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.

Construction of two new residences on our Bloemfontein Campus will begin soon. Some 500 students will be accommodated in the residences, with the first students able to move in from January 2013.   

The premises where the residences will be built were recently handed over to the contractors.

Mr Rudi Buys, Dean of Student Affairs, says that the design of the residences follow global trends in student accommodation, but are adapted to local needs and student communities. The new residences will provide more study and tutoring spaces, also with more open space for diverse students to socialise. The residences will function together as a Student Life College.

Mr Quintin Koetaan, Director: Housing and Residence Affairs, says the new residences will house both junior and senior students. Residences will co-ed, with men and women housed in separate and secure passages.
 
The planned construction of student accommodation includes five new residences – four on the Bloemfontein Campus that will provide 1000 beds and one on the Qwaqwa Campus with 250 beds. This will provide for the increasing need for student accommodation. The project will be completed in two phases. Phase one commenced in Bloemfontein on 21 February 2012.
