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.

Lecture: THE BLACKNESS OF BLACK: Africa in the World Today

Audio of the lecture

Profile of Professor Ngugi wa Thiong'o (pdf format)

“Flowers are all different, yet no flower claims to be more of a flower than the other.” With these words Kenyan writer and one of the continent's most celebrated authors, Prof. Ngugi wa Thiong’o, delivered the tenth annual Africa Day Memorial lecture on 25 May 2012 in the University of the Free State's (UFS) Odeion Theatre on the Bloemfontein Campus. The lecture was hosted by the Centre for Africa Studies.

Long before Prof. wa Thiong’o was led inside the venue by a praise singer, chairs were filled and people were shown to an adjoining room to follow the lecture. Others, some on the university's Qwaqwa Campus, followed via live streaming.

In his speech titled the Blackness of Black: Africa in the world today, Prof. wa Thiong’o looked at the standing of Africa in the world today. He highlighted the plight of those of African descent who are judged “based on a negative profile of blackness”.

Prof. wa Thiong’o recalled a humiliating experience at a hotel in San Francisco in the United States, where a staff member questioned him being a guest of the hotel. He shared a similar experience in New Jersey, where he and his wife were thought to be recipients of welfare cheques. He said this was far deeper than overt racism.

“The certainty is based on a negative profile of blackness taken so much for granted as normal that it no longer creates a doubt.”

Prof. wa Thiong’o said the self certainty that black is negative is not confined to white perception of black only.

“The biggest sin, then, is not that certain groups of white people, and even the West as a whole, may have a negative view of blackness embedded in their psyche, the real sin is that the black bourgeoisie in Africa and the world should contribute to that negativity and even embrace it by becoming participants or shareholders in a multibillion industry built on black negativity.”

“Africa has to review the roots of the current imbalance of power: it started in the colonisation of the body. Africa has to reclaim the black body with all its blackness as the starting point in our plunge into and negotiations with the world.”

Prof. wa Thiong’o concluded by saying that Africa must rediscover and reconnect with Kwame Nkrumah’s dreams of a politically and economically united Africa.
