The Centre for Environmental Management (CEM) at the University of the Free State (UFS), in collaboration with Dr Dirk Jungmann from the Technical University Dresden, recently presented a virtual summer school on Blackboard, titled: Monitoring of surface water quality: General framework, tools and implementing disaster management aspects in urban areas.

The international group of 30 persons who attended the summer school mostly comprised postgraduate students and employees from, among others, the UFS and other tertiary institutions such as the Technical University Dresden (TUD), the Cape Peninsula University of Technology (CPUT), UNISA, the University of the Western Cape, Stellenbosch University, the University of Lesotho, and the University of Zimbabwe. Members of the Council for Scientific and Industrial Research also attended the summer school.

Experts present

Dr Marinda Avenant, Senior Lecturer in the CEM, believes the summer school provides students with a wonderful opportunity to be exposed to a topic, such as aquatic biomonitoring, over and above their normal postgraduate studies. “The presenters are all experts in their field and come from a range of disciplines (from hydrology and chemistry to the social aspects of water), as well as from different countries and perspectives,” she adds.

Some interesting topics covered during the summer school included a panel discussion on water management challenges in Southern Africa. Head of CEM, Prof Paul Oberholser, participated in this live discourse. In 2021, he won the NSTF-Water Research Commission (WRC) Award for his contribution to water resource management in SA over the past five years.

Also contributing a perspective on surface water quality was affiliated professor in CEM, Prof Anthony Turton, who delivered the keynote address on Managing surface water quality as an element of disaster management in urban areas.

Dr Alice Ncube from the UFS Disaster Management Training and Education Centre (DiMTEC) presented on women and disasters (including a case study on a stokvel in Botshabelo), and Dr Inga Jacobs-Mata from the International Water Management Institute (IWMI) provided a social perspective on the water resources sector.

Students excel

Five master’s students representing the UFS, the Technical University Dresden (TUD), as well as the Cape Peninsula University of Technology (CPUT), assisted with the organisation of the summer school. The Volkswagen Foundation in Germany, which funded a first summer school in 2019, provided funding that was used to appoint the five students.

According to Dr Avenant, they made provision for the appointment of these students in their project proposal to the Volkswagen Foundation. “The students played a key role in the planning of the virtual summer school; they specially came up with ideas to make the virtual sessions more interesting,” she says.

Among others, they managed the technical aspects of the sessions, introduced the speakers, arranged social activities for the virtual platform, and they produced podcasts. The podcasts of the speakers were distributed to the participants over the extent of two months, in order to learn more about the presenters.

“We were really impressed with the work of the students, who are all from the natural sciences,” says Dr Avenant.

Different look for research in controlled circumstances at the UFS

Research in controlled circumstances at the University of the Free State (UFS) turned a new page today with the inauguration of four modernised controlled environment cabinets of the Department of Soil, Crop and Climate Sciences.

“The controlled environment cabinets, which are situated next to the glass houses on the eastern side of the Agriculture Building on the Main Campus in Bloemfontein, were installed in the early 1980’s. The cabinets, used for research purposes in controlled circumstances by the UFS for many years, became dysfunctional and needed to be repaired and put into use again,” said Prof Herman van Schalkwyk, Dean: Faculty of Natural and Agricultural Sciences at the UFS.

“The cabinets are used by the agronomics, horticulture and soil science divisions of the Department of Soil, Crop and Climate Sciences to control factors such as the temperature, the intensity and quality of light, synthesis and humidity. This is done 24 hours a day, with hourly intervals,” said Prof Van Schalkwyk.

The cabinets are ideally suited to determine the joint and separate effects of these factors on the growth of plants. The adaptability of plants to climate can also be investigated under controlled circumstances. All of this leads to a better understanding of the growth and development process of plants, more specifically that of agricultural crops.

“The effect of these environmental factors on the effectiveness of insect killers such as fungus killers, insecticide and weed killers can also be investigated and can help to explain the damage that is sometimes experienced, or even prevent the damage if the research is timeously,” said Prof Van Schalkwyk.

A new cabinet can cost between R2-3 million, depending on the degree of sophistication. “Although controlled environment cabinets have been used for agricultural research for a long time, it has become costly to maintain them and even more impossible to purchase new ones,” said Prof Van Schalkwyk.

According to Prof Van Schalkwyk the cabinets were re-built by die UFS Electronics and Mechanisation Division. Some of the mechanisms were also replaced and computerised.

“The re-building and mechanisation of the cabinets were funded by the faculty and because the work was done by our own staff, an amount of about R1 million was saved. The maintenance costs will now be lower as the cabinets are specifically tailor made for our research needs,” said Prof Van Schalkwyk.

Where all monitoring was done manually in the past, the cabinets can now be controlled with a computer. This programme was designed by Prof Koos Terblans from the UFS Department of Physics.

According to Prof Van Schalkwyk the modernisation of the cabinets is part of the faculty’s larger strategy to get its instruments and apparatus up to world standards. “With this project we have proved that we can find a solution for a problem ourselves and that there are ways to get old apparatus functional again,” said Prof Van Schalkwyk.
