Opinion article by Prof Frikkie Maré, Department of Agricultural Economics, University of the Free State.
In William Shakespeare’s play Julius Caesar, Mark Antony utters the words: “Cry ‘Havoc!’, and let slip the dogs of war,” after learning about the murder of Julius Caesar. With these words he meant that chaos would ensue (havoc) to create the opportunity for violence (let slip the dogs of war).

The recent invasion (or military operation, according to Russian President Vladimir Putin) by Russian armed forces into Ukraine brought the famous words of Shakespeare to mind. Putin cried “Havoc!” and his troops created chaos in Ukraine. This is, however, not where it stopped because the dogs of war have been released into the rest of the world.

What is the impact on South Africa?

The day after the invasion we felt the bite of the dogs of war in South Africa. The rand suddenly weakened against the dollar, oil and gold prices increased sharply, and grain and oilseed prices on commodity markets increased 

This was before the rest of the world started to implement sanctions against Russia, which could be described as a shock reaction due to uncertainty as to how the situation would unfold. In the days after the initial market reaction we saw the markets actually “cool down” a bit, with most sharp initial reactions starting to change back to former positions. This period was, however, short-lived when the world hit back by closing airspace and borders and refusing to import products from Russia or export to them. The sanctions were in solidarity with Ukraine as an attempt to bring the Russian economy to its knees and force the Russians to withdraw from Ukraine.

Although the sanctions against Russia should certainly be successful over the long term, it does not change much in the short term and we will have to deal with the international effects of this conflict. The question then is, how will this affect South Africa?

Although there are no straightforward answers, as the impact will depend on what one’s role is in the economy. One thing for certain is that the total cost will outnumber the benefits. What affects everyone in South Africa, and the starting point of many secondary effects, is the increase in the price of crude oil. Russia is the second-largest producer of crude oil in the world and if the West is going to ban the import of Russian oil we will have an international shortage. Although the banning of Russian oil is the right thing to do to support Ukraine, it will have devastating effects on all countries in the world, with sharp increases in inflation.  

The increase in the price of oil not only drives up the cost of transportation of people and products, but also manufacturing costs. Fertiliser prices are correlated with the oil price, and it will thus drive up the production cost of grain and oilseeds.

Speaking of grain and oilseed prices, the Black Sea region (which includes Russia and Ukraine), are major exporters of wheat and sunflower seed and oil. The prices of these commodities have soared in international and South Africa markets over the past few weeks. Although it might seem like good news for our farmers, the increase in prices are offset by high fertiliser prices and the local shortage of fertiliser. This may lead to fewer hectares of wheat being planted this year in the winter rainfall regions.  

Nothing good is coming from this situation

In terms of agricultural commodities, both Russia and Ukraine are important importers of South African products, especially citrus, stone fruit and grapes.  Alternative markets now need to be found for these products which will affect prices negatively.

Although one needs to write a thesis to explain all the effects of the Russian-Ukraine conflict, the dogs of war have been slipped, and it is clear from the few examples that nothing good is coming from this situation. In short, we will see higher fuel prices (maybe not R40/litre, but R25 to R30/litre is possible), higher food prices, higher inflation and a higher interest rate.  

These factors affect all South-Africans, especially the poor and some in the middle class who will struggle in the short term. The time has come to cut down on luxuries and tighten belts to survive in the short term until there is certainty about how the havoc in Ukraine will play out.

Several industries in South Africa are currently producing hundreds of thousands of tons of carbon dioxide a year, which are released directly into the air. A typical family sedan doing around 10 000 km per year, is annually releasing more than one ton of carbon dioxide into the atmosphere.

The Inorganic Chemistry Research Group in the Department of Chemistry at the University of the Free State (UFS), in collaboration with the University of Zurich in Switzerland, has focused in recent years on using carbon dioxide – which is regarded as a harmful and global warming gas – in a meaningful way. 

According to Prof André Roodt, Head of Inorganic Chemistry at the UFS, the Department of Chemistry has for the past five decades been researching natural products that could be extracted from plants. These products are manufactured by plants through photosynthesis, in other words the utilisation of sunlight and carbon dioxide, nitrogen, and other nutrients from the soil.

Caffeine and chlorophyll 
“The Inorganic group is systematically researching the utilisation of carbon dioxide. Carbon dioxide is absorbed by plants through chlorophyll and used to make interesting and valuable compounds and sugars, which in turn could be used for the production of important new medicines,” says Prof Roodt.

Caffeine, a major energy enhancer, is also manufactured through photosynthesis in plants. It is commonly found in tea and coffee, but also (artificially added) in energy drinks. Because caffeine is a stimulant of the central nervous system and reduces fatigue and drowsiness, some people prefer decaffeinated coffee when enjoying this hot drink late at night. 

Removing caffeine from coffee could be expensive and time-consuming, but also environmentally unfriendly, because it involves the use of harmful and flammable liquids. Some of the Inorganic Group’s research focus areas include the use of carbon dioxide for the extraction of compounds, such as caffeine from plants. 

“Therefore, the research could lead to the availability of more decaffeinated coffee products. Although decaffeinated coffee is currently aromatic, we want to investigate further to ensure better quality flavours,” says Prof Roodt.

Another research aspect the team is focusing on is the use of carbon dioxide to extract chlorophyll from plants which have medicinal properties themselves. Chemical suppliers sell chlorophyll at R3 000 a gram. “In the process of investigating chlorophyll, our group discovered simpler techniques to comfortably extract larger quantities from green vegetables and other plants,” says Prof Roodt.

Medicines
In addition, the Inorganic Research Group is also looking to use carbon dioxide as a building block for more valuable compounds. Some of these compounds will be used in the Inorganic Group’s research focus on radiopharmaceutical products for the identification and possibly even the treatment of diseases such as certain cancers, tuberculosis, and malaria.
