ARU pioneering mountain range-expanding project

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.”

The challenges of local governance highlighted at the JN Boshoff Memorial lecture

The annual JN Boshoff memorial lecture was hosted by the Faculty of Economics and Management Sciences in conjunction with the Department of Public Management on 21 August 2014. Mr Kopung Ralikontsane, Director-general of the Free State Provincial Government, presented the keynote address, ‘Challenges Facing Local Government in Service Delivery’.

In his opening remarks, Mr Ralikontsane gave the background of the South African municipal structures, the legal framework within which they operate and the challenges they are currently facing. He added that “local government is a sphere at the coalface of service delivery and if this sphere fails, South Africa would have failed to be a developmental state.”

He said the Free State provincial government has made great strides in developing local communities, with millions of rands invested in various development projects such as water and sanitation, electrification, roads and storm water structures, community facilities and solid waste disposal.

Local government is still faced with other challenges, though. He pointed out that public employees are subject to greater scrutiny and increased demands from citizens. As a result, they have to provide better services, but within stricter limits on resources. Conflict arises due to changing relationships between public servants and citizens, downsizing, restructuring and contracting out of government services and activities.

Despite the various structures implemented by local government, municipalities are serving an ever-growing population in an economic decline. Regulations have been put into place to devise credible Integrated Development Plans (IDPs) to improve municipal infrastructure, build competent management teams and strong operations and increase technical capacity for effective delivery of services.

Mr Ralikontsane invited students to join local government in crafting innovative solutions. “We know the problem, but we need to encourage you to join forces with your local government and tackle them.”

Mr Kopung Ralikontsane has served in local government for two decades and also serves as Head of Administration of the Free State Government and as Cabinet Secretary.
