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.

Rev Jaftha heads interim steering committee on community engagement
2008-11-20

 
The group that attended the first meeting of the proposed National Community Engagement Managers’ Forum.
 Delegates, representing 13 higher educations institutions (HEIs) across South Africa, attended the first meeting of the proposed National Community Engagement Managers’ Forum in Stellenbosch.

Prof. Julian Smith, Vice-Rector: Community Interaction and Personnel of the Stellenbosch University (SU) delivered the keynote address “Consolidating community engagement at South African universities”. In his address he referred to the following: particularities of managing community service (CS) at HEIs, general management areas applicable to CS, the international and national impulses that pertain to CS, concepts and terminology and the lessons learnt, particularly in the case of SU.

Prof. Priscilla Daniels delivered a presentation on the Community-Higher Education-Services-Partnership (CHESP) initiative of the Joint Education Trust (JET) Education Services, as an important intervention in South African universities to support service-learning over the past ten years. Delegates had an opportunity to share their approaches to community service and community service learning as well as their challenges.

Steps were taken towards the establishment of a national forum for Community Engagement Managers. Issues that were discussed were the purpose, strategy, structure, relationship to other national and international structures as well as funding for community engagement initiatives at HEIs.

An interim steering committee, with Rev Kiepie Jaftha, Chief Director Community Service at the University of the Free State (UFS) as the convener, was elected to take the process further. The next meeting of the forum will be held at the UFS towards the end of March 2009.
