No answer to why Sinhalese solicitor split his original name into two

Little did William Alfred Goone Tilleke know when he stepped ashore Siam in 1890 that he would create a law firm that would endure for over 130 years.

In 1890, William Alfred Goone Tilleke, a 31-year-old Singhalese solicitor, came to Siam (now Thailand) to build his legal career. Within four years, Tilleke made an international name for himself through his successful defense of the Siamese military commander Phra Yod Muang Khwang, whose prosecution for killing a French officer was demanded by the Franco-Siamese treaty.

Through the early twentieth century, the firm was stewarded by several British partners, including Ralph Gibbins, Samuel Brighouse, Reginald Atkinson, and Victor Jaques. Like Tilleke, each partner played a key role not only in the firm’s success, but also in the development of the Thai legal system. The firm’s partners served the Kingdom of Siam in many capacities, including as advisors to the Ministry of Justice and the Thai Royal Family.

Following World War II, Tilleke & Gibbins was acquired by American lawyers Albert and Freda Lyman. Along with their Thai partner, Roland (later Rojvit) Periera, the Lymans oversaw the growth of the firm’s international client base, while ensuring that the firm remained a pillar of Thai society by contributing to the founding of the American Association of Thailand (now the American Chamber of Commerce) and the Bangkok Stock Exchange (now the Stock Exchange of Thailand).

In the 1980s, David Lyman succeeded his father as the firm’s senior partner. During this period, the firm expanded internationally, with the opening of offices in Vietnam and membership in leading international law firm networks, beginning with Lex Mundi in 1989. In 2006, Tilleke & Gibbins appointed Darani Vachanavuttivong and Tiziana Sucharitkul as Managing Partners of the firm.

The history of Tilleke & Gibbins is one we share with our clients, our community, and the Kingdom of Thailand.

Wise Counsel:
A History of Thailand’s Oldest Law Firm

To celebrate the firm’s 120th anniversary in 2010, Tilleke & Gibbins released Wise Counsel, a 236-page illustrated chronicle of the firm. Published by Mark Standen and written by John Hoskin, Wise Counsel traces the firm’s development from William Alfred Goone Tilleke’s arrival in the Kingdom of Siam in 1890 through the various changes that have made the legal practice what it is today. The book features an impressive collection of historical photos, key partner profiles, and discussions of major cases, making it an excellent addition to any history enthusiast’s bookshelf.

When the young barrister William Alfred Goone Tilleke came to Siam in 1890, his future was delicately poised. Already highly accomplished, the 31-year-old Singhalese had left behind security and prestige enjoyed in his native Ceylon to seek his fortune in Siam, Southeast Asia’s last surviving independent state. Tilleke stepped ashore at Bangkok to enter into a life that held not just promise, but also the chance, if firmly grasped, to play a significant role in the development of modern Siam.

William Alfred Goone Tilleke made an international name for himself as defense counsel for the Siamese military commander Phra Yod Muang Khwang—whose prosecution for killing a French officer was demanded by the Franco-Siamese treaty. At the end of Tilleke’s brilliant cross-examination, the testimony of the principal prosecution witness, Bun Chan, sounded hopelessly unconvincing. All seven judges returned a verdict of Not Guilty.

Gibbins Joins the firm in 1902

The Tilleke & Gibbins partnership, joined by Ralph Gibbins in approximately 1902, was engaged in several famous cases, including a long trial concerning the settlement of the estate of the famous Admiral John Bush, the founder of the Bangkok Dock Company and former harbormaster.

Under the leadership of Samuel Brighouse and Reginald Atkinson, beginning in 1911, the law firm of Tilleke & Gibbins represented most of the leading firms in Bangkok, including The Bombay Burmah Trading Corporation Ltd., The East Asiatic Co. Ltd., The Anglo-Thai Corporation, and The Borneo Company Ltd

Tilleke & Gibbins was retained by the Privy Purse to assist in managing the private financial affairs of the King and the Royal Family. To conduct this business, Samuel Brighouse made a weekly visit to the Privy Purse and, with his car emblazoned with a large crest in the shape of a bull’s head that served as an entry pass to the royal offices, he became a familiar sight in Bangkok’s burgeoning traffic. The firm continued to represent the Privy Purse until 1932, the year of the bloodless coup that changed Siam’s political system from an absolute to a constitutional monarchy.

