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’.”

Fracking in the Karoo has advantages and disadvantages

Fracking for shale gas in the Karoo was laid bare during a public lecture by Dr Danie Vermeulen, Director of the Institute for Groundwater Studies (IGS). He shared facts, figures and research with his audience. No “yes” or “no” vote was cast. The audience was left to decide for itself.

The exploitation of shale gas in the pristine Karoo has probably been one of the most debated issues in South Africa since 2011.
 
Dr Vermeulen’s lecture, “The shale gas story in the Karoo: both sides of the coin”, was the first in a series presented by the Faculty of Natural and Agricultural Science under the theme “Sustainability”. Dr Vermeulen is a trained geo-hydrologist and geologist. He has been involved in fracking in South Africa since the debate started. He went on a study tour to the USA in 2011 to learn more about fracking and he visited the USA to further his investigation in May 2012.
 
Some of the information he shared, includes:

- It is estimated that South Africa has the fifth-largest shale-gas reserves in the world, following on China, the USA, Argentina and Mexico.
- Flow-back water is stored in sealed tanks and not in flow-back dams.
- Fracturing will not contaminate the water in an area, as the drilling of the wells will go far deeper than the groundwater aquifers. Every well has four steel casings – one within the other – with the gaps between them sealed with cement.
- More than a million hydraulic fracturing simulations took place in the USA without compromising fresh groundwater. The surface activities can cause problems because that is where man-made and managerial operations could cause pollution.
- Water use for shale-gas exploration is lower than for other kinds of energy, but the fact that the Karoo is an arid region makes the use of groundwater a sensitive issue. Dr Vermeulen highlighted this aspect as his major concern regarding shale-gas exploration.
- The cost to develop is a quarter of the cost for an oil well in the Gulf of Mexico.
- Dolerite intrusions in the Karoo are an unresearched concern. Dolerite is unique to the South African situation. Dolerite intrusion temperatures exceed 900 °C.

He also addressed the shale-gas footprint, well decommissioning and site reclamation, radio activity in the shale and the low possibility of seismic events.
 
Dr Vermeulen said South Africa is a net importer of energy. About 90% of its power supply is coal-based. For continued economic growth, South Africa needs a stable energy supply. It is also forecast that energy demand in South Africa is growing faster than the average global demand.
 
Unknowns to be addressed in research and exploration are the gas reserves and gas needs of South Africa. Do we have enough water? What will be the visual and social impact? Who must do the exploration?
 
“Only exploration will give us these answers,” Dr Vermeulen said.
