The Department of Science and Technology has extended two of the National Research Foundation’s SARChI research chairs at the University of the Free State (UFS). 

The Research Chair in Diseases and Quality of Field Crops, together with the Research Chair in Vector-borne and Zoonotic Pathogens, have both been extended for another five years. 

Prof Maryke Labuschagne, currently Professor of Plant Breeding in the Department of Plant Sciences, is leading the chair on Diseases and Quality of Field Crops.

The Chair on Vector-borne and Zoonotic Pathogens is headed by Prof Felicity Burt from the Division of Virology in the Faculty of Health Sciences.

Prof Corli Witthuhn, Vice-Rector: Research, says it was the hard work and commitment of Profs Labuschagne and Burt that resulted in the extension of the SARChI research chairs. “They have excelled in terms of student supervision and publications in high-impact international journals.  They also serve as mentors for young academics, postdoctoral fellows, and colleagues through their passion for their different fields of interest.”

Prof Witthuhn believes that this extension of the two SARChI chairs speaks of the progress that the UFS has made in terms of developing itself as a research-led university. “We are proud of the two senior academics for their supervision, mentorship, and leadership and their contribution to building our reputation,” she says. 

Diseases and Quality of Field Crops

The focus of the research chair in Diseases and Quality of Field Crops is on advancing food security and nutrition in Africa and contributing to poverty reduction and achieving sustainability goals. 

Prof Labuschagne says despite recent advances, the headlines regarding hunger and food security remain alarming: one in nine people on earth will go to bed hungry every night. Globally, 800 million people do not have enough to eat to be healthy, and a third of all deaths among children under five in developing countries are linked to undernourishment. 

She believes the uniqueness and strength of the research chair lies in a two-pronged approach, namely the breeding of cereal crops for resistance to fungal diseases, and improving the quality of crops for processing and consumption, thus making an impact on food security in South Africa and the rest of Africa through this collaborative effort. 

She is confident that the extension of the research chair will allow them to continue and to expand their research, “which has built up a lot of momentum”.

Besides the 12 PhD and 8 MSc degrees they delivered in the first five years, they also contributed significant research outputs and cultivar releases. She adds that they would like to expand on the significant international collaboration they have established. 

Vector-borne and Zoonotic Pathogens

According to Prof Burt, the SARChI chair in Vector-borne and Zoonotic Pathogens builds on existing research strengths at the UFS and aims to contribute towards identifying and investigating medically significant arboviruses and zoonotic viruses in the country.
 
“To date, the research chair has facilitated progress towards establishing serosurveillance studies for various vector-borne viruses, specifically Crimean-Congo haemorrhagic fever virus, a tick-borne and zoonotic virus that causes severe disease with fatalities.”

The team of researchers operating within this research chair is currently also performing studies to determine the seroprevalence of severe acute respiratory coronavirus 2 (SARS-CoV-2) in the Free State.

Prof Burt has always taken the importance of community engagement into account, and with the current pandemic, she believes that it is now more important than ever to increase public awareness of zoonotic diseases.

She emphasises that the majority of new and emerging viruses are zoonotic in origin and that the current SARS-CoV-2 pandemic highlights the impact of an emerging zoonotic pathogen on society. Therefore, she feels that it is important to build capacity in this field and to focus research efforts on identifying and understanding where these pathogens cycle in nature, the potential for spill-over to humans, and what the drivers are for the emergence of these pathogens.

Prof Burt trusts that the renewal of the research chair will allow them to take advantage of the new biosafety laboratory that the UFS has invested in. “This will permit us to research pathogens that were previously excluded from our programme due to biosafety considerations.  The chair will furthermore contribute towards enhancing, strengthening, and developing research and knowledge in the field of epidemiology and pathogenesis of vector-borne and zoonotic viruses,” she says.

Shack study holds research and social upliftment opportunities

When Prof Basie Verster, retired head of the Department of Quantity Surveying at the University of the Free State (UFS), initiated an alternative form of housing for Johannes - one of his employees - a decision was made to base research on this initiative. This research project in Grasslands, Heidedal focused on the cost and energy efficiency of green and/or sustainable shacks.

Esti Jacobs from the Department of Quantity Surveying, together with an honours student in Quantity Surveying, a master’s student in Architecture, and young professionals at Verster Berry, helped with the project.

The physical goals of the project were to create a structure that is environmentally friendly, and maintains a comfortable interior climate in winter and summer, as well as being cost-effective to erect. The structure also had to be socially acceptable to the family and the community.

“The intention was to make a positive contribution to the community and to initiate social upliftment through this project. Structures such as the ‘green shack’ may serve as an intermediate step to future housing possibilities, since these structures are relatively primitive, but have economic value and could be marketable,” she said.

Esti explains the structure of the building, which consists of gum poles and South African pine bearers, with a timber roof and internal cement block flooring. The building is clad with corrugated iron and has a corrugated iron roof finish. Additional green elements added to the structure were internal Nutec cladding, glasswool insulation in walls, internal gypsum ceiling boards with ‘Think Pink’ insulation, internal dividing wall and door, polystyrene in the floors, and tint on the windows. A small solar panel for limited electricity use (one or two lights and electricity to charge a cellphone) and a Jojo water tank for household consumption by the inhabitants were also installed.

Esti said: “Phase one of the research has been completed. This phase consisted of an investigation into the cost of an alternative form of housing structure (comparing traditional shacks with the planned structure) as well as the construction process of the physical housing structure.

“Phase two of the research, commencing in February 2015, will last for two to three years. This phase will include the installation of temperature and relative humidity logging devices inside the existing traditional shack and the new green shack. The logs will be regularly monitored by the UFS Department of Quantity Surveying and Construction Management.

These data will enable the researchers to measure the differences in comfort levels inside the two different structures. The data, together with other information such as building materials and methods, are then processed by software programs. Through the simulation of different environments, building materials, and alternate forms of energy, software models can be used to come up with conclusions regarding more energy-friendly building materials and methods. This knowledge can be used to improve comfort levels within smaller, low-cost housing units.

The UFS will be working with Prof Jeff Ramsdell of the Appalachian State University in the USA and his team on the second phase of the project.

“This research project is ongoing and will be completed only in a few years’ time,” said Esti.

The results of the research will be published in accredited journals or at international conferences.
