Map of Digitisation of Television World wide

Retired Principal Engineer, Digital Transition Division, Australian Communications and Media Authority

A Japanese delegation recently announced the resumption of the previously stalled digital television project in Sri Lanka following a meeting with the newly-elected President Anura Kumara Dissanayake. The commencement of the digitisation project is now imminent.

Once terrestrial television transmissions are digitised in Sri Lanka, it will replace the old analogue terrestrial television forever. Therefore, it is critically important that the final outcome is better than the current analogue television, if not far superior. Setting such a goal prior to the implementation of the project is crucial for its fruitful completion.

To achieve this outcome, deficiencies in the current parameters in the Japanese Digital Plans need to be revisited and appropriately addressed for the benefit of all stakeholders. Otherwise, as it stands today, there is a high potential for rural and regional viewers in Sri Lanka to miss out on the digital coverage. (This is further illustrated below). Such an unwarranted outcome could become a highly ‘politically sensitive’ issue for the new government .

Why Digital

In analogue transmissions, radio waves encounter several problems. When radio waves are subjected to multipath, ghosting images appear on television screen. They are also subjected to cancellation of their own signals and interference.

Digital technology overcomes these analogue transmission weaknesses and, as a huge value addition, is able to carry more information than its analogue counterpart. As this capacity enhancement feature helps carry multiple programmes on one frequency or channel, digital television transmission technology is considered to be highly spectrum productive. Once analogue is switched off, the vacant spectrum that can be harnessed, commonly known as Digital Dividend (DD), becomes an income earner for the Government, as spare spectrum can be sold to Telcos for broadband internet use. Thus, this digitisation project is effectively a self-financing venture for the government and a win-win for all stakeholders.

Stakeholder benefits of digital

Many countries in the world have now moved or are in the process of moving to the digital domain.

Irrespective of the digital television transmission standard adopted in Sri Lanka, benefits of a conversion from analogue to digital television are many for the majority of stakeholders.

These are listed below against the various stakeholders:

*  Government – a significant income from selling the vacant spare spectrum to Telcos, following full conversion to digital, provided appropriate modifications are made to the JICA plan;

*  Broadcasters – increased television channels and scope for increase of advertising revenue;

*  Viewers – increased number of television channels to facilitate a wider selection of content, with True High Definition (True HD) quality and potential 5.1 Surround Sound;

*  Content providers – opportunity to produce a wide range of programmes that are in demand;

*  Production houses – larger revenue from vastly increased niche productions;

*  Creators of social media and other internet-based content – opportunities to develop novel visual and aural media content;

*  Electronic Manufacturing/Testing – opportunities to manufacture digital television receivers and set up a receiver harmonisation/compatibility centre;

*  Broadcast Towers (similar to Lotus Tower) – Opportunities to establish and operate consolidated broadcast towers in the country;

*  Telcos- opportunity to purchase superior vacant spectrum for future fixed and mobile broadband applications.

Funding arrangements or self-financing

The current funding arrangement for digitisation of television in Sri Lanka is a ‘soft loan’ from the Japanese government, and it is tied up in ‘one bundle’ with loans for other projects. This loan is also based on the premise that the deployment of the Japanese digital television standard, Integrated Services Digital Broadcasting-Terrestrial (ISDB-T) is mandatory. As the vacant spectrum can be sold after Analogue Switch Off (ASO), the venture could also be a self-financing project, albeit with bridging finance.

Purpose of this essay

The main purpose of this article is to suggest ways of optimising the benefits of the digitisation project while retaining the support of the Japanese government. If the bulk of problems for viewers and broadcasters can be removed by making appropriate adjustments to the current plans at a minimal cost, with broadcasters becoming willing participants, the digitisation of television in Sri Lanka would no doubt be a success for all stakeholders, including the new government. Otherwise, there is an urgent need to review the bi-lateral agreement that was signed previously.

The broadcasting fraternity in Sri Lanka is fully aware that the Japanese system is not as efficient as the second generation European standard, Digital Video Broadcast-Terrestrial 2 (DVB-T2).

Understanding Digital

Simply put, digitisation of analogue vision and sound enables radio waves to carry more information within the same channel or bandwidth than in the analogue era. This allows producers of visual and aural content to be more creative than before. The technology also facilitates easy communication in both fixed and mobile environments and facilitates two-way communication more than in the analogue era. However, there are two main pitfalls that one needs to address in order to make the venture a success. They are as follows:

Cliff effect (sudden loss of signal): –

* to avoid the ‘cliff effect’ a robust signal (with higher reliability and availability at a receive location than in analogue era) is needed at the receiver to prevent momentary picture pixelation and/or sudden loss of signal; and

* it is also necessary to ensure that all television digital services reaching viewer locations are of the same signal strength to ensure equity of services and therefore must originate from ONE location such as the Lotus Tower.

* Absence of ‘graceful degradation’ and its effect on signal level – even with a degraded signal with ‘snowy pictures’, analogue signal is still watchable. It is not so with digital due to ‘cliff effect’. Therefore, there is a need to ensure that the digital coverage is the same or better than the existing watchable analogue coverage that is defined by a signal level of 43 dBuV/m in VHF Band III.

