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.

Eusibius McKaiser gives first talk on new book at Kovsies

Students and staff from our university got the first glimpse of political and social commentator Eusibius McKaiser’s new book, There is a Bantu in my bathroom, during a public lecture of the same title held by the author on the Bloemfontein Campus.

McKaiser told the audience that they were amongst the first people to get a preview of his book, a collection of essays on race, sexuality and politics.

His talk centred on domestic race relationships, posing the question whether it was acceptable to have racial preferences with regard to whom you live with. Recounting an incident he encountered while looking for a flat in Sandton, McKaiser said the country was still many kilometres away from the end-goal of non-racialism.

McKaiser, who hosted a weekly politics and morality show on Talk Radio 702, and is a weekly contributor to The New York Times, said the litmus test for non-racialism in South Africa was not what people utter in a public space, but rather what was said in private.

“We need to talk more about the domestic space. In public, we are very insincere and quick to preach non-racialism.”

Recounting conversations he had with Talk Radio 702 listeners on the incident, McKaiser said that preference about whom you live with was not specific to white people’s attitude. He said many of his black listeners also felt uncomfortable living with a white person. “The question is, ‘What do these preferences say about you? What does it say about where we are as a country and people’s commitment to non-racialism?’”

McKaiser was the guest of the International Institute for Studies in Race, Reconciliation and Social Justice.
