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.

Fourth Reconciliation Lecture: Audio

McGivern: speech (pdf)

The UFS Annual Reconciliation Lecture brings leaders, scholars, and the broader community together in a shared vision for social change and conflict transformation. This event is organised by Prof Pumla Gobodo-Madikizela, Senior Research Professor in Trauma, Forgiveness and Reconciliation Studies. In 2012, Nadine Gordimer, Nobel Prize Laureate for Literature, was the first speaker to deliver the lecture. This year, at the Fourth Annual Reconciliation Lecture held on the Bloemfontein Campus, Colm McGivern, Director of the British Council in South Africa, continued the legacy.

Doing what must be done
'I get down on my knees and do what must be done
And kiss Achilles' hand, the killer of my son.'
(Ceasefire by Michael Longley)

Using this poem to powerful effect, McGivern showed what reconciliation asks of each and every citizen: to do what must be done. “I think that peace and reconciliation are mutually dependent,” he said. “You can’t maintain one over the long run without attending to the other.”

South Africa’s history has tracked along a similar path to that of Northern Ireland. “And lessons from other places can be powerful and instructive,” McGivern said. Sometimes reconciliation needs a focal point for people to clearly see its power, as Madiba has for South Africa. But at other times, reconciliation needs everyday citizens to “kiss Achilles’ hand’”.

McGivern mentioned Candice Mama and her family, who  have recently forgiven Eugene de Kock,. Or as Gordon Wilson did after his daughter, Mary, died holding his hand in the 1987 Enniskillen bombing in Ireland. In a TV interview mere hours later, Wilson forgave the killers of his daughter, and  hope rippled across Ireland.

Learning from others
“People’s capability,” McGivern said, “to reconcile their own differences, however stark, can be boosted by learning from others in other places, internationally or perhaps just beyond their own identity group.” A powerful truth now being pursued in a joined initiative between the British Council and Teaching Divided Histories.

As an example, McGivern referred to the short film, ‘In Peace Apart’ where one Catholic and one Protestant girl decide to swop school uniforms. Harnessing the potential of moving images and digital media, the initiative enables teachers to explore contentious issues of history and identity in the classroom. This international field of conflict education draws lessons “from activities in Sierra Leone, India, Lebanon, and, of course, South Africa.”

Resuscitation of the national spirit of magnanimity
Here in South Africa, Archbishop Desmund Tutu has “called for a resuscitation of the national spirit of magnanimity and common purpose”, McGivern quoted. In the book, 80 Moments that Shaped the World, South Africa appears four times, McGivern pointed out. And as Archbishop Tutu wrote in the foreword of the book, “no act is unforgivable; no person or country is beyond redemption and the world needs more people to reach out to one another.”
