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.

This year the Faculty of Law at the University of the Free State (UFS) is celebrating a century of excellence in legal education under the theme “Iurisprudentia 100”. A number of prominent leaders in the international legal arena congratulated the faculty on this milestone achievement.

Prof. Harry Rajak, Emeritus Professor from the Sussex Law School at the University of Sussex in the United Kingdom communicated his heartiest congratulations to the faculty. “It has been my great privilege and pleasure to have had, for many years now, a close association with the Faculty of Law of the UFS. I have enjoyed several visits to the Law Faculty, during which I have benefited enormously from the vibrant intellectual, scholarly and extremely friendly atmosphere which you have all created, as well as from the enthusiasm and intelligence of your students. I look forward to the continuation for many more years of this important and fruitful connection,” he said.

Prof. Barry Rider from the Institute of Advanced Legal Studies at the Jesus College at Cambridge University in the UK also congratulated and expressed his admiration towards the faculty. “The reputation for excellence in the teaching of law and in its scholarly research that your faculty has attained both in the Republic and internationally is a testament to the outstanding efforts and commitment of so many generations of scholars in Bloemfontein. I have been extraordinarily privileged to be associated with your faculty. The achievements of your faculty are truly impressive,” he said.

The faculty also received wishes of congratulations from Prof. Thomas Hurst, Research Scholar and Professor of Law from the Levin College of Law at the University of Florida in the United States of America. “The UFS has established itself as a world renowned leader in legal education,” he said.

Mr Anton Trichardt from Londsdale Chambers, Melbourne Australia also conveyed his best wishes to the faculty. “Your Faculty of Law has indeed been an example of excellence in legal education, training and research. The Centre for Business Law and its monograph series has been an unrivalled trend-setter in law,” he said.

Old Mutual also conveyed its wishes of congratulations.
