The Department of Chemistry at the University of the Free State (UFS) held a successful online International Symposium on Organic Chemistry on 15 June 2021. The symposium brought together scientists from several South African and foreign universities and created a virtual platform for a long-awaited discussion stalled by the COVID-19 pandemic. About 20 participants from universities in South Africa, Belgium, and Germany presented their lectures during the symposium. In addition, this symposium was directed at the postgraduate students in the Department of Chemistry at the UFS, allowing them to present their results to an international audience and to foster their engagement in scientific research.

For more than a year, the COVID-19 pandemic has prevented the common personal communication avenues for the researchers: face-to-face (F2F) conferences, symposia, and workshops. To bridge this gap, Prof Vladimir Azov and Dr Charlene Marais from the Department of Chemistry organised the online meeting for the researchers from the UFS and several other local and foreign universities, all working in the field of organic chemistry.

Collaborative project between the UFS and VUB towards the development of gel-based drug release systems

The symposium also served as a long-awaited inception meeting for the collaborative project between the Organic Chemistry group at the UFS and the Organic Chemistry (ORGC) group at the Vrije Universiteit Brussel (VUB). This project is jointly funded by the National Research Foundation (NRF) and FWO (Research Foundation – Flanders); it is aimed at the development of new peptide-based materials with properties controllable by precisely tuned interactions of unnatural amino acids included in the peptide sequence. Such peptides can, for example, be used as smart materials for precisely controllable drug release. The South African team members, directed by Prof Vladimir Azov, will specialise in the development of the new amino acid building blocks, whereas the VUB team, headed by Prof Ulrich Hennecke, will focus on peptide preparation and studies on their properties.

This kick-off meeting was initially planned as a F2F event in June 2020 but was delayed due to the COVID-19 travelling restrictions and finally migrated to a virtual space. This provided an opportunity to present the project proposals and to discuss the initial results in a much broader circle than would have been possible within the common F2F meeting framework.

An interest in groundwater resource management ignited the spark for a PhD research thesis by Dr Yolanda Kotzé, Affiliated Researcher in the Institute for Groundwater Studies (IGS) at the University of the Free State (UFS).

Her PhD research thesis titled, A Framework for Groundwater Use Authorisations as Part of Groundwater Governance in Water Scarce Areas within South Africa, was the result of her interest in groundwater resource management. Dr Kotzé identified the agricultural sector as one of the major water users, and a decision was made to conduct research within this sector.  

Research funded by Institute for Groundwater Studies
Groundwater is water found underground in cracks and spaces in soil, sand, and rocks. It is stored in, and moves slowly through geological formations of soil, sand, and rocks (aquifers). The National Department of Water and Sanitation was indirectly the client for this research. The research project was funded by the IGS. Given the current drought, effective groundwater resource management can be achieved within all sectors through sustainable abstraction and use without over-abstraction.

“Groundwater can be effectively managed
in the agricultural sector by sustainable use,
monitoring the quantity of groundwater use,
and measuring groundwater levels,”
said Dr Kotzé.

Research addresses improvement of groundwater management
Her promotor, mentor, teacher, and friend, the late Prof Gerrit van Tonder, introduced her to the field of Geohydrology, and especially to groundwater resource management. “With my research, I made a significant contribution to the improvement of groundwater governance and groundwater resource management, as well as to the handling of groundwater use authorisations for irrigation purposes in South Africa,” said Dr Kotzé. With this significant contribution, she attempts to address the phenomenon of poor groundwater allocation and groundwater resource management by means of a framework. The development of this framework has shown the value of action research in an attempt to find a solution to a problem. “Groundwater can be effectively managed in the agricultural sector by sustainable use, monitoring the quantity of groundwater use, and measuring groundwater levels,” said Dr Kotzé.

The methodology of the research consisted primarily of action research, which has a five-phase cyclical process. The research was Dr Kotzé’s application for a PhD in Geohydrology at the UFS in 2012. The research was completed in 2015.
