Are you the next 3MT South Africa winner?

15 July 2021 | Story Lunga Luthuli

The Three-Minute Thesis Competition, also known as the ‘3MT’, is an annual competition held at 200 universities around the world. It is open to PhD and master’s students, challenging participants to present their research in just 180 seconds – in a way that is understood by an audience with no background in the research area.

The competition originated at the University of Queensland, Australia. The UFS Postgraduate School was the first to bring the ‘Three-Minute Thesis’ (3MT) competition to Africa, and it has now become an annual event at the UFS.

The competition aims to assist participants in the development of presentation, research, and academic communication skills, as well as to support the development of research students.

Each faculty will run the 3MT at faculty level. Winners from each faculty will compete against each other during the institutional competition on 1 October 2021 and will stand a chance to win these awesome cash prizes.

UFS INSTITUTIONAL PRIZES FOR 2021 ARE:

Position	Prizes 2021
Master’s winner	R6 000
Master’s 1^st runner-up	R4 000
Master’s 2^nd runner-up	R2 000
PhD winner	R8 000
PhD 1^st runner-up	R6 000
PhD 2^nd runner-up	R4 000

Winners of the institutional competition will go ahead to compete against other universities on 29 October 2021.

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.”
