Over the past few months, there has been considerable interests among not only geoscientists and engineers but also ordinary people in the potential risks faced by two of the major hydropower projects constructed in the central highlands, namely the Victoria and Kotmale projects. These projects have come into the limelight owing to some minor seismic tremors felt in the Victoria area, together with the recent announcement of the intention to raise the Kotmale dam. Alarm bells are ringing that seismic activity may jeopardize the integrity of the Victoria dam and the raising of Kotmale may result in dam failure. Should these dams fail, they will be the biggest manmade disasters our country has ever faced. This risk has prompted suggestions from the people higher up that we should seek advice from foreign experts.

Various opinions from the leading geoscientists of the country, regarding the causes and effects of this unusual activity were aired through the media recently. Some have attributed the seismic tremors to limestone quarrying in the Victoria reservoir area, some as the result of neo-tectonic movements of the central highlands, yet some others said they are reservoir-induced earthquakes. Those who are interested in the fundamentals of such activity may find the presentation in this link useful (https://www.youtube.com/watch?v=7huzvuU9TEI).

The intention of this article is to provide an insight into the geotechnical issues that influence the Kotmale Project, the risks, and to address some misconceptions people may have regarding the project. I take the liberty of writing on these issues as a person who has an in-depth knowledge of the Project by working from the site investigation phase through to construction completion, the later years as the Senior Engineering Geologist, leading the project geoscientist team.

 

The Project

Kotmale was meant to be the main upstream storage reservoir under the Mahaweli development scheme launched in the 1960s. It will regulate the Mahaweli waters, while providing a substantial energy component. The capacity of the reservoir will be more than doubled by the proposed raising of the dam, approximately by 30 m. The project was inaugurated in 1979 and funded by Sweden. Sir William Halcrow and Partners of UK (Halcrow) with Central Engineering Consultancy Bureau of Sri Lanka (CECB) was the design engineer and Skanska of Sweden was the contractor.

 

Geology of the Project Area

To understand the project risks, it is essential to understand the geology and structure of the project area. The area is underlain by Pre-Cambrian age metamorphic rocks comprising predominantly of two rock types, charnokite (gneiss) and crystalline limestone (dolomite or marble) with minor quartzites. The limestone is sandwiched between layers of charnokite gneiss.

The rock units are folded into a gentle anticlinorium (an arch like structure-convex shape) which has a slight plunge downstream. The axis of the anticline trends northwest and falls on the right abutment in the dam area. As such the dam foundation rocks have a slight inclination (15°-25°) downstream and into the abutments.

Charnokite is a very strong resistant rock, which does not breakdown easily while limestone deteriorates and erodes more easily. The initial site investigation drilling in the Kotmale valley found limestone thickness varied from 20 m to 130 m within the project area.

The limestone consists mainly of calcium carbonate (CaCO3) and partly magnesian carbonate (MgCO3). Carbonates dissolves in acidic water (acid rain) and forms solution cavities. These cavities have the potential to create leaks from the reservoirs.

 

Formation of the Kotmale Valley

The Kotmale valley is an amphitheatre-like valley reshaped by the erosional activity of the Kotmale Oya for millennia. It is approximately 5 km wide at the widest point, is surrounded by high rock cliffs up to 300 m high on both flanks, which converge at the Kadadora village; the site of the dam construction. The valley forming process was a combination of differential weathering and erosion of the underlying limestone unit, resulting in the collapse of overlying more resistant rock units. The basal slopes of the cliffs consist of accumulated debris of rocks and soil derived from the cliffs (termed as scree or talus). Historically these talus slopes were in perpetual slow motion (creep) towards the river. They were subjected to numerous landslides, typically during or after heavy rain events. Generally, the Kotmale valley was infamous for landslide activity.

 

History of Kotmale Project investigations

The location of the dam site had been selected for the seemingly favourable topography formed by the converging valley flanks. One of the first jobs assigned to me when I joined the CECB in 1978 as a young engineering geologist, was to map four exploratory tunnels driven into the abutments of the proposed dam and report the rock conditions. Our evaluation indicated the left abutment had very poor rock conditions not suitable for a dam foundation.

In 1979, to evaluate the landslide risk to the project, Halcrow carried out a landslide survey of the project area. This survey was done due to the frequent landslide activity in the Kothmale area, and its similarities to the Vajont Dam disaster that occurred in Italy in 1963, which wiped out several downstream towns resulting about 2500 deaths.

