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 short course on dairy
2010-05-02

The University of the Free State (UFS) will present a one-day short course titled “Adding value to milk and milk products” in the Board Room in the Agriculture Building on the Main Campus in Bloemfontein on Wednesday, 19 May 2010, from 08:15 to 17:00. The cost per person is R950,00 and it includes refreshments, lunch, practical experience and course material. The course will be presented by Prof. Celia Hugo and Dr Maryna de Wit of the UFS.

The after the course the attendants will be able to produce cheese, cottage cheese, feta cheese, maas (Amazi) and yoghurt. In South Africa milk is produced on a large scale.  With the basic knowledge anybody is able to add value to this product by further processing of the milk.

For registration contact Anita at 0836698435 or vwsdairy@ufs.ac.za. Please note that registration closes on 7 May 2010. For more information on the course contact Celia at 0514012692 or hugocj@ufs.ac.za or Maryna at 0514013261 or dewitm@ufs.ac.za.
