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.

Twenty years of the constitution of South Africa – cause for celebration and reflection
2016-05-11

Judge Azar Cachalia

The University of the Free State’s Centre for Human Rights and the Faculty of Law held the celebration of the twentieth anniversary of the adoption of the South African Constitution on 11 May 2016 on the Bloemfontein Campus.  Students and faculty members celebrated and reflected on not only the achievements of the constitution but also on perspectives regarding its relevance in modern society, and to what extent it has upheld the human rights of all citizens of South Africa.

The panel discussion started with a presentation on the pre-1996 perspective by Judge Azar Cachalia of the Supreme Court of Appeal.  Judge Cachalia reflected on his role in the realisation and upholding of the constitution, from his days as a student activist, then as an attorney representing detainees during political turmoil, and currently as a judge: “My role as an attorney was to defend people arrested for public violence. My role as a judge today is to uphold the constitution.”  He stressed the importance of the constitution today, and the responsibility institutions such as the police service have in upholding human rights.  Judge Cachalia played a significant role in drafting the new Police Act around 1990, an Act which was to ensure that the offences perpetrated by the police during apartheid did not continue in the current democratic era. Further, he pointed out that societal turmoil has the potential to make society forget about the hard work that was put into structures upholding human rights. “Constitutions are drafted in moments of calm.  It is a living document, and we hope it is not torn up when we go through social conflict, such as we are experiencing at present.”

Thobeka Dywili, a Law student at the UFS, presented her views from the new generation’s perspective.  She relayed her experience as a student teaching human rights at schools in disadvantaged communities. She realised that, although the youth are quite aware of their basic human rights, after so many years of democracy, “women and children are still seen as previously disadvantaged when they should be equal”. She pointed out that, with the changing times, the constitution needs to be looked at with a new set of eyes, suggesting more robust youth engagement on topics that affect them, using technology to facilitate discussions. She said with the help of social media, it is possible for a simple discussion to become a revolution; #feesmustfall was a case in point.

Critical perspectives on the constitution were presented by Tsepo Madlingozi of University of Pretoria and University of London. In his view, the constitution has not affected policy to the extent that it should, with great disparities in our society and glaring issues, such as lack of housing for the majority of the poor.  “Celebration of the constitution should be muted, as the constitution is based on a decolonisation approach, and does not directly address the needs of the poor. The Constitutional Court is not pro-poor.”  He posed the question of whether twenty years on, the present government has crafted a new society successfully.  “We have moved from apartheid to neo-apartheid, as black elites assimilate into the white world, and the two worlds that exist have not been able to stand together as a reflection of what the constitution stands for.”

Prof Caroline Nicholson, Dean of the Faculty of Law, encouraged more open discussions, saying such dialogues are exactly what was intended by the Centre for Human Rights. She emphasised the importance of exchanging ideas, of allowing people to speak freely, and of sharing perspectives on important issues such as the constitution and human rights.