This study identified the left abutment as a settled block (subsided en mass); limestone solution the likely cause. It strongly recommended to move the damsite downstream and monitor the impressive cliffs on the left flank of the valley for potential movements.

 

Evaluation by a panel of experts

As these findings were major issues impacting the viability of the Project, the Mahaweli Authority of Sri Lanka as the owner of the project, in early 1980 engaged a panel of foreign experts who were the leaders in the fields of rock and soil mechanics, to evaluate the potential issues and provide recommendations. This panel endorsed the relocation of the damsite.

Subsequently, the dam axis was moved approximately 200 m downstream from the original location.

 

Nature and distribution of the limestone

At the new location, the limestone was at a much greater depth below the dam foundation compared to the original site as shown in Figure 1. Even so, solution cavities were observed in the contact zone and within the limestone itself identified by drilling and close circuit television (CCTV) inspections carried out in the drillholes. Our best estimate indicated small cavities, however a drillhole represents only a small area, therefore the existence of larger cavities could not be ruled out.

 

Leakage through cavernous limestone is widespread from the reservoirs built in our hill country. The Samanalawewa Project is the best example where significant leakage had been occurring through a cavernous limestone under the right abutment since the impoundment, which could not be sealed.

 

Continuity of the Kotmale limestone

Investigations were carried out to establish the continuity of the Kotmale limestone to downstream areas in view of potential leakage which were inconclusive. The recent geological map for the Kandy-Nuwara-Eliya districts (GSMB), I am convinced that the Kotmale limestone continues to Gampola-Atabage Valley and further to the Victoria Reservoir as a major rock unit. The limestone quarrying in the Victoria Reservoir area occurs in the same unit, which caused the recent furore about seismic events allegedly caused by blasting. Whilst I do not believe there is (or will be) significant leakage from Kotmale Reservoir, future raising of the dam may enhance leakage if it exists which needs evaluation.

 

Water tightness of the dam foundation

To eliminate the risk of water leakage through the limestone under the dam foundation, it was extensively grouted from a grouting gallery constructed below the dam level (see Figure 1). Generally, the grout intakes were low. Nevertheless, few holes required significant amounts of grout before they could be sealed. Subsequent water pressure testing indicated the limestone unit was properly sealed and the foundation was watertight.

 

Monitoring of the cliffs and other landslides

During the initial impoundment, the cliffs were inspected by walkover surveys and by periodic monitoring with geodetic surveying. Movements of any significance, precursor of an impending major failure were not recorded during the early years after construction.

 

Reservoir Induced Seismicity (RIS)

One important consideration in the construction of large reservoirs is the potential for reservoir induced seismicity (RIS). RIS is the incidence of earthquakes triggered due to the impoundment of water behind a dam. A simplistic explanation is that reservoirs trigger earth tremors due to the load of water which could activate otherwise dormant faults, the energy released causing earth tremors.

Halcrow decided to investigate the risk of movement of some major structures present in the Kotmale reservoir area upon impoundment, which could potentially induce seismic events. Consequently, a micro-seismic monitoring network (MSMN) consisting of four monitoring stations was established around Kotmale project in 1981. The monitoring program was managed by the CECB and continued until the early 90s.

Published data (Fernando & Kulasinghe 1985) show that the maximum event recorded at Kotmale during the first two and half years of monitoring, was an event of 2.25 magnitude (Richter Scale), located far away from the project area. The monitoring led to the conclusion that the potential for RIS at Kotmale was extremely low or non-existent. However, in view of the recent seismic events recorded around Victoria, it will be prudent to revisit the monitoring records from the Kotmale network, presumably archived by the CECB.

 

Potential risks from future raising

The Kotmale project infrastructure, were designed and constructed for future raising. Theraised dam simply achieves the original vision of the project, as the main upstream storage reservoir and increases power output.

 

In my opinion the geotechnical risks arising from the raising of the Kotmale dam are as follows:

= The raised water level in the reservoir will fully inundate the scree slopes and reach the base of the left bank cliffs with potential to create major landslides. Cliff monitoring should be re-established using modern methods such as satellite based synthetic aperture radar interferometry (inSAR).

= There is potential for leakage through the limestone with raised water levels. All evidence suggests the limestone under the dam was properly sealed. Leakage from the reservoir flanks cannot be prevented, which is not a fatal flaw to the project. Requirement for abutment sealing should be revisited.

