a bridge — not a battleground — in the Indian Ocean.

In a world where rules may falter, let evidence guide us.

In a world where tensions may rise, let dialogue endure.

In a world of turbulence, let science diplomacy be our compass — guiding us toward peace, stability, dignity, and shared prosperity.

From one day of celebration to 364 days of transformation

The international women’s day was just celebrated all over the world. I saw many organiations share their slogans, and organize panel discussions, presentations, and exhibitions to support women empowerment. Slogans, themes, colors play vivid and vociferous role across the world, commemorating the international women’s day.

Alas, the colors are faded, slogans are weaned, themes are forgotten, over the next 364 days, pushing UN Chapter on Women’s Rights come up with more illustrious themes and slogans.

From Bread and Peace to Rights and Action

According to the recorded history, the Women’s day first introduced on 28th February 1909 in America, raising a voice of women against poor working conditions and poor pay in garment factories. This took a more revolutionary form in 1917 in Russia against World War I, where a mass of women protested under the theme of “Bread and Peace”.

Starting from basic needs such as bread and peace, the International Women’s Day theme has evolved towards freedom and independence, justice and inclusion.

Over the years, the rise of feminism brought cultural refinements and highlighted women’s rights. Looking back the historical evolution of women’s role, we see that matrimony has faded and patriarchy evolved with religious and geopolitical forces intertwined with the social expectation. The importance and respect for women, given in the ancient civilisations, diminished with medieval civilization, and subsequent colonisation. The rise of patriarchy domesticated women as homemakers, at the same time prompting their voices to rise for dignity and equitable treatment.

Rise of Feminism

In a typical Western-household of 20th century, husband was the bread winner of the family and the wife managed household affairs. In this era, women’s affairs were restricted to daily chores, creating a boundary wall restricting their access to corporate jobs, free voices. Betty Friedman was a remarkable lady who observed the domestic suffering of women and challenged ‘feminine mystique’ through her 1963 book. She disclosed the feminine mystique, which celebrated women as good housewives, and the belief that women could find satisfaction from domestic chores, home making, marriage, raising children, cooking, washing and taking care of husband’s needs. Betty disclosed that the unhappiness and boredom experienced by the domesticized women, and their inability to live up to the feminist mystique defined by the male dominant society had no name and difficult to express in words. Betty’s claim was supported by the theories of Abraham Maslow, who introduced motivation to grow along the hierarchy of needs. Betty, declared that feminine mystique denies basic growth needs of women, where their desires limited to shelter, food, safety and love only.

In this era women’s jobs were confined preeminently to teaching, and caregiving. STEM fields: science, technology, engineering and medicine were dominated by males, leaving less space for women. As you may have heard in the medieval era women who practiced medicine were branded as ‘witches’ and many were burned alive rooting out the knowledge and courage of women. Women who practiced and taught science and astronomy, were also branded for witch craft and condemned to death. The social pressure suppressed women confining them to domestic chores. In the industrial era women were hired for factory work under low wages and less facilities. In this period Women’s organisations were gathered demanding freedom and justice for women, calling for equal opportunities and rights enjoy their male counterparts. The evolution of women’s movements culminated in 1975, where the first International Women’s Day was commemorated on 8th March 1975.

Celebration and Contradiction

Since 1975, women were celebrated for a day in every year across the globe, with various themes and color codes to showcase the world that all women have rights and demanding fair treatment. The theme colors of International Women’s day are Purple, Green and White.

Purple stands for justice, dignity, and loyalty to the cause.

Green for hope and growth.

White for purity and unity.

In 1996, the International Women’s Day declared a theme to embrace, which is; “Celebrating the Past, Planning for the Future.” In the year 2023, the theme was ‘Embrace Equity’, which evolved to ‘Inspire inclusion’ in 2024, and the year 2025 theme was ‘Accelerate Action’. In 2026, there are three themes; 1. Give to Gain, 2. Balance the Scales, 3. Rights. Justice. Action.

