Managing Food crop pests without compromising yield and environment

Published

on

By DR. Chandrasiri Kudagamage

Insect pests cause substantial damage to our food crops. Insecticides are normally applied to combat them. However, dependency solely on insecticide for pest management has resulted in various undesirable environmental and human health problems. Human health is affected by the consumption of food with insecticidal residues. Also, the destruction of friendly insects such as pollinators, predators and parasites, is among some of environmental effects of indiscriminate use of insecticides. Long-term persistence of some chemicals in the environment and frequent exposure to these chemicals may also result in different forms of cancers. Sri Lanka ranks very high as regards pesticide-related health hazards and around 20,000 poisoning cases are reported per year and of them 1,600 are fatal. Seventy percent of them were related to suicide. (Registrar of Pesticide)

With the development of herbicide resistant crops like soya bean, corn and wheat the use of total weed killer glyphosate has increased and become most widely used herbicides in history. Farmers, in 2014, sprayed enough of the chemical to cover every acre of cropland in the entire world with nearly a half- pound of the herbicide, according to a 2016 study published in Environmental Sciences Europe. With this intensity of use glyphosate is likely to cause problems and as a result, this herbicide is being increasingly scrutinised for human health impacts. Scientists say it also could be altering the wildlife and organisms at the base of the food chain.

DDT was a widely used insecticide during post world war times. The popularity of this insecticide was due to it less acute toxicity. However, it was subsequently known that this insecticide accumulated in the fat layer of fish and mammals. It was banned in 1970s in our country. However, the use of insecticides continued and many farmers believed chemicals are important input for reducing yield losses.

Undesirable effects of chemicals came to be realised worldwide shortly after the wide use of agro-chemicals in post-world war times. Famous environmentalist and a marine biologist by profession, Rachel Carson in her book, ‘Silent Spring 1962’ highlighted the bad effects of indiscriminate use of chemicals. This inspired grass root environmental movements and others to highlight these effects in various forums. Carson did not anticipate a total ban on pesticide. However, she predicted consequences of over use of chemicals on biodiversity and target pests developing pesticide resistance etc. This led to establishment of environmental protection agency(1970) by an executive order from US President Richard Nixon. The purpose of this agency was to protect human health and environment. Similar legislature also being adopted in our country. The pesticide law 33 of 1980 was enacted to regulate import, manufacture, distribution and use of agro-chemicals in Sri Lanka.

 

Alternative Approach

 

To address the above issues new concept of pest management popularly known as Integrated Pest Management or IPM was launched and it evolved into an Eco-friendly and economical pest management tool. This approach has been recognised as a policy for the management of pests by successive governments. However, enough funding in the form of manpower, funding for conducting research, laboratory and analytical facilities has been limiting. This has slowed the progress of IPM in pest management in several crops.

The primary objective of IPM is to develop an economical eco-friendly pest management package where pesticides are used as the last resort when other control measures fail and the pest population exceed a certain threshold called the economic threshold. IPM integrate well with other available control methods and can be applied to any ecosystem such as crop based, home garden, greenhouses and domestic pest control.

Following globalisation and transboundary movements of food and with the increase of demand for diverse food, there has been a concern for contamination of food with various pathogens and chemical residues. Hence agriculture practices need to be introduced to minimise these effects. Recently-introduced Good Agriculture Practices (GAP) fulfil this requirement and goes beyond the scope of IPM.

IPM has various components such as mechanical control (use of bags for fruit fly control), use of resistant varieties, biocontrol (use of predators, parasites and microorganism) and legislative and quarantine (banning of imports from infested country).

 

IPM experience with major food crops

 

There are about five or six major insect pests in our staple crop rice. These pests infest different stages of the crop. Among the pests, rice brown planthopper (BPH) and rice gall-midge play an important role causing low to high of damage depending on the prevailing climate. Due to the cultivation of resistant varieties the incidence of rice gall-midge was very low compared to the times when susceptible varieties were cultivated. With respect to rice brown planhopper , the first resistant variety was introduced to farmers in 1980s. Although resistant varieties are ideal as an insect management method, evolution of new strains that can attack these resistant varieties remain a problem. This has happened with respect to gall-midge resistance where resistance broke down in rice varieties cultivated in the 1980s. However, rice breeders and entomologists were able to introduce a new resistant variety by 1984. There are reports of breaking down of this resistance in the recent times. This indicates importance of constant attention in monitoring resistance, management of resistance and finding new sources of resistance. The availability of molecular genetic tools make it easy for the incorporation novel forms of resistance, which is more stable.