= It will be useful to re-establish the monitoring program of stream gauging in the Gampola-Atabage valley to investigate if any leakage will occur from Kotmale to Atabage valley. This should be initiated before the dam raising.

= All evidence points to reservoir induced seismicity is a non-issue for Kotmale Project.

 

Finally, I strongly advocate the raising of the dam for the following reasons:

 

= The original project infrastructure was developed with the intention of future raising.

= There are potential risks but not fatal flaws to the viability of the Project. These risks can be mitigated.

= People were evacuated from their ancestral lands going under the reservoir and if the project is not completed as originally intended, then this relocation of people was without merit and a grave injustice to them.

= The country unnecessarily lost approximately 30 MW of power for more than 35 years.

 

The potential risks with the raising of the Kotmale dam discussed here need to be evaluated, and if the need arise, they should be mitigated and managed using local expertise. In my opinion, what Sri Lanka lacks is good project managers vital in successful implementation of projects of such enormous national importance. In hindsight, the Kotmale reservoir should have been built to the full capacity at the first instance.

Citizenship, Devolution, Land and Language: The Vicarious Legacies of SJV Chelvanayakam

Published

on

From left GG Ponnambalam, SJV Chelvanayakam and M. Tiruchelvam

SJV Chelvanayakam, the founder leader of the Ilankai Thamil Arasu Kadchi, aka Ceylon Tamil Federal Party, passed away 49 years ago on 26 April 1977. There were events in Sri Lanka and other parts of the world where Tamils live, to commemorate his memory and his contributions to Tamil society and politics. His legacy is most remembered for his espousal of the cause of federalism and his commitment to pursuing it solely through non-violent politics. Chelvanayakam’s political life spanned a full 30 years from his first election as MP for Kankesanthurai in 1947 until his death in 1977.

Under the rubric of federalism, Chelvanayakam formulated what he called the four basic demands of the Tamil speaking people, a political appellation he coined to encompass – the Sri Lankan Tamils, Sri Lankan Muslims and the hill country Tamils (Malaiyaka Tamils). The four demands included the restoration of the citizenship rights of the hill country Tamils; cessation of state sponsored land colonisation in the North and East; parity of status for the Sinhala and Tamil languages; and a system of regional autonomy to devolve power to the northern and eastern provinces.

High-minded Politics

Although the four basic demands that Chelvanayakam articulated were not directly delivered upon during his lifetime, they became part of the country’s political discourse and dynamic to such an extent that they had to be dealt with, one way or another, even after his death. So, we can call these posthumous developments as Chelvanayakam’s vicarious legacies. There is more to his legacy. He belonged to a category of Sri Lankans, Sinhalese, Tamils and Muslims, who took to politics, public life, public service, and even private business with a measure of high-mindedness that was almost temperamental and not at all contrived. Chelvanayakam personified high-minded politics. But he was not the only one. There were quite a few others in the 20th century. There have not been many since.

Born on 31 March 1898, Chelvanayakam was 49 years old when he entered parliament. He was not an upstart school dropout dashing into politics or coming straight out of the university, or even a hereditary claimant, but a self-made man, an accomplished lawyer, a King’s Counsel, later Queen’s Counsel, and was widely regarded as one of the finest civil lawyers of his generation. He was a serious man who took to politics seriously. Howard Wriggins, in his classic 1960 book, “Ceylon: Dilemmas of a New Nation”, called Chelvanayakam “the earnest Christian lawyer.”

Chelvanayakam’s professional standing, calm demeanour, his personal qualities of sincerity and honesty, and his friendships with men of the calibre of Sir Edward Jayatilleke KC (Chief Justice, 1950-52), H.V. Perera QC, P. Navaratnarajah, QC, and K.C. Thangarajah, were integral to his politics. The four of them were also mutual friends of Prime Minister SWRD Bandaranaike and they played a part in the celebrated consociational achievement in 1957, called the B-C Pact.

Chelvanayakam effortlessly combined elite consociationalism with grass roots politics and mass movements. He led the Federal Party both as a democratic organization and an open movement. Chelvanayakam and the Federal Party used parliament as their forum to present their case, the courts to fight for their rights, and took to organizing non-violent protests, political pilgrimages and satyagraha campaigns. He was imprisoned in Batticaloa, detained in Panagoda, and was placed under house arrest several times. His Alfred House Gardens neighbours in Colombo used to wonder why the government and the police were after him, of all people, and why wouldn’t they do something about his four boisterous, but studious, sons!

