Sibongile Mdlala End of Gender-based Violence
Sibongile Madlala believes it is time to get every single South African involved in the fight to eradicate gender-based violence and not to look away or to stand on the side-line watching.

Sibongile Madlala, Crime Investigations Officer in Protection Services, believes it is time to get every single South African – especially boys and men – involved in the fight to eradicate gender-based violence and not to look away or to stand on the side-line watching.


“It is a time to observe that to date, gender-based violence awareness messages still promote the idea that it only affects women and children (girls) and to a certain extent ignores the plight of the LGBTIQ community, men and boys,” she says.

Report, do not keep quiet

It is time for the government and other relevant stakeholders to do everything possible to establish the root causes of GBV. She feels it is necessary to pay attention to and address matters such as mental health (of the offender and the victim/survivor), victim-offender overlap, patriarchal lines, and cultural practices that perpetuate gender inequalities.

“Government also need to observe the value of training officers of the law and the justice department, as it takes a special kind of person to deal and assist victims accordingly,” she says. 
 

Madlala is convinced that the criminal justice system needs to revisit the laws, policies, and systems that are dealing with gender-based violence-related matters, as it is failing the victims. “It is unfair to expect a victim to recount every single intimate detail in chronological order; it is also unfair to expect a minor or a mentally challenged person to stand in a box facing the perpetrator as they lead evidence over a lengthened period. The failure to implement child-friendly facilities is not acceptable,” she adds. 

“It is said that knowledge is power, and
I believe the sooner this pandemic is understood
by the victims, perpetrators, and handlers
— the sooner we will see some changes in this regard.”

Dealing with perpetrators

There is a National Sexual Offenders register in which the names of all prosecuted offenders are listed when they are found guilty. In dealing with perpetrators, she suggests a similar national offender register for gender-based violence offenders. “It is important that offenders are known, as those who need to protect are sometimes abusers themselves,” says Madlala.

The 16 days of activism is a time to let everybody know that gender-based violence is not a private matter. “It is said that knowledge is power, and I believe that the sooner this pandemic is understood by the victims, perpetrators, and handlers – the sooner we will see some changes in this regard.” 

She deems it important that victims are taught the importance of reporting and not protecting the abuser, and she emphasises the significance of ensuring that the voices of survivors, activists, and those mandated to address these matters at grassroots level are amplified and listened to.

Madlala sees this period as a celebration of survivors, the victors, heroes and heroines, young and old – especially those who have chosen to speak out about their traumatic experiences, knowing that the response may be negative.
 
“It is a time to commemorate all victims of gender-based violence and to raise awareness, stimulate advocacy efforts, and share knowledge on this topic,” she says.

It is time …

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.
