Importance and relevance of SD:

From a state’s perspective, SD is a subset of national foreign policy and a strategy for advancing its interests and needs. From a global perspective, SD is perceived as a potential solution for tackling common global problems. SD clearly falls within the scope of public policy. It is primarily a lever for action.

Developing economies, mainly in the Southern hemisphere, are home to approximately 80% of the world’s population. However, they started introducing SD only relatively recently, i.e. S. Africa in 2012, India in 2018, Pakistan, 2019 and Columbia 2020. Researchers in the Global South are under-represented as leading authors in research journals, with the result that research produced and scientific methods and techniques developed in the Global South receive lower visibility and are not fully included and well-integrated into “Global Science”. Therefore, SD may provide a framework to acknowledge and address this imbalance in scientific collaboration between regions.

However, unlike countries in the global North, countries in the Global South, barring China and Brazil, find it difficult to post a science attaché in their foreign missions, Hence, the foreign ministry could have a Science Diplomacy Division which liaises between national S&T stakeholders and international partners. It can also call on the services of diaspora and alumni of foreign universities at home and abroad for advancing the national scientific ecosystem.

SD has the potential to play a role in addressing imbalance and global inequalities, i.e. between North and South, through capacity building in scientifically disadvantaged countries, uniting efforts and infrastructure to address global challenges, promoting more inclusive and socially responsible scientific practices across cultures, and promoting science from the “periphery” to the centre of discussions on policy.

Science diplomacy is becoming an important tool by which states can more effectively promote and secure their foreign policy agendas. Recognizing the role science plays at national and international levels and identifying a state’s national diplomatic style can help to construct a ‘national style’ in science diplomacy. SD, therefore, has the potential to influence national audiences in ways that traditional public diplomacy cannot. Thus, SD can be deployed for the following purposes:

Science diplomacy by the government to advance country’s national interests and development

Science diplomacy involving stakeholders to address their real-life issues effectively

Science diplomacy to improve foreign relations and collaborations and to address global challenges

SD to contribute to reducing disparities and inequalities between counties.

SD is neither an all-powerful tool nor a miracle remedy, but it can potentially mitigate conflicts and foster harmony and amity among different communities in a country, and promote friendship among nations. While it has its own limitations, its balanced and inclusive use in international relations could usher in a better tomorrow, making the planet a better place to live in. For all this to happen SD has to be institutionalized and it should also be essentially combined with morality and ethics in order it to be acceptable and effective. History is already replete with examples where SD has been deployed effectively to address global challenges. A few striking examples are given below:

Despite arch rivalry between North Korea and USA, American and British scientists were able to visit even the remotest villages close to the volcano Mount Paektu in N. Korea, following a catastrophic volcanic eruption in 2011, in order to collect rock samples and deploy seismometers. This led to an unprecedented scientific collaboration resulting in joint publications between North Korean and American and British scientists. It was a real boon, showing the potency and power of SD in bringing even archrivals to work together, making the seemingly impossible happen though S&T. It is an example of how technical collaborations can morph into powerful peace and friendship building initiatives. (Figure 1)

Nuclear non-proliferation talks between Iran and USA came to a standstill in 2015 with the atmosphere becoming tense and electrifying. Then Iran nominated Dr. Ali Akbar Salehi, Head, Atomic Energy Organization of Iran, to lead the Iranian team, who in turn requested USA to nominate Ernest J. Moniz, Energy Secretary to President Barack Obama, as his counterpart. Both were alumni of the MIT, USA where they studied nuclear physics. When they came to the negotiating table, politics were put behind and they discussed physics instead, which enabled them to make steady progress. The intervention of science made a huge difference that would otherwise have been next to impossible. Suitably, they were nominated for Nobel Prize in Peace in 2016. (Figure 2)

At the height of the Second World War when fierce fighting was going on between the German troops and British & American troops, German and American scientists and German and British scientists continued to work together not letting the war drive a wedge between them. It shows the profound bonding power of scientific cooperation.