He was a rare politician who filed his own election petition when he was defeated in the 1952 election, his first as the leader of the Federal Party, and was rewarded with punitive damages by an exacting judge. He had to borrow money from Sir Edward Jayatilleke to pay damages. The common practice for losing candidates was to file vexatious petitions in the name of one of their supporters with no asset to pay legal costs. Chelvanayakam was too much of a principled man for that. As a matter of a different principle, the two old Left parties never challenged election losses in court, but Dr. Colvin R de Silva singled out Chelvanayakam’s uniqueness for praise in parliament, in the course of a debate on amendments to the country’s election laws in 1968.

Disenfranchisement & Disintegration

Although he became an MP in 1947, Chelvanayakam had been associated with GG Ponnambalam and the Tamil Congress Party for a number of years. GG was the flamboyant frontliner, SJV the quiet mainstay behind. Tamil politics at that time was all about representation. In fact, all politics in Sri Lanka has been all about representation all the time. It started when British colonial rulers began nominating local (Sinhala, Tamil, Muslim) representatives to quasi legislative bodies, and it became a contentious political matter after the introduction of universal franchise in 1931.

Communal representation was conveniently made to look ugly by those who themselves were politically communal. Indeed, under colonial rule, if not later too, Sri Lankans were a schizophrenic society where most Sinhalese, Tamils and Muslims were socially friendly, but politically communal. The underlying premise to the fight over representation was that British colonialists were not leaving in a hurry and they were there to stay and rule for a long time. Hence the jostling for positions under a foreign master. It was in this context that Ponnambalam made his celebrated 50-50 pitch for balanced representation between the Sinhalese, on the one hand, and all the others – Tamils, Muslims, Indian Tamils – combined on the other. It was a perfectly rational proposition, but it was also perfectly poor politics.

But independence came far sooner than expected. The Soulbury Constitution was set up not for a continuing colonial state, but as the constitution for an independent new Ceylon. So, the argument for balanced representation became irrelevant in the new circumstances. The new Soulbury Constitution was enacted in 1945, general elections were held in 1947, a new parliament was elected, and Ceylon became independent in 1948. SJV Chelvanayakam was among the seven Tamil Congress MPs elected to the first parliament led by GG Ponnambalam.

The Tamil Congress campaigned in the 1947 election against accepting the Soulbury Constitution and for a vaguely formulated mandate “to cooperate with any progressive Sinhalese party which would grant the Tamil their due rights.” But what these rights are was not specified. In a Feb. 5, 1946 speech in Jaffna, Ponnambalam specifically proposed “responsive cooperation between the communities” – not parties – and advocated “a social welfare policy” to benefit not only the poor masses of Tamils but also the large masses of the Sinhalese.

So, when Ponnambalam and four of the seven Tamil Congress MPs decided to join the government of DS Senanayake with Ponnambalam accepting the portfolio of the Minister of Industries, Industrial Research and Fisheries, they were opposed by Chelvanayakam and two other Tamil Congress MPs. The immediate context for this split was the Citizenship question that arose soon after independence when DS Senanayake’s UNP government introduced the Ceylon Citizenship Bill in parliament. The purpose and effect of the bill was to deprive the estate Tamils of Indian origin (then numbering about 780,000) of their citizenship. Previously the government had got parliament to enact the Elections Act to stipulate that only citizens can vote in national elections. In one stroke, the whole working population of the plantations was disenfranchised.

GG Ponnambalam and all seven Tamil Congress MPs voted against the two bills. Joining them in opposition were the six MPs from the Ceylon Indian Congress representing the Malaiyaka Tamils and 18 Sinhalese MPs from the Left Parties. The Citizenship Bill was passed in Parliament on 20 August 1948. Ponnambalam called it a dark day for Ceylon and accused Senanayake of racism. But less than a month later, on September 3, 1948, he joined the Senanayake cabinet as a prominent minister and the government’s principal defender in parliamentary debates. Dr. NM Perera once called Ponnambalam “the devil’s advocate from Jaffna.”

Chelvanayakam remained in the opposition with two of his Congress colleagues. A little over an year later, on December 18, 1949, Chelvanayakam founded the Ilankai Tamil Arasu Kadchi, Federal Party in English. Not long after, joining Chelvanayakam in the opposition was SWRD Bandaranaike, who broke away from the UNP government over succession differences and went on to form another new political party, the Sri Lanka Freedom Party. As was his wont as a Marxist to see trends and patterns in politics, Hector Abhayavardhana saw the breakaways of Chelvanayakam and Bandaranaike, as well as the emergence of Thondaman as the leader of the disenfranchised hill country Tamils, as symptoms of a disintegrating society as it was transitioning from colonial rule to independence.

