Christina Mack – believes in praying for communities.

Leaving Rustenburg in the North-West for the Free State, Christina Mack’s life has changed for the better. Mack, a Housekeeping Manager on the University of the Free State (UFS) Bloemfontein Campus, believes in hard work and honesty – these are the principles she has lived by for many years. 

“I was fortunate to get a job as a cleaner at the university in 2006, a position I held until I was promoted to Housekeeping Manager in 2016.

“I believe in myself; I am a hard worker and because I am a manager, I always strive for honesty. When I have a challenging day – especially at work, I engage with colleagues with honesty.”

One of the many UFS women of quality, impact, and care, Mack says she is living the life she imagined through some powerful life lessons.  

“I have learnt that in life, you must appreciate everything that is good, have a vision, focus on education, and know your position. You must not only pray for yourself, but also for your community.”

Women who inspire her include her Line Manager, Ronell Kruger. “She encourages and supports me, and she is a hardworking woman. Ronell motivates her staff. In the team, she is a mentor and supports all of us.”

What worries her is the continued and high number of gender-based violence cases across the country. “Government should create platforms for men to be taught about taking care of women. Women deserve equal rights to their male counterparts.”

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.”
