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.

Faculty of Education discusses new curricula at summit
2012-03-07

 

Die Fakulteit Opvoedkunde se nuut-aangepaste B.Ed.-programme word binnekort by die Nasionale Departement van Hoër Onderwys en Opleiding ingedien vir herakkreditasie. Proff. Rita Niemann (links), Direkteur vir Nagraadse Studie en Navorsing, en Gawie du Toit, Direkteur vir Aanvanklike Onderwysersopvoeding, is aan die stuur van die herkurrikuleringsproses vir voorgraadse en nagraadse programme van die Fakulteit Opvoedkunde.

The training of professional teachers rests on a strong curriculum. For this reason, the Faculty of Education has been re-looking at the curricula of the B.Ed. programme for the past two years.

Before this programme is submitted for approval and accreditation, the Education Faculty’s staff from the Bloemfontein and Qwaqwa Campuses will attend a summit at the Gariep Dam on 7 and 8 March 2012. This summit is a sequel to guidelines drawn up by the National Department of Higher Education and Training on adjusted requirements for teacher training. It determines that all initial teacher training and honours programmes be recurriculated and resubmitted for accreditation. These requirements were published in the Government Gazette in July 2011 and involve all education faculties in the country.
 
Deans and line heads of other faculties, including Natural and Agricultural Sciences, Humanities, and Economic and Management Sciences, have also become involved as Education students often register for modules in these faculties.
 
Last week a team from the UFS’s Education Faculty also attended a workshop presented by the Council on Higher Education where the criteria for recurriculation and the evaluation of programmes were discussed.
 
Prof. Gawie du Toit of the UFS’s Faculty of Education says curriculation is not merely a technical process but requires thorough reflection and conceptualisation, involving various roleplayers.
“It is important that recurriculation should take place over a period of time to allow for sufficient time for reflection, absorption and ownership.”
 
Thus, the aim of the Gariep Dam summit is to introduce a teachers’ training program that will provide graduates with the necessary knowledge, skills and responsibilities to take up their places as academics and professional beginner teachers.
 
During these two days students in Education will not attend any classes but they are tasked with self study and to complete assignments.
