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.

Rare tumour removed in groundbreaking surgery

A team of surgeons, headed by Prof Francis Smit, Head of our Department of Cardiothoracic Surgery at our Faculty of Health Sciences, performed open heart surgery on a male patient with a malignant tumour.

What makes this operation unique, is that the suspicious mass that was identified in the heart was a rapidly growing and a highly invasive cardiac tumour, which has only been seen in a small number of patients worldwide.

Without the necessary surgery or heart transplant, the prognosis of the patient would have been zero.

The patient, Mr Carl Botes, a 51-year-old farmer from Hoopstad, opted for the tumour to be removed rather than having a heart transplant.  Although both options would involve major risks and challenges, the transplant was the least feasible due to logistics, the waiting list for recipients and the lack of donors.

In the, highly complex, 10-hour operation, performed in the Universitas Academic Hospital in Bloemfontein, the entire right heart chamber had to be removed and the heart reconstructed.

After prolonged hospitalisation of five weeks, Mr Botes was discharged.

Currently he is fully functional and continuing with his active lifestyle.  After three months, all investigations and scans indicate that he is doing very well and has no complaints of fatigue, shortness of breath and palpitations – symptoms which occurred before the removal of the tumour.