Potential applications of SD to address national issues and regional and global concerns relevant to Sri Lanka

There has been a profound transformation of the Indian Ocean from a mere maritime trade route into a global nexus encompassing security, economic and environmental concerns, social issues and strategic interests. Moreover, international and regional policy discourses on the Indian Ocean regional order, Indo-Pacific dynamics and the Belt-Road Initiative are often sensitive and complex given the intensity of strategic interests and aspirations of some countries in and beyond the region. Here, smaller member-states, particularly when they are economically vulnerable, have no parity when dealing with bigger states that bully them into submission, so that the agenda on cooperation gets submerged by prevailing geopolitical tensions in the Indian Ocean and beyond. Here, SD can be an effective tool to cope with such issues.

Sri Lanka presently occupies the Chair of IORA from 2023 to 2025. Besides, it is a member of BIMSTEC and SAARC. The nature and scope of IORA centre round economic cooperation and on achieving sustained growth and balanced development in the region. Economic cooperation extends to areas such as trade facilitation and liberalisation, promotion of foreign investment, management of marine resources, maritime security, blue economic opportunities, disaster resilience, scientific and technological exchanges, tourism and movement of natural persons and service providers. Therefore, Sri Lanka’s diplomacy needs to rise to the challenge, demonstrating its fullest strength during such discourses in order to navigate the complexities and intricacies involved.

In addition, when bilateral and transborder shared resources such as gas fields, marine resources, fish stocks, rivers and watershed exist, diplomatic efforts without adequate scientific understanding can be ill-directed and counter-productive. This is also applicable to the claimed extended Exclusive Economic Zone of Sri Lanka as per the law of the Sea of Convention. Therefore, a cogent multilateral vision, underpinned by inclusive, coherent policies and combined with a commendable grasp of science diplomacy and consummate skills will be of paramount importance.

Some major issues and concerns to Sri Lanka are briefly outlined below:

Debt restructuring and Climate Change

Sixty one countries in the world face severe debt problems and these debt-distressed countries are unable to make progress towards climate resilience and sustainable development amidst cascading crises and inequalities. “This has not happened because of the bad behavior of one country. This has happened because of systemic shocks that have hit many countries at the same time,” said Rebeca Grynspan, Secretary-General, UNCTAD. With interest rates rising sharply, the debt crisis is putting enormous strain on public finances, especially in developing countries that need to invest in education, health care and their economies, and to adapt to climate change. “To resolve these issues equitably, this needs to be done in a manner that maintains the debtor countries’ ability to grow and meet its current and future debt obligations, while also fulfilling its commitments to the SDGs,” said Sri Lankan President Ranil Wickremesinghe. Debt cannot and must not become an obstacle for achieving the 2030 Agenda and the climate transition that the world desperately needs.

During the COVID-19 pandemic, “Nobody was safe until everybody was safe”. Similarly, unless fair debt relief is provided to debt-distressed countries through interventions such as climate financing, all the countries and peoples in the world, both developed and developing, will be at the receiving end and become victims of climate change. S&T both investigates the underlying causes of climate change and offers remedies for it and other global challenges stemming from human impact. Hence, SD can be applied in an objective and dispassionate manner to address not only climate change, but also other global issues such as pandemics, poverty, water, food and energy insecurity, inequalities, conflicts, pollution etc. which have far-reaching social, political and economic implications and ramifications on humanity as a whole.

National unity

As a result of protracted internecine conflict, the performance of all sectors of the economy of the Northern and Eastern Provinces, including agriculture, fisheries, tourism, cottage industries and SMES were drastically affected. Concomitant with this was loss of livelihood, and means of sustenance of millions of people in those provinces. Therefore, in order to rebuild and resuscitate the regions, it is imperative to revitalize the key sectors affected so as to restore their livelihoods and raise socio-economic standards.

