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.

“This rating will motivate me to do more research, to improve outcomes, and to aim for a higher C-rating.” This was the response of Dr Jay le Roux, who was recently graded as an Y2-rated researcher by the National Research Foundation (NRF).

Dr Le Roux, senior lecturer in the Department of Geography at the University of the Free State (UFS), is one of 31 new NRF-rated researchers at the UFS. “This grading will make it possible to focus on more specific research during field research and to come in contact with other experts. Researchers are graded on their potential or contribution in their respective fields,” he said.

Research assess different techniques
His research on water erosion risk in South Africa (SA) is a methodological framework with three hierarchal levels presented. It was done in collaboration with the University of Pretoria (UP), Water Research Commission, Department of Agriculture, Forestry and Fisheries, and recently Rhodes University and the Department of Environmental Affairs. Dr Le Roux was registered for 5 years at UP, while working full-time for the Agricultural Research Council – Institute for Soil, Climate and Water (ARC-ISCW).

Water erosion risk assessment in South Africa: towards a methodological framework
, illustrates the most feasible erosion assessment techniques and input datasets that can be used to map water erosion features in SA. It also emphasises the simplicity required for application at a regional scale, with proper incorporation of the most important erosion-causal factors.

The main feature that distinguishes this approach from previous studies is the fact that this study interprets erosion features as individual sediment sources. Modelling the sediment yield contribution from gully erosion (also known as dongas) with emphasis on connectivity and sediment transport, can be considered as an important step towards the assessment of sediment produce at regional scale. 
 
Dams a pivotal element in river networks

Soil is an important, but limited natural resource in SA. Soil erosion not only involves loss of fertile topsoil and reduction of soil productivity, but is also coupled with serious off-site impacts related to increased mobilisation of sediment and delivery to rivers.

The siltation of dams is a big problem in SA, especially dams that are located in eroded catchment areas. Dr Le Roux recently developed a model to assess sediment yield contribution from gully erosion at a large catchment scale. “The Mzimvubu River Catchment is the only large river network in SA on record without a dam.” The flow and sediment yield in the catchment made it possible to estimate dam life expectancies on between 43 and 55 years for future dams in the area.
 
Future model to assess soil erosion
“I plan to finalise a soil erosion model that will determine the sediment yield of gully erosion on a bigger scale.” It will be useful to determine the lifespan of dams where gully erosion is a big problem. Two of his PhD students are currently working on project proposals to assess soil erosion with the help of remote sensing techniques.
