Ndumiso Mbuthuma is currently pursuing a PhD in Development Studies with a focus on floods and disasters.

Ndumiso Mbuthuma, a PhD student at the University of the Free State (UFS), was part of a team that won the Durban leg of the Students Reinventing Cities competition. “It was a beautiful experience and an opportunity to not only be a student again but to contribute to the greater good,” Mbuthuma said.

The Students Reinventing Cities competition is coordinated by C40, a global network of nearly 100 mayors of the world’s leading cities who are united in action to confront the climate crisis.

The Umgeni Interchange Team, which consisted of Mbuthuma, who is a student in the UFS Centre for Development Support, three students from the University of Cape Town, and one from an institution in France, participated in the Durban leg of the competition, which began in April 2023. 

After deliberations by C40 and city representatives, the team was informed on 13 July 2023 that they had been selected as the winners of the regional Durban competition.

The Students Reinventing Cities competition provides a platform for students and academics to work with cities around the world to formulate plans to combat climate change. This year the competition took place in 12 cities, including Barcelona, Durban, Rome, Melbourne, and Milan, among others. “The aim of the competition is to find ways in which we can begin to build cities that are climate change-friendly,” Mbuthuma said. 

The winning presentation

The Umgeni Interchange Team was allocated four hectares of land by the eThekwini municipality to come up with a development idea. The team members, who specialise in various fields, had to rely on each other to create a winning project. Their proposal entailed the development of a mixed-use, commercial, retail, and affordable-housing block. 

“We wanted to ensure affordable housing not just for the rich but even for those who aren’t,” Mbuthuma explained. His PhD, which focuses on floods and disasters, provided guidance on ensuring that the housing block was resistant to floods and other disasters. The proposal also suggested sustainable resource use, including the use of solar panels to generate energy in order to reduce the impact of loadshedding. 

Even though a victory in the competition is a great feeling, Mbuthuma is more appreciative of the opportunity to have been active in the battle for a more sustainable future. “To hear that policymakers are interested in hearing what I have to say is a big deal to me.”

Future endeavours

Although there has been a concerted effort globally to combat climate change, Mbuthuma believes that in countries such as South Africa there hasn’t been adequate discourse around how development will take place in a future defined by climate change and the resulting disasters expected. As such, he is committed to working towards normalising these conversations.

A new publication, Fractional Operators with Constant and Variable Order with Application to Geo-Hydrology, will be published later this year, on 1 November 2017. The author, Prof Abdon Atangana, from the Institute of Groundwater Studies at the University of the Free State, said the book proposes new techniques for groundwater remediation, including guidelines on how chemical companies can be positioned in any city to avoid groundwater pollution.

Focus of the book
Prof Atangana said researchers and practitioners interested in groundwater modelling and remediation from applied mathematical and geo-hydrology backgrounds, will benefit from reading this book.

According to Elsevier, the book provides a physical review of fractional operators, fractional variable order operators, and uncertain derivatives to groundwater flow and environmental remediation. It presents a formal set of mathematical equations for the description of groundwater flow and pollution problems using the concept of non-integer order derivative. Both advantages and disadvantages of models with fractional operators are discussed.

“Researchers and practitioners
interested in groundwater modelling
and remediation from applied
mathematician and geo-hydrology
backgrounds, will benefit from
reading this book.”

About the author
Prof Atangana specialises in applied mathematics, groundwater modelling, fractional calculus and their applications, methods for partial differential equations, methods for ordinary differential equations, iterations methods, asymptotic methods, perturbations methods, and numerical method for fractional differential equations, uncertainties analysis. He has participated in 18 international conferences, organised six special sections and symposiums in international conference in Europe, Africa, Asia and USA, and has been invited as plenary speaker in eight international conferences. He also serves as editor on 20 international journal of mathematics and applied mathematics and editor-in-chief of two international journals of applied mathematics.
