Prof Geofrey Mukwada from the Department of Geography on the Qwaqwa Campus delivered his inaugural lecture, which focused on elevation-dependent warming in the Drakensberg Mountain region.

South Africa is generally regarded as a thirsty country due to water scarcity nationally. Even a rise of 0,5 °C in climate temperatures could have devastating effects on the environment.

Delivering his inaugural lecture on 22 August 2022 – a first for the Qwaqwa Campus in many years – Prof Geofrey Mukwada of the Department of Geography at the University of the Free State (UFS) Qwaqwa Campus painted a picture of the long-term effects of climate change on ecological, social, and economic aspects of the environment. The effects of climate change are being felt in all regions of the world, and the Drakensberg region in particular is beginning to bear the brunt.

Elevation-dependent warming a threat to socio-ecological systems

Introducing his topic, The last days of plenty: an assessment of elevation-dependent warming in the Drakensberg Mountain region between 1980 and 2018 and its potential implications for social-ecological systems in the region and downstream communities, Prof Mukwada said ‘last days’ was a euphemism used figuratively to imply the impending loss of environmental resources in the mountains because of climate change.

According to Prof Mukwada, elevation-dependent warming in the Drakensberg would pose serious implications for the overall rural livelihoods, regional trade, and biodiversity conservation.

“The Drakensberg Mountains is made up of a chain of several mountains and is home to a lot of activities. It is important for rural livelihood, including agriculture, cultivation of different forms, fisheries, and tourism, and if the climate is therefore changing and elevation-dependent warming is taking place, we see a threat to socio-ecological systems in many ways.”

In his lecture, Prof Mukwada discussed the three-decade-long investigation to determine if elevation-dependent warming is taking place at several points of the mountains, and to assess its environmental implications for the region and downstream communities. Using a time-series analysis standardised precipitation and evaporation index (SPEI) and monthly maximum temperature and locational and elevation data, the investigation monitored climate change trends between 1980 and 2018.

Development of research-based solutions

He said results did not confirm the existence of elevation-dependent warming in the Drakensberg Mountain region, but statistically significant evidence has shown that the region is becoming warmer and facing increasing aridity.

“It is worrisome in the sense that even such a small change can have devastating effects on the environment.”

In order to avert these problems, Prof Mukwada said a special climate adaptation plan for the region was necessary. The university plays a key role in this, as it can provide guidance on the process of redefining knowledge, scientific understanding and truth, in order to promote sound mountain development interventions and programmes. “We need to shift towards research-based solutions.”

Prof Mukwada is a C2 NRF-rated researcher with expertise in the application of remote sensing and geographic information systems (GIS) in integrated scientific and multidisciplinary environmental research.

More grey areas than just black and white in history?

Very few people understand that their actions and views within a territory stem from their roots or history. To enlighten the reading man on the composition of his base and the intricacies of the powers that are at play, is the work of historians.

Dr Abraham Mlombo is one of these historians, stationed within the International Studies Group at the University of the Free State (UFS).

This research group consists of postgraduate researchers, postdoctoral fellows, and academic staff that focus on African history, although they depart from more traditional study methods  a more global perspective. To date, Dr Mlombo's research examined the historical relations between South Africa and Southern Rhodesia. It was a broad study of the political, economic, social, and cultural relations from 1923 to 1953. He plans to continue by truly exploring the connections between South Africa and the region, and how they shaped one another. Dr Mlombo's interests in cross-border history and politics were inspired by his master’s degree in Political Science at Stellenbosch University. He researched his PhD at the UFS.

He draws energy for his work from the people surrounding him, and likes to be part of new experiences with people from different backgrounds. He feels such environments shape the way one works, as well as one’s world view. Dr Mlombo hints that sometimes, and specifically in South Africa, people focus very narrowly on their history and forget that many international links are at play. He sees his work as a historian to help open people's horizons.

Dr Mlombo suggests that future research should include a more critical analysis of how things unfolded during the second half of the 20th century. Writings should include more social- and people-oriented history, because he thinks there are more grey areas than just black and white. Many more interrogations must also follow into the assumptions of historical events and the individuals who played the greatest roles in Southern Africa.