This limit was adopted for digitisation in Australia.

Deficiencies of the Japanese standard/plan

In planning to deploy the ISDB-T system in our country, everyone should aim for a cost-beneficial outcome as it is of paramount importance to all stakeholders. There are several issues in the Japanese documentation of 2014/2018, which should be addressed to suit the needs of the public/consumers, broadcasters and government. They range from policy issues at the outset, technical areas during planning and management issues during the proposed phases of ASO and Digital Switch On (DSO).

Spectrum for Digital: VHF/UHF issue

In particular, the proposal to use only a part of the available broadcast spectrum has an impact on the eventual DD income for the Government. The Japanese have deployed both VHF and UHF spectrum in Brazil, strangely not offered to Sri Lanka. In that context, it is not clear why the Japanese team has not proposed a VHF and UHF combined solution as deployed in Brazil. This was pointed out by the writer when a Japanese team, including a senior Embassy official Sato Takefumi, met him in 2017 in Colombo to discuss Lotus Tower issues (after his disclosure in an article in The Island about the Lotus tower) and digitisation in general. Their response was ‘no one asked for it’.

As it stands today in Sri Lanka, analogue television transmissions are based on frequencies using both VHF and UHF Bands, but the proposed Japanese digital conversion is not utilising the VHF Band. In particular, VHF Band III exhibits superior propagation characteristics, while contributing to lower the consumption of electricity by the transmitters. More importantly, VHF radio waves carry longer distances than UHF due to lower propagation losses, are able to travel around obstacles comparatively and therefore VHF is more suitable for wide coverage transmissions.

Currently, the VHF spectrum is occupied by three television broadcasting networks i.e. Rupavahini, ITN and TNL. These networks will lose their inherent wide coverage VHF Band advantage. They also have the additional burden of occupying a digital channel in the UHF spectrum, especially when the earmarked UHF channels for digital are almost at the bottom of the UHF Band V, where propagation losses are higher than in UHF Band IV.

ISDB-T New Coder H.265

It is a known fact that the Japanese ISDB-T standard, in payload capacity terms, is second to the second generation European Standard DVB-T2 that provides 45 Mb/s capacity. However, the Japanese standard can only carry about 1/2 of the European standard per channel at 23 Mb/s. But as the Japanese are now offering to change the content source coder to H.265, they will be able to provide HD at 1080P at a rate of 2-4 Mb/s. This change would now allow all HD TV ready broadcasters to provide True HD content at 1920 x 1080P and possibly can accommodate all television channels in Colombo. But the downside is that the receivers are going to be more complex with the new coder. This may then lead to more expensive ISDB-T receivers or STBs in Sri Lanka.

Vacant VHF Band III

The unused VHF Band III is likely to reduce the DD for the government though the Japanese strategy is to achieve some productivity by the use of single frequency networks in the UHF Band (SFNs-a technique to use the same frequency multiple times to improve spectrum productivity). However, in practice receiving of SFNs is not simplistic as the reception of SFN signals are subject to receiver complexities.

The Telecommunications Regulatory Commission (TRC) may be exclusively reserving the VHF band for future digital radio, but the same band could be co-shared with digital television without any problems. For example, Australia is co-sharing VHF Band III for both digital television and radio without any issues.

Once all analogue transmissions are switched off with the deployment of UHF band per se for digital, the unused VHF Band III spectrum, where 7 MHz bandwidth, 8 VHF Frequency channels exists, will become vacant.

This is clearly a waste of unused spectrum. Additionally, as Restacking [restack is the re-arrangement of frequencies ideally in the two bands of VHF and UHF, to maximise the spectrum productivity] is in the Japanese Plan, additional expenditure on broadcasting infrastructure is also on the cards. Where are the funds coming from?

There is no mention of new funding arrangements for Restacking of the spectrum, and it also raises questions about the STB/Receiver specifications as frequencies may need to change after Restacking.

If some broadcasters are not keen to use ISDB-T, they may canvass for the opportunity to use the vacant VHF Band for the potential deployment of DVB-T2 standard. This MUST be avoided at all costs! If this happens, there will be two digital systems in Sri Lanka. This issue, in particular, could become another potential headache for the government as it is likely to be under heavy pressure from commercial broadcasters to release the vacant VHF Band III for the more efficient DVB-T2. This issue, too, was pointed out by the writer when another Japanese team consisting of a Senior Engineer from Yacheo Engineering along with Sato Takefumi of the Japanese Embassy met him in 2017/2018.

Unless there are plans to use the vacant VHF Band III by Restacking the spectrum, this spectrum specifically allocated for broadcasting would go to waste.

