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.

Prof Annie van den Oever envisions the future of film and visual media in her inaugural lecture
2014-02-07

The university formally welcomed Prof Annie van den Oever, an internationally-recognised film and media scholar, within its academic ranks. Her association with the UFS forms part of an exciting new postgraduate programme in film and visual media being created by the Faculty of the Humanities.

Prof Annie van den Oever delivered her inaugural lecture, “Foundational Questions for a Film and Visual Media Programme”, sharing her extensive knowledge in the field. The lecture attracted an international audience with people following the talk via live streaming from places such as Oslo, Berlin and London.

“Annie is quite a connected person through the film and visual media world,” Prof Lucius Botes, Dean of the Faculty of the Humanities, told the audience in the CR Swart Auditorium. He also referred to the fact that, under the auspices of Prof Van den Oever, two staff members from the faculty completed their master’s degrees at the University Groningen where she also teaches. “I am happy to announce that through Annie’s network we can invest in these young people.”

Prof Suzanne Human, Head of the Department History of Art, applauded the senior leadership for its vision to appoint Prof Van den Oever as extraordinary professor. “We have profoundly benefited and will still benefit from Annie’s obvious enjoyment in sharing her considerable experience and expertise in the design of a programme of film and media studies.”

The new postgraduate programme in film and visual media is being developed in partnership with the departments of Art History and Visual Culture Studies, Drama and Theatre Arts, English and the Department of Afrikaans, Dutch, German and French. The university aims to have the first film students enrol in 2015.
