Dr Falko Buschke says the iconic sandstone cliffs of the eastern Free State are key to protecting wild plants and animals from climate change.

The iconic sandstone cliffs of the eastern Free State are often the focus of paintings and postcards. Now, new research shows they also protect wild plants and animals from climate change. This finding is the outcome of a collaborative research effort by the University of the Free State (UFS); BirdLife South Africa; the Vrije Universiteit Brussel and KU Leuven, Belgium, which has recently been published in the journal Biological Conservation.

Mountains key for climate change mitigation

The study, led by Dr Falko Buschke from the Centre for Environmental Management UFS, used satellite data from NASA to track the ecological effects of wet and dry seasons, including the record drought of 2015/16. This showed how vegetation on the cool and moist mountain slopes was less affected by dry spells.

The complex physical terrain allows moisture to accumulate in the shaded parts of the south-facing slopes and ravines. This creates cool and moist habitats for plants and animals that wouldn’t survive in the rest of the hotter and drier landscape.

The team also discovered that these positive effects of mountains do not end at the foot of the mountain, but extend at least 500m into the flatter lowlands. “Presumably because water and nutrients accumulate in these surrounding buffers due to run-off,” says Dr Buschke.

Butterflies find safety on mountains

In addition to their high-tech analysis of the area, the team also relied on old-fashioned fieldwork to monitor butterflies over two years. “The data showed us how these insects find safety on mountains during harsh climate conditions and can then recolonise the rest of the landscape after conditions improve,” explains Dr Buschke. “This gives us clues on the best way to protect nature,” he adds. 

This study took place in the Rooiberge-Riemland Key Biodiversity Area (KBA), an area significant for maintaining global biodiversity. Several species of insects, reptiles, birds and mammals here occur nowhere else on earth. “If they disappear here, they will go extinct from the whole planet forever,” says Dr Falko Buschke. 

Despite its ecological significance, most of the area is covered by commercial farmland. So, the next stage of the project is exploring ways of protecting these important habitats while ensuring that farmers can continue producing food and supporting rural livelihoods. 

Farmers hold the key to preserving biodiversity,” says Dr Buschke, “so conservation scientists need to work closely with them to ensure that we protect species for future generations.”

Lecture by Judge Albie Sachs: ‘Sites of memory, sites of conscience’
2015-03-23

Judge Albie Sachs

Human rights activist and former Constitutional Court Judge, Albie Sachs, will deliver a public lecture on the Bloemfontein Campus. The topic of his discussion will be ‘Sites of memory, sites of conscience’. This lecture will form part of a series that focuses on how the creative arts represent trauma and memory – and how these representations may ultimately pave the way to healing historical wounds.

The details of the event are:
Date: Thursday 26 March 2015
Time: 12:30
Venue: Albert Wessels Auditorium, Bloemfontein Campus
RSVP: Jo-Anne Naidoo at Naidooja@ufs.ac.za
A South African Sign Language interpreter will be present at the event.

Joining Judge Sachs on stage as respondent will be Dr Buhle Zuma, a young scholar and lecturer at the University of Cape Town's Psychology Department.

Expressing experiences of trauma
Judge Sachs is no stranger to the use of the arts as a way of expressing the inarticulable and overwhelming experiences of trauma. Targeted as an anti-apartheid freedom fighter, he lost his right arm and was blinded in one eye in a car bomb attack in 1988. As a judge of the Constitutional Court, he spearheaded conversations about the role of the arts in our constitutional democracy. This has led to the installation of some of the best artworks by South African artists at the Constitutional Court.

Vice-Chancellor’s Lecture Series on Trauma, Memory, and Representations of the Past
This lecture will launch of the Vice Chancellor’s Lecture Series on Trauma, Memory and Representations of the Past. It forms part of a five-year research project led by Prof Pumla Gobodo-Madikizela, funded by the Mellon Foundation. The event is hosted by the UFS Trauma, Forgiveness and Reconciliation Studies.

“One of the most remarkable aspects of trauma,” Prof Gobodo-Madikizela says, “is the loss of language, a moment of rupture that produces what some scholars have referred to as ‘speechless terror’. The arts, in all its forms – literary, performance, and visual – are a viable mechanism through which the unspeakable, traumatic past may be represented.”

These artistic forms of representing trauma are at the heart of this Vice-Chancellor’s Lecture Series. “We are interested not only in how experiences that transcend language are represented through the arts,” Prof Gobodo-Madikizela explains, “but also in probing the limits of trauma theory, and how the creative arts might be employed to bear witness in a way that may open up the possibility of healing.”

Dr Buhle Zuma
Former Mandela Rhodes scholar and one of the 2011 Mail & Guardian’s 200 Young South Africans, Dr Zuma is particularly interested in issues at the heart of our rainbow nation. His current research revolves around the question of freedom: what it means to be human for black people after centuries of dehumanisation, and the role of desire and fantasy in the political imagination of post-apartheid South Africa.