Fragmented Focus Diminishes Values

Multiple themes and competing messages can unintentionally dilute momentum. Unity is not uniformity, but coherence matters; shared direction makes shared progress possible. Emerging three themes to celebrate international women’s day in 2026, implicate lack of solidarity, and unity among women’s organizations to share a common theme. Inclusion, equity and accelerated action have not yet achieved by the women globally, neither locally, nor in small communities. We are bound to question whether the women stay true to the meanings of theme colors that represent womanhood.

Thus, isn’t it vital to explore what goes wrong with our themes and slogans on this Women’s day, before setting foot without solid foundation for what we claim for? Or is it only a day that dawn women’s organisations to gather women in elite society, or identified group of women to enjoy a cup of tea over futuristic speeches of identical society, which treat women with high respect and equity?

One thing we must understand is the world is evolving, so does the roles, rights, and actions of women. Although, women shouted and pleaded for opportunities to enter male dominate world of work, today in many countries including Sri Lanka, women occupies majority of administrative positions and clerical level jobs. Even, the labour positions, dominated by males, are now occupied by the females in many sectors. However, women still bear the traditional homemaker role as well, while juggling with work, and studies to sustain jobs and promotions. This modern day scenario has made women more prone to chronic stress related deceases. The break of rest, too rigid demands coming from work and family, their own desires to move up the corporate ladder, outsmart neighbourers, and craving to make their children better than the others have made women’s lives miserable and breaching the themes and slogans that cater to the women’s prosperity.

Today’s environment has resulted many women to abandon dignity, purity, and hope, overlook unity and justice. If you see social media contents shared by women, you may not be surprised by my statements. The dignity, purity and hope for betterment of women is vanishing on screen. Young girls’ addiction to drugs, liquor and tobacco, sexual misbehaviour, and rising school-aged pregnancies are critical concerns that women’s movements must pay attention today.

What We Must Demand Now: Right Education and Just Acts

Women’s day slogans need a shift. Rather than demanding equal rights as men, we must demand right education for women and girls. We shall not stop at demanding justice as given to the men, but shout and make women and girls aware of ‘Just Acts’, and encourage them to act justly, for themselves, without exposing them to be victims of social media, and ill temptations.

Digital lives of women and girls can amplify comparison, quick outrage, and performative ideals. For girls and women, this can mean unrealistic bodies, curated success, and unsafe online spaces. What we need isn’t more judgment; it’s digital literacy, psychological safety, reproductive health awareness, and robust support systems, so women can flourish on and off‑line. We must educate women and nourish and foster the moral values among women and girls to stay pure in thoughts and actions, we must empower women and girls to keep hope and grow continuously. We must share a culture of inclusion among women to enhance solidarity and stay true to unified action for the betterment of women, and the society.

Women as Creators and Modifiers of the World

The history of International Women’s Day is a call for rights and justice. Today, the next horizon is to build cultures at home, at work, and society. Women are the creators and modifiers of the world. They are to add color to lives of those around them. In fact, WOMEN, do not need to call for justice, rights and action. WOMEN, need to call the hidden power, strength and courage within them and create a world that assures every being in it receives justice, and enjoys rights.

Thus, whether themes multiply or fade, the test is not in the rally or the ribbon, it is in the 364 days after. The colours may be vivid on stage, yet the colors are faded in practice if we do not live them. Let us re‑design life with dignity, unity, courage, and continuous growth. Let us educate, include, and act justly. Let us awaken strength within, so that every woman, every girl, and every community can thrive by being a Woman Who Re‑designs Life!

Illegal solar push ravages Hambantota elephant habitat: Environmentalist warns of deepening crisis

Published

on

Land earmarked for the project

A large-scale move to establish solar power plants in Hambantota has triggered a major environmental and social crisis, with more than 1,000 acres of forest—identified as critical elephant habitat—cleared in violation of the law, environmental activist Sajeewa Chamikara said.

Chamikara, speaking on behalf of the Movement for Land and Agricultural Reform, said that 17 companies have already begun clearing forest land along the boundaries of the Hambantota Elephant Management Reserve. The affected areas include Sanakku Gala, Orukemgala and Kapapu Wewa, which are known to be key elephant habitats and long-used movement corridors.

