Dams indispensable but not without adverse impacts

Published

Human civilization began along rivers in the world over, as water is an essential natural resource for people. These early river valley civilizations include the Indus valley, the ancient Egypt near the Nile river, the Mesopotamia civilization along the Tigris and Euphrates rivers, and the Chinese civilization along the Yellow river. Later on, with the increase in population and technological advancements thousands of dams have been built to meet the water needs during dry periods by regulating river flows.

Today, according to estimates there are 59,071 large dams all over the world with a total storage of 16,201 Km3 according to registered data of International Commission on Large Dams (ICOLD). A dam is categorised as large if the height is greater than 15m. A dam of height 5-15 m is also considered as a large dam if its storage capacity is more than 3 MCM. Accordingly, Sri Lanka has around 80 large dams, 270 medium dams and over 10,000 small dams.

Dam types concrete, earthen, rockfill and masonry. This marvelous engineering innovation has been very useful to humanity as it provides a wide range of social, environmental and economic benefits. Providing water for domestic use, agriculture, hydropower generation, and flood mitigation are some of the main functions of dams. However, these manmade structures are not without significant impact on the environment and society. Knowing these impacts are useful in mitigating them for the ecological sustainability and social wellbeing of a country. Although the impacts of large dams are studied extensively, those of small dams are often neglected. Following are some major and quantifiable impacts of dams.

 

Siltation behind the dam

A dam greatly alters the morphological processes of rivers and streams crossed by the dam. River water naturally transport the soil eroded in the upper watersheds by rain as sediment materials up to sea. When a dam is built across a river this sediment transportation process is completely blocked. This makes the river section downstream to the reservoir sediment-hungry and river bed erosion is the result. Thus, deepened river bed cause the ground water table to decrease. The result is either a decrease in water availability or a complete drying up of nearby domestic or agro wells. These issues are further exacerbated by sand mining in rivers.

The formation of meandering river sections and oxbow lakes occur downstream many large dams in Sri Lanka due to lack of downstream sediment transport. In low lying agricultural areas, this change of river course has become a worrying issue for land owners. Further, bridge foundations in the river are exposed due to bed erosion threatening their stability. On the other hand, deficiency in sediment transport to the sea causes beaches to vanish and result in coastal erosion.

 

Increased flood risks

Most of the time reservoirs are considered flood mitigation structures. However, during continuous rains the emergency flood gates of the reservoirs are opened for their own safety. If the downstream part of the reservoir is also receiving high rainfalls the opening of flood gates would create excessive floods due to above – normal – flow capacity in the river endangering people and property in a far worse manner.

 

Reduction of downstream river flow

Reduced river flows increase the salinity level of river water closer to coastal areas impacting drinking water extractions. This has to be overcome by the construction of costly structures such as salinity barriers across rivers. The salinity intrusion can also contaminate ground water aquifers.

Dams regulate flood waters and as a consequence flood plain characteristics are altered. Generally, the soil eroded by the rain is the topmost soil layer of the river’s watershed and it is rich in nutrients. Hence, floodplains will be deprived of such nutrients as long as floodplains are not inundated by flood waters affecting agricultural activities carried out in flood plain areas. The lack of nutrient rich riverine sediments alters the ecologies of river deltas, estuaries, coastal wetlands and marine environments as well.

Block of passage for migratory animals

Migratory animals, especially fish travel along the river to upstream areas for breeding. On the other hand, the species in the food chain that depend on these migratory animals are negatively impacted when their passage is blocked by a dam.

 

Land inundation

With the construction of a dam a large area is inundated. For instance, the inundation area due to the construction of Senanayake Samudra, the largest reservoir in Sri Lanka by volume, is around 7,689 hectares. Not only bare lands, sometimes, inundation of townships, wetlands, forest and agriculture areas are also possible if permitted by proper environmental assessment processes.

 

Production of greenhouse gases

Today, the world is gravely concerned about climate change, which is known to be a consequence of global warming due to increasing greenhouse gases in the atmosphere. Often, carbon dioxide emissions from the combustion of fossil fuels are considered the major contributors for global warming. Yet, reservoirs also contribute to greenhouse gas emissions by releasing methane which is a high potential greenhouse gas. Methane is produced in reservoir beds from the decomposition of the plant materials primarily inundated after the reservoir construction.

