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.

UFS presents unique rally

2005-06-07

On Friday 10 June 2005, the University of the Free State (UFS) will present the Kovsie version of the Amazing Race in Bloemfontein.

The Amazing Rainbow Rally will be held in aid of children and babies with serious diseases in the Department of Pediatrics and Child Health in the Faculty of Health Sciences.

By raising the necessary funds, equipment can be acquired to meet the unique health care needs of these special patients. It will also enable the UFS to maintain the high standards of education, training and research in this field.

The Amazing Rainbow Rally will give some residents of Bloemfontein an opportunity to test their knowledge of the city, as well as their time management skills, communication skills, team work and even their relationships!

About 12 corporate teams from among others Vodacom, Eskom, Medi-Clinic, Mimosa Mall and Nedbank and four university teams must follow a specific route with various checkpoints by car. Here they will have to complete activities or solve clues before receiving their clue to the next checkpoint. Teams will be traveling with cars branded with the logo of the company they represent.

The rally will start at 09:00 at the Rooiplein of the UFS and will again end on the campus where they will complete the last task. The first team to complete this task is the winner of Bloemfontein’s first Amazing Rainbow Rally.

OFM’s breakfast team will do live crossings on the day to reveal how teams are doing.

The Department of Pediatrics and Child Health at the UFS serves children with special needs, in other words children who need intensive care, or who suffer from cancer, heart disease, neurological diseases and conditions, endocrinological diseases or gastro-enterological conditions.

The Department provides secondary health care to more than 250 000 children in the southern parts of the Free State, but is responsible for the tertiary care of about a million children in the Free State and Northern Cape, as well as some parts of the North-West province, the Eastern Cape and Lesotho. The intensive care units at Universitas and Pelonomi Hospitals serve approximately 1 300 neonatal and 350 intensive care patients annually. The pediatric cardiology unit admits almost 300 high care heart patients per year. Approximately 13 000 out-patients visit these two hospitals every year.
