Patient-centred care and CKDu

Some observations on the occasion of World Kidney Day
By Prof. M.W. Amarasiri de Silva
(Inaugural Fellow, International Society of Nephrology 2018, Adjunct Professor at the University of Pittsburgh, USA, and Professor Emeritus, University of Peradeniya)
Today is World Kidney Day, and this year the principal focus is on patient-centred care for people living with kidney disease. This theme highlights the increasing recognition of the need to identify and address patients’ priorities, values, and goals in order to advance the research, practice, and policy designed to improve the quality of life of people suffering from chronic kidney disease. Regardless of the type of kidney disease or the approach to treatment adopted, patients want to live well, retain their social place, maintain some semblance of normality, and have a sense of control over their health and wellbeing.
A patient-centred approach is one where the patients are treated as social individuals and enabled to take control of and improve their health. Thus, they become active participants in their care. Their biology becomes secondary in this process. Members of patients’ families and communities can continue to focus on them as people, rather than on their illness or disability. Support should concentrate on achieving the patients’ aspirations and be tailored to their needs and unique circumstances.
A patient-centred approach to health requires building public policy, creating supportive environments, facilitating community action, and developing and improving patients’ skills and knowledge of disease management. Overall, any such programme requires a complete reorientation of the treatment system. Those who work directly with patients at the District Secretariat (DS) Division level – the public health inspectors, public health nurses, nurses, hospital attendants, community workers, health educators, rural development officers, childcare officers, and others – should be directed towards a patient-centred approach, and trained in good communication skills and to address patient needs effectively. A patient-centred approach should address those with chronic disease of unknown aetiology (CKDu) within their family and community, and become an integral part of everyday life in the family and community. If CKDu sufferers are uprooted from their social setting and placed in a clinic-based environment, the treatment system becomes an artificial one with no link to the patient’s cultural milieu. Such treatment systems do not work satisfactorily.
In western societies, community health workers, working in communities, facilitate this process by assisting the medical specialists in hospitals. They visit the homes of patients and help their families to overcome problems through counselling. In Sri Lanka, such a link between the community/family and the hospital, focusing on the patient, is missing. Especially with regards to CKDu patients, establishing a connection between the community and the hospital is crucial. Such a link would help to alleviate the stigma attached to CKDu patients in the community and the neglect and isolation that many have to endure. Visits by hospital staff and paramedics to patients in their homes can improve the understanding of hospital staff about how patients live at home, what problems do they face at home and in the community. It would improve the commitment of patients towards their treatment. This would also improve their compliance with their medical regimen. A change in the treatment procedures from a hospital-based system to a patient-centred one is necessary, as the existing approach has had little impact in assisting CKDu patients in addressing their grievances and improving their quality of life, or in reducing the incidence of and death rates from the disease.
In a patient-centred approach to the treatment and care of CKDu patients, essential elements are community engagement and empowerment. Educating the patients and their families on disease risk factors and treatments is a prerequisite. In Sri Lanka, government programmes have invested in developing people’s understanding of the risk factors for CKDu but have not paid much attention to improving people’s knowledge of treatments and testing procedures. Therefore, most people in CKDu-affected areas have knowledge of the causes of CKDu, but have limited understanding of treatments. As a result, patients are not able to make an informed decision on the type of treatment that they should undergo or to discuss the subject with their medical professionals. They blindly accept (or reject) the type of treatment recommended by the doctors.
In Sri Lanka, people’s knowledge of treatments for kidney disease is fragmentary. Their knowledge of things like blood transfusion is limited and is very hospital centred. Experience in other countries shows that patients on a home therapy or haemodialysis at home were more satisfied than those with in-centre haemodialysis. In Sri Lanka, haemodialysis at home has not been promoted.
Most CKDu patients undergo harrowing experiences in their communities and at home. They report a substantial drop in their quality of life. Their illness means that they cannot draw water from the dug well to wash or use the toilets with squatting pans. They are advised to install commodes in their toilets, but most CKDu patients cannot afford to do this. Many say that they cannot cultivate their rice paddy land, so they don’t get any income from agriculture. Although they are paid Rs. 5,000 by the government each month, that is not adequate for a family of five people to live an ordinary life. As CKDu patients find it difficult to use public transport, they have to hire a vehicle at a significant cost each time they visit the clinic. In many families, children have dropped out of school because their parents cannot afford to provide for their education. About 15% of CKDu patients in the villages live alone, with, in many cases, their wives having left them and gone to the Middle East for employment. Family members say that the CKDu patients have become demanding. Many CKDu patients and their family members display signs of depression and uneasiness.