 

Social Impacts

Dams have caused displacement of a huge number of people around the world as an adverse impact due to inundation of public properties. Most of the major dams in Sri Lanka were constructed many decades ago without facing any severe resettlement issues, whereas future dam construction works would not be so, due to urbanisation and increased population density. Further, dam construction has resulted in conflicts of water sharing specially in transboundary river basins. Being a small country, Sri Lanka is fortunate not to have such conflicts except for the Mahaweli Ganga, where minor conflicts are on the verge with ongoing developments. Loss of cultural heritage assets is another issue which could be more sensitive to people.

 

Dam failure risks

If a dam failed, it would be a huge disaster to people living close by and their properties. Dam failures could occur due to myriad reasons. Overtopping, piping, slope stability and settlement are the common modes of failure, though at times, exact reason is unknown.

In January 1986, Sri Lanka experienced the breach of the Kantalai dam in the Eastern Province. The disaster resulted in 127 deaths and affected 10,864 residents. The number of houses destroyed was 1,200, besides significant damage to agriculture and infrastructure in the area. Apart from that, massive floods in December 1957 caused failure of 35 large dams, 53 medium dams and 1500 small dams in the country within few days. The Banqiao dam failure of China, in 1975, is considered to be the deadliest of its kind ever. It destroyed 171,000 lives and displaced millions of people.

 

Final remarks

It is not wise to assume that all engineering innovations are sound and safe. The way science and technology evolved throughout the history of mankind has posed many threats to the sustainability of the world. Hence, enhancing the positive impacts of such technological creations and taking action to mitigate the negative impacts to the best possible level are the responsibilities of those who are involved in these endeavours.

Most Venerable Kotugoda Dhammavasa Uttareethara Maha Nayaka Thera turns 88

Published

on

It was in the year 1803 that there was a renaissance within the Maha Sangha (the Great Community of Buddhist Monks) in Sri Lanka thereby adding a fresh chapter to the history of the Buddha Sasana in Sri Lanka. This was when the Most Venerable Welitara Sri Gnanawimala Thera, the Great Prelate received the Upasampada or the Higher Ordination in Burma, returned to Sri Lanka and established the Sri Lanka Amarapura Nikaya. (The name of this monk is embellished with traditional appellations such as Bodhisattva Gunopetha or being imbued with the qualities of a Bodhisattva or Buddha-Aspirant, and Preacher to King and Emperor.)

Thus the Amarapura Nikaya, which began with this Most Venerable Thera, later spread itself very rapidly down five generations of the Sangha spanning the entire Island. These generations of the Sangha organized themselves into 22 Nikayas. This was with the blessings of each of the Mahanayakas. They also preserved the identity of each such Nikaya.

In Sri Lanka, Amarapura Maha Sangha Sabha was formed in 1952 with the concurrence of 15 of these subsidiary Nikayas. Presidents of the Amarapura Maha Sangha Sabha have been;

1. the Most Venerable Prelate Beruwela Siri Nivasa Thera

2. the Most Venerable Mapalane Pannalankara Maha Nayaka,

3. the Most Venerable Uddammita Dhammarakhita Maha Nayaka,

4. the Most Venerable Balangoda Ananda Maithri Maha Nayaka

5. the Most Venerable Madihe Pannaseeha Maha Nayaka.

In the year 1962 all 22 Sub-Nikayas came together to form a more organized and properly constituted Sri Lanka Amarapura Maha Sangha Sabha. It was the Most Venerable Agga Maha Panditha Balangoda Ananda Maithri Thera who was installed as President and has been succeeded by;

1. the Most Venerable Dhammavansha Thera,

2. the Most Venerable Madihe Pannaseeha,

3. the Most Venerable Ahungalla Wimalanandi,

4. the Most Venerable Kandegedara Sumanavansha,

5. the Most Venerable Boyagama Wimalasiri,

6. the Most Venerable Kotugoda Dhammavasa and

7. the Most Venerable Dodampahala Chandrasiri.

The Most Venerable Chief Prelate Ganthune Assaji Thera is the current chair.

In terms of the Constitution approved in 1992, an Office of Supreme Prelate (Uttareethara Mahanayaka) was created, and the first to hold this office was the Most Venerable Madihe Pannaseeha Mahanayaka Thera who was succeeded by Most Venerable Davuldena Gnaneesara Thera. After his demise the Most Venerable Kotugoda Dhammavasa Thera, who turns eighty-eight today assumed and continues to be the Uttareethara Mahanayaka.

