Dr Jerry Dlamini, lecturer and researcher specialising in agronomy within the Department of Soil, Crop, and Climate Sciences at the University of the Free State (UFS), is at the forefront of pioneering research in this field.

Greenhouse gas emissions represent a significant global concern, driving climate change on a massive scale. This concern is particularly pronounced in rainfed agriculture, where understanding and addressing these emissions are crucial for ensuring sustainable agricultural practices. 

In South Africa, rainfed agriculture is vital in food production, contributing substantially to the nation's agricultural output. However, this sector also stands as a notable contributor to greenhouse gas emissions, primarily through activities such as livestock farming, fertiliser use, and changes in land use.

Dr Jerry Dlamini, a distinguished lecturer and researcher specialising in agronomy within the Department of Soil, Crop, and Climate Sciences at the University of the Free State (UFS), is leading pioneering research in this field. His current project, @CROPGas on X, funded by the European Joint Programme (EPJ), with a budget of R22 million, focuses on investigating the impact of various conservation agriculture interventions on greenhouse gas emissions, primarily targeting nitrous oxide (N2O), methane (CH4), and carbon dioxide (CO2).

This two-year project, which commenced in December 2022 and concludes in December 2024, is a collaborative effort between European and African universities and institutions, including Rothamsted Research (UK), University College Dublin (Ireland), University of Nottingham (UK), University of Poznan (Poland), British Geological Surveys (BGS), University of Zambia (Zambia), University of Zimbabwe, and Lilongwe University of Agriculture and Natural Resources (Malawi). 

Dr Dlamini’s preliminary findings from the UFS Kenilworth Experimental Farm indicate that climate-smart agriculture interventions, such as legume rotation and no-till practices, have the potential to reduce the intensity of greenhouse gas emissions, particularly highly radiative gases like N2O.

“This is a significant finding,” Dr Dlamini noted, “as N2O has a global warming potential 100 times greater than CO2 over a 100-year horizon, meaning its impact on ozone depletion persists far longer despite being emitted in smaller quantities.”

Looking ahead, Dr Dlamini advocates for increased research efforts to quantify greenhouse gas emissions from South African croplands. He emphasises the importance of field-based measurements, akin to methodologies employed by other nations, to enhance the accuracy and effectiveness of South Africa's greenhouse gas inventories submitted annually to the United Nations Framework Convention on Climate Change (UNFCCC) and to devise effective mitigation strategies.

Leah Tutu - from a humble heritage to a matriarch of devotion

There are treasures in life, but owners are few
Of money and power to buy things brand new
Yet you can be wealthy and feel regal too,
If you will just look for the treasures in you …

The joy and the laughter, the smile that you bring;
The heart unafraid to love and to sing;
The hand always willing to help those in need;
Ones quick to reach out, to labour and feed.

So thank you for sharing these great gifts inside;
The caring, the cheering, the hug when one cried.
Thanks for the energy, encouragement too,
And thank you for sharing the treasures in you. (Author unknown)

With these words, Thandeka Tutu-Gxashe embodied the celebration in honour of her mother, Leah Tutu.

On Thursday 17 October 2013, the Annual Intercontinental Leah Tutu Symposium was launched at the UFS’ Bloemfontein Campus. Dignitaries and students alike flocked to the Centenary Hall where friends and family shared their immense love and respect for Ms Tutu.

Approaching the podium, Eunice Dhadhla (co-founder with Ms Tutu of the Domestic Workers Union) started humming and in an instant the audience had risen to their feet and the words “My mother was a kitchen girl. My father was a garden boy. That’s why I’m a unionist”, reverberated through the hall.

“I am what I am today because of her,” Dhadhla said of Ms Tutu. They have walked a long hard road together to ultimately unite domestic workers across the globe. Stretching her small body to its full length, Dhadhla imparted one of the most valuable lessons she has learned from Ms Tutu, “Stop crawling, stand up and walk for yourself.”

As soon as Dr Sindiwe Magona – acclaimed writer and poet – ascended the stage, her energy rushed across the room with electrifying intensity. Her high regard for Ms Tutu as public icon as well as a mother, wife and friend, was palpable. Belting out line after line of a poem she wrote especially for Ms Tutu, the audience echoed their agreement in a mutual exchange.
No sooner were they seated, than Archbishop Desmond Tutu and Prof Jonathan Jansen had the crowd roaring with laughter. Archbishop Tutu’s familiar chuckle peppered his story of how he came to propose to his wife. It was clear, though, how much he reveres Ms Tutu’s presence in his life. With enormous awe, he revealed her innate power, specifically during difficult times in our country’s past – from weathering death threats against her husband to public humiliation.

But despite adversity and heartache, in front of the Centenary Hall, this matriarch stood up and beamed joy into everyone present.
