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.

Kovsie community pledge to advance equality and eradicate racism

Speech by JC van der Merwe

On Monday 13 April 2015, the University of the Free State drew a line in history. Staff and students united in a singular vision: equality.

Since March 2015, the Institute for Reconciliation and Social Justice, together with the SRC, has launched the No-to-Racism/Yes-to-Equality Campaign across all three campuses with tremendous success. This campaign has now reached a high point at which the Kovsie community pledge their commitment to entrenching a culture of equality at the university. The first pledge ceremony took place on 13 April 2015 at the Bloemfontein Campus. Kovsies thronged to place their inked thumbprints on pledge posters in an inspirational show of solidarity.

“The key to transformation,” Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS, said, “is putting yourself in the shoes of the other person.” When you look past yourself and acknowledge others’ experiences, the world starts to look different. A pledge, Prof Jansen continued, is a solemn promise – not only to stop bad behaviour, but to go forward resolutely with good behaviour. “You do not change a campus, you do not change a country, without being courageous,” Prof Jansen said.

The message from Mosa Leteane, President of the Student Representative Council (SRC), echoed the same belief. “Today,” Leteane said, “the UFS takes a bold and courageous step toward equality.” This new generation, which includes young people from all races, has started a new revolution. A generation that says no to discrimination and yes to equality. “We cannot afford to be ignorant or indifferent,” Leteane urged.

The remaining two campuses will also have an opportunity to publically pledge their support on the following days:
Qwaqwa Campus: Wednesday 15 April 2015
South Campus: Friday 17 April 2015

To enable the university to go beyond dialogues and consultation towards active decision-making, a University Assembly will be held on Tuesday 28 April 2015. The assembly will serve as a space for critical engagement among all university stakeholders to focus on issues such as symbols, policies, practices, and curriculum. Staff and students are encouraged to submit matters for discussion to JC van der Merwe (vdmjc@ufs.ac.za) before 22 April 2015.

The No-to-Racism/Yes-to-Equality Campaign is aligned with the declaration made by the UFS Council in November 2014, in which it states that “the Council of the University of the Free State believes very strongly in the human dignity, equality, and freedom of all people.”