He was born on 26th January 1933 and ordained as a monk with the permission of his parents, on 17th August 1948. He received his Higher Ordination on 10th July 1954 at the Udakkukhepa Seemamalakaya set up on the River named the Kalu Ganga in Kalutara.

He had his training and primary instruction in the Buddha Dhamma from his Venerable Preceptors, later entered the Paramadhamma Chetiya Pirivena for his education. It was at the Maha Pirivena in Maligakanda where he received his Higher Education in three languages, under the shadow and tutelage of the Most Venerable Pandita Baddegama Piyaratana Thera.

With the demise of his preceptor, Dhammavasa Thera became the Prelate of the Dharmapala-arama Viharaya in Mount Lavinia. By this time he had already become very popular by broadcasting and delivering sermons in temples and in private homes, contributing to articles disseminating the Dhamma, and articles on topical subjects through the full-moon day publication entitled “Budusarana”, then to daily newspapers, and to the Vesak Annuals published by M D Gunasena & Co., Dinamina etc.

The Thera was also engaged in social welfare activities of the area by setting up Children’s and Young Persons’ Societies within the Vihara.

With the passage of time and the demise of remarkably eloquent monks such as the Most Venerable Narada Thera, Prelate of the Vajira-aramaya, Heenatiyana Dhammaloka, Kotikawatte Saddhatissa, Pitakotte Somananda, Kalukondayawe Pannasekera and other such classic preachers, Kotugoda Dhammavasa Thera stands out as a prime orator among those who came to the limelight after the days of the erudite monks of yesteryear.

Owing to the ceaseless invitations to deliver sermons extended to our Venerable Thera he travelled to various regions of the Island, yet fulfilling all his duties pertaining to his own Nikaya and to the work of the Sangha Sabha neglecting nothing whatever. With all this he continued to participate in the discharge of the infinite services expected of all erstwhile office bearers of the Sangha Sabha.

Our respected Thera was gradually chosen to hold various posts within the Amarapura Nikaya. Some such are his appointment in 1970 as an ordained member of the Working Committee and to the Post of Honorary Prelate (Maha Nayaka); in 1981 as the Chief Ecclesiastical Sangha Nayaka; and in 1990 as the Deputy Chief (Anunayaka) of the Amarapura Nikaya. At the same time it is because of his quality of being industrious that he was elected the Secretary (Lekhakadhikari).

The Venerable Anunayaka Thera who served the Maha Sangha Sabha of the Sri Lanka Amarapura Nikaya with great dedication, in order to ensure its unity and advancement, was in 1980 appointed its Co-Secretary (Sama Lekhakadhikari) and in 1992 as its Chief Secretary (Maha Lekhakadhikari) It is only appropriate to place on record that during this period of about fifteen years he performed a very special quality of service to the Sasana by updating the Amarapura Sangha Sabha; by setting up a Kathikavata (Ecclesiastical Edict) for the Amarapura Nikaya (whereby ‘rules governing the discipline and conduct of Buddhist monks including matters related to the settlement of disputes’ together with a Sanghadhikarana Panatha (i.e. an Ecclesiastical Act) were drafted and approved; and finally by drafting a strong, formal Constitution and obtaining approval for same.

It was on 17th December 2016 that the Venerable Kotugoda Dhammavasa Anunayaka Thera became the Mahanayaka of the Amarapura Nikaya, and that on a proposal made by none other than the Most Venerable Agga-maha-panditha Ambalangoda Sumangala Maha Nayaka Thera who, at the time, was himself the incumbent.

On 3rd October 2008 the Venerable Kotugoda Dhammavasa Maha Nayaka Thera was appointed to the post of Chairman, and it was on 26th May 2017 that he was elected Uttareethara Maha Nayaka or Supreme Maha Nayaka, which is the highest position within the Sri Lanka Amarapura Nikaya.

He has visited many countries in Asia and Europe disseminating the Dhamma and participating in Conferences thereby earning great international fame. Meanwhile he also serves as the incumbent monk of the Sri Lanka-aramaya in Myanmar and of the Charumathie Viharaya in Nepal.

