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.

“What do Africans have to say about the remaking of the global order?” was the opening question of Prof Tim Murithi’s lecture which was hosted by the Centre for Africa Studies (CAS) of the University of the Free State (UFS) to celebrate Africa Day on 25 May 2016.

The annual Africa Day Memorial Lecture, entitled: Africa and the Remaking of the Global Order, doubled as Prof Murithi’s inaugural lecture. He is CAS’s newly-appointed Extraordinary Professor, as well as the Head of the Justice and Reconciliation in Africa Programme at the Institute for Justice and Reconciliation in Cape Town. He made a compelling argument for the need for Africa to exert an active influence on international narratives of peace, governance, justice, and reconciliation.

“If we are waiting for American leadership to get us out of the quagmire of a situation we are in, we will be waiting for a long time,” said Prof Murithi.

The Head of the Centre, Prof Heidi Hudson, concurred with Prof Murithi’s suggestion of devising African solutions for African problems. She quoted Audre Lorde’s well-known assertion that “The master’s tools will never dismantle the master’s house.”

Remembering 1963
Over five decades ago, on 25 May 1963, the Organisation of African Unity was formed, and was renamed the African Union in 2002. Africa Day marks this pivotal point in the continent’s history. On this day, we reflect on the continent’s journey into democracy, peace, stability and socio-economic development. It is also an opportunity to celebrate African identity and heritage.

Continent-building dialogues
The UFS Sasol Library celebrated Africa Day with a book launch. Facets of Power. Politics, Profits and People in the Making of Zimbabwe's Blood Diamonds by Tinashe Nyamunda is a reflection of some of the challenges that Zimbabwe continues to face. It details the disadvantaged position which the country finds itself in due to greed, maladministration, and corruption, despite possessing large deposits of minerals.

In celebration of Africa Month, CAS has held a series of lectures by esteemed scholars from across the globe.  Earlier in the month, Prof Henning Melber presented lectures on Namibia’s independence and the African middle class. Kevin Bloom and Richard Poplak unpacked the issues surrounding Africa’s continental shift, while Prof Joleen Steyn Kotze focused on the possible fall of the African National Congress.
