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.”

Disaster risk management centre of the UFS serves on UN specialist committee

The Director of the Disaster Management Training and Education Centre (DiMTEC) at the University of the Free State, Dr Andries Jordaan, has been invited to serve on a UN special committee by the Secretary-General of the United Nations.

Dr Jordaan took part in the Expert Workshop on Climate Resilience in Geneva, Switzerland, on 22-23 June 2015.

In preparation for COP 21, which takes place later this year in Paris, the United Nations must draw up a situation report for a universal climate agreement between all the world’s nations. In order to advise the United Nations and the Secretary-General, and to prepare for the UN’s resilience initiative that will be launched during this important international gathering, a small  team of approximately 20 experts and scientists from all over the world have been chosen to review the concept of the project. This group of experts will help to revise the original concept for the project.

According to Dr Jordaan, the Sectretary-General of the UN will be launching a ‘resilience initiative’ that is aimed at promoting resilience in climate-related risks.

Jordaan says it is an honour for him to represent the UFS and DiMTEC on such a specialist committee. “For me, it is recognition of the contribution we make in Africa and the world to disaster risk and climate adaptation,” he says.

DiMTEC is proud to be at the forefront of disaster management training in Africa. The centre has close ties with institutions of the United Nations, such as UNU-EHS, UNU-Flores UNOOSA, UNSPIDER, UNEASCO, UNEP, UNCCD, UNISDR and UNDP, among others.

DiMTEC strives to inform the public about disaster risk reduction through education. The centre’s master’s and post-graduate degrees in disaster management, as well as short courses and research, are of the highest standard.
