Agriculture Supply Chain - Ukraine
On Thursday 7 September 2023, the University of the Free State (UFS) presented its fifth webinar titled, The need for a global and regional plan/approach to respond to the consequences of the Russia-Ukraine war, as part of the 2023 Thought-Leader Webinar Series.

Africa must avoid being instrumentalised by external conflict

In the wake of Russia's invasion of Ukraine, the world has been grappling with the far-reaching consequences of this conflict. The effects can be felt globally – affecting economies, supply chains, and vital issues on the international agenda. These are some of the points discussed in the recent Thought-Leader webinar held by the University of the Free State (UFS). The webinar titled, The need for a global and regional plan/approach to respond to the consequences of the Russia-Ukraine war, brought together experts such as Wandile Sihlobo, Chief Economist at the Agricultural Business Chamber of South Africa; Elizabeth Sidiropoulos, Chief Executive of the South African Institute of International Affairs; Dr Jakkie Cilliers, Chairperson of the Institute for Security Studies; and Prof Philippe Burger, Dean of the Faculty of Economic and Management Sciences, UFS.

The webinar was facilitated by Prof Francis Petersen, Vice-Chancellor and Principal of the UFS.

Exploring Africa’s long-term future

Dr Cilliers delved into the long-term future of Africa; drawing comprehensive insights, his analysis highlighted the global shifts and their impact on the continent. He projected that China would surpass the United States as the world's most powerful country by mid-century, emphasising the need for Africa to navigate relations with both China, the EU, and the US for its development.

Four global scenarios were presented by Dr Cilliers: a sustainable world, a divided world, a world at war, and a growth world. The most probable scenario appeared to be a divided world, characterised by fragmented international relations and a growing divide between the wealthy West and the rest of the world. He stressed the importance of Africa pursuing geopolitical stability, avoiding being instrumentalised by external conflicts, and working towards a fair, rules-based global system.

He also touched on Russia's influence in Africa, noting its role in proxy wars and coups d'etat aimed at disrupting Western influence. “While Russia's direct presence in Africa was relatively small, its capacity to undermine the West and impact Africa's development prospects was significant,” said Dr Cilliers. He cautioned against overestimating Russia's influence and emphasised the need for a more nuanced understanding of the complex factors affecting Africa's future.

Global paradigm shifts

Sidiropoulos placed the ongoing war and global developments in a broader context, emphasising the need for a significant shift in how we perceive the world and its norms, calling for changes in economics, politics, and even ideology. Regarding the Ukraine conflict, she noted its role as a proxy and European war with far-reaching global consequences, highlighting the importance of understanding its historical context.

She discussed the evolving dynamics of the Ukraine conflict, where neither side has achieved its desired outcomes. She emphasised the potential for war fatigue and the need to consider alternative pathways, such as dialogue and negotiation, to avoid a frozen conflict or an outright victory by one party. She also underscored Russia's continued relevance as a great power with nuclear capabilities, prompting questions about the future of European security arrangements.

Shifting her focus to South Africa and Africa as a whole, Sidiropoulos stressed the importance of understanding the foreign policy of major global players such as Russia, China, and India. “As these countries rise in influence, it becomes essential to navigate their policies, both in terms of national interest and values,” she added.

Nonalignment and South Africa's foreign policy challenges

Sidiropoulos discussed the challenges presented by South Africa’s non-aligned stance. “There is a need for a coherent government-wide strategy, clear messaging, and the ability to make decisions based on issues and national interests rather than being automatically aligned with one camp or another.” The importance of preserving policy space and balancing economic interests with fundamental principles in international relations was emphasised.

She called on African countries to adopt a more proactive stance in shaping their path and ensuring that national interest serves the citizens and society, not just the elite. She stressed the importance of economic independence, not isolation, by leveraging opportunities such as the African Continental Free Trade Area (AfCFTA), diversifying production, and strengthening governance for accountability.

