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.

Research helps farmers save with irrigation

Her advice to farmers is that they should make sure they are aware of the total cost (investment and operating costs) of an irrigation system. In most cases the investment cost is low, but the operating cost over the lifetime of the system is high.

“It is very important to have a look at the total cost and to install the most economic system,” says Marcill Venter, lecturer at the University of the Free State (UFS), who has done research on the economic sustainability of water-pipe systems.

Irrigation systems important components for farming
This research comes at a time when many farmers are relying on their irrigation systems due to persistent drought and low rainfall during 2016. South Africa has also experienced an abnormal increase in electricity tariffs in recent years. Due to tariff increases which threaten the future profitability of irrigation producers, the Water Research Commission (WRC) has launched and financed a project on the sustainable management of irrigation farming systems. “I had the opportunity to work on the project as a researcher,” says Venter.

The heart of every irrigation system is the water pipes that bring life to crops and livestock, and this is what Venter’s research is about. “Water pipes are part of the whole design of irrigation systems. The design of the system impact certain factors which determine the investment and operating costs,” she says.

Mathematical system to help farmers
Venter and Professor Bennie Grové, also from the Department of Agricultural Economics at the UFS, designed the Soil Water Irrigation Planning and Energy Management (SWIP-E) programming model as part of the WRC’s project, as well as for her master’s degree. “The model determines irrigation pump hours through a daily groundwater budget, while also taking into account the time-of-use electricity tariff structure and change in kilowatt requirements arising from the main-line design,” says Venter. The model is a non-linear programming model programmed in General Algebraic Modeling System (GAMS).

Design of irrigation system important for sustainability
The main outcome of the study is that the time-of-use electricity tariff structure (Ruraflex) is always more profitable than the flat-rate structure (Landrate). The interaction between the management and design of a system is crucial, as it determines the investment and operating costs. Irrigation designers should take the investment and operating cost of a system into account during the design process. The standards set by the South African Irrigation Institute (SAII) should also be controlled and revised.

Water-pipe thickness plays major role in cost cuts
There is interaction between water-pipe thickness, investment and operating costs. When thinner water pipes are installed, it increases the friction in the system as well as the kilowatt usage. A high kilowatt increases the operating cost, but the use of thinner water pipes lowers the investment cost. Thicker water pipes therefore lower the friction and the kilowatt requirements, which leads to lower operating costs, but thicker pipes have a higher investment cost. “It is thus crucial to look at the total cost (operating and investment cost) when investing in a new system. Farmers should invest in the system with the lowest total cost,” says Venter.
