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.”

In view of the environmental and social problems faced in South Africa today, researchers such as Dr Inge Konik are hard at work mapping these issues and seeking long-term solutions. Dr Konik,  a lecturer in the Department of Journalism, Media and Philosophy at the Nelson Mandela Metropolitan University (NMMU) shared her views in a presentation on 6 May 2016. She spoke about revaluing indigenous ways of life and subsistence-focused lifeways, linking this to materialist ecological feminism, or ecofeminism for short.

Dr. Konik’s presentation, hosted by the Department of Philosophy at the Bloemfontein Campus of the University of the Free State (UFS), was entitled: “Transversal reflections on ecological feminism and ubuntu.” The research underpinning the presentation derived from Dr Konik’s doctoral thesis which was supervised by Ariel Salleh (University of Sydney) and Andrea Hurst (NMMU).

Dr Konik’s research suggests that ecofeminism - which is a convergence between environmentalism and feminism - may hold the answers to the question of how we may work against environmental and social injustices. She also proposed that society look back toward subsistence communities of the past, and those currently being marginalized in our industrial societies, and linked the values evidenced in the practices of these communities to the African philosophty of ubuntu. In order to solve  complex contemporary challenges Dr Konik suggests that we combine these seemingly disparate theoretical frames - ubuntu and ecofeminism - by applying a transversal approach, which involves openness to dialogue  between traditions.

“My focus was on ecological feminism and critical theory and very specifically on South Africa, given the challeges South Africa faces - the environmental and social challenges and what kind of frameworks would be helpful,” said Dr Konik, who will officially become a postdoctoral research fellow at the department as of July 2016.

Prof Pieter Duvenage, Head of the Departement, stated that compelling research outputs are anticipated from Dr Konik as a fellow.