Those patients on dialysis need to attend the clinic once every three days. Many patients do not attend the clinics as required due to financial difficulties. Each visit to the clinic requires Rs. 2,000 to 3,000 for transportation, which is beyond many patients’ means, and therefore, after a few visits, they drop out of the dialysis programme. A patient told me, ‘the doctor told me that I have to get a kidney transplant. I am on the waiting list like many thousands of patients. I have no great hopes anyway. I undergo blood transfusion. I was asked to come to the clinic every third day, but I don’t have money to pay for a vehicle every time. I mortgaged my two acres of rice paddy two years ago, and the money has been spent on my treatment and food for the family’.
A patient-centred approach should highlight how to improve the quality of life of CKDu patients and families. The quality of life for patients should become the dominant preoccupation in health promotion in CKDu communities. Essential health professionals, such as health educators, public health inspectors, and public health midwives, should take the lead in educating the CKDu-affected population about the management of patients at home and in their communities. They should discuss how behavioural changes could improve health, for example identifying the adverse effects of smoking and chewing tobacco. Referring to her husband, a CKDu patient, a woman said, ‘My husband smokes a lot. He smokes a bundle of beedi a day. One bundle of beedi is Rs. 100 and contains 25 beedis. He smokes them at night, early in the morning, and at work… However much I tell him to, he doesn’t stop’. Many patients do not regularly take the medication given by the clinic or attend their appointments as scheduled.
People surveyed during the course of my research were not very aware of the difference between CKD and CKDu. Most CKDu patients identified having diabetes and high blood pressure as risk factors for CKDu. They are risk factors for CKD, and CKDu develops due to other factors in the absence of diabetes and hypertension. Most end-stage patients did not know what treatment options were available for them, and preferred to stay and die at home. Compared to affluent families in the CKDu-affected communities, the paddy farmers who own less than two acres of rice paddy are less educated and lacking in CKDu-related health knowledge.
Any community empowerment programme, focusing on CKDu patients, should discuss the basics of kidney function, CKDu testing procedures, and the management of CKDu at home and in the community.
Recommendations:
A reorientation of the hospital-centred approach to a patient-centred one. This requires training local officers at the DS Division level. A programme for this has to be identified and discussed at ministerial level with the participation of Community Based Organisations in the area, patients, carers, medical and paramedical practitioners. A sociologist/anthropologist working in the area of community empowerment and participation would also be an asset.
The introduction of home dialysis should be considered as a measure to enhance the community/family role in CKDu disease management. Home dialysis needs a cleanroom, which is hard to find in farmer households in CKDu-endemic areas. Therefore, for each Grama Niladhari Division, the government should consider building a spacious room in a central location and constructing all the facilities for patients to come and undergo dialysis. A community member should be trained to handle the procedures.
To effectively address the increasing incidence of CKDu in the epidemic regions in Sri Lanka, a well-developed intervention and a community education programme, focusing on behavioural change, should be aimed at lower socioeconomic groups.
The government should strengthen the patient-centred approach to treatment and care. Although medical education programmes in the universities prioritize medical professionals’ role in treatment, patient-centred approaches are seldom discussed. The universities should focus on CKDu-affected districts when selecting villages for students’ intervention and training on a patient-centred approach. Departments of Community Medicine should take the lead in this direction.
A programme to address depression among CKDu patients, needs to be established. DS Division level officers appointed for community work should be trained to handle the psychological issues afflicting CKDu patients. The education and counselling of end-stage kidney patients are essential as many such people have refused to undergo dialysis or kidney transplants.
The basics of kidney function and the risk factors for CKDu should be taught to school pupils in areas where CKDu is endemic.