Digital Signal Reliability & Availability

Unlike in the analogue domain, television signal reliability and its availability becomes crucial in digital reception. In the analogue era, television broadcasting service field strength was planned for 50% of the locations and 50% of the time at a receiving height of 10 m. But in digital this becomes 80%-95% of the locations and 90% of the time to ensure reliability and availability of the digital signal. Hence the planned field strength would need to be adjusted to ensure the required reliability and availability at a higher field strength. In Australia, field strength used was 50 dBuV/m for Band IV and 54 dBuV/m for Band V frequencies in a rural environment

However, it is not clear from the published documents of the Japanese plans 2014/2018 whether this issue had been addressed or otherwise. The signal level at 51 dBuV/m identified in the 2018 Japanese documentation is certainly not adequate for a rural grade of service in the UHF Band! It ought to be in the region of 54-74 dBuV/m in the UHF Band V. For example, the Australian Broadcasting Planning Handbook for Digital Television Broadcasting has clearly identified these requirements and provided information on how they were derived.

Duplication Parameter

The potential impact of the proposals for duplication of coverage is illustrated in the diagram. (See Figure 01)

The signal threshold of a planned analogue coverage is 50 dBuV/m for VHF Band III. However, some regional and rural viewers in Sri Lanka are currently receiving watchable analogue signals well below this value. If, as planned by the Japanese studies in 2014, the analogue coverage is converted at the planned cut-off level of 55 dBuV/m, then the majority of regional and rural viewers, who are currently watching the analogue television with no issues, will not be able to receive digital television coverage. This could potentially become a political nightmare for the new government. Therefore, the cut-off signal level, as illustrated above, should be lowered to 43 dBuV/m.

Though Single Frequency Networks (SFNs) are a solution to mitigate this difference in coverage, it is not easy to implement them at the receiver-end due to the variation in receiver profiles of Set-Top-Boxes (STBs) and complexities in receiver SFN signal detection.

The Japanese designers, while being aware of this issue, may have been heavily constrained due to the requirement for spectrum productivity. Most probably, given the limits of the available UHF spectrum for digital and the lower data efficacy of the Japanese ISDB-T standard, this higher limit of duplication may have been proposed by the designers in order to preserve some spectrum productivity.

One Network Operator for Digital

The advent of digital terrestrial television also signifies the end of individual transmission facilities for broadcasters, as several content feeds are carried on one frequency or the channel and the requirement to consolidate all transmissions at one site. A combined digital transmission service provider may, in the future, be an independent entity and the facilities may be offered to the broadcasters on a fee-levying basis, based on a pragmatic business plan. In a future digital broadcasting landscape, the broadcasters will essentially be ‘content’ providers. Perhaps, there ought to be some sort of protection provided to the existing broadcasters in the event new content providers also express a desire to use digital transmissions.

Cost to viewers and broadcasters

All consumer television sets require digital receivers to extract video and audio content from digital transmissions. Therefore, either in-built ISDB-T receivers or compatible STBs are required. For example, there are flat TVs that do not have in-built ISDB-T receivers. The cost of an STB for ISDB-T with H.265 decoders, is likely to be around US $ 50-100, depending on their complexity and economies of scale. If in the event, there is likely to be a Restack of frequencies including the VHF Band, two band STBs or receivers may be needed; one during the first phase and another after the Restack of channels with the ability to tune into the VHF Band. Additionally, at some household locations, there may also be a requirement for new receiver antenna installation to receive VHF/UHF channels. If so, this is also an additional cost to the viewer.

There is also a significant cost to the commercial television broadcasters to provide HD ready studios, Outside Broadcast (OB)/Electronic News Gathering (ENG) equipment, and content feeding arrangements. However, once the commercial television broadcasters elect to use consolidated broadcast towers, analogue era transmission costs would also disappear as their independent transmission networks are no longer needed, in a digital environment. It is noteworthy to highlight that the Japanese financial proposal for digitisation of television is primarily for Rupavahini, and limited to funding the analogue to digital transfer of Rupavahini facilities, including the provision of a True HD studio, OB unit, Transmission equipment and a Central Command centre for the proposed Digital Broadcast Network Operations (DBNO) at the Lotus Tower.

At this stage, there are no signs of any discussions with the broadcasters to develop a ‘road map’ to facilitate the smooth transition from analogue to digital of commercial channels. If Restack is to take place, there is likely to be additional costs but there is no mention of further Japanese funding for Restack of channels either.

As additional costs to the commercial television broadcasters are likely, strategic government policy initiatives to compensate for the additional capital expenditure in a highly competitive market are in order.

Way forward

It is heartening to note that the Japanese plan has now incorporated the more efficient coder in H.265 with an intention to maximise the use of limited payload capacity of an ISDB-T channel, which then will result in providing True HD transmission (1920 x 1080P) for ALL licensed television channels in Colombo.

If Japanese consultants can pay attention to the issues of using VHF Band III, changing receiving the field strength requirements to that of the ITU signal level requirements for UHF and address the duplication parameter issue, then ALL stakeholders including the government and broadcasters will no doubt look forward to the venture of digitisation of television in Sri Lanka.

