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.”

“The aim of my project was to identify and characterise the contamination problem in an avocado-processing facility and then to find a solution,” said Dr Amy Strydom, postdoctoral fellow in the Department of Microbial Biochemical and Food Biotechnology at the University of the Free State (UFS).

Her PhD, “Control of Listeria monocytogenes in an Avocado-processing Facility”, aimed to identify and characterise the contamination problem in a facility where avocados were processed into guacamole. Dr Strydom completed her MSc in food science in 2009 at Stellenbosch University and this was the catalyst for her starting her PhD in microbiology in 2012 at the UFS. The research was conducted over a period of four years and she graduated in 2016. The research project was funded by the National Research Foundation.

The opportunity to work closely with the food industry further motivated Dr Strydom to conduct her research. The research has made a significant contribution to a food producer (avocado facility) that will sell products that are not contaminated with any pathogens. The public will then buy food that is safe for human consumption.


What is Listeria monocytogenes?

Listeria monocytogenes is a food-borne pathogenic bacterium. When a food product is contaminated with L. monocytogenes, it will not be altered in ways that are obvious to the consumer, such as taste and smell. When ingested, however, it can cause a wide range of illnesses in people with impaired immune systems. “Risk groups include newborn babies, the elderly, and people suffering from diseases that weaken their immune systems,” Dr Strydom said. The processing adjustments based on her findings resulted in decreased numbers of Listeria in the facility.

The bacteria can also survive and grow at refrigeration temperatures, making them dangerous food pathogens, organisms which can cause illnesses [in humans]. Dr Strydom worked closely with the facility and developed an in-house monitoring system by means of which the facility could test their products and the processing environment. She also evaluated bacteriophages as a biological control agent in the processing facility. Bacteriophages are viruses that can only infect specific strains of bacteria. Despite bacteriophage products specifically intended for the use of controlling L. monocytogenes being commercially available in the food industry, Dr Strydom found that only 26% of the L. monocytogenes population in the facility was destroyed by the ListexP100TM product. “I concluded that the genetic diversity of the bacteria in the facility was too high and that the bacteriophages could not be used as a control measure. However, there is much we do not understand about bacteriophages, and with a few adjustments, we might be able to use them in the food industry.”

Microbiological and molecular characterisation of L. monocytogenes

The bacteria were isolated and purified using basic microbiological culturing. Characterisation was done based on specific genes present in the bacterial genome. “I amplified these genes with polymerase chain reaction (PCR), using various primers targeting these specific genes,” Dr Strydom said. Some amplification results were analysed with a subsequent restriction digestion where the genes were cut in specific areas with enzymes to create fragments. The lengths of these fragments can be used to differentiate between strains. “I also compared the whole genomes of some of the bacterial strains.” The bacteriophages were then isolated from waste water samples at the facility using the isolated bacterial strains. “However, I was not able to isolate a bacteriophage that could infect the bacteria in the facility.