Challenges to addressing allegations during Sri Lanka’s armed conflict

A political commentator has attributed the UK sanctions against four individuals, three of whom were top ranking Army and Navy Officers associated with Sri Lanka’s armed conflict, to the failure of successive governments to address human rights allegations, which he describes as a self-inflicted crisis. The reason for such international action is the consistent failure of governments to conduct independent and credible inquiries into allegations of war crimes; no ‘effective investigative mechanism’ has been established to examine the conduct of either the Sri Lankan military or the LTTE.
He has not elaborated on what constitutes an “effective investigative mechanism. He has an obligation and responsibility to present the framework of such a mechanism. The hard reality however is that no country, not even South Africa, has crafted an effective investigative mechanism to address post conflict issues.
INVESTIGATIVE MECHANISMS
The hallmark of a credible investigative mechanism should be unravelling the TRUTH. No country has ventured to propose how such a Mechanism should be structured and what its mandate should be. Furthermore, despite the fact that no country has succeeded in setting up a credible truth-seeking mechanism, the incumbent government continues to be committed to explore “the contours of a strong truth and reconciliation framework” undaunted by the failed experiences of others, the most prominent being South Africa’s Truth and Reconciliation Commission.
South Africa’s Truth and Reconciliation Commission is often cited as the gold standard for post conflict Mechanisms. Consequently, most titles incorporate the word “Truth” notwithstanding the fact that establishing the “Truth” was a failure not only in South Africa but also in most countries that attempted such exercises.
Citing the South African experience, Prof. G. L. Peiris states: “pride of place was given to sincere truth-telling which would overcome hatred and the primordial instinct for revenge. The vehicle for this was amnesty…… Despite the personal intervention of Mandela, former State President P. W. Botha was adamant in his refusal to appear before the Commission, which he deemed as ‘a fierce unforgiving assault’ on Afrikaaners” (The Island, 01 April, 2025). In the case of Sri Lanka too, disclosures to find the “Truth” would be all about the other party to the conflict, thus making Truth seeking an accusatory process, instead of a commitment to finding the Truth. The reluctance to engage in frank disclosure is compounded by the fear of recrimination by those affected by the Truth.
Continuing Prof. Peiris cites experiences in other countries. “Argentina, the power to grant amnesty was withheld from the Commission. In Columbia, disclosure resulted not in total exoneration, but in mitigating sentences. In Chile, prosecutions were feasible only after a prolonged interval since the dismantling of Augusta Pinochet’s dictatorship ….” (Ibid).
The mechanisms adopted by the countries cited above reflect their own social and cultural values. Therefore, Sri Lanka too has to craft mechanisms in keeping with its own civilisational values of restorative and not retributive justice for true reconciliation, as declared by President J. R, Jayewardene in San Francisco as to what the global attitude should be towards Japan at the conclusion of World War II. Since the several Presidential Commissions appointed under governments already embody records of alleged violations committed, the information in these commission reports should be the foundation of the archival records on which the edifice of reconciliation should be built.
ESTABLISHING DUE CONTEXT
The suggestion that an independent and credible inquiry be conducted into allegations of war crimes reflects a skewed understanding of the actual context in which the armed conflict in Sri Lanka occurred. Even the UNHRC has acknowledged that the provisions of “Article 3 common to the four Geneva Conventions relating to conflicts not of an international character is applicable to the situation in Sri Lanka, as stated in para. 182 of the OISL Report by the UNHRC Office. Therefore, the correct context is International Humanitarian Law with appropriate derogations of Human Rights law during an officially declared Emergency as per the ICCPR.; a fact acknowledged in the OISL report.
Consequently, the armed conflict has to conform to provisions of Additional Protocol II of 1977, because “This Protocol, which develops and supplements Article 3 common to the Geneva Conventions is the due context. There is no provision for “alleged war crimes” in the Additional Protocol. Although Sri Lanka has not formally ratified Additional Protocol II, the Protocol is today accepted by the Community of Nations as Customary Law. On the other hand, “war crimes” are listed in the Rome Statute; a Statute that Sri Lanka has NOT ratified and not recognized as part of Customary Law.
Therefore, any “investigative mechanism” has to be conducted within the context cited above, which is Additional Protocol II of 1977.
SRI LANKAN EXPERIENCE
On the other hand, why would there be a need for Sri Lanka to engage in an independent and credible inquiry into allegations, considering the following comment in Paragraph 9.4 and other Paragraphs of the Lessons Learnt and Reconciliation Commission (LLRC)?
