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’.”

#Women'sMonth: Long hours in wind and cold weather help to reconstruct Marion Island’s glacial history

Liezel Rudolph, a lecturer for second-year students in Process Geomorphology, aims to reconstruct the glacial history of Marion Island through cosmogenic nuclide dating techniques. She is interested in periglacial geomorphology, a study of how the earth’s surface could be formed by ice actions (freezing and thawing of ice).

Liezel is a lecturer in the Department of Geography at the university and is researching landscape development specifically in cold environments such as Antarctica, the Sub-Antarctic islands, and high mountain areas. “My involvement with periglacial geomorphology is largely due to academic giants who have carved a pathway for South Africans,” says Liezel.

Liezel visited Marion Island for the first time during her honours year in 2011, when she investigated the impact of seals on soil conditions and vegetation. Three years later, she visited Antarctica to study rock glaciers.

The challenge of the job
A workday in Antarctica is challenging. “Our time in the field is very limited, so you have to work every possible hour when the weather is not life-threatening: from collecting soil samples, to measuring soil temperature and downloading data, we measure polygons and test the hardness of rocks. The only way to get the amount of work done, is to work long hours in wind and rain with a positive and competent team! We take turns with chores: the person carrying the notebook is usually the coldest, while the rest of us are stretching acrobatically over rocks to get every nook and cranny measured and documented.”

A typical workday
Liezel describes a typical workday: “Your day starts with a stiff breakfast (bacon and eggs and a bowl of oats) and great coffee! After that comes the twenty-minute dressing session: first a tight-fitting under-layer, a middle layer – sweater and T-shirt, and then the outer windbreaker (or a quilt jacket on an extra cold day). Then you start applying sunscreen to every bit of open face area. Beanie on, sunglasses, two pairs of socks, two pairs of gloves. The few kilograms of equipment, one vacuum flask containing an energy drink, one vacuum flask containing drinking water (it would freeze in a regular bottle), and a chocolate bar and piece of biltong for lunch. After this, we drive (on snowmobiles) or fly (in helicopter) to our study area for about eight hours of digging, measuring, downloading, testing and chopping. Back at the base and after a long and tiresome undressing session, we move to the lab with all our data to make sure that it is downloaded safely and captured onto a database. Afterwards, depending on the day of the week, we enjoy a good meal. If you are lucky, such a typical day will coincide with your shower day. We can only shower every second day due to the energy-intensive water production (we have to melt snow) and the sewage system (all the water has to be purified before it could be returned to the environment). Then you grab your eye shield (since the sun is not sinking during summer) and take a nap before the sun continues to shine into the next day.”

Theoretical knowledge broadened 
“Going into the field (whether island or mountains) provides me with an opportunity to test geomorphic theories. Without experience in the field, my knowledge will only be limited to book knowledge. With practical experience, I hope to broaden my knowledge so that I could train my students from experience rather than from a textbook,” says Liezel.
