In terms of gender violence, Dr Ana Stevenson says change has only occurred because of the willingness of some, especially feminist activists, to take a stand against community complacency. Pictured here, she speaks about the book in Rockhampton, Queensland, Australia.

“Gender violence has gained renewed public visibility in South Africa over the past weeks due to the horrific murder of undergraduate womxn (the term/spelling used by activists during the recent marches) from the University of Cape Town and the University of the Western Cape. These tragedies followed the longer history of high-profile cases of gender-based violence, where violated young womxn become the focus of intense media analysis – sometimes sympathetic, but often characterised by victim blaming.” 

These are the words of Dr Ana Stevenson, postdoctoral research fellow in the International Studies Group in the Faculty of the Humanities at the University of the Free State (UFS).

She believes that most media commentary and policymaking are rarely contextualised in terms of the long history of gender violence. A recent edited collection, Gender Violence in Australia: Historical Perspectives (Monash University Publishing, 2019), which she co-edited with her colleague, Dr Alana Piper (University of Technology Sydney), seeks to bring historical context to contemporary discussions about gender violence.

Dr Stevenson, an Australian historian of social movements, joined the International Studies Group in 2016. With her research, she examines the lives and writings of activist women in feminist and anti-racist social movements in South Africa as well as in Australia and the United States. 

She considers herself fortunate to have been offered the opportunity to live and work in South Africa during this era of student activism on campuses across the country.

Words alone are not enough

Other South African scholars have turned their attention to gender violence in recent years. Rape and other forms of sexual violence are chronically underreported in South Africa, a problem that also exists in other national contexts. Victims simply do not feel safe enough to report their experiences to the police, says Prof Pumla Dineo Gqola, author of Rape: A South African Nightmare (Jacana Media, 2015).

Dr Stevenson adds: “Despite public outcry, the emergence of new victims suggests that the cultural shifts which are needed to transform the violent behaviours that disproportionately affect the lives of womxn, have sadly not been achieved. The marches in solidarity across many university campuses, including at the UFS, are certainly a step in the right direction, as is the UFS’s renewed commitment to eradicating all forms of gender-based violence.”

However, according to her edited collection, words alone are not enough. 

She believes that greater public awareness can only help to address the problem to a degree. “What is needed in addition to initiatives that seek to effect cultural and behavioural change among perpetrators, is ongoing and dedicated funding for rape crisis centres and other support services for those who encounter gender violence,” Dr Stevenson says.Book cover

Taking a stand against complacency

Gender Violence in Australia indicates exactly where violent behaviours come from and seeks to illustrate how they have been rationalised over time. “It is important to recognise that change has only occurred because of the willingness of some, most especially feminist activists, to take a stand against community complacency. We hope that, in identifying these patterns over a period of more than 150 years, our collection will be useful for policymakers, politicians, and the media, as histories of violence are intimately connected to understanding how gender violence operates in the present.”    

“Our collection hopes to make the important first steps in assembling a history that builds on the work of feminist historians, whose earlier research about gender violence in Australia examined the phenomenon in various contexts. In doing so, we bring together the analysis of domestic, family, sexual, institutional, economic, psychological, structural, and state violence to identify the important links between historical legacies and the contemporary moment. Making the connections between past and present explicit, offers the opportunity to track the changes and continuities that shape our understanding of gender violence today.”

Dr Stevenson strongly believes that womxn are not to blame, and that they must keep raising their voices to make themselves heard. She supports Prof Gqola, who said: “A future free of rape and violence is one we deserve, and one we must create.”

• Womxn: According to the Urban Dictionary, it is a spelling of ‘women’ which is a more inclusive, progressive term that not only sheds light on the prejudice, discrimination, and institutional barriers womxn have faced, but to also show that womxn are not the extension of men but their own free and separate entities.

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.
