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.

Fracking in the Karoo has advantages and disadvantages

Fracking for shale gas in the Karoo was laid bare during a public lecture by Dr Danie Vermeulen, Director of the Institute for Groundwater Studies (IGS). He shared facts, figures and research with his audience. No “yes” or “no” vote was cast. The audience was left to decide for itself.

The exploitation of shale gas in the pristine Karoo has probably been one of the most debated issues in South Africa since 2011.
 
Dr Vermeulen’s lecture, “The shale gas story in the Karoo: both sides of the coin”, was the first in a series presented by the Faculty of Natural and Agricultural Science under the theme “Sustainability”. Dr Vermeulen is a trained geo-hydrologist and geologist. He has been involved in fracking in South Africa since the debate started. He went on a study tour to the USA in 2011 to learn more about fracking and he visited the USA to further his investigation in May 2012.
 
Some of the information he shared, includes:

- It is estimated that South Africa has the fifth-largest shale-gas reserves in the world, following on China, the USA, Argentina and Mexico.
- Flow-back water is stored in sealed tanks and not in flow-back dams.
- Fracturing will not contaminate the water in an area, as the drilling of the wells will go far deeper than the groundwater aquifers. Every well has four steel casings – one within the other – with the gaps between them sealed with cement.
- More than a million hydraulic fracturing simulations took place in the USA without compromising fresh groundwater. The surface activities can cause problems because that is where man-made and managerial operations could cause pollution.
- Water use for shale-gas exploration is lower than for other kinds of energy, but the fact that the Karoo is an arid region makes the use of groundwater a sensitive issue. Dr Vermeulen highlighted this aspect as his major concern regarding shale-gas exploration.
- The cost to develop is a quarter of the cost for an oil well in the Gulf of Mexico.
- Dolerite intrusions in the Karoo are an unresearched concern. Dolerite is unique to the South African situation. Dolerite intrusion temperatures exceed 900 °C.

He also addressed the shale-gas footprint, well decommissioning and site reclamation, radio activity in the shale and the low possibility of seismic events.
 
Dr Vermeulen said South Africa is a net importer of energy. About 90% of its power supply is coal-based. For continued economic growth, South Africa needs a stable energy supply. It is also forecast that energy demand in South Africa is growing faster than the average global demand.
 
Unknowns to be addressed in research and exploration are the gas reserves and gas needs of South Africa. Do we have enough water? What will be the visual and social impact? Who must do the exploration?
 
“Only exploration will give us these answers,” Dr Vermeulen said.