“In evaluating the Sri Lankan experience in the context of allegations of violations of IHL (International Humanitarian Law), the Commission is satisfied that the military strategy that was adopted to secure the LTTE held areas was one that was carefully conceived in which the protection of the civilian population was given the highest priority”
9.7 “Having reached the above conclusion, it is also incumbent on the Commission to consider the question, while there is no deliberate targeting of civilians by the Security Forces, whether the action of the Security Forces of returning fire into the NFZs was excessive in the context of the Principle of Proportionality…” (Ibid)
The single most significant factor that contributed to violations was the taking of Civilians in the N Fire Zone hostage (NFZ) by the LTTE. This deliberate act where distinction between civilian and combatant was deliberately abandoned, exposed and compromised the security of the Civilians. The consequences of this single act prevent addressing whether military responses were proportionate or excessive, or whether the impact of firing at make-shift hospitals were deliberate or not, and whether limiting humanitarian aid was intentional or not. These issues are recorded and addressed in the Presidential Commission Reports such as LLRC and Paranagama. This material should be treated as archival material on which to build an effective framework to foster reconciliation.
UK SANCTIONS
Sanctions imposed by the UK government as part of an election pledge for Human Rights violations during the armed conflict is a direct act of intervention according to Article 3 of the Additional Protocol of 1977 that is the acknowledged context in which actions should be judged.
Article 3 Non-intervention states:
1 “Nothing in the Protocol shall be invoked for the purpose of affecting the sovereignty of a State or the responsibility of the government by all legislative means, to maintain or re-establish law and order in the State or to defend the national unity and territorial integrity of the State”.
2 “Nothing in the Protocol shall be invoked as a justification for intervening directly or indirectly, for any reason whatsoever, in the armed conflict or in the internal or external affairs of the High Contracting Party in the territory on which the conflict occurs”.
Targeting specific individuals associated with the armed conflict in Sri Lanka is a direct assault of intervention in the internal affairs of Sri Lanka. The UK government should be ashamed for resorting to violating International Law for the sake of fulfilling an election pledge. If Sri Lanka had issued strictures on the UK government for not taking action against any military officers responsible for the Bloody Sunday massacre where 26 unarmed civilians participating in a protest march were shot in broad daylight, Sri Lanka would, in fact be intervening in UK’s internal affairs.
CONCLUSION
The UK’s action reflects the common practice of making election pledges to garner targeted votes of ethnic diasporas. The influence of ethnic diasporas affecting the conduct of mainstream politics is becoming increasingly visible, the most recent being the Tamil Genocide Education Week Act of Ontario that was dismissed by the Supreme Court of Canada on grounds the Provincial Legislations have no jurisdiction over Federal and International Laws.
However, what should not be overlooked is that the armed conflict occurred under provisions of common Article 3 of the Geneva Conventions. This Article is developed and supplemented by Additional Protocol II of 1977. Therefore, since all Geneva Conventions are recognised as Customary Law, so should the Additional Protocol II be, because it is a development of common Article 3.
Imposing sanctions under provisions of Additional Protocol II amounts to Intervention in internal affairs of a State as stated in Article 3 of the Protocol; II cited above. Such interventions are prohibited under provisions of international law.
The need to revive independent and credible inquiries after the lapse of 16 years is unrealistic because those who were perpetrators and victims alike cannot be identified and/or located. Furthermore, the cost of disclosure because of the possibility of retribution would compromise their security. A realistic approach is to use the material recorded in the Presidential Commission Reports and treat them as archival records and use the lessons learnt from them to forge a workable framework that would foster unity and reconciliation with the survivors in all communities This is not to live in the past but to live in the here and now – the present, which incidentally, is the bedrock of Sri Lanka’s civilisational values.

The Silent Invasion: Unchecked spread of oil palm in Sri Lanka

Sri Lanka’s agricultural landscape is witnessing a silent yet profound transformation with the rapid expansion of oil palm plantations. Once introduced as a commercial crop, the oil palm (Elaeis guineensis) is now at the center of a heated debate, with environmentalists and scientists warning of its devastating ecological consequences.
