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.

Student rights revived
2015-03-30

Lindokuhle Ntuli fulfils his promises.

“I can assure you that each and every promise that I’ve made to the students will be fulfilled.”

That is a promise that Lindokuhle Ntuli, SRC Legal and Constitutional Affairs (Bloemfontein Campus) gave to Kovsie students. The fourth-year LLB student and founder of the UFS Legal Behemoth describes himself as an ambitious person with a passion for law, order, and formality.

He explains the duties of his portfolio as “the office that will really ensure that the interests of all students are catered for. That student’s consumer rights are respected and not violated.” Through his portfolio, he aims to make sure that students are aware of what their rights are.

As part of his portfolio, Ntuli has re-introduced the Student Court, which will be fully functional during the second semester. The portfolio also introduced the Student Engagement Forum.  The purpose of the forum is for students to share their grievances with regards to student rights violations. These discussions will take place twice a semester.

“The student engagement forum is the means by which we are able to really assess what kind of rights of the students are being violated,” Ntuli added.

Together with Louzanne Coetzee, SRC Accessibility and Student Support, Ntuli aims to establish the Student Rights Desk. The desk will deal directly with student rights on campus without recourse to the student court or external courts.

When asked about what his vision for the SRC is, Ntuli responded:

“My vision for the SRC is to see the SRC really attending to each and every need of students. We must advocate for students in the best way we can.”

And the words Lindokuhle lives by?

“Law and order exist for the purpose of establishing justice, and when they fail in this purpose, they become the dangerously structured dams that block the flow of progress” (Martin Luther King Jnr).
