Nearly 150 students from across the world will gather in Egypt for the COP27 Simulation Model from 9 September to mid- October 2022. Among them will be Letsatsi Lekhooa, a Master of Science student specialising in Climate Change from the University of the Free State (UFS). 

Lekhooa was one of 150 students from a pool of more than 1 800 applicants across the world who were selected to be part of this prestigious initiative. “This opportunity is appealing, because as young people we need to work hard to not only ensure that we break through walls, but to also represent our university well everywhere we go,” Lekhooa indicated.

The COP27 Simulation Model

The COP27 Simulation Model, which is organised by the British University in Egypt along with the United Nations Development Programme (UNDP), is a worldwide climate conference led by and targeted at the youth. The conference is important for several reasons, such as encouraging conversations around climate action among the youth. As it stands, the initiative is split into two categories, which include the hybrid capacity-building programme that started in September, and the COP27 Mock Conference set to begin in October. Lekhooa is currently engaged in the online capacity-building programme, which he describes as a learning curve. “Every day I learn something new, and I enjoy it because the process is assisting me in learning more about this climate change issue,” Lekhooa expressed. 

The benefits of attending the COP27 Mock Conference

Although the first leg of the COP27 Simulation Model is online, Lekhooa will get the opportunity to travel to Egypt and physically be part of the COP27 Mock Conference on the campus of the British University in Egypt. As such, he hopes to take away as much as possible from the experience. “I hope to learn about the ways in which I can better communicate this climate change issue, not only in my home country of Lesotho, but generally in Southern Africa,” said Lekhooa. Furthermore, through his interactions with international scholars, he hopes to create and encourage a collaborative spirit to battle climate change. 

The experience does not only serve as a learning curve for Lekhooa, but it is also one of the key steps that will allow him to reach a life goal. “I would like to be an international consultant in bodies such as the Intergovernmental Panel on Climate Change (IPCC), and the United Nations Framework Convention on Climate Change (UNFCCC), as they play a key role in making decisions on climate change,” Lekhooa highlighted.

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.”
