Ecological Engineering — Dr Jacques Maritz, Albert van Eck, and Dr Nola Redelinghuys are among the University of the Free State researchers driving an interdisciplinary project that combines social insight, high-performance computing, and ecological engineering to support South Africa’s just energy transition.

The University of the Free State (UFS) is taking bold steps to address the complexities of South Africa’s energy transition by combining expertise across disciplines, innovative technologies such as high-performance computing (HPC), and active student involvement. This forward-thinking approach is positioning the UFS at the forefront of solving real-world challenges linked to renewable energy adoption and social dynamics, while equipping students with future-ready skills.

Interdisciplinary solutions for a just energy transition

“Current grand challenges – the pressing societal and scientific problems shaping research at the UFS and globally – require students and researchers to include computational approaches such as modelling, simulations, and large-scale data analysis,” says Dr Jacques Maritz, Head of the Unit for Engineering Sciences at the UFS.

“One such example is in merging social dynamics with energy paradigms – two seemingly different worlds, yet connected via scientific elegance,” says Dr Maritz. Energy decisions, such as shifting to renewables, are shaped by the behaviour of communities, governments, and industries. As a recent response to these challenges, ecological and nature-based engineering sciences at the UFS aim to integrate human activity into nature, while benefiting both via the merging of computation, ecological engineering sciences, nature-based solutions, and data-driven complexity science.

The UFS’ pioneering project models these complex social-energy relationships to better understand how South Africa can sustainably and justly transition from fossil fuels to renewable energy. This interdisciplinary effort involves researchers and students from physics, sociology, engineering, data science, and mathematical modelling working together to map these interdependencies shaped by economic, political, cultural, and community forces.

For students such as Lurgasho Minnie, a final-year MSc Astrophysics student, this interdisciplinary exposure is transformative. “It has given me a new lens or perspective on approaching and solving problems in my field of research. By approaching challenges from an interdisciplinary point of view, new methods and techniques can be applied to solve challenging problems,” he says.

A crucial part of this research involves modelling dynamic social-energy networks using systems thinking, network analysis, and scenario planning. These tools help simulate interactions between government policies, community behaviour, environmental impacts, and technological innovations, allowing researchers to predict and plan for different future scenarios.

Students are actively shaping this work. The first set of social data was collected by UFS students on the Qwaqwa Campus, with training and support from the Centre for Global Change and Student Affairs. These data-gathering efforts are not only enriching the research but also building students' skills in real-world data collection and analysis.

“One of the study objectives is to inform the development of an awareness campaign about the complexities inherent in transitioning from a predominantly non-renewable to a renewable energy system, firstly aimed at UFS students but ultimately at the broader community,” explains Dr Nola Redelinghuys, Senior Lecturer in Sociology at the UFS.

The research team also hopes to help shape sustainable energy solutions for the university itself, with plans to create a renewable energy supply network that balances energy demand and renewable supply across the UFS campuses.

High-performance computing powering new insights

At the heart of this initiative is the UFS High-Performance Computing (HPC) Unit, which enables researchers to run complex simulations and process vast data sets. The HPC is essential for solving problems that require immense computing power and data storage, and the UFS is making these resources accessible to a growing number of students – even those from non-computational disciplines.

“The eResearch and HPC team promotes the development of new skills and knowledge to harness the power of HPC and expand one’s technological abilities to solve problems. The HPC staff must first train a student or researcher to use the system effectively before using their toolsets. Thereafter, students can streamline or even automate specific processes by using a collection of more generic toolsets. Even if not using an HPC daily (or after entering the workforce), the HPC methodologies and toolsets they are exposed to often change how a person approaches future problem sets. Students using the HPC are more likely to share their experiences and are encouraged to assist other students in their department to lessen the burden of entry for newcomers. This broadens the collective knowledge within a department on their toolsets and how to use them effectively,” says Albert van Eck, Director of the UFS HPC.

Students can also learn how to build and configure basic HPC clusters through freely available training materials, opening doors to careers in private cloud hosting, data science, genomics, and other tech industries. By focusing on open-source tools, the UFS ensures that students acquire industry-relevant skills without being locked into specific software vendors.

The project is also laying the groundwork for partnerships with renewable energy companies, technology firms, NGOs, and development agencies. These collaborations will strengthen the UFS’ industry ties and create more work-integrated learning (WIL) opportunities for students.

As part of UFS Vision 130, this project advances academic excellence, societal impact, and inclusivity. By involving diverse staff and students from both the Bloemfontein and Qwaqwa Campuses, it demonstrates the university’s commitment to building a future-ready, skilled, and socially conscious graduate community prepared to tackle South Africa’s energy challenges.

In a country grappling with energy security and the need for a just transition, the UFS’ approach – blending social insight, cutting-edge technology, and student empowerment – offers a valuable model for addressing one of the nation’s most pressing development priorities.

CONTROL OF INFECTIOUS AVIAN DISEASES – LESSONS FOR MAN?

