Dr Frikkie Maré is serving as one of the directors of the non-profit organisation, the Agri Relief Foundation (ARF).

The agricultural sector is used to facing events of abnormal impact, including floods, droughts, veld fires, and disease outbreaks. Even if it is possible to prepare against any of these risks by taking proper measures, for instance by having a farm emergency plan in place or by securing property properly, there are times when it is not possible or practical for the modern-day South African farmer to proactively manage all the risks they are facing.

It is in times like these that the newly established body, the Agri Relief Foundation (ARF), provides an invaluable service to the agricultural sector. 

Dr Frikkie Maré, Senior Lecturer in the Department of Agricultural Economics at the University of the Free State (UFS), is one of the directors of this non-profit organisation, which focuses on assisting agricultural producers in need. 

This initiative is the brainchild of a number of businesses in the agricultural sector.

He says although there are many institutions in South Africa assisting farmers, most of the current initiatives are geared towards large-scale disasters, such as severe droughts, floods, unpreventable pests and diseases, and veld fires that affect many producers.  

Benefiting the wider society

According to Dr Maré, the ARF will focus on helping individual agricultural producers who are in need; both financially and otherwise.  This may include elements such as the loss of grazing due to brown locust, assistance after a farm attack or murder to ensure the day-to-day running of the farm, and localised natural disasters such as floods, hail, severe cold, or fire.

The group of directors plays a key role in screening the applications for assistance and deciding, based on merit and the availability of resources, who they can assist.

Besides the direct benefit to the farmer, this initiative also adds value to the wider society. “When the sustainability of an agricultural producer is under threat, it also threatens the livelihoods of his/her workers and their families, the rural economy of the nearest town where they purchase production inputs and general groceries, as well as society at large, as less food and/or fibre will be produced.  The assistance of the ARF will therefore ripple out to a much larger level than only the agricultural producer,” explains Dr Maré. 

A learning experience

There is also a benefit for the university. In the classroom, Dr Maré will be able to share any knowledge he is gaining in this process with his students. “Agricultural Economics is fundamentally about ensuring the long-term sustainability of agricultural production through concepts, including but not limited to, production economics, natural resource economics, agricultural management, and marketing.  My involvement in the ARF will provide examples of what can go wrong in terms of primary production that threatens the sustainability of the enterprise and what can be done to assist,” he says. 

Any business or individual can contribute to this noble cause. Financial contributions as well as physical products such as transport, fuel, animal feed, and legal services are welcome. 

Dr Maré says they have already received contributions from companies such as Zoetis (animal health), which sponsor a part of their profit from certain products to the foundation on a continuous basis. Lavendula (animal feed) also sponsored the proceeds of a farmers’ information day.

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.
