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.

A publication in which the infrastructure developments at the UFS are portrayed, was published this year. This publication celebrates the enormous development projects undertaken.

Much has been done this past year to improve the infrastructure of our Bloemfontein and Qwaqwa Campuses with several buildings being built, some renovated and improvements made. Attention was specifically given to the growing need for lecture hall facilities and office space.

Some of the developments on our Bloemfontein Campus include: a brand-new entrance in Nelson Mandela Drive; a Memorial for Women and a Botanical Garden; a building for teacher education opposite the UFS Sasol Library; a building for our Faculty of Health Sciences opposite the Francois Retief Building; a Clinical Skills Centre for Allied Health Professions (the first in the country); and a building for our Faculty of Economic and Management Sciences between the Flippie Groenewoud Building and Wynand Mouton Theatre.

On our Qwaqwa Campus a building for teacher education is being constructed and some of the laboratories were refurbished and upgraded. More student accommodation is also well underway. A village development of four housing units that will accommodate 1000 students will be constructed on our Bloemfontein Campus.
Renovations and extensions were also made to some of the existing buildings such as the Architecture Building, the Biotechnology Building, the Department of Chemistry, the Stef Coetzee Building, the foyer of the Odeion, the Wynand Mouton Theatre and the Callie Human Centre. A staff restaurant has also been established on the Bloemfontein Campus and the building of ‘Little Professors’, a nursery school, is well underway.
“A building not only signals value to the outside; it also builds value on the inside. That is why it is important to notice how space has been organised and allocated to enhance the building of a community and to give academics, students and communities a sense of belonging to the university,” says Prof. Jonathan Jansen, our Vice-Chancellor and Rector.

The funding for most of the projects was made possible with an infrastructural grant from the Department of Education and Training.
