Evaluating value-for-money of policy interventions to strengthen health system resilience to extreme weather events in South Africa
Supervisors: Dr Saeideh Babashahi, Dr Collins Iwuji, Prof D Kniveton
Application deadline: Friday 31 January, 2025
Competition Funded PhD Project (UK Students Only)
About the Project
Applications are invited for a 3-year funded PhD studentship at Brighton and Sussex Medical School. This PhD will be nested within the ASTRA project, an NIHR-funded project led by BSMS investigating health system and community resilience to extreme weather events amongst people living with HIV (PLHIV) and or tuberculosis in South Africa, Zambia and Mozambique.
Project details
Climate change is now a top global priority with the WHO stating that it is the biggest health threat facing humanity. Climate change is projected to further increase the number and severity of heat waves, floods and droughts, causing disproportionate increases in injury, illness and death in vulnerable populations already burdened with wide-ranging health conditions. Future health risks will be determined not just by the hazards created by a changing climate, but also by the (in)ability of healthcare services to meet the needs of different population groups. While much is understood about the direct impact of extreme weather events (EWEs) on ill-health, less is known about indirect routes, such as population displacements and damage to infrastructure which could equally impact the health of vulnerable populations (e.g. HIV/TB) through interrupting access to or hindering health service provision.
ASTRA is an NIHR-funded research project that aims to engage and involve stakeholders, including the community, to co-design and deliver research that proposes, prioritises and evaluates interventions to strengthen community and health system resilience to EWEs to reduce negative impacts on people living with HIV and/or tuberculosis in Mozambique, South Africa and Zambia.
The PhD will be nested within ASTRA and aims to estimate the costs of proposed interventions to strengthen health system resilience to the impacts of climate change versus the costs of inaction (baseline scenario) in South Africa using economic evaluation methods and systems dynamic modelling as well as the effectiveness of the proposed interventions using multi-criteria decision analysis (MCDA) as part of the larger research project of ASTRA.
Research Environment
The ASTRA project is led by the University of Sussex (UOS) with collaborators from South Africa [the Africa Health Research Institute, (AHRI), KwaZulu-Natal), Zambia (Zambart, Lusaka) and Mozambique (Aurum Institute).
AHRI is an independent non-profit research institution supported with core funding from the Wellcome Trust for over 20 years. AHRI’s strategic scientific focus areas include HIV, tuberculosis, neglected and emerging infections, adolescent mental health, non-communicable diseases and climate change and health. UOS and AHRI have an established research collaboration since 2017 fostered by Prof Iwuji. The student will be provided with a workspace at AHRI and Brighton and Sussex Medical School. At AHRI, the student will become part of a network of PhD students and will have access to seminars and training courses when at AHRI.
The primary supervisor, Dr Babashahi, is based full-time at UOS but leads another climate and health research at AHRI that is estimating economic impacts (e.g. productivity losses) following EWEs. She is a health economist and an expert on the MCDA approach that will be used by the student.
The secondary supervisor, Professor Collins Iwuji, is the principal investigator of ASTRA, and although employed by University of Sussex, splits his time between AHRI and University of Sussex. He is an expert on how climate change impacts HIV. He will provide insight into service provision for HIV care during EWEs. It is envisaged that the student will spend about 18 months at AHRI during the PhD.
The tertiary supervisor, Prof Dominic Kniveton, is based full time at University of Sussex. Dom is a climate and systems modeller who is a member of the Lancet Countdown: Tracking the connections between public health and climate change. He has been lead and co-supervisor for 17 PhD students.
Although the student will spend part of their time at AHRI, they would have the opportunity to interact with the multidisciplinary team collaborating on this multi-country projects, through both face-to-face and online meetings.
Entry requirements
This studentship is suitable for those with background in Economics, Climate Science, and other relevant background in Social Sciences. We invite applications from students who have received or are on target to achieve a relevant undergraduate degree with minimum 2:1 classification (or equivalent). Proficient mixed-method analysis background and experience in coordinating multi-stakeholder workshops are desirable but not essential.
How to apply
Applicants must apply through the University of Brighton application Portal (StudentView) where they can submit a CV and complete the application form. The deadline for applications is 1st February 2025. Interviews will be held on Friday 28 February 2025. Informal enquiries are welcome and should be submitted to Dr Saeideh Babashahi (S.Babashahi@bsms.ac.uk) and Prof Collins Iwuji (C.Iwuji@bsms.ac.uk).
Funding Notes
This is a 3-year PhD studentship funded by Brighton and Sussex Medical funded, starting on 1st October 2025. Funding will cover tuition fees for UK students (at the Home rate), a stipend at the UKRI rate and a research allowance which will cover research running costs. International applicants are welcome to apply but will be required to cover the difference between Home and International fees.
