All mountains around the world have native and non-native species that are expanding their ranges quite dramatically; however, little research has been conducted towards understanding the long-term redistribution of species and the effects of global change on biodiversity.


The Afromontane Research Unit (ARU) on the University of the Free State Qwaqwa Campus – as part of the Mountain Invasion Research Network – has secured a two-year EU Horizon 2020 project under the Department of Science and Innovation, which will be looking at the mechanisms underlying the success and impact of range-expanding species on biodiversity and ecosystem functioning.

On Monday 19 July 2021, the ARU took a few of its researchers on a scenic helicopter ride to the summit of the Drakensberg for an alpine field-experiment site inspection of the Mont-aux-Sources peak, one of the highest sections of the Drakensberg range. This site has been identified for the project which the research unit will be leading on mountain research.

ARU Director, Dr Ralph Clark, said the project would explore the effects of global change, biological invasions (when species invade new geographic regions), as well as climate and land-use change. He said experiments were needed to explore the various possibilities and to test the extent to which species respond to experimental treatments. The project would therefore be conducting experiments for two years using open-top chambers – causing an increase in temperature of 3 or 4 degrees to what you find naturally – on plant species from lower down to the top of the mountain, to see how they function. “This will give us an idea of whether they will be able to survive in global warming scenarios. If temperatures get warmer, we might start seeing a lot of plants up here that we wouldn’t otherwise find here.”

Dr Clark said little is known about the long-term monitoring of species distribution and the effects of global change. Implementing the project in the Maloti-Drakensberg alpine area will therefore put the area in the global mountain research arena. The elevational gradient in the Maloti-Drakensberg Mountains provides space to explore the key processes underlying the variation in species elevation with climate change. “One of the things we don’t know much about are alpine systems. We are hoping to establish a long-term alpine research site and try to add as many studies as we can. The more science we can bring up here, the more we can know about mountain life. What happens on mountains has a lot of impact on social dynamics.

“This project is looking to see what is driving range expansion. Every mountain has its own context. In the Swiss alpine, fires are not a big factor, but fires are one of the biggest factors on our mountains. Some of our native and non-native species are therefore fire-driven, so as fire increases, you might have them spreading faster.”

“It doesn’t matter where a concept originates from if it works. The problem arises when the concept does not work.”

These were the words of Prof Gareth Austin in his address at the Young Scholars Initiative (YSI). His keynote focused on the “Economic History in Africa’s Decolonisation and Development”.

The African economic history

Prof Austin, a professor in Economic History at the University of Cambridge, discussed how African economic history has always been about development, and also gave a brief periodisation of the economic historiography of Africa.

In his closing remarks he focused more on history and economics. “Economics is a sensible approach to take, where history matters because of the sense of context.”

Reflecting on the African experience

A total of 65 young and senior scholars from five continents attended the conference Decolonising Africa? The Economic History of Development, hosted by the YSI in partnership with the International Studies Group at the UFS.

The conference, held from 8 to 9 June 2017, provided an opportunity to reflect on the African experience from an historical perspective and to assess the current position of the continent in the global economy. It discussed new themes in development, such as the role of women, minorities, and entrepreneurs.

The conference focused on how the business community has operated in an Africa that still faces inequalities and unfair terms of trade and lacks a unified political will.
