Researchers in Singapore have embarked on a 15-month plan to study the environmental effects of the June 14 oil spill on intertidal areas, aiming to understand its impact on biodiversity.

The national plan was announced by Minister for National Development Desmond Lee on 8 October 2024, during a marine science workshop held at the National University of Singapore (NUS).

This initiative will involve multiple local institutions, including the National Parks Board (NParks), St John’s Island National Marine Laboratory, and the National Institute of Education (NIE).

The research team will focus on monitoring the impact of the oil spill on various intertidal areas, which include East Coast Park, Labrador Nature Reserve, and Sentosa.

Additionally, the study will incorporate data from beaches not directly affected by the spill, such as those at Changi Beach Park and Coney Island Park. According to NParks, this approach will enable researchers to compare data and isolate the specific impact of the oil spill on marine life.

Focus on Intertidal Biodiversity

The research involves collecting and analysing sediment samples from both affected and unaffected coastal areas.

Dr Tan Koh Siang, a principal research fellow at NUS Tropical Marine Science Institute (TMSI), highlighted the importance of the study, noting that the oil spill’s impact could range from smothering tiny organisms to disrupting their physiological functions due to exposure to toxic chemicals.

“These [organisms] have not really been looked at, so we are interested to see what effects the oil has on these communities that are not visually obvious,” Dr Tan said.

The process will include sieving sediment samples to identify and count various invertebrates, such as small crustaceans, worms, and molluscs. These data will provide insights into the community structure of these organisms, forming a baseline for future studies on environmental changes and the resilience of Singapore’s coastal ecosystems.

Details of the Oil Spill

The June 14 oil spill occurred when the Netherlands-flagged dredger Vox Maxima collided with the stationary bunker vessel Marine Honour at Pasir Panjang Terminal.

The incident resulted in the release of approximately 400 tonnes of low-sulphur fuel oil into the sea.

The spill subsequently spread to several biodiversity-rich areas along Singapore’s southern coast, including Sentosa, Labrador Nature Reserve, the Southern Islands, and East Coast Park. By 16 June, the oil was sighted off the coast of Changi as well.

The spill coincided with a marine heatwave, which had led to a bleaching event affecting about 40% of hard corals in the shallow waters of the Southern Islands.

This overlap between the oil spill and environmental stressors like increased sea-surface temperatures has made monitoring efforts more crucial, as the long-term impact on local marine life could be compounded.

Extended Monitoring and Marine Environment Sensing Network

In addition to sediment sampling, researchers plan to leverage existing research initiatives, such as the Marine Environment Sensing Network (MESN).

This project involves deploying research buoys that monitor seawater conditions, including temperature, salinity, acidity levels, and nutrient concentrations.

Currently, one buoy is deployed off St John’s Island, with plans to install two more in the coming months.

Dr Jani Tanzil, facility director of St John’s Island National Marine Laboratory, noted that this data would help in understanding environmental changes and could differentiate between the ecological impacts of the oil spill and other disturbances like the heatwave.

Government Response and Recovery Efforts

Minister Desmond Lee emphasized the need for sustained monitoring efforts to assess both the immediate and longer-term effects of the oil spill.

“While there’s been no significant impact on our marine biodiversity observed thus far, there could be a time lag between the incidence of the oil spill and its effect on biodiversity… We need to continue to monitor the impact, and the recovery, of our marine habitats,” he said.

The data from this monitoring phase will inform potential mitigation and restoration strategies, helping to protect biodiversity-rich areas along Singapore’s coastlines. These efforts will be vital in guiding the recovery of affected ecosystems and ensuring that similar incidents are managed effectively in the future.

Clean-Up Operations 

In the weeks following the spill, Singapore undertook extensive clean-up efforts.

