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.

Fight against Ebola virus requires more research

Dr Abdon Atangana, a postdoctoral researcher in the Institute for Groundwater Studies at the University of the Free State (UFS), wrote an article related to the Ebola virus: Modelling the Ebola haemorrhagic fever with the beta-derivative: Deathly infection disease in West African countries.

“The filoviruses belong to a virus family named filoviridae. This virus can cause unembellished haemorrhagic fever in humans and nonhuman monkeys. In literature, only two members of this virus family have been mentioned, namely the Marburg virus and the Ebola virus. However, so far only five species of the Ebola virus have been identified, including:  Ivory Coast, Sudan, Zaire, Reston and Bundibugyo.

“Among these families, the Ebola virus is the only member of the Zaire Ebola virus species and also the most dangerous, being responsible for the largest number of outbreaks.

“Ebola is an unusual, but fatal virus that causes bleeding inside and outside the body. As the virus spreads through the body, it damages the immune system and organs. Ultimately, it causes the blood-clotting levels in cells to drop. This leads to severe, uncontrollable bleeding.

Since all physical problems can be modelled via mathematical equation, Dr Atangana aimed in his research (the paper was published in BioMed Research International with impact factor 2.701) to analyse the spread of this deadly disease using mathematical equations. We shall propose a model underpinning the spread of this disease in a given Sub-Saharan African country,” he said.

The mathematical equations are used to predict the future behaviour of the disease, especially the spread of the disease among the targeted population. These mathematical equations are called differential equation and are only using the concept of rate of change over time.

However, there is several definitions for derivative, and the choice of the derivative used for such a model is very important, because the more accurate the model, the better results will be obtained.  The classical derivative describes the change of rate, but it is an approximation of the real velocity of the object under study. The beta derivative is the modification of the classical derivative that takes into account the time scale and also has a new parameter that can be considered as the fractional order.  

“I have used the beta derivative to model the spread of the fatal disease called Ebola, which has killed many people in the West African countries, including Nigeria, Sierra Leone, Guinea and Liberia, since December 2013,” he said.

The constructed mathematical equations were called Atangana’s Beta Ebola System of Equations (ABESE). “We did the investigation of the stable endemic points and presented the Eigen-Values using the Jacobian method. The homotopy decomposition method was used to solve the resulted system of equations. The convergence of the method was presented and some numerical simulations were done for different values of beta.

“The simulations showed that our model is more realistic for all betas less than 0.5.  The model revealed that, if there were no recovery precaution for a given population in a West African country, the entire population of that country would all die in a very short period of time, even if the total number of the infected population is very small.  In simple terms, the prediction revealed a fast spread of the virus among the targeted population. These results can be used to educate and inform people about the rapid spread of the deadly disease,” he said.

The spread of Ebola among people only occurs through direct contact with the blood or body fluids of a person after symptoms have developed. Body fluid that may contain the Ebola virus includes saliva, mucus, vomit, faeces, sweat, tears, breast milk, urine and semen. Entry points include the nose, mouth, eyes, open wounds, cuts and abrasions. Note should be taken that contact with objects contaminated by the virus, particularly needles and syringes, may also transmit the infection.

“Based on the predictions in this paper, we are calling on more research regarding this disease; in particular, we are calling on researchers to pay attention to finding an efficient cure or more effective prevention, to reduce the risk of contamination,” Dr Atangana said.
