Pioneering greenhouse gas research in South African rainfed agriculture

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 University of the Free State (UFS) had several highlights in the field of research this year. This includes two A-ratings, which were awarded by the National Research Foundation (NRF) to Prof Maxim Finkelstein from the Department of Mathematics and Actuarial Science, and Prof Melanie Walker, Senior Research Professor and Director of the Centre for Research on Higher Education and Development (CRHED) and DST/NRF Chair in Higher Education and Human Development.

Prof Finkelstein’s A2-rating makes him the only A-rated researcher in ‘Probability and Statistics’ regarding Mathematical Sciences in the country. Prof Walker was evaluated in the division for Research, Innovation Support and Advancement and received an A1-rating.

Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS, considers these ratings as one of the clearest signs that the standard for research across the institution has increased significantly.

Prof Jansen was honoured with the Academy of Science of South Africa’s (ASSAf’s) Science-for-Society Gold Medal for his outstanding achievement in scientific thinking to the benefit of society.

"An award such as this recognises the power of science and scholarship to improve the human condition," Prof Jansen said.

A further highlight at ASSAf’s prestigious annual awards ceremony was the induction of Prof Jeanet Conradie from the Department of Chemistry and Dr Aliza le Roux from the Department of Zoology and Entomology on the UFS’s Qwaqwa Campus as new members of ASSAf.

Prof Conradie was also this year’s first runner-up in the senior category for Distinguished Women Researchers: Physical and Engineering Science in the Department of Science and Technology’s 2014 Women in Science Awards.

Prof Corli Witthuhn: Vice-Rector: Research, describes Prof Conradie as a highly productive researcher who publishes in high-impact journals.

“Not only is she the first female professor in the Department of Chemistry, but she also has extensive international networks and collaboration which elevates the impact of her work even further,” Prof Witthuhn said.

Dr Le Roux is one of ten young researchers inaugurated as members of the South African Young Academy of Science (SAYAS). She was also elected to serve on the executive committee of SAYAS. According to Prof Witthuhn, Dr Le Roux is an outstanding young scientist.

“I am very excited about the young researchers on our Qwaqwa Campus, with Aliza as one of the leaders, and I am looking forward to what they will achieve in the next five years,” she said.
