Why Good Science Needs Better Communication | Ep. 148

Good science can change lives—but only if people can understand it, trust it and see why it matters. In Episode 148 of the Lucentlands Podcast, hosts Dewald Kirsten and Louise Brodie speak to Prof Marina Joubert, Associate Professor of Science Communication at the Centre for Research on Evaluation, Science and Technology (CREST) at Stellenbosch University. Recorded at the Hortgro Technical Symposium 2026, the conversation explores why effective science communication must be treated as an essential part of research rather than an afterthought. Prof Joubert explains that communicating science does not mean “dumbing it down”. It means removing unnecessary jargon, explaining complex ideas in everyday language and connecting scientific evidence to the concerns, experiences and decisions of real people. The discussion also examines the relationship between scientists, agricultural media, growers and the wider public. Prof Joubert argues that good communication should be a reciprocal process in which scientists share their knowledge but also listen to the people and communities affected by their research. Key topics discussed: •Why scientific research must be visible and relevant to society •How storytelling makes complex science easier to understand •The importance of trust in scientists and scientific institutions •Why scientists should communicate uncertainty openly •The difference between misinformation and deliberate disinformation •How to recognise exaggerated or unsupported scientific claims •Why growers should ask questions before investing in agricultural products •The role of agricultural journalists and communication professionals •How scientists can build communication into research proposals and budgets •The potential benefits of public engagement for research impact and funding •Why communication must involve listening as well as speaking •How scientists, growers and the media can work together more effectively The episode also considers the growing volume of questionable claims confronting farmers—particularly around crop protection products and other agricultural inputs. Prof Joubert encourages growers to investigate the evidence, ask critical questions and be cautious when products promise multiple benefits without credible research to support those claims. She also challenges scientists to move beyond journal articles and conference presentations. As she explains, good science is essential, but effective communication is what makes that science visible, relevant and capable of creating meaningful impact. For young people entering science, her message is equally clear: remain curious, be humble, listen to communities and be willing to invest in effective communication.
