Space Explorations – James Webb telescope

Published

on

By LIONEL PALLIYAGURU

I have been a sky gazer for more than four decades, a habit which started in my school days. As an amateur astronomer, stargazing usually starts from the backyard, with or without any supporting instruments like binoculars or telescopes. Identifications of whatever celestial objects become the first task, with the help of elders who are relaxing in the backyard invariably after supper.

As one develops a keen interest in astronomy, reading and studying astronomy with advanced telescopes become a reality. I have passed many stages in life, and enjoy my retirement life devoting ample time to my hobbies of which astronomy becomes my favourite subject.

It is well known that the James Webb Space Telescope (JWST or WEBB) is in operation with full potential, and incredible photos sent by JWST of distant galaxies could be seen on the NASA website as well as on public media.In order to explore the universe, various projects have been launched by many countries, of which NASA and the European space agency have contributed, by placing complex telescopes operational in outer space.

It is well known that the JWST is the most advanced telescope in operation since July 2022. It is equipped with the most sophisticated instruments with state-of-the-art technologies, and surpasses the capabilities of the Hubble Space Telescope (HST or HUBBLE), which was launched in 1990.

JWST was launched in December 2021 on an Ariane 5 rocket and travelled 1.6 million kilometres in space, to reach its final orbit around the sun, which takes one year to complete one revolution. Whereas its predecessor, HST was launched using Space Shuttle Discovery and placed in a geocentric orbit around the Earth with, an altitude of 547 kilometres at an elevation angle of 28 degrees with the equator. HST takes about 95 minutes to go around the earth and completes 15 orbits per day.

HST is equipped with instruments to probe the composition of the atmosphere of our solar system and extrasolar planets, normally referred to as exoplanets. HUBBLE can capture ultraviolet, visible, and near-infrared wavelengths of light. Although near-infrared radiation is detectable by the human eye, mid and far-infrared regions are less susceptible to the human eye. As the Hubble Space Telescope operates above 547 kilometres above Earth, Hubble can capture visible and infrared spectra with minimum interference.

In order to obtain a high degree of accuracy, space observations should be carried out outside the earth’s atmosphere, where obstruction to visible light and infrared light is minimal. Mathematician Joseph Louis Lagrange has discovered five locations with respect to the sun and earth, where observatories could be parked for various astronomical activities. They are known as Lagrange points and are denoted as L1, L2, L3, L4 and L5. in honour of him.

In these special locations, gravitational and rotational forces cancel each other out, creating ample parking space for telescopes and observatories. Any small mass object placed at the Lagrange point, moves in sync with the Earth, although they are in two different orbits around the sun.

The L2 point is advantageous in many ways for astronomy. The JWST can communicate continuously with Earth while providing a clear view into deep space. Interference from Sun and Earth could be kept to a minimum, as Sun and Earth are behind the telescope. Sun, Earth and L2 points are on a straight line keeping L2 at 151.5 million kilometres away from the Sun and 1.5 million kilometres away from the Earth. To stay in this position minimum station-keeping manoeuvres have to be performed occasionally, which reduces the propellant requirement considerably. As a result, the lifetime of the JWST is increased proportionately.

It took about twenty years to develop the most powerful telescope, costing 10 billion US dollars, in collaboration with the National Aeronautics and Space Administration (NASA), the European Space Agency (ESA), and the Canadian Space Agency (CSA). In addition to the main collaborators, there were about 15 other countries involved and contributed in many ways to making this mission a reality. This astronomical telescope was named as James Webb Space Telescope in honour of James Edwin Webb, who served NASA as an administrator during many critical space missions.

JWST design exceeds all the capabilities of its predecessor, and is expected to uncover the mysteries of the universe, by observing events that have taken place at a distance of 13.6 billion light-years away from Earth. In astronomy, distance is measured in light years. Light-year is the distance that light travels in a year at a speed of 300,000 kilometres per second, which is equivalent to 9.46 trillion kilometres.

Telescopes can go back in time. Looking out in space is looking back in time. Light takes time to travel vast distances in space to reach us. The light from the moon, which is about 390,000 kilometres away from us, takes 1.3 seconds to reach us meaning that we see the moon 1.3 seconds ago. Similarly, light takes about eight minutes to travel from the Sun, which is about 150 million kilometres away from the Earth. Inferring from that, what we see is the Sun about eight minutes ago. When the distances are in the order of billions, light takes years to reach the earth.

JWST is equipped with a) Mid-Infrared Instrument (MIRI), b) Near-Infrared Camera (NIRCam), c) Near-Infrared Spectrograph (NIRSpec), d) Fine Guidance Sensor (FGS), e) Near-Infrared Imager and Slitless Spectrograph(NIRISS). These equipment facilitate measurements of Redshift and Spectroscopy of various objects in the universe such as stars, galaxies, etc. As these instruments monitor the infrared region of the electromagnetic spectrum, all equipment has to be cryogenically cooled to avoid interference within equipment and from outside. The operating temperature is set to minus 266 degrees celsius, which is closer to absolute zero. Absolute zero is minus 273.15 degrees celsius, and the lowest possible temperature to reach. Extremely low operating temperature indicates the unprecedented sensitivity of its infrared equipment.

