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.

Dr Truidie Venter, a young scientist from Inorganic Chemistry in the Department of Chemistry at the University of the Free State (UFS), returned recently from presenting a lecture at the 7th World Science Forum, held in Budapest, Hungary. She was one of the few young researchers world-wide who were invited to attend the forum.

In her capacity as a young female researcher from Africa, Truidie was invited by UNESCO to present her views on science in diplomacy at this event. Her talk focused on collaboration between researchers from different countries, and the challenges faced by young researchers in Africa, and served to initiate discussions between young researchers concerning international, interdisciplinary scientific cooperation.

The Science Forum, an international conference dedicated to science and knowledge, was held in Budapest from 4-7 November 2015. This interdisciplinary gathering is supported by the United Nations Educational, Scientific and Cultural Organization (UNESCO), the International Council for Science (ICSU), and other partners, and is aimed at providing an occasion for representatives of science, politics, international organisations, industrial and financial decision makers, international science forums, and science academies to meet and exchange views.

More than nine hundred delegates from 108 countries took part in this event. The speakers included Her Royal Majesty Princess Sumaya Bint El Hassan, President of the Royal Scientific Society of Jordan, Dr Irina Bokova, the Director-General of UNESCO, Prof Sir Peter Gluckman, first Chief Science Advisor to the Prime Minister of New Zealand, Prof Ene Ergma, former President of the Riigikogu (Estonian Parliament), and Ms Naledi Pandor, Minister of Science and Technology of South Africa.

At the conclusion of the forum, a declaration was accepted regarding the renewal of the scientific community’s commitment to the responsible and ethical use of scientific knowledge in addressing the grand challenges of humankind. This declaration addressed the headings of climate change, new sustainable development paths, disaster risk reduction, scientific advice for policies, international collaboration for capacity-building and mobilisation in the developing world, and balanced investment in science.
