Research Chairs 2024
Prof Paul Oberholster, Dean: NAS; Dr Glen Taylor, Senior Director for the Directorate Research Development (DRD); Prof Vasu Reddy, Deputy Vice-Chancellor, Research and Internationalisation; and Prof Johan van Niekerk, Vice-Dean for Agriculture in the Faculty of Natural and Agricultural Sciences (NAS); are excited for the new ARC-DALLRD-UFS research chairs.

In a concerted effort to address the challenges and impact of climate change in Southern Africa, the University of the Free State (UFS) together with the Agricultural Research Council (ARC) and the Department of Agriculture, Land Reform and Rural Development (DALRRD) established four new research chairs within the Faculty of Natural and Agricultural Sciences (NAS).

The ARC-DALLRD-UFS research chairs, namely Climate Change and Agriculture, Innovative Agro-processing for Climate-smart Food System, Agriculture Risk Financing and Sustainable Livestock Production, falls under the umbrella of climate change and are part of the established centre of excellence of the ARC and DALRRD on Climate Smart Agriculture.

They will form part of two centres of excellence that the university is also in the process of establishing. The framework for these Agriculture Research Centres of Excellence involves several key components aimed at fostering innovation, collaboration, and impactful research in agriculture. In this case it is Climate Smart Agriculture, enabling them to play a pivotal role in advancing agriculture, enhancing productivity, sustainability, and resilience in the face of global challenges related to climate change.

Prof Johan van Niekerk, Vice-Dean for Agriculture for NAS, and Prof Sonja Venter, from the ARC, are the coordinators for the ARC-UFS-consortium. Joel Mamabolo from the DALRRD is the department’s representative and DALRRD manager in the consortium.

The purpose of the research chairs, he explains, is to conduct high-level research with an aspect of community impact as envisaged in the university’s vision 130. This is the UFS and NAS’s first steps towards creating industry chairs with negotiations between the UFS and the ARC-DALRRD currently taking place for further expansion of the chairs.

Improve research and food security

“The UFS has a long-standing relationship with the ARC and the parties came together to work together to improve research and food security in South Africa and Sub-Saharan Africa. The best way to do this, was by creating research chairs. The ARC saw the university’s expertise in agriculture which also contributed to the ARC establishing the chairs. Our expertise is of such a nature that it does not only influence the sector, but also makes a lasting difference,” says Prof Van Niekerk.

According to him, the ARC and the UFS will collectively manage the research chairs by appointing co-chair principal scientists for each of the chairs in order for the chairs to work together and share resources and expertise. The ARC-DALLRD-UFS research chairs will also work closely together within multidisciplinary research teams and complement each other and in doing so, create a value chain within the agriculture sector.

It will integrate various disciplines including agronomy, genetics, soil science, ecology, pathology economics, socioeconomics horticulture, animal sciences, food sciences and engineering to mention a few. This multidisciplinary approach will foster comprehensive research solutions and innovation at the intersection of different fields and will aim to contribute to sustainable food systems for the future.

The first two chairs; Climate Change and Agriculture, headed by Prof Linus Franke, Head of the UFS Department of Soil, Crop, and Climate Sciences, and the Innovative Agro-processing for Climate-smart Food System, which will be under Dr Alba du Toit, Senior Lecturer in the Department of Sustainable Food Systems and Development, officially started on 1 July 2024, while the remaining two chairs will begin operating in December. The ARC will soon confirm the co-leaders of the various chairs.

The Agriculture Risk Financing research chair will be shared between the Department of Agricultural Economics, within NAS, and the UFS Business School. The Sustainable Livestock Production chair will fall within Prof Frikkie Neser’s Department of Animal Science. To add more credibility, experience and expertise to the ARC-DALLRD-UFS research chairs, Prof Maryke Labuschagne, who is leading the NRF SARChI Chair in Diseases and Quality of Field Crops, has been appointed as mentor.

Prof Vasu Reddy, Deputy Vice-Chancellor, Research and Internationalisation, says: “These chairs mark an exciting opportunity to deepen our understanding of climate change aligned to our expertise in agriculture. The chairs offer us the opportunity to honour and support the leaders who will contribute in powerful ways to the vibrant intellectual life of the faculty, as well as the university, the ARC and DALRRD.

“The chairs also honour the donor whose financial support makes this form of recognition possible. At the UFS we are committed to engaging in global challenges but with a deliberate local focus, energy and drive. I am especially excited that these chairs demonstrate a commitment to the UFS focus on partnerships with industry, communities, the state and other academic and research institutions both nationally and around the world.”

Grateful for the ARC relationship

Through these chairs more collaborators and partners from other universities in the country and globally will be included in the partnership with the aim to bring together internationally renowned scientific experts that will collectively focus to address global challenges and enhance the development of more scientific capacity for the country.

The university, Prof Van Niekerk continues, is grateful for the cooperation and relationship with the ARC and its President and CEO, Dr Litha Magingxa and the executive management team, as well as the DALRRD DG, Mooketsa Ramasodi and the DDG for Agricultural Production, Biosecurity and Natural Resources Management, Dipepeneneng Serage for creating an environment within which the Universities and ARC can collectively contribute towards developing solutions with the DALRRD for key agricultural challenges of the country.

