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.

“The project is special because it is an event in the community, by the community.” This is what Gerda Pretorius, lecturer in the Odeion School of Music (OSM) at the University of the Fee State, said about the second music concert hosted by the OSM in Heidedal, Bloemfontein.

The concert, in collaboration with the Reach Our Community (ROC) Foundation on 26 November 2016, was a follow-up on the concept that was started last year. As part of the outcomes of the MUSE3706 module, the third-year Music Education students engage in a project in a specific environment.  For this project the MUSE team, led by Pretorius and Anchen Froneman, collaborated with the ROC Foundation in Heidedal. Two third-year students in the OSM, Sehle Mosole and Jonandrea Pofadder, facilitated the event in 2016.

Long relationship between ROC and UFS

Since 2008, the UFS has successfully partnered with ROC through service-learning and community-engagement projects in which students from across all seven faculties participate. The foundation strives to address the challenges resulting from factors such as poverty, unemployment, HIV/Aids, single parenting, lack of guardianship, and physical and sexual abuse. In the Afterschool Care programme, the children engage in educational, cultural, and recreational activities.

Children who form part of the foundation’s Afterschool Care programme, showed their impressive music skills to their parents and guardians in attendance.

Spontaneous participation by community

“I was deeply touched by the spontaneous participation and appreciation of the community for art-related – in particular music and dance – events,” said Pretorius. A highlight was the community’s involvement in the event and the value it adds to the students’ organising skills.