On 3 September 2024, Grace Fu, Minister for Sustainability and the Environment, shared an update on Instagram, stating, “I am happy to share that we have completed our clean-up at public spaces from the effects of the oil spill that happened on 14th June. 800 cleaning personnel, 2,300 volunteers, 3,750 tonnes of debris later, we have completed the task for cleaning, ahead of schedule! 💪”

In August 2024, Dennis Tan Lip Fong, Member of Parliament for Hougang SMC, inquired about the status of beach and coastal clean-up operations during a parliamentary session. Minister Grace Fu provided an update, stating that the clean-up is progressing well, with some beaches reopening for activities. The first phase of the operation has concluded, while the second phase focuses on areas with oil trapped deeper in the sand and more challenging spots like rock bunds and breakwaters. Volunteer efforts are also being mobilised to accelerate the reopening of beaches, with the clean-up expected to complete within a month.

However, when pressed for details on clean-up costs and the financial impact on local businesses, Minister Grace Fu noted that the government has yet to finalise expense calculations. She added that the immediate focus remains on completing the clean-up operations and restoring normalcy to affected coastal areas.

EU urged to designate Sarawak as ‘high risk‘ under anti-deforestation law

A coalition of environmental and Indigenous groups has called on the EU to designate Sarawak as high risk under its anti-deforestation law. Sarawak’s extensive deforestation and Indigenous rights violations pose serious risks, prompting calls for stricter EU import checks on timber and palm oil products from the region.

A coalition of environmental, human rights, and Indigenous organizations is urging the European Union (EU) to classify Malaysia’s Sarawak state as “high risk” under its new anti-deforestation regulation. Sarawak, home to millions of hectares of ancient rainforests, faces severe deforestation risks and violations of Indigenous peoples’ rights, according to a joint assessment by groups including Human Rights Watch, RimbaWatch, and SAVE Rivers.

The call to action comes ahead of the EU’s pending decision to categorize regions based on their deforestation risks under the new law.

The EU Deforestation-Free Products Regulation (EUDR), set to be enforced from January 2025, aims to curb the import of commodities like timber and palm oil linked to deforestation and human rights violations.

Sarawak’s history of deforestation, especially for timber and oil palm plantations, makes it a significant concern. A high-risk designation under the EUDR would lead to stricter import checks and increased due diligence requirements for EU companies dealing with products from Sarawak.

Land Rights Violations and Deforestation Concerns

The coalition’s analysis highlights Sarawak’s controversial land laws, which undermine Indigenous land rights while promoting commercial exploitation of the state’s forests.

According to Luciana Téllez Chávez, senior environment and human rights researcher at Human Rights Watch, Sarawak’s land code places “insurmountable obstacles” on Indigenous communities’ ability to gain legal recognition for their ancestral lands.

These laws allow companies to operate with impunity, often disregarding Indigenous land claims. The coalition argues that Sarawak’s record justifies a “high risk” classification, which would necessitate increased oversight of timber and palm oil imports into the EU.

Sarawak’s ambitious plans to expand industrial timber plantations, aiming to establish one million hectares by 2025, are another point of concern.

Achieving this goal would require converting over 400,000 hectares of naturally regenerating forests between 2022 and 2025. This trend poses a significant threat to biodiversity and the rights of Indigenous peoples.

Deficiencies in Certification and Transparency

Despite Sarawak’s reliance on the Malaysian Timber Certification Scheme (MTCS), civil society organizations have flagged significant flaws in the program.

Local activists argue that MTCS does not adequately protect Indigenous rights or prevent deforestation. Celine Lim, managing director of SAVE Rivers, emphasizes that logging continues on Indigenous lands without proper consultation or consent, further eroding trust in certification standards.

Additionally, Sarawak’s opaque land management practices hinder transparency. The state has not made available comprehensive data on Indigenous lands or disclosed the locations of leases granted to logging and palm oil companies.

This lack of transparency prevents Indigenous communities and civil society from holding companies and the government accountable.

EU’s Role in Enforcing Sustainable Practices

Under the EUDR, the European Commission will classify regions as “low, standard, or high risk” by the end of 2024.

A high-risk designation for Sarawak would mandate EU member states to triple their customs checks on imports of wood and palm oil products from the region.

EU-based companies would also need to conduct more rigorous checks to mitigate environmental and human rights violations linked to these products. This process would require close collaboration between the EU and Malaysian authorities to reduce risks and ensure compliance with the new regulation.

