Opinion article by Dr Emmanuel Mayeza, a Senior Lecturer in the Department of Sociology, University of the Free State

On Monday 12 April 2021, Lufuno Mavhunga, a 15-year-old female learner at Mbilwi Secondary School in Limpopo, South Africa, was aggressively assaulted by another learner at school. The video showing the humiliating violent attack was circulated on various social media platforms. Sadly, Lufuno subsequently died as a result of suicide. During the bullying incident, bystanders (her school mates) watched, cheered, laughed, and recorded videos of the incident. The alleged perpetrator (another 14-year-old female learner at the same school) has since been arrested by the police and charged with assault. The school will institute disciplinary action against the bystanders who failed to assist and protect Lufuno. Lufuno’s family, however, believes that the school did not do enough to support Lufuno after the incident was reported to the school principal.

The victimisation of Lufuno could have been prevented, and I will show in this article what can be done to stop and prevent bullying in South African schools.

Suicide: the ultimate consequence of being bullied at school

Lufuno’s victimisation and her tragic death highlight the scourge, as well as the seriousness, of the problem of bullying in South African schools. School-based bullying has various consequences for everyone at school, but victims often incur the most devastation from bullying. The consequences of being bullied at school include the development of psychological and emotional problems such as distress, damaged self-esteem, anxiety, depression, and suicidal thoughts. If these problems are not addressed timeously or appropriately, it could ultimately result in suicide. Although Lufuno’s victimisation was reported to the school authorities, the deceased young victim did not receive any professional psychological counselling following the traumatic experiences of being bullied and the video of this incident being shared on social media. It seems that the victim dealt with the bullying mostly by herself and that the people who knew about the bullying did not take her ordeal and anxieties seriously enough.

Bullying is gendered and complex: Girls as victims and as bullies

Bullying is a form of gender violence. It is based on the asymmetrical relations of power that are prevalent in our patriarchal society. The key feature of such relations is men and boys assuming authority, domination, and control through violence against girls, women, and femininities. However, Lufuno’s victimisation draws our attention to the complexities of bullying and gender power relations among learners at school. Although boys and men often emerge as perpetrators of violence against girls and women, bullying in schools is a complex issue and girls are not always the passive victims of male violence.  Both girls and boys can become victims and bullies. Bullying is an expression of power, and girls too are capable of expressing power through forms of violence against other girls and against some boys. Indeed, a recent study on bullying among learners in a South African primary school highlights the vulnerability of younger boys to violence perpetrated by older girls at school ( https://doi.org/10.15700/saje.v41n1a1858 ). Therefore, we must acknowledge that the victimisation of Lufuno by another girl is not something unique. Gender relations are dynamic, and we can see that girls too have learnt how to use violence to express power and to claim dominance over other learners in schools.

What needs to be done to stop and prevent school-based bullying? 

While the processes of the criminal justice system regarding Lufuno’s victimisation are underway, effective prevention programmes are also required in order to stop bullying at school. Such programmes must be designed with the view to empower everyone at school with skills and knowledge on how to prevent bullying from happening, and how to react appropriately when bullying is witnessed or reported. To end bullying, the school should consider addressing bystanders, improving the availability of professional support services to victims of bullying, re-thinking the curriculum, and establishing stronger partnerships with other stakeholders.

All learners at the school must be addressed in terms of the roles that they can play as active bystanders who are committed to ending bullying. Bystanders must be empowered so that they know what bullying constitutes and are able to see when bullying happens and know how to intervene appropriately to stop it and protect the victim. They must know the seriousness of bullying and its consequences, and that this includes suicide. Bystanders must understand that posting a video or a photo on social media showing someone being abused is in itself also a form of bullying. Bystanders must be informed that they have a responsibility to report any form of bullying they witness at school to the school authorities or to their parents or guardians.

When learners have reported bullying, school authorities need to take the reported incident seriously and act appropriately, especially in terms of supporting the victim. To reduce the risk of victims committing suicide, professional psychological counselling support must be offered to the victims without delay. However, the risk of committing suicide among victims of bullying can only be significantly reduced if proper resources and victim support services are available at the school. The lack of such resources and services at Mbilwi Secondary School presents a major risk for victims to resort to suicide.  

The school should also explore possibilities of developing learning programmes that will foreground bullying and raise awareness about this serious issue. Such programmes should be compulsory for all learners and must be designed to encourage learners to speak out about their experiences, perceptions, and anxieties around bullying. Consequences of bullying and what needs to be done to stop and prevent school-based bullying should also form part of the topics for discussion within such learning programmes.

However, the school cannot be successful in its efforts towards ending bullying if it acts alone. The violent behaviour that learners demonstrate at school reflects, to a large extent, the normalised violence within households and communities. The school, therefore, must form strong partnerships with parents, communities, government, religious institutions, and other relevant stakeholders to explore effective ways of addressing bullying at school. The school must engage productively with these different stakeholders, and such engagements should also include learners’ voices and perspectives on the issue of bullying and how to end it.

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.
