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.”

Reclassification of giraffe status pivotal in public action, says UFS researcher

Great news for those who care about the conservation of giraffes is today’s (8 December 2016) announcement by the International Union for the Conservation of Nature (IUCN) that giraffes are now classified as ‘Vulnerable’. The species, formerly classified as ‘Least Concern’ on the IUCN Red List — an index on the likelihood of extinction of animals worldwide — is threatened with extinction.

“Until recently, few people were aware of the situation facing giraffes. It is time to show the world giraffe numbers are in danger. This reclassification by the IUCN is pivotal to get the public to stand up and take action for giraffes,” said Dr Francois Deacon, specialised researcher in the Department of Animal, Wildlife, and Grassland Sciences at the University of the Free State (UFS).

Research is essential to develop effective conservation plans for a species

Key to this announcement was the status report submitted by Dr Deacon. He was the lead author responsible for the submission of the Southern African Giraffe subspecies (Giraffa camelopardalis giraffa) status report that was part of the larger species report submitted for review by the (IUCN). The UFS has been doing many research projects in the past couple of years on giraffe-related issues and topics to address this problem.

The UFS is one of only a few universities in Africa that is committed to studying giraffes to ensure the conservation of this species for generations to come.

“The reclassification of giraffes to ‘Vulnerable’
status, by the IUCN, is pivotal to get the public
to stand up and take action for giraffes.”

A 40% decline in the giraffe population over the past two decades is proof that the longnecks are officially in trouble. According to Dr Deacon, this rate of decline is faster than that of the elephant or rhino. The main reasons for the devastating decline are habitat loss, civil unrest and illegal hunting.

Dr Deacon, pioneer in the use of GPS technology to study giraffes and their natural habitat, said “This vulnerability clearly stipulates we are quickly losing grip on our last few natural populations”. He and a team of researchers at the UFS in South Africa are leading various research and conservation projects to help save the last remaining giraffes in Africa.

Giraffes moved from ‘least concern’ to ‘vulnerable’ on the Red List

The IUCN, a health check for our planet, is the highest level at which decision-makers can prove how many species (fauna or flora) are surviving or not. The update from ‘Least Concern’ to ‘Vulnerable’ on the Red List was released at the 13th Conference of the Parties to the Convention on Biological Diversity in Cancun, Mexico.

A wildlife documentary, Last of the Longnecks clearly shows how the number of giraffes has plummeted in the past two decades from 154 000 to fewer than 98 000 today — with numbers of some giraffes, such as Kenya’s reticulated giraffe, declining by as much as 80%.  

Any individual or institution that wants to make a contribution relating to giraffe research can contact Dr Deacon at the UFS on deaconf@ufs.ac.za.
