Critical Dialogue
Guest speaker, Prof Gordon Zide, delivers his keynote address at the EDSA Critical Dialogue Series 2025.

The Office of the Executive Director: Student Affairs at the University of the Free State (UFS) hosted its annual Critical Dialogue Series on 29 April 2025 at the Centenary Complex on the Bloemfontein Campus. The dialogue brought together students, staff, and university leadership for an engaging conversation around ethical and servant leadership in higher education.

 

A conversation rooted in purpose

In his opening address, Temba Hlasho, Executive Director for Student Affairs said the dialogue was designed to provoke honest reflection and engagement on issues that affect student experience and institutional culture.

“We believe that there has to be some sort of transparency in terms of having to talk about topical issues that are very critical, that also touch on the very nerve of student experience,” Hlasho said.

He encouraged student leaders to see the platform not as ceremonial, but as a call to action. “You are in a country today where ethics have almost decayed. You, as the future of this country, will rely solely on the young people to change the narrative.”

 

Leadership anchored in service

UFS Vice-Chancellor and Principal Prof Hester C. Klopper delivered a powerful message on the importance of ethical and servant leadership in guiding the university’s direction. “Leadership – and specifically ethical and servant leadership – forms the cornerstone of what we stand for at the University of the Free State.”

She spoke about accountability, fairness, and leading with integrity. “It means treating every student fairly regardless of background or belief, and holding yourself accountable for your actions and decisions.”

Prof Klopper also highlighted the vital role student leaders play in shaping a culture of trust and excellence. “Leadership is not a title or a position, but a daily choice to serve with integrity, empathy, and purpose.”

 

Ubuntu, transformation, and power dynamics

The event’s keynote speaker was Prof Gordon Zide, an accomplished scholar, academic, intellectual, Africanist, author, transformation specialist, motivational speaker, and a former Vice-Chancellor and Principal of the Vaal University of Technology. Prof Zide is also a former Registrar at the University of South Africa. Drawing from a lifetime of experience in the sector, he interrogated the moral responsibilities of leadership within the South African higher education landscape.

“Leadership is a function of being a servant and being in charge of others,” he said. “It also requires the capacity to give strategic direction for the effective, efficient, and valued functioning of organisations.”

He emphasised that ethical leadership should be grounded in values such as vision, passion, patience, integrity, honesty, decisiveness, character, and charisma. Reflecting on the African philosophy of ubuntu, Prof Zide remarked: “When talking about servant leadership, it’s important to recognise other people and say to yourself: ‘I am what I am because of other people.’”

He encouraged students, particularly the current generation, to take charge and assume ethical leadership roles in their spaces. Referencing prominent anti-apartheid figure Robert Sobukwe, he urged, “Even when we are no longer here, they will always remember that we were there.”

Prof Zide also noted the practical benefits of ethical leadership in institutions, saying that it improves brand image, boosts morale among staff and students, and strengthens the recruitment process. He concluded by challenging the Department of Higher Education and Training (DHET), saying its tendency to micromanage universities undermines the autonomy and leadership authority of institutional management.

 

A call to lead with intention

Reflecting on the impact of the event, Acting President of the Institutional Student Representative Council (ISRC) Mpho Maloka said, “These kinds of conversations are needed because they help us go back to the ‘why’ – why we became student leaders in the first place, and how we can serve students in ways that actually make a difference.”

She added, “People have turned student leadership into something so political that others don’t even want to get involved. Dialogues like this bring it back to what really matters – serving students and growing as ethical leaders.”

As Prof Klopper concluded: “The lessons in ethical and servant leadership that you learn and practise here prepare you not just for impactful careers, but for responsible citizenship in a world desperately in need of ethical leadership.”

Researcher part of project aimed at producing third-generation biofuels from microalgae in Germany

A researcher from the University of the Free State (UFS), Prof Johan Grobbelaar, was invited to join a group of scientists recently at the Institute for Bio- and Geo-Sciences of the Research Centre Jülich, in Germany, where microalgae are used for lipid (oil) production, and then converted to kerosene for the aviation industry.

The project is probably the first of its kind to address bio-fuel production from microalgae on such a large scale.  

“The potential of algae as a fuel source is undisputed, because it was these photoautotrophic micro-organisms that were fixing sunlight energy into lipids for millions of years, generating the petroleum reserves that modern human civilisation uses today.  However, these reserves are finite, so the challenge is marrying biology with technology to produce economically-competitive fuels without harming the environment and compromising our food security.  The fundamental ability that microalgae have to produce energy-rich biomass from CO2, nutrients, and sunlight through photosynthesis for biofuels, is commonly referred to as the Third-Generation Biofuels (3G),” said Prof Grobbelaar.

The key compounds used for bio-diesel and kerosene production are the lipids and, more particularly, the triacylglyserols commonly referred to as TAGs.  These lipids, once extracted, need to be trans-esterified for biodiesel, while a further “cracking” step is required to produce kerosene.  Microalgae can store energy as lipids and/or carbohydrates. However, for biofuels, microalgae with high TAG contents are required.  A number of such algae have been isolated, and lipid contents of up to 60% have been achieved.

According to Prof Grobbelaar, the challenge is large-scale, high-volume production, since it is easy to manipulate growth conditions in the laboratory for experimental purposes.  

The AUFWIND project (AUFWIND, a German term for up-current, or new impetus) in Germany consists of three different commercially-available photobioreactor types, which are being compared for lipid production.

The photobioreactors each occupies 500 m2 of land surface area, are situated next to one another, and can be monitored continuously.  The three systems are from Novagreen, IGV, and Phytolutions.  The Novagreen photobioreactor is housed in a glass house, and consist of interconnected vertical plastic tubes roughly 150 mm in diameter. The Phytolutions system is outdoors, and consists of curtains of vertical plastic tubes with a diameter of about 90 mm.  The most ambitious photobioreactor is from IGV, and consists of horizontally-layered nets housed in a plastic growth hall, where the algae are sprayed over the nets, and allowed to grow while dripping from one net to the next.

Prof Grobbelaar’s main task was to manipulate growth conditions in such a way that the microalgae converted their stored energy into lipids, and to establish protocols to run the various photobioreactors. This was accomplished in just over two months of intensive experimentation, and included modifications to the designs of the photobioreactors, the microalgal strain selection, and the replacement of the nutrient broth with a so-called balanced one.

Prof Grobbelaar has no illusions regarding the economic feasibility of the project.  However, with continued research, optimisation, and utilisation of waste resources, it is highly likely that the first long-haul flights using microalgal-derived kerosene will be possible in the not-too-distant future.

Prof Grobbelaar from the Department of Plant Sciences, although partly retired, still serves on the editorial boards of several journals. He is also involved with the examining of PhDs, many of them from abroad.  In addition, he assisted the Technology Innovation Agency of South Africa in the formulation of an algae-biotechnology and training centre.  “The chances are good that such a centre will be established in Upington, in the Northern Cape,” Prof Grobbelaar said.
