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.

But do you forgive yourself, Eugene de Kock? asks Candice Mama

Candice Mama and her family met with her father’s assassin. Eugene de Kock. Prime Evil. Commander of the apartheid government’s covert Vlakplaas police unit. And what followed from this meeting was one of our country’s most poignant gestures of reconciliation. One by one, each family member expressed their forgiveness of De Kock, and soon afterwards, he was granted parole.

Candice recently visited the Bloemfontein Campus to talk about ‘An Unexpected Encounter with Eugene de Kock: A Journey of Transformation’. The event was a collaborative effort between the Institute for Reconciliation and Social Justice and Trauma, Forgiveness, and Reconciliation Studies.

“What makes it possible to cross the boundary from loss and pain to bond with the person who hurt you?” Prof Pumla Gobodo-Madikizela, asked Candice. “I had to educate myself about the when, where, and how, to get a context for Eugene de Kock,” she answered. With the encouragement of her mother, Candice became an avid reader from an early age. She devoured information, so that she could build a picture of this man within a specific historical and political context. What also contributed to this moment of reconciliation for her was De Kock humbling himself and taking full responsibility for his actions.

This meeting was not without inner conflict for Candice, though. “Why am I crying for hím?” she asked herself as she listened to him speak. “Why am I laughing?” she chastised herself as De Kock preened shyly for a group photograph with the family. “Is there something wrong with me to connect with him?” She questioned her values and beliefs. But instead of a monster, Candice saw the true essence of a repentant human being.

But how do you know he didn’t fake it, many people asked. Because it was “one of the most sincere and honest encounters I’ve experienced,” she said. During their meeting, Candice saw a man “crushed by the world”. Everything he believed as a young man, he realised, was a lie.

“Do you forgive yourself?” Candice asked the one question De Kock feared most. And in that moment, he was humanised for her. “When you’ve done the things I’ve done,” De Kock replied, “how do you forgive yourself?”
It remains an open question. But this act of forgiveness gives an entire country hope.
