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 TRC legitimised apartheid - Mamdani
2010-07-20

 Prof. Mahmood Mamdani
“The Truth and Reconciliation Commission (TRC) accepted as legitimate the rule of law that undergirded apartheid. It defined as crime only those acts that would have been considered criminal under the laws of apartheid.”

This statement was made by the internationally acclaimed scholar, Prof. Mahmood Mamdani, when he delivered the Africa Memorial Lecture at the University of the Free State (UFS) last week on the topic: Lessons of Nuremberg and Codesa: Where do we go from here?

“According to the TRC, though crimes were committed under apartheid, apartheid itself – including the law enforced by the apartheid state – was not a crime,” he said.

He said the social justice challenges that South Africa faced today were as a result of the TRC’s failure to broaden the discussion of justice beyond political to social justice.

He said it had to go beyond “the liberal focus on bodily integrity” and acknowledge the violence that deprived the vast majority of South Africans of their means of livelihood.

“Had the TRC acknowledged pass laws and forced removals as constituting the core social violence of apartheid, as the stuff of extra-economic coercion and primitive accumulation, it would have been in a position to imagine a socio-economic order beyond a liberalised post-apartheid society,” he said.

“It would have been able to highlight the question of justice in its fullness, and not only as criminal and political, but also as social.”

He said the TRC failed to go beyond the political reconciliation achieved at Codesa and laid the foundation for a social reconciliation. “It was unable to think beyond crime and punishment,” he said.

He said it recognised as victims only individuals and not groups, and human rights violations only as violations of “the bodily integrity of an individual”; that is, only torture and murder.

“How could this be when apartheid was brazenly an ideology of group oppression and appropriation? How could the TRC make a clear-cut distinction between violence against persons and that against property when most group violence under apartheid constituted extra-economic coercion, in other words, it was against both person and property?”, he asked.

“The TRC was credible as performance, as theatre, but failed as a social project”.

Prof. Mamdani is the Director of the Institute of Social Research at the Makerere University in Kampala, Uganda; and the Herbert Lehman Professor of Government in the Department of Anthropology at the Columbia University in New York, USA.
