Most plastic debris on beaches comes from far-off sources

Lankan plastic debris found on beaches in the Seychelles

Vast amounts of plastic debris accumulate on beaches across the Seychelles and other small island developing states including Sri Lanka, and an observational analysis (for instance, plastic bottle labels) suggest that much of this waste originates from distant sources and not from the islands themselves.

But until now, the likely sources of this debris have not been quantified, says a new study by the University of Oxford.

“Indonesia is the primary source of land-based plastic debris found on beaches in the Seychelles, with major contributions from India and Sri Lanka,” it said.

The study led by the University of Oxford investigated by developing a high-resolution model that simulated the movement of plastic debris across the world’s oceans. This used input data on ocean currents, waves, and winds, and plastic debris entering the ocean from coastal populations, rivers and fisheries, to predict plastic debris accumulation at 27 sites in the Seychelles and wider western Indian ocean. The results have been published in Marine Pollution Bulletin.

The researchers modelled the likely sources of both land-based and marine types of plastic pollution.

Key findings:

• Indonesia is the primary source of land-based plastic debris found on beaches in the Seychelles, with major contributions from India and Sri Lanka. This was particularly the case for medium-large debris that have a high buoyancy (such as bottle caps, sandals, bottles, and small domestic items).

• Plastic debris arriving from Indonesia would have been at sea for at least 6 months, with some exceeding 2 years.

• Smaller plastic debris, such as millimetre-sized plastic fragments and pellets, tended to originate from East Africa and from within the Seychelles itself. Smaller fragments are less buoyant than larger items, and do not travel as far before sinking.

• The Seychelles also accumulate significant amounts of plastic debris of marine origin from fisheries and shipping lanes, such as discarded or lost fishing gear. The large numbers of bottles beaching at these islands with labels suggesting they come from Malaysia, Thailand and, in particular, China, were probably discarded from ships rather than floating from those countries directly. For some islands, a significantly higher proportion of plastic waste comes from marine sources, rather than land.

• Rates of plastic debris accumulation showed a strong seasonal affect. Plastic debris from both land and marine sources was most likely to land on beaches in the Seychelles at the end of the northwest monsoon, with the highest rates in March and April.

• Plastic debris accumulation may also be amplified by El Niño-Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD, also known as the Indian Niño) events.

This is the first study to produce a quantitative estimate of the sources of plastic debris for the Seychelles and other remote islands in the western Indian Ocean. Such plastic pollution is a significant environmental threat, both for marine ecosystems and the communities that depend on the ocean for food, tourism, and other economic activities. In addition, plastic debris that drifts from far-off sources increases the risk of spreading invasive species and diseases.

A previous study led by University of Oxford researchers estimated that over 500 tonnes of debris had accumulated at Aldabra Atoll in Seychelles, an ecologically valuable UNESCO World Heritage Site with zero permanent population.

Lead author of the current research, Noam Vogt-Vincent (Department of Earth Sciences, University of Oxford), said ‘We have combined observational data from across the Seychelles with cutting-edge computer simulations to generate the most comprehensive predictions currently available for marine litter dispersal in the region. This will provide vital information for local management on these islands — many of which are global biodiversity hotspots — and to inform national and international responses.’

According to the researchers, the results illustrate the sheer scale of the plastic pollution challenge facing small island developing states, and makes the need for a global plastic treaty more urgent than ever. This could include, for instance, greater enforcement of policies that forbid the disposal of fishing gear and other plastics at sea. The findings also build on the ever-growing evidence that investing in waste management systems and implementing policies for waste disposal at the main source nations is the number one action to prevent land-based litter arriving at remote island sites.

Knowing when plastic debris accumulation is likely to peak could help to plan mitigation efforts. For instance, the results suggest that beach clean-ups should take place after peak debris accumulation (i.e. May to June) to reduce the likelihood of plastic debris breaking down into smaller fragments and impacting ecosystems.

Co-author Dr April Burt (Seychelles Islands Foundation and University of Oxford) said: ‘These islands are faced with the deeply inequitable situation of bearing the costs of removing waste they were not responsible for generating, contrary to the “polluter pays” principle. Our study has demonstrated that most of the plastic debris accumulating at these remote islands comes from far-off sources, and this should be the first positive step towards accountability and prevention.’

The study also involved researchers from the University of Montpellier; the Institut de Recherche pour le D’eveloppement, MARBEC; and the Okinawa Institute of Science and Technology

BASL asks govt. to abandon plan to raise retirement ages of CA and SC judges

Published

… tells Prez such arbitrary change neither necessary nor desirable

The Bar Association of Sri Lanka (BASL) has urged President Anura Kumara Dissanayake to abandon the controversial plan to increase the retirement age of the judiciary, including the Court of Appeal and the Supreme Court.

In a statement issued by the BASL President Rajeev Amarasuriya and its Secretary Nalin de Silva, the BASL pointed out that the proposed increase of the retirement age of the judiciary would undermine the independence, integrity, dignity, and public confidence in the Judiciary, which is essential for the maintenance of the Rule of Law and democratic governance in Sri Lanka.

The text of the BASL statement: “The Bar Association of Sri Lanka (hereinafter referred to as “BASL”) notes with grave concern reports in the public domain that the Government is considering the introduction of an amendment to the Constitution to increase the age of retirement of Judges of the Court of Appeal and the Supreme Court.

