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.

New Research in Hebrew Language and Culture
2014-01-17

The newly formed Department of Hebrew at the university is hosting an international conference from 27 to 29 January 2014. The conference has speakers from Israel, the United States, Canada, the United Kingdom and Saudi Arabia, as well as South Africa, Zambia, Congo and Nigeria. The goal of the conference is to highlight recent research in Hebrew language and culture by bringing international scholarship to the university and by highlighting the importance of the African context as a conceptual space for research on Hebrew. The rich cultural heritage of Hebrew finds particular resonance in Africa through the Hebrew Bible (Old Testament).

Some highlights from the conference include new research on the use of the ancient Hebrew script by Jews in the Persian and Roman periods as a means to maintain their religious and ethnic identity in times of distress, linguistic research on metaphors in the Hebrew Bible (Old Testament), Jews and non-Jews in the Hebrew and Yiddish writings of the South African author Morris Hoffman, the development of a rabbinic prayer for rain in the land of Israel and in South Africa, pedagogical advances in teaching Hebrew in Africa, and translation of the Hebrew Bible (Old Testament) as a means of reshaping VaTsonga cultural identity. 

The study of ancient and modern Hebrew language and culture provides important insights into the complex cultural situation in modern Africa, generally, and South Africa, in particular. The use of language by minority religious and ethnic groups can provide a powerful force for identity in turbulent political realities. Religious texts can be re-contextualised to provide guidance in new cultural contexts or translated to enhance and empower local societies. 

Venue: CR Swart Auditorium
