Marcele Vermeulen, a graduate from the Department of Plant Sciences, explores possible threats to crop production; contributing to food security in South Africa.

Global food security is currently threatened both by climate change and the low diversity of crops relied on by humankind to feed a growing world population. Marcele Vermeulen, a graduate in the Department of Plant Sciences who will receive her PhD at the December graduation ceremonies at the University of the Free State (UFS), is part of a team that is working hard to add to the diversity of staple foods in South Africa.

In the drive to focus on alternative crops, Marcele is researching the crop, Amaranthus cruentus, (grain amaranth). It is more tolerant to environmental stress for large-scale production, thereby also diversifying staple crops.

Relatively new development

“Amaranthus cruentus is an excellent candidate due to its high nutritional value and tolerance to drought and high temperatures. It can be mixed with conventional maize meal, to increase the protein intake of its consumers,” said Marcele.

The production of A. cruentus as a grain crop in South Africa is a relatively new development.

In her research, exploring the possible threats to crop production and paying particular attention to dominant plant pathogens in the Amaranthus cruentus, Marcele found a correlation between fungal pathogens and insect pests. 

Insect pests can influence plant diseases

Although reports on fungal pathogens and pests specific to A. cruentus are limited to and information for South Africa is limited to this study, there is a possibility that by controlling insect pests such as weevils, one might also be able to control fungal pathogens of Amaranthus cruentus.

Marcele believes that control of weevil pests should thus be the focus of future pest and pathogen management strategies and breeding programmes in A. cruentus.  

“Knowledge gained in my thesis will hopefully aid in the development of future cultivation practices, integrated pest/pathogen management programmes, as well as for the registration of crop protection products for A. cruentus,” Marcele added.

Meet our Council: Ndaba Ntsele – Inspiring entrepreneurs

 To call Mr Ndaba Ntsele just a businessman seems like a bit of an understatement. The Executive Chairman and co-founder of Pamodzi Group Limited lives and breathes business, entrepreneurship, and wealth creation. He is also a member of the Council of the University of the Free State (UFS) since September 2013.

His greatest passion is entrepreneurship, and sharing his ideas of self-employment with young (and old) South Africans. “I preach self-employment wherever I go. Everyone knows that unemployment is a major problem in our country. However, people often expect the government or big corporations to provide them with jobs. I like to influence people to start thinking about working for themselves, thereby creating opportunities for employing others,” he says.

His entrepreneurial drive extends even to his time on the UFS Council. Now in his second term, Mr Ntsele has been well placed to get a sense of the kind of contribution the university and its students could make to South Africa, and even further afield.  

“In addition to training students for all the other important industries in South Africa, I think the UFS is ideally situated to create agricultural entrepreneurs. The Free State is one of South Africa’s prime agricultural areas, after all. Food security is an issue worldwide, and it is an area in which we could make a real contribution by training food producers, food technologists, and agricultural specialists. In fact, I think the UFS could become the leading agricultural institution in the country.”

Being the best is something that he strives for continually, while high standards are not something he shirks. In fact, he believes that Council members should hold an institution accountable for maintaining the highest standards possible, whether it is in governance, financials, procurement, or any other areas of importance in an institution.

As the executive chairman of a multi-billion African-owned group with assets across the globe, Mr Ntsele does not have a great deal of free time. However, he enjoys sitting down with MBA students and graduates to share his views about entrepreneurship.

“If I can change their mind-set from ‘others must employ me’ to ‘I need to create my own employment’, then I will feel as if I have accomplished something,” he says.
