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.

A researcher from the University of the Free State (UFS), Prof Johan Grobbelaar, was invited to join a group of scientists recently at the Institute for Bio- and Geo-Sciences of the Research Centre Jülich, in Germany, where microalgae are used for lipid (oil) production, and then converted to kerosene for the aviation industry.

The project is probably the first of its kind to address bio-fuel production from microalgae on such a large scale.  

“The potential of algae as a fuel source is undisputed, because it was these photoautotrophic micro-organisms that were fixing sunlight energy into lipids for millions of years, generating the petroleum reserves that modern human civilisation uses today.  However, these reserves are finite, so the challenge is marrying biology with technology to produce economically-competitive fuels without harming the environment and compromising our food security.  The fundamental ability that microalgae have to produce energy-rich biomass from CO2, nutrients, and sunlight through photosynthesis for biofuels, is commonly referred to as the Third-Generation Biofuels (3G),” said Prof Grobbelaar.

The key compounds used for bio-diesel and kerosene production are the lipids and, more particularly, the triacylglyserols commonly referred to as TAGs.  These lipids, once extracted, need to be trans-esterified for biodiesel, while a further “cracking” step is required to produce kerosene.  Microalgae can store energy as lipids and/or carbohydrates. However, for biofuels, microalgae with high TAG contents are required.  A number of such algae have been isolated, and lipid contents of up to 60% have been achieved.

According to Prof Grobbelaar, the challenge is large-scale, high-volume production, since it is easy to manipulate growth conditions in the laboratory for experimental purposes.  

The AUFWIND project (AUFWIND, a German term for up-current, or new impetus) in Germany consists of three different commercially-available photobioreactor types, which are being compared for lipid production.

The photobioreactors each occupies 500 m2 of land surface area, are situated next to one another, and can be monitored continuously.  The three systems are from Novagreen, IGV, and Phytolutions.  The Novagreen photobioreactor is housed in a glass house, and consist of interconnected vertical plastic tubes roughly 150 mm in diameter. The Phytolutions system is outdoors, and consists of curtains of vertical plastic tubes with a diameter of about 90 mm.  The most ambitious photobioreactor is from IGV, and consists of horizontally-layered nets housed in a plastic growth hall, where the algae are sprayed over the nets, and allowed to grow while dripping from one net to the next.

Prof Grobbelaar’s main task was to manipulate growth conditions in such a way that the microalgae converted their stored energy into lipids, and to establish protocols to run the various photobioreactors. This was accomplished in just over two months of intensive experimentation, and included modifications to the designs of the photobioreactors, the microalgal strain selection, and the replacement of the nutrient broth with a so-called balanced one.

Prof Grobbelaar has no illusions regarding the economic feasibility of the project.  However, with continued research, optimisation, and utilisation of waste resources, it is highly likely that the first long-haul flights using microalgal-derived kerosene will be possible in the not-too-distant future.

Prof Grobbelaar from the Department of Plant Sciences, although partly retired, still serves on the editorial boards of several journals. He is also involved with the examining of PhDs, many of them from abroad.  In addition, he assisted the Technology Innovation Agency of South Africa in the formulation of an algae-biotechnology and training centre.  “The chances are good that such a centre will be established in Upington, in the Northern Cape,” Prof Grobbelaar said.
