NTU launches new research facility to study health risks of climate change in the tropics
SINGAPORE - A new research centre that aims to tackle the health risks of climate change in the tropics was launched at Nanyang Technological University on April 15.
Research efforts at the Centre for Climate Change and Environmental Health will focus on three pillars – air quality, extreme heat, and water supply and quality, said its director Steve Yim.
These are issues that are becoming increasingly urgent in South-east Asia due to rising global temperatures and environmental changes, he added.
Associate Professor Yim said there is a significant lack of research focusing on tropical regions like South-east Asia, which faces issues specific to the region. These include high humidity, monsoons and transboundary haze pollution, all of which have impacts on human health and well-being.
'South-east Asia is one of the regions most exposed to climate-related health risks, yet remains under-represented in global research,' he said.
The centre was officially launched at the Experimental Medicine Building at NTU on April 15. Senior Minister of State for Sustainability and the Environment Amy Khor was the guest of honour.
Dr Khor said Singapore, being a highly urbanised and densely populated city-state, is exceptionally vulnerable to climate impacts on its environment and public health.
For example, climate change causes changes in rainfall patterns and a higher likelihood of extreme weather events. This potentially contributes to the increase and spread of various vector-borne diseases, especially arboviruses, which are those spread by mosquitoes, according to the Duke-NUS Medical School.
'(The centre's research) will build on findings from Singapore's Third National Climate Change Study to advance our understanding of tropical climate variability and its potential impact on Singapore and the larger South-east Asia region,' she added.
The new centre will bring together researchers at NTU who conduct research in the domains of climate and health. These experts come from NTU's Lee Kong Chian School of Medicine, Asian School of the Environment, Earth Observatory of Singapore, Singapore Centre for Environmental Life Sciences Engineering, and Nanyang Environment & Water Research Institute .
Over the next five years, they will be trained in interdisciplinary studies on the health impact of climate change, said Prof Yim.
'By bringing together experts across fields and partnering with regional centres, we will develop practical solutions to help governments, hospitals and communities respond more effectively.'
The centre also aims to establish a regional consortium to bring universities and health institutes from Indonesia, India, Thailand, Taiwan and Britain together to study the relationship between human health and climate change in the three research areas.
Imperial College London's Medical Research Council Centre for Environment and Health was revealed as one contributing member of the consortium.
Local partners like the National Environment Agency and Ministry of Sustainability and Environment are also expected to contribute in supporting the development of evidence-based policies and solutions.
Between 2030 and 2050, climate change is expected to cause approximately 250,000 additional deaths per year from malnutrition, malaria, diarrhoea and heat stress alone, according to the World Health Organisation. The direct damage costs to health are estimated to be between US$2 billion (S$2.63 billion) and US$4 billion per year by 2030.
Additionally, around 489,000 heat-related mortalities had been reported annually between 2000 and 2019, with an estimated 45 per cent of cases in Asia.
Unicef had also in February 2025 reported that more than 100 children under the age of five die each day in East Asia and the Pacific from air pollution-related causes.
Research done under the centre would add to pre-existing interdisciplinary research on the climate-health nexus being conducted by NUS entities.
This includes the Heat Resilience and Performance Centre and Centre for Sustainable Medicine at the NUS Yong Loo Lin School of Medicine, as well as the Climate, Environment and Health programme by Saw Swee Hock School of Public Health.
Existing studies are being further developed under the centre, including one led by Prof Yim, and co-authored by Dr Tao Huang, a research fellow at NTU's Lee Kong Chian School of Medicine and the Centre for Climate Change and Environmental Health.
The study looks at how heat caused by greenhouse emissions and air pollution combine to affect human health in various regions across the world.
The project currently involves the joint collaboration between researchers and PhD students from NTU's Lee Kong Chian School of Medicine, Earth Observatory of Singapore and Asian School of the Environment. They recently received a grant to collaborate with experts from the National University of Singapore and Stanford University School of Medicine.
'Many government agencies like the National Environment Agency, National Parks Board and Land Transport Authority have also supported us by offering us real-time information like weather-related data, urban morphology and traffic data respectively. We hope we will be able to work with more organisations through this centre to expand on the study,' said Dr Huang.
Such studies show how climate change is a multidisciplinary topic that requires the combined knowledge of climate science, environmental science and health science, Prof Yim said.
However, he said the different organisations are not working as effectively as they should be with one another.
'We now have to fix this problem. (The centre) thus offers a platform for multiple perspectives to work with each other to understand and tackle issues in a more robust manner, so that we can provide feasible solutions for policymakers,' he said.