World War 1 1914

Samuel Brighouse and Reginald Atkinson, equally courageous and patriotic, both wished to fight for their country in World War I. As one of them would have to stay and take care of the business in Bangkok, family history has it that the two lawyers drew lots with Atkinson being the winner or loser, depending on your point of view. Atkinson joined the Welsh Cavalry as a lieutenant and served with distinction, finishing the war at the rank of major. Following the armistice of 1918, he lost no time in returning to Bangkok.

On March 7, 1917, a few days after suffering a heart attack, William Alfred Goone Tilleke died at his home at the age of 58. Tilleke served the Kingdom of Siam in many capacities including as a public prosecutor, Attorney General, and privy councilor. Tilleke also served on the drafting committees for Penal Law, the Constitution of the Courts of Justice and Civil Procedure, and the Civil and Commercial Code. Among the many titles and royal honors bestowed upon Tilleke, the title of Phra Attakarn Prasit continues to mark the lane where Tilleke lived, Soi Attakarn Prasit (Sathorn Soi 1).

Tilleke & Gibbins handled 37 court cases in 1937, the figure rising to 61 in 1940. The litigation was wide ranging, from the formation of companies to debt, bankruptcy, motor accidents, murder, attempted murder, and one case involving the Asiatic Petroleum Company, intriguingly referred to as “dangerous or noxious trades.”

Japanese forces land in Thailand 1941

On December 8, 1941, Japanese forces landed in Thailand. The Japanese took effective control of Bangkok and the Thai government remained in power in little more than name. Luckily, Reginald Atkinson, Victor Jaques, and their families had previously departed from Thailand. Samuel Brighouse was less fortunate; he, his wife, and all but their youngest daughter Jane (who was at school in Malaya and managed to escape to Australia) were caught in Bangkok and interned. For the first time since its establishment, Tilleke & Gibbins ceased operations.

Among the expatriates not interned was Ina Jorgensen, secretary to Victor Jaques, who retained her freedom as a national of Denmark, a country occupied by the Axis powers. Jorgensen was a resourceful and intrepid woman and was successful in not only keeping an eye on the Tilleke & Gibbins office, which had been occupied by the Japanese military, but also in preserving the documents of foreign companies and other clients held by the firm. Jaques would later assign the trademark side of the business to Jorgensen as a reward for her loyalty in safeguarding the firm’s interests during World War II.

In January 1945, Victor Jaques joined Force 136 of Britain’s Special Operations Executive (SOE) to execute an operation coded “Panicle.” The Allies believed that by connecting Pridi Phanomyong, a potential resistance leader in Thailand and the overall leader of the Free Thai Movement since 1943, with the Free Thai Movement overseas, they could undermine Japanese control in Thailand. Jaques was uniquely suited to infiltrate Thailand, make contact with Pridi, and act as a liaison between the Free Thai and Allied Command. Jaques successfully completed this mission, was promoted from acting to full brigadier, and was briefly the temporary British military governor of Thailand.

Tilleke & Gibbins was back in business, its usual caseload augmented by war claims against the Thai government on behalf of individuals and European companies. Victor Jaques, the sole remaining partner after the war, brought into the firm a young trial lawyer named Roland (later Rojvit) Periera.

In the 1950s and 1960s, much of Albert Lyman’s attention was taken up with legislation and activities concerning trademarks and their infringement. This was a business he had to build up from scratch, as all such intellectual property work previously handled by the firm was transferred to Jorgensen after World War II. Borrowing the idea from a similar procedure used by Western colonial powers in China, Albert developed consular registration for patents, which went some way to providing protection for patent holders. The groundwork laid by Lyman in these areas bore abundant fruit in later years when Tilleke & Gibbins became one of the foremost legal experts on intellectual property.

In July 1951, Albert Lyman bought Tilleke and Gibbins from Victor Jacques for the price of USD 2,500 which he had borrowed from his wife, Freda Lyman. Under the leadership of the Lymans, the firm added more recently arrived and mainly (though not exclusively) American companies, including Caltex, Getz Bros & Co., Pepsi-Cola, Chase Manhattan, and Bank of America to its roster of clients, which continue to include established British trading concerns such as The Borneo Company Ltd. and foreign banks like the Hong Kong and Shanghai and the Mercantile Bank.

