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.

UFS awards honorary doctorate to Archbishop Emeritus Desmond Tutu
2011-01-01

Archbishop Emeritus Desmond Tutu

The University of the Free State (UFS) will reach a milestone in its history today when an honorary degree, the Doctor of Theology, will be conferred on Archbishop Emeritus Desmond Tutu.

At the same event Archbishop Tutu will launch the university’s International Institute for Studies in Race, Reconciliation and Social Justice.
 
The idea of the establishment of such an institute originated after the Reitz incident in 2008. In 2009, during his official inauguration, Prof. Jonathan Jansen, Vice-Chancellor and Rector, embodied this idea when he stated that the university would be an example of a place where reconciliation, forgiveness and social justice would not only be studied, but where it would also be applied in practice. “Students and scholars from across the world will come to the UFS to study the theory and practice about the building of societies across the boundaries of race, as well as religion, gender, disabilities and national origin,” Prof. Jansen said.
 
The institute is a critical intellectual space where engaged scholarship, public discussion, community engagement and contextually relevant teaching are innovatively harnessed towards exploring and finding solutions to the complex and challenging work of social transformation in South Africa,” says Mr John Samuel, Interim Director of the institute. Mr Samuel was the former Chief Executive Officer of the Nelson Mandela Foundation.
 
According to Mr Samuel, the institute seeks to establish itself as a premier international site for research on race, reconciliation and social justice. “We want to link the manifestations of race in higher education, to the related matters of reconciliation and social justice in the South African context against the backdrop of racial and ethnic conflicts elsewhere in the world,” says Mr Samuel.
 
The institute will, amongst others, publish groundbreaking research, organise national and international conferences about reconciliation and social justice, as well as contribute to the establishment of national and international networks that are actively involved in matters relating to race, reconciliation and social justice. Through its research, the institute will endeavour to understand the challenges facing the UFS better, as well as how to address these challenges. For this reason, the concept of the UFS as a “live laboratory” and the use of evidence-based practice remain important for the university.
 
By honouring Dr Tutu, the UFS recognises the contribution that Dr Tutu has made in the field of Theology through his teachings and the books he has written. However, the UFS is not only honouring him as a moral and religious leader who has maintained his integrity as a Christian. “We honour a great son of South Africa who has made a huge contribution to peace, reconciliation and justice in South Africa and in the world,” says Prof. Jansen.
 
The unveiling of the new corporative brand of the UFS will render further lustre to the day.
