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’.”

Summit programme

The third world summit in the International Year of Crystallography (in Africa) will be hosted by the UFS Department of Chemistry here on the Bloemfontein Campus. Prof André Roodt, Head of the Department of Chemistry, was elected as the President of the European Crystallographic Association in 2012. Earlier this year he unveiled the Max von Laue 'Plaque' in Posnan, Poland.

The Pan-African Meeting of the International Year of Crystallography consists of a congress and summit. The details are as follows:

Congress
12–15 October 2014
CR Swart Senate Hall, UFS Bloemfontein Campus

Summit

15–17 October 2014
CR Swart Senate Hall, UFS Bloemfontein Campus
Summit opening: Wednesday 15 October 2014 at 14:00 in the CR Swart Senate Hall

This event will be opened and attended by:
•    the UFS Rector and Vice-Rector – Profs Jonathan Jansen and Corli Witthuhn;
•    the acting Director-General of the Department of Science and Technology – Dr Thomas Auf der Heyde;
•    the acting CEO of the National Research Foundation – Dr Gansen Pillay;
•    the UNESCO Vice-Director for Science Extension – Dr Jean-Paul Ngome-Abiaga (Paris, France);
•    the representative of the Executive Committee for the International Union of Crystallography (IUCr) – Prof Santiago Garcia-Granda (Oviedo: Spain);
•    the marketing director of the IUCr – Prof Michele Zema (Pavia, Italy);
•    the President of the European Crystallographic Association (ECA) – Prof André Roodt, who will officially open the summit on Wednesday 15 October 2014 from 14:00–15:30.

Presenters from across Africa and Europe will deliver papers at this event which will be attended by more than 100 delegates from twenty-plus countries, including Spain, France, Italy, Croatia, Germany, Russia and India.

Numerous crystallographic research areas will be covered. This includes:
•    powder diffraction,
•    small molecule crystallography,
•    biological crystallography,
•    industrial crystallography,
•    surface crystallography,
as well as techniques such as
•    electron microscopy and
•    synchrotron work.

“At this event we hope to establish an African Crystallographic Association,” said Prof Roodt.

The United Nations declared 2014 as the International Year of Crystallography. It was recently officially opened at the UNESCO headquarters in Paris, France, by the Secretary General of the UN, Ban Ki-moon.

The International Year of Crystallography celebrates the centennial of the work of Max von Laue and the father and son, William Henry and William Laurence Bragg. More generally, it celebrates what crystallography can do for humanity – which proves to be a significant amount.