Strengthening regional value chains

Sihlobo emphasised the vulnerability of the continent's food supplies and stressed Africa's dependence on food imports, highlighting that the continent imports approximately $80 billion worth of agricultural food, fibre, and beverage products. “Vulnerabilities in the food supply chain existed before the war due to factors such as drought, conflicts in East Africa, and COVID-19 supply chain disruptions. These vulnerabilities disproportionately affected Africa's poor households,” said Sihlobo.

South Africa, in contrast to much of Africa, exports nearly half of its agricultural production, amounting to around $13 billion in value. Despite exporting record volumes in 2022, South Africa has not escaped the price transmission effects of global disruptions, resulting in food inflation concerns. However, South Africa's situation was relatively better due to its export-oriented agriculture.

Sihlobo emphasised the need for Africa to strengthen regional value chains to insulate itself from external shocks. “Regional cooperation, productivity improvements, infrastructure development, and investments are essential for Africa's agricultural sector to thrive,” he added.

To enhance agricultural productivity in Africa, Sihlobo highlighted the importance of political stability, good governance, and infrastructure development. Productivity gains must replace extensive land expansion, with governments promoting sustainable agricultural practices.

Need for ongoing containment

Prof Burger highlighted the importance of containment as a policy approach to address the ongoing Russia-Ukraine crisis. He emphasised the need to consider the moral, economic, and political dimensions of the crisis, while recognising its historical context.

He noted that the initial invasion of Ukraine led to spikes in global inflation. However, subsequent developments, including a military containment, contributed to a decrease in inflation rates. He likened the current military stalemate to World War I's trench warfare and the lack of significant military progress for protracted periods of time. He also highlighted that the Black Sea Grain Initiative (BSGI) of 2022 has expired, and Russia has shown reluctance to renew it. This ongoing stalemate and the risks associated with the non-renewal of the BSGI have raised questions about the prospects of the crisis.

Prof Burger discussed the concept of containment, differentiating between long-run changes in input prices and short-term fluctuations. “Successful containment involves interventions that prevent price movements from deviating significantly from long-term levels.” He pointed to successful containment interventions during the COVID-19 pandemic and the Russia-Ukraine crisis. These measures included economic stimuli, vaccine distribution, rerouting of grain exports, and ensuring stable energy supply.

He briefly discussed the role of the expanded BRICS (Brazil, Russia, India, China, South Africa), which now includes Saudi Arabia, the UAE, Egypt, Ethiopia, Iran, and Argentina, in the context of the crisis. While acknowledging divisions within the group, he noted that BRICS allows China and India to pursue their international programmes more independently.

Prof Burger concluded by highlighting the need for containment in the face of a long-term military stalemate or the absence of a clear Ukrainian victory. He argued that containment in the form of a long-term ceasefire as in the Kashmir and Korea conflicts might be the most viable solution. In addition, the stability of the Putin regime and Western support for the Zelensky government would be crucial factors in determining the trajectory of the crisis.

CONTROL OF INFECTIOUS AVIAN DISEASES – LESSONS FOR MAN?

“Many of the lessons learnt in disease control in poultry will have application on human medicine,” said Prof Robert Bragg, lecturer at the University of the Free State’s (UFS) Department of Microbial, Biochemical and Food Biotechnology during his inaugural lecture.

Prof Bragg said the development of vaccines remains the main stay of disease control in humans as well as in avian species.  Disease control can not rely on vaccination alone and other disease-control options must be examined.  

“With the increasing problems of antibiotic resistance, the use of disinfection and bio security are becoming more important,” he said.

“Avian influenza (AI) is an example of a disease which can spread from birds to humans.  Hopefully this virus will not develop human to human transmission,” said Prof Bragg.

According to Prof Bragg, South Africa is not on the migration route of water birds, which are the main transmitters of AI.  “This makes South Africa one of the countries less likely to get the disease,” he said.

If the AI virus does develop human to human transmission, it could make the 1918 flu pandemic pale into insignificance.  During the 1918 flu pandemic, the virus had a mortality rate of only 3%, yet more than 50 million people died.

