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 students win Innovation prize

Prizes to the value of R100 000 were recently handed to students in the Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS) during a prize winners function of the National Innovation Competition.
“The competition is sponsored by the Innovation Fund, which was established by the national Department of Science and Technology and is managed by the National Research Foundation (NRF). The competition seeks to develop innovation and entrepreneurship amongst students in higher education institutions,” said Prof. Teuns Verschoor, Vice-Rector of Academic Operations at the UFS.

Most universities in South Africa take part in the competition. “The first phase of the competition is per university where students can win prize money to the value of R100 000. The three winners then compete in the national competition, where prize money to the value of R600 000 can be won,” said Prof. Verschoor.

Eight teams from the Faculty of Natural and Agricultural Sciences competed in the local competition. The teams had to submit a business plan, which was judged by six external adjudicators.

The winning team from the Department of Microbial, Biochemical and Food Biotechnology submitted their business plan with the title: “Using bacteriophages to combat specific bacterial infections in poultry". The team, consisting of Kasey Kakoma from Zambia, Lehlohonolo Mathengtheng from South Africa, and Ji-Yun Lee from South Korea, were awarded R50 000 in cash. All three students are Master’s degree students in Microbiology in the Veterinary Biotechnology Research group at the UFS.

The team who came second was from the Department of Physics with team leader Lisa Coetzee and they received R30 000. The title of their project was “Light of the future”. The third prize of R20 000 went to Lizette Jordaan of the Department of Chemistry with a project entitled: “Development of a viable synthetic route towards a natural substrate with possible application in the industry”.

Prof. Gerrit van Wyk, former dean of the UFS Faculty of Natural and Agricultural Sciences and consultant for Technology Transfer Projects, annually drives this competition.

In his announcement of the winners of the first phase of the 2007 National Innovation Competition, Prof. Herman van Schalkwyk, Dean of the UFS Faculty of Natural and Agricultural Sciences, said innovation and entrepreneurship are important to stimulate and create sustainable economic growth in South Africa. “Through this competition universities get the opportunity to show to South Africa its capabilities in the arena of innovation and commercialisation of ideas,” he said.

To proceed to the second phase of the competition, the business plans of the three finalists from each qualifying higher education institution will be submitted for the national competition. The best three students from each participating institution will exhibit their innovations at the national awards ceremony early in 2008. The top ten entrants and subsequently the best three business plans from the total entries will then be short listed. The prize money won at the national competition has to be used for the commercialisation of the project or the founding of a company.
