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’.”

Thirty-year-old Prof Abdon Atangana has received the prestigious Sentinels of Science Award 2016. This award honours the highest achievers in peer review across the world’s journals. The elite contributors to scholarly peer review and editorial pursuits internationally are also honoured with this award. Recipients have demonstrated an outstanding, expert commitment to protecting the integrity and accuracy of published research in their field.

Prof Atangana, who ranks number one in the mathematics discipline with a merit of 324, is a professor at the Institute for Groundwater Studies at the University of the Free State (UFS).

He is editor of 17 international journals, editor-in-chief of two international journals and also reviewer of more than 200 international accredited journals. He has been lead and guest editor of some special issues. He is also editor of 19 journals of applied mathematics and mathematics and has presented and participated in more than 20 international conferences.

Prof Atangana’s research interests are methods and applications of partial and ordinary differential equations, fractional differential equations, perturbations methods, asymptotic methods, iterative methods, and groundwater modelling.

“Editors in more than 100 journals
trust my opinion to assess
whether a submitted paper
can be published or not.”

Peer review requires a respected expert in a given field

According to the professor, reviewers play a central role in scholarly publishing. “In the academic field, peer review is the process of subjecting an author’s scholarly work, research, or ideas to the scrutiny of others who are experts in the same field, before a paper describing this work is published in a journal or as a book. The peer review process helps the publisher to decide whether the work should be accepted, considered acceptable with revisions, or rejected.

“Peer review requires a respected expert in a given field, who is qualified and able to perform the review in a given timeframe. Due to the impact of my research papers in the field of mathematics and applied mathematics, and also my international recognition in the field of applied mathematics, many editors in more than 100 journals of applied mathematics trust my opinion to assess whether a submitted paper in a given journal of mathematics and applied mathematics can be published or not. Only this year I was able to review more than 100 papers from different journals of applied mathematics, applied physics, mathematics, engineering and hydrology,” he said.

A successful peer reviewer displays passion for the development of science

Key to his success as peer reviewer is his passion for the development of science, his ability to write fair reports about a given manuscript, as well as his knowledge on what has been done and what are the challenges in a given field to be able to give a report that will help the advancement of science.

Currently he is developing new mathematics tools that will be used to accurately model statistical problems as well as physical problems with many layers.

“To be the number one peer reviewer in the world in mathematics is a product of love, patience and determination to enhance science,” Prof Atangana said.

His advice to young researchers is to put their trust in God and to work hard. “Not necessarily for money but for love because the future of Africa is in the hands of young Africans,” he said.
