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.

‘Leadership is formed through ethical behaviour’
2012-08-20

Mr Edward Kieswetter
20 August 2012

“Being ethical is not about what we can do, it is about what we ought to do.” This is according to Mr Edward Kieswetter, Group Executive of Alexander Forbes Limited. During his lecture to MBA students in the Business School, Mr Kieswetter allowed the audience to engage in a discussion about ethics and leadership in the business world. Mr Kieswetter is also Vice-Chairperson of the UFS Council.

Part of the lecture was discussing South Africa as a country that was not born in ethics. Mr Kieswetter commented that although context was is very important in making decisions, South African people tended to, for example, and “feed on corruption, instead of acting actively against it”. Questions about South Africa’s ethical foundation were raised. Mr Kieswetter explained that one of the greatest challenges with the South Africans was to help them understand that a person always had a choice. “If you have to compromise on your own values, you are not doing anybody justice.”

Ethics can promote common and social goals if they are not determined by what people feel and strive to reach beyond the barriers that religious beliefs put up. He shared of his life’s most valuable lessons learned about people in leadership positions. “A great leader has incredible self-awareness and displays a huge amount of humility.” He said that in life it was not about being perfect; it was rather about being authentic, even in challenging times where the outcome might affect the current situation negatively. “My greatest successes came from lessons I learned in making mistakes and growing from them.

“If you have nothing to die for, then what is there to live for?” Mr Kieswetter said when asked whether he would compromise his financial position if he did not agree with the ethics of the company he worked for. “By constantly complaining instead of progressing, we are giving up our power to change, and that is a scary thing for South Africa as a developing country.”
