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.

Prof Riaan Luyt, professor in Chemistry and head of the Natural Sciences Programme at the Qwaqwa Campus of the University of the Free State, received an honorary medal from the Polymer Institute of the Slovak Academy of Sciences on Monday 29 September during a conference in the High Tatras mountains of Slovakia.

During the event Prof Luyt also presented a lecture entitled ‘Paraffin wax in polymer blends and composites: Is it worth investigating?’. In this lecture he gave an overview of the research that he and his group did over a period of 10 years in collaboration with scientists at this institute. The results of this research was published in eighteen international papers and one research book chapter.

Prof Luyt’s research at the Qwaqwa Campus involves polymer blends and composites, and he has already published 82 papers in international, peer reviewed journals, as well as two book chapters. At present his research group consists of nine doctoral and five master’s degree students, as well as a postdoctoral fellow. The postdoctoral fellow is from Nigeria, and one of the doctoral students is from Sudan.

Prof Luyt and his group collaborate formally internationally with groups in Kottayam (India), Modena (Italy), Budapest (Hungary) and Bratislava (Slovakia). He also collaborates informally with groups at the Universities of Pretoria and Stellenbosch, and with a group in Johor Bahru (Malaysia).

He previously received recognition for his research from the Faculty of Natural and Agricultural Sciences at the University of the Free State (Award for Outstanding Research in 2005) and from the Qwaqwa Campus of the UFS (Jubilee Medal and Certificate for Outstanding Research in 2007).
