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.

Community Engagement Indaba a platform to engage Free State community stakeholders
2016-12-14

Description: Community Engagement Indaba Tags: Community Engagement Indaba  

Teaching women handicrafts for self-sustainability.

The University of the Free State (UFS), through the office of Community Engagement and in collaboration with Bloemshelter, has hosted the Community Engagement Indaba in Bloemfontein since 2013. This is a platform where stakeholders in business, welfare and other community organisations can network and hold dialogues that can bring about solutions to some of the societal challenges faced by Free State communities.

Bloemshelter is an independent and registered Non-Profit Organisation (NPO) and Public Benefit Organisation that provides shelter for the homeless; catering for women, women with children, the elderly, men and frail persons. The shelter accommodates up to 100 people in both the male and female shelters. The growing partnership it has with the UFS over recent years has grown its ability to reach out to local communities in a more effective way.

At the 2016 Community Engagement Indaba on 25-27 August, a number of stakeholders were invited to participate in the skills development action-learning workshops, under the theme: Unlocking Human Potential and Creating Jobs. This was a platform to strengthen the university’s partnerships with NPOs and other advocacy groups in the province. UFS academics, Community Service Learning students and community partners gave their presentations while the Director of Community Engagement, Bishop Billyboy Ramahlele, offered carpentry training. Among the participating collaborators was the Free State Department of Education, Celebrate Recovery, ABSA Bank, The Shunammite Foundation, Lebone Village, and Global University of Lifelong Learning (GULL).

Those who attended received certificates that will in future help them build a portfolio of learning evidence. The conference was about creating meaning, igniting learning, propelling movement, inspiring hope and encouraging sharing by bringing together students, academics and members of communities. The next Community Engagement Indaba will be held next year, on a date that will be announced early in the year.
