Prof Abon Atangana — Prof Abdon Atangana, leading applied mathematics scholar at the University of the Free State, who has been awarded the Chevalier de l’Ordre de la Valeur by the President of Cameroon in recognition of his outstanding contributions to science and international academic engagement.

In recognition of his exceptional contributions to science and for promoting a positive image of Cameroon internationally, Prof Abdon Atangana, a leading professor of applied mathematics at the University of the Free State (UFS), has been awarded one of the country’s highest national honours by His Excellency President Paul Biya.

Prof Atangana, who is based in the UFS Faculty of Natural and Agricultural Sciences, was formally informed by the Cameroon High Commission in Pretoria that the President had decided to confer upon him the title Chevalier de l’Ordre de la Valeur (Knight of the Order of Valour).

“I am deeply honoured by this recognition and grateful to the High Commission for conveying the news,” said Prof Atangana.

The Ordre de la Valeur is one of Cameroon’s principal national distinctions, awarded to individuals who have rendered distinguished service or made significant contributions in fields such as science, public service, the arts, or international representation.

“The title Chevalier denotes formal national recognition by the President,” Prof Atangana explained. “It affirms the value of my work and encourages continued research, mentorship, and international collaboration.”

A career of global impact and recognition

Prof Atangana’s career is marked by both academic excellence and international engagement. He has consistently ranked among the top 1-2% of applied mathematicians worldwide, according to Stanford University’s global list. His achievements include being the first African mathematician under 40 to become a Fellow of the African Academy of Sciences Affiliates, receiving the UNESCO–TWAS Mohammad A. Hamdan Prize, the AL Fozan UNESCO Award for STEM, and the African Genius Award.

He also serves as Chair of the African Mathematical Union Commission on Research and Innovation and is the first President of the African Society for Industrial and Applied Mathematics (ASIAM).

In a historic milestone for African mathematics, Prof Atangana represented Africa for the first time at the Board Meeting of the International Council for Industrial and Applied Mathematics (ICIAM) in Vietnam in 2025. This prestigious gathering brings together presidents of national and international applied mathematics societies, including the President of the International Mathematical Union, and marks a significant recognition of his leadership on the global stage.

“Being named Chevalier de l’Ordre de la Valeur recognises years of sustained work and the support of many colleagues and students,” he said. “Professionally, it is an important encouragement to continue my research, mentoring, and international engagement.”

Beyond awards, Prof Atangana has actively promoted Cameroon’s profile in the international scientific community. He has built high-impact research collaborations, supervised and mentored students from Cameroon and across Africa, presented at international conferences, and published research connecting African science with global knowledge networks.

Advancing science through the UFS and international collaboration

Much of the work recognised by this honour has been conducted at the University of the Free State.

“The recognition reflects the outcomes of work done at the UFS and signals the university’s contribution to advancing regional research capacity and international partnership,” Prof Atangana said.

His academic engagement in South Africa has enabled him to act as a bridge between institutions, fostering joint research, student exchanges, and collaboration across continents. These activities demonstrate the power of academic engagement in promoting scientific excellence and strengthening international networks.

Looking ahead, Prof Atangana plans to leverage this recognition to expand collaborative research projects, create more opportunities for student exchanges and mentorship, and advance interdisciplinary initiatives addressing regional and global challenges.

“I will continue to promote the value of academic engagement in service of shared scientific and societal goals,” he said. “This recognition will inspire me to strengthen collaborative networks, pursue joint research initiatives, and mentor the next generation of researchers.”

Details of the official medal award ceremony will be shared by the Cameroon High Commission in due course.

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.