Sri Lanka’s Foreign Policy amid Geopolitical Transformations: 1990-2024 – Part I

Published

on

President Reagan and Mikhail Gorbachev after signing the Intermediate Range Nuclear Forces Treaty in 1987, signalling the end of the Cold War

Sri Lanka’s survival and independence have historically depended on accurately identifying foreign policy priorities, selecting viable strategies as a small island state, and advancing them with prudence. This requires an objective assessment of the shifting geopolitical landscape through a distinctly Sri Lankan strategic lens. Consequently, foreign policy has been central to Sri Lanka’s statecraft, warranted by its pivotal location in the Indian Ocean—adjacent to South Asia yet separated by a narrow stretch of water.

Amid pivotal geopolitical transformations in motion across South Asia, in the Indian Ocean, and beyond, the formulation and implementation of Sri Lanka’s foreign policy has never been more critical to its national security. Despite the pressing need for a cohesive policy framework, Sri Lanka’s foreign policy, over the past few decades, has struggled to effectively respond to the challenges posed by shifting geopolitical dynamics. This article examines the evolution of Sri Lanka’s foreign policy and its inconsistencies amid shifting geopolitical dynamics since the end of the Cold War.

First

, the article examines geopolitical shifts in three key spaces—South Asia, the Indian Ocean, and the global arena—since the end of the Cold War, from Sri Lanka’s strategic perspective. Building on this, second, it analyses Sri Lanka’s foreign policy responses, emphasising its role as a key instrument of statecraft. Third, it explores the link between Sri Lanka’s foreign policy dilemmas during this period and the ongoing crisis of the post-colonial state. Finally, the article concludes that while geopolitical constraints persist, Sri Lanka’s ability to adopt a more proactive foreign policy depends on internal political and economic reforms that strengthen democracy and inclusivity.

Shifting South Asian Strategic Dynamics

Geopolitical concerns in South Asia—Sri Lanka’s immediate sphere—take precedence, as the country is inherently tied to the Indo-centric South Asian socio-cultural milieu. Sri Lanka’s foreign policy has long faced challenges in navigating its relationship with India, conditioned by a perceived disparity in power capabilities between the two countries. This dynamic has made the ‘India factor’ a persistent consideration in Sri Lanka’s strategic thinking. As Ivor Jennings observed in 1951, ‘India thus appears as a friendly but potentially dangerous neighbour, to whom one must be polite but a little distant’ (Jennings, 1951, 113).The importance of managing the ‘India Factor’ in Sri Lankan foreign policy has grown further with India’s advancements in military strength, economic development, and the knowledge industry, positioning it as a rising global great power on Sri Lanka’s doorstep.

India’s Strategic Rise

Over the past three decades, South Asia’s geopolitical landscape has undergone a profound transformation, driven by India’s strategic rise as a global great power. Barry Buzan (2002:2) foresees this shift within the South Asian regional system as a transition from asymmetric bipolarity to India-centric unipolarity. India’s continuous military advancements have elevated it to the fourth position in the Global Firepower (GFP) index, highlighting its formidable conventional war-making capabilities across land, sea, and air (Global Firepower, 2024). It currently lays claims to being the world’s third-largest military, the fourth-largest Air Force, and the fifth-largest Navy.

India consistently ranks among the fastest-growing major economies, often surpassing the global average. According to Forbes India, India is projected to be the world’s fifth-largest economy in 2025, with a real GDP growth rate of 6.5% (Forbes, January 10, 2025). India’s strategic ascendance is increasingly driven by its advancements in the knowledge industry. The country is actively embracing the Fourth Industrial Revolution (4IR) and emerging as the Digital Public Infrastructure (DPI) hub of South Asia. However, India’s rise has a paradoxical impact on its neighbours. On one hand, it offers them an opportunity to integrate into a rapidly expanding economic engine. On the other, it heightens concerns over India’s dominance, leaving them feeling increasingly overshadowed by the regional giant.

Despite significant geo-strategic transformations, the longstanding antagonism and strategic rivalry between India and Pakistan have persisted into the new millennium, continuing to shape South Asia’s security landscape. Born in 1947 amid mutual hostility, the two countries remained locked in a multi-dimensional conflict encompassing territorial disputes, power equilibrium, threat perceptions, accusations of interference in each other’s domestic affairs, and divergent foreign policy approaches. The acquisition of nuclear weapons by both countries in 1998 added a new dimension to their rivalry.

The SAARC process has been a notable casualty of the enduring Indo-Pakistani rivalry. Since India’s boycott of the Islamabad Summit in response to the 2016 Uri attack in Kashmir, the SAARC process has remained in limbo. Countries like Sri Lanka, which seek to maintain equally amicable relations with both India and Pakistan, often find themselves in awkward positions due to the ongoing rivalry between them. One of the key challenges for Sri Lanka’s foreign policy is maintaining strong relations with Pakistan while ensuring its ties with India remain unaffected. India now actively promotes regional cooperation bodies in South Asia, excluding Pakistan, favouring broader frameworks such as BIMSTEC. While Sri Lanka can benefit greatly from engaging with these regional initiatives, it must carefully navigate its involvement to avoid inadvertently aligning with India’s efforts to contain Pakistan. Maintaining this balance will require sharp diplomatic acumen.