Speaking to The Island research scientist Rajika Gamage, said: “The spread of oil palm in Sri Lanka is not just a concern for biodiversity, but also for water resources, soil stability, and even local economies that rely on traditional crops.”
A Brief History of Oil Palm Cultivation
Oil palm, originally from West and Central Africa, was first cultivated for commercial purposes in Java in 1948 by Dutch colonists. It reached Malaysia and Indonesia by 1910, where its lucrative potential drove large-scale plantations.
According to Gamage, in Sri Lanka, the first significant oil palm plantation was established in 1968 at Nakiyadeniya Estate by European planters, initially covering a mere 0.5 hectares. Today, oil palm cultivation is predominantly concentrated in Galle, Matara, and Kalutara districts, with smaller plantations in Colombo, Rathnapura, and Kegalle.
Over the decades, he says the commercial viability of oil palm has prompted its expansion, often at the cost of native forests and traditional agricultural lands. Government incentives and private investments have further accelerated the spread of plantations, despite growing concerns over their environmental and social impacts.
Economic Boon or Environmental Curse?
Supporters of oil palm industry argue that it is the most efficient crop for vegetable oil production, yielding more oil per hectare than any other alternative. Sri Lanka currently imports a significant amount of palm oil, and expanding local production is seen as a way to reduce dependence on imports and boost local industries. However, Gamage highlights the hidden costs: “Oil palm plantations deplete water sources, contribute to soil erosion, and threaten native flora and fauna. These are long-term damages that far outweigh the short-term economic benefits.”
One of the primary environmental concerns is the aggressive water consumption of oil palm, which leads to the depletion of underground aquifers. This is particularly evident in areas such as Kalu River and Kelani River wetlands, where native ecosystems are being severely affected. Additionally, soil degradation caused by extensive monoculture farming results in loss of fertility and increased vulnerability to landslides in hilly regions.
Furthermore, studies show that oil palm plantations disrupt the natural habitats of endemic species. “Unlike rubber and coconut, oil palm does not support Sri Lanka’s rich biodiversity. It alters the soil composition and prevents the regeneration of native plant species,” Gamage explains. The loss of forest cover also exacerbates human-wildlife conflicts, as displaced animals venture into human settlements in search of food and shelter.
A Threat to Indigenous Agriculture and Culture
Beyond environmental concerns, oil palm is also threatening traditional crops like kitul (Caryota urens) and palmyrah (Borassus flabellifer), both of which hold economic and cultural significance. “These native palms have sustained rural livelihoods for centuries,” says Gamage. “Their gradual replacement by oil palm could lead to economic instability for small-scale farmers.”
Kitul tapping, an age-old tradition in Sri Lanka, provides a source of income for thousands of families, particularly in rural areas. The syrup extracted from kitul is used in local cuisine and traditional medicine. Similarly, palmyrah has deep roots in Sri Lankan culture, particularly in the Northern and Eastern provinces, where its products contribute to food security and local industries.
The rise of oil palm plantations has led to the clearing of lands that once supported the traditional crops. With large-scale commercial investments driving oil palm expansion, small-scale farmers are finding it increasingly difficult to sustain their livelihoods. Gamage warns, “If we allow oil palm to replace our native palms, we risk losing not just biodiversity, but also a vital part of our cultural heritage.”
The Global Perspective: Lessons from Other Nations
Sri Lanka is not the first country to grapple with the consequences of oil palm expansion. Malaysia and Indonesia, the world’s leading producers of palm oil, have faced severe deforestation, biodiversity loss, and socio-economic conflicts due to unchecked plantation growth.
In Indonesia, for example, vast tracts of rainforest have been cleared for palm oil production, leading to habitat destruction for endangered species such as orangutans and Sumatran tigers. Additionally, indigenous communities have been displaced, sparking legal battles over land rights.
Malaysia has attempted to address some of these issues by introducing sustainability certifications, such as the Malaysian Sustainable Palm Oil (MSPO) standard. However, implementation challenges remain, and deforestation continues at an alarming rate.
Sri Lanka can learn valuable lessons from these experiences. Implementing strict land-use policies, promoting agroforestry practices, and ensuring transparency in plantation expansion are crucial steps in mitigating environmental damage while supporting economic development.