NASA claims that the sensitivity of infrared equipment onboard the WEBB could detect the heat of a bumblebee at a distance from the moon. Further, details of a small coin of one-centimetre size could be seen at a distance of 40 kilometres away.

In astronomy, redshift has been classified into three categories namely; a) Gravitational, b)Doppler, and c) Cosmological. Redshift is a phenomenon applicable to light sources moving away from an observer. In general, redshift is defined as an apparent increase in the wavelength (or decrease in frequency) of light waves, received from a moving source away from an observer. This is due to the stretching of the wavelength towards the red boundary of the spectrum.

Conversely, when the moving source of light is approaching the observer, a decrease in the wavelength (or increase in frequency) occurs. This is due to apparent compression of wavelength towards the blue boundary of the spectrum known as Blueshift.

Also, when a star rotates, one edge of the star is moving towards us relative to its centre, while the other edge is moving away. As a result, light from one edge of a star is slightly red-shifted, while light from the other edge is slightly blue-shifted. Astronomers can use these two shifts in order to calculate how fast a star is rotating. The same approach can be used to calculate how fast a galaxy is rotating. By evaluating the Redshift, the distance and velocity of any space object could be calculated. Conversely, Blueshift provides parameters of distance and velocity of an approaching object.

Astronomical spectroscopy is mainly concerned with the analysis of objects such as stars, planets, nebulas, and galaxies in space. It is done by splitting the received infrared spectrum into its various wavelength components. The spectrum patterns of a star can be compared with known spectrum patterns of hydrogen, oxygen, carbon and other elements to determine the physical and chemical composition of the star.

The media has shown magnificent and colourful photos of various stars, galaxies and nebulas released by NASA. Anybody would wonder about the process of producing such stunning photos from faraway galaxies many light years away from the Earth. These images are captured using infrared cameras and the spectrum is split into many different frequency bands using filters. Different colours are assigned to each frequency band during processing to obtain spectacular photos. A similar process is being used in digital colour cameras in processing visible light photos.

James Webb Space Telescope is expected to function at full capacity for a minimum of 10 year period. Scientists and Astronomers work tirelessly to explore discoveries of our universe, and life beyond our Earth, which is one of the key objectives of this mission.

The Republic is 54: Towards a Third, “System-changing” Republican Constitution

Published

on

Aragalaya

by (Dr) Jayampathy Wickramaratne President’s Counsel

Sri Lanka’s constitutional journey remains marked by unresolved dilemmas: entrenched executive dominance, fragile fundamental rights, unfulfilled reform promises, and the persistent national question. These challenges have deepened inequality, strained ethnic relations, and weakened democratic accountability. The writer argues that constitutional supremacy must be firmly secured above transient political majorities, with judicial review extending to all acts of the State, including those of Parliament. Central to this vision is the abolition of the executive presidency, whose concentration of power has undermined Parliament and diminished popular sovereignty. Equally vital is the adoption of a modern bill of rights that safeguards equality, social justice, and human dignity and is enforced by an independent judiciary. Devolution of power is presented not as a concession but as a constitutional necessity—indispensable for unity in diversity and for laying the foundations of ethnic peace.

Based on the reports of the Steering Committee and the sub-committees of the 2015-2019 constitutional reform process, one could say that if a constitution had materialised, it would have been somewhere between a “reformist” and a “transformative’ constitution. On the other hand, if the 2000 Constitution Bill had been passed, the new constitution would have been a “transformative” one. On the 54th anniversary of Sri Lanka’s declaration as a Republic, the writer calls for a Third Republican Constitution that should be “transformative” rather than merely “reformist”.

The significance of the Aragalaya

Much has happened since 2000. The separatist war is over, but the ethnic conflict persists. The Aragalaya protest of 2022 marked a historic citizen-led uprising against authoritarianism, corruption, dynastic rule, and economic mismanagement, and was a turning point in the country’s democratic struggle. It symbolised the reclaiming of public space, the demand for accountability, and the assertion that ordinary citizens—especially youth—could challenge entrenched political dynasties. How should the new constitution respond to these developments?

The Aragalaya’s core significance lies in its role as a democratic awakening, in which ordinary citizens, transcending ethnic and class divides, reclaimed public space and demanded accountability from entrenched elites. It symbolised the rejection of corruption, nepotism, and unchecked executive power, while affirming the capacity of grassroots, youth-led mobilisation to force systemic change. As a basis for a new constitution, the Aragalaya underscored the urgent need to embed constitutional supremacy, end executive dominance, secure judicial independence, and strengthen institutional accountability—ensuring that sovereignty truly rests with the people and that governance cannot again be monopolised by dynastic or authoritarian rule. The Aragalaya fostered unprecedented solidarity among Sri Lanka’s diverse communities; it created bonds across ethnic and religious lines, making it far more difficult today for divisive forces to rekindle communal or sectarian hatred.

Aragalaya

directly shaped the 2024 elections in Sri Lanka by delegitimising dynastical rule, energising youth and civil society, and embedding demands for accountability and constitutional reform into the electoral agenda. The protests created the political climate in which voters decisively rejected continuity and sought leadership promising systemic change.

