Research-industry linkages for the promotion of biofortified maize and wheat, highlighted the link between research and industry.

Prof Maryke Labuschagne believes that research through collaboration can be to the benefit of the whole food chain, literally from laboratory to farm to fork. 

She is professor of Plant Sciences at the University of the Free State (UFS) and heads the SARChI Chair: Disease Resistance and Quality in Field Crops.

Prof Labuschagne recently delivered a presentation at a webinar organised by the International Maize and Wheat Improvement Center (CIMMYT) and the United States Agency for International Development (USAID). The focus was on Maize: Technologies, Development and Availability in South Asia. 

Her presentation: Research-industry linkages for the promotion of biofortified maize and wheat, highlighted the link between research and industry, stating that research outcomes should improve the livelihoods and health of people who grow and consume the food. 

Prof Labuschagne believes research by universities and research organisations can be linked to industry, with special reference to the development of biofortified crops. “Biofortification is the process where crop nutritional value is improved through genetic intervention,” she explains.

She states that the same technologies for crop biofortification can be applied throughout the world. 

In her presentation, Prof Labuschagne also reviewed the current technologies used, which include conventional genetic improvement and genetic engineering. Recently, the latter has been increasingly used for crop biofortification.

Enhancing nutritional value of crops

According to Prof Labuschagne, crop biofortification has developed exponentially in the last decade. Crop biofortification has been very successful in terms of improving the iron and zinc content, the provitamin A content, and the amounts of essential amino acids (lysine and tryptophan) in various staple foods.

“What we have learned is that genetic intervention in crop nutritional value is the best long-term solution to sustainably address vitamin and micronutrient deficiencies, especially in poor communities. It is a sustainable, and relatively cheap way to address mineral and vitamin deficiencies in the diets of people,” she says.

UFS research on biofortification

For a number of years now, a team of UFS scientists in the Division of Plant Breeding has been doing research on the biofortification of maize, sweet potatoes, bananas, and cassava. “The research took place in collaboration with a number of partners in Africa, and with funding from organisations such as the Bill and Melinda Gates Foundation.”

“This research has resulted in tangible outcomes, including the availability of seed and planting material of biofortified crops for farmers, who in turn make these crops available to consumers,” says Prof Labuschagne.

The crops not only add to the well-being of consumers, especially children and women, but also contribute to food security.

Harvard couple to present lectures on Biostatistics and Mathematics at the UFS
2015-12-07


Professor Donald Rubin

Prof Donald Rubin (John L. Loeb Professor of Statistics at Harvard University) and Elizabeth Zell (MStat - mathematical statistician in the Division of Bacterial Diseases) will visit the University of the Free State (UFS) where they will present lectures on their respective work.

Over his prestigious academic career, Prof Don Rubin’s 400 publications and 13 books have earned him around 180 000 citations at an h-index of 113. He is one of the most cited statisticians/mathematicians/economists/psychologists in the world over the last 10 -15 years. He has supervised 35 PhD candidates as sole-supervisor, 17 more as co-supervisor, with a further eight in the pipeline.

Prof Rubin who will meet with UFS academics in the Department of Mathematics and Actuarial Sciences will also deliver a lecture: Rerandomisation to improve covariate balance in experiments.

Randomised experiments are the “gold standard” for estimating causal effects, yet in practice, chance imbalances often exist in covariate distributions between treatment groups. If covariate data are available before units are exposed to treatments, these chance imbalances can be mitigated by first checking covariate balance before the physical experiment takes place. Provided a precise definition of imbalance has been specified in advance, unbalanced randomisations can be discarded, followed by a rerandomisation. This process can continue until a randomisation yielding balance according to the definition is achieved. By improving covariate balance, rerandomisation provides more precise and trustworthy estimates of treatment effects.

Prof Rubin received an honorary professorship from the Faculty of Natural and Agricultural Sciences at the UFS.


Elizabeth Zell

The lecture will take place on:
Date: Tuesday 8 December 2015
Time: 16:00
Venue: Albert Wessels Auditorium, Bloemfontein Campus

Zell earned her Master’s degree in Statistics at North Carolina State University, and for more than two decades, was an active bio-statistical researcher in various offices of the Centers for Disease Control (CDC). Since 2013, she has been the Principal Statistician and President of Stat-Epi Associates, Inc. Her 150+ publications have earned her 14 500 citations at an h-index of over 50. She is a Fellow of the American Statistical Association, and, in 2010, she received the Statistics Section Government Award for outstanding contributions to statistics and public health by the American Public Health Association. During her career at the CDC, she earned more than 20 CDC research awards and honours.

She will deliver two lectures at the UFS. The first is entitled A Potential Outcomes Approach to Documenting the Public Health Impact of the Introduction of PCV13 for the Prevention of Invasive Pneumococcal Disease. The topic of her second lecture is: Assessing the Effectiveness of Intrapartum Antibiotic Prophylaxis for Prevention of Early-Onset Group B Streptococcus Disease through Propensity Score Design

Elizabeth’s lectures will take place on:
Date: Wednesday 9 December 2015
Time: 10:45 and 13:00
Venue: West Block 111, Bloemfontein Campus
