Climate change, health and well-being in urbanising Southeast Asia

Precarious outdoor workers in urban megacities, especially in the global South, are among the most exposed to climate change impacts. In Vietnam, where rapid urbanisation and a large informal workforce shape the landscape, outdoor workers face heightened health risks due to extreme weather conditions. These conditions are worsening with climate change, the risks are underexplored, and the policies to address these risks are still in early development.
The project “The health impacts of climate change on precarious outdoor workers in megacities in Vietnam,” funded by the Wellcome Trust, sought to fill critical knowledge gaps by exploring the health vulnerabilities and climate-related risks faced by outdoor workers in urban Vietnam. In partnership with the University of Bristol, SocialLife Research Institute, Vietnam Medical Association, Institute for Development & Community Health LIGHT, and local worker communities in Vietnam, this research is producing new evidence-based insights to inform policy solutions on the climate change-induced health risks faced by vulnerable outdoor workers in urban contexts. These findings will help policymakers devise interventions that align with the realities of outdoor workers' lives and working conditions.
To launch the project, we hosted a one-day event that brought together key stakeholders, including government officials, academics, experts, practitioners, civil society, and funders. The event showcased some preliminary findings, highlighted the project's significance, and facilitated in-depth discussions on the challenges and opportunities associated with addressing climate change-related health risks in the global South.
Sherman Tai is a Senior Researcher at NatCen International. His research interests are social movements, political radicalization and state violence, especially when they at once respond to and are produced by global processes such as international migration, inequality and imperialism. He has presented his work on the role of nonviolent protestors in the tactical radicalization of the 2019 Hong Kong Protests in conferences held by Academia Sinica, Taiwan; the British Journal of Sociology; and the American Sociological Association. He is experienced in quantitative, qualitative and mixed methods research, particularly in-depth interviews, pre-post survey evaluations and regression analyses using R and Python.
Prior to joining NatCen International, he was a Consultant at PwC Hong Kong and provided strategic, economic and financial advisory for government departments and private sector market players on high-profile and large-scale infrastructure and urban developments. He holds an MSc in Political Sociology from the London School of Economics, and a BSocSci in Government with a Minor in Sociology from the Chinese University of Hong Kong. He spent a year at the University of Warwick as an exchange student in Politics and International Studies.
Sokratis is Director of Health Policy at NatCen. He is a Chartered Psychologist and an Associate Fellow of the British Psychological Society. He has been responsible for the design and management of research projects, including national surveys, qualitative studies and systematic reviews and evaluations in the field of gambling harm, health risk profiles and epidemiology.
He has managed the design of national evaluation projects related to the effectiveness of mental health, social services, and policy initiatives in the UK. This includes an evaluation of the Credit Card Ban for Gambling in Great Britain and evaluation of the Voluntary, Community, and Social Enterprise Covid-19 Emergency Funding Package on behalf of DCMS.
Sokratis also led a project to improve understanding of how patterns of online play relate to the potential for gambling harm. This involved the collection of account-based data from several gambling operators. He led the chapter on mental health inequalities in the DHSC’s White Paper and has also reviewed large grants for ESRC and NIHR as well as academic publications for several journals.
