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.

It is always good to be honoured by your own university, but it is even more special to be honoured by another university, according to Prof Dap Louw, distinguished professor and forensic psychologist from the University of the Free State (UFS), on an award he received from the University of Johannesburg (UJ).

On 5 November 2015, Prof Louw received the prestigious Lifelong Achievers Award from the Department of Industrial Psychology and People Management at UJ in recognition of the major contribution he has made during his career in psychology. He was one of two recipients of the award during this year’s UJ Top Achievers Awards Ceremony.

Prof Louw had great appreciation for his students and colleagues at the UFS, without who he would have been “without arms”.

Worthy legacy

The Lifelong Achievers Award is presented to retired academics that have, over their careers, consistently made significant contributions to their field, nationally and/or internationally, and have left behind a worthy legacy.

According to the description for the award, the recipient has left behind a legacy in his or her specific field which is gratefully acknowledged by all past, present and upcoming professional colleagues, students, clients and other stakeholders.

This description concludes with: “We are a better science and profession because of you”.

Career full of highlights

Prof Louw is the author or co-author of over 100 articles in accredited national and international journals, and he is an accredited NRF researcher.

He is the principal author and editor of several textbooks currently prescribed by 12 universities in South and Southern Africa. It is estimated that, over the years, more than 100 000 students have received their training via textbooks he has written with his wife, Prof Anet Louw.

Prof Louw holds a master’s and doctoral degree in Criminology, and a master’s and doctoral degree in Psychology. He is the only person in South Africa with these qualifications.
During his career as forensic psychologist, Prof Louw has testified in many familiar criminal cases in South Africa and Namibia.

The Academy of Science of South Africa presented him with the Stals Award for Psychology and he was honoured by The National Honor Society in Psychology in the USA as well.
