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.”

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
