The last days of plenty: Prof Mukwada delivers his inaugural lecture

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.

Many changes for Shimlas, says new captain

The University of the Free State (UFS) has a new group of rugby players, a new head coach, and a new captain.

This is how the Shimla skipper, Neil Claassen, summed up his team's approach to the 2016 Varsity Cup.

Although the UFS will start the tournament as defending champions, the 23-year-old Claassen believes that much has changed since 2015.

One of which is his appointment. The flanker, who can play lock as well, was recently appointed as Varsity Cup captain in his third series.

The former Springbok flanker, Hendro Scholtz, took over as head coach from Franco Smith, who is now the Cheetahs trainer. Mac Masina, former centre for the Lions, is a new assistant coach.

New year with more pressure

Because of all the changes, Claassen feels that the Shimlas will need a different approach to the 2016 tournament.

“There will definitely be more attention on us (as champions). However, the guys in the camp see it as a new year,” he said.

“There is pressure, but we don't focus on that too much.”

Previous leaders set example

According to Claassen, he has never before led a team for which he played.

“I didn't expect to be captain,” the former pupil of Paarl Gymnasium said.

“This is something new. I have played with good leaders like AJ (Coertzen) and Oupa (Mohoje) before, and will take forward what I have learned from them.”

He also believes that there are several senior players, such as the vice-captain, Pieter-Steyn de Wet, who will assist him in his leadership role.

Back from injury

Claassen has played Currie Cup, Vodacom Cup, U21 and U19 rugby for the Free State.

However, a knee injury kept him out of action for nine months and he missed the last three Varsity Cup matches of 2015.

He returned for a training match against the University of Johannesburg in Kroonstad on 23 January 2016. The Shimlas also played a warm-up match against the University of KwaZulu-Natal in Bethlehem on 16 January 2016.