India’s expansive naval strategy, especially its development of onshore naval infrastructure, has positioned Sri Lanka within its maritime sphere of influence. As part of the Maritime Infrastructure Perspective Plan (MIPP) launched in 2015 to enhance operational readiness and surveillance capabilities, India is developing an alternative nuclear submarine base for the Eastern Command under Project Varsha (Deccan Chronicle, 22.11.2016). This base is located in Rambilli village, 50 km southwest of Visakhapatnam and 1,200 km from Colombo (Chang, 2024). Additionally, INS Dega, the naval air base at Visakhapatnam, is being expanded to accommodate Vikrant’s MiG-29K and Tejas fighter aircraft.

Another key strategic development in India’s ascent that warrants serious attention in Sri Lanka’s foreign policy formulation is India’s progress in missile delivery systems (ICBMs and SLBMs) and nuclear-powered submarines. In 1998, India made it clear that its future nuclear deterrence would be based on a nuclear triad consisting of land-based Intercontinental Ballistic Missiles (ICBMs), submarine-launched ballistic missiles (SLBMs), and strategic bombers (Rehman, 2015). Since then, India has steadily advanced in this direction. The expansion of India’s missile delivery systems, including ICBMs and SLBMs, serves as a reminder that Sri Lanka exists under the strategic shadow of a major global power.

The development of India’s nuclear-powered ballistic missile submarines (SSBNs) accelerated after 2016. The first in this class, INS Arihant (S2), was commissioned in August 2016, followed by the launch of INS Arighat in November 2021. Designed for strategic deterrence, INS Arighat is equipped to carry the Sagarika K-4 submarine-launched ballistic missiles (SLBMs), with a range of 3,500 kilometers, as well as the K-5, a long-range SLBM capable of reaching 5,000 kilometers. The submarine is based at INS Varsha (Deb, 2021).

India has significantly advanced its missile delivery systems, improving both their range and precision. In 2021, it successfully tested the Agni-5, a nuclear-capable intercontinental ballistic missile with a range of 5,000 kilometers. On March 11, 2024, India joined the ranks of global powers possessing Multiple Independently Targetable Re-entry Vehicle (MIRV) technology (The Hindu, January 4, 2022). These advancements elevate the Bay of Bengal as a pivotal arena in the naval competition between India and China, carrying profound political and strategic implications for Sri Lanka, which seeks to maintain equally friendly relations with both countries.

Further, India’s remarkable strides in space research have cemented its status as a global power. A defining moment in this journey was the historic lunar landing on 23 August 2023, when Chandrayaan-3 successfully deployed two robotic marvels: the Vikram lander and its companion rover, Pragyan. They made a graceful touchdown in the Moon’s southern polar region, making India the fourth nation to achieve a successful lunar landing. This milestone has further reinforced India’s position as an emerging great power, enhancing its credentials to assert itself more confidently in South Asian, Indian Ocean, and global power dynamics.

India envisions a stable and secure South Asia as essential to its emergence as a great power in the Indian Ocean and global strategic arenas. However, it does not consider Pakistan to be a part of this stability that it seeks. Accordingly, when India launched the ‘Neighbourhood First Policy’ in 2008 to strengthen regional ties, Pakistan was excluded. India’s ‘Neighbourhood First Policy’ gained renewed momentum after 2015 under Prime Minister Narendra Modi. His approach to South Asia is embedded in a broader narrative emphasising the deep-rooted cultural, economic, and social exchanges between India and other South Asian countries over centuries. India’s promotion of heritage tourism, particularly the ‘Ramayana Trail’ in Sri Lanka, should be viewed through this strategic lens as part of its broader strategic narrative.

Evolving Indian Ocean Geo-political Dynamics

The Indian Ocean constitutes the next geopolitical frame for Sri Lanka’s foreign policy. The Indian Ocean is a huge bay bordered by the Afro-Asian landmass and Australia on three sides and the South Asian peninsula extends into the Indian Ocean basin centrally. Situated at the southern tip of South Asia, Sri Lanka extends strategically into the heart of the Indian Ocean, shaping its geopolitical significance and strategic imperatives for maintaining sovereignty. Historically, Sri Lanka has often been caught in the power struggles of extra-regional actors in the Indian Ocean, repeatedly at the expense of its independence.

Sri Lanka’s leadership at the time of independence was acutely aware of the strategic significance of the Indian Ocean for the nation’s survival. The first Prime Minister D.S. Senanayake, who was also the Minister of Defence and External Affair, stated in Parliament that: “We are in a dangerous position, because we are on one of the strategic highways of the world. The country that captures Ceylon would dominate the Indian Ocean. Nor is it only a question of protecting ourselves against invasion and air attack. If we have no imports for three months, we would starve, and we have therefore to protect our sea and air communications” (Hansard’s Parliamentary Debates, House of Representative. Vol. I, 1 December 1947, c. 444)

As naval competition between superpowers during the Cold War extended to the Indian Ocean, following the British naval withdrawal in the late 1960s, Sri Lanka, under Prime Minister Sirimavo Bandaranaike, played a key diplomatic role in keeping the region free from extra-regional naval rivalry by mobilising the countries that were members of the Non-Aligned Movement (NAM). In 1971, Sri Lanka sponsored a proposal at the UN General Assembly to establish the Indian Ocean as a Peace Zone (IOPZ). While the initiative initially gained traction, it stalled at the committee stage and ultimately lost momentum.