The Urgent Need for Action
Despite these concerns, Sri Lanka has yet to enforce strict regulations on oil palm expansion. Gamage urges authorities to intervene: “It is imperative that we implement policies to control its spread before it is too late. The unchecked expansion of oil palm will lead to irreversible environmental damage.”
To address this issue, experts suggest a multi-pronged approach:
Stronger Land-Use Policies
– The government must enforce restrictions on oil palm cultivation in ecologically sensitive areas, such as wetlands and forest reserves.
Reforestation and Rehabilitation
– Efforts should be made to restore degraded lands by reintroducing native tree species and promoting sustainable agroforestry.
Supporting Traditional Agriculture
– Incentives should be provided to farmers growing traditional crops like kitul and palmyrah, ensuring that these industries remain viable.
Public Awareness and Education
– Raising awareness among local communities about the environmental and social impacts of oil palm can empower them to make informed decisions about land use.
Sustainable Alternatives
– Encouraging research into alternative vegetable oil sources, such as coconut oil, which has long been a staple in Sri Lankan agriculture, could reduce reliance on palm oil.
As Sri Lanka stands at a crossroads, the decisions made today will determine the country’s ecological and agricultural future. While the economic benefits of oil palm are undeniable, its long-term environmental and social costs cannot be ignored. The challenge now is to strike a balance between economic growth and environmental sustainability before the damage becomes irreversible.
In conclusion Gamage said, “We must act now. If we allow oil palm to spread unchecked, future generations will bear the cost of our inaction.”
Sri Lanka has the opportunity to take a different path—one that prioritises biodiversity conservation, sustainable agriculture, and the well-being of local communities. The time for decisive action is now.

A plea for establishing a transboundary Blue-Green Biosphere Reserve in Gulf of Mannar and Palk Bay

Blue-green land and waterscapes act as ecological corridors across land and water in creating an ecological continuity in order to protect and restore the habitats of native and naturalised species.
In addition, these ecological corridors also help to conserve and improve the habitats of migratory species, as well. One of the main objectives of establishing blue-green land-waterscapes is to reconcile increasing local/regional development and human livelihood challenges in a sustainable manner while, at the same time, safeguard biodiversity and their habitats/ecosystems, as far as possible.
While green landscapes are natural and semi-natural terrestrial vegetation types like natural forests and grasslands, blue waterscapes are aquatic or semi-aquatic vegetation types such as seagrass meadows, mangroves and coastal and other wetlands. These vegetated coastal ecosystems known as ‘blue carbon’ ecosystems are some of the most productive on Earth and located at the interfaces among terrestrial, freshwater and marine environments. They provide us with essential ecosystem services, such as serving as a buffer in coastal protection from storms and erosion, spawning grounds for fish, filtering pollutants and contaminants from coastal waters thus improving coastal water quality and contributing to all important food security.
In addition, they capture and store “blue” carbon from the atmosphere and oceans at significantly higher rates per unit area than tropical forests (Figure 1) and hence act as effective carbon sinks. By storing carbon, these ecosystems help to reduce the amount of greenhouse gas in the atmosphere, thus contributing significantly to mitigate the effects of climate change.

Figure 1: Carbon storage in different vegetation types (Source – What Is Blue Carbon and Why Does It Matter? – Sustainable Travel International)
.Blue-green Carbon Markets
The recognition of blue carbon (BC) ecosystems (primarily mangroves, seagrasses and tidal marshes) as an effective natural climate solution paved the way for their inclusion within carbon markets. Blue carbon is the marine analog of green carbon, which refers to carbon captured by terrestrial (i.e., land-based) plants. The blue-green carbon market involves buying and selling carbon credits from projects that protect and restore coastal and marine ecosystems (blue carbon) and terrestrial ecosystems (green carbon). Since Blue Carbon ecosystems have higher carbon sequestration (capture and store) potential compared to their terrestrial counterparts, blue Carbon credits are worth over two times more than green carbon credits. They offer opportunities for commercial enterprises to offset carbon emissions and in turn support climate action.
Blue Carbon projects are expected to grow twofold in the near future. With the recent surge in international partnerships and funding, there is immense growth potential for the blue carbon market. However, it is critically important to look beyond the value of the carbon sequestered to ensure the rights and needs of local communities that are central to any attempt to mitigate climate change using a blue and green carbon project.
