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.

"Participation without insight leads to pronouncements without prospects"
2004-08-30

Taking the poor off the streets and encouraging their participation in the planning process is not always empowering them but it might be robbing them of their power, said Prof Das Steyn, of the Department of Urban and Regional Planning at the University of the Free State (UFS).

Speaking on public participation in the planning process during his inaugural lecture, Prof Steyn said this meant that people in the streets sometimes have more power than people in the system.

“Public participation is an overgeneralization that is often defined as providing citizens with opportunities to take part in governmental decisions and planning processes. But there must be a balance between power and responsibility,” he said.

According to Prof. Steyn, public participation in town planning plays a vital role and can be both deliberation and participation.

After 1994 there was a widespread insistence on democracy, and legislation passed since then was based on the belief that the community must be involved in the planning process.

He said the experience of the Department of Urban and Regional Planning at the UFS was that in some cases people showed lack of interest in public participation.

He believed that the aim of public participation is to improve the effectiveness of planning and that public participation democratises project planning.

“Public participation can help us know how the public feels about certain issues. It has the potential of resolving a conflict, but this is not guaranteed,” Prof Steyn said.
