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’.”

Giraffe research broadcast on National Geographic channel
2016-03-09

Description: Giraffe research  Tags: Giraffe research

A documentary focusing on the latest and most interesting research about giraffes was recently broadcasted on National Geographic. Dr Francois Deacon from the UFS Department of Animal, Wildlife and Grassland Sciences and the team of researchers working with him, were first in the world to equip giraffes with GPS collars, and to conduct research on them.

Research by Dr Francois Deacon, from the UFS Department of Animal, Wildlife and Grassland Sciences, involving the equipping of giraffes with GPS collars, was broadcast this week as part of a documentary (4 March 2016 and subsequent weeks) on National Geographic (Channel 182). The documentary is the first of two on his team's research.

Dr Deacon and the team of researchers working with him were the first in the world to equip giraffes with GPS collars, and to conduct research on this initiative. The group of researchers can now follow the animals night and day by means of the GPS collars, while monitoring their movements from a distance on a computer screen and seeing the world from a giraffe's perspective.

“The documentary focuses on the latest and interesting information about our research in different countries,” Dr Deacon said. Besides their local research on giraffes, he and his team also assist in other projects and research in Namibia, Botswana, Zambia, Kenya, the Democratic Republic of the Congo, and Uganda.

“There is much to learn from the documentary,” Dr Deacon said. Interesting facts from their research include herd interactions by individuals towards each other, bulls versus bulls, and cows versus calves. In the documentary, the viewer can also learn how giraffes use thermoregulation, their tongues, and roaming areas and distances; peculiar behaviour such as feeding on bones and soil; bulls fighting; how and when giraffes drink water; and the conservation and management of giraffes.
 
Focus is also placed on the manner in which the latest research plays a role in the better understanding of the animals.
 
According to Dr Deacon, this is the first documentary to focus on giraffe research on such a large scale. Marco Polo Films from Terra Mater are contracted by National Geographic to produce nature films – this was the hundredth nature film produced by them.
 
“There has never before been such a production about giraffes. It also attracted huge interest and reaction overseas, which will provide great exposure for our research and for the UFS.
 
“We believe that the media involvement will provide much more exposure to giraffes, which is a good thing, since they are facing extinction in Africa. The exposure can, in itself, lead to new research and has already started attracting international students to the UFS,” Dr Deacon said.
 
The second documentary will follow later this year. Iniosante, a film team from Texas, USA, is producing this film, which focuses on the extinction of giraffes. It is the same team responsible for the production Last of the Longnecks.
