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 University of the Free State, takes pride in the gold PRISM Award (from the Public Relations Institute of Southern Africa) for the B Safe Take Action safety campaign that has been rolled out on the campus since 2013 by the Department of Communication and Brand Management.

The campaign earned the Von H Brand Provocateur gold award in the internal communication category.

“The UFS is the only tertiary institution to receive a gold award. The award is a great honour for the department, considering the cream of South African public relations took part in the competition, and the standard was naturally very high. It was also a feather in the cap for us that the uniqueness of the campaign received national recognition from our peers in this manner, said Ms Lacea Loader, Director: Communication and Brand Management at the UFS.

The university is responsible for about 32 000 students and 4 000 members of staff on its three campuses: the Bloemfontein and South Campuses in Bloemfontein and the Qwaqwa Campus in the Eastern Free State. It is of cardinal importance for the university that its students, staff, and assets are safe.

Apart from safety measures that have been implemented by the UFS Protection Services, the B Safe Take Action campaign has also been rolled out on the three campuses of the UFS. The campaign supports the safety strategy of the university. It is aimed at developing a culture of safety awareness in students and staff alike. The purpose of the campaign is for staff and students to take ownership of their own safety. In addition, it creates awareness of the safety measures that are in place at the UFS.

The campaign has been rolled out on various communication platforms. These include placards, pamphlets, lamp-post advertisements, an advertisement board, emails, and messages on student communication portals such as Blackboard, the UFS web and intranet, social media, information boards in the campus parking areas and on the pedestrian walkways as well as messages on refuse bins around the campus. “The fact that a variety of communication platforms has been deployed, the striking design and character of the messages, and the number of target audiences that have been reached further contributed to the success of the campaign,” said Ms Loader,

The campaign also received a merit award from the International Association for Business Communication (IABC). The award will be presented on 15 June 2015 in San Francisco, USA.
