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.”

Co-architect of peace and reconciliation in Northern Ireland to present Annual Reconciliation Lecture today
2015-03-03

Colm McGivern, Director of the British Council in South Africa

To emphasise the University of the Free State’s Human Project, the UFS has positioned itself as an institution that is recognised across the world not only for excellence in academic achievement, but also in human reconciliation. The Annual Reconciliation Lecture, whose organising committee is chaired by Prof Pumla Gobodo-Madikizela, is a unique and major initiative to enhance this important vision of our university.

This year, Colm McGivern, Director of the British Council in South Africa, will present the Fourth Annual Reconciliation Lecture at the Centenary Hall on Thursday 5 March 2015.

Colm McGivern was brought up in Northern Ireland at the height of the conflict that has come to be known as the ‘Troubles.’ His early experiences of conflict, sectarianism, and living in a divided society have driven his career, and his personal commitment to peace-building and promoting reconciliation.  He was a student leader at Queen’s University in Belfast during the time of the first IRA Ceasefires in the 1990s, and then worked in the Higher and Further Education sectors, and at a community level with peace-building groups across Northern Ireland and internationally. He was Director of the British Council in Northern Ireland for four years and, in that role, facilitated discussions between divided communities before and during the Ceasefires and Peace Process, with a particular focus on bringing young people together across Ireland.

In his role as Director of the British Council, McGivern has created thousands of cultural and educational connections between the UK and SA. Every year, he ensures that young South Africans can get access to educational and cultural opportunities that are life-changing while deepening their connection with the UK.

A highlight of this year’s lecture will be a performance by musicians from the Odeion School of Music, Tumi Ntantiso (soprano), Bertha Menyatso (mezzo-soprano), Malefetsane Mofokeng (baritone), and Cezarre Strydom (piano). They will be performing works from ‘Tales of Hoffmann’ by Jacques Offenbach, among others.

Members of the public and media are welcome.
