Kovsies weld their way to a sustainable environment

The 2019 group of first-year students can look forward to a fun and adventure-filled first two weeks (28 January–9 February) of varsity life, as a number of projects and activities await them.

Kovsie ACT’s main theme for 2019 revolves around building ‘awareness’. This includes a tree-and-traffic-signs project which entails old T-shirts/material being sewn/crocheted together to make different patterns to be fitted around the trees on campus in order to create a beautiful piece of art portraying a message of ‘awareness’.

A canvas painting will also form part of the events, as first-years – with the help of their seniors – will be required to put together a painting that addresses environmental, crime, gender-based, and other societal issues that will later be placed on the wall at the Thakaneng Bridge.

On the morning of 9 February 2019, seniors will tackle the community-engagement leg of the Kovsie ACT line-up, working in their respective teams to decorate an eco-vehicle from waste materials. Each team has their own Pit stop – decorated in F1 style. This eco-vehicle race will take place on Saturday morning from 09:00 – 12:00 in Academia road (in front of Emily Hobhouse Residence).  In addition, art sculptures will be built to form part of the Eco-vehicle race. These art pieces - if approved – will after the Eco-vehicle challenge be assigned a spot on campus where it can spread the message of awareness and be appreciated by fellow students.

The abovementioned projects are expected to withstand adverse weather conditions and last for a minimum of six months.

To close off the Kovsie ACT activities, students and the public can see forward to exciting performances during the Kovsie ACT music festival on the evening of 9 February. This will include musical sensations such as the likes of Sho Madjozi, Bittereinder, Busiswa, and many more.

Tickets for the festival are available at the UFS Bloemfontein Campus Rag Farm and the Food Zone store. For more information on Kovsie ACT, visit https://www.ufs.ac.za/rag or contact Esmé Wessels at WesselsE@ufs.ac.za

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.”
