Dr Lisa Rothmann, a plant disease epidemiologist from the University of the Free State (UFS) who was nominated in the TW Kambule-NSTF Award: Emerging Researcher category for this year’s NSTF-South32 Awards, says that the nomination is a reminder that service through science matters.

“I am humbled by the nomination. For me, it reflects not just individual recognition, but also the shared effort of the team of postgraduate academics, research assistants, partners, and farmers with whom I've had the privilege to work with. It is affirming to see plant pathology and field-based research recognised in this way; it highlights the consistent (hard) work we do to make a meaningful contribution to agriculture and to serve the grain industry and farmers,” says Dr Rothmann.

She was nominated by Grain South Africa (Grain SA), with whom she has been working closely since 2018 to contribute research that aligns with the organisation’s mission to strengthen the grain sector. They play a key role in supporting sustainable grain production and farmer development.

Dr Rothmann, who is one of eight UFS researchers and a research team nominated for the NSTF-South32 Awards – also known as the ‘Science Oscars’ – is nominated for her contribution to interdisciplinary, team-based research to develop practical solutions for plant diseases in order to protect crops and empower communities.

Motivation to keep growing

The Senior Lecturer in the Department of Plant Sciences within the Faculty of Natural and Agricultural Sciences (NAS) says that while she is proud of the work she has done, she sees this recognition as a team effort. Says Dr Rothmann: “It motivates me to keep growing as a researcher, rooted in impact and integrity. I’m not a prolific peer-reviewed publisher; my academic record includes 10 journal articles and one book chapter, but I have written around 50 popular articles – often as a solo author, in collaboration with postgraduates and peers.”

“These pieces translate plant pathology topics such as the Sclerotinia life cycle, disease surveillance, and management into accessible information for producers and the public. To me, this nomination is a symbol that making a meaningful impact doesn't only come from journal impact factors. This nomination has reminded me that building a career in academia is a relay, not a race, and that lasting impact comes from investing in others.”

As a plant disease epidemiologist, she specialises in field pathology – an area of plant pathology that explores how disease epidemics in crops develop, spread, and can be effectively managed within agricultural systems. Their work centres on understanding and managing Sclerotinia diseases in oilseed and protein crops such as canola, soybean, and sunflower, as well as disease surveillance in key grain crops including dry bean, sorghum, and sunflower.

New research

After participating in the US-based National Sclerotinia Initiative in 2017, she was inspired to establish a South African Sclerotinia Research Network with the support of Grain SA, creating a platform for researcher collaboration, farmer engagement, and the development of on-farm management strategies. Over time, explains Dr Rothmann, their research has expanded to include cultivar screening, national disease surveys, fungicide registration trials, and the development of disease-assessment tools. More recently, they have embedded sociological surveys into sorghum disease work to better understand farmers’ knowledge and needs, ensuring that research remains practical and co-created with producers.

According to Dr Rothmann, they have been privileged to work in a space that supports producers and protects crops through applied plant disease management strategies. While high-value crops often attract attention due to export markets, the grain that feed the nation forms the backbone of food security. As part of their new research, Dr Rothman and the research team are currently contributing to the Sorghum Cluster Initiative's pre-breeding programme, where they have screened 160 accessions for diseases to support future cultivar development.

They are also going to explore how both emerging and commercial farmers will adopt these new cultivars. She is actively seeking collaborators in sociology/psychology or similar fields to better understand farmers’ decision-making. They are developing a plant disease dashboard to map disease occurrences across South Africa – an effort aligned with the Plant Health (Phytosanitary) Act 35 of 2024 to help guide appropriate disease risk categorisation. In the long term, concludes Dr Rothmann, they hope to establish a diagnostic hub for central South Africa in partnership with Agricultural Research Council-Grain Crops to strengthen local disease identification and support producers in real time.

A great honour was bestowed on a researcher at the University of the Free State (UFS) when he was invited to the preview of the documentary film, Last of the Longnecks. Dr Francois Deacon, lecturer and researcher in the Department of Animal, Wildlife and Grassland Sciences at the UFS, who also has a role in the film, attended the preview at the Carnegie Institution for Science’s Smithsonian National Museum in Washington DC, in the US, in March this year. The preview formed part of the DC Environmental Film Festival.

The Environmental Film Festival in the US capital is the world’s leading showcase of films with an environmental theme and which aims to improve the public’s understanding of the environment through the power of film. During the festival, the largest such festival in the US, more than 150 films were shown to an audience of 30 000 plus.

Dr Deacon was invited by the producer of Last of the Longnecks to be part of a panel handling a question-and-answer-session about the film directly after the show. He described it as the greatest moment of his life.

Role in the film Last of the Longnecks

“My role in the film was as the researcher studying giraffes in their natural habitat in order to understand them better, so that we may better protect them, and be able to provide better education on the problem in Africa,” says Dr Deacon.

“Together with Prof Nico Smit, also from the UFS Department of Animal, Wildlife and Grassland Sciences, Hennie Butler from the Department of Zoology, and Martin Haupt from Africa Wildlife Tracking, we were the first researchers in the world to equip giraffes with GPS collars and to conduct research on this initiative,” he says. This ground-breaking research has attracted international media attention to Dr Deacon and Prof Smit.

“Satellite tracking is proving to be extremely valuable in the wildlife environment. The unit is based on a mobile global two-way communication platform, utilising two-way data satellite communication, complete with GPS systems.

“It allows us to track animals day and night, while we monitor their movements remotely from a computer over a period of a few years. These systems make the efficient control and monitoring of wildlife in all weather conditions and in near-to-real time possible. We can even communicate with the animals, calling up their positions or changing the tracking schedules,” says Dr Deacon.

The collars, which have been designed to follow giraffes, enable researchers to obtain and apply highly accurate data in order to conduct research. Data can be analysed to determine territory, distribution or habitat preference for any particular species.

Over a period of three years (2014-2016), the Last of the Longnecks team from Iniosante LLC captured on film how Dr Deacon and his team used the GPS collars in Africa to collect data and conduct research on the animals.

“With our research, which aims to understand why giraffes are becoming extinct in Africa, we are looking at the animal in its habitat but not only the animal on its own. If the habitat of these animals is lost, they will be lost as well. Therefore, our focus is on conservation and better understanding the habitat. The giraffe is only a tool to better understand the habitat problem,” says Dr Deacon.

Since the beginning of his research Dr Deacon and his team have had six new collar designs, with animals in four different reserves being equipped with the collars. The collars use the best technology available in the world and make it possible to determine how giraffes communicate over long distances, and how their sleep patterns function. Physiological and biological focus is placed on the giraffe’s stress levels, natural hormone cycles, and milk quality in cows.

Experience at the film festival

“Absolutely amazing. Totally beyond our frame of reference as South Africans.” This is how Dr Deacon describes his experience of the three days in Washington DC during the film festival.

“It was an absolute honour to be part of the global preview of the film and to be able to work with Ashley Davison, the director of the film, and his team. I am just a rural farm boy who dreams big, and now this dream is known worldwide!” he says.

The film, which will be launched in April, will be screened in South Africa on the National Geographic channel in May 2017. Meanwhile, the film will also be shown at eight other film festivals in the US.

Work will start on a follow-up documentary in October and Dr Deacon is excited about the prospect. A mobile X-ray machine will be available from October. Internal sonars could also be performed on each of the animals. Researchers from around the world will form part of the team which will be led and co-ordinated by Dr Deacon and his co-workers at the UFS.
