Tharina van der Walt
The hammer thrower Tharina van der Walt is one of several first-class athletes among the first-year students at Kovsies this year. She is the South African U18 champ and record-holder in 2018.

Several top athletes, some of whom were the very best in the country in their respective events at school, have joined Kovsies as first-year students. They already had their first taste of glory as Kovsies when they recently won their events at the first-year meeting.
 
Among these first-years are Jannes Schlebusch (javelin thrower), Joviale Mbisha (sprinter), Colette Uys (discus/shot-put), and Tharina van der Walt (hammer thrower), who have all represented South Africa in the past two years.
 
Schlebusch won the silver medal at the World U18 championships in 2017, but was injured last year. Great things were expected for 2019, but during the first-year meeting he injured his ankle to such an extent that he will have to undergo an operation that would put him on the sideline for the rest of the season.
 
Van der Walt was the South African schools champ in the hammer throw for girls U19 in 2018, when she managed to set up a new school record of 57,83 m. She was ranked fourth at the World U18 champs in 2017. At the same meeting, Mbisha ended 14th in the 100 m.
 
Uys, who participated in the CAA Southern Region Youth and Junior Championships last year, achieved a second place in the discus at the 2018 National Secondary Schools Championships for girls U19. Other first-years who took part in the SA’s last year, are Vicky Oelofse (1 500 m) and Michael Skosana (long jump).
 
They will strengthen Kovsie Athletics, which already boasts a large group of athletes with international experience. Of the 16 athletes who participated internationally last year, only Kesa Molotsane and Lara Orrock will not be in action for the students again.
 
■ Imperium Residence won the men’s division and Arista/Amelia were the ladies’ winners.

Using sugar to make the world a sweeter place

Besides it mainly being used for sugar production, sugarcane has emerged as an important alternative for providing clean renewable energy. Dr Deepack Santchurn, who works in the sugarcane breeding department of the Mauritius Sugar Industry Research Institute (MSIRI), believes if he could contribute towards a more environment-friendly and renewable energy through the use of sugarcane biomass, he would consider himself having made a great leap towards a better world. 

Sugarcane is mostly known and exploited for the sugar in its cane stem. According to Dr Santchurn it is not the only thing the crop does well. “Together with certain grasses, it is the finest living collector of sunlight energy and a producer of biomass in unit time. Sugarcane is now recognised worldwide as a potential renewable and environment-friendly bioenergy crop.” 

Significantly more bioenergy can be produced from sugarcane if the production system is not focused on the production and recovery of sucrose alone but on the maximum use to the total above-ground biomass. Diversification within the sugarcane industry is of paramount importance. 

He has been able to identify a few high biomass varieties that can be exploited industrially. One of the varieties is a commercial type with relatively high sugar and low fibre in the cane stem. Dr Santchurn explains: “Its sucrose content is about 0.5% less than the most cultivated commercial variety in Mauritius. Nevertheless, its sugar yield and above-ground biomass yield surpass those of the commercial varieties by more than 24%. The genetic gains compared to commercial varieties were around +50% for total biomass yield and +100% for fibre yield. Its cultivation is strictly related to bio-energy production and the extracted juice can be used as a feed-stock for ethanol and other high-value products.”

Dr Santchurn received his PhD at the UFS’s Department of Plant Sciences during the Winter Graduation Ceremonies in June this year. His study leader was Prof Maryke Labuschagne from the Department of Plant Sciences.
