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.

Greyhound racing: Public input needed

2009-02-03

Members of the public have a second opportunity to make submissions regarding the possible legalisation of greyhound racing in South Africa.

A research team from the Faculty of Law at the University of the Free State (UFS), in conjunction with the Department of Trade and Industry (dti), will hold a second round of public consultations in Gauteng, the Free State, North West, the Eastern Cape, the Western Cape and KwaZulu-Natal in February and March this year.

During the first round of consultations last year the research team, under the supervision of Prof. Elizabeth Snyman-Van Deventer of the UFS, received written submissions from interested members of the public and various associations.

The purpose of this research project is to give an objective overview of the greyhound racing industry nationally as well as internationally. This includes aspects such as animal welfare, social, economical and political issues and the legal framework pertaining to greyhound racing.

The study focuses on the current situation in South Africa and internationally regarding the jurisdictions where the sport is currently active and the current legal framework.

It will also include a comparative study of the situation in countries such as the United States of America, Ireland, England, Belgium, Australia, New Zealand, Canada and Vietnam.

Greyhound racing was banned in South Africa years ago because gambling was regarded as immoral at that time. Now that gambling has been legalised and is regulated there are debates on the legislation of greyhound racing.

The animal welfare and protection groups are against the legalisation of greyhound racing, while other role players have been calling for the racing to be legalised and regulated.

The public consultations will take place as follows:

• 6 February 2009, 09:00-12:30, Protea Edward Hotel, Durban
• 13 February 2009, 09:00-12:30, Protea Sea Point Hotel, Cape Town
• 20 February 2009, 09:00-12:30, Protea Marine Hotel, Port Elizabeth
• 26 February 2009, 09:00-12:30, Garden Court Hotel, Bloemfontein
• 27 February 2009, 09:00-12:30, Protea Manor Hotel, Hatfield, Pretoria
• 6 March 2009, 09:00-12:30, Garden Court East London, Esplanade, East London
• 13 March 2009, 09:00-12:30, Willows Garden Hotel, Potchefstroom

For further information, members of the public who are interested in attending these consultations should contact Mpho Mosing of the dti at 012 394 1504/083 436 5534 or Prof. Snyman-Van Deventer at 051 401 2698 or e-mail it to snymane.rd@ufs.ac.za
