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.

Plant eco-physiologist finds effective solutions for crop optimisation

In a time characterised by society facing increasing population growth, food crises, and extreme climatic conditions such as drought, it is essential for farmers to integrate science with their work practices in order to optimise crops.

Role of photosynthesis and plant sap data

By knowing how to use photosynthesis and plant sap data for determining plant health, fast and effective solutions could be established for the optimisation of crops. This technique, which could help farmers utilise every bit of usable land effectively, is the focus of Marguerite Westcott’s PhD study. She is a junior lecturer and plant eco-physiologist in die Department of Plant Sciences at the University of the Free State.

Westcott uses this technique in her studies to prove that a newly-developed bio-stimulant stimulates plants in order to metabolise water and other nutrients better, yielding increased crops as a result.

Agricultural and mining sectors benefit from research

The greatest part of these projects focuses on the agricultural sector. Westcott and a colleague, Dr Gert Marais, are researching the physiology of pecan and citrus trees in order to optimise the growth of these crops, thus minimising disease through biological methods. Field trials are being conducted in actively-producing orchards in the Hartswater and Patensie areas in conjunction with the South African Pecan Nut Producers Association (SAPPA) amongst others.
 
The principles that Westcott applies in her research are also used in combination with the bio-stimulant in other studies on disturbed soil, such as mine-dump material, for establishing plants in areas where they would not grow normally. This is an economical way for both the agricultural and mining sectors to improve nutrient absorption, stimulate growth, and contribute to the sustainable utilisation of the soil.

The bio-stimulant contributes to the immunity of the plants.
It was tested in these pecan nut orchards (Hartswater).

Soil rehabilitation key aspect in research projects

“One of two things is happening in my research projects. Either the soil is rehabilitated to bring about the optimal growth of a plant, or the plants are used to rehabilitate the soil,” says Westcott.

Data surveys for her PhD studies began in 2015. “This will be a long-term project in which seasonal data will be collected continuously. The first set of complete field data, together with pot trial data, will be completed after the current crop harvest,” says Westcott.
