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.

Students excel in legal interpreting programme

A success rate of 90% was achieved by the first group of 100 students that successfully completed the two-year Diploma in Legal Interpreting at the University of the Free State (UFS).

The group recently received their diplomas at the ceremony held on the Main Campus in Bloemfontein.

The programme, offered by the university’s Department of Afroasiatic Studies, Sign Language and Language Practice, in collaboration with the Department of Justice and Constitutional Development and Safety and Security Sector Education and Training Authority (SASSETA), is the only one of its kind in South Africa.

“The numbers that we are talking about here, if one looks at the needs of the country as such, is a small fraction,” said Advocate Simon Jiyane, Deputy Director General: Court Services in the Department of Justice.

“This is our first programme in collaboration with the UFS and I am hopeful it will lay a very solid foundation for other such programmes to follow.”

The diplomas were conferred by Prof. Ezekiel Moraka, Vice-Rector: External Relations at the UFS, on behalf of the Rector and Vice-Chancellor, Prof. Jonathan Jansen.

He urged the students to use their skills as qualified court interpreters in the context of the challenges that face South Africa such as HIV/Aids, racism, transformation, unemployment, poverty, job losses, and many other such challenges.

“This is the reality we are faced with, all of us,” he said. “It requires skilful and morally upright people to address it adequately and effectively. You are adding up to the number of skilful people in our country and that means you have a critical role to play.”

He said the UFS, as a societal structure, is equally affected by those challenges because of being accountable to and economically dependent on society.

He also urged the students to use their skills to make contributions to the processes of transformation that are underway at the UFS.

“For instance, the UFS as a national asset has to transform to that level of being a true national asset. We need your full participation in this process so that we can together ensure the relevance of this university as a true South African university,” he said.

Advocate Jiyane urged universities to also look at some of the initiatives that the government takes to improve service delivery. One such initiative is a pilot project focusing on the use of indigenous languages in courts.

“Its aim is to ensure that our courts begin to recognise all official languages in terms of conducting their business,” he said.

“It is our responsibility as a department that, through this project, we begin to build those languages so that they are on a par with the other languages that are being utilised in our courts.”

The department has permanently employed two of the students who received their diplomas, while one of them, Ms Nombulelo Esta Meki, was awarded a bursary by SASSETA to study for a BA in Legal Interpreting. Ms Meki was the top achiever of the programme with an average of 86%.
