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.

Teachers should deal with diversity in education - Prof. Francis

Prof. Dennis Francis, the Dean of the Faculty of Education at the University of the Free State (UFS), recently delivered his inaugural lecture on Troubling Diversity in South African Education on the Main Campus in Bloemfontein.

He urged teachers to be open to what “diversity” might mean in a particular context and how diversity relates to either inclusion or exclusion.

“An approach that promotes the inclusion of all must be based on an understanding of how exclusion operates in ways that may have typical patterns of oppression, but differ in the specific ways that exclusion is expressed and becomes normalised in that context,” he said.

“The good teacher thus seeks to understand how these forms of exclusion may develop in the school’s context and respond through taking thoughtful action to challenge them. It may require creating a climate that enables the silent to speak and recognising that not all groups communicate in exactly the same ways.”

He said teachers also had to affirm the experiential base of learners and students. He said there was an assumption that students would be more effective practitioners if their own experience were validated and explored.

“It is crucial that the students’ own history is treated as valuable and is a critical part of the data that are reflected,” he said. “Equally important is that such stories and similar activities are intentionally processed to enable students to make the connections between personal experience and relevant theory.”

He also urged them to challenge the ways in which knowledge had been framed through oppression.

“Schools are often characterised by messages that draw on one or another form of oppression. Thus, expectations are subtly or in some cases unsubtly communicated, e.g. that girls are not good at physics, or that, while white learners are strong in abstract thought, African learners have untapped creativity, and so on,” he continued.

“For someone to integrate into their role as educators a commitment against oppression means confronting obstacles that one may previously have shied away from, such as challenging authority, naming privilege, emphasising the power relations that exist between social groups, listening to people one has previously ignored, and risking being seen as deviant, troublesome or unpopular.”

Furthermore, Prof. Francis said dealing with diversity in education was always affectively loaded for both students and teachers. He said in South Africa one injunction from educators was to be “sensitive” and thus avoid risking engagement with the contentious issues around imbalances of power.

“If both students and teachers are to confront issues of oppression and power in any meaningful way, we need to design more purposely for the difficulties they will encounter, for example, creating a classroom environment that promotes safety and trust so that all students are able to confront and deal with prejudice and discrimination. Classroom environments will need to balance the affective and cognitive in addressing issues of diversity and social justice,” he added.

He also said that teachers should recognise the need to complement changing attitudes with attempts to change the structural aspects of oppressions.

“To prevent superficial commitments to change, it is important for students to explore barriers that prevent them from confronting oppressive attitudes and behaviours. In this way students are able to learn and see the structural aspects of oppression,” he said.

“Equally important, however, is to get students to examine the benefits associated with challenging oppression. A fair amount of time must therefore be spent on developing strategies with students which they will be able to use practically in challenging oppression.”

He also advised educators to affirm the capacity of staff and learners to act and learn in ways that do not replicate patterns of oppression.

“Many South African schools have survived both the harsh repression of apartheid and the continuing legacy of oppression of various kinds. Despite that, we are often as educators made aware of the ways in which young people in particular affirm themselves and each other in creative and confident ways,” he concluded.
