Dr Herkulaas Combrink is representing UFS in a new international research project that aims to improve how evidence is used in public health policymaking.

Dr Herkulaas Combrink, a senior lecturer in the Faculty of Economic and Management Sciences (EMS) at the University of the Free State (UFS), is representing the university in a new international research project that aims to improve how evidence is used in public health policymaking.

Dr Combrink, who is also a co-director of the Interdisciplinary Centre for Digital Futures (ICDF), has been selected as one of the principal investigators in a newly funded project supported by the UK’s International Science Partnerships Fund under the Evidence-Informed Policymaking Programme. Running from April 2025 to March 2026, the project – titled Integrating Evidence for Contextualised Public Health Policy: Lessons from South Africa – explores how different types of evidence can be used more effectively in shaping public health policy. The international collaboration includes researchers from the Centre for Philosophy of Epidemiology, Medicine and Public Health, which is a collaboration between Durham University and the University of Johannesburg; as well as Durham’s Centre for Humanities Engaging Science and Society.

 

From the Free State to global impact

For Dr Combrink, being part of this collaboration highlights the important work being done in the faculty and ICDF that is reaching beyond borders. 

“It’s important to showcase the impact we are making from the Free State that leads to global outcomes,” he said.

The project aims to evaluate an evidence mapping framework to determine how model-based projections and social listening reports can be more effectively integrated and contextualised for policymaking.

“These are two very different data types,” he explained. “The value lies in demonstrating how to apply the framework to different contexts for evidence-based mapping.”

Dr Combrink brings extensive expertise to the team, having worked on both disease modelling and risk communication during South Africa’s COVID-19 response. He was involved in national and provincial social listening initiatives, and used high-frequency social media data to track the spread of misinformation, often referred to as the ‘infodemic.’ 

“We’ve built up enough data within ICDF and EMS to support this study,” he noted.

The goal is not just theoretical. A key outcome of the project is engaging directly with policymakers to refine modelling and risk communication strategies for future pandemics. 

“This will help us to engage with the various departments of health to assist with improving modelling and risk communication work for better social behavioural change,” he explained.

According to Prof Brownhilder Neneh, Vice-Dean for Research and Internationalisation in the EMS faculty, the project reflects the faculty’s growing global presence. 

“Dr Combrink’s participation is a testament to the calibre of scholarship within the faculty,” she said. “It positions EMS as a key contributor to shaping policy and practice with societal impact.”

She added that the collaboration aligns well with the faculty’s vision for global partnerships that are rooted in local relevance.

“By focusing on contextualised evidence for policymaking, this project reflects our commitment to relevance, engagement and global partnership,” she said.

 

What comes next

Over the project’s 12-month timeline, the team will deliver:

• a case study analysis of modelling and social listening during South Africa’s COVID-19 response;
• an extended evidence mapping framework tailored to diverse evidence types;
• policy briefs and practical tools for public health practitioners; and
• a hybrid international workshop in late 2025 bringing together researchers, policymakers and health professionals to test and refine these outputs.

Census 2011 overshadowed by vuvuzela announcements

Census 2011 contains good statistics but these are overshadowed by vuvuzela announcements and a selective approach, economist Mike Schüssler said at a presentation at the UFS.

“Why highlight one inequality and not another success factor? Is Government that negative about itself?” Mr Schüssler, owner of Economist.co.za, asked.

“Why is all the good news such as home ownership, water, lights, cars, cellphones, etc. put on the back burner? For example, we have more rooms than people in our primary residence. Data shows that a third of Africans have a second home. Why are some statistics that are racially based not made available, e.g. orphans? So are “bad” statistics not always presented?”

He highlighted statistics that did not get the necessary attention in the media. One such statistic is that black South Africans earn 46% of all income compared to 39% of whites. The census also showed that black South Africans fully own nearly ten times the amount of houses that whites do. Another statistic is that black South Africans are the only population group to have a younger median age. “This is against worldwide trends and in all likelihood has to do with AIDS. It is killing black South Africans more than other race groups.”

Mr Schüssler also gave insight into education. He said education does count when earnings are taken into account. “I could easily say that the average degree earns nearly five times more than a matric and the average matric earns twice the pay of a grade 11.”

He also mentioned that people lie in surveys. On the expenditure side he said, “People apparently do not admit that they gamble or drink or smoke when asked. They also do not eat out but when looking at industry and sector sales, this is exposed and the CPI is, for example, reweighted. They forget their food expenditure and brag about their cars. They seemingly spend massively on houses but little on maintenance. They spend more than they earn.”

“On income, the lie is that people forget or do not know the difference between gross and net salaries. People forget garnishee orders, loan repayments and certainly do not have an idea what companies pay on their behalf to pensions and medical aid. People want to keep getting social grants so they are more motivated to forget income. People are scared of taxes too so they lower income when asked. They spend more than they earn in many categories.”

On household assets Mr Schüssler said South Africans are asset rich but income poor. Over 8,3 million black African families stay in brick or concrete houses out of a total of 11,2 million total. About 4,9 million black families own their own home fully while only 502 000 whites do (fully paid off or nearly ten times more black families own their own homes fully). Just over 880 000 black South Africans are paying off their homes while 518 000 white families are.

Other interesting statistics are that 13,2 million people work, 22,5 million have bank accounts, 19,6 million have credit records. Thirty percent of households have cars, 90% of households have cellphones and 80% of households have TVs.
