Abstract:
Global warming, the increase in heatwaves and periods of intense heat, is a major problem across the
world, including in South Africa. Heat exposure has adverse health impacts, ranging from dehydration and
heat stroke to death. The transport sector and its users are vulnerable to heat exposure both in vehicles
and in places where they wait for transport. We investigated the heat perceptions and experiences of
minibus commuters and the minibus taxi industry in minibus taxis and minibus taxi ranks to inform an
intervention to prevent adverse health impacts from heat exposure in the City of Tshwane. Commuters
(n = 279), drivers and marshals (n = 46) reported feeling hot in minibus taxis and minibus taxi ranks,
experiencing sweating, headaches, exhaustion and dizziness. Some participants reported opening
windows and doors, drinking water/cold drinks, removing a jersey and fanning themselves to try and
cool down. All participants suggested solutions to address heat exposure in minibus taxis and minibus
taxi ranks, including more shelters and trees for shade, the provision of water, benches and potentially an
air-conditioned building for waiting/holding periods between trips. In consultation with our stakeholders,
we prepared educational awareness materials about heat risks to health and actions to take when it is hot,
and these were distributed through the minibus taxi sector in the City of Tshwane. Future research needs
include measuring temperatures in these settings and rolling out large-scale interventions to protect health
and well-being in a changing climate.
SIGNIFICANCE :
Heat exposure has adverse health impacts, ranging from dehydration to death. The transport sector and
its users are vulnerable to extreme heat. We investigated the heat experiences and perceptions of minibus
commuters and the minibus taxi industry to inform an intervention to prevent adverse health impacts from
heat exposure in the City of Tshwane. We prepared educational awareness materials about heat risks to
health and actions to take when it is hot, and these were distributed through the minibus taxi sector. Future
research needs include measuring temperatures in these settings and rolling out large-scale interventions to
protect health and well-being in a changing climate.
