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.

Prof Moffett’s third book provides comprehensive guide to Basotho medicinal plants

Prof Rodney Moffett has recently published his third book, Basotho Medicinal Plants – Meriana ya Dimela Tsa Basotho. This latest offering deals only with medicinal uses and is based on the data from his first book, Sesotho Plant and Animal Names and Plants Used by the Basotho.

“The latest book came about after a Sesotho language advisor in the Free State Department of Education suggested that there was a need for the medicinal uses of plants by the Basotho to be documented in the vernacular. In a situation where there is an almost total lack of scientific literature in the vernacular, the greatest value of this book therefore, is that it provides a comprehensive guide to the medicinal uses of plants in Sesotho,” said Prof Moffett, Honorary Research Associate in the Department of Plant Sciences on the Qwaqwa Campus.

Book lists names of plants in Sesotho
“It comprises two parts. Part one lists the medicinal categories and plants used, and part two lists the medicinal uses arranged according to the Sesotho names of the plants. It is easy to read, as the information is presented alphabetically with the Sesotho name first, followed by the scientific name and usage thereof. Because a plant often has more than one Sesotho name, the scientific name is included to identify it.”

Prof Chris Nhlapo, Deputy Vice-Chancellor of the Cape Peninsula University of Technology, and Prof Ntsamaeeng Moteetee from the University of Johannesburg are impressed with the book, respectively saying that it assists in documenting the deep indigenous knowledge of the “proud tradition of the Basotho Nation” and it is “an important contribution to the documentation of medicinal plant uses”.

The title of Prof Moffet’s second book was A Biographical Dictionary of Contributors to the Natural History of the Free State and Lesotho.

Prof Moffett was honoured with a Lifetime Researcher Award during the Academic and Research Awards on the Qwaqwa Campus in November.
