Prof Maryke Labuschagne, a successful scientist who is doing great work to enhance food security on the African continent, admires women who have made an impact, often in male-dominated environments.

Maryke Labuschagne, Professor in Plant Breeding at the University of the Free State (UFS), is known to many for her work to enhance food security. 

She holds the National Research Foundation’s South African Research Chairs Initiative (SARChI) Chair on Disease Resistance and Quality in Field Crops, travelling all over Africa to do research on the genetic improvement of staple food crops in communities. Through decades of research and collaboration, she has also contributed to the establishment of a strong network of researchers on the continent.

During an interview in celebration of Women’s Month, Prof Labuschagne talks about her experiences as a young scientist and how she believes young female researchers should be supported and nurtured. 

Is there a woman who inspires you and who you would like to celebrate this Women’s Month, and why?

Besides the scientists she had the opportunity to work with in countries such as Zimbabwe, Zambia, Uganda, Ghana, Ethiopia, Kenya, Lesotho, Eswatini, Tunisia, and Ethiopia, she also met women who are working the fields to produce crops for their families, raising their children, and living in difficult conditions. “These women, who make it work against all odds, inspire me,” says Prof Labuschagne.

Other women she admires and who have made an impact – often in male-dominated environments – include role models from the past, such as former UK prime minister, Margaret Thatcher; physicist Marie Curie, who was far ahead of her time; and American geneticist Barbara McClintock, who won a Nobel Prize in 1983. 

What is your response to current challenges faced by women and available platforms for women development?
 
“When I started working in the Faculty of Natural and Agricultural Sciences at the UFS in 1989, it was a different world. It was a totally (white) male-dominated environment. The number of women scientists could be counted on the fingers of one hand, and they were often not given the same opportunities as their male counterparts,” she recalls.

Prof Labuschagne continues: “With women having so many opportunities today, it is now totally different.”

She believes women will always have a double burden – being responsible for a family and having to compete on an equal footing with male colleagues in the workplace. There are now, however, many platforms and support systems specifically for women, and she encourages women to make use of every available form of assistance they can get.

I would say you can have it all. Work hard, believe in yourself, follow your dreams, focus on your goals, see the opportunities – not the challenges, and leave a legacy. – Prof Maryke Labuschagne
 
What advice would you give to the 15-year-old you?

“I would say you can have it all. Work hard, believe in yourself, follow your dreams, focus on your goals, see the opportunities – not the challenges, and leave a legacy.”

She is convinced that young women can have a family and a career, even if they believe it is not possible. 
 
What would you say makes women of quality, impact, and care?
 
“I see many women at the UFS making their mark, making an impact in their chosen fields.”

According to Prof Labuschagne, what would have been unthinkable just a few decades ago, such as women serving as deans and in top management positions, is now a reality. 

“I see young female researchers boldly taking on the world, believing in themselves and their abilities, and knowing they will be successful.” She states that each of these women should be supported and nurtured, as they will have a huge influence on the course of the university’s future.

Her advice to farmers is that they should make sure they are aware of the total cost (investment and operating costs) of an irrigation system. In most cases the investment cost is low, but the operating cost over the lifetime of the system is high.

“It is very important to have a look at the total cost and to install the most economic system,” says Marcill Venter, lecturer at the University of the Free State (UFS), who has done research on the economic sustainability of water-pipe systems.

Irrigation systems important components for farming
This research comes at a time when many farmers are relying on their irrigation systems due to persistent drought and low rainfall during 2016. South Africa has also experienced an abnormal increase in electricity tariffs in recent years. Due to tariff increases which threaten the future profitability of irrigation producers, the Water Research Commission (WRC) has launched and financed a project on the sustainable management of irrigation farming systems. “I had the opportunity to work on the project as a researcher,” says Venter.

The heart of every irrigation system is the water pipes that bring life to crops and livestock, and this is what Venter’s research is about. “Water pipes are part of the whole design of irrigation systems. The design of the system impact certain factors which determine the investment and operating costs,” she says.

Mathematical system to help farmers
Venter and Professor Bennie Grové, also from the Department of Agricultural Economics at the UFS, designed the Soil Water Irrigation Planning and Energy Management (SWIP-E) programming model as part of the WRC’s project, as well as for her master’s degree. “The model determines irrigation pump hours through a daily groundwater budget, while also taking into account the time-of-use electricity tariff structure and change in kilowatt requirements arising from the main-line design,” says Venter. The model is a non-linear programming model programmed in General Algebraic Modeling System (GAMS).

Design of irrigation system important for sustainability

The main outcome of the study is that the time-of-use electricity tariff structure (Ruraflex) is always more profitable than the flat-rate structure (Landrate). The interaction between the management and design of a system is crucial, as it determines the investment and operating costs. Irrigation designers should take the investment and operating cost of a system into account during the design process. The standards set by the South African Irrigation Institute (SAII) should also be controlled and revised.

Water-pipe thickness plays major role in cost cuts
There is interaction between water-pipe thickness, investment and operating costs. When thinner water pipes are installed, it increases the friction in the system as well as the kilowatt usage. A high kilowatt increases the operating cost, but the use of thinner water pipes lowers the investment cost. Thicker water pipes therefore lower the friction and the kilowatt requirements, which leads to lower operating costs, but thicker pipes have a higher investment cost. “It is thus crucial to look at the total cost (operating and investment cost) when investing in a new system. Farmers should invest in the system with the lowest total cost,” says Venter.
