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.

White Horse to bring enchantment to Free State Arts Festival
2015-07-09

White Horse Project: Concept, Jess Oliveiri & Parachutes for Ladies; Project Manager, Mandi Bezuidenhout; Video, Louis Kruger; Costume, Lesiba Mabitsela; Performers, Gali Malebo, Chris Kleynhans, Busisiwe Matutu, Johandi du Plessis, Elrie du Toit.

A University of the Free State (UFS) and Free State Arts Festival initiative, the Programme for Innovation in Artform Development (PIAD/PIKO) has worked together with Australian artist, Jess Olivieri (Parachutes for Ladies), to bring visitors and spectators the fantastical and mythical White Horse. The UFS has served as home for the festival for a number of years, and is pleased to take part in bringing this communal project to the arts community that will gather at the annual festival.

The White Horse project begins Sunday 12 July 2015 at 15:00 at the Tweetoringkerk in Bloemfontein, launching the arts festival, while capturing the interest of many members of the Bloemfontein community as well as that of the UFS. The project itself will consist of about 200 members of the local community coming together for workshops in which they will be “reimagining” the White Horse. Olivieri will lead the workshops, which she also developed, assisted by Gali Malebo.

“The White Horse project sits within the contested nature of the White Horse - it is in this in-between space that new mythologies and narratives will be told. The project addresses, celebrates, reconfigures, and allows space for multiple narratives.  Given the debate on statues and symbols, the White Horse offers an opportunity to re-purpose and re-imagine symbols in Bloemfontein,” said Olivieri.

The White Horse project is supported by the Australia Council for the Arts, Free State Department of Sport, Arts, Culture and Recreation, SituateART in Festivals, Salamanca Arts Centre, Arts NSW, NAVA, Creative Partnerships Australia and the University of Sydney.

Spectators can also look forward to the work of major artists including David Goldblatt’s photographic exhibition titled Structures of Dominion and Democracy at 20:00 on Monday 13 July 2015 at the Johannes Stegmann Art Gallery. In this exhibition, he has photographed everyday sites that contain historical narratives.

Work from other artists at the Arts Festival include Blowing in the Wind (19:00 on Monday 13 July 2015 in the Centenary Gallery), curated by Carol Brown, which is an exhibition that delves into issues of environmental and human exploitation. Angela de Jesus, curator of the UFS Johannes Stegmann Art Gallery, will be curating, [my] PLEK | PLACE (18:30 on Monday 13 July 2015 in the Scaena foyer), in which the artists explore location, space, site, and/or ownership.

The Free State Arts festival begins on 13 July 2015.
