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.

A team of eight students from the Faculty of Law at the University of the Free State (UFS) will compete in an international arbitration competition in Vienna, Austria, from 30 March to 5 April 2007.

The Willem C. Vis International Commercial Arbitration Moot is an annual competition organised by the Institute of International Commercial Law at the Pace University School of Law in New York, USA. The goal of the competition is to foster the study of international commercial law and to train students in methods of alternative dispute resolution.

Students will be judged on two crucial phases: the preparation of memoranda for the claimant and respondent, and the presentation of oral arguments before an arbitral tribunal. “The Moot teaches the basic framework of international arbitration and the application of the uniform sales law to all participating students during the preparation of the memoranda and the oral arguments,” says one of the team members, Dee Leboela, who also took part in last year’s competition.

“This competition definitely prepares students for the legal practice in all facets, whether as advocate, legislator or other areas,” added Deman Smit, one of the team members who also took part last year.

This competition brings together students from a range of legal systems and cultures from all over the world to learn from the process and from each other. “This encourages the development of social competence, and lifelong skills that are needed in our profession, of which social relations play an important role,” says Leboela.

In its maiden participation last year the UFS did not disappoint, with the highest score of 49 out of 50 and the lowest being 38 out of 50. This year the UFS will compete with 178 universities from 51 countries. “With the right strategy, which involves selecting the students on academic merit and excellent advocacy skills, I believe we would make it to the top 32,” says Leboela with confidence.

The UFS team is Leboela, Smit, Lucien Companie, Vicky Olivier, Sunette Visser, Qaqamba Vellem, Hanno Bekker and Lucy Nthotso.