In 1950, Albert Lyman was a founding member of the American Association of Thailand which, in 1957, evolved into the American Chamber of Commerce, with Albert as one of its co-founders and its legal adviser for many years. Albert was also the inspiration for the founding of the Bangkok Stock Exchange (now the Securities Exchange of Thailand) in 1961 and served as its chairman for 10 years.

Through her work with the American Women’s Club, Freda Lyman became actively involved with charitable activities aimed at aiding crippled children. She played a large part in the creation of the Foundation for Crippled Children, which in turn led to other welfare projects such as the Cheshire Homes. In recognition of this work, Freda was awarded the Most Noble Order of the Crown of Thailand 5th Class in 1961, making her the first foreign woman to be decorated by His Majesty King Bhumibol Adulyadej.

In 1967, David Lyman, the son of Albert and Freda, joined Tilleke & Gibbins and began developing new clients and new systems for the firm. By the mid-1970s, business was expanding noticeably, especially in the fields of intellectual property and commercial and corporate business. Increasingly, large international contracts were secured and, for example, Tilleke & Gibbins handled the formation of Diners Club and American Express in Thailand, marking the first major entry of credit card companies into the country.

Largest case in Thai history 1970s

In his long career with the firm, Roland (later Rojvit) Periera appeared in more than 1,000 cases, many of them ranking among Bangkok’s most notable post-World War II trials. One of these cases was, at the time, the largest in Thai history in 1971, involving suit worth THB 400 million between Siam Kraft Paper and Parsons & Whitmore, a construction company, concerning the Siam Kraft factory in Kanchanaburi. He succeeded in securing a satisfactory outcome to the litigation for Parsons & Whitmore. Periera was also the lead attorney for Air India in a successful case involving the Customs Department (1976) and secured a victory for the Bank of America in a case involving deferred taxes (1970). Periera would later be joined at the firm by his sons Thanes and Santhapat Periera.

On April 10, 1984, Albert Lyman succumbed to diabetes. He was followed by his wife, Freda Lyman, who passed away on July 18, 1986. Anecdotes abound attesting to the high regard in which Albert Lyman was held by all who knew him. As part of the after-dinner entertainment at a party hosted by the British Ambassador, eight British and two American guests were posed the hypothetical question of whom they would contact if they suddenly found themselves in a dangerous or threatening situation in Thailand and could make only one telephone call. Not one of the guests gave the obvious answer (of getting in touch with their embassy), but six of them did agree—they would call Albert Lyman.

In 1989, Lex Mundi contacted David Lyman, which resulted in Tilleke & Gibbins joining what is the world’s premier international grouping of independent law firms. This membership grew to give the firm access to the expertise and experience of more than 21,000 attorneys in over 160 jurisdictions, thus vastly enhancing its services in handling cross-border transactions. In becoming a member of Lex Mundi (and subsequently several other international legal networks), Tilleke & Gibbins anticipated the trend towards globalization that continued through the last decade of the twentieth century and into the new millennium.

Expanding to Vietnam 1992

In July 1992, Tilleke & Gibbins became the first foreign law firm to be granted a licensed to establish a representative office in Vietnam. The new office, located in Ho Chi Minh City, the commercial heart of the unified Vietnam, was followed by the establishment in January 1994 of a branch office in Hanoi, the nations capital. Both offices were awarded full branch office licenses in 1996.

In 1993, Tilleke & Gibbins launched the Second Hundred Years Forest Project, a community project in recognition of the firm’s second century of client service. Working with the Rajapruek Foundation, the Royal Thai Army, the Royal Forestry Department, and friends of the firm, including long-time client, the Thoresen Group, the firm planted over 100,000 trees in five phases between 1993 and 2010. The Second Hundred Years Forest Project is currently in its sixth phase.

On August 4, 2006, Tilleke & Gibbins appointed Darani Vachanavuttivong and Tiziana Sucharitkul as Co-Managing Partners of the firm. Darani Vachanavuttivong heads the firm’s intellectual property group and is a formidable enforcer of intellectual property rights, including trademarks, copyrights, and patents. Darani is currently recognized as a top IP practitioner by such publications as 

On August 1, 2008, Tilleke & Gibbins and Pacific Legal Group (Thailand) Ltd. merged their practices. This combination allowed the firm to offer clients Thai Food and Drug Administration (FDA) and Ministry of Agriculture (MOA) registration and regulatory compliance services of the highest quality rendered by the largest and most experienced group of Thai FDA and MOA registration and regulatory compliance specialists.

