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.

Farmers need to plan grazing better, says UFS expert

“Farmers should save veld during the summer months to have grazing available for animals especially in the winter and early spring. Farmers should also adjust livestock numbers timely and wisely according to the available material in the field,” says Prof HO de Waal, professional animal scientist and affiliated researcher in the Department of Animal, Wildlife and Grassland Sciences at the University of the Free State.

He offered this advice as a result of the sporadic and scattered (scant) rainfall of the past couple of summers. “In retrospect we know that this kind of precipitation started in about 2014 and has continued in subsequent summers. In February 2015, it was clear that a major fodder scarcity was developing.”

Existing research methods serve as source of current knowledge
Dr Herman Fouché (Agricultural Research Council) has conducted research on the impact of climate, especially rainfall, on the growth of grass. Sophisticated computer technology developed as far back as the 1980s to – through modelling – predicts the impact of climate on field production during the growing season.

The impact of climate, and more specifically rainfall, on field production has been known to animal and grazing scientists for a long time. Prof De Waal used the modelling results to determine the impact of rainfall on grass as a feeding source for animals.

“Information that emerged from this old research programme could therefore be applied directly to animal production,” says Prof De Waal.

Adjust livestock numbers to availability of grazing
In the summer rainfall areas of South Africa, grass usually grows from the end of August and early September. The growth process is dependent on the transfer of soil moisture, as well as on rainfall during the winter and early spring.

“Livestock numbers should be balanced throughout the year (according to the nutritional needs and production of the animals) with the availability of grazing material – be consistent, not only during certain seasons or when drought is imminent,” is Prof De Waal’s advice to farmers. “Farmers are also encouraged to carefully reduce the number of livestock on grazing and to rather focus their attention and limited resources on the remaining breeding herds (cows and ewes).”

“It is tragic, but unfortunately many farmers will not survive the effects of recent years. Similar climatic conditions will occur, with the same tragic consequences for man and beast. Better planning has to start now.” The assistance of private institutions, individuals, as well as the government, during the severe droughts is gratefully acknowledged.

Spineless cactus pear as solution for scarcity of animal feed
Prof De Waal says spineless cactus pears could be used as a feeding source during droughts. “The effects of a severe drought, or major animal-feed scarcity, are still prevalent in large parts of the subcontinent.” This may act as a catalyst to utilise spineless cactus pears as a feeding source and to be incorporated in the feed-flow programme for livestock on natural grazing.