NPP Victory in 2024

In 2019, Janatha Vimukthi Peramuna (JVP) formed a coalition called the National Peoples Power (NPP) with more than twenty organisations, including political groups, youth organisations, women’s groups, trade unions, and civil society organisations. Although it did not fare well in the 2019 Presidential elections and the 2020 Parliamentary elections, it was the primary beneficiary of the unprecedented protests against the political establishment in the wake of the massive economic crisis in 2022, which culminated in President Gotabhaya Rajapaksa fleeing the country and resigning.

In the 2024 Presidential election, Anura Kumara Dissanayake of the NPP secured 42.31% of the vote in the first round. In the second round, preference votes from candidates outside the top two—Dissanayake and Sajith Premadasa of the SJB—were redistributed, and Dissanayake secured 55.89% of the combined tally and was declared the winner. Upon assuming office, President Dissanayake promptly dissolved Parliament. The subsequent election delivered a historic outcome: the NPP captured 61.56% of the vote and 159 of 225 seats, granting the party a decisive two-thirds majority to pursue constitutional reform.

In its election manifesto, the NPP pledged to introduce a new Constitution. Notably, the NPP committed to completing the 2015-19 constitutional reform process early. The main features of the Constitution would be a parliamentary form of government to replace the executive presidency, a new electoral system, fundamental rights to include economic, social, and cultural rights, rights of women, children, and the disabled, as well as “devolution of political and administrative power to provinces, districts, and local government units.”

The NPP’s main rival, the SJB, also committed itself to changing the present Constitution and formulating a new Constitution that would convert the form of government to a parliamentary system, include economic, social, and cultural rights, and provide maximum devolution based on the Thirteenth Amendment within a single country.

A transformative, “system-changing” constitution

How should a new constitution respond to the people’s cry during the “Aragalaya“, reiterated at the 2024 elections?

In essence, the Aragalaya’s cry for system change should translate into a constitutional framework in which sovereignty genuinely rests with the People and institutions are resilient against authoritarian capture. The new constitution must affirm that all power flows from the people and is exercised in trust, with accountability and in accordance with justice. Recognising the dangers of unchecked authority, corruption, and dynastic rule, there must be a clear commitment to a constitutional order that safeguards democracy, ensures transparency, and protects the independence of institutions.

The above can be realised only through a “transformative constitution” committed to “system change”, not a mere “reformist constitution”. The essentials of such a constitution lie in recognising that it is not a static text but a dynamic, evolving framework of governance. It must enable courts to interpret constitutional provisions in ways that respond to contemporary realities and advance justice and equality. A new constitution must therefore embody a strong commitment to social justice, requiring the state to dismantle systemic discrimination and ensure fairness and dignity for marginalised communities. Its legitimacy must also rest on participatory democracy, with citizens playing an active role in shaping institutions and contributing to the ongoing development of the constitutional order. Above all, a new constitution must be understood as a living instrument—capable of adapting to changing social, political, and economic conditions while remaining faithful to democratic values and fundamental rights. In this sense, the purpose of constitutionalism is not merely to preserve constitutional order but also to promote justice, equality, inclusion, and meaningful democratic engagement in a changing society.

Sri Lanka requires a modern, comprehensive bill of rights capable of addressing contemporary challenges, including equality, social justice, and human dignity. Rights must be real and enforceable rather than merely aspirational, and their protection depends on an independent and courageous judiciary. Likewise, devolution of power must be understood not as a political concession but as a constitutional necessity to empower the people at all levels. In a pluralist society, meaningful power-sharing is indispensable for preserving national unity while respecting diversity and for laying the foundations for ethnic peace.

Supremacy of the Constitution

The supremacy of the Constitution should be the cornerstone of any truly transformative constitutional order. In the Sri Lankan context, it should mean that no state institution, nor any individual, family, or political party, can place itself above the law or manipulate institutions for personal gain. A transformative constitution must therefore enshrine the principle that all state power derives from and is limited by the Constitution, and that any act inconsistent with it is void.

To achieve this, the new Constitution must, at a minimum, provide that any law, subordinate legislation, or conduct inconsistent with its provisions is void, thereby affirming constitutional supremacy. It should guarantee unlimited judicial review of legislation, ensuring that no enactment escapes scrutiny. All existing laws must be interpreted subject to the Constitution, including the fundamental rights, unlike under the 1972 and 1978 Constitutions. Furthermore, all actions of Parliament, whether legislative or otherwise, must remain subject to judicial review. Finally, the jurisdiction of fundamental rights should extend to all actions of the state—legislative, executive, judicial, and otherwise—as well as to conduct by non-state actors, thereby securing comprehensive accountability under the constitutional framework.

An unalterable basic structure

Soon after a parliamentary election, the governing party often enjoys strong prospects of winning a referendum. But does this mean that a twothirds majority in Parliament, combined with 50% plus one of the People, can impose any constitution? Could it, for example, deny the freedom from torture to suspected terrorists or entrench oneparty rule? In the absence of entrenched safeguards, the risk of such perilous constitutional changes remains unchecked.