Although the AI virus has not developed human-to-human transmission, all human cases have been related to direct contact with infected birds. The mortality rate in humans who have contracted this virus is 67%.

“Apart from the obvious fears for the human population, this virus is a very serious poultry pathogen and can cause 100% mortality in poultry populations.  Poultry meat and egg production is the staple protein source in most countries around the world. The virus is currently devastating the poultry industry world-wide,” said Prof Bragg.

Prof Bragg’s research activities on avian diseases started off with the investigation of diseases in poultry.  “The average life cycle of a broiler chicken is 42 days.  After this short time, they are slaughtered.  As a result of the short generation time in poultry, one can observe changes in microbial populations as a result of the use of vaccines, antibiotics and disinfectants,” said Prof Bragg.   

“Much of my research effort has been directed towards the control of infectious coryza in layers, which is caused by the bacterium Avibacterium paragallinarum.  This disease is a type of sinusitis in the layer chickens and can cause a drop in egg product of up to 40%,” said Prof Bragg.

The vaccines used around the world in an attempt to control this disease are all inactivated vaccines. One of the most important points is the selection of the correct strains of the bacterium to use in the vaccine.

Prof Bragg established that in South Africa, there are four different serovars of the bacterium and one of these, the serovar C-3 strain, was believed to be unique to Southern Africa. He also recently discovered this serovar for the first time in Israel, thus indicating that this serovar might have a wider distribution than originally believed.

Vaccines used in this country did not contain this serovar.  Prof Bragg established that the long term use of vaccines not containing the local South African strain resulted in a shift in the population distribution of the pathogen.

Prof Bragg’s research activities also include disease control in parrots and pigeons.   “One of the main research projects in my group is on the disease in parrots caused by the circovirus Beak and Feather Disease virus. This virus causes serious problems in the parrot breeding industry in this country. This virus is also threatening the highly endangered and endemic Cape Parrot,” said Prof Bragg.

Prof Bragg’s research group is currently working on the development of a DNA vaccine which will assist in the control of the disease, not only in the parrot breeding industry, but also to help the highly endangered Cape Parrot in its battle for survival.

“Not all of our research efforts are directed towards infectious coryza or the Beak and Feather Disease virus.  One of my Masters students is currently investigating the cell receptors involved in the binding of Newcastle Disease virus to cancerous cells and normal cells of humans. This work will also eventually lead to a possible treatment of cancer in humans and will assist with the development of a recombinant vaccine for Newcastle disease virus,” said Prof Bragg.

We are also currently investigating an “unknown” virus which causes disease problems in poultry in the Western Cape,” said Prof Bragg.
 
“Although disinfection has been extensively used in the poultry industry, it has only been done at the pre-placement stage. In other words, disinfectants are used before the birds are placed into the house. Once the birds are placed, all use of disinfectants stops,” said Prof Bragg.

“Disinfection and bio security can be seen as the ‘Cinderella’ of disease control in poultry.  This is also true for human medicine. One just has to look at the high numbers of people who die from hospital-acquired infections to realise that disinfection is not a concept which is really clear in human health care,” said Prof Bragg.

Much research has been done in the control of diseases through vaccination and through the use of antibiotics. “These pillars of disease control are, however, starting to crumble and more effort is needed on disinfection and bio security,” said Prof Bragg.

Prof Bragg has been working in close co-operation with a chemical manufacturing company in Stellenbosch to develop a unique disinfectant which his highly effective yet not toxic to the birds.

As a result of this unique product, he has developed the continual disinfection program for use in poultry. In this program the disinfectant is used throughout the production cycle of the birds. It is also used to ensure that there is excellent pre-placement disinfection.

“The program is extensively used for the control of infectious diseases in the parrot-breeding industry in South Africa and the product has been registered in 15 countries around the world with registration in the USA in the final process,” said Prof Bragg.

“Although the problem of plasmid mediated resistance to disinfectants is starting to rear its ugly head, this has allowed for the opening of a new research field which my group will hopefully exploit in the near future,” he said.
