Rynardt and Lynique selected for SA team at World Cup
Long jumper Lynique Beneke is one of two Kovsies selected for the South African team to the inaugural Athletics World Cup.

University of the Free State (UFS) middle-distance runner, Rynardt van Rensburg, and long jumper, Lynique Beneke, have both secured a spot in the South African athletics team for the inaugural edition of the Athletics World Cup to be held in London, United Kingdom, on 14 and 15 July 2018. 

The 2018 domestic rankings were used to select the team, with one UFS athlete in each discipline set to represent the country as one of the eight competing nations at the event. Beneke, aged 27, won the long jump for women over the past two years at the national track and field championships, this year with a winning distance of 6,22 m. Van Rensburg, aged 26, won silver.

South Africa will compete against teams from the United States, Poland, China, Germany, France, Jamaica, Great Britain, and Northern Ireland. Beneke and Van Rensburg are both experienced athletes who have competed in the Olympic Games in 2016. The programme for the two-day championship does not include long-distance or combined event disciplines. Yolandi Stander, Van Rensburg, and Beneke have also been selected as part of the preliminary team for the CAA African Championships taking place in Asaba, Nigeria from 1 to 5 August 2018.

Van Rensburg recently clocked his personal best, which was also recorded as the 24th best time of the year, when he finished the Hengelo World Challenge meeting in 1:45.15.
Stander, who has a personal best of 52,81 m, won the bronze medal at this year’s nationals and a silver at the University Sports South Africa (USSA) meeting.

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.”
