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.”

Marikana and its subsequent economic and political consequences
2013-05-30

The Marikana incident is a bitter moment for South Africa's new political establishment; a tragedy on the same scale as Sharpeville and the Soweto massacre.

This is how Prof Adam Habib, Vice-Chancellor and Principal designate of the University of the Witwatersrand, described the sorrow during the CR Swart Memorial Lecture hosted by the Department of Political Studies and Governance.

Speaking on the topic The Post-Marikana landscape in South Africa, Prof Habib and Dawie Roodt, Chief Economist and Director of the Efficient Group, gave their views on the political and economic challenges confronting the country.

Prof Habib, a well-known political commentator, explained to the fully-packed CR Swart Auditorium how this tragedy provoked a national soul-searching.

Referencing from his highly-anticipated book South Africa's Suspended Revolution, Hopes and Prospects, Prof Habib said the difficulty Marikana poses is the challenge of inequality. According to him, inequality is the single biggest challenge of the South African society. He firmly believes that taking responsibility for poverty is a moral necessity. "Addressing poverty is absolutely crucial if we want to be a humane society."

In his presentation, Roodt informed the audience regarding recent data on population growth, unemployment and dependency ratios. These statistics gave an indication of how the country is doing. The economist said the only way to address unemployment, inequality and poverty is through economic growth.

"If we want to do something about inequality, we have to do something about skills – particularly skills for women. We must make it easier for people to get jobs," Roodt emphasised.