The maritime security architecture of the Indian Ocean entered a new phase after the end of the Cold War. The United States became the single superpower in the Indian Ocean with an ocean-wide naval presence bolstered by the fully fledged Diego Garcia base. Correspondingly, the regional strategic linkages that evolved in the context of the Cold War were eventually dismantled, giving way to new strategic relationships. Additionally, three key developments with profound implications for Sri Lanka should be noted: India’s projection of political and naval power into the deeper Indian Ocean, China’s rapid economic and military rise in the region, and the entry of other extra-regional powers into Indian Ocean politics. Although Sri Lanka adopted a broader strategic perspective and a more proactive foreign policy in the 1970s, its approach to geopolitical developments in the Indian Ocean in the post-Cold War era became increasingly shaped by domestic challenges—particularly countering the LTTE threat and addressing post-war exigencies.

India’s Expanding Naval Diplomatic Role in the Indian Ocean

Parallel to its strategic rise, India has intensified its engagement in the broader strategic landscape of the Indian Ocean with renewed vigor. This expansion extends beyond its traditional focus on the South Asian strategic theatre, reflecting a more assertive and multidimensional approach to regional security, economic connectivity, and maritime diplomacy. India’s active participation in multilateral security frameworks, infrastructure investments in critical maritime hubs and strategic alignments with major global powers signify its role in the changing naval security architecture of the Indian Ocean. India’s shifting strategic posture in the Indian Ocean is reflected in the 2015 strategy document Ensuring Secure Seas: Indian Maritime Security Strategy. It broadens the definition of India’s maritime neighbors beyond those sharing maritime boundaries to include all nations within the Indian Ocean region (Ensuring Secure Seas, p. 23).

In 2015, Indian Prime Minister Narendra Modi launched his signature Indian Ocean diplomacy initiative, Security and Growth for All in the Region (SAGAR) to foster trust and transparency, uphold international maritime norms, respect mutual interests, resolve disputes peacefully, and enhance maritime cooperation. Strategic engagement with the littoral states in the Indian Ocean region, especially Sri Lanka, the Maldives, Seychelles, and Mauritius and Madagascar has emerged as a key component of India’s Indian Ocean naval diplomacy.

The Seychelles archipelago, located approximately 600 miles east of the Diego Garcia base, holds particular significance in India’s maritime strategy. During Prime Minister Narendra Modi’s official visit to Seychelles in March 2015, India and Seychelles signed four agreements. A key strategic outcome of the visit was Seychelles’ agreement to lease Assumption Island, one of its 115 islands, to India—a move that reinforced Seychelles’ alignment with India’s broader naval diplomacy in the Indian Ocean

Similarly, Mauritius holds a central position in India’s naval diplomacy in the Indian Ocean. During Prime Minister Modi’s visit to Mauritius in March 2015, India signed a Memorandum of Understanding with Mauritius to establish a new base on North Agalega Island, a 12-kilometer-long and 1.5-kilometer-wide Island. The base is crucial for air and surface maritime patrols in the southwest Indian Ocean. It will also serve as an intelligence outpost. In September 2016, defense and security cooperation between India and Mauritius deepened alongside the signing of the ‘Comprehensive Economic Cooperation Partnership Agreement’ (CECPA).

India’s expanding strategic interests across the Indian Ocean are reflected in its growing economic, educational, and defense collaborations with Madagascar. In 2007, India established its first overseas listening post in northern Madagascar to monitor shipping activities and intercept marine communications in the Indian Ocean. This initiative provided India with a naval foothold near South Africa and key sea-lanes in the southwestern Indian Ocean. The significance of India’s defense ties with Madagascar is further highlighted by Madagascar’s participation in China’s Belt and Road Initiative (BRI). As a crucial hub along the Maritime Silk Road connecting Africa, Madagascar’s strategic importance is underscored in the broader geopolitical landscape.

Another element of India’s expanding naval diplomacy in the Indian Ocean is its participation in both unilateral and multilateral anti-piracy operations. India’s commitment to regional security was reinforced in 2008 when it established a ‘Strategic Partnership’ with Oman, securing berthing and replenishment facilities for its navy, along with a strategically significant listening post in the Western Indian Ocean. India’s naval presence in the Arabian Gulf gains additional significance amid reports of a new Chinese naval base in Djibouti and recent submarine deployments. Successful anti-piracy missions in the western Indian Ocean underscore India’s growing influence in the region’s evolving naval security architecture.

