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.

Position statement: Recent reporting in newspapers
2014-10-03

 

You may have read reports in two Afrikaans newspapers, regarding recent events at the University of the Free State (UFS). Sadly, those reports are inaccurate, one-sided, exaggerated and based not on facts, but on rumour, gossip and unusually personal attacks on members of the university management.

Anyone who spends 10 minutes on our Bloemfontein Campus would wonder what the so-called ‘crisis’ is about.

We are left with no choice other than to consider legal action, as well as the intervention of the South African Press Ombudsman, among other steps, to protect the good name of the institution and the reputation of its staff. No journalist has the right to launch personal and damaging attacks on a university and its personnel, whatever his or her motives, without being fair and factual. In this respect, the newspapers have a case to answer.

But here are the facts in relation to the reports:

  1. No staff member, whether junior or senior, is ever suspended without hard evidence in hand. Such actions are rare, and when done, are preceded by careful reviews of our Human Resource Policies, labour legislation and both internal and external legal advice. Then, and only then, is a suspension affected. A suspension, moreover, does not mean you are guilty and is a precautionary action to allow for the disciplinary investigation and process to be conducted, especially where there is a serious case to answer.
  2. At no stage was the Registrar instructed to leave the university; this is patently false and yet reported as fact. We specifically responded to the media that the Registrar does outstanding work for the university and that it is our intention for him to remain as our Registrar through the end of his contract in 2016.
  3. The Rector does not make decisions by himself. Senior persons, from the position of Dean, upwards, are appointed by statutory and other senior committees of the university and finally approved by Council. No rector can override the decision of a senior committee, and this has not happened at the UFS even in cases where the Rector serves as Chair of that committee. The impression of heavy-handed management at the top insults all our committee structures, including the Institutional Forum – the widest and most inclusive of stakeholder bodies at a university – which reports directly to Council on fairness and compliance of selection processes.
  4. In the case of senior appointments, Council makes the final decision. Council fully supports the actions taken on senior appointments, including a recent senior suspension. The fact that one Council member resigns just before the end of his term, whatever the real reason for this action, does not deter from the fact that the full Council in its last sitting approved the major staffing decisions brought before it. The image therefore that the two newspapers try to create of great turmoil and distress at the university, is completely unfounded.

Even if we wanted to, the university obviously cannot provide details about staffing decisions, especially disciplinary actions in process, since the rights of individuals should be protected in terms of the Human Resource Policies and procedures of the UFS. But that does not give any newspaper the right to speculate or state as fact that which is based on rumour or gossip, or to slander senior personnel of the university. For these reasons, we have been forced to seek legal remedy and correction as a matter of urgency.

Make no mistake, underlying much of the criticism of the university has been a distress about transformation at the UFS; in particular, the perception is created that white colleagues are losing their jobs. The evidence points in the opposite direction. Our progress with equity has been slow and we lag far behind most of the former white universities; that is a fact. More than 90% of our professors are white; most of our senior appointments at professorial level and as heads of department are still overwhelmingly white. Reasonable South Africans would agree that our transformation still has a long way to go and only the mean-spirited would contend otherwise. But based on the two Afrikaans newspaper reports, an impression is left of the aggressive rooting out of white colleagues.

In the past few years the academic standard of the university has significantly improved. We now have the highest academic pass rates in years, in part because we raised the academic standards for admission four years ago. We now have the highest rate of research publications, and among the highest national publication rate of scholarly books, in the history of the UFS. We have one of the most stable financial situations of any university in South Africa, with a strong balance sheet and growing financial reserves way beyond what we had before. We now attract top professors from around the country and other parts of the world, and we have the highest number of rated researchers, through the National Research Foundation, than ever before. And after the constant turmoil of a number of years ago, we now have one of the most stable campuses in South Africa. Those are the facts.

The UFS is also regarded around the world as a university that has become a model of transformation and reconciliation in the student body. The elections of our Student Representative Council are only the most visible example of how far we have come in our leadership diversity. Not a week goes by in which other universities, nationally and abroad, do not come to Kovsies to consult with us on how they can learn from us and deepen their own transformations, especially among students.

Rather than focus on what more than one senior journalist, in reference to the article in Rapport of 21 September 2014, rightly called ‘a hatchet job’ on persons and the university, here are the objective findings of a recent survey of UFS stakeholders: 92% endorse our values; 77% agree with our transformation; 78% believe we are inclusive; and 78% applaud our overall reputation index.  Those are very different numbers from a few years ago when the institution was in crisis.

This is our commitment to all our stakeholders: we will continue our model of inclusive transformation which provides opportunities for study and for employment for all South Africans, including international students and colleagues. We remain committed to our parallel-medium instruction in which Afrikaans remains a language of instruction; we are in fact the only medical school in the country that offers dual education and training in both Afrikaans and English for our students - not only English. We provide bursaries and overseas study opportunities to all our students, irrespective of race. And our ‘future professors’ programme is richly diverse as we seek the academic stars of the future.

We are not perfect as a university management or community. Where we make mistakes, we acknowledge them and try to do better the next time round. But we remain steadfast in our goal of making the UFS a top world university in its academic ambitions and its human commitments.