Abhayavardhana saw the Citizenship Act as the political trigger of this disintegration in the course of which “what was set up for the purpose of a future nation ended in caricature as a Sinhalese state.” Chelvanayakam may have agreed with this assessment even though he was located at the right end of the ideological continuum. “Ideologically, SJV is to the right of JR,” was part of political gossip in the old days. He saw “seeds of communism” in Philip Gunawardena’s Paddy Lands Act. For all their differences, Chelvanayakam and Ponnambalam were united in one respect – as unrepentant opponents of Marxism.

The Four Demands

Chelvanayakam had his work cut out as the leader of a new political party and pitting himself against a formidable political foe like Ponnambalam with all the ministerial resources at his disposal. Chelvanayakam may not have quite seen it that way. Rather, he saw his role as a matter of moral duty to fill the vacuum created by what he believed to be Ponnambalam’s betrayal, and to provide new leadership to a people who were at the crossroads of uncertainty after the unexpectedly early arrival of independence.

He set about his work by expanding his political constituency to include not only the island’s indigenous Tamils, but also the Muslims and the Tamil plantation workers from South India – as the island’s Tamil speaking people. It was he who vigorously introduced the disenfranchised Indian Tamils as hill country Tamils. In the aftermath of the Citizenship Act and disenfranchisement, restoring their citizenship rights became an obvious first demand for the new Party.

Having learnt the lesson from Ponnambalam’s failed 50-50 demand, Chelvanayakam territorialized the representation question by identifying the northern and eastern provinces as “traditional Tamil homelands,” and adding a measure regional autonomy to make up for the shortfall in representation at the national level in Colombo. To territorialization and autonomy, he added the cessation of state sponsored land colonization especially in the eastern province. Chelvanayakam and the Federal Party painstakingly explained that they were by no means opposed to Sinhalese voluntarily living in Tamil areas, either as a matter of choice, pursuing business or as government and private sector employees, but the nuancing was quite easily lost in the political shouting match.

The fourth demand, after citizenship, regional autonomy, and land, was about language. Language was not an issue when Chelvanayakam started the Federal Party. But he pessimistically predicted that sooner or later the then prevailing consensus, based on a State Council resolution, over equality between the two languages would be broken. He was proved right, sooner than later, and language became the explosive question in the 1956 election. As it turned out, the UNP government was thrown out, SWRD Bandaranaike led a coalition of parties to victory and government in the south, while SJV Chelvanayakam won a majority of the seats in the North and East, including two Muslims from Kalmunai and Pottuvil.

After the passage of the Sinhala Only Act on June 5, 1956, the Federal Party launched a political pilgrimage and mobilized a convention that was held in Trincomalee in the month of August. The four basic demands were concretized at the convention, viz., citizenship restoration for the hill country Tamils, parity of status for the Sinhala and Tamil languages, the cessation of state sponsored land colonization, and a system of regional autonomy in the Northern and Eastern Provinces.

The four demands became the basis for the Bandaranaike-Chelvanayakam agreement – the B-C Pact of 1957, and again the agreement between SJV Chelvanayakam and Dudley Senanayake in 1965. The former was abrogated by Prime Minister Bandaranaike under political duress but was not abandoned by him. The latter has been implemented in fits and starts.

The two agreements which should have been constitutionally enshrined, were severely ignored in the making of the 1972 Constitution and the 1978 Constitution – with the latter learning nothing and forgetting everything that its predecessor had inadvertently precipitated. The political precipitation was the rise of Tamil separatism and its companion, Tamil political violence. Ironically, Tamil separatism and violence created the incentive to resolve what Chelvanayakam had formulated and non-violently pursued as the four basic demands of the Tamils.

After his death in 1977, the citizenship question has finally been resolved. The 13th Amendment to the 1978 Constitution that was enacted in 1987 resolved the language question both in law and to an appreciable measure in practice. The same amendment also brought about the system of provincial councils, substantially fulfilling the regional autonomy demand of SJV Chelvanayakam. The land question, however, has taken a different turn with state sponsored land colonisation in the east giving way to government security forces sequestering private residential properties of Tamil families in the north, especially in the Jaffna Peninsula.

