NEW DELHI, March 12:
A 30-member team of scientists and researchers from the National Institute of Oceanography (NIO) in Panaji (Goa) and another 30 crew members onboard its research vessel Sindhu Sadhana were flagged off at Visakhapatnam (also known as Vizag) in Andhra Pradesh on Thursday on a first-of-its-kind research project in this country to map the Indian Ocean genome.
They will spend the next three months traversing the course of over 10,000 nautical miles in the Indian Ocean on a research project to reveal the internal working of the body of the ocean at a cellular level.
The research project is aimed at understanding the biochemistry and the response of the ocean to climate change, nutrient stress and increasing pollution. Conceptualised over the last two to three years, the research project has been undertaken at a cost of INR 250 million and will take three years to complete, NIO Director Sunil Kumar Singh said.
The scientists and researchers, including six women, will sail across the Indian Ocean from India’s east coast, all the way to Australia, then onward towards Port Louis in Mauritius and up to the border of Pakistan, off India’s west coast. They will gather samples for genome mapping of microorganisms in the Indian Ocean. They will collect samples from various stretches of the ocean at an average depth of about 5 km.
Just like gene-mapping is carried out on blood samples collected from humans, the scientists will map these in the bacteria, microbes found in the ocean. The mapping of the Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA) will show the nutrients present in them, and also those lacking in different parts of the ocean.
NIO Director Singh says this will help scientists understand the internal working of the ecosystem of the Indian Ocean. The research will enable scientists to identify the factors controlling the changes in RNA, DNA in the oceans, and various stressors impacting them.
The ocean has several micronutrients like nitrates, sulphates and silicates, minerals like iron ore and zinc, and trace metals like cadmium or copper. The genome mapping will show the presence of which these microbes have adapted to, in addition to their reaction to atmospheric carbon dioxide. This will help in identifying which part of the ocean has a greater concentration of which mineral or element.
The scientists will then use these as tracers to tackle the causative factors for excess or lack of a certain mineral or element and suggest possible solutions for their mitigation. In addition, the large pool of RNA, DNA library of the oceans will be utilised for using the Indian Ocean to human benefit in the future.
According to the NIO, rapid advances in sequencing technologies and bioinformatics have enabled exploration of the ocean genome. “Exploring the ocean genome will enable an increase in the growing number of commercial biotechnology applications, extending from multiple anticancer treatments to cosmetics and industrial enzymes, to antiviral molecules… Exploration of the ocean at a genetic level will result in new insights into taxonomy and adaptive capacity that can help optimize conservation efforts,” the NIO said in its project abstract.
Trace metals like cadmium or copper are supplied to oceans via continental run-offs, atmospheric deposition, hydrothermal activities and continental shelf interaction. They are essential for ocean productivity. Scientists say that it is important to understand the interactions of trace metals with marine biota “for having a holistic understanding about nutrient cycling and productivity of the oceans”.
Apart from their reactions on marine life, isotopic forms of trace metals can be utilised to track the movement of water masses responsible for ocean circulation and as tools to study the biological, geochemical and ecosystem processes and food web analyses.
The NIO’s project is expected to generate new information about trace metals from underexplored regions of the Indian Ocean, the third largest water body in the world, covering about 20 per cent of the Earth’s water surface.
The team of scientists will stay aboard their research vessel for about 90 days with refuelling scheduled at Mauritius. The route is from Visakhapatnam to the mouth of the Ganga then down the ocean to Australia, then westward to Mauritius and up to the Pakistan border. At various stages and stretches, samples will be collected by lowering a Kevlar cable of up to 8 km with a set of 24 teflon coated bottles to collect samples. They have a capacity of 12 litres.
The Kevler cable and the Teflon coating are to ensure that metals are not inadvertently introduced into the water by the vessel itself. The samples will be collected and the bacteria will be stored at -60 degrees Celsius with the help of liquid nitrogen. While some samples will be tested at six laboratories on board the vessel, several samples will be brought back to NIO for study and analysis over the next three years.

Expert: Mismanagement of CEB hydro resources increases costly oil-powered electricity generation

