Pioneering greenhouse gas research in South African rainfed agriculture

09 February 2024 | Story EDZANI NEPHALELA | Photo SUPPLIED

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.

Full week of graduation ceremonies at UFS in April

2015-04-10

Autumn always sees the UFS’s first graduation ceremony of the year on the Bloemfontein Campus.

From 14 – 17 April 2015, graduates will once again be rewarded for their hard work while top speakers will address them in the Callie Human Centre. There will be a ceremony at 09:00 and at 14:30 each day on all four days of the graduation.

She is also a Principal Medical Scientist for the National Health Laboratory Service, and a Director for the Human Genome Diversity and Disease Research Unit at the University of Witwatersrand.

During the first ceremony of the day at 09:00, all diplomas/certificates and B degrees in the Faculty of Natural and Agricultural Sciences will be awarded. Only Honours degrees in the Faculty of Natural and Agricultural Sciences will be awarded at the 14:30 ceremony.

Wednesday 15 April 2015:

Wednesday will see Ndumiso Hadebe take the stage to address graduates at both ceremonies.

At the age of 23, Hadebe is the Founder and Managing Director of Master Frontiers Consulting, a firm that capacitates leaders and managers to achieve business goals through their people.

He has been received numerous awards for excellence in leadership, such as the Sedibeng District Municipal Mayor’s Award for Service and Leadership. He is a Brand South Africa Ambassador and Read Educational Trust Ambassador.

All diplomas/certificates, B and Honours degrees in the Faculty of Economic and Management Sciences, except B Com degrees, will be awarded during the morning ceremony at 09:00. Later, at the 14:30 ceremony, only B Com degrees in the Faculty of Economic and Management Sciences will be awarded.

Thursday 16 April 2015:

Multiple award winning South African TV presenter, Leanne Manas, will be the speaker at both Thursday ceremonies.

Manas has graced our screens for over a decade. Not many broadcasters can boast having had live TV experience, 5 days a week for 12 years. She is currently the anchor of SABC 2’s flagship breakfast programme, Morning Live. Leanne is a qualified Speech and Drama teacher. having studied at London Trinity College. She also has an Honours degree in English.
Diplomas/certificates up to and including Honours degrees in the Faculty of the Humanities, Social Sciences, and Communication Sciences will be awarded during the ceremony at 09:00. The 14:30 ceremony will have diplomas/certificates up to and including Honours degrees in the Faculty of the Humanities’ other qualifications except for Social Sciences and Communication Sciences.

Friday 17 April 2015:

Dr Maria Phalime will be the speaker at both ceremonies on Friday.

Phalime is a medical doctor and award-winning author. She practiced for a brief period as a general practitioner in South Africa and the United Kingdom, before leaving medical practice to pursue non-clinical interests. She has worked in trade and investment promotion, and has undertaken research and consulting in the areas of economic development and business facilitation.