Sarawak’s timber and palm oil exports to the EU have been significant in recent years. According to a Sarawak government report, the state exported at least MYR 37.3 million (€7.8 million) worth of timber to EU countries like the Netherlands, France, and Greece in 2023.

The EU remains the third-largest market for Malaysian palm oil exports, underscoring the importance of Sarawak’s compliance with international sustainability standards.

Challenges in Malaysian Government Response

The Malaysian government has pushed back against the EUDR, criticizing its definitions and monitoring processes.

The government contends that industrial timber plantations, which involve replacing natural forests with single-species plantations, should not be classified as deforestation. Critics argue that this stance overlooks the environmental degradation and loss of biodiversity associated with such practices.

Adam Farhan, director of RimbaWatch, warns that Malaysia may be attempting to bypass EU restrictions by downplaying the scale of deforestation in timber plantations. Farhan stresses the need for stringent due diligence on Malaysian forest-risk commodities.

The federal government has mandated that palm oil plantations established after 31 December 2019, on deforested land, cannot receive sustainable certification under the Malaysian Sustainable Palm Oil (MSPO) standard.

However, enforcement remains uncertain, as states hold jurisdiction over land and forest administration. Civil society groups are urging the Malaysian government to strengthen its oversight mechanisms and improve its sustainability certification programs to meet EU requirements.

International and Local Advocacy for Reform

In May 2024, the coalition of civil society organizations submitted recommendations to Malaysia’s federal Plantation and Commodities Ministry, urging reforms to align with international human rights and environmental standards.

Key recommendations include incorporating the United Nations Declaration on the Rights of Indigenous Peoples into federal legislation and introducing laws to prevent strategic lawsuits against public participation (SLAPPs), which are often used to silence critics of deforestation practices. The government has not yet responded to these calls.

As the EU moves forward with its anti-deforestation law, the decision to designate Sarawak as high risk could have far-reaching implications for Malaysia’s timber and palm oil industries. Environmental groups argue that strong enforcement of the EUDR is necessary to prevent further forest loss and protect Indigenous communities’ rights in Sarawak.

Japanese scientists find microplastics are present in clouds

In Japan, researchers confirm microplastics in clouds, impacting climate. Airborne microplastics, 7.1 to 94.6 micrometers in size, found in cloud water, potentially affecting rapid cloud formation and climate systems.

WASHINGTON, UNITED STATES — Researchers in Japan have confirmed microplastics are present in clouds, where they are likely affecting the climate in ways that aren’t yet fully understood.

In a study published in Environmental Chemistry Letters, scientists climbed Mount Fuji and Mount Oyama in order to collect water from the mists that shroud their peaks, then applied advanced imaging techniques to the samples to determine their physical and chemical properties.

The team identified nine different types of polymers and one type of rubber in the airborne microplastics — ranging in size from 7.1 to 94.6 micrometers.

Each liter of cloud water contained between 6.7 to 13.9 pieces of the plastics.

What’s more, “hydrophilic” or water-loving polymers were abundant, suggesting the particles play a significant role in rapid cloud formation and thus climate systems.

“If the issue of ‘plastic air pollution’ is not addressed proactively, climate change and ecological risks may become a reality, causing irreversible and serious environmental damage in the future,” lead author Hiroshi Okochi of Waseda University warned in a statement Wednesday.

When microplastics reach the upper atmosphere and are exposed to ultraviolet radiation from sunlight, they degrade, contributing to greenhouse gasses, added Okochi.

Microplastics — defined as plastic particles under 5 millimeters — come from industrial effluent, textiles, synthetic car tires, personal care products and much more.

These tiny fragments have been discovered inside fish in the deepest recesses of the ocean peppering Arctic sea ice and blanketing the snows on the Pyrenees mountains between France and Spain.

But the mechanisms of their transport have remained unclear, with research on airborne microplastic transport in particular limited.

“To the best of our knowledge, this is the first report on airborne microplastics in cloud water,” the authors wrote in their paper.

Emerging evidence has linked microplastics to a range of impacts on heart and lung health, as well as cancers, in addition to widespread environmental harm.
