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.”

South Campus delivers out-of-the-box solutions

The IDEAS Lab on our South Campus supports learners in 83 schools by means of academic videos transmitted via the Internet Broadcast Project (IBP) and its own custom-built All-in-One (AIO) device. The project is a collaboration between UFS and the Department of Education in the Free State. It includes support for Mathematics, Physical Science, Life Science, Economics, Accounting, and Geography.

The AIO was purpose-built by the team at IDEAS Lab to facilitate the delivery of video lectures from highly-qualified teachers to identified schools. It comprises a projector, speakers, and a computer, which are housed in a custom-made, hard-wearing frame. The AIO is then set up at each school to which lessons are broadcast.

On-the-job training for educators

Educators have not been overlooked, either. UFS was the very first university to provide an Advanced Certificate in Teaching in a fully digital format, the ACT Online programme. It is designed for practicing teachers to upskill themselves in order to better address the needs in the classroom, not only advancing their career, but strengthening their knowledge, competencies, and subject specialisation as well. Ultimately, this leads to an improved quality of education, which has a profound impact on multitudes of students around South Africa.

CSIR joint initiative

Coupled with these projects is a new joint initiative termed ICT For Education. This project sees the CSIR collaborating with the national Department of Education, the Department of Rural Development and Land Reform, and the UFS. For this project, 24 primary and secondary schools in South Africa were identified to promote technological advancement in the education sector. Tablet computers have been allocated and already deployed at these schools, to learners as well as nearly 400 teachers.

South Campus is involved in the training of the teachers and learners in the use of the tablets in the classroom and other educational opportunities. In addition, training for 48 unemployed young people who will be providing first-line support began in March at a school in Thaba Nchu. The course on IT support is structured in such a way that anyone in the community can take it, starting out with topics such as My role in the community.
