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.

In August 2017, the Boyden Observatory in Bloemfontein played a major role in obtaining optical observations of one of the biggest discoveries ever made in astrophysics: the detection of an electromagnetic counterpart to a gravitational wave event.
 
An article reporting on this discovery will appear in the prestigious science journal, Nature, in October 2017. Co-authors of the article, Dr Brian van Soelen and Hélène Szegedi, are from the Department of Physics at the University of the Free State (UFS). Both Dr Van Soelen and Szegedi are researching multi-wavelength astronomy.
 
Discovery is the beginning of a new epoch in astronomy
 
Dr van Soelen said: “These observations and this discovery are the beginning of a new epoch in astronomy. We are now able to not only undertake multi-wavelength observations over the whole electromagnetic spectrum (radio up to gamma-rays) but have now been able to observe the same source in both electromagnetic and gravitational waves.”
 
Until recently it was only possible to observe the universe using light obtained from astronomical sources. This all changed in February 2016 when LIGO (Laser Interferometer Gravitational-Wave Observatory) stated that for the first time they had detected gravitational waves on 14 September 2015 from the merger of two black holes. Since then, LIGO has announced the detection of two more such mergers. A fourth was just reported (27 September 2017), which was the first detected by both LIGO and Virgo. However, despite the huge amount of energy released in these processes, none of this is detectable as radiation in any part of the electromagnetic spectrum. Since the first LIGO detection astronomers have been searching for possible electromagnetic counterparts to gravitational wave detections. 
 
Large international collaboration of astronomers rushed to observe source
 
On 17 August 2017 LIGO and Virgo detected the first ever gravitational waves resulting from the merger of two neutron stars. Neutron star mergers produce massive explosions called kilonovae which will produce a specific electromagnetic signature. After the detection of the gravitational wave, telescopes around the world started searching for the optical counterpart, and it was discovered to be located in an elliptical galaxy, NGC4993, 130 million light years away. A large international collaboration of astronomers, including Dr Van Soelen and Szegedi, rushed to observe this source.
 
At the Boyden Observatory, Dr Van Soelen and Szegedi used the Boyden 1.5-m optical telescope to observe the source in the early evening, from 18 to 21 August. The observations obtained at Boyden Observatory, combined with observations from telescopes in Chile and Hawaii, confirmed that this was the first-ever detection of an electromagnetic counterpart to a gravitational wave event. Combined with the detection of gamma-rays with the Fermi-LAT telescope, this also confirms that neutron star mergers are responsible for short gamma-ray bursts.  
 
The results from these optical observations are reported in A kilonova as the electromagnetic counterpart to a gravitational-wave source published in Nature in October 2017.
 
“Our paper is one of a few that will be submitted by different groups that will report on this discovery, including a large LIGO-Virgo paper summarising all observations. The main results from our paper were obtained through the New Technology Telescope, the GROND system, and the Pan-STARRS system. The Boyden observations helped to obtain extra observations during the first 72 hours which showed that the light of the source decreased much quicker than was expected for supernova, classifying this source as a kilonova,” Dr Van Soelen said.
