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.”

Up to 60% of students do not have enough to eat
2013-11-15

 

15 November 2013

A report of the University of the Free State has revealed the shocking statistics that almost two-thirds of the students at the university don’t have enough money to buy food, and suffer from hunger during terms.

The study, conducted internally by the university’s Department of Nutrition and Dietetics, was a response to a growing international concern that students worldwide were not getting enough to eat. While studies were conducted in the USA and Australia, no similar research has been done in South Africa.

“There have been many studies on the impact of poor nutrition on school kids,” says Dr Louise van den Berg, Senior Lecturer in the Department of Nutrition and Dietetics, “but almost no research on university students. South Africa is, overall, a food-insecure country, and the university wanted to establish how widespread this problem is among our students.”

The reasons given by students invariably referred to a lack of money, as many students were also supporting families. Some students admitted they lacked the knowledge to feed themselves properly, some admitted to borrowing money to buy food, and some even admitted to stealing food to survive.

“This research has confirmed something we have suspected for a long time,” Dr van den Berg states.

A number of students disclosed that they were reluctant to resort to the university feeding scheme, as they were ashamed to admit they did not have money to buy food.

This study is the first of its kind in South Africa, and underlines the fact that tertiary students are particularly vulnerable when it comes to food security. Often a student has to juggle their studies with their role as breadwinner.

A tiny ray of hope to students who find themselves as food insecure, is the No Student Hungry Programme that offers a food bursary to qualifying students.

This programme, initially established by Prof Jonathan Jansen, UFS Vice-Chancellor and Rector, and now managed by Grace Jansen and Karen Buys, offers a small allowance of about R30 per day to hungry students with an average academic achievement of 60% and above. This criterion discourages entitlement thinking and builds a strong sense of responsibility on the part of those who benefit from the food bursary.

Melanie, a second-year Geography and Environmental Management student, as well as a single mother, is a beneficiary of the NSH Programme. “This bursary helps me to get a balanced meal every day. It is one less worry for me. I dream of completing my studies so that I can be independent and provide my son with the life he deserves.”