He expressed his gratitude to the Directorate Research Development (DRD) under the leadership of Dr Glen Taylor, for not only their support, but for bringing the parties together and negotiating with the ARC on their behalf. In this regard he wishes to thank Dr Petronella Chaminuka from the ARC as the acting Executive Manager: Research support and coordination for her support, guidance and leadership during the process.

Prof Van Niekerk also thanked Profs Francis Petersen, UFS Vice-Chancellor and Principal, Reddy, and Paul Oberholster, Dean of the Faculty of NAS, for creating the environment and rendering immense support for this programme from the UFS.

Studies to reveal correlation between terrain, energy use, and giraffe locomotion
2016-11-18



More than half of giraffes in captivity in Europe are afflicted by lameness. This high prevalence represents an important welfare issue, similar to other large zoo animals.

According to Dr Chris Basu, a veterinarian at the Royal Veterinary College in the UK, giraffes in captivity are often afflicted by overgrown hooves, laminitis and joint problems. Diagnosis and treatment is limited by our understanding of anatomy and function, more specifically the locomotion of these animals. Although the giraffe is such a well-known and iconic animal, relatively little has been studied about their locomotor behaviour.

Dr Basu recently visited South Africa to do fieldwork on the locomotion of giraffes as part of his PhD studies under the mentorship of world-renowned Professor of Evolutionary Biomechanics, Prof John Hutchinson. This project is a joint venture between Dr Basu and Dr Francois Deacon, researcher in the Department of Animal, Wildlife, and Grassland Sciences at the UFS. Dr Deacon is a specialist in giraffe habitat-related research. 

Together Prof Hutchinson and Drs Deacon and Basu form a research group, working on studies about giraffe locomotion.

Wild giraffe population decrease by 40% in past decade

“Locomotion is one of the most common animal behaviours and comes with a significant daily energetic cost. Studying locomotion of wild animals aids us in making estimates of this energetic cost. Such estimates are useful in understanding how giraffes fit into ecosystems. Future conservation efforts will be influenced by knowledge of the energy demands in giraffes.

“Understanding aspects of giraffe locomotion also helps us to understand the relationships between anatomy, function and evolution. This is relevant to our basic understanding of the natural world, as well as to conservation and veterinary issues,” said Dr Deacon.

Locomotion study brings strategy for specialist foot care

On face value it seems as if foot disease pathologies are more common in zoo giraffes than in wild giraffes. “However, we need a good sample of data from both populations to prove this assumption,” said Dr Basu. 

This phenomenon is not well understood at the moment, but it’s thought that diet, substrate (e.g. concrete, straw, sand and grass) and genetics play a part in foot disease in giraffes. “Understanding how the feet are mechanically loaded during common activities (standing, walking, running) gives our research group ideas of where the highest strains occur, and later how these can be reduced through corrective foot trimming,” said Dr Basu.

Through the studies on giraffe locomotion, the research group plans to devise strategies for corrective foot trimming. At the moment, foot trimming is done with the best evidence available, which is extrapolation from closely related animals such as cattle. “But we know that giraffes’ specialist anatomy will likely demand specialist foot care,” Dr Basu said.

Studying giraffes in smaller versus larger spaces

The research group has begun to study the biomechanics of giraffe walking by looking at the kinematics (the movement) and the kinetics (the forces involved in movement) during walking strides. For this he studied adult giraffes at three zoological parks in the UK. 

However, due to the close proximity of fencing and buildings, it is not practical to study fast speeds in a zoo setting. 

A setting such as the Willem Pretorius Nature Reserve, near Ventersburg in the Free State, Kwaggafontein Nature Reserve, near Colesberg in the Karoo, and the Woodland Hills Wildlife Estate in Bloemfontein are all ideal for studying crucial aspects such as “faster than walking” speeds and gaits to measure key parameters (such as stride length, step frequency and stride duration). These studies are important to understand how giraffe form and function are adapted to their full range of locomotor behaviours. It also helps to comprehend the limits on athletic capacity in giraffes and how these compare to other animals. 

Drones open up unique opportunities for studying giraffes

The increasing availability of unmanned aerial vehicles (UAVs)/drones opens up unique opportunities for studying locomotion in animals like giraffes. Cameras mounted onto remotely controlled UAVs are a straightforward way to obtain high-quality video footage of giraffes while they run at different speeds.

“Using two UAVs, we have collected high definition slow motion video footage of galloping giraffes from three locations in the Free State. We have also collected detailed information about the terrain that the giraffes walked and ran across. From this we have created 3D maps of the ground. These maps will be used to examine the preferred terrain types for giraffes, and to see how different terrains affect their locomotion and energy use,” said Dr Deacon.

“The raw data (videos) will be digitised to obtain the stride parameters and limb angles of the animals. Later this will be combined with anatomical data and an estimation of limb forces to estimate the power output of the limbs and how that changes between different terrains,” said Dr Basu.
