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.

The Bloemfontein Campus of the University of the Free State was abuzz with excitement as first-year students arrived at their new homes and residences, brimming with enthusiasm at starting a new chapter in building towards a professional career.

Although there were some mixed emotions about leaving the nest, most students were excited about the times ahead as they moved into their residences on 20 and 21 January 2017.

Student life and building a career

“I am looking forward to a new adventure, to student life and living at university. Also to build my future here,” said Veruska van Schalkwyk, as her parents, who had driven all the way from Springbok in Northern Cape, helped her unpack at Harmony residence.

Veruska, who will be studying Nursing, said she loved TV programmes like Grey's Anatomy. “Nursing has always been my passion and something I loved. I have always loved helping people.”

University provides a prosperous future

For Okuhle Gubevu, who will also be a first-year in Harmony, the UFS is the ideal place to further her career. “Out of all the research I have done, the University of the Free State is the one university that has a prosperous future for me in my ventures to become an accountant,” she said. “Because of that and because it is not too far from home, I decided on the UFS.”

Mopeli Lebohang will be staying in Outeniqua residence and is keen to work hard. “I heard the course I am studying, B Accounting, is the third toughest course at the university,” he said. “I am excited, because I like challenges.”
