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 Central University of Technology (CUT) in partnership with the University of the Free State (UFS) launched a newly published book: Health Ethics for Healthcare Practitioners that aims to raise awareness among healthcare practitioners and patients about various unethical challenges faced by healthcare services in both the private and public sectors.

Prof Laetus Lategan, Director of Research Development and Postgraduate Studies at CUT, and Prof Gert van Zyl, Dean of the UFS Faculty of Health Sciences, are the co-editors of the book intended to provide a moral guide to healthcare professionals when dealing with their patients. 

Holistic approach to healthcare practice

Their work places renewed emphasis on the importance of healthcare ethics. This is due to a diversifying range of healthcare services and the imminent collapse of the public healthcare service sector; most notably in developing countries. The authors particularly focus on how their findings can be integrated into real-life situations.  

The book looks at modern-day healthcare ethics and how they apply to both patients and healthcare practitioners including doctors, professional nurses and therapists. It is an elaborate reference book that will help healthcare practitioners to make informed decisions should they be faced with ethical dilemmas in their practices and assist them to gain a better understanding and devise solutions to problems faced by communities.

Academic journey and partnerships forged
Prof Van Zyl said the book had been a joyful journey of collaboration between the two universities, a journey of academic colleagues who become friends. He explained that they wanted to focus on creating new approaches to healthcare from an ethical perspective, to provide a guide and reference on ethics, not only to healthcare practitioners, but also to patients. “We hope this book will make a difference in healthcare delivery,” he concluded.

Prof Lategan said modern science needed to become more interdisciplinary, which would transcend the way science was conceived. “The essence of healthcare is to be of service to other people and have relationships with other people. I think it’s high time for us to start caring for one another, especially in the academic environment. If we are really looking after the health of other people, whether it is mental, spiritual or physical health, it starts with caring for other people.”
