The Centre for Gender and Africa Studies (CGAS) on the University of the Free State (UFS) Qwaqwa Campus recently hosted the Biennial Gendered Worlds Lecture. The series focuses on the meaning and interpretation of the social, cultural, and political environments where gender is constructed, experienced, and contested. The recent lecture featured a captivating address by Prof Vasu Reddy, the Deputy Vice-Chancellor: Research and Internationalisation. Titled The Taste(s) of Intimacies: Reflections on the Trifecta of Food, Sexuality and Love in Gendered Worlds, this lecture invited the audience to explore the complex, interconnected nature of these three domains.

Prof Reddy opened his talk by describing food, sexuality, and love as ‘grammars of intimacy’ – a powerful metaphor suggesting that these elements encode cultural scripts, regulate bodies, and create opportunities for resistance and transformation. He intentionally used the term ‘trifecta’, borrowed from horse racing, to highlight the synergistic yet sometimes incompatible relationship between these three elements. He explained that this trifecta provides a profound framework for understanding how intimacy is experienced, negotiated, and theorised within different cultural and gendered contexts.

The lecture was structured in several parts, beginning with a personal reflection on Prof Reddy’s upbringing. He shared an intimate image of himself and his grandmother, explaining how her kitchen was not just a domestic space for cooking and nurturing. He motivated that his grandmother’s kitchen was a site of ‘gendered and feminist pedagogy’. He described it as a space not just for nourishment, but also for learning. This is where he learned about nurturing and care through observation and storytelling. This personal anecdote set the stage for a broader discussion on the socio-political dimensions of food, which he described as a ‘mode of enquiry and practice’ and an ‘object of power’. He noted that food preparation is a form of gendered labour and highlighted how apartheid structured food along racial lines, turning dishes such as ‘chakalaka’ from symbols of struggle and survival into commodified examples for elite consumption.

Moving on to sexuality, Prof Reddy argued that, like food, it is a domain where intimacy meets regulation. He referenced the work of Zanele Muholi, a renowned visual activist, whose photography in projects such as Somnyama Ngonyama (‘Hail the dark lioness’) confronts histories of colonialism and gendered violence by asserting the visibility and dignity of black and queer bodies. This aspect of the lecture emphasised how sexuality is not merely personal but is deeply shaped by cultural and political scripts.

In another component of this lecture, Prof Reddy delved into the complex nature of love. He proposed that love, though often idealised as apolitical, is deeply structured by cultural norms and power relations. Drawing on the work of scholar Sara Ahmed, he described love as a ‘sticky emotion’ that adheres to certain bodies and relationships, shaping how people are nourished, touched, and recognised. He highlighted that love is often a struggle – a messy, unpredictable, and transformative process.

Prof Reddy also discussed the ‘affective dimension’ of these matters, explaining that emotions are not just personal feelings, but social forces that shape bodies, spaces, and politics. He linked this to the concept of ‘taste’, suggesting that it is not only a sensory experience, but also an affective one, laden with social context, pleasure, and sometimes shame.

Throughout the lecture, Prof Reddy emphasised the entanglement of the private and public realms, asserting that intimacy is not confined to the bedroom but is shaped by public politics and collective norms. He concluded by presenting resistance and liberation as central to the discussion, positing that food, sexuality, and love can be sites of radical acts. He cited bell hooks, who argued that intimacy can be a powerful force for healing and self-definition in the face of systemic oppression.

For Prof Reddy, gendered worlds are not just sites of oppression, but also spaces of possibility that prompt further questions to make sense of ourselves.

In his closing remarks, he invited the audience to consider the profound questions his lecture posed: What does intimacy taste like? Who gets to taste it? And how is that taste shaped by gender, power, and history? He encouraged everyone to critically engage with these questions – not just intellectually, but personally – to reimagine intimacy as a public, relational, and transformative practice for building a more equitable world.

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.