The pests that attack at the seedling stages such as thrips are best approached by following correct planting time as heavy infestation is observed in late planted crop. With respect to rice bug which infest crop after flowering, use similar planting time in a Yaya, weeding around the bunds before weeds flower are important non-chemical methods

Although IPM in rice is fairly successful, it is not widely applied in vegetables and other crops. A study conducted by the Department of Agriculture (DOA) in four major vegetable growing Districts in Sri Lanka showed that 85% of farmers in the Badulla District applied pesticides to their crops before the appearance of any pests or symptoms. In the Nuwara-Eliya District this was recorded at 66%. This shows that chemical controls are used even before pest damage has exceeded economic threshold levels and the use of pesticides as a precautionary measure has become common.

Cucurbit fruitfly and melon fly infestation is the most common limiting factor in the cultivation of cucurbit crops for local consumption and export. The melon fly lays eggs deep inside the fruit. The emerging larvae feed inside the soft tissue. This results in fruit dropping and decay. The larvae pupate in soil. Insecticide control is difficult since larvae feed inside the fruit and avoid direct contact with insecticide. In the export consignment, if a single larva is present the whole consignment can get rejected. Therefore, alternative control strategy based on IPM concepts are required. There are several strategies such as bagging of fruits, collection of crop residues and decaying and fallen fruits into a black polythene bag which help to destroy the larvae due to heat developed inside the bag. Together with these cultural methods, application of protein bait is an innovative approach to control this pest. The female flies are attracted to protein substance and consumption of protein help to mature their eggs. Proteinous material prepared from locally available substances are mixed with soft insecticide and applied to leaves instead of fruits. To reduce the amount of insecticide used application to few spots of the crop is sufficient to reduce the female melon fly population. For more effective results these IPM methods need to be applied on wide area basis such as Yaya or cropping area.

Mealy bug was reported to infest papaya fruits in different parts of the country in the late 1980s. This insect is a invasive pest rapidly infesting many species crops. However, main host is papaya. Due to its rapid multiplication rate and wide host range insecticide control is not successful. In other countries where this insect was found, the population of mealy bug is kept at lower level because of the action of the predators and parasite. DOA has already released a effective parasite obtained from United State Department of Agriculture’s Animal and Plant Health Inspection Service parasite rearing facility, in areas where this pest was found.

In Dec. 2018, another pest Fall Army Worm was observed infesting maize in all major maize growing areas. It was also found to infest sugar cane. This pest is native to America. Outside its native habitat it was first found in Central and Western Africa in 2016, and then quickly spread to sub Saharan Africa and in 2018 it was reported from many Indian states. It is a good example of trans boundary movement as the adult moth is capable of flying hundred of kilometres per night. Also, in the absence of native parasites and predators, other control methods based on IPM concepts need to be developed. Initially, experience of small farmers of South America, where the pest is endemic will be valuable tool for the development of control methods. However, research and farmer awareness programme is of paramount importance to develop more realistic management programme for this new pest.

Taking IPM into farmers’ fields

Many believe the concepts developed in IPM is too complex for the average farmer to understand because it involves counting, record keeping and various calculation for economic threshold determination. Hence, farmers need to be introduced to simpler approach to study the crop growth, pest infestation and natural enemy abundance. This is achieved by a group-based learning process. This is known as the Farmers’ Field School. According to this method around 20- 25 rice farmer groups collectively, study the progress of their crop from establishment to harvesting. For this farmers meet together once a week and observe their fields and share their experience with respect to growth of the crops and those factors that limit the growth including the action of pests, and abundance of natural enemies, etc. Depending on the outcome of the observation of their fields, decision will be taken to take action if the pest population grows up. This is a learner centred process where the agriculture instructor is only a facilitator. The impact of this programme was felt by the increases in yield, reduced insecticide use and favourable bio-diversity factors like abundance of predators and parasites.