Sri Lanka’s constitutional reform process should pursue a carefully balanced approach to entrenchment. Provisions that safeguard foundational principles are essential to guard against abusive or opportunistic amendments. However, such protections must be drafted with precision and restraint. If entrenchment is framed too broadly, it can immobilise detailed or technical provisions, resulting in excessive rigidity and weakening the Constitution’s capacity to adapt to evolving democratic realities.

The most effective protection lies in a dual framework: confining entrenchment to the Constitution’s core identity while simultaneously empowering the judiciary to scrutinise constitutional amendments against those basic principles. This approach secures permanence where it is most necessary while preserving flexibility in other areas of governance. For Sri Lanka, the central lesson is that constitutional stability should not be achieved at the cost of democratic adaptability. A thoughtfully calibrated combination of narrowly defined entrenchment and principled judicial review provides the most reliable foundation for a constitutional order that is both resilient and responsive.

The writer submits that a future constitution should contain a set of basic principles that form an unalterable basic structure. On the eve of the 2024 Presidential elections, the Collective for Democracy and Rule of Law, a group of academics and professionals, proposed that a set of ‘Constitutional Principles’ be included in a new Constitution. They should be described as ‘immutable and inviolable values of democratic republicanism.’ These principles will embody the fundamental constitutional values that guide the new Constitution and future judicial interpretation of its clauses. The Collective proposed that the Constitution should recognise the following immutable and inviolable values of democratic republicanism and consociationalism: human dignity, social justice, economic justice, equality and the advancement of human rights and freedoms; ethnic, gender and social equality; the supremacy of the Constitution and the Rule of Law; regular, uninterrupted, free and fair elections and a multi-party system of democratic government; non-concentration of state power in one individual or institution; the assurance of accountability, responsiveness and transparency at all levels of governance; public authorities hold and exercise powers in accordance with the doctrine of public trust. The writer submits that the above principles could form the basis for an unalterable basic structure.

The NPP government was entrusted with a clear mandate to dismantle authoritarian structures and deliver constitutional reform, yet its continued inaction betrays that trust. Sri Lanka cannot afford further delay, for every day without reform entrenches executive dominance and erodes public faith in democracy. What is needed now is decisive action to abolish the executive presidency, entrench constitutional supremacy, advance devolution, and pave the way for social justice, so that sovereignty genuinely resides with the people and the promise of a just, democratic republic is finally realised.

Mattala Airport, wildlife and possible solution

Published

on

View from the ‘Ark’ Kenya, Africa

The Island of 20 May revealed the possible Indian investment in the ‘loneliest Airport In the world’.

Will the proverbial camel put its head inside the tent?

This effort could be compared to flogging a dead horse!

Your report mentions that Mattala Airport is an ideal place for a flying school.

The sad fact is that no wind pattern and turbulence studies have been carried out in the area. The turbulence is so great that even large passenger aircraft find the approach to land extremely turbulent.

In the same issue of The Island, another report by Ifham Nizam, on the Human-Elephant conflict at Hambantota says an’ Elephant Management Reserve’ is essential for Hambantota. The real reason for that is no secret. It is due to the displacement of elephants from their natural surroundings.

Read the whole story of Mattala Rajapaksa International Airport (MRIA) below. It is an extract from a book, titled ‘From Nose to Tale’ By Captain Gihan A. Fernando, published last year.

 ‘Mattala: A Mistake?’

 “Many years ago, when an alternative international airport to Colombo-Bandaranaike International (BIA), Katunayake was mooted, the Air Ceylon Pilots’ Guild began lobbying for China Bay, Trincomalee. Among other considerations, it was pointed out that because Sri Lanka is subject to both the Southwest and Northeast monsoons, at each of those seasons the coast on the opposite ‘quadrant’ of the island would generally be experiencing good weather, and vice versa.

 But the guild’s request came too late, as the Sri Lanka Air Force (SLAF), which has a base at China Bay, had already stated that they had no objection for tall silos to be built at the site of the Prima flour mill, along the take-off and landing paths of China Bay’s single runway.

 Another site was then suggested, near Nilaveli, 20 miles north of Trincomalee. In the 1970s, Nilaveli was fast developing into a popular tourist location. But that idea of a new airport was also dropped when Eelam separatist rumblings first began as early as 1978 when an Air Ceylon HS 748 on the ground at Ratmalana Airport was destroyed by a terrorist’s bomb, fortunately without injuries to anyone or loss of lives (Chapter 17).

 The need for an alternative international airport in Sri Lanka was driven by a requirement by Ceylon’s then Air Navigation Regulations (ANR) for all airliners destined for BIA. In the event of being unable to land there for one reason or another, they must be carrying sufficient fuel to reach Madras (Chennai), the nearest ‘alternative’ to BIA that could accept large jets, plus fuel for another half-hour in the air. Establishment of a second international airport would obviate that burdensome necessity.

 However, all aircraft ‘burn fuel to carry fuel’. For example, if an aircraft needed to have 10,000 kg of fuel onboard to comfortably reach BIA, based on flying time for that particular sector, the crew would have had to uplift 12,000 kg at the point of departure. Put simply, if a closer alternative airport was available, carrying less fuel would be a saving.

 The ANRs of developed countries have been progressively updated to keep pace with advances in aviation, yet in Sri Lanka supplementary regulations to ANRs promulgated in 1955 remain in force.

