Dr Marinkie Madiope, the Campus Principal of the University of the Free State (UFS) South Campus, recently received an award from Dr Justina Dugbazah, the Senior Programme Education and Social Development Coordinator of the African Union Panel on Emerging Technologies’ Calestus Juma Executive Dialogue (APET-CJED) programme

Dr Madiope was recognised for the work she is doing in Africa through the CJED. She collected the award during CJED’s 6th Dialogue, in the presence of more than 20 African member states. 

Fit-for-purpose policies and curricula

The focus of this event, which took place in Dakar, Senegal, was on effectively harnessing educational innovations and technologies for formal and non-formal teaching and learning in Africa.

During the dialogue, the UFS was also appreciated for its visibility and impact on the African continent and was recognised as a prospective partner and collaborator on different science, technology, engineering, and mathematics (STEM) projects, which will be discussed and confirmed later in May 2022.

Dr Madiope, the Vice-President of the Technical Working Group (TWG) of the CJED, also gave a presentation at the dialogue, speaking about the education policy implementation curriculum review in Africa. Speaking from a South African context, she highlighted the different education policies and shared her views on how the relevant role players on the continent can collaborate to ensure that policies and curricula are designed and developed fit for purpose. 

Some of the recommendations were to contextualise education, science, technology and innovation policies, and teaching methods to the African context, and have science subjects translated into local languages for easy understanding and interpretation. It was also recommended to incentivise STEM education as to encourage girl participation in STEM projects. 

In the discussion following the dialogue presentation, member states also recommended that the funding set aside for education be increased to 25% of countries’ national budget.

Supporting the development of scarce skills

With AUDA-NEPAD’s support for skills development programmes that promotes the occupational prospects of young Africans, Dr Madiope’s presentation, which highlighted some of the scarce skills on the continent, was welcomed. According to her, the Media, Information and Communication Technologies Sector Education and Training Authority (MICTSETA) has identified a number of scarce skills on the continent. These skills, aligning with the Fourth Industrial Revolution, include artificial intelligence, cybersecurity, cloud computing, data science, software development, internet of things, robotic processing automation, design thinking, and quality engineering. The university are planning to get involved in developing the skills of the youth on the African continent in terms of three-dimensional printing, drone manufacturing, and drone awareness.

• CJED is supported by APET, the African Union Development Agency, and the New Partnership for Africa’s Development (AUDA-NEPAD) strategic initiative. APET advises the African Union and member states on harnessing emerging technologies for economic development, and AUDA-NEPAD provides a platform to promote inter-country and inter-regional learning and knowledge exchange on science, innovation, and emerging technologies across Africa.

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.