Further, the future of the Provincial Council system has become uncertain with the extended postponement of provincial elections by four Presidents and their governments, including the current incumbents. The provinces are now being administered by the President through handpicked governors without the elected provincial councils as mandated by the constitution. Imagine a Sri Lanka where there is only an Executive President and no parliament – not even a nameboard one. “What horror!”, you would say. But that is the microcosmic reality today in the country’s nine provinces.

“AI increases profits while reducing un ethical intervention which is proven by Successful Global Business Models”

Artificial Intelligence(AI) is still only a buzz word in the Sri Lankan society, though many wanted to have an awareness of the concept the resources are scares, even still the IT industry has not formulated any awareness programs or a Degree yet to cope with the development. But world education warns that there want be any IT based jobs in future without learning the AI. AI has multiple use in any discipline and it has the ability to increase the efficiency of the work intern cut down the product or the service cost. Below description is how the application of AI can smoother the function of Logistic or the Supply Chain Management.

AI Integrating Procedure for Distribution Systems

Using Artificial Intelligence (AI) in logistics can greatly improve efficiency, reduce costs, and enhance decision-making in simple enhance the profit margins. Below is a structured overview of how AI can be used in logistics, including key applications, tools, and real-world examples. Machine Learning(ML) is the foundation to AI but subsequently develops the capability of absorbing the information from the cloud (IT environment) and produce future behavior or trends by analyzing the fed data to the computers on a certain period of time. In some occasions vendors offer unbelievable discounts by using ML or AI, because it clearly understands the market behavior, human behavior, expiration and many other variables that gives the profits or losses to the product or the service.

Key Areas Where AI is Used in Logistics;

· Demand Forecasting

· Route Optimization

· Warehouse Automation

· Predictive Maintenance

· Inventory Management

· Supply chain Management

· Customer Service with Chat bots

· Fraud Detection and Risk Management

1. Demand Forecasting

AI can analyze historical data, market trends, and external factors (like weather or news) to:

· Predict product demand more accurately

· Optimize inventory levels

· Reduce stockouts or overstocking

Tools: Machine learning models (e.g., time series forecasting) and IT platforms/software like Amazon Forecast, Prophet by Meta. These are the software applications that helps to understand the future trends.

Amazon Forecasting software

Traditional forecasting methods typically rely on statistical modeling, but software like “Chronos” that treats time series data (data collected during a certain period of time) as a language to be modeled and uses a pre-trained FM (forecast Models) to generate forecasts, which similar to how “Large Language Models” (LLMs) generate texts helps you achieve accurate predictions faster, significantly reducing development time compared to traditional methods.

Prophet by Meta

Prophet is a very efficient and accurate procedure for forecasting time series data based on an additive model where non-linear trends are fit with yearly, weekly, and daily seasonality, plus holiday effects. It works best with time series that have strong seasonal effects and several seasons of historical data. This software adds many social, cultural and geographical variables other than internal information to decision making.

2. Route Optimization

AI-powered systems can calculate the most efficient delivery routes in real-time using:

· Traffic data

· Weather conditions

· Delivery time windows

· Vehicle capacity and fuel usage

Example: UPS (one of the largest Logistic companies in the world) uses its ORION system (AI-based) to save millions of gallons of fuel per year.

IT Tools: Google OR-Tools, Route4Me, Mapbox with ML integration.

IBM Maximo is a multi-facet coordinator

The “Route4Me” IT platform automates and integrates mission-critical last mile workflows, empowering route planners, dispatchers, drivers, and managers to take the business to the next level. Distribution networks, passenger transportation networks can achieve much cost reduction by using above platforms. This is a good platform for the Sri Lanka passenger industry to reduce the overheads for the population. In Sri Lanka “Pick me” and “Uber” uses similar platforms in their transportation industry. Whole three wheeler industry can be regulating with this kind of software and transfer benefits to the passengers.

3. Warehouse Automation

AI enables:

· Robotics for picking, packing, and sorting

· Vision systems for scanning and inventory management

· Autonomous forklifts and drones for internal transport

Example: Amazon’s use of “Kiva robots” in fulfillment(distribution) centers.

