The recent events in Senekal in the Eastern Free State have, for the umpteenth time, thrust the related issues of farm murders, racial tension, violent crime, and the responses of political leaders to these issues on the national agenda. The latest outrage was sparked by the murder of farm manager Brendin Horner. On Tuesday 6 October 2020, demonstrators – mostly white farmers – embarked on a violent protest at the Senekal Magistrates’ Court, following the appearance of two suspects for allegedly murdering Mr Horner. According to reports, a gunshot was fired, and a police vehicle was set on fire. 

In response, EFF leader Julius Malema called on his ‘ground forces’ to attend the Senekal trial of the murder accused, scheduled for 16 October 2020, to ‘defend’ state property and democracy. This response has generated a polarised reaction from the public, with some supporting this call, while others criticised Malema for inciting violence and racial division.

This drama is playing out while the country is still reeling from continuing incidents of gender-based violence and violence against children.

Violence in South Africa

This begs the question: Do we have a culture of violence in South Africa?

The concept of culture is often used (and misused) to refer to a range of different things. For some, culture refers to the observable distinctive traits of a particular group or collective, such as dress, food, or technology. For others, it refers to more abstract traits such as language, beliefs, or customs and traditions. For still others, culture refers to an appreciation for human expression in the form of art and music. Culture is all of these things, but it is also more than this. 

Anthropologically, culture is a central concept that helps us to make sense of human social dynamics and behaviour across all times and locations. As such, culture is seen as a complex system that both shapes, and is shaped by, humans within specific contexts. Culture thus has three key characteristics that concern us here. First, culture is shared. Second, culture is learned. Third, culture is symbolic.  

The question of whether or not we are in a culture of violence in South Africa raises further questions about whether we can, or should, speak of a culture of violence in the first place. What can we observe if we analyse this concept in relation to the three characteristics of culture outlined above?

Is violence shared?

As a country, we indeed share a history of violence. We share a history of multiple levels of violence, including structural, political, economic, social, and even cultural violence. We also share in the mass media consumption of violence, be it through movies, television, or even news reports of violence in our society. 

Is violence learned?

A culture survives over time because it is learned by successive generations. Values, beliefs, customs, practices, language, and many other symbols of culture are transferred from generation to generation through enculturation or socialisation. Experiences of violence, whether as perpetrators or victims or both, are inherited by successive generations. This is why we see many examples of history repeating itself in, for example, violent protests, or excessive force by police, or perceived violence inciting rhetoric. None of these are new, as there are various examples throughout our history as a country.   

Does violence have any symbolic significance?

What does violence mean in South African society? What is its symbolic value? Violence has become like a language. It is a form of communicating or expressing a range of negative emotions and attitudes, including anger, frustration, fear, anxiety, intolerance, and disrespect for basic human rights. It is still perceived by many as a valid symbol of resistance and may be justified on this basis. How often do we hear people involved in violent protests saying that “violence is the only language the government understands!” Thus, violence certainly has symbolic value in the South African historical and contemporary context. 

From the above, it could well be argued that, in terms of the three characteristics of culture, there indeed exists a culture of violence in South Africa. 

Addressing the culture of violence 

But what can we do about it?

Perhaps the best way to address the culture of violence, is to start with the successive generations. In any society, if you want to change the culture, you need to start with the youth. Cultural values are more easily shaped and adopted by the youth than by older generations who tend to be more rooted and set in their ways of thinking and behaving. If we want to change the culture of violence, we need to start changing the values, attitudes, and traits that may engender violence among the youth. These changing values then need to be enculturated among the youth in the hope that it will be internalised sufficiently to promote new ways of thinking and behaving.

How do we achieve this? By demonstrating proper leadership and by being the examples that we want our youth to become. We cannot expect to dismantle the culture of violence if we have leaders who, whether intentional or not, are perceived to be promoting the very values that encourage violence and anarchy. We need to demonstrate a willingness to use more productive and constructive ways to resolve differences or conflict, other than resorting to destruction of property or harming others. 

Lastly, it is imperative that we address the structural violence of an enduring social and economic system that continues to victimise and marginalise many. Culture and environment are interlinked. In order to change the culture of violence, we need to change the environment of violence.

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.
