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.

Architecture gets unconditional validation
2012-10-15

 Three programmes of the Department of Architecture at the university received an extended unconditional validation from the South African Council for the Architectural Profession (SACAP) and the Commonwealth Association of Architecture (CAA).

The programmes are evaluated every four years and the previous evaluation in 2008 was also unconditional. The programmes that were validated are BAS, BAS (Hons.) and M.Arch. (Prof).

Mr Jonathan Manning, chairperson of the board of eight people that visited the department, says the department’s standards have improved more since the previous visit. He expressed his apprectiation for the departement’s unique specialist approach to alternative building methods, tours, winter schools, the annual Sophia Gray lecture, the good team of lecturers and the impressive Architecture building.

Two members of the board who visited the department are from the CAA.

Mrs Martie Bitzer, Departmental Chairperson, says the validation proves that the programmes are not only recognised nationally but also internationally. “It confirms that the students are at the right place at the right time in terms of the vision of the UFS, namely to be an internationally recognised university.”

The validation of the CAA means that the qualifications are recognised in all the Commonwealth countries.