In the matters of national and religious issues in the country he expresses his views in such a calm and collected manner that he has earned the respect of the Supreme Maha Nayaka Theras of other Nikayas and politicians both in power and in the Opposition and of intellectuals.

He has been honored with the title of “Agga Maha Panditha” by the Government of Myanmar. Although other honorary awards were conferred upon him by foreign countries and foreign institutions he does not use them, entirely because of his humble disposition.

At the end of and exposition of the Dhamma (a Dharma Desana) at Temple Trees His Excellency Mahinda Rajapaksa (who was then the incumbent President of the country) made an offering to him of about 14 perches of land in Wellawatte. Upon this land stands today, the “Office of the Sangha Sabha of the Amarapura Maha Nikaya”, a three-storied building replete with all conceivable facilities. It is a matter of great joy to us that in honour of the Most Venerable Kotugoda Dhammavasa Maha Nayaka Thera it was possible for us to make an offering of this building to the Buddha Sasana, on the 15th of August 2020.

We offer merit to His Excellency the President and the Honourable Prime Minister who are today attending to each and every need of our Supreme Maha Nayaka Thera in a spirit of extending infinite regard and respect to him, in appreciation of the national and religious service the Maha Thera has rendered.

Let us also gratefully place on record that the Honourable Sajit Premadasa, Leader of the Opposition, has provided an elevator as an offering to facilitate the caring for our Mahanayaka Thera.

I also wish to thank the Doctors, the Staff of the Nawaloka Hospital, Members of the Nikaya-abhivrudhi Dayaka Sabha (Organization for the Advancement of the Nikaya) and the Dayaka Sabha of the Mahanayaka’s Vihara and who are all providing medical care.

Arrangements were made by the Dayaka Sabha and the student monks to offer alms to the Sangha to mark the birthday of our Thera when he reached the age of 88, on 26th January 2021.

On 21st January 2021 at 7.00 p.m. a Bodhi Pooja was organized by the Amarapura Nikaya-abhivruddi Dayaka Sabha at the historic Kalutara Bodhi to invoke blessings upon our Supreme Maha Thera.

May the Supreme Maha Nayaka Agga Maha Panditha Kotugoda Dhammavasa Maha Nahimi live a life free from sickness and sorrow.

Govt.’s choice is dialogue over confrontation

Published

on

By Jehan Perera

Preparing for the forthcoming UN Human Rights Council cannot be easy for a government elected on a nationalist platform that was very critical of international intervention. When the government declared its intention to withdraw from Sri Lanka’s co-sponsorship of the October 2015 resolution No. 30/1 last February, it may have been hoping that this would be the end of the matter. However, this is not to be. The UN Human Rights High Commissioner’s report that will be taken up at the forthcoming UNHRC session in March contains a slate of proposals that are severely punitive in nature and will need to be mitigated. These include targeted economic sanctions, travel bans and even the involvement of the International Criminal Court.

Since UN Secretary General Ban Ki-Moon’s visit in May 2009 just a few days after the three-decade long war came to its bloody termination, Sri Lanka has been a regular part of the UNHRC’s formal discussion and sometimes even taking the centre stage. Three resolutions were passed on Sri Lanka under acrimonious circumstances, with Sri Lanka winning the very first one, but losing the next two. As the country became internationally known for its opposition to revisiting the past, sanctions and hostile propaganda against it began to mount. It was only after the then Sri Lankan government in 2015 agreed to co-sponsor a fresh resolution did the clouds begin to dispel.

Clearly in preparation for the forthcoming UNHRC session in Geneva in March, the government has finally delivered on a promise it made a year ago at the same venue. In February 2020 Foreign Minister Dinesh Gunawardena sought to prepare the ground for Sri Lanka’s withdrawal from co-sponsorship of UN Human Rights Council resolution No 30/1 of 2015. His speech in Geneva highlighted two important issues. The first, and most important to Sri Lanka’s future, was that the government did not wish to break its relationships with the UN system and its mechanisms. He said, “Sri Lanka will continue to remain engaged with, and seek as required, the assistance of the UN and its agencies including the regular human rights mandates/bodies and mechanisms in capacity building and technical assistance, in keeping with domestic priorities and policies.”