Jaffna has been a Mecca of culture and scholarship as well as a cradle of intellectuals, scholars, scientists and professionals who have made an immense contribution to national development. Similarly, the Eastern Province with a lot of natural endowments and cultural heritage sites possesses immense potentialities for economic growth. The Universities of Jaffna, Vavuniya, Eastern and South-Eastern constitute the brains trust and intellectual pulse of the respective regions. Hence, the universities and R&D institutions in other regions should join forces with them to promote regional development. For instance, with the advent of tsunami in 2004, the University of Ruhuna, with support from CIDA, embarked upon a programme in collaboration with the Eastern University and South-Eastern University in the Eastern province to rebuild and reconstruct the tsunami-affected villages through livelihood development by means of S&T interventions which were quite successful. That led to development of lasting organic linkages among staff of the three universitates which are still robust and vibrant.

Therefore, identification of critical issues in the North in agriculture, fisheries, tourism, etc. and addressing them through such scientific cooperation with the South could contribute to fostering social cohesion, harmony and national unity in the country.

Claim for extended Exclusive Economic Zone

Sri Lanka possesses a territorial sea of 21,500 km2 and an Exclusive Economic Zone (EEZ) of up to 200 nautical miles (370 km) from the coastal line with an extent of 517,000 km2. Sri Lanka has the rights to the resources in the water column, seabed and subsurface in the EEZ. Under the United Nations Convention on the Law of the Sea (UNCLOS), Sri Lanka is entitled to claim for an extended area of seabed where the thickness of the sediment layer exceeds one km. This claim has been made and, if accepted, Sri Lanka could gain an additional seabed area. Therefore, the EEZ is likely to expand further with the delimitation of the outer edge of the continental margin of the country, which would permit Sri Lanka to own an EEZ equivalent to 23 times (approximately 1,400,000 km2) its land mass. Apart from living resources, this Zone contains a variety of exploitable minerals and hydrocarbons (oil and natural gas).

However, given the geo-political and geo-economic interests in the Indian Ocean, when this arbitration claim is taken up by the UN, other nations could also lodge a claim for part of the area claimed by Sri Lanka. Here, not only a profound scientific knowledge of the sediment dynamics in coastal and marine environments, but also consummate skills in SD are required to succeed in the arbitration process.

Potential threats stemming from growing water conflicts in the region

Climate change and the ever-increasing population, combined with growing economic and social imperatives and needs will create competition for water This can lead not only to social unrest and regional conflicts, but also to hydro-political issues, triggering “water wars”. Water insecurity can be weaponized and exacerbate tension and friction within and between countries. Today water is a growing source of global conflict in nearly 50 countries. In Asia, while Sri Lanka is blessed with abundant perennial water resources, many countries are already facing moderate to severe water scarcities.

Water being the lifeblood, its scarcities can trigger conflicts not only between, but also within countries. The historic Mavil Aru battle in 2006 is a telling case in point. Therefore, SD will be of great relevance in coping with potential conflicts emanating from water scarcities in the region. (To be concluded)

We do not want to be press-ganged 

Published

Reference ,the Indian High Commissioner’s recent comments ( The Island, 9th Jan. ) on strong India-Sri Lanka relationship and the assistance granted on recovering from the financial collapse of Sri Lanka and yet again for cyclone recovery., Sri Lankans should express their  thanks to India for standing up as a friendly neighbour.

On the Defence Cooperation agreement, the Indian High Commissioner’s assertion was that there was nothing beyond that which had been included in the text. But, dear High Commissioner, we Sri Lankans have burnt our fingers when we signed agreements with the European nations who invaded our country; they took our leaders around the Mulberry bush and made our nation pay a very high price by controlling our destiny for hundreds of years. When the Opposition parties in the Parliament requested the Sri Lankan government to reveal the contents of the Defence agreements signed with India as per the prevalent common practice, the government’s strange response was  that India did not want them disclosed.

Even the terms of the one-sided infamous Indo-Sri Lanka agreement, signed in 1987, were disclosed to the public.

