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’.”

Little ‘Devil’s Worm’ on Top 10 New Species list

A minuscule little worm found and researched with the assistance of researchers at the university has made it onto the list of Top 10 New Species of the world. The list was published by the International Institute for Species Exploration (IISE) at Arizona State University and a committee of scientists from around the world. It lists the top ten new species described in 2011.

An article on the new worm species appeared in the authoritative journal Nature in June 2011.
 
Prof. Esta van Heerden, leader of the university’s research team, says, “In our wildest dreams, we could not have imagined that we would get so much reaction from the worm’s discovery. We had to do so many checks and balances to convince Nature that the worm could survive in the old and warm water. We were very excited when the article was accepted but the media reaction was unbelievable.”
 
The tiny nematode, Halicephalobus mephisto (Devil’s Worm) of about 0,5 mm in length, is the deepest-living terrestrial multi-cellular organism on earth. It was discovered in the Beatrix gold mine near Welkom at a depth of 1,3 km.
 
The IISE says in a statement the species is remarkable for surviving immense underground pressure as well as high temperatures. The borehole water where this species lives has not been in contact with the earth’s atmosphere for the last 4 000 to 6 000 years.  
 
This top-10 list includes a sneezing monkey; a beautiful, but venomous jellyfish; a fungus named after a popular TV cartoon character; a night-blooming orchid; an ancient walking cactus creature; and a tiny wasp. A vibrant poppy, a giant millipede and a blue tarantula also made it onto the list.
 
The international selection committee made its choice from more than 200 nominations. They looked for species that captured the attention because they were unusual or because they had bizarre traits. Some of the new species have interesting names.
 
Prof. Van Heerden says, “We are very thankful for the exposure that the university gets as a result of the inclusion on the list and we enjoy the international cooperation immensely.”
