2019 is the year of the national general elections in South Africa – 8 May is when South Africans will have an opportunity to vote and to impact change, hopefully for the better.  But the beginning of 2019 saw the resurfacing of student protests, mainly driven by issues of registration, challenges associated with the National Student Financial Aid Scheme (NSFAS), student accommodation, safety of students (off-campus), insourcing, and various other issues influenced by local institutional context.
  
Challenges for university vice-chancellors

Our Constitution promotes protest, but emphasises the peaceful nature thereof, and that it should not infringe on the rights of others or damage property.  However, the protests experienced by the majority of higher-education institutions in South Africa in 2019 was exactly the opposite – disruption of classes, intimidation and victimisation, disrespect and often destruction of property.  A notion or approach of almost entitlement, even if the university management was willing to engage and was constantly open to assess ways and means to resolve these issues.  The drive for these protests was short-term gains, totally divorced from the long-term implications on the institution’s welfare.  This puts the university management under enormous pressure, sometimes feeling exposed and alone in ensuring that the institution remains sustainable – financially, as well as from an infrastructure and human resource perspective.

There is no doubt that the upcoming elections are used for political lobbying, tactical manoeuvring, and undermining to demonstrate political muscle – all playing out on our university campuses and to be managed by university vice-chancellors (VCs) and their executives.

Are universities not the pillars of knowledge in society, the providers of human capital and new knowledge to ‘lubricate’ our economy, the delivery of the next generation of professionals who will shape how our society, or a new South African citizenship should look like?  If this is the case, who are protecting our universities, who is standing with our VCs and university executives to ensure that our universities remain the beacon of hope for generations to come?  What is expected of VCs and university management in situations where there is a continual push for more, and if the response is not positive or immediate, protests, and in most instances violent and criminal behaviour. My personal view is not to securitise or militarise our campuses, but to resolve these issues through continuous engagement – but what if protests becomes violent and criminal?  What if disruptions challenge or threaten students, staff, infrastructure, and the academic project?  Student leaders seem to have forgotten the engagement with university leadership through a principle of ‘give and take’, always balancing short-term wins with the long-term sustainability and growth of the university.

Although universities often have their own internal disciplinary processes, these are slow, and the transgressors are often repeat offenders.  The sanctions are also in many cases restorative – which I believe it should, but to what end?

Help needed to ensure sustainability of universities 

We have seen how weak leadership, corrupt practices, and inadequate government funding have had a detrimental effect on the overall state of universities in the rest of the continent.  This has led to the outflow of excellent academics from the continent to elsewhere on the globe – a loss for the university and the continent!  Universities, although resilient, are also fragile as a system.  The protests associated with the #Rhodes and #FeesMustFall movements, together with the continued protests in 2019, run the risk of putting South African universities on a similar trajectory.  A fragile university system, when broken, will take decades to be restored.

Therefore, if universities are important institutions for society and the country, should there not be more concerted efforts from government and society to ensure that our universities remain strong and competitive? Although I do not offer a specific solution per se, should government, together with university leadership, staff, and students not be more vocal, thinking of a mechanism to curb and/or disallow immediate disruptions and the breakdown of infrastructure, and show visible support to university leadership in an effort to continue the academic project?  Our universities are performing extremely well against global counterparts, keeping in mind the current (and the past 10 years) South African economic growth and investment constraints with respect to infrastructure, research, and high-level scientific equipment – even a more critical argument to protect these national assets.

Academic project remains crucial

I am not for a moment belittling the issues raised by students and student leaderships – in fact, most, if not all of these issues, are legitimate.  I can understand the frustrations of the students – the slow pace of transformation, social integration, and often the lack of urgency in executing agreed decisions within the higher-education sector.  However, I am questioning the type of reaction or action exhibited by the students if, for similar legitimate reasons (through proper engagements), student demands cannot be completely met by university leaders.

In the final analysis, South Africa needs strong universities which are competitive – the country needs appropriate skills to enable and support the economy.  Also, universities need to listen to the student voice – deal with their concerns in a fair and socially-just manner; but as a sector with all its stakeholders, we need to ultimately respect the academic project and the infrastructure (physical and human) which support it.  We cannot afford party-political dynamics to ‘abuse’ the university campus in a way that can destroy the fibre of our higher-education system.  This will be catastrophic for South Africa, and I believe for the continent.

I call on government, voices in society, fellow students, student leadership, and staff to support university management openly, pro-actively and firmly, so that our universities remain places of intellectual engagement and discovery, places where different views are respected and heard, and by ‘jealously guarding’ the institutions as ‘country resources’, responding to all stakeholders’ concerns in a fair and just manner.

It is only then that universities ‘regain’ their rightful place in society, educating the next generation of scholars and professionals, advancing new knowledge, and purposefully disseminate and apply these to society – contributing to ‘lubricating the economy’ and to the betterment of the quality of life of our people!

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.