India increasingly views its vast Diaspora as a soft power tool to bolster its status as an Indian Ocean power. In June 2014, it launched the Mausam project to reinforce its cultural ties across the region, showcasing its heritage, traditions, and contributions to global arts, literature, cinema, yoga, and cuisine. This initiative complements India’s expanding naval diplomacy and strategic presence in the Indian Ocean. Over the years, it has established listening facilities, airfields, and port infrastructure in key locations such as northern Madagascar, Agaléga Island (Mauritius), and Assumption Island (Seychelles). This has led India Today to ask: “Could this mark the emergence of an Indian ‘String of Flowers’ to counter China’s ‘String of Pearls’?” (The be continued)

Exploring Sunethra Rajakarunanayake’s Visachakayo

Sunethra Rajakarunanayake’s Sinhala novel Visachakayo (published in 2023) is a thriller in its own sense due to its daring exploration of social themes that modern Sinhala writers fail to touch. To me, the novel is a mosaic that explores pressing issues that middle-class Sri Lankans go through in the 21st Century. The narrative is seen from the perspective of Akshara, a Tamil girl whom the reader first meets in an infamous ‘Visa Queue’ to get her passport to go to England.

Akshara lives with her grandmother ‘Ammamma’ and her aunt ‘Periyamma’ (the younger sister of her mother). Both Ammamma and Periyamma look after her in the absence of her mother, Chinthamani who passed away a long time ago. Akshara’s father lives in Jaffna, with the kids of the second marriage. Later, we are told that Akshara’s father had to marry the second wife due to the loss of his wife’s first husband, who was an LTTE cadre. The second marriage of men seems to be a common theme in the novel due to their commitments to the family as an act of duty and honour.

The most iconic character in the novel is Preethiraj, ‘the man with a big heart’ who functions as a father figure to the other characters in the novel. It is through Preethiraj’s memory that the reader becomes aware of sociological themes in the novel: displacement and immigration, the institution of marriage and mental health issues. Preethiraj (fondly known as Preethi) is the son of Pushpawathi, the second wife of Akshara’s grandfather. Preethi goes to Royal College, but he has to relocate to Jaffna in 1958. Preethi endures social injustice in both public and private spheres. His studious sister, a medical student, labels him as a ‘lunatic’, while his mother condemns him as the ‘odd one’.

The novel intersects between the three themes: immigration and displacement, mental health issues and the institution of marriage. Almost all the characters have to go through displacement, suffer from intricacies of love laws and marriage rules like in The God of Small Things by Arundathi Roy. The writer offers a nuanced analysis of these three themes. For example, take mental health issues. The novel portrays a spectrum of mental health issues, such as schizophrenia, psychosis, Othello Syndrome, depression, autism and even malingering. At times, the representation of such ailments is extremely sarcastic:

“Hm… Canadian citizenship is an easy solution to secure those opportunities. However, unless I am asked to intervene, I will not meddle with their affairs. The son of one of my friends was introduced to a pretty girl. They liked her, not because of her money, but because of her looks and her ability to play the piano. But later, they discovered she has schizophrenia. Now their son follows whatever she says to save the marriage. My friend says she has lost her son” (p.20).

“Those opportunities” refer to material wealth including money and property in Colombo. Here, Rajakarunanayake does not fail to capture the extreme materialism and consumerism. However, in general, her representation of human follies is extremely humane.

   The title ‘Visachakayo’ is another interesting coinage that reflects the plight of Sri Lankans who migrate to the ‘global north’ in search of greener pastures. Akshara’s friend, Subhani, who has migrated to England, explains that the term ‘Visachaya’ captures the in-between status of immigrants who are waiting for PR in a foreign country. Subhani mockingly says that they are equal to beggars who beg for visas. Subhani’s coinage and other accounts of Sri Lankan immigrants in England, the novel shows how difficult it is for an immigrant from the ‘global south’ to fight for a living in a country like England where immigrants come to resolve their financial struggles back home.

The novel is an eye-opener in many ways. First, it is an attempt to bridge the gap caused by the Sinhala-Tamil ethnic strife. It is also a cultural mosaic that captures both the joys and sorrows of Sinhala, Tamil and Burgher families in Sri Lanka. The novel also delves into mental health issues, categorically tied to marriage, a daring task even for a seasoned writer. However, Rajakarunanayake’s writing style compels the reader to adopt a more humane and empathetic approach towards individuals grappling with mental health challenges at various stages of their lives. The linguistic technique of using ‘ne’ tag at the end of sentences creates a conversational tone, making the narrative as if it is a conversation between a therapist and a patient. Her writing style also resembles that of Sri Lankan and Indian diasporic writers, a style that is used when writing about the motherland in exile, of which food becomes a critical trope in the narrative that unites the characters who live in exile.

Rajakarunanayake has done a commendable job in the representation of social issues, making this novel a must-read for anyone who is interested in researching social dynamics of contemporary Sri Lanka. It soon needs to be translated into English which will offer a unique experience to Sri Lankan English and international readers. A good book is something that affects the reader. Visachakayo has this quality, and it makes the reader revisit the past, reflect on the present and anticipate the future with hope for humanity just as Preethi does regardless of hardships he endured in the theatre of life.

