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.

“Much has been going wrong in South Africa in the last few years and it’s all due to a lack of strong, visionary leadership. South Africans deserve better and should demand more integrity, courage and vision from the present political leadership,” veteran journalist and author Max du Preez told the audience at a packed Wynand Mouton Theatre at our university, on 25 August 2011.

Delivering this year’s CR Swart Memorial Lecture on the topic “Of Jacob, Julius, Jimmy and the Dancing Monkey”, Du Preez told the audience to look with much more critical eyes at the political leadership and decide who is doing the obvious, following his or her basest instincts or simply trying to play to the gallery. “Why look at a man like Julius Malema and let him upset us, why listen to Floyd Shivambu with his crude manners and let them define us?” Du Preez asked the more than 300 people attending the memorial lecture. The CR Swart Memorial Lecture, the 41st hosted by the UFS, attracted one of the largest crowds ever for a public lecture, with some people sitting on the steps inside the auditorium of the Wynand theatre.
 
Telling the story of African philospher Morena Mohlomi, who acted as a teacher to Basuto king Moshoeshoe, Du Preez told the audience that the country needs counter-intuitive leadership like the two leaders had demonstrated. Calling Mohlomi southern Africa’s first Pan Africanist, Du Preez said the extroadinary thing about Morena Mohlomi and his student was their gift of counter-intuitive leadership, leadership that was daring and visionary, leadership that did not simply do the obvious. Pointing out other visionary leaders like Nelson Mandela, Oliver Tambo, Walter Sisulu, Beyers Naude and Van Zyl Slabbert, Du Preez urged the audience to question “the quality of leadership of Cosatu, the Democratic Teachers Union that is messing up our education, the Communist Party, the Democratic Alliance, the Freedom Front Plus and Solidarity. If they don’t live up to our expectations, why do we still tolerate them?” Du Preez asked.
 
Du Preez also commended Prof. Jonathan Jansen, Vice Chancellor and Rector of the UFS, for his counter-intuitive leadership regarding the Reitz Residence incident and said Prof. Jansen’s solution, as controversial as it was, brought a much better outcome.
