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.

Prof Beatri Kruger conducts research on modern-day slavery

Representatives of the US Embassy in South Africa and other stakeholders gathered in Bloemfontein in November 2014.

Human trafficking is a multi-billion dollar ‘business’ with daunting challenges because of the uniqueness and complexities involved in the crime, says Prof Beatri Kruger, ex-prosecutor and lecturer in Criminal Law in the Faculty of Law.

Prof Kruger’s on-going research concentrates on whether South Africa’s legal efforts to combat human trafficking complies with international standards set out in the United Nations Trafficking Protocol of 2000 and other relevant international treaties.

Since the completion of her studies, the Prevention and Combatting of Trafficking in Persons Act of 2013 was passed in Parliament, but needs to be promulgated. This means South Africa is still a long way from complying with the UN protocol. A delegation of the US Embassy in South Africa recently visited the Faculty of Law on the Bloemfontein Campus. The purpose of their visit was to gain information for the US Department of State’s comprehensive 2015 report on trafficking in persons.

Prof Kruger’s current research focuses on the new legislation in collaboration with other national and international stakeholders. One of the focus areas is how traffickers control their victims. This research enhances the understanding of why victims often do not seek help, do not want to be ‘rescued’ and why they return to the very traffickers who have brutally exploited them.

The recently released Global Slavery Index 2014 estimates that 36 million people are living as slaves worldwide and that 106 000 of them are in South Africa. This report states that ‘modern slavery’ includes human trafficking, forced labour, forced marriage, debt bondage and the sale of children. The International Labour Organization estimates the illicit profits of forced labour to be US $150 billion a year.