Apart from government extension, NGOs such as Sarvodaya, CARE and Sri Lanka Red Cross have provided their support on IPM by conducting training programmes on IPM, but, focusing mainly on paddy.

 

Pesticide Management

A comprehensive pesticide control procedure in the form of pesticide law 33 of 1981 is in existence in the country, but enforcement is low due to several reasons. Often advice regarding pesticide selection was given by the pesticide seller in the village. As a result farmers may select the wrong pesticide, Over use of pesticide is common. They do not use correct dose and dilution. Often they apply pesticide even before appearance of the pest. Also, they do not follow correct post harvest interval. Although, provisions are available to mitigate these shortcomings via the pesticide law, the best way to tackle is through farmer training based on a good extension program.

Under the pesticide law, every product imported to the country has to be registered. Further field monitoring and enforcement of correct use, laboratory testing for quality and residues, imports regulations in the form of banning and restricting the pesticide are carried out. Over the years, the use of WHO Class1 pesticides has been prohibited and these products banned.

Instead of conventional pesticide, there are several specific pesticide registered in the country having low toxicity to humans. Some of these products affect insect hormone system and hence specific to them. Also, available in the market are several neem based botanical pesticide which are effective particularly on caterpillar pests. Additionally, there are bacterial insecticides which result in gastric problems in insects. Insect become sick and die when they consume leaves treated with these insecticide. These insecticides act on few species of insects and easily break down when exposed to light and other environmental factors. Hence, these products are not very popular with farmers although they are safe and environmentally friendly. For these specific pesticides, there are opportunities for use in home gardens and in greenhouses

 

Future development and promotion of IPM

There are several shortcomings in the development and implementation of IPM. There is a dearth of trained extension workers to deal with large number of farmers involved in crop production. To address this issue, leader farmers can be trained in IPM methods and they can be used to train other farmers in a Yaya or in a village. The government extension workers can be facilitators in this training programme as explained above with respect to Farmers’ Field School method of training. However, more intensive training programme for extension workers covering many aspects of IPM and successful experience of IPM particularly from rice IPM programme needs to be integrated into their training curriculum. Farmer field school programme has been adopted in many countries the world over and the knowledge is shared in the form of reports, videos, manuals, field guides and podcasts. Hence there is lot of avenues to incorporate relevant information in the training curriculum of the extension workers in our country.

Consumer awareness of environmental and health hazards of pesticides and particularly of the persistence in the environment needs to be created to reject food contaminated with pesticides. For this facilities for pesticide residue analysis needs to be improved.

Field demonstration of IPM methods with the involvement of researchers, extension workers and farmers needs to be established. By following IPM methods used in these demonstration, farmers can pick up the most appropriate IPM methods to test in their fields. More investment is needed to promote innovative research such as melon fly control as explained above. Participatory IPM trials and development of simplified IPM packages for major pests and diseases are also necessary for popularising IPM among farmers.

Globalisation of trade and travel, and introduction of improved planting materials can cause accidental introduction of pests. Papaya mealy bug and fall army worm are recent examples of such pest introduction. Facilities available at the plant quarantine station need to be improved for identification of pests of quarantine significance.

There is also an increasing interest in utilising information technology in agriculture to help extension advisers and other intermediaries in delivering up to date information to farmers to manage their crops. Development Mobile Apps that work offline for early warning and surveillance of pests helps farmers make quick decisions for the management of pests.

Trade preferences to support post-Ditwah reconstruction

Published

on

Ditwah disaster

The manner in which the government succeeded in mobilising support from the international community, immediately after the devastating impact of Cyclone Ditwah, may have surprised many people of this country, particularly because our Opposition politicians were ridiculing our “inexperienced” government, in the recent past, for its inability to deal with the international community effectively. However, by now it is evident that the government, with the assistance of the international community and local nongovernmental actors, like major media organisations, has successfully managed the recovery efforts. So, let me begin by thanking them for what they have done so far.

Yet, some may argue that it is not difficult to mobilise the support for recovery efforts from the international community, immediately after any major disaster, and the real challenge is to sustain that support through the next few weeks, months and years. Because the recovery process, more specifically the post-recovery reconstruction process, requires long-term support. So, the government agencies should start immediately to focus on, in addition to initial disaster relief, a longer-term strategy for reconstruction. This is important because in a few weeks’ time, the focus of the global community may shift elsewhere … to another crisis in another corner of the world. Before that happens, the government should take initiatives to get the support from development partners on appropriate policy measures, including exceptional trade preferences, to help Sri Lanka in the recovery efforts through the medium and the long term.

