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.

Dr Mercy Oduyoye receives an honorary doctorate for changing how women are viewed in theology

Dr Mercy Amba Oduyoye received an honorary degree from the UFS Faculty of Theology in acknowledgement of the trailblazing work she has done in the field of African women’s theology. Known as the Mother of African Women’s Theology, Dr Oduyoye is the first black woman in Africa to have received a degree in theology. Ever since then, she has been changing views on gender in theology across the globe. Still at the office at the age of 82, Dr Oduyoye’s life work has centred on two areas: her work with churches, and her work with female theologians.

Women in religion and culture
Following the 2015 Winter Graduation Ceremony on the Bloemfontein Campus, during which Dr Oduyoye received her honorary degree from the University of the Free State (UFS), she presented a lecture on women in religion and culture at the Faculty of Theology. Dr Oduyoye gave a brief overview of her involvement in organisations since the early 1970s to eliminate patriarchal structures in theology, in order to produce a relationship of partnership between women and men. An area that lies especially close to Dr Oduyoye’s heart is that of storytelling, and the use of language. Therefore, a driving force behind her work has been the question: “How do we communicate what we believe as Christians?”

Writing in a way people can understand

This question led Dr Oduyoye on her journey to vernacularise theological language, and it became her mode of writing. “Very seldom will you find the classical or official theological language in my writing, because I’m writing as if I’m speaking to a youth group, a women’s group – or even my grandmother.” In this way, communication became her focal point to present Christianity in such a way that people can understand it, thus rendering it relevant to the situation in Africa.

Changes toward inclusive language
Dr Oduyoye has gone on to author four books and over eighty articles on theology from a feminist perspective. And after toiling for many years, Dr Oduyoye can now see the changes emerging – especially in the US – as Bibles, lectionaries, and hymns are increasingly adopting an inclusive language, giving women a presence and voice within the church.