The Ceylon Electricity Board (CEB) is in one of the strongest hydro storage positions in recent memory, but it has mismanaged key hydropower complexes, causing an increase in oil-powered electricity generation and and costs.
Energy expert Dr. Vidura Ralapanawe has raised serious concerns over CEB’s operational decisions, particularly the skewed use of the Mahaweli and Laxapana hydropower complexes. “By mid-May, the system had ample storage — about 60% overall — which is actually a very good position to be in just before the South-West monsoon rains,” he said. “But within that headline figure is a huge imbalance. Mahaweli reservoirs are near 75%, while Laxapana is languishing at 30%.”
This lopsided storage has already caused direct operational problems. The Canyon power station, which is fed by the Maussakele Reservoir in the Laxapana complex, has been forced to reduce its output. The 60MW plant is now operating at just 40MW due to limited water availability. Downstream, the 100MW New Laxapana station is similarly constrained.
The Laxapana complex is not just another hydropower asset — it plays a vital role in Colombo’s drinking water supply. It is required to run continuously to maintain flows for water treatment plants. “That means the CEB must generate from Laxapana 24/7, no matter what,” Ralapanawe said. “So how did they allow it to reach such a critically low level, especially when Mahaweli reservoirs are full?”
Ralpanawe said: “Instead of making adjustments to maintain operational flexibility, the CEB appears to have run the Laxapana complex harder than necessary in previous months while underutilising Mahaweli, where Victoria and Randenigala are sitting comfortably. The consequence? More reliance on oil-based thermal generation, even as the country’s dams remain well-stocked.”
“This is not just a technical problem — it’s an economic one,” he stressed. “Oil is expensive. When you underutilise hydropower in a year like this, you’re actively choosing to drive up the cost of generation.”
The apparent lack of coordination between the Mahaweli and Laxapana systems is especially baffling given the CEB’s long-standing familiarity with both. “The CEB has operated these systems for over 40 years. They know the inflows, the rainfall patterns, the seasonal irrigation releases — none of this is new,” Ralapanawe said.
Moreover, the growing integration of AI and data-driven forecasting tools in the global energy sector makes such mismanagement increasingly indefensible. “If, in the age of AI, we’re still hearing that ‘it’s too complex’ to manage these reservoirs in tandem, then something is seriously wrong,” he added.
Dr. Ralapanawe urges the CEB to provide an explanation: “Why was Mahaweli underdispatched when it was full? Why was Laxapana overused to the point that we now can’t get full capacity from critical plants like Canyon and New Laxapana? What is the economic impact of burning more oil than necessary?”
The missteps are already costing the public. Higher generation costs will ultimately be passed on to consumers in the form of increased tariffs, a burden made heavier in an already strained economy,” says Dr. Ralapanawe.
Ironically, 2025 was shaping up to be a strong hydro year, offering a rare opportunity for cost savings and reduced fossil fuel use. Instead, mismanagement has left key reservoirs unbalanced and locked the system into a more expensive operating mode — one that benefits oil suppliers but punishes the average household and industry.
Dr. Ralapanawe’s message is blunt: “This is not just about water and electricity. This is about public accountability and economic responsibility. If the CEB cannot manage two hydro systems properly with decades of data at its fingertips, then it must rethink its leadership and planning structures — or risk repeating the same costly mistakes year after year.”
Our efforts to contact CEB officials for comment were in vain.

Million Lankan women workers will lose their jobs if Trump’s 44 % tariff goes into effect

As many as a million Lankan women workers in key export sectors will lose their jobs and income if the 44 percent tariffs imposed by US President Donald Trump come into force at the end of the 90-day pause, Asia News has reported.
Sri Lanka’s main export industries, such as apparel, tea, gems, rubber and cinnamon, that employ mostly women, will be the most affected by the new tariffs since the US market is one of their most lucrative.
Apparel workers reproach the government for its “lethargic attitude” and failure to consider the concerns of workers and unions, not least because their representatives were not asked to participate in the discussions on tariffs.
The apparel industry accounts for about 40 percent of the country’s total exports, and is crucial for its economy. It also employs mainly women from low-income backgrounds in rural areas, for whom these jobs represent a crucial pathway out of poverty.
Since most apparel workers are also breadwinners, their wages help extended family networks in economically disadvantaged regions.
“The Women’s Centre collaborated with 25 other women’s organisations to carry out our campaign against the US tariffs hindering women workers,” said its Executive Director, Padmini Weerasuriya.
If the tariffs go into effect, “Their take-home pay will decrease significantly,” she added. “As orders dip and approximately six million dependents will also be severely impacted.”
“These women need job security as factories are already discussing about possible layoffs of workers, since demand is likely to drop.”
Compared to India and Bangladesh, she warns, Sri Lankan women face greater competition since “the tariffs imposed on Sri Lanka are higher”. That is why several manufacturers are already moving their operations to Vietnam, Bangladesh and Africa.
If plants shut down, more than 350,000 women working will be impacted. AsiaNews met three of them, 33-year-old Subadra Aponsu, 31-year-old Hemamamli Akaravita and 30-year-old Sandamini Tissera who spoke about their difficulties.
“We are the breadwinners of our families as our parents are elderly and sick. Our siblings are married and they are unable to provide for our parents. During the past several years, we have been working hard and providing for our families. If we lose our jobs, we have no option but to mortgage our homes,” they explained.
“During the economic crisis, we had to sell our paddy fields. Currently, our employers are planning to leave the country. We may lose our jobs shortly. We are unable to find employment elsewhere as almost every apparel manufacturer is planning to sell their business. In our boarding house, several women have already lost their jobs.”
According to economic analysts Sampath Amarasinghe and Niroshini Caldera, “due to the new tariffs, there will be a significant decline in export volumes with a severe erosion of Sri Lankan goods’ competitiveness in US markets.” All this, they warn, could result in “many Sri Lankan products ending up out of reach for US consumers and businesses.”
The greatest risk concerns “price- and cost-sensitive categories like garments, where profit margins are already low and competition from other countries is intense.”
The new tariff will see exports to the United States drop by 20 percent, with an annual loss of about US$ 300 million in foreign currency earnings.
As Sri Lanka’s total exports of goods in 2024 reached US$ 13 billion, the experts conclude, this represents “a major blow to the country’s balance of trade” and “economic growth prospects”.
Meanwhile, several women’s groups started a petition last week in the Katunayake Free Trade Zone (the first and largest of the country’s eight FTZs). – (AsiaNews)

