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.

“This rating will motivate me to do more research, to improve outcomes, and to aim for a higher C-rating.” This was the response of Dr Jay le Roux, who was recently graded as an Y2-rated researcher by the National Research Foundation (NRF).

Dr Le Roux, senior lecturer in the Department of Geography at the University of the Free State (UFS), is one of 31 new NRF-rated researchers at the UFS. “This grading will make it possible to focus on more specific research during field research and to come in contact with other experts. Researchers are graded on their potential or contribution in their respective fields,” he said.

Research assess different techniques
His research on water erosion risk in South Africa (SA) is a methodological framework with three hierarchal levels presented. It was done in collaboration with the University of Pretoria (UP), Water Research Commission, Department of Agriculture, Forestry and Fisheries, and recently Rhodes University and the Department of Environmental Affairs. Dr Le Roux was registered for 5 years at UP, while working full-time for the Agricultural Research Council – Institute for Soil, Climate and Water (ARC-ISCW).

Water erosion risk assessment in South Africa: towards a methodological framework
, illustrates the most feasible erosion assessment techniques and input datasets that can be used to map water erosion features in SA. It also emphasises the simplicity required for application at a regional scale, with proper incorporation of the most important erosion-causal factors.

The main feature that distinguishes this approach from previous studies is the fact that this study interprets erosion features as individual sediment sources. Modelling the sediment yield contribution from gully erosion (also known as dongas) with emphasis on connectivity and sediment transport, can be considered as an important step towards the assessment of sediment produce at regional scale. 
 
Dams a pivotal element in river networks

Soil is an important, but limited natural resource in SA. Soil erosion not only involves loss of fertile topsoil and reduction of soil productivity, but is also coupled with serious off-site impacts related to increased mobilisation of sediment and delivery to rivers.

The siltation of dams is a big problem in SA, especially dams that are located in eroded catchment areas. Dr Le Roux recently developed a model to assess sediment yield contribution from gully erosion at a large catchment scale. “The Mzimvubu River Catchment is the only large river network in SA on record without a dam.” The flow and sediment yield in the catchment made it possible to estimate dam life expectancies on between 43 and 55 years for future dams in the area.
 
Future model to assess soil erosion
“I plan to finalise a soil erosion model that will determine the sediment yield of gully erosion on a bigger scale.” It will be useful to determine the lifespan of dams where gully erosion is a big problem. Two of his PhD students are currently working on project proposals to assess soil erosion with the help of remote sensing techniques.
