Prince Matova, a PhD student in the Department of Plant Sciences, has been working on breeding a maize that can resist the fall armyworm (FAW) – a maize-eating pest. Later in September, he will receive the Young Scientist Award from the Plant Mutation Breeding Division of the International Atomic Energy Agency (IAEA) and the Food and Agriculture Organisation of the United Nations (FAO).

Prince Matova, a PhD student in Plant Breeding at the University of the Free State (UFS), received the Young Scientist Award from the Joint Food and Agriculture Organisation of the United Nations (FAO)/International Atomic Energy Agency (IAEA) Division of Nuclear Techniques in Food and Agriculture for excellence in plant mutation breeding.

The IAEA Director-General, Mr Rafael Mariano Grossi, will officially announce the award at the 65th regular session of the IAEA General Conference that will take place later in September this year.

The award is given to scientists younger than 40, who have made a significant contribution and impact in the field of mutation breeding.

Matova, a researcher, research and agronomy manager, and maize and legumes breeder at Mukushi Seeds (Pvt) Ltd in Harare, Zimbabwe, says: “People have seen the little work that I have done, and they were happy with it. That makes me happy too.”

Other contributions

In the ten years collaborating with the IAEA, practising mutation breeding, Matova – who believes innovative thinking and self-motivation to be contributing factors to a successful scientist – has also been recognised for other outstanding contributions. These include the release of a cowpea mutant variety in 2017 and its wide dissemination across Zimbabwe, as well as the modernisation of the maize and cowpea national breeding programmes. He has also contributed two publications and appeared twice at IAEA Plant Mutation Breeding symposia. Furthermore, Matova has trained other scientists and fellows across Africa and collaborated with centres of excellence in plant breeding, research, and development.

Growing up, he never guessed that he would one day become an agricultural scientist. Matova was, however, very good at biology and believes that this is one of the reasons why he ended up in crop science. “I am enjoying every moment of it. I love innovativeness and inventions and I view hybrid maize variety development as the greatest innovation in plant breeding. Working for Mukushi Seeds is inspiring; I have a young and dedicated team and the environment allows me to explore my full potential.”

“I feel science solves problems and every day as I do my breeding work, I have this desire to achieve greatness by developing a super maize hybrid,” he says.

Displaying excellence

For the past three to four years, Matova has been working to breed maize varieties that can resist fall armyworm (FAW) – a maize-eating pest. He says the pest has caused significant maize crop yield and economic losses across Africa.

More than 300 million smallholder farmers across sub-Saharan Africa rely on maize for food and livelihoods. “These farmers have limited capacities to control the pest. They are using insecticides, which we have seen to effectively provide immediate control of the pest.” However, these pesticides have environmental and health issues. “It is against this background that we, as plant breeders, felt it was important to develop varieties that are resistant to the pest. It is a more environmentally friendly, less expensive, and more sustainable solution,” explains Matova.
In his research, he evaluated the breeding potential of exotic FAW-resistant donor lines with local lines. He also investigated the resistance response and stability of local cultivars and inbred lines against FAW. 

While working at the Zimbabwean Department of Research and Specialist Services (DR&SS), Matova collaborated with the International Maize and Wheat Improvement Center (CIMMYT), the University of Zimbabwe, the UFS, and the IAEA to look into the possibility of using mutation breeding in maize crop improvement, with the intention to enhance FAW-resistance in maize genotypes.

He introgressed FAW resistance into the elite breeding materials at both DR&SS and Mukushi Seeds, where he is currently working. Matova believes that although FAW resistance is currently a nice-to-have trait, going forward, all maize varieties released should have a baseline resistance to FAW.

Ultimately, his work generated important information that can guide research and maize breeding for FAW resistance in Southern Africa. All this information is free for researchers to use for the betterment of Africa and the world.

Inspired by greatness

There are a number of people in the industry and academia who have inspired Matova. The list includes Dr Cosmos Magorokosho (CIMMYT), Prof Hussein Shimelis (University of KwaZulu-Natal), Dr Fatma Sarsu (IAEA), Dr Marilyn Warburton (Agricultural Research Service in the United States Department of Agriculture), Dr Amsal Terekegne (ZAMSEED), and Dr John MacRobert (Mukushi Seeds). They all contributed in one way or another to influence Matova in a positive way towards becoming the passionate scientist he is today.

Besides this list of prominent names, Matova says that he was more recently also motivated and encouraged by his PhD supervisor and mentor, Prof Maryke Labuschagne, Professor in Plant Sciences at the UFS. “She is a very special person doing a wonderful job. Prof Labuschagne is kind, thorough, hardworking, and a good mentor,” he states.

Prof Labuschagne is very proud of Matova for receiving this award. “He has been working really hard, and this is a wonderful recognition of the time and effort that he has invested in his research,” she says.

Fracking in the Karoo has advantages and disadvantages

Fracking for shale gas in the Karoo was laid bare during a public lecture by Dr Danie Vermeulen, Director of the Institute for Groundwater Studies (IGS). He shared facts, figures and research with his audience. No “yes” or “no” vote was cast. The audience was left to decide for itself.

The exploitation of shale gas in the pristine Karoo has probably been one of the most debated issues in South Africa since 2011.
 
Dr Vermeulen’s lecture, “The shale gas story in the Karoo: both sides of the coin”, was the first in a series presented by the Faculty of Natural and Agricultural Science under the theme “Sustainability”. Dr Vermeulen is a trained geo-hydrologist and geologist. He has been involved in fracking in South Africa since the debate started. He went on a study tour to the USA in 2011 to learn more about fracking and he visited the USA to further his investigation in May 2012.
 
Some of the information he shared, includes:

- It is estimated that South Africa has the fifth-largest shale-gas reserves in the world, following on China, the USA, Argentina and Mexico.
- Flow-back water is stored in sealed tanks and not in flow-back dams.
- Fracturing will not contaminate the water in an area, as the drilling of the wells will go far deeper than the groundwater aquifers. Every well has four steel casings – one within the other – with the gaps between them sealed with cement.
- More than a million hydraulic fracturing simulations took place in the USA without compromising fresh groundwater. The surface activities can cause problems because that is where man-made and managerial operations could cause pollution.
- Water use for shale-gas exploration is lower than for other kinds of energy, but the fact that the Karoo is an arid region makes the use of groundwater a sensitive issue. Dr Vermeulen highlighted this aspect as his major concern regarding shale-gas exploration.
- The cost to develop is a quarter of the cost for an oil well in the Gulf of Mexico.
- Dolerite intrusions in the Karoo are an unresearched concern. Dolerite is unique to the South African situation. Dolerite intrusion temperatures exceed 900 °C.

He also addressed the shale-gas footprint, well decommissioning and site reclamation, radio activity in the shale and the low possibility of seismic events.
 
Dr Vermeulen said South Africa is a net importer of energy. About 90% of its power supply is coal-based. For continued economic growth, South Africa needs a stable energy supply. It is also forecast that energy demand in South Africa is growing faster than the average global demand.
 
Unknowns to be addressed in research and exploration are the gas reserves and gas needs of South Africa. Do we have enough water? What will be the visual and social impact? Who must do the exploration?
 
“Only exploration will give us these answers,” Dr Vermeulen said.