Mr. High Commissioner, we are not satisfied with your reply as we are weak, economically, and unable to clearly understand your “India’s Neighbourhood First and  Mahasagar policies” . We need the details of the defence agreements signed with our government, early.

When will we learn?

Published

on

At every election—general or presidential—we do not truly vote, we simply outvote. We push out the incumbent and bring in another, whether recycled from the past or presented as “fresh.” The last time, we chose a newcomer who had spent years criticising others, conveniently ignoring the centuries of damage they inflicted during successive governments. Only now do we realise that governing is far more difficult than criticising.

There is a saying: “Even with elephants, you cannot bring back the wisdom that has passed.” But are we learning? Among our legislators, there have been individuals accused of murder, fraud, and countless illegal acts. True, the courts did not punish them—but are we so blind as to remain naive in the face of such allegations? These fraudsters and criminals, and any sane citizen living in this decade, cannot deny those realities.

Meanwhile, many of our compatriots abroad, living comfortably with their families, ignore these past crimes with blind devotion and campaign for different parties. For most of us, the wish during an election is not the welfare of the country, but simply to send our personal favourite to the council. The clearest example was the election of a teledrama actress—someone who did not even understand the Constitution—over experienced and honest politicians.

It is time to stop this bogus hero worship. Vote not for personalities, but for the country. Vote for integrity, for competence, and for the future we deserve.

Chlorophyll –The Life-giver is in peril

Published

Chlorophyll

Chlorophyll is the green pigment found in plants, algae, and cyanobacteria. It is essential for photosynthesis, the process by which light energy is converted into chemical energy to sustain life on Earth. As it is green it reflects Green of the sunlight spectrum and absorbs its  Red and Blue ranges. The energy in these rays are used to produce carbohydrates utilising water and carbon dioxide and releasing oxygen in the process. Thus, it performs, in this reaction, three functions essential for life on earth; it produces food and oxygen and removes carbon dioxide from the atmosphere to maintain equilibrium in our environment. It is one of the wonders of nature that are in peril today. It is essential for life on earth, at least for the present, as there are no suitable alternatives. While chlorophyll can be produced in a lab, it cannot be produced using simple, everyday chemicals in a straightforward process. The total synthesis of chlorophyll is an extremely complex multi-step organic chemistry process that requires specialized knowledge, advanced laboratory equipment, and numerous complex intermediary compounds and catalysts.

Chlorophyll probably evolved inside bacteria in water and migrated to land with plants that preceded animals who also evolved in water. Plants had to come on land first to oxygenate the atmosphere and make it possible for animals to follow. There was very little oxygen in the ocean or on the surface before chlorophyll carrying bacteria and algae started photosynthesis. Now 70% of our atmospheric oxygen is produced by sea phytoplankton and algae, hence the importance of the sea as a source of oxygen.

Chemically, chlorophyll is a porphyrin compound with a central magnesium (Mg²⁺) ion. Factors that affect its production and function are light intensity, availability of nutrients, especially nitrogen and magnesium,  water supply and temperature. Availability of nutrients and temperature could be adversely affected due to sea pollution and global warming respectively.

Temperature range for optimum chlorophyll function is 25 – 35 C depending on the types of plants. Plants in temperate climates are adopted to function at lower temperatures and those in tropical regions prefer higher temperatures. Chlorophyll in most plants work most efficiently at 30 C. At lower temperatures it could slow down and become dormant. At temperatures above 40 C chlorophyll enzymes  begin to denature and protein complexes can be damaged.  Photosynthesis would decline sharply at these high temperatures.

Global warming therefore could affect chlorophyll function and threaten its very existence. Already there is a qualitative as well as quantitative decline of chlorophyll particularly in the sea. The last decade has been the hottest ten years and 2024 the hottest year since recording had started. The ocean absorbs 90% of the excess heat that reaches the Earth due to the greenhouse effect. Global warming has caused sea surface temperatures to rise significantly, leading to record-breaking temperatures in recent years (like 2023-2024), a faster warming rate (four times faster than 40 years ago), and more frequent, intense marine heatwaves, disrupting marine life and weather patterns. The ocean’s surface is heating up much faster, about four times quicker than in the late 1980s, with the last decade being the warmest on record. 2023 and 2024 saw unprecedented high sea surface temperatures, with some periods exceeding previous records by large margins, potentially becoming the new normal.