Use of Trade Preferences to support recovery and reconstruction

In the past, the United States and the European Union used exceptional enhanced trade preferences as part of the assistance packages when countries were devastated by natural disasters, similar to Cyclone Ditwah. For example:

  • After the devastating floods in Pakistan, in July 2010, the EU granted temporary, exceptional trade preferences to Pakistan (autonomous trade preferences) to aid economic recovery. This measure was a de facto waiver on the standard EU GSP (Generalised Scheme of Preferences) rules. The preferences, which were proposed in October 2010 and were applied until the end of 2013, effectively suspended import duties on 75 types of goods, including textiles and apparel items. The available studies on this waiver indicate that though a significant export hike occurred within a few months after the waiver became effective it did not significantly depress exports by competing countries. Subsequently, Pakistan was granted GSP+ status in 2014.

  • Similarly, after the 2015 earthquakes in Nepal, the United States supported Nepal through an extension of unilateral additional preferences, the Nepal Trade Preferences Programme (NTPP). This was a 10-year initiative to grant duty-free access for up to 77 specific Nepali products to aid economic recovery after the 2015 earthquakes. This was also a de facto waiver on the standard US GSP rules.
  • Earlier, after Hurricanes Mitch and Georges caused massive devastation across the Caribbean Basin nations, in 1998, severely impacting their economies, the United States proposed a long-term strategy for rebuilding the region that focused on trade enhancement. This resulted in the establishment of the US Caribbean Basin Trade Partnership Act (CBTPA), which was signed into law on 05 October, 2000, as Title II of the Trade and Development Act of 2000. This was a more comprehensive facility than those which were granted to Pakistan and Nepal.

What type of concession should Sri Lanka request from our development partners?

Given these precedents, it is appropriate for Sri Lanka to seek specific trade concessions from the European Union and the United States.

In the European Union, Sri Lanka already benefits from the GSP+ scheme. Under this arrangement Sri Lanka’s exports (theoretically) receive duty-free access into the EU markets. However, in 2023, Sri Lanka’s preference utilisation rate, that is, the ratio of preferential imports to GSP+ eligible imports, stood at 59%. This was significantly below the average utilisation of other GSP beneficiary countries. For example, in 2023, preference utilisation rates for Bangladesh and Pakistan were 90% and 88%, respectively. The main reason for the low utilisation rate of GSP by Sri Lanka is the very strict Rules of Origin requirements for the apparel exports from Sri Lanka. For example, to get GSP benefits, a woven garment from Sri Lanka must be made from fabric that itself had undergone a transformation from yarn to fabric in Sri Lanka or in another qualifying country. However, a similar garment from Bangladesh only requires a single-stage processing (that is, fabric to garment) qualifies for GSP. As a result, less than half of Sri Lanka’s apparel exports to the EU were ineligible for the preferences in 2023.

Sri Lanka should request a relaxation of this strict rule of origin to help economic recovery. As such a concession only covers GSP Rules of Origin only it would impact multilateral trade rules and would not require WTO approval. Hence could be granted immediately by the EU.

United States

Sri Lanka should submit a request to the United States for (a) temporary suspension of the recently introduced 20% additional ad valorem duty and (b) for a programme similar to the Nepal Trade Preferences Programme (NTPP), but designed specifically for Sri Lanka’s needs. As NTPP didn’t require WTO approval, similar concessions also can be granted without difficulty.

Similarly, country-specific requests should be carefully designed and submitted to Japan and other major trading partners.

Lasting power and beauty of words

Published

on

Novelists, poets, short story writers, lyricists, politicians and columnists use words for different purposes. While some of them use words to inform and elevate us, others use them to bolster their ego. If there was no such thing called words, we cannot even imagine what will happen to us. Whether you like it or not everything rests on words. If the Penal Code does not define a crime and prescribe a punishment, judges will not be able to convict criminals. Even the Constitution of our country is a printed document.