 When Air Lanka began operating Lockheed L-1011 TriStars, the first few were obtained from Canada. Accordingly, the airline followed operational procedures laid down by Air Canada in the Canadian operations manual. One such statement was that it was not necessary to always have fuel onboard to reach a designated alternate airport as it permitted the captain to arrive at the destination with a lesser amount of fuel, provided the destination airport predicted good weather and had at least two runways [author’s emphasis].

 The theory behind the Canadians’ thinking was that even if one runway becomes unusable for whatever reason, a second was available as a fall-back. Interestingly, even today, when a new airline requests permission from the Civil Aviation Authority of Sri Lanka (CAASL) to operate to BIA, they must show that it can remove a disabled aircraft as soon as possible, so as not to obstruct the single runway leaving it unserviceable for an unduly protracted period.

 When the runway at BIA was becoming outdated, having been constructed with Canadian aid and expertise in the late 1960s, it was decided that a new one should be constructed, this time with aid from Japan. The plan was for it to be built parallel to and north of the existing runway, with the latter narrowed and converted to a taxiway. That was when the Air Line Pilots’ Guild of Sri Lanka (ALPGSL) made representations to General D. Sepala Attygalle, secretary to the Ministry of Defence under whose purview Air Lanka was administered. They requested Attygalle to retain the old runway as a second runway, so that the requirement to carry extra fuel during times of good weather would no longer apply.

 Separately, an expert from the International Civil Aviation Organization (ICAO) declared that the new and taller air traffic control tower was too close to the old runway, making its use illegal. On the other hand, what pilots wanted was a runway that would be used in ‘one-off’ situations, not on a regular basis. However, those plans didn’t proceed, and the status quo prevailed.

 Another suggestion was for an international airport at Hingurakgoda, site of the present domestic and military Minneriya airfield. With Australian financial aid promised, there was a strong possibility of that proposition becoming reality. In fact, Singapore Airlines began drawing up Boeing 747 performance charts for use at the proposed new Hingurakgoda International Airport. However, some decision-makers believed that the estimated costs, based on Australian labour rates, were too high. Other critics pointed out that the same weather patterns affecting BIA would prevail at Hingurakgoda too. Eventually, that idea was also scrapped.

 Then the SLAF decided to move its jet-fighter base to Sigiriya airport which, after extension, could have also accepted big passenger jets diverting from BIA. However, the Department of Archaeology objected to that move on the grounds of noise and vibration produced by jet engines adversely affecting the structure and amenity of Sigiriya Rock.

 In response, Sri Lanka’s then President Chandrika Bandaranaike Kumaratunga granted the Director of Archaeology, Dr. Roland Silva, and chairman of the Urban Development Authority, Mr. Gemunu Silva, an eminent civil engineer, the use of a SLAF Bell 412 helicopter for two weeks, to travel to all parts of the island looking for a suitable location for an alternative international airport. The pair identified a potential 250-acre site within the triangle formed by Kekirawa, Dambulla and Habarana, consisting mostly of crown land requiring no major acquisition from resident farmers. A report was submitted to the president, but nothing eventuated from that exercise.

 Second Runway at BIA

Meanwhile, many experts declared that the best option was indeed to construct a second runway at BIA. Accordingly, an extensive study was conducted by the International Air Transport Association (IATA) in conjunction with Dayantha Athulathmudali, a former deputy director of CAASL. They took into consideration such diverse factors as: the proximity to the Attanagalu Oya; relocating the SLAF base from Katunayake to another site; the effect on the Free Trade Zone (FTZ); and how the many churches and temples in the area may be affected. The primary question was whether the new, second runway, aligned parallel to the existing one (built with Japanese aid), should be situated north or south of it.

 Going Down South

But before any decision on the future of expansion at Katunayake was made, it was announced by the then secretary to Ports and Civil Aviation that three potential sites in the Hambantota District were under consideration: Udamaththala, Gonnoruwa and Weerawila. Already, in 2007, an Environmental Impact Assessment (EIA) was conducted on behalf of Airport and Aviation Services (Sri Lanka) Ltd (AASL), on behalf of the Central Environmental Authority (CEA), by the Central Engineering Consultancy Bureau (CECB). The report stated that as there was already an airport at Weerawila, it was the most cost-effective location for the second international airport, and therefore the preferred of all three options examined.

 When it was eventually announced that the second international airport would be built at Weerawila, many aviation ‘experts’ wrote to the newspapers claiming that the government had its priorities mixed, and that the best option was, still, to build a second runway at BIA. One writer even said that Weerawila is “one of the best examples of an ill-conceived project and chronic waste of tax-payers’ money.”

 Similar sentiments were expressed in 1975, when the Canadian government built a new airport at Mirabel in Montreal to cater to the 1976 Olympics in that city. But after the Olympics, and for a variety of other economic reasons, Montreal-Mirabel Airport gradually fell into disuse over the next 27 years. In Sri Lanka, concerned parties believed that Weerawila would suffer an identical fate.