A new mediation law for smarter dispute resolution of civil and commercial disputes – II

Published

on

(Part I of this article appeared in The Island yesterday.)

An examination of how some of the other countries have institutionalised mediation to address the problem of laws delays shows that an array of institutional devices have been adopted to provide for mediation not only as a voluntary option but also in some jurisdictions, as a mandatory requirement prior to litigation, to respond to serious issues of delays due to congestion in courts.

In the UK , in March 1994, the Lord Chancellor commissioned Lord  Woolf to review the Rules of civil procedure with a view to improving access to Justice, reducing the cost of litigation and removing unnecessary complexity. The resulting  Access to Justice Report (1996) triggered a series of reforms to improve the civil justice system primarily through the civil procedure rules (1999) which articulated that its overriding objective is to enable the court to deal with cases justly and at proportionate cost. In 2023, the Court of Appeal judgment in Churchill v. Merthyr Tydfil County Borough Council [2023] EWCA Civ  1416, decided that English courts do have the power to stay civil proceedings for, or order, parties to engage in mediation or another non-court- based dispute resolution process. The Rules were thereafter amended in 2024 to provide for the use of alternative dispute resolution (ADR) more proactively. These included rules that recognied that –

* promoting  or using ADR is a means of achieving the overriding objective;

*  the court has a duty to actively manage cases to further the overriding objective, including by ‘ordering or encouraging the parties to use, and facilitating the use of, alternative dispute resolution’ and ‘helping the parties to settle the whole or part of the case’

* in deciding a costs order, a court will have regard to all the circumstances of the case, including the conduct of the parties, including whether a party failed to comply with an order for ADR or unreasonably failed to engage in ADR.

An ADR pledge made by the UK Government in 2001 was renewed in 2011, by the Dispute Resolution Commitment (DRC) requiring departments to use mediation, arbitration and conciliation. At that time, the then Justice Minister Jonathan Djanogly said: ‘I believe that government should be leading by example by resolving issues away from court using alternatives which are usually quicker, cheaper and provide better outcomes. We want people to see court as a last resort rather than a first option, and cut down on the amount of unnecessary, expensive, painful and confrontational litigation in our society. In many cases methods like mediation are simply a common sense solution which benefits everyone involved. Although they will not be suitable in every case, they are already saving taxpayers millions every year and can save much more.’

The judicial dicta on the power of the courts to order mediation and the imposition of costs on even a successful party for unreasonable refusal to mediate, provides clear acceptance of a pro mediation approach by the UK courts.

In the USA , the discussion on the need for alternatives was raised in a speech made in 1906, by Roscoe Pound, a relatively unknown legal academic at the time, addressing the annual meeting of the American Bar Association (ABA). The title of his address was “The Causes of Popular Dissatisfaction with the Administration of Justice.”  He critiqued the American legal system and charged that it was riddled with archaic technicalities, too slow, too expensive and adversarial and that there was injustice when  procedure received emphasis above the substantive issues of a conflict. He spoke of the “sporting theory of justice” where litigation was considered as a game where the lawyers were gladiators battling in court to win. He charged that the contentious procedure compels ‘counsel to forget that they are officers of the court and  to deal with the rules of law and procedure exactly as the professional football coach with the rules of the court.’ At the time, Pound’s criticisms were considered scandalous, blasphemous and the ABA refused to publish the speech.  Things changed however.

Thirty years later, Roscoe Pound went on to become Dean of the Harvard Law School and became  a celebrated legal luminary. As for the legal system – Roscoe Pounds sentiments were not dismissed. Seventy years later in 1976, the then Chief Justice Warren Burger convened the Pound Conference (called the second  Pound Conference, with the first attributed to Pounds’ 1906 speech event), to consider whether Pounds’ criticisms had been adequately addressed and what more needed to be done. Professor Frank Sander of the Harvard Law School delivered the keynote address and spoke of his vision for a comprehensive Justice center (the “multi door court house”) where an alternative system would function parallel to the litigation system and disputes would be directed to the most appropriate process, such as arbitration and mediation.

