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).

UFS keeps the power on
2015-06-24

 

At a recent Emergency Power Indaba held on the Bloemfontein Campus, support structures at the university met to discuss the Business Continuity Intervention Plan to manage load shedding on the three campuses of the UFS.

Currently, 35 generators serving 55 of the buildings have already been installed as a back-up power supply on the three campuses of the university. According to Anton Calitz, Electrical Engineer at the UFS, the running cost to produce a kWh of electricity with a diesel generator amounts to approximately three times the cost at which the UFS buys electricity from Centlec.

Planned additional generators will attract in excess of R4 million in operating costs per year. For 2015, the UFS senior leadership approved R11 million, spread over the three campuses. Remaining requirements will be spread out over the next three years. University Estates is also looking at renewable energy sources.

On the Bloemfontein Campus, 26 generators serving forty-one buildings are in operation. On South Campus, two generators were installed at the new Education Building and at the ICT Server Room. Lecture halls, the Arena, the Administration Building, and the library will be added later in 2015. Eight generators serving 12 buildings are in operation on the Qwaqwa Campus. In 2015, the Humanities Building, Lecture Halls and the heat pump room will also be equipped with generators.

Most buildings will be supplied only with partial emergency power. In rare cases, entire buildings will be supplied because the cost of connecting is lower than re-wiring for partial demand. According to Nico Janse van Rensburg, Senior Director at University Estates, emergency power will be limited to lighting and power points only. No allowances will be made for air-conditioning.

“Most area lighting will also be connected to emergency power,” he said.

Where spare capacity is available on existing emergency power generators, requests received for additional connections will be added, where possible, within the guidelines. The following spaces will receive preference:
- Lecture halls with the lights, data projectors, and computers running
- Laboratories for practical academic work and sensitive research projects
- Academic research equipment that is sensitive to interruptions
- Buildings hosting regular events

According to Janse van Rensburg, all further needs will be investigated. Staff can forward all emergency power supply needs to Anton Calitz at calitzja@ufs.ac.za

Staff and students can also manage load shedding in the following ways:

1. Carry a small torch with you at all times, in case you are on a stairwell or other dark area when the lights go out. You can also use the flashlight app on your phone. Download it before any load shedding occurs. This can come in handy if the lights go out suddenly, and you cannot find a flashlight. Load-shedding after dark imposes even more pressure on our Campus Security staff. We can assist them with our vigilance and preparedness by carrying portable lights with us at all times and by assisting colleagues.
2. Candles pose a serious safety risk. Rather use battery- or solar-powered lights during load shedding.
3. Ensure that your vehicle always has fuel in the tank, because petrol stations cannot pump fuel during power outages.
4. Ensure that you have enough cash, because ATMs cannot operate without electricity.
5. The UFS Sasol Library has study venues available which students can use during load shedding.
6. When arranging events which are highly dependent on power supply, especially at night, organisers should consult the load-shedding schedule before determining dates and preferably also make back-up arrangements. If generators are a necessity, the financial impact should be taken into consideration.

The senior leadership also approved a list of buildings to be equipped with emergency power supplies.
