Dr Tlou Raphela-Masuku, Senior Lecturer in the UFS Disaster Management Training and Education Centre for Africa (DiMTEC), was selected as one of 15 early-career researchers from Southern and Eastern Africa to join the British Academy-funded International Writing Workshop on Climate Change Adaptation.

Dr Tlou Raphela-Masuku, Senior Lecturer in the University of the Free State (UFS) Disaster Management Training and Education Centre for Africa (DiMTEC), has been selected as one of only 15 early-career researchers from Southern and Eastern Africa to participate in the prestigious British Academy-funded International Writing Workshop on Climate Change Adaptation.

Her selection follows a highly competitive process involving applicants from across the region, underscoring her growing influence in climate research. “Being selected as one of only 15 early-career researchers from the SADC and East Africa region was truly humbling. It affirmed the value of my research and passion for climate adaptation and further motivated me to keep making a meaningful contribution in this field,” she said.

 

Strengthening research visibility and collaboration

The workshop is jointly organised by York St John University (UK), the University of the West of England (UK), the University of Nairobi (Kenya), and the University of Cape Town (South Africa). It brings together emerging scholars from a range of disciplinary backgrounds to foster interdisciplinary collaboration, strengthen academic writing and publishing skills, and develop grant proposal expertise.

For Dr Raphela-Masuku, the programme is a natural fit with her work at DiMTEC. “At DiMTEC, my work spans ecosystem-based disaster risk reduction and climate change adaptation. I am the core teacher for this module for master’s students. My recent and upcoming research, including work on flood risks and climate vulnerability among subsistence farmers, directly aligns with the themes of the workshop,” she explained.

Her focus within the programme will be on climate-induced vulnerabilities and resilience, particularly in rural and peri-urban communities, with a strong emphasis on extreme weather events and nature-based solutions. She looks forward to both the online and in-person engagements in Nairobi and Cape Town, which will run between 2025 and 2027. “These offer a fantastic opportunity for peer learning, mentorship, and deeper engagement with fellow climate researchers. Exchanging ideas face to face is always energising and often leads to lasting collaborations,” she said.

 

Advancing DiMTEC’s mission

Participation in the workshop will not only advance Dr Raphela-Masuku’s own academic profile but also strengthen DiMTEC’s regional and continental footprint. “My participation directly supports DiMTEC’s mission to build climate resilience and disaster preparedness across Africa. It strengthens our footprint in the region and facilitates collaboration with other institutions working on similar challenges, especially in rural vulnerability and adaptation,” she noted.

She sees the experience as a vital platform to amplify her work on flood resilience and the health impacts of climate change to audiences that include academics, policymakers, and practitioners. “The workshop will enhance the visibility of my work and provide the tools and strategies to navigate high-impact publishing, which is crucial for emerging African scholars,” she added.

Reflecting on her journey, Dr Raphela-Masuku said it has been “rooted in both academic enquiry and real-world impact”, driven by the urgent need to support vulnerable communities. Her advice to aspiring researchers is clear: “Stay curious. Stay rooted in the needs of your communities. And don’t be afraid to ask hard questions or chase ambitious goals. Climate adaptation research is not just about publishing papers – it’s about finding real solutions for real people.”

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.