The impact of these discussions resulted in significant changes to the dispute resolution landscape in the USA through statutes, inclusion of ADR in academic courses, and the professionalization of the practice of ADR processes, including mediation. Currently, arbitration and mediation are recognized within the mainstream legal system with resounding success.  All the States have recognized ADR pathways including mediation, in statutes. Mediation is well entrenched in the USA and the success rate is reportedly very high.

Australia has institutionalized mediation through several statutory and other initiatives. Courts are empowered to refer disputes to mediation without the consent of the parties to enable better management of civil matters. The Civil Dispute Resolution Act,  2011 contains provisions to ensure that, other than in respect of certain excluded civil proceedings,  parties must take “genuine steps” to resolve disputes prior to litigation. The Act obligates parties instituting proceedings in court to file a “genuine steps statement” setting out the steps taken to resolve issues or the reasons why no such steps were taken and further provides that a Lawyer acting for such a party must advise that party of the requirement and assist that party to comply with that requirement.

In Ireland, in the very recent case of Burke v O’Connell  [2026] IEHC 314 (May 20, 2026), the High Court considered  whether a court can order parties to mediate a dispute, against their will, or whether a court is restricted to simply inviting the parties to mediate. Among other issues, the court considered whether mandatory court ordered mediation is a breach of a constitutional right of access to courts, and decided that a court delaying court proceedings for court ordered Mediation, even against the will of the parties, would not constitute a breach of the right access to the courts under the Constitution or the European Convention on Human Rights, and that judges in Ireland regularly make clear that the right of access to the courts is not unconditional. Importantly the court observed that the court is not directing the parties to reach an agreement but simply to commence  a mediation.  The Court also observed that a court directed mediation order is a very limited order which does not compel settlement and only requires parties to commence a Mediation process and that while attendance at Mediation may not be voluntary, reaching a settlement is voluntary and made order that a court, in controlling its own process, did have the power to direct Mediation in appropriate cases, and that it was an inherent power of the court to ensure the effective and efficient operation of the courts.

 The Indian Mediation Act, 2023  articulates a pro mediation policy and provides for mediation via a court annexed scheme for which detailed statutory provisions are included. The Act states that parties may voluntarily, and whether there is a mediation agreement or not, take steps to pursue court annexed pre litigation mediation and provides for the steps to be taken therefor (section 5). The Act provides further that, even if such pre litigation mediation is unsuccessful, a court or tribunal may, at any stage of the proceedings, refer parties to undertake mediation and that when a court so refers a dispute, there is no obligation on the parties to come to a settlement (section 7). In respect of high value commercial disputes however,  a plaintiff is required to exhaust ‘the remedy of  pre institution mediation’ prior to instituting action, unless urgent interim relief is sought – section 12A introduced by the Commercial Courts, Commercial Division, and Commercial Appellate Division of High Courts (Amendment) Act, No. 28 of 2018.

 In South Africa, parties are mandated to consider mediation before initiating  litigation in the High Court. Challenged by a serious issue of a severe backlog, with trial dates scheduled even up to 2031, a Directive was issued by the Judge President of the Gauteng Division of the High Court along with a detailed process Protocol, effective April 2025 to require mandatorily that prospective litigants in all civil matters within the Gauteng division must participate meaningfully in a court-annexed mediation process before they can be allocated a trial date. The protocol requires, among other documents, that a Report of the Mediator stating, among other matters, whether parties “participated in good faith” be filed, to obtain a trial date. This requirement has been included to avoid what the Judge President refers to as “sham mediations.”  (https://www.youtube.com/watch?v=v5Gmkzfu8gA&t=425s) Non-compliance results in matters being struck off the roll and could lead to adverse or punitive cost orders. Currently, a challenge to this Directive by the Personal Injury Plaintiff Lawyers Association and the Law Society of South Africa is pending, without a stay of the Rule.

 Singapore has emerged as a global leader in the practice of mediation. The Mediation Act 2017 provides for a framework for the use of mediation and for enforcement of a mediated settlement agreement as a decree  of court. Mediation is well entrenched in the legal system of Singapore and enjoys the support of government as well as the judiciary. Singapore played a key role in UNCITRAL in the deliberations that led to the drafting of the text for the 1998 UN  Mediation Convention and was host to the Convention signing ceremony in August 1999 where a historical number of 46 countries, including Sri Lanka, signed the Convention on the very first day. Many of the training programmes for Sri Lankans that have been arranged by the International ADR Center, have been conducted by the Singapore International Mediation Centre (SIMC) which is renowned for its programmes and for services to handle international commercial disputes.

