Dr Hlami Ngwenya believes that the UFS has a key role to play in Africa.

Dr Hlami Ngwenya, Lecturer in the Department of Sustainable Food Systems and Development at the University of the Free State (UFS), describes herself as a social scientist and global citizen – having worked in more than 50 countries, with more than 30 years of experience. 

She is equipping students to make a difference in their communities, whether it is here in South Africa, or in other countries in Africa where they reside and beyond. Dr Ngwenya joined the UFS in 2015, teaching the Advanced Diploma on Extension for Sustainability and the Master’s Programme on Sustainable Agriculture and Extension: Theory and Practice. 

Investing in farmers’ human capital globally

She has made major contributions to the field with her research work. In 2020, she contributed a chapter on ‘Food and Agriculture’ in the United Nations Development Programme (UNDP) report on COVID-19 Rapid Emergency Needs Assessment for the most vulnerable groups. In addition, she was part of a global study titled, Investing in farmers: Agriculture Human Capital Investment (AHCI) strategies, conducted in partnership with the International Food Policy Research Institute (IFPRI) and the Food and Agriculture Organisation (FAO Investment Centre).  

The latter study was conducted in nine countries in Africa, Asia, and Latin America. The aim was to improve the understanding of AHCI. The study also provides lessons learned from successful AHCI models around the world, with recommendations and guidelines for future investment that enhances the human capital of agricultural producers.

This year, she is working on a research paper titled, Demystifying facilitation of systemic change and the role of agriculture extension towards sustainable development and resilient food systems: analytical, conceptual and theoretical underpinnings.

Her input is also valued by paramount bodies in the industry, such as the Global Forum for Rural Advisory Services (GFRAS). Dr Ngwenya is a member of the GFRAS Consortium for Education and Training, and she is playing a significant role in terms of agricultural extension and advisory services at a global level. 

Global tool with local relevance 

She is also one of the faces behind the globally developed New Extensionist Learning Kit. Commonly known as NELK, this GFRAS product was created as a tool to augment and equip agricultural extension personnel with the functional skills relevant to managing the complexities of agricultural innovation and food systems. 

The UFS Department of Sustainable Food Systems and Development is one of the leading institutions globally that has adopted and adapted NELK as part of its curriculum. The South African Society for Agricultural Extension (SASAE) has also adopted the kit to contribute towards the continuous professional development of extension personnel. 

On the African continent, Dr Ngwenya has been a resource person for the African Forum for Agricultural Advisory Services (AFAAS) and supported the development of agricultural extension and advisory services fora at regional and national levels. 

Here on home soil, she continues to be involved with SASAE, supporting them in facilitating their strategic planning processes and professionalisation activities.

Spreading her wings beyond extension 

Beyond her active involvement in the agricultural extension field, Dr Ngwenya is a role player in other areas of agriculture globally. This includes agricultural policy, agricultural research, as well as agricultural education.  She brings all this knowledge and skills to benefit her students and the university. 

In her lifetime, she has had the opportunity to moderate more than 300 multi-stakeholder engagements, including strategic planning sessions, organisational development, team building, training, and conferences. These include high-level policy dialogues at United Nations level, the African Union Commission, and other continental and regional level organisations. 

Humbleness is empowering 

Although she had the chance to travel the world and engage at the highest level, she believes that it is important to be humble. She makes an effort to respect and cherish people for who they are, their cultures, and different systems. 

“One of the most valuable lessons I have learnt through engaging in many African countries, is that there is not necessarily co-relation between a country’s strong economy and human capital.” Despite the socio-political challenges that many countries go through (including ours), there are many genuine, hard-working, and intelligent people out there,” she says.

State-of-the-art physics equipment and investment in students result in academic success

Nanoscience, which is revealing new properties of very small arrangements of atoms, called nanoparticles, is opening a new world of possibilities. The Department of Physics at the University of the Free State is undertaking fundamental research with potential commercial applications. Its equipment and expertise is giving solid state physics research the edge in South Africa.

The UFS team of researchers and students are passionate about studying planets and atoms, all under one roof. Recently, the department, in collaboration with the South African Agency for Science and Technology Advancement (SAASTA), hosted a nanotechnology facility tour to give the public, learners and the media the opportunity to familiarise themselves with the science of nanotechnology, its origins, potential applications and risks.

Successes of the department
According to Prof Hendrik Swart, Senior Professor in the Department of Physics, the increase in resources since 2008 is playing a big role in the success rate of its research outputs. The Sarchi Chair awarded to Prof Swart in 2012 (bringing with it funding for equipment and bursaries) also contributed to the successes in the department.

The UFS Directorate Research Development also availed funding that was used for bursaries. These bursaries made it possible for the department to appoint 10 post-doctoral fellows, not one of them originally from South Africa.

The investment in people and equipment resulted in researchers and students publishing some 80 articles in 2016. Their work was also cited more than 900 times by other researchers in that year.

Another highlight in terms of the department’s growth in the past 10 years is the new wing of the Physics Building. Physics at the UFS is the only place in sub-Saharan Africa where state-of-the art equipment is found under one roof.

Application of research
The department is a unique research facility with equipment that includes the X-ray Photoelectron Spectrometer (for the study of atoms), the Scanning Auger Microscope, as well as the Ion Time-of-Flight Secondary Ion Mass Spectrometer (revealing the chemical bonds in a sample, and drawing maps of the positions of atoms).

One of the areas on which the department is focusing its research, is phosphors. Researchers are exploring light emitting diodes (LEDs) which use less energy, are brighter and provide a wider viewing field. They are also looking into LED displays (LCDs) which are used in flat screens – the phosphors create the different colours and backlighting.

The research on solar cells reveals that phosphors can increase their efficiency by increasing the range of light frequencies which can be converted into electricity. Glow-in-the-dark coatings absorb light in the day and emit it later so cells can charge at night. As glow-in-the-dark phosphors become cheaper and more effective, they can be used as a lighting substitute on the walls of houses, street numbers and stop signs.