Kiva Robots in Warehouses

Traditionally, goods are moved around a distribution center using a conveyor system  or by human-operated machines (such as forklifts). In Kiva’s approach, items are stored in portable storage units. When an order is entered into the Kiva database system, the software locates the closest automated guided vehicle to the item and directs it to retrieve it. The mobile robots navigate around the warehouse by following a series of computerized bar-code stickers on the floor. Each drive unit has a sensor that prevents it from colliding with others. When the drive unit reaches the target location, it slides underneath the pod(Pallet) and lifts it off the ground through a corkscrew action. The robot then carries the pod to the specified human operator to pick up the items or subsequently hand over to the “drone” to deliver to the customer. Human intervention is minimal and accordingly overheads are reduced, Sri Lanka needs to achieve this kind of operational level in order to par with the international markets.

4. Predictive Maintenance

Traditionally Sri Lankans are week in maintenance, they basically wait until the machine stops in the other way bureaucratic too are much restrict on the maintenance and the procurement procedure. Applying this kind of maintenance software will eradicate all of these lethargies and the bureaucratic blocks. Subsequently continuing the smooth operations and productions.

AI monitors equipment (vehicles, conveyor belts, etc.) to:

· Predict when they will fail

· Schedule maintenance proactively

· Reduce downtime and repair costs

Tools: IoT(internet of things as cameras, sensors, GPS etc.) sensors + ML models (e.g., anomaly detection), IT platforms like IBM Maximo.

IBM Maximo is a multi-facet coordinator

“From equipment to factories, from fleets to infrastructure, Maximo Application Suite empowers users across verticals to coordinate maintenance and management for a broad range of asset classes”.

5. Supply Chain Visibility

AI can analyze data across the supply chain to:

· Track shipments in real-time

· Identify delays or bottlenecks

· Provide predictive ETAs

📦 Example: DHL (Logistic Company) uses AI to forecast transit delays and offer dynamic ETA updates.

This is an ideal tool for cargo management, ideal for sea ports and the air ports in Sri Lanka. This is one of the grave gray areas in the port system, though the port system is lacking the required information due to that the client has to pay the demurrages and warehouse cost for the ports. Also, cut down unnecessary delays and reduce bribes and corruption at all levels.

6. Inventory Management

AI helps optimize:

· Stock levels across multiple warehouses

· Replenishment timing

· Safety stock calculation

Tools: ERP (Entrepreneur Resource Planning) systems with embedded AI (e.g., SAP, Oracle), custom ML models.

These systems drastically reduce the human intervention and speedup the Supply management process.

7. Customer Service & Chatbots

AI-powered chatbots and virtual assistants can:

· Handle customer queries 24/7

· Track orders

· Provide personalized delivery updates

Tools: Dialogflow, Microsoft Bot Framework, ChatGPT API

Dialogflow

“Dialogflow” is a natural language understanding IT platform that makes it easy to design and integrate a conversational user interface into the mobile app, web application, device, bot, interactive voice response system, and so on. Using Dialogflow, establishments can provide new and engaging ways for users to interact with the product. Dialogflow can analyze multiple types of input from the customers, including text or audio inputs (like from a phone or voice recording). It can also respond to the customers in a couple of ways, either through text or with synthetic speech.

AI Conversational Chatbots Platform

Above IT platforms control the human intervention and reduce the cost of employees. Chatbots are basically efficient than the humans due to the high memory power for the standard customer inquiries. Application to Government sector will reduce the burden for the general public.

8. Fraud Detection & Risk Management

AI detects unusual patterns in:

· Orders

· Transactions

· Supplier behavior

Helps prevent:

· Cargo theft

· Counterfeit goods

· Financial fraud

*”KPMG Clara” for Supply Chain Risk Management

“KPMG Clara” is an AI-powered IT platform offering supply chain analytics, risk detection, and compliance management.

Key Features:

· AI-driven risk modeling

· ESG (Environmental, Social and Governance) and compliance monitoring

· Predictive analytics for disruptions

· Supplier risk scoring

“Geo Analysis” (AI based) IT platform in Supply Chain Access Control

Above IT platform Monitor access patterns across cross-border freight hubs, regional warehouses, and remote carrier logins. “Geo analysis” for supply chain authentication identifies impossible travel, geo-inconsistencies, and spoofed IPs to reduce credential abuse and unauthorized entry into logistics systems. This important IT platform can reduce corruption and many unethical practices, ideal tool for the Sri Lankan Government sector that can curb the mal practices.