He said that what is taking place cannot be described as development, but rather as a large-scale destruction of natural ecosystems carried out under the cover of renewable energy expansion.

According to Chamikara, the clearing of forests has been carried out using heavy machinery, while large sections have also been deliberately set on fire to prepare the land for solar installations. He said that electric fences have been erected across wide stretches of land, effectively blocking elephant movement and fragmenting their natural habitat.

“These forests are not empty lands. They are part of a living system that supports wildlife and nearby communities. Once destroyed, they cannot be easily restored,” he said.

The projects in question include a 50 megawatt solar development undertaken by five companies and a larger 150 megawatt project implemented by 12 companies. The larger project is reported to be valued at around 150 million US dollars.

Chamikara stressed that these projects are being carried out in a coordinated manner and involve extensive land clearing on a scale that raises serious environmental concerns.

He further alleged that certain companies had paid about Rs. 14 million to secure support and move ahead with the projects. He said this points to a troubling failure of oversight by state institutions that are expected to protect forests and wildlife habitats.

“This is not only an environmental issue. It is also a serious governance issue. The institutions responsible for protecting these lands have failed in their duty,” he said.

Chamikara pointed out that under the National Environmental Act, any project of this scale must receive prior approval through a proper Environmental Impact Assessment process.

He said that clearing forest land before obtaining such approval is a direct violation of the law.

He added that legal requirements relating to archaeological assessments had also been ignored. Under existing regulations, large-scale land clearing requires prior evaluation to ensure that sites of historical or cultural value are not damaged.

“The law is very clear. You cannot go ahead with projects of this nature without proper approval. What we are seeing is a complete disregard for legal procedure,” Chamikara said.

The environmental impact of these activities is already becoming visible. With their natural habitats destroyed, elephants are increasingly moving into nearby villages in search of food and shelter. This has led to a sharp rise in human-elephant conflict in several areas.

Areas such as Mayurapura, Gonnooruwa, Meegahajandura and Thanamalvila have reported increasing encounters between humans and elephants. According to Chamikara, more than 5,000 farming families in these areas are now facing growing threats to their safety and livelihoods.

 

He warned that farmers are being forced to abandon their lands due to repeated elephant intrusions, while incidents involving damage to crops and property are rising. There have also been increasing reports of injuries and deaths among both humans and elephants.

“This is turning into a serious social and economic problem. When farmers cannot cultivate their lands, it affects food production, income and rural stability,” he said.

Chamikara also raised concerns about the broader environmental consequences of clearing forests for solar power projects. While renewable energy is promoted as a solution to reduce carbon emissions, he said that destroying forests undermines that goal.

“Forests play a key role in absorbing carbon dioxide. When you clear and burn them, you are increasing emissions, not reducing them. That defeats the purpose of promoting solar energy,” he explained.

He added that large-scale deforestation in dry zone areas such as Hambantota could also affect local weather patterns and reduce rainfall, which would have further negative impacts on agriculture and water resources.

Chamikara called for a shift in policy, urging authorities to focus on more sustainable approaches to solar power development. He said that rooftop solar systems on homes, public buildings and commercial establishments should be given priority, as they do not require clearing large areas of land.

He also recommended that solar projects be located on degraded or abandoned lands, such as areas affected by past mining or other low-value lands, rather than forests or productive agricultural areas.

“Renewable energy development must be done in a way that does not destroy the environment. There are better options available if there is proper planning,” he said.

Chamikara urged the Central Environmental Authority and the Department of Wildlife Conservation to take immediate action to stop ongoing land clearing and investigate the projects. He stressed that all activities carried out without proper approval should be halted until legal requirements are met.

He warned that failure to act now would lead to long-term environmental damage that could not be reversed.

“If this continues, we will lose not only forests and wildlife, but also the balance between people and nature that supports rural life. The consequences will be felt for generations,” he said.

The situation in Hambantota is fast emerging as a critical test of whether development goals can be balanced with environmental protection. As pressure grows, the response of authorities in the coming weeks is likely to determine whether the damage can still be contained or whether it will continue to spread unchecked.
