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.

DiMTEC and insurance industry join forces to address the vulnerability of communal and commercial farmers
2015-09-18

At the workshop on index-based insurance for the
agricultural sector were, from the left:

The United Nations identified climate resilience as a major focus for future development to ensure a safer world for all. Tailor-made insurance and financial products ought to address the needs of the most vulnerable.

Recent research done by the Disaster Management Training and Education Centre for Africa (DiMTEC) at the University of the Free State on the vulnerability of communal and commercial farmers to external shocks highlighted the importance of insurance as an important disaster risk transfer tool. Insurance is generally unavailable to most vulnerable groups, such as communal farmers, small-holding farmers, and new commercial farmers.

For these reasons, DiMTEC invited the insurance industry and other experts to a workshop with the purpose of investigating the development of risk transfer products, especially for drought. They were the hosts of a workshop entitled “Global Resilience through Insurance and Index-Based Risk Transfer Products (IBRTP)”.

Bertus Kruger from Agriseker and Johan van der Berg from SANTAM, together with other experts, attended the workshop facilitated by Dr Andries Jordaan, Head of DiMTEC.

The group attending the workshop, agreed on the following:

- Establishing a UFS-DiMTEC-led research team to investigate the feasibility of index insurance products.
- Mobilising government support to develop risk transfer products for the most vulnerable.
- Initiating forum discussions on risk transfer products.
- Promoting collaboration between the private sector, government, and research institutions with the focus on resilience-building through financial and insurance products.
