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.

The International Office and the Department for Community Engagement will host a week-long cultural immersion programme for eight students of Rutgers University from 27 July – 2 August 2014. The Rutgers Graduate School of Education's South Africa Initiative (SAI) bridges cultures, connects educators and provides hope for learners and students from South Africa and the United States.

This interdisciplinary programme provides teachers and students on both sides of the world with the opportunity to exchange information through service learning, training and distance technology. This leads to educational gains for students and educators in both countries.

The Rutgers group of master’s, PhD and undergraduate students will visit two NGOs working with children at risk in the community of Heidedal, namely Tshepo Foundation and Lebone Village. The week-long programme will include lectures on the social, cultural and historical background of pre- and post-apartheid South Africa. Speakers from various departments and faculties of the UFS will feature during this event. These include the Institute for Reconciliation and Social Justice, the Postgraduate School, the Department of History, African Languages, as well as Education.

Prof André Keet, Director of the Institute for Reconciliation and Social Justice, will share the transformation story of our university with the group. Dr Henriette van den Berg will speak on mentoring postgraduate students to become successful researchers of the future.

This year marks the 12th anniversary of the SAI Cultural Immersion Program and a fruitful partnership with the UFS and other South African universities. Over the years SAI has provided tonnes of school books and supplies which have been shared with more than 2 000 learners in South Africa. Special projects such as the Literacy Through Photography and Brielle Digital Stories Project have been conducted by SAI alumni in schools. These have resulted in thousands of dollars of support given directly to South African schools.