Half of the global sea surface has gradually changed in colour indicating chlorophyll decline (Frankie Adkins, 2024, Z Hong, 2025). Sea is blue in colour due to the absorption of Red of the sunlight spectrum  by water and reflecting Blue. When the green chlorophyll of the phytoplankton is decreased the sea becomes bluer. Researchers from MIT and Georgia Tech found these color changes are global, affecting over half the ocean’s surface in the last two decades, and are consistent with climate model predictions. Sea phytoplankton and algae produce more than 70% of the atmospheric oxygen, replenishing what is consumed by animals. Danger to the life of these animals including humans due to decline of sea chlorophyll is obvious. Unless this trend is reversed there would be irreparable damage and irreversible changes in the ecosystems that involve chlorophyll function as a vital component.

The balance 30% of oxygen is supplied mainly by terrestrial plants which are lost due mainly to human action, either by felling and clearing or due to global warming. Since 2000, approximately 100 million hectares of forest area was lost globally by 2018 due to permanent deforestation. More recent estimates from the UN’s Food and Agriculture Organization (FAO) indicate that an estimated 420 million hectares of forest have been lost through deforestation since 1990, with a net loss of approximately 4.7 million hectares per year between 2010 and 2020 (accounting for forest gains by reforestation). From 2001 to 2024, there had been a total of 520 million hectares of tree cover loss globally. This figure includes both temporary loss (e.g., due to fires or logging where forests regrow) and permanent deforestation. Roughly 37% of tree cover loss since 2000 was likely permanent deforestation, resulting in conversion to non-forest land uses such as agriculture, mining, or urban development. Tropical forests account for the vast majority (nearly 94%) of permanent deforestation, largely driven by agricultural expansion.  Limiting warming to 1.5°C significantly reduces risks, but without strong action, widespread plant loss and biodiversity decline are projected, making climate change a dominant threat to nature, notes the World Economic Forum. Tropical trees are Earth’s climate regulators—they cool the planet, store massive amounts of carbon, control rainfall, and stabilize global climate systems. Losing them would make climate change faster, hotter, and harder to reverse.

Another vital function of chlorophyll is carbon fixing. Carbon fixation by plants is crucial because it converts atmospheric carbon dioxide into organic compounds, forming the base of the food web, providing energy/building blocks for life, regulating Earth’s climate by removing greenhouse gases, and driving the global carbon cycle, making life as we know it possible. Plants use carbon fixation (photosynthesis) to create their own food (sugars), providing energy and organic matter that sustains all other life forms.  By absorbing vast amounts of CO2 (a greenhouse gas) from the atmosphere, plants help control its concentration, mitigating global warming. Chlorophyll drives the Carbon Cycle, it’s the primary natural mechanism for moving inorganic carbon into the biosphere, making it available for all living organisms.

In essence, carbon fixation turns the air we breathe out (carbon dioxide) into the food we eat and the air we breathe in (oxygen), sustaining ecosystems and regulating our planet’s climate.

While land plants store much more total carbon in their biomass, marine plants (like phytoplankton) and algae fix nearly the same amount of carbon annually as all terrestrial plants combined, making the ocean a massive and highly efficient carbon sink, especially coastal ecosystems that sequester carbon far faster than forests. Coastal marine plants (mangroves, salt marshes, seagrasses) are extremely efficient carbon sequesters, absorbing carbon at rates up to 50 times faster than terrestrial forests.

If Chlorophyll decline, which is mainly due to human action driven by uncontrolled greed, is not arrested as soon as possible life on Earth would not be possible.
