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.

UFS serious about safe campuses

The University of the Free State (UFS) officially launched its security control room recently. This new addition to the university's infrastructure, which was implemented in December 2010, has already made a contribution to the combating of crime at the UFS.

The decrease in crime statistics for January this year (5 cases), in comparison to the statistics of January 2010 (51 cases) is proof that the UFS’s new approach to combating crime on campus has an impact.
 
According to Prof. Niel Viljoen, Vice-Rector: Operations, the safety of students, lecturers and staff of the UFS is of the utmost importancet. For this reason, it is continuously reflected on about what can be done to improve the levels of safety for the respective campuses.
 
Apart from the upgraded security control room, from where, amongst others, residences, pedestrian routes, campus buildings, parking areas, entrances at gates and computer rooms at residences are observed, a number of measures have been set in place to improve the task of combating crime.
 
These measures include:
-       Security cameras in front of all the women’s residences. The UFS is in the process of also installing
        security cameras in front of the men’s residences.
-       Shrubs and trees that caused obstruction in front of cameras have been pruned.
-       Security officers patrol the pedestrian routes as well as the Red Square on foot from 06:00-22:00.
-       A security officer has been appointed at each residence to be on duty from 18:00 to 06:00
        at the residence.
-       Two vehicles patrol the Main Campus on a 24-hour basis.
-       The UFS is in die process to install alarms, which will be linked to the central security control room, 
        in all buildings.
-       In certain buildings panic buttons have been installed in strategic places.
-       Where possible, better entrance control to building, especially office blocks, has been implemented.
-       Better management and integration of the security workers who are contracted from outside.
        More security workers have also been appointed to do duty at each residence as well as on the
        pedestrian routes (during the hours indicated).
-       A survey has once again been done of all “dark spots” on the campus and better lighting is 
        currently being installed.
 
The reduced reaction times are a direct result of the operational process between security staff in the control room with met security staff that patrols the campus on foot and by vehicle