 The European Union Directive (EU Directive 2008/52/EC) provides that a court may, when appropriate and having regard to all the circumstances of the case, invite parties to use mediation (Article 5.1) and that the Directive is without prejudice to national legislation to making the use of mediation compulsory or subjective to incentives or sanctions … provided that such legislation does not prevent the parties from exercising their right of access to the judicial system (Article 5.2). Many European countries have integrated mediation into their dispute resolution systems through legislation or procedural laws in ways that range from recognizing voluntary reference to mediation to requiring mandatory mediation for specified categories of disputes. Countries such as Italy, Greece, Germany and Belgium are some that have robust systems.

It is clear therefore, that jurisdictions around the world, irrespective of the legal system, have sought to recognize mediation for its value not only for minor community dispute resolution but also for the resolution of high value commercial and other family and civil dispute resolution.  UNCITRALs preparation of the text for the 1988 UN Mediation Convention was inspired by the significant increase in the use of mediation in international trade and the need for a uniform regime for enforcement, such as the UN NY Arbitration Convention provides in respect of arbitration awards.

 Sri Lanka’s advancements have thus far been driven by the private sector. A holistic approach to find responses to the backlog in courts to relieve the pressure on courts, is desired. The promotion  of ADR, including mediation, deserves support from the government as well, since, clearly, laws delays have an adverse impact on the economy of the country and should not be seen only as an access to justice issue. As articulated in the UN Mediation Convention, among the positive beneficial results of using mediation for dispute resolution, is that there are cost savings for the State. It is a means of resolving disputes without detracting from the quality of the resolution.

Killing of Colombo’s ancient trees — a warning on UN’s World Desertification Day – 17 June

Published

on

A fallen tree in Colombo. (File photo courtesy NewsFirst)

In recent years, falling trees have claimed lives, destroyed homes, and sparked an urgent debate: should Colombo’s ancient trees be cut down in the name of safety? But this is the wrong question. The real crisis is not that these trees are dangerous — it is that we have made them so. Through decades of road widening, root-smothering pavements, and indiscriminate branch cutting, we have steadily undermined the very trees we now fear. What we are witnessing is not nature failing us. It is us failing nature. As the world marks World Desertification Day on 17th June, Sri Lanka would do well to reflect that desertification does not begin only in distant, arid lands — it begins whenever a city turns its back on its own green heritage.

In recent years, falling trees have claimed lives, destroyed homes, and sparked an urgent debate: should Colombo’s ancient trees be cut down in the name of safety? But this is the wrong question. The real crisis is not that these trees are dangerous — it is that we have made them so. Through decades of road widening, root-smothering pavements, and indiscriminate branch cutting, we have steadily undermined the very trees we now fear. What we are witnessing is not nature failing us. It is us failing nature.

Colombo, our commercial capital, is considered one of the greenest cities in the world. This is highlighted by the award of the world’s first Wetland City designation to our administrative capital, Sri Jayewardenepura Kotte. Both cities and their green heritage should be treasured and protected — not only as assets of their citizens, but as a matter of national pride.

It is against this backdrop that one must view with deep concern the ongoing destruction of trees and greenery across Sri Lanka, particularly in urban settings such as Colombo and Kotte. The majestic trees lining our traditional tanks, rural areas, and urban areas are part of our heritage. The trees lining Colombo’s Ananda Coomaraswamy Mawatha (previously named the Green Path because of its large trees), Gregory’s Road, Thurstan Road, and Bauddhaloka Mawatha, are over a hundred years old. These are living monuments of our heritage. They provide shade, a natural canopy, and a habitat for a remarkable diversity of bird populations within the city. It is therefore vital that we make every effort to preserve these trees unless they pose a direct danger to human life.

Why Do These Trees Become Dangerous?

To address this question, we must first understand why large trees continue to fall during periods of strong winds. Old photographs indicate that it is we who have widened roads and built pavements to cover the roots of these majestic trees, a true heritage from the past.

A leading reason for trees to fall is age-related decay. Old trees tend to develop weak branches and trunks. Regular inspection of their structural integrity and timely treatment of disease would go a long way in preventing such failures.

