Prof Bahta
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.

The conservation strategy of the black rhino in Africa needs to change in order to protect the species from extinction, a group of international researchers has found. The study that was published in the Nature Scientific Reports reveals that the species has lost an astonishing 69% of its genetic variation. 

South African researchers took part 
The researchers, which included local researchers from the National Zoological Gardens of South Africa (NZG), have highlighted the fact that this means the black rhino is on the brink of extinction. "We have found that there is a decline in genetic diversity, with 44 of 64 genetic lineages no longer existing," said Prof Antoinette Kotze, the Manager of Research and Scientific Services at the Zoo in Pretoria. She is also affiliate Professor in the Department of Genetics at the University of the Free State and has been involved in rhino research in South Africa since the early 2000s.  

DNA from museums and the wild 
The study compared DNA from specimens in museums around the world, which originated in the different regions of Africa, to the DNA of live wild animals. The DNA was extracted from the skin of museum specimen and from tissue and faecal samples from animals in the wild. The research used the mitochondrial genome.

"The rhino poaching ‘pandemic’
needs to be defeated, because
it puts further strain on the genetic
diversity of the black rhino.”


Ability to adapt 
Dr Desire Dalton, one of the collaborators in the paper and a senior researcher at the NZG, said the loss of genetic diversity may compromise the rhinos’ ability to adapt to climate change. The study further underlined that two distinct populations now exists on either side of the Zambezi River. Dr Dalton said these definite populations need to be managed separately in order to conserve their genetic diversity. The study found that although the data suggests that the future is bleak for the black rhinoceros, the researchers did identify populations of priority for conservation, which might offer a better chance of preventing the species from total extinction. However, it stressed that the rhino poaching ‘pandemic’ needs to be defeated, because it puts further strain on the genetic diversity of the black rhino. 

Extinct in many African countries 
The research report further said that black rhino had been hunted and poached to extinction in many parts of Africa, such as Nigeria, Chad, Cameroon, Sudan, and Ethiopia. These rhino are now only found in five African countries. They are Tanzania, Zimbabwe, Kenya, Namibia, and South Africa, where the majority of the animals can be found.