 When farmers discovered that the officially preferred site was Weerawila, and that their paddy lands would have to be acquired, organisations representing them resorted to legal action, forcing the government to revert to its second preference, Udamaththala, 13 km from Weerawila. Accordingly, 800 hectares (almost 2,000 acres) were cleared, and 44,000 hardwood trees chopped down on land that largely comprised elephant habitat. Although it was widely known that this site was in the middle of an elephant corridor, no-one protested – at least not immediately.

 Yet the chairman of the Central Environmental Authority (CEA) subsequently said: “Since there was no objection from stakeholders, we gave permission to the Mattala project. I refute the allegations levelled against this institution by the environmentalists. Those allegations are made to mislead the people.”

 The Mattala airport project started in 2009, but airline pilots, the ‘end users’, were not consulted. Nor was there any serious aeronautical or environmental research. For example, no wind studies were carried out, contrary to ICAO recommendations that before construction of a new airport commences a wind study must be conducted for at least five years, with readings taken at least eight times daily at frequent intervals. ICAO also stipulates, in Annex 14 to the ICAO Convention, that the potential for turbulence must be studied too. CAASL officers neither knew nor cared to determine the locations relative to each other of the proposed airport, Bundala Bird Sanctuary, and Yala National Park.

They even lacked a detailed map of the area, despite the author having donated a 1:50000 map to the CAASL.

 In March 2007 the Sri Lanka Aeronautical Society (SLAeS) was formed to primarily serve as a think tank on aviation matters, with all aspects coming under its purview. When the first president of the SLAeS, who was an airline captain not working in Sri Lanka, pointed out the embarrassing truth that Mattala was going to be a bad investment, and that it was SLAeS’s duty to make it known, his warning was not well received by CAASL officials. Instead, because the Mattala airport project had to proceed at all costs, a parallel association was formed to take over some of the functions of the SLAeS with a view to deliberately shutting down the latter body – which soon happened. Sadly no-one, including officers of CAASL, was bold enough to speak up for fear of incurring the ire of political forces driving the establishment in that location of what would be named Mattala Rajapaksa International Airport (MRIA).

 So much so that in 2017, by which time the viability of MRIA was shown to be far below expectations, the aviation minister declared to members of CAASL: “You people never told us”. In other words, claiming not to have been forewarned of what a farce the new, grossly under-utilised airport would turn out to be.

 But there were other acts of omission. In fairness to CAASL, in 2007 its management was in a fluid state. The CAASL chairman’s contract hadn’t been renewed, and the director-general had taken leave of absence from CAASL as he had had a difference of opinion with the then chairman of Mihin Lanka, the newly formed government-backed regional airline. Consequently, CAASL officials were all acting in other capacities.

 Nowadays at Mattala the air is often extremely turbulent on final approach, and it is a struggle even for pilots of big jets who occasionally fly in there. On some days lighter aircraft are also unable to land due to turbulence. Ironically, today the same farming organisations which took out an interim injunction on development of the Weerawila airport are affected by elephants displaced from the Mattala precinct.

 Creating further environmental disruption and damage, trees at the future site of Mahinda Rajapaksa International Cricket Stadium, another grandiose government project built at Sooriyawewa in the Hambantota District, were felled in the name of progress. That stadium has also been rarely used for its intended purpose, and fallen into neglect and deterioration.

 According to Nirmala Kannangara writing in the Sunday Leader, the Director of the Environment Conservation Trust, Sajeewa Chamikara, is reported to have said: “All attempts to educate the Aviation Ministry of the consequences that have to be faced in future when plans were drawn to construct an international airport at Mattala were ignored. Since this area is populated with migrant birds throughout the year, we told the government to shift the location to a place with less vulnerability, but their failure to listen to us has now brought several consequences.” Mr. Chamikara’s warnings were supported by many leading professionals who also wrote about the dire consequences to aircraft, passengers and crew in the event of bird strikes.

 But building a new airport, suitably located or otherwise, is not the end of the process. The airport authority must continuously maintain it, at great expense. High safety standards must be met in a multitude of areas, not least aircraft inspection, servicing, overhaul and repair.

 All components of its infrastructure require constant attention, for example such items as: maintenance of landing visual aids; provision of spare parts; adhering to a lighting maintenance schedule for general and basic maintenance of approach, runway and taxiway lighting systems; aircraft docking systems including their specific light maintenance procedures; cleaning procedures for lights; light intensity measurements; removal of water (condensation); maintaining signs and painted markings. Painting runway centre lines alone requires more than 1,000 gallons of white paint.

 Runway and tarmac surfaces need constant maintenance and repair, with attention paid to joints and cracks in concrete and bituminous pavements. ‘Gardening’ activities must be undertaken regularly to keep grass and other unpaved areas neat and free of excess growth. Building maintenance must encompass such aspects as lighting and other electrical equipment, communication facilities, air conditioning systems, automatic doors, baggage conveyor belts, baggage claim units, passenger boarding bridges, people lifts (elevators), people movers (escalators and travelators), fixed fire protection installations. Not least, conducting regular safety meetings. The list goes on.

 In view of the above, the question must be asked: did the authorities get their priorities mixed up? Their rationale for MRIA’s creation and existence to earn revenue as an emergency refuge for overflying traffic between two other destinations is no more than a myth. BIA can satisfy the same requirement. Apart from a second runway at BIA, the focus should have been on improving domestic air services, for locals and tourists, by developing existing airports, or creating new facilities, at Jaffna, Batticaloa and Weerawila.