The second reason is indiscriminate cutting of branches, which disrupts the natural balance of the tree. A principal offender in this regard is the Ceylon Electricity Board. When interviewing workers engaged in trimming city trees, one consistently hears the same justification: the branch must be cut because it is touching or close to a power line. There are no arborists, trained experts, or senior officials to guide these workers or determine whether a less destructive approach is possible.

The third reason is the destruction of root systems. Across the city, one can observe concrete and paving laid directly over the root zones of large trees. This prevents oxygenation and moisture from reaching the roots, causing them to deteriorate or die. The inevitable consequence is that the tree gradually loses its structural support at the base, making it vulnerable to falling.

What Should Municipalities and Town Councils Do?

To save our ancient trees, we must counter the flawed argument that we need to replace them—these trees are priceless “nature’s investments for hundreds of years” and, as a BBC article on ancient oaks suggests, their genetic heritage is vital for resilient future forests. See “1,000-year-old oaks used to create ‘super forest’ (See )

*  A nationwide strategy is essential: we must start by strengthening the expertise of tree officers in the Colombo Municipal Council and other urban councils to ensure professional health assessments are available, while also linking with botanists, academics, and environmental groups at the University of Colombo.

*  Use Google Maps and GIS for systematic mapping and reviving a citizen science platform, similar to one previously developed by University of Moratuwa, where students and the public can report environmental harm with photos and locations.

*  Technology offers more powerful tools. There are Conventional Visual Tree Risk Assessment (VTRA) methods which fail to detect risks. More advanced methods were reported at the 30 th International Forestry and Environment Symposium 2026 e.g. Ground Penetrating Radar (GPR). These are able to find trunk decay and found examples in urban trees at Viharamahadevi park and Keppetipola road.

*  We can raise public awareness through social media and community events like “tree walks,” a practice which could be further popularized by groups like Ruk Rakaganno (see ) and the Love A Tree Foundation (see )

*  Finally, we must learn from international models like the UK’s Ancient Tree Forum (see ). The latter specialises in protecting trees as a heritage which must be preserved and protected for future generations.

Dengue and its prevention: A global public health challenge

Published

on

Dengue is one of the fastest spreading mosquito-borne viral diseases in the world today, posing a growing threat to nearly half of the global population. The World Health Organization describes dengue as a viral infection transmitted to humans through the bite of infected female mosquitoes, primarily Aedes aegypti and, to a lesser extent, Aedes albopictus. Once considered a disease limited to tropical regions, dengue has now expanded widely across continents, driven by urbanization, climate change, population movement, and weak vector control systems.

The global burden of dengue has increased dramatically over recent decades. According to WHO estimates, there are approximately 100 to 400 million infections annually, although a large proportion remain asymptomatic or undiagnosed. The disease is now endemic in over 100 countries, with Asia bearing the highest share of cases, followed by Latin America and Africa. As transmission intensifies and outbreaks become more frequent, dengue has emerged as a major public health concern requiring coordinated prevention and control strategies.

The nature of dengue infection

Dengue is caused by four closely related viruses known as serotypes: DENV-1, DENV-2, DENV-3, and DENV-4. Infection with one serotype provides lifelong immunity to that specific strain, but only partial and temporary protection against the others. This means a person can be infected up to four times in their lifetime.

Most dengue infections are asymptomatic or mild. When symptoms do occur, they typically appear 4 to 10 days after the bite of an infected mosquito. The clinical presentation includes high fever, severe headache, pain behind the eyes, muscle and joint pain, nausea, vomiting, rash, and fatigue. Because these symptoms resemble other viral infections, dengue is often underdiagnosed in early stages.

While most patients recover within one to two weeks, a small proportion develop severe dengue. This life-threatening condition is characterised by plasma leakage, severe bleeding, organ impairment, and shock. Without timely medical intervention, severe dengue can be fatal. WHO emphasises that early diagnosis and appropriate clinical management can reduce fatality rates to below 1 percent in well-managed settings.

Transmission and mosquito ecology

Dengue is transmitted primarily through the bite of infected female Aedes mosquitoes. These mosquitoes are highly adapted to urban environments and typically breed in artificial water containers found in and around homes. Unlike malaria-transmitting mosquitoes, Aedes mosquitoes bite during the daytime, with peak activity in the early morning and late afternoon.

