Dr Lucia Meko believes that face-to-face engagement helps students become more empathetic, culturally aware health professionals.

In South Africa, the streets often tell stories of contrasts where wealth and poverty, tradition and modernity, and diverse cultures meet at the same intersection. It is a place where neighbours may speak different languages, worship in different ways, and sit down to very different meals. These everyday differences do not just influence how people live – they shape what ends up on their plates.

According to Dr Lucia Meko, Senior Lecturer and Head of the Department of Nutrition and Dietetics at the University of the Free State (UFS), dietitians play an important role in such a diverse landscape. “Their mission is to empower individuals and communities to make informed, healthy food choices that support long-term well-being. According to the Health Professions Council of South Africa (HPCSA), dietitians are trained to provide personalised nutrition counselling aimed at preventing and managing diet-related diseases,” she says.

“This means that whether someone is dealing with diabetes, high blood pressure, or simply trying to improve their eating habits, a dietitian can offer guidance tailored to their unique needs and circumstances.”

However, Dr Meko believes that while theory is important, many students only truly understand the reality of their future clients when they experience it first-hand. At the UFS, students do not have to wait until the end of their degrees to gain this insight. Community service learning begins in their very first year.

This approach immerses students in the communities they will eventually serve, offering a practical education that goes beyond textbooks. By working directly with communities, students gain a deeper appreciation of the challenges individuals face in making healthy food choices,” she says.

“These experiences help shape well-rounded professionals who are not only knowledgeable but also empathetic and culturally aware,” adds Dr Meko.

Unlike traditional volunteering, this is structured learning with clear outcomes. Students apply classroom theory to real-world issues while simultaneously giving back. Through this process, students develop critical thinking, cultural competence, and the ability to communicate health information in ways that are relevant and respectful,” she explains.

 

What really happens on the ground

To understand what this looks like in practice, Dr Meko points to a research study conducted by the department. It examines the experiences of fourth-year students during a Community Nutrition Module internship. This internship is one of eight work-integrated learning (WIL) components in the module.

In this particular placement, students work in Ward 51 in Mangaung, visiting homes and engaging directly with residents. During each visit, they profile the community member’s demographics, measure nutritional status (using weight and height), and assess dietary patterns. Afterward, they offer tailored dietary counselling.

Beyond individual visits, students also explore the broader food environment: visiting supermarkets, vegetable gardens, early childhood centres, and street vendors all form part of their learning.

Importantly, this programme is not one-sided. Feedback from both students and community members is gathered to improve the experience and assess its impact.

So far, early findings are promising. Students not only learned; they were transformed. Interestingly, students mostly showed appreciation for their own privileges in comparison to the disadvantaged communities they visited,” says Dr Meko. One student reflected: “It humbled me and made me very grateful for all that I have, because I think we really lose sight of that sometimes.”

After a township tour, another student admitted: This was very insightful, as we often have stereotypes about the way people live and what people eat, simply because of where they live.”

In a cooking activity, students were challenged to apply dietary guidelines in real kitchens. The outcome? A deeper understanding of the barriers faced by many. “Dietetic guidelines we have given to some patients were really put into perspective, as cooking with less salt is not as easy as we think,” says Dr Meko, quoting student feedback.

Some even used what they learned in other placements. One student took a simple grocery list she developed during her internship to the hospital setting: “It is the most practical way to influence someone to shop differently.”

Others were inspired to continue working in food access. “I was impressed with the size of the vegetable gardens and was also inspired to be part of projects like these in the future,” shared another student.

Perhaps one of the most powerful observations came from a student who said: “I feel empowered but also sad to see that this is how most of the country is living and that we can make a difference, no matter how small.”

 

A lasting impact for both student and community

For Dr Meko, this is exactly what service learning should achieve. “While lectures and textbooks can teach the theory behind intercultural competence, it’s the face-to-face interactions – listening to people’s stories, understanding their struggles, and working alongside them – that truly bring those lessons to life.”

She adds that this kind of learning also builds stronger, more respectful relationships between the university and the communities it serves. “It fosters partnerships built on mutual respect, shared goals, and the exchange of knowledge and resources – locally and beyond.”

Community service learning is not just a tick-box exercise. In the UFS Department of Nutrition and Dietetics, it is a meaningful bridge between knowledge and empathy, between theory and reality, and – most importantly – between future dietitians and the people whose lives they hope to improve.

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.