 It has to be said, though, that Jaffna has since attained the status of an international airport, as have Ratmalana and Batticaloa, with planning already underway for Hingurakgoda to join Sri Lanka’s multitude of ‘international gateways’, taking the total to six. Yes, count them – six international airports on an island the size of Tasmania, Australia. Overkill? Political grandstanding? Parochialism? Nest-feathering? You be the judge.

 At the time of writing, 11 years have elapsed since the MRIA ‘white elephant’ was commissioned, yet it continues to suck up taxpayers’ money better than any leech could. Today’s crop of so-called ‘aviation experts’ are unable to come up with an acceptable solution to turn MRIA into a profitable enterprise. Meanwhile, people in high places with vested interests in and ‘connections’ with the regime that built that wasteful airport in the first place continue to sing its praises while suggesting possible alternatives for using MRIA as an aviation ‘hub’. But that is nothing more than pie in the sky. Or like the emperor’s new clothes in the folktale by Hans Christian Andersen.

 So, while MRIA’s runways see more use by trespassing elephants – across whose traditional migratory path the airport violated – than airliners with fare-paying passengers, the question must be asked: what can be done with MRIA? Will the chairman and director-general of CAASL, in conjunction with AASL and environmentalists be able to resolve this expensive problem and face the situation squarely? Or will the nation have to wait even more years for a satisfactory solution than it took for the stewards of Mirabel International Airport, Montreal, Quebec, Canada? “

 A reasonable solution for Mattala Rajapaksa International Airport

Flying has been this Seeya’s life for over fifty years and he never thought he would be saying this. In Kenya, there is a hotel in the jungle called ‘The Ark’, built near a waterhole where all kinds of animals come to drink, day and night. There are flood lights trained on to the water hole at night. There are animal spotters who activate buzzers in the hotel rooms, depending on the type of animal. The visitors could come to large viewing areas to watch them. The Airport and Aviation Sri Lanka, the Tourist Industry and the Wild Life Conservation Department could remove the electric fencing and reopen the waterholes that were closed to prevent birds from nesting and in short throw it open to the elephants again. There is also an airport in Ecuador, which has been turned into a park. The terminal building has large glass windows that would be great for viewing and photographing elephants. A large water hole by the parking apron could attract more elephants. The Control Tower could be used for elephant spotting. Converting Mattala into a Tourist Hotel will create a money spinner. Let us ‘Bite the bullet’ and cut our losses in these difficult times. As experts say “Mistakes pave the way for innovation, growth and creativity”

The best radio navigational and landing aids have been installed at Mattala and remain largely unused, while Ratmalana, the cradle of Civil Aviation, remains technically deficient. AASL could therefore reinstall some of the Mattala navigational aids like the Very High Frequency Omnidirectional Range/ Distance Measuring Equipment (VOR/DME) and the Instrument Landing System (ILS) at the Colombo International Airport, Ratmalana, at minimum cost. The other ILS could be installed at KKS, Batticaloa or Weerawila airports which also lack Navigational Radio aids.

The Human-Elephant conflict could be greatly resolved if Mattala and Suriya Wewa are given back to the jungle. The SLAF could initiate intense seed bombing to replace the 44,000 trees that were cut. It may take hundreds of years to recover. Let us forget our egos and think out of the box. After all, to ‘Err is human’ (Cicero).

Depreciation of the Rupee: A Warning Sign of Sri Lanka’s Deep Economic Crisis

Published

on

The gradual depreciation of the Sri Lankan rupee is one of the most serious economic signals facing the country today. It is not merely a change in the exchange rate. It is a powerful reflection of a nation’s economic strength, fiscal discipline, investor confidence, political stability, and the future hopes of its people.

When a country’s currency loses value, it indicates deeper weaknesses in production capacity, foreign exchange earnings, economic management, and institutional credibility. In this sense, the depreciation of the rupee is not an isolated financial issue. It is a factor that further deepens Sri Lanka’s already fragile economic, social, and political crisis.

Only a few years ago, around Rs. 130 or Rs. 150 was sufficient to buy one US dollar. However, during the 2022 economic crisis, the exchange rate exceeded Rs. 360 per dollar at certain points. Although some stability has returned since then, it would be misleading to say that the real strength of the rupee has been fully restored. The simple meaning is this: Sri Lanka now needs far more rupees than before to import essential goods such as fuel, medicine, food, machinery, and raw materials.

Inflationary Pressure in an Import-Dependent Economy

The first and most direct consequence of rupee depreciation is the increase in the general price level of goods and services. In other words, it fuels inflation. Sri Lanka remains an economy that depends significantly on imports. According to World Bank data, in 2024, imports of goods and services accounted for around 22.5% of Sri Lanka’s Gross Domestic Product.

Therefore, whenever the rupee weakens, the cost of imports rises. Fuel prices increase. Transport costs go up. Industrial production costs become higher. Eventually, this burden falls directly on the daily lives of ordinary people.