The lifecycle of the mosquito plays a crucial role in transmission. Eggs can survive for months in dry conditions and hatch when they come into contact with water. Even small collections of water, such as flower pots, discarded containers, tyres, and water storage tanks, can serve as breeding sites.

Urbanisation has significantly contributed to the spread of dengue. Rapid population growth in cities often leads to overcrowding, poor waste management, and inadequate water storage practices, all of which create ideal breeding conditions for mosquitoes. Climate factors such as increased rainfall, humidity, and temperature further enhance mosquito survival and virus replication.

Risk factors and global expansion

Several factors increase the risk of dengue transmission. Population density is a key driver, as densely populated urban areas provide abundant human hosts for mosquitoes. Inadequate housing conditions and poor access to clean water force communities to store water in containers, which often become breeding grounds.

Human mobility also contributes to the spread of the disease, as infected individuals can introduce the virus into new regions where competent mosquito vectors are present. Climate change has expanded the geographical range of Aedes mosquitoes into previously unaffected areas, increasing the risk of outbreaks in both tropical and subtropical regions.

WHO has noted that dengue incidence has increased significantly over the past 50 years, with periodic outbreaks becoming more frequent and severe. The disease is now considered a major global health threat, comparable in burden to other high-impact infectious diseases in many regions.

Clinical management and absence of specific treatment

There is currently no specific antiviral treatment for dengue. Management is supportive and focuses on relieving symptoms and preventing complications. Paracetamol is recommended to reduce fever and pain, while non-steroidal anti-inflammatory drugs such as ibuprofen and aspirin are avoided due to their risk of increasing bleeding.

Patients with severe dengue require hospitalisation for close monitoring and supportive care, including intravenous fluid replacement and management of shock or bleeding. With proper medical care, mortality rates can be significantly reduced.

Early detection is critical. Warning signs such as persistent vomiting, severe abdominal pain, bleeding gums, rapid breathing, and sudden fatigue indicate progression to severe dengue and require immediate medical attention.

Prevention: the cornerstone of dengue control

Since there is no specific cure, prevention remains the most effective strategy against dengue. WHO strongly emphasises integrated vector management as the foundation of dengue control.

Personal protection measures are essential, especially during daytime hours when mosquitoes are most active. These include the use of mosquito repellents containing DEET, picaridin, or IR3535, wearing long-sleeved clothing, and using mosquito nets when resting during the day. Window and door screens also help reduce indoor mosquito exposure.

Environmental management is equally important. Communities are encouraged to eliminate breeding sites by removing stagnant water, disposing of waste properly, and cleaning water storage containers regularly. Even small water collections can sustain mosquito populations, making household-level participation crucial.

Public health programmes also rely on insecticide spraying during outbreaks to rapidly reduce mosquito populations. However, WHO emphasises that chemical control alone is insufficient without sustained community involvement and environmental management.

Community participation and public health response

Community engagement is a central pillar of dengue prevention. Effective control requires continuous participation from households, schools, workplaces, and local authorities. Public awareness campaigns play a vital role in educating populations about mosquito breeding habits and personal protection measures.

Surveillance systems are also essential for early outbreak detection and response. Health authorities monitor dengue cases and mosquito populations to identify high-risk areas and implement targeted interventions.

Integrated approaches that combine environmental management, biological control, chemical interventions, and public education have proven most effective in reducing transmission.

Vaccination and emerging tools

In recent years, dengue vaccines have been developed and introduced in some countries under specific conditions. WHO has recommended the use of certain vaccines in areas with high transmission, particularly for populations with prior exposure to dengue. However, vaccination strategies remain limited and must be carefully implemented due to the complexity of immune responses to dengue infection.

Research continues into new tools such as genetically modified mosquitoes, Wolbachia-infected mosquitoes that reduce virus transmission, and improved diagnostic technologies. These innovations offer promising additional tools but are not yet substitutes for established prevention measures.

Dengue remains a rapidly growing global health challenge with significant medical, social, and economic impacts. Its spread is driven by urbanisation, climate change, and the adaptability of mosquito vectors. While no specific cure exists, timely clinical care can prevent deaths, and effective prevention strategies can significantly reduce transmission.

The World Health Organization emphasises that dengue control depends on a combination of personal protection, environmental management, community participation, and strong public health systems. As the disease continues to expand geographically, sustained global commitment is essential to reduce its burden and protect vulnerable populations.
