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.

UFS Vice-Chancellor’s vision for 2016: R100 million before September

At the official opening of the University of the Free State (UFS), held on 19 February 2016 on the Bloemfontein Campus, Prof Jonathan Jansen, Vice Chancellor and Rector, announced that his priority for the year is to raise R100 million. Deserving students who cannot afford to study will receive bursaries through the Student Bursary Fund Campaign.

Staff will also have the opportunity to contribute to the fund.

Prof Jansen thanked staff for their hard work in the midst of what he described as “by far the most difficult year for admissions, registration, accommodation, and student finance”. The heightened expectations of students after FeesMustFall and the limited capacity of the university to meet the desires of students took its toll on staff.

Because of the incredible strain taken by staff members, both emotionally and physically, the Vice-Chancellor gave staff the assurance that they will receive spiritual, emotional, and health support.

“Never before have I seen such dedication from all our staff to hold the university together in these trying times,” Prof Jansen said.

“Because of you, we have a record intake of first-year students into the UFS. We have had about 5 000 students on average in the past three years and, as of today, we are nearing 7000 first-years with the strong possibility that we will enroll several thousand more students, once the new South Campus registrations come on line later this year. By mid-2016, we will exceed our own target of 8 000 students,” said Prof Jansen.

He stipulated that it is not only good for the finances of the university but also for the youth of the country who can access a quality university in central South Africa where the safety of its staff and students is a priority.

Another highlight at this event was announcing Dr Christian Williams from the Department of Anthropology as the winner of the 2016 Distinguished Scholar Book Prize for his book, National liberation in postcolonial southern Africa: a historical ethnography of SWAPO’s exile camps.

Amidst the sad episodes of violence and destruction on campuses around South Africa, Prof Jansen highlighted how the UFS will – through a seven-point approach - manage the university during these difficult times:
1.    Doing everything within our capacity to meet the needs of staff and students
2.    Upholding the right to peaceful protest in our democracy
3.    Acting swiftly against any unlawful actions by students or workers
4.    Upholding the authority of the unions (only UVPERSU and NEHAWU)
5.    Finding humane and just solutions to the problem of outsourcing
6.    Not placing the UFS at financial risk by making irresponsible decisions
7.    Maintaining an open door policy.
