Prof Melanie Walker and keynote speaker, Prof Narend Baijnath, who reflected on his own academic path to instil a sense of pride in the newer generation of academics.

The Higher Education and Human Development Research Group is one of the prestige research groups at the University of the Free State (UFS). The group, under the stewardship of Prof Melanie Walker, A1 NRF-rated researcher, brings together researchers, PhD students, and postdoctoral fellows who focus on human development and capability studies in the higher education space.

A colloquium that took place recently (25 August 2021), celebrated the conclusion of research projects such as the Miratho project, and also reflected on the achievements of 2020 and 2021 in challenging COVID-19 times. Most importantly, the group celebrated the five PhD graduates of 2021. 

Prof Narend Baijnath, Chairman of the Board of Governors of the Commonwealth of Learning, was the keynote speaker at the celebratory colloquium.

Lessons from Prof Baijnath 

Although in the ‘twilight of his career’, Prof Baijnath used his keynote address to share and reflect on his own journey to guide academics and postdoctoral fellows embarking on their new journeys. “Looking back, while I do acknowledge that adversity and struggle may build character and fuel perseverance, it is often the largesse and generosity of others that makes the difference between whether you realise your full potential or not,” Prof Baijnath said.  “Local community members pitched in to cover my own university fees and the cost of books when times were tough, and never asked to be repaid,” he remembered. 
 
However, it was also the support his mother gave him, because “she valued education above all else”.  “She made sure that my needs were provided for as a priority before attending to other needs of the family,” he said.  
 
Prof Baijnath, through his own circumstances, resonates with young people at universities today, because getting through university is a daily challenge for many of our youth who are desperate to escape poverty and fulfil their dreams. “They bristle with potential, are hardworking and focused, and hungry for success. Even though many more funding opportunities exist today that were non-existent back then, the struggle to escape poverty and disadvantage persists for many,” he said.

PhD students and graduates invaluable 

The five PhD graduates are Dr Berth Kibona; Dr Fenella Sommerville, Dr Martino Mazinga; Dr Monique Kwachou Tangah; and Dr Ndakaitei Manase. “It is a mighty achievement to reach this milestone. Only those who have completed the journey or who are currently embarked upon it will fully understand the momentousness of this occasion,” Prof Baijnath said in his remarks.  

Of the current group of PhDs, all draw on the capability and human development approach – each with a with different focus: access to higher education in Zambia; alternative post-school pathways in Malawi; student activism and social media in South Africa (SA); climate justice and the role of universities in Malawi, decolonising higher education in SA; and architecture and human development. “Our PhDs are so important in the life of our research group,” Prof Walker emphasised.

Research output contributes to prestige 

The event further celebrated the publication of books, such as the Miratho project book due for publication later this year, which examines the opportunities, obstacles, and outcomes for low-income youth and higher education. In addition, there is the forthcoming 2021 book by Dr Carmen Martinez-Vargas on participatory research, and Prof Walker’s 2020 edited book on epistemic justice. This is in addition to a steady stream of peer-reviewed articles in international journals and book chapters.

The awarding of international grants and research opportunities embodies the empirical success of the group. Senior researcher Dr Faith Mkwananzi serves as the chief investigator on a research project with the Open University and Coventry University. Funding for the project is through the British Academy (BA). Another project undertaken by Dr Mkwananzi is the Changing the Story project, which is also funded by the BA.  “All this funding will allow very exciting projects to go ahead and further strengthen our contributions to Global South research,” said Prof Walker. The group also welcomed a new research associate from Lancaster University, Dr Melis Cin. Dr Cin is the successful recipient of a large grant for decolonising peace education in Africa.

Overall, research projects undertaken by members exemplify a commitment to rigorous and original South-based research and to social justice through advancing human development and expanding people’s freedoms.

Several industries in South Africa are currently producing hundreds of thousands of tons of carbon dioxide a year, which are released directly into the air. A typical family sedan doing around 10 000 km per year, is annually releasing more than one ton of carbon dioxide into the atmosphere.

The Inorganic Chemistry Research Group in the Department of Chemistry at the University of the Free State (UFS), in collaboration with the University of Zurich in Switzerland, has focused in recent years on using carbon dioxide – which is regarded as a harmful and global warming gas – in a meaningful way. 

According to Prof André Roodt, Head of Inorganic Chemistry at the UFS, the Department of Chemistry has for the past five decades been researching natural products that could be extracted from plants. These products are manufactured by plants through photosynthesis, in other words the utilisation of sunlight and carbon dioxide, nitrogen, and other nutrients from the soil.

Caffeine and chlorophyll 
“The Inorganic group is systematically researching the utilisation of carbon dioxide. Carbon dioxide is absorbed by plants through chlorophyll and used to make interesting and valuable compounds and sugars, which in turn could be used for the production of important new medicines,” says Prof Roodt.

Caffeine, a major energy enhancer, is also manufactured through photosynthesis in plants. It is commonly found in tea and coffee, but also (artificially added) in energy drinks. Because caffeine is a stimulant of the central nervous system and reduces fatigue and drowsiness, some people prefer decaffeinated coffee when enjoying this hot drink late at night. 

Removing caffeine from coffee could be expensive and time-consuming, but also environmentally unfriendly, because it involves the use of harmful and flammable liquids. Some of the Inorganic Group’s research focus areas include the use of carbon dioxide for the extraction of compounds, such as caffeine from plants. 

“Therefore, the research could lead to the availability of more decaffeinated coffee products. Although decaffeinated coffee is currently aromatic, we want to investigate further to ensure better quality flavours,” says Prof Roodt.

Another research aspect the team is focusing on is the use of carbon dioxide to extract chlorophyll from plants which have medicinal properties themselves. Chemical suppliers sell chlorophyll at R3 000 a gram. “In the process of investigating chlorophyll, our group discovered simpler techniques to comfortably extract larger quantities from green vegetables and other plants,” says Prof Roodt.

Medicines
In addition, the Inorganic Research Group is also looking to use carbon dioxide as a building block for more valuable compounds. Some of these compounds will be used in the Inorganic Group’s research focus on radiopharmaceutical products for the identification and possibly even the treatment of diseases such as certain cancers, tuberculosis, and malaria.
