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 (UFS) has become the first university in Africa to sign a memorandum of understanding with the United Nations University. The memorandum of understanding was negotiated by Mr Andries Jordaan, Director of the UFS's Disaster Management Training and Education Centre for Africa (DiMTEC).

Mr Jordaan negotiated with the United Nations University Institute for Environment and Human Security (UNU-EHS) to foster a relationship and combine their pool of resources for training in different aspects of Disaster Management. A triangular agreement between DiMTEC, UNU-EHS and the University of Novi Sad in Serbia will be established in three phases. The first phase is the signing of a memorandum of understanding between DiMTEC and UNU-EHS. This phase was completed in September 2009, when Prof. Konrad Osterwalder, Under-Secretary-General of the United Nations and Rector of the United Nations University, and Prof. Herman van Schalkwyk, Dean of the Faculty of Natural and Agricultural Sciences at the UFS signed the memorandum in Bonn, Germany. The second phase is a memorandum of understanding between UNU-EHS and the University of Novi Sad.

The memorandum of understanding entails among others joint projects between DiMTEC and the UNU-EHS, research for specific projects, exchange of lecturers and that the UNU will assist DiMTEC with external evaluation. As a result of this memorandum, the two universities have already combined their pool of resources by presenting a vulnerability short course and a visitation to the Republic of the Congo.