Blue Carbon projects can serve as grassroot hubs for sustainable development by developing nature-based solutions in these ecosystems thus contributing to both climate change mitigation and adaptation. Globally, numerous policies, coastal management strategies, and tools designed for conserving and restoring coastal ecosystems have been developed and implemented. Policies and finance mechanisms being developed for climate change mitigation may offer an additional route for effective coastal management. The International Blue Carbon Initiative, for example, is a coordinated, global program focused on conserving and restoring coastal ecosystems for the climate, biodiversity and human wellbeing.
Until recently, most of these opportunities focus on carbon found in the above ground vegetative biomass and do not account for the carbon in the soil. On the other hand, blue carbon, in particular has the potential for immense growth in carbon capture economics in the near future and can provide significant socioeconomic and environmental benefits. Consequently, blue -green carbon habitats in the Gulf of Mannar – Palk Bay region represent invaluable assets in climate change mitigation and coastal ecosystem conservation and sustainable development.
Gulf of Mannar and Palk Bay Trans-boundary Region
The Gulf of Mannar and Palk Bay region form a transboundary area within the waters of southeastern India and northwestern Sri Lanka. This region supports dense seagrass meadows having a high level of marine biodiversity including marine mammals such as dugong. Sea turtles are frequent visitors to the gulf while sharks, dolphins, sperm and baleen whales too, have been reported from this area. The Mannar region is recognized as an Important Marine Mammal Area (IMMA) of the world by IUCN (Figure 2) and also an Important Bird Area by Birdlife International. This region as a whole is a store house of unique biological wealth of global significance and as such is considered as one of the world’s richest regions from a marine biodiversity perspective.

Figure 2. Gulf of Mannar and Palk Bay IMMA (Source – IUCN Joint SSC/WCPA Marine Mammal Protected Areas Task Force, 2022 IUCN-MMPATF (2022)
Gulf of Mannar Biosphere Reserve – India
India has already declared a part of this region as the UNESCO Gulf of Mannar Biosphere Reserve covering an area of 10,500 km2 of ocean with 21 islands and the adjoining coastline. The islets and coastal buffer zone include beaches, estuaries, and tropical dry broadleaf forests, while the surrounding seascape of the Marine National Park (established in 1986) and a 10 km strip of the coastal landscape that include seaweed communities, seagrass communities, coral reefs, salt marshes and mangrove forests form the coastal and marine component of the biosphere reserve on the Indian side of the Gulf of Mannar.
Sri Lankan ‘Proposed’ Biosphere Reserve
On the Sri Lankan side of the Palk Bay there is a semi-enclosed shallow water body between the southeast coast of India and Sri Lanka, with a water depth maximum of 13 m. To the south, a chain of low islands and reefs known as Adam’s Bridge or Rama Setu (Rama’s Bridge), separates Palk Bay from the Gulf of Mannar. The Palk Bay leads to Palk Strait (Figure 3). Palk Bay is one of the major sinks for sediments along with the Gulf of Mannar. Sediments discharged by rivers and transported by the surf currents as littoral drift settle in this sink.
On the Sri Lankan side of the Palk Bay, studies are being conducted by the Dugong and Seagrass Conservation Project to establish an additional 10,000 hectares of Marine Protected Area to support the conservation of dugongs and their seagrass habitat in the Gulf of Mannar and Palk Bay. This project will involve the preparation of a multiple-community-based management plan in conjunction with government, fishing communities and the tourism industry.
With this valuable information emerging from projects of this nature, Sri Lanka has real opportunities to create a large marine protected area in the Gulf of Mannar and Palk Bay region and eventually merging them together with the Gulf of Mannar Biosphere Reserve of India to form a trans-boundary biosphere Reserve.
Terrestrial cum Marine Spatial Plan for the Gulf of Mannar and Palk Bay Region
Therefore, an excellent opportunity awaits both the Governments of Sri Lanka and India to collaborate in preparing of a terrestrial and marine spatial plan for this region, a prerequisite before going further on designing and implementing large scale development plans in establishing wind energy farms, mineral sand extraction, fishing industry, oil exploration and tourism development.
Coastal and Marine Spatial Planning (CMSP) is an integrated, place-based approach for allocating coastal and marine resources and space, while protecting the ecosystems that provide these vital resources.
