Social media discussions have provided a lens on how people are dealing with and talking about COVID-19. This has given risk communication new insights into online audiences.

The lingering effects of the COVID-19 pandemic on society presented the experts at the University of the Free State (UFS) with an opportunity – to conduct a scientific study by analysing our social media data in order to assist government health communicators to reflect on their communication strategies and, in turn, gain new perspectives from the general social media user (public). 

The study – led by Herkulaas Combrink, a data and medical scientist in the UFS initiative for Digital Futures, and Prof. Katinka de Wet, medical sociologist in both the UFS initiative for Digital Futures and the Department of Sociology at the UFS – uses “real-time snapshots of online interactions as a means to augment more traditional methods of conducting research on a given topic; in this case, responses to COVID-19”, said Combrink. 

The findings and ongoing work of the research project were presented to the Parliamentary Portfolio Committee on Communications. “During this meeting, critical engagement took place around risk communication and areas where we can strengthen this research,” said Combrink. Several international influential risk communicators on the African continent were present. 

Digital science at the forefront 

The opportunity to pursue this study was the result of Herkulaas Combrink’s secondment to the Free State Department of Health (FSDOH), where he identified the need to develop additional analytics for the already existing processes in risk communication in order to assist various communication strategies linked to developments regarding COVID-19 infections.  

Combrink also said “because the analysis of social media data does not normally form part of the traditional toolbox of investigation for this type of work, this novel application serves as an addition to the already existing communication analytics”. This research project will strengthen the level of cooperation between the UFS, other institutions, and the FSDOH to “synergistically strengthen communication strategies in relation to COVID-19”. 

By looking at how new knowledge around COVID-19 is developing the method (of analysing social media data), is to stay abreast of trending and burning issues on open-source social media platforms. “It is important to conduct this work using well-defined scientific methodology to extract, explore, analyse, and report on the data,” Combrink says. 

Given the rapidity with which new knowledge around COVID-19 is developing all over the globe, this method lends itself to staying abreast of emergent and burning issues that are trending on open-source social media sites. 

Variety of stakeholders needed

The magnitude of the research study required the involvement of stakeholders from different institutions. “A variety of stakeholders from different institutions are needed not only to contextualise the data, but also to provide social and technical input to solve the problem,” Combrink said.  

Experts included in the project are Dr Vukosi Marivate from the Department of Computer Science at the University of Pretoria, Dr Ming-Han Mothloung from the Department of Community Health at the UFS and the FSDOH, and Dr Samuel Mokoena, Priscilla Monyobo, Mondli Mvambi, and Elke de Witt from the FSDOH. “Without this core team, the work would not have been contextually relevant,” Combrink said.

Professor triumphs at Water Research Commission (WRC) Symposium
2013-12-13

 
Prof Leon van Rensburg

The university’s advancement of research excellence recently found further embodiment in Prof Leon van Rensburg from the Department of Soil- and Crop- and Climate Sciences. His expertise in the water sector resulted in award-winning research.

Prof Van Rensburg received the award for Sustainable Development Solutions 2013 at the Water Research Commission (WRC) Symposium held at the CSIR in Pretoria. The symposium acknowledged local scientific solutions that have had a global impact. Prof Van Rensburg was recognised for his outstanding research guiding the management of salinity under irrigation at farm level in South Africa – ensuring food production. The paper that earned him this honour is entitled “Rainwater harvesting and conservation practices: challenges and opportunities for sustainable land and water use of ‘The Green Village’ in arid to semi-arid climate zones.”

The awards were linked to the WRC’s newly-adopted corporate planning tool named the ‘Knowledge Tree’, guiding the commission’s operations. The ‘Knowledge Tree’ functions as a yardstick with which the WRC measures its impact in essential areas. The presentation of these accolades underscored the importance of water science and water technology in improving the daily reality of people at grassroots level.

Prof Van Rensburg’s research goal is to enhance the efficiency of water usage of crop production systems in both the dryland and irrigation sectors. Part of his latest achievements include being editor for a special edition of the Irrigation and Drainage Journal (2012; vol 61) on rainwater harvesting.

Prof Chris du Preez, co-author of the winning paper, is an expert on soil quality, especially organic matter. He serves as the Head of the Department of Soil, Crop and Climate Sciences and has also acted as President of the Soil Science Society of South Africa. His current research focuses on agricultural land use and soil organic matter changes, soil fertility and fertilisation, and agriculture water quality and usage.
