Opinion article by Prof Francis Petersen, Rector and Vice-Chancellor of the University of the Free State.
It is our harsh South African reality that racially charged incidents, such as the recent incident at Stellenbosch University, can happen at any institution at any time. Disheartening as they may be, they should not detract us from the very real journey towards true transformation and social cohesion that is taking place on South African campuses of higher education.

Along with all the various forms of change and transformation that different sectors in our country have undergone over the past few decades, there has also been a definite shift in the role of public universities. It has evolved from an almost exclusive focus on academics to a more society-focused role. An undeniable and very important part of universities’ mandate in modern-day South Africa is to make a positive difference in the communities we serve. This inevitably includes embracing transformation, inclusivity, and diversity. In short: universities must be microcosms of the kind of community that we want to see in the broader South African context.

Transformation in higher learning 

Since 1994, all university campuses have in one way or another implemented well-designed transformation processes and social cohesion programmes – reflected in their institutional culture, physical environment, and the Academic Project. What we should always bear in mind, though, is that transformation in its very essence can never be a complete process. It can never simply mean changing from one thing into something else, but it is rather an ever-continuing process that requires incessant focus and a resolute acceptance that you will never really arrive at a final destination. What this implies for universities is that – true to our nature – we should always challenge the status quo, question conventional wisdom, always wrestle with complex issues, and never settle. Only by doing this will we achieve perpetual renewal, which is what true transformation boils down to.

Over the years, there has been an important shift at traditionally white universities that runs much deeper than just a superficial change in numbers and racial composition. Black South Africans at these institutions have reached a critical mass, which means they can now more freely express their convictions about their individual lived experiences, and in the process assist in shaping the institutional culture in ways that recognise diversity. And often, certain events can act as triggers for them to express these lived experiences as a collective.

Trigger events that cause us to pause and reflect

In the past, transformation efforts at universities were centred around attempts to absorb, assimilate, and homogenise individuals into the dominant culture, instead of institutions shaping their institutional culture to adapt to their changing student population. The latter approach is far more effective and organic, requiring institutions to not only recognise and embrace diversification, but also to respond and adapt to it. Undesirable incidents or phenomena, whether in the form of acts of racism, gender-based violence, bullying, or any form of othering or intolerance then become triggers that should make us pause and reflect on where we are in our journey towards transformation, and whether we need to adapt in any area or in any way.  

I want to differ from observers who feel that the Stellenbosch urinating incident is not worth spending any time or discussion on. I believe it is vital that we understand these ‘triggers’, because it is in the process of grappling with it as a university society – in those sometimes-uncomfortable conversations that challenge us on so many levels – that true transformation occurs.  

Former trigger events at the UFS

A distressing trigger event in our own university’s history was in 2016, when white rugby spectators attacked a group of black protestors at the UFS. What made this particularly painful was that it happened almost a decade after the notorious Reitz video incident, when a racially offensive, humiliating student video made in response to the university’s residence integration policies at the time, surfaced. The Shimla Park incident was an immense disillusionment for the university leadership, as it flew in the face of the great strides made towards social cohesion in the preceding eight years. It was a stark reminder that transformation will always be a ‘moving towards’, as opposed to an ‘arrival at’. True transformation is a process that requires a constant listening to diverse student and staff voices from all angles, an unrelenting focus on visible leadership, constant interaction with the diverse groups that make up a campus community, which is then consistently translated into action and institutional reform. 

It also requires a continuous creation of spaces where students and staff can express themselves without fear. It is vital that platforms are created in different parts of an institution where diverse voices can be heard. And it is equally vital that we listen to these voices, and that intensive discourse be followed up with real action, ultimately shaping the institutional culture. It requires that we use these painful trigger events as moments to pause and reflect on our transformation journey. What is imperative, is that the entire institution should be involved in this reflection process – not only the policy drafters or those who specifically deal with social cohesion. 
 
Youth Month – an opportunity to assess involvement

Youth Month gives us the opportunity to consider just how well we are listening to the voices of young South Africans – specifically in our higher education sector. We need the youth to speak out, and to take up the positions that institutions of learning have created for student representation in their leadership structures as an important part of the transformation process. We also need them to respond in a very circumspect and mature way to the trigger events that challenge our transformational journey. They should expose and denounce them in no uncertain terms, but guard against triggering similar actions in the process, which will only lead to further polarisation and discord. Instead, they should treat trigger events as opportunities to pause and reflect on how they can become part of the journey towards solutions.

Trigger events don’t define individuals or institutions

There are numerous challenges facing universities countrywide: racism, gender-based violence, xenophobia, mental health challenges, intolerance, and many more. Try as we might, we cannot always prevent these challenges from ‘breaching our defences’.  And when they do, we need to draw on all sectors of our university community to come to terms with it as an institution and devise a strategy going forward. It is in this process that we make progress on our journey towards true social cohesion.

I recently came across this very apt description relating to mental health – which is one of those issues we need to continuously and openly address on our campuses:  

“Mental health problems don’t define who you are. They are something you experience. You walk in the rain and you feel the rain, but you are not the rain.” 

In the same way, trigger events that happen in our university spaces are issues that we have to deal with, talk about, address, and learn from. They are part of our students’ lived experience and should therefore shape our institutional journeys. But they do not define, limit, or reflect who and what we are. Or what we may become.

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.
