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’.”

The first genetically modified (GM) crops in South Africa were planted in 1998. Eighteen years later, the country is one of the largest producers of GM food in the world. Those in support of genetically modified crops say this process is the only way to feed a rapidly growing world population. But those who criticise GM food describe it as a threat to the environment and safety of the population. Who is right? According to Prof Chris Viljoen of the Department of Haematology and Cell Biology at the University of the Free State, neither position is well-founded.

GM crops play a vital role in food security

While GM crops have an important role to play in increasing food production, the technology is only part of the solution to providing sufficient food for a growing world population. The major genetically modified crops produced in the world include soybean, cotton, maize and canola. However, the authenticity of food labelling and the long-term safety of GM food are issues that consumers are concerned about.

Safety and labelling of GM food important in South Africa
In his inaugural lecture on the subject “Are you really going to eat that?” Prof Viljoen addressed the importance of the safety and labelling of GM food in the country. “In order for food to be sustainable, production needs to be economically and environmentally sustainable. On the other hand, food integrity, including food quality, authenticity and safety need to be ensured,” Prof Viljoen said. 

Labelling of food products for genetic modification was mandatory in South Africa, he went on to say. “It allows consumers the right of choice whether to eat genetically modified foods or not.” The Consumer Protection Act of 2008 requires food ingredients containing more than 5% of GM content to be labelled. 

GMO Testing Facility world leader in food diagnostic testing
In 1999, Prof Viljoen spearheaded research in developing a GM diagnostic testing platform, and in 2003, a commercial diagnostic platform for GM status certification, called the GMO Testing Facility, was founded. The facility is a licensed Eurofins GeneScan laboratory   a world leader in food diagnostic testing   and provides diagnostic detection and quantification of genetically modified organisms (GMOs) in grain and processed foods for the local and international market.

Molecular diagnostic technology the future of food integrity, authenticity and safety
With GM labelling now well-established in South Africa, the next challenge is to establish the use of molecular diagnostic technology to ensure that food integrity, including food authenticity and safety is maintained, said Prof Viljoen.

“To the question ‘Are you really going to eat that?’ the answer is ‘yes’, but let’s continue doing research to make sure that what we eat is safe and authentic.”
