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.

Researcher wins prize for her work to reduce environmental pollution

Josepha Zielke, a PhD student at the Institute for Groundwater Studies at the University of the Free State (UFS), received the prize for the best student presentation at the International Mine Water Association (IMWA) symposium in Leipzig, Germany, this year. Her paper was titled Fine Ash Leaching in Tailings Dams – An Impact on the Underlying Aquifers?
 
Zielke said: “It is an honour to receive this prize as a student. IMWA is a big association which allows you to establish a network with other scientists, to exchange opinions and ideas and to gain new inspiration for your own work. It was exciting and informative to hear about the research conducted around the world and to meet the researchers themselves.”
 
Born in Germany, Zielke always wanted to study overseas. During an exchange year in Grade 11, she visited South Africa. When she had to make a decision about in which country to complete her studies, South Africa was first choice as she was familiar with the people and the country.
 
Zielke joins leading institute on groundwater research in the country
She completed her BSc Hons in Geology at the Nelson Mandela Metropolitan University. After working for a year in exploration, she decided to focus her studies on water-related problems which  has been a growing issue, not only in South Africa, but in many places around the world. Zielke heard that the UFS Institute for Groundwater Studies was the leading institute on groundwater research in the country, and decided to join the university.
 
After completing her MSc research, An analysis of the geochemical weathering profile within a fine ash tailings dam, Mpumalanga, South Africa, Zielke started the research for her PhD project on groundwater pollution along a fault system in Mpumalanga.
 
Research adding value to the environment by reducing pollution
She explains the focus of her research: “Several production plants and mine waste facilities are located on or near these geological structures which could be a possible cause of ground and surface water pollution. With the aid of geophysical ground surveys (using electromagnetics and electrical resistivity tomography), aquifer and tracer tests, we are trying to determine where the pollution is coming from, how far it has been distributed and to model the potential risks.
 
“This research will add value to the environment by preventing or at least reducing pollution leaking into the environment. Industrial sites always have a negative footprint on the environment but at least we try and contain it by finding the cause of ground and surface water pollution. Thereafter we try and solve the pollution problem or at least mitigate the damage to prevent the spreading of ground and surface water pollution in the area.”
