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.

CED launches Family Science programme
2009-03-31

 
The Centre for Education Development (CED) at the University of the Free State recently launched a programme that will see 110 students from the Faculty of Education being trained in Family Science. These students will be empowered to assist parents and educators, through community workshops, in achieving further development of learners in the sciences, mathematics, technology and related issues in everyday life through the Family Science programmes that form part of the CED’s Science-For-The-Future project.

They will acquire skills to raise science literacy levels among young children by making use of everyday experiences in and around the home. Furthermore, they will be able to develop learning and teaching materials that are suitable and affordable for use in community workshops, as well as in the formal classroom situation. They will also learn to apply constructivist and hands-on methodology in the teaching of science for young children with different learning styles. As future teachers, they will then be in the privileged position to lay a firm foundation for their learners in the subject area of Natural Sciences, while at the same time reaching out to the community by presenting Family Science workshops that will qualify them for certificates. This project is sponsored by ABSA.

At the launch were, front from the left: Ms Mpai Motloli (Student Educator), Ms Elizna Prinsloo (Project Co-ordinator: CED) and Ms Zine Mogorosi (Regional Manager: ABSA Corporate Social Investment).
