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 Free State Centre for Human Rights held a presentation by Prof Lungisile Ntsebeza on 7 September 2017 at the University of the Free State (UFS) Bloemfontein Campus on the topic of democracy and traditional leadership in rural areas. Prof Ntsebeza is the holder of the AC Jordan Chair in African Studies at the University of Cape Town and the holder of the National Research Foundation (NRF) Research Chair in Land Reform and Democracy in South Africa. 

Conflict between democracy and traditional rule
The topic of democracy and traditional leadership in the rural areas is an example of the tension between democracy and customary law governing the appointment of traditional leaders (headmen) that is currently at play in many parts of the country. Prof Ntsebeza made reference to a court case in the Eastern Cape, where a community successfully challenged the appointment of a headman by the royal family of the area. The contention was whether royal families could appoint headmen in rural communities or if those communities ought to democratically elect their own leaders. He argued that in this specific case, the democratic imperatives of the Constitution did not conflict with customary law because of the particular communal practice of electing leaders. 

The Constitution and customary law

The Constitution of South Africa recognises customary law provisions which are not in conflict with its fundamental values. Difficult legitimacy problems may arise where customary practices are different from those governing this particular case. Ultimately the Constitutional Court would be called upon to resolve inherent tensions and develop customary law in line with the direction foreseen in the Constitution.

Student engagement as a vehicle for change
The event was attended by UFS staff and fourth-year LLB students in the Faculty of Law, and was funded by the Free State Centre for Human Rights at UFS. The programme is one of several that the centre seeks to utilise in engaging students with researchers and scholars in the field of law and human rights. Prof Ntsebeza has given academic presentations on various related and trending topics in the current academic climate, such as decolonising the curriculum, Cecil John Rhodes and others. He was recently awarded the Hamilton Naki Award at the 2017 National Research Foundation Awards.
