South Africa recently witnessed a catastrophic natural disaster that resulted in the loss of life, livelihoods, and infrastructural damage. This occurred in KwaZulu-Natal where hundreds of people lost their lives as a result of extensive flooding and mudslides. President Cyril Ramaphosa declared a national state of disaster to which we should all respond. Specific reference was made to the public and private sectors, as well as civil society.

While I applaud the various stakeholders that have extended a helping hand, my heart bleeds for the vulnerable groups whose voices remain unheard, even under normal circumstances. One cannot help but wonder if aid will reach the isolated regions that suffered the adverse effects of these heavy rains, or if all developmental efforts will be prioritised to certain economic hubs of the province such as the eThekwini Metro and the capital, uMgungundlovu.

KwaZulu-Natal is among the poorest provinces in the country. Corroborating this claim is a report that was released by Statistics South Africa earlier this year which reveals that about 52% of the province’s population are considered to be ‘poor’,and live at the lower end of the poverty line.

Drawing from my experiences of the rural communities of KwaZulu-Natal with whom I have worked, many suffer from the triple challenge of poverty, inequality, and unemployment, and rely on agriculture for their livelihood and to put food on the table. Their supplementary income is obtained from government support grants. The graphic scenes that have been shown on the media illustrate the devastating effects of the heavy rains in regions within the agricultural sector. Fields have been washed away, crops and livestock have been lost. This is happening when the province is still trying to resuscitate its economy after the widespread looting that took place in July last year, which had a calamitous effect on businesses and livelihoods.

While this is an injury mainly for the people of KwaZulu-Natal, it is my wish that we all join hands in contributing towards the restoration of livelihoods. In agreement with the president’s assertion, we can all play a part in rebuilding the province. This includes institutions of higher learning, particularly the Community Engagement Directorates whose mandate is to drive socioeconomic development to external communities.

Dr Abdon Atangana cements his research globally by solving fractional calculus problem
2014-12-03

 

Dr Abdon Atangana

To publish 29 papers in respected international journals – and all of that in one year – is no mean feat. Postdoctoral researcher Abdon Atangana at the Institute for Groundwater Studies at the University of the Free State (UFS) reached this mark by October 2014, shortly before his 29th birthday.

His latest paper, ‘Modelling the Advancement of the Impurities and the Melted Oxygen concentration within the Scope of Fractional Calculus’, has been accepted for publication by the International Journal of Non-Linear Mechanics.

In previously-published research he solved a problem in the field of fractional calculus by introducing a fractional derivative called ‘Beta-derivative’ and its anti-derivative called ‘Atangana-Beta integral’, thereby cementing his research in this field.

Dr Atangana, originally from Cameroon, received his PhD in Geohydrology at the UFS in 2013. His research interests include:
• the theory of fractional calculus;
• modelling real world problems with fractional order derivatives;
• applications of fractional calculus;
• analytical methods for partial differential equations;
• analytical methods for ordinary differential equations;
• numerical methods for partial and ordinary differential equations; and
• iterative methods and uncertainties modelling.

Dr Atangana says that, “Applied mathematics can be regarded as the bridge between theory and practice. The use of mathematical tools for solving real world problems is as old as creation itself. As written in the book Genesis ‘And God saw the light, that it was good; and divided the light from the darkness’, the word division appears here as the well-known method of separation of variables, this method is usually employed to solve a class of linear partial differential equations”.

“A mathematical model is a depiction of a system using mathematical concepts and language. The procedure of developing a mathematical model is termed mathematical modelling. Mathematical models are used not only in natural sciences, but also in social sciences such as economics, psychology, sociology and political sciences. These models help to explain systems and to study the effects of different components, and to make predictions about behaviours.”
