Prof Abdon Atangana was recently elected a fellow of The World Academy of Sciences (TWAS).

Prof Abdon Atangana, Professor of Applied Mathematics in the Institute for Groundwater Studies at the University of the Free State (UFS), was recently elected a fellow of The World Academy of Sciences (TWAS).

He also received the World Academy of Sciences Award for Mathematics (TWAS -Mohammad A. Hamdan, 2020) on 1 November 2021.

TWAS, described as the voice for science in the South, is working towards the advancement of science in developing countries and supports sustainable prosperity through research, education, policy, and diplomacy. 

Outstanding contribution to science

Prof Mohamed HA Hassan, President of TWAS, congratulated Prof Atangana on this prestigious achievement, “Your election as fellow is a clear recognition of your outstanding contribution to science and its promotion in the developing world. We will be honoured to have you among our members.”

Candidates elected as TWAS Fellows are scientists whose contributions to their respective fields of science meet internationally accepted standards of excellence, and they must have distinguished themselves in efforts to promote science in developing countries. 

Prof Atangana is known for his research to develop a new fractional operator, the Atangana-Baleanu operator, which is to model real-world problems. With this operator, he not only describes the rate at which something will change, but also account for disrupting factors that will help to produce better projections.

Among others, his models can advise people drilling for water by predicting how groundwater is flowing in a complex geological formation. Furthermore, his work can also be applied to predict the spread of infectious diseases among people in a settlement, forecasting the number of people who will be infected each day, the number of people who will recover, and the number of people who will die. 

These are only two examples of how his work can be applied to better the lives of people.

Promoting science in the developing world

Besides promoting science in the developing world, Prof Atangana’s work also contributes to the United Nations Sustainable Development Goals – the global goals as set in 2015 that call for ending poverty, protecting the planet, and ensuring that all people enjoy prosperity and peace.

Prof Atangana says the election as fellow is a clear recognition of his outstanding contribution to science and its promotion in the developing world. “My work over the past five years has made a great impact in all fields of science, technology, and engineering.”

To be elected as TWAS fellow in mathematics, made him the second South African researcher to be elected in the field of mathematics (the first person elected was Prof Reddy Batmanathan Dayanand, who was elected in 2003). This also placed him as the sixth African mathematician to be elected as a TWAS fellow.

Very recently, he also ranked number one in the world in mathematics, number 186 in the world in all the fields, and number one in Africa in all the fields, according to the Stanford list of 2% single-year table.

He was also named among the top 1% of scientists on the global Clarivate Web of Science list. Less than 6 200 or 0,1% of the world's researchers were included on this list in 2020, with no more than 10 of the scientists hailing from South Africa. 

Prof Atangana is also editor of more than 20 top-tier journals of applied mathematics and mathematics, and for some of these journals he was the first African to be selected as editor.

Plant-strengthening agent enhances natural ability of plants to survive
2015-07-27

Drought, diseases, and fungi. These are factors that farmers have no control over, and they often have to watch despondently as their crops are damaged. In addition, the practice of breeding plants in special and strictly-controlled conditions, has resulted in crops losing the chemical ability to protect themselves in nature.

Researchers in the Department of Soil, Crop, and Climate Sciences at the University of the Free State (UFS) have developed an organic agent that restores this chemical imbalance in plants. It enables the plant to build its own resistance against mild stress factors, and thus ensures increased growth and yield by the plant.

ComCat®, a plant-strengthening agent, is the result of extensive research by the German company, Agraforum AG, together with the UFS. Commercialisation was initially limited to Europe, while research was done at the UFS.

“Plants have become weak because they were grown specially and in isolation. They can’t protect themselves any longer,” says Dr Elmarie van der Watt from the department.

Dr Van der Watt says that, in nature, plants communicate by means of natural chemicals as part of their resistance mechanisms towards various stress conditions. These chemicals enable them to protect themselves against stress conditions, such as diseases and fungi (biotic conditions) or wind and droughts (abiotic conditions).

Most wild plant varieties are usually well-adapted to resist these stress factors. However, monoculture crops have lost this ability to a large extent.

The European researchers extracted these self-protection chemicals from wild plants, and made them available to the UFS for research and development.

“This important survival mechanism became dormant in monoculture crops. ComCat® wakes the plant up and says ‘Hey, you should start protecting yourself’.”

Research over the last few years has shown that the agent, applied mostly as a foliar spray, subsequently leads to better seedlings, as well as to growth, and yields enhancement of various crops. This is good news for the agricultural sector as it does not induce unwanted early vegetative growth that could jeopardise the final yield ? as happened in the past for nitrogen application at an early growth stage.

“The use of synthetic agents, such as fungicides which contain copper, are now banned. Nowadays, options for natural and organic agriculture is being investigated. This product is already widely used in Europe, but because farmers are often swamped by quacks, the South African market is still somewhat sceptical.”
