Dr Yong Sebastian Nyam aims to contribute to solutions to alleviate food insecurity, poverty and inequality, community resilience, and disaster preparedness on the continent.

With a PhD in hand and a recent appointment as an African fellow to the World Bank, the sky is the limit for Dr Yong Sebastian Nyam, an alumnus of the University of the Free State. 

Dr Nyam, who also completed an MSc in Agricultural Economics through the University of the Free State and was named the best master’s student in the Department of Agricultural Economics in 2018, joined the World Bank’s Urban, Disaster Risk Management, Resilience and Land Global Practice on 3 January 2022 for a six-month fellowship programme organised and managed by the Office of the Chief Economist, Africa Region (AFRCE). 

The programme equips African PhD candidates and recent graduates (less than three years) from different universities around the world with hands-on experience at the World Bank Group’s headquarters in Washington DC or its country offices.

Dr Nyam says: “Fellows will work on research, economic policy, technical assistance, and lending operations that contribute to the World Bank Group’s goal of eliminating poverty and increasing shared prosperity.”

During his time with the World Bank, Dr Nyam will be working on urban resilience projects, especially projects focused on urban food systems and disaster risk reduction.

Working with experts and policy makers across the continent, he says: “I am hoping to gain some hands-on industry experience while contributing to developing solutions to the continent’s most pressing problems, such as food insecurity, poverty and inequality, community resilience, and disaster preparedness.”

Through the fellowship programme, Dr Nyam hopes “to use this opportunity to become a useful tool for sustainable development in Africa and to advance mentorship programmes geared towards preparing and informing PhD candidates on different career options in the industry and how to transition from academia to the industry”.

Reaping benefits of hard work and determination

Looking back on his academic journey, Dr Nyam is grateful for his ‘determination and self-discipline’ traits that set him apart from his peers, despite the fact that he experienced ‘financial challenges’ at home.

“I was not the most intelligent student, but the most hardworking, and I have never let financial difficulties stop me.”

On obtaining his PhD degree, Dr Nyam says: “Like many people, I thought a PhD was very difficult and almost impossible to do. I think the impression people give about a PhD degree is wrong and it scares a lot of people away from doing it. I quickly realised after one year of my master’s research that it was possible to do a PhD.”

About his time with the UFS, Dr Nyam says: “Most of the things I know in my professional life I learned from the institution; the memories are all good. I am extremely grateful for all the lessons and maybe one day I will write a book about my journey at the UFS, because there are so many stories about my experiences as Resident Assistant at President Steyn Residence for five years and as Research Assistant for four years.”

Fracking in the Karoo has advantages and disadvantages

Fracking for shale gas in the Karoo was laid bare during a public lecture by Dr Danie Vermeulen, Director of the Institute for Groundwater Studies (IGS). He shared facts, figures and research with his audience. No “yes” or “no” vote was cast. The audience was left to decide for itself.

The exploitation of shale gas in the pristine Karoo has probably been one of the most debated issues in South Africa since 2011.
 
Dr Vermeulen’s lecture, “The shale gas story in the Karoo: both sides of the coin”, was the first in a series presented by the Faculty of Natural and Agricultural Science under the theme “Sustainability”. Dr Vermeulen is a trained geo-hydrologist and geologist. He has been involved in fracking in South Africa since the debate started. He went on a study tour to the USA in 2011 to learn more about fracking and he visited the USA to further his investigation in May 2012.
 
Some of the information he shared, includes:

- It is estimated that South Africa has the fifth-largest shale-gas reserves in the world, following on China, the USA, Argentina and Mexico.
- Flow-back water is stored in sealed tanks and not in flow-back dams.
- Fracturing will not contaminate the water in an area, as the drilling of the wells will go far deeper than the groundwater aquifers. Every well has four steel casings – one within the other – with the gaps between them sealed with cement.
- More than a million hydraulic fracturing simulations took place in the USA without compromising fresh groundwater. The surface activities can cause problems because that is where man-made and managerial operations could cause pollution.
- Water use for shale-gas exploration is lower than for other kinds of energy, but the fact that the Karoo is an arid region makes the use of groundwater a sensitive issue. Dr Vermeulen highlighted this aspect as his major concern regarding shale-gas exploration.
- The cost to develop is a quarter of the cost for an oil well in the Gulf of Mexico.
- Dolerite intrusions in the Karoo are an unresearched concern. Dolerite is unique to the South African situation. Dolerite intrusion temperatures exceed 900 °C.

He also addressed the shale-gas footprint, well decommissioning and site reclamation, radio activity in the shale and the low possibility of seismic events.
 
Dr Vermeulen said South Africa is a net importer of energy. About 90% of its power supply is coal-based. For continued economic growth, South Africa needs a stable energy supply. It is also forecast that energy demand in South Africa is growing faster than the average global demand.
 
Unknowns to be addressed in research and exploration are the gas reserves and gas needs of South Africa. Do we have enough water? What will be the visual and social impact? Who must do the exploration?
 
“Only exploration will give us these answers,” Dr Vermeulen said.