Artificial Intelligence (AI) is a remarkable IT tool which can apply in almost all the sectors that can reap the Efficiency and Accuracy. In above paragraphs I have described the application in different stages of the Logistic or the Supply Chain Management. Application of AI tools can be done on stages as initially find the specific pain points pertaining to the supply chain and then, prepare data from the GPS, inventory systems, sales forecasts and supplier records. Subsequently can understand the specific AI platforms and ML models to suit the SCM operation. Further, can apply in a small scale as a pilot project and analyze impact as cost savings or efficiency gains. Once understand the model can roll out to other areas of operations in the establishment.

Final outcome will be “15% reduction in fuel cost, 20% faster deliveries, Increased customer satisfaction”

There may be many negative lobbies since this is new to the many sectors in the country and further ability to proof the corruption but proper education and understanding the world AI based business models, establishments can reach the required goal.

Motherhood is not ‘giving up’

Published

on

Since having my baby, I have been regularly met with the question, “Are you back at work?”

“No,”

I reply. “I am doing my PhD from home.”

Several emotions arise. I feel guilty that I am not back at work, that somehow I should be. I also feel relieved that I can justify my time at home by offering up the PhD as a worthy endeavour. Sometimes, the person responds in surprise, “Oh, so no work?” Other times, they are approving, “How lucky for you and your baby.” Occasionally, there is the advice, “Don’t give up work.”

At the back of my mind are certain thoughts. “Am I not ‘working’? Isn’t the work of motherhood also considered ‘work’? If it isn’t, shouldn’t it be?”

Although the questions, comments, and advice about returning to work are made innocently enough, mostly benevolently, they have prompted me to reflect on the idea of work and motherhood, and how mothers and society view both.

Motherhood, I believe, is a full-time, highly skilled, unpaid job that never ends. All mothers work at least two jobs. They do the work of mothering, and also work in either a paid or unpaid additional role. Many women will do even more. They mother, care for their elderly parents, work a paid job, voluntarily contribute to community building, and try to fit in creative pursuits, hobbies, or ‘self-care’ when they can.

Motherhood requires many skills. You are, effectively, the CEO of your family and home (with hopefully a supportive co-CEO by your side). There is the work of child-rearing, which requires patience, energy, creativity, presence, flexibility, courage, fortitude, knowledge, and the ability to research, learn, and unlearn. You are raising the future. Then there is the work of home and family life, which requires skills in leadership, organisation, prioritisation, delegation, negotiation, financial management, crisis management, and conflict resolution. There is also the internal work of being self-aware, forgiving yourself and others, practicing compassion, and accepting the inherent imperfections of ‘doing it all’.

This work of motherhood is now recognised as ‘unpaid caregiving and domestic work’ and ‘invisible labour’ by international organisations such as the United Nations. It includes physical labour, direct care labour, mental or cognitive labour, and emotional labour, and is mostly the work of women.

I am not complaining. Men have their own unpaid labour. I love being a mother and wife. I view it as a privilege and a blessing. Ideally, the job can also be supported by paid or unpaid help. My point is that the work of women, and specifically mothers, should be recognised and respected, not only by society, but also by women and mothers themselves.

I know it is not just me who has experienced conflicting emotions about ‘giving up’ traditional work to focus on family life. Within my social circle and more widely, mothers describe a loss of self-worth and identity unless they are ‘working mothers’, and feeling embarrassment and guilt when asked the dreaded question, “What do you do?” There is the loss of financial dignity that comes with taking on an unpaid job, no matter how important you may think it is. Dynamics with husbands also need to shift, where both members are viewed as equally valuable to making the business of ‘home’ successful.

Neha Ruch, the author of The Power Pause, is an American brand strategist-turned-full-time stay-at-home mother and home maker, who addresses this very issue. Many of my thoughts for this article are based on her book. She argues that the time a woman wishes to invest in this phase of life, motherhood and family life, is valuable, not just for the children or family unit, but for the mother herself. It is a time for growth, skill-building, and expanding networks and connections.

Often, it leads women in new, creative, and more fulfilling directions, and provides an opportunity for them to re-enter the workforce on their own terms. She also points out that ‘the pause’ is not a luxury for a lucky minority, as many women become the default caregiver for their children if childcare is too costly, or not the preferred option. Through the movement she has created, Ruch provides legitimacy, validation, and structure to this phase of life (because, after all, it is only a phase, not forever) that is often spoken of as mindless, monotonous, and unglamorous, and I am grateful for it.

I suppose what I am saying is, next time you meet a mother, consider asking her, “How are you?”, and next time I am asked what I do, I should proudly declare (using Ruch’s script), “Right now, I am on a career pause and get to be home with my baby, and I am exploring possibilities for the future.”
