Five of the multidisciplinary team of researchers and some postgraduate students are determining the depth of soil on the underlying rock layer of the sodic site in the Kruger National Park.

When the Vice-Rector: Research, Prof Corli Witthuhn, invited researchers to apply for funding towards multidisciplinary and interdepartmental projects in 2015, Prof Piet le Roux from the Institute for Groundwater Studies, and the late Dr Fred Kruger from the Centre for Environmental Management took the opportunity and proposed a project to study a catenal ecosystem in the Kruger National Park

According to Dr Beanélri Janecke from the Department of Animal, Wildlife and Grassland Sciences, who led the research team on this project, the team of researchers worked for four years, finding links between the catenal ecosystem (which can be described as a hillslope with different zones forming an environmental gradient from crest to foothill) and processes behind some of its abiotic (non-living) and biotic (living) components. 

Large-scale multidisciplinary research project

All their research on this multidisciplinary project was published in one Special Issue of the Koedoe journal at the end of October 2020. Dr Janecke and Prof Johan van Tol from the Department of Soil, Crop and Climate Sciences were guest editors of this special issue. Dr Llewellyn Foxcroft from SANParks is the Editor-in-Chief of the journal. Other UFS departments involved in this project include the Departments of Genetics; Microbial, Biochemical and Food Biotechnology; Plant Sciences; and Zoology and Entomology.

Dr Janecke says there are 12 articles in this issue and, together with the principal researchers (but excluding postgraduate students), there were 12 authors from the UFS (eight departments and divisions in the Faculty of Natural and Agricultural Sciences) and two from SANParks in associated research collaboration with authors from 14 other institutions. 

This special issue of the Koedoe journal covered research on hydrology, flowpaths, and ground water, including the soil types and properties of different zones on the catena. As stated by Dr Janecke, there are also articles on micro-organisms, fungi, and Fusarium in the soil of the root zone of plants (rhizobiome). 

The environment is degrading fast due to human activities, and there is a dire need for research to look at the bigger picture to find solutions on how to conserve ecosystems and not only smaller parts thereof. – Dr Beanélri Janecke

The journal also comprised articles on the vegetation communities and vegetation structure in the different zones. “Research on how the vegetation recovered post-drought of 2016-2017 and on large and small mammals present on the catena and at the closest waterholes was also published. All of these topics were linked in a discussion article on the catenal ecosystem,” says Dr Janecke.

Multidisciplinary research is not conducted very often on this scale. Many researchers will rather focus on one or a few specific aspects of the ecosystem in a specialist research field. 

SANParks introduced supersite concept

Dr Janecke says scientists from SANParks initiated this supersite concept, where research can be focused on specific areas with similar geology and landscapes in the Kruger National Park to generate multidisciplinary data from separate specialist research fields. 

“Our project went one step further and combined different research fields into one project done on a supersite over the same period. This multidisciplinary project created the opportunity for specialist research fields to be published separately in one special issue, but also to combine the expertise in one project that was summarised in a discussion article.”

She believes that the environment is degrading fast due to human activities, and that there is a dire need for research to look at the bigger picture to find solutions on how to conserve ecosystems and not only smaller parts thereof. “There is a need for a more holistic approach to research, and this special issue provides a framework and basis for similar multidisciplinary studies in future,” states Dr Janecke.

This issue is currently widely marketed on all social platforms of the Koedoe journal and AOSIS Publishers, while a podcast interview is also available at:  https://soundcloud.com/aosis-za/koedoe-interview-podcast-2020 (with permission from Louw Lombaard from AOSIS).

New security measures for Rag fundraising
2012-01-25

The University of the Free State will no longer allow first-year students to sell Ritsems or to shake their cans for change at traffic robots in Bloemfontein in an effort to raise funds for Rag Community Service.

This decision follows after an evaluation has been done in 2011 and 2012 concerning the safety risk for students during this type of sales at road crossings.
 
The new security measures have specifically been implemented for this type of sales since last year.
 
The measures included, among others, that students should be obliged to wear brightly coloured safety jackets during sales, continuous supervision of first-year students by senior students to ensure that students keep to the rules of the road, and limiting the sales hours at robots.
 
Through notices in the media, an appeal was made on motorists to keep a lookout for students raising money for Rag Community Service. The measures were implemented and the effects thereof for students’ safety during sales at robots monitored since last year. This follows after a student, Ms Hanje Pistorius, was hit by a reckless driver in 2010 and she subsequently lost her leg as a result of the accident. 
 
Although, from all appearances, the new measures are a positive contribution to protect students even more, the UFS decided to abolish the sales and fund-raising actions at traffic robots. As reckless drivers would not necessarily take notice of the extra measures, the risk to students at robots stay unchanged. 
 
"The UFS sets the safety of its students as first priority and considers it in the best interest of students to not expose first-years to the risk during our Rag programme,” says Mr Rudi Buys, Dean: Student Affairs at the UFS.
 
Night fund-raising and the selling of Ritsem in the city’s suburbs will, however, continue. 
 
Although the UFS do not expect the new measures to be detrimental to fund-raising efforts, Rag Community Service currently considers new supporting proposals for the raising of funds for community projects in order to address any possible reduction in funds. 
 
Mr Buys also has an agreement with Ms Pistorius to assist Rag Community Services in the planning of new projects.
 
The Night fund-raising in suburbs will take place on Tuesday 24 January and Thursday 26 January and the UFS calls on residents to assist students and help them in the important task at hand.
 
Three Rag processions will take place on Saturday 28 January 2012. At 10:00 two Rag procession will be leave for Heidedal and Mangaung, where the Kovsie Rag Community Service will hand out food parcels.
 
The main Rag Procession will leave the UFS at 18:00 and will move towards the Old Greys sports ground for the Rag concert with Die Heuwels Fantasties and DJ Black Coffee.