It is the considered view of the BASL that the age of retirement of the judges of the Court of Appeal and the Supreme Court which has stood at 63 years and 65 years respectively from the promulgation of the 1978 Constitution, should not be changed arbitrarily and that such a change is neither necessary nor desirable.

To do so will result in the loss of public confidence in the integrity of the legal system and of the Government’s commitment to preserve and protect the rule of law and the independence of the judiciary. Members of the public are likely to question the motives of the Government in bringing in a Constitutional amendment solely for this purpose.

Your Excellency is no doubt aware that the cadre of the Judges of the Court of Appeal was increased from 12 to 20 Judges (including the President of the Court of Appeal) and that of the Supreme Court from 11 to 17 Judges (including the Chief Justice) by the 20th Amendment to the constitution certified on 29th of October 2020. With such enhancement, workwise, there cannot be a real requirement to extend the retirement ages of these judges.

Your Excellency is aware that altering the retirement age of judges of the apex courts would have to be done through a Constitutional amendment. For many years Sri Lanka’s Constitution has been subject to ad hoc amendments, sometimes in order to cater to the political needs of the government in power and often contrary to the interests of the rule of law, the independence of the judiciary and the judiciary.

Extending the retirement age of the sitting Judges of these Courts at this point of time is likely to be viewed by the public as a blatant attempt to interfere with the judiciary. We believe that to go ahead with such an ad hoc move will also be an affront to the Honourable Judges of those courts.

If the Government goes ahead with such a move it will set a dangerous precedent for future Governments too to introduce ad hoc amendments to the Constitution in respect of the functions of the Judiciary.

The independence of the Judiciary and the public confidence reposed in it, are indispensable pillars of the Rule of Law and the democratic framework of our Republic. In that regard, it is of paramount importance that the Judiciary must not only remain independent in fact, but must also be seen by the public to be wholly independent, impartial, and free from even the slightest perception of influence, favour, accommodation, or impropriety.

The Bar Association of Sri Lanka is therefore constrained, in the discharge of its duty to uphold and safeguard the Rule of Law and the independence of the Judiciary, to respectfully express its serious concern regarding any such proposed amendment, which is neither in the interests of the Judiciary and nor of the people.

In the circumstances, the BASL respectfully urges Your Excellency not to proceed with any proposed constitutional amendment seeking to increase the retirement age of the members of the Judiciary including Judges of the Court of Appeal and the Supreme Court.

We remain confident that Your Excellency will give due consideration to the importance of preserving and protecting the independence, integrity, dignity, and public confidence in the Judiciary, which is essential to the maintenance of the Rule of Law and democratic governance in Sri Lanka.”

Govt. declines to respond

A member of the Cabinet yesterday declined to comment on the BASL’s letter to President Anura Kumara Dissanayake. The Minister said that he wouldn’t comment for the time being.

New US tariffs proposed on 60 countries, including Sri Lanka

Published

12.5% additional duties on goods imported from Colombo

The US has proposed additional duties of 10% or 12.5% on imports from 60 economies, including Sri Lanka, over their alleged failure to curb trade in ‌goods made with forced labour.

The proposal made by US Trade Representative’s (USTR) office in terms of Section 301 unfair trade practices investigation to be released, news agencies reported, pointing out that the Trump administration was seeking to rebuild its emergency tariffs, which were struck down by a US Supreme Court decision in February.

The USTR said it determined that it would impose 10% duties related to ⁠the forced labour investigation on imports from Canada, Ecuador, the European Union, Indonesia, Mexico, Pakistan, Argentina, Bangladesh, Cambodia, El Salvador, Guatemala, Indonesia, Malaysia, Taiwan and Britain.

The trade agency said it would impose additional duties of 12.5% on the remaining 45 countries that were investigated.

“The failure of our most important trading partners to address the importation of goods made with forced labour is unacceptable,” US Trade Representative Jamieson Greer said in a statement. “This creates a dynamic where American workers are forced to compete globally on an unlevel playing field.”

According to the trade agency, the USTR found that Sri Lanka has failed to impose and effectively enforce a forced labour import prohibition.

The USTR noted that the results of its investigation indicate that the acts, policies and practices of Sri Lanka related to the failure to impose and effectively enforce a forced labour import prohibition are unreasonable and burden or restrict US commerce.

Accordingly, it has proposed to impose 12.5% additional duties on goods imported from Sri Lanka.

The USTR said it also was proposing a textile mechanism that would allow for a certain volume of apparel and textile imports ‌to ⁠enter the US at a reduced tariff rate, though the duties and volumes were not disclosed.

The announcement comes ahead of the July 24 expiration of a 10% temporary tariff imposed by the Trump administration on February 20, the day the Supreme Court struck down US President Donald Trump’s tariffs under the International Emergency Economic Powers Act.

On Monday, the USTR proposed ⁠a 25% duty on many Brazilian goods as a result of a Section 301 investigation into the country’s digital trade practices and preferential tariffs. The trade agency is also expected to soon unveil the findings of another major Section 301 probe into ⁠the buildup of excess industrial capacity in 16 trading partners, including China.

In the forced labour findings, the USTR said it would exempt from the tariffs a number of products, including energy, rare earths and certain ⁠other metals, beef, coffee, certain fruits and vegetables, pharmaceuticals, organic chemicals and aircraft parts.

The USTR said it would accept public comments on the proposed tariffs and other remedies through July 6, with a public hearing scheduled for July 7.
