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 acquires Willem Boshoff’s digital archive
2016-07-22

“I do not want to be the only person or artist that is part of this archive, but I want it to expand and involve others too.”

These were the words of Prof Willem Boshoff, the renowned artist and, Associate Professor in the Department of Fine Arts, during the presentation of the Willem Boshoff Archive to the University of the Free State (UFS) Johannes Stegmann Art Gallery during the Vrystaat Arts Festival.

The digital archive may be consulted at the Department of Art History and Image Studies. Large parts of it will also be available on the UFS website at http://scholar.ufs.ac.za.

Conversations surrounding the digital archive

In a discussion led by Dr Francis Halsall from the National College of Art and Design, Dublin, Ireland, the discussion led to the discovery of various themes, including The idea of research, education and dialogue, doing or making, the organisation of knowledge, language and translation, word and figures or people, and the enthusiastic amateur.

Artwork attracts international attention

Alongside Prof Boshoff and Dr Halsall, many other participants who have been inspired by the artist’s work sat in on the discussion about the archive.

They included Ivan Vladislavic, author of Willem Boshoff (2004), Dr Katja Gentric, whose doctoral dissertation at the University of Bourgogne (2013) is on Boshoff’s work, and Helene Smuts, arts education writer and publisher. Josef van Wyk, a Master’s student working on Prof Boshoff’s archive, and Prof Johann Rossouw, Associate Professor of the Department of Philosophy also formed part of the discussion.

Vladislavic mentioned that Prof Boshoff’s work opens up a different form of conceptualisation. “When I first encountered Willem’s work, I was excited by it from an art historic perspective,” he said.
