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.”

Fourth Reconciliation Lecture: Audio

McGivern: speech (pdf)

The UFS Annual Reconciliation Lecture brings leaders, scholars, and the broader community together in a shared vision for social change and conflict transformation. This event is organised by Prof Pumla Gobodo-Madikizela, Senior Research Professor in Trauma, Forgiveness and Reconciliation Studies. In 2012, Nadine Gordimer, Nobel Prize Laureate for Literature, was the first speaker to deliver the lecture. This year, at the Fourth Annual Reconciliation Lecture held on the Bloemfontein Campus, Colm McGivern, Director of the British Council in South Africa, continued the legacy.

Doing what must be done
'I get down on my knees and do what must be done
And kiss Achilles' hand, the killer of my son.'
(Ceasefire by Michael Longley)

Using this poem to powerful effect, McGivern showed what reconciliation asks of each and every citizen: to do what must be done. “I think that peace and reconciliation are mutually dependent,” he said. “You can’t maintain one over the long run without attending to the other.”

South Africa’s history has tracked along a similar path to that of Northern Ireland. “And lessons from other places can be powerful and instructive,” McGivern said. Sometimes reconciliation needs a focal point for people to clearly see its power, as Madiba has for South Africa. But at other times, reconciliation needs everyday citizens to “kiss Achilles’ hand’”.

McGivern mentioned Candice Mama and her family, who  have recently forgiven Eugene de Kock,. Or as Gordon Wilson did after his daughter, Mary, died holding his hand in the 1987 Enniskillen bombing in Ireland. In a TV interview mere hours later, Wilson forgave the killers of his daughter, and  hope rippled across Ireland.

Learning from others
“People’s capability,” McGivern said, “to reconcile their own differences, however stark, can be boosted by learning from others in other places, internationally or perhaps just beyond their own identity group.” A powerful truth now being pursued in a joined initiative between the British Council and Teaching Divided Histories.

As an example, McGivern referred to the short film, ‘In Peace Apart’ where one Catholic and one Protestant girl decide to swop school uniforms. Harnessing the potential of moving images and digital media, the initiative enables teachers to explore contentious issues of history and identity in the classroom. This international field of conflict education draws lessons “from activities in Sierra Leone, India, Lebanon, and, of course, South Africa.”

Resuscitation of the national spirit of magnanimity
Here in South Africa, Archbishop Desmund Tutu has “called for a resuscitation of the national spirit of magnanimity and common purpose”, McGivern quoted. In the book, 80 Moments that Shaped the World, South Africa appears four times, McGivern pointed out. And as Archbishop Tutu wrote in the foreword of the book, “no act is unforgivable; no person or country is beyond redemption and the world needs more people to reach out to one another.”
