Qinisani Qwabe, one of the Mail & Guardian Top 200 Young South Africans, considers it important to always reach out and contribute to someone's life, no matter how small it may be.

Looking back at 2020, most people will not have fond memories. But for Qinisani Qwabe, a second-year PhD student in the Centre for Sustainable Agriculture, Rural Development and Extension, 2020 turned out to be a good year.

On 10 September, he heard that he was selected as one of the Mail & Guardian Top 200 Young South Africans in the education category. As if being elected as one of the prestigious group of young people is not enough, Qwabe added another feather in his cap when he was chosen as one of 21 young scientists by the Academy of Science of South Africa (ASSAf), in collaboration with the Department of Science and Innovation (DSI). 

When offered the chance to represent South Africa at a BRICS Conference in Russia, he seized the opportunity with both hands. At this virtual event, he presented a paper on a topic he cares about a lot – ecology. His paper, using a South African case study, was titled: The role of agrobiodiversity on environmental management and its impact on human ecology.

Sustainable resources

From an early age, growing up in a very isolated community called iSihuzu on the outskirts of Richards Bay, Qwabe worked hard. He not only reaped the rewards by seeing all his tuition fees paid, but he was also offered opportunities to make a difference in society. 

“I want to see a society that leads a sustainable life and values its natural resources. This is what wakes me up every morning. That is what I am working towards,” he says.

Qwabe has a registered organisation that, among others, seeks to achieve agricultural biodiversity, respect and value for local knowledge, sustainable development, as well as youth and community engagement.  

The organisation has two legs – one dealing with agricultural production and the other focusing on social entrepreneurship. “As part of this social entrepreneurship initiative, we are working with schools in the north of KwaZulu-Natal, where we do outreach programmes (e.g. donating school uniforms), and run projects driven towards sustainability,” says Qwabe.

But he believes that it is his voice on indigenous foods, together with his passion for research – complemented by community development initiatives – that contributed to his selection as one of Mail & Guardian’s top 200 Young South Africans. 

A greater vision

He is happy to be in the academia and believes that it will propel him towards his greater vision. 

“My vision for my future is to be well-known for my contributions on matters of environmental sustainability, and equally so, for community development. Parallel to my philanthropic undertakings, I envision being a leader in one of the leading organisations on environmental sustainability, such as the World Health Organisation's Food and Agricultural Organisation (FAO),” says Qwabe. 

Here he would like to focus his energies on food security, nutrition, and food safety; sustainable management and use of natural resources and forestry; and institutional capacity building for the sustained management of natural resources and increased agriculture production.

The next generation

Qwabe believes he is making an impact and building a solid foundation for the upcoming generations to build upon.  He urges the youth of South Africa to strive to make a difference. “No matter how small it might seem,” he says.

“To borrow from the American songwriter, Michael Jackson – WE are the world. And that 'WEness' denotes that each one of us has a role to play.

“This rating will motivate me to do more research, to improve outcomes, and to aim for a higher C-rating.” This was the response of Dr Jay le Roux, who was recently graded as an Y2-rated researcher by the National Research Foundation (NRF).

Dr Le Roux, senior lecturer in the Department of Geography at the University of the Free State (UFS), is one of 31 new NRF-rated researchers at the UFS. “This grading will make it possible to focus on more specific research during field research and to come in contact with other experts. Researchers are graded on their potential or contribution in their respective fields,” he said.

Research assess different techniques
His research on water erosion risk in South Africa (SA) is a methodological framework with three hierarchal levels presented. It was done in collaboration with the University of Pretoria (UP), Water Research Commission, Department of Agriculture, Forestry and Fisheries, and recently Rhodes University and the Department of Environmental Affairs. Dr Le Roux was registered for 5 years at UP, while working full-time for the Agricultural Research Council – Institute for Soil, Climate and Water (ARC-ISCW).

Water erosion risk assessment in South Africa: towards a methodological framework
, illustrates the most feasible erosion assessment techniques and input datasets that can be used to map water erosion features in SA. It also emphasises the simplicity required for application at a regional scale, with proper incorporation of the most important erosion-causal factors.

The main feature that distinguishes this approach from previous studies is the fact that this study interprets erosion features as individual sediment sources. Modelling the sediment yield contribution from gully erosion (also known as dongas) with emphasis on connectivity and sediment transport, can be considered as an important step towards the assessment of sediment produce at regional scale. 
 
Dams a pivotal element in river networks

Soil is an important, but limited natural resource in SA. Soil erosion not only involves loss of fertile topsoil and reduction of soil productivity, but is also coupled with serious off-site impacts related to increased mobilisation of sediment and delivery to rivers.

The siltation of dams is a big problem in SA, especially dams that are located in eroded catchment areas. Dr Le Roux recently developed a model to assess sediment yield contribution from gully erosion at a large catchment scale. “The Mzimvubu River Catchment is the only large river network in SA on record without a dam.” The flow and sediment yield in the catchment made it possible to estimate dam life expectancies on between 43 and 55 years for future dams in the area.
 
Future model to assess soil erosion
“I plan to finalise a soil erosion model that will determine the sediment yield of gully erosion on a bigger scale.” It will be useful to determine the lifespan of dams where gully erosion is a big problem. Two of his PhD students are currently working on project proposals to assess soil erosion with the help of remote sensing techniques.