Second, the Foreign Minister concluding his speech at the UNHRC session in Geneva saying “No one has the well-being of the multi-ethnic, multi-lingual, multi-religious and multi-cultural people of Sri Lanka closer to their heart, than the Government of Sri Lanka. It is this motivation that guides our commitment and resolve to move towards comprehensive reconciliation and an era of stable peace and prosperity for our people.” On that occasion the government pledged to set up a commission of inquiry to inquire into the findings of previous commissions of inquiry. The government’s action of appointing a sitting Supreme Court judge as the chairperson of a three-member presidential commission of inquiry into the findings and recommendations of earlier commissions and official bodies can be seen as the start point of its response to the UNHRC.

 

 

NEGATIVE RESPONSE

 

The government’s setting up of a Commission of Inquiry has yet to find a positive response from the international and national human rights community and may not find it at all. The national legal commentator Kishali Pinto Jayawardene has written that “the tasks encompassed within its mandate have already been performed by the Lessons Learnt and Reconciliation Commission (LLRC, 2011) under the term of this President’s brother, himself the country’s Executive President at the time, Mahinda Rajapaksa.” Amnesty International has stated that “Sri Lanka has a litany of such failed COIs that Amnesty International has extensively documented.” It goes on to quote from the UN High Commissioner for Human Rights that “Domestic processes have consistently failed to deliver accountability in the past and I am not convinced the appointment of yet another Commission of Inquiry will advance this agenda. As a result, victims remain denied justice and Sri Lankans from all communities have no guarantee that past patterns of human rights violations will not recur.”

It appears that the government intends its appointment of the COI to meet the demand for accountability in regard to past human rights violations. Its mandate includes to “Find out whether preceding Commissions of Inquiry and Committees which have been appointed to investigate into human rights violations, have revealed any human rights violations, serious violations of the international humanitarian law and other such serious offences.” In the past the government has not been prepared to accept that such violations took place in a way that is deserving of so much of international scrutiny. Time and again the point has been made in Sri Lanka that there are no clean wars fought anywhere in the world.

International organisations that stands for the principles of international human rights will necessarily be acting according to their mandates. These include seeking the intervention of international judicial mechanisms or seeking to promote hybrid international and national joint mechanisms within countries in which the legal structures have not been successful in ensuring justice. The latter was on the cards in regard to Resolution 30/1 from which the government withdrew its co-sponsorship. The previous government leaders who agreed to this resolution had to publicly deny any such intention in view of overwhelming political and public opposition to such a hybrid mechanism. The present government has made it clear that it will not accept international or hybrid mechanisms.

 

 

SEQUENTIAL IMPLEMENATION

 

In the preamble to the establishment of the COI the government has made some very constructive statements that open up the space for dialogue on issues of accountability, human rights and reconciliation. It states that “the policy of the Government of Sri Lanka is to continue to work with the United Nations and its Agencies to achieve accountability and human resource development for achieving sustainable peace and reconciliation, even though Sri Lanka withdrew from the co-sponsorship of the aforesaid resolutions” and further goes on to say that “the Government of Sri Lanka is committed to ensure that, other issues remain to be resolved through democratic and legal processes and to make institutional reforms where necessary to ensure justice and reconciliation.”

As the representative of a sovereign state, the government cannot be compelled to either accept international mechanisms or to prosecute those it does not wish to prosecute. At the same time its willingness to discuss the issues of accountability, justice and reconciliation as outlined in the preamble can be considered positively. The concept of transitional justice on which Resolution No 30/1 was built consists of the four pillars of truth, accountability, reparations and institutional reform. There is international debate on whether these four pillars should be implemented simultaneously or whether it is acceptable that they be implemented sequentially depending on the country context.

The government has already commenced the reparations process by establishing the Office for Reparations and to allocate a monthly sum of Rs 6000 to all those who have obtained Certificates of Absence (of their relatives) from the Office of Missing Persons. This process of compensation can be speeded up, widened and improved. It is also reported that the government is willing to consider the plight of suspected members of the LTTE who have been in detention without trial, and in some cases without even being indicted, for more than 10 years. The sooner action is taken the better. The government can also seek the assistance of the international community, and India in particular, to develop the war affected parts of the country on the lines of the Marshall Plan that the United States utilized to rebuild war destroyed parts of Europe. Member countries of the UNHRC need to be convinced that the government’s actions will take forward the national reconciliation process to vote to close the chapter on UNHRC resolution 30/1 in March 2021.