NTU researchers using cloud technology to develop tools for food safety
Scientists in Singapore are harnessing special viruses that kill only bacteria to keep food safe for longer. The use of phage technology is also aimed at tackling the growing problem of anti-microbial resistance in food. Used with cloud-based AI tools, bacterial contamination can be potentially cut by more than 90% in just half an hour. Professor William Chen and Professor Chen Lin from NTU's Food Science and Technology Programme shared more about using cloud-based tools in food applications.

Vape bins placed in Singapore's six autonomous universities to encourage voluntary disposal
Sign up now: Get ST's newsletters delivered to your inbox Each university has placed one bin on campus and is assessing the need for more. SINGAPORE – Vape disposal bins have been placed at Singapore's six autonomous universities as part of a national push to tackle the rising trend of vaping among youth. The bins are part of the Health Sciences Authority (HSA) and People's Association (PA)'s 'Bin the Vape' campaign , which encourages users to voluntarily dispose of their vapes without penalty. Possessing, using or buying vapes carries a maximum fine of $2,000, but the authorities said no action will be taken against those who voluntarily dispose of their vapes. These bins have been placed at 23 community clubs and one residents' network centre around the island, including in Punggol, Boon Lay, Mountbatten, Woodlands and Bishan. The move aims to foster a supportive, stigma-free environment for those trying to quit vaping, said the Singapore Institute of Technology (SIT). Each university has placed one bin on campus and is assessing the need for more. The move was announced in a circular sent to students and staff around last week. Under the law, it is an offence to possess, purchase or use e-vaporisers or related products. Top stories Swipe. Select. Stay informed.

In response to queries from The Straits Times, all six universities said they take a firm stance against vaping. Students caught will face disciplinary actions and may be reported to the authorities. But those who voluntarily surrender their devices or seek help to quit will not be penalised. The institutions also said they are stepping up education and enforcement efforts to maintain a vape-free campus. The National University of Singapore (NUS) and Nanyang Technological University (NTU) said offenders living on campus may be suspended and barred from such housing. The National University of Singapore (NUS) said those residing on campus may be suspended or barred from such housing. NTU added that vaping on campus, regardless of e-vaporiser content, will constitute a breach of NTU's code of conduct. During orientation programmes, freshmen will be reminded of the illegality and dangers of vaping and of the university's strict stance against vaping. Its halls of residence will also issue circulars on NTU's policy. Those caught vaping on campus, regardless of vape content, may face disciplinary actions such as fines or being barred from staying in NTU's halls of residences, or be required to go for counselling. They must also attend a vaping cessation programme conducted by HSA. The Singapore University of Social Sciences (SUSS) said it jointly enforces a strict no-vaping policy with the Singapore Institute of Management on their shared campus. It has put up 'no vaping' banners, and conducts regular security patrols. It uses CCTV surveillance to deter and detect violations. SUSS added that students found vaping on campus will have their devices confiscated, their personal details recorded, and be reported to HSA. Meanwhile, NUS said those who witness vaping activities on campus can make a report through its whistleblowing channel. The Singapore Management University (SMU) said it maintains a general whistleblowing policy, which allows individuals to report in good faith any improper activities, including those that affect safety or well-being. 'We recognise that students may turn to vaping for various reasons – such as stress, peer influence, or curiosity – and encourage those who wish to stop vaping to seek confidential support through our wellness centre or HPB's QuitLine on 1800-438-2000,' said SMU. The Singapore University of Technology and Design (SUTD) said its campus is smoke-free and it has strict rules to maintain a safe and healthy environment. All incoming freshmen attend an orientation session on residential life that includes a segment on the risks and consequences of drugs and vaping. The Ministry of Health (MOH) is in the process of classifying etomidate, a sedative increasingly found in vapes, as a Class C controlled drug under the Misuse of Drugs Act. Ahead of the law taking effect in the coming weeks, MOH is offering an amnesty period when users can surrender their devices or seek help to quit without facing any penalties. Once the law kicks in, those caught using etomidate-laced vapes will face mandatory supervision and rehabilitation. Under current laws, those caught selling, importing or distributing such vapes could face jail and caning.
