Bridging Knowledge Cultures
A group of academics from the University of the Free State (UFS) and the North-West University (NWU) contributed to a chapter in the book Bridging Knowledge Cultures in Rural Health Education, which was recently launched during an online event.

The Directorate of Community Engagement at the University of the Free State (UFS) celebrated the publication of a chapter in the book, Bridging Knowledge Cultures. This transformative book was edited by Walter Lepore, Budd Hall, and Rajesh Tandon, Unesco co-chairs of the Unesco Chair in Community Based Research and Social Responsibility in Higher Education.

Chapter 10 of the book – ‘Bridging Knowledge Cultures in Rural Health Education’ – was contributed by a group of academics from the UFS and the North-West University (NWU). The UFS contributors included Dr Karen Venter, Head of Service-Learning in the Directorate of Community Engagement; Alfi Moolman, former coordinator in the same department; and Dr René Walter Botha, Coordinator for Community Based Education and Rural Health in the Faculty of Health Sciences. From the NWU, the contributors included Prof Lesley Wood, Extraordinary Professor in Community-Based Educational Research; Beatrix (Bibi) Bouwman, Director for Sustainability and Community Impact; and Prof Hendri Coetzee, Extraordinary Associate Professor in the North-West University’s COMPRES research unit.

Identify knowledge differences/gaps

According to Dr Venter, the study conducted in the Xhariep District was considered a unique context for an in-depth exploration of participants’ subjective experiences to identify knowledge differences/gaps, and recommendations to bridge them. She states, “The aim of the initiative was to improve health outcomes by establishing lifestyle groups to enable the sharing of health information among participants and thereby encourage sustainable, accountable lifestyle practices.” 

Three questions derived from the case study were discussed during the launch: Who has the right to create knowledge? Who decides if knowledge is valid? And who will have access to the knowledge?

Other case studies included in the book also explored the dynamics of equitable research partnerships, providing practical recommendations to overcome obstacles and forge effective collaboration between academia and diverse communities.

Embrace the richness of diverse perspectives

Dr Venter believes that the launch event inspired the next generation of researchers and professionals to embrace the richness of diverse perspectives and knowledge cultures.

To access the rest of the case studies, including those from Indonesia, Malaysia, and India, you can download the book here. Access the discussion on YouTube here.

Parallel to the book, a guide was launched: Bridging Knowledge Cultures: A Guide for Community Practitioners and Community Organisations. You can access a copy here.

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