A strategy for Mahaweli authority to meet future challenges amidst moves to close it down

Published

on

The potential available in lands under Mahaweli Project, which cover about one third of farming areas of the Dry Zone, could easily help the country become self-sufficient in healthy foods, provided it is managed properly. However, at present, the main focus of the Mahaweli Authority of Sri Lanka (MASL) is mainly on Operation & Maintenance of Canal network feeding the farms. Main purpose of the Mahaweli Restructuring & Rehabilitation Project (MRRP) funded by the World Bank in 2000 was to diversify that objective to cover enhancement of agriculture aspects also. System H Irrigation Systems covering about 20,000 Hectares commanded under Kalawewa Tank located in the Anuradhapura District was used as a pilot area to initiate this effort. However, only the Canal Rehabilitation component of the MRRP was attended because of the government policy at that time. Restructuring component is still awaiting to be completed. Only, a strategy called Water Quota was introduced under the MRRP to initiate the restructuring component. However, the management restructuring required addressing the agriculture component expected under MRRP is still not attended.

Propose Strategy

Total length of the canal network which needs seasonal maintenance is about 1,000 Km in a typical large-scale irrigation project such as Kalawewa. Main role of the Resident Project Managers (RPM) appointed to manage such projects should be to enhance the food production jointly with the Farmer Organizations. Therefore, the abbreviation used for RPM should be redefined as Resident Production Manager. The role of a Production Manager is not limited to maintenance of canal networks as adapted presently. In the current production phase, Irrigation projects should be perceived as a Food Producing “Factory” – where water is the main raw material. Farmers as the owners of the factory, play the role of the labour force of the factory. The Production Manager’s focus should be to maximize food production, deviating from Rice Only Mode, to cater the market needs earning profits for the farmers who are the owners of the “factory”. Canal systems within the project area which need regular maintenance are just “Belts” conveying raw materials (water) in a Typical Factory.

Required Management Shift

In order to implement the above management concept, there is a need for a paradigm shift in managing large scale irrigation projects. In the new approach, the main purpose of managing irrigation systems is to deliver water to the farm gate at the right time in the right quantity. It is a big challenge to operate a canal network about 1000 KM long feeding about 20,000 Hectare in a typical Irrigation System such as Kalawewa.

It is also very pathetic to observe that main clients of irrigation projects (farmers providing labor force) are now dying of various diseases caused by indiscriminate use of agrochemicals. Therefore, there is a need to minimize the damages caused to the ecosystems where these food production factories are located. Therefore, the management objectives should also be focused on producing multiple types of organically grown crops, profitably without polluting the soil and groundwater aquifers causing diseases like Kidney Failures.

Proposed Management Structure

Existing management staff should either be trained or new recruitments having Production Engineering background, should be made. Water should be perceived as the most limited input, which needs to be managed profitably jointly with the farming community. Each Production Manager could be allocated a Fixed Volume of water annually, and their performance could be measured in terms of $s earned for the country per Unit Volume of water, while economically upgrading a healthy lifestyle of the farmers by using climate smart agriculture.

In addition to the government salary, the production management staff should also be compensated in the form of incentives, calculated in proportion to income generated by them from their management areas. It should be a Win-Win situation for both farmers as well as officers responsible for managing the food production factory. Operation of the Main Canal to cater flexible needs of each factory is the main responsibility of the Resident Production Manager. In other countries, the term used to measure their performance is $ earned per gallon of water to the country, without damaging the ecosystem.

Recent Efforts

Mahaweli Authority introduced some of the concepts explained in this note during 2000 to 2006, under MRRP. It was done by operating the Distributary canals feeding each block as elongated Village Tanks. It was known as the Bulk Water Allocation (BWA) strategy. Recently an attempt was made to digitize the same concept, by independently arranging funds from ICTA / World Bank. In that project, called Eazy Water, a SMS communication system was introduced, so that they can order water from the Main Reservoir by sending a SMS, when they need rather; than depend on time tables decided by authorities as normally practiced.

Though the BWA was practiced successfully until 2015, the new generation of managers did not continue it beyond 2015.

Conclusion

The recent Cabinet decision to close down the MASL should prompt the MASL officers to reactivate the BWA approach again. Farmer Organisations at the distributary canal level responsible for managing canal networks covering about 400 Hectares can be registered as farmer cooperatives. For example, there are about 50 farmer cooperatives in a typical irrigation project such as Kalawewa. This transformation should be a gradual process which would take at least two years. I am sure the World Bank would definitely fund this project during the transition period because it is a continuation of the MRRP to address the restructuring component which was not attended by them in 2000 because of government policy at that time. System H could be used as a pilot demonstration area. Guidelines introduced under the MRRP could be used as tools to manage the main canal. World Bank funded Agribusiness Value Chain Support with CSIAP (Climate Smart Irrigated Agriculture Project) under the Ministry of Agriculture which is presently in progress could also provide necessary guidelines to initiate this project.