On the Indian side, the Gulf of Mannar Biosphere reserve is well established and functional. On the Sri Lankan side, already there are three DWLC managed protected areas i) Adam’s Bridge Marine National Park (# 29 in the map – 18,990 ha declared in 2015), ii) Vedithalathiv Nature Reserve (# 35 -29,180 ha declared in 2016) and iii) Vankalai Sanctuary ( # 97 -4839 ha declared in 2008) (Figure 4) which can serve as the core zone of the Sri Lankan counterpart of a trans-boundary biosphere reserve. Due to the integrated nature of shallow wetland and terrestrial coastal habitats, Vankalai Sanctuary, in particular is highly productive, supporting high ecosystem and species diversity.

Figure 4: Protected Areas in Norther Sri Lanka Managed by the Department of Wildlife Conservation Source: DWLC
This site provides excellent feeding and living habitats for a large number of water bird species, including annual migrants, which also use this area on arrival and during their exit from Sri Lanka.
Having several coastal and marine protected areas already within the Sri Lankan territory provide an excellent opportunity to establish the Gulf of Mannar – Palk Bay blue-green Biosphere Reserve (Sri Lanka) initially and eventually to join up seamlessly with the already established Gulf of Mannar Biosphere Reserve on the Indian side to create a trans-boundary blue-green biosphere reserve.
This makes perfect sense because unlike sedentary plant species, mobile animal and plant groups (phytoplankton, in particular) do not respect human demarcated territorial boundaries. The provision of a common and unhindered protected coastal and marine passage for their customary movement for food and raising young is therefore of crucial importance in conservation management. Scientific evidence-based selection of additional areas, if necessary and their respective boundaries are best be determined in consultation with expert groups on marine mammals and reptiles, birds, fish, coastal vegetation conservation, sociology and industrial development from both sides of the divide.
Proper spatial planning needs to be done before large-scale development plans are designed and implemented in order to avoid conflicts of interest leading to inordinate delays and teething problems in project initiation. As a priority, the protected blue-green core and buffer regions need to be demarcated for their conservation. This could best be done in this narrow passage of land and water between Sri Lanka and India
( Palk Strait & Gulf of Mannar) by preparing a marine and terrestrial spatial plan along the UNESCO Man and Biosphere conceptual guidelines differentiating core, buffer and transition zones. While the protected areas in the core and buffer zone provide all important ecosystem services that would also serve as breeding ground for fish, crustaceans, marine reptiles, birds and mammals thereby provisioning sustainable industries to be developed in the surrounding transition areas demarcated in the joint spatial plan.
In addition, the Satoyama Global Initiative established by the Japanese at UNESCO as a global effort in 2009 to realise ‘societies in harmony with nature’ in which – Satoumi – specifically referring to the management of socio-ecological production landscapes in marine and coastal regions, is also a good model to be considered for conservation of biodiversity and co-existence between humans and nature.
Final Plea
In order to take this proposal forward from the Sri Lankan side, a number of useful baseline reports are already available including, but not limited to, the following: i. Biodiversity Profile of the Mannar District (CEJ & USAID 2022), ii. The Gulf of Mannar and its surroundings (IUCN 2012), iii) Atlas of Mangroves, Salt Marshes and Sand Dunes of the Coastal Area from Malwathu Oya to Pooneryn in the Northwestern Coastal Region, Sri Lanka (Ecological Association of Sri Lanka, Peradeniya, Sri Lanka, 2020). iv. Integrated Strategic Environment Assessment of the Northern Province of Sri Lanka (CEA 2014).
If this proposal to establish a Trans-boundary Blue-Green Biosphere Reserve in the Gulf of Mannar and Palk Bay is acceptable in principle to the Governments of Sri Lanka and India, it would be ideal if the Man and the Biosphere (MAB) program UNESCO which is an intergovernmental scientific program whose mission is to establish a scientific basis for enhancing the relationship between people and their environments to partner with the relevant Government and non-governmental agencies in both countries in making it a reality. This proposed concept has all the necessary elements for developing a unique sustainable conservation cum industrial development strategy via nature-based solutions while at the same time contributing to both climate change mitigation and adaptation.
