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.

Research conducted on economic impact of recent international soccer and rugby matches for Bloemfontein

2004-09-09

The Centre for Development Support at the University of the Free State (UFS) recently conducted a survey on the economic impact of the international soccer and rugby games that were played in Bloemfontein earlier this year.

The research focused on the soccer match between Bafana Bafana and the Cape Verdic Isle and the rugby match between the Springboks and Ireland .

“The survey was done as a result of a research agenda about local economic development in Bloemfontein ,” said Dr Lochner Marais, researcher at the centre.

“We conducted the research by doing 402 interviews with soccer supporters and 376 interviews with rugby supporters from outside Bloemfontein ,” said Dr Marais.

The centre distributed questionnaires, collecting the following information on the soccer and rugby supporters: their age, gender and origin, the number of nights spend in Bloemfontein , their household expenditure in Bloemfontein and their rating on the quality of service.

“It is estimated that 10 800 soccer supporters and 27 000 rugby supporters came from outside Bloemfontein . Of the rugby supporters 14,4% were female and 85,6% were men. For the soccer international the percentage was 33% females and 67% males,” said Dr Marais.

The highest number of people who came to watch the soccer game in Bloemfontein (35,8%) was from the Northern Free State . The rugby supporters mainly came from Gauteng (21,8%) and the Northern Free State (18%).

When visiting Bloemfontein soccer supporters spend R912 per household, whilst rugby supporters reached deeper in their pockets and spent R1 807 per household.

“The survey indicated that the two international matches resulted in approximately R58 million been spent in Bloemfontein . Rugby supporters were accountable for the largest part (R48 787 205) spent. The largest chunk of the money spent was on accommodation (R14 593 279). On average soccer and rugby supporters from outside Bloemfontein spent 1,4 and 1,9 nights in Bloemfontein ,” said Dr Marais.

Rugby and soccer supporters were also asked to rate the quality of service received from amongst others hotels, guest houses, restaurants, and transport and entertainment facilities. Soccer supporters rated their satisfaction with services higher as rugby supporters. The rugby supporters gave the services at hotels a 3,9 rating, whilst soccer supporters awarded 4,6 rating out of a possible five.
