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.

Teacher training key to democracy and freedom

Universities have the responsibility to respond to the challenges that the South African education system is faced with.

This is the view of the Free State MEC for Education, Mr Tate Makgoe, during his address at the three-day First Sustainable Rural Learning Ecologies (SURLEC) Colloquium, which was recently held at the Qwaqwa Campus of the University of the Free State (UFS).
 
“Our universities must not only research the failures of our system. They must also come up with solutions.
 
“One of the questions that demand answers in our country is whether we produce quality teachers at our universities, considering our learners’ performance internationally. Our children lack the basics like grammar and yet we are 17 years into democracy. Why is their performance so poor in comparison to children in poorer countries?” asked Mr Makgoe.
 
“We must work together as a Government and universities to change this. Universities must be anchors of democracy and freedom, which is meaningless if our children cannot read and write. We must also focus on Mathematics and Natural Sciences, not forgetting to value our indigenous knowledge and games to enhance learning, especially in Mathematics,” he said.
 
According to Dr Dipane Hlalele, Head of the Faculty of Education at the UFS Qwaqwa Campus, the colloquium was held to search for best practices and success stories relating to the theme, Creating sustainable rural learning ecologies in the 21st century.
 
“Our objective was to tap into experiences and wisdom of policy makers, researchers, scholars, teachers and students in order to map a new direction in research as well as to make an indelible mark on the revitalisation of this campus,” concluded Dr Hlalele.
 
The UFS Dean of Education, Prof. Dennis Francis’ efforts to improve rural education were honoured with the first ever SURLEC Award.
 
Over 70 research papers from the universities of the Free State, South Africa, Venda, KwaZulu-Natal, Limpopo and the Cape Peninsula University of Technology were delivered and learners from the local schools like The Beacon, Mafube, Qwaqwa and Clubview presented their winning projects at the Science Expo.