“Many of the lessons learnt in disease control in poultry will have application on human medicine,” said Prof Robert Bragg, lecturer at the University of the Free State’s (UFS) Department of Microbial, Biochemical and Food Biotechnology during his inaugural lecture.

Prof Bragg said the development of vaccines remains the main stay of disease control in humans as well as in avian species. Disease control can not rely on vaccination alone and other disease-control options must be examined.

“With the increasing problems of antibiotic resistance, the use of disinfection and bio security are becoming more important,” he said.

“Avian influenza (AI) is an example of a disease which can spread from birds to humans. Hopefully this virus will not develop human to human transmission,” said Prof Bragg.

According to Prof Bragg, South Africa is not on the migration route of water birds, which are the main transmitters of AI. “This makes South Africa one of the countries less likely to get the disease,” he said.

If the AI virus does develop human to human transmission, it could make the 1918 flu pandemic pale into insignificance. During the 1918 flu pandemic, the virus had a mortality rate of only 3%, yet more than 50 million people died.

Although the AI virus has not developed human-to-human transmission, all human cases have been related to direct contact with infected birds. The mortality rate in humans who have contracted this virus is 67%.

“Apart from the obvious fears for the human population, this virus is a very serious poultry pathogen and can cause 100% mortality in poultry populations. Poultry meat and egg production is the staple protein source in most countries around the world. The virus is currently devastating the poultry industry world-wide,” said Prof Bragg.

Prof Bragg’s research activities on avian diseases started off with the investigation of diseases in poultry. “The average life cycle of a broiler chicken is 42 days. After this short time, they are slaughtered. As a result of the short generation time in poultry, one can observe changes in microbial populations as a result of the use of vaccines, antibiotics and disinfectants,” said Prof Bragg.

“Much of my research effort has been directed towards the control of infectious coryza in layers, which is caused by the bacterium Avibacterium paragallinarum. This disease is a type of sinusitis in the layer chickens and can cause a drop in egg product of up to 40%,” said Prof Bragg.

The vaccines used around the world in an attempt to control this disease are all inactivated vaccines. One of the most important points is the selection of the correct strains of the bacterium to use in the vaccine.

Prof Bragg established that in South Africa, there are four different serovars of the bacterium and one of these, the serovar C-3 strain, was believed to be unique to Southern Africa. He also recently discovered this serovar for the first time in Israel, thus indicating that this serovar might have a wider distribution than originally believed.

Vaccines used in this country did not contain this serovar. Prof Bragg established that the long term use of vaccines not containing the local South African strain resulted in a shift in the population distribution of the pathogen.

Prof Bragg’s research activities also include disease control in parrots and pigeons. “One of the main research projects in my group is on the disease in parrots caused by the circovirus Beak and Feather Disease virus. This virus causes serious problems in the parrot breeding industry in this country. This virus is also threatening the highly endangered and endemic Cape Parrot,” said Prof Bragg.

Prof Bragg’s research group is currently working on the development of a DNA vaccine which will assist in the control of the disease, not only in the parrot breeding industry, but also to help the highly endangered Cape Parrot in its battle for survival.

“Not all of our research efforts are directed towards infectious coryza or the Beak and Feather Disease virus. One of my Masters students is currently investigating the cell receptors involved in the binding of Newcastle Disease virus to cancerous cells and normal cells of humans. This work will also eventually lead to a possible treatment of cancer in humans and will assist with the development of a recombinant vaccine for Newcastle disease virus,” said Prof Bragg.

We are also currently investigating an “unknown” virus which causes disease problems in poultry in the Western Cape,” said Prof Bragg.

“Although disinfection has been extensively used in the poultry industry, it has only been done at the pre-placement stage. In other words, disinfectants are used before the birds are placed into the house. Once the birds are placed, all use of disinfectants stops,” said Prof Bragg.

“Disinfection and bio security can be seen as the ‘Cinderella’ of disease control in poultry. This is also true for human medicine. One just has to look at the high numbers of people who die from hospital-acquired infections to realise that disinfection is not a concept which is really clear in human health care,” said Prof Bragg.

Much research has been done in the control of diseases through vaccination and through the use of antibiotics. “These pillars of disease control are, however, starting to crumble and more effort is needed on disinfection and bio security,” said Prof Bragg.

Prof Bragg has been working in close co-operation with a chemical manufacturing company in Stellenbosch to develop a unique disinfectant which his highly effective yet not toxic to the birds.

As a result of this unique product, he has developed the continual disinfection program for use in poultry. In this program the disinfectant is used throughout the production cycle of the birds. It is also used to ensure that there is excellent pre-placement disinfection.

“The program is extensively used for the control of infectious diseases in the parrot-breeding industry in South Africa and the product has been registered in 15 countries around the world with registration in the USA in the final process,” said Prof Bragg.

“Although the problem of plasmid mediated resistance to disinfectants is starting to rear its ugly head, this has allowed for the opening of a new research field which my group will hopefully exploit in the near future,” he said.
