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.

Research on locomotion of giraffes valuable for conservation of this species

The meaning of the Arab term Giraffe Camelopardalis is ‘someone who walks fast’. It is precisely this locomotion of their longnecks that encouraged researchers, Dr Francois Deacon and Dr Chris Basu, to study the animals more closely.

Despite the fact that giraffes are such well-known animals, very little research has been done on the manner in which these graceful animals locomote from one place to the next. There are only two known ways of locomotion: the slower lateral walking and the faster galloping. Most animals use these ways of moving forward. It is unknown why giraffes avoid intermediate-speed trotting.

Research of great value to the industry

Research on the manner in which giraffes locomote from one place to the next will assist the industry in understanding aspects such as their anatomy and function, as well as the energy they utilise in locomoting from one place to another. Information on the latter could help researchers understand where giraffes fit into the ecosystem. This data is of great value for large-scale conservation efforts.

Universities working together to collect data

Dr Basu, a veterinarian at the Royal Veterinary College in the UK, has studied the animals at a zoo park in the United Kingdom. He visited the University of the Free State (UFS) in order to expand his fieldwork on the locomotion of giraffes. This study was done in cooperation with Dr Deacon from the Department of Animal, Wildlife, and Grassland Sciences at the UFS. Dr Deacon is a specialist in giraffe habitat-related research in South Africa and other African countries.

The fieldwork for the research, which was done in the Woodland Hills Wildlife Estate and the Willem Pretorius Nature Reserve, preceded research on the movement and the forces involved in the locomotion of giraffes. Due to the confined fenced area in the zoo park, it was practically impossible to study the animals at speed. “The study of actions ‘faster than walking’ is crucial for gathering data on, inter alia, the frequency, length, and time associated with each step.


Technology such as drones offers unique
opportunities to study animals like giraffes.



Technology used to ensure accuracyTechnology such as drones offers unique opportunities to study animals like giraffes. Apart from the fact that it is possible to get high-quality video material of giraffes – moving at speed – it is also a very controlled device that ensures the accuracy of data.

It is the first time ever that a study has been done on the locomotion of giraffes with this level of detail.
Research on the study will be published in the Journal of Experimental Biology.

The project was approved by the UFS ethics committee.