A mother’s lullaby contains snatches of sweet and healing words. The effect is immediate. The baby falls asleep within seconds. A lover’s soft and alluring words go right into his or her beloved. An army commander’s words encourage soldiers to go forward without fear. The British wartime Prime Minister Winston Churchill’s words still ring in our ears: “… we shall defend our Island, whatever the cost may be, we shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields and in the streets, we shall fight in the hills; we shall never surrender …”

Writers wax eloquent on love. English novelist John Galsworthy wrote: “Love is no hot-house flower, but a wild plant, born of a wet night, born of an hour of sunshine; sprung from wild seed, blown along the road by a wild wind. A wild plant that, when it blooms by chance within the hedge of our gardens, we call a flower; and when it blooms outside we call a weed; but flower or weed, whose scent and colour are always wild.” While living in a world dominated by technology, we often hear a bunch of words that is colourless and often cut to verbal ribbons – “How R U” or “Luv U.” Such words seem to squeeze the life out of language.

Changing medium

Language is a constantly changing medium. New words and forms arrive and old ones die out. Whoever thought that the following Sinhala words would find a place in the Oxford English Dictionary? “Asweddumize, Avurudu, Baila, Kiribath, Kottu Roti, Mallung, Osari, Papare, Walawwa and Watalappan.” With all such borrowed words the English language is expanding and remains beautiful. The language helps us to express subtle ideas clearly and convincingly.

You are judged by the words you use. If you constantly use meaningless little phrases, you will be considered a worthless person. When you read a well-written piece of writing you will note how words jump and laugh on the paper or screen. Some of them wag their tails while others stand back like shy village belles. However, they serve a useful purpose. Words help us to write essays, poems, short stories and novels. If not for the beauty of the language, nobody will read what you write.

If you look at the words meaningfully, you will see some of them tap dancing while others stand to rigid attention. Big or small, all the words you pen form part of the action or part of the narrative. The words you write make your writing readable and exciting. That is why we read our favourite authors again and again.

Editorials

If a marriage is to succeed, partners should respect and love each other. Similarly, if you love words, they will help you to use them intelligently and forcefully. A recent survey in the United States has revealed that only eight per cent of people read the editorial. This is because most editorials are not readable. However, there are some editorials which compel us to read them. Some readers collect such editorials to be read later.

Only a lover of words would notice how some words run smoothly without making a noise. Other words appear to be dancing on the floor. Some words of certain writers are soothing while others set your blood pounding. There is a young monk who is preaching using simple words very effectively. He has a large following of young people addicted to drugs. After listening to his preaching, most of them have given up using illegal drugs. The message is loud and clear. If there is no demand for drugs, nobody will smuggle them into the country.

Some politicians use words so rounded at the edges and softened by wear that they are no longer interesting. The sounds they make are meaningless and listeners get more and more confused. Their expressions are full of expletives the meaning of which is often soiled with careless use of words.

Weather-making

Some words, whether written or spoken, stick like superglue. You will never forget them. William Vergara in his short essay on weather-making says, “Cloud-seeding has touched off one of the most baffling controversies in meteorological history. It has been blamed for or credited with practically all kinds of weather. Some scientists claim seeding can produce floods and hail. Others insist it creates droughts and dissipates clouds. Still others staunchly maintain it has no effect at all. The battle is far from over, but at last one clear conclusion is beginning to emerge: man can change the weather, and he is getting better at it.”

There are words that nurse the ego and heal the heart. The following short paragraph is a good example. S. Radhakrishnan says, “In every religion today we have small minorities who see beyond the horizon of their particular faith, not through religious fellowship is possible, not through the imposition of any one way on the whole but through an all-inclusive recognition that we are all searchers for the truth, pilgrims on the road, that we all aim at the same ethical and spiritual standard.”

There are some words joined together in common phrases. They are so beautiful that they elevate the human race. In the phrase ‘beyond a shadow of doubt’, ‘a shadow’ connotes a dark area covering light. ‘A doubt’ refers to hesitancy in belief. We use such phrases blithely because they are exquisitely beautiful in their structure. The English language is a repository of such miracles of expression that lead to deeper understanding or emphasis.

Social media

Social media use words powerfully. Sometimes they invent new words. Through the social media you can reach millions of viewers without the intervention of the government. Their opinion can stop wars and destroy tyrants. If you use the right words, you can even eliminate poverty to a great extent.

