Liezel Rudolph, lecturer and researcher in the Department of Geography at the University of the Free State (UFS), is strongly convinced that the Southern Hemisphere’s past glacial cycles will provide valuable insights to help predict and prepare for future climate change. Climate is changing fast and the magnitude of change we have seen over the last 30 years has taken a hundred or several hundred years to occur in the past. 

It is not only temperatures that are rising, but changes in wind patterns, rain cycles, oceanic circulation, etc., are also observed. As we do not know how the earth will respond or adapt to such rapid and drastic changes in climatic patterns, this poses various threats.

Link between landscape responses and climate change

Rudolph focuses her research on reconstructing the past climate of Marion Island. 

She had the wonderful opportunity to visit the island for the past three years with study and project leaders, Profs Werner Nel from the University of Fort Hare and David Hedding from UNISA, she departed on a ship to Marion Island to conduct fieldwork.They published their research findings of fieldwork conducted in 2017 and 2018.  

According to Rudolph, research in Antarctica, the Southern Ocean, and islands such as Marion Island is very important. South Africa is the only African country with research stations that have the ability to explore these regions.

“Marion Island has many landforms that could only have been created by glacial erosional or depositional processes, with glaciers currently absent from the island. To determine when the island was last in a full glacial period, we date the formation ages of these landforms.”

“In the short time we have been visiting the island, it was impossible to notice any drastic changes in the island climate. That is why we use these very old landforms to tell us more about periods before humans visited the island,” she says. 

Rudolph believes that understanding the link between landscape responses and climate change of the past can help to better predict some of the climate change processes that are currently threatening the planet.

“There’s a principle in geography called ‘uniformitarianism’, whereby we assume that the earth-surface processes we observe today, are the same as those that have been active in the past,” says Rudolph.

As scientists, they thus look at evidence of past geomorphic processes (which remain in the landscape in various forms, e.g. residual landforms, stratigraphic sequences, etc.) to piece together what the past climate was like. In the same way, they also use this principle to predict how certain earth processes will change in the future, along with climate changes.

“In return, we understand how the climate and the earth’s surface interact, and we can better predict how the earth will respond to climate change,” Rudolph adds. 

Society to play its part in climate change

In the long run, we as the public should play our part in readying society for the effects of climate change. 

Rudolph says society can play a positive role in terms of climate change by educating themselves with unbiased, scientifically sound information on the true state of climate change and by responding within their own spheres of influence.

“Don’t leave everything up to politicians and policy. As the public, you can start to make progress by assessing the effects that climate change may have on your industry, business or society, and strategise on how to adapt your processes to deal with these changes.”

“Be responsible with our natural resources, reduce your waste, support local businesses that are sustainable, and volunteer at a local environmental protection/clean-up organisation. All the small efforts will eventually add up to substantial change,” she says.

UFS Music rises to academic prominence
2007-10-18

Four postgraduate students gave prominence to the Music Department of the University of the Free State by having four academic articles published by accredited journals, and a fifth published in an international online journal.

It is the first time that a tertiary music institution in South Africa has had so many postgraduate studies published in one year, says Prof Martina Viljoen.

The students who worked under Prof Viljoen's supervision are Hanna van Schalkwyk, senior lecturer in singing at UFS; Ronella Jansen van Rensburg, part-time music lecturer and founder of the Sentraal-Kultuurakademie (Central Culture Academy); Elene Coetzer, also a part-time lecturer and involved in the Mangaung String Project; and Lizabé Lambrechts, who is still studying full-time.

Hanna and Ronella attained their master's degrees and Lizabé honours.

Hanna's research on the unique and at times unorthodox philosophy in singing and method of the pedagogue in singing Sarie Lamprecht (1923-2005) is published in the Tydskrif vir Geesteswetenskappe (Journal for the Humanities).

The study documents interviews held with Lamprecht over more than two years as well as conversations with her most prominent students.

Ronella's study on the relationship between emotional intelligence and musical performance anxiety is divided into two successive articles in the journal Musicus.

Dr Adelene Grobler, Epog director at UFS, was Ronella's co-supervisor.

Elene conducted a qualitative investigation into the Mangaung String Programme in which the social value of this teaching programme is emphasised.

She documented the responses of learners, parents and teachers who are involved in the project. Her article is published in the Journal of the Musical Arts in Africa.

Lizebé reached out to pop culture for her research and wrote about no less a person than the controversial shock-rock-icon Marilyn Manson.

Her study serves as a model analysis for educational work that focuses on popular culture as a didactic instrument.

In this respect Manson's music, which is frequently slated as vulgar or disturbing, is shown as aggressive social comment.

Lizabé's article, which throws light on Manson's bisexual identity, was published as a full-length monograph in the first edition of the overseas online noncejournal.

In 2005 the Department of Music also excelled when it was the first academic music institution in South Africa that published international congress proceedings as a subsidised collection.

The collection contained eminent international authors and was published under the guest editorship of Viljoen.
