UFS urges COP26 to make bold decisions on how to reduce greenhouse gas emissions

31 October 2021 | Story Prof Francis Petersen

The University of the Free State (UFS) calls on all higher education institutions, business, the private and public sector, and the South African community to confirm their commitment towards climate change and to contribute to climate change interventions.

“The UFS is committed to contributing meaningfully through research, innovation, policy advice, activism, and the operational management of the university to a fairer, cleaner, and healthier world, and urges world leaders to make bold decisions on how to reduce greenhouse gas emissions at the upcoming Climate Change Conference of the Parties (COP26) meeting in Glasgow,” says Prof Francis Petersen, Rector and Vice-Chancellor.

The UFS supports the United Nations’ (UN) Sustainable Development Goals (SDGs), and in particular Goal 13, which calls for urgent action to combat climate change and its impact and is committed to underpinning it in the institution’s strategy and operations.

According to Prof Petersen, the university is developing a response to positively impact society and is using the SDGs as basis for this response. “This will incorporate our operations in terms of green and sustainable campuses, as well as the Academic Project in terms of quality research, engaged scholarship, and strategic partnerships with government, communities, and different sectors of the economy. A response to the SDGs is a significant step towards our commitment to play a role in climate change,” says Prof Petersen.

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.”