In September 2022, inflation in Sri Lanka, measured by the Colombo Consumer Price Index, reached 69.8%, while food inflation climbed to 94.9%. These were not just numbers. They represented real suffering in family food budgets, children’s education, healthcare expenses, and the living standards of the middle class.

As a result, poverty also increased. According to World Bank estimates, urban poverty rose to 15% in 2022, while rural poverty increased to 26%. The data also showed that more than half of the population in estate communities lived below the poverty line.

The Silent Crisis of Fixed-Income Earners

Those most affected by rupee depreciation are people who depend on fixed salaries. Their income may remain the same in numerical terms, but its real purchasing power continues to decline.

A person earning Rs. 100,000 per month today finds it extremely difficult to maintain the same standard of living that was possible a few years ago. The rising cost of food, housing, education, healthcare, and transport has weakened the middle class at an alarming rate.

This situation can be described as “working poverty.” A person may be employed, yet unable to maintain a dignified standard of living from that income. This is a serious threat to social stability, because in any country, a strong middle class is one of the main foundations of social balance and national resilience.

The Collapse of Youth Hope and the Outflow of Human Capital

This economic pressure also damages the hopes of the younger generation. When young people begin to lose faith in the idea that education, effort, and talent can help them build a future within their own country, they naturally begin to think of leaving the country instead of helping to rebuild it.

According to the Sri Lanka Bureau of Foreign Employment, 310,948 people left for foreign employment in 2022. By December 13, 2024, the number had again risen to 300,162. In the first six months of 2025 alone, 144,379 people had left for foreign employment.

In the short term, this may increase foreign exchange earnings through remittances. However, in the long term, it creates a serious challenge for the country. When skilled doctors, engineers, IT professionals, technicians, professionals, and graduates leave in large numbers, Sri Lanka’s human capital, innovation capacity, and productive strength are weakened.

External Debt and the Fiscal Crisis

The depreciation of the rupee also has a serious impact on public finance. A large share of Sri Lanka’s external debt is denominated in US dollars. Therefore, when the rupee weakens, the amount of rupees required to repay the same dollar debt automatically increases.

For example, when the exchange rate is Rs. 200 per dollar, a debt of USD 1 billion is equal to Rs. 200 billion. But if the dollar rises to Rs. 300, the same debt becomes Rs. 300 billion. This shows how the debt burden can increase even without taking new loans, simply because the rupee has weakened.

According to Treasury debt data at the end of 2024, Sri Lanka’s total external debt was around USD 36.7 billion. IMF data also shows that Sri Lanka’s public debt stood at 125.8% of GDP in 2022. Although it declined to 105.7% in 2024, it still remains at a very high level.

In such a situation, the government is often forced to increase taxes, reduce public expenditure, and limit essential services. This again weakens living standards, increases the cost of doing business, and reduces confidence in the economy.

From Economic Crisis to Political Crisis

People often see the collapse of a currency as a symbol of government failure. When the cost of living cannot be controlled, when the tax burden rises, when job opportunities decline, and when uncertainty about the future grows, public confidence begins to collapse.

The 2022 “Aragalaya” is a powerful example of this. It was not merely a political protest. It was a moment when an economic crisis transformed into a social and political crisis. When economic pressure increases, people are often drawn towards populist politics that promise quick and simple solutions. In such an environment, short-term popular decisions can easily take priority over long-term reforms.

The Root Problem: A Weak Economic Structure

It is not enough to understand the depreciation of the rupee merely as an event in the foreign exchange market. It is a warning sign of deep structural weaknesses in Sri Lanka’s economy.

For decades, the country has depended more on consumption than production, more on imports than exports, and more on borrowing than income generation. Political decisions were often shaped by short-term popularity rather than sound economic reasoning. The result is the structural crisis Sri Lanka faces today.

What Should Policymakers Do?

This problem cannot be solved through temporary monetary controls alone. Spending foreign reserves to artificially defend the rupee is not a sustainable long-term solution. What Sri Lanka needs is to give the rupee a real economic foundation.

For that, policymakers must focus on increasing export earnings, strengthening import-substitution industries, maintaining fiscal discipline, broadening the tax base in a fair manner, and creating a stable policy environment for foreign investment.

Sri Lanka should not continue to depend only on tea, garments, tourism, foreign employment, and traditional service exports. The country must build new sources of foreign exchange through information technology, professional services, value-added agriculture, pharmaceutical production, light manufacturing, higher education services, and innovation-driven enterprises.

At the same time, corruption must be controlled, public institutions must regain credibility, policy consistency must be protected, and the business environment must be simplified. The stability of the rupee cannot be secured through Central Bank interest rate policy alone. It requires rebuilding the productive economy, export capacity, fiscal credibility, and public confidence.

The depreciation of the rupee is not merely a decline in the value of money. It is a mirror that reflects the economic strength, political quality, and social confidence of the nation.

Protecting the rupee does not mean artificially controlling the exchange rate. It means rebuilding the country’s productive strength, institutional credibility, fiscal discipline, export capacity, and the future hopes of its people.

Sri Lanka’s real challenge lies there. The rupee becomes strong when the economy becomes strong. The economy becomes strong when the country produces. The country produces when people, businesses, and investors have confidence in the future. Rebuilding that confidence must become one of Sri Lanka’s most urgent national priorities.
