For the past three years, Prof Yonas Bahta has studied the resilience of smallholder livestock farmers in agricultural drought, and the competitiveness of agri-food commodities.

The agricultural sector is marked by farmers’ daily struggles, including price hikes, climate change effects, and pest and disease outbreaks.

Prof Yonas T Bahta, Associate Professor and astute National Research Foundation (NRF) C2-rated researcher in the Department of Agricultural Economics at the University of the Free State (UFS), found that smallholder farmers who received drought relief support saw an improvement in their welfare. The study also found that economic capital, social capital, human capital, and natural capital substantially affected the welfare of smallholder farmers.

Agricultural drought

These findings came from the study, titled: The resilience of households to agricultural drought in the Northern Cape province of South Africa. Prof Bahta’s aim with this study was threefold – to assess household resilience to agricultural drought among smallholder livestock farmers, to evaluate the welfare of smallholder farming households affected by agricultural drought, and to identify factors influencing agricultural drought resilience and food insecurity among smallholder livestock farmers.

During his investigation, he found that only 9% of the smallholder livestock farmers were resilient to agricultural drought. According to him, farming households with access to credit, farmers who received assistance from the government (such as training and feed) during drought, and farmers who are part of a cooperative proved to be more resilient to agricultural drought.

When it comes to food security, he discovered that assets, social safety nets, and indicators of adaptive capacity had a positive influence on households' ability to withstand food insecurity. Alternatively, climate change indicators negatively impacted households’ resilience to food insecurity.

For the past three years, he has studied the resilience of smallholder livestock farmers in agricultural drought. He believes that resilience – the ability to bounce back from adversities – is crucial.

According to him, both the smallholder livestock sector (farmers) and the agrifood industry need to develop resilience to effectively cope with and recover from agricultural drought, macroeconomic stability (inflation), competitiveness, productivity, and other related factors.

Competitiveness of agri-food commodities

Prof Bahta also launched investigations into the competitiveness of agri-food commodities in South Africa as well as Namibia.

The studies were titled: Competitiveness of Namibia’s Agrifood Commodities: Implications for Food Security and Competitiveness of South Africa’s Agrifood Commodities.

In these studies, he respectively looked at the competitiveness of South Africa’s and Namibia’s agrifood products, the factors that influence it, and its implication for food security.

In both countries, he discovered a combination of comparative advantage and disadvantage.

“South Africa and Namibia exhibited a trade structure that was less concentrated and not dependant on international trade in the agri-food industry, having minimal impact on Namibia's food security. The productivity of agriculture and GDP per capita positively influenced the comparative advantage of South Africa, whereas land productivity and GDP per capita influenced the degree of food insecurity in Namibia,” explains Prof Bahta the main research findings.

Research outputs

The study on the resilience of smallholder livestock farmers was supported by funding from the National Research Foundation. To explore the competitiveness of agri-food commodities, Prof Bahta collaborated with the Namibia University of Science and Technology (NUST), benefiting from their strong existing academic relationship. The UFS Office for International Affairs played a key role in facilitating this study, with research partnerships existing between the universities of both countries.

According to Prof Bahta, the findings of these two studies have resulted in the publication of more than 13 articles in journals ranking in the highest (Q1) and second highest categories (Q2) in the specific field. A paper will also be presented at the upcoming International Food and Agribusiness Management Association (IFAMA) international conference in New Zealand from 17 to 20 June 2023.

Furthermore, five popular articles on the main findings of the studies (written in non-technical language) were also published on these topics, focusing on the farmers and policy makers (as a policy brief and popular) as the target audience. These articles looked at, among others, the impact of policy intervention on food insecurity in times of shock; coping strategies of smallholder livestock farmers during food insecurity shocks; measuring the resilience of female smallholders in South Africa; and farming for success.

This study also resulted in the graduation of three master's students (two with distinction) and three honours students.

Looking ahead, Prof Bahta emphasises the necessity for conducting similar studies targeting both commercial and smallholder farmers, focusing on crops and livestock in various provinces across South Africa. He also feels that connections need to be established with universities besides NUST.

State-of-the-art physics equipment and investment in students result in academic success

Nanoscience, which is revealing new properties of very small arrangements of atoms, called nanoparticles, is opening a new world of possibilities. The Department of Physics at the University of the Free State is undertaking fundamental research with potential commercial applications. Its equipment and expertise is giving solid state physics research the edge in South Africa.

The UFS team of researchers and students are passionate about studying planets and atoms, all under one roof. Recently, the department, in collaboration with the South African Agency for Science and Technology Advancement (SAASTA), hosted a nanotechnology facility tour to give the public, learners and the media the opportunity to familiarise themselves with the science of nanotechnology, its origins, potential applications and risks.

Successes of the department
According to Prof Hendrik Swart, Senior Professor in the Department of Physics, the increase in resources since 2008 is playing a big role in the success rate of its research outputs. The Sarchi Chair awarded to Prof Swart in 2012 (bringing with it funding for equipment and bursaries) also contributed to the successes in the department.

The UFS Directorate Research Development also availed funding that was used for bursaries. These bursaries made it possible for the department to appoint 10 post-doctoral fellows, not one of them originally from South Africa.

The investment in people and equipment resulted in researchers and students publishing some 80 articles in 2016. Their work was also cited more than 900 times by other researchers in that year.

Another highlight in terms of the department’s growth in the past 10 years is the new wing of the Physics Building. Physics at the UFS is the only place in sub-Saharan Africa where state-of-the art equipment is found under one roof.

Application of research
The department is a unique research facility with equipment that includes the X-ray Photoelectron Spectrometer (for the study of atoms), the Scanning Auger Microscope, as well as the Ion Time-of-Flight Secondary Ion Mass Spectrometer (revealing the chemical bonds in a sample, and drawing maps of the positions of atoms).

One of the areas on which the department is focusing its research, is phosphors. Researchers are exploring light emitting diodes (LEDs) which use less energy, are brighter and provide a wider viewing field. They are also looking into LED displays (LCDs) which are used in flat screens – the phosphors create the different colours and backlighting.

The research on solar cells reveals that phosphors can increase their efficiency by increasing the range of light frequencies which can be converted into electricity. Glow-in-the-dark coatings absorb light in the day and emit it later so cells can charge at night. As glow-in-the-dark phosphors become cheaper and more effective, they can be used as a lighting substitute on the walls of houses, street numbers and stop signs.
