Prof Yonas Bahta
Prof Yonas Bahta, Professor in the Department of Agricultural Economics at the University of the Free State, delivered his inaugural lecture on the future of agricultural trade and food security, titled Can We Own the Future? The Ever-Changing Dynamics of Agricultural Trade and Food Security Amid Intensifying Agricultural Drought.

With the world hurtling towards a population of 9,7 billion by 2050 – and Africa set to make up more than a quarter of that – the question of whether we can ‘own the future’ has never been more urgent. In his inaugural lecture at the University of the Free State (UFS), Prof Yonas Bahta from the Department of Agricultural Economics warned that climate change, trade tensions, and deepening food insecurity are converging to create unprecedented risks for farmers, economies, and communities.

“We find ourselves at a pivotal moment in human history, characterised by the intersection of climate change, particularly agricultural drought, resource scarcity, geopolitical instability, and the current trade reciprocal tariff, all of which pose significant threats to the foundational structures of global food systems,” he said.

 

From vulnerability to agency

Prof Bahta highlighted the stark reality that the world population is projected to reach 9,7 billion by 2050, with Africa constituting 2,5 billion. “Despite this growth, the agricultural sector predominantly operates at a subsistence level, with diminishing resources available to farming communities, especially smallholder farmers who rely on agriculture as their primary source of employment and sustenance.”

In South Africa, climate change – particularly agricultural drought – is affecting both commercial and smallholder farmers, with cascading effects on food security, employment, and livelihoods. Coupled with disease outbreaks, these factors lead to reduced crop yields, supply shocks, and trade imbalances that ripple through the economy.

Food insecurity remains a critical concern, with approximately 15 million South African households experiencing moderate to severe food insecurity – a figure even higher (25,5%) among households engaged in agricultural activities. Prof Bahta emphasised that these challenges are compounded by “institutional barriers such as the current trade reciprocal tariff by the USA, limited access to credit, crop and livestock insurance, inadequate road infrastructure, and electricity shortages”.

Despite these challenges, Prof Bahta sees clear opportunities. He pointed to Africa, including South Africa’s extensive arable land; research and innovation have highlighted the benefits of integrating traditional techniques with modern approaches such as climate-smart agriculture and its membership of BRICS and other trading partners as levers for resilience and growth. “Securing the future is not about mere assertion but about the stewardship of markets, data, and people,” he said. By aligning trade policy, drought preparedness, and social protection within robust institutions, “the country can transition from vulnerability to agency, from passively observing the future to actively shaping it. In doing so, we may indeed assert with integrity that ‘We own the future’.”

Art and science help us understand the world and our place in it

Although BioArt dates back as far as the 15th and 16th centuries with the work of Leonardo da Vinci, it is not every day that art and science combine. This rare phenomenon made its appearance when two totally different groups of students – studying arts and microbiology respectively – joined hands in an initiative to create BioArt.

This first-time undergraduate teaching collaboration between the Departments of Fine Arts and Microbial, Biochemical and Food Biotechnology at the University of the Free State (UFS), which is characterised by the use of living materials, such as enzymes, microbes and DNA, as well as scientific tools and methods, is exploring a number of questions. 

Different outcomes for arts and microbiology students

According to Prof Carlien Pohl-Albertyn from the Department of Microbiology, Biochemical and Food Biotechnology, one of the central questions explored in BioArt is the nature of ‘life’. “At which stage can matter be classified as being alive or living?” she asked. 

“We realised that the outcomes for the two groups of students would not be the same. For the microbiology students, the focus would be on the understanding and effective communication of a microbiological concept. For the art students the focus would be on the execution of the assignment using visual elements and applied theory of art,” said Prof Pohl-Albertyn.

Dr Janine Allen-Spies from the Department of Fine Arts added: “Art students will also be exploring strangely or previously unforeseen gaps between art and science that can be filled with imaginative interpretations which may forward creative insights in both BioArt as a developing art form and microbiology as investigative science.”

Students’ understanding of microbial evolution reflected in art
The art students had to visit the microbiology labs for their assignment as this is mostly a foreign environment for these students. “The paint medium they had to use was gouache. This medium with its bright colours works well to depict microscopic organisms in art,” Dr Allen-Spies said. 

On display at the Department of Microbial, Biochemical and Food Biotechnology on the Bloemfontein Campus, at a recent event to introduce this new initiative to a wider audience, was a range of visually and scientifically compelling paintings and artefacts (such as paintings, poems, songs, apps) which explore a theme within microbiology from a BioArt perspective that uses creativity to communicate concepts dealt with in the module Microbial Evolution and Diversity.

Any parties who are interested in buying the art can contact Dr Allen-Spies at allenj@ufs.ac.za.

Paintings and artefacts reflects students understanding of BioArt. At the recent opening of the BioArt exhibition at the UFS Department of Microbial, Biochemical and Food Biotechnology, was the work of Madeleen Jansen van Rensburg on display.

Pheny Mokawane, a Microbiology, Biochemical and Food Biotechnology student, wrote a poem for his BioArt project in the Microbial Evolution and Diversity assignment.
