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 Helene Strauss delves into the emotion and politics of contemporary South African protest cultures
2014-12-22

Prof Helene Strauss from the University of the Free State’s (UFS) Department of English currently researches the relationship between emotion and politics in contemporary South African public and protest cultures.

The research foregrounds the complex set of concerns opened up by a study of intimacy, read as not simply a sign for emotional and sexual closeness, but more broadly as a complexly mediated site from which to observe the embodied, affective coordinates of various forms of control and contestation. Through the analysis of a range of cultural texts that, for instance, recompose moments of spectacular social upheaval through the lenses of everyday, embodied experience, this research considers what aesthetic responsibility might mean in both post-transitional South Africa and elsewhere.

One aspect of this research charts a gradual shift in South Africa from what is frequently referred to as the ‘liberation euphoria’ of the mid- to late 1990s – and the optimistic fantasies of a future South Africa that characterised dominant public discourse in the period immediately following the political transition – toward an emotional culture in which expressions of anger, disillusionment and disappointment seem to have become relatively widespread.

Prof Strauss asks, for instance, how these public feelings have been managed in the aftermath of events such as the Marikana massacre, and suggests that the affective and temporal dimensions of current attempts at containing perceived threats to financial and political stability on the part of South Africa’s business and political elite are key to understanding increasingly violent and repressive securitisation strategies.

Earlier this year, Prof Strauss presented papers on aspects of this research at two international conferences: (i) the Association for Cultural Studies conference in Tampere, Finland, where she was invited to be part of a ‘Spotlight Panel’ on the topic of African Cultural Studies, (ii) and at a conference at McMaster University in Hamilton, Canada, which she helped to co-organise.

An article based on some of this work has been published in the journal Safundi.
