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.

Rag spreads the spirit of Ubuntu in Dinaweng informal settlement
2015-08-25

 

The Rag Committee teamed up with Prowess to create the first pop-up Street Store in Bloemfontein, as part of the Ubuntu Community Store Project. On 22 August 2015, the residents of Dinaweng had the opportunity to get hold of new and second-hand clothing free of charge. Soup and bread were also served to the children and the elders of the area, which is all too familiar to the media for its high unemployment, crime, and prostitution rates.

How do clothes represent Ubuntu?

From Tubatsi Moloi’s perspective, this is the team’s way of demonstrating that Ubuntu does not exist merely as a philosophy. The Rag Committee shows compassion to communities that lack resources essential to leading a dignified life.

“Ubuntu basically means uniting with the community by giving back and also thinking for those who are in need,” says the RAG Committee Executive.

Prowess, a Non-Profit Organisation (NPO) run by Kovsie students, initiated the concept which targets homeless and needy individuals unable to purchase clothing. Students from all 26 Kovsie residences and personnel have since supported the initiative by donating to the inaugural Street Store through representatives of Rag in residences.

The Street Store will continue to empower impoverished communities within the Mangaung Metro, and champion these human projects in collaboration with external stakeholders.
“We will also be working with Twee-Toring Church, although it has not yet been confirmed when we will pay them a visit,” said Tubatsi.

Providing basic needs such as clothing has the power to reinstate the dignity of people. Rag and Prowess have taken it upon themselves to practice the ideals of Ubuntu in an attempt to ensure that the less fortunate lead dignified lives.
