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).

The solution to student food insecurity is a holistic approach

Research at the University of the Free State (UFS) has indicated that nearly 60% of students are victims of food insecurity and suffer from hunger most of the time. The research by the UFS Faculty of Health Sciences shows that a further 25% are food insecure but are not hungry most of the time.

Senior Lecturer in the Department of Nutrition and Dietetics, Dr Louise van den Berg, says food insecurity is common among student populations across the world. However, local research shows that it is almost double that of tertiary institutions in developed countries.

Food insecurity among students caught many people off-guard
Dr Van den Berg says in South Africa nobody had really looked at the problem until recently “It seems student food insecurity has caught many people off-guard.” She says people tend to think of tertiary students as a privileged group.

The research has now indicated how deep the problem really is on campus. The students that most likely go hungry are single, male, black or coloured, and are generally first-generation students.

They are also mostly undergraduates, those paying their studies from non-bank loans or bursary means, those not living with their parents or guardians or those that need to support somebody else financially.

The results further indicate that those that are likely to suffer from hunger seldom or never have enough money for food but have to borrow money for food, have to ask for food, sell items to get food or steal food.

“A healthy student is a
successful student.”

Bursary money send back home for parents to survive
Dr Van den Berg agrees that one of the main reasons for the situation is economic stress. Research has shown students rarely spend money on food when resources are scarce. Furthermore, parents of students studying with bursaries are not always able to fully support them on campus. Some students send bursary money back home for their parents to survive.

She says other factors that contribute to campus food insecurity are that all over the world universities have terminated catered food halls due to high costs. “To a large extent this has created a food desert for students and now they need to look after themselves.”

To throw money at the problem does not seem to be the answer. 

Students are food-uncertain beings
The research indicates that young people on campus do not know where to buy food, much less the correct, nutritional food they need. Dr Van den Berg says most universities are now aware of the problem and have been taking steps. This includes teaching students how to budget and making them aware how important nutrition is for their success and their responsibility for themselves.

Universities are also looking at private funding for food aid and food schemes. Dr Van den Berg says other solutions are the restructuring of bursary fees, student self-help initiatives and food gardens.

The Faculty of Health Sciences is taking the initiative to manage a food blog on the UFS website. It will also use other social media platforms to post food-preparation videos and recipes for students.

Dr Van den Berg says it is important to grow the 15.6% group of students who indicated they are food secure because a healthy student is a successful student.
