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.

Wildlife researcher in ground-breaking global research on giraffes

Capturing 51 giraffes without any injuries or mortalities to collect data that will contribute to the conservation of these animals is not for everyone. Capturing a giraffe with minimum risk to the animal and the people involved, requires extraordinary skill, planning, and teamwork. “This exercise is a dangerous task, since a well-placed kick from these large and extremely powerful animals can cause serious injuries. Early in October was the first time that giraffes were captured on such a large scale,” said wildlife researcher Dr Francois Deacon.

Dr Deacon from the Department of Animal, Wildlife and Grassland Sciences at the University of the Free State (UFS), led a multispecialist research group of over 30 people from 10 different countries to collect information about these little-known animals.

UFS first to collar giraffe
Taking a global approach, the team responsible for this intricate process consisted of wildlife biologists, conservationists, interdisciplinary scientists and five specialist veterinarians who are experienced in catching and working with wild animals. Specialised drugs sponsored by Dr Kobus Raath from Wildlife Pharmaceuticals, tested for the first time and administered with a dart gun were used to tranquillise the giraffe, which then allowed for the GPS collars to be fitted. These collars, sponsored by Africa Wildlife Tracking, enable the researchers to record the location of individual giraffe for up to two years, give 24/7 readings, irrespective of weather conditions. In this cost-effective manner, data can be gathered on climatic factors, giraffe communication, social behaviour, home ranges, seasonal movements, human and giraffe interaction zones, as well as migration routes and the duration of the migration process. The collars will effectively be used to locate individuals to collect faecal samples for hormonal cycles, stress hormones, nutrient deficiencies based on diet and also internal parasites.

“This knowledge we gain is the key to all keys in saving this iconic animal from becoming extinct,” said Dr Deacon.

Six years ago, during a pilot study, Dr Deacon was the first researcher to fit giraffes with a GPS collar. Collaring is less invasive and allows researchers to collect detailed samples. Not only was extensive knowledge and experience gained during the process, but he also initiated interest from the filmmaker and conservationist, Ashley Scott Davison, executive producer of Iniosante Inc.

Getting to tell the story
Davison, who was doing research for a film on giraffe learnt about the silent extinction of the species. In a great number of countries giraffe numbers have been declining by as much as 40% over only a few years since 2000. Today West Africa has between 400 to 600 giraffe left while four out of five giraffes were lost in East Africa since 2000. This is a considerable decline in numbers and poses a real threat to the survival of the species in the longer term. At the end of 2016, the giraffe was classified as vulnerable on the International Union for Conservation of Nature Red Data list.

According to Davison, children in school learn about the destruction caused by ivory poaching and habitat loss. But in Africa today, there are six times as many elephants as there are giraffes.

In the process to find out more about this majestic species Davison learnt of Dr Deacon’s work. After being introduced to and spending time with Dr Deacon, Davison not only describes the UFS as the leader in the conservation of giraffes but he returned to the university, three times to help build a dedicated research team to address unanswered research questions within various disciplines.

Flowing from the affiliation with the UFS is Iniosante’s award-winning production of a documentary, “Last of the Longnecks”. The film has received several awards, including official selection at the 2017 Global Peace Film Festival, the Wildlife Conservation Film Festival and the Environmental Film Festival in the US capital.

The film team accompanied the multispecialist research team last week to gather footage for a follow-up documentary, “Catching Giants”. This film is expected to air in middle 2018.
