Commemorating World Mental Health Month 2023
The mental health of university students is of growing global concern.

One of the largest student mental health surveys in the world – initiated by Universities South Africa (USAf) in 2020 – found that up to 20% of university students in South Africa need mental health support. The research results also show that up to 77% of students with mental health disorders are not getting help. Contributing reasons include reluctance to seek help due to lingering stigma surrounding mental health, but also limited access. With growing demand and limited capacity, one-on-one therapy does not seem to be a sustainable solution. Some of the recommendations that stem from the report are to introduce a range of digitally based self-help interventions, to provide psychoeducation about when to access help, and to offer peer-to-peer support. This is precisely what the University of the Free State (UFS) Department of Student Counselling and Development (SCD) is now implementing. 

Coinciding with World Mental Health Awareness Month, SCD’s Road Map embodies a paradigm shift in student mental health support. “We want to capacitate students on their mental health journey. Following the Road Map, our students are now able to be active agents in their mental well-being,” says Dr Munita Dunn-Coetzee, SCD Director.

What exactly is this Road Map?

The SCD Road Map guides students to multiple sources of support. On the SCD website, students can delve into a wealth of self-help guides and toolkits that range from academic, emotional, and social well-being to personal challenges and psychological distress. In a commitment to expand the SCD reach beyond one-on-one sessions, the department is offering both in-person and online workshops and development programmes that can be accessed through Blackboard. Additionally, podcasts have been integrated into the SCD offerings to accommodate students' varying schedules and data constraints.

SCD has also partnered with the South African Depression and Anxiety Group (SADAG) to provide a 24/7 toll-free UFS Student Careline. The Careline can be reached in three ways: by calling 0800 00 6363, SMSing 43302, or emailing helpline@sadag.org. In a crisis, help is immediately activated, and assistance is sent to the student.

Another exciting aspect of SCD's Road Map¬ – which further integrates recommendations from the research report – is the shift from individual-centric interventions to group-based support. “We want to expand beyond individual therapy,” Dr Dunn-Coetzee says. “Although one-on-one therapy has an important place in mental health support, we are currently expanding to offer various support groups.” Through these circles of support, SCD aims to foster a culture of mutual learning, peer-to-peer connection, and collective well-being.

The Road Map therefore enables SCD to pivot toward a capacitating approach, equipping students to navigate their mental health journey in a truly collaborative model.

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.
