Can Wayde van Niekerk repeat his amazing feat from the 2016 Olympics – now five years later – at the next Games?

It is a year later, but the Tokyo 2020 Olympics finally started on Friday, 23 July 2021. In team South Africa, a couple of the athletes and management, many of them medal contenders, call themselves Kovsies.

From 1 August, the progress of the country’s golden boy, Wayde van Niekerk, will be closely followed when he tries to hold on to the title as Olympic 400 m champion – he is still the world record holder (set at the 2016 Games). The final of the 400 m is scheduled for 5 August.

One of only five female athletes in the South African team, Gerda Steyn will compete in the marathon on 7 August. This is her first time at the Olympics. 

She is in red-hot form. In April, she broke a 25-year record in Italy when she ran the fastest-ever marathon by a South African woman, finishing in 2:25:28. She is the defending Comrades and Two Oceans champ.

Protea hockey player, Nicole Erasmus, will become a fourth-generation Olympic contender in her family. Her mother, Lynne Walraven (née Tasker) was a Zimbabwean swimmer, her great-uncle, Anthony Tasker, was a member of the South African rowing team, and her great-great-uncle, Frank Rushton, was a South African hurdles athlete. 

From 26 to 28 July, the South African sevens rugby team, with former Shimlas Chris Dry as a team member and Neil Powell as head coach, will aim to improve on their bronze medal achieved in 2016. Powell was also the head coach at the time, and another former Kovsie, Philip Snyman, captained the Blitzboks.

Kate Murray (formerly Roberts), head coach and high-performance manager of Triathlon South Africa, will act as the SA triathlon coach. She is a double Olympic participant, having raced for South Africa at the 2008 and 2012 Olympic Games.

Fire as a management tool questionable in arid and semi-arid grassland areas

The influence of fire on the ecosystem in the higher rainfall ‘‘sour’’ grassland areas of southern Africa has been well established. However, less information is available for arid and semi-arid ‘‘sweet’’ grassland areas, says Prof Hennie Snyman, Professor in the Department of Animal, Wildlife, and Grassland Sciences, about his research on the short-term impact of fire on the productivity of grasslands in semi-arid areas.

Sour and sweet grassland areas can be defined as receiving either higher or lower than approximately 600 mm of rainfall respectively. In quantifying the short-term impact of fire on the productivity of grasslands in semi-arid areas, a South African case study (experimental plot data) was investigated.

“Burned grassland can take at least two full growing seasons to recover in terms of above- and below-ground plant production and of water-use efficiency (WUE). The initial advantage in quality (crude protein) accompanying fire does not neutralise the reduction in half of the above-ground production and poor WUE occurring in the first season following the fire.

“The below-ground growth is more sensitive to burning than above-ground growth. Seasonal above-ground production loss to fire, which is a function of the amount and distribution of rainfall, can vary between 238 and 444 kg ha -1 for semi-arid grasslands. The importance of correct timing in the utilisation of burned semi-arid grassland, with respect to sustained high production, cannot be overemphasised,” said Prof Snyman.

In arid and semi-arid grassland areas, fire as a management tool is questionable if there is no specific purpose for it, as it can increase ecological and financial risk management in the short term.

Prof Snyman said: “More research is needed to quantify the impact of runaway fires on both productivity and soil properties, in terms of different seasonal climatic variations. The information to date may already serve as valuable guidelines regarding grassland productivity losses in semi-arid areas. These results can also provide a guideline in claims arising from unforeseen fires, in which thousands of rands can be involved, and which are often based on unscientific evidence.”