The choice of using powerful words is yours. However, before opening your mouth, tap the computer, unclip a pen, write a lyric or poem, think twice of the effect of your writing. When you talk with a purpose or write with pleasure, you enrich listeners and readers with your marvellous language skills. If you have a command of the language, you will put across your point of view that counts. Always try to find the right words and change the world for a better place for us to live.

Why Sri Lanka Still Has No Doppler Radar – and Who Should Be Held Accountable

Published

on

Eighteen Years of Delay:

Cyclone Ditwah has come and gone, leaving a trail of extensive damage to the country’s infrastructure, including buildings, roads, bridges, and 70% of the railway network. Thousands of hectares of farming land have been destroyed. Last but not least, nearly 1,000 people have lost their lives, and more than two million people have been displaced. The visuals uploaded to social media platforms graphically convey the widespread destruction Cyclone Ditwah has caused in our country.

The purpose of my article is to highlight, for the benefit of readers and the general public, how a project to establish a Doppler Weather Radar system, conceived in 2007, remains incomplete after 18 years. Despite multiple governments, shifting national priorities, and repeated natural disasters, the project remains incomplete.

Over the years, the National Audit Office, the Committee on Public Accounts (COPA), and several print and electronic media outlets have highlighted this failure. The last was an excellent five-minute broadcast by Maharaja Television Network on their News First broadcast in October 2024 under a series “What Happened to Sri Lanka”

The Agreement Between the Government of Sri Lanka and the World Meteorological Organisation in 2007.

The first formal attempt to establish a Doppler Radar system dates back to a Trust Fund agreement signed on 24 May 2007 between the Government of Sri Lanka (GoSL) and the World Meteorological Organisation (WMO). This agreement intended to modernize Sri Lanka’s meteorological infrastructure and bring the country on par with global early-warning standards.

The World Meteorological Organisation (WMO) is a specialized agency of the United Nations established on March 23, 1950. There are 193 member countries of the WMO, including Sri Lanka. Its primary role is to promote the establishment of a worldwide meteorological observation system and to serve as the authoritative voice on the state and behaviour of the Earth’s atmosphere, its interaction with the oceans, and the resulting climate and water resources.

According to the 2018 Performance Audit Report compiled by the National Audit Office, the GoSL entered into a trust fund agreement with the WMO to install a Doppler Radar System. The report states that USD 2,884,274 was deposited into the WMO bank account in Geneva, from which the Department of Metrology received USD 95,108 and an additional USD 113,046 in deposit interest. There is no mention as to who actually provided the funds. Based on available information, WMO does not fund projects of this magnitude.

The WMO was responsible for procuring the radar equipment, which it awarded on 18th June 2009 to an American company for USD 1,681,017. According to the audit report, a copy of the purchase contract was not available.

Monitoring the agreement’s implementation was assigned to the Ministry of Disaster Management, a signatory to the trust fund agreement. The audit report details the members of the steering committee appointed by designation to oversee the project. It consisted of personnel from the Ministry of Disaster Management, the Departments of Metrology, National Budget, External Resources and the Disaster Management Centre.

The Audit Report highlights failures in the core responsibilities that can be summarized as follows:

· Procurement irregularities—including flawed tender processes and inadequate technical evaluations.

· Poor site selection

—proposed radar sites did not meet elevation or clearance requirements.

· Civil works delays

—towers were incomplete or structurally unsuitable.

· Equipment left unused

—in some cases for years, exposing sensitive components to deterioration.

· Lack of inter-agency coordination

—between the Meteorology Department, Disaster Management Centre, and line ministries.

Some of the mistakes highlighted are incomprehensible. There is a mention that no soil test was carried out before the commencement of the construction of the tower. This led to construction halting after poor soil conditions were identified, requiring a shift of 10 to 15 meters from the original site. This resulted in further delays and cost overruns.

The equipment supplier had identified that construction work undertaken by a local contractor was not of acceptable quality for housing sensitive electronic equipment. No action had been taken to rectify these deficiencies. The audit report states, “It was observed that the delay in constructing the tower and the lack of proper quality were one of the main reasons for the failure of the project”.

