Opinion article by Prof Sethulego Matebesi, Associate Professor and Head of the Department of Sociology, University of the Free State.


President Cyril Ramaphosa’s 2024 State of the Nation Address (SONA) has, as expected, drawn mixed reactions. The speech placed strong emphasis on addressing significant sources of discontent and division within the country, such as gender-based violence, unemployment, crime, load shedding, poor service delivery, and corruption. The speech underscored the President’s commitment to economic reform and job creation through initiatives such as the Presidential Youth Employment Intervention

At a time when South Africa is on the eve of national and provincial elections, where the youth hold immense potential to shape the outcome – if the registrations can translate into voting – it is interesting to note that the President’s approach of using the analogy of young ‘Tintswalo’ has drawn considerable debate.

‘Tintswalo’ and President Ramaphosa’s soft-line approach

While the President’s approach in utilising the positive life trajectory of Tintswalo – a young girl born in democratic South Africa – may have been intended to inspire hope and showcase progress for many since the end of apartheid, critics argue that it overlooks the persistent challenges that many young citizens still face. But is focusing on a single success story providing a misleading impression of the overall state of the nation and downplaying the continuous challenges South Africa faces?

Public opinion can vary, and different individuals and groups may have different perspectives on the nation’s current state. For many, the ANC-led government has created a nurturing environment through various policy interventions, and a system of social transfers geared towards sustainable and productive investment in citizens. This view was supported by the World Bank, which described the country’s policies and programmes for the poor as ‘effective, well-targeted, and providing sizeable benefits to the poorest households.’ 

Indeed, the post-apartheid environment and individual agency enabled today’s Tintswalos to prosper. These deliberate programmes and policy interventions provide an environment that fosters educational attainment, instils values, and encourages personal growth. However, it is important to acknowledge that not all young people have equal access to resources and opportunities.

President Ramaphosa did not appear harsh, but rather dignified in using political persuasion to convince the world of the government’s resolve to strive for equitable access to education, health care, and social services to ensure that all young people have a fair chance to prosper. 

And, of course, relying on political persuasion is not hard. 

The President, an advocate of the soft line approach, has perfected the art of smothering citizens with embraces – smothering that has lately been peppered with the phrase: ‘ba rata kapa ha ba rate (whether they like it or not), we have done well.’ He did not appear harsh each time he uttered this phrase, but dignified in the conviction of the achievements of the government he has been leading since February 2018. However, the effect of the Tintswalo analogy – accentuating the state’s weaknesses rather than obscuring them – is the opposite of what was intended.

The bottom line is that the number of unemployed, politically disengaged, and disgruntled youth is growing, as is their ferocity.

Shrinking fiscal resources and the central role of institutions

As South Africa achieves a significant 30-year milestone of political freedom, the protection of individual freedoms and the establishment of institutions to safeguard democratic values stand as noteworthy achievements. However, amid the celebrations, shrinking fiscal resources and the overarching impact of increasingly reduced budget cuts for the higher education sector will hamper the progress of a new generation of Tintswalos. It has repeatedly been proven that education is an essential pillar of a country’s economy.

In Why nations fail: The origins of power, prosperity and poverty, Acemoglu and Robinson underscore the significance of inclusive economic institutions. They argue that countries differ in their economic success because of their different institutions, the rules influencing how the economy works, and the incentives that motivate people. 

Consider for a moment the difference between teenagers in North and South Korea.

According to these scholars, those in the North grow up in poverty and know that they will not become prosperous due to the propaganda they are fed in school. Those in the South obtain a good education, with incentives encouraging entrepreneurial initiative and creativity.

In South Africa, one of the most disheartening anomalies of our nation’s state is the blatant failure to ensure consequential management for the recurring unauthorised, irregular, fruitless, and wasteful expenditure by municipalities and state institutions reported by the Auditor-General. This is indicative of political power that is exercised arbitrarily.

In steering its future development, a South Africa that embraces diversity, prioritises economic recovery, invests in education, and leverages the incentives provided by state institutions will ensure equitable access to services and opportunities and allow all young people a fair chance to prosper, regardless of political affiliation.

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.
