Prof Abdon Antangana
Prof Abdon Atangana, a Professor of Applied Mathematics in the Institute for Groundwater Studies at the University of the Free State (UFS) and South Africa’s top-ranked scientist in Mathematics, wants to prepare the next generation of African professors.

A new book written by Prof Abdon Atangana, Professor of Applied Mathematics at the Institute for Groundwater Studies at the University of the Free State (UFS), in collaboration with one of his students, on the flow of groundwater, suggests several new and modified models to better predict anomalous behaviours of the flow and the movement of pollution within complex geological formations.

Mathematical Analysis of Groundwater Flow Models is one of two books Prof Atangana published recently that he wrote with his students. The other, Fractional Stochastic Differential Equations: Applications to Covid-19 Modeling, provides a thorough conversation on the underpinnings of COVID-19 spread modelling. He wrote the book with a postdoctoral fellow, Dr Seda Araz Igret from SIIRT University, Turkey. Since 2016 he has published a total number of six books, some of which are still under evaluation by Springer and Elsevier.

Time to prepare next generation of African professors 

This highly cited researcher is excited about collaborating with his students on projects such as these as he feels it is time for him to prepare the way for the next generation of African professors. Prof Atangana is ranked at No 219 in the world rankings and No 1 in South Africa by Research.com, a leading academic platform for researchers. 

According to the platform, which recently released the 2022 Edition of its Ranking of Top 1000 Scientists in the field of Mathematics, the ranking is based on the H-index metric provided by Microsoft Academic and includes only leading scientists with an H-index of at least 30 for academic publications in the field of Mathematics.

“Both books are important for me because they are first-time published books with my own students. There is a time to prepare the way for yourself and a time to prepare ways for the next generation. It is time for me to prepare the way for the next generation of African professors. I wish that the next time this list (https://research.com/scientists-rankings/mathematics/za) [is released] many of my students [will] appear,” says Prof Atangana.

About his book with Dr Igret, he says it presents the dynamic of COVID-19 spread behaviour worldwide. It is noticed that the spread dynamic followed process with nonlocal behaviours, which resemble power law, fading memory, crossover, and stochastic behaviours. Fractional stochastic differential equations are therefore used to model spread behaviours in different parts of the world. 

“The content coverage includes a brief history of COVID-19 spread worldwide from December 2019 to September 2021, followed by statistical analysis of collected data for infected, death and recovery classes,” says Prof Atangana.

Mathematical analysis of Groundwater Flow Models serves as a valuable resource for graduate and PhD students as well as researchers working within the field of groundwater modelling, says Prof Atangana. It includes features such as:
• Modified numerical and analytical methods for solving new and modified models for groundwater flow and transport 
• New flow and transform models for groundwater transport in complex geological formations 
• Examination of fractal and crossover behaviours and their mathematical formulations

Top-ranking scientist 

Prof Atangana was also recently elected as a fellow of The World Academy of Sciences (TWAS) and received the World Academy of Sciences Award for Mathematics (TWAS -Mohammad A Hamdan, 2020) on 1 November 2021.

Very recently, he was also ranked No 1 in the world in Mathematics, No 186 in the world in all the fields, and No 1 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. Fewer than 6 200 or 0.1% of the world’s researchers were included on this list in 2019, 2020 and 2021, with fewer than 10 of the scientists hailing from South Africa. 

“While my name is ranked No 1 in South Africa and No 219 in the world, this shows the impact of my research that has been done since 2013. It is worth noting that this ranking disadvantages younger researchers. For example, I got my first publication in 2013 but the researcher who was ranked No 1 started in 1972. To make the ranking fair, the total H-index should be divided by the number of years of publication. I am very proud to see that despite this disadvantage I am still topping in South Africa and am No 219 in the world.”

Inter-country adoptions can offer relief

Inter-country adoptions must not be taken lightly; however, in some instances it is suitable and can bring relief to a child. These were the words of Katinka Pieterse from Abba Adoptions, which specialises in inter-country adoptions.

She was one of the expert presenters at a recent workshop on inter-country adoptions that was recently presented by the Unit for Children’s rights in the Department of Criminal and Medical Law in the Faculty of Law at the University of the Free State (UFS).

Judge of Appeal Belinda van Heerden, an expert in the field of Child and Family Law, gave an overview as well as a Southern African perspective on this controversial topic. The Hague Convention sets international standards to protect children from the inherent dangers that accompany inter-country adoptions. The South African law must be aligned with these international standards by incorporating specific stipulations as well as the Hague Convention into legislation applicable to children. There must also be acted in the best interest of the child, said Judge van Heerden. The authorities have safety measures in place to protect children from these dangers. The starting point remains that inter-country adoptions are only considered once one cannot find suitable care in the country of origin.

Prof. Sheryl Buske from the Charlotte School of Law, North Carolina in the United States of America in particular emphasised the dangers of human trafficking that can take place when inter-country adoptions do not adhere to international safety standards. She also pointed out new developments such as the role of surrogate mothers and the adoption of embryos.

The workshop was attended by a large variety of role players, varying from academics, lawyers, social workers, non-governmental organisations, law students and representatives from governmental institutions. Consequently, light was shed on the topic from a number of angles which will be of value to the respective role players. Jurists from Lesotho also expressed their gratitude for the insight they received.

The workshop was of great value to the university because it served the community with expert presentations on this new and sensitive topic. The guidelines and pitfalls that were discussed and pointed out at the workshop cleared uncertainties and brought new insight to the different professions and role players in the field. Furthermore, the bond between the academia and practice were developed and strengthened by the establishment of further cooperation between the parties.