Sri Lanka reiterates commitment to repeal PTA in talks with EU

Sri Lanka has again declared its commitment to repeal the Prevention of Terrorism Act (PTA) during the recently concluded talks with the European Union.
At the eighth meeting of the Working Group on Governance, Rule of Law and Human Rights under the EU-Sri Lanka Joint Commission, held in Colombo, Sri Lankan representatives “confirmed the commitment to repeal the Prevention of Terrorism Act (PTA), and briefed the Working Group on the timeline to replace it with new counter-terrorism legislation in compliance with international norms and standards.”
The PTA has long drawn criticism from civil society, rights organisations, and international observers. The law has enabled arbitrary detention and torture for decades, particularly against Tamils. Despite repeated pledges by successive governments, no comprehensive repeal has yet materialised.
Though the National People’s Power (NPP)-backed government has stated its commitment to repeal the PTA during election campaigns last year, once in power it has not yet taken legislative action to do so.
The following is the text of the joint statement issued by the government and the EU: The eighth meeting of the Working Group on Governance, Rule of Law and Human Rights under the EU-Sri Lanka Joint Commission was held in Colombo on 5 May.
The Working Group discussed a range of matters of mutual interest, including efforts to combatting corruption, upholding human rights including labour rights; rights of persons belonging to minorities; women’s rights; child rights; a conducive space for civil society; strengthening electoral processes; and preventing discrimination based on gender and sexual orientation.
During the discussions, the European Union congratulated Sri Lanka on the well-organised and peaceful Presidential and Parliamentary elections last year and Sri Lanka appreciated the European Union Election Observation Mission at the Presidential elections.
The European Union also congratulated Sri Lanka on the stabilisation of the economy, continued efforts towards recovery and important initiatives such as the Government Action Plan for the implementation of governance reforms based on the IMF recommendations. Sri Lanka briefed the European Union on the adoption of the National Action Plan to Combat Corruption as well as steps taken to strengthen the Commission to Investigate Allegations of Bribery or Corruption (CIABOC). The EU and Sri Lanka agreed on the importance of governance and judicial processes to strengthen the rule of law. The Sri Lanka side briefed the EU on the steps being taken by the Government since its election to strengthen the democratic process, governance, rule of law and the legal framework for protecting and promoting human rights. They agreed on the important role of civil society organisations, particularly in fostering inclusive and consultative legislative processes within democratic societies.
The Working Group reiterated its shared commitment to promote and protect human rights and to collaborate, as applicable, on the effective implementation of international human rights instruments. Sri Lanka confirmed the commitment to repeal the Prevention of Terrorism Act (PTA), and briefed the Working Group on the timeline to replace it with new counter-terrorism legislation in compliance with international norms and standards. The European Union recalled the need to bring relevant legislation in line with international Human Rights and ILO conventions to ensure continued access to the European market through the GSP+ trade preferences.
The European Union welcomed the commitment of the Government to end discrimination and build national unity, as well as the pledge to strengthen the truth and reconciliation framework in Sri Lanka, through an inclusive and participative process of all communities.
The EU and Sri Lanka reiterated their commitment to continue to work in the multilateral UN framework and continue their engagement with the Office of the High Commissioner for Human Rights and the Human Rights Council.
The European Union and Sri Lanka also reaffirmed their shared commitment to continuing to support a multilateral, rules-based international order grounded in international law, with the United Nations at its core.
The conclusions and recommendations of the Working Group will be reported to the EU-Sri Lanka Joint Commission to be held in Colombo during the latter half of the year.
The Delegation of Sri Lanka was led by Sugeeshwara Gunaratna, Director-General/ Europe and North America Division of the Ministry of Foreign Affairs, Foreign Employment and Tourism. The Delegation of the European Union was led by Charles Whiteley, Head of the South Asia Division of the European External Action Service.
