Schae-Lee Olckers’
UFS PhD student and food scientist Schae-Lee Olckers’ research could contribute to a stable supply of good quality wheat and bread, even in the face of climate change.

Follow your passion in order to find your purpose. This is the mantra of food scientist and University of the Free State (UFS) PhD student Schae-Lee Olckers, whose research is set to improve wheat quality by identifying which types of wheat are better able to tolerate stress, and which proteins are most important for producing high-quality bread. 
 
“By grasping this, it is possible to ensure that we continue to have a stable supply of good quality wheat and bread, even in the face of climate change,” says Olckers, who believes wheat is one of the most important food grains in the human diet, and one of the most important staple cereal crops in the world.

Her PhD study, ‘The influence of abiotic stress on gluten protein and baking quality in bread wheat’, under the supervision of Dr Angie van Biljon and Prof Maryke Labuschagne in the Department of Plant Sciences, and Prof Garry Osthoff in the Department of Microbiology and Biochemistry, is investigating how different levels of heat and drought stress – mostly due to climate change – affect the gluten protein composition of high-yield bread wheat.

Olckers is a food scientist at StartWell Foods (Pty) Ltd, a non-profit organisation that produces high-quality extrusion products for feeding schemes around the country. The products help to eliminate stunted growth among children.

Her research focuses on examining different types of wheat and investigating how proteins are affected by stressors like heat and drought, to understand how these stressors impact the quality of bread. She uses new proteomic methods to look at the different proteins in the wheat flour, to gain a better appreciation of how gluten proteins react to stress.

In this study Olckers is able to see how the proteins change in the various wheat cultivars, helping us to understand how the different types of wheat perform in baking, and how the proteins affect the final product.

She collaborates with the International Maize and Wheat Improvement Center (CIMMYT) in Mexico, that releases new wheat cultivars for developing countries. Their aim is to develop wheat cultivars that maintain their quality in different environments.  To investigate the performance and characteristics of the seeds, both in the field and in the laboratory, CIMMYT did the field trials, quality assessment, and supplied the seeds for high-performance liquid chromatography (HPLC) and proteomics analysis. 

Finding ways to adapt to climate change

She believes that understanding how these stressors impact the production of bread-baking quality in wheat will help scientists gain important insights into how climate change affects our food supply. 

“Taking into consideration the current and projected intensifying heat and water deficit stresses, it is crucial to improve the understanding of these phenomena in order to implement new breeding strategies for sustainable wheat quality. This research could help us find ways to adapt to climate change and continue to produce high-quality wheat and bread for people around the world,” Olckers says.

Important message to UFS students on NSFAS and financial aid in general
2013-02-01

31 January 2013

Dear Students

There remains some uncertainty as well as misinformation within the student body concerning NSFAS and financial aid in general. This communication is intended to provide the facts on the state of student funding at the University of the Free State (UFS). I hope you find this information helpful and that it would guide you in your decisions as you wait to hear from, or hopefully receive funding from NSFAS or any other source.

  1. Every year the Department of Higher Education and Training (DHET) determines how much funding is available to fund students at all universities in South Africa; this is determined in part by the student numbers. Universities do not ask for, or determine the DHET allocation and are instructed by government that “NSFAS will ensure that the universities comply with the processes, procedures…for the allocated funds.”

  2. On 14 December 2012 the UFS received notice from the DHET that our total allocation would be R108,331,215.66 and that this amount must be apportioned in the following categories:
    General NSFAS Funding R85,174,275.07
    Teacher Training R2,291,940.59
    Disability Funding R1,265,000.00
    Final-Year Programme R19,600,000.00

  3. The UFS received 5 952 applications for NSFAS funding and with the available funding we can only finance up to 3 000 students on the Qwaqwa and Bloemfontein Campuses, provided that those students satisfy the stringent criteria, e.g. the so-called “national means test” determined for all universities in the country. If we funded more students that the available monies allow, the university would be held accountable by the NSFAS Board and the DHET and this would threaten future funding.

  4. Students apply in the previous year and therefore late applications are less likely to receive funding.

  5. Academic merit also counts, therefore students who fail one or more modules are less likely to receive new or ongoing support from NSFAS. The combination of academic standing and financial need are among the important criteria in decision-making on NSFAS funds.

  6. The UFS is one of the few universities with a very efficient record in using every cent made available to support poor students; we are proud of this record. No money is sent back to NSFAS, except small amounts not claimed by students in the disability category. The university is not allowed to shift funds between categories as described in point #2 above.

  7. Allocations are not based on campus, but need.

  8. The UFS sets aside an additional R35,7 million (in 2013) from within its own budget as bursaries so that we can accommodate as many students as possible. We spend every cent of this funding on students.

  9. The UFS also raises millions in bursaries from the private sector to support poor and promising students, though these funds are often linked to the industry granting the money, e.g. Investec for Accounting students and SASOL for Chemistry students. This recruitment of bursaries is a 24/7 commitment of the Marketing Office and the Faculties and Heads of Departments are also active in raising funds from government agencies, parastatals and the private sector for students in their units.

  10. After almost all our 2013 funds were allocated in favour of students, we calculated a shortfall in the NSFAS allocation of approximately R51 million. We are in the process of making an urgent submission to NSFAS to consider this additional allocation, but we cannot guarantee that this plea can or will be met.

Finally, I want all our students to know that the University of the Free State works very hard to raise every cent we can to provide poor students with funding for their studies. Many of my colleagues, including support staff, who do not earn very much, use some of their meagre personal resources to help a student with money for registration or clothing or food. In fact, the No Student Hungry Campaign that raises more than R600,000 by UFS volunteers annually, is another mechanism for trying to assist students who might have money for studies, but not much else.

We do this because we care, and because this is what The Human Project at Kovsies is all about.

I therefore ask for your patience as we continue our labour of raising the funds that enable every deserving student to continue their studies at the University of the Free State.

Should you have any further questions about NSFAS, please leave an email inquiry on choanet@ufs.ac.za or mallettca@ufs.ac.za and we will endeavour to provide you with the information you require.

Sincerely Yours

Vice-Chancellor and Rector