In October 2012, when the supplier commenced installation, the work was soon abandoned after the vehicle carrying the heavy crane required to lift the radar equipment crashed down the mountain. The next attempt was made in October 2013, one year later. Although the equipment was installed, the system could not be operationalised because electronic connectivity was not provided (as stated in the audit report).

In 2015, following a UNOPS (United Nations Office for Project Services) inspection, it was determined that the equipment needed to be returned to the supplier because some sensitive electronic devices had been damaged due to long-term disuse, and a further 1.5 years had elapsed by 2017, when the equipment was finally returned to the supplier. In March 2018, the estimated repair cost was USD 1,095,935, which was deemed excessive, and the project was abandoned.

COPA proceedings

The Committee on Public Accounts (COPA) discussed the radar project on August 10, 2023, and several press reports state that the GOSL incurred a loss of Rs. 78 million due to the project’s failure. This, I believe, is the cost of constructing the Tower. It is mentioned that Rs. 402 million had been spent on the radar system, of which Rs. 323 million was drawn from the trust fund established with WMO. It was also highlighted that approximately Rs. 8 million worth of equipment had been stolen and that the Police and the Bribery and Corruption Commission were investigating the matter.

JICA support and project stagnation

Despite the project’s failure with WMO, the Japan International Cooperation Agency (JICA) entered into an agreement with GOSL on June 30, 2017 to install two Doppler Radar Systems in Puttalam and Pottuvil. JICA has pledged 2.5 billion Japanese yen (LKR 3.4 billion at the time) as a grant. It was envisaged that the project would be completed in 2021.

Once again, the perennial delays that afflict the GOSL and bureaucracy have resulted in the groundbreaking ceremony being held only in December 2024. The delay is attributed to the COVID-19 pandemic and Sri Lanka’s economic crisis.

The seven-year delay between the signing of the agreement and project commencement has led to significant cost increases, forcing JICA to limit the project to installing only one Doppler Radar system in Puttalam.

Impact of the missing radar during Ditwah

As I am not a meteorologist and do not wish to make a judgment on this, I have decided to include the statement issued by JICA after the groundbreaking ceremony on December 24, 2024.

In partnership with the Department of Meteorology (DoM), JICA is spearheading the establishment of the Doppler Weather Radar Network in the Puttalam district, which can realize accurate weather observation and weather prediction based on the collected data by the radar. This initiative is a significant step in strengthening Sri Lanka’s improving its climate resilience including not only reducing risks of floods, landslides, and drought but also agriculture and fishery“.

Based on online research, a Doppler Weather Radar system is designed to observe weather systems in real time. While the technical details are complex, the system essentially provides localized, uptotheminute information on rainfall patterns, storm movements, and approaching severe weather. Countries worldwide rely on such systems to issue timely alerts for monsoons, tropical depressions, and cyclones. It is reported that India has invested in 30 Doppler radar systems, which have helped minimize the loss of life.

Without radar, Sri Lanka must rely primarily on satellite imagery and foreign meteorological centres, which cannot capture the finescale, rapidly changing weather patterns that often cause localized disasters here.

The general consensus is that, while no single system can prevent natural disasters, an operational Doppler Radar almost certainly would have strengthened Sri Lanka’s preparedness and reduced the extent of damage and loss.

Conclusion

Sri Lanka’s inability to commission a Doppler Radar system, despite nearly two decades of attempts, represents one of the most significant governance failures in the country’s disastermanagement history.

Audit findings, parliamentary oversight proceedings, and donor records all confirm the same troubling truth: Sri Lanka has spent public money, signed international agreements, received foreign assistance, and still has no operational radar. This raises a critical question: should those responsible for this prolonged failure be held legally accountable?

Now may not be the time to determine the extent to which the current government and bureaucrats failed the people. I believe an independent commission comprising foreign experts in disaster management from India and Japan should be appointed, maybe in six months, to identify failures in managing Cyclone Ditwah.

However, those who governed the country from 2007 to 2024 should be held accountable for their failures, and legal action should be pursued against the politicians and bureaucrats responsible for disaster management for their failure to implement the 2007 project with the WMO successfully.

Sri Lanka cannot afford another 18 years of delay. The time for action, transparency, and responsibility has arrived.
