This is an ongoing project led by NatCen International in collaboration with the University of Bristol, and partners based in Vietnam, Social Life Research Institute and Institute for Development and Community Health "Light".


Precarious outdoor workers in urban areas of the Global South are one of the groups most exposed to the impacts of climate change. But the impact is thinly understood and policies to address such exposure under-developed.

This project explores the (in)visible vulnerabilities and multiple health exposures of these workers in Vietnam, a lower-middle income country (LMIC) experiencing rapid urbanisation and with a large informal sector. 

Focus on street venders, riders and porters and construction workers in Hanoi (in the North), Da Nang (Central), Ho Chi Minh City (South) and Can Tho (Mekong Delta Region).
