With a 7% fiscal deficit on the Gross Domestic Product (GDP) projected by the National Treasury for the 2020/21 financial year, it would not take long to arrive at a dangerous level of debt at the rate that South Africa is borrowing. Although the South African Reserve Bank Governor, Lesetja Kganyago, does not consider a debt to GDP rate of 60% a disaster, he did express his concern regarding the country’s fiscal deficits being over 6% of the GDP.

Governor Kganyago presented a public lecture at the University of the Free State (UFS) on 4 March 2020, focusing on how we should use macro-economic policy and its role in our economic growth problem.

Unsustainable policies 
South Africa’s fiscal situation is not about tight monetary policy. According to the Governor: “Weak growth is endogenous in our fiscal problems. We cannot keep doing what we are doing and hope that growth will recover and save us. Growth is low, in large part, because of unsustainable policy.”

Avoiding an impending crisis
To address the problem, as a policymaker with more than 20 years’ experience, the Governor suggested that the recommendations made by Minister Tito Mboweni be taken into consideration. “The Minister of Finance, Tito Mboweni, is a man who says things that are true even when they are unpopular. His message is that we have to reduce spending and he is right to put this at the centre of our macro-economic debate,” said Governor Kganyago.

The state needs a radical economic turnaround strategy which is able to diminish the risk of losing market access and being forced to ask the International Monetary Fund for help. Governor Kganyago is positive that such a reformative tactic would go beyond monetary policy and ensure that the interest bill ceases to claim more of South Africa’s scarce resources.

UFS researchers are producing various flavour and fragrance compounds
2015-05-27

 

The minty-fresh smell after brushing your teeth, the buttery flavour on your popcorn and your vanilla-scented candles - these are mostly flavour and fragrance compounds produced synthetically in a laboratory and the result of many decades of research.

This research, in the end, is what will be important to reproduce these fragrances synthetically for use in the food and cosmetic industries.

Prof Martie Smit, Academic Head of the Department of Microbial, Biochemical and Food Biotechnology at the UFS, and her colleague Dr Dirk Opperman, currently have a team of postgraduate students working on the production of various flavour and fragrance compounds from cheap and abundantly available natural raw materials. 

Prof Smit explains that most of the flavours and fragrances that we smell every day, originally come from natural compounds produced mainly by plants.

“However, because these compounds are often produced in very low concentrations by plants, many of these compounds are today replaced with synthetically-manufactured versions. In recent times, there is an increasing negative view among consumers of such synthetic flavour and fragrance compounds.”

On the other hand, aroma chemicals produced by biotechnological methods, are defined as natural according to European Union and Food and Drug Administration (USA) legal definitions, provided that the raw materials used are of natural origin.  Additionally, the environmental impact and carbon footprint associated with biotech-produced aroma chemicals are often also smaller than those associated with synthetically-produced compounds or those extracted by traditional methods from agricultural sources.

During the last four years, the team investigated processes for rose fragrance, vanilla flavour, mint and spearmint flavours, as well as butter flavour. They are greatly encouraged by the fact that one of these processes is currently being commercialised by a small South African natural aroma chemicals company. Their research is funded by the Department of Science and Technology and the National Research Foundation through the South African Biocatalysis Initiative, the DST-NRF Centre of Excellence in Catalysis and the Technology Innovation Agency, while the UFS has also made a significant investment in this research.
